Auto-inject relevant memory facts into LLM context on every user turn. ...

Semantic search against the vector memory store runs in parallel with
context provider collection. Number of injected facts scales with
message length (1–3) to reduce noise on short queries. Guardrails:
min length gate, per-turn deduplication, and structured logging at
info level for observability.

Remove dead LLMBackend.stream() method ...

The method was defined on all backends (Ollama, FallbackOllama, OpenAI)
and in the base LLMBackend interface, but was never called by agent.py
or messages.py. stream_complete() covers all streaming use cases.

- navi/llm/base.py: remove abstract stream() method
- navi/llm/ollama.py: remove OllamaBackend.stream()
- navi/llm/fallback.py: remove FallbackOllamaBackend.stream()
- navi/llm/openai_backend.py: remove OpenAIBackend.stream()
- docs/tech_debt_review: mark item 54 as fixed

236 tests passing.

Detect Android OAuth client via User-Agent header ...

WebView always sends NaviAndroid/1.0 in the HTTP User-Agent, while
navigator.userAgent in JS is unreliable. Backend now detects the
Android platform from the UA header when the ?platform query param is
absent, ensuring the bridge-page flow works regardless of webclient
version.

Improve OAuth bridge page with Chrome Intent URL + fallback button ...

/auth/mobile-done now tries Chrome Intent URL for automatic app
opening, and falls back to a styled button if the browser blocks
automatic navigation to custom schemes.

- Auto-redirect: intent://...#Intent;scheme=navi;package=com.navi.client;end
- Fallback UI: card with \"Open Navi App\" button after 1.5s timeout
- Works in both Chrome (auto) and DuckDuckGo (manual tap)

Add Android deep-link OAuth bridge for WebView auth ...

Problem: Android WebView opens OAuth in external browser (Chrome).
After successful login, cookie stays in Chrome and WebView remains
unauthenticated because cookies are not shared between apps.

Solution: bridge page flow that avoids cookies entirely for mobile.

Backend:
- /auth/login accepts ?platform=android and ?return_to params
- /auth/callback detects android via state metadata, skips cookie,
  redirects to /auth/mobile-done?sid=<session_id>
- /auth/mobile-done renders HTML that deep-links to navi://auth/callback

Webclient:
- login() detects NaviAndroid UA and adds ?platform=android

Android:
- MainActivity: handle incoming navi:// intent in onCreate and onNewIntent,
  set cookie via CookieManager, reload WebView
- AndroidManifest: add intent-filter for navi://auth/callback and
  singleTask launchMode

Add per-user sessions and memory filters in admin panel ...

Backend:
- GET /admin/memory now accepts user_id query param to filter facts
  for a specific user instead of returning the global view.

Frontend:
- Users table now has "Sessions" and "Memory" buttons per row.
- Clicking "Sessions" switches to Sessions tab and pre-fills search
  with the user id.
- Clicking "Memory" switches to Memory tab and passes user_id to the
  API, showing only that user's facts.
- Manual tab clicks reset filters (search / userId) so the view
  returns to unfiltered state.

Docs:
- docs/api.md updated with user_id param for GET /admin/memory.

Fix admin memory showing 0 facts; add pagination/search/sort ...

Bug fix:
- get_all_facts(user_id=None) was filtering for user_id IS NULL only,
  so admin panel showed 0 facts when facts had user_ids set.
- Added all_users parameter to get_all_facts and fact_count.
- Admin endpoint now passes all_users=True to return all facts.

Memory pagination:
- Extended get_all_facts with offset, search, sort_by, sort_order params.
- Extended fact_count with search and all_users params.
- /admin/memory endpoint now accepts limit, offset, search, sort_by,
  sort_order and returns {total, limit, offset, items}.

Admin panel frontend:
- Added server-side search with debounce for memory facts.
- Added sortable column headers (category, key, source, confidence, updated).
- Added pagination controls (prev/next, page size selector).
- Switched memory display from grouped tables to flat sortable table.

Tests:
- Added unit tests for get_all_facts(all_users=True) and
  fact_count(all_users=True).
- All 219 tests pass.

- Add pagination controls (prev/next, page size selector, item count)
- Debounce search input (300ms)

Tests:
- Add integration tests for pagination, offset, search, and sorting
- All 217 tests pass

Fix memory system bugs: deterministic summary id, skip legacy extraction ...

