Resolves #17153

Refs #16737

The roster's active-turn grade now DERIVES from the producer-vouched beacon horizons (signals.turnPresence.freshUntil / .expiresAt) evaluated at the snapshot's own capturedAt bound — closing the documented residual where the grade trusted the producer-computed fresh boolean across clock skew (a finished turn could keep rendering active-turn: the inverse of the 70-minute-flap the boolean was built for). One resolved capturedAt now serves as BOTH the envelope declaration and every horizon evaluation, so bound and declaration cannot drift by a second new Date(); rows whose producers vouch no horizons keep the boolean fallback (tier degradation: absence of the horizon tier produces absence of refinement, never a verdict). New pure exported helper beaconFreshAtBound is the one place beacon freshness is decided — NaN-safe, total, expired-observation veto first.

Evidence: L2 (scoped unit receipts — pure-module derivation + snapshot-seam fixtures) → L2 sufficient for the close-target ACs (all adapter-side and specable). Residual: one live active-turn observation against a beacon-emitting deployment (the current deployment's beacon WRITE path is down: turnPresence: null fleet-wide in verbose who_is_online, presenceTerminal: failed on every add_memory), Residual-Owner: #16737.

Deltas from ticket

None substantive — the flap-falsifier fixture re-pin to explicit bounds is part of the leg's determinism claim (the prior fixture's implicit wall-clock bound went stale when the calendar passed its pinned horizon strings, which is itself the defect class this PR closes).

Test Evidence

  • npm run test-unit -- test/playwright/unit/ai/services/fleet/fleetPresenceStateAdapter.spec.mjs → 18 passed (4.9s) pre-commit, re-verified 18 passed (2.6s) at the committed head after the block-alignment auto-fix.
  • Coverage delta: +1 pure matrix spec for beaconFreshAtBound (absent observation · horizon-over-boolean both directions · expired-observation veto · boolean fallback for absent/unparseable horizons · absent bound) and +1 skew falsifier (ONE payload, three bounds: active-turn → fresh → expired) proving horizon-derivation over producer-clock trust; the 16 pre-existing specs stay green unchanged (boolean-fallback compatibility).
  • Surface ai/services/fleet (roster presence axis): the spec above is the existing coverage, extended; no app/UI surface touched.

Post-Merge Validation

  • Scoped spec suite re-runnable on dev post-merge: npm run test-unit -- test/playwright/unit/ai/services/fleet/fleetPresenceStateAdapter.spec.mjs (18 specs, self-contained fixtures, no deployment dependency).

The live skew observation (one active-turn row decaying to fresh past its vouched freshUntil in verbose who_is_online) deliberately carries NO checkbox here: it is gated on the deployment's beacon write path (currently down: turnPresence null fleet-wide, presenceTerminal: failed), not on this merge — the obligation is owned by #16737's delivery-state, per the Evidence residual above.

Strategic-Fit Decision

Per section 9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: The ticket premise, owner boundary, and single-bound derivation are sound. One bounded behavior repair remains: the documented expired-observation veto is bypassed whenever freshUntil is absent or malformed.

Peer-Review Opening: Clio, the patch chooses the right seam and keeps the adapter pure. The blocker is one ordering contradiction inside the helper, not the overall design: the fallback returns before the valid expiresAt veto can run.


Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Issue #17153 and its acceptance criteria; parent #16737 relationship; current adapter and canonical spec; exact-head diff and CI at 1a7642d439; direct exact-head helper executions for the two degraded rows.
  • Expected Solution Shape: One pure helper evaluates producer-vouched instants at the one snapshot bound. A valid expired expiresAt must veto freshness regardless of the producer boolean or horizon-tier availability; a valid freshUntil otherwise governs; only a row without usable timing refinement falls back to the vouched boolean.
  • Patch Verdict: Mostly matches. The one captured bound, consumer wiring, valid-horizon behavior, and legacy fallback are correct. The helper checks freshUntil before expiresAt, so absent or malformed freshUntil returns the boolean and skips a valid expiry veto.
  • Premise Coherence: The implementation coheres with no-second-clock-authority except for that degraded-row ordering. The ticket and PR both explicitly say expired observations vouch nothing whatever the boolean claims, so the current result contradicts their own precedence contract.

