WDP hardening: sticky-v2 EnrollmentType + DevicePreparation downgrade guards

Two low-risk fixes ahead of the first live Device Preparation enrollment:

- StoreSessionAsync: EnrollmentType is now sticky-v2 across re-registration
  (same contract as the sticky-true booleans) so a degraded AutopilotSettings
  read after a reboot can no longer flip an observed v2 session back to v1.
- EnrollmentScenarioProfileUpdater: ImeUserSessionCompleted,
  SelfDeployingDeadlineConfirmed and WhiteGloveSealingConfirmed no longer
  overwrite an established DevicePreparation profile (seeded at Medium from
  the registry-deterministic v2 fact).

+# App Version Duration Regression Radar
+
+Detects "version X made this app's installs much slower" — the concrete, quotable insight
+("median install duration rose from 11 to 29 min after version X") — from the per-(session,
+app) `AppInstallSummaries` rows. Duration only: failure-rate per version is already visible
+in the apps dashboard's `versionBreakdown`, and rate regressions belong to Wilson-interval
+statistics, not medians.
+
+# Schema
+
+## Signal & detection
+
+Per (tenant, app), the MEASURED install population is: `Status == "Succeeded"`, terminal
+state not Skipped/Postponed, `MetricsMath.HasMeasuredDuration` (1s..6h — 0s means the start
+was unobserved, above 6h means back-stamped batches), no `AppIdCollision`, non-empty
+`AppVersion`. Versions are ordered by FIRST-SEEN install time (min `StartedAt`), never by
+string comparison ("9.1" vs "2024.10" would lie). The comparison pair is always the newest
+version (the one with the most recent measured install) vs. the version with the latest
+first-seen strictly before it.
+
+MEDIANS, not means (nearest-rank, shared with the apps dashboard via
+`AppsAnalyticsHelper.Percentile`) — one back-stamped straggler must not fire a fleet alert.
+A regression fires only when ALL hold over the trailing 35-day horizon:
+
+1. both versions have ≥ 10 measured installs;
+2. current median ≥ 2× the previous version's median;
+3. absolute increase ≥ 300 s (a 20s→45s app is noise, not an incident).
+
+## Suppression & limits
+
+* Parallel ring rollouts can make "previous" a concurrently-deployed version — accepted in
+  v1; the episode key (app, current version) still caps it at one bell per version.
+* Platform kill switch: app setting `AppVersionRegressionRadarDisabled=true` skips the
+  radar (fail-open — it only notifies, never mutates data).
+* One cross-tenant install-summary read per pass (the same query the global apps dashboard
+  runs), grouped by tenant; per-tenant failures are non-fatal.
+
+## Alert episodes (tracker keyspace)
+
+An episode lives as `appversionregression|{app-lower}|{version-lower}` (table-key-sanitized;
+raw AppName/CurrentVersion live in columns, the mapper never parses the RowKey) in the
+notification-tracker table, next to the `ruleregression|` keyspace: the row IS the dedup
+(bell + ops event fire exactly once per episode) and the `versionRegressions[]` payload —
+both medians, both sample counts, lift. Numbers refresh on every radar pass while the
+episode stays active; `FirstNotifiedAt` never moves. The episode closes (dedup re-arms) when
+the alerted version drains under 10 measured installs in the horizon or its recomputed
+median falls back under 1.5× the previous version's median; the tracker's 30-day retention
+sweep also re-arms, so a month-old still-burning regression rings once more by design.
+
+## Notification chain (v1: bell + ops event)
+
+* Tenant bell `app_version_duration_regression` (audience: Admin), href
+  `/apps/detail?name={app}&days=35` (canonical `appDetailUrl` shape). Message carries the
+  full numbers so the admin can verify without a portal round-trip.
+* Ops event `AppVersionDurationRegression` (Tenant category, Warning) — dual-registered in
+  the web `OPS_EVENT_TYPES` catalog so operators can wire Telegram/Teams/Slack alert rules.
+
+## Surfaces
+
+* `apps/{appName}/analytics` (+ global twin with `?tenantId=`) responds with
+  `versionRegressions[]` (empty for the cross-tenant aggregate — episodes are per-tenant
+  rows), and `versionBreakdown[]` rows now carry `measuredInstalls` /
+  `medianDurationSeconds` / `p95DurationSeconds`.
+* Apps detail page: amber "↑ Duration regression" banner above the version cards and a
+  "Median Install Duration by Version" bar chart.
+
+# Examples
+
+A tenant ships Contoso VPN 2.4.0 after 2.3.9. 2.3.9 has 40 measured installs, median 660s;
+2.4.0 accumulates 12 measured installs with median 1740s. Lift 2.6×, absolute +1080s →
+episode `appversionregression|contoso vpn|2.4.0` opens, one bell + one ops event fire.
+Subsequent passes refresh the numbers only. When 2.4.1 replaces 2.4.0 and 2.4.0 drains
+below 10 measured installs in the horizon, the episode deletes and the dedup re-arms.

+description: The enforced completeness nets added by the fragility-audit P5/P6 remediation — table lifecycle buckets, the SessionsIndex field manifest, the single session-scope resolver with its SessionTenantLookup point-read, and the server-side dashboard free-text search.
+resource: backend
+tags: [lifecycle, offboarding, sessionsindex, manifest, scope-resolution, search, performance]
+timestamp: 2026-08-13

+
+# Schema
+
+Four mechanisms replace hand-synchronized copies with a declared source plus tests that fail on drift.
