When use_agent is enabled, the scheduler runs the message content as a
prompt through the LangChain agent and sends Simba's response instead of
the raw content. Frontend adds an Ask Simba toggle with visual indicator.

Extend scheduled messages with a recurrence field. After sending a
recurring message, the scheduler automatically creates the next pending
occurrence. Frontend adds repeat toggle (Once/Daily/Weekly/Monthly) and
displays recurrence in the messages table.

Strip markdown formatting (bold, italic, headers, code, links, lists) from
LLM responses before sending via iMessage. Add scheduled messages feature
with CRUD API, background scheduler loop, and admin frontend panel.

Revert get_conversation_for_user to use Conversation.get() with
MultipleObjectsReturned fallback. Add channel field to Conversation
model and get_conversation_for_channel helper so each messaging
channel gets its own isolated conversation per user.

- New imessage blueprint: webhook receives inbound iMessages, runs through
LangChain agent, replies via SendBlue REST API
- Admin-only: only users with lldap_admin group can use iMessage channel
- Admin endpoints to link/unlink imessage_number on user accounts
- Add imessage_number field to User model (needs aerich migration)

Switch from gws calendar +agenda to gws calendar events list with
explicit timeMin/timeMax and singleEvents=true to include all-day events.

Adds a get_calendar_events agent tool that shells out to `gws calendar +agenda`
for admin users. Controlled by GOOGLE_CALENDAR_ENABLED env var, with OAuth
credentials mounted from credentials.json.

The async/sync engine split caused visibility issues where newly indexed
files weren't found on the next cycle, triggering re-indexing of all 36
files every 60 seconds. Replace with a module-level dict that loads from
DB on cold start and stays in sync via cache updates after each indexing.

Two fixes:
- Convert wikilinks to display text instead of stripping them entirely.
[[Noah]] becomes "Noah", [[target|display]] becomes "display". This
was causing names and references in wikilinks to be invisible to search.
- Switch _get_obsidian_indexed_files to async engine to avoid stale reads
from the separate sync engine, which caused files to be re-indexed
every cycle.

Empty documents after sanitization caused aadd_documents to issue a
DEFAULT VALUES insert. Guard with an emptiness check. Also increase
similarity search k from 2 to 6 so multi-word queries like full names
have better recall.

YAML frontmatter can contain datetime objects which aren't JSON
serializable. Add _make_serializable() to coerce all metadata values
before storing in pgvector.

Replace full delete-and-reindex with mtime-based incremental sync that
only re-indexes changed/new files and removes deleted ones. A background
polling task keeps the vector store up-to-date automatically when
OBSIDIAN_CONTINUOUS_SYNC=true.

Update from journal/YYYY/YYYY-MM-DD.md to
50 - Journal/YYYY/MM/YYYY-MM-DD.md to match the actual Obsidian vault
folder layout.

The ob CLI uses a directory lock at .obsidian/.sync.lock that persists
across container restarts via the volume mount, causing "Another sync
instance is already running" errors. Remove it before starting sync.

ob login blocks waiting for interactive input when OBSIDIAN_EMAIL or
OBSIDIAN_PASSWORD is empty. Check required env vars before attempting
login to skip sync gracefully with a warning instead of hanging.

Run ob login and sync-setup in foreground before backgrounding sync to
prevent "Another sync instance is already running" error. Restrict the
catch-all route to only serve whitelisted static file extensions to
prevent sensitive files like credentials.json from being exposed.

Replace OBSIDIAN_AUTH_TOKEN with OBSIDIAN_EMAIL/OBSIDIAN_PASSWORD and run
the full ob login → sync-setup → sync sequence on container startup so
fresh containers authenticate properly instead of failing with
"Run 'ob sync-setup' first".

Disable tiktoken pre-encoding for custom embedding servers. LangChain
was encoding text into OpenAI token IDs then sending them to llama-server
which has a different vocabulary, causing "invalid tokens" errors.

Indexes chunks one at a time with error logging to identify which
document/chunk causes embedding failures. Also strips Unicode surrogates
and replacement characters.

Strips null bytes, control characters, and excessive whitespace from
document content before sending to embedding models. Fixes 400 errors
from BERT-based tokenizers (e.g. nomic-embed-text) on PDF-extracted text.

Extract logic from god components into custom hooks (useAuthCheck,
useConversations, useChat, usePresignedUrl, useAdminUsers, useOIDCAuth).
Eliminate unnecessary useEffects per React guidelines — scroll is now
imperative, isAdmin comes from useAuthCheck instead of a separate fetch.
ConversationList becomes a pure presentational component. Wrap bubble
components in React.memo.

Shift focus from cat persona to genuine helpfulness. Keep light

_get_collection_id now catches the UndefinedTable error that occurs
before the first index operation creates the langchain tables.

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.
