All admin endpoints query across tenants without a tenant context.
get_db (app-role, subject to RLS) was never imported and would crash
at runtime — replace all 6 occurrences with get_admin_db (BYPASSRLS).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Phase 4 enabled RLS on the users table. All code paths that touch users
(or other RLS-protected tables) before require_tenant_context sets
app.current_account_id must use get_admin_db (BYPASSRLS):
- deps.py: get_current_user and get_current_active_user → get_admin_db
- auth.py: all endpoints → get_admin_db (login, register, refresh, etc.
run before tenant context exists; mutation endpoints also need session
consistency since current_user is in the admin session)
- accounts.py: transfer_ownership, leave_account, delete_account
→ get_admin_db (these mutate current_user directly)
- onboarding.py: dismiss_onboarding → get_admin_db (same reason)

- trees.py: change account_id=current_user.account_id →
account_id=tree.account_id so super-admin cross-account shares land in
the tree's tenant where RLS will see them.
- migration a05e1a1bea7c: fix backfill to join tree_shares → trees instead
of tree_shares → users(created_by). Same logic: historical shares belong
to the tree's tenant.
- test_tree_sharing.py: add test_share_account_id_matches_tree_not_actor
to assert share.account_id == tree.account_id after POST /share; also
add missing account_id to all direct TreeShare(...) constructors in
existing tests.
- test_phase1_migrations.py: remove team_id= from TargetList constructor
(column dropped in Phase 3).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
P3-A: Add account_id to audit_logs model + migration (backfill via user_id →
users.account_id). log_audit() gains optional account_id param with fallback
SELECT to avoid churn across 40 call sites.
P3-B: Add account_id to tree_shares model + migration (backfill via created_by
→ users.account_id). TreeShare constructor updated in trees.py.
P3-C: Enable RLS on 6 remaining tables: step_ratings, step_usage_log,
target_lists, session_shares, audit_logs, tree_shares.
P3-D: Drop team_id from target_lists — endpoint, schema, and model now use
account_id as the sole isolation key.
P3-E: Append Phase 3 RLS isolation tests for all 6 tables.
test_target_lists.py: fix cross-account test to use Account model (not Team)
and set account_id on new User.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Service layer (production code):
- branch_manager: set account_id on SessionBranch (root + fork) and ForkPoint
from session.account_id; load session in create_fork for this purpose
- handoff_manager: set account_id on SessionHandoff from session.account_id
- ai_suggestions endpoint: set account_id on AISuggestion from current_user
- steps endpoint (/feedback): set account_id on StepRating from current_user
- ratings endpoint: set account_id on StepRating from current_user
Test infrastructure:
- conftest.py: seed PLATFORM_ACCOUNT_ID (00000000-...-0001) account after
Base.metadata.create_all so global categories and gallery items have a valid FK
- test_rls_isolation: add _ensure_rls_schema fixture that runs
'alembic upgrade head' before module tests — previous function-scoped
test_db fixtures drop the schema, leaving the RLS tests with no tables
- test_branding: create Account before User in helper functions
- test_admin_gallery: set account_id=PLATFORM_ACCOUNT_ID on Tree/ScriptTemplate
- test_public_templates: set account_id=PLATFORM_ACCOUNT_ID on Tree,
ScriptTemplate, TreeCategory
- test_resolution_outputs: set account_id=session.account_id on
SessionResolutionOutput
- test_analytics_phase5: set account_id on PsaPostLog
- test_draft_trees: replace account_id=None with PLATFORM_ACCOUNT_ID in
migration default test (NOT NULL now enforced)
- test_maintenance_schedules: set account_id on other_tree
- test_save_session_as_tree: set account_id on all 5 Session() constructors
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Backend: start_session, prepare_session, batch_launch_sessions all missing
account_id=current_user.account_id — Phase 1 NOT NULL constraint made these
500 in test suite (test_ratings.py fixture couldn't create sessions).
Frontend ESLint:
- TaskLane.tsx: suppress react-refresh/only-export-components for clearTaskState
- TeamSummary.tsx: init loading from isAccountOwner to avoid sync setState in effect
- ScriptBodyEditor.tsx: move lastValueRef.current assignment into useEffect

After migration 174f442795b7 enforces NOT NULL on account_id, all
platform/global content must use the sentinel platform account instead
of NULL. Three categories of fixes:
1. trees.py: is_default trees now get PLATFORM_ACCOUNT_ID (not None)
2. admin_categories.py: global category CRUD now uses PLATFORM_ACCOUNT_ID
3. categories.py, tags.py, step_categories.py: creation endpoints coerce
None → PLATFORM_ACCOUNT_ID; IS NULL filter queries updated to
== PLATFORM_ACCOUNT_ID (IS NULL queries returned empty after migration
backfilled all global rows to the platform account)
Defines PLATFORM_ACCOUNT_ID constant in app/core/service_account.py.