+
+## 1. Table lifecycle buckets
+
+Every table in `Constants.TableNames` must belong to at least one deletion lifecycle:
+
+| Bucket | Mechanism | Source of truth |
+|---|---|---|
+| Tenant-offboarding wipe | `TenantOffboardingHandler` bucket arrays (`TenantPartitionTables`, `CompositePartitionTables`, `DiscriminatorTables`, `PropertyOnlyTables`, `RowKeyTables`, `ArchivedRuleTables`) + the one-off `TenantConfiguration` final delete | handler arrays (read via reflection by the test) |
+| Per-session cascade | `DeletionManifestBuilder.BuildAsync` step list (incl. the Final tombstone → Sessions + SessionsIndex) | a real manifest built against an empty-inventory fake |
+| Kept by design | reviewed exception list with per-table reasons | `TableLifecycleBucketTests.KeptByDesign` |
+
+`TableLifecycleBucketTests` (Functions.Tests) asserts: constants set-equal `TableNames.All`, no table unclassified, kept-by-design disjoint from every wipe path, bucket entries are real constants, offboarding buckets disjoint except documented multi-membership (`BootstrapSessions`).
+
+**Not covered mechanically:** whether a bucket's key shape matches the table's writer. That was the UsageMetrics bug (PK=date, RK=tenantId sat in the exact-PK bucket; the wipe matched 0 rows) — SafeWipe **Variant D** (`WipeByRowKeyAsync`, `RowKey eq '{tenantId}'`) now covers RowKey-anchored tables. Read the writer's `new TableEntity(pk, rk)` before classifying a new table.
+
+## 2. SessionsIndex field manifest
+
+`SessionIndexFieldManifest` (Functions/Services) declares the full-mirror column set: `AlwaysProjected` (32, written with defaults on every rebuild), `ConditionallyProjected` (18, written only when present), `PrimaryOnly` (4 — ServerActions + deletion-CAS fields that never touch the index). `SessionIndexFieldManifestTests` pins `BuildSessionIndexEntity` against it bidirectionally (full-row fixture built from a test-local sample table, NOT from the manifest — deriving the fixture from the manifest would make the check circular), pins that every manifest field influences `MapToSessionSummary`, and pins the rebuild's `TableUpdateMode.Replace` (a merge-mode upsert could never clear a conditional column the primary blanked). `MergeSessionIndexAsync` logs a warning for merged keys outside the manifest (fail-soft drift guard).
+
+## 3. Session scope resolution (one implementation)
+
+`RequestContextExtensions.ResolveSessionScopeAsync(ctx, sessionRepo, sessionId, requireGlobalAdmin)` is the single implementation of the former 15-site copy-paste fallback ("which tenant owns this session?"):
+
+- Non-global callers always keep the middleware-validated `TargetTenantId`.
+- Global-scope callers resolve via `ISessionRepository.ResolveSessionTenantIdAsync` — a point-read on **SessionTenantLookup** (PK=sessionId, RK="tenant") with a legacy cross-partition SessionsIndex scan fallback that self-heals the lookup row, so the scan is paid at most once per pre-table session.
+- `requireGlobalAdmin: true` on WRITE paths gates the cross-tenant reach on `IsGlobalAdmin` so a read-only Global Reader can never steer a write into a foreign tenant.
+- Unknown session → `TargetTenantId`, leaving each endpoint's own not-found semantics (404 / empty 200 / 400) in charge.
+- Delegated (MSP) callers deliberately get NO fallback — extending it to `AllowedTenantIds` is a pending user decision.
+
+The lookup row is written at session registration (fail-soft), deleted by the cascade one step before the tombstone, and rebuildable from Sessions (not in the critical-backup set). The former lazy triggers (`events.Count == 0` → scan) are gone: empty-but-owned results no longer pay a table scan, and endpoints resolve upfront.
+
+Related enforcement added with the migration: `RecomputeTriggerGate` — `?reanalyze=true` and `?rescan=true` on the MemberRead session routes are actions (delete + rewrite stored results) and now 403 for Viewer / Global Reader / cross-tenant tenant roles (Global Admin or own-tenant Admin/Operator only).
+
+## 4. Server-side dashboard search
+
+`q=` on `/api/search/sessions` + `/api/global/search/sessions`: case-insensitive substring over exactly the fields the dashboard's client-side filter searches (device name, serial, manufacturer, model, status, sessionId, geo, agent version, OS fields — NOT the client-derived date/duration/blocked tokens; a server-only field would produce ghost results the client filters back out). Azure Tables has no substring operator, so the scan path backfills whole Azure pages until it has `pageSize` matches (max 10 pages per request, continuation at a page boundary — gap-free). `q` is bound into the pagination fingerprint. The web dashboard's `searchAll()` (useDashboardSessions) follows nextLink up to 10 requests / 50 matches and dedupe-merges results into the loaded list (`mergeSessionsById`), replacing the former `loadAll()` walk that downloaded the entire session history to search it client-side. Delegated callers in cross-tenant mode keep the legacy full sweep (the global search route has no delegated tier).
+
+# Examples
+
+Adding a new table: classify it in one lifecycle path before `TableLifecycleBucketTests` lets it ship — offboarding bucket (check the writer's PK/RK shape first), deletion-manifest step, or `KeptByDesign` with a reason.
+
+Adding a mirrored SessionsIndex field: manifest entry + `BuildSessionIndexEntity` write + `MapToSessionSummary` read + a sample value in the test — any missing step is red.

