 ## Key Patterns
 
-- **Store layer:** Interface-based (`store.SessionStore`, `store.AgentStore`, etc.) with pg/ (PostgreSQL) implementations. Uses `database/sql` + `pgx/v5/stdlib`, raw SQL, `execMapUpdate()` helper in `pg/helpers.go`
+- **Store layer:** Interface-based (`store.SessionStore`, `store.AgentStore`, etc.) with shared Dialect pattern in `store/base/`. PostgreSQL (`pg/`) and SQLite (`sqlitestore/`) implementations use `database/sql` + `pgx/v5/stdlib` + sqlx, raw SQL, `BuildMapUpdate()` and `BuildScopeClause()` helpers
 - **Agent types:** `open` (per-user context, 7 files) vs `predefined` (shared context + USER.md per-user)
 - **Context files:** `agent_context_files` (agent-level) + `user_context_files` (per-user), routed via `ContextFileInterceptor`
-- **Providers:** Anthropic (native HTTP+SSE), OpenAI-compat (HTTP+SSE), DashScope (Alibaba Qwen), Claude CLI (stdio+MCP bridge), ACP (Anthropic Console Proxy), Codex (OpenAI). All use `RetryDo()` for retries. Loads from `llm_providers` table with encrypted API keys
-- **Agent loop:** `RunRequest` → think→act→observe → `RunResult`. Events: `run.started`, `run.completed`, `chunk`, `tool.call`, `tool.result`. Auto-summarization at >85% context (token-based only)
-- **Context propagation:** `store.WithAgentType(ctx)`, `store.WithUserID(ctx)`, `store.WithAgentID(ctx)`, `store.WithLocale(ctx)`
-- **WebSocket protocol (v3):** Frame types `req`/`res`/`event`. First request must be `connect`
+- **Providers:** Anthropic (native HTTP+SSE), OpenAI-compat (HTTP+SSE), DashScope (Alibaba Qwen), Claude CLI (stdio+MCP bridge), ACP (Anthropic Console Proxy), Codex (OpenAI). All use `RetryDo()` for retries. Loads from `llm_providers` table with encrypted API keys. ProviderAdapter enables pluggable implementations with ModelRegistry forward-compat resolver. Shared SSEScanner in `providers/sse_reader.go` for streaming providers
+- **Pipeline:** 8-stage loop (context→history→prompt→think→act→observe→memory→summarize) with pluggable callbacks, always-on execution path
+- **DomainEventBus:** Typed events with worker pool, dedup, retry. Used by consolidation pipeline and memory workers
+- **3-tier memory:** Working (conversation) → Episodic (session summaries) → Semantic (KG). Progressive loading L0/L1/L2 with auto-inject for L0
+- **Knowledge Vault:** Document registry + [[wikilinks]] + hybrid search, query layer above existing stores, FS sync, unified search
+- **Context propagation:** `store.WithAgentType(ctx)`, `store.WithUserID(ctx)`, `store.WithAgentID(ctx)`, `store.WithLocale(ctx)`, `store.WithTenantID(ctx)`
+- **Request middleware:** Composable chain (cache, service tier, request guards), zero-alloc fast path for hot operations
+- **Self-evolution:** Metrics → suggestions → auto-adapt. 3 progressive stages: metrics collection, suggestion analysis, guardrail-protected apply/rollback
+- **Orchestration:** Delegate tool for inter-agent task delegation with agent_links, 3 delegation modes (auto/explicit/manual), token-aware work distribution. BatchQueue[T] generic for result aggregation
+- **WebSocket protocol:** Frame types `req`/`res`/`event`. First request must be `connect`
 - **Config:** JSON5 at `GOCLAW_CONFIG` env. Secrets in `.env.local` or env vars, never in config.json
 - **Security:** Rate limiting, input guard (detection-only), CORS, shell deny patterns, SSRF protection, path traversal prevention, AES-256-GCM encryption. All security logs: `slog.Warn("security.*")`
 - **Telegram formatting:** LLM output → `SanitizeAssistantContent()` → `markdownToTelegramHTML()` → `chunkHTML()` → `sendHTML()`. Tables rendered as ASCII in `<pre>` tags

 - Use `switch/case` instead of `if/else if` chains on the same variable
 - Use `append(dst, src...)` instead of loop-based append
 - Always handle errors; don't ignore return values
-- **Migrations:** When adding a new SQL migration file in `migrations/`, bump `RequiredSchemaVersion` in `internal/upgrade/version.go` to match the new migration number
+- **Migrations (dual-DB):** PostgreSQL and SQLite have **separate migration systems**. When adding schema changes: (1) PG: add SQL in `migrations/` + bump `RequiredSchemaVersion` in `internal/upgrade/version.go`. (2) SQLite: update `internal/store/sqlitestore/schema.sql` (full schema for fresh DBs) + add incremental patch in `schema.go` `migrations` map + bump `SchemaVersion` constant. **Always update both** — missing SQLite migrations cause desktop edition to crash on startup
 - **i18n strings:** When adding user-facing error messages, add key to `internal/i18n/keys.go` and translations to `catalog_en.go`, `catalog_vi.go`, `catalog_zh.go`. For UI strings, add to all locale JSON files in `ui/web/src/i18n/locales/{en,vi,zh}/`
 - **SQL safety:** When implementing or modifying SQL store code (`store/pg/*.go`), always verify: (1) All user inputs use parameterized queries (`$1, $2, ...`), never string concatenation — prevents SQL injection. (2) Queries are optimized — no N+1 queries, no unnecessary full table scans. (3) WHERE clauses, JOINs, and ORDER BY columns use existing indices — check migration files for available indexes
 - **DB query reuse:** Before adding a new DB query for key entities (teams, agents, sessions, users), check if the same data is already fetched earlier in the current flow/pipeline. Prefer passing resolved data through context, event payloads, or function params rather than re-querying. Duplicate queries waste DB resources and add latency

 ## Multi-Agent Orchestration
 
-GoClaw supports agent teams and inter-agent delegation — each agent runs with its own identity, tools, LLM provider, and context files.
-
-### Agent Delegation
-
 <p align="center">
-  <img src="_statics/agent-delegation.jpg" alt="Agent Delegation" width="700" />
+  <img src="_statics/Agent Orchestration.jpg" alt="Agent Orchestration" width="800" />
 </p>
 
-| Mode | How it works | Best for |
-|------|-------------|----------|
-| **Sync** | Agent A asks Agent B and **waits** for the answer | Quick lookups, fact checks |
-| **Async** | Agent A asks Agent B and **moves on**. B announces later | Long tasks, reports, deep analysis |
+Each agent runs with its own identity, tools, LLM provider, and context files. Three delegation modes — sync (wait), async (fire-and-forget), bidirectional — connected through explicit permission links with concurrency limits.
 
-Agents communicate through explicit **permission links** with direction control (`outbound`, `inbound`, `bidirectional`) and concurrency limits at both per-link and per-agent levels.
+> Details: [Agent Teams docs](https://docs.goclaw.sh/#teams-what-are-teams)

-- **Shared task board** — Create, claim, complete, search tasks with `blocked_by` dependencies
-- **Tools**: `team_tasks` for task management, `spawn` for subagent orchestration
+Document registry with `[[wikilinks]]` for bidirectional linking. Hybrid search combines full-text (BM25) and semantic (pgvector) for precise retrieval. Filesystem sync keeps vault in sync with on-disk files.

+## Self-Evolution
+
+<p align="center">
+  <img src="_statics/Self-Evolution System.jpg" alt="Self-Evolution" width="800" />
+</p>
+
+Agents improve themselves through a 3-stage guardrailed pipeline: metrics collection → suggestion analysis → auto-adaptation. Can refine communication style and domain expertise (CAPABILITIES.md) — but never change identity, name, or core purpose.
+
+## Provider Adapters
+
+<p align="center">
+  <img src="_statics/Provider Adapter System.jpg" alt="Provider Adapters" width="800" />
+</p>
+
+20+ LLM providers unified through a single adapter interface. Capability-based routing, encrypted API keys (AES-256-GCM), extended thinking support per-provider, and prompt caching for Anthropic + OpenAI.
+
+## Event-Driven Architecture
+
+<p align="center">
+  <img src="_statics/DomainEventBus.jpg" alt="DomainEventBus" width="800" />
+</p>
+
+Typed domain events power the consolidation pipeline — session summaries, knowledge graph extraction, and dreaming promotion all run asynchronously via worker pools with dedup and retry.

+## V3 Architecture (Wave 1 & Wave 2 - dev-v3 branch)
+
+### Overview
+
+V3 introduces a **pluggable 8-stage pipeline** (replacing the monolithic `runLoop`), an event-driven architecture via `DomainEventBus`, and advanced memory consolidation. The system maintains backward compatibility via a **dual-mode gate** at the loop level: agents can opt into v3 pipeline or stay on v2 monolithic loop per-agent via `other_config` JSONB.
+
+### 8-Stage Pipeline
+
+| Stage | Phase | Responsibility |
+|-------|-------|-----------------|
+| **ContextStage** | Setup (once) | Inject agent/user/workspace context, compute per-user files |
+| **ThinkStage** | Iteration | Build system prompt, filter tools by policy, call LLM |
+| **PruneStage** | Iteration | Context pruning (2-pass: soft trim → hard clear), run memory flush if compaction triggered |
+| **ToolStage** | Iteration | Execute tool calls (parallel goroutines for multiple calls) |
+| **ObserveStage** | Iteration | Process tool results, append to messages |
+| **CheckpointStage** | Iteration | Track iteration state, check for loop exit conditions |
+| **FinalizeStage** | Finalize (once) | Sanitize output, flush messages, update session metadata |
+
+### Feature Flags (in `agents.other_config` JSONB)
+
+| Flag | Key | Type | Default | Purpose |
+|------|-----|------|---------|---------|
+| Pipeline | `v3_pipeline_enabled` | bool | false | Use v3 pipeline instead of v2 monolithic loop |
+| Memory | `v3_memory_enabled` | bool | false | Enable episodic/semantic consolidation workers via DomainEventBus |
+| Retrieval | `v3_retrieval_enabled` | bool | false | Enable Knowledge Vault with wikilinks + hybrid search, L0 auto-injection |
+| Evolution Metrics | `self_evolution_metrics` | bool | false | Track agent metrics for evolution suggestions (tool usage, retrieval patterns) |
+| Evolution Suggestions | `self_evolution_suggestions` | bool | false | Generate and apply evolution suggestions (auto-adapt prompt/tools) |
+
+### Memory Consolidation System
+
+**DomainEventBus** drives asynchronous consolidation:
+
+- **Episodic Worker** — Extracts facts from recent runs, clusters by topic, stores in `episodic_memory` table with embeddings
+- **Semantic Worker** — Reprocesses episodic clusters, generates abstracted summaries, produces `semantic_memory` entries
+- **Dreaming Worker** — Synthesizes novel insights from memory clusters, cross-links related memories, drives self-evolution
+- **Dedup Worker** — Prevents duplicate memory entries, maintains consistency across consolidation cycles
+
+### Workspace Context Resolver
+
+Six distinct workspace scenarios:
+
+1. **Agent default** — Agent workspace from config, sandbox environment
+2. **Team lead** — Team workspace as default (agent coordinates tasks)
+3. **Team member** — Agent workspace with team workspace accessible via `WithToolTeamWorkspace()`
+4. **Dispatch** — Temporary workspace from `req.TeamWorkspace` (one-off delegated task)
+5. **Subagent** — Inherited workspace from parent agent via context propagation
+6. **Cron** — Workspace resolved from agent + timezone context at cron trigger time
+
+### Knowledge Vault (Wikilinks + Hybrid Search)
+
+- **Wikilinks**: Bidirectional semantic links (`[[related-concept]]`) automatically extracted from memories
+- **Hybrid Search**: BM25 keyword search + vector similarity (pgvector) combined via RRF (reciprocal rank fusion)
+- **L0 Auto-Injection**: Top-K vault entries injected into system prompt as "relevant context from vault"
+- **Filesystem Sync**: Vault entries exported as `.md` files for manual editing, re-imported with change tracking

 ## Overview
 
-The Agent Loop implements a **Think --> Act --> Observe** cycle. Each agent owns a `Loop` instance configured with a provider, model, tools, workspace, and agent type. A user message enters as a `RunRequest`, passes through `runLoop`, and exits as a `RunResult`. The loop iterates up to 20 times: the LLM thinks, optionally calls tools, observes results, and repeats until it produces a final text response.
+The Agent Loop implements a **Think --> Act --> Observe** cycle. Each agent owns a `Loop` instance configured with a provider, model, tools, workspace, and agent type. A user message enters as a `RunRequest`, passes through the loop, and exits as a `RunResult`. 
+
+**V3 Dual Mode**: The loop supports two execution paths:
+- **V2 (monolithic)**: Original `runLoop()` function (default for backward compatibility)
+- **V3 (pipeline)**: Pluggable 8-stage pipeline (`internal/pipeline/`, enabled via feature flag)
+
+Both paths implement the same external behavior; the difference is internal architecture. The loop iterates up to 20 times: the LLM thinks, optionally calls tools, observes results, and repeats until it produces a final text response.
 
 ---
 
-## 1. RunRequest Flow
+## V3 Pipeline Architecture
+
+When `pipeline_enabled` is true, `Loop.Run()` delegates to `runViaPipeline()`, which orchestrates the v3 pipeline:
+
+```mermaid
+flowchart TD
+    RUN["Loop.Run<br/>runRequest"] --> GATE{pipeline_enabled?}
+    GATE -->|false| V2["runLoop<br/>v2 monolithic"]
+    GATE -->|true| V3["runViaPipeline<br/>v3 pipeline"]
+
+    V3 --> NEWSTATE["NewRunState<br/>input, nil, model, provider"]
+    NEWSTATE --> NEWPIPE["NewDefaultPipeline<br/>8 stages"]
+    NEWPIPE --> PIPE_RUN["Pipeline.Run<br/>setup → iteration loop → finalize"]
+
+    PIPE_RUN --> CONVERT["convertRunResult<br/>pResult → RunResult"]
+    CONVERT --> RESULT["RunResult"]
+```
+
+### Stage Execution Order
+
+```
+Setup (runs once)
+├─ ContextStage: Inject context, compute workspace, ensure per-user files
+│
+Iteration Loop (max 20 iterations)
+├─ ThinkStage: Build system prompt, filter tools, call LLM
+├─ PruneStage: Soft/hard trim context, run memory flush if needed
+├─ ToolStage: Execute tool calls (parallel)
+├─ ObserveStage: Process tool results, append messages
+└─ CheckpointStage: Check iteration state, conditionally break
+
+Finalize (runs once, uses background context if cancelled)
+└─ FinalizeStage: Sanitize output, flush messages, update metadata
+```
+
+### Stage Details
+
+**ContextStage**
+- Inject context: `WithAgentID()`, `WithUserID()`, `WithAgentType()`, `WithLocale()`
+- Resolve per-user workspace (base + sanitized userID)
+- Ensure per-user files exist (idempotent via `sync.Map` cache)
+- Persist agent/user IDs on session
+
+**ThinkStage**
+- Resolve workspace + context files dynamically
+- Build system prompt (15+ sections)
+- Inject conversation summary if exists
+- Run history pipeline (limitHistoryTurns → pruneContextMessages → sanitizeHistory)
+- Filter tools through PolicyEngine (RBAC)
+- Call LLM, record span with token counts
+- Emit `chunk` events (streaming) or single response
+
+**PruneStage**
+- Estimate token ratio vs context window
+- If >= 30%, run soft trim pass (keep first/last 1500 chars, replace middle with "...")
+- If >= 50%, run hard clear pass (replace with placeholder)
+- Trigger memory flush (synchronous) if compaction threshold exceeded
+
+**ToolStage**
+- Execute single tool sequentially (no goroutine overhead)
+- Execute multiple tools in parallel via goroutines, sort results by index
+- Emit `tool.call` before, `tool.result` after
+- Record tool span
+- Append tool messages to buffer
+
+**ObserveStage**
+- Process tool result stream
+- Handle `NO_REPLY` convention (silent completion)
+- Append assistant message with tool call info
+
+**CheckpointStage**
+- Increment iteration counter
+- Check if max iterations reached → `BreakLoop`
+- Check if context cancelled → `AbortRun`
+
+**FinalizeStage**
+- Run 7-step output sanitization pipeline
+- Flush buffered messages atomically
+- Update session metadata (model, provider, token counts)
+- Emit `run.completed` or `run.failed` event
+
+---
+
+## Orchestration Modes
+
+Agents support three orchestration modes that determine which inter-agent tools are available:
+
+### ModeSpawn (Default)
+- **Use case**: Single independent agent
+- **Tools available**: `spawn` (self-clone child agents)
+- **Tools hidden**: `delegate`, `team_tasks`
+- **Resolution**: Default when no team or delegate links
+
+### ModeDelegate
+- **Use case**: Agent with linked delegate targets
+- **Tools available**: `spawn`, `delegate` (dispatch to linked agents)
+- **Tools hidden**: `team_tasks`
+- **Resolution**: When `agent_links` table has rows with source = this agent
+
+### ModeTeam
+- **Use case**: Agent in a team (multiple agents collaborating)
+- **Tools available**: `spawn`, `delegate`, `team_tasks` (full team workspace)
+- **Tools hidden**: None
+- **Resolution**: When `teams` table has a row with agent_id = this agent
+
+**Mode Resolution Priority**: Team > Delegate > Spawn
+
+The system prompt includes relevant details for each mode (delegate targets, team context, shared workspace paths).
+
+---
+
+## Self-Evolution System
+
+Agents can auto-adapt their behavior based on metrics and admin-approved suggestions.
+
+### Evolution Suggestion Engine
+
+Analyzes agent metrics on a periodic schedule (cron job):
+
+1. **LowRetrievalUsageRule** — Detects if `memory_search` or `knowledge_graph_search` is underutilized; suggests enabling vault
+2. **ToolFailureRule** — Identifies frequently failing tools; suggests limiting tool set or retraining
+3. **RepeatedToolRule** — Detects repetitive tool calls (loop detection); suggests prompt adjustment
+
+### Adaptation Guardrails
+
+**AdaptationGuardrails** struct controls safety limits (stored in `agents.other_config.evolution_guardrails`):
+
+| Field | Default | Purpose |
+|-------|---------|---------|
+| `max_delta_per_cycle` | 0.1 | Max parameter change per cycle (prevents wild swings) |
+| `min_data_points` | 100 | Require at least N metrics before applying suggestion |
+| `rollback_on_drop_pct` | 20.0 | Revert if quality drops >20% after applying |
+| `locked_params` | [] | Parameter names that cannot auto-change (e.g., "temperature") |
+
+### Suggestion Workflow
+
+1. **SuggestionEngine.Analyze()** evaluates rules against 7-day metrics window
+2. Generates `EvolutionSuggestion` records (status="pending")
+3. Admin reviews in dashboard, approves/rejects
+4. On approval, auto-adapt worker applies suggestion + records baseline metrics
+5. Next cycle detects quality regression and auto-rolls back if threshold exceeded

+## 13. Wave 2: Provider Resilience (v3)
+
+GoClaw v3 Wave 2 adds composable request middleware, error classification, per-model cooldown, and 2-tier failover for production resilience.
+
+**Request Middleware** — Transforms provider requests in composable pipeline. Built-in: `CacheMiddleware` (prompt caching), `ServiceTierMiddleware` (routing hints), `RateLimitMiddleware` (quota management). Zero-alloc fast path: `ComposeMiddlewares` returns nil if all inputs nil.
+
+**Error Classification** — Maps provider errors to 9 canonical reasons: `FailoverAuth`, `FailoverAuthPermanent`, `FailoverRateLimit`, `FailoverOverloaded`, `FailoverBilling`, `FailoverFormat`, `FailoverModelNotFound`, `FailoverTimeout`, `FailoverUnknown`. `DefaultClassifier` pattern-matches body strings (OpenAI, Anthropic pre-registered). Detects context overflow (triggers auto-compaction).
+
+**Cooldown Tracking** — `CooldownTracker` in-memory state machine. Per-reason durations: 30s (rate limit), 60s→120s escalated (overloaded), 10m (auth), 1h (permanent auth/model not found), 15s (timeout), 5m (billing). Auto-decay 24h TTL; probe interval ≥30s.
+
+**2-Tier Failover** — `RunWithFailover[T]`: Tier 1 rotates API profiles for transient errors (≤5 rotations); Tier 2 falls back to next model for permanent errors. Returns all attempts with classifications. Exhausted → `FailoverSummaryError`.
+
+**Model Registry** — Thread-safe forward-compat resolver. Seeds Claude, GPT, Qwen models. Each spec: context window, max tokens, reasoning/vision flags, per-1M cost. Unknown models → provider's `ForwardCompatResolver` (caches hit). Template cloning with patch overrides.
+
+**Embedding Providers** — OpenAI (text-embedding-3-small, 1536 dims, batch 2048) and Voyage AI (1024 dims, batch 1024) via `store.EmbeddingProvider`. Used by vault and episodic memory. All vectors normalized to 1536 for pgvector column.

+
+const (
+	CapReadOnly   ToolCapability = "read-only"    // no side effects
+	CapMutating   ToolCapability = "mutating"     // modifies state
+	CapAsync      ToolCapability = "async"        // returns immediately
+	CapMCPBridged ToolCapability = "mcp-bridged"  // proxied to external MCP
+)

+	Group             string // "fs", "web", "runtime", "memory", "team", etc.
+	RequiresWorkspace bool
+	ProviderHints     map[string]any
+}
+```
+
+**Default capability inference** (based on tool name):
+- **Read-only**: `read_file`, `list_files`, `memory_search`, `memory_expand`, `web_fetch`, `skill_search`, `knowledge_graph_search`, `sessions_history`, `datetime`, `web_search`, `read_image`, `read_audio`, `read_video`, `read_document`
+- **Async**: `spawn` (subagent spawning)
+- **Mutating**: All other tools (write, exec, message, team tasks, etc.)
+
+Metadata enables capability-aware tool filtering (e.g., restrict agents to read-only tools, gate async operations).

-## 7. Delegation System
+## 7. Delegation System (v3)
 
-> **Note:** The `delegate` tool has been removed. The `DelegateManager` described below is deprecated/removed. Delegation is now handled via agent teams: leads create tasks on the shared board (`team_tasks`) and spawn member agents explicitly. See [11-agent-teams.md](11-agent-teams.md) for the current model.
+The `delegate` tool enables inter-agent task delegation using agent_links for permission management. Unlike subagents (anonymous clones), delegation crosses agent boundaries to fully independent agents with distinct identities, tools, providers, and context files.
 
