* feat(backend,web): Telegram als Channel-Provider + ein einziger Dispatch-Pfad

Notifications hatten zwei Sendewege: WebhookNotificationService.SendToChannelsAsync fuer
tenant-konfigurierte Channels, und TelegramNotificationService direkt aus dem Ops-Alert-Pfad.
Ein neuer Provider haette beide anfassen muessen.

Neu: NotificationChannelDispatcher ist DIE Channel-Sende-API und routet pro Provider —
WebhookProviderType.Telegram zum Bot, alles andere als gerenderten Webhook-POST.
SendToChannelsAsync wurde aus WebhookNotificationService entfernt statt dupliziert, damit es
keinen zweiten Pfad gibt; alle sieben Call-Sites ziehen um (EventIngestProcessor, RegisterSession,
ReportDistress, SlaBreachEvaluation, AnalyzeOnEnrollmentEnd, TestWebhookNotification).
SendOpsAlertAsync/SendNotificationAsync sind virtual (Test-Seam), TelegramNotificationService
bekommt SendAlertWithResultAsync fuer die Test-Endpoints und RenderAlertText als testbaren Kern.

Telegram (=40) ist der Sonderfall: kein Webhook. Der Channel-Url traegt die CHAT-ID, der Bot-Token
gehoert der Plattform (PreviewConfig). Ein Tenant-Admin wuerde durch UNSEREN Bot senden — deshalb
ist das Gate eine Server-Regel, keine versteckte Dropdown-Option:
ValidateTelegramChannelGate sitzt in TenantConfigValidation.ValidateModel und deckt damit BEIDE
Schreibpfade ab (Full-Model-PUT und den MCP-Field-Patch ueber TenantConfigPatchService) — in der
Update-Function allein waere der Patch-Pfad daran vorbeigelaufen. Ein unveraenderter, GA-angelegter
Channel passiert das Gate, damit ein Tenant-Admin unrelated Config weiter speichern kann.
Telegram-Ziele ueberspringen SsrfGuard.ValidateWebhookUrlFormat (eine Chat-ID ist keine URL und
wuerde immer failen) und werden stattdessen als numerische Id oder @username geprueft.

Mitgeliefert, weil der Dispatcher und die Ops-Seite sie brauchen: NotificationChannel.RedactList /
RestoreRedactedList als geteilte Helfer hochgezogen (TenantConfiguration delegiert jetzt dorthin,
statt eine zweite Kopie zu pflegen), AdminConfiguration.OpsNotificationChannelsJson +
GetOpsNotificationChannels() mit Legacy-Slot-Synthese, OpsAlertRule.NotifyChannelIds/IncludePayload,
NotificationAlert.DataJson (nur GenericJsonRenderer serialisiert es, additiv in schemaVersion 1.0).

Web: der Channel-Editor liegt jetzt in components/notifications/ChannelEditor.tsx und wird von
Tenant- und Admin-Seite geteilt (showEventToggles trennt die Faelle). Telegram erscheint im
Provider-Dropdown nur fuer Global Admins (Prop aus useAuth().user?.isGlobalAdmin, Hausmuster aus
SectionAutopilotValidation); ein bereits konfigurierter Telegram-Channel bleibt fuer alle sichtbar,
damit ein Speichern ihn nicht still verwirft.

Tests: TelegramChannelProviderTests (27) — Dispatcher-Routing inkl. "Telegram erreicht NIE den
SSRF-Pfad", Chat-ID-Validierung, GA-Gate auf beiden Schreibpfaden. Mutationsgeprueft: Gate
invertiert => 5 rot, zurueck => 27 gruen. OpsNotificationChannelsTests + OpsAlertPayloadTests
decken die mitgelieferten Modell-Additionen ab. TestNotifications ist der gemeinsame inerte Stub,
der die 17 bestehenden OpsAlertDispatchService-Konstruktionen ersetzt.

* feat(backend,web): Ops-Alerts routen auf benannte Channels statt auf drei feste Slots

OpsAlertRule hatte kein Ziel. Jede matchende Regel ging an alle drei fest verdrahteten Slots in
AdminConfiguration (Telegram-ChatId / Teams-URL / Slack-URL), und nur die ERSTE matchende Regel
wurde ueberhaupt ausgewertet (FirstOrDefault). Ein Conversion-Signal an ein Sales-Team zu binden
hiess also: das Sales-Team bekommt auch jede Security-Regel.

Jetzt: AdminConfiguration.OpsNotificationChannelsJson haelt eine benannte Channel-Liste (dasselbe
NotificationChannel-Modell wie tenant-seitig, nur anderer Scope), und OpsAlertRule.NotifyChannelIds
bindet Regeln daran. Dispatch wertet ALLE matchenden Regeln aus (Where statt FirstOrDefault) und
vereinigt ihre Ziele.

Rueckwaertskompatibel ohne Migrationsjob:
- Leere Channel-Liste => GetOpsNotificationChannels() synthetisiert je konfiguriertem Legacy-Slot
  einen Channel mit stabiler Id (legacy-telegram heisst "Autopilot Monitor IT Engineer") und
  uebernimmt die Legacy-Enabled-Flags — ein bewusst abgeschalteter Provider bleibt abgeschaltet.
- GetAdminConfigurationFunction projiziert DIESELBE Synthese in das Read-Model, damit der Editor
  zeigt, was heute tatsaechlich Alerts empfaengt, und der erste Save exakt das materialisiert.
  Die Alternative waere eine zweite Kopie der Synthese-Regeln im Web gewesen, die vom Dispatcher
  wegdriftet.
- Leere NotifyChannelIds = alle aktivierten Channels. Das ist, was jede heute existierende Regel
  traegt, also verhaelt sich am Deploy-Tag nichts anders.
- Ids, die nicht mehr aufloesen, werden verworfen statt auf Broadcast zurueckzufallen: eine Regel,
  deren einziger Channel geloescht wurde, muss NICHTS erreichen, nicht alles.

Die Legacy-Felder bleiben als Migrationsquelle stehen und werden von der Alerts-Section nicht mehr
geschrieben — aufraeumen erst, wenn produktiv Channels stehen.

Sicherheit: OpsNotificationChannelsJson ist secret-tragend und steht in der Deny-List von
RedactedCopyForReader() (ConfigRedactionTests bewacht Drift). Der Admin-PUT hat bisher keinen
Redacted-Restore — er bekommt jetzt einen fuer die Channel-Liste, damit ein zurueckgespieltes
Reader-View nicht "***REDACTED***" als Chat-ID persistiert, plus die strukturelle Validierung, die
auch die Tenant-Liste passiert.

Neuer Endpoint POST /api/global/config/test-ops-channel (GlobalAdminOnly, im Policy-Catalog
registriert). Kein neues Response-DTO: TestWebhookNotificationResponse hat identische Semantik und
wird geteilt — nur der Doc-Kommentar nennt jetzt beide Routen.

Web: die "Alert Providers"-Karte weicht der Channel-Liste (geteilter ChannelEditor, im Admin-Kontext
mit Telegram und ohne die tenant-spezifischen Event-Toggles). Jede Regel bekommt einen
Channel-Picker; leere Auswahl rendert als "all channels", nicht als Warnung — hier ist das der
gueltige Default. Die Bindungslogik liegt testbar in opsChannelRouting.ts und spiegelt
ResolveTargets: der erste explizite Pick startet vom LEEREN Set, sonst liesse sich eine
Broadcast-Regel nie verengen. handleSaveOpsAlertConfig nimmt jetzt ein Objekt statt elf
positionaler Argumente — bei einem Dutzend Feldern schreibt ein vertauschtes Paar sonst still eine
Webhook-URL in den falschen Provider-Slot.

* feat(backend): TenantTrialStarted + Event-Payload optional pro Regel

Der Trial-Start war stumm. POST config/{tenantId}/trial schrieb nur einen Audit-Entry, und der
GA-Pfad (PATCH plan) feuerte nur beim Downgrade — also war genau der Conversion-Moment, den
Sales/Support interessiert, das einzige Plan-Ereignis ohne Ops-Event.

