Mounts on Pro routers (trees, sessions, scripts, FlowPilot, etc.) and
returns 402 with structured detail when an account's subscription is
missing or locked. Allowlist bypasses billing/account/auth flows so
users can recover from a lapsed subscription.
Conftest now seeds a default Pro/active Subscription on test_user and
test_admin (delete-then-insert because the register endpoint already
creates a free/active sub by default). Two existing tests adapted to
the new seeded plan; tenant-isolation tests seed Subscription rows for
the accounts they create directly.

- Page-level Resolve patches applied_pending → applied_success before
opening the resolution flow, so resolved sessions don't carry a
provisional pending fix.
- Page-level Escalate intercept now catches applied_pending in addition
to verifying/partial; intercept copy generalized from "Verifying state"
to "still needs an outcome."
- PendingBanner gains a Dismiss action, matching the PR body and the
backend's allowed pending → dismissed transition.
- resolution_note_generator and escalation_package_generator system
prompts no longer include real-looking pending examples (anti-parrot
guardrail compliance).
Verified via Docker: prompt anti-parrot 2/2, suggested-fix outcome suite
21/21, frontend tsc -b clean, npm run build clean.

Engineer applies a fix but can't verify yet (waiting on client power-cycle,
AD replication, async sync). Today the verifying banner forces a synchronous
verdict (worked / didn't / partial) — anything else means leaving the banner
stale or guessing wrong. This adds a fourth outcome that parks the fix in a
non-terminal "Awaiting verification" state with a reason ("waiting on what?")
and exposes it on the chat-anchored banner so the engineer doesn't lose track.
Backend
- New non-terminal status `applied_pending` parallel to `applied_partial`.
- New `pending_reason` column (nullable Text) — the "what are you waiting on?"
prose, mirrors `partial_notes`. Required when outcome=applied_pending.
- Outcome endpoint allows pending in/out transitions; pending stamps
applied_at but NOT verified_at (it's parked, not verified).
- Resolution-note + escalation-package prompts handle the new status:
resolution note frames the fix as provisional; escalation package surfaces
pending verification as the leading hypothesis with reference to what's
being waited on.
- Migration: add column + extend status CHECK constraint.
Frontend
- New `BannerMode = 'pending'` + `PendingBanner` component (info-tone,
parallel to PartialBanner) with worked / didn't / update-reason actions.
- VerifyingBanner overflow menu adds "Waiting to verify…".
- Nudge banner's "Still checking" button now actually records pending with
a reason, instead of just silencing for the session.
- AssistantChatPage banner-mode derivation maps applied_pending → 'pending'.
Tests: 4 new integration tests covering pending notes requirement, reason
storage + applied_at/verified_at semantics, pending→success transition,
and pending_reason update on re-PATCH.

Codex review pass on the escalation wedge. Reworks claim_session from
read-then-write to a conditional UPDATE so two seniors racing can't both
win, blocks the original engineer from claiming their own handoff, and
filters self-escalated sessions out of the dashboard escalation queue.
Also preassigns the handoff UUID before flush so the compatibility
escalation_package payload carries it. Removes legacy frontend pickup
state (claiming, handleStartHere) that broke tsc --noEmit.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
unified_chat_service.send_chat_message checked AISession.user_id == user_id,
blocking the senior who claimed an escalation from sending the AI briefing.
Now also allows AISession.escalated_to_id == user_id (the claimer).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Bundles four fixes from the live debugging session:
1. AssistantChatPage: replace urlSessionId === activeChatId gate with a
loadedChatIdsRef. After 8914391 made activeChatId initialize from
urlSessionId, the gate short-circuited fresh mounts and selectChat
never fired. Symptom: senior picks up an escalation, lands on a blank
chat surface with no conversation history and no sidebar entry. Fix
also adds loadChats() in handleStartHere so the picked-up session
appears in the sidebar (its escalated_to_id is null pre-claim, so
listSessions doesn't return it until claim_session sets it).
2. config: bump ESCALATION_AI_ASSESSMENT_TIMEOUT_SECONDS 15s → 45s.
Sonnet was hitting tail latency at 15s in the field, leaving the
magic-moment placeholder permanent. Background-task architecture
(e8ba74e) means this no longer blocks the user; it's just the budget
before publishing has_assessment=false. NOTE: live test still shows
assessment not populating — see HANDOFF for the consolidation plan
that supersedes this.
3. Enter-to-submit: chat-input convention (Enter submits, Shift+Enter
inserts newline) on the escalate-flow forms. RichTextInput gains an
optional onSubmit prop; EscalateModal wires it to handleSubmit;
ConcludeSessionModal gets the same handler on its plain textarea.
4. PendingEscalations: each row is now expandable. Click row body to
reveal the engineer's escalation reason, step count on record,
confidence tier, and PSA ticket number. Pick Up still clicks through
directly. Single-expand-at-a-time keeps the dashboard compact.

