A long underscore-heavy filename (no natural break points) overflowed the card toward the 3-dots menu: the title <h3> was a flex item without min-w-0, so it couldn't shrink below its min-content width, and wrap-break-word doesn't reduce flex min-content. Add min-w-0 flex-1 + wrap-anywhere on the title and shrink-0 on the menu column so the title shrinks, breaks anywhere, and stays left of the menu (still line-clamp-3).
The ResizeObserver/size effect ran once on mount with [] deps while loading=true, so containerRef was null (the graph container isn't in the DOM yet) and size.width stayed 0, gating out ForceGraph2D (blank canvas) even though the data loaded. Re-run the measure effect on [loading, data.nodes.length] so it attaches + measures once the container actually mounts.
Meaningful self-loop degree assertion (was always-true); single import style per module; explicit returns in the live-store helper. (CI code-quality bot.)
GraphStore.get_graph_overview (top-N by degree, bounded) + get_node_detail (description + linked chunks). GET /api/sources/<id>/graph + /graph/node/<id> (read-access gated, node scoped to source_id; empty graph -> {nodes:[],edges:[]}). Frontend GraphView (react-force-graph-2d) wired to config.kind=graphrag via card-click/'View graph'; node-click -> description + chunks; tooltip renders untrusted names as text (no innerHTML XSS). All read-only GraphStore methods rollback their txn (no idle-in-transaction lock). Unit G7. (Also a pre-existing prettier fix in WorkflowPreview to keep lint green.)
graph_enabled() sets kind=graphrag + retriever=graphrag. extract_graph_worker fetches the source's pgvector chunks and runs G3 extraction (graphrag_available guard, empty no-op). extract_graph durable+idempotent task; key varies with source updated_at so re-ingest/re-enable re-run incrementally (G3 checkpoint skips done chunks) while concurrent same-state enqueues dedup. The 4 ingest paths enqueue after embed when kind=graphrag (isolated in try/except so a broker hiccup can't fail the ingest). POST /api/sources/<id>/graphrag/enable: pgvector+GRAPHRAG_ENABLED gated, owner/editor write-authz; PATCH config still can't flip kind->graphrag. Unit G4.
Per-chunk schema-constrained LLM extraction (gleanings off, one .gen() per chunk) into the GraphStore: model resolves config.graph.extraction_model -> GRAPHRAG_EXTRACTION_MODEL -> instance LLM_NAME; token_usage logged per call (_token_usage_source=graph_extraction, owner-attributed via decoded_token); chunk text fenced as untrusted; robust JSON parse (malformed/errors skip the chunk, never crash); resumable via graph_ingest_progress; max_chunks cap; entity names embedded + merged by normalized_name; chunk_id = doc_id so links match retrieval. Unit G3.
On-demand graph_nodes/graph_edges/graph_node_chunks/graph_ingest_progress in the same DB as pgvector documents (no Alembic, no cross-DB FK; Python uuids; parameterized SQL). upsert_node (merge by normalized_name, doc_freq, dedup description), add_edge (+degree), link_node_chunk, search_nodes_by_embedding (cosine), bounded get_subgraph, checkpoint, delete_by_source. Embedding dim derived from the configured model (768 fallback). Unit G2.
The add-source grid inverts black icons to white (dark:invert), but the wiki used book.svg (fill #6A4DF4), which inverted to lime. Point the wiki ingestor at a new black book-mono.svg so it renders white like the others; book.svg stays purple for its other use (PromptsModal, no invert there).
sources.tokens was only set at ingest, so wikis showed no/stale token count on the card (blank wikis showed nothing; converted ones showed the stale original count). rebuild_wiki_directory_structure (called after every wiki mutation) now also sets sources.tokens to the sum of wiki_pages.token_count; blank wiki create sets tokens=0. So the card reflects live wiki content.
A converted source keeps its origin type (e.g. crawler) with the wiki-ness in config.kind=wiki (D5/D20), so the UI's type==='wiki' checks treated converted sources as normal (wrong view, convert action still offered). Sources.tsx now keys isWiki + the view branch on config.kind==='wiki' (with a type fallback for blank-created wikis). The paginated endpoint already returns config.