RecordTenantTrialStartedAsync (Tenant/Info) feuert jetzt aus BEIDEN Schreibpfaden, unterschieden
per selfService-Flag, und jeweils NACH dem persistierten Save (SaveConfigurationAsync ist
fail-loud), damit kein Alert eine Trial ankuendigt, die nicht gespeichert wurde. Der GA-Pfad
haengt an der aufgezeichneten Aenderung, nicht am Request: ein reiner planTier-Edit bleibt still,
ein idempotenter Save mit demselben Datum ebenfalls, und das Beenden einer Trial (explizit null)
ist ein Downgrade und bleibt bei TenantPlanDowngraded.

Payload-Zustellung: WriteAsync reicht die serialisierten Details an DispatchAsync durch — aber ein
Channel bekommt sie nur, wenn eine Regel OpsAlertRule.IncludePayload setzt. Default AUS, bewusst:
ein Ops-Alert ist ein "da ist was, schau nach"-Signal, die meisten Payloads sind im Chat Rauschen,
und manche tragen Felder, die die Baseline nie traegt (Tenant-Domain, Contact-Adresse). Das
Informationsniveau aller bestehenden Regeln bleibt damit unveraendert.

ResolveTargets liefert deshalb zwei Gruppen. Ein Channel, den sowohl eine Payload-Regel als auch
eine schlichte Regel adressiert, landet nur in der Payload-Gruppe: eine Nachricht pro Channel, und
ein unbeteiligtes Geschwister-Match kann ein bewusstes Opt-in nicht aushebeln.

Fuer den angereicherten Alert flacht BuildAlert die Top-Level-Skalare in Facts ab (max 12, Werte
<= 256 Zeichen, Nulls und Verschachteltes raus), damit Card-Formate und der Telegram-Klartext
dieselbe Information tragen wie der GenericJson-Consumer unter "data". EventType wird immer
gesetzt — derselbe Wert steckt schon im "Event"-Fact, also keine zusaetzliche Information, nur ein
stabiler Schluessel zum Verzweigen.

Tests: TenantTrialStartedEventTests (8) — aufgezeichnete Event-Form inkl. Payload-Feldern, und die
Emissionsbedingung des GA-Pfads gegen ApplyPlanChanges gepinnt (greift bei Grant und Verlaengerung,
schweigt bei Trial-Ende, planTier-only und idempotentem Save). Die HTTP-Entry-Points bleiben
ungetestet — Suite-Konvention ist, die reinen Kerne zu testen.

Docs: OKF-Concept backend/ops-notification-channels.md. Registrierung in docs/index.md +
docs/log.md fehlt bewusst — beide Dateien tragen noch fremdes uncommittetes WIP (ops-events
Query-Surface), und ein Teil-Commit darin haette es mitgenommen.

* feat(backend,mcp): ops-events server-side field filters + generated MCP tool vocabularies

The ops-events read could only narrow by category and date window, so answering
"did any AgentEmergencyBreak fire yesterday?" meant pulling a whole category and
filtering it client-side — and for the MCP tool that client is a language model,
so the question cost a category-sized response in model context.

Ops-events filter surface (mirrors the audit-log filter pattern one-for-one):
- OpsEventQueryFilters (Shared) + OpsEventFilterRequest (query -> filters +
  pagination extras) + TableOpsEventRepository.AppendFieldFilters (filters ->
  OData clauses). BOTH filter builders call the appender — the single-category /
  unpaged one and the per-partition fan-out builder that adds the RowKey bound —
  so "no category named" cannot silently return unfiltered rows.
- minSeverity expands to an OR-set, not a range: Table Storage compares strings
  lexicographically and the severity names sort Critical < Error < Info <
  Warning, so `Severity ge 'Warning'` would drop exactly the alert-worthy half.
  The ladder now lives in OpsEventSeverity.Rank, shared with
  OpsAlertDispatchService, so "Warning and above" in a read means what it meant
  when the alert rules fired.
- severity is normalised onto the canonical vocabulary and an unknown value is a
  400: `eq` is case-sensitive, so "?severity=warning" would otherwise return an
  empty page that reads exactly like "no such events happened". eventType stays
  verbatim — stored rows outlive the vocabulary, so a retired type must remain
  searchable in the historical window.
- Every filter value is folded into the continuation fingerprint and echoed on
  nextLink; extras are appended AFTER the pre-existing category/tenantId
  discriminators and skipped when empty, so tokens minted before the filters
  existed still fingerprint identically. The tenantId drill deliberately stays
  in memory (OrdinalIgnoreCase; an OData eq would lose rows on casing).
- MCP get_ops_events gains eventType / severity / minSeverity plus a `days`
  shorthand resolved client-side to a concrete dateFrom (a backend-side "last N
  days" would re-resolve "now" on every page and blow the token fingerprint);
  an explicit bound always wins over the shorthand.

Fixed alongside: the paged cross-category fan-out skipped Platform (Azure
Monitor alerts) because its category list had drifted from OpsEventCategory —
written from day one, invisible to every paged reader, still visible on the
unpaged full-table path. The list is now OpsEventCategory.All plus a reflection
coverage test.

That drift had a structural cause, so the same round closes it for the MCP as a
whole: wire TYPES reached the MCP from day one, but vocabularies did not — types
are erased at runtime and z.enum() needs values, so every tool schema hand-typed
its own copy with nothing to compare against. The copies had drifted:
search_sessions offered 5 of 8 session statuses (no AwaitingUser, no Incomplete
— both real stored statuses), both event readers offered 4 of 6 severities (no
Debug, no Trace), get_ops_events named 6 of 7 ops categories.

- The codegen now emits src/generated/wire-vocabularies.generated.ts (VALUES:
  session statuses, event severities, ops categories/severities/types,
  annotation lanes/verdicts) from the manifest sections listed in
  MCP_VOCABULARIES; SharedManifestParityTests exports the two new ops
  vocabularies. Freshness is pinned twice — byte-equality against a fresh
  codegen run in the MCP suite, and the shared-manifests-in-sync CI job.
- Tool schemas derive their z.enum() from it and descriptions interpolate the
  list instead of spelling it.
- vocabulary-drift.guard.test.ts ratchets what is left: every inline z.enum([..])
  must sit on a baseline naming why it has no backend owner (MCP-local knobs,
  plus rule type / connection type / CVE risk, which have no C# constants class
  yet). A new hand-typed list fails, and so does a stale baseline entry.
- OpsEventTypes (Shared) gives the 77 ops event types a canonical home: the
  OpsEventService write sites use the constants (a raw literal now fails
  OpsEventTypeDualRegisterTests, which moved from regex-scraping to reflection),
  the manifest exports them, and get_resource(name="ops_event_types") serves
  categories + severities + types to the model from the generated copy.

Suites: Backend 5427, MCP 629 + tsc, Web tsc + vitest 965, generator idempotent.

Deploy order: backend BEFORE the MCP redeploy — an MCP that sends filters to an
older backend gets silently unfiltered rows back and presents them as filtered.

Oliver Kieselbach 0a0c323f73 fix(backend): CMTrace skew tripwire judges only the current ingest era
Three CmTraceTimeSkewRegression fires on 2026-09-01 (one tenant, sessions
e797117b / c06d639d / d7c8032b, agent 2.0.1445, each exactly -60.0 min,
residual 0.0, 85-88 % grid-conformant) all came from the same stale leg: those
sessions are pre-provisioning, their Part 1 ran on 2026-08-20 under agent
2.0.1409 (before per-line anchoring) and left 23-26 IME samples at -60.00,
while the Part 2 leg that completed that morning is clean at -0.16. The
terminal reconcile scans the whole event partition, so the old leg supplied the
majority of the IME samples and fired against a build the device had
self-updated to minutes earlier. Real skew, 12 days old, already fixed - and
>=821 pending pre-provisioning sessions with agent < 1412 are queued to repeat
it.

Event rows carry no agent version, so the split is drawn on ReceivedAt:
ResolveEraStartUtc walks the batch stamps of BOTH sides back from the newest
one and ends the era at the first gap > EraGapHours (2.0) - above any in-leg
upload gap (self-metrics every few minutes, session_stalled at 60 min idle,
maintenance sweep at 2 h), below every pre-provisioning handover. Median, grid
residual, conformity AND the distinct-batch guard now all run on the same
era-filtered sample set; the batch counters used to come from the full scan.
SessionSkewScan carries ReceivedAt per sample and its 20k cap keeps the NEWEST
samples (chunked trim) - keeping the head would have blinded the detector on
exactly the sessions large enough to reach it. The ops event reports
eraStartUtc plus the excluded per-side counts, so an inherited leg stays
visible without being alarmed on.

