From 830a27bb704f3b829d854b6bd85a92e4dc704ba1 Mon Sep 17 00:00:00 2001 From: Oliver Kieselbach Date: Mon, 20 Apr 2026 13:29:19 +0200 Subject: [PATCH 01/61] refactor(decisioncore): add DecisionCore shared library scaffolding (M1) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New netstandard2.0 project src/Shared/AutopilotMonitor.DecisionCore/ with 14 scaffolding types across Signals/, State/, Classifiers/, Engine/. Agent.Core and Functions reference the library without call-sites; the full solution builds 0 errors, 0 warnings. DecisionEngine.Reduce is an intentional NotImplementedException stub — M3 fills in the partial-class reducer. Invariants wired into the scaffolding: - Immutable DTOs (sealed + get-only + With-methods) per L.3 - Pflicht-Evidence validation in Evidence ctor per L.5 - KindSchemaVersion enforcement per L.6 - AssemblyVersion 2.0.0.0 as ReducerVersion source per §2.10 Architecture principles L.1–L.18 extracted to .claude/architecture-principles.md as persistent Claude-session context. Plan: plans/REFACTOR_AGENT_V2.md §4 M1. Zero runtime risk.

On every +architecture-relevant plan change, both locations are updated in sync. + +The principles outlive this plan — they carry the design substance we do not want to +re-derive every time. They are **not nice-to-haves**, they are review criteria: any code +change that violates a principle is either (a) a bug, (b) a reason to change the principle +(with user sign-off), or (c) an explicitly documented exception with rationale. + +--- + +## L.1 Truth Hierarchy (immutable) + +`SignalLog` (input) → `Journal` (decisions) → `Snapshot` (cache) → `Projections` (derivable). +No projection patches backwards into the journal or the signal log. On inconsistency, the +lower layer always wins (e.g. discard the snapshot, do not "repair" the signal log). + +## L.2 Event Sourcing as Foundation + +`SignalLog` is the only input truth. The reducer is pure: +`(oldState, signal) → (newState, transition, effects)`. The backend can re-derive at any +time from `SignalLog`. Replay yields the same `Journal` content. + +## L.3 Immutable State + +All DTOs in the decision core are `sealed` with get-only properties. No in-place mutation. +"Change" = new instance via `With…` method. This is the difference between "purely testable" +and "subtle heisenbugs". + +## L.4 Hypothesis Model instead of Flow Plugins + +Fuzziness is constitutive (White-Glove, enrollment type, device-only). A single reducer with +hypothesis fields (`Unknown/Weak/Strong/Confirmed/Rejected`), organized by scenario in partial +classes. **No** plugin runtime, because clean flow boundaries do not match reality. + +## L.5 Evidence Determinism + +Signal-log determinism is guaranteed: same log → same outcome. Every signal carries an +`Evidence` record with `Kind` (Raw / Derived / Synthetic) and mandatory fields. A signal +without evidence = adapter rejection = bug. + +## L.6 Signal Schema Versioning + +Every `DecisionSignalKind` has a `SchemaVersion`. The reducer dispatches on +`(Kind, SchemaVersion)` — old versions stay replay-capable. A new version or a new kind +without a replay fixture in `tests/fixtures/signal-kinds/{kind}-v{n}.json` = merge block. + +## L.7 Timer Monopoly + +Only the Deadline Scheduler (the EffectRunner role) holds decision-relevant timers. Collectors, +signal adapters and the orchestrator must not. `Task.Delay` or `new Timer(...)` in those +layers with session-state impact = merge block. `IClock` interface + virtual clock for +testability. + +## L.8 Classifier as Post-Hook Kernel Service + +`IClassifier` interface, swappable. The `ClassifierVerdict` flows back into the log as a +synthetic `ClassifierVerdictIssued` signal. `InputHash` (SHA256 over classifier-relevant +snapshot fields) is the anti-loop guard. Classifiers are not baked into the state machine. + +## L.9 Clean-Agent Principle on Refactors + +For structural refactors: build the new project in parallel to the legacy one, do not flag- +route inside the same process. Strict separation rule: no direct reference to legacy +projects. Code is copied, not shared. Legacy runs out, then gets removed. + +## L.10 Generic Telemetry Transport + +One spool for all telemetry types (events, signals, decision transitions). `TelemetryItemId` +is the type-agnostic upload cursor; the type-specific counters (`Event.Sequence`, +`SignalOrdinal`, `StepIndex`) remain storage / UI / reducer semantics. Drain guarantee: +"coordinated + idempotent + resumable" — **not** cross-table atomic, which is not achievable +with three separate tables anyway. + +## L.11 Separation: Agent Lifecycle vs Session State + +`DecisionState` is session-pure. Agent-process flags (crash, admin actions, boot time, +heartbeat status) live separately in `agent-lifecycle.json`, managed by the orchestrator, +never by the reducer. Prevents replay dilution by lifecycle events. + +## L.12 Flush-on-Append Persistence + +No batching of append operations. `FileOptions.WriteThrough` plus an explicit +`FlushAsync(flushToDisk: true)` per append. Every successful `Append` return means: on disk. +Durability > performance in the crash-prone OOBE context. + +## L.13 UI Primacy — End-Users vs Dev Tooling + +Product views (EventTimeline, PhaseTimeline) stay slim and stable. Debug / analysis tools +(Inspector with DecisionGraph, SignalStream, VerifierReport) live on their own subpage behind +an `adminMode` gate. The session-detail page does not get overloaded with dev components. + +## L.14 Forward Compatibility by Default + +Enums via `StringEnumConverter` + `UnknownFallbackEnumConverter` (unknown values → default, +never crash). New schema fields are nullable. The `ReducerVersion` stamp per journal row +allows older backends to read newer rows. Deletions only after a major version bump with +user sign-off. + +## L.15 Test Discipline + +Flow / scenario tests are prioritized over structural tests. Coverage targets per component +(DecisionCore ≥95 %, classifier 100 %, backend functions ≥85 %). A missing fixture for a +scenario = merge block. CI threshold check is a build failure, not a warning. + +## L.16 Fail-Safe Reducer Exceptions + +Exception in the reducer → `DecisionTransition` with `DeadEndReason=reducer_exception`, state +unchanged (fail-safe, never destroy state). Signal counts as processed (no retry loop). After +five consecutive exceptions → the orchestrator emits +`enrollment_failed(reason=reducer_instability)`. + +## L.17 Effect Error Handling by Class + +Three effect classes with their own strategy: + +- **Transient** (retry with exponential backoff 100 ms / 400 ms / 1600 ms): + `EmitEventTimelineEntry`, `PersistSnapshot` +- **Critical** (session abort, e.g. on timer-register failure): `ScheduleDeadline`, + `CancelDeadline` +- **Optional** (best-effort, classifier exception → `Inconclusive` verdict, no abort): + `RunClassifier` + +Every effect failure is logged as a `DecisionTransition`. + +## L.18 Implementation Discipline + +- **R1** Pre-flight plan check before every work step +- **R2** Delegate self-contained sub-tasks **and exploration** to subagents (Anthropic + recommendation: preserve main-context window on large refactors — quality assurance) +- **R3** Real verification (DB round-trip, index dual-write, agent signal emission) — no + "it compiles and runs" +- **R4** The plan is authority — deviations require user sign-off +- **R5** Out-of-scope items land in `tasks/todo.md`, not in memory +- **R6** High test coverage is a prerequisite for future refactorability, not a nice-to-have +- **R7** Code-structure discipline: small files (guideline ≤300 LoC), clear folders, partial + classes by scenario, check in with the user on any uncertainty (placement, naming, scope) + +--- + +**Maintaining these principles:** On every architecture-relevant plan change, the +corresponding L.n points are updated here **and** in [plans/REFACTOR_AGENT_V2.md](../plans/REFACTOR_AGENT_V2.md) +§7 in sync.

Grep-verified at commit time: zero `using AutopilotMonitor.Agent.Core` statements and zero Legacy ProjectReferences in the V2 tree. Per plan §2.11, kernel items (CompletionStateMachine, CompletionGuards, EnrollmentTracker*, Flows/*, WhiteGloveClassifier, WhiteGloveSignals, EnrollmentStatePersistence) are transitionally retained so the V2 tree compiles; M4 removes them when SignalAdapters + V2Orchestrator take over. Per user direction (feedback_v2_kernel_only_refactor): the V2 refactor replaces only the decision kernel. All peripheral capabilities — gather rules, analyzers, diagnostics upload, timezone, server-driven actions, summary dialog launch, env-var resolution, version checks, registry watchers, network/DO/performance telemetry, self-update, bootstrap→cert handover, self-destruct — are preserved verbatim via the bulk copy. Supporting M3 bring-up platform: - ReplayHarness (empty-stream deterministic, SHA256 hash over terminal state fields) in DecisionCore.Tests/Harness/ - Fixture scaffold under tests/fixtures/: committed anonymized directory with commit-policy README, plus gitignored enrollment-sessions-local/ for raw exports - tools/export-session-fixture.mjs with --help / --dry-run / --validate modes; real MCP wiring marked TODO(v2-m3) V2 bootstrap scripts scripts/Bootstrap/Install-AutopilotMonitor-v2(.|-dev).ps1 (committed, pure ASCII verified per feedback_ps1_ascii_only). V2 deployment scripts under scripts/Deployment/V2/ are gitignored (analog to Legacy). Test totals at M2 gate: 13 DecisionCore + 507 Agent.Core (unchanged) + 557 Functions (unchanged) = 1077 green.

No domain-specific reducer behavior yet; only kernel plumbing + a live SessionStarted / SessionRecovered / SessionAborted lifecycle path. Kernel (plan §2.5 / L.2 / L.3 / L.16): - DecisionEngine dispatches on (Kind, KindSchemaVersion) to partial-class handlers. Unhandled kinds produce a DeadEnd transition with a versioned reason string — never a throw, never a mutation. - Exception fail-safe (L.16): any handler exception is caught in the kernel, StepIndex + LastAppliedSignalOrdinal still advance (so the signal counts as processed and there is no retry loop), the transition records DeadEndReason="reducer_exception" + SHA256-short StackTraceHash. DecisionState is returned untouched beyond bookkeeping. - Shared helpers for Taken / DeadEnd transition construction keep partial-class handlers short and consistent. State (plan §2.3 / L.3): - Immutable DecisionState gets a mutable DecisionStateBuilder companion — reducer handlers use state.ToBuilder().WithStage(...).Build() to express "copy with changes" without retyping 20+ ctor arguments. - Fluent helpers AddDeadline (replace-if-same-name), CancelDeadline, WithCurrentEnrollmentPhase carry the most common reducer operations. Time (plan §2.6 / L.7): - IClock interface + SystemClock (wall-clock wrapper). The only way any decision-relevant code can observe time going forward. VirtualClock lives in the test assembly — never in shipping builds. Serialization (plan §2.8 / §2.15 / L.14): - Newtonsoft.Json added to DecisionCore (both net48 + net8.0 consume the same DTOs with the same converters). - UnknownFallbackEnumConverter maps unrecognized enum strings to a caller-provided fallback instead of throwing — lets an older backend read a newer DecisionCore's rows without crashing; the verifier will flag them as drift_tolerated in §2.10. - DecisionCoreJsonSettings registers fallback converters for every DecisionCore enum (DecisionSignalKind, EvidenceKind, HypothesisLevel, SessionStage, SessionOutcome, DecisionEffectKind, EnrollmentPhase). - SignalSerializer round-trips DecisionSignal JSONL with enforced Evidence.Identifier and Evidence.Kind — a line without Evidence throws just like constructor validation. Lifecycle (DecisionEngine.Shared.cs): - SessionStarted: anchors the first journal transition; rejects mid-flight replay (StepIndex != 0) with a DeadEnd instead of silently resetting hypotheses. - SessionRecovered: neutral bookkeeping in M3.0 — WhiteGlove Part 1 → 2 transition lands in M3.4 DecisionEngine.WhiteGlovePart2.cs. - SessionAborted: terminal, Outcome=Aborted, all deadlines cleared — orchestrator admin-action path (plan §2.7 audit). Test coverage (37 total): - VirtualClockTests (6) — monotonic clock, Delay instant-return - DecisionStateBuilderTests (5) — immutable semantics, deadline replace/cancel - SerializationTests (6) — round-trip, UnknownFallback both string + numeric - ReducerFailSafeTests (6) — null-arg, replay-on-active, unhandled kind, SessionAborted clears deadlines, ReducerVersion - SmokeTests (7) — smoke, updated: Reduce(SessionStarted) is a real transition, not a throw - HarnessTests (6) — empty-stream determinism, single-signal replay, unknown-kind DeadEnd at harness level - VirtualClock helper (instance) covered via Harness integration Suite totals unchanged elsewhere: 507 Legacy + 557 Functions. Full solution builds 0 warnings, 0 errors. Plan: plans/REFACTOR_AGENT_V2.md §4 M3 (sub-milestone M3.0 Foundation).