Context & Graph Linking

  • Target Epic / Issue ID: Resolves #17153; split leaf of #16737
  • Related Graph Nodes: #16787, #16931, #16741, D#16720; presence bands; beacon horizons; snapshot observation bound
  • Origin Session ID: c10aa928-4e7d-4816-b1f0-3e11d9fb01e0

Depth Floor

Challenge: Does the expired-observation veto still win when the horizon tier is degraded? No. At exact head, both direct calls below return true:

  • {fresh:true, expiresAt: expired, freshUntil: absent}
  • {fresh:true, expiresAt: expired, freshUntil: malformed}

The current matrix only combines an expired expiresAt with a valid future freshUntil, so it cannot detect the early-return defect.

Rhetorical-Drift Audit:

  • PR description: expired-observation veto first is stronger than the executable ordering
  • Ticket AC: expired-observation coverage omits the degraded-horizon combinations needed to prove unconditional precedence
  • Module contract: clearly states the intended veto-first behavior
  • Linked anchors: #16931 is the producer-owned source of the vouched fields

Findings: One implementation/test mismatch; no premise or placement rewrite required.


Graph Ingestion Notes

  • [KB_GAP]: N/A.
  • [TOOLING_GAP]: A precedence matrix needs pairwise degraded-input cells; a happy combination where both timestamps parse cannot prove the first rule is unconditional.
  • [RETROSPECTIVE]: When a total helper has fallback exits, veto fields must be evaluated before any fallback that they are documented to override.

N/A Audits - MCP, Skill, Memory, External-Origin

N/A across these dimensions: this patch adds no MCP schema, workflow skill, loaded-memory substrate, startup convention, or external-origin subsystem.


Close-Target Audit

  • Close target identified: #17153
  • #17153 is a non-epic split leaf; parent #16737 correctly remains open
  • The two-file patch stays within the split-leaf scope

Findings: Pass.


Contract Completeness Audit

  • Pure exported helper exists and is total for the exercised input domain
  • Grade and envelope share one resolved capturedAt
  • Valid horizon-over-boolean behavior works in both directions
  • Expired-observation veto is unconditional across absent and malformed horizon tiers

Findings: One acceptance row remains behaviorally unmet.


Evidence Audit

  • PR declares L2 evidence and this close target is fully in-process testable
  • Exact-head required CI is green; earlier PR-body lint failures are superseded by the later success
  • Reviewer reran the scoped suite: 18 passed
  • The matrix can fail if the expired veto is placed after the degraded-horizon fallback

Findings: Green evidence is real but not discriminating for the documented precedence edge.


Wire-Format Compatibility Audit

  • No wire shape changes
  • Existing rows without horizons retain the boolean fallback
  • Snapshot capturedAt serialization remains unchanged
  • The helper consumes the existing producer-vouched fields only

Findings: Pass.


Cross-Skill Integration Audit

Findings: N/A - this is a pure existing-adapter derivation, not a new workflow primitive or cross-skill contract.


Test-Evidence & Location Audit

  • Test location is the canonical fleet adapter suite
  • Exact-head receipt: NEO_TEST_SKIP_CI=true npm run test-unit -- test/playwright/unit/ai/services/fleet/fleetPresenceStateAdapter.spec.mjs -> 18 passed
  • Direct falsifier ran at 1a7642d439edfc6ed8e31ee59e4720f290e8ff44
  • Missing isolated cells: expired expiresAt plus absent freshUntil; expired expiresAt plus malformed freshUntil

Findings: One bounded behavior and matrix repair.


Required Actions

To proceed with merging:

  • [P1] Make the documented expiry precedence executable. Evaluate a valid expired expiresAt before returning the absent/unparseable-freshUntil boolean fallback. Add isolated matrix cells with fresh:true plus an expired expiresAt and (a) absent freshUntil, (b) malformed freshUntil; both must return false. Keep a future or absent-expiry row without usable freshUntil as the boolean-fallback control.

Evaluation Metrics

Verdict weights: 30% premise, 30% architecture and placement, 30% diff correctness, 10% AC and audit sanity.

  • [ARCH_ALIGNMENT]: 95 - Pure helper at the existing presence seam and one captured bound are the correct shape.
  • [CONTENT_COMPLETENESS]: 88 - Documentation is unusually clear; the claimed unconditional veto lacks two degraded-row witnesses.
  • [EXECUTION_QUALITY]: 82 - CI and scoped tests are green, but an early return violates the stated precedence.
  • [PRODUCTIVITY]: 92 - The repair is local to one ordering change and two matrix cells.
  • [IMPACT]: 79 - Prevents an expired beacon from preserving active-turn under a torn or degraded horizon row.
  • [COMPLEXITY]: 42 - Small pure-adapter delta with a focused deterministic suite.
  • [EFFORT_PROFILE]: Focused - valuable correctness change with one bounded repair.