Clicking a source card opens its view via the existing setDocumentToView handler (wiki -> WikiViewer, nested -> FileTree/ConnectorTree, else -> Chunks). The 3-dots Button and both DropdownMenuContent menus stopPropagation so clicks on the trigger or menu items don't bubble (through the React tree, even though Radix portals them) to the card's onClick. Adds cursor + keyboard/role a11y matching AgentCard.
convert_source_to_wiki now builds pages from the source's already-ingested vector-store chunks instead of re-parsing storage files, so it works for crawler/remote/connector sources (which have no stored files; file_path empty). Groups by metadata file_path/file_name (URL- and connector-aware; URLs normalized to virtual paths) rather than the raw source. Passes embeddings_key to create_vectorstore in BOTH convert and reembed_wiki_page (fixes a TypeError crash on faiss/elasticsearch). Conservative overlap-trim (min length). Deletes the original chunks after reassembling so retrieval has no duplicate/stale content.
Unit 7 of F-Wiki (D20/D23/D24). Source row action 'Convert to wiki' (owner/editor only) -> confirm naming the cost (lossy/one-way/skipped) -> poll task status -> after-summary; blank source enables inline. Agent wiki writes (create/str_replace/insert/delete/rename) render as a prominent top-level card in the conversation (outside the collapsed tool-calls accordion) with the page path; reads stay normal. 'Living wiki'/agent-editable naming + explainer; 'New wiki' blank-source fast path retained.
Unit 6 of F-Wiki (D22 + D24). Migration 0024 adds wiki_pages.updated_via; set to 'agent' by WikiTool + convert, 'human' by the edit/seed endpoints (content-hash short-circuit preserves it). WikiViewer gains a markdown editor (Save via PUT with expected_version; 409 reloads latest while keeping the draft; 403 graceful) and a per-page provenance stamp (editor/when/version). Edit gated on write access client-side; backend remains the real authz.
Unit 5 of F-Wiki (D20-D23). convert_source_to_wiki task reuses reingest's storage file-load + parser to materialize files->wiki_pages (one page/file), skips/reports non-text, re-embeds per page, and flips kind=wiki + exposure=agentic_tool only when pages were created. POST /wiki/convert (explicit, write-authz; blank source enables inline, fileful enqueues the task; rejects mid-ingest). PUT /wiki/page for human edits (write-authz, optimistic version -> 409, re-embed). PATCH /config preserves kind (kind changes only via convert).
Unit 4 of F-Wiki. POST /api/sources/wiki creates a type=wiki/kind=wiki source with no ingest task (optional seed page enqueues reembed). GET /wiki/pages + /wiki/page serve the tree + fresh page content, read-access gated (owner or team grant), path-validated. Frontend: 'Create Wiki' ingestor entry, read-only WikiViewer (FileTree + react-markdown, no raw HTML), sync/reingest hidden for wiki sources.
Unit 3 of F-Wiki. WikiTool (view/create/str_replace/insert/delete/rename) over wiki_pages: exact-case unique str_replace (no silent multi-replace), optimistic version on edits (WikiPageConflict), reads served fresh from Postgres, untrusted-content fencing on reads, 1MB page cap. Injected via add_wiki_tool only for writable wiki sources (effective_write_owner: owner/team-editor; viewers get nothing), scoped to one source_id. Each mutation enqueues reembed_wiki_page (owner as user, per-page idempotency key) and rebuilds directory_structure. Shared validate_tool_path extracted from MemoryTool.
Per-page re-embed (Unit 2 of F-Wiki): targeted delete of the page's old chunks, re-chunk via the source's chunking config, add_chunk with reingest-matching metadata (source=path), set embed_status embedded/failed. Durable + idempotent (key=content_hash), mirroring reingest_source_task. Missing page => purge only.
Migration 0023_wiki_pages (source-scoped; version/content_hash/embed_status; FK source_id->sources ON DELETE CASCADE; UNIQUE(source_id,path) + prefix index). WikiPagesRepository: path-keyed CRUD with content-hash short-circuit, version bump, and move-with-reject. BaseVectorStore.delete_chunks_by_source_path (loop default) + parameterized pgvector override (DELETE WHERE source_id=%s AND metadata->>'source'=%s). Unit 1 of F-Wiki.
Group eyebrow headers with short live/re-ingest tags, lighter field labels, hairline dividers between rows, compact right-aligned controls, and hide the single-option Retriever select.