Tests: 3 new era facts, mutation-proven (EraGapHours = 100000 turns exactly
those three red). The handover fact also asserts that the old leg judged on its
own still fires, so it is the window that silences it, not a moved threshold.
Backend 5334 green, Agent core 2805 green, solution builds with 0 warnings.

Oliver Kieselbach eaef1601d0 feat(backend,mcp,web): typisierung follow-up — the deliberately-untyped remainder is typed end-to-end, and the raw table entities leave the wire (#137)
Closes the documented read-model follow-up of the typed API contract (51737174). Three categories:

WIRE-IDENTICAL moves/substitutions (parity facts where a literal changed, move-only otherwise): RuleDryRun + trace classes and RuleDryRunVerdict move to Shared/RulesApiModels (DryRunAnalyzeRuleResponse.Result concrete; Evidence/MatchedConditions stay heterogeneous by design); BackfillResult(+Sample)/ReclassificationResult(+Sample)/MaintenanceResult move to Shared/AdminApiModels — the shared MaintenanceJobRunResponse union envelope is split into BackfillJobRunResponse/ReclassifyJobRunResponse (identical key layout, split only for the typed slot); TenantConfigFieldSchema moves as a plain class with the record's constructor signature (Shared has no IsExternalInit — call sites just lowercase their named args); HealthCheck moves (HealthCheckResult stays in Functions, it never hits the wire); GlobalNotificationDto moves (one DTO, both notification endpoints); GetMetricsSummaryAsync builds MetricsSummaryTenantItem instead of the anonymous row ([ProjectedItems] dropped, slot concrete, substitution parity fact incl. the per-item windowDays duplicate; IMetricsRepository signature follows).

UNTYPED ENDPOINTS -> DTO (parity facts mandatory): auth/me success body becomes AuthMeResponse (15 keys in exact wire order; role null-omission fact; blocked arms stay anonymous error shapes; AuthFunctionTests.ToDynamic now exposes wire casing so asserts read camelCase for DTOs and error literals alike). auth/mcp becomes CheckMcpAccessResponse — the four fixed keys are non-nullable strings on McpAccessCheckResult, so the dictionary never emitted null values and WhenWritingNull changes nothing; the four conditional keys are nullable slots in exact insertion order, isGlobalAdmin emitted only as literal true; three facts pin plain/platform+delegated/denied against the old Dictionary literal.

ENTITY-HYGIENE (DELIBERATE wire change, exact-JSON shape pins instead of parity facts): GetGlobalAdminsResponse/AddGlobalAdminResponse serve GlobalAdminRow, GET+POST tenants/{id}/admins serve TenantAdminRow, preview/whitelist serves PreviewWhitelistTenantEntry { tenantId } — partitionKey/rowKey/eTag/timestamp (and the whitelist's garbage approvedAt/approvedBy defaults) are gone from the wire. Every wire instance was synthetically back-mapped from Shared read models (GlobalAdminEntry/TenantMember) anyway; the services now map forward into the rows and the ITableEntity types stay storage-only. Consumer audit (web+MCP) found exactly ONE reader of a table key: AdminConfigContext preview-approval (t.partitionKey -> t.tenantId, same change). Shape pins assert the full JSON and table-key absence.

Guard: TypedResponseGuardTests gains an object-slot reflection ratchet over the reachable wire-type graph (IApiResponse + [WireContract] roots, transitive property walk; [ProjectedItems] slots and dictionary values exempt) with mutation-proven red/green; baseline holds exactly RuleDryRunCondition.Evidence, and stale entries fail the ratchet-down arm.

Codegen: manifest 298->311 exported types, every former unknown slot concrete in both wire-types.generated.ts copies; generator idempotent. MCP adopts: access-guard.ts drops its inline auth/mcp cast for CheckMcpAccessResponse (defensive delegatedTenantIds normalization kept), rules.ts drops the local RuleDryRun view (the dead verdict cast disappears; matchedConditions feeds interpolateRuleTemplate typed), get_tenant_config_schema gets its envelope type. Web adopts: new types/auth.ts shim (TenantRole/HomedApp narrowing over AuthMeResponse), AuthContext.UserInfo derives from the wire type and both duplicated as-cast mapping blocks collapse into one toUserInfo(); health-check page, notification contexts and the TenantAdmin types re-export generated interfaces.

Deliberately untouched: config/all + tenants/{id}/admins stay bare arrays (typed items, envelope would break four array-typed web readers — ime-versions precedent); error bodies stay anonymous; error-body ratchet remains a separate PR; the two documented guard baseline entries stay.

Suites: Backend 5330, Agent 2805, DecisionCore 577, SummaryDialog 44, MCP tsc 0 + 617, Web tsc 0 + vitest 957 + eslint 0; solution builds warning-free.

Deploy note: backend + web + MCP all need deployment; the category-C wire change is only visible in the GA admin UI (preview-approval badges) between backend and web deploy.

Oliver Kieselbach d055eed074 Typed API contract: every success response is a wire DTO, generated end-to-end into TypeScript (#136)
* feat(backend): typed API response infrastructure — IApiResponse marker, wire-settings single source, widened anonymous-body ratchet (batch 0 of typed-api-contract)

IApiResponse (Shared, with SuccessMessageResponse/SuccessOnlyResponse and the
ProjectedItems/WireContract attributes for the upcoming manifest export) plus generic
OkAsync/CreatedAsync/JsonAsync<T> overloads constrained on it, so anonymous success
bodies stop compiling once the legacy object overloads go; ApiJsonOptions is now the
single source of the production wire settings (camelCase, WhenWritingNull, string
enums) used by Program.cs AND the three endpoint-test harnesses (two serialized
PascalCase-with-nulls, one JsonSerializerDefaults.Web — all could pass while the
deployed wire differed); TypedResponseGuardTests replaces OkAsyncBaselineGuardTests
with the same ratchet mechanics over two frozen baselines (44 anonymous helper sites
unchanged, plus 134 anonymous success WriteAsJsonAsync sites across 76 files —
error-shaped bodies stay anonymous by design) and a flatness/location reflection
guard (IApiResponse implementers derive from object and live in Shared, protecting
JSON key order); ApiResponseWireParityTests carries the ordinal old-vs-new
serialization proof each converted site must add

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(backend): Sessions/Annotations/Reports/Raw/Progress success responses are typed wire DTOs (batch 1 of typed-api-contract)

34 anonymous success bodies across 24 functions replaced with flat IApiResponse DTOs
in Shared (SessionApiModels/ReportApiModels + new Annotation/Raw/ProgressApiModels) —
minimal in-place transformation, call structure/status codes untouched, declaration
order == wire order, nullable exactly where a site can emit null (WhenWritingNull);
fields= projections stay IReadOnlyList<object> marked [ProjectedItems(SessionSummary/
EnrollmentEvent)], raw table rows stay PascalCase-verbatim dictionaries (no
DictionaryKeyPolicy — pinned by test), AnnotationWire and the distress-report
aggregations now build named item types instead of anonymous ones, and shared shapes
collapse to one DTO (SessionListResponse x4, SessionAnnotationListResponse x2,
SessionReportListResponse/GetSessionEventsResponse paged+unpaged via absent-null
nextLink); 54 new wire-parity facts serialize each OLD anonymous literal (independent
fixture copied from the pre-migration site) against the new DTO ordinally, with a
null case per vanishing key; ratchet baselines shrink 44->14 helper sites and
134->122 write sites; the three distress-report test files read the now-typed
aggregation items directly instead of via reflection-ToDynamic

