Backs the schema added in 210d310 with SQLAlchemy 2.0 models.
- SessionFact: "What we know" facts with polymorphic source_ref pointing
at task-lane item UUIDs inside ai_sessions.pending_task_lane (not a FK
per Section 4.2).
- SessionSuggestedFix: AI-proposed resolutions with supersession tracking
and the full user_decision state machine.
- DraftTemplate: post-resolve templatization queue with promotion to
script_templates.
- AccountSettings: per-account JSONB preferences grab-bag with async
classmethod helpers — get_setting(db, account_id, key, default) reads
without creating, set_setting(db, account_id, key, value) upserts via
Postgres ON CONFLICT + jsonb `||` merge so existing keys are preserved.
Lazy row creation matches the Phase 1 design.
Column additions on existing models to mirror the migration:
- AISession: resolution_note_* / escalation_package_* / state_version
(the preview-cache-invalidation counter consumed by Phase 3).
- ScriptTemplate: source_session_id / source_user_id / source_ticket_ref
(provenance for templates promoted from DraftTemplate).
All four new models registered in app.models.__init__ and __all__.
TYPE_CHECKING-guarded relationship imports throughout, matching the
repo's existing model style.

Task lane questions/actions are now saved to a pending_task_lane JSONB
column on ai_sessions, restoring them on session switch or page reload.
Partial submit no longer force-clears the lane — the AI response
controls what stays. Also removes redundant "New Session" button from
the sidebar (dashboard already provides this).

SQLAlchemy SAWarning about overlapping relationships was promoted to
an error by pytest filterwarnings=error, crashing mapper initialization
and causing 500s on every request — cascading to 423+ test failures.

- Add back_populates to SessionBranch.session ↔ AISession.branches
to fix SQLAlchemy InvalidRequestError that broke all backend tests
- Remove unused 'tree' variable in command-palette.spec.ts
- Suppress setState-in-effect lint rule in TaskLane (intentional sync)

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

'requesting_escalation' is 23 characters, exceeding the varchar(20)
limit. This caused a StringDataRightTruncationError 500 on escalate.

Implements Phase 1 of the FlowPilot-First pivot — the core AI session
experience where engineers describe a problem and FlowPilot guides them
through structured diagnosis with selectable options, free-text escape
hatches, and auto-generated documentation on resolution.
Backend: AISession + AISessionStep models, FlowPilot Engine (LLM
orchestration with structured JSON output), Flow Matching Engine v1
(semantic + keyword + recency scoring), 8 API endpoints with auth,
rate limiting, and AI quota enforcement.
Frontend: Intake screen, conversational session view with sidebar,
step cards with options/actions/resolution suggestions, resolve/escalate
modals, documentation view with rating, session history integration,
and /pilot route with sidebar navigation.
