FlowPilot AI sends markdown-formatted instructions but FlowPilotStepCard
was rendering them as plain <p> tags, producing an unreadable wall of text.
Switch to the existing MarkdownContent component for proper formatting.

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.

VITE_PUBLIC_POSTHOG_KEY and VITE_PUBLIC_POSTHOG_HOST must be available
at build time for Vite to bake them into the JS bundle. Without ARG/ENV
in the Dockerfile, Railway env vars are only available at runtime which
is too late for Vite's import.meta.env substitution.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Switch from apiKey+options pattern to explicit posthog.init() before
render, then pass client instance to PostHogProvider. This is more
reliable and matches the PostHog SDK docs' recommended client pattern.
Enables autocapture and pageview tracking per PostHog defaults.
Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Install @posthog/react and wrap app with PostHogProvider
- Use VITE_PUBLIC_POSTHOG_KEY and VITE_PUBLIC_POSTHOG_HOST env vars
- Use defaults: '2026-01-30' for recommended settings
- Remove manual initAnalytics() call — Provider handles initialization
- Analytics module now checks posthog.__loaded for readiness

* feat: add paletteIntent utility for command palette query classification
Detects query intent ('question' | 'keyword' | 'page' | 'empty') to drive
smart result ordering in the enhanced command palette.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add recentFlows localStorage utility for command palette empty state
Tracks recently visited flows (capped at 10) with deduplication by id,
surfaced in command palette when query is empty.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: rewrite CommandPalette with categorized results and smart ranking
- Adds FlowPilot AI result (always present when query is non-empty)
- Intent-aware ordering: question → FlowPilot prominent; page → pages first;
keyword → FlowPilot at top with flows/sessions/tags below
- Pages section with admin-gated items (uses useAuthStore)
- Tags extracted from flow search results with ?tag= navigation
- Quick Actions for create/import/scripts
- Empty state shows recent flows + quick actions
- Grouped rendering with section labels per design system
- Keyboard nav flattened across groups
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add FlowPilot prefill handoff from command palette to AssistantChatPage
When navigated to /assistant with location.state.prefill, automatically
creates a new chat and sends the prefill message without user interaction.
Clears location state after handling to prevent re-trigger on back navigation.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: track recently visited flows for command palette empty state
Calls addRecentFlow after tree data loads in both TreeNavigationPage and
ProceduralNavigationPage so the command palette can surface recent flows
when the query is empty.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* refactor: use useMemo instead of useCallback for groups builder in CommandPalette
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add PSA ticket context Pydantic schemas (Task 6)
Add TicketDetails, CompanyInfo, ContactInfo, ConfigItem, TicketNote,
RelatedTicket, and TicketContext models in schemas/psa_context.py for
structured ticket context enrichment used by AI prompt injection.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add ticket context prompt formatter (Task 7)
format_ticket_context_for_prompt() in services/psa/ticket_context.py
serializes TicketContext into structured text for AI system prompts,
with 10-note limit, 200-char text previews, and human-readable timestamps.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add get_ticket_context() to ConnectWise provider (Task 8)
Fetches ticket details, company, contact, configurations, notes, and
related open tickets in parallel via asyncio.gather with partial failure
tolerance. Results are cached with a 5-minute TTL per ticket/connection.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add GET /integrations/psa/tickets/{id}/context endpoint (Task 9)
Returns rich TicketContext for a ticket ID. Handles PSA auth failures
(returns structured error), ticket-not-found (404), and general PSA
errors (502). Requires active PSA connection for the user's account.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: inject PSA ticket context into copilot system prompt (Task 10)
When a copilot conversation has an associated session with a linked PSA
ticket, fetch the ticket context and append it to the system prompt.
Failure is non-critical — errors are logged and the copilot proceeds
without context rather than failing the request.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add PSA context API client with TypeScript interfaces
Defines TicketDetails, CompanyInfo, ContactInfo, ConfigItemInfo,
TicketNote, RelatedTicket, and TicketContext interfaces matching backend
psa_context.py schemas. Exports psaContextApi with getTicketContext().
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add useTicketContext hook for PSA ticket context fetching
Accepts psaTicketId and psaConnectionId, fetches context on mount
when both IDs are present, and exposes refresh() for manual re-fetch.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add TicketContextPanel component with accordion sections
Glass-card panel showing ticket summary, status/priority/SLA, and
accordion sections for Client, Contact, Devices, Notes, and Related
tickets. Matches design system with font-label labels and ice-cyan accents.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: mount TicketContextPanel in session runners when ticket is linked
ProceduralNavigationPage renders panel in left sidebar below step checklist.
TreeNavigationPage renders panel above breadcrumb trail. Both use
useTicketContext hook and show panel only when psa_ticket_id is set.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add fallback_steps to TypeScript types (Task 15)
Add optional fallback_steps field to ProceduralStep interface.
Add FallbackStepRecord interface and fallback_decisions field to Session.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add backend validation for fallback steps (Task 16)
Validate fallback_steps in procedural flow validation: required fields,
no nested fallback_steps, no duplicate IDs. Add FallbackStepRecord schema
and fallback_decisions field to SessionResponse.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: create FallbackSteps UI component (Task 17)
Collapsible component supporting edit and execute modes. Edit mode
provides title/description inputs with add/remove controls. Execute
mode shows "This worked" / "Didn't help" action buttons with emerald/
rose styling. Amber accent styling throughout.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: integrate FallbackSteps into editor and session runner (Task 18)
Wire FallbackSteps edit mode into StepEditor for procedure_step type
with add/remove/update handlers using crypto.randomUUID(). Add execute
mode rendering in ProceduralNavigationPage with fallbackDecisions state
tracking per parent step.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add session-to-flow request/response schemas (Task 19)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add session-to-flow AI generation service (Task 20)
Converts completed troubleshooting sessions into reusable procedural flows
with fallback branches. Includes PSA ticket context integration and
AI-generated step validation.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add POST /ai/session-to-flow endpoint (Task 21)
Converts a completed session into a reusable procedural flow using AI.
Includes quota checking, usage recording, and proper error handling.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add Create Flow from Session button to session detail page (Task 22)
Adds sessionToFlow API client, exports from api/index.ts, and integrates
a prominent "Create Flow from Session" button on SessionDetailPage for
completed sessions. Generates a procedural flow via AI then navigates
to the procedural editor.