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(backend): every anonymous API success body is a typed wire DTO — ratchet baselines empty, legacy object overloads deleted (batches 2-5 of typed-api-contract)

the remaining 141 anonymous success sites (Admin 36, Rules 24, Config 15, Graph 5,
Metrics 16, Vulnerability 17, Infrastructure/Global/Notifications/Bootstrap/
Diagnostics 20 incl. the 429 quota body in McpQuotaEnforcementMiddleware, plus the
14 helper-call sites) now return flat IApiResponse DTOs from Shared (new Admin/
Rules/Config/Graph/Metrics/Vulnerability/Infrastructure/Notifications/Diagnostics
ApiModels; GeographicApiModels extended) — same minimal in-place transformation as
batch 1: declaration order == wire order, nullable exactly where a site can emit
null, dual success/failure sites keep their status-code logic and reuse
SuccessMessageResponse, MCP-critical key names (records/summaries/inventory)
pinned; wire item shapes that were function-local (CustomsArchive Run/EntrySummary,
CpeMappingDto, UnmatchedSoftwareAgg, AutoResolve items, LogPatternTestResult,
CveExposureSummary/SeverityBreakdown/TopCve — records rewritten as flat classes,
netstandard2.0 has no IsExternalInit) moved to Shared so the manifest export sees
them; payload types that must stay in the Functions assembly (RuleDryRun,
PreviewWhitelistEntity, GlobalAdminEntity, HealthCheck, GlobalNotificationDto,
Backfill/Reclassification/MaintenanceResult, TenantAdminEntity,
TenantConfigFieldSchema) ride as object slots — wire-identical via runtime-type
serialization, proven by the parity facts; 126 new wire-parity facts total
(Admin 26, Rules 12, Config 17, Graph 7, Metrics 16, Vulnerability 19,
Infrastructure 21 + Dictionary-key-verbatim and null-value pins); both
TypedResponseGuard baselines are now EMPTY regression guards and the untyped
OkAsync/CreatedAsync(object) overloads are gone, so a new anonymous success body
no longer compiles through the helper and fails the guard through raw
WriteAsJsonAsync; deliberately untouched: error bodies (one anonymous shape by
design), auth/me (AuthDecisionResult.Body slot shared with error bodies, tests
reflect over it), CheckMcpAccess (conditional dictionary keys), raw-byte streamers

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(contract): C#→TS wire codegen — shared-manifests v2 exports the full response-type graph as generated TypeScript (batch 6 of typed-api-contract)

SharedManifestParityTests now writes schemaVersion 2: the v1 catalog sections stay
byte-compatible (sectionFieldMap/signalrMessages/sharedManifestChecks untouched),
the consumer-less sessionSummary section is gone, and a new types section carries
every wire type — roots are all IApiResponse implementers plus [WireContract]-marked
types (SlaViolatorSession, ImeVersionHistoryEntry), transitively closed by the new
WireTypeManifestBuilder over refs, collections, dictionaries, enums and
[ProjectedItems] item types (208 types). Fields honour [JsonPropertyName]/
[JsonIgnore], get-only members export readonly, a nullable slot exports optional
(WhenWritingNull omits the KEY — explicit null survives only inside collections and
dictionary values, so the nullable flag lives on nested descriptors only), field
order follows STJ's derived-before-base serialization for the one legacy inherited
wire type (LocationSessionRow : SessionSummary), and unmappable shapes (non-string
dictionary keys, foreign BCL classes) fail the build instead of degrading to
unknown. C# <summary> texts travel as JSDoc: Shared builds XML docs now (doc-quality
warnings CS1591/1573/1574/1584/0419 suppressed — crefs to foreign assemblies cannot
resolve from Shared; CS1570 malformed-XML stays an error, which surfaced a raw
0x01 control char and an unescaped ampersand in existing comments).
generate-shared-manifest-types.js emits utils/wire-types.generated.ts (interfaces +
string-union enums, 2.7k lines) next to the lean literal module, npm run
generate:manifests wraps it, the vitest freshness test pins BOTH outputs, and a new
shared-manifests-in-sync CI job (guardrails-in-sync pattern) fails on drift

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(web): hand-written response types re-export the generated wire interfaces (batch 7+8 of typed-api-contract)

types/session.ts, types/enrollment.ts and types/adminConfig.ts are re-exports over
utils/wire-types.generated.ts (Session = SessionSummary alias for the 25+ barrel
importers; adminConfig keeps only the excessiveEventAutoActionMode literal-union
narrowing and the client-side OpsAlertRule view) — the generated types are never
weakened, consumers adapt: durationSeconds is now optional as on the wire (int? —
consumers guard with ?? 0, which also retires the latent NaN-minutes display on
in-progress sessions), status is the SessionStatus union (fixtures on canonical
values; the generic string-sort test keeps its own fixture type), required bools
break hand-built fixtures once → new test/factories.ts makeSession/makeEvent
(Object.assign, not spread — Partial spread re-widens and tests must force
data: undefined); the string|null lifecycle branches were already truthiness-based.
Duplicate local types deleted: geographic-performance now uses the real
LocationSessionRow wire type (incl. DO fields), GlobalSearch the generated
QuickSearchResult, sla/page.tsx the generated SlaViolatorSession (status stays a
number — C# int, rendered via statusLabels); sessionExportUtils aliases
SessionExportEvent = EnrollmentEvent and derives RuleResultCsvData via Pick, CSV
output unchanged; the three structural ReplayInputEvent clones (InstallEvent,
ScriptInputEvent, DownloadEvent) are aliases now. docs: drift-guards.md replaces the
shrink-only-OkAsync section with the typed-wire-DTO contract, index.md/log.md
updated. tsc 0, vitest 957, eslint 0

Oliver Kieselbach 5f3ae2d06b fix(backend): SessionTenantLookup is claimed first-writer-wins at registration — the sessionId→tenantId row that every Global Admin/Reader cross-tenant session resolve trusts was an unconditional last-writer-wins upsert AFTER the session write keyed by the client-supplied sessionId, so any tenant's device (self-service onboarding) that knew a victim session GUID (portal deep links, Teams/Slack notifications, progress-portal URLs) could re-point the mapping at its own tenant and have every no-tenantId GA read and GA write (globaladmin annotation lane, restore fallback) silently served from a forged session; StoreSessionAsync now claims the row create-only BEFORE any Sessions/SessionsIndex write (409 → read owner: same tenant = re-registration, foreign tenant = SessionTenantConflictException → 409 session_owner_mismatch without disclosing the owner + SessionTenantConflict ops event, nothing written, not fail-soft), the legacy self-heal write is Add-only, ResolveSessionScopeAsync(requireGlobalAdmin) corroborates the resolved tenant against its Sessions row (silent, no operator confirmation), and scripts/Migration/Backfill-SessionTenantLookup.ps1 closed the pre-table window (13509 sessions, 8795 rows added, verify dry-run added=0); no tombstone on deletion by design

Oliver Kieselbach 83e15e49de fix(core,backend): every payload-derived string stored into DecisionState is bounded (FactStringBounds, 256) and the reducer-verification replay streams signals — RealmJoinFacts.WithPackageStarted/Completed left PackageId/Version/Scope unbounded and deduped via a linear ordinal compare over up to 200 rows, so a forged 5000-signal stream with ~400 KB near-identical package ids cost minutes of CPU per GET sessions/{id}/reducer-verification while ReducerVerifier held all decoded payloads (~GBs) live; keys are now bounded BEFORE the dedupe scan (forged near-duplicates collapse to one row), Scope normalised to machine/user, and the same bound applied to failed app ids, HelloOutcome, ImeMatchedPatternId, EspAdvisoryFailureCategory and RJ product version/channel incl. WithVersionOverride — never truncating real telemetry (registry key names ≤ 255, GUIDs, enum-like strings); the agent adapter bounds packageId/version at the source; ReducerVerifier replays decode-fold-discard (head-signal check before the journal so stubbed streams stay silent, mid-stream truncation and count-imbalance semantics unchanged, pinned by tests); ISignalRepository.QueryBySessionAsync carries a cumulative PayloadJson budget (SignalQueryLimits, 32 M chars) reflected in the truncated flag of sessions/{id}/signals and reducer-verification; no ingest cap — stored signals stay verbatim