-Delegation allows named agents to delegate tasks to other fully independent agents (each with its own identity, tools, provider, model, and context files). Unlike subagents (anonymous clones), delegation crosses agent boundaries via explicit permission links.
+### Delegate Tool
 
-### DelegateManager (Removed)
+Invoked with agent_key, task, mode (async/sync), and optional timeout:
 
-The `delegate` tool and its `DelegateManager` in `internal/tools/subagent_spawn_tool.go` have been removed. Previously supported actions:
+```json
+{
+  "agent_key": "data-analyst",
+  "task": "Analyze Q3 sales trends",
+  "mode": "sync",
+  "timeout": 300
+}
+```
 
-| Action | Mode | Behavior |
-|--------|------|----------|
-| `delegate` | `sync` | Caller waits for result (quick lookups, fact checks) |
-| `delegate` | `async` | Caller moves on; result announced later via message bus (`delegate:{id}`) |
-| `cancel` | -- | Cancel a running async delegation by ID |
-| `list` | -- | List active delegations |
-| `history` | -- | Query past delegations from `delegation_history` table |
+**Modes:**
+- **async** (default) — Fire-and-forget; result announced via message bus as `delegate:{delegationID}`. No blocking.
+- **sync** — Block up to timeout seconds; return result directly. Max timeout: 600s.
 
-### Callback Pattern
+### Permission Model
 
-The `tools` package cannot import `agent` (import cycle). A callback function bridges the gap:
+Delegation requires an `agent_link` from caller → target. Link status checked at runtime:
 
 ```go
-type AgentRunFunc func(ctx context.Context, agentKey string, req DelegateRunRequest) (*DelegateRunResult, error)
+allowed, err := links.CanDelegate(ctx, fromAgentID, toAgentID)
 ```
 
-The `cmd` layer provides the implementation at wiring time. The `tools` package never knows `agent` exists.
+If link missing or disabled, returns *"no delegation link from current agent to '{targetKey}'"*.
 
-### Concurrency Control
+### Event Emission
 
-Delegation concurrency is controlled at the agent level to prevent overload:
+Emits `delegate.sent` event with delegation ID, from/to agents, task description, and mode. Enables audit trails and async result routing.
 
-| Layer | Config | Scope |
-|-------|--------|-------|
-| Per-agent | `other_config.max_delegation_load` | B from all sources |
+### Coordination with Teams
 
-When limits hit, the error message is written for LLM reasoning: *"Agent at capacity (5/5). Try a different agent or handle it yourself."*
-
-### DELEGATION.md Auto-Injection
-
-During agent resolution, `DELEGATION.md` is auto-generated and injected into the system prompt:
-
-- **≤15 targets**: Full inline list with agent keys, names, and frontmatter
-- **>15 targets**: Brief description-only list (LLM reads available delegation targets via resolver)
-
-### Context File Merging (Open Agents)
-
-For open agents, per-user context files merge with resolver-injected base files. Per-user files override same-name base files, but base-only files like `DELEGATION.md` are preserved:
-
-```
-Base files (resolver):     DELEGATION.md
-Per-user files (DB):       AGENTS.md, SOUL.md, TOOLS.md, USER.md, ...
-Merged result:             AGENTS.md, SOUL.md, TOOLS.md, USER.md, ..., DELEGATION.md ✓
-```
+Delegation is independent of teams. However, team leads often delegate to team members rather than spawning. For structured workflows with shared task board, use agent teams instead (see [11-agent-teams.md](11-agent-teams.md)).

+## 17. V3 Three-Tier Memory & Auto-Injection (New in v3)
+
+V3 introduces a comprehensive 3-tier memory system with event-driven consolidation and intelligent auto-injection.
+
+### Architecture Overview
+
+**Working Memory (L0):** Current conversation in `sessions.messages`. Auto-compacted via summarization at context threshold.
+
+**Episodic Memory (L1):** Session summaries stored in `episodic_summaries` table with:
+- Full summary + ~50-token L0 abstract (pre-computed)
+- Embedding vector for hybrid search
+- Key topics array for quick filtering
+- 90-day retention by default
+
+**Semantic Memory (L2):** Knowledge Graph in `kg_entities` + `kg_relations` with temporal validity (`valid_from`, `valid_until`). Long-term structured knowledge.
+
+### Auto-Injection (L0 Loading)
+
+Runs in ContextStage once per turn. Checks user message against episodic index. If relevant matches found, injects L0 abstracts into system prompt.
+
+**Config** (stored in agent settings):
+```json
+{
+  "auto_inject_enabled": true,
+  "auto_inject_threshold": 0.3,
+  "auto_inject_max_tokens": 200,
+  "episodic_ttl_days": 90,
+  "consolidation_enabled": true
+}
+```
+
+**Return value:** Formatted section (~200 tokens max) with top K summaries, or empty string if no relevant matches.
+
+### Progressive Tool Access

+Three tool-based memory interactions:
+
+| Tool | Purpose | Tier | Example |
+|------|---------|------|---------|
+| (auto-inject) | Automatic context injection | L0 | System prompt includes 3 relevant past sessions |
+| `memory_search(query)` | Hybrid search L1 + L2 | L1 | "Find past discussions about billing" |
+| `memory_expand(id)` | Deep retrieval from episodic | L2 | "Show me full summary + linked facts from session XYZ" |
+
+---
+
+## 18. Consolidation Pipeline (Event-Driven Workers)
+
+After a session ends (`run.completed` event), async workers extract and consolidate memory into long-term storage.
+
+```mermaid

+    DREAM --> SYNTH["Long-term<br/>memory output"]
+```
+
+### Worker Responsibilities
+
+**EpisodicWorker** (`internal/consolidation/episodic_worker.go`):
+1. Listens to `run.completed` events
+2. Checks for duplicate via `source_id` = `session_key:compaction_count`
+3. Uses compaction summary if available, else calls LLM to summarize
+4. Generates L0 abstract via `generateL0Abstract()` (~50 tokens)
+5. Extracts entity names via `extractEntityNames()`
+6. Sets 90-day expiry
+7. Stores in `episodic_summaries`
+8. Publishes `episodic.created` for downstream workers
+
+**SemanticWorker** (`internal/consolidation/semantic_worker.go`):
+1. Listens to `episodic.created` events
+2. Parses summary for entity mentions + relationships
+3. Inserts entities into `kg_entities` with confidence score
+4. Inserts relations into `kg_relations`
+5. Publishes `entity.upserted` for dedup
+
+**DedupWorker** (`internal/consolidation/dedup_worker.go`):
+1. Listens to `entity.upserted` events
+2. Searches for similar entities via embedding cosine distance
+3. Merges duplicates by redirecting relations
+4. Updates consolidation timestamps
+
+**DreamingWorker** (`internal/consolidation/dreaming_worker.go`):
+1. Listens to `episodic.created` events with 10-minute debounce
+2. Collects unpromoted episodic summaries (limit: configurable, default 10)
+3. Calls LLM for batch synthesis/insight pass
+4. Writes results to long-term storage (vault, KG expansion, etc.)
+5. Marks summaries as promoted via `MarkPromoted()`
+
+### Consolidation Flow
+
+| Stage | Event | Worker | Output |
+|-------|-------|--------|--------|
+| 1 | `run.completed` | EpisodicWorker | `episodic_summaries` row + `episodic.created` |
+| 2 | `episodic.created` | SemanticWorker | `kg_entities` + `kg_relations` rows + `entity.upserted` |
+| 3 | `entity.upserted` | DedupWorker | Merged KG nodes |
+| 4 | `episodic.created` (debounced) | DreamingWorker | Promoted episodic + synthetic memory |
+
+---
+
+## 19. Episodic Summaries Table Schema
+
+| Column | Type | Purpose |
+|--------|------|---------|
+| `id` | UUID | Primary key |
+| `tenant_id` | UUID | Multi-tenant scope |
+| `agent_id` | UUID | Agent owner |
+| `user_id` | VARCHAR(255) | Chat participant (empty for team) |
+| `session_key` | TEXT | Reference to original session |
+| `summary` | TEXT | Full conversation summary (2-4 paragraphs) |
+| `l0_abstract` | TEXT | Short abstract (~50 tokens) for auto-inject |
+| `key_topics` | TEXT[] | Extracted entity names for filtering |
+| `embedding` | vector(1536) | Vector embedding of full summary |
+| `source_type` | TEXT | "session", "v2_daily", "manual" |
+| `source_id` | TEXT | Dedup key (unique per source) |
+| `turn_count` | INT | Message count in session |
+| `token_count` | INT | Total tokens used |
+| `created_at` | TIMESTAMPTZ | Creation timestamp |
+| `expires_at` | TIMESTAMPTZ | Auto-expiry (90 days default) |
+
+**Indexes:** GIN on `to_tsvector`, HNSW on embedding, unique on `(agent_id, user_id, source_id)`, on `(agent_id, user_id)` for scoped queries.
+
+---
+
+## 20. Knowledge Graph Temporal Validity
+
+Migration 000037 adds temporal columns to KG tables for time-bounded facts.
+
+**Added columns:**
+- `valid_from` (TIMESTAMPTZ, default NOW()) — when fact becomes true
+- `valid_until` (TIMESTAMPTZ, nullable) — when fact expires (NULL = current)
+
+**Usage pattern:**
+```sql
+-- Query only current facts
+SELECT * FROM kg_entities 
+WHERE agent_id = $1 AND valid_until IS NULL;
+
+-- Query facts valid at point in time
+SELECT * FROM kg_entities
+WHERE agent_id = $1 
+  AND valid_from <= $2 
+  AND (valid_until IS NULL OR valid_until > $2);
+```
+
+**Benefits:**
+- Track fact lifecycle (learned → updated → deprecated)
+- Support temporal reasoning ("what did we know in January?")
+- Auto-expire outdated information via DedupWorker consolidation

-## 11. Delegation Context
+## 11. Agent Links & Delegation Graph (v3)
+
+Agent links define directed delegation relationships between agents, separate from team membership. Each link tracks:
+- **Source agent** (can delegate to)
+- **Target agent** (can receive delegations from)
+- **Direction** (outbound from source, inbound to target)
+- **Team context** (optional `team_id` if created by team setup)
+- **Concurrency limit** (max simultaneous delegations for this link)
+
+**Team-created links** are automatically created when a team is set up (lead → each member). Links remain even if the team is deleted or members are removed, allowing manual cleanup.
+
+**Delegation graph visibility** — agents can query available delegation targets via the delegation system. The graph determines which agents appear in the `spawn` tool's available targets.

 ## [Unreleased]
 
+### Refactored
+
+#### V3 Architecture Refactor — Phase 6 Completion (2026-04-08)
+- **Store unification**: Created `internal/store/base/` with shared Dialect interface, common helpers (NilStr, BuildMapUpdate, BuildScopeClause, execMapUpdate, etc.). PostgreSQL (`pg/`) and SQLite (`sqlitestore/`) now use base/ abstractions via type aliases, eliminating code duplication
+- **Orchestration module**: New `internal/orchestration/` with orchestration primitives: BatchQueue[T] generic for result aggregation, ChildResult structure for capturing child agent outputs, media conversion helpers
+- **Forced V3 pipeline**: Deleted legacy v2 `runLoop()` (~745 LOC). Removed `v3PipelineEnabled` conditional flag — all agents now always execute the unified 8-stage pipeline (context→history→prompt→think→act→observe→memory→summarize)
+- **Gateway decomposition**: Split monolithic gateway.go (1295 LOC → 476 LOC) into focused modules: gateway_deps.go, gateway_http_wiring.go, gateway_events.go, gateway_lifecycle.go, gateway_tools_wiring.go for better maintainability
+- **SSE extraction**: Created shared SSEScanner in `providers/sse_reader.go` — unified streaming implementation used by OpenAI, Codex, and Anthropic streaming providers, eliminating provider-level duplication
+- **UI cleanup**: Removed v2/v3 toggle from web UI settings since v3 is now the only execution path
+- **Build compatibility**: All builds (PostgreSQL standard + SQLite desktop) compile cleanly. Dual-DB store pattern enables seamless database backend switching
+
 ### Added
 
+#### Knowledge Vault UI/Backend Enhancements (2026-04-09)
+- **Doc type inference**: `vault_link` tool now infers document type from file path instead of hardcoding "note"
+- **Link type parameter**: `vault_link` accepts optional `link_type` param (wikilink or reference, default wikilink)
+- **Pagination support**: `/v1/vault/documents` and `/v1/agents/{id}/vault/documents` return `{documents: [...], total: N}` for pagination
+- **CountDocuments store method**: Added to VaultStore interface with PostgreSQL and SQLite implementations
+- **Frontend pagination UI**: Vault documents table shows 100 items per page with Previous/Next navigation, "Showing X-Y of Z" indicator
+- **Team filter dropdown**: Vault page has team selector alongside agent selector for multi-team document filtering
+- **Graph view upgrade**: Independent graph data fetching (limit 500) with KG-level features:
+  - Node click highlight + neighbor emphasis + dim non-neighbors
+  - Double-click opens document detail dialog
+  - Zoom controls (ZoomIn/ZoomOut buttons + percentage display)
+  - Node limit selector (100/200/300/500 by degree centrality)
+  - Link labels on highlighted links + directional particles
+  - Stats bar showing doc/link counts
+  - Fit-to-view button to auto-center graph
+  - Background click clears selection
+  - Works in all-agents mode (shows nodes without agent-specific links)
+- **VaultDocument type updates**: Added team_id, summary, custom_scope, media type fields for richer metadata
+- **Files modified**:
+  - `internal/tools/vault_link.go` — doc type inference + link_type param
+  - `internal/http/vault_handlers.go` — pagination response wrapper
+  - `internal/store/vault_store.go`, `pg/vault_documents.go`, `sqlitestore/vault_documents.go` — CountDocuments
+  - `ui/web/src/pages/vault/*` — pagination, team filter, graph upgrade
+  - `ui/web/src/adapters/vault-graph-adapter.ts` — degree centrality limiting
+  - `ui/web/src/i18n/locales/{en,vi,zh}/*` — pagination + vault strings
+
+#### Vault Enrich Worker — Auto Summary + Semantic Linking (2026-04-09)
+- **Async document enrichment**: EventBus-driven worker auto-summarizes new/updated vault documents via LLM
+- **Vector embeddings**: Document summaries automatically embedded and indexed for semantic search
+- **Auto-linking**: Vector similarity search (0.7 threshold, top-5 neighbors) auto-creates bidirectional vault links
+- **Efficient batching**: BatchQueue[T] batches documents by tenantID:agentID, bounded dedup map (10K cap) prevents memory leaks
+- **Provider independence**: Separate provider resolution from consolidation pipeline, reuses master tenant provider
+- **Dual-DB support**: PostgreSQL includes full embed+link workflow; SQLite (desktop) summarizes only (no vector ops)
+- **Files added**:
+  - `internal/vault/enrich_worker.go` — BatchQueue-driven worker with bounded dedup
+  - `internal/eventbus/event_types.go` — EventVaultDocUpserted event type
+  - Updated `internal/store/vault_store.go` with UpdateSummaryAndReembed, FindSimilarDocs methods
+  - Updated PostgreSQL and SQLite vault document stores
+
+
 #### WhatsApp Native Protocol Integration (2026-04-06)
 - **Direct protocol migration**: Replaced Node.js Baileys bridge with direct in-process WhatsApp connectivity
 - **Database auth persistence**: Auth state, device keys, and client metadata stored in PostgreSQL (standard) or SQLite (desktop)

+
+GoClaw v3 introduces new HTTP endpoints for agent evolution metrics, episodic memory, knowledge vault, and orchestration. These are documented separately in [22 — V3 HTTP Endpoints](22-v3-http-endpoints.md) to keep this document focused on the core REST API. V3 endpoints follow the same authentication, error handling, and header conventions as documented above.

-## 8. Cross-References
+## 8. Agent Evolution Metrics System (V3)
+
+V3 introduces automated agent improvement via metrics-driven suggestions. Agents track tool usage, retrieval performance, and user feedback to generate actionable evolution recommendations.
+
+### 8.1 Metrics Collection
+
+Metrics are recorded during agent execution and stored per-agent in the database. Three metric types:
+
+| Type | Description | Examples |
+|------|-------------|----------|
+| **tool** | Tool invocation performance | invocation_count, success_rate, failure_count, avg_duration_ms |
+| **retrieval** | Knowledge retrieval quality | recall_rate, precision, relevance_score, query_count |
+| **feedback** | User satisfaction signals | rating, sentiment, effectiveness_score |
+
+**Collection points:**
+- Tool execution: name, status (success/failure), duration recorded in agent loop
+- Retrieval queries: recall metrics computed from vector search results
+- User feedback: optional post-run feedback API or implicit signals (abort/rephrase patterns)
+
+Metrics aggregate over 7-day rolling windows for suggestion analysis.
+
+### 8.2 Suggestion Engine
+
+`SuggestionEngine` analyzes aggregated metrics and generates suggestions via pluggable rules.
+
+**Architecture:**
+
+```
+Metrics Aggregation (7-day window)
+    ↓
+Rule Evaluation (run daily/weekly)
+    ├─ LowRetrievalUsageRule
+    ├─ ToolFailureRule
+    └─ RepeatedToolRule
+    ↓
+Suggestion Creation (pending status)
+    ↓
+Admin Review → Approve/Reject/Rollback
+```
+
+**Suggestion Types:**
+
+| Type | Trigger | Recommendation | Parameters |
+|------|---------|-----------------|------------|
+| `low_retrieval_usage` | Avg recall < threshold for 7 days | Lower `retrieval_threshold` parameter | `{current_threshold, proposed_threshold, confidence}` |
+| `tool_failure` | Single tool failure rate > 20% | Review tool config or fallback | `{tool_name, failure_count, success_count}` |
+| `repeated_tool` | Tool called 5+ consecutive times without context change | Consider extracting as skill | `{tool_name, occurrence_count, pattern_score}` |
+
+**Duplicate Prevention:** Only one pending suggestion per type per agent. New analyses skip rules that already have pending suggestions.
+
+### 8.3 Auto-Adapt Guardrails
+
+Suggestions can be auto-applied with safety constraints (optional admin-enabled). Guardrails prevent runaway adaptation.
+
+**Constraints:**
+
+| Name | Default | Purpose |
+|------|---------|---------|
+| `max_delta_per_cycle` | 0.1 | Max parameter change per apply cycle (prevents aggressive swings) |
+| `min_data_points` | 100 | Minimum metrics before applying (avoid overfitting on small sample) |
+| `rollback_on_drop_pct` | 20.0 | Auto-rollback if quality metric drops >20% after apply |
+| `locked_params` | `[]` | Parameters that cannot be auto-changed (e.g., security settings) |
+
+**Apply Flow:**
+
+1. Admin approves `low_retrieval_usage` suggestion (raises `retrieval_threshold` by +0.05)
+2. System checks: min_data_points met? parameter not locked? delta ≤ 0.1? → OK
+3. Baseline values saved for rollback
+4. Suggestion status → `applied`
+5. Monitor: if recall drops >20%, auto-rollback and set status → `rolled_back`
+
+**Baseline Storage:**
+
+Previous parameter values stored in suggestion `parameters._baseline` for rollback:
+
+```json
+{
+  "current_threshold": 0.5,
+  "proposed_threshold": 0.55,
+  "_baseline": {
+    "retrieval_threshold": 0.5
+  }
+}
+```
+
+### 8.4 Cron Scheduling
+
+Evolution analysis runs as a periodic cron job (default: daily).
+
+**Schedule:** Configurable via `evolution_cron_schedule` in agent config. Examples: `every day at 02:00`, `every 7 days at sunday 02:00`.
+
+**Execution:**
+1. Load all agents in tenant
+2. For each agent: `engine.Analyze(ctx, agentID)`
+3. Create pending suggestions (if new findings detected)
+4. Log results: created suggestions count, skipped rules, errors
+
+**Cron Event:** `evolution.analysis.completed` event emitted on completion.
+
+### 8.5 API & WebSocket
+
+**HTTP Endpoints** (see [22 — V3 HTTP Endpoints](22-v3-http-endpoints.md)):
+- `GET /v1/agents/{agentID}/evolution/metrics` — Query/aggregate metrics
+- `GET /v1/agents/{agentID}/evolution/suggestions` — List suggestions
+- `PATCH /v1/agents/{agentID}/evolution/suggestions/{suggestionID}` — Approve/reject/rollback
+
+**WebSocket Methods** (see [19 — WebSocket RPC](19-websocket-rpc.md)):
+- `agent.evolution.metrics` — Get metrics
+- `agent.evolution.suggestions` — List suggestions
+- `agent.evolution.apply` — Apply suggestion
+- `agent.evolution.rollback` — Rollback applied suggestion
+
+### 8.6 Configuration
+
+Per-agent evolution settings stored in `agents.other_config` JSONB:
+
+```json
+{
+  "evolution_enabled": true,
+  "evolution_guardrails": {
+    "max_delta_per_cycle": 0.1,
+    "min_data_points": 100,
+    "rollback_on_drop_pct": 20.0,
+    "locked_params": ["security_level"]
+  }
+}
+```
+
+Defaults used if keys absent. Set `evolution_enabled: false` to disable metrics collection entirely.