+`CreatedByUpn`/`CreatedAtUtc` (first writer, immutable across edits), `UpdatedAtUtc`, and
+`RuleIdsJson` — a **snapshot of the rule ids that had fired for the session at write time**
+(from `IRuleRepository.GetRuleResultsAsync`, fail-soft to empty). The snapshot is what turns an
+annotation into a rule-quality label without a join: filtering annotations by `ruleId` + `verdict`
+yields confirmed vs false-positive counts per rule even after results are re-analyzed or deleted.
+
+**Verdict + note are independently optional**; a PUT with both null **deletes** the lane row
+(there is no DELETE route). Author identity is always stamped server-side from the JWT
+(`TenantHelper.GetUserDisplayName` + `RequestContext.UserPrincipalName`) — a body-supplied
+author never wins (same anti-spoof contract as the gather-rule PUT-upserts).
+
+# Authorization
+
+Routes (all in `EndpointAccessPolicyCatalog`):
+
+| Route | Policy | Notes |
+| --- | --- | --- |
+| `GET sessions/{sessionId}/annotations` | `MemberRead` + QueryParam | handler filters the GA lane |
+| `PUT sessions/{sessionId}/annotations/{lane}` | `TenantAdminOrOperator` + QueryParam | re-gated per lane in-function |
+| `GET global/session-annotations` | `GlobalReadOrAdmin` + QueryParam | evaluation stream; delegated ("MSP") readers are rescue-admitted on a managed `?tenantId=` only |
+
+**Per-lane write matrix** (`UpsertSessionAnnotationFunction.IsLaneWritableByCaller`, an
+`internal static` pure function like `QueueSessionActionFunction.IsTypeAllowedForCaller`):
+`operator` → tenant Operator or tenant Admin; `tenantadmin` → tenant Admin; `globaladmin` →
+Global Admin only. **Own-tenant binding:** the session's tenant is resolved *before* the gate
+(GA cross-tenant fallback via `FindSessionTenantIdAsync`), and tenant-role inputs are zeroed
+when the resolved tenant differs from the caller's JWT tenant — so a GA who is also an admin of
+their home tenant can never write another tenant's operator/tenantadmin lanes. Cross-tenant, a
+GA writes exactly the `globaladmin` lane (the platform labeling flow).
+
+**GA lane is platform-internal.** `GetSessionAnnotationsFunction.FilterLanesForCaller` drops the
+`globaladmin` lane for every caller without `HasGlobalScope` (tenant members and delegated
+admins). Both list endpoints enforce the same rule server-side via the repository's
+`excludeGlobalAdminLane` OData clause — on the global route this matters exactly for the
+delegated-rescue path, which reaches it without global scope. Tenant lanes are readable by all
+members of that tenant.
+
+**Audit.** Non-GA writes/clears log `LogAuditEntryAsync(..., "SessionAnnotation",
+"{sessionId}/{lane}", ...)`; GA writes are skipped (platform-internal labeling must not surface
+in the tenant-visible audit log — same convention as GA session-report submissions).
+
+# Lifecycle
+
+* **Per-session cascade delete**: three exact-RK steps (one per lane) in `DeletionManifestBuilder`
+  (orders 17–19; inventory 20/21, tombstone 22). `ComputePreflightCounts` sums repeated-table
+  steps so the `sessionAnnotations` count covers all lanes.
+* **Tenant offboarding**: `SessionAnnotations` is in the PK=tenantId wipe list — deliberately
+  wiped, unlike `Feedback` (annotations are customer session data, not product feedback).
+* **Backup**: member of `Constants.CriticalBackupTables.All` — hand-labeled data is the most
+  expensive data on the platform to lose.
+* Being in `Constants.TableNames.All` auto-creates the table at startup and exposes it to the
+  raw `list_tables`/`query_table` tools.
+
+# Surfaces
+
+* **Portal**: `SessionAnnotationsCard` on the session detail page (`#section-annotations`, after
+  Analysis; registered in BOTH the section div and the `sessionSections` sidebar registry). The
+  card mirrors the matrix via the pure module `sessionAnnotationLogic.ts` (vitest-pinned) and
+  uses the explicit-Save pattern; the backend re-gates every save. Collapsed by default with a
+  count + verdict-pill summary header.
+* **Portal overview page** `/annotations` (Monitoring sidebar group — deliberately NO new
+  "Insights" group; Fleet Health & co. are insights too and a second analytics group would
+  dilute both): tenant-scoped list backed by `GET sessions/annotations/list`
+  (`ListTenantSessionAnnotationsFunction`, MemberRead + QueryParam). The path sits under the
+  `/api/sessions` client-cert exclusion prefix (rename-over-exclusion convention; the Azure
+  exclusion list is portal-only config) and uses THREE segments because a two-segment literal
+  would be eaten by the `sessions/{sessionId}` route template. The tenant is always the
+  middleware-validated `TargetTenantId`, and for callers without global scope the repository
+  adds a server-side `Lane ne 'globaladmin'` OData clause — hidden rows never consume page
+  budget, and an explicit lane=globaladmin filter self-contradicts to an empty page. Rows
+  deep-link to `sessions?id=…#section-annotations`. The page carries the standard tenant
+  switcher (`useAggregatedAdminScope` + `TenantScopeSelector`): a GA/Reader defaults to the
+  "All tenants" aggregate (the portal twin of MCP's `list_session_annotations`) with per-tenant
+  drill-down, a delegated ("MSP") admin gets the managed subset; cross-tenant scopes route to
+  `GET global/session-annotations`, a tenant column appears, and deep links carry the row's
+  `tenantId`.