* fix: cast tree_type to TreeType in session-to-flow creation
Fixes build error where string was not assignable to TreeType.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: update Playwright test selectors to match actual UI
- Use Control+k instead of Meta+k (Linux/CI compatibility)
- Use 'AI Assistant' group label instead of 'FlowPilot AI'
- Match actual FlowPilot chat page elements (Start a Conversation, New Chat, textarea)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: update Playwright test selectors to match actual UI
- Use specific command palette placeholder to avoid ambiguous matches
- Fix 'Quick Actions' scoping (two elements with same text)
- Fix 'Resolved' exact match on session detail page
- Fix tree editor to use getByText instead of getByDisplayValue
- Fix 'Add Step' strict mode by using .first()
- Fix fallback description placeholder text
- Update playwright.config.ts to use port 5433 and resolutionflow DB
- Update FlowPilot chat selectors to match actual page layout
11/17 new tests now passing. Remaining 6 need procedural session
navigation investigation.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: resolve all Playwright test failures — 16/16 passing
- Fix procedural session tests: sessions auto-start, no Start button
- Fix strict mode violations: use getByRole('heading') for step titles
- Fix FlowPilot chat: use button role selector for New Chat
- Fix command palette page nav: scope Analytics click to palette modal
- Fix fallback runner: remove non-existent Start button click
- Update playwright.config to port 5433 for local Docker

* docs: add sidebar redesign spec and implementation plan
Design spec covers: activity zone with daily stats + session feed,
nav grouping (Resolve/Build/Insights), AI split (FlowPilot + Flow Assist),
pinned flows removal. Implementation plan has 5 chunks, 12 tasks, 39 steps.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add sidebar API client, stats bar, activity feed components
New components: SidebarStatsBar, SidebarActivityFeed, ActivityItem.
New API client for sidebar stats endpoint. Pulse-dot CSS animation.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: restructure sidebar with stats bar, activity feed, and grouped nav
Dashboard-first layout with Resolve/Build/Insights groups.
AI split: FlowPilot (Resolve) + Flow Assist (Build).
Stats bar: Resolved/Active/In Session daily counters.
Activity feed: active sessions with CW ticket #, recent completions.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* refactor: remove pinned flows frontend (PinnedFlowsSection, store, API, pin buttons)
Removed: PinnedFlowsSection component, pinnedFlowsStore, pinnedFlows API client.
Cleaned: pin buttons from TreeGridView, TreeListView, TreeTableView.
Cleaned: favorites section from QuickStartPage, pin props from TreeLibraryPage.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: add FlowAssistPage placeholder and /flow-assist route
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: real-time sidebar stats via session-changed events
Sidebar now refreshes stats when sessions are created or completed,
not just on page navigation. Uses window event bus pattern (same as
folder-changed events in codebase).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat: live-ticking In Session timer using active session start times
SidebarStatsBar now computes active session elapsed time client-side
from started_at timestamps, ticking every 60s. Backend only returns
completed session minutes to avoid double-counting.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: sidebar In Session timer ticks every second and shows seconds
Timer now uses 1s interval (not 60s) and displays seconds when under
a minute so it matches the session timer in the flow UI.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* chore: trigger PR environment redeploy
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* debug: add console.log to SidebarStatsBar for timer investigation
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: parse sidebar timestamps as UTC (append Z suffix)
Backend returns naive UTC timestamps without timezone indicator.
JS Date() treats bare ISO strings as local time, causing the timer
to compute negative elapsed time (future timestamps). Appending 'Z'
forces UTC parsing.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: rename 'In Session' to 'Total Time' for clarity
Makes it clear the timer is an aggregate of all sessions today,
not just the current one.

The StaggerList wrapper creates per-item stacking contexts via CSS animation,
causing the absolute-positioned close popover to render behind sibling cards.
Replace StaggerList with inline stagger-item rendering so we can apply z-50

popover is open so it renders above sibling cards
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add ability to close active sessions directly from the Session History