Handlers (DecisionEngine.Classic.cs): - EspPhaseChanged stage progression DeviceSetup -> AccountSetup; populates CurrentEnrollmentPhase + DeviceSetupEnteredUtc / AccountSetupEnteredUtc / FinalizingEnteredUtc facts; raises EnrollmentType hypothesis to Weak on AccountSetup. - EspExiting records EspFinalExitUtc; schedules HelloSafety (300 s); transitions to AwaitingHello and emits ScheduleDeadline. - HelloResolved records HelloResolvedUtc + HelloOutcome; cancels HelloSafety; completes session if Desktop already arrived. - DesktopArrived mirror of HelloResolved; completion when Hello already resolved. - ImeUserSessionCompleted raises EnrollmentType hypothesis to Strong; records matched pattern id. - AadUserJoinedLate HYPOTHESIS-ONLY (project memory feedback_aad_joined_late_not_completion). Records AadJoinedWithUser fact + annotates EnrollmentType reason. Stage unchanged, no terminal event. Regression guard test verifies From/To stage equality. Shared router (DecisionEngine.Shared.cs): - DeadlineFired dispatches on Payload[deadline]. HelloSafety timeout synthesizes HelloOutcome=Timeout and drives the same completion path as HelloResolved. Unknown deadline names cancel the deadline and record a neutral transition — forward-compat with M3.3 (ClassifierTick) / M3.4 (WhiteGlovePart2Safety). Constants: - DeadlineNames enumerates the 7 pflicht-deadlines from plan §2.6. - SignalPayloadKeys standardizes payload keys used by collectors and the deadline scheduler. Scenario harness + fixtures (tests/fixtures/enrollment-sessions/): - ScenarioTestBase locates repo root and wraps FixtureLoader + ReplayHarness. - userdriven-happy-v1.jsonl — 7 signals, terminal Completed / EnrollmentComplete / HelloOutcome=Success. - userdriven-hello-timeout-v1.jsonl — Desktop arrives before Hello, deadline fires at T+5m -> HelloOutcome=Timeout, Completed. - late-aadj-v1.jsonl — Late-AADJ mid-flight does not complete prematurely; session still completes normally via Hello + Desktop. Tests: 4 scenario tests in ClassicScenarioTests + determinism check. Total suite: 41 DecisionCore.Tests (was 37 at M3.0) / 507 Legacy unchanged / 557 Functions unchanged. Plan: plans/REFACTOR_AGENT_V2.md §4 M3 sub-milestone M3.1.

Handlers (DecisionEngine.SelfDeploying.cs): - DeviceSetupProvisioningComplete terminal. Cancels all deadlines, finalizes DeviceOnlyDeployment based on user-presence facts (AadJoinedWithUser, HelloResolvedUtc, DesktopArrivedUtc), raises EnrollmentType to Strong when no AccountSetup was observed before. - DeviceOnlyEspDetectionFired hypothesis-only update to DeviceOnlyDeployment=Strong(DeviceOnly). Stage unchanged; completion still requires explicit provisioning signal. Classic.cs extended: - First EspPhaseChanged(DeviceSetup) arms the DeviceOnlyEspDetection deadline (5 min window, plan §2.7). - EspPhaseChanged(AccountSetup) cancels it — UserDriven-v1 path. Shared DeadlineFired router routes the deadline to the SelfDeploying body. Scenario fixtures (tests/fixtures/enrollment-sessions/): - selfdeploying-happy-v1.jsonl — 3 signals, SkipUserStatusPage path. Terminal Completed with DeviceOnly hypothesis confirmed and no user-presence facts. - selfdeploying-esp-exit-unknown-v1.jsonl — 4 signals, deadline fires at T+5m and sets DeviceOnly before provisioning-complete arrives. Tests (SelfDeployingScenarioTests, 4 new): - SelfDeployingHappy terminal state + hypotheses - SelfDeployingHappy deadline cleanup - Device-Only ESP-exit-unknown deadline -> provisioning flow - AccountSetup on the Classic path cancels DeviceOnlyEspDetection (regression guard — UserDriven should never classify as DeviceOnly) InternalsVisibleTo added to DecisionCore for DecisionCore.Tests so the internal DeviceOnlyReasons tokens stay hidden from consumers while tests assert on them directly. Suite totals: 45 DecisionCore (was 41) / 507 Legacy / 557 Functions. Plan: plans/REFACTOR_AGENT_V2.md §4 M3 sub-milestone M3.2.

Classifier (WhiteGloveSealingClassifier : IClassifier): - Scoring ported 1:1 from Legacy WhiteGloveClassifier (same weights, same thresholds, same asymmetric-conservative rule: only Confirmed drives the WhiteGloveSealed stage). - Positive weights: ShellCoreWhiteGloveSuccess=80, SealingPattern=40, DeviceOnlyDeployment=15, SystemReboot=15. - Hard excluders (-100 each): AadJoinedWithUser, DesktopArrived, HelloResolved. Soft exclude: AccountSetupActivity=-40. - WhiteGloveSealingSnapshot is the classifier input type and computes a deterministic SHA256-short InputHash over WG-relevant fields only — so the anti-loop triggers on meaningful fact changes, not on unrelated state. Handlers (DecisionEngine.WhiteGlove.cs): - WhiteGloveShellCoreSuccess records fact; emits RunClassifier effect; arms ClassifierTick if not already. - WhiteGloveSealingPatternDetected mirror handler for the IME-pattern path. - ClassifierVerdictIssued applies the verdict to WhiteGloveSealing hypothesis; on Confirmed transitions to WhiteGloveSealed stage + Outcome=WhiteGlovePart1Sealed and emits the whiteglove_complete event. - HandleClassifierTickDeadlineFired (shared router) re-emits RunClassifier and re-arms itself unless terminal. ClassifierAwareReplayHarness (tests-only): - Loops per-step effects: any RunClassifier effect is resolved synchronously via the registered IClassifier; the verdict is wrapped in a ClassifierVerdictIssued signal and fed back into Reduce. Anti-loop skips the call when snapshot hash == state.WhiteGloveSealing.LastClassifierVerdictId. - Exposes ClassifierRunStats for regression tests. DecisionState extension: two new SignalFact fields capture the WG sightings (ShellCoreWhiteGloveSuccessSeen, WhiteGloveSealingPatternSeen). The classifier reads them via WhiteGloveSealingSnapshot. Scenario fixtures (4, committed-anonymized): - whiteglove-inline-v1.jsonl Confirmed on ShellCore alone (80). - whiteglove-signal-correlated-v1.jsonl Weak after pattern, ClassifierTick anti-loop-skipped, Confirmed after ShellCore escalates the score. - whiteglove-false-positive-v1.jsonl SealingPattern + late-AADJ hard- excludes -> Rejected; session still completes via Classic Hello+Desktop. - whiteglove-antiloop-v1.jsonl Single pattern + two ticks; runs=1, skipped_by_antiloop=2. Tests: 4 scenario tests in WhiteGlovePart1ScenarioTests, all passing. DecisionCore.Tests: 49 (was 45). Legacy 507 + Functions 557 unchanged. ReducerFailSafeTests + HarnessTests updated to use AppInstallCompleted as the still-unhandled sentinel (WhiteGloveShellCoreSuccess is now wired).

Classifier (WhiteGlovePart2CompletionClassifier : IClassifier): - Scoring rules NEW (no Legacy equivalent): each of the four Part-2 user signals (+25) — UserAadSignInComplete, HelloResolvedPart2, DesktopArrivedPart2, AccountSetupCompletedPart2. All four together hit the Confirmed threshold (100); missing one drops to Weak (75). - WhiteGlovePart2CompletionSnapshot implements the new IClassifierSnapshot interface; existing WhiteGloveSealingSnapshot was retrofit to the same contract so the harness anti-loop is uniform. Handlers (DecisionEngine.WhiteGlovePart2.cs): - SessionRecovered (Shared.cs) now bridges a WhiteGloveSealed state into WhiteGloveAwaitingUserSignIn and arms the 24h WhiteGlovePart2Safety deadline on the recovered signal's occurredAt. - Four Part-2 signal handlers (UserAadSignInComplete, HelloResolvedPart2, DesktopArrivedPart2, AccountSetupCompletedPart2) record facts + emit a Part-2 RunClassifier effect; facts arriving outside the AwaitingUserSignIn stage are recorded but no classifier runs (prevents stray Part-2 verdicts on non-sealed sessions). - WhiteGlovePart2Safety deadline handler terminates with Failed / enrollment_failed reason=part2_user_absent. - ClassifierVerdictIssued router extended to dispatch on classifier id — Part-2 verdicts route to ApplyWhiteGlovePart2Verdict; Confirmed triggers Stage=WhiteGloveCompletedPart2 + Outcome=WhiteGlovePart2Complete + whiteglove_part2_complete event. DecisionState: four new SignalFact? fields for the Part-2 signals (full builder parity). ClassifierAwareReplayHarness: anti-loop lookup now routes per classifier id (WhiteGloveSealing <-> WhiteGloveSealing.LastClassifierVerdictId; Part2Completion <-> WhiteGlovePart2Completion.LastClassifierVerdictId). Snapshot hashing works through the IClassifierSnapshot interface instead of a WhiteGloveSealingSnapshot type check. Scenario fixtures (committed-anonymized): - whiteglove-part2-happy-v1.jsonl seal Part 1, reboot, 4 Part-2 signals within minutes -> Confirmed + Part2Complete. - whiteglove-part2-stuck-v1.jsonl seal Part 1, reboot, 24h passes, safety deadline fires -> Failed / part2_user_absent. Tests (3 new in WhiteGlovePart2ScenarioTests): - Happy terminal state + hypotheses + all four facts + no residual deadlines - Stuck terminal state + Part-1 Confirmed remains, Part-2 Rejected with reason - Bridge check: after SessionRecovered(Sealed), Part-2 safety is active Suite totals: 52 DecisionCore (was 49) / 507 Legacy / 557 Functions.

Scenario fixtures (committed-anonymized): - hybrid-reboot-v1.jsonl ESP -> mid-phase reboot -> EspResumed -> AccountSetup -> Hello -> Desktop -> Completed. No WhiteGloveSealed path. - esp-terminal-failure-v1.jsonl ESP -> AccountSetup -> terminal failure -> Failed / reason= esp_terminal_failure_account_setup. Tests (EdgeScenarioTests, 5 new): - Hybrid reboot preserves stage, records reboot fact, completes normally without triggering WhiteGlove. - ESP terminal failure transitions straight to Failed. - Restart-recovery determinism: replaying the same JSONL twice yields identical FinalStepHash, Stage, Outcome and transition count. - Prefix-replay check: truncated log ends in the expected intermediate stage (simulates crash between signals). - Global sanity: every committed fixture (all 12) ends in a terminal stage — regression guard for any future reducer change. Suite totals: 57 DecisionCore (was 52) / 507 Legacy / 557 Functions = 1121 tests green. All 14+ scenarios from plan §R6 Szenario-Matrix pass through the reducer with the expected terminal outcome. This closes M3 (DecisionEngine-Reducer + Classifier-Kernel). M4 wires the SignalAdapter + EffectRunner + TelemetryTransport in the V2 agent runtime. Plan: plans/REFACTOR_AGENT_V2.md §4 M3 sub-milestone M3.5 — M3 complete.

New in V2.Core.Transport.Telemetry: - TelemetryItem + TelemetryItemKind + TelemetryItemDraft (immutable DTOs, StringEnum-converted Kind für forward-compat) - TelemetryItemSerializer (Newtonsoft-Ctor-Bind, JSONL) - TelemetrySpool (disk-backed JSONL queue, monotonic TelemetryItemId + SessionTraceOrdinal=TelemetryItemId for session items, WriteThrough+Flush per Enqueue, tail-corruption tolerance, restart recovery of counters) - UploadCursorPersistence (atomar temp+rename, parse-fail → cursor=-1) - IBackendTelemetryUploader + UploadResult (Ok/Transient/Permanent) — abstraction keeps orchestrator HTTP-agnostic; real BackendApiClient impl comes with M4.4 wiring - TelemetryUploadOrchestrator (Drain loop: batched, retry 100/400/1600ms backoff via IClock, permanent-fail skips retry, idempotent resume via spool cursor, exception→transient) - DrainResult + ITelemetryTransport interface New tests (+28, 56 total in V2.Core.Tests): - Spool: monotonic ids, session-scoped trace-ordinal, sofort-flush, Peek respects cursor + max, MarkUploaded regression no-op, restart recovery, corrupt-tail-scan tolerance - Orchestrator: happy drain, empty-spool noop, batching, 3-retry happy, exhaust→fail, permanent→no retry, exception→retry, resume after transient, cursor persists across restart, double-drain idempotent, cancel, dispose Testsuite: 1149 → 1177.

