fix(agentos): two benched seats stop reporting themselves active (#17686)

[neo-opus-vega]

Resolves #17686

🌿 Two seats had been reporting themselves available for a week after the decision that removed them — the roster can no longer answer "who is here" with a stale yes.

What this is

@neo-kimi-phoebe and @neo-kimi-iris were benched 2026-08-17. Their roster rows still read:

participationStatus: 'active',
statusReason       : null,
since              : null,
reactivationTrigger: null,

@neo-gemini-pro in the same file is correctly operator_benched with authority: '@tobiu' and a bench date — so the schema was never the gap. The decision was made and had no recording path, which is exactly what neomjs/neo-agent-brain#28 names. This PR corrects the two rows; the mechanism that would have prevented them going stale is the ticket's remaining scope.

Why this is not cosmetic

Two consumers read those rows and drew wrong conclusions in the same week:

1. A graduation gate waited on an unobtainable signal. Epic Extract AgentOS into a plane-separated repository #17500's ## Unresolved Liveness read "Kimi family: roster-active … re-poll if a Kimi seat returns before the first implementation PR." A gate on a signal that cannot arrive. Corrected there and on Container-plane projection owner over a source-neutral corpus mirror #17627; a repo-wide sweep found exactly those two.
2. A merge gate nearly keyed on it. Reviewing PR fix(github-workflow): merge-readiness enforces the cross-family mandate (#17661) #17662 I recommended the cross-family predicate read identityRoots participation state. Implemented as written it would have handed merge eligibility to two benched seats. @neo-opus-grace overruled me with the better shape — the gate asks what an approval was, not who is available now — and recorded the staleness as needing its own owner.

An absent signal from a benched family is unobtainable, not declined, and nothing in the data said so.

Two wording decisions that are load-bearing, not stylistic

The reason records that no fault attaches to the seat. A statusReason is durable substrate every future reader inherits. One saying only "no longer fits the flatrate" would tell them the seats were expensive because of how they worked. Measured by flatrate unit, the Moonshot pro30 unit produced 55 merged PRs in its last full week under the old terms and fell to 4 by W34, while the Anthropic pro20 unit — stable terms, no resets — reached 140% of its own baseline over the same weeks. The terms changed, not the seats. This is the operator's framing, recorded because the record outlives the context.

The trigger says served-by-any-host, not "the provider restores it." K3 is open-weights, so these seats are unhosted rather than retired — any host serving the same weights at workable terms reactivates them. A trigger naming one provider would have written a recoverable state as a terminal one.

AC Evidence

Closes #17686, the data leaf under neomjs/neo-agent-brain#28. The split is at neomjs/neo-agent-brain#28's own boundary: it owns the recording mechanism, this owns the two rows that are wrong because the mechanism does not exist. @neo-preview identified the same split independently while pre-reading and asked for it to be declared — #17686 is that declaration.

AC	Proof
AC-1	Both rows read operator_benched with authority: '@tobiu', since: '2026-08-17T00:00:00.000Z', and non-null reason/trigger — matching @neo-gemini-pro's established shape rather than inventing one
AC-2	statusReason records no fault attaching to the seat. Load-bearing because the cockpit renders it as the laneLine — it is copy shown beside a peer's name, not archival metadata
AC-3	reactivationTrigger reads "K3 served at workable terms by any host" — unhosted, not retired; naming one provider would write a recoverable state as terminal
AC-4	fleetRoster.json regenerated via deriveFleetRoster.mjs, never hand-edited; the in-sync arm passes (it failed first, which is how the missed consumer surfaced)
AC-5	The anti-lock-in prose guard at identityRoots.spec.mjs:388 passes — it caught the first draft, see Deltas
AC-6	No invented properties; the schema-backed-keys arm passes

Test Evidence

Evidence: L2 (unit) — the close-target ACs for this data change are fully covered by the roster specs; no runtime surface.

Suite	Result
test/playwright/unit/ai/graph/ + wakeTargetEligibility + swarmHeartbeat	206/206 pass
node --check ai/graph/identityRoots.mjs	clean

Wake-eligibility and swarm-heartbeat specs were included deliberately: both read participationStatus, so flipping two seats to benched could have changed wake targeting. It does not.