* docs: add background job isolation policy to tenant isolation spec
Documents policy for all 5 existing background jobs:

- Chat Retention already follows correct pattern (model for others)
- Maintenance Schedule Firing needs account_id in queries + Session creation
- AI Conversation Expiry approved as cross-tenant with justification
Adds approved cross-tenant query registry and Phase 2 checklist items.

* docs: add tenant isolation Phase 0 implementation plan
8 tasks covering: CRITICAL copilot hotfix, tenant_filter() helper,
get_tenant_context dependency, analytics/category/AI session gap fixes,
full UUID endpoint audit, TargetList dead code audit, teams orphan
check, and CI grep check for missing tenant filters.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* feat: add tenant_filter() helper and get_tenant_context dependency
tenant_filter(model, account_id) is the canonical app-layer tenant
scoping expression. Every query on a tenant table must use it.
build_tree_access_filter and build_step_visibility_filter updated
to call tenant_filter() internally for the account_id match.
get_tenant_context is a FastAPI dependency that returns account_id
or raises 403 if the user has no account — prevents raw access to
current_user.account_id and centralises the null check.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix: scope analytics/flows/{tree_id} to requesting account
Any authenticated user could read flow analytics (session counts,
completion rates, CSAT) for any tree UUID. Now returns 404 if the
tree doesn't belong to the requesting account.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix: scope category tree_count to requesting account
tree_count on GET /categories/{id} was including trees from all
accounts, leaking cross-tenant row counts.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix: restrict AI session search to current user only
Search endpoint used OR(user_id, account_id), exposing other users'
problem_summary and problem_domain within the same account. Sessions
are user-scoped only — cross-user access requires explicit escalation
or sharing. List and search endpoints now behave consistently.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix: add ownership check and 404 responses to ai-sessions endpoints
Cross-tenant isolation audit found:
- retry-psa-push had NO ownership check (CRITICAL) — any user could retry any session's PSA push
- save_task_lane used db.get() without ownership filter, returned 403 revealing existence
- get_session returned 403 instead of 404 for unauthorized access
- stream_documentation returned 403 instead of 404
All now use query-level user_id filtering and return 404 to avoid revealing existence.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix: return 404 instead of 403 for cross-tenant session access
All session endpoints (get, update, complete, scratchpad, variables, export,
ticket-link) now return 404 instead of 403 when a user tries to access
another user's session. This prevents confirming existence of resources
across tenant boundaries.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix: return 404 instead of 403 for cross-tenant tree access
get_tree and update_tree now return 404 when a user cannot access a tree
(private tree from another account). Prevents confirming resource existence
across tenant boundaries.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix: return 404 instead of 403 for cross-tenant step access
get_step_or_404 now returns 404 when can_view_step or can_edit_step fails,
preventing confirmation of step existence across tenant boundaries.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix: return 404 instead of 403 for cross-tenant upload access
get_upload_url and delete_upload now return 404 when the upload belongs to
a different account/user, preventing resource existence confirmation.

* fix: return 404 instead of 403 for cross-tenant share access
revoke_share and create_share now return 404 when the caller is not the
owner, preventing resource existence confirmation across users.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix: return 404 instead of 403 for cross-team tree access in maintenance schedules
_get_tree_or_403 now returns 404 when the user's team does not match,

* fix: return 404 instead of 403 for cross-account step category access
get_step_category now returns 404 for account-specific categories that
belong to another account, preventing resource existence confirmation.

* test: add cross-tenant isolation tests for Task 6 UUID audit
Tests cover:
- Tree GET/PUT returns 404 for cross-account access
- Session GET returns 404 for cross-user access
- AI session GET returns 404 for cross-user access
- AI session retry-psa-push requires ownership
- Upload URL returns 404 for cross-account access
- Share revoke returns 404 for cross-user access
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix: return 404 (not 403) for get_documentation cross-user access; add missing Task 6 tests
get_documentation was revealing session existence via 403. Added pre-check
query filtering by session_id AND user_id before calling the engine.
Also add cross-tenant isolation tests for steps, tags, step_categories,
and maintenance_schedules endpoints fixed in Task 6 (TDD was skipped).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix: address Task 6 quality review — rename helper, restore 403 for intra-account, add docs test
- Rename _get_tree_or_403 → _get_tree_or_404 in maintenance_schedules.py
(function now raises 404, old name was misleading)
- Restore HTTP 403 for intra-account permission failures in update_tree:
same-account users who can see a tree but can't edit it got 404 (wrong);
only cross-account lookups should return 404 to avoid confirming existence
- Apply same 403/404 distinction to update_tree_visibility
- Add test: get_documentation must return 404 for cross-user session access
- Add comment documenting owner-only design for documentation endpoints