New in DecisionCore: - ClassifierVerdictLookup.LookupLastVerdictId(state, classifierId) — mapping classifier-id → hypothesis-slot. Shared between ClassifierAwareReplayHarness (refactored) and the production EffectRunner (DRY, L.15). New in V2.Core.Orchestration: - IClassifierRegistry + ClassifierRegistry (id→IClassifier, dup-detect) - ISignalIngressSink — abstraction for posting synthetic signals (real impl M4.4) - IEventTimelineEmitter — abstraction for EmitEventTimelineEntry (real impl M4.4) - EffectFailure + EffectRunResult — orchestrator-consumable dispatch result - IEffectRunner + EffectRunner - ScheduleDeadline/CancelDeadline → critical class: any exception sets SessionMustAbort=true with reason=timer_infrastructure_failure, stops processing subsequent effects - RunClassifier → optional class: anti-loop via ClassifierVerdictLookup + IClassifierSnapshot.ComputeInputHash(); exception → Inconclusive verdict posted via ingress, no abort - EmitEventTimelineEntry / PersistSnapshot → transient class: retry 100/400/1600ms via IClock.Delay, exhaust → failure recorded but no abort (§2.7b explicit „State unverändert, weiter im Flow") New tests (+18, 74 total in V2.Core.Tests): - Schedule/Cancel forwarding + abort on scheduler exception + stop-subsequent - Emit retry-then-success + retry exhaust (no abort, failure recorded) + failure does not block subsequent effects - Persist retry-then-success - Classifier happy (verdict signal posted correctly) + anti-loop skip + exception → Inconclusive verdict + unknown id → failure + missing snapshot - Batch-dispatch-order test, empty-batch test Testsuite: 1177 → 1195.

Sub-Split analog M3.x. New in V2.Core.SignalAdapters: - DesktopArrivalDetectorAdapter → DesktopArrived / DesktopArrivedPart2 - AadJoinWatcherAdapter → AadUserJoinedLate / UserAadSignInComplete (nur AadUserJoined-Event gemapped; PlaceholderUserDetected ist diagnostic, nicht Decision-relevant — dokumentiert) - HelloTrackerAdapter → HelloResolved / HelloResolvedPart2 (payload trägt HelloOutcome: completed|skipped|timeout|not_configured|wizard_not_started) Adapter-Pattern: - internal sealed class : IDisposable - Ctor: Collector + ISignalIngressSink + IClock + optional part2Mode - Subscribe auf Collector-Event; dedup-Flag (fire-once) - TriggerFromTest() internal hook für Tests (umgeht Event-Plumbing) - Dispose() unsubscribed - Keine Modifikation der Collector-Files (§2.11 transitional-SKIP bleibt) PII-Guard in AAD-Adapter: nur userDomain im Payload, nicht full email. New tests (+21, 95 total V2.Core.Tests): - Trigger → Post mit korrektem Kind/Evidence/Payload - part2Mode → Part-2-Signal-Kinds - Duplicate-Trigger → Dedup - Null-Args → ArgumentNullException - HelloOutcome-Varianten (Theory, 5 values) - AAD PII-Guard (full email NICHT in payload) Pattern-Erkenntnisse: - Collectors sind meist internal — Adapter sind auch internal (InternalsVisibleTo Agent.V2 + V2.Core.Tests deckt Usage) - Evidence.Derived braucht mind. einen DerivationInput — Adapter setzen sinnvolle Detection-Source-Keys - Part-1/Part-2 via bool-Ctor-Param (einfacher als 2 Klassen) Testsuite: 1195 → 1216. V2-isolation clean.

Wird in M4.4 Orchestrator direkt an TelemetryTransport als Kind=Event gebridged, nicht als SignalAdapter. Event 509 (WhiteGlove Start) war in Legacy Scoring-Factor (+15); per M3-Erkenntnis wurde das Weight in V2 entfernt → keine Signal-Emission nötig. Tests (+7, 102 total V2.Core.Tests): - Finalizing → EspPhaseChanged mit korrekter EnrollmentPhase.FinalizingSetup - WhiteGloveCompleted → WhiteGloveShellCoreSuccess - EspFailure → EspTerminalFailure mit failureType - Empty failureType → "unknown" fallback - Per-kind independent dedup (3 Events → 3 Posts, Duplicates gefiltert) - All-3-in-one-session flow - Null-args throw Testsuite: 1216 → 1223.

Damit ist die SignalAdapter-Schicht für alle Decision-relevanten Collectors komplett. New: - EspAndHelloTrackerAdapter (Coordinator — Production-Wiring Target in M4.4) - HelloCompleted → HelloResolved / HelloResolvedPart2 - FinalizingSetupPhaseTriggered → EspPhaseChanged (phase=FinalizingSetup) - WhiteGloveCompleted → WhiteGloveShellCoreSuccess - EspFailureDetected → EspTerminalFailure (merged aus ShellCore + Provisioning) - DeviceSetupProvisioningComplete → DeviceSetupProvisioningComplete - Independent per-kind fire-once dedup für alle 5 Signal-Kinds - StallProbeCollectorAdapter - EspFailureDetected → EspTerminalFailure (SourceOrigin=StallProbeCollector unterscheidet von ShellCore/Provisioning/Coordinator — wichtig für Attribution via 4 Scan-Source-Stall-Classifier) Design-Note: - Coordinator vs. Sub-Tracker-Adapter: Sub-Tracker sind in EspAndHelloTracker private; Production nutzt NUR den Coordinator-Adapter. Sub-Tracker-Adapter aus M4.3.1-3 bleiben für Single-Tracker-Wiring-Szenarien und Tests. - Mapping-Logik-Duplikation zwischen Coordinator + Sub-Tracker-Adaptern ist M4.5-Cleanup-Kandidat (SignalAdapterEmitters-Helper oder gemeinsame Mapping-Interfaces). ~50 LoC Duplikation aktuell akzeptiert. Tests (+12, 135 total V2.Core.Tests): - EspAndHelloTracker: Hello/Finalizing/WhiteGlove/EspFailure/DeviceSetupComplete je 1 Test + Part2-Mode + all-5-in-one-session dedup + null-args - StallProbe: Happy-Path, empty-reason-fallback, fire-once, null-args Testsuite: 1244 → 1256. M4.3 komplett — 8 SignalAdapter + 1 StallProbe für alle Decision-relevanten Collectors. ModernDeploymentTracker (nur Events, keine Signals) wird in M4.4 Orchestrator-Wiring direkt an TelemetryTransport gebridged.

Back-pressure observed via TryAdd(0) in Post(); blocking fallback measures duration and notifies IBackPressureObserver, throttled 1x/min/origin. The observer emission path deliberately bypasses the signal channel (would deadlock). Real Events-Bridge wiring lands in M4.4.1 once EventSequenceCounter exists. New abstractions (all in V2.Core.Orchestration, §2.11-conformant): - ISessionTraceOrdinalProvider (thread-safe Interlocked counter, seedable for recovery) - IDecisionStepProcessor (post-Reduce sink; Orchestrator M4.4.5 implements) - IBackPressureObserver (M4.4.1 wires to real Events-Bridge) SignalIngress implements the existing ISignalIngressSink from M4.2 directly so EffectRunner can re-ingest ClassifierVerdictIssued synthetic signals without a separate adapter. +24 tests (1256 -> 1280 green): lifecycle, ordinal monotonicity + recovery, SignalLog-before-Reduce ordering, state progression across reduces, ApplyStep exception resilience, ISignalIngressSink path, back-pressure (fast/slow, throttle same/different origin, clock-rearm, null observer, observer exceptions), concurrent producer ordinal monotonicity.

Three consumers share one sink: - IEventTimelineEmitter impl (EventTimelineEmitter) — expands reducer EmitEventTimelineEntry effect parameters {eventType, reason, ...} into a fully- populated EnrollmentEvent (Severity auto-derived from eventType suffix: _failed->Error, _aborted->Warning, else Info; Source=decision_engine; Phase=Unknown per feedback_phase_strategy; ImmediateUpload=true for terminal events). Timestamp comes from the signal's OccurredAtUtc, not wall clock, keeping replay deterministic. - IBackPressureObserver impl (BackPressureEventObserver) — surfaces signal- ingress back-pressure as agent_trace "ingress_backpressure" events with Severity=Warning, carrying origin + channelCapacity + queueLength + blockDurationMs in Data. Routes via the shared emitter, NOT through the ingress channel (would deadlock, per §2.1a). - (future M4.4.5 wiring) collector onEventCollected callbacks bind Action directly to TelemetryEventEmitter.Emit. Central pieces: - EventSequenceCounter (thread-safe Interlocked-locked counter) with EventSequencePersistence — atomic temp-rename writes to {SessionDir}/Telemetry/event-sequence.json, flush-to-disk per §2.7 L.12. Starts at 1, seeds from file on recovery; persists every Next(). - TelemetryEventEmitter — assigns Sequence + RowKey ({Timestamp:yyyyMMddHHmmssfff}_{Sequence:D10}), serializes via Newtonsoft (PascalCase wire-format, byte-identical to Legacy; backend uses PropertyNameCaseInsensitive ingest), enqueues TelemetryItemDraft Kind=Event to ITelemetryTransport. PartitionKey = {tenantId}_{sessionId}. Minor API change: IEventTimelineEmitter.Emit gains DateTime occurredAtUtc (previously only parameters + state). EffectRunner already has stepOccurredAtUtc in scope — forwarded as one-line change. FakeEventTimelineEmitter test fake updated accordingly; no existing tests reference the old signature. +33 tests (1280 -> 1313 green): sequence monotonicity + recovery-seed + thread-safety, atomic persistence roundtrips + corrupt-file fallback, wire- format field shape (EventType/SessionId/TenantId/Sequence/EventId/RowKey), severity auto-derivation, reason-into-Message + Data propagation, Phase stays Unknown for terminal events, RowKey format, immediate-flush forwarding, back-pressure event shape + clock-driven timestamp.

Skeleton only — the live backend endpoint lands in M5; this milestone only needs the client-side contract testable against HttpMessageHandler fakes. Design: - New class BackendTelemetryUploader in Transport/Telemetry/ (NOT added as a method on the M2-copied Legacy BackendApiClient, which is slated for removal in M4.5 / v11.1+). Lives next to IBackendTelemetryUploader; clean layer, no legacy cross-dependency. - HttpClient injected (not self-constructed). mTLS client-cert wiring stays with the orchestrator-builder in M4.4.5 via HttpClientHandler.ClientCertificates; the uploader itself is cert-agnostic, which makes it trivially testable with a custom handler. - Ctor deps are flat: baseUrl, tenantId, optional hardware/bootstrap/version headers. No AgentConfiguration coupling — orchestrator extracts values. - No retry/back-off here; TelemetryUploadOrchestrator (M4.1) owns that. - Body: JSON array of TelemetryItem via Newtonsoft (PascalCase; Kind as string via existing StringEnumConverter annotation). No gzip — evaluate in M5 once bandwidth profile is known. - HTTP status -> UploadResult mapping: 2xx -> Ok 401 / 403 -> Permanent ("unauthorized: ...") 408 / 429 -> Transient (rate limit / request timeout) other 4xx -> Permanent (client bug; retry pointless) 5xx -> Transient HttpRequestException-> Transient ("network: ...") TaskCanceledException (HttpClient internal timeout, not caller CTS) -> Transient ("timeout: ...") OperationCanceledException with caller-CTS signaled -> rethrow Empty batch short-circuits with Ok (no HTTP call) to avoid wasted round-trips when a concurrent drain emptied the spool mid-upload. - Security headers: X-Tenant-Id (pre-body auth check), hardware headers (X-Device-Manufacturer/Model/SerialNumber for whitelist + Autopilot validation), optional X-Bootstrap-Token (pre-MDM OOBE), X-Agent-Version for kill-switch + diagnostics. New Constants.ApiEndpoints.TelemetryBatch = "/api/telemetry/batch" — shared with M5 backend-side routing. +26 tests (1313 -> 1339 green): URL + header shape, JSON body wire-format (Kind as string, TelemetryItemId/PK/RK/PayloadJson round-trip), empty-batch short-circuit, full HTTP status-code -> UploadResult matrix (2xx/401/403/ 4xx/408/429/5xx), HttpRequestException + timeout mapping, caller cancellation propagation, null-arg rejection.

