msg_metadata maps to the 'metadata' DB column ('metadata' is reserved
by SQLAlchemy Declarative API). to_dict() exposes the key as 'metadata'
for frontend compatibility.

Add session_version to users table. Sessions now carry session_version
alongside user_id; @login_required rejects any session where the version
doesn't match the DB value.
- migration 0024: session_version INTEGER NOT NULL DEFAULT 1
- models/user.py: session_version Mapped[int] column
- auth.py: version mismatch → session.clear() + 401
- services/auth.py: change_password and reset_password_with_token both
increment session_version, evicting all other live sessions
- routes/auth.py: login/register/oauth_callback store session_version;
update_password rehydrates current session with new version so the
user who changed their password stays logged in
Existing sessions will require one re-login after the migration runs.

NoteEditorView: two-column sidebar layout (project/milestone/tags/assist
always visible), removed assist toggle button, InlineAssistPanel removed.
Writing assist: whole_doc mode rewrites entire document; DiffView.vue
replaces editor during review showing full-document diff. Scope dropdown
in sidebar switches between whole-document and section modes.
Persistent drafts: migration 0022 adds note_drafts (UNIQUE per note+user)
and note_versions (max 20, auto-pruned) tables. Draft saved after generation
completes, restored on editor mount, cleared on accept/reject. Version
snapshot created automatically whenever note body changes on save.
HistoryPanel.vue: version list + DiffView modal, restore button writes
body back to editor.
Config: OLLAMA_NUM_CTX default raised to 65536; assist num_predict now
tracks Config.OLLAMA_NUM_CTX instead of a hardcoded 4096.

Images found via SearXNG are fetched server-side, stored on disk, and
served from /api/images/<id> — the user's browser never contacts the
original image host. Original URLs are preserved for citation.
New files:
- alembic/versions/0016_add_image_cache.py — image_cache table
- src/fabledassistant/models/image_cache.py — SQLAlchemy model
- src/fabledassistant/services/images.py — fetch/store/serve logic
- src/fabledassistant/routes/images.py — GET /api/images/<id>
Modified:
- config.py: IMAGE_CACHE_DIR (/data/images), IMAGE_MAX_BYTES (5 MB)
- research.py: _search_searxng_images() — SearXNG categories=images
- tools.py: _IMAGE_TOOLS def + search_images branch in execute_tool
- intent.py: search_images routing rule (explicit visual language only)
- app.py: register images_bp
- docker-compose.yml: image_cache named volume mounted at /data/images
- ToolCallCard.vue: "image_search" label

Without pool_pre_ping, stale pooled connections (left over after a Postgres
restart or network blip) cause immediate query failures. SQLAlchemy then
propagates the error rather than transparently reconnecting, which crashes
the Quart request handler and triggers a Swarm restart loop.
- pool_pre_ping=True: issues a lightweight SELECT 1 before each checkout;
discards and replaces stale connections silently
- pool_recycle=1800: recycles connections every 30 minutes to prevent
long-idle connections from going stale at the TCP/firewall level

- New NoteEmbedding model + migration 0014 stores float embeddings (JSONB)
- services/embeddings.py: get_embedding, upsert_note_embedding,
semantic_search_notes (cosine similarity), backfill_note_embeddings
- build_context() now tries semantic search first, falls back to keyword search;
accepts cached_note_ids to reuse last-turn notes and stabilise the system
prompt prefix for Ollama's KV cache
- generation_buffer.py: per-conversation note ID cache (get/set/clear)
- generation_task.py: passes cached IDs into build_context, updates cache
after each turn, and invalidates it after create_note/update_note/create_task
- app.py: pulls nomic-embed-text at startup and launches a background backfill
to embed all existing notes (30 s delay so Ollama has time to load the model)
- routes/notes.py + services/tools.py: fire-and-forget embedding update on
every note create or update via the API or LLM tool calls
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Ollama tool/function calling integration allows the LLM to create tasks,
create notes, and search existing notes on behalf of the user during chat.
Multi-round tool loop (max 5 rounds) lets the model execute tools then
produce a natural language response. Tool results are persisted in a new
JSONB column on messages and rendered as compact cards with linked titles.
- Migration 0013: add tool_calls JSONB column to messages
- New services/tools.py: tool definitions + execute_tool dispatcher
- llm.py: ChatChunk dataclass, stream_chat_with_tools(), date in system prompt
- generation_task.py: multi-round tool call loop with SSE tool_call events
- Frontend: ToolCallRecord type, streamingToolCalls in store, ToolCallCard
component, rendering in ChatMessage and ChatView streaming bubble

Users who forget their password can now request a reset link via email.
Tokens are SHA-256 hashed before storage, expire after 1 hour, and
previous unused tokens are invalidated on new requests. The forgot-password
endpoint always returns success to prevent email enumeration.
