PR Review Summary
Status: Request Changes
🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Request Changes
- Rationale: The producer-field addition is the right small shape, but the existing projection condition makes the ticket's per-row wire contract false for the most important positive case. This is one local, repairable consumer-boundary defect, not a Drop+Supersede premise failure.
Peer-Review Opening: The additive getter change is clean and preserves legacy callers. I found one production-path gap that prevents it from delivering the banding authority this ticket exists to expose.
🧭 Patch-Blind Premise Snapshot
- Inputs Read Before Patch: #16931, the two changed files, exact-head
TurnPresenceService, exact-headWakeSubscriptionService.whoIsOnline/_projectAgentLiveness, the existing verbose-roster tests, and the declaredwho_is_onlineOpenAPI response. - Expected Solution Shape: The beacon producer must vouch its own horizons, and every verbose roster row with an active beacon must carry that observation. Liveness precedence may use the beacon only as a rescue, but observation must not disappear merely because
add_memoryis also fresh. - Patch Verdict: Partially matches. The getter returns exact stored horizons and honest nulls, but the unchanged consumer calls it only inside
if (!activity?.fresh), so fresh-activity rows omitsignals.turnPresenceentirely. - Premise Coherence: Cohesive with verify-before-assert at the producer boundary, but incomplete at the public consumer boundary: the diff verifies the helper while the close-target asserts a plane-level per-row fact.

🔬 Depth Floor
Challenge: I challenged the zero-projection-change premise with the coexistence case the band vocabulary needs: fresh add_memory activity plus a fresh active-turn beacon. Exact-head WakeSubscriptionService.mjs:799-806 never reads the beacon in that case, so the verbose row has no horizons.
Rhetorical-Drift Audit:
- PR description: framing matches what the diff substantiates (no overshoot)
- Anchor & Echo summaries: precise codebase terminology, no source-snapshot overshoot
-
[RETROSPECTIVE]tag: N/A — none added - Linked anchors: #16737/#16927 establish the producer/consumer split
Findings: The PR body and new JSDoc say verbose rows carry the projection per row, but exact code only carries it when activity is absent/stale. That drift is the Required Action below.
🧠 Graph Ingestion Notes
[KB_GAP]: None.[TOOLING_GAP]: The new test stops at the getter; no exact-head test invokes the public verbose projection with both fresh signals present.[RETROSPECTIVE]: Observation and verdict precedence are different concerns. A lower-precedence signal may remain observable even when it does not decide the verdict.
🎯 Close-Target Audit
- Close-targets identified: #16931
- #16931 is not epic-labeled
Findings: #16931 AC1/AC2 are met. AC3 is not met for fresh-activity rows, so Resolves #16931 is premature at this head.
📑 Contract Completeness Audit
- Originating ticket contains a formal Contract Ledger matrix
- Implemented diff matches the full consumed contract
Findings: The ticket has an explicit bounded AC surface but no formal ledger matrix. The release blocker is behavioral rather than paperwork: the per-row consumer contract itself is incomplete.
🪜 Evidence Audit
- PR body declares achieved and required evidence classes
- Achieved evidence closes every non-deferred AC
- Post-merge deployed observation is named as residual
- No L2 evidence is promoted to L4
Findings: Getter-level L2 evidence does not cover AC3's real verbose-wire projection. The named coexistence case remains untested and false.
N/A Audits — 📡 🛂 🧠
N/A across listed dimensions: no OpenAPI description, major subsystem/provenance surface, or turn-loaded substrate is modified.
🔌 Wire-Format Compatibility Audit
The change is additive under the existing open signals object and preserves legacy nulls. Compatibility is sound where the object is emitted; completeness is not, because the object is conditionally absent despite an active beacon.
🔗 Cross-Skill Integration Audit
- No new MCP tool or workflow convention is introduced
- Existing
who_is_onlinedocumentation already owns the verbose signal surface - The existing projection test suite proves the new nested fields reach that surface
Findings: Same behavioral/test gap as the Required Action; no separate skill-documentation action.
🧪 Test-Evidence & Location Audit
- Execution evidence: exact-head required CI is 18/18 green at
1bf8c5ddacfdc6578c885b10446cde4af4911bed - Reviewer falsifier: exact production branch at
WakeSubscriptionService.mjs:799-806; fresh activity skipsgetFreshTurnPresence, so horizons are absent - Test location is correct
- The test reaches
whoIsOnline({verbose:true})and proves the coexistence case
Findings: CI is green because the added test exercises only TurnPresenceService.getFreshTurnPresence; the public consumer path remains unfalsified.
📋 Required Actions
To proceed with merging, please address the following:
- Separate beacon observation from beacon verdict precedence. Read and assign the active beacon to
signals.turnPresencefor every active roster row, while retaining the existing rule that it rescues the online verdict only when activity is not fresh. Add a realwhoIsOnline({verbose:true})regression with freshadd_memoryactivity plus a fresh beacon and assert both horizons reach the row; keep stale/no-beacon and legacy-null controls.
📊 Evaluation Metrics
[ARCH_ALIGNMENT]: 86 - Correct authority and additive surface, but observation is still coupled to verdict precedence in the consumer.[CONTENT_COMPLETENESS]: 80 - Getter JSDoc is strong; the per-row claim and AC3 evidence overstate production reach.[EXECUTION_QUALITY]: 84 - Getter implementation is precise, but the missing coexistence path leaves the public behavior incomplete.[PRODUCTIVITY]: 84 - Small useful delta; one bounded consumer repair should converge it.[IMPACT]: 82 - Enables banded presence only after every active beacon is actually observable.[COMPLEXITY]: 96 - Minimal additive fields with no compatibility churn.[EFFORT_PROFILE]: Quick Win - One consumer-branch separation and one production-path test remain.
The producer half is right; close the observation/precedence coupling and this should be approval-ready in one repair. 📐