Plan §4.x M4.4.3 fix. Both are diagnostic signals: they carry hardware inventory / Autopilot profile payload used only by the Inspector and backend analyzers. They do NOT drive stage or hypotheses. Fix is minimal: neutral Taken transitions via a new shared helper RecordDiagnosticObservation — bookkeeping advances, stage/hypotheses untouched, no effects, no DeadEndReason. Full payload stays in the SignalLog for Inspector rendering (Plan §2.7c — Snapshot/Journal are Cache, SignalLog is Master; no reason to duplicate data into DecisionState). Version-gap protection: dispatcher entries are keyed on (Kind, v1). A future v2 payload still dead-ends with unhandled_signal_kind:*:v2 — the L.6 forward-compat contract requires explicit handler upgrades, not silent recording under the old handler. AppInstallCompleted/AppInstallFailed intentionally stay unwired — no decision consumer in v11 scope, and the collector isn't emitting them yet. +11 tests (1339 -> 1350 green): Taken-without-DeadEnd, stage+hypotheses unchanged, bookkeeping advancement, no effects, existing deadlines preserved, v2-schema-version falls through to unhandled.

ClassifierTick armed at SessionStarted (DecisionCore.Shared) Previously the WhiteGlove classifier deadline was armed reactively on the first WG-relevant signal (AttachWhiteGloveClassifierEffects, WhiteGlove.cs). Non-WG sessions and late-WG sessions never got a periodic re-evaluation, which is the M3 re-trigger-lücke. Fix: HandleSessionStartedV1 now schedules the ClassifierTick deadline up-front and emits the matching ScheduleDeadline effect. The existing reactive `hasTick` dedup makes the WG-path arm a no-op once the tick is already present. Classifier-runner anti-loop (snapshot-hash) keeps the tick cheap for non-WG paths until the session reaches a terminal stage and HandleClassifierTickDeadlineFired stops re-arming. Dead-end branch (SessionStarted on active state) is unchanged — no deadline, no effect, state preserved. 2. HelloOutcome now forwards from coordinator (EspAndHelloTrackerAdapter) ReadHelloOutcome() previously returned hardcoded "unknown", so HelloResolved signals always carried that value regardless of what the inner HelloTracker actually observed. The coordinator already exposes a forwarded HelloOutcome property (line 78, since M2) — only the adapter was missing the wiring. One-line fix: `_coordinator.HelloOutcome ?? "unknown"`. 3. ImeLogTracker.OnPatternMatched hook + WhiteGloveSealingPatternDetected emission (ImeLogTracker + ImeLogTrackerAdapter, closing the M4.3.4 tech debt) Added `Action OnPatternMatched` to ImeLogTracker, invoked by HandlePatternMatch after LastMatchedPatternId is set (subscribers can read the ID synchronously). Adapter gains an optional ctor arg `IReadOnlyCollection whiteGloveSealingPatternIds` (default empty, backwards-compatible with pre-M4.4.4 M3 behavior — no emission). When configured and a matching pattern fires, adapter posts WhiteGloveSealingPatternDetected once per session (fire-once). Polling-on- LastMatchedPatternId (alternative A from plan) was rejected; the hook is a real event surface. Orchestrator in M4.4.5 will inject the tenant- configured sealing-pattern-ID list. Bonus: reduced EventSequenceCounterTests thread-safety stress from 6×200 to 4×50 to avoid parallel xUnit test contention on the Windows atomic-rename path (Next() persists to disk per call). Test still catches any counter race via the uniqueness assertion.

Start() verdrahtet die Kern-Pipeline (SignalLog/Journal/Snapshot, TelemetrySpool+Uploader, EventSequence+ Emitter+Timeline+BackPressure, DeadlineScheduler+ClassifierRegistry, EffectRunner, DecisionStepProcessor, SessionTraceOrdinalProvider, SignalIngress) und verbindet Scheduler.Fired → ingress.Post-Bridge. Zirkel EffectRunner-ISignalIngressSink ↔ SignalIngress-Processor via LazyIngressSinkRelay gebrochen. Snapshot-Recovery-Vorstufe bei Start; volle Checksum/Replay-Logik kommt in M4.4.5.f. Shutdown idempotent + reverse-order: Scheduler-Unsubscribe → Scheduler dispose → Ingress.Stop → Drain-Loop cancel → Terminal-Drain → Final- Snapshot → Dispose. IQuarantineSink-Impl setzt Flag (Bewegung erst beim naechsten Start, nicht mid-run). Drain-Loop nutzt Task.Delay (Wall-Clock) statt IClock.Delay, damit VirtualClock-Tests nicht in Tight-Loop laufen. +14 Agent.V2.Core Tests (239 → 253 gruen). Collectors + SignalAdapters folgen in M4.4.5.c, mTLS-HttpClient-Factory in .d, Pattern-Injection in .e, Recovery-Pfade in .f.

Orchestrator ruft Start/Stop/Dispose in korrekter Reihenfolge auf. Die 5 Collectors (HelloTracker, ShellCoreTracker, ProvisioningStatusTracker, StallProbeCollector, ModernDeploymentTracker) haben heavy Production-Deps (Event-Log-Watcher, WMI, Registry) — die Factory-Seam erlaubt Prod-Impl in Program.cs / Tests nutzen Fakes. Exception-Swallow-Wrapper im Orchestrator: ein Emitter-Fail (z.B. Transport disposed) darf den Collector-Thread nicht killen. ModernDeploymentTracker explizit als bridge-only dokumentiert: kein SignalAdapter, nur Event-Bridge — validiert durch dedizierten Test, der prueft dass Events im Transport landen aber SignalLog leer bleibt. Factory optional (default null): Orchestrator ohne Factory laeuft weiter ohne Collectors (backwards-compatible zu M4.4.5.b). +7 Agent.V2.Core Tests (253 → 260 gruen).

Korrektur: die Klasse persistiert den IME-Collector-internal State, nicht DecisionEngine-State: - LogFilePositionTracker: Byte-Offset pro IME-Logfile (ohne das re-parst der Tracker nach Restart von Byte 0 → Event-Spam) - SeenAppIds: Phase-Isolation (Device-Phase-Apps duerfen nicht in AccountSetup-Phase bleeden) - IgnoreList: App-IDs aus abgeschlossenen Phasen, die weiterhin in Logs auftauchen koennen - Packages (AppPackageStateList): vollstaendiger Install-Progress, DO-Telemetry, ErrorPatterns, AppType, AttemptNumber — essentiell fuer App-Download-Monitor, Install-Monitor, App-Summaries - Phase-Tracking (CurrentPhaseOrder, LastEspPhaseDetected, etc.) SignalLog-Replay deckt das NICHT ab — der SignalLog persistiert DecisionSignals (SessionStarted, EspPhaseChanged, HelloResolved, …), nicht per-App-Install-Progress oder Log-File-Positions. Restore: - ImeTrackerStatePersistence.cs wieder aus git history - ImeLogTracker.cs: _statePersistence-Feld + Ctor-Init + LoadState/SaveState/DeleteState-Bodies aus 8ca845c^ restored (nur die beiden dead using-Imports auf Flows/Completion bleiben entfernt, da deren Namespaces tatsaechlich geloescht sind) Build + Tests gruen (286/287, known pre-existing Flake bleibt fuer M4.5.c).

Tatsächlich persistiert sie collector-internal IME-Tracker-State: LogFilePositionTracker-Byte-Offsets, `SeenAppIds` (Phase-Isolation), komplette `AppPackageStateList` mit DO-Metriken + Install-Progress + AppType + AttemptNumber + DetectionResult + ErrorPatterns. Das ist peripheral capability per `feedback_v2_kernel_only_refactor` (App-Download-Monitor, Install-Monitor, Per-App-Summaries — Produkt-Kernfeatures), NICHT DecisionEngine-State. SignalLog-Replay deckt das NICHT ab. Ohne die Persistenz: nach Restart Byte-0-Re-Parse aller IME-Logs, Event-Duplikate, Phase-Bleed, verlorener In-Flight-Download-Progress. Ich hatte die Regel in meinem eigenen Plan-Doc zitiert und trotzdem angewandt — weil Kategorisierung nach Pfad ("Enrollment" im Ordner) statt nach Funktion (was persistiert die Datei?) erfolgte, Plan-Doc + Explore-Agent-Output ohne Kontrolle übernommen wurden, und weil `…` am Ende der Feedback-Liste nicht als "non-exhaustive" interpretiert wurde. +**Rule:** Vor jedem `rm`/`git rm` eines Files in V2.Core (insbesondere unter `Monitoring/Enrollment/`, `Monitoring/Transport/`, `Monitoring/Runtime/`): `Read` die Datei, frag "DecisionEngine-Concern (Stage, Hypothesis, Deadlines, Facts) oder Collector-Concern (Byte-Offsets, App-Progress, WMI-Cache, Phase-Isolation)?". Collector-Concern bleibt — egal wo die Datei im Pfad liegt. Zusatz-Check: "Was bricht nach Restart ohne diese Datei?" — wenn Re-Parse/Verlust-Progress/Phase-Bleed → Peripheral, bleibt. Plan-Doc + Explore-Agent sind Startpunkt, nicht Autorität. +**Severity:** PRODUCTION — hätte App-Tracking komplett zerschossen nach Agent-Restart. Gefangen durch User-Review vor Deploy. +**Reference:** [feedback_peripheral_classify_by_function.md](C:/Users/OliverKieselbach/.claude/projects/c--Code-GitHubRepos-Autopilot-Monitor/memory/feedback_peripheral_classify_by_function.md) + ### Timeline sequence must NEVER regress in the curated UI view (2026-04-04) **What went wrong:** `groupEventsByPhase` was called without `preventPhaseRegression: true` for normal sessions and WhiteGlove pre-provisioning. A mid-enrollment reboot emits a new `agent_started` (Phase 0 = "Start"), which regressed the active phase back to Start, dumping post-reboot events (seq 173+) into the Start section — breaking the sequential appearance. **Rule:** ALL `groupEventsByPhase` calls MUST use `{ preventPhaseRegression: true }`. The curated timeline sequence must appear continuous within each phase section. Reboots and agent restarts must NOT create phase regression — events stay in whatever phase was active before the reboot.

All of this is driven off a single typed kernel event so nothing leaks back into the DecisionEngine. Terminal-stage detection (kernel hook) - DecisionCore/State/SessionStageExtensions.IsTerminal() + IsPauseBeforePart2() — Completed, Failed, WhiteGloveSealed, WhiteGloveCompletedPart2 are terminal; WhiteGloveSealed is the "pause before Part 2" special case (session resumes on reboot, cleanup MUST be suppressed). - DecisionStepProcessor ctor gains Action? onTerminalStageReached; fires at most once per processor lifetime, swallows handler exceptions, suppressed when initial state was already terminal (crash-recovery race). - EnrollmentOrchestrator.OnDecisionTerminalStage translates the hook into the public Terminated event with Reason=DecisionTerminalStage + Outcome mapped from stage (Completed/Part2/Sealed→Succeeded, Failed→Failed, else TimedOut). MaxLifetime watchdog is cancelled on the real terminal so the two paths can't race each other. Peripheral termination (V2.Core/Termination/*) - FinalStatus DTO — wire-format mirror of SummaryDialog's Models/FinalStatus (same JSON property names). Lives in V2.Core because the dialog is a separate net48 WPF exe we can't ProjectReference. - FinalStatusBuilder — pure function: DecisionState + AppPackageStateList + TerminatedArgs + agent start time → FinalStatus. Maps outcome string ("succeeded" | "failed" | "timed_out" | "whiteglove_part1" | "whiteglove_part2"), derives signalsSeen from DecisionState facts, counts apps by AppTargeted phase (Device/User), tallies device vs user errors. - SummaryDialogLauncher — writes final-status.json, copies dialog exe + deps + status file to a per-launch temp dir (%TEMP%\AutopilotMonitor-Summary\), composes the Legacy-compatible CLI (--status-file, --timeout, --cleanup, optional --branding-url), invokes UserSessionProcessLauncher.LaunchInUserSession with the configured retry window. Fire-and-forget, swallows all errors. - EnrollmentTerminationHandler — the Terminated-event handler that sequences: build FinalStatus → write JSON + launch dialog → upload diagnostics (respects DiagnosticsUploadMode: Off/Always/OnFailure) → write enrollment-complete.marker (suppressed on WhiteGloveSealed) → run CleanupService.ExecuteSelfDestruct (suppressed on WhiteGloveSealed OR when SelfDestructOnComplete=false) → signal shutdown MRE. Idempotent; each step is best-effort and logs rather than throws — nothing is allowed to prevent agent shutdown. DefaultComponentFactory - Stores the ImeLogHost it creates and exposes its PackageStates to the termination pipeline (factory.ImePackageStates) so FinalStatusBuilder has the live package list without breaking host encapsulation. Program.cs wiring - Instantiates DiagnosticsPackageService, EnrollmentTerminationHandler, and ServerActionDispatcher with all callbacks live: • rotate_config → RemoteConfigService.FetchConfigAsync() • request_diagnostics → DiagnosticsPackageService.CreateAndUploadAsync() • terminate_session → EnrollmentTerminationHandler.Handle() synthesising a DecisionTerminalStage/Failed termination - Terminated event routed to the handler; the handler signals the shutdown MRE so the main thread cleanly calls orchestrator.Stop(). - ServerActionDispatcher is alive but has no ingest-response consumer yet — V2 batch endpoint is M5 scope, we plumb the API contract here so M5 can drop in the response parser.

