The 2026-09-01 WG-seal soak on post-SignalIngress-fix builds (memory:
project_wg_seal_postfix_soak_residual) found sessions whose DecisionEngine
never sealed Part 1 while the agent kept running for hours - and telemetry
could not distinguish a frozen ingress worker from a deliberate Weak
sealing-classifier verdict, because the metrics snapshots carried no
pipeline counters at all.
Every agent_metrics_snapshot now carries the block. The fields are MONOTONIC
totals plus a monotonic queue peak - deliberately no momentary queue length:
a snapshot samples the integral, so any two snapshots prove whether the
worker ran in between (a frozen worker keeps signal_pending_count growing
while processed/applied stand still; a momentary gauge would alias between
ticks). Same field pattern the snapshot already uses for the spool
(spool_total_enqueued_count / spool_peak_pending_item_count).
- signal_last_ordinal / signal_processed_total (new ProcessedSignalCount) /
signal_pending_count / signal_reentrant_total: SignalIngress worker
progress; signal_queue_peak is a new lock-free Interlocked-max recorded in
Post (fast + slow path; worker-local follow-up items deliberately excluded)
- decision_stage + decision_last_applied_ordinal: from the immutable
DecisionState - answers the WG question directly ("minutes after the
tracker's whiteglove_complete and still not WhiteGloveSealed")
- wg_sealing_level / wg_sealing_score: only after the sealing classifier
produced at least one verdict (key ABSENCE, not Unknown/0 noise, for every
non-WG session) - separates "classifier said Weak" from "never ran"
Wiring is a read-only probe chain following the imeTrackerHealthProbe
pattern: EnrollmentOrchestrator passes () => _processor?.CurrentState into
IComponentFactory.CreateCollectorHosts (new optional decisionStateProbe;
test fakes updated), PeriodicCollectorLifecycleHost combines it with its
existing concrete-SignalIngress reference in BuildSignalPipelineProbe, and
AgentSelfMetricsCollector writes the fields fail-soft (a throwing probe
degrades to a snapshot without the block - pinned by test). The snapshot
event travels the collector/event path, which is independent of the signal
pipeline it measures - field-proven by the freeze cases, whose perf/metrics
events kept flowing while the engine stood still.
No backend/web/MCP change needed: no new event type, DataJson is free-form.
Tests: 5 new collector facts (full block, absence semantics x2, fail-soft,
no-probe compatibility) + 2 new SignalIngress facts (processed total stable
across drain; queue peak survives the queue draining - the property a
momentary gauge would not have). Agent suite 2812 green, solution builds
with 0 warnings.

EffectRunner posts ClassifierVerdictIssued from inside DecisionStepProcessor.ApplyStep,
i.e. on the SignalIngress worker thread. With the bounded channel (256) full, Post's
back-pressure slow path blocked the channel's only consumer as a producer: nothing could
ever drain, every collector Post blocked behind it, and the whole decision/monitoring
pipeline froze silently until the max-lifetime watchdog.
Post now detects a call from the worker thread itself and routes the item to a
worker-local follow-up queue that WorkerLoop drains (iteratively, ahead of the channel)
right after the current item. Same processing path — ordinals, SignalLog, emit,
reduce, ApplyStep — just never blocking. Worker posts are accepted during the Stop
drain too, since the verdict belongs to the step being finished. ReentrantPostCount
exposed for observability/tests.
Tests: full channel + worker post releases a blocked foreign producer and processes the
verdict before the next channel item (fails against the previous code by hanging);
follow-up chain drained in order without recursion; verdict posted during Stop drain is
not lost. Docs: agent/decision-engine.md, agent/overview.md, log.md.