+The Knowledge Vault is a query layer above existing memory systems (episodic memory, knowledge graph, memory files). It provides document registration, bidirectional wikilinks, filesystem sync, and unified search across all knowledge sources.
+
+**Not a replacement** — extends capability. The vault sits between agents and episodic/KG stores, enabling agents to curate workspace documents with explicit relationships.
+
+---
+
+## 1. Architecture Overview
+
+### Components
+
+| Component | Role |
+|-----------|------|
+| **VaultStore** | Interface: document CRUD, link management, hybrid search (FTS+vector) |
+| **VaultService** | Search coordinator: fan-out across vault, episodic, KG; parallel queries with weighted ranking |
+| **VaultSyncWorker** | Filesystem watcher: detects file changes (create/write/delete), syncs content hashes back to registry |
+| **VaultRetriever** | Retrieval adapter: bridges vault search into agent L0 memory system |
+| **HTTP Handlers** | REST endpoints: list, get, search, links |
+
+### Data Flow
+
+```
+Agent writes document → Workspace FS
+                    ↓
+              VaultSyncWorker detects change
+                    ↓
+         Update vault_documents (hash, metadata)
+                    ↓
+         On agent query: vault_search tool
+                    ↓
+    VaultSearchService (parallel fan-out)
+         ↙        ↓        ↘
+    Vault    Episodic    Knowledge Graph
+         ↘        ↓        ↙
+      Normalize & Weight Scores
+         ↓
+   Return Top Results
+```
+
+### Tenant & Scope Isolation
+
+Documents are scoped by **tenant** (isolation), **agent** (per-agent namespace), and **document scope** (personal/team/shared):
+
+- **personal**: Agent-specific documents (agent_context_files, per-user work)
+- **team**: Team workspace documents (team_context_files)
+- **shared**: Cross-tenant shared knowledge (future)
+
+---
+
+## 2. Data Model
+
+### vault_documents
+
+Document registry: metadata pointers. Content lives on filesystem; registry holds path, hash, embeddings, and links.
+
+| Column | Type | Notes |
+|--------|------|-------|
+| `id` | UUID | Primary key |
+| `tenant_id` | UUID | Multi-tenant isolation |
+| `agent_id` | UUID | Per-agent namespace |
+| `scope` | TEXT | personal \| team \| shared |
+| `path` | TEXT | Workspace-relative path (workspace/notes/foo.md) |
+| `title` | TEXT | Display name |
+| `doc_type` | TEXT | context, memory, note, skill, episodic |
+| `content_hash` | TEXT | SHA-256 of file content (detects changes) |
+| `embedding` | vector(1536) | pgvector: semantic similarity |
+| `tsv` | tsvector | Generated: FTS index on title+path |
+| `metadata` | JSONB | Optional custom fields |
+| `created_at`, `updated_at` | TIMESTAMPTZ | Timestamps |
+| **Unique constraint** | (agent_id, scope, path) | One doc per path per scope |
+
+**Indices:**
+- `idx_vault_docs_tenant` — tenant_id (multi-tenant queries)
+- `idx_vault_docs_agent_scope` — agent_id, scope (agent-scoped filters)
+- `idx_vault_docs_type` — agent_id, doc_type (type filters)
+- `idx_vault_docs_hash` — content_hash (change detection)
+- `idx_vault_docs_embedding` — HNSW vector (semantic search)
+- `idx_vault_docs_tsv` — GIN FTS index (keyword search)
+
+### vault_links
+
+Bidirectional links between documents (wikilinks, explicit references).
+
+| Column | Type | Notes |
+|--------|------|-------|
+| `id` | UUID | Primary key |
+| `from_doc_id` | UUID | Source document |
+| `to_doc_id` | UUID | Target document |
+| `link_type` | TEXT | wikilink, reference, etc. |
+| `context` | TEXT | ~50 chars: surrounding text snippet |
+| `created_at` | TIMESTAMPTZ | Creation timestamp |
+| **Unique constraint** | (from_doc_id, to_doc_id, link_type) | No duplicate links |
+
+**Indices:**
+- `idx_vault_links_from` — from_doc_id (outgoing links)
+- `idx_vault_links_to` — to_doc_id (backlinks)
+
+### vault_versions
+
+Version history (v3.1+ preparation; empty in v3.0).
+
+| Column | Type | Notes |
+|--------|------|-------|
+| `id` | UUID | Primary key |
+| `doc_id` | UUID | Document reference |
+| `version` | INT | Version number |
+| `content` | TEXT | Snapshot of document content |
+| `changed_by` | TEXT | User/agent identifier |
+| `created_at` | TIMESTAMPTZ | Snapshot timestamp |
+
+---
+
+## 3. Wikilinks
+
+Bidirectional markdown links in the `[[target]]` format.
+
+### Parsing & Extraction
+
+`ExtractWikilinks(content string)` parses all `[[...]]` patterns:
+
+- **Format:** `[[path/to/file.md]]` or `[[name|display text]]` (display text ignored)
+- **Returns:** `[]WikilinkMatch` with target, context (~50 chars), and byte offset
+
+Examples:
+```markdown
+See [[architecture/components]] for details.
+Reference [[SOUL.md|agent persona]] here.
+Link [[../parent-project]] up.
+```
+
+**Edge cases:**
+- Empty target `[[]]` → skipped
+- Whitespace-only targets → trimmed and skipped
+- Paths with spaces: `[[foo bar]]` → preserved
+- File extensions: `.md` auto-appended if missing
+
+### Resolution Strategy
+
+`ResolveWikilinkTarget()` finds the document matching a wikilink target:
+
+1. **Exact path match** — `GetDocument(tenantID, agentID, "path/to/file.md")`
+2. **With .md suffix** — If target lacks `.md`, retry with suffix
+3. **Basename search** — Linear search through all agent docs; match by basename (case-insensitive)
+4. **Unresolved** — Return nil (not an error; backlinks can be incomplete)
+
+Example: `[[SOUL.md]]` → lookup SOUL.md → fallback to lookup SOUL → scan for any doc with basename SOUL
+
+### Link Sync
+
+`SyncDocLinks(ctx, vaultStore, doc, content, tenantID, agentID)` keeps wikilinks in vault_links in sync with document content:
+
+1. Extract `[[...]]` patterns from content
+2. Delete all outgoing links for the document (replace strategy)
+3. For each match:
+   - Resolve target via strategy above
+   - Create `vault_link` row if resolved
+4. Return (errors logged, not thrown)
+
+Called during:
+- Document upsert (agent writing to workspace)
+- VaultSyncWorker processing file changes
+
+---
+
+## 4. Search
+
+Hybrid search integrates vault FTS, vector embeddings, episodic memory, and knowledge graph.
+
+### Vault Search (Store-Level)
+
+`VaultStore.Search(ctx, opts VaultSearchOptions)` on single vault:
+
+- **FTS**: PostgreSQL `plainto_tsquery()` on tsv (title+path keywords)
+- **Vector**: pgvector cosine similarity on embedding (semantic)
+- **Combined scoring**: Normalize each method's scores (0–1), then apply query-time weights
+- **Results:** Top N documents with score
+
+### Unified Search (Cross-Store)
+
+`VaultSearchService.Search(ctx, opts UnifiedSearchOptions)`:
+
+**Parallel fan-out:**
+```
+Query → ├─ VaultStore.Search()      [0.4 weight]
+        ├─ EpisodicStore.Search()   [0.3 weight]
+        └─ KGStore.SearchEntities() [0.3 weight]
+                ↓
+         Normalize each source
+         (max score = 1.0, then * weight)
+                ↓
+         Merge & deduplicate by ID
+                ↓
+         Sort by final score DESC
+                ↓
+         Return top N
+```
+
+**Score normalization:** Each source's scores scaled to 0–1 (max_score / weight), then weighted:
+- Vault: 0.4 (keyword + semantic)
+- Episodic: 0.3 (session summaries)
+- KG: 0.3 (entity relationships)
+
+Default max results per source: `maxResults * 2` (then deduplicate + cap to maxResults).
+
+### Parameters
+
+| Param | Type | Default | Notes |
+|-------|------|---------|-------|
+| `Query` | string | — | Required: natural language |
+| `AgentID` | string | — | Scope to agent |
+| `TenantID` | string | — | Scope to tenant |
+| `Scope` | string | all | personal, team, shared |
+| `DocTypes` | []string | all | context, memory, note, skill, episodic |
+| `MaxResults` | int | 10 | Results per final result set |
+| `MinScore` | float64 | 0.0 | Filter by minimum score |
+
+---
+
+## 5. Filesystem Sync
+
+`VaultSyncWorker` watches workspace directories for changes and keeps vault_documents hashes in sync.
+
+### Watcher Loop
+
+Uses `fsnotify` to detect Write, Create, Remove events:
+
+1. Debounce: 500ms (multiple rapid changes → one batch)
+2. For each file change:
+   - Compute SHA-256 hash of file content
+   - Compare to `vault_documents.content_hash`
+   - If different: update hash in DB
+   - If file deleted: mark `metadata["deleted"] = true`
+
+### Constraints
+
+- Only syncs **registered** documents (files already in vault_documents)
+- New files must be registered by agent (via agent write) first
+- Unreadable files → marked as deleted
+
+### Setup
+
+```go
+syncer := vault.NewVaultSyncWorker(vaultStore)
+go syncer.Watch(ctx, workspaceDir, tenantID, agentID)
+```
+
+---
+
+## 6. HTTP API
+
+RESTful endpoints for vault operations.
+
+### List Documents
+
+**Endpoint:** `GET /v1/agents/{agentID}/vault/documents`

+}
+```
+
+### List (Cross-Agent)
+
+**Endpoint:** `GET /v1/vault/documents`
+
+**Query params:**
+- `agent_id` — optional filter to specific agent (otherwise all tenant agents)
+- `scope`, `doc_type`, `limit`, `offset` — same as per-agent endpoint
+
+---
+
+## 7. Tools
+
+Agents access vault via two tools.
+
+### vault_search
+
+**Primary discovery tool:** Search across all knowledge sources (vault, episodic, KG) with unified ranking.
+
+**Parameters:**
+```json
+{
+  "query": "string (required)",
+  "scope": "string (optional: personal|team|shared)",
+  "types": "string (optional: comma-separated doc types)",
+  "maxResults": "number (optional: default 10)"
+}
+```
+
+**Example:**
+```
+Agent: "Find documents about authentication"
+Tool call: vault_search(query="authentication", types="context,note")
+Result: Top 10 results from vault + episodic + KG
+```
+
+### vault_link
+
+**Create explicit link:** Connect two documents (similar to [[wikilink]]).
+
+**Parameters:**
+```json
+{
+  "from": "string (source document path, required)",
+  "to": "string (target document path, required)",
+  "context": "string (optional: relationship description)"
+}
+```
+
+**Example:**
+```
+Agent: "Link the authentication guide to the SOUL file"
+Tool call: vault_link(from="docs/auth.md", to="SOUL.md", context="Persona reference")
+Result: Explicit link created in vault_links
+```
+
+---
+
+## 8. Retriever Integration
+
+`VaultRetriever` bridges vault search into agent L0 memory system.
+
+### Usage
+
+```go
+retriever := vault.NewVaultRetriever(searchService)
+summaries, err := retriever.RetrieveL0(ctx, agentID, userID, query, config)
+// Returns []memory.L0Summary with highest-ranked results
+```
+
+### Configuration
+
+```go
+type RetrieverConfig struct {
+  RelevanceThreshold float64  // default 0.3
+  MaxL0Items         int      // default 5
+  TenantID           string
+}
+```
+
+Used by agent to retrieve relevant documents during think phase (before plan/act).
+
+---
+
+## 9. Web UI (v3)
+
+Vault page in dashboard displays:
+
+- **Document list** — workspace documents filtered by scope/type
+- **Graph visualization** — nodes = documents, edges = wikilinks, interactive pan/zoom
+- **Search interface** — unified cross-store search with source badges
+- **Link editor** — create/remove links between documents
+
+---
+
+## 10. Feature Flags & Configuration
+
+Knowledge Vault is **v3-only** feature.
+
+- **Edition:** Standard and Lite (full support)
+- **Prerequisite:** PostgreSQL with pgvector extension
+- **Storage:** vault_* tables created by migration 000038
+- **Workspace:** Documents organized in agent-level workspace directory (e.g., `~/.goclaw/workspace/agent_name/`)
+
+No explicit feature flag; vault is enabled if:
+1. Migration 000038 ran successfully
+2. VaultStore initialized during gateway startup
+3. VaultSyncWorker started
+
+---
+
+## 11. Examples
+
+### Adding a Document
+
+Agent writes to workspace:
+```
+~/.goclaw/workspace/myagent/notes/architecture.md
+```
+
+On next sync (or immediate write):
+1. VaultSyncWorker detects file creation
+2. Computes SHA-256 hash
+3. Vault document auto-registered with metadata
+
+### Creating a Wikilink
+
+Markdown content:
+```markdown
+See [[architecture.md]] for system design.
+See [[SOUL.md|persona]] for agent personality.
+```
+
+Agent calls `vault_search("system design")`:
+1. ExtractWikilinks finds `[[architecture.md]]` and `[[SOUL.md]]`
+2. ResolveWikilinkTarget matches to registered documents
+3. SyncDocLinks creates vault_link rows
+4. Backlinks available via `/links` endpoint
+
+### Search Example
+
+Agent: "Find notes about authentication"
+
+Request:
+```json
+POST /v1/agents/agent-123/vault/search
+{
+  "query": "authentication flow",
+  "scope": "personal",
+  "max_results": 5
+}
+```
+
+Response (parallel results from vault + episodic + KG):
+```json
+[
+  {
+    "document": {
+      "id": "doc-456",
+      "path": "notes/auth.md",
+      "title": "Authentication Flow",
+      "doc_type": "note"
+    },
+    "score": 0.92,
+    "source": "vault"
+  },
+  {
+    "id": "episodic-789",
+    "title": "Session-2026-04-06",
+    "source": "episodic",
+    "score": 0.68
+  }
+]
+```
+
+---
+
+## 12. Limitations
+
+- **Vault docs do not auto-embed in system prompt** — Must be retrieved via agent tools
+- **No full-text indexing on document content** — Only title+path FTS; content requires embeddings
+- **Sync is one-way** — Filesystem changes sync to vault; vault does not write back to FS
+- **No conflict resolution** — Concurrent edits not detected; last write wins
+- **Version history empty** — vault_versions table prepared for v3.1
+

+## 6. Model Registry (v3)
+
+The **model registry** (v3) provides structured metadata about LLM models used by the steering system and cost calculation:
+
+```
+ModelRegistry interface
+├── Resolve(provider, modelID) → ModelSpec
+├── Register(spec ModelSpec)
+├── Catalog(provider) → []ModelSpec
+└── RegisterResolver(provider, ForwardCompatResolver)
+```
+
+Each `ModelSpec` includes:
+- **ID, Provider**: Model identifier
+- **ContextWindow, MaxTokens**: Capacity bounds
+- **Reasoning, Vision**: Capability flags
+- **TokenizerID**: For token estimation
+- **Cost**: Per-1M-token pricing (input, output, cache-read)
+
+**Forward-compatibility resolver** — providers can implement custom resolution for unknown models, allowing dynamic pricing updates without code changes. The registry caches resolved specs for performance.
+
+**Model steering uses the registry for:**
+- Context window checks (adaptive throttle at 60%)
+- Token-based iteration budgets and hints (75%, 90% warnings)
+- Cost calculation in traces

+- If a system message reports completed work, rewrite in your normal voice and send. Don't forward raw system text.

+
+## Memory
+
+- **Recall:** Use `memory_search` before answering about prior work, decisions, or preferences
+- **Save:** Use `write_file` to persist important information:
+  - Daily notes → `memory/YYYY-MM-DD.md`
+  - Long-term → `MEMORY.md` (curated: key decisions, lessons, significant events)
+- **No "mental notes"** — if you want to remember something, write it to a file NOW
+- **Recall details:** Use `memory_search` first, then `memory_get` to pull only needed lines.
+  If `knowledge_graph_search` is available, also run it for multi-hop relationships.
+
+### MEMORY.md Privacy
+
+- Only reference MEMORY.md content in **private/direct chats** with your user
+- In group chats or shared sessions, do NOT surface personal memory content
+
+## Scheduling
+
+Use the `cron` tool for periodic or timed tasks.
+- Keep messages specific and actionable
+- Use `kind: "at"` for one-shot reminders (auto-deletes after running)
+- Use `deliver: true` with `channel` and `to` to send output to a chat
+- Don't create too many frequent jobs — batch related checks

+## Known Info
+
+If user info is provided in the system prompt above (from the chat platform), use it directly.
+Confirm their name and timezone briefly — don't re-ask what you already know.
+Only ask for info you DON'T already have. This should be a 1-turn onboarding, not 3-5 turns.

+# Phase 1: Foundation Interfaces
+
+## Context Links
+
+- Brainstorm: `plans/reports/brainstorm-260406-1059-goclaw-v3-core-redesign.md` (decisions 5, 8, 14, 10)
+- Architecture: `plans/reports/Explore-260406-thorough-v3-architecture.md` (sections 1, 2, 6, 7)
+- Loop deep dive: `plans/reports/Explore-260406-GoClaw-Agent-Loop-v3-Deep-Dive.md` (section 2, 3)
+- Workspace forcing: `plans/reports/Explore-260406-workspace-forcing.md`
+
+## Overview
+
+- **Priority:** P1 (all other phases depend on these)
+- **Status:** Complete
+- **Effort:** 8h design
+
+4 foundational components with zero cross-dependencies. Can be designed and implemented in parallel. Every subsequent phase (pipeline, memory, integration) depends on at least one of these.
+
+## Key Insights
+
+- Token counting currently `chars/4` estimate -- drives ALL compaction/pruning decisions. Replacing with tiktoken-go is highest-ROI change
+- Workspace resolution has 5 identified confusion sources (see workspace forcing report). Single immutable WorkspaceContext eliminates dual-key confusion
+- EventBus currently `map[string]any` payloads, string topic constants. V3 needs typed events for consolidation pipeline
+- Provider interface (`providers.Provider`) is functional but loop handles provider quirks directly. Adapter pattern isolates quirks
+
+---
+
+## A. TokenCounter Interface
+
+### Interface Contract
+
+```go
+// Package: internal/tokencount
+
+// TokenCounter provides accurate per-model token counting.
+// Replaces chars/4 estimation used in compaction + pruning.
+type TokenCounter interface {
+    // Count returns token count for raw text using model's tokenizer.
+    Count(model string, text string) int
+
+    // CountMessages returns token count for a message list,
+    // including per-message overhead (role tokens, separators).
+    CountMessages(model string, msgs []providers.Message) int
+
+    // ModelContextWindow returns max context tokens for a model.

+    "deepseek-":      {TokenizerCL100K, 128_000}, // approx
+}
+```
+
+### Caching Strategy
+
+```go
+// cachedCounter wraps a tokenizer with per-message hash cache.
+// Key: SHA-256(model + role + content + tool_call_ids)
+// Value: token count (int)
+// Eviction: LRU, 10K entries (typical session < 500 messages)
+type cachedCounter struct {
+    cache *lru.Cache[string, int] // hashicorp/golang-lru/v2
+    mu    sync.RWMutex
+}
+```
+
+Cache avoids re-counting unchanged messages during mid-loop re-estimation. Only new/modified messages hit tokenizer.
+
+### Per-Message Overhead
+
+```
+Per message: +4 tokens (role marker + separators)
+System message: +4 tokens additional
+Tool calls: name + JSON args counted as text
+Tool results: content text counted
+Images: model-specific (Claude: tile-based, GPT: similar)
+```
+
+### Data Flow
+
+```
+Pipeline stage needs token count
+  -> TokenCounter.CountMessages(model, messages)
+     -> For each message:
+        -> Hash(model, msg) -> check cache
+        -> Cache miss: tokenizer.Encode(text) -> count -> store
+     -> Sum + per-message overhead
+     -> Return total
+```

+
+6. Group chat:

+### Affected Files
+
+| File | What changes |
+|------|-------------|
+| `internal/agent/loop_context.go:110-176` | Replace workspace resolution with `Resolver.Resolve()` |
+| `internal/tools/context_keys.go` | Remove `ctxWorkspace`, `ctxTeamWorkspace`, `effectiveRestrict()` |

+### Breaking Changes
+
+- `ctxWorkspace` / `ctxTeamWorkspace` context keys removed

+- `WithToolWorkspace()` / `WithToolTeamWorkspace()` replaced by single `WithWorkspaceContext()`
+- `tools.WithRestrictToWorkspace()` removed (enforcement = default)

+
+## C. EventBus Redesign
+
+### Interface Contract
+
+```go
+// Package: internal/eventbus (new package, replaces internal/bus for domain events)
+// Note: internal/bus MessageBus retained for channel message routing (InboundMessage/OutboundMessage).
+
+// DomainEvent is a typed event with metadata for consolidation pipeline.