+* **MCP read**: `get_session_summary` carries an `annotations` key (4th parallel leg, fail-soft
+  null); `list_session_annotations` (`ga`-gated) is the evaluation stream with `tenantId / lane /
+  verdict / ruleId / dateFrom / dateTo` filters and nextLink pagination. The `ruleId` filter is
+  applied server-side but client-of-Azure (substring on the JSON column), so the backend
+  back-fills short pages by looping the Azure continuation (bounded rounds) — filtered-out rows
+  never consume page budget.
+* **MCP write**: `annotate_session` (`strictGa`-gated, MUTATING) always PUTs the `globaladmin`
+  lane — no lane argument by design. This is the frictionless labeling path after a session-debug.
+* **Session reports**: `SessionReportService.SubmitReportAsync` snapshots ALL lanes into
+  `annotations.json` inside the report ZIP (`annotationCount` in report-metadata.json; fail-soft).
+  Safe because report blobs are readable only through the GA-only session-reports routes, and
+  valuable because the ZIP outlives the session's retention/delete.

+# Drift Guards
+
+Follow-up to the 2026-08 fragility audit (see [Lifecycle Manifests & Session Scope
+Resolution](backend/lifecycle-manifests-and-session-scope.md) for the earlier rounds).
+Each section below replaces a hand-synchronized mirror with an enforced contract: a
+change on one side now fails a build, a type check, or a test on the other side.
+
+# Schema
+
+## SignalR message names — one catalog, typed on both ends
+
+`Constants.SignalRMessages` (Shared) is the complete catalog of SignalR target names.
+Backend senders (output bindings and the imperative `SignalRNotificationService`)
+reference the constants; the hub name is `SignalRGroupHelper.HubName`. The catalog is
+exported into `shared-manifests.json` (`signalRMessages` section) by
+`SharedManifestParityTests`, and the web's `SignalRContext.on/off` type their event
+name against the generated union (`lib/signalrMessages.ts`) — subscribing to a name
+the backend never sends is a tsc error, not a silent no-op. `newevents` is the one
+legacy lowercase name; it is a persisted wire name, do not "fix" the casing.
+
+## Inverted-tick RowKeys — one codec
+
+`RowKeyCodec` (Functions/Helpers) is the single encoder/decoder for
+`rev(t) = MaxTicks - t.Ticks` RowKeys. Every writer routes through it; the persisted
+per-table shapes (D19 standard, AuditLogs `!`-prefix, UserActivity's legacy D20 width,
+ConfigurationBackups' 28-char truncation) are pinned by `RowKeyCodecTests` and must
+never change — a width/prefix change reorders live tables against their existing rows.
+`BusinessTimestamp` keeps the OData clause builders and delegates decode to the codec.
+
+## Tombstone rows carry their table
+
+`DeletionRowDump.Table` names the source table on FINAL (Tombstone) rows — the one
+step that mixes two tables while `DeletionStep.Table` is null.
+`DeletionTombstoneTables.Resolve` is the only consumer-side resolution (delete +
+restore + dry-run); the historical `Contains('_')` RowKey-shape heuristic survives
+solely as the fallback for manifests written before the field existed and must outlive
+one full manifest-retention cycle.
+
+## Anonymous OkAsync responses — frozen, shrink-only
+
+`OkAsyncBaselineGuardTests` freezes the 44 existing `req.OkAsync(new { … })` call
+sites as a per-file baseline. A new anonymous response (new file or count above
+baseline) fails; converting a site to a typed DTO (Shared response models, picked up
+by the manifest parity tests) fails too until its baseline entry is lowered — the debt
+list stays truthful and only ever shrinks.
+
+## Tenant settings — per-section PATCH
+
+The web's Settings sections no longer PUT the full ~92-field configuration. Each
+section's exact write surface lives in `app/settings/sectionFieldMap.ts` (owned fields
+plus documented `alsoWrites` write-throughs); `saveConfiguration` diffs those fields
+against the loaded config and PATCHes only the changes through
+`PATCH config/{tenantId}/fields` — the transactional endpoint (CAS + fail-closed
+backup + exactly-these-fields verify + auto-rollback) that previously served MCP only.
+The policy line is TenantAdminOrGA; a tenant admin runs on the stricter
+`TenantConfigCallerTier.TenantAdmin` whose deny-list turns GA-only fields into
+explicit 400s. Deploy order: backend before web. `sectionFieldMap.test.ts` pins
+field↔section ownership (each field exactly one owner, all fields on the model, none
+server-denied); backups/revert stay GlobalAdminOnly.
+
+## Scoped endpoint routing — one decision object
+
+`lib/scopedApi.ts` owns the tenant/global endpoint-pair choice: pages pass their scope
+hook object (`routeGlobal`, `selectedTenantId`, `effectiveTenantId`) instead of
+hand-rolling `routeGlobal ? global(..., sel || undefined) : tenant(tid, ...)` with the
+tenant parameter at a different position per pair. `useGlobalAdminScope` is now a thin
+projection over `useAggregatedAdminScope` (one hook, aggregated as a mode) via the
+pure `resolveConcreteScopeView`. `lib/scopedFetch.ts` adds the shared JSON+ok-check
+fetch layer. `lib/navVisibility.ts` extracts the sidebar's roles × nav-config × guard
+logic; its matrix test also ratchets the known "sidebar shows it, guard bounces it"
+mismatches (plain Operator and GlobalReader vs. `/settings` — pending a user decision).
+
+# Examples
+
+Renaming a SignalR message end to end: change the constant in
+`Constants.SignalRMessages` → `AM_WRITE_SHARED_MANIFESTS=1 dotnet test --filter
+SharedManifestParityTests` → `node scripts/generate-shared-manifest-types.js` → tsc
+now flags every stale web subscription literal.