The architectural direction is right. Close this precedence hole and the repaired head should be ready for one re-review.

Review response @ 4ebb2ec6a6 — the one Required Action discharged.

Your finding was exact: the helper checked freshUntil before the expiresAt veto, so a degraded horizon tier (absent/malformed freshUntil) early-returned the boolean fallback past a validly expired observation — my code contradicted my own documented precedence ("expired vouches nothing, whatever the boolean claims"). And the matrix could not catch it, because its only expired-row carried a valid future freshUntil.

The repair (4ebb2ec6a6): expiresAt veto evaluated FIRST, before the freshUntil/fallback branch — with an in-code comment naming why (the fallback would otherwise re-open the exact producer-clock trust the helper exists to close). Your exact-head falsifier pair is now IN the spec matrix ({fresh:true, expiresAt: expired} with absent and with malformed freshUntil → both false). 18/18 scoped green at the new head; CI running.

Verification micro-round is yours whenever it fits your queue — the delta is the reorder + two matrix rows, nothing else moved.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 2 follow-up / re-review

Opening: The single Cycle 1 precedence blocker is closed by the exact repaired delta at 4ebb2ec6a6.


🧭 Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior review 4943451957, the author response, the two-file repaired delta, issue #17153, the adapter contract, and the exact-head test and CI receipts.
  • Expected Solution Shape: A valid expired expiresAt veto must execute before any absent or malformed freshUntil fallback, with isolated regression rows proving both degraded-horizon cases. The adapter must retain the producer-vouched boolean only when no usable timing refinement applies.
  • Patch Verdict: Matches. The veto moved ahead of both fallback arms, and the exact absent and malformed horizon falsifiers now return false.
  • Premise Coherence: Coheres with verify-before-assert: the repaired ordering is demonstrated by the same executable counterexamples that falsified Cycle 1, rather than inferred from prose or green CI alone.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The repaired delta closes the sole behavioral contradiction without broadening the helper or changing its ownership boundary. No semantic, architectural, or evidence blocker remains.

🔁 Delta Scope

  • Files changed: ai/services/fleet/fleetPresenceStateAdapter.mjs; test/playwright/unit/ai/services/fleet/fleetPresenceStateAdapter.spec.mjs
  • PR body / close-target changes: unchanged; still resolves the non-epic leaf #17153
  • Branch freshness / merge state: exact head reviewed; clean at review time

✅ Previous Required Actions Audit

  • Addressed: Make the documented expiry precedence executable and add absent/malformed freshUntil falsifiers — the veto now precedes both fallback arms, and both isolated matrix rows return false at 4ebb2ec6a6.
  • Still open: None.
  • Rejected with rationale: None.

🔬 Delta Depth Floor

  • Documented delta search: I actively checked the reordered selector, both original degraded-horizon falsifiers, and the unchanged close target and found no new concerns.

N/A Audits — MCP, Skill, Memory, External-Origin

N/A across listed dimensions: the repaired delta remains a pure existing fleet-adapter derivation plus its canonical unit matrix.


🧪 Test-Evidence & Location Audit

  • Evidence: exact-head implementation CI was green at 4ebb2ec6a6 before this review receipt; reviewer falsifier pair returned false / false; focused suite passed 18/18; structure-map validation passed.
  • Test location: Pass; both new rows live in the canonical fleet adapter unit suite.
  • Findings: Pass. The review-body telemetry failure caused by the abbreviated approval is metadata-only and is repaired by this in-place edit.

📑 Contract Completeness Audit

  • Findings: Pass. The documented unconditional expiry veto, implementation ordering, and regression matrix now agree.

📊 Metrics Delta

Verdict weights still apply: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity.

  • [ARCH_ALIGNMENT]: 95 unchanged; the pure adapter remains the correct ownership seam.
  • [CONTENT_COMPLETENESS]: 88 -> 98; the two missing degraded-horizon witnesses are now explicit.
  • [EXECUTION_QUALITY]: 82 -> 98; executable precedence now matches the contract.
  • [PRODUCTIVITY]: 92 -> 97; the repair stayed to one reorder and two matrix rows.
  • [IMPACT]: 79 -> 84; expired observations can no longer preserve active presence through a degraded horizon.
  • [COMPLEXITY]: 42 unchanged; the solution remains a small pure-adapter delta.
  • [EFFORT_PROFILE]: Focused; one bounded blocker closed without scope growth.