Oliver Kieselbach 3c8ef02191 feat(agent): RealmJoin self-update is observed and reported as realmjoin_autoupdate_detected — realmjoin_detected read the version once from RealmJoin.exe, but the tray AppUpdater often replaces the MSI-shipped binary on its first start minutes after detection (gktatooine 946ccbd6: 4.21.4 -> 4.21.18, whole deployment ran on the new build while the timeline and RealmJoinFacts kept 4.21.4); the updater's only registry write is HKLM\...\Uninstall\RealmJoin (DisplayVersion/InstallDate), so RealmJoinWatcher arms a RegNotifyChangeKeyValue watcher there once Detected fired (appearance-watch on the Uninstall parent until the tray creates the entry), re-reads the binary version after a 2 s debounce (DisplayVersion fallback while the file is locked, channel from baseline) and emits the Info event {previousVersion,newVersion,releaseChannel} plus the typed RealmJoinAutoUpdateDetected signal, whose reducer overrides RealmJoinFacts.ProductVersion/ReleaseChannel (WithVersionOverride) and touches neither gate, deadline nor LastActivityUtc; unreadable baseline at detection is seeded silently; portal device card prefers the updated version ("auto-updated from X"); event registered in Constants/resource-catalog/shared-manifests with replay fixture and watcher/adapter/reducer tests

Oliver Kieselbach 44dd8161df fix(agent): ImeProcessWatcher verifies process identity before attaching and re-arms discovery after an exit — it attached to the first IntuneManagementExtension name match, so a standard user starting a renamed binary during AccountSetup could forge an ime_process_exited Warning and mute the real signal for the rest of the session (CWE-807), and even a legitimate IME service restart was never watched again; ImeProcessIdentity requires session 0 + image under the IME install root (QueryFullProcessImageName, cross-bitness), prefers the oldest trusted candidate, logs untrusted matches once per PID, and OnImeExited restarts the discovery timer (ReferenceEquals guard against duplicate events)

Oliver Kieselbach 7a3516e570 feat(observability): IME pattern-drift loop — nothing the log tracker skips or stops matching stays silent: the agent keeps cumulative tracker health counters and a per-pattern match histogram (restart-safe in ImeTrackerState), reports ime_* keys in agent_metrics_snapshot (files tailed, backlog bytes, lines read, matches, oversized/timeouts/budget breaks/held tails/unanchored), raises a one-shot immediate-upload ime_tracker_degraded Warning on the first pass that skipped work, and emits ime_pattern_hits at termination (every enabled pattern, zeros included, IME version); the backend folds the histogram into the permanent per-IME-version ImePatternStats table (built-in IDs only, plausible version only, one partition read + one transactional batch) and evaluates drift without a hard-coded list — baseline = the version with the most reporting sessions (≥100), expected = ≥80 % hit rate there, drift = an expected pattern matched in none of ≥25 sessions on a newer version — raising ImePatternDriftSuspected once per version×pattern (ETag-stamped, dual-registered in the web ops-event list with a new guard test); GET metrics/ime-pattern-health (GlobalReadOrAdmin) + Global Admin → Metrics → IME Pattern Health matrix (drift/silent/low/few cells, open alerts, retired patterns) + session-page "IME Tracker" rows (latest snapshot by max sequence) + MCP get_ime_pattern_health (GA/Reader)

Oliver Kieselbach 84d06e1cf6 fix(security): LocalAdminAnalyzer never exempts a logged-in local SAM account from the shutdown scan (CWE-807) and matches built-ins by well-known RID so localized Guest/Administrator are not flagged
The shutdown run allowed every logged-in user (explorer.exe owner) dynamically, so a backdoor account created after the startup scan and signed in before enrollment completed was scored 0. The WMI inventory is now read first and a logged-in name that is a local account is rejected for the account and the profile check (reported as logged_in_local_accounts); only Entra/domain identities — the only ones seen in real sessions — remain dynamically allowed for their profile folder.

Built-ins are recognised by RID 500/501/503/504 on the machine SID in addition to their English names: since disabled accounts are inventoried (88dfd331), localized Gast/Invité/Administrateur would otherwise flag every non-English device. kioskUser0 (Assigned Access autologon) joins the built-in list; the profile check skips junctions and $<32 hex> folders (cannot be an account name, pure payload noise). ANALYZE-ID-002 1.3.0 explanation mentions the new field.

Oliver Kieselbach a47e94f9a5 fix(security): diagnostics packager reads every file through a handle validated against its pinned source folder; a subdirectory swapped for a junction between enumeration and open is skipped instead of copied
The path guards, the enumeration's reparse-point skip and the per-file attribute check all judged path strings, while the FileStream feeding the ZIP opened that string later (after earlier files were compressed). Under any recursive source folder a local user can write to, a subdirectory turned into a junction in that window made SYSTEM copy the junction target into the tenant-uploaded package.

PinnedSourceFolder holds each section folder open for the whole section (final path must equal the validated path, 8.3-expanded; FILE_LIST_DIRECTORY without delete share, so NTFS refuses renaming it or any ancestor) and opens each candidate with FILE_FLAG_OPEN_REPARSE_POINT, requiring the handle's final path to be exactly <canonical folder>\<relative path>; the archive is fed from that same handle. Manifest: FOLDER REJECTED (...) / SKIPPED (resolved outside validated folder) / FAILED (open). The race is pinned by a test that swaps the directory from the BeforeSourceFileOpen seam; on the previous code the same test copies the junction target.

Oliver Kieselbach 1733f4fd48 fix(agent): SignalIngress worker re-entrancy — never block the single consumer on its own post
EffectRunner posts ClassifierVerdictIssued from inside DecisionStepProcessor.ApplyStep,
i.e. on the SignalIngress worker thread. With the bounded channel (256) full, Post's
back-pressure slow path blocked the channel's only consumer as a producer: nothing could
ever drain, every collector Post blocked behind it, and the whole decision/monitoring
pipeline froze silently until the max-lifetime watchdog.

Post now detects a call from the worker thread itself and routes the item to a
worker-local follow-up queue that WorkerLoop drains (iteratively, ahead of the channel)
right after the current item. Same processing path — ordinals, SignalLog, emit,
reduce, ApplyStep — just never blocking. Worker posts are accepted during the Stop
drain too, since the verdict belongs to the step being finished. ReentrantPostCount
exposed for observability/tests.

Tests: full channel + worker post releases a blocked foreign producer and processes the
verdict before the next channel item (fails against the previous code by hanging);
follow-up chain drained in order without recursion; verdict posted during Stop drain is
not lost. Docs: agent/decision-engine.md, agent/overview.md, log.md.

Oliver Kieselbach fc46b4c78e feat(security): session-owner binding stage 1 (shadow) + dormant agent session rotation
Agent endpoints authenticated per tenant but authorized session writes on a caller-supplied
session id. Sessions rows now carry the creating device identity (cert thumbprint + Intune
device id from the CN, or bootstrap code + serial) in primary-only Owner* columns.
SessionOwnershipPolicy evaluates register / telemetry / error-report requests against it;
SessionOwnerBindingObserver records the outcome on the request row, as a warning and as a
throttled SessionOwnerMismatch ops event. Nothing is rejected in this stage.

Agent: errorCode parsing on 401/403, one-shot session rotation on session_owner_mismatch
without feeding the auth-failure tracker, spool drop, agent_started.sessionRotated.

Oliver Kieselbach c18de5d76c fix(security): drop client-writable certificate header; bootstrap routes token-only, fail-closed
SecurityValidator accepted certificate bytes from X-Client-Certificate when X-ARR-ClientCert was
absent. That header is client-writable, and certificate content alone carries no proof of private-key
possession — the TLS handshake does. On platform-cert-enforced routes the fallback was unreachable,
but /api/bootstrap/* is excluded from the platform cert requirement and an EMPTY X-Bootstrap-Token
passed the function gate (Headers.Contains) while the validator treated it as no token and fell
through to the certificate stage, where the fallback header was parsed (live-verified 2026-08-29).

- Only X-ARR-ClientCert is read; the platform strips inbound copies even on excluded paths.
- IsBootstrapRoute (path prefix mirroring the exclusion entry): missing/empty token or unwired
  BootstrapSessionService => 401 before the certificate stage.
- GetBootstrapToken treats an empty header as absent; the three bootstrap functions use it.
- Tests: BootstrapRouteFailClosedTests. Docs: client-cert-tenant-binding.md transport section.