+
+Adding a field to a Settings section: add it to the section in `sectionFieldMap.ts`
+(tsc validates the name against the manifest), wire the form state into the
+`updatedConfig` construction in `TenantConfigContext`, and extend the expected-fields
+list in `sectionFieldMap.test.ts`.

+* **Update**: `mcp/tool-telemetry.md` — the `tool_call` stderr line now carries `errorMessage` (capped at 300 chars; thrown message or the leading `toolError` text, absent on success), so error drilldowns name the failure class instead of guessing from args. Same change: `get_rule_stats` omits the per-rule daily `trend` rows by default (they drove 50% of calls over the response cap at platform scope); `includeTrends=true` opts back in, the response carries a `trendsNote` marker when stripped.
+
+## 2026-08-14 (later)
+
+* **Update**: `rules/analyze-rule-triggers.md` — status SPEC → IMPLEMENTED. Shipped: `evaluateOn` on the analyze-rule schema (grammar-validated server-side and in validate_rule), `AnalyzeRunContext`-driven engine runs (Terminal/Interim/Reanalyze) with the RuleResult lifecycle columns (FirstDetectedAt/LastEvaluatedAt/IsInterim/ResolvedAt/NotifiedAt), interim rule filtering + KO/stat suppression, resolve/finalize update-semantics, the NotifiedAt one-send-per-(session,rule) notification dedupe (preserved across the manual reanalyze rebuild), the ingest-side `InterimTriggerRegistry` (5-min TTL, fail-soft) gating `interim_trigger` / `whiteglove_sealed` enqueues, the three MCP authoring lints, web preliminary/resolved rendering, and ANALYZE-ID-004 as the first interim-enabled rule.
+
+## 2026-08-14
+
+* **Creation**: Added `rules/analyze-rule-triggers.md` — SPEC for opt-in `evaluateOn` interim evaluation of analyze rules: `enrollment_end` default preserves today's behavior, `whiteglove_sealed` + `on_event:<type>` close the WhiteGlove notification gap and the never-terminal stuck-session gap; RuleResults update-semantics (FirstDetectedAt/IsInterim/ResolvedAt/NotifiedAt) replace the permanent dedupe freeze; interim runs suppress KO + stats, notifications fire on first detection; three new validate_rule lints (terminal-precondition trap, unknown trigger type, KO-on-interim).
+
+## 2026-08-13 (late evening)
+
+* **Creation**: Added `drift-guards.md` — the fragility-audit follow-up contracts (P5.x + P7): SignalR message-name catalog in `Constants.SignalRMessages`, exported through the shared manifest and typed into the web's `SignalRContext.on/off` union; the `RowKeyCodec` single encoder for inverted-tick RowKeys (persisted widths pinned, incl. UserActivity's legacy D20); `DeletionRowDump.Table` on tombstone rows with `DeletionTombstoneTables.Resolve` replacing the duplicated `Contains('_')` heuristic (legacy fallback retained one retention cycle); the shrink-only `OkAsyncBaselineGuardTests` per-file baseline (44 sites frozen); the Settings per-section PATCH (section field map + diff-based `config/{tenantId}/fields` writes on the TenantAdmin caller tier); and the web's `scopedApi` endpoint-pair builders, single admin-scope hook, `navVisibility` matrix and guard-consistency ratchet.
+
+* **Update**: `versioning.md` — the web portal joins the version contract commit-only: `public/version.json` generated at build time from `GITHUB_SHA`, served with `Cache-Control: no-store`, polled by `deploy-web.yml` until the deployed commit matches before `versions/web.json` is published.
+
+## 2026-08-13 (evening)
+
+* **Creation**: Added `backend/lifecycle-manifests-and-session-scope.md` — the fragility-audit P5/P6 completeness nets: (1) `TableLifecycleBucketTests` classifies every `TableNames` constant into offboarding-wipe / per-session-cascade / kept-by-design (fixed en route: UsageMetrics wiped via the new RowKey-anchored SafeWipe Variant D — the exact-PK wipe matched 0 rows; PlatformStats tenant partition + ScriptNameCache added to the tenant-PK bucket); (2) `SessionIndexFieldManifest` as the declared SessionsIndex column set with bidirectional builder/reader test pinning, Replace-mode full rebuilds, and a fail-soft merge-key guard; (3) `ResolveSessionScopeAsync` as the single session-scope fallback (16 former copies), backed by the new `SessionTenantLookup` point-read table (scan fallback + self-heal, cascade step before the tombstone), plus the `RecomputeTriggerGate` 403 for reanalyze/rescan by read-only roles; (4) server-side dashboard free-text search (`q=`) with page-backfill loop and fingerprint binding, replacing the client's full-history loadAll sweep.
+
+* **Creation**: Added `backend/app-version-regression-radar.md` — app-version duration regression radar: per (tenant, app) the newest version's median measured install duration (nearest-rank; population Succeeded + non-skip + `HasMeasuredDuration` + no AppId collision + non-empty AppVersion) is compared against the previous version (first-seen ordering, never string sort); fires at median lift ≥2× AND ≥300s absolute with ≥10 measured installs on both sides. Episodes live as `appversionregression|{app}|{version}` tracker rows (one bell `app_version_duration_regression` + one `AppVersionDurationRegression` ops event per episode, refresh keeps `FirstNotifiedAt`, re-arm on drain/median-recovery/30d retention). Surfaces: `versionRegressions[]` + per-version `measuredInstalls`/`medianDurationSeconds`/`p95DurationSeconds` in the apps analytics responses, amber banner + duration-by-version chart on the apps detail page. Kill switch `AppVersionRegressionRadarDisabled`.