Four items from the design-plan audit, all flagged as locked-design or
Codex corrections, shipped together so the GTM demo path covers them
end-to-end before bug bash.
1. Live AI assessment refresh on the magic-moment screen. Backend already
publishes handoff_assessment_ready when enrich_escalation_async commits;
wire the frontend listener so the senior sees the assessment populate
without a manual reopen. New event type + onAssessmentReady handler on
streamEscalations; AssistantChatPage opens a scoped SSE subscription
whenever it tracks a handoff missing its assessment, refetches on match,
and replaces magicHandoff / overlayHandoff in place. Closes the loop on
the async-assessment commit e8ba74e.
2. Suggested-step chips below the chat input. Locked design from the plan
(Codex correction). Chip strip renders above the composer post-claim
when ai_assessment_data.suggested_steps[] is non-empty. Click prefills
the input and focuses; first send or explicit X hides for the session.
3. Unread 6px dot on EscalationQueue cards. localStorage-persisted seen
set (rf-escalation-seen, capped 200). Dot top-right when not seen.
Cleared on open (card click) or claim (Pick Up) — NOT on hover, per
Codex correction. Pick Up stops propagation so it doesn't double-fire.
4. Race-condition toast on claim conflict. The /claim endpoint previously
silently overwrote claimed_by — both seniors thought they owned the
session. New HandoffAlreadyClaimedError carries the winner's id/name/
timestamp; claim_session rejects different-user re-claims (same-user is
idempotent for double-click safety); endpoint returns 409 with
structured detail. AssistantChatPage.handleStartHere extracts and
surfaces "Already claimed by {name} {time_ago}." via toast, drops
?pickup=true, dismisses magic-moment so the loser flows back to queue.
Tests: 2 new unit tests in test_handoff_manager.py (conflict raises,
same-user idempotent). Full handoff + escalation suite (34 tests) green.
Frontend tsc -b clean.

Three improvements driven by live wedge testing.
1) Notification title now includes a problem snippet and PSA ticket
suffix when present:
"Escalation from Jane · #12345: Outlook is failing to sync email…"
Replaces the prior "Session escalated by Jane" copy that made every
escalation from the same junior look identical in the bell panel.
Snippet is trimmed to 70 chars with ellipsis. handoff_manager now
passes psa_ticket_id through in the notify() payload so this works
for both /escalate and /handoff entry points.
2) AI enrichment (assessment + enhanced escalation_package) moved to
a FastAPI BackgroundTask. The escalating engineer no longer waits
on 15-25s of Sonnet latency — handoff creation returns as soon as
snapshot, status flip, dual-write, documentation, PSA push, and
notify() are committed. enrich_escalation_async opens its own DB
session, runs both AI calls, updates handoff.ai_assessment +
session.escalation_package, commits, and publishes a new
`handoff_assessment_ready` event on the escalation bus. Frontend
doesn't yet listen for that event — the magic-moment screen still
shows a placeholder ("AI assessment is still generating. Reopen
this view in a few seconds…") which is honest about the state.
Live polling / auto-refresh on the bus event is the natural next
step.
3) ChatSidebar entries now surface the problem summary as a secondary
line and tag PSA-linked sessions with a monospace #ticket badge plus
an "Escalated" pill on in-transit sessions. ChatListItem grew
problem_summary, psa_ticket_id, and status fields; loadChats
populates them from listSessions. The user couldn't tell their own
sessions apart in the sidebar because they all rendered as "New
Chat" with no distinguishing detail — this fixes that for any
session, escalated or not.
Test plan
- Backend full suite: 1103 passed in 255.85s with -n auto.
- Frontend tsc -b clean.