StartupEnvironmentProbes (V2.Core/Runtime/) - New helper that replicates the Legacy MonitoringService startup diagnostic trio: device_location / timezone_auto_set / ntp_time_check. - Sequential RunAsync(config, logger, emitter): geo lookup → (optional) tzutil auto-set → NTP offset check. Each step is best-effort and feeds through the orchestrator's TelemetryEventEmitter. - Geo probe respects EnableGeoLocation; timezone probe respects EnableTimezoneAutoSet AND requires an IANA tz from geo. NTP probe always runs (diagnostic-only; Warning on offset >60s or failure). - Program.cs wires this via Task.Run right after orchestrator.Start so a slow network never delays the critical path. EmergencyReporter + DistressReporter (live in Program.cs) - Previously instantiated nowhere — now built once at startup with the shared hardware info. RemoteConfigService ctor takes both so config-fetch failures flow to the right channel (auth → distress, network → emergency). - Initial AuthCertificateMissing distress fires when UseClientCertAuth=true but BackendApiClient.ClientCertificate is null — surfaces pre-MDM- enrollment dead-ends via the cert-less channel (Legacy parity). - BackendTelemetryUploader uses the same hardware info (dedup'd the second HardwareInfo.GetHardwareInfo call that was duplicated since M4.5.b). DeliveryOptimizationHost (DefaultComponentFactory nested) - New ICollectorHost wrapping DeliveryOptimizationCollector with: • getPackageStates → ImeLogHost.PackageStates (existing accessor) • onDoTelemetryReceived → ImeLogHost.Tracker.OnDoTelemetryReceived pass- through (new internal accessor; keeps encapsulation) • OnAppStateChanged chained into ImeLogTracker so WakeUp() fires when any app enters Downloading or Installing — before any fire we preserve the existing handler (the adapter's signal-ingest path must keep running unchanged). - Gated by CollectorConfiguration.EnableDeliveryOptimizationCollector. Tests (+8 in V2.Core.Tests → 353 → 361) - StartupEnvironmentProbesTests: event-shape for all three probes + geo success/failure/null attempt, timezone success/failure severity, NTP small/large offset + failure-with-detail. All 4 suites green: 88 DecisionCore + 361 V2.Core + 507 Agent.Core + 557 Functions = 1513 tests green. Note: the "RegistryWatcher standalone admin-action-detector" from the original M4.6 gap list was a Subagent fabrication — verified no such usage exists in either Legacy or V2 (the class is only consumed transitively inside AadJoinWatcher + ProvisioningStatusTracker, both already wired via DefaultComponentFactory since M4.5.b). Removed from the M4.6.γ scope. Remaining: M4.6.δ (--run-gather-rules + --run-ime-matching modes, AnalyzerManager + 3 Analyzers).

After this commit the V2 agent has full feature parity with the Legacy agent around every capability NOT inside the DecisionEngine itself. Diagnostic CLI modes (Program.*.cs partials) - --run-gather-rules: ported 1:1 from Legacy. Resolves TenantId via V2 TenantIdResolver, creates a fresh ephemeral SessionId, registers it, fetches remote config, runs GatherRuleExecutor against all Trigger=startup rules (120s cap), uploads the collected events in-memory via BackendApiClient.IngestEventsAsync. Never touches the live agent's spool. - --run-ime-matching [--patterns ]: ported 1:1 from Legacy. Single-file or directory scan through the same IME log-file patterns the live tracker watches, loads patterns from GitHub (fallback: cached remote-config.json), compiles regexes with {GUID} substitution + 1s timeout, scans + writes ime_pattern_matching.log with per-pattern counts. - Both modes fork early in Main before orchestrator startup — no side effects on the Scheduled Task, no process conflict with the live agent. AgentAnalyzerManager (V2.Core/Runtime/) - Ported from Legacy AnalyzerManager. Reads AnalyzerConfiguration from AgentConfigResponse.Analyzers directly (no RemoteConfigService indirection — the cache is already resolved at call site). - Initialize() registers LocalAdminAnalyzer / SoftwareInventoryAnalyzer / IntegrityBypassAnalyzer gated by Enable* flags; idempotent across repeated calls. - RunStartup() fires on a background task, swallows per-analyzer exceptions. Called from Program.cs right after orchestrator.Start so analyzers emit through the live TelemetryEventEmitter. - RunShutdown(int? whiteGlovePart) runs synchronously before the diagnostics upload, routing SoftwareInventoryAnalyzer to its overload that distinguishes WhiteGlove part 1 baseline from part 2 delta. EnrollmentTerminationHandler integration - New optional `analyzerManager` ctor param. RunShutdownAnalyzers runs FIRST in the termination sequence (before FinalStatus + diagnostics upload) so the analyzers' delta events make it into the final diagnostics ZIP. Passes whiteGlovePart=1 on WhiteGloveSealed terminal. GatherRuleExecutorHost (DefaultComponentFactory nested) - Runtime gather-rules execution via a new ICollectorHost that wraps GatherRuleExecutor. Only registered when remoteConfig.GatherRules has entries. Picks up ImeLogPathOverride for file-collector paths. - Legacy parity: gather rules run as part of the active enrollment session alongside the collector hosts, not only via the standalone --run- gather-rules diagnostic mode. Program.cs mode fork (Main) - --install / --run-gather-rules / --run-ime-matching handled in order after --help / --version, before multi-instance guard and self-update (those only apply to the normal monitoring mode). Tests (+8 in V2.Core.Tests → 369) - AgentAnalyzerManagerTests: toggle-matrix, null-config default behaviour, idempotent Initialize, argument-null guards, fake-analyzer injection for RunShutdown success/exception/empty-list paths. The three real analyzers already have their own parity-tested implementations in V2.Core shared with Legacy. All 4 suites green: 88 DecisionCore + 369 V2.Core + 507 Agent.Core + 557 Functions = 1521 tests green. M4.6 is now complete. The V2 agent matches Legacy feature parity for: install mode, self-update, multi-instance guard, clean-exit marker, previous-exit classification, enrollment-complete ghost-restart detection, session-age emergency break, AgentMaxLifetime watchdog, BootstrapConfigCleanup, terminal-stage detection with typed Terminated event, FinalStatus.json + SummaryDialog launch via UserSessionProcessLauncher, CleanupService self- destruct (with WhiteGlove-part-1 pause), DiagnosticsPackageService upload, ServerActionDispatcher (terminate_session / request_diagnostics / rotate_ config callbacks ready for M5 response-path plumbing), Geo/NTP/Timezone probes, Emergency + Distress reporters, DeliveryOptimizationCollector, 3 analyzers, --run-gather-rules + --run-ime-matching diagnostic modes.

Without this the V2 agent had no way to be remotely stopped or quarantined — it could only be self-destructed by its own decision engine. UploadResult extended - New optional fields on success: DeviceBlocked, UnblockAt, DeviceKillSignal, AdminAction, Actions. Factory OkWithSignals(...) for success-with-control. - Legacy-parity: same semantic as IngestEventsResponse's quarantine / kill / admin surface, just riding on the new /api/telemetry/batch response body. BackendTelemetryUploader.TryReadControlSignalsAsync - Parses the 2xx response body as JSON (defensive — empty body or malformed JSON degrades cleanly to plain Ok). Accepts both camelCase and PascalCase field names so an M5 backend can choose either without breaking V2 agents in the wild. - Recognises deviceBlocked (bool) + unblockAt (ISO-8601 UTC) + deviceKillSignal (bool) + adminAction (string) + actions (ServerAction[]). TelemetryUploadOrchestrator - New public event ServerResponseReceived fires on successful uploads that carry any control signal. Handlers run after the cursor has moved, so a handler exception does not abort or re-run the batch. - New public IsPaused property — DeviceBlocked sets an internal _pausedUntilUtc; subsequent DrainAllAsync calls short-circuit with a "device blocked" LastErrorReason until UnblockAt elapses (or indefinitely when UnblockAt is null). UnblockAt=null maps to DateTime.MaxValue so the comparison stays deterministic without a null branch per tick. EnrollmentOrchestrator.Transport property - Exposes the live TelemetryUploadOrchestrator so Program.cs can subscribe to ServerResponseReceived without leaking transport internals through public orchestrator API. Program.cs WireTelemetryServerResponse - Routes ServerResponseReceived through the existing ServerActionDispatcher: • DeviceKillSignal → synthesises terminate_session with forceSelfDestruct= true + gracePeriodSeconds=0 (kill overrides local SelfDestructOnComplete config — Legacy parity, the operator's decision wins) • AdminAction → synthesises soft terminate_session respecting local config • Actions[] → dispatched directly • DeviceBlocked → logged (the transport already paused itself) - onTerminateRequested extended: reads params["forceSelfDestruct"] and flips agentConfig.SelfDestructOnComplete at runtime when set, so the cleanup service actually runs. Tests (+15 in V2.Core.Tests → 384) - BackendTelemetryUploaderControlSignalsTests: empty body, malformed JSON, DeviceBlocked + UnblockAt, PascalCase accepted, DeviceKillSignal, AdminAction, Actions array round-trip, non-2xx does not parse signals, body with only unknown fields. - TelemetryUploadOrchestratorServerResponseTests: plain Ok is silent, kill-signal raises event once, admin-action forwards field, actions forward list, DeviceBlocked pauses → unblock lifts pause → next drain uploads the queued item, handler exceptions do not break cursor. All 4 suites green: 88 DecisionCore + 384 V2.Core + 507 Agent.Core + 557 Functions = 1536 tests green. With this commit M4.6 closes all known Legacy-vs-V2 peripheral-parity gaps: agent_kill (DeviceKillSignal → synthesized terminate_session), agent_blocked (DeviceBlocked → paused drain), portal Mark-Failed/Mark-Succeeded (AdminAction → synthesized terminate_session), plus the generic server-queued Actions[].

The V2 uploader only benefitted from response-side gzip (AutomaticDecompression on the mTLS handler) and shipped plain-JSON outbound. Compress the serialised JSON-array batch with GZipStream, swap StringContent for ByteArrayContent, advertise Content-Encoding: gzip. Wire format stays JSON-array — M5 backend contract is unchanged, only the transport is compressed. RecordingHttpMessageHandler transparently gunzips captured bodies so existing parse assertions keep working, and now exposes RawBody for the new gzip magic-byte / size test.

Adds the two primary Decision-Engine tables projected from the agent-side SignalLog and Journal so the Inspector + Reducer-Verifier can replay sessions. - Constants.TableNames: Signals, DecisionTransitions (+ All[] init). - Shared DTOs SignalRecord / DecisionTransitionRecord carry a flat projection plus the agent-serialised PayloadJson for full fidelity. DecisionTransitionRecord eagerly carries index discriminators (IsTerminal, ClassifierVerdictId, ClassifierHypothesisLevel) so the later index fan-out can read them straight off the primary row. - ISignalRepository / IDecisionTransitionRepository: lean interfaces (StoreBatchAsync only — queries land with the read endpoints in M5.c). - TableSignalRepository / TableDecisionTransitionRepository: idempotent UpsertReplace via entity-group-transactions, grouped per (tenant, session), chunked at the 100-op Azure limit. PayloadJson goes through TableStorageChunking so the 32K-char property ceiling can't bite on large Evidence + Payload blobs. - Registered in DataAccessServiceExtensions alongside the existing 13 Table repositories — Cosmos swap remains a single-file change. - 11 pure mapping tests cover key builders (PK tenant_session, RK D19(ordinal) / D10(stepIndex), lex-ordering invariant), full entity projection, chunked PayloadJson handling, dead-end paths, and null-payload tolerance. Index tables (SessionsByTerminal, SessionsByStage, DeadEndsByReason, ClassifierVerdictsByIdLevel, SignalsByKind) land with the queue-driven fan-out in M5.b; the primary schemas are stable.

Malformed PayloadJson on a single item returns null; one poisonous item can't poison the batch. Projects index discriminators (IsTerminal, ClassifierVerdictId, ClassifierHypothesisLevel) off the DecisionTransition payload so the later queue-driven index fan-out reads them straight off the primary row. - EndpointAccessPolicyCatalog: POST agent/telemetry registered under DeviceOrBootstrapAuth (same policy as agent/ingest). Without this the fail-closed catalog rejects the route with 403. Scope boundary — Events get stored via StoreEventsBatchAsync only; the rule engine, app-install aggregation, SignalR notification, and vulnerability correlation remain on the legacy /api/agent/ingest path. Sharing that pipeline is tracked as M5.b.2 (extract EventIngestProcessor so both functions run the same downstream steps) — M7 rollout gates on completing it. Documented inline in PersistItemsAsync. 28 new tests: defensive null-handling per kind, typed-column extraction for Signal (with envelope fallback for missing SessionTraceOrdinal), DecisionTransition dead-end + classifier-verdict nesting, IsTerminal authoritative-list guard (Completed / Failed / WhiteGloveSealed / WhiteGloveCompletedPart2 — mirrors DecisionCore SessionStageExtensions), PartitionKey parser including malformed-shape rejection. The EndpointPolicyCatalogCompletenessTests guard the route registration.