+
+## 2026-08-13
+
+* **Update**: `backend/session-annotations.md` — the `/annotations` portal overview page now carries the standard tenant switcher (GA/Reader: "All tenants" aggregate + per-tenant drill-down via `GET global/session-annotations`; delegated: managed subset), with a tenant column and tenant-qualified session deep links. The global list endpoint now derives `excludeGlobalAdminLane` from `HasGlobalScope`, so delegated-rescue callers on their managed `?tenantId=` path never receive the platform-internal `globaladmin` lane (endpoint-test-pinned).
+
+## 2026-08-12
+
+* **Update**: `agent/autopilot-ztd-diagnostics.md` — Windows 365 Cloud PC exception documented: on Cloud PCs `ProfileAvailable=0` is expected (provisioned by the Windows 365 service, not Autopilot), so `autopilot_profile_missing` is emitted as Info with a Cloud-PC-specific message and an `isCloudPc` payload marker (`ResolveAutopilotProfileMissingPresentation`); the portal's Autopilot Profile card renders a neutral note instead of the amber warning for Cloud PC sessions (`session.isCloudPc` or the event marker).
+
+## 2026-08-11 (later)
+
+* **Creation**: Added `backend/session-annotations.md` — session annotations: the new `SessionAnnotations` table (PK=tenantId, RK=`{sessionId}_{lane}`, lanes operator/tenantadmin/globaladmin) storing structured verdicts (`root_cause_confirmed | analysis_wrong | different_problem | inconclusive`) + notes with server-stamped authorship and a fired-rule-id snapshot for join-free rule-quality evaluation. Per-lane write matrix re-gated in-function with own-tenant binding (a GA writes only the platform-internal `globaladmin` lane cross-tenant; tenant callers never see that lane). Surfaces: portal `SessionAnnotationsCard` (session detail, after Analysis), MCP `list_session_annotations` (ga) + `annotate_session` (strictGa, always the GA lane) + `annotations` key in `get_session_summary`. Lifecycle: per-session cascade steps 17–19, offboarding wipe, critical-backup member.
+
+## 2026-08-11
+
+* **Update**: `rules/gather-rule-guardrails.md` — hard-block mirroring closed across all pre-flight layers: `rules/guardrails.json` now also mirrors `blockedCommandPatterns` + `maxCommandLength` and carries `C:\Windows\System32\config` in `blockedFilePrefixes`; portal (`guardValidation.ts`) and MCP (`rule-validation.ts`) apply them in agent order (before the unrestricted-mode early-return), so a command the agent hard-blocks no longer shows "Allowed" in unrestricted tenants. `GuardrailsParityTests` pins the JSON mirror to the C# constants. MCP `validate_rule` additionally validates `json`/`xml` targets with file semantics (the schema's `collectorType` enum was missing both) and rejects `activePhases`+`activeFromPhase` set together (backend 400 parity). Author stamping extended to PUT-upserts: tenant and global gather-rule updates stamp the caller's JWT display name before the service call, so an upsert of a non-existing ruleId can no longer store a payload-supplied author (true updates still preserve the original author).
+
+## 2026-08-10
+
+* **Update**: `rules/gather-rule-guardrails.md` — WMI matcher generalized from literal prefix matching to shape parsing: `SELECT <* | property-list> FROM <class>` is allowed when the class is derived from the existing `SELECT * FROM <class>` entries (a projection is a strict subset; motivated by `SELECT BatteryStatus FROM Win32_Battery` + `on_change` battery polling that `SELECT *` defeats via fluctuating charge %). Same algorithm mirrored agent/portal/MCP; guardrails.json unchanged. Portal now also gates enabling on the client-side validation (invalid-target custom rules create disabled, cannot be toggled on, force-disable on invalid edit, "Blocked on devices" badge) — UX only, the agent guard stays the boundary. Gather-rule Author is now stamped from the creator's JWT (display name → UPN) at create and immutable on update.
 
 * **New**: `agent/continue-anyway-observation.md` — Continue-Anyway observation mode (`EnableEspContinueAnywayObservation`, ConfigVersion 37, operator-set): Device-phase ESP terminal failures on Continue-Anyway profiles are defanged into a 60-min observation window (Classic/Unknown, non-pre-prov only); real-user desktop + Hello gate complete the session as Succeeded + `EspSoftFailure`/`CompletionSource` (amber "with issues" badge + detail banner), category recovery resolves clean, expiry un-defangs to the original `esp_terminal_failure`. Registered in the Agent index section. Related backend fix (no doc): the auto-analyze enqueue now carries a 30 s `visibilityTimeout` so rule evaluation no longer races the agent's terminal flush (ANALYZE-ESP-004's `{{appName}}` placeholder).

+
+# Status
+
+**IMPLEMENTED 2026-08-14** (same day the spec was approved). The open product decisions below were confirmed as "no" for v1. Key implementation anchors: `AnalyzeRuleTriggers` (Shared — grammar + matching helpers, shared by engine, ingest registry and CRUD validation), `AnalyzeRunContext` / `AnalysisOutcome.ResolvedResults` (RuleEngine), `InterimTriggerRegistry` (5-min-TTL per-tenant cache for the ingest hot path, fail-soft), `AnalyzeOnEnrollmentEndHandler` interim branch, `EvaluateOnJson` + five RuleResult lifecycle columns in `TableStorageService.Rules`. ANALYZE-ID-004 ships as the first interim-enabled rule (`on_event:hybrid_login_pending`, repetition-gated at threshold 75).