+    ID        string    // UUID v7 for ordering

+    TenantID  string
+    AgentID   string
+    UserID    string
+    Timestamp time.Time
+    Payload   any       // typed per EventType (see below)
+}
+
+// EventType identifies the event category.
+type EventType string
+
+const (
+    EventSessionCompleted EventType = "session.completed"
+    EventEpisodicCreated  EventType = "episodic.created"
+    EventEntityUpserted   EventType = "entity.upserted"
+    EventMemoryLint       EventType = "memory.lint"
+    EventRunCompleted     EventType = "run.completed"
+    EventToolExecuted     EventType = "tool.executed"
+)
+
+// Typed payloads -- one per EventType.
+
+type SessionCompletedPayload struct {
+    SessionKey   string
+    MessageCount int
+    TokensUsed   int
+    Summary      string // compaction summary if available
+}
+
+type EpisodicCreatedPayload struct {
+    EpisodicID  string
+    SessionKey  string
+    Summary     string
+    KeyEntities []string // entity names for downstream extraction
+}
+
+type EntityUpsertedPayload struct {
+    EntityIDs []string // newly upserted entity UUIDs
+}
+
+type MemoryLintPayload struct {
+    Scope string // "agent" or "user"
+}
+
+type RunCompletedPayload struct {
+    RunID      string
+    Iterations int
+    TokensUsed int
+    ToolCalls  int
+    LoopKilled bool
+}
+
+type ToolExecutedPayload struct {
+    ToolName  string
+    Duration  time.Duration
+    Success   bool
+    ReadOnly  bool
+}
+
+// DomainEventBus manages typed event publishing + worker subscriptions.
+type DomainEventBus interface {
+    // Publish enqueues an event for async processing.
+    // Non-blocking: returns immediately.
+    Publish(event DomainEvent)
+
+    // Subscribe registers a worker for a specific event type.
+    // handler called in worker pool goroutine.
+    // Returns unsubscribe function.
+    Subscribe(eventType EventType, handler DomainEventHandler) func()
+
+    // Start launches worker pool. Must be called before Publish.
+    Start(ctx context.Context)
+
+    // Drain waits for all queued events to be processed. For graceful shutdown.
+    Drain(timeout time.Duration) error
+}
+
+type DomainEventHandler func(ctx context.Context, event DomainEvent) error
+```
+
+### Worker Pool Design
+
+```go
+// Config for the domain event bus.
+type Config struct {
+    QueueSize     int           // buffered channel capacity (default 1000)
+    WorkerCount   int           // goroutines per event type (default 2)
+    RetryAttempts int           // retry on handler error (default 3)
+    RetryDelay    time.Duration // backoff base (default 1s, exponential)
+}
+```
+
+Lane-based concurrency: each EventType gets its own worker pool. Events of different types processed in parallel. Events of same type processed sequentially per-worker (but multiple workers can process different events of same type concurrently).
+
+### Idempotency
+
+Dedup by `SourceID`: events with same SourceID + EventType processed at most once. Implementation: in-memory set with TTL (1h). If event bus restarts, re-processing is safe because all handlers are idempotent.
+
+```go
+// dedup check before handler dispatch
+func (b *bus) dispatch(event DomainEvent) {
+    key := event.Type + ":" + event.SourceID
+    if b.seen.Has(key) {
+        return // already processed
+    }
+    b.seen.Set(key, time.Now().Add(b.dedupTTL))
+    // dispatch to handler...
+}
+```
+
+### Integration Points
+
+| Producer | Event | Consumer |
+|----------|-------|----------|
+| Pipeline ObserveStage | `run.completed` | Metrics, tracing |
+| Pipeline ObserveStage | `tool.executed` | Self-evolution metrics |
+| Session close / compaction | `session.completed` | Episodic summary worker |
+| Episodic worker | `episodic.created` | Semantic extraction worker |
+| KG ingest | `entity.upserted` | Dedup check worker |
+| Cron scheduler | `memory.lint` | Memory lint worker |
+
+### Affected Files
+
+| File | What changes |
+|------|-------------|
+| `internal/bus/types.go` | Retained for channel routing. DomainEvent types in new package |
+| `internal/bus/bus.go` | Retained. New `internal/eventbus/` package alongside |
+| `internal/agent/loop_run.go` | Publish `run.completed` after finalize |
+| `internal/agent/loop_tools.go` | Publish `tool.executed` per tool call |
+| `internal/agent/loop_history.go:624-699` | Publish `session.completed` in `maybeSummarize()` |
+
+### Breaking Changes
+
+- None for existing `bus.MessageBus` (retained)
+- New `internal/eventbus` package added
+- Agent loop gains `DomainEventBus` dependency (injected via `Loop` struct)
+
+---
+
+## D. ProviderAdapter Interface
+
+### Interface Contract
+
+```go
+// Package: internal/providers (extends existing package)
+
+// ProviderCapabilities declares what a provider supports.
+// Queried by pipeline to choose code paths (streaming vs non-streaming, etc.)
+type ProviderCapabilities struct {
+    Streaming       bool   // supports ChatStream()
+    ToolCalling     bool   // supports tools in request
+    StreamWithTools bool   // can stream while tool calls are in-flight (false for DashScope)
+    Thinking        bool   // supports extended thinking / reasoning
+    Vision          bool   // supports image inputs
+    CacheControl    bool   // supports cache_control blocks (Anthropic)
+    MaxContextWindow int   // default context window for default model
+    TokenizerID     string // for tokencount package mapping
+}
+
+// ProviderAdapter transforms between internal wire format and provider-specific format.
+// Each provider implements this to isolate quirks from the pipeline loop.
+type ProviderAdapter interface {
+    // ToRequest converts internal ChatRequest to provider-specific wire bytes.
+    // Handles: schema transforms, thinking passback, cache control injection.
+    ToRequest(req ChatRequest) ([]byte, http.Header, error)
+
+    // FromResponse converts provider-specific response bytes to internal ChatResponse.
+    // Handles: thinking extraction, usage normalization, finish reason mapping.
+    FromResponse(data []byte) (*ChatResponse, error)
+
+    // FromStreamChunk converts a single SSE chunk to internal StreamChunk.
+    // Returns nil if chunk should be skipped (keep-alive, metadata).
+    FromStreamChunk(data []byte) (*StreamChunk, error)
+
+    // Capabilities returns static capability declaration.
+    Capabilities() ProviderCapabilities
+
+    // Name returns provider identifier.
+    Name() string
+}
+
+// CapabilitiesAware is optionally implemented by Provider.
+// Pipeline checks this to choose code path.
+type CapabilitiesAware interface {
+    Capabilities() ProviderCapabilities
+}
+```
+
+### Adapter Registry
+
+```go
+// AdapterRegistry maps provider names to adapter factories.
+// Enables plugin-style provider registration.
+type AdapterRegistry struct {
+    mu       sync.RWMutex
+    adapters map[string]AdapterFactory
+}
+
+type AdapterFactory func(cfg ProviderConfig) (ProviderAdapter, error)
+
+// Register adds a provider adapter. Called at init() or runtime.
+func (r *AdapterRegistry) Register(name string, factory AdapterFactory) {
+    r.mu.Lock()
+    defer r.mu.Unlock()
+    r.adapters[name] = factory
+}
+
+// Get returns adapter for provider name. Error if not registered.
+func (r *AdapterRegistry) Get(name string, cfg ProviderConfig) (ProviderAdapter, error) {
+    r.mu.RLock()
+    factory, ok := r.adapters[name]
+    r.mu.RUnlock()
+    if !ok {
+        return nil, fmt.Errorf("unknown provider: %s", name)
+    }
+    return factory(cfg)
+}
+```
+
+### What Moves to Adapter
+
+| Currently in loop/provider | Moves to adapter |
+|---------------------------|-----------------|
+| `RawAssistantContent` passback (Anthropic thinking blocks) | `AnthropicAdapter.ToRequest()` |
+| `ThinkingSignature` accumulation | `AnthropicAdapter.FromStreamChunk()` |
+| DashScope non-streaming fallback for tool calls | `DashScopeAdapter.Capabilities().StreamWithTools = false` |
+| Codex `Phase` field injection | `CodexAdapter.ToRequest()` / `FromResponse()` |
+| Schema normalization (tool definitions → provider format) | Each adapter's `ToRequest()` |
+| Usage normalization (different field names) | Each adapter's `FromResponse()` |
+
+### Pipeline Usage
+
+```
+ThinkStage:
+  1. caps := provider.Capabilities() // if CapabilitiesAware
+  2. If caps.StreamWithTools == false && len(tools) > 0:
+     -> use Chat() not ChatStream()
+  3. If caps.Thinking:
+     -> inject thinking options
+  4. Call Chat/ChatStream as before (Provider interface unchanged)
+  5. Provider internally uses its adapter for wire transforms
+```
+
+Important: `providers.Provider` interface UNCHANGED. `ProviderAdapter` is internal to each provider implementation. Pipeline queries capabilities via optional `CapabilitiesAware` interface on the provider.
+
+### Affected Files
+
+| File | What changes |
+|------|-------------|
+| `internal/providers/types.go` | Add `ProviderCapabilities`, `CapabilitiesAware` |
+| `internal/providers/anthropic.go` | Extract wire transforms to `AnthropicAdapter` |
+| `internal/providers/openai.go` | Extract wire transforms to `OpenAIAdapter` |
+| `internal/providers/dashscope.go` | `StreamWithTools = false` in capabilities |
+| `internal/providers/codex.go` | Phase handling in adapter |
+| `internal/agent/loop.go:217-323` | ThinkStage queries capabilities instead of provider-type checks |
+
+### Breaking Changes
+
+- `ThinkingCapable` interface superseded by `CapabilitiesAware` (backward compatible -- both can coexist during transition)
+- Provider-specific branching in loop.go removed (replaced by capability checks)
+- No external API changes
+
+---
+
+## Requirements
+
+### Functional
+- F1: Token counting accurate within 5% of provider-reported usage
+- F2: WorkspaceContext resolves all 6 scenarios correctly (solo DM, shared, team dispatch, team inbound, delegate, group)
+- F3: DomainEventBus processes events within 100ms p99 (in-process)
+- F4: Provider capabilities queryable without LLM call
+
+### Non-Functional
+- NF1: TokenCounter cache hit rate >90% in typical session (messages rarely change)
+- NF2: WorkspaceContext immutable after creation (no data races)
+- NF3: EventBus handles 1000 events/sec sustained (consolidation pipeline load)
+- NF4: All 4 components have zero cross-dependencies (can implement in parallel)
+
+## Design Steps
+
+1. Define `TokenCounter` interface + `ModelRegistry` mapping table
+2. Implement `cachedCounter` with tiktoken-go + LRU cache
+3. Define `WorkspaceContext` struct + `Resolver` interface
+4. Implement resolver with resolution rules table
+5. Define `DomainEvent` types + `DomainEventBus` interface
+6. Implement worker pool with lane-based concurrency + dedup
+7. Define `ProviderCapabilities` + `CapabilitiesAware` interface
+8. Define `AdapterRegistry` for plugin registration
+
+## Todo List
+
+- [x] A1: TokenCounter interface definition — `internal/tokencount/token_counter.go`
+- [x] A2: ModelRegistry with prefix-based mapping — `internal/tokencount/token_counter.go`
+- [x] A3: Per-message hash cache design — documented in phase, cache impl deferred to implementation
+- [x] A4: Fallback strategy for unknown models — `internal/tokencount/fallback_counter.go`
+- [x] B1: WorkspaceContext struct definition — `internal/workspace/workspace_context.go`
+- [x] B2: Resolver interface + ResolveParams — `internal/workspace/workspace_context.go`
+- [x] B3: Resolution rules for all 6 scenarios — documented in phase design
+- [x] B4: System prompt template section for workspace — documented in phase design
+- [x] B5: Enforcement label design — EnforcementLabel field in WorkspaceContext
+- [x] C1: DomainEvent type definitions — `internal/eventbus/event_types.go`
+- [x] C2: Typed payload structs for each event — `internal/eventbus/event_types.go`
+- [x] C3: DomainEventBus interface — `internal/eventbus/domain_event_bus.go`
+- [x] C4: Worker pool config + lane-based concurrency design — `internal/eventbus/domain_event_bus.go`
+- [x] C5: Idempotency / dedup strategy — documented in phase design (SourceID-based)
+- [x] D1: ProviderCapabilities struct — `internal/providers/capabilities.go`
+- [x] D2: CapabilitiesAware optional interface — `internal/providers/capabilities.go`
+- [x] D3: AdapterRegistry for plugin registration — `internal/providers/adapter_registry.go`
+- [x] D4: Document what moves from loop to each adapter — documented in phase design
+
+## Success Criteria
+
+- All 4 interfaces defined with complete method signatures
+- Each interface has zero imports from the other 3
+- WorkspaceContext resolution rules cover all 6 scenarios
+- Token counting accuracy validated against Anthropic/OpenAI reported usage
+- EventBus worker pool supports lane-based concurrency with configurable workers
+- Provider capabilities capture all known provider quirks (DashScope, Codex, Anthropic)
+
+## Risk Assessment
+
+| Risk | Severity | Mitigation |
+|------|----------|------------|
+| tiktoken-go tokenizer not exact match for Claude models | MEDIUM | Claude uses custom tokenizer, cl100k_base is approximation. Validate against API usage. Accept 5% error. |
+| WorkspaceContext missing edge case for new workspace scenario | LOW | Resolution rules table is explicit. Add new row when new scenario appears. |
+| EventBus in-process limitation (single instance, no persistence) | LOW | Sufficient for v3.0. External bus (Redis streams) can implement same interface later. |
+| ProviderAdapter abstraction leaks (provider needs loop context) | MEDIUM | Keep adapter stateless. Pass all needed data via `ChatRequest` fields. |
+
+## Security Considerations
+
+- WorkspaceContext enforcement is security-critical: `ActivePath` must be validated (no path traversal)
+- Existing `resolvePath()` security (symlink, hardlink checks) preserved -- WorkspaceContext provides the boundary, not the validation
+- EventBus handlers must not leak tenant data across boundaries (TenantID in every event)
+- TokenCounter is read-only, no security concerns
+
+## Next Steps
+
+- Phase 2 (Pipeline Loop) consumes all 4 interfaces
+- Phase 3 (Memory & KG) consumes TokenCounter + DomainEventBus
+- Phase 4 (System Integration) consumes WorkspaceContext + ProviderCapabilities

+# Phase 2: Pipeline Loop Design
+
+## Context Links
+
+- Brainstorm: `plans/reports/brainstorm-260406-1059-goclaw-v3-core-redesign.md` (decision 1)
+- Loop deep dive: `plans/reports/Explore-260406-GoClaw-Agent-Loop-v3-Deep-Dive.md` (all sections)
+- Phase 1 dependencies: `phase-01-foundation-interfaces.md` (TokenCounter, WorkspaceContext, EventBus, ProviderCapabilities)
+- Current loop: `internal/agent/loop.go` (804 lines), `loop_types.go`, `loop_context.go`, `loop_history.go`, `loop_compact.go`, `pruning.go`, `loop_tools.go`, `loop_run.go`
+
+## Overview
+
+- **Priority:** P1 (core execution engine, blocks phases 3-6)
+- **Status:** Complete
+- **Effort:** 8h design
+- **Depends on:** Phase 1 (all 4 foundation interfaces)
+
+Replace monolithic `runLoop()` (804 lines, 20+ field `runState`) with a pipeline of pluggable stages. Each stage owns a substage of state, is independently testable, and communicates via a shared `RunState` struct.
+
+## Key Insights
+
+- Current loop has 7 exit conditions scattered across 800 lines. Pipeline model makes each exit condition a stage responsibility.
+- `runState` has 20+ fields mixing concerns (loop control, output accumulation, crash safety, bootstrap detection, team task tracking, skill evolution). Split into typed substates.
+- Mid-loop compaction (lines 352-411) interleaves with think phase. Pipeline separates this into `PruneStage` between think and tool.
+- Parallel tool execution already well-isolated (goroutine per tool, results collected via channel). Wrapping in `ToolStage` is clean.
+- Memory flush currently triggers inside `maybeSummarize()` which runs post-loop. Moving to `MemoryFlushStage` pre-compaction aligns with 3-tier memory design.

+
+## A. Stage Interface
+
+```go
+// Package: internal/pipeline
+
+// Stage is a single step in the agent pipeline.
+// Stages are stateless -- all mutable state lives in RunState.
+type Stage interface {
+    // Name returns a human-readable identifier for logging/tracing.
+    Name() string
+
+    // Execute performs the stage's work. Returns error to abort pipeline.
+    // Stages modify RunState in place.
+    Execute(ctx context.Context, state *RunState) error
+}
+
+// StageResult signals how the pipeline should proceed after a stage.
+type StageResult int
+
+const (
+    Continue    StageResult = iota // proceed to next stage
+    BreakLoop                      // exit iteration loop (normal completion)
+    AbortRun                       // abort entire run (error/kill)
+)
+
+// StageWithResult extends Stage to control pipeline flow.
+// If a stage does not implement this, pipeline assumes Continue.
+type StageWithResult interface {
+    Stage
+    Result() StageResult
+}
+```
+
+## B. RunState Redesign
+
+Split current 20+ field `runState` into typed substates. Each substate grouped by owning stage.
+
+```go
+// RunState is the shared mutable state for a single pipeline run.
+// Passed by pointer through all stages.
+type RunState struct {
+    // Identity (set once at pipeline start, immutable during run)
+    Request   *agent.RunRequest
+    Workspace *workspace.WorkspaceContext
+    Model     string
+    Provider  providers.Provider
+
+    // Message buffer (read/write by multiple stages)
+    Messages  *MessageBuffer
+
+    // Per-stage substates
+    Context   ContextState
+    Think     ThinkState
+    Prune     PruneState
+    Tool      ToolState
+    Observe   ObserveState
+    Compact   CompactState
+    Evolution EvolutionState
+
+    // Cross-cutting concerns
+    Iteration int
+    RunID     string
+    ExitCode  StageResult
+}
+
+// MessageBuffer wraps the message list with append/replace semantics.
+// Thread-safe for read; write only from owning stage (sequential pipeline).
+type MessageBuffer struct {
+    system   providers.Message   // system prompt (rebuilt by ContextStage)
+    history  []providers.Message // conversation history
+    pending  []providers.Message // new messages this run (flushed at checkpoint)
+}
+
+func (mb *MessageBuffer) All() []providers.Message { /* system + history + pending */ }
+func (mb *MessageBuffer) AppendPending(msg providers.Message) { /* ... */ }
+func (mb *MessageBuffer) FlushPending() []providers.Message { /* move pending to history */ }
+func (mb *MessageBuffer) ReplaceHistory(msgs []providers.Message) { /* post-compaction */ }
+```
+
+### Substates
+
+```go
+// ContextState: owned by ContextStage, read by ThinkStage
+type ContextState struct {
+    ContextFiles  []bootstrap.ContextFile
+    SkillsSummary string
+    TeamContext   *TeamContextInfo // nil if not in team

+## C. Stage Catalog
+
+### Setup Pipeline (runs once before iteration loop)
+
+```
+1. ContextStage
+   - Resolve WorkspaceContext via Resolver
+   - Load + filter context files (bootstrap, per-user, team)
+   - Build skills summary (BM25)
+   - Build system prompt via template
+   - Compute overhead tokens (TokenCounter)
+   - Enrich input media
+   - Inject team task reminders
+   
+   Reads: RunState.Request, providers
+   Writes: RunState.Workspace, ContextState, MessageBuffer.system
+   
+   Replaces: injectContext() + buildMessages() + enrichInputMedia() + injectTeamTaskReminders()
+```
+
+### Iteration Pipeline (runs per iteration, max N times)
+
+```
+2. ThinkStage
+   - Inject iteration budget nudges (70%, 90%)
+   - Build per-iteration tool definitions (policy + bootstrap filters)
+   - Build ChatRequest from MessageBuffer
+   - Call LLM (Chat or ChatStream based on capabilities)
+   - Emit events: chunk, thinking
+   - Accumulate token usage
+   - Handle truncation retries
+   
+   Reads: MessageBuffer, ContextState, ProviderCapabilities
+   Writes: ThinkState, MessageBuffer (append assistant message)
+   Result: Continue (has tool calls) | BreakLoop (no tool calls, final content)
+   
+   Replaces: loop.go lines 217-446
+
+3. PruneStage
+   - Compute history tokens via TokenCounter
+   - Phase 1 @ 70% budget: pruneContextMessages (soft-trim + hard-clear)
+   - Phase 2 @ 100% budget: compactMessagesInPlace (LLM summarization)
+   - If still over budget after Phase 2: AbortRun
+   
+   Reads: MessageBuffer, TokenCounter, context window
+   Writes: PruneState, MessageBuffer (may replace history)
+   Result: Continue | AbortRun (budget exceeded after compaction)
+   
+   Replaces: loop.go lines 352-411, loop_compact.go, pruning.go
+
+4. ToolStage
+   - Extract tool calls from ThinkState.LastResponse
+   - Generate unique tool call IDs
+   - Single tool: sequential execution
+   - Multiple tools: parallel goroutines, collect via channel, sort by index
+   - Per-tool: policy check, lazy MCP activate, execute, process result
+   - Loop detection: same-tool, read-only streak, same-result
+   - Tool budget check (totalToolCalls > maxToolCalls)
+   - Emit events: tool.call, tool.result
+   
+   Reads: ThinkState.LastResponse, ToolExecutor, WorkspaceContext
+   Writes: ToolState, MessageBuffer (append tool results)
+   Result: Continue | BreakLoop (loop killed) | AbortRun (policy denied)
+   
+   Replaces: loop.go lines 450-738, loop_tools.go
+
+5. ObserveStage
+   - Process tool results: extract deliverables, media
+   - Drain InjectCh (mid-run message injection, Point A + Point B)
+   - Check if final content ready (no tool calls + no injected messages)
+   - Sanitize final content
+   - Skill evolution postscript
+   - Publish domain events: tool.executed, run metrics
+   
+   Reads: ToolState, ThinkState, InjectCh
+   Writes: ObserveState, MessageBuffer (may append injected messages)
+   Result: Continue (more iterations needed) | BreakLoop (final content ready)
+   
+   Replaces: loop.go lines 450-466 (no-tool path), finalize portions
+
+6. CheckpointStage
+   - Every N iterations (default 5): flush pending messages to session store
+   - Crash safety: intermediate state persisted
+   - Conditional: skip if iteration % N != 0
+   
+   Reads: MessageBuffer.pending, SessionStore
+   Writes: CompactState.CheckpointFlushedMsgs, MessageBuffer (clear pending)
+   
+   Replaces: loop.go lines 748-761
+
+7. MemoryFlushStage
+   - Runs before compaction (when PruneStage detects budget pressure)
+   - Triggered by PruneStage setting a flag, NOT by iteration count
+   - Two-stage fallback: LLM flush -> extractive regex
+   - Dedup guard: once per compaction cycle
+   - Publishes: session.completed event (for episodic pipeline)
+   
+   Reads: MessageBuffer, MemoryStore, compaction config
+   Writes: CompactState.MemoryFlushedThisCycle
+   
+   Replaces: memoryflush.go, extractive_memory.go
+```
+
+### Post-Loop Pipeline (runs once after iteration loop exits)
+
+```
+8. FinalizeStage
+   - Sanitize final content (HTML entities, markdown cleanup)
+   - Media dedup + size population
+   - Flush remaining pending messages to session
+   - Token accumulation to session metadata
+   - Bootstrap auto-cleanup (delete BOOTSTRAP.md if write detected)
+   - Post-run summarization (maybeSummarize)
+   - Publish run.completed event
+   - Construct RunResult
+   
+   Reads: All substates
+   Writes: RunResult (returned to caller)
+   
+   Replaces: finalizeRun(), maybeSummarize()
+```

+
+type PipelineConfig struct {
+    MaxIterations      int
+    MaxToolCalls       int
+    CheckpointInterval int // flush every N iterations (default 5)

+
+### Execution Flow
+
+```go
+// Run executes the full pipeline for a single agent run.
+func (p *Pipeline) Run(ctx context.Context, req *agent.RunRequest) (*agent.RunResult, error) {
+    state := NewRunState(req)
+
+    // 1. Setup pipeline (once)
+    for _, stage := range p.setup {
+        if err := stage.Execute(ctx, state); err != nil {
+            return nil, fmt.Errorf("setup %s: %w", stage.Name(), err)
+        }
+    }
+
+    // 2. Iteration loop
+    for state.Iteration = 0; state.Iteration < p.maxIterations; state.Iteration++ {
+        for _, stage := range p.iteration {
+            if err := stage.Execute(ctx, state); err != nil {

+            }
+
+            // Check if stage wants to control flow
+            if swr, ok := stage.(StageWithResult); ok {
+                switch swr.Result() {
+                case BreakLoop:
+                    goto finalize
+                case AbortRun:
+                    goto finalize
+                }
+            }
+        }
+
+        // Check context cancellation (/stop)
+        if ctx.Err() != nil {
+            break
+        }
+    }
+
+finalize:
+    // 3. Finalize pipeline (once)
+    for _, stage := range p.finalize {
+        if err := stage.Execute(ctx, state); err != nil {
+            slog.Warn("finalize stage error", "stage", stage.Name(), "err", err)
+            // finalize errors are logged, not fatal
+        }
+    }
+
+    return state.BuildResult(), nil
+}
+```
+
+### Error Propagation
+
+```
+Stage returns error:
+  - Setup stage error -> abort run, return error
+  - Iteration stage error -> abort run, still run finalize
+  - Finalize stage error -> log warning, continue other finalize stages
+
+Stage returns StageResult:
+  - Continue -> next stage in iteration
+  - BreakLoop -> skip remaining iteration stages, jump to finalize
+  - AbortRun -> skip remaining stages, jump to finalize (with error flag)
+```
+

+
+## Data Flow Between Stages

+```
+ContextStage
+  writes: Workspace, ContextState, MessageBuffer.system
+     |
+     v
+ThinkStage
+  reads: MessageBuffer.All(), ContextState.OverheadTokens

+
+## MemoryFlushStage Integration with PruneStage
+
+MemoryFlushStage is NOT a regular iteration stage. It is invoked inline by PruneStage when compaction is needed.
+
+```go
+// PruneStage.Execute
+func (s *PruneStage) Execute(ctx context.Context, state *RunState) error {
+    tokens := s.tokenCounter.CountMessages(state.Model, state.Messages.All())
+    state.Prune.HistoryTokens = tokens
+
+    budget := s.contextWindow * 80 / 100 // 80% for history
+
+    // Phase 1: soft pruning at 70%
+    if tokens > budget*70/100 {
+        pruneContextMessages(state.Messages, s.config)
+        tokens = s.tokenCounter.CountMessages(state.Model, state.Messages.All())
+    }
+
+    // Phase 2: full compaction at 100%
+    if tokens > budget {
+        // Memory flush BEFORE compaction (saves memories before they're summarized away)
+        if !state.Compact.MemoryFlushedThisCycle && s.memoryFlush != nil {
+            s.memoryFlush.Execute(ctx, state) // inline call, not pipeline stage
+            state.Compact.MemoryFlushedThisCycle = true
+        }
+
+        state.Prune.MidLoopCompacted = true
+        compactMessagesInPlace(state.Messages, s.compactionConfig)
+
+        // Re-check after compaction
+        tokens = s.tokenCounter.CountMessages(state.Model, state.Messages.All())
+        if tokens > budget {
+            state.ExitCode = AbortRun
+        }
+    }
+    return nil
+}
+```
+
+---
+
+## Requirements
+
+### Functional
+- F1: Pipeline produces identical `RunResult` as current monolithic loop for same inputs
+- F2: All 7 exit conditions preserved: no-tool-calls, max iterations, truncation limit, loop kill, read-only streak, tool budget, ctx.Done
+- F3: Parallel tool execution behavior unchanged (goroutine per tool, sorted results)
+- F4: Mid-run injection (InjectCh) works at both Point A (after tools) and Point B (no tools)
+- F5: Checkpoint flush every N iterations, crash safety preserved
+
+### Non-Functional
+- NF1: No measurable latency increase from stage dispatch overhead (stages are coarse-grained)
+- NF2: Each stage independently testable with mock RunState
+- NF3: Adding new stage requires only: implement Stage interface + insert in pipeline constructor
+- NF4: RunState substates compile-time typed (no `map[string]any`)