Oliver Kieselbach a306cd9e40 feat(security): resolve admin identity bindings automatically at grant time; per-tenant bindings panel
Granting a cross-tenant role is "type the UPN" again. AdminIdentityResolver derives the home
tenant + object id from sign-in history (UserActivity: both values came from validated tokens,
most recent sign-in wins), falls back to the UPN domain of an onboarded tenant (tid only, oid
pinned on first sign-in), and never guesses when a UPN was seen under two tenants. Only a
never-seen domain yields 422 HomeTenantUnresolved, on which the portal shows a home-tenant picker.

- IMetricsRepository.GetSignInIdentitiesByUpnAsync (filtered UserActivity scan, grant-time only)
- Grant endpoints: homeTenantId/objectId optional overrides; bindings dropped from the list bodies
- Web: identity fields and binding pills removed from the delegated / tenant-group forms;
  new collapsed "Identity bindings" panel in Tenant Management -> Edit Tenant Configuration
  (bindings homed in that tenant; inline edit / remove via global/identity-bindings)
- Tests: AdminIdentityResolverTests; grant validation now accepts an absent home tenant

Oliver Kieselbach 8ec8524252 fix(security): bind platform and delegated roles to the immutable Entra tid+oid, not the UPN string
GlobalAdmins, DelegatedAdmins and TenantGroupAssignments resolved their role from the
upn/preferred_username claim alone while the API accepts tokens from every Entra tenant, so a
genuine token minted in a foreign tenant (re-registered domain) or by a recycled UPN in the home
tenant inherited platform admin.

- New AdminIdentityBindings table: RK = UPN -> home TenantId + ObjectId; in TableNames.All,
  CriticalBackupTables and the full-restore-forbidden auth set; offboarding wipes bindings homed
  in the offboarded tenant
- AdminIdentity (upn + tid + oid) is what GlobalAdminService.GetGlobalRoleAsync and
  DelegatedAdminService.GetScopeAsync resolve on; order row -> binding -> Pro gate, fail-closed
  (no oid / no binding / tid or oid mismatch => no role), mismatches logged at Warning
- Object id pinned on the first sign-in from the bound tenant (ETag-conditional, verified against
  the stored winner); a foreign-tenant token can never claim the pin
- Grants (auth/global-admins, global/delegated-admins, tenant-group assignees) require
  homeTenantId (+ optional objectId) and answer 409 instead of re-homing a bound UPN;
  GET/PUT/DELETE global/identity-bindings is the audited rebind surface
- RequestContext.ObjectId; throttle identity prefers oid so shared UPN strings across tenants no
  longer collide in one rate-limit bucket
- Web: home tenant / object id fields on the grant and assign forms, per-UPN binding pill
- Tests: binding verdict matrix + race semantics, middleware-level denials for foreign-tenant and
  recycled-UPN tokens; OKF doc docs/backend/admin-identity-binding.md

Legacy role rows are inert until their binding is seeded - seed before deploying the backend.

Oliver Kieselbach 9b4222e729 fix(ime-archive): verify MSI ProductVersion and walk primary/secondary/hotfix hosts before archiving
Microsoft serves IME from several versionless hosts carrying different rings at once
(secondary = 1.104.102.0 while hotfix = 1.105.103.0), so "new version == what the
canonical URL serves" filed a 1.104 package under 1.105.103.0. The archiver now spools
each candidate, reads ProductVersion with a managed CFB/MSI reader (Linux host, no
msiexec) and uploads only a match; no match ends as Failed:VersionMismatch. A later
sighting with a version-authoritative CSP URL re-queues an unarchived version at most
once per 24 h (MsiArchiveUpdatedAt + Queued stamp).

Oliver Kieselbach cf76c4338f feat(vuln): manual "Refresh NVD Cache" and "Sync EPSS" with their own last-sync lines
The admin Data Sync Status only offered KEV and MSRC; the NVD stale-row refresh and the EPSS
re-score ran on the nightly timer alone. Both walks move out of the timer into
VulnerabilityCacheRefreshService (singleton, one in-flight slot per walk) so the buttons and the
nightly run share one code path and stamp the same timestamps (NvdCacheLastRefreshUtc — only for
a walk that reached every stale row; EpssLastSyncUtc). POST vulnerability/sync-nvd starts the
minutes-long, rate-limited NVD walk in the background and answers 202 (409 while running); the
page polls sync-status (nvdRefreshRunning, nvdLastRun) every 10 s meanwhile. POST
vulnerability/sync-epss runs synchronously and returns the counts. The timer skips a slot a
manual run holds instead of queueing a duplicate. Shared manifest regenerated for the two new
AdminConfiguration fields.

Oliver Kieselbach a6184f165b feat(vuln): FIRST EPSS as fourth source, act/attend/track priority, CVSS vector; never cache a refused NVD answer
EPSS: EpssApiClient (api.first.org, 100 ids per batch, unauthenticated, fail-soft). Score, percentile
and date live on the cached CVE — one batch per CPE fill, every cve_* row re-scored by the nightly
sync, only changed rows rewritten and with their original CachedAt. CveIndex carries EpssScore (max,
absent when unscored) and Priority; TopCve exposes both. CvePriority: act = CISA KEV, attend =
EPSS >= 0.1 or CVSS >= 9.0, track = rest — riskLevel/overall_risk semantics unchanged.

NVD throttle: Polly already retried 429s; the defect was that a refused answer came back as an
empty response and was cached as "0 CVEs" for seven days (also the negative auto-resolve cache).
NvdFetchResult separates answered from refused; nothing persists a refusal; a 429 opens a
process-wide cooldown (Retry-After capped at 120 s, else 30 s) so a run fails fast instead of
paying a retry chain per software item; hard-expired rows keep serving meanwhile. The NVD->cache
projection and the row builder are now single functions shared by the live fill and the sync.

CVSS v3 vector string persisted and shown. Portal: EPSS column + pill, priority pill, vector line;
exposure panel pills. MCP tool descriptions and the CVE-audit prompt name the fields. Terms
attribution + privacy page updated in the same change. OKF doc backend/vulnerability-correlation-sources.md.

Oliver Kieselbach 1a4e13f0e9 feat(mcp): implement MCP spec 2026-07-28 (SDK v2 dual-era handler) and Client ID Metadata Documents
Wire protocol: replace @modelcontextprotocol/sdk 1.30 with @modelcontextprotocol/server + /node 2.0.0
(zod 4). One per-request factory (mcp-server-factory.ts, extracted from index.ts) serves both eras
through mcp-http.ts: 2026-07-28 clients via createMcpHandler (legacy:'reject', JSON response mode,
server/discover, Mcp-Method routing), 2025 clients through the existing stateless transport with
enableJsonResponse — routed on the SDK's own isLegacyRequest predicate, because the built-in stateless
fallback would answer every current client with SSE and lose the gzip win. Capabilities now declare
listChanged:false explicitly; cacheHints stamp ttlMs/cacheScope:'private' on discover/list results
(5 min) and resource reads (60 min) — the catalog is role-dependent, so never public.

Authorization: advertise client_id_metadata_document_supported; an https client_id is a Client ID
Metadata Document resolved by cimd.ts (URL-shape checks, SSRF gate on every resolved address before any
request, no redirects, 5 s / 16 KB caps, exact client_id match, bounded redirect_uris, 10-60 min cache).
The requested redirect_uri still has to pass the dynamic-registration allowlist; HMAC-signed DCR
client_ids remain the fallback. Field limits moved to oauth-limits.ts (no import cycle).

Tests: mcp-http.test.ts drives the real v2 client over loopback HTTP in both eras and pins role parity;
cimd.test.ts / oauth-cimd.test.ts cover recognition, SSRF, validation, cache and the router paths.
Package 1.5 -> 1.6. OKF doc docs/mcp/protocol-eras-and-cimd.md; mcp-oauth-flow.md updated.

