# Changelog

All notable changes to ResolutionFlow are documented here.

## [Unreleased]

### Added
- Tree Templates + Import/Export marketplace (#66)
- Recurring Issue Detection — client-specific pattern alerts (#60)
- Step Feedback Flag — "This Step is Wrong" reporting (#58)
- **Tenant Isolation Phase 0** — multi-tenant data isolation (#132) with app-layer filtering helpers (`tenant_filter()`, `get_tenant_context`), cross-tenant access audit (analytics, categories, AI sessions, trees), UUID endpoint isolation with 404 responses for unauthorized access, ownership checks on all sensitive operations, and CI grep gate for missing tenant filters
- **Tenant Isolation Phase 2** — PostgreSQL Row Level Security (RLS) on 11 session-related tables (ai_sessions, session_steps, session_tags, etc.), account_id NOT NULL enforcement on all write paths, Alembic migrations with dual-env support (Railway native vars + explicit DATABASE_URL_SYNC), RLS test coverage with cross-account isolation verification, migration CI/CD integration
- **Tenant Isolation Phase 3** — RLS on audit_logs and tree_shares tables, cross-tenant session access for public shares (via get_admin_db), complete account_id propagation across PSA integration write paths, final RLS policy enforcement
- **Script Library default view** — "All Scripts" tab now displays all accessible scripts (team + library)
- **Session documentation overhaul** — reformatted PSA resolution/escalation notes with cleaner headers, inline engineer responses, decimal hour display (0.25 hrs), follow-up recommendations, and improved "What We Know" section from evidence items
- **Client communication improvements** — new `request_info` audience type for client-facing information requests, improved status update and email draft prompts with per-context guidance
- **Image support in Assistant Chat** — paste/attach images in chat input, uploaded to S3, resized for vision model, displayed in conversation history

### Changed
- **Edit Procedure page** — layout overhaul and color system refinements for better visual hierarchy
- **Flows sidebar navigation** — collapsed to reduce visual noise; session recovery removed from library view
- **Account settings page** — audit fixes for improved consistency and usability
- **PSA documentation formatting** — removed duplicate timing blocks and AI confidence sections; added client-facing communication context guidance
- **Status update generation** — fixed option label lookup to use human-readable labels instead of machine values
- **Assistant Chat session actions** — moved Pause/Resume/Close actions from action bar to page header for consistency with FlowPilot
- **Design system token normalization** — unified FlowPilot, AssistantChat, and ScriptBuilder components to use consistent design tokens
- **Tenant data boundaries** — all session and tree endpoints now return 404 (not 403) for cross-tenant access attempts to avoid confirming resource existence

### Fixed
- **CRITICAL: Copilot tree query isolation** (#131) — user could access any tree UUID if known, exposing full tree structure to AI. Now scoped to current account with 404 for inaccessible trees.
- **AI session search isolation** — search endpoint leaked other users' sessions via OR(user_id, account_id). Now restricted to current user only.
- **Analytics endpoint isolation** — GET `/analytics/flows/{tree_id}` exposed session counts for any tree UUID. Now returns 404 if tree doesn't belong to requesting account.
- **Category tree counts** — cross-tenant row count leakage via tree_count field in GET `/categories/{id}`. Now scoped to requesting account.
- **PSA retry ownership check** — retry-psa-push had no ownership validation (CRITICAL). Now validates user ownership before allowing retry.
- **Task Lane save operation** — invalid task_lane_item UUIDs returned 403 revealing existence. Now returns 404 and uses query-level filtering.
- Dark text rendering on blue accent step-number badges across all flow types
- Script Library tab ownership filter now preserved across category and search changes
- Race conditions in script builder session creation and slug generation
- Stale async results in Assistant Chat (selectChat) no longer clobber new session task lane
- Sentry DSN hardcoded fallback removed — now uses environment variable only
- Option label resolution in status update context generation
- "Sorry something went wrong" errors in chat when rendering unsupported message types
- Task Lane stale data when creating new chat or resuming from concluded session
- Chat ref invalidation race condition between handleNewChat and async data loads
- Images now properly display in chat message history instead of blank placeholders

## [0.11.0] - 2026-03-30

### Changed
- **Landing page redesign** — replaced AI-template layout with bold hero, live chat animation, scroll-driven reveals, and FAQ section; self-contained `--lp-*` palette; electric blue accent throughout
- **Dashboard design critique** — eliminated section redundancy, differentiated card types across PerformanceCards, KnowledgeBaseCards, and TeamSummary; reduced visual noise
- **Session History** — redesigned as tabbed view (AI Sessions / Flow Sessions) with Load More pagination and domain filter chips; AI sessions now support lazy-loaded flow sessions with URL param routing to correct tab
- **Escalation Queue** — improved urgency signaling with time-based styling
- **Assistant page** — TaskLane UX improvements (confirmed-delete, restorable skipped tasks, progress counter); ChatSidebar delete confirmation flow fixed (no accidental chat switch while confirming)
- **Script Library/Builder** — design critique fixes; suggestion chips now correctly respect disabled state during generation
- **Create Flow dropdown** — simplified to two options (Troubleshooting / Procedural); removed AI generate flow and maintenance flow per pilot scope
- **Tag badges and buttons** — fixed unreadable text caused by `bg-accent` with dark foreground; tags now use elevated background with border

### Fixed
- Restored removed icon imports in MyTreesPage; added default export to SessionHistoryPage
- Fixed ternary closing brackets in KnowledgeBaseCards and TeamSummary
- Fixed `loadMoreAiSessions` race condition — stale pages from prior filter queries no longer mix with fresh results
- Fixed `--lp-btn` using `var(--color-accent)` in `landing.css` (violates lesson 104); now hardcoded to `#60a5fa`