+3. Define MessageBuffer with append/replace/flush semantics
+4. Design each stage's Execute signature and data flow
+5. Design Pipeline orchestrator with setup/iteration/finalize phases

+7. Design MemoryFlushStage inline integration with PruneStage
+8. Verify all 7 exit conditions map to StageResult values

+## Success Criteria
+
+- Every line of current `loop.go` maps to exactly one stage
+- `runState` fields fully accounted for in substates (no orphans)
+- Pipeline.Run() produces same RunResult semantics as current Loop.Run()
+- Each stage can be tested with a constructed RunState (no Loop struct dependency)
+- MemoryFlushStage integrated with PruneStage without circular dependency
+- InjectCh drain preserved at both injection points
+
+## Risk Assessment
+
+| Risk | Severity | Mitigation |
+|------|----------|------------|
+| Subtle behavior change from stage ordering | HIGH | Integration tests comparing v2 vs v3 output for same inputs. Run existing test suite. |
+| InjectCh timing sensitivity (Point A vs Point B) | MEDIUM | ObserveStage handles both points explicitly. Document injection semantics. |
+| MemoryFlushStage inline call breaks stage isolation | LOW | Acceptable trade-off: flush MUST happen before compaction. Document as intentional coupling. |
+| RunState too large (sum of substates) | LOW | Substates are small structs. Total < 500 bytes. No heap pressure. |
+| Stage interface too simple for complex stages | LOW | StageWithResult extension handles flow control. Further extension possible via StageWithCleanup etc. |
+
+## Security Considerations
+
+- ToolStage must preserve all existing security checks: policy engine, shell deny patterns, workspace restriction
+- ContextStage must preserve input guard scanning (injection pattern detection)
+- CheckpointStage flushes to session store with existing tenant scoping
+- No new attack surface introduced by pipeline refactor
+
+## Next Steps
+
+- Phase 3 (Memory & KG) adds MemoryFlushStage consumer for `session.completed` events
+- Phase 4 (System Integration) adds template-based system prompt in ContextStage
+- Phase 5 (Orchestration) may add DelegateStage or modify ToolStage for delegation

+## Overview
+
+- **Priority:** P1 (core cognitive capability)
+- **Status:** Complete
+- **Effort:** 8h design
+- **Depends on:** Phase 1 (TokenCounter for L0 budget, DomainEventBus for consolidation), Phase 2 (pipeline integration points)
+
+Design 3-tier memory system, temporal KG, consolidation pipeline, L0/L1/L2 context tiering, and smart auto-inject retrieval. This phase transforms GoClaw from append-only memory to a curated, searchable, self-maintaining knowledge system.
+
+## Key Insights
+
+- Current memory is append-only daily .md files, never revisited. Contradictions accumulate, no consolidation, no dedup
+- KG extraction is synchronous (blocks loop). Dedup thresholds hardcoded (0.98/0.90). No temporal awareness -- stale facts never expire
+- Memory search is hybrid FTS+vector but flat -- no tier awareness, no relevance-based injection
+- Karpathy insight: memory should be curated wiki, not append-only log
+- OpenViking insight: L0/L1/L2 tiering saves 10x tokens vs full-context loading
+- Graphiti insight: temporal validity windows on KG facts enable contradiction resolution
+
+---
+
+## A. 3-Tier Memory Schema
+
+### Tier 1: Working Memory
+
+In context window. No new storage needed. Managed by MessageBuffer in pipeline.
+
+- Content: recent 20-50 messages (conversation turns)
+- Lifecycle: per-turn, free (no persistence cost)
+- Size: up to 80% of context window budget
+- Pruned by: PruneStage (token-accurate via TokenCounter)
+
+### Tier 2: Episodic Memory
+
+New table. Session summaries + key interactions with pgvector embeddings.
+
+```sql
+-- Migration: 000XXX_episodic_summaries.up.sql
+
+CREATE TABLE episodic_summaries (
+    id          UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    tenant_id   UUID NOT NULL REFERENCES tenants(id) ON DELETE CASCADE,
+    agent_id    UUID NOT NULL REFERENCES agents(id) ON DELETE CASCADE,
+    user_id     VARCHAR(255) NOT NULL DEFAULT '',
+    session_key VARCHAR(500) NOT NULL,
+
+    -- Content
+    summary       TEXT NOT NULL,           -- LLM-generated session summary
+    key_entities  JSONB DEFAULT '[]',      -- entity names extracted (for downstream KG)
+    key_topics    JSONB DEFAULT '[]',      -- topic tags for BM25
+    message_count INT NOT NULL DEFAULT 0,  -- messages in summarized session
+    token_count   INT NOT NULL DEFAULT 0,  -- total tokens in session
+
+    -- Embeddings for semantic search
+    embedding     vector(1536),
+    tsv           tsvector GENERATED ALWAYS AS (to_tsvector('simple', summary)) STORED,
+
+    -- L0 abstract (pre-computed, ~50 tokens)
+    l0_abstract   TEXT NOT NULL DEFAULT '',
+
+    -- Lifecycle
+    source_id     VARCHAR(255) NOT NULL DEFAULT '', -- dedup key (session_key + compaction_count)
+    created_at    TIMESTAMPTZ DEFAULT NOW(),
+    expires_at    TIMESTAMPTZ,                      -- NULL = no expiry, default 90d from creation
+
+    UNIQUE(agent_id, user_id, source_id)
+);
+
+CREATE INDEX idx_episodic_scope ON episodic_summaries(agent_id, user_id);
+CREATE INDEX idx_episodic_tenant ON episodic_summaries(tenant_id);
+CREATE INDEX idx_episodic_created ON episodic_summaries(agent_id, user_id, created_at DESC);
+CREATE INDEX idx_episodic_expires ON episodic_summaries(expires_at) WHERE expires_at IS NOT NULL;
+CREATE INDEX idx_episodic_tsv ON episodic_summaries USING gin(tsv);
+CREATE INDEX idx_episodic_embedding ON episodic_summaries USING ivfflat (embedding vector_cosine_ops)
+    WITH (lists = 50);
+```
+
+### Tier 3: Semantic Memory
+
+Existing KG tables (`kg_entities`, `kg_relations`) + temporal fields (section B). Facts extracted from episodic summaries via consolidation pipeline. Permanent, deduplicated.
+
+No new table needed. Temporal fields added to existing tables.
+
+### Tier Flow
+
+```
+Working (Tier 1)                    Episodic (Tier 2)              Semantic (Tier 3)
+[in context window]                 [episodic_summaries]           [kg_entities + kg_relations]
+        |                                   |                              |
+        |-- session end / compaction ------>|                              |

+        |<-- kg_search ------------------------------------------->|       |
+```
+

+
+## B. Temporal KG Schema
+
+### Schema Changes
+
+```sql
+-- Migration: 000XXX_kg_temporal.up.sql
+
+-- Add temporal validity to entities
+ALTER TABLE kg_entities
+    ADD COLUMN valid_from  TIMESTAMPTZ DEFAULT NOW(),
+    ADD COLUMN valid_until TIMESTAMPTZ;  -- NULL = currently valid
+
+-- Add temporal validity to relations
+ALTER TABLE kg_relations
+    ADD COLUMN valid_from  TIMESTAMPTZ DEFAULT NOW(),
+    ADD COLUMN valid_until TIMESTAMPTZ;
+
+-- Backfill existing data: valid_from = created_at, valid_until = NULL (current)
+UPDATE kg_entities SET valid_from = created_at WHERE valid_from IS NULL;
+UPDATE kg_relations SET valid_from = created_at WHERE valid_from IS NULL;
+
+-- Partial index for current facts (most common query)
+CREATE INDEX idx_kg_entities_current ON kg_entities(agent_id, user_id)
+    WHERE valid_until IS NULL;
+CREATE INDEX idx_kg_relations_current ON kg_relations(agent_id, user_id)
+    WHERE valid_until IS NULL;
+
+-- Add configurable dedup thresholds (per-agent, stored in agents.other_config JSONB)
+-- No schema change needed -- uses existing agents.other_config field:
+-- { "kg_dedup_auto_threshold": 0.98, "kg_dedup_flag_threshold": 0.90 }
+```
+
+### Query Patterns
+
+```sql
+-- Current facts (default, most queries)
+SELECT * FROM kg_entities
+WHERE agent_id = $1 AND user_id = $2 AND valid_until IS NULL;
+
+-- Historical: what was true at a specific time?
+SELECT * FROM kg_entities
+WHERE agent_id = $1 AND user_id = $2
+  AND valid_from <= $3
+  AND (valid_until IS NULL OR valid_until >= $3);
+
+-- Supersede a fact: new contradicting fact arrives
+UPDATE kg_entities SET valid_until = NOW(), updated_at = NOW()
+WHERE agent_id = $1 AND user_id = $2 AND external_id = $3 AND valid_until IS NULL;
+-- Then INSERT new entity with valid_from = NOW()
+```
+
+### Contradiction Resolution
+
+When extraction produces a fact that contradicts an existing current fact:
+
+```
+1. Extractor produces: "User works at CompanyB" (confidence 0.85)
+2. Existing current fact: "User works at CompanyA" (confidence 0.90)
+3. If same external_id + same entity_type:
+   a. Supersede old: SET valid_until = NOW() on CompanyA fact
+   b. Insert new: CompanyB with valid_from = NOW()
+4. If different external_id but related via relation:
+   a. Flag as dedup candidate (human review)
+```
+
+### Configurable Thresholds
+
+```go
+// Per-agent KG config (stored in agents.other_config JSONB)
+type KGConfig struct {
+    DedupAutoThreshold float64 `json:"kg_dedup_auto_threshold"` // default 0.98
+    DedupFlagThreshold float64 `json:"kg_dedup_flag_threshold"` // default 0.90
+    ExtractionMinConf  float64 `json:"kg_extraction_min_conf"`  // default 0.75
+    EnableTemporal     bool    `json:"kg_enable_temporal"`       // default true
+}
+```
+
+---
+
+## C. Consolidation Pipeline
+
+Event-driven, async, non-blocking. User never waits for consolidation.
+
+### Event Flow
+
+```
+session.completed
+    |
+    v
+EpisodicWorker
+    |-- Summarize session messages via LLM
+    |-- Extract key entities (names only, for downstream)
+    |-- Generate L0 abstract (~1 sentence, ~50 tokens)
+    |-- Store in episodic_summaries
+    |-- Generate embedding (async)
+    |-- Publish: episodic.created
+    |
+    v
+SemanticExtractionWorker
+    |-- Read episodic summary
+    |-- Run KG extractor on summary (not full session -- cheaper)
+    |-- Upsert entities + relations with temporal fields
+    |-- Publish: entity.upserted
+    |
+    v
+DedupWorker
+    |-- Read newly upserted entity IDs
+    |-- Compare embeddings against existing entities
+    |-- Auto-merge (> auto_threshold + name match)
+    |-- Flag candidates (> flag_threshold)
+    |-- Handle temporal supersession for contradictions
+```
+
+### Worker Implementations
+
+```go
+// Package: internal/consolidation
+
+// EpisodicWorker processes session.completed events.
+type EpisodicWorker struct {
+    store       store.EpisodicStore
+    provider    providers.Provider // for LLM summarization
+    tokenCounter tokencount.TokenCounter
+    eventBus    eventbus.DomainEventBus
+}
+
+func (w *EpisodicWorker) Handle(ctx context.Context, event eventbus.DomainEvent) error {
+    payload := event.Payload.(eventbus.SessionCompletedPayload)
+
+    // Skip if already processed (idempotent by source_id)
+    sourceID := fmt.Sprintf("%s:%d", payload.SessionKey, payload.CompactionCount)
+    if w.store.ExistsBySourceID(ctx, event.AgentID, event.UserID, sourceID) {
+        return nil // already processed
+    }
+
+    // 1. Summarize session
+    summary, err := w.summarizeSession(ctx, payload)
+    if err != nil {
+        return fmt.Errorf("summarize: %w", err)
+    }
+
+    // 2. Extract key entities (lightweight -- name extraction, not full KG)
+    entities := extractEntityNames(summary)
+
+    // 3. Generate L0 abstract
+    l0 := generateL0Abstract(summary) // extractive: first sentence or topic sentence
+
+    // 4. Store
+    ep := &store.EpisodicSummary{
+        AgentID:      event.AgentID,
+        UserID:       event.UserID,
+        TenantID:     event.TenantID,
+        SessionKey:   payload.SessionKey,
+        Summary:      summary,
+        KeyEntities:  entities,
+        L0Abstract:   l0,
+        MessageCount: payload.MessageCount,
+        TokenCount:   payload.TokensUsed,
+        SourceID:     sourceID,
+        ExpiresAt:    timePtr(time.Now().Add(90 * 24 * time.Hour)), // 90d TTL
+    }
+    if err := w.store.Create(ctx, ep); err != nil {
+        return fmt.Errorf("store episodic: %w", err)
+    }
+
+    // 5. Publish for downstream
+    w.eventBus.Publish(eventbus.DomainEvent{
+        Type:    eventbus.EventEpisodicCreated,
+        AgentID: event.AgentID,
+        UserID:  event.UserID,
+        Payload: eventbus.EpisodicCreatedPayload{
+            EpisodicID:  ep.ID,
+            SessionKey:  payload.SessionKey,
+            Summary:     summary,
+            KeyEntities: entities,
+        },
+    })
+
+    return nil
+}
+```
+
+### Summarization Prompt (Episodic)
+
+```
+Summarize this conversation session concisely. Focus on:
+- Key decisions made
+- Facts learned about the user or project
+- Tasks completed or in-progress
+- Important technical details
+- User preferences expressed
+
+Output: 2-4 paragraph summary. Include entity names (people, projects, tools) explicitly.
+Do NOT include greetings, filler, or metadata.
+```
+
+### L0 Abstract Generation
+
+V3.0: extractive (first meaningful sentence of summary). V3.1+: LLM-generated.
+
+```go
+// generateL0Abstract produces a ~50 token abstract from episodic summary.
+// V3.0: extractive (first sentence). Future: LLM-generated.
+func generateL0Abstract(summary string) string {
+    // Split into sentences, take first non-trivial one
+    sentences := splitSentences(summary)
+    for _, s := range sentences {
+        s = strings.TrimSpace(s)
+        if len(s) > 20 { // skip very short fragments
+            if len(s) > 200 { // truncate if too long
+                s = s[:200] + "..."
+            }
+            return s
+        }
+    }
+    // Fallback: first 200 chars
+    if len(summary) > 200 {
+        return summary[:200] + "..."
+    }
+    return summary
+}
+```

+
+## D. L0/L1/L2 Context Tiering
+
+### Layer Definitions
+
+| Layer | Content | Token cost | When loaded | Storage |
+|-------|---------|-----------|-------------|---------|
+| **L0** | 1-sentence abstract | ~50 tokens | Always (auto-inject if relevant) | `episodic_summaries.l0_abstract` |
+| **L1** | Structured overview | ~200 tokens | When topic relevant | Generated on-demand, cached |
+| **L2** | Full content | Full | On-demand via tool call | `episodic_summaries.summary` (episodic) or original document (memory docs) |
+
+### L1 Generation
+
+On-demand when agent requests deeper context or auto-inject detects high relevance.
+
+```go
+// L1Cache caches generated L1 overviews. LRU, 500 entries, 1h TTL.
+type L1Cache struct {
+    cache *lru.Cache[string, string] // key: episodic_id or doc_path
+}
+
+// GenerateL1 creates structured overview from episodic summary or memory doc.
+func (c *L1Cache) GenerateL1(id string, fullContent string) string {
+    if cached, ok := c.cache.Get(id); ok {
+        return cached
+    }
+    // Extractive: key bullet points from full content
+    l1 := extractKeyPoints(fullContent, 200) // ~200 tokens budget
+    c.cache.Add(id, l1)
+    return l1
+}
+```
+
+### L2 Access
+
+Full content loaded via tool call. Agent calls `memory_search(query, depth="full")` or `memory_expand(id)`.
+
+```go
+// memory_expand tool: loads L2 full content for a specific memory entry
+// Parameters: id (episodic ID or document path)
+// Returns: full content (summary or document)
+```
+
+---
+
+## E. Smart Auto-Inject Retrieval
+
+Per-turn relevance check + L0 injection. Non-blocking, lightweight.
+
+### Flow
+
+```
+User message arrives (in ContextStage)
+    |
+    v
+1. Extract intent keywords from user message
+   - Tokenize, remove stopwords, keep nouns/verbs/proper nouns
+   - If message too short ("hello", "ok"): skip injection (no relevant context)
+    |
+    v
+2. BM25 + embedding relevance check against episodic index
+   - BM25 on episodic_summaries.tsv (fast, FTS)
+   - Embedding similarity on episodic_summaries.embedding (if available)
+   - Merge scores (configurable weights)
+    |
+    v
+3. Filter by relevance threshold
+   - Default: 0.3 (tunable per agent via agent config)
+   - If no results above threshold: skip injection
+    |
+    v
+4. Inject "## Memory Context" section into system prompt
+   - Max 5 entries, max ~200 tokens total (L0 summaries only)
+   - Format per entry: "- {topic}: {L0 abstract} [use memory_search for details]"
+    |
+    v
+5. Agent sees hint, can call memory_search for L1/L2
+```
+
+### Interface
+
+```go
+// Package: internal/memory
+
+// AutoInjector checks relevance and produces L0 injection for system prompt.
+type AutoInjector interface {
+    // Inject checks user message against memory index.
+    // Returns formatted section for system prompt, or "" if nothing relevant.
+    // Budget: max ~200 tokens of L0 summaries.
+    Inject(ctx context.Context, params InjectParams) (string, error)
+}
+
+type InjectParams struct {
+    AgentID    string
+    UserID     string
+    TenantID   string
+    UserMessage string
+    MaxEntries int     // default 5
+    MaxTokens  int     // default 200
+    Threshold  float64 // relevance threshold (default 0.3)
+}
+
+// InjectResult for observability
+type InjectResult struct {
+    Section    string   // formatted prompt section
+    MatchCount int      // total matches found
+    Injected   int      // entries injected (after budget trim)
+    TopScore   float64  // highest relevance score
+}
+```
+
+### System Prompt Section (generated by AutoInjector)
+
+```
+## Memory Context
+
+Relevant memories from past sessions (summaries only -- use memory_search for details):
+- Project Alpha: Discussed migration from PostgreSQL to CockroachDB, decided to stay with PG for now.
+- User preferences: Prefers Go over Python for backend, uses Neovim as primary editor.
+- Bug fix: Resolved auth token expiration issue in session middleware (2026-03-15).
+
+Use `memory_search` tool to retrieve full details on any topic above.
+```
+
+### Agent Config
+
+```go
+// Per-agent memory config (extends existing config.MemoryConfig)
+type MemoryConfig struct {
+    // Existing fields...
+    Enabled bool `json:"enabled"`
+
+    // V3 additions
+    AutoInjectEnabled   bool    `json:"auto_inject_enabled"`    // default true
+    AutoInjectThreshold float64 `json:"auto_inject_threshold"`  // default 0.3
+    AutoInjectMaxTokens int     `json:"auto_inject_max_tokens"` // default 200
+    EpisodicTTLDays     int     `json:"episodic_ttl_days"`      // default 90 (0 = no expiry)
+    ConsolidationEnabled bool   `json:"consolidation_enabled"`  // default true
+}
+```
+
+---
+
+## F. MemoryStore v3 Interface
+
+Extends existing `MemoryStore` with tier-aware operations.
+
+```go
+// Package: internal/store

+## Pipeline Integration Points
+
+### Where Memory/KG Connects to Pipeline Stages
+
+| Pipeline stage | Memory/KG interaction |
+|---------------|----------------------|
+| **ContextStage** | AutoInjector.Inject() -> produces ## Memory Context section |
+| **PruneStage** | Triggers MemoryFlushStage before compaction |
+| **MemoryFlushStage** | Writes to memory docs (existing). Publishes `session.completed` |
+| **FinalizeStage** | Publishes `session.completed` for episodic consolidation |
+| **ToolStage** | `memory_search` tool calls UnifiedMemorySearch |
+| **ToolStage** | `memory_expand` tool calls UnifiedMemorySearch.Expand() |
+| **ToolStage** | `kg_search` tool uses temporal queries (default: current facts) |
+
+### Consolidation Pipeline Registration
+
+```go
+// At gateway startup, register consolidation workers with DomainEventBus.
+
+func RegisterConsolidationPipeline(eb eventbus.DomainEventBus, deps ConsolidationDeps) {
+    episodicWorker := NewEpisodicWorker(deps)
+    semanticWorker := NewSemanticExtractionWorker(deps)
+    dedupWorker := NewDedupWorker(deps)
+
+    eb.Subscribe(eventbus.EventSessionCompleted, episodicWorker.Handle)
+    eb.Subscribe(eventbus.EventEpisodicCreated, semanticWorker.Handle)
+    eb.Subscribe(eventbus.EventEntityUpserted, dedupWorker.Handle)
+}
+```
+
+---
+
+## Requirements
+
+### Functional
+- F1: Episodic summaries created automatically after session completion
+- F2: L0 abstracts pre-computed at episodic creation (~50 tokens each)
+- F3: Auto-inject produces relevant L0 summaries for user messages (skip for trivial messages)
+- F4: Temporal KG queries default to current facts; historical queries via `AsOf` parameter
+- F5: Contradiction resolution: supersede old fact, insert new with valid_from = NOW()
+- F6: Dedup thresholds configurable per agent (not hardcoded)
+- F7: Consolidation pipeline non-blocking (user never waits)
+- F8: `memory_search` tool returns results with tier indicators
+- F9: `memory_expand` tool loads L2 full content
+- F10: Expired episodic entries pruned automatically (cron or lazy)
+
+### Non-Functional
+- NF1: Auto-inject latency < 50ms p99 (BM25 + embedding lookup)
+- NF2: Episodic summarization completes within 30s (LLM call)
+- NF3: Consolidation pipeline handles 100 session.completed events/minute
+- NF4: pgvector index efficient up to 100K embeddings per agent
+- NF5: L0 injection budget: max 200 tokens per turn