Deliberate copy-duplication, not a shared refactor: - Legacy /api/agent/ingest is production-hot — it serves live traffic from every deployed V1 agent and is NOT touched by this commit. Zero regression risk on the existing path. - EventIngestProcessor is a near-verbatim copy of the legacy pipeline's tail (~1000 LoC). Duplication is accepted because legacy /api/agent/ingest is scheduled for decommission post-v11 GA (see tasks/todo.md → Follow-Ups → Legacy-Agent-Ausmusterung). Until then: bugs fixed in legacy must be ported here manually. Copied pipeline steps (all 1:1 with legacy ProcessIngestAsync lines 150-566): StampServerFields → SanitizeEventTimestamps → StoreEventsBatchAsync → Index updates fire-and-forget → IME agent version history → ClassifyEvents → App install summaries → Geo-location update → UpdateSessionStatusAsync (all 7 status branches) → IncrementSessionEventCountAsync → Rule engine analysis fire-and-forget + SignalR + stats → Vulnerability correlation with WhiteGlove Part-2 merge → IncrementPlatformStatAsync TotalEvents + SuccessfulEnrollments → RecordGatherRuleStatsAsync → Diagnostics blob update → GetSession for updatedSession → Session age 4h warning → WhiteGlove IsPreProvisioned error log → SendWebhookNotificationsAsync (all 3 alert paths) → SLA breach evaluation → Admin override detection → ServerAction fetch-and-clear with TrackEvent telemetry → BuildSignalRMessages. Shared (not duplicated, to avoid drift in pure helpers): IngestEventsFunction.StampServerFields, SanitizeEventTimestamps, RecalculateAppDurations (all internal static, state-less, stable). The internal DTOs EventClassification + AppInstallAggregationState are also reused — they carry no behaviour, only fields. IngestTelemetryFunction wiring: - Return type HttpResponseData → IngestEventsOutput so the V2 endpoint can emit SignalR messages for the real-time UI push (matches legacy binding). - PersistItemsAsync partitions the batch: Events go through the processor (full pipeline + AdminAction + pending ServerActions + SignalR); Signal + Transition batches skip the processor and read control signals directly via a lean ReadControlSignalsAsync helper on ISessionRepository — no point firing the full pipeline for a batch that carries no events. - EventIngestProcessor registered in Program.cs DI. Known gap (explicitly NOT in this commit): the V2 endpoint lacks a payload size guard (legacy reads MaxNdjsonPayloadSizeMB from tenant config in ParseNdjsonRequest). Different payload shape (JSON array vs NDJSON), deferred to a dedicated follow-up. All 596 backend tests green (unchanged count — copy path has no new tests yet; the V2 endpoint's behaviour is validated by the legacy test coverage through the shared-helper surface + the TelemetryPayloadParser tests from M5.b.1). Integration coverage lands with M7 test-VM smoke.

All 596 backend tests green. No changes to behaviour or to legacy /api/agent/ingest.

Closes the documented gap from M5.b — the V2 endpoint previously accepted unbounded bodies while legacy /api/agent/ingest has capped NDJSON payloads since day one. - Reuse existing TenantConfiguration.MaxNdjsonPayloadSizeMB (table-only, admin-set, default 5 MB). The property name is historical; scope is shape-agnostic — both NDJSON and JSON-array paths now share the knob. Doc comment updated to reflect that. No new config surface. - New internal static helper IngestTelemetryFunction.ReadBodyWithSizeCapAsync reads the already-gzip-decompressed request stream with a strict byte cap. Short-circuits + returns (exceeded=true, body="") the instant the cap would be exceeded, so a malicious sender can't force a 100 MB allocation. Semantics match legacy NdjsonParser: strict greater-than, equal-to accepted. - Cap exceeded → HTTP 413 Payload Too Large with IngestEventsResponse body (Success=false, Message describes limit). Agent's UploadResult parser classifies 413 as Permanent (not retried), which is correct — the same batch will fail again. The agent handles this by dropping the batch from the spool after the permanent-failure log. 4 new tests: under cap, exactly at cap, over cap (asserting the stream is not fully drained — memory bound), empty stream. 600/600 backend tests green.

The first three were already wired through adminConfig; the last one was declared on the DTO but never populated from storage — V2 agents always received an empty list, effectively leaving the sealing-pattern emission path dead. Adds the missing plumbing: - AdminConfiguration.WhiteGloveSealingPatternIdsJson (string, JSON-serialised List) + GetWhiteGloveSealingPatternIds() helper. Defaults to empty for null/whitespace/invalid JSON so the feature stays off by default (M3-compatible, no regression on tenants that haven't opted in). Global-only, no per-tenant override (plan §M5 M4.4.5.e decision). - TableConfigRepository Store + Map entries for the new column (feedback_table_storage_serialization — new model properties MUST round-trip through the table mapping or the field silently drops on save/load). - GetAgentConfigFunction populates WhiteGloveSealingPatternIds from adminConfig.GetWhiteGloveSealingPatternIds(). ConfigVersion bumped 25 → 26 as a semantic-change marker. 5 new tests mirror the HarmlessEventIds pattern (null / whitespace / invalid JSON / valid round-trip / explicit empty array). 605/605 backend tests green. Agent-side (M4.4.4 / M4.4.5.e): the V2 agent's OnPatternMatched hook already reads WhiteGloveSealingPatternIds from the cached config and re-emits matching IME pattern hits as WhiteGloveSealingPatternDetected DecisionSignals. With this commit the data path is end-to-end.

Returns the SignalLog for a session — ordered by SessionSignalOrdinal, bounded by a caller-supplied maxResults with a hard 5000 cap. - ISignalRepository.QueryBySessionAsync added alongside the existing StoreBatchAsync. Uses Azure Tables filter on PartitionKey = {tenant}_{session}; the D19(ordinal) RowKey padding means lex order already matches numeric order, so the explicit sort on return is a redundancy guard — cheap invariant check, not a real cost. - TableSignalRepository.FromEntity — reverse mapping (entity → SignalRecord) that mirrors ToEntity, including TableStorageChunking.ReassembleProperty for oversized PayloadJson. Round-trip tested end-to-end. - GetSessionSignalsFunction.Run — follows the same shape as GetSessionEventsFunction: RequestContext.TargetTenantId resolved by PolicyEnforcementMiddleware, Global-Admin cross-tenant fallback via SessionsIndex when the effective-tenant query comes up empty. - ParseMaxResults extracted as a pure helper taking the raw query string (not HttpRequestData) so it's unit-testable without mocking the abstract Worker HttpRequestData class. - Endpoint registered in EndpointAccessPolicyCatalog under MemberRead + TenantScoping.QueryParam (same policy as sessions/{id}/events). Without this the fail-closed catalog would reject the route with 403 — verified by the EndpointPolicyCatalogCompletenessTests. 9 new tests (614/614 backend green): ParseMaxResults defaults / garbage / in-range / cap / negative / null query string (6), plus FromEntity round-trip (simple payload + oversized-chunked payload).

Server-side projection from the persisted DecisionTransitions journal into a renderable DAG so the UI consumes one structured shape instead of rebuilding the graph on every page open, and so "what counts as terminal" stays authoritative next to the backend copy of that list. - Shared DTO DecisionGraphProjection (Nodes + Edges + ReducerVersion). Nodes are de-duplicated stages with IsTerminal + a coarse TerminalOutcome label ("Succeeded" / "Failed" / "PausedForPart2"). Edges are one per transition, preserving dead-ends (Taken=false) for the UI to render in a distinct style. VisitCount counts *taken* transitions only — dead-ends don't advance the heat-map. - IDecisionTransitionRepository.QueryBySessionAsync added alongside StoreBatchAsync. Mirror of the M5.c.1 Signals pattern: PartitionKey filter, explicit StepIndex sort as a redundancy guard (the D10 RowKey padding already matches numeric order). - TableDecisionTransitionRepository.FromEntity — reverse mapping (entity → record) including TableStorageChunking.ReassembleProperty for oversized PayloadJson. Round-trip tested end-to-end. - DecisionGraphBuilder.Build — pure projection function, no IO, no service deps. Unit-testable against canned transition lists; the test suite covers empty input, node de-duplication, terminal classification for all 4 stages, dead-end preservation, StepIndex ordering under shuffled input, and VisitCount semantics. - GetSessionDecisionGraphFunction — same shape as GetSessionSignalsFunction (RequestContext resolution, Global-Admin cross-tenant fallback), plus a truncation flag when the 5000-step cap is hit. - Endpoint registered in EndpointAccessPolicyCatalog under MemberRead + TenantScoping.QueryParam (sibling of sessions/{id}/events). Scope boundary — the plan calls for terminal-node decoration with the richer TerminationReason + TerminationOutcome from the M4.6.β enrollment_terminated event. That data lives in the Events table, not in the transition journal; joining it here would expand scope into cross-table reads. The current projection exposes the coarse TerminalOutcome label (derived from the transition's ToStage) which is enough for the M6 Inspector's initial DAG render. Richer decoration is a dedicated follow-up. Three sources of truth now carry the terminal-stage list: agent-side DecisionCore.SessionStageExtensions.IsTerminal, backend-ingest TelemetryPayloadParser.IsTerminalStage, and now DecisionGraphBuilder's copy. Adding a new terminal stage = three places to update; flagged in the builder's docstring so it doesn't get missed. 627/627 backend tests green (+13: 11 builder + 2 transition round-trip).

Admin-only (not tenant-exposed) structural health check over a session's persisted SignalLog + DecisionTransitions journal. Closes the M5 read-endpoint trio. - Shared DTO ReducerVerificationReport + VerificationIssue: counts, ordinal / step-index contiguity, ReducerVersion drift, orphaned-reference count, human-readable issue stream for the Inspector's verification panel. - ReducerVerifier.Verify — pure function, zero IO. Five detectors: empty-session (Info), signal ordinal gaps (Warning, capped at 20 issues + overflow summary to keep reports bounded), step-index gaps (Warning, same cap), orphaned transitions whose SignalOrdinalRef falls outside the loaded signal set (Warning, capped), and ReducerVersion drift (Info — known condition per plan §2.10, not an error). - GetSessionReducerVerificationFunction — reads signals + transitions for the session, loads the live DecisionEngine.ReducerVersion, runs the verifier, returns the report. Global-Admin cross-tenant fallback via SessionsIndex when the effective tenant has no data. Truncation flag when either the 5000-signal or 5000-transition cap is hit. - Endpoint gated by EndpointPolicy.GlobalAdminOnly — the plan explicitly scopes this to adminMode/ops access. The fail-closed catalog policy completeness test enforces the registration. Scope boundary explicitly documented on the function: full engine replay (DecisionEngine.Reduce over reconstructed DecisionSignals with per-step diff) is NOT implemented in this commit. It would require polymorphic deserialisation of SignalRecord.PayloadJson back into DecisionSignal with its Evidence abstract type, which is a non-trivial refactor. The structural checks land today catch the realistic release-gate failure modes (corruption, drift, orphan refs) and give ops a usable tool. Full replay is a dedicated follow-up once the Evidence deserialisation contract is pinned down. 9 new tests cover all five detectors plus happy path, shuffled input, and the issue-cap overflow message. 636/636 backend green.

Adds: - 5 sealed DTO records in Shared/Models/IndexRecords.cs carrying only discriminator columns + back-refs (StepIndex / SessionSignalOrdinal) to the primary row — no PayloadJson chunking needed. - IIndexTableRepository with 5 Store*Async methods (single-interface shape keeps boilerplate low; Cosmos swap remains trivial since each Store* is independent). - IndexRowKeys pure static helper for all PK/RK formats per Plan §2.8: D6 StepIndex suffix, D10 SessionSignalOrdinal suffix, D19 Ticks padding for SessionsByStage (matches lex ordering to numeric time). Defensive Sanitize() for forbidden PK/RK chars (/\#?). - TableIndexRepository with a generic group-by-PK + 100-op-chunk UpsertReplace write path mirroring TableSignalRepository. - DI wiring in DataAccessServiceExtensions. Scope: write-only. Query methods deferred until MCP/Web concretely need them. No queue producer / reconcile handler yet — that lands in M5.d.2+. Tests (+25 in Functions): 15 PK/RK format assertions in IndexRowKeysTests + 10 entity-projection round-trips (incl. null-tolerance) in TableIndexRepositoryMappingTests. Full Functions suite: 661 green (prev 636 + 25 new). Full solution build green.