- _summary.py: replace non-deterministic hash() with zlib.crc32 so
  summary id stays stable across server restarts, preventing duplicate
  summary rows.
- extractor.py: skip memory extraction for legacy sessions (user_id=None)
  — ON CONFLICT(user_id, category, key) does not catch NULL duplicates
  in PostgreSQL (NULL != NULL).
- sessions.py: _process_stale_sessions skips legacy sessions.
- _facts.py: remove dead code (user_clause/user_param variables).
- test_extractor.py: add user_id to test sessions + new test for
  legacy session skip.

Fix memory system multi-user bugs: summary PK conflict and vector search params ...

- _summary.py: generate deterministic per-user id (hash(user_id)+2) instead of
  hardcoded id=1, preventing UniqueViolationError on memory_summary_pkey
  for multi-user sessions.
- _facts.py: split vector search into user_id=None / user_id!=None branches
  with correct parameter counts, fixing InterfaceError "expects 3 arguments".

Fix missing columns in navi_users: add boot-time ALTER TABLE migration ...

The navi_users table already existed on this deployment, so the updated
CREATE TABLE IF NOT EXISTS was a no-op. Run ALTER TABLE ADD COLUMN for
username, first_name, last_name, phone, birth_date, country, city, locale
if they are missing (checked via information_schema.columns).

Propagate user profile to LLM context via current_user_info ContextVar ...

- Extend User model: username, first_name, last_name, phone, birth_date,
  country, city, locale (all from gnexus-auth profile)
- navi_users DDL: add new profile columns
- auth/deps + auth/callback: populate new fields on upsert
- /auth/me: return all profile fields
- Add current_user_info ContextVar for full user profile propagation
- websocket + messages: set current_user_info before agent.run()
- run_ephemeral: inherit and restore current_user_info
- ContextBuilder: _user_context_msg() injects [User context] with name,
  email, location, locale, role into LLM system messages
- _security_policy_msg: reads user_id/role from ContextVar directly

Add multi-user sandbox: filesystem, terminal, code_exec, security policy ...

- filesystem, share_file: sandbox non-admin users to user_data/<user_id>/
- terminal: working_dir sandbox + allowlist + dangerous pattern block for users
- code_exec: sandbox CWD and temp files to user_data/<user_id>/ for users
- context_builder: inject dynamic security policy into LLM context (user/admin)
- config: terminal_user_allowed_commands setting
- agent: wire user_id/user_role through ContextBuilder.build()
- base: add current_user_role ContextVar; run_ephemeral inherits role

Add per-user filesystem sandbox via current_user_id ContextVar ...

- tools/base.py: add current_user_id ContextVar (set by Agent before
  every tool call, cleared after)
- core/agent.py: set current_user_id in run_stream from session.user_id
  and in run_ephemeral from parent_session.user_id; restore in finally
- tools/filesystem.py: _check_path resolves all paths inside
  user_data/<user_id>/ when current_user_id is present; legacy mode
  (no user_id) falls back to FS_ALLOWED_PATHS
- tools/share_file.py: validate source path is inside user sandbox

Use configured GNAUTH_REDIRECT_URI instead of dynamic base_url ...

_get_redirect_uri was building the redirect_uri from request.base_url,
which returns the internal address when behind a reverse proxy. This
caused gnexus-auth to reject the redirect_uri as invalid.

Now _get_redirect_uri always returns settings.gnauth_redirect_uri,
so the public URL configured in .env is used consistently.

Fix stop_session 422: use get_current_user instead of get_current_user_ws ...

stop_session is an HTTP endpoint but was using Depends(get_current_user_ws),
whose websocket parameter caused FastAPI to demand it as a query param.

Fix NameError in run_ephemeral: session was undefined ...

run_ephemeral doesn't have a session variable. Pass user_id from the

Add full-screen login overlay for unauthenticated users ...

- Backend: new endpoint GET /auth/status returns {configured: bool}
- Webclient auth store: add authConfigured ref + fetchStatus()
- LoginScreen.vue: centered card with logo, title, and login button
- App.vue: show LoginScreen overlay when auth is configured but
  user is not authenticated (z-index 9999, blocks all UI)
- App.vue onMounted: fetch auth status before trying to resolve user

Fix WebSocket 403 — bypass FastAPI Depends for WS auth ...

- websocket.py: resolve user by calling get_current_user_ws directly
  inside the handler instead of using Depends(). This avoids FastAPI
  returning HTTP 403 on the upgrade request when auth resolution fails.
- websocket.py: accept WebSocket before access check, close with 4003
  for auth failures instead of HTTP 403.
- auth/deps.py: remove debug logging from get_current_user_ws.
- tests/conftest.py: monkeypatch get_current_user_ws directly since
  Depends() is no longer used on the WebSocket endpoint.