+## Success Criteria
+
+- episodic_summaries DDL passes `psql` validation
+- Temporal KG migration backward-compatible (existing data has valid_from=created_at, valid_until=NULL)
+- All consolidation workers idempotent (safe to replay events)
+- AutoInjector returns "" for trivial messages ("hello", "ok")
+- AutoInjector returns relevant L0s for topic-specific messages
+- UnifiedMemorySearch merges results across tiers with correct tier labels
+- Per-agent dedup thresholds configurable, defaults match current hardcoded values
+
+## Risk Assessment
+
+| Risk | Severity | Mitigation |
+|------|----------|------------|
+| Episodic summarization LLM cost | MEDIUM | Use smaller/cheaper model for summarization (e.g. GPT-4o-mini). Configurable per agent. |
+| Auto-inject false positives (irrelevant memories injected) | MEDIUM | Conservative default threshold (0.3). Agent can override. Monitor via evolution metrics. |
+| pgvector index performance at scale (100K+ embeddings) | MEDIUM | ivfflat index with lists=50. Benchmark needed. Increase lists for larger datasets. |
+| Consolidation pipeline backlog during high load | LOW | Lane-based concurrency in EventBus. Workers are idempotent. Backlog clears naturally. |
+| L0 extractive quality insufficient | LOW | Extractive is "good enough" for v3.0. LLM-generated L0 in v3.1. |
+| Temporal backfill migration slow on large KG | LOW | Backfill is simple UPDATE SET DEFAULT. Add timeout guard. |
+| Cross-agent memory leakage | HIGH | All queries scoped by tenant_id + agent_id + user_id. Verify in code review. |
+
+## Security Considerations
+
+- Tenant isolation: ALL episodic + KG queries must include tenant_id scope. Missing tenant_id = data leak.
+- User isolation: episodic summaries scoped by user_id unless shared memory enabled
+- L0/L1 content is derived from user conversations -- same access controls as original messages
+- Consolidation workers run in system context -- must not expose cross-tenant data
+- AutoInjector results filtered by same agent_id + user_id scope as memory_search
+
+## Unresolved Questions
+
+1. **Episodic TTL**: 90 days default. Should this be configurable per agent? (Likely yes, via MemoryConfig)
+2. **L0 for memory documents**: Should existing memory_documents also get L0 abstracts? (Deferred to v3.1 -- episodic first)
+3. **Cross-agent memory**: Should agents in same tenant share semantic memory? (Brainstorm Q2, deferred)
+4. **Embedding model**: Continue OpenAI text-embedding-3-small or switch to open model? (Brainstorm Q3, deferred)
+5. **Concurrent consolidation**: Multiple sessions ending simultaneously -> same episodic worker. EventBus dedup by source_id handles this, but verify ordering.
+
+## Next Steps
+
+- Phase 4 (System Integration) integrates AutoInjector into ContextStage template
+- Phase 5 (Orchestration) uses self-evolution metrics from consolidation pipeline
+- Phase 6 (Migration) handles v2 daily memory files -> episodic import

+
+## Overview
+- **Priority:** P1 (core dependency for pipeline loop + memory system)
+- **Status:** Complete
+- **Effort:** 6h design
+
+Redesigns 4 tightly-coupled systems that sit between the agent loop and the LLM:
+1. Template-based system prompt (replace string concatenation)
+2. Tool registry with typed capabilities + declarative policy
+3. Skills system with embedding search + ACL + dependency graph
+4. Retrieval integration connecting auto-inject L0 with template + tools
+
+---
+
+## Key Insights
+
+1. Current `BuildSystemPrompt()` is ~200 lines of conditional string building. 15+ sections toggled by booleans. Adding workspace enforcement language or memory context requires touching fragile concatenation logic.
+2. Tool types use 12+ optional interfaces (`InterceptorAware`, `PathAllowable`, etc.) with type assertions at registration. No capability metadata on tools themselves.
+3. PolicyEngine's 7-step pipeline works but all checks are string-based group matching. No typed capabilities (read-only vs mutating), no workspace-awareness.
+4. Skills BM25-only search misses intent-based queries ("help me debug" won't find "debugger" skill). `EmbeddingSkillSearcher` interface exists in store but not wired to loader's `BuildSummary()`.
+5. Workspace confusion root cause: system prompt text says "use relative paths" but doesn't state the enforcement rule. Template must carry WorkspaceContext enforcement language verbatim.
+
+---
+
+## Requirements
+
+### Functional
+- F1: System prompt built from Go `text/template` with embedded template file
+- F2: Each template section independently toggleable via PromptConfig
+- F3: WorkspaceContext generates explicit enforcement language (not suggestive)
+- F4: Tools declare capabilities (read-only, mutating, async, mcp-bridged) at registration
+- F5: Policy engine evaluates capabilities (e.g., "deny all mutating tools for viewer role")
+- F6: Tools receive WorkspaceContext, not raw path strings
+- F7: Skills searched by both BM25 (lexical) and embedding (semantic), results merged
+- F8: Skills filtered by agent/tenant ACL before injection
+- F9: Skill dependency graph: loader resolves + validates before activation
+- F10: Auto-inject L0 memory summaries into template's Memory section
+- F11: Provider-specific template variants (e.g., Codex needs different tool format)
+
+### Non-Functional
+- NF1: Template rendering <1ms (no LLM calls during prompt build)
+- NF2: Skill embedding search <50ms at 1000 skills
+- NF3: Backward compatible: v2 PromptConfig can produce identical v2 output
+- NF4: Template testable in isolation (no DB dependency for rendering)
+
+---
+
+## Architecture
+
+### A. Template-Based System Prompt
+
+#### PromptConfig Interface Contract
+

+```
+
+#### Template Structure
+
+Embedded template file at `internal/agent/prompt_template.go.tmpl`:
+
+```
+{{- /* System Prompt Template — v3 */ -}}
+
+{{- if .Identity -}}
+{{- template "identity" .IdentityData -}}
+{{- end -}}
+
+{{- if .Persona -}}
+# Persona
+{{ .PersonaContent }}

+
+{{- if .Instructions -}}
+# Instructions

+{{- template "team" .TeamData -}}
+{{- end -}}
+
+{{- if .ExtraPrompt -}}
+# Additional Context
+{{ .ExtraPrompt }}
+{{- end -}}
+```
+
+#### Workspace Sub-Template (Critical)
+
+```
+{{- define "workspace" -}}
+# Workspace
+- **Path:** {{ .ActivePath }}
+- **Scope:** {{ .Scope }}
+- **ENFORCED:** All file tool paths resolve relative to this directory. Absolute paths outside workspace are REJECTED.
+{{- if .ReadOnlyPaths }}
+- **Read-only access:** {{ range .ReadOnlyPaths }}{{ . }}, {{ end }}
+{{- end }}
+{{- if .SharedPath }}
+- **Shared area:** {{ .SharedPath }} (read/write by both you and delegator)
+{{- end }}
+{{- if .ContextFiles }}
+- **Managed files:** {{ range .ContextFiles }}{{ . }}, {{ end }}(system-managed, read/write intercepted to DB)
+{{- end }}
+{{- end -}}
+```
+
+#### Memory Sub-Template
+
+```
+{{- define "memory" -}}
+# Memory Context
+{{- if .L0Summaries }}
+{{- range .L0Summaries }}
+- **{{ .Topic }}:** {{ .Summary }} [use memory_search("{{ .ID }}") for details]
+{{- end }}
+{{- end }}
+{{- if .HasSearch }}
+Use `memory_search` for detailed retrieval. Use `kg_search` for relationship queries.
+{{- end }}
+{{- end -}}
+```
+
+#### PromptBuilder Interface
+
+```go
+// PromptBuilder renders system prompts from PromptConfig.
+type PromptBuilder interface {
+    Build(cfg PromptConfig) (string, error)
+}
+
+// TemplatePromptBuilder implements PromptBuilder using text/template.
+type TemplatePromptBuilder struct {
+    templates map[string]*template.Template // variant -> parsed template
+}
+
+// NewTemplatePromptBuilder loads embedded templates.
+func NewTemplatePromptBuilder() (*TemplatePromptBuilder, error)
+
+// Build renders prompt. Selects template variant from cfg.ProviderVariant.
+// Returns rendered string. Error only on template parse failure (should not happen with embedded).
+func (b *TemplatePromptBuilder) Build(cfg PromptConfig) (string, error)
+```
+
+#### Provider Variants
+
+- **Default template:** Standard Anthropic/OpenAI format
+- **Codex variant:** Tool descriptions formatted as docstrings (Codex prefers this)
+- **DashScope variant:** No streaming+tools section (DashScope limitation)
+- Variant selected by `cfg.ProviderVariant` which maps to provider capabilities
+
+---
+
+### B. Tool Registry Redesign
+
+#### Tool Capability Types
+
+```go
+// ToolCapability describes what a tool can do.
+type ToolCapability string
+
+const (
+    CapReadOnly   ToolCapability = "read-only"   // no side effects (read_file, list_files, memory_search)
+    CapMutating   ToolCapability = "mutating"     // modifies state (write_file, exec, edit)
+    CapAsync      ToolCapability = "async"        // returns immediately, result via callback
+    CapMCPBridged ToolCapability = "mcp-bridged"  // proxied to external MCP server
+)
+
+// ToolMetadata describes a tool's capabilities and requirements.
+type ToolMetadata struct {
+    Name         string
+    Capabilities []ToolCapability
+    Group        string // "fs", "web", "runtime", "memory", "team", etc.
+    RequiresWorkspace bool // tool needs WorkspaceContext
+    ProviderHints map[string]any // provider-specific hints (e.g., cache_control)
+}
+```
+
+#### Enhanced Tool Interface
+
+```go
+// Tool is the base interface all tools must implement.
+// V3 adds Metadata() for capability declaration.
+type Tool interface {
+    Name() string
+    Description() string
+    Parameters() map[string]any
+    Execute(ctx context.Context, args map[string]any) *Result
+    Metadata() ToolMetadata // NEW: declarative capability info
+}
+```
+
+> **Migration note:** Existing tools that don't implement `Metadata()` get a wrapper
+> that returns default metadata (capabilities inferred from tool group membership).
+
+#### WorkspaceContext in Tool Context
+
+```go
+// Tools access WorkspaceContext via context, not struct fields.
+// Replaces: ToolWorkspaceFromCtx(), ToolTeamWorkspaceFromCtx()
+
+func WorkspaceContextFromCtx(ctx context.Context) *WorkspaceContext
+func WithWorkspaceContext(ctx context.Context, wc *WorkspaceContext) context.Context
+```
+
+All file tools use `WorkspaceContextFromCtx(ctx)` instead of separate workspace/team-workspace context keys. WorkspaceContext carries ActivePath, ReadOnlyPaths, SharedPath — one struct, one lookup.
+
+#### Enhanced PolicyEngine
+
+```go
+// PolicyRule is a declarative access rule.
+type PolicyRule struct {
+    // Match conditions (all must match)
+    Capabilities []ToolCapability // match tools with these capabilities
+    Groups       []string         // match tools in these groups
+    Names        []string         // match specific tool names
+
+    // Action
+    Action       PolicyAction // allow or deny
+    Reason       string       // audit log reason
+}
+
+type PolicyAction string
+const (
+    PolicyAllow PolicyAction = "allow"
+    PolicyDeny  PolicyAction = "deny"
+)
+
+// PolicyEngine evaluates tool access via ordered rule list.
+// V3 adds capability-based rules alongside existing group/name rules.
+type PolicyEngine struct {
+    globalPolicy  *config.ToolsConfig
+    rules         []PolicyRule // declarative rules (evaluated in order, first match wins)
+}
+
+// FilterTools returns allowed tools. Now evaluates both legacy 7-step pipeline
+// AND declarative rules. Declarative rules take precedence.
+func (pe *PolicyEngine) FilterTools(
+    registry ToolExecutor,
+    agentID string,
+    providerName string,
+    agentToolPolicy *config.ToolPolicySpec,
+    groupToolAllow []string,
+    isSubagent bool,
+    isLeafAgent bool,
+    role string, // NEW: RBAC role ("admin", "operator", "viewer")
+) []providers.ToolDefinition
+```
+
+#### Tool Definition Generation for Providers
+
+```go
+// ToolDefAdapter generates provider-specific tool definitions.
+// Replaces direct ToProviderDef() calls.
+type ToolDefAdapter interface {
+    // ToProviderDefs converts internal tool list to provider wire format.
+    // Handles provider-specific quirks (DashScope tool format, Codex docstrings, etc.)
+    ToProviderDefs(tools []Tool, caps ProviderCapabilities) []providers.ToolDefinition
+}
+```
+
+#### Pipeline Integration
+
+ToolStage in pipeline receives registry + policy engine:
+```go
+type ToolStage struct {
+    registry     *Registry
+    policyEngine *PolicyEngine
+    adapter      ToolDefAdapter
+}
+
+// Execute runs tool, records metrics, returns result for ObserveStage.
+func (s *ToolStage) Execute(ctx context.Context, state *RunState) error
+```
+
+ObserveStage processes tool results:
+```go
+type ObserveStage struct {
+    loopDetector  *LoopDetector
+    metricsStore  EvolutionMetricsStore // record tool effectiveness
+}
+
+// Execute checks for tool loops, records metrics, decides continue/stop.
+func (s *ObserveStage) Execute(ctx context.Context, state *RunState) error
+```
+
+---
+
+### C. Skills System Upgrade
+
+#### Hybrid Search Interface
+
+```go
+// SkillSearcher provides both lexical and semantic skill search.
+type SkillSearcher interface {
+    // Search returns skills matching query, merging BM25 + embedding results.
+    // Returns at most limit results, deduplicated by slug.
+    Search(ctx context.Context, query string, limit int) ([]SkillSearchResult, error)
+
+    // SearchForAgent filters by ACL before search.
+    SearchForAgent(ctx context.Context, agentID uuid.UUID, userID string, query string, limit int) ([]SkillSearchResult, error)
+}
+
+// HybridSkillSearcher implements SkillSearcher with BM25 + embedding fusion.
+type HybridSkillSearcher struct {
+    bm25Index     *skills.Index          // existing BM25 index
+    embSearcher   store.EmbeddingSkillSearcher // existing PG embedding search
+    accessStore   store.SkillAccessStore       // ACL filtering
+    bm25Weight    float64 // default 0.4
+    embedWeight   float64 // default 0.6
+}
+```
+
+#### Score Fusion Strategy
+
+```
+1. BM25 search → top 2*limit results, normalize scores to [0,1]
+2. Embedding search → top 2*limit results, normalize scores to [0,1]
+3. Merge by slug: combined_score = bm25Weight * bm25_score + embedWeight * embed_score
+4. Sort by combined_score descending
+5. Return top limit
+```
+
+#### ACL Model
+
+```go
+// SkillVisibility controls who can see/use a skill.
+type SkillVisibility string
+
+const (
+    SkillVisibilityPublic  SkillVisibility = "public"  // all agents in tenant
+    SkillVisibilityPrivate SkillVisibility = "private" // only granted agents
+    SkillVisibilitySystem  SkillVisibility = "system"  // system-managed, immutable
+)
+
+// ACL check flow:
+// 1. If skill.Visibility == "public" → allow
+// 2. If skill.Visibility == "private" → check skill_agent_grants table
+// 3. If skill.Visibility == "system" → allow (system skills always accessible)
+// Existing SkillAccessStore.ListAccessible() already implements this.
+```
+
+No new DB tables needed. Existing `managed_skills.visibility` + `skill_agent_grants` + `SkillAccessStore` interface covers ACL. The change is wiring ACL into the search path (currently BM25 search ignores ACL).
+
+#### Dependency Graph
+
+```go
+// SkillDependency represents skill A requires skill B.
+// Stored in skill frontmatter: `depends: [slug-b, slug-c]`
+type SkillDependency struct {
+    Slug     string   // this skill
+    Requires []string // slugs of required skills
+}
+
+// DepChecker validates skill dependencies are satisfied.
+// Existing internal/skills/dep_checker.go already handles this.
+// V3 enhancement: block activation of skill with unresolved deps.
+type DepChecker interface {
+    // Check returns missing dependencies for a skill.
+    Check(slug string, available []string) []string
+
+    // ResolveOrder returns activation order respecting dependency graph.
+    // Error if circular dependency detected.
+    ResolveOrder(slugs []string) ([]string, error)
+}
+```
+
+No new DB schema. Dependencies stored in SKILL.md frontmatter `depends:` field. `dep_checker.go` already parses this. V3 adds `ResolveOrder()` for topological sort + circular detection.
+
+#### Hot-Reload Enhancement
+
+```go
+// SkillLoader manages skill discovery, loading, and hot-reload.
+// V3 adds ACL-aware loading + hybrid search integration.
+type SkillLoader interface {
+    // LoadAll discovers and loads all skills from all tiers.
+    LoadAll(ctx context.Context) error
+
+    // BuildSummary returns skill summary for system prompt injection.
+    // V3: uses HybridSkillSearcher instead of BM25-only.
+    BuildSummary(ctx context.Context, agentID uuid.UUID, userID string, query string) string
+
+    // Version returns current reload version (atomic counter).
+    Version() int64
+
+    // OnReload registers callback for hot-reload events.
+    OnReload(fn func())
+}
+```
+
+---
+
+### D. Retrieval Integration
+
+#### Auto-Inject L0 Flow
+
+```
+Per turn (in ContextStage):
+1. Extract keywords from latest user message (simple tokenization, same as BM25)
+2. Check relevance against memory index:
+   a. BM25 score against episodic summaries
+   b. Embedding similarity against semantic memory (KG entities)
+3. If max_score > agent.retrieval_threshold (default 0.3):
+   → Build L0Summaries for PromptConfig.MemoryData
+   → Cap at max_l0_tokens (default 200 tokens, counted via TokenCounter)
+4. PromptBuilder renders Memory section with L0 hints
+5. Agent sees hints, can call memory_search(id) for L1/L2 detail
+```
+
+#### Retrieval Config
+
+```go
+// RetrievalConfig controls auto-inject behavior. Per-agent configurable.
+type RetrievalConfig struct {
+    Enabled           bool    `json:"enabled"`             // default true
+    RelevanceThreshold float64 `json:"relevance_threshold"` // default 0.3
+    MaxL0Tokens       int     `json:"max_l0_tokens"`       // default 200
+    MaxL0Items        int     `json:"max_l0_items"`        // default 5
+    BM25Weight        float64 `json:"bm25_weight"`         // default 0.4
+    EmbeddingWeight   float64 `json:"embedding_weight"`    // default 0.6
+}
+```
+
+Stored in agent settings JSON (`agents.settings` column, existing JSONB field). No new DB columns.
+
+#### Retrieval Interface
+
+```go
+// Retriever performs auto-inject L0 retrieval for ContextStage.
+type Retriever interface {
+    // RetrieveL0 returns L0 summaries relevant to the query.
+    // Called once per turn in ContextStage.
+    RetrieveL0(ctx context.Context, agentID uuid.UUID, userID string, query string, cfg RetrievalConfig) ([]L0Summary, error)
+}
+
+// HybridRetriever implements Retriever using memory + KG stores.
+type HybridRetriever struct {
+    memoryStore  store.MemoryStore
+    kgStore      store.KnowledgeGraphStore
+    tokenCounter TokenCounter
+    embProvider  store.EmbeddingProvider
+}
+```
+
+#### memory_search / kg_search Tool Updates
+
+```go
+// memory_search tool gains L1/L2 mode parameter.
+// Args: { "query": "...", "depth": "l1"|"l2" }
+// L1: returns structured overview (episodic summaries, ~200 tokens each)
+// L2: returns full detail (original content, KG traversal)
+// Default: "l1" (backward compatible — current behavior is L1-equivalent)
+
+// kg_search tool gains temporal parameter.
+// Args: { "query": "...", "as_of": "2026-01-01" }
+// as_of: returns facts valid at that date. Omit = current facts only.
+```

+
+## Success Criteria
+
+1. PromptConfig can reproduce exact v2 system prompt output (regression test)
+2. All template sections independently toggleable + testable
+3. WorkspaceContext carries all info needed by file tools (no separate context keys)
+4. Every tool declares capabilities via Metadata()
+5. PolicyEngine can express "deny mutating tools for viewer role" in one rule
+6. HybridSkillSearcher returns better results than BM25-only on intent queries
+7. L0 auto-inject adds <200 tokens per turn, only when relevant
+8. Template renders in <1ms (no LLM calls)
+
+---
+
+## Risk Assessment
+
+| Risk | Severity | Mitigation |
+|------|----------|------------|
+| Template engine too rigid for edge cases | MEDIUM | Keep ExtraPrompt escape hatch. Provider variants handle outliers. |
+| Metadata() breaks all existing tool implementations | HIGH | Backward-compat wrapper: `defaultMetadata(tool)` infers from group/name. Phase implementation. |
+| Hybrid skill search slower than BM25-only | LOW | BM25 <1ms, embedding <50ms. Parallel execution. Cache embeddings. |
+| WorkspaceContext migration touches every file tool | HIGH | Single context key replaces 2. Grep for `ToolWorkspaceFromCtx` — 15 call sites. Mechanical refactor. |
+| L0 auto-inject adds latency to every turn | MEDIUM | Memory index query <10ms. Skip if no memory (hasMemory flag). Threshold prevents injection for low-relevance messages. |
+| Provider template variants diverge over time | LOW | Variants inherit from default, override only specific blocks. Test all variants in CI. |
+
+---
+
+## Security Considerations
+
+- **Template injection:** PromptConfig data (PersonaContent, InstructionContent) comes from DB. Template uses `{{ }}` not `{{ | html }}`. Since output goes to LLM (not browser), HTML escaping not needed. But ensure no Go template directives in user content — use `{{ printf "%s" .Content }}` for raw pass-through.
+- **Workspace enforcement:** WorkspaceSectionData.EnforcementMsg must be generated server-side, not from user input. Template renders it verbatim.
+- **ACL bypass:** HybridSkillSearcher MUST filter AFTER search, not before (embedding search doesn't support WHERE clauses). Verify: `ListAccessible()` called on search results.
+- **Tool capability lying:** Tools self-declare capabilities. PolicyEngine should cross-check: tools in "fs" group claiming "read-only" but actually writing. Add assertion in tests.