Two field-reported issues from live wedge testing.
ESCALATION_AI_ASSESSMENT_TIMEOUT_SECONDS bumped 5s → 15s. The 5s bound
fired too aggressively against the Sonnet diagnostic assessment prompt;
~4-8s is typical but tail latency hits 12-14s. The fallback "Assessment
unavailable — model didn't respond in time" placeholder was showing on
the magic-moment screen for two consecutive escalations, which kills
the demo. 15s keeps the click-path bounded but lets the typical case
return real content. Real fix is async generation (kick off, persist
when done, surface "still computing" with refresh) — captured as a
follow-up; bumping the bound is the right call for the wedge demo.
list_sessions now matches escalated_to_id == current_user.id alongside
the existing user_id and escalation_package.picked_up_by clauses. The
unified HandoffManager.claim_session sets escalated_to_id but doesn't
write the legacy picked_up_by JSONB key, so picked-up sessions never
showed in the senior's chat list — the senior would land on the
session detail (active chat) but the sidebar showed only their other
unrelated sessions. User reported this as "4 different versions of the
session in the chat history section" — they were actually 4 unrelated
empty sessions the senior owned, plus the picked-up session was just
invisible. Backend tests still 94/94.

Replaces the legacy flowpilot_engine.escalate_session orchestration with
a single canonical path through HandoffManager. Every escalation now
creates a SessionHandoff row, fans out via the SSE bus, persists
AppNotification rows for the bell icon, dispatches to external channels
(Slack/Teams) via notify(), and emails per-user — regardless of whether
the call entered through /escalate (legacy URL) or /handoff (new URL).
The senior-pickup magic-moment screen now works end-to-end from the
EscalateModal bell-icon path the user just tested.
Backend
- HandoffCreateRequest gains optional target_user_id (the equivalent of
the legacy escalated_to_id field). Self-targeting rejected.
- HandoffManager.create_handoff handles intent='escalate' end-to-end:
sets escalation_reason + escalated_to_id, builds the legacy enhanced
AI escalation_package (Sonnet, lazy-imported from flowpilot_engine,
graceful fallback on failure), and merges handoff metadata into it.
Eager-loads session.steps and session.user via selectinload — required
by both the enhanced-package builder and notify() to avoid
MissingGreenlet on async lazy access.
- HandoffManager.finalize_escalation generates SessionDocumentation,
pushes documentation to PSA, and runs notify() — pre-commit so the
AppNotification rows persist atomically with the handoff.
- HandoffManager.dispatch_escalation_notifications keeps only the
fire-and-forget IO (bus publish, per-user emails) — runs post-commit.
Pulls engineer name via a separate User query rather than relying on
session.user lazy access.
- /handoff endpoint passes target_user_id through and calls
finalize_escalation pre-commit.
- /escalate endpoint is now a thin shim: owner-only session lookup,
HandoffManager.create_handoff(intent='escalate'), finalize_escalation,
commit, dispatch_escalation_notifications, return SessionCloseResponse
built from documentation + psa_result. flowpilot_engine.escalate_session
is no longer called by any endpoint.
- pickup_session accepts both 'requesting_escalation' (legacy in-flight
sessions) and 'escalated' (new canonical) so the migration is seamless
for sessions already in the queue.
- Escalation queue list and sidebar count now match either status.
Frontend
- useFlowPilotSession optimistic update flips status to 'escalated'
instead of 'requesting_escalation' so the page state matches the
unified backend response.
Verified end-to-end live: a fresh /escalate call from the junior produces
status='escalated', a SessionHandoff row, a SessionDocumentation, PSA
push attempted (no_psa for this test session), AND a bell-icon
AppNotification for the team admin with link
/pilot/{session_id}?pickup=true. Backend test suite: 1103 passed.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Two backend changes that unbreak the senior-pickup path from the
notification panel:
1. notification_service: session.escalated link template now ends with
?pickup=true so the senior lands in the handoff/pickup flow on
click. Without it, navigation hit /pilot/:id directly, which then
404'd on the GET because the senior isn't yet escalated_to_id —
the user perceives this as the bell-icon "just clearing the
notification".
2. ai_sessions GET access: any account member can now read an escalated
session's detail when status is requesting_escalation or escalated.
The owner-only guard was overly restrictive for explicitly-shared
in-transit states. Tenant boundary is enforced by RLS on the
underlying query, so account-scope is the right ceiling here. After
pickup, the existing handler/escalated_to_id checks still apply.
Verified live: re-login as the senior engineer and GET the active
escalated session — now returns 200 with full detail. Focused test
subset plus tests/test_sessions.py and tests/test_session_sharing.py
→ 94 passed in 43.26s, no regressions.