* chore: Task 7+8 — TargetList audit, CI tenant-filter grep check
Task 7: TargetList dead code audit
- Found active code references in 12+ files across backend and frontend
(full CRUD API + frontend page + MaintenanceScheduleSection + BatchLaunchModal)
- Decision: migrate to account_id in Phase 1 (cannot drop)
- DB row count not available from code-server — must verify from VPS SSH
before Phase 1 migration
- Teams orphan check query documented; must run from VPS SSH before Phase 1
- Results documented in spec Section 9
Task 8: CI tenant-filter enforcement check (warn mode)
- Create backend/scripts/check_tenant_filters.py
Scans endpoint and service files for select() on tenant tables without
tenant_filter/account_id/user_id in surrounding context. Currently
reports 109 warnings (Phase 1 backlog). Exits 0 (warn mode).
- Add Check tenant filter enforcement step to backend CI job
Add --fail flag after Phase 1 backlog clears to make it blocking.

_build_session_detail was omitting pending_task_lane, is_branching, and
active_branch_id from the GET /ai-sessions/{id} response. The fields
existed on the schema and model but were never passed in the manual
constructor, so task lane state could never be restored on navigation.
Also adds console logging to AssistantChatPage selectChat flow to
diagnose message restoration, and fixes ScriptTemplateEditor stepper
dismiss firing during programmatic script_body updates.

Add PUT /ai-sessions/{id}/task-lane endpoint that saves the full task
lane state (AI questions/actions + user's in-progress responses) to
the pending_task_lane JSONB column. TaskLane debounce-saves to the
backend every 2s after changes. On session load, user responses are
restored from the backend into sessionStorage so TaskLane picks them
up on mount. Users can now close the browser, come back later, and
find their task lane exactly where they left it.

Integrates ResolutionOutputGenerator into the resolve endpoint so that

Adds _generate_ai_description background task that fires after a
successful upload: images get a one-sentence vision description via

response. Errors are logged and swallowed.

The old /assistant/chats/* CRUD endpoints and assistant_chat_service
chat functions were unused — the frontend exclusively uses
/ai-sessions/{id}/chat (unified_chat_service) for all chat operations.
Removed:
- Chat CRUD endpoints (create, list, get, send, delete, conclude)
- assistant_chat_service: create_chat, send_message,
generate_conclusion_summary, CONCLUSION_SYSTEM_PROMPT
- Frontend: assistantChatApi chat methods, dead types
(AssistantChat, AssistantChatMessage, ConcludeChatRequest, etc.)
Kept:
- /assistant/retention endpoints (used by ChatRetentionSettingsPage)
- Shared AI infrastructure (_call_ai, _call_anthropic_cached,
ASSISTANT_SYSTEM_PROMPT, _auto_title) — imported by unified_chat_service
Moved:
- fetch_upload_images + resize_image_for_vision → storage_service.py
(shared location, not tied to dead endpoint)
Also added "Image Analysis" section to system prompt so Claude knows
to describe attached screenshots.
-650 lines of dead code removed.

The frontend calls /ai-sessions/{id}/chat (unified_chat_service), not
/assistant/chats/{id}/messages (assistant_chat_service). The previous
commit wired images into the wrong backend. This fixes it:
- ai_session.py schema: add upload_ids to ChatMessageRequest
- ai_sessions.py endpoint: fetch images via _fetch_upload_images
- unified_chat_service: accept and forward images to _call_ai
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Backend: ChatMessageRequest accepts upload_ids, endpoint fetches
images from S3, base64-encodes them, passes to Claude as multimodal
content blocks (vision API)
- Backend: add download_file() to storage_service for fetching from S3
- Frontend: handleSend collects completed upload IDs from pendingUploads
and includes them in the sendChatMessage API call
- Frontend: prefill handler passes upload IDs from dashboard nav state
- Enables paste-screenshot → AI-sees-it flow end-to-end

Add session_type ('guided'|'chat') and title columns to ai_sessions,
enabling both FlowPilot guided sessions and assistant chat sessions to
live in a single table. This is the foundation for a unified session
history and consistent UX across both interaction modes.
Backend:
- Migration 066: session_type + title columns
- unified_chat_service: chat sessions on ai_sessions with same AI/RAG
- POST /ai-sessions supports session_type='chat' creation
- POST /ai-sessions/{id}/chat for chat messages
- DELETE /ai-sessions/{id} for session deletion
- session_type filter on GET /ai-sessions
Frontend:
- AssistantChatPage rewired to aiSessionsApi (no more assistantChatApi)
- /assistant/:sessionId route for deep-linking
- Session history: type filter pills (All/Guided/Chat), type icons
- Dashboard: both types shown with correct routing and icons
- Fixed glass-border → border-default in dashboard components