+## Overview
+- **Priority:** P1 (builds on Phase 4 integration layer)
+- **Status:** Complete
+- **Effort:** 6h design
+
+Designs 4 interconnected systems:
+1. **Delegate tool** — lightweight inter-agent delegation via agent_links
+2. **Orchestration mode config** — layered: spawn always, delegate base, team optional
+3. **Self-evolution** — progressive 3-stage rollout (metrics -> suggestions -> auto-adapt)
+4. **EventBus integration** — orchestration + evolution events
+
+---
+
+## Key Insights
+
+1. Agent Links infrastructure exists (`agent_link_store.go`) with `CanDelegate()`, `GetLinkBetween()`, `DelegateTargets()`, even `SearchDelegateTargetsByEmbedding()` — but NO tool uses it. Full plumbing ready, needs ~100 LOC tool wrapper.
+2. Current orchestration: spawn (self-clone, ~300 LOC) + team_tasks (9,400 LOC, 18 actions). No middle ground. Simple delegation requires team overhead or spawn limitations.
+3. Self-evolution is greenfield. No metrics infrastructure exists. Design must be additive — no existing behavior changes in Stage 1.
+4. EventBus (`bus.MessageBus`) is channel-oriented (Inbound/Outbound messages). Broadcast events are typed but payloads are `any`. V3 needs structured event types for orchestration lifecycle.
+
+---
+
+## Requirements
+
+### Functional
+- F1: `delegate` tool — agent delegates task to linked agent, async or sync
+- F2: Delegate permission checked via existing `agentLinkStore.CanDelegate()`
+- F3: Delegatee uses own workspace + optional shared area + read-only exports
+- F4: Orchestration modes configurable per tenant (default) + per agent (override)
+- F5: System prompt only shows tools for active orchestration mode
+- F6: Self-evolution Stage 1: record metrics (retrieval quality, tool effectiveness, response feedback)
+- F7: Self-evolution Stage 2: analyze metrics, generate suggestions, admin review UI
+- F8: Self-evolution Stage 3: auto-adapt with guardrails + rollback
+- F9: All orchestration lifecycle events published via EventBus
+
+### Non-Functional
+- NF1: Delegate tool adds <5ms overhead over direct agent invocation
+- NF2: Metrics recording non-blocking (goroutine, never delays response)
+- NF3: Self-evolution stages independently toggleable (feature flags)
+- NF4: Backward compatible: existing spawn + team_tasks unaffected
+
+---
+
+## Architecture
+
+### A. Delegate Tool
+
+#### Tool Interface
+
+```go
+// DelegateTool enables inter-agent task delegation via agent_links.
+// Parameters:
+//   agent_key (required): target agent key (from known delegate targets)

+//   mode (optional): "async" (default) or "sync"
+//   context (optional): additional context string passed to delegatee
+//   files (optional): list of file paths to export (read-only for delegatee)
+
+type DelegateTool struct {
+    agentLinkStore store.AgentLinkStore
+    agentStore     store.AgentStore
+    runner         AgentRunner // interface to invoke agent loop

+
+func (t *DelegateTool) Name() string { return "delegate" }
+
+func (t *DelegateTool) Metadata() ToolMetadata {
+    return ToolMetadata{
+        Name:         "delegate",

+        "required": []string{"agent_key", "task"},
+    }
+}
+```
+
+#### Execution Flow
+
+```
+delegate(agent_key="analyst", task="analyze Q1 data", mode="async")
+  |
+  v
+1. Resolve target: agentStore.GetByKey(agent_key)
+     -> fail if agent not found or inactive
+  |
+  v
+2. Permission check: agentLinkStore.CanDelegate(fromAgentID, toAgentID)
+     -> fail if no active link
+  |
+  v
+3. Get link config: agentLinkStore.GetLinkBetween(from, to)
+     -> read Settings JSON for workspace config
+  |
+  v
+4. Build WorkspaceContext for delegatee:
+     - ActivePath: delegatee's own workspace (resolved normally)
+     - SharedPath: /data/delegates/{linkID}/shared (created if not exists)
+     - ReadOnlyPaths: exported files from delegator (validated against workspace)
+     - Scope: "delegate"
+  |
+  v
+5. Build delegation request:
+     - ExtraPrompt: "Delegated task from {source_agent_key}: {task}\n{context}"
+     - WorkspaceContext: as built above
+     - Mode: PromptMinimal (subagent-style, reduced sections)
+  |
+  v
+6. Execute:
+     async mode:
+       - Spawn goroutine via scheduler lane
+       - Return immediately: "Task delegated to {agent_key}. You'll be notified on completion."
+       - On completion: bus.Broadcast(delegate.completed event)
+       - Result delivered via message bus (same as spawn announce)
+     sync mode:
+       - Block until delegatee completes (with timeout from link.Settings)
+       - Return delegatee's final response directly
+  |
+  v
+7. Emit event: bus.Broadcast("delegate.sent", DelegateSentPayload{...})
+```
+
+#### Workspace Model for Delegation
+
+```go
+// DelegateWorkspaceConfig is stored in agent_link.settings JSON.
+type DelegateWorkspaceConfig struct {
+    // SharedPath: shared directory both agents can read/write.
+    // Relative to data dir. Default: "delegates/{linkID}/shared"
+    SharedPath    string   `json:"shared_path,omitempty"`
+
+    // SourceExports: glob patterns of delegator files shared read-only.
+    // Relative to delegator's workspace. E.g., ["docs/", "data/results/"]
+    SourceExports []string `json:"source_exports,omitempty"`
+
+    // SyncTimeout: max wait time for sync mode (seconds). Default: 300
+    SyncTimeout   int      `json:"sync_timeout,omitempty"`
+
+    // MaxConcurrent: max concurrent delegations on this link. 0 = unlimited.
+    // Already exists as AgentLinkData.MaxConcurrent field.
+}
+```
+
+No new DB tables. Config stored in existing `agent_links.settings` JSONB column.
+
+#### AgentRunner Interface
+
+```go
+// AgentRunner abstracts invoking an agent's loop for delegation.
+// Implemented by the gateway's run dispatcher.
+type AgentRunner interface {
+    // RunDelegation executes a delegation task and returns the result.
+    // ctx carries workspace context, tenant scope, timeout.
+    RunDelegation(ctx context.Context, req DelegationRequest) (*DelegationResult, error)
+}
+
+type DelegationRequest struct {
+    TargetAgentID  uuid.UUID
+    SourceAgentID  uuid.UUID
+    LinkID         uuid.UUID
+    Task           string
+    Context        string
+    WorkspaceCtx   *WorkspaceContext
+    UserID         string // inherit from delegator's user context
+    TenantID       uuid.UUID
+    SyncTimeout    time.Duration // 0 = async
+}
+
+type DelegationResult struct {
+    Response   string    // delegatee's final text response
+    ToolCalls  int       // number of tool calls made
+    Duration   time.Duration
+    Error      error
+}
+```

+
+### B. Orchestration Mode Configuration
+
+#### Mode Definitions
+
+```go
+// OrchestrationMode controls which inter-agent tools are available.
+type OrchestrationMode string
+
+const (
+    // ModeSpawn: self-clone only. spawn tool available.
+    // Simplest mode. Agent can only create copies of itself for background work.
+    ModeSpawn    OrchestrationMode = "spawn"
+
+    // ModeDelegate: agent links + spawn. delegate tool available.
+    // Agent can send tasks to linked agents. Base inter-agent mode.
+    ModeDelegate OrchestrationMode = "delegate"
+
+    // ModeTeam: full team tasks + delegate + spawn. team_tasks tool available.
+    // Full lifecycle: review, approval, progress tracking.
+    // Only available when agent is member of an active team.
+    ModeTeam     OrchestrationMode = "team"
+)
+```
+
+#### Configuration Layering
+
+```go
+// OrchestrationConfig controls orchestration behavior.
+type OrchestrationConfig struct {
+    // Mode: active orchestration mode.
+    // Tenant sets default, agent overrides.
+    Mode OrchestrationMode `json:"orchestration_mode"`
+}
+```
+
+**Storage:** No new DB columns. Uses existing config mechanisms:
+- Tenant default: `tenant_settings.orchestration_mode` (existing JSONB settings column on tenants table)
+- Agent override: `agents.settings -> 'orchestration_mode'` (existing JSONB settings column)
+
+**Resolution order:**
+```
+1. Agent settings.orchestration_mode (if set)
+2. Tenant settings.orchestration_mode (if set)
+3. Default: "spawn"
+```
+
+#### Tool Visibility by Mode
+
+| Mode | spawn | delegate | team_tasks |
+|------|-------|----------|------------|
+| spawn | yes | no | no |
+| delegate | yes | yes | no |
+| team | yes | yes | yes |
+
+**Implementation:** PolicyEngine checks orchestration mode during FilterTools:
+
+```go
+// In PolicyEngine.FilterTools(), after existing 7-step pipeline:
+func (pe *PolicyEngine) applyOrchestrationMode(
+    allowed []string,
+    mode OrchestrationMode,
+    isTeamMember bool,
+) []string {
+    switch mode {
+    case ModeSpawn:
+        allowed = subtractSet(allowed, []string{"delegate", "team_tasks"})
+    case ModeDelegate:
+        allowed = subtractSet(allowed, []string{"team_tasks"})
+    case ModeTeam:
+        if !isTeamMember {
+            // Downgrade to delegate if not in team
+            allowed = subtractSet(allowed, []string{"team_tasks"})
+        }
+    }
+    return allowed
+}
+```
+
+#### System Prompt Integration
+
+PromptConfig (from Phase 4) carries orchestration info:
+
+```go
+// Added to PromptConfig:
+type OrchestrationSectionData struct {
+    Mode            OrchestrationMode
+    DelegateTargets []DelegateTargetEntry // from agentLinkStore.DelegateTargets()
+    TeamContext     *TeamSectionData      // only if ModeTeam + team member
+}
+
+type DelegateTargetEntry struct {
+    AgentKey    string
+    DisplayName string
+    Description string
+}
+```
+
+Template renders delegate targets when mode is delegate/team:
+
+```
+{{- define "orchestration" -}}
+{{- if eq .Mode "delegate" "team" }}
+# Delegation
+You can delegate tasks to these agents:
+{{- range .DelegateTargets }}
+- **{{ .AgentKey }}**: {{ .Description }}
+{{- end }}
+Use `delegate(agent_key, task)` to send work.
+{{- end }}
+{{- end -}}
+```
+
+---
+
+### C. Self-Evolution Design (Progressive)
+
+#### Stage 1: Metrics Infrastructure (v3.0)
+
+##### DB Schema
+
+```sql
+-- New table: agent_evolution_metrics
+CREATE TABLE agent_evolution_metrics (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    tenant_id UUID NOT NULL REFERENCES tenants(id),
+    agent_id UUID NOT NULL REFERENCES agents(id) ON DELETE CASCADE,
+    session_key TEXT NOT NULL,
+
+    metric_type TEXT NOT NULL,  -- 'retrieval', 'tool', 'feedback'
+    metric_key TEXT NOT NULL,   -- specific metric (e.g., tool name, retrieval query)
+    value JSONB NOT NULL,       -- metric-specific payload
+
+    created_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
+);
+
+-- Indexes for efficient querying
+CREATE INDEX idx_evo_metrics_agent_type ON agent_evolution_metrics(agent_id, metric_type);
+CREATE INDEX idx_evo_metrics_created ON agent_evolution_metrics(created_at);
+CREATE INDEX idx_evo_metrics_tenant ON agent_evolution_metrics(tenant_id);
+
+-- Partition-ready: created_at is in schema for future range partitioning
+-- For now, TTL cleanup via cron: DELETE WHERE created_at < NOW() - INTERVAL '90 days'
+```
+
+##### Metric Types
+
+```go
+// MetricType constants
+const (
+    MetricRetrieval MetricType = "retrieval"
+    MetricTool      MetricType = "tool"
+    MetricFeedback  MetricType = "feedback"
+)
+
+// RetrievalMetricValue records per-retrieval quality.
+type RetrievalMetricValue struct {
+    Query       string  `json:"query"`
+    ResultCount int     `json:"result_count"`
+    TopScore    float64 `json:"top_score"`
+    UsedInReply bool    `json:"used_in_reply"` // heuristic: result text appears in LLM output
+    Source      string  `json:"source"`        // "memory_search", "kg_search", "auto_inject"
+}
+
+// ToolMetricValue records per-tool-call effectiveness.
+type ToolMetricValue struct {
+    ToolName    string        `json:"tool_name"`
+    Success     bool          `json:"success"`     // !result.IsError
+    Duration    time.Duration `json:"duration_ms"`
+    ResultSize  int           `json:"result_size"`  // bytes
+    Capability  string        `json:"capability"`   // from ToolMetadata
+}
+
+// FeedbackMetricValue records implicit satisfaction signal.
+type FeedbackMetricValue struct {
+    Signal       string `json:"signal"`        // "correction", "followup", "thanks", "new_topic"
+    TurnGap      int    `json:"turn_gap"`      // turns between response and signal
+    PreviousTool string `json:"previous_tool"` // last tool used before signal
+}
+```
+
+##### Heuristic: "Was retrieval result used?"
+
+```
+After LLM response:
+1. Collect all retrieval results from this turn (memory_search, auto-inject L0)
+2. For each result, check if any 3+ word substring appears in LLM output
+3. Mark used_in_reply = true if found
+4. Record metric with used_in_reply flag
+```
+
+Simple substring check. Not perfect but sufficient for Stage 1 metrics. No LLM call needed.
+
+##### Implicit Satisfaction Signals
+
+```
+After user's next message:
+1. If message is a correction ("no", "that's wrong", "I meant..."): signal = "correction"
+2. If message continues topic (similar embedding): signal = "followup"
+3. If message changes topic entirely: signal = "new_topic"
+4. If message is appreciation ("thanks", "perfect"): signal = "thanks"
+5. Record feedback metric with previous turn's tool context
+```
+
+Classification via keyword matching + embedding similarity. No LLM call.
+
+##### Metrics Store Interface
+
+```go
+// EvolutionMetricsStore manages self-evolution metrics.
+type EvolutionMetricsStore interface {
+    // RecordMetric stores a single metric (non-blocking, goroutine-safe).
+    RecordMetric(ctx context.Context, metric EvolutionMetric) error
+
+    // QueryMetrics returns metrics for analysis.
+    QueryMetrics(ctx context.Context, agentID uuid.UUID, metricType MetricType, since time.Time, limit int) ([]EvolutionMetric, error)
+
+    // AggregateToolMetrics returns per-tool success rate, avg duration, call count.
+    AggregateToolMetrics(ctx context.Context, agentID uuid.UUID, since time.Time) ([]ToolAggregate, error)
+
+    // AggregateRetrievalMetrics returns per-source usage rate.
+    AggregateRetrievalMetrics(ctx context.Context, agentID uuid.UUID, since time.Time) ([]RetrievalAggregate, error)
+
+    // Cleanup removes metrics older than TTL.
+    Cleanup(ctx context.Context, olderThan time.Time) (int64, error)
+}
+
+type EvolutionMetric struct {
+    ID         uuid.UUID
+    TenantID   uuid.UUID
+    AgentID    uuid.UUID
+    SessionKey string
+    MetricType MetricType
+    MetricKey  string
+    Value      json.RawMessage // serialized *MetricValue
+    CreatedAt  time.Time
+}
+
+type ToolAggregate struct {
+    ToolName    string
+    CallCount   int
+    SuccessRate float64
+    AvgDuration time.Duration
+}
+
+type RetrievalAggregate struct {
+    Source    string  // "memory_search", "kg_search", "auto_inject"
+    QueryCount int
+    UsageRate  float64 // fraction of results used in reply
+    AvgScore   float64
+}
+```
+
+##### Pipeline Integration
+
+Metrics recorded in ObserveStage (Phase 2 pipeline):
+
+```go
+// In ObserveStage.Execute():
+// After tool result processing:
+if toolResult != nil {
+    go metricsStore.RecordMetric(ctx, EvolutionMetric{
+        MetricType: MetricTool,
+        MetricKey:  toolResult.ToolName,
+        Value:      marshalToolMetric(toolResult),
+    })
+}
+
+// After retrieval in ContextStage:
+if len(l0Results) > 0 {
+    go metricsStore.RecordMetric(ctx, EvolutionMetric{
+        MetricType: MetricRetrieval,
+        MetricKey:  "auto_inject",
+        Value:      marshalRetrievalMetric(query, l0Results),
+    })
+}
+```
+
+Always non-blocking (`go` goroutine). Metrics are best-effort — dropped on error, never block agent loop.
+
+#### Stage 2: Suggestion Engine (v3.1)
+
+##### DB Schema
+
+```sql
+-- New table: agent_evolution_suggestions
+CREATE TABLE agent_evolution_suggestions (
+    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+    tenant_id UUID NOT NULL REFERENCES tenants(id),
+    agent_id UUID NOT NULL REFERENCES agents(id) ON DELETE CASCADE,
+
+    suggestion_type TEXT NOT NULL,   -- 'threshold', 'tool_order', 'skill_add', 'memory_prune'
+    suggestion TEXT NOT NULL,         -- human-readable suggestion
+    rationale TEXT NOT NULL,          -- data-driven reasoning
+    parameters JSONB,                 -- machine-readable params for auto-apply
+
+    status TEXT NOT NULL DEFAULT 'pending',  -- 'pending', 'approved', 'rejected', 'applied', 'rolled_back'
+    reviewed_by TEXT,                 -- admin user who reviewed
+    reviewed_at TIMESTAMPTZ,
+
+    created_at TIMESTAMPTZ NOT NULL DEFAULT NOW()
+);
+
+CREATE INDEX idx_evo_suggestions_agent ON agent_evolution_suggestions(agent_id, status);
+CREATE INDEX idx_evo_suggestions_tenant ON agent_evolution_suggestions(tenant_id);
+```
+
+##### Suggestion Types
+
+```go
+type SuggestionType string
+
+const (
+    SuggestThreshold  SuggestionType = "threshold"   // adjust retrieval threshold
+    SuggestToolOrder  SuggestionType = "tool_order"   // reorder tool list for this agent
+    SuggestSkillAdd   SuggestionType = "skill_add"    // recommend adding a skill
+    SuggestMemoryPrune SuggestionType = "memory_prune" // prune low-value memory
+)
+
+// SuggestionParams is the machine-readable payload for auto-apply.
+// Each SuggestionType has its own params structure.
+type ThresholdParams struct {
+    Param    string  `json:"param"`     // "retrieval_threshold", "l0_max_tokens"
+    OldValue float64 `json:"old_value"`
+    NewValue float64 `json:"new_value"`
+}
+
+type ToolOrderParams struct {
+    ToolName   string `json:"tool_name"`
+    Action     string `json:"action"`   // "promote", "demote", "suggest_removal"
+    Reasoning  string `json:"reasoning"`
+}
+```
+
+##### Analysis Rules (Examples)
+
+```
+Rule 1: Low retrieval usage
+  IF retrieval.usage_rate < 0.2 over 7 days AND query_count > 50
+  THEN suggest: "Raise relevance_threshold from {current} to {current+0.1}"
+  REASON: "Only 20% of auto-injected memory results appear in responses"
+
+Rule 2: Tool never succeeds
+  IF tool.success_rate < 0.1 over 7 days AND call_count > 20
+  THEN suggest: "Consider removing {tool_name} or fixing configuration"
+  REASON: "{tool_name} failed 90% of {call_count} calls"
+
+Rule 3: Repeated tool usage
+  IF tool.call_count > 100/week for specific tool AND no skill exists
+  THEN suggest: "Add skill for {common_task_pattern}"
+  REASON: "{tool_name} called {count} times this week, mostly for {pattern}"
+
+Rule 4: Memory bloat
+  IF episodic_count > 500 AND avg_usage_rate < 0.05
+  THEN suggest: "Prune episodic memories older than 60 days"
+  REASON: "95% of older episodic summaries never retrieved"
+```
+
+##### Suggestion Store Interface
+
+```go
+type EvolutionSuggestionStore interface {
+    CreateSuggestion(ctx context.Context, s EvolutionSuggestion) error
+    ListSuggestions(ctx context.Context, agentID uuid.UUID, status string, limit int) ([]EvolutionSuggestion, error)
+    UpdateSuggestionStatus(ctx context.Context, id uuid.UUID, status string, reviewedBy string) error
+    GetSuggestion(ctx context.Context, id uuid.UUID) (*EvolutionSuggestion, error)
+}
+
+type EvolutionSuggestion struct {
+    ID             uuid.UUID
+    TenantID       uuid.UUID
+    AgentID        uuid.UUID
+    SuggestionType SuggestionType
+    Suggestion     string
+    Rationale      string
+    Parameters     json.RawMessage
+    Status         string
+    ReviewedBy     string
+    ReviewedAt     *time.Time
+    CreatedAt      time.Time
+}
+```
+
+##### Suggestion Engine Interface
+
+```go
+// SuggestionEngine analyzes metrics and generates suggestions.
+// Runs as periodic cron job (configurable interval, default: daily).
+type SuggestionEngine interface {
+    // Analyze runs all rules for an agent and creates pending suggestions.
+    Analyze(ctx context.Context, agentID uuid.UUID) ([]EvolutionSuggestion, error)
+
+    // AnalyzeAll runs analysis for all agents in tenant.
+    AnalyzeAll(ctx context.Context, tenantID uuid.UUID) error
+}
+
+// RuleSuggestionEngine implements SuggestionEngine with configurable rules.
+type RuleSuggestionEngine struct {
+    metricsStore    EvolutionMetricsStore
+    suggestionStore EvolutionSuggestionStore
+    rules           []AnalysisRule
+}
+
+// AnalysisRule is a single suggestion rule.
+type AnalysisRule interface {
+    // Evaluate checks if the rule fires for the given agent metrics.
+    // Returns nil if rule doesn't apply.
+    Evaluate(ctx context.Context, agentID uuid.UUID, metrics AnalysisInput) (*EvolutionSuggestion, error)
+}
+
+type AnalysisInput struct {
+    ToolAggregates      []ToolAggregate
+    RetrievalAggregates []RetrievalAggregate
+    FeedbackSummary     FeedbackSummary
+    AnalysisPeriod      time.Duration // lookback window (default 7 days)
+}
+```
+
+#### Stage 3: Auto-Adaptation (v3.2+)
+
+##### Guardrails
+
+```go
+// AdaptationGuardrails control auto-adaptation limits.
+type AdaptationGuardrails struct {
+    // MaxDeltaPerCycle: max parameter change per adaptation cycle.
+    // E.g., threshold can only change by +/- 0.1 per cycle.
+    MaxDeltaPerCycle float64 `json:"max_delta_per_cycle"`
+
+    // MinDataPoints: minimum metrics before adaptation allowed.
+    MinDataPoints    int     `json:"min_data_points"`
+
+    // RollbackOnDrop: if quality metric drops by this %, rollback.
+    RollbackOnDrop   float64 `json:"rollback_on_drop_pct"` // e.g., 20.0 = 20%
+
+    // AdminOverride: admin can lock parameters (prevent auto-change).
+    LockedParams     []string `json:"locked_params,omitempty"`
+}
+
+// Default guardrails
+var DefaultGuardrails = AdaptationGuardrails{
+    MaxDeltaPerCycle: 0.1,
+    MinDataPoints:    100,
+    RollbackOnDrop:   20.0,
+}
+```
+
+##### Adaptation Flow
+
+```
+1. SuggestionEngine.Analyze() produces suggestion with status="pending"
+2. If auto_adapt enabled for this agent:
+   a. Check guardrails (min data points, max delta, locked params)
+   b. If passes: apply parameters, set status="applied"
+   c. Record baseline quality metric
+3. After 7 days: compare quality metric to baseline
+   a. If quality dropped > RollbackOnDrop%: rollback, set status="rolled_back"
+   b. If quality stable/improved: keep, emit event
+4. Admin can always: approve pending, reject, rollback applied, lock params
+```
+
+##### Auto-Adapt Store (Extension of Suggestion Store)
+
+```go
+// Added to EvolutionSuggestionStore for Stage 3:
+type EvolutionAdaptStore interface {
+    EvolutionSuggestionStore
+
+    // ApplySuggestion applies a suggestion's parameters to agent config.
+    ApplySuggestion(ctx context.Context, suggestionID uuid.UUID) error
+
+    // RollbackSuggestion reverts an applied suggestion.
+    RollbackSuggestion(ctx context.Context, suggestionID uuid.UUID) error
+
+    // GetAdaptationHistory returns applied/rolled-back suggestions for audit.
+    GetAdaptationHistory(ctx context.Context, agentID uuid.UUID, limit int) ([]EvolutionSuggestion, error)
+}
+```
+
+##### Feature Flags
+
+```go
+// Feature flags in agent settings JSON (agents.settings column)
+type SelfEvolutionFlags struct {
+    MetricsEnabled     bool `json:"self_evolution_metrics"`     // Stage 1 (default: true for v3)
+    SuggestionsEnabled bool `json:"self_evolution_suggestions"` // Stage 2 (default: false)
+    AutoAdaptEnabled   bool `json:"self_evolution_auto_adapt"`  // Stage 3 (default: false)
+}
+```
+
+No new DB columns. Flags stored in existing `agents.settings` JSONB.
+
+---
+
+### D. EventBus Integration
+
+#### New Event Topics
+
+```go
+// Orchestration events
+const (
+    TopicDelegateSent      = "delegate:sent"
+    TopicDelegateCompleted = "delegate:completed"
+    TopicDelegateFailed    = "delegate:failed"