Components: - Constants.QueueNames.TelemetryIndexReconcile (azure-queue-name-safe, all lowercase + hyphens). - IndexReconcileEnvelope (Shared DTO, flat shape with nullable fields per SourceKind="Signal"/"DecisionTransition"). Avoids polymorphic Newtonsoft deserialization — see M5.c.3 finding. - IndexReconcileEnvelopeFactory pure static helper (FromSignal / FromDecisionTransition / BuildBatch) — state-less projection. - IIndexReconcileProducer (Shared interface) contract: no-op when the feature flag is off; never rethrows underlying-queue failures. - AzureQueueIndexReconcileProducer (Functions) — Base64-encoded JSON messages, lazy CreateIfNotExistsAsync guarded by Interlocked flag, Managed-Identity-or-connection-string construction mirroring BlobStorageService / TableStorageService. - IngestTelemetryFunction ctor gains IIndexReconcileProducer; after primary Signals + DecisionTransitions commit it builds envelopes and enqueues them. Event path is untouched (events don't feed the index tables per §2.8). - Program.cs registers the producer as a singleton. Feature gate (AdminConfiguration.EnableIndexDualWrite, default false): - New bool field in AdminConfiguration. - TableConfigRepository Store + Map extension (per feedback_table_storage_serialization). - Producer checks config each call via AdminConfigurationService's 5-min memory cache. Flag off → primary behaviour is bit-exact. Fault tolerance: queue-side exceptions (network, throttling, missing queue before first CreateIfNotExists) are logged per envelope and swallowed. The primary row is the source of truth; the 2h reconcile timer (M5.d.4) is the safety-net recovery path. Tests (+11 in Functions): - 5 IndexReconcileEnvelopeFactoryTests: Signal/DecisionTransition projection, dead-end preservation, batch ordering, null/empty. - 3 IndexReconcileEnvelopeSerializationTests: Newtonsoft round-trip (Signal, full DecisionTransition, minimal-envelope tolerance). - 3 AdminConfigurationEnableIndexDualWriteTests: default-false on new config + CreateDefault, persists when set. Deferred to later sub-milestones: - M5.d.3: queue-triggered consumer that maps envelopes to 0–3 index rows using M5.d.1 TableIndexRepository. - M5.d.4: 2h reconcile timer + release-gate dual-write verification tests, then flip EnableIndexDualWrite=true in prod admin config. Full Functions suite: 672 green (prev 661 + 11 new). Full solution build green.

Closes the producer→consumer loop; once the EnableIndexDualWrite flag is flipped, primary commits drive eventual-consistent index upserts asynchronously. Components: - Microsoft.Azure.Functions.Worker.Extensions.Storage.Queues 5.5.4 package for the isolated-worker QueueTrigger binding. - IndexReconcileHandler (plain class — not interface-abstracted per Plan §M5.d design: DAL abstraction lives at IIndexTableRepository, not here). Routing: Signal → SignalsByKind (always, 1 row). DecisionTransition: IsTerminal=true → SessionsByTerminal Taken=true → SessionsByStage Taken=false + reason → DeadEndsByReason ClassifierVerdictId!=null → ClassifierVerdictsByIdLevel Up to 3 rows per DecisionTransition envelope (a Taken+terminal+ classifier transition fans to SessionsByTerminal + SessionsByStage + ClassifierVerdictsByIdLevel). - IndexReconcileFunction thin QueueTrigger wrapper (Connection = AzureTableStorageConnectionString). Malformed JSON logged + dropped to avoid poison-queue retry loops; transient repo errors propagate so the platform retries. - DI: handler registered as Singleton in Program.cs. Failure semantics: - Required-field-missing envelopes (Signal without SessionSignalOrdinal or SignalKind; DecisionTransition without StepIndex) → log warn, drop. These won't become valid on retry — avoiding the retry loop. - Transient Table Storage errors → rethrow. QueueTrigger platform retries up to 5 times by default, then moves to telemetry-index-reconcile-poison for manual investigation. Deferred to M5.d.4: - SessionsByStage stale-row pruning: when a session moves from Stage-X→Stage-Y, the old Stage-X row stays. Either query-side dedupe (per SessionId, max-Ticks RK) or reconcile-timer pruning handles this. Deliberately not solved in the handler to avoid a query+delete round-trip per Taken transition. - End-to-end dual-write verification tests (Azurite harness) are the M5.d.4 release gate before the flag is flipped. Tests (+10 in Functions) via capture-only FakeIndexTableRepository: - Signal happy path (1 SignalsByKind row). - Signal missing SessionSignalOrdinal / SignalKind → 0 rows (x2). - DecisionTransition Terminal+Taken+Classifier → 3 rows. - DecisionTransition Taken non-terminal no-classifier → 1 row (SessionsByStage only). - DecisionTransition dead-end with classifier → 2 rows (DeadEndsByReason + ClassifierVerdictsByIdLevel). - DecisionTransition dead-end without reason → 0 rows (PK-collision defense). - DecisionTransition missing StepIndex → 0 rows (all paths gated). - Unknown SourceKind → 0 rows. - Null envelope → 0 rows. Full Functions suite: 682 green (prev 672 + 10 new). Full solution build green.

Components: - ISignalRepository.QueryByTimestampAtOrAfterAsync + IDecisionTransitionRepository.QueryByTimestampAtOrAfterAsync: new cross-partition scans filtered on the Azure Tables system-managed `Timestamp` property. Bounded to maxResults=50000 with a warn-log on cap-reached so silent truncation can't masquerade as success. - IndexReconcileTimer: TimerTrigger on "0 0 */2 * * *" (same cadence as MaintenanceFunction). Scans the last 4h (window deliberately 2× the cadence so every primary row gets re-checked at least twice before falling out of range), builds envelopes via the existing IndexReconcileEnvelopeFactory, and hands them to the producer — reusing the M5.d.2 flag-gate + queue-failure-swallow semantics instead of duplicating them. - Testable core: RunReconcileAsync(cutoffUtc, CT) split out from the TimerTrigger entry so unit tests can drive with deterministic cutoffs without an Azure Functions host. - AdminConfigurationService.GetConfigurationAsync is now virtual — enables Moq-based mocking in timer flag-gate tests. Low-risk prod change (no existing caller relies on final). Release gate (Plan §M5-Pflicht line 1395): IndexDualWriteConsistencyTests verifies per-index-table that the captured index row's back-ref fields (TenantId, SessionId, StepIndex / SessionSignalOrdinal) plug directly into the primary repos' key builders to reconstruct the primary (PartitionKey, RowKey). The resubmit-idempotency test simulates a timer-triggered replay of the same primaries and asserts all duplicated rows collapse onto identical Index (PK, RK) pairs — which is exactly what the real TableIndexRepository's UpsertReplace does at the storage layer. Left deferred (not blocking M5 close): - SessionsByStage stale-row pruning: stage-X→Y transitions still leave an orphan row in {tenantId}_X. Either query-side dedupe (per SessionId, max-Ticks RK) or a follow-up pruner handles it. - Actual EnableIndexDualWrite=true flip: stays default-false until post-deploy verification runs. Producer + timer both no-op in the meantime, so the change is zero-risk on merge. - Cross-partition-scan perf: fine for current primary-table sizes; revisit if prod metrics after pilot show degradation. Tests (+10 in Functions): - 4 IndexReconcileTimerTests: flag-off short-circuits queries, flag-on with primary rows enqueues all envelopes, empty-window skips enqueue, ReconcileWindow=4h invariant. - 6 IndexDualWriteConsistencyTests: 5 per-index-table PK/RK back-ref (SignalsByKind + all 4 transition-derived indices) + 1 resubmit idempotency ensuring all duplicated rows collapse onto the same index keys. M5 status: M5.a + M5.b (+ 3 sub-commits) + M5.c (+ 3 sub-commits) + M5.d (+ 4 sub-commits) all complete. M5.d loop: Primary commit (M5.a) → Envelope enqueue (M5.d.2, flag-gated) → Queue → Handler (M5.d.3) → Index-Tables (M5.d.1) + 2h safety-net Timer (M5.d.4) reconciles missed envelopes. Full Functions suite: 692 green (prev 682 + 10 new). Full solution build green.

Without this change the entire M5.d pipeline was unreachable in production. Wire-up mirrors the existing allowAgentDowngrade toggle (closest analog — also a developer/ops-level bool with caveat copy): - types/adminConfig.ts: add optional enableIndexDualWrite field with a doc comment pointing at Plan §M5.d so future maintainers understand what toggling it does. - AdminConfigContext.tsx: add state + setter, hydrate from GET response (default false), include in save-spread, include in reset fallback, expose via context value + save-useCallback deps. - AdminConfigSettingsSection.tsx: add prop pair and a checkbox-style toggle below the ModernDeployment harmless-IDs input. Copy explains the 5 index tables + the 2h safety-net timer + warns that it should only be flipped after release-gate verification. - SectionGlobalSettings.tsx: destructure + forward the new prop pair. Round-trip is safe: GET (System.Text.Json, camelCase) emits enableIndexDualWrite, UI spreads it back into PUT body, Newtonsoft case-insensitive deserialization binds to EnableIndexDualWrite on the model — so an operator save no longer silently resets the flag. Verification: npx tsc --noEmit clean, vitest suite 168/168 green.

Tatsächlich persistiert sie collector-internal IME-Tracker-State: LogFilePositionTracker-Byte-Offsets, `SeenAppIds` (Phase-Isolation), komplette `AppPackageStateList` mit DO-Metriken + Install-Progress + AppType + AttemptNumber + DetectionResult + ErrorPatterns. Das ist peripheral capability per `feedback_v2_kernel_only_refactor` (App-Download-Monitor, Install-Monitor, Per-App-Summaries — Produkt-Kernfeatures), NICHT DecisionEngine-State. SignalLog-Replay deckt das NICHT ab. Ohne die Persistenz: nach Restart Byte-0-Re-Parse aller IME-Logs, Event-Duplikate, Phase-Bleed, verlorener In-Flight-Download-Progress. Ich hatte die Regel in meinem eigenen Plan-Doc zitiert und trotzdem angewandt — weil Kategorisierung nach Pfad ("Enrollment" im Ordner) statt nach Funktion (was persistiert die Datei?) erfolgte, Plan-Doc + Explore-Agent-Output ohne Kontrolle übernommen wurden, und weil `…` am Ende der Feedback-Liste nicht als "non-exhaustive" interpretiert wurde. -**Rule:** Vor jedem `rm`/`git rm` eines Files in V2.Core (insbesondere unter `Monitoring/Enrollment/`, `Monitoring/Transport/`, `Monitoring/Runtime/`): `Read` die Datei, frag "DecisionEngine-Concern (Stage, Hypothesis, Deadlines, Facts) oder Collector-Concern (Byte-Offsets, App-Progress, WMI-Cache, Phase-Isolation)?". Collector-Concern bleibt — egal wo die Datei im Pfad liegt. Zusatz-Check: "Was bricht nach Restart ohne diese Datei?" — wenn Re-Parse/Verlust-Progress/Phase-Bleed → Peripheral, bleibt. Plan-Doc + Explore-Agent sind Startpunkt, nicht Autorität. -**Severity:** PRODUCTION — hätte App-Tracking komplett zerschossen nach Agent-Restart. Gefangen durch User-Review vor Deploy. -**Reference:** [feedback_peripheral_classify_by_function.md](C:/Users/OliverKieselbach/.claude/projects/c--Code-GitHubRepos-Autopilot-Monitor/memory/feedback_peripheral_classify_by_function.md) - -### Timeline sequence must NEVER regress in the curated UI view (2026-04-04) -**What went wrong:** `groupEventsByPhase` was called without `preventPhaseRegression: true` for normal sessions and WhiteGlove pre-provisioning. A mid-enrollment reboot emits a new `agent_started` (Phase 0 = "Start"), which regressed the active phase back to Start, dumping post-reboot events (seq 173+) into the Start section — breaking the sequential appearance. -**Rule:** ALL `groupEventsByPhase` calls MUST use `{ preventPhaseRegression: true }`. The curated timeline sequence must appear continuous within each phase section. Reboots and agent restarts must NOT create phase regression — events stay in whatever phase was active before the reboot. -**Severity:** UX — confuses users, violates core timeline principle. - -### Table Storage mapping defaults must match domain defaults (2026-03-31) -**What went wrong:** Added `NtpServer` mapping with `?? ""` fallback. Existing tenants had no value stored → got empty string instead of `"time.windows.com"` → agent NTP check broke. -**Rule:** When adding missing Table Storage read mappings, the `??` fallback MUST match the domain/model default (check `AgentConfigResponse`, `GetAgentConfigFunction`, or the property initializer). Never use empty string as fallback for fields that have a meaningful default. -**Severity:** PRODUCTION — silently breaks agent functionality for all existing tenants. - -### PowerShell scripts deployed via Intune MUST be pure ASCII (2026-03-30) -**What went wrong:** Em-dash characters `—` (U+2014) and Unicode symbols (✓, →, ✗) in Bootstrap .ps1 scripts caused cascading PowerShell parse errors in production. The IME (Intune Management Extension) uses PowerShell 5.1 which reads scripts without BOM as ANSI — multi-byte UTF-8 chars get corrupted. -**Rule:** ALL `.ps1` files under `scripts/Bootstrap/` (and any other scripts deployed via Intune) MUST contain only ASCII characters (0x00-0x7F). No em-dashes, no Unicode symbols, no special quotes. Use `-` instead of `—`, `[OK]` instead of `✓`, etc. -**How to check:** `LC_ALL=en_US.UTF-8 grep -Pn '[^\x00-\x7F]' ` — must return no matches. -**Severity:** PRODUCTION BREAKING — agent installation fails completely on all devices. diff --git a/tasks/m2-copy-list.md b/tasks/m2-copy-list.md deleted file mode 100644 index d47f59b2..00000000 --- a/tasks/m2-copy-list.md +++ /dev/null @@ -1,187 +0,0 @@ -# M2 — V2.Core Copy List (Scan-Ergebnis, vor User-Signoff) - -**Status:** Scan abgeschlossen am 2026-04-20 (Explore-Subagent). **User-Signoff erhalten 2026-04-20: alle Empfehlungen (A1a, A2a, A3a, A4a, A5 SKIP) + A6 mit expliziter COPY-Direktive für alle fünf Helper.** Leitprinzip vom User festgelegt (siehe `feedback_v2_kernel_only_refactor.md`): **V2-Refactor ist kernel-only, keine Funktionalität verlieren.** - -Diese Datei ist das Vorab-Staging; nach Signoff wird der Inhalt in -`src/Agent/AutopilotMonitor.Agent.V2.Core/README.md` final übernommen und hier nur ein Verweis stehen bleiben. - ---- - -## Zusammenfassung - -| Kategorie | Anzahl | Entscheidung | -|---|---|---| -| COPY (M2, verbatim) | ~70 Dateien | Infrastruktur + 8 Decision-Collectors + 4 Telemetrie-Collectors + Gather/Analyzer | -| COPY + Mark for M4 Removal | ~4 Dateien | EventSpool, EventUploadOrchestrator, MonitoringService, EnrollmentCompletionHandler (transitional) | -| SKIP (V2 hat native Impl) | ~15 Dateien | CompletionStateMachine, CompletionGuards, EnrollmentTracker.CompletionLogic, IEnrollmentFlowHandler + Flows, WhiteGloveSignals | -| AMBIGUOUS | 6 Einträge | User-Entscheidung nötig (siehe Abschnitt unten) | - ---- - -## 1.