Oliver Kieselbach bf156cf862 fix(backend): CMTrace skew tripwire ignores backlog-replay bursts via per-sample grid conformity
CmTraceTimeSkewRegression fired 7x in its first soak week; every checked case
was a relaunched agent re-tailing the IME log and uploading one burst holding
most of the session's IME samples with a continuum of ages whose median hit the
15-minute grid by chance. The tripwire now also requires >= 80 % of the IME
deltas (relative to the other side's median) to individually sit within 2 min of

Oliver Kieselbach 0eaa3527f9 feat(validation,web): device association validator generally available
Microsoft released Windows Autopilot device association on 2026-08-25. The
DevPrep association lookup leaves shadow mode and becomes an accepting method
of the device-validation gate (after Autopilot and Corporate Identifier, before
the Cloud PC fallback; ValidatedBy = DeviceAssociation, transient -> 503). The
toggle is no longer Global-Admin-only: backend PUT revert and GaOnlyFields
dropped, settings toggle shown to every tenant admin under Device Preparation
with the shared consent rule. Landing hero carries a release pill linking to
the docs; dashboard tip added.

Oliver Kieselbach 040e411958 feat(classification,calibration): rule 5a completed-assumed, max-lifetime grace skip, drift-radar floors
First real calibration read (2026-08-27, four days instrumented) drove three
data-backed changes:

- Rule 5a: past grace (or with the agent provably gone), Device Setup done +
  real-user desktop + zero app_install_failed reconciles to Succeeded
  "completed (assumed)" (r5_assumed). r5-Incomplete devices re-enrolled at
  2.6% - the succeeded background, not the ~29% failure level - and the
  sampled desktop half had clean app records. No desktop or any failed app
  stays Incomplete; rule 4 remains the immediate desktop+Hello reconcile.
- Rule 5 skips the AwaitingUser grace once either max-lifetime watchdog shape
  (enrollment_failed/agent_timeout, agent_shutting_down/max_lifetime) is in
  the stream: all five observed maxlife:r5_awaiting parks expired unhealed
  while live-agent parks upgraded 7/26. The maxlife ingest appends its
  trigger event to the read stream so the fact is never missed; late
  telemetry still heals a terminal verdict. WhiteGlove rule 1b keeps its
  park (its one episode healed).
- Drift radar: MinWindowHits raised to 10 (a 3-hit episode survived as
  noise), per-path share regression now needs >=5 baseline hits (new or
  renamed vocabulary cannot "regress"), and rule-shaped legacy:* paths count
  into the silence/classifier-verdict group sums on both sides of the
  2026-08-23 instrumentation cutover - dissolving the lift-124 silence
  artifact. Episodes below the fire floors clear themselves.

Backend only; the new path appears in the calibration matrix dynamically.

Oliver Kieselbach 42c45cf567 feat(admin,backend): find a tenant by its notification or contact email
A delivery log names only the recipient, never the tenant the welcome mail was
for. The tenant console's search now matches the notification and contact
address as well as domain and tenant id; the quoted exact mode is unchanged, and
no other address is searchable (an admin UPN never receives platform mail and
would only widen the PII surface of the list).

The addresses live in PreviewWhitelist, not on the tenant config, so a new
GA/Reader-only GET /api/preview/notification-emails returns them as one map --
a single cross-partition scan instead of a point read per tenant. Both sides
join on the lowercased tenant id (address rows carry the JWT tid, a config
PartitionKey's casing is not guaranteed) and matching is case-insensitive,
because stored addresses keep the casing the user typed.

The map is best-effort in the portal: a failed read costs only the
search-by-address, never the tenant list. Addresses stay out of the list rows --
they are a search key, and remain visible in the tenant editor.

Match rules moved out of the component into tenantSearch.ts with unit pins, and
a catalog test pins that the plural route does not resolve to the per-tenant
entry one character away (which would demand a tenantId the route does not
carry, and hand a delegated caller a rescue path into the whole map).

Deploy: backend before web.

Oliver Kieselbach 51f2dabc8c feat(web): explain the blank WiFi signal in the network timeline
The timeline showed WiFi segments with an SSID and no signal, and an "Avg WiFi
signal" stat that simply vanished — on a location-gated device that reads as a
product defect rather than the Windows 24H2 gate that caused it.

No agent change was needed: buildSegments already merges every wifi_signal_info
into the WiFi segment covering its timestamp, so wifiDataLimitedReason rides in
with the sample that was already being read.

- NetSegment.dataLimitedReason, filled from the sample.
- Segments that never got a sample of their own (a mid-session reconnect emits
  no wifi_signal_info) inherit it: the gate is a device-level setting and cannot
  flip during an enrollment. A segment WITH a real reading is never overwritten
  — pinned by a test.
- Tooltip: "Signal: unavailable — Location services off on this device" where
  the percentage would be.
- Stats row: "Avg WiFi signal: n/a (Location services off)" instead of dropping
  the row.

network_state_change is deliberately left alone. That event has never carried
signalPercent or radioType — NetworkChangeDetector collects them into its
snapshot for change detection, but only before_/after_wifiSsid reaches the
payload — so there is no absent field there for a reason to explain, and the
SSID it does carry is unaffected by the gate. Adding it would ship a field
nothing reads.

Verified: web tsc + eslint (0 warnings) + vitest 893/893.

Oliver Kieselbach 0f9a77c848 feat(agent,web,mcp): surface the 24H2 location gate instead of only logging it
A missing WiFi signal reading is indistinguishable from a bug unless the payload
says why, and the device-level location setting is not something an admin would
think to check. Since 058248d9 the SSID survives the gate via the WinRT tier —
but signal, radio and channel silently vanish with no explanation anywhere.

When the WinRT tier wins AND the native tier reported rc=5, wifi_signal_info now
carries wifiDataLimitedReason = "location_services_off" and the event message
gains "— signal unavailable, Location services off", so the reason reads straight
off the timeline. The portal's WiFi card matches that literal and names the
Intune setting that restores the full payload.

The claim is evidence-only: any other native failure (no WLAN service, no
connected interface) leaves the field null rather than blaming a privacy setting
we did not observe. IsLocationGateDenied is the single predicate, pinned at its
boundaries (rc=5 yes; rc=50, rc=5023, rc=1062 no), and the literal is pinned as
the published agent/portal/MCP contract.

New wifi_signal_info group in the MCP DEVICE_PROPERTIES_CATALOG, so a fleet can
be sized before anyone changes a policy:
search_sessions(deviceProperties: {
  "wifi_signal_info.wifiDataLimitedReason": "location_services_off" })

Backend is untouched — the event payload is opaque DataJson with no projection.
network_state_change and the network timeline deliberately do not carry the
reason yet; that is a second payload plus web change for no extra insight.

Verified: build 0 warnings, agent suite 2553/2553, web tsc + eslint (0 warnings)
+ vitest 889/889, MCP tsc.

Oliver Kieselbach 058248d95c fix(agent): read WiFi SSID via ungated WinRT API — 24H2 location gate
wifi_signal_info was missing on most Windows 11 24H2+ WiFi enrollments
(build 22631 3/3, 26100 37/178, 26200 43/95 over n=276 sessions since 08-01).
Not a parser or language problem: every event that exists carries a full SSID,
so the failure is binary at the reader level.

Since 24H2 Windows gates WlanQueryInterface with
wlan_intf_opcode_current_connection — the only opcode we use — behind
precise-location consent and returns ERROR_ACCESS_DENIED. The consent prompt
only fires for a process in the user's context outside System32, so the agent
(SYSTEM, session 0, before the OOBE privacy page) is denied silently, and it
resolves consent from the HKLM ConsentStore because the S-1-5-18 hive has none
— while the interactive user on the same machine reads the SSID fine via the
per-user NonPackaged value. That is why it tracks the image's location setting,
not hardware, driver or language.

netsh wlan hangs off the same gate, so the 2026-07 netsh fallback and its
multi-language labels never covered the case they were built for; more labels
cannot fix it.

- New WinRtWifiSsidReader: Microsoft's documented replacement
  WlanConnectionProfileDetails.GetConnectedSsid (ungated, SSID only), bound via
  the CLR WinRT projection — no winmd, no NuGet, no csproj change — the same
  mechanism OobeStateReader already uses from the SYSTEM context.
- New WifiInfoProvider owns the tier order (native -> WinRT -> netsh) that both
  collectors had duplicated.
- The step diagnostics added in 2026-07 were logged at Debug while the default
  level is Info, so they never reached a field log. The all-tiers-failed case is
  now a Warning that decodes rc=5 into the location-gate explanation.