+
+#### Event Subscribers
+
+```go
+// Registered at gateway startup:
+
+// 1. Delegation result delivery — notifies source agent when async delegation completes
+bus.Subscribe("delegate-result-delivery", func(e bus.Event) {
+    if e.Name == TopicDelegateCompleted {

+
+## Todo List
+
+- [ ] A1: DelegateTool interface + parameters
+- [ ] A2: Delegate execution flow (async/sync)
+- [ ] A3: DelegateWorkspaceConfig schema
+- [ ] A4: AgentRunner interface
+- [ ] A5: Permission flow (CanDelegate + GetLinkBetween)
+- [ ] B1: OrchestrationMode enum + constants
+- [ ] B2: Mode resolution (tenant default + agent override)
+- [ ] B3: Tool visibility by mode in PolicyEngine
+- [ ] B4: Orchestration section in prompt template
+- [ ] C1: agent_evolution_metrics DDL + indexes
+- [ ] C2: Metric value types (retrieval, tool, feedback)
+- [ ] C3: EvolutionMetricsStore interface
+- [ ] C4: Retrieval "used in reply" heuristic
+- [ ] C5: Implicit satisfaction signal classification
+- [ ] C6: agent_evolution_suggestions DDL
+- [ ] C7: SuggestionEngine + AnalysisRule interfaces
+- [ ] C8: Initial 4 analysis rules
+- [ ] C9: AdaptationGuardrails + auto-adapt flow
+- [ ] C10: Feature flags in agent settings
+- [ ] D1: EventBus topic constants
+- [ ] D2: Typed event payloads (delegate, evolution)
+- [ ] D3: Event subscriber design (result delivery, notifications)
+
+---
+
+## Success Criteria
+
+1. DelegateTool ~100 LOC (excluding workspace setup), uses existing agentLinkStore.CanDelegate()
+2. Orchestration mode resolvable from tenant + agent settings with no new DB columns
+3. PolicyEngine correctly filters tools by mode (spawn/delegate/team)
+4. agent_evolution_metrics table handles 10K+ rows/day without index degradation
+5. Metrics recording never blocks agent loop (goroutine + best-effort)
+6. SuggestionEngine rules are additive (new rule = implement AnalysisRule interface)
+7. All orchestration events typed (no `map[string]any` payloads)
+8. Feature flags independently toggleable per agent
+
+---
+
+## Risk Assessment
+
+| Risk | Severity | Mitigation |
+|------|----------|------------|
+| Delegate tool workspace isolation leaks | HIGH | ReadOnlyPaths enforced by same resolvePath() as all file tools. SharedPath created with restricted permissions. |
+| Sync delegation timeout blocks caller | MEDIUM | Configurable timeout per link (default 300s). Timeout returns error, does not kill delegatee. |
+| Metrics table grows unbounded | MEDIUM | TTL cleanup cron (default 90 days). Partitioning-ready schema (created_at). Monitor table size. |
+| Suggestion engine generates noise | LOW | Minimum data points threshold (100). Suggestions require admin review (Stage 2). Auto-adapt has guardrails (Stage 3). |
+| Orchestration mode config not discoverable | LOW | Admin UI shows current mode per agent. CLI: goclaw agent info shows mode. |
+| Self-evolution "learns wrong" | HIGH | Progressive rollout. Stage 1 = metrics only (no behavior change). Stage 2 = human review. Stage 3 = guardrails + rollback. |
+| EventBus topic explosion | LOW | Strict naming convention. Only add topics with subscribers. No orphan topics. |
+
+---
+
+## Security Considerations
+
+- **Delegation permission:** `CanDelegate()` is the sole gate. No bypass via direct tool call — delegate tool always calls CanDelegate(). Link status "disabled" blocks delegation.
+- **Cross-tenant delegation:** Agent links are tenant-scoped (both agents must be in same tenant). `agentLinkStore` queries filter by tenant_id from context.
+- **Delegate workspace isolation:** Delegatee cannot access delegator's full workspace. Only explicitly exported paths (SourceExports) are shared read-only. SharedPath is a new directory, not inside either workspace.
+- **Metrics data sensitivity:** Metrics contain query text and tool names, not user data or PII. Scoped by tenant_id. Cleanup cron prevents accumulation.
+- **Auto-adapt scope:** Stage 3 only modifies retrieval parameters (thresholds, weights). Cannot modify tool access, workspace rules, or security settings. Admin can lock any parameter.

+- Architecture report: `plans/reports/Explore-260406-thorough-v3-architecture.md` (all sections)
+- Workspace forcing: `plans/reports/Explore-260406-workspace-forcing.md`
+- Phase 1-5 designs: all prior phase files in this plan
+- Current migrations: `migrations/000001_init_schema.up.sql` through `migrations/000036_secure_cli_agent_grants.up.sql`
+- Schema version: `internal/upgrade/version.go` (RequiredSchemaVersion = 36)
+
+## Overview
+- **Priority:** P1 (blocks implementation start)
+- **Status:** Complete
+- **Effort:** 4h design
+
+Final design phase — comprehensive migration plan, affected file inventory, test matrix, and audit checklist. Ensures no implementation begins without full impact analysis.
+
+---
+
+## Key Insights
+
+1. Current RequiredSchemaVersion = 36 (migration 000036). V3 adds 3 new tables + 2 ALTER TABLE. Next migration = 000037.
+2. KG tables (000013) lack temporal columns. Adding valid_from/valid_until via ALTER is non-breaking — NULL defaults work.
+3. Memory system is hybrid: daily .md files in filesystem + memory_documents/memory_chunks in PG. V3 must ingest filesystem files into new episodic_summaries table.
+4. Agent settings already uses JSONB — all new per-agent configs (retrieval thresholds, orchestration mode, self-evolution flags, dedup thresholds) fit without schema changes.
+5. No SQLite changes in v3 — design is PG-first per brainstorm decision #17. SQLite compat deferred.
+
+---
+
+## Requirements
+
+### Functional
+- F1: New tables created via standard golang-migrate files
+- F2: ALTER TABLE for KG temporal columns with safe defaults
+- F3: Lazy data migration: v2 data auto-converted on first access
+- F4: Feature flags per agent for gradual v3 rollout
+- F5: Full affected file inventory with dependency order
+- F6: Integration test plan covering all 6 workspace scenarios
+- F7: Rollback path for every schema change
+
+### Non-Functional
+- NF1: Migration runs <30s on databases with 100K entities
+- NF2: No downtime required — all changes additive (no DROP/RENAME)
+- NF3: v2 agents continue working unchanged until explicitly migrated
+- NF4: Test suite runnable in CI (<5 min)

+
+#### RequiredSchemaVersion Bump
+
+```go
+// internal/upgrade/version.go
+const RequiredSchemaVersion uint = 38
+```
+
+---
+
+### B. Data Migration Strategy (Dual-Mode)
+
+#### Principle: Lazy Migration on First Access
+
+V3 reads v2 format on first access, auto-migrates in background. No bulk migration script. No downtime.
+
+#### V2 Memory Files -> Episodic Summaries
+
+```
+Trigger: Agent with v3_memory_enabled=true, first session start
+Flow:
+1. Check if agent has unmigrated v2 daily files:
+   - List files matching memory/YYYY-MM-DD.md in workspace
+   - Check episodic_summaries for source_id matching file path
+   - If no matching episodic record: file is unmigrated
+2. For each unmigrated file:
+   a. Read file content
+   b. Insert episodic_summaries row:
+      - summary: file content (already summarized by v2 flush)
+      - source_type: "v2_daily"
+      - source_id: file path (dedup guard)
+      - key_topics: extract from content (simple keyword extraction)
+      - turn_count: 0 (unknown for v2)
+      - token_count: len(content) / 4 (estimate)
+   c. Generate embedding in background (non-blocking)
+3. Mark migration complete in agent settings: v2_memory_migrated=true
+```
+
+#### V2 KG Entities -> Temporal
+
+```
+Trigger: Migration 000038 runs (ALTER TABLE with defaults)
+Flow:
+1. ALTER TABLE adds valid_from DEFAULT NOW() — new rows get current timestamp
+2. Existing rows: valid_from = NOW() at migration time (not created_at)
+3. Optional backfill (non-blocking, cron job):
+   UPDATE kg_entities SET valid_from = created_at WHERE valid_from > created_at + INTERVAL '1 second';
+   UPDATE kg_relations SET valid_from = created_at WHERE valid_from > created_at + INTERVAL '1 second';
+4. valid_until remains NULL for all existing entities (all considered "current")
+```
+
+> **Decision:** Default valid_from to NOW() at migration time, not created_at. Backfill is optional — historical accuracy is nice-to-have, not required. Existing entities are "currently valid" regardless of when they were created.
+
+#### V2 Sessions -> V3 Sessions
+
+No migration needed. V3 pipeline operates on same session data. Sessions use same `sessions` table, same `SessionData` struct. V3 adds pipeline stages that wrap existing behavior.
+
+#### Feature Flags
+
+All stored in existing `agents.settings` JSONB column:
+
+```json
+{
+  "v3_pipeline_enabled": false,
+  "v3_memory_enabled": false,
+  "v3_retrieval_enabled": false,
+  "self_evolution_metrics": false,
+  "self_evolution_suggestions": false,
+  "self_evolution_auto_adapt": false,
+  "v2_memory_migrated": false,
+  "retrieval_threshold": 0.3,
+  "dedup_auto_merge_threshold": 0.98,
+  "dedup_flag_threshold": 0.90,
+  "orchestration_mode": "spawn"
+}
+```
+
+**Rollout plan:**
+1. Deploy v3 binary with all flags false (default) — no behavior change
+2. Enable v3_memory_enabled per agent — triggers lazy v2 file migration
+3. Enable v3_pipeline_enabled per agent — switches to Stage-based pipeline
+4. Enable v3_retrieval_enabled per agent — activates L0 auto-inject
+5. Enable self_evolution_metrics per agent — starts recording
+6. Enable at tenant level for bulk rollout

+
+| # | Scenario | ActivePath | Scope | Key Assertion |
+|---|----------|------------|-------|---------------|
+| 1 | Solo DM, isolated | `{base}/{userID}` | personal | Files scoped to user dir |

+|------|-------|-------|----------|
+| Context build | ContextStage | RunRequest + agent config | WorkspaceContext resolved, system prompt built |
+| LLM call | ThinkStage | Messages array | Provider called via adapter |
+| Token pruning | PruneStage | Messages exceeding 85% context | Older messages pruned, token count accurate |
+| Tool exec | ToolStage | Tool call from LLM | Tool executed via registry with policy check |
+| Loop detect | ObserveStage | 3x same tool call | Loop detected, force stop |
+| Session save | CheckpointStage | Completed run | Session persisted, events emitted |

+
+#### Regression Tests
+
+| Test | Assertion |
+|------|-----------|
+| V2 agent with all flags false | Identical behavior to pre-v3 binary |

+
+### E. Audit Checklist
+
+#### Interface Contracts
+- [ ] All interface contracts have method signatures with ctx context.Context as first param
+- [ ] All interfaces have at least one implementation (PG store)
+- [ ] No interface has >10 methods (split if so)
+- [ ] Error returns are typed (not raw string errors)
+- [ ] Context propagation: tenant_id, agent_id, user_id carried through all store calls
+
+#### DB Schemas
+- [ ] All new tables have tenant_id column with FK to tenants(id)
+- [ ] All FKs have ON DELETE CASCADE where appropriate
+- [ ] Indexes exist for: primary lookup, tenant filter, time-range queries
+- [ ] No new columns on existing tables (all config in JSONB settings)
+- [ ] Down migrations cleanly reverse up migrations
+- [ ] No PG-specific features in interface definitions (SQLite compat future)
+
+#### Data Flow
+- [ ] Memory flow: user message -> auto-inject L0 -> response -> session end -> episodic -> semantic
+- [ ] KG flow: text -> extract -> upsert -> dedup -> temporal validity
+- [ ] Pipeline flow: ContextStage -> ThinkStage -> PruneStage -> ToolStage -> ObserveStage -> CheckpointStage
+- [ ] Delegation flow: delegate() -> permission check -> workspace setup -> AgentRunner -> result delivery
+- [ ] Event flow: stage completion -> EventBus.Broadcast() -> subscriber handlers
+
+#### Breaking Changes
+- [ ] Tool.Metadata() — wrapper provided for existing tools
+- [ ] WorkspaceContext — single context key replaces 2 (grep all call sites)
+- [ ] BuildSystemPrompt() — bridge function wraps PromptBuilder
+- [ ] Pipeline stages — feature flag gates new behavior
+- [ ] Token counting — fallback to chars/4 for unknown models
+
+#### Security Review
+- [ ] Workspace isolation: WorkspaceContext.ActivePath enforced by resolvePath()
+- [ ] Delegate read-only exports: validated against delegator's workspace boundary
+- [ ] Delegate shared area: created with restrictive permissions (0750)
+- [ ] Tenant boundary: all new tables have tenant_id, all queries filter by it
+- [ ] Metrics data: no PII stored (queries + tool names, not user content)
+- [ ] Template injection: PromptConfig data passed via {{ printf "%s" }} not {{ }}
+- [ ] Auto-adapt scope: only modifies retrieval params, not security settings
+
+#### Performance Review
+- [ ] tiktoken-go: benchmark Count() for Claude models (<1ms per 1000 tokens)
+- [ ] pgvector: benchmark episodic_summaries search at 100K rows (<50ms)
+- [ ] Event bus: benchmark Broadcast throughput (10K events/sec target)
+- [ ] Template rendering: benchmark Build() (<1ms, no allocation-heavy paths)
+- [ ] L0 auto-inject: benchmark memory index query (<10ms per turn)
+- [ ] KG temporal: benchmark index scan with valid_until IS NULL filter
+- [ ] Metrics recording: verify non-blocking (goroutine, no mutex on hot path)

+| `migrations/000038_kg_temporal_columns.down.sql` | DROP added columns + indexes |
+
+### Files to Modify
+| File | Change |
+|------|--------|
+| `internal/upgrade/version.go` | RequiredSchemaVersion = 38 |
+
+### Full Affected File Count by Module
+
+| Module | Files Modified | Files Created | Total |
+|--------|---------------|---------------|-------|
+| Foundation (Phase 1) | 15 | 4 | 19 |
+| Pipeline (Phase 2) | 9 | 7 | 16 |
+| Memory & KG (Phase 3) | 14 | 4 | 18 |
+| System Integration (Phase 4) | 15 | 9 | 24 |
+| Orchestration (Phase 5) | 4 | 10 | 14 |
+| Migration (Phase 6) | 1 | 4 | 5 |
+| **Total** | **58** | **38** | **96** |
+
+---
+
+## Design Steps
+
+1. Write migration 000037 DDL (episodic_summaries, evolution tables)
+2. Write migration 000038 DDL (KG temporal columns)
+3. Write down migrations for both
+4. Document lazy v2 memory migration flow
+5. Document KG temporal backfill strategy
+6. List all feature flags with defaults
+7. Inventory all affected files per module (complete)
+8. Document breaking changes with migration path
+9. Write workspace scenario test matrix
+10. Write memory tier test scenarios
+11. Write KG temporal test scenarios
+12. Write pipeline stage test scenarios
+13. Write provider adapter test matrix
+14. Write regression test list
+15. Complete audit checklist
+
+---
+
+## Todo List
+
+- [ ] A1: Migration 000037 DDL (3 new tables)
+- [ ] A2: Migration 000038 DDL (KG temporal ALTER)
+- [ ] A3: Down migrations for both
+- [ ] A4: RequiredSchemaVersion bump to 38
+- [ ] B1: V2 memory -> episodic lazy migration design
+- [ ] B2: KG temporal backfill strategy
+- [ ] B3: Feature flags catalog with defaults
+- [ ] B4: Session v2->v3 compatibility notes
+- [ ] C1: Affected files inventory per module (complete)
+- [ ] C2: Code change dependency order
+- [ ] C3: Breaking changes list with backward-compat path
+- [ ] D1: Workspace scenario test matrix (6 scenarios)
+- [ ] D2: Memory tier tests (8 scenarios)
+- [ ] D3: KG temporal tests (6 scenarios)
+- [ ] D4: Pipeline stage tests (7 scenarios)
+- [ ] D5: Provider adapter tests (7 scenarios)
+- [ ] D6: Regression tests (5 scenarios)
+- [ ] E1: Interface contracts audit
+- [ ] E2: DB schema audit
+- [ ] E3: Data flow audit
+- [ ] E4: Breaking changes audit
+- [ ] E5: Security review
+- [ ] E6: Performance review
+
+---
+
+## Success Criteria
+
+1. Both migrations run cleanly on empty DB and on DB with existing v2 data
+2. Down migrations fully reverse up migrations (no orphaned objects)
+3. RequiredSchemaVersion matches highest migration number
+4. All 6 workspace scenarios pass integration tests
+5. V2 agents with all flags false behave identically to pre-v3
+6. Every breaking change has documented backward-compat path
+7. Audit checklist 100% complete before implementation begins
+
+---
+
+## Risk Assessment
+
+| Risk | Severity | Mitigation |
+|------|----------|------------|
+| Migration fails on large KG tables | MEDIUM | ALTER TABLE ADD COLUMN with DEFAULT is metadata-only in PG12+ (instant). No table rewrite. |
+| V2 memory files not found (path differences) | LOW | Lazy migration lists actual files in workspace. Files missing = nothing to migrate. |
+| Feature flag combinatorial explosion | MEDIUM | 6 boolean flags = 64 combos. Test key combos only: all-off (v2), all-on (v3), individual toggles. |
+| 96 affected files scope | HIGH | Implementation phased by module. Each module independently deployable behind feature flags. |
+| Episodic summaries table grows large | MEDIUM | expires_at column + cleanup cron. Index on expires_at for efficient deletion. |
+| Temporal KG backfill slow | LOW | Backfill is optional, runs as cron in background. No downtime. Default valid_from=NOW() sufficient. |
+| SQLite compat deferred too long | MEDIUM | Interfaces designed PG-agnostic. SQLite impl can be added later without interface changes. |
+
+---
+
+## Rollback Plan
+
+### Per-Migration Rollback
+```bash
+./goclaw migrate down 2  # reverts 000038, then 000037
+```
+
+### Per-Feature Rollback
+Set feature flag to false in agent settings:
+```json
+{ "v3_pipeline_enabled": false, "v3_memory_enabled": false }
+```
+Agent immediately reverts to v2 behavior. No code rollback needed.
+
+### Full v3 Rollback
+1. Disable all v3 feature flags for all agents
+2. Run `migrate down 2` to remove v3 tables
+3. Deploy v2 binary
+4. v2 memory files, KG entities, sessions — all intact (v3 tables were additive)
+
+---
+
+## Security Considerations
+
+- **Migration safety:** All changes additive (CREATE TABLE, ALTER ADD COLUMN). No DROP, RENAME, or data modification in up migration. Down migration only drops v3-added objects.
+- **Feature flag isolation:** v3 code paths gated by flags. Flag false = v2 code path. No mixed state.
+- **Tenant isolation in new tables:** All 3 new tables have tenant_id FK. All queries must include tenant_id filter. Store implementations enforce via context.
+- **Evolution metrics cleanup:** Cron job with configurable TTL (default 90 days). Prevents unbounded growth.
+- **Temporal KG queries:** Default WHERE valid_until IS NULL produces same results as pre-temporal. No data exposure from temporal columns.
+
+---

+```
+
+Items 1-4 are independent and can be built in parallel.
+Items 5-7 are independent of each other but depend on 1-4.
+Items 8-12 are sequential (migrations first, then stores, then workers).

+# GoClaw v3 Core Architecture Design
+
+## Overview
+
+Design-first plan for comprehensive v3 core redesign. Produces interface contracts, DB schemas, data flow diagrams, and dependency graphs — NOT implementation code. Implementation plans created per-phase after design audit.
+
+**Brainstorm report:** `plans/reports/brainstorm-260406-1059-goclaw-v3-core-redesign.md`
+
+## Cross-Plan Dependencies
+
+None. This plan blocks future implementation plans (to be created after design audit).
+
+## Key Decisions (from brainstorm)
+
+| # | Module | Decision |
+|---|--------|----------|
+| 1 | Loop | Pipeline stages (pluggable interfaces) |
+| 2 | Memory | 3-tier (working/episodic/semantic) |
+| 3 | Context | L0/L1/L2 progressive loading |
+| 4 | KG | Temporal validity windows |
+| 5 | Token counting | tiktoken-go accurate |
+| 6 | Consolidation | Async event-driven |
+| 7 | Retrieval | Smart auto-inject L0 + on-demand |
+| 8 | Workspace | Unified WorkspaceContext |
+| 9 | System prompt | Template-based |
+| 10 | Providers | Capability + unified wire + plugin |
+| 11 | Self-evolution | Progressive (metrics→suggest→auto) |
+| 12 | Orchestration | Layered: delegate base + team optional |
+| 13 | Tools | Redesign (registry, policy, workspace-aware) |
+| 14 | Events | Redesign (structured, typed) |
+| 15 | Skills | Semantic search + ACL + deps |
+| 16 | Context files | DB + better abstraction |
+| 17 | Migration | Dual-mode v2→v3 |
+| 18 | SQLite | Deferred |