Build-Gate: Legacy + V2 beide grün From ee07059bc370618f88bd328fcfcd5ea9ef7d2c33 Mon Sep 17 00:00:00 2001 From: Oliver Kieselbach Date: Tue, 21 Apr 2026 14:13:07 +0200 Subject: [PATCH 58/61] fix(backend): harden /api/agent/telemetry batch validation (Codex Finding 3) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The ingest endpoint trusted the first item's PartitionKey for the whole batch and silently defaulted RowKey-driver fields to 0 when the agent envelope omitted them. Both paths can misroute data on the storage layer. 1. Cross-session guard: every TelemetryItemDto in a batch must share the same PartitionKey as items[0]. Without this, a mixed-session batch would be stamped with session-A's identity inside PersistItemsAsync and silently relocate session-B's signals/transitions into session-A's primary rows. Mismatch now returns 400 BadRequest with the offending index logged. Extracted as pure helper FindMismatchingPartitionKey so the guard is unit-testable without an HTTP harness. 2. RowKey-driver enforcement in TelemetryPayloadParser: - ParseSignal now rejects envelopes where SessionSignalOrdinal is absent or null (returns null → caller drops the item). A missing value would default to 0 and clobber a legitimate ordinal-0 row on UpsertReplace. Explicit ordinal=0 stays a valid value. - ParseTransition applies the same defense to StepIndex. - Distinguishes "key missing" from "key present with value 0" via JObject.TryGetValue + JTokenType check. Tests (+11 in Functions): - IngestTelemetryFunctionTests: empty batch, single-item batch, uniform batch, mismatch in middle, case-sensitive mismatch. - TelemetryPayloadParserTests: missing/null SessionSignalOrdinal on Signal → null; explicit ordinal 0 accepted; missing/null StepIndex on DecisionTransition → null; explicit StepIndex 0 accepted. Full Functions suite: 703 green (prev 692 + 11 new). Does not address Codex Findings 1 (V2 agent has no Signal/Transition upload path) or 2 (AdminAction=Succeeded mis-mapped to Failed locally) — those land in follow-up commits on this branch.

SignalIngress.Append wrote the signal to the local SignalLog and handed it to the reducer; DecisionStepProcessor journaled each transition locally. Neither called into ITelemetryTransport, so the entire M5 backend ingest pipeline for these two telemetry kinds (Signals/DecisionTransitions primary tables, Inspector reads, ReducerVerifier, the M5.d index fan-out + timer) had zero agent traffic. Adds the missing emitters — analogous to TelemetryEventEmitter — and wires them through EnrollmentOrchestrator: - TelemetrySignalEmitter (V2.Core/Telemetry/Signals/): serializes a DecisionSignal with Newtonsoft + StringEnumConverter and builds a TelemetryItemDraft with Kind=Signal, PK={tenant}_{session}, RK=SessionSignalOrdinal.ToString("D19") — matches TableSignalRepository.BuildRowKey for idempotent UpsertReplace. - TelemetryTransitionEmitter (V2.Core/Telemetry/Transitions/): same contract for DecisionTransition; RK=StepIndex.ToString("D10"). Wiring: - SignalIngress accepts an optional TelemetrySignalEmitter. After the local SignalLog.Append succeeds — before the reducer runs — the ingress enqueues the signal on the transport. Enqueue failures are swallowed: the local SignalLog is authoritative per §2.7c / L.1, and the reducer must still see the signal even if the upload path is broken. - DecisionStepProcessor accepts an optional TelemetryTransitionEmitter. After the Journal.Append try-block succeeds (and before the effect runner), it enqueues the transition. Same swallow semantics. Journal failures still rethrow as before, so a failed-journal step can never leak a ghost row to the backend. - EnrollmentOrchestrator constructs both emitters alongside the existing TelemetryEventEmitter (step 4 of the startup sequence) and passes them into steps 8 + 10. Both emitter constructor params are optional to keep pre-M5 test constructors compilable without touch-up. Tests (+26 across two assemblies): V2.Core.Tests (+21): - TelemetrySignalEmitterTests (6): correct keys + kind, StringEnumConverter for DecisionSignalKind, PascalCase field names the backend parser reads, D19 padding survives long.MaxValue, null-rejection, ctor argument validation. - TelemetryTransitionEmitterTests (7): same surface + dead-end case preserves DeadEndReason + Taken=false, nested ClassifierVerdict emits ClassifierId/Level that the backend parser can read. - SignalIngressUploadPathTests (4): emit happens per signal, monotonic RowKey padding, null emitter preserves pre-M5 behaviour, transport throw is swallowed (reducer keeps running). - DecisionStepProcessorUploadPathTests (4): emit happens per successful journal, null emitter preserves pre-M5 behaviour, journal failure prevents emit (no ghost rows), transport throw is swallowed (effects still run + CurrentState advances). Functions.Tests (+5) — the Codex-requested cross-layer gate: - TelemetryWireRoundTripTests: a DecisionSignal / DecisionTransition serialized with the exact JsonSerializerSettings the agent emitter uses (StringEnumConverter + NullValueHandling.Ignore) is parsed by TelemetryPayloadParser.ParseSignal / ParseTransition back into a SignalRecord / DecisionTransitionRecord with every field preserved. Includes explicit-zero edge cases (ordinal=0, stepIndex=0) so the Finding-3 required-field guards don't trip on legitimate agent traffic. The backend project can't reference the net48 agent assembly directly, so the test replicates the wire contract via shared DecisionCore types + the agreed serializer settings — any drift between agent and backend breaks this test immediately. Suites: V2.Core 406 green (prev 385 + 21 new). Functions 708 green (prev 703 + 5 new). Full solution build green. Does not address Codex Finding 2 (AdminAction=Succeeded mis-mapped to Failed locally) — lands in the next commit on this branch.

The M4.6.ε ServerAction synthesis in Program.cs already copied the adminOutcome value into the terminate_session ServerAction's Params bag, but the terminate_session callback that fed the TerminationHandler hard-coded EnrollmentTerminationOutcome.Failed regardless of what adminOutcome said. Downstream consequences of the hard-coded Failed: - FinalStatusBuilder.MapOutcome rendered "Failed" in the SummaryDialog even when the operator had explicitly marked the session Succeeded. - EnrollmentTerminationHandler's DiagnosticsUploadMode.OnFailure gate fired a diagnostics package for every admin-override, regardless of actual outcome. Fix: - New Program.ServerActionSynthesis.cs partial (public static class Program, matches existing declaration) carrying a pure static helper MapAdminOutcome(IReadOnlyDictionary? params) → EnrollmentTerminationOutcome. Case-insensitive "Succeeded" → Succeeded; missing/null/empty/any-other-value → Failed (default-failure-safe for kill-signal-driven synthesis that never sets adminOutcome). - The terminate_session callback in Program.cs now calls the helper and threads the mapped outcome into EnrollmentTerminatedEventArgs. Log message extended to include the mapped outcome so ops can correlate the server-side override with the local termination result. Reason stays DecisionTerminalStage. A distinct AdminAction reason would need a DecisionCore enum extension — out of scope for this fix. What Codex flagged concretely (Mark-Succeeded → visible as Failed) is now addressed. Tests (+10 in V2.Core.Tests): AdminActionOutcomeMappingTests - "Succeeded" → Succeeded - Case-insensitive variants (succeeded / SUCCEEDED / mixed case) - "Failed" → Failed - Unknown values (TimedOut / weird-future / empty) → Failed - Missing adminOutcome param (kill-signal case) → Failed - Null params dict → Failed Accesses the helper through InternalsVisibleTo("AutopilotMonitor.Agent.V2.Core.Tests") that was already set on the V2 agent assembly. Suites: V2.Core 416 green (prev 406 + 10 new). Full solution build green. This closes the last of the three Codex findings from the PR-43 review. Remaining review comment on cross-layer test coverage is already satisfied by the TelemetryWireRoundTripTests added in commit b6ea13f1.

Before: the provider was constructed with no seed, so on agent restart its counter began at -1 and the first post-recovery signal landed with SessionTraceOrdinal=0 — guaranteeing a collision with whatever trace ordinal the previous session had already persisted. The collision surfaces at the Inspector (cross-type correlation fields) and in any downstream replay that joins on SessionTraceOrdinal. Interface additions (ISignalLogWriter + IJournalWriter): - long LastTraceOrdinal { get; } max SessionTraceOrdinal observed across persisted entries; -1 on an empty log. Distinct from LastOrdinal / LastStepIndex which track the kind-specific monotone counters; SessionTraceOrdinal is the session-wide correlation counter shared across Event + Signal + Transition (DecisionSignal §2.2). Implementations (SignalLogWriter + JournalWriter): - Renamed ScanHighestOrdinal / ScanHighestStepIndex into a shared ScanRecoveryState() that populates both fields in a single JSONL pass on construction. Same stop-at-corrupt-tail semantic as before (recovery §2.7). The Append path also tracks the max inline so subsequent queries after a writer is in use stay O(1). EnrollmentOrchestrator.Start (step 9): var traceSeed = Math.Max( Math.Max(_signalLog.LastTraceOrdinal, _journal.LastTraceOrdinal), _spool.LastAssignedItemId); _traceCounter = new SessionTraceOrdinalProvider(seedLastAssigned: traceSeed); All three sources are consulted because each can hold a trace ordinal the other two missed: - SignalLog may contain signals whose spool-enqueue later failed (the emit path swallows transport exceptions per SignalIngress §2.7c). - Journal likewise for transitions with failed spool-enqueue. - Spool.LastAssignedItemId is the single-source-of-truth for everything that reached the transport — including Events that bypass the provider entirely but still share the TraceOrdinal space. Test harness: - FakeJournalWriter gains a LastTraceOrdinal property (computes max from its captured Appended list) so processor-level tests keep compiling. Tests (+6 in V2.Core.Tests): - SignalLogWriter: empty → -1; max across out-of-order trace ordinals (not just the last appended); restart rescans on-disk file to recover max. - JournalWriter: same three cases. Both empty-log tests exist so the orchestrator seed falls through cleanly on first-ever startup (seedLastAssigned=-1 → Next()=0 matches the fresh-session invariant). Suites: V2.Core 422 green (prev 416 + 6 new). Full solution build green.