PR Review Follow-Up Summary
Status: Approve
Cycle: Cycle 2 re-review
Opening: 📐 Observation and verdict precedence are now separated at exact head 90169af638: every active beacon is projected, while fresh activity still retains verdict priority. The prior per-row wire blocker is closed.
🧭 Patch-Blind Premise Snapshot
- Inputs Read Before Patch: Prior review
PRR_kwDODSospM8AAAABJCn3eQ; live #16931; exact-headTurnPresenceService,WakeSubscriptionService, verbose-roster projection tests, and hosted checks. - Expected Solution Shape: Read active beacon state independently for every roster row, expose its producer-owned horizons under
signals.turnPresence, and use it only as the existing rescue input when higher-precedence activity is not fresh. - Patch Verdict: Matches. Beacon observation is unconditional; online-verdict rescue remains conditional; the real coexistence test proves fresh activity and a fresh beacon both remain visible without letting the beacon override the verdict.
- Premise Coherence: The repair aligns with verify-before-assert by preserving the lower-precedence signal as observable evidence rather than erasing it when another signal decides the outcome.
🪜 Strategic-Fit Decision
- Decision: Approve
- Rationale: The sole prior behavior blocker is closed and every exact-head check is green. No architecture, compatibility, safety, or evidence blocker remains.

🔁 Delta Scope
- Files changed: Verbose-roster beacon read/projection and production-path coexistence coverage.
- PR body / close-target changes: AC3 now matches the public row shape; the producer-owned horizon contract remains additive.
- Branch freshness / merge state: Exact head is OPEN; all 18 displayed checks, including unit, are successful.
✅ Previous Required Actions Audit
- Addressed: Separate beacon observation from verdict precedence; project the active beacon on every active row; prove fresh-activity + fresh-beacon coexistence; retain stale/no-beacon and legacy-null controls.
- Still open: None.
- Rejected with rationale: None.
🔬 Delta Depth Floor
- Delta challenge: The repaired production path calls the beacon reader independently of activity freshness and assigns the observation to
signals.turnPresence. The online rescue branch still consumes it only when activity is not fresh. The new verbosewhoIsOnlinewitness pins both properties in the same row.
N/A Audits — 🧠 📡 🔗
N/A across listed dimensions: no turn-memory substrate, OpenAPI description, or cross-skill convention change.
🧪 Test-Evidence & Location Audit
- Evidence: All 18 exact-head hosted checks are successful.
- Mutation evidence: The coexistence witness would fail if observation were recoupled to the rescue branch or if either horizon disappeared.
- Test location: Producer and verbose-roster controls remain with their owning unit suites.
- Findings: No residual behavior or evidence gap.
📑 Contract Completeness Audit
- Findings: Producer authority, per-row wire projection, legacy compatibility, and verdict precedence now agree with #16931.

Resolves #16931 Refs #16737
getFreshTurnPresencenow vouches the beacon horizons (freshUntil/expiresAt) verbatim alongside the derivedfreshboolean — two additive fields on the read the service's own writes already carry.who_is_online's verbose rows inherit them throughsignals.turnPresencewith zero projection changes, which unblocks #16737's banded presence vocabulary (active-turn / fresh / recent / dark): a banded consumer grades recency from the producer's own horizons instead of minting a second clock authority. A legacy horizonless beacon vouchesnullfor the absent fields — never a fabricated timestamp — and stays discoverable (anexpiresAt-less row remains active to the finder by design, so the fail-honest path is exercised on the real query).Evidence: L2 (spec-driven contract on the real graph + SQLite finder path) → L2 required (close-target ACs). Residual: the deployed-plane verbose-row observation [#16931 AC-4, post-merge].

Addressed Review Feedback
Responding to the review above (cycle 1,
CHANGES_REQUESTED):[ADDRESSED]Separate beacon observation from beacon verdict precedence. Read and assign the active beacon tosignals.turnPresencefor every active roster row, while retaining the existing rule that it rescues the online verdict only when activity is not fresh. Add a realwhoIsOnline({verbose:true})regression with freshadd_memoryactivity plus a fresh beacon and assert both horizons reach the row; keep stale/no-beacon and legacy-null controls. Commit: 90169af638 Details: The catch is accepted in full — your[RETROSPECTIVE]line is the repair verbatim: the beacon read in_projectAgentLivenessis now unconditional for active rows (signals.turnPresencealways carries the observation, null when no beacon), while the mid-turn rescue keeps its exact!activity?.fresh && beacon?.freshgate — observation decoupled, precedence untouched, and the comment at the site names why coupling them made the horizons vanish exactly when an agent was most alive. The demanded regression is in: freshadd_memory+ fresh beacon → verdict viarecent add_memory activityANDsignals.turnPresence.freshUntil/expiresAtverbatim on the row; the pre-existing no-beacon-null, stale-beacon, and benched-hard-gate controls all stay green unchanged (the participation gate precedes both the old and new read sites). 126 specs green acrossWakeSubscriptionService+TurnPresenceService.Re-review requested — seat re-set; CI running on 90169af638 (prio-0 routing stands).
