Consolidate onto PostgreSQL by using pgvector instead of a separate
ChromaDB instance. This removes a Docker volume, a large dependency,
and simplifies the stack without meaningful performance impact at
our document scale.
- Swap langchain-chroma for langchain-postgres (PGVector)
- Use pgvector/pgvector:pg16 Docker image with init script
- Lazy-initialize vector store to avoid eager DB connections
- Add SQL helpers for stats/delete/list (replacing _collection access)
- Remove legacy main.py, chunker, petmd scraper, and /api/query endpoint
Re-index required after deploy (POST /api/rag/index + /index-obsidian).

Remove the useEffect on selectedConversation.id that race-conditions
with handleQuestionSubmit — it fetches the (still-empty) conversation
and wipes messages, sending the user back to the empty state. Refresh
conversation list after streaming completes instead to pick up the
auto-generated title.

Give the LangChain agent a save_user_memory tool so users can ask it to
remember preferences and personal facts. Memories are stored per-user in
a new user_memories table and injected into the system prompt on each
conversation turn.

Conversations are now returned sorted by most recently updated first.
New conversations are named using the first 100 characters of the
user's initial message instead of a username+timestamp placeholder.

Use `claims.get("groups") or []` instead of `claims.get("groups", [])`
so that an explicit `null` value is coerced to an empty list, preventing
a ValueError on the non-nullable ldap_groups field.

Access tokens now last 1 hour (up from default 15 min) and refresh
tokens last 30 days, reducing frequent re-authentication.

Memoize blob URL creation to prevent leak on every keystroke, wrap
MessageInput in React.memo with stable useCallback props, remove
expensive backdrop-blur-sm from chat footer, and use instant scroll
during streaming to avoid queuing smooth scroll animations.

Add missing pendingImage, onImageSelect, and onClearImage props to the
MessageInput rendered in the active chat footer, matching the homepage version.

- Remove unused image_url from upload response and TS type
- Remove bare except in serve_image that masked config errors as 404s
- Add error state and broken-image placeholder in QuestionBubble

Browser <img> tags can't attach JWT headers, causing 401s. The image
endpoint now returns a time-limited presigned S3 URL via authenticated
API call, which the frontend fetches and uses directly.

Use the same llama-server (OpenAI-compatible API) for vision analysis
that the main agent uses, with OpenAI fallback. Sends images as base64
in the standard OpenAI vision message format.

Users can now attach images in the web chat for Simba to analyze using
Ollama's gemma3 vision model. Images are stored in Garage (S3-compatible)
and displayed in chat history.
Also fixes aerich migration config by extracting TORTOISE_CONFIG into a
standalone config/db.py module, removing the stale aerich_config.py, and
adding missing MODELS_STATE to migration 3.

The get_transactions() method was truncating results to 50 by default,
causing incomplete transaction data. The YNAB API returns all matching
transactions in a single response, so this limit was unnecessary and
caused count/total inconsistencies.

Adds manifest.json, service worker with static asset caching,
resized cat icons, and meta tags for iOS/Android installability.

Move blueprints.email.helpers import from module-level to inside the
endpoint functions that use it, breaking the circular dependency chain.

Users can now receive a unique email address (ask+<token>@domain) and
interact with Simba by sending emails. Inbound emails hit a Mailgun
webhook, are authenticated via HMAC token lookup, processed through the
LangChain agent, and replied to via the Mailgun API.
- Extract shared SIMBA_SYSTEM_PROMPT to blueprints/conversation/prompts.py
- Add email_enabled and email_hmac_token fields to User model
- Create blueprints/email with webhook, signature validation, rate limiting
- Add admin endpoints to enable/disable email per user
- Update AdminPanel with Email column, toggle, and copy-address button
- Add Mailgun env vars to .env.example
- Include database migration for new fields

Use 100dvh for proper mobile browser chrome handling and increase
cat icon sizes across sidebar, mobile header, and empty state.

- Convert date strings to datetime.date objects before passing to API (strict Pydantic validation rejects strings)
- Use txn.var_date instead of txn.date (renamed in SDK v2 to avoid Python builtin conflict)
- Migrate BudgetsApi → PlansApi and update method names accordingly

Show centered cat icon + "Ask me anything" + input when no messages
exist. Transition to scrollable messages + bottom input once chat
starts. Auto-create a conversation on first message if none selected.