IME never writes its "Completed user session" line when the user has no
assigned Win32 apps - its zero-app branch returns before that statement
(ApplicationPoller.cs:713-721, identical in 1.80/1.83/1.97/1.104). So
ImeUserSessionCompletedUtc stayed null, every arm of
ShouldTransitionToAwaitingHello was unsatisfiable, and the 30-min
advisory_completion backstop resolved healthy enrollments as
esp_exit_without_completion_evidence. One tenant: 10 of 30 sessions in a week,
all false positives - DAD-validated desktop, Hello provisioned, RealmJoin still
installing. Every Succeeded session there carries ime_user_session_completed;
not one of the failed ones does.
IME-USER-SESSION-ZERO-APPS reads the line IME does write there and routes it
through the same OnUserSessionCompleted callback. That is IME's own verdict
rather than a weakened gate: the zero-app branch locks the ESP in with an empty
application list, and the sibling emit site returns ProvisioningComplete right
after logging it. Guarded to the AccountSetup phase so it cannot burn the
adapter fire-once flag on a pre-sign-in timestamp, and replayed on the phase
transition when the observation predates the phase marker. AreUserEspAppsSettled
accepts an empty app list only with that explicit observation, never on
emptiness alone.
Second, independent defect: advisory_completion (30 min) overran the RealmJoin
completion gate, which deliberately holds the session and carries its own
bounded resolution (60 min from detection, activity-extended, 4 h cap). One
session installed 25 RealmJoin packages inside the window, the last 2 min before
the failure, while completion_waiting still read "waiting on:
realmjoin_resolution". The handler now re-arms while that gate is closed and its
own deadline is still armed; convergence comes from the gate itself, which
always ends with an Outcome set.
ime_user_session_completed gains an evidence field (zero_user_apps_enumerated /
user_session_completed) - no new event type, so the Constants ->
resource-catalog -> shared-manifests triple stays untouched. The pattern ships
via the config API and reaches existing agents, where an unknown action is a
single Debug line; the behaviour needs the agent release.
Build 0 warnings. DecisionCore 558/558, V2.Core 2530/2530, Backend 4634/4634,
MCP event-types-drift 6/6.

The 60-min RealmJoinTimeout deadline arms at RJ detection (the RJ agent MSI
install during DeviceSetup) and used to cut off monitoring mid-install: report
55e6afd61c9d (session 46a96078) lost the tail of a large package catalog whose
last observed package completed 3 seconds before the deadline, with the first
deployment only starting 16 minutes into the window.
When the deadline now fires with LastDeploymentPhase 100/101 and deployment
activity (phase change or package observation, persisted restart-safe in
RealmJoinFacts.LastActivityUtc; the detection-time phase capture deliberately
does not count) inside the last 60 min, the handler re-arms to
lastActivity + 60 min instead of timing out — Info event
realmjoin_timeout_extended — clamped at an absolute cap of detection + 4 h.
realmjoin_timeout carries a reason payload (hard_timeout / inactivity /
absolute_cap); a fire of a deadline incarnation superseded by a re-arm
dead-ends via the OccurredAtUtc == DueAtUtc scheduler contract. The idle case
(no activity ever) still times out at 60 min, and phase-200/210 activity never
extends. Packages are only registry-visible at completion, so the inactivity
window keeps the full original 60 min.

An interactive logon during the RealmJoin first deployment (phase 100/101)
makes RJ reclassify the run as a secondary-user deployment, whose branch
writes 200/210 and never CompletedFirstDeployment (110) — no crash, no
reboot request. The V2 completion gate waited for exactly 110, so these
sessions hung until the 60-min hard timeout (session 224b2087; siblings
558bf067/3cc18724 delayed ~50 min the same way).
- promote realmjoin_phase_changed to a typed RealmJoinPhaseChanged signal
(dual-emitted by the adapter) so RealmJoinFacts.LastDeploymentPhase is
persisted across agent restarts
- abort rule: prev in {100,101} and current in {200,210} with no outcome
yet -> emit realmjoin_first_deployment_incomplete (Warning), cancel the
hard-timeout deadline, release the gate with outcome
FirstDeploymentIncomplete; also evaluated on the RealmJoinDetected
replay path (restart swallows the transition)
- deliberately NOT triggered by 101->0 (RJ service restart may still
complete the first deployment) nor by a first observation of 210
(session 6f1959c0: RJ already completed before agent boot)
- fix realmjoin_timeout always claiming "last phase: 0" - the persisted
phase now feeds the message
- backend EnrollmentTimeoutClassifier counts the new event as a gate
terminal; MCP resource catalog dual-synced
- CompleteIfDeferredOrBookkeep widened to a leading-effect list
Verified by replaying session 224b2087's signal log: gate releases at
15:05:17 (101->200) instead of hanging until the 15:54 deadline.

GitHub resolves /-prefixed links against the repo root (missing /docs),
so cross-doc navigation broke. Switched all agent docs to standard
relative links and updated the bundle convention in index.md + CLAUDE.md.