+
+# Problem
+
+Analyze rules run at exactly three points today, all of them terminal or near-terminal:
+
+1. `enrollment_complete` / `enrollment_failed` observed at ingest (`EventIngestProcessor.cs`, classification → analyze envelope).
+2. The maintenance sweep terminalizing a silent session (Failed / Incomplete + synthetic `session_timeout`, `MaintenanceService.cs`).
+3. The vulnerability-correlation rerun (`vulnerability_correlated` reason — incremental, no stats).
+
+Two incident classes fall through this model:
+
+- **WhiteGlove gap (sits-d, 2026-08-11):** `whiteglove_complete` seals a session to Pending but enqueues no analyze run. A rule that should alert at the end of pre-provisioning (technician still at the bench) never fires, and when Part 2 eventually terminalizes days later, the permanent per-(session, rule) dedupe means a finding that sneaked in earlier (e.g. via the vuln-rerun backdoor) is frozen and never notifies.
+- **Never-terminal stuck sessions (esa-logistics, 2026-08-13/14):** a session looping in Account Setup (user signs in daily, hybrid affinity never establishes) resets the 5h inactivity clock on every logon. It is never terminalized, therefore never analyzed — the exact sessions where a diagnosis would help most (ANALYZE-ID-004, ANALYZE-APP-015) produce no finding while the customer watches the device loop.
+
+Both gaps share one root cause: *evaluation time is hard-wired to session end*. Gather rules already solved the analogous problem on-device with declarative triggers (`startup` / `phase_change` / `phase_exit` / `interval` / `on_event`); analyze rules need the server-side equivalent.
+
+# Design Overview
+
+Add an optional `evaluateOn` array to the analyze-rule schema. Absent field ⇒ `["enrollment_end"]` ⇒ **today's behavior, bit-for-bit, for every existing rule**.
+
+```
+"evaluateOn": ["enrollment_end", "on_event:hybrid_login_pending"]
+```
+
+Trigger grammar (v1):
+
+| Trigger | Fires when | Notes |
+|---|---|---|
+| `enrollment_end` | terminal analyze run (complete / failed / sweep-terminalized) | default; also the **finalization pass** for interim results (below) |
+| `whiteglove_sealed` | ingest classifies the first genuine `whiteglove_complete` (session → Pending, `isPreProvisioned`) | duplicate seals do not re-trigger |
+| `on_event:<eventType>` | an ingest batch contains ≥1 event of `<eventType>` | `<eventType>` validated against the event-types catalog; phase boundaries are covered by `on_event:phase_transition` / `on_event:esp_phase_changed` — no separate phase grammar needed, since every run evaluates the full stream anyway |
+
+Explicitly **not** in v1: interval/timer triggers (no cheap host for them; the sweep remains the only clock), and `on_event` filters on data fields (the rule's own conditions do that — the trigger only decides *when* to look).
+
+# Pipeline Changes
+
+## Ingest (producer side)
+
+- `EventIngestProcessor` already classifies each stored batch. After classification, intersect the batch's event types with the tenant's **trigger registry** (the set of `on_event` types across the tenant's active rules — derivable from `AnalyzeRuleService`'s merged rule load, cached alongside it). Non-empty intersection ⇒ enqueue one envelope `Reason=interim_trigger`, carrying the matched trigger event types. Reuse the existing 30s visibility delay (terminal-flush ordering argument in `AzureQueueAnalyzeOnEnrollmentEndProducer` applies to interim batches too).
+- The `whiteglove_complete` seal path (`EventIngestProcessor.Classification.cs`) enqueues `Reason=whiteglove_sealed` — only on the first seal, only for `isPreProvisioned`.
+- Terminal enqueue (`CompletionEvent` / `FailureEvent`) is unchanged.
+
+## Handler / engine (consumer side)
+
+`AnalyzeOnEnrollmentEndHandler` branches by reason today (primary vs. `vulnerability_correlated`); interim reasons become a third branch. The engine call gets a run context instead of the bare `reanalyze` flag:
+
+| Aspect | Terminal run (`enrollment_end`) | Interim run (`whiteglove_sealed`, `interim_trigger`) |
+|---|---|---|
+| Rule set | ALL active rules (interim-triggered ones get their finalization pass here) | only rules whose `evaluateOn` matches the reason / one of the batch's trigger types |
+| KO (`MarkSessionAsFailed`) | applies (unchanged) | **suppressed** — a Pending/InProgress session must never be flipped Failed by an interim pass (`TryMarkSessionFailedFromRuleAsync` is skipped; the terminal run re-fires the rule and applies KO then) |
+| Platform stat `IssuesDetected` | counted | skipped (like vuln rerun) |
+| Per-rule fire stats | counted | skipped (like vuln rerun) — keeps the terminal-only stats convention and the Rule Regression Radar baselines clean |
+| Channel notifications | new findings notify (unchanged) | new findings notify — **this is the point** of both gaps |
+| SignalR results-available | yes | yes (live update of an open session page) |
+
+## Result lifecycle: update semantics replace the dedupe freeze
+
+Today the engine skips any rule that already has a stored `RuleResult` row for the session (`RuleEngine.AnalyzeSessionAsync`, existing-results lookup) — findings are frozen at first write, which is precisely the WG-gap failure mode ("dedupe permanent").
+
+New model — `RuleResult` gains four fields (`FirstDetectedAt`, `LastEvaluatedAt`, `IsInterim`, `ResolvedAt`, plus `NotifiedAt` for the notification marker):
+
+- **Interim run:** rules in scope are (re-)evaluated even when a row exists. Fired ⇒ upsert (evidence/confidence refreshed, `FirstDetectedAt` preserved, `IsInterim=true`). Not fired + existing interim row ⇒ `ResolvedAt` set (kept for audit; excluded from issue counts and default UI).