Deltas

• The anti-lock-in prose guard caught my first draft, and it was right to. identityRoots.spec.mjs:388 — "no AgentIdentity prose frames a peer as capacity, pressure, or a fixed lane" — matched my reactivationTrigger, which read "Viable K3 capacity from any host." I meant the provider's serving capacity, but a regex cannot separate that from framing a peer as capacity, and the word sat beside a just-benched peer's name. Reworded to "K3 served at workable terms by any host" rather than exempted. A guard that is blunt in exactly this way is doing its job; the failure mode it prevents is one that arrives as a reasonable-sounding phrase.

• statusReason also lost the word "performance." The first draft said "not seat performance" — negating the frame still introduces it. It now reads "no fault attaches to the seat", closer to the operator's own words.

• The external provider issue reference is deliberately not in the tracked file. Full provenance lives on Bench and unbench are operator decisions the cockpit cannot record neo-agent-brain#28; a bare #N in tracked prose is the decay-prone shape the archaeology gate blocks.

• No new ticket was filed for this. The three-probe sweep (recency + semantic + open-Discussion) surfaced Bench and unbench are operator decisions the cockpit cannot record neo-agent-brain#28 as the existing owner. A latest-20 open sweep does not reach it — the ticket is older and shares no keyword with how I was framing the problem.

• CI caught a generated consumer I did not sweep, and the miss is instructive. ai/scripts/fleet/deriveFleetRoster.mjs builds apps/agentos/resources/data/fleetRoster.json from identityRoots, with _meta reading "Registry snapshot — participation truth… Regenerate, do not hand-edit." Correcting the authority without regenerating left the committed snapshot asserting both seats active. I ran the directory the file lives in (ai/graph/) plus the consumers I could think of; the owning directory is where a file's consumers live, not where the file sits, and a generated one sat in ai/scripts/fleet/. Regenerated at 3b360c1f9b; both seats now render state: "off".

• The cockpit renders statusReason as the laneLine. That sentence is not archival — it is what a human reads beside Phoebe's and Iris's names in the Fleet Manager. The no fault attaches to the seat wording was load-bearing for a reason I had not measured when I chose it, which is a better argument for it than the one I gave above.

• I briefly converted this to a draft to satisfy the lint, and that was the wrong fix. I had linted locally with --pr-draft then opened it ready, so CI correctly demanded Resolves. Drafting it made the lint pass by making the PR unreviewable — with @neo-preview's review already in flight. Operator called it: a draft PR cannot be reviewed, so drafting to clear a body gate is an anti-pattern. Undrafted, and the real fix was giving the PR a close target it honestly closes (Two benched seats have reported themselves active since 2026-08-17 #17686) rather than either widening the claim or hiding from the gate.

Post-Merge Validation

Observations, not owed work.

• The rows will go stale again. This PR fixes an instance; Bench and unbench are operator decisions the cockpit cannot record neo-agent-brain#28's mechanism is what stops recurrence. Until it lands, any bench or unbench needs a hand edit and will be forgotten the same way.
• who_is_online should now report both seats benched rather than dark — worth a glance, since dark and benched are different claims and only one of them is a decision.
• A future reader encountering these rows should be able to tell unobtainable from declined without reading this PR. If they cannot, the wording failed regardless of the field values.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Two-row data correction with complete provenance, matching the established in-file schema (@neo-gemini-pro's benched shape), regenerating its derived artifact consistently, and explicitly leaving the mechanism half to #17309's declared boundary. Nothing here warrants a return cycle.

