Spans are now emitted BEFORE execution starts with status "running" and
input visible, then updated when the step completes. This lets users see
what the system is doing during long-running LLM calls and tool executions.
- Add EmitSpanUpdate() to collector with separate update buffer
- Flush ordering: batch INSERT new spans first, then process updates
- Split LLM/tool/agent spans into start/end pairs (agent loop + subagent)
- Emit tool span end inside goroutines for parallel calls (no orphans)
- EmitSpanUpdate is a channel send — works after ctx cancellation
- Update go.mod and Dockerfile to Go 1.26
- Apply `go fix ./...` stdlib modernizations across 170+ files
- Add `go fix` to post-implementation checklist in CLAUDE.md
- Fix go fix misapplied rewrite in loop_history.go
- Add persistent media storage (internal/media/) replacing temp file deletion
- Add MediaRef type for lightweight media references in session messages
- Refactor media pipeline to use bus.MediaFile{Path, MimeType} across all channels
- Add read_document builtin tool for PDF/DOCX/XLSX analysis via Gemini native API
- Move image sanitization from Telegram to shared agent/media layer
- Add media reload for multi-turn conversations (images from last 5 messages)
- Add reply-to-message media resolution for Telegram (re-download on reply)
- Add media inventory to compaction summary to preserve awareness after truncation
- Fix coreToolSummaries for read_image, read_document, create_image tools
- Add real-time trace update events via WebSocket broadcast
- Improve trace detail UI with media refs and tool result display
Root cause: create_image tool only set ForLLM:"MEDIA:path" but never
populated result.Media. The main agent loop parses MEDIA: prefix via
parseMediaResult(), but the subagent exec loop only checked result.Media
— so media paths were silently lost for all subagent/spawn workflows.
This caused the entire downstream pipeline (task.Media → AnnounceQueue →
PublishInbound → ContentSuffix → session) to receive empty media, making
images invisible in WS chat despite Telegram working fine.
Fixes:
- create_image.go: set result.Media = []string{imagePath}
- subagent_exec.go: add MEDIA: prefix fallback parsing as safety net
Root cause: SubagentTask had no Media field. Tool results with media
(e.g. image generation) captured result.Media but it was discarded.
AnnounceQueueItem also had no Media field, so PublishInbound for
subagent announces always had empty Media — ContentSuffix never triggered.
Changes:
- Add Media []string to SubagentTask (subagent.go)
- Capture result.Media from tool executions in subagent_exec.go
- Add Media []string to AnnounceQueueItem (announce_queue.go)
- Pass task.Media through direct publish and batched announce drain
- Collect batch media in gateway.go announce queue drain callback
- Add GET /v1/files/{path} endpoint with Bearer token + query param auth
- Pre-convert media to markdown HTTP URLs in announce messages for WS channel
- Add HideInput flag to skip persisting system messages in session history
- Add fallback to append image URLs if LLM strips them from announce response
- Fix stream-to-history DOM flash by promoting streamed text locally
- Fix tool call card word-wrap and expandable arguments panel
- Fix snake_case mismatch in Message types (toolCalls → tool_calls)
- Add clickable image rendering in markdown renderer