Signal, PHY and channel have no ungated source and stay null on tier 2;
deriving a percentage from GetSignalBars would fabricate precision.

Verified: build 0 warnings, agent suite 2542/2542, interop struct sizes measured
live (532/604), and the full WinRT chain resolves and returns the SSID under
net48.

Oliver Kieselbach d6895f2c7e feat(security): enforce cert tenant binding — reject cross-tenant certificates
The Intune roots the chain is pinned to are shared by every Intune tenant, so
a valid certificate only ever proved "issued by Intune to someone". Tenant
scoping rested on the device serial, which is printed on the chassis. A
Mismatch now returns 403.

Switched on against measured data, not a hunch: 35,684 requests across 32
tenants since the shadow telemetry landed, every one a Match, with the
Warning channel independently verified to be carrying other traffic so the
zero could not be a telemetry artefact.

Only Mismatch blocks, and the rule lives in one function so "what rejects a
request" has a single answer. ExtensionMissing, Unparseable and
RequestTenantNotAGuid mean "cannot tell" and are tolerated: the sample only
covers devices active in the window, so an older certificate or a
sovereign-cloud CA could still lack the extension, and rejecting on absence
would lock those devices out for something outside their control.
ExtensionMissing is the candidate for later tightening and has its own test
pinning the tolerance, so removing it must be a decision.

Evaluation fails open on its own exception — a defect on our side is not
evidence of a cross-tenant certificate. The 403 body does not echo which
tenant the certificate belongs to; that pair goes to the rejection log.

Device binding (stage 3) is untouched: still shadow, still Global-Admin-only.

Oliver Kieselbach c91d8d4501 fix(agent): complete enrollments with zero user-targeted apps instead of failing them
IME never writes its "Completed user session" line when the user has no
assigned Win32 apps - its zero-app branch returns before that statement
(ApplicationPoller.cs:713-721, identical in 1.80/1.83/1.97/1.104). So
ImeUserSessionCompletedUtc stayed null, every arm of
ShouldTransitionToAwaitingHello was unsatisfiable, and the 30-min
advisory_completion backstop resolved healthy enrollments as
esp_exit_without_completion_evidence. One tenant: 10 of 30 sessions in a week,
all false positives - DAD-validated desktop, Hello provisioned, RealmJoin still
installing. Every Succeeded session there carries ime_user_session_completed;
not one of the failed ones does.

IME-USER-SESSION-ZERO-APPS reads the line IME does write there and routes it
through the same OnUserSessionCompleted callback. That is IME's own verdict
rather than a weakened gate: the zero-app branch locks the ESP in with an empty
application list, and the sibling emit site returns ProvisioningComplete right
after logging it. Guarded to the AccountSetup phase so it cannot burn the
adapter fire-once flag on a pre-sign-in timestamp, and replayed on the phase
transition when the observation predates the phase marker. AreUserEspAppsSettled
accepts an empty app list only with that explicit observation, never on
emptiness alone.

Second, independent defect: advisory_completion (30 min) overran the RealmJoin
completion gate, which deliberately holds the session and carries its own
bounded resolution (60 min from detection, activity-extended, 4 h cap). One
session installed 25 RealmJoin packages inside the window, the last 2 min before
the failure, while completion_waiting still read "waiting on:
realmjoin_resolution". The handler now re-arms while that gate is closed and its
own deadline is still armed; convergence comes from the gate itself, which
always ends with an Outcome set.

ime_user_session_completed gains an evidence field (zero_user_apps_enumerated /
user_session_completed) - no new event type, so the Constants ->
resource-catalog -> shared-manifests triple stays untouched. The pattern ships
via the config API and reaches existing agents, where an unknown action is a
single Debug line; the behaviour needs the agent release.

Same gate the cert-device-binding shadow got in 35a3ed0c, applied to its

device off a handful of Graph calls, because the cache answered nearly every
request and the log sat outside it.

cached instance, so the first real lookup is never mistaken for a cache hit
and dropped. Transient outcomes are not cached and keep logging every time.

Oliver Kieselbach 35a3ed0cfb perf(security): log device binding once per Graph lookup, not per request
Measured on the first live enrollment: 136 agent requests produced exactly
ONE Graph call, because the 30-minute positive cache absorbed the rest. So
the check is not a throttling risk (the per-request Autopilot serial
validator made 25 calls in the same window) and the positive TTL needs no
change — raising it would only delay noticing a wiped or removed device.

What the 136 requests did cost was 136 log lines all saying the same thing.
Gate the shadow log on ServedFromCache so it emits one line per real lookup.
Cached repeats carry no new information: the reported age just counts up
mechanically from the same enrolledDateTime. Outcomes that are never cached
(Transient, NoDeviceIdInCert) keep logging every time, which is what an
anomaly warrants.

AsCacheHit() copies rather than marking the shared cached instance, so the
first real lookup is never mistaken for a cache hit and dropped.

Oliver Kieselbach ea6a375c4b feat(security): cert-to-device binding, stage 3 GA-gated shadow
Tenant binding (stage 1) proves the client certificate was issued to this
tenant. It does not prove the certificate belongs to a device the tenant
still has: a cert lifted from a decommissioned machine keeps working.

IntuneDeviceBindingValidator resolves the Intune managedDevice id from the
certificate's Subject CN against the tenant's own managedDevices inventory.
Point-GET on managedDevices/{id} rather than an OData filter, so there is no
filter literal to inject into and a 404 is unambiguous. Cache/retry/transient
contract mirrors CloudPcDeviceValidator.

Shadow only, and visible only to Global Admins (same gate as the DevPrep
association preview) because the open question is a race, not an attack: a
device object can appear after the agent's first call. Every result carries
enrolledDateTime and the log line records enrolledAgeSeconds, so a device
created seconds before the request is distinguishable from a foreign cert.
Grep marker: CERT-DEVICE-BINDING-SHADOW.

The lookup is fire-and-forget like the DevPrep shadow so a cold Graph
round-trip never sits in the agent request path. That rules out stage 1's
request-row dimension (the row is written before the task finishes), hence
the Warning log; widening beyond preview should move to inline + dimension.

Needs DeviceManagementManagedDevices.Read.All, granted per tenant via the
customer script as feature IntuneDeviceBinding. The script's catalog,
ValidateSet and help block stay pinned to GraphFeatureCatalog by
GraphFeatureCatalogSyncTests (extended with the help-block case).

Oliver Kieselbach fb79c7711c fix(security): carry cert tenant binding on the request row, not a dead log line
Post-deploy verification of 249e39bc found zero AgentCertTenantBinding rows
across 32k agent requests. Cause: the Match outcome was emitted with
LogInformation, and worker-side ILogger below Warning never reaches App
Insights (provider default rule is Warning+, host forwarding of worker logs
is off). The bulk outcome was therefore invisible, which is indistinguishable
from the code never running — the shadow telemetry had no denominator.

Stamp every outcome onto the request row instead (FunctionContext.Items ->
RequestTelemetryMiddleware -> CertTenantBinding dimension). That row already
exists per request and is unsampled, so the denominator costs no extra
telemetry. Non-Match outcomes keep their Warning trace with full context.

FromCache existed only to sample the dead Match line and is removed with it.

Oliver Kieselbach 249e39bc68 feat(security): cert tenant binding, stage 1 shadow mode
A chain-valid Intune MDM certificate only proves "issued to some tenant" —
the pinned roots are shared by every Intune tenant. Tenant scoping rested
entirely on the device serial in the downstream validators, which is not a
secret. Bind the tenant stamped into the auth cert to the requested tenant.

The Entra tenant id sits in OID 1.2.840.113556.5.14 of the cert the agent
already presents for mTLS, so this needs no Graph call, no consent and no
agent release. Not 5.6 (Intune Account id, a different GUID) and not 5.4
(device id, stored as 16 bare bytes) — the decoder handles both encodings
and now lives once in Shared, used by agent and backend.

Stage 1 observes only: ObserveCertTenantBinding returns void and swallows
its own exceptions, so it cannot fail an otherwise valid request. Match is
logged only on cert-cache miss, keeping the denominator without per-request
volume. Grep marker for stage 2: CERT-TENANT-BINDING-SHADOW.