+- **Terminal run:** every rule that has an interim row is re-evaluated regardless of dedupe (finalization). Fired ⇒ row finalized (`IsInterim=false`, evidence refreshed — fixes the stale-template-field freeze, e.g. the ESP-004 `{{appName}}` case). Not fired (typically a `not_exists` precondition on `enrollment_complete` now failing because the session healed) ⇒ `ResolvedAt` set. Rules without interim rows keep today's skip-if-exists dedupe.
+- **Notification dedupe** moves off "row exists" onto `NotifiedAt` on the row: notify once per (session, rule) at first fire — interim or terminal, whichever comes first; refreshes and finalization do not re-notify. The manual `reanalyze=true` path must **preserve** `NotifiedAt` across its rebuild (today it deletes rows; delete-and-recreate would silently re-arm notifications) and keeps its designed never-notify behavior.
+- Legacy rows (null new fields) read as final/terminal — no migration.
+
+# Authoring Guardrails (validate_rule lints)
+
+Interim evaluation changes what a rule's conditions mean mid-flight. Three new lints in the MCP `validate_rule` pre-flight (and the baked authoring guide):
+
+1. **Terminal-precondition trap (warning):** `evaluateOn` contains an interim trigger AND a precondition is `not_exists` on `enrollment_complete` / `enrollment_failed` / `session_timeout`. Mid-run these pass trivially — the rule needs conditions that are *monotonic* (once true on the growing event stream, stays true) or repetition-gated. Worked example: ANALYZE-APP-015 must NOT get an interim trigger as-is — even successful sessions transiently show its "completion signal deferred" + `pending>=1` pattern (the terminal precondition is its only gate). ANALYZE-ID-004 is interim-safe by construction (threshold 65 requires repeated `hybrid_login_pending`).
+2. **Unknown trigger event type (error):** `on_event:<type>` not in the event-types catalog.
+3. **KO-on-interim (warning):** `markSessionAsFailedDefault: true` on a rule whose only triggers are interim — the KO would never apply until terminal; say so.
+
+# Cost & Safety
+
+- Interim runs are bounded by trigger frequency, and the chosen v1 triggers are rare by construction (`hybrid_login_pending` ≤1 per boot, `whiteglove_sealed` once per session). High-frequency telemetry event types (performance_snapshot, agent_metrics_snapshot, download_progress, network churn, log_entry, agent_trace, stall_probe_check) are **hard-blocked** as `on_event` triggers, not merely advised against: the CRUD write is rejected (`AnalyzeRuleTriggers.BlockedOnEventTypes`, code-only enforcement), the runtime matcher drops them from any row that slipped in (defense in depth — the trigger registry and the engine both go through `OnEventTypes`), and the MCP lint reports them as an error. The JSON mirror lives in `rules/guardrails.json` (`blockedInterimTriggerEventTypes`) with a parity test pinning it to the C# set — the same pattern the gather hard blocks use. If a legitimate rare-but-bursty type ever hurts, a per-(session, reason) throttle marker is the v2 lever.
+- Each run loads the full event stream once (existing engine behavior, no change); rule filtering makes interim passes strictly cheaper than terminal ones.
+- Queue semantics (retry via visibility timeout, poison after MaxDequeueCount, idempotent partial-success re-runs) are inherited unchanged; upserts keep idempotency.
+
+# Surfaces
+
+- **Web session page:** interim findings render live (existing SignalR results-available notification) with a "preliminary" badge on `IsInterim`; `ResolvedAt` rows hidden by default behind a toggle.
+- **MCP:** `get_session(includeAnalysis)` / `get_session_summary` expose `isInterim` / `resolvedAt`; `list_session_annotations`' fired-rule snapshot semantics unchanged (labels bind to whatever was fired at annotation time).
+- **Success-rate / platform stats:** terminal-only convention untouched (interim runs record no stats).
+
+# Application to the Motivating Cases
+
+- WG battery rule (sits-d): `evaluateOn: ["enrollment_end", "whiteglove_sealed"]` — technician gets the channel alert at the bench; Part-2 terminal pass finalizes or resolves the finding.
+- Hybrid-affinity stuck (esa): ANALYZE-ID-004 gets `evaluateOn: ["enrollment_end", "on_event:hybrid_login_pending"]` — the second overdue-login event (threshold 65) produces a live finding on the still-InProgress session. ANALYZE-APP-015 stays `enrollment_end`-only until its conditions are hardened (lint 1).
+
+# Product Decisions (settled 2026-08-14)
+
+1. Notify-on-resolve (a "finding healed" message)? **No** (v1) — resolution is visible in UI/MCP.
+2. Re-notify on severity/confidence escalation of an existing finding? **No** (v1) — one notification per finding.
+3. `whiteglove_sealed` runs allowing KO rules to flip Pending → Failed? **No** — the Pending state is the WhiteGlove contract; suppression is unconditional for interim.

+This is the security boundary. The portal's `ValidationIndicator` is a convenience — the API stays reachable directly and the backend stays validation-free — but since 2026-08 the portal additionally **gates enabling** on the same client-side validation: a custom rule whose target fails validation cannot be toggled on, is created `enabled=false`, and an edit that makes the target invalid force-disables the rule (`targetBlocked` in `app/gather-rules/types.ts`). An enabled rule with an invalid target shows a "Blocked on devices" badge. All of this is UX, not security — the agent guard remains the enforcement point.