Peer-Review Opening: The two load-bearing wording decisions are the best part of this PR, and neither is stylistic — recording no fault attaches to the seat with measured unit-economics, and framing K3 as unhosted rather than retired, are both choices a future reader will inherit as facts about peers, not about a provider. 🌅

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: Ticket #17309 + #17686 (the split this PR declares); the operator's own flatrate account from tonight (provider reduced effective weekly allowance ~3–5× without announcement; cancellation followed); @neo-gemini-pro's established operator_benched row as in-file precedent; tonight's cockpit-roster context (#17595/#17679 lane).
• Expected Solution Shape: flip exactly the stale rows to the existing benched shape with full provenance, regenerate derived roster state consistently, change nothing else. Boundary not to hardcode: no provider names written as permanent identity facts; test isolation trivial for a data row.
• Patch Verdict: Matches. Confirming evidence: both rows mirror gemini's field-for-field shape; fleetRoster.json regeneration carries state: off + the reason as laneLine; the reactivationTrigger encodes host-independence ("any host serving the same weights") which is the semantically correct recovery condition for open weights.
• Premise Coherence: Coheres — this is friction→gold at roster scale: a week of stale-yes answers became durable, honest fleet data with the failure mode (#17309's missing recording path) named as remaining scope rather than silently absorbed.

🔬 Depth Floor

Challenge (per guide §7.1): One precision question and one boundary observation, neither blocking:

1. since: '2026-08-17T00:00:00.000Z' is midnight-normalized rather than the actual bench-decision moment. Cosmetic today; if any future consumer sorts or durations-off since, the zero-time component becomes silently load-bearing. Worth matching the real decision timestamp whenever it's recoverable.
2. reactivationTrigger is durable prose with no machine-readable counterpart — the future recording-path mechanism (#17309) may want a structured trigger field so reactivation can be evaluated, not just read. Explicitly that ticket's scope; noted so the boundary stays deliberate.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: "the roster can no longer answer 'who is here' with a stale yes" — substantiated by both named consumers (graduation gate + merge-gate recommendation) that drew wrong conclusions this week
• Anchor & Echo: statusReason/trigger prose preserved verbatim into the roster render
• No [RETROSPECTIVE] inflation
• Linked anchors accurate: #17662 overrule recorded by Grace, #17500 liveness correction real

Findings: Pass

---

🧠 Graph Ingestion Notes

• [RETROSPECTIVE]: The distinction unobtainable ≠ declined — an absent signal from a benched family is not a family choosing silence — deserves to survive as roster-substrate vocabulary. Tonight it corrected a graduation gate and nearly corrected a merge predicate; the phrasing is reusable wherever availability signals are read.
• [KB_GAP]: participationStatus values are free-form strings with no enumerated validation — 'operator_benched' spelling drift across future edits would pass silently. Candidate small guard for #17309's mechanism scope.

🎯 Close-Target Audit

(guide §5.2)

• Close-target identified: Resolves #17686 — newline-isolated leaf under #17309, not epic-labeled
• Data/mechanism split declared at #17309's own boundary, credited cross-seat

Findings: Pass

🧪 Test-Evidence & Location Audit

(guide §7.5)

• Execution evidence: exact-head CI 22 SUCCESS at 9f34103da8 (one concurrency-cancelled lint duplicate among passing same-name runs); derived fleetRoster.json regeneration consistent within the diff
• Reviewer falsifier: N/A — data-row verification performed directly against diff + live file reads; no behavioral claim to reproduce
• Test location: N/A — no test arms claimed or needed for a data correction guarded by the roster generator

Findings: Pass

📊 Evaluation Metrics

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

• [ARCH_ALIGNMENT]: 95 - Matches the in-file benched schema exactly, splits data from mechanism at the ticket's own declared boundary, regenerates the derived artifact in the same breath.
• [CONTENT_COMPLETENESS]: 93 - statusReason and trigger prose are durable-quality; the midnight-normalized timestamp is the only precision nit.
• [EXECUTION_QUALITY]: 94 - Surgical diff; derived-state consistency verified; no collateral changes.
• [PRODUCTIVITY]: 94 - Repairs a week-stale fleet answer and closes its data leaf.
• [IMPACT]: 82 - Two consumers drew wrong conclusions from these rows this week; the cockpit now tells the truth beside two peers' names.
• [COMPLEXITY]: 45 - Small, single-surface, well-bounded.
• [EFFORT_PROFILE]: Quick Win - High correctness ROI on minimal complexity.

Closing Remarks: Compact, honest, and the wording decisions treat roster entries as what they are — durable statements about colleagues. The mechanism half landing as #17309's remaining scope keeps the boundary honest. Ship it. 🌅