First half of the WebSocket/SSE push slice. Paused mid-flight to hand
the branch to Codex for outside-voice review before stacking more
commits on top. See .ai/HANDOFF.md for the full pause context + what
to look at.
What's here:
- backend/app/core/escalation_bus.py — module-level singleton in-memory
pub/sub keyed by account_id. asyncio.Queue per subscriber with
64-event maxsize and drop-on-full semantics. Designed to be swappable
for Redis pub/sub when Railway scales past single-replica.
- backend/app/api/endpoints/session_handoffs.py — GET
/api/v1/ai-sessions/escalations/stream SSE endpoint. Auth via
require_engineer_or_admin. 25s heartbeat. Account-scoped subscribe
bound to current_user.account_id.
- backend/app/services/handoff_manager.py — dispatch_escalation_notifications
now publishes a `handoff_created` event to the bus BEFORE the email
fan-out, in a try/except so a bus failure can't block email delivery.
- backend/tests/test_escalation_bus.py — 7 unit tests, all green
standalone (0.14s). Cross-tenant isolation, drop-on-full, no-subscribers.
- backend/tests/test_handoff_manager.py — +1 dispatcher integration test
(publishes to bus, payload shape).
- backend/tests/test_session_handoffs_api.py — +2 endpoint tests (viewer
blocked, ready event handshake).
[gstack-context]
Decisions:
- SSE over WebSocket (one-way, browser EventSource semantics, fewer
moving parts behind Railway proxy)
- In-memory bus over Redis for v1 pilot (3 MSPs, single replica)
- Drop-on-full subscriber queue rather than back-pressure publishers
- Bus publish ahead of email send, both wrapped in try/except so
neither can break handoff creation
- Frontend will be a fetch-based ReadableStream reader matching the
existing streamDocumentation pattern, not native EventSource
(custom-header auth)
Remaining (post-Codex):
- Frontend SSE subscription in EscalationQueue.tsx (slide-in,
reconnect, tab-title flash, prefers-reduced-motion)
- Magic-moment handoff-context screen
- Re-run the full backend test suite to verify the SSE +
dispatcher integration tests (bus units already green standalone)
Tried:
- Running the full test suite repeatedly without xdist; the per-test
DROP SCHEMA + recreate fixture made wall-clock prohibitive when
multiple stale runs collided on the same Postgres test schema.
Resolution: -n auto next time.

First half of the Escalation Mode notification dual-path. WebSocket/SSE
push is the second half (next commit) — email handles offline seniors,
push handles online ones for the magic-moment demo.
HandoffManager.dispatch_escalation_notifications:
- Pulls active engineer/admin/owner-role users in the same account_id
(excludes the escalator + viewers + soft-deleted)
- Sends via existing EmailService.send_notification_email, concurrent
via asyncio.gather; per-message failures don't block the rest
- Wrapped in try/except: any exception is logged + swallowed. Handoff
creation is authoritative; notification is advisory. This is the
graceful-degradation regression both eng + codex reviews flagged as
critical (handoff must succeed even if SMTP is down).
Endpoint wiring (POST /ai-sessions/{id}/handoff):
- Dispatch fires AFTER db.commit() — never email about a rolled-back
handoff. Trust-erosion bug if we got that wrong.
- Only fires for intent=escalate. Park is private to the escalator.
Tests (4 new):
- emails-engineer-recipients-in-account: viewer excluded, escalator
excluded, only the engineer/admin teammates get the message
- skipped-for-park-intent: park doesn't fan out
- graceful-degradation-when-email-raises: RuntimeError from the email
service does NOT bubble out of dispatch
- endpoint-dispatches-on-escalate: end-to-end wiring through POST
Per-channel delivery records (replacing the dead `notification_sent`
boolean per Codex correction) is a v1.x story — for now application
logs are the audit trail. See
docs/plans/2026-04-27-escalation-mode-wedge-design.md.
20 tests green across handoff_manager + session_handoffs_api +
flowpilot_analytics_escalations. No regressions.

POST /ai-sessions/{id}/handoffs/{hid}/claim previously required only an
authenticated user, so a viewer-role account user could claim escalations.
Codex review flagged this as wedge-relevant: the Escalation Mode race-
condition story (two seniors clicking Pick Up simultaneously) depends on
auth gating for audit integrity. Originally captured as a deferred TODO
during /plan-eng-review, then moved in-scope by /codex review.
Swap the dep to require_engineer_or_admin. One-line change. Two new tests:
- viewer_role gets 403 with "Engineer or admin access required"
- engineer/owner role still succeeds and claimed_at + claimed_by populate
Existing handoff create + queue tests unaffected.

GET /api/v1/analytics/flowpilot/escalations?period={7d,30d,90d}
Computes the in-product wedge metric for Escalation Mode: average / median /
p95 seconds between SessionHandoff.claimed_at and the first ai_session_step
created on the same session after that timestamp. Account-scoped, role-gated
to engineer-or-admin.
The metric is intentionally NOT called "minutes recovered" — that's the
two-metric framing locked by /codex review: this in-product number must be
paired with manual baseline (the verbal-handoff stopwatch from The Assignment)
to produce the savings claim. Schema's `metric_definition` field surfaces the
disclaimer in every response so callers don't oversell it.
Implementation notes:
- Uses correlated scalar subquery for first-step-after-claim per handoff,
aggregates avg/median/p95 in Python (~1k rows/account/month is well within
budget; cleaner than percentile_cont gymnastics in SQL)
- Excludes unclaimed handoffs (claimed_at IS NULL)
- Counts claimed-but-no-action handoffs in n_handoffs_claimed but not in
n_handoffs_with_action — surfaces the conversion-rate signal
- Floors negative deltas at 0 to handle clock-drift edge cases
Tests cover happy path, zero-data, claimed-but-no-action accounting, period
window filtering, multi-handoff aggregation, multi-tenant isolation (Phase 4
RLS landmine pattern), viewer-role 403 gate, and period validation. 9 tests,
all green. No regressions in existing handoff_manager / session_handoffs
suites.
First piece of the Approach A wedge build per
docs/plans/2026-04-27-escalation-mode-wedge-design.md. Unblocks the queue
stat-card and the analytics page.

Brings in PR #141 (PSA ticket management) so FlowPilot can ship on top
of a unified main. Two manual conflict resolutions:
1. CLAUDE.md — kept the FlowPilot ai-handoff rewrite (`.ai/`-driven
protocol). The pre-rewrite reference content (CW integration notes,
lessons archive, env vars table) lives in `docs/connectwise/`,
`docs/LESSONS-ARCHIVE.md`, and DEV-ENV.md by design.
2. frontend/src/pages/AssistantChatPage.tsx — both conflict regions
were purely additive. Concatenated FlowPilot's Phase 2-9 state hooks
(facts, activeFix, preview*, scriptPanelOpen, templatizeQueue) with
PSA's spin-off ticket state (linkedTicket, showNewTicket, spinOffHint).
Both modal mounts (TemplatizePrompt, ShortcutsHelpOverlay,
NewTicketModal) kept. All setters wired by either branch are intact.
Verification:
- `tsc -b` clean across the merged tree.
- Browser smoke-test (Session B fixture): Phase 9 ProposalBanner
("Run AI-drafted PowerShell to recover SSL VPN") renders alongside
PSA's new Tickets sidebar icon. Console clean.

Called by the inline Script Builder tab on Submit. Writes
ai_drafted_script + ai_drafted_parameters to the fix without stamping
applied_at (a draft is not an application — that's §5 of the Phase 9

POST /script-builder/sessions now supports origin='pilot_inline':
- Requires ai_session_id; validates it against current user ownership.
- Get-or-create: returns existing row for (user, ai_session_id) pair.
- Partial unique index on the DB backs the invariant; races resolve to
the single winner row.
list_sessions + count_user_sessions default-scope to origin='standalone'
so inline scratch sessions don't pollute the /script-builder dashboard
or count against the 5-session cap.

Issue #3 from phase-8-review-issues.md. 'Not yet' on the AI-confirming
banner was a local-state hide; the proposal re-surfaced on the next
refreshSessionDerived call.
Two-part fix:
- PATCH /outcome now clears ai_outcome_proposal on any terminal action
(engineer has taken a decision; stale AI proposal is moot).
- New DELETE /ai-sessions/:sid/suggested-fixes/:fid/ai-outcome-proposal
endpoint for explicit 'Not yet' rejection. Does not touch status
or state_version — pure UI state.
Frontend handleRejectAIProposal now calls the DELETE and setActiveFix
with the server response.

Issue #2 from phase-8-review-issues.md. Apply was client-side-only via
a bannerApplied flag. Refresh / chat reselect / multi-tab would drop
Verifying state back to Proposed.
- New POST /ai-sessions/{sid}/suggested-fixes/{fid}/apply stamps
applied_at without changing status (still 'proposed'). Idempotent
if already stamped; 409 if fix is past proposed (a terminal outcome
was already recorded).
- Bumps state_version so resolve/escalate preview bundles reflect that
the fix has entered verifying.
- Frontend handleApplyFix calls the endpoint and uses the returned
applied_at directly. bannerApplied client flag is removed.

Issue #1 from phase-8-review-issues.md. Cache invalidation alone isn't
enough — previews were also omitting outcome fields from the LLM bundle,
so a fresh regenerate still couldn't distinguish proposed / failed /
partial / success.
- PATCH /outcome now bumps ai_sessions.state_version (matches
record_decision's existing pattern).
- Resolution-note + escalation-package bundles now include status,
applied_at, verified_at, partial_notes, failure_reason on the active fix.
- Generator prompts prescribe outcome-aware phrasing (closure language
for success; what-we've-tried + next-steps for failed/partial).
- New end-to-end test asserts the regenerated preview reflects the
recorded outcome, not just that the cache key changed.

Tells the AI when + how to emit the [FIX_OUTCOME] marker that Task 4's
parser consumes. Placeholder-only per the anti-parrot pattern — no
literal UUIDs, outcomes, or reasons that could leak into unrelated
sessions.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The AI emits [FIX_OUTCOME] when the engineer indicates in chat that a
prior suggested fix worked, didn't work, or was partially applied. The
marker writes to session_suggested_fixes.ai_outcome_proposal (JSONB),
which the frontend surfaces as a "confirm outcome?" banner. The status
column is only updated when the engineer clicks confirm (via PATCH
/outcome endpoint from Task 3).
Placeholder-only system prompt wiring comes in Task 5.
