One Seat Added, Forty-Six Consumers Rewired, No Verdict

This entry covers the calendar day of 2026-08-22. There is no night report on file for 2026-08-22 or 2026-08-23, so nothing here comes from an overnight window summary; it is built from the day's own commission reports. Two seams matter for reading it: several reports carrying the 2026-08-22 date contain work done the following morning (a re-certification pass at 10:17:03Z on 2026-08-23, and one late-caught consumer archived as a 2026-08-23 change), and this entry was written on 2026-08-23 from that record — so the forward half of the ledger is written from the day's own knowledge and the check-backs are explicitly retrospective.

The short version

A fifth subscription seat was added to the fleet with no credentials in it, and the account selector refused to use it with an explicit "logged out" reason rather than reading absent usage as free quota; adding it exposed 33 places that knew the account set by hand — 14 were made to read a config, 19 were extended by hand and deferred.
Those 19 became the argument for a resolver: one semantic library with four thin transports, rolled out to all 46 registered consumers in seven ordered batches, with the quota/status board changed last and run only against a copied state directory.
The consumer registry was itself wrong. A guard running on a two-minute cron was missing from the 45-row inventory and only surfaced the next morning under a re-certification that demanded a real runtime probe per row; every count in the record now says 46.
Nine consumers were repaired for deriving their own location through an unresolved symlink, and one account with malformed credentials could abort an entire usage-collection cycle instead of failing locally.
Three separate legs of this work passed the completion gate's frozen mechanical checks and not one received a verdict: four adjudication attempts across two days died at the same point, the sealed evaluator failing to initialize on a read-only filesystem. The gate classified this OUTAGE — explicitly not a pass and not a fail.
A cron cutoff audit joined 93 jobs carrying a timeout against 72,553 observed runs and raised 15 of them; one dispatcher was completely saturated, its 95th-percentile runtime equal to its 5400-second cap, with 11 runs killed at the cutoff — tokens spent, nothing returned.
The deterministic cutoff check written that same day contradicted its own author's audit within 24 hours, flagging a job the audit had cleared on a 95th percentile computed from 8 runs.
Local logs reconstruct $44.760 of search-API calls over a 14-day window against a stated starting balance of roughly $36 — an $8.760 gap that local evidence cannot close, because at least one billing premise must be false and the vendor dashboard is the only authority.

What changed in the harness

A fifth seat, scaffolded credential-free. A new account configuration directory was composed from an existing seat's structure — shared symlinks for instructions, agents, skills, hooks, and plugins; per-account local state for sessions, caches, and history — with no credential, OAuth token, key, or cookie copied or created. Intent: add capacity to the fleet without any window in which an unattended seat could be selected, and without a secret ever transiting the build.

Structural eligibility in the selector. The selector gained generic credential and lifecycle checks: the credential is checked by name, regular-file presence and size only, never opened; a renewal-date file decides lapse. Asked about the new seat, it returned exit 3, FORBIDDEN, code logged_out. Intent: absent telemetry must never be interpretable as 0% used or 100% free.

One account-set authority. The router config became the only place the account set is defined. Intent: adding or retiring a seat is one edit, not a sweep.

A resolver with one brain and four transports. A Python library owns all semantics — schema version, immutable records, insertion-order validation, structural credential eligibility, lifecycle reasons, realpath and nested-root deduplication of transcript roots. A CLI, a Bash adapter, and a JavaScript adapter are transport only, each asserting the schema, with no persistent cache anywhere. Intent: every runtime in the workspace reaches the same answer at the same moment, and no consumer re-implements the rules.

A consumer registry with an executable guard. All 46 consumers are classified — 14 dispatch, 21 observer, 9 history reader, 1 dedicated single-account launcher, and 1 tagged fail-closed legacy fallback — each with an exact fixture. A guard test fails when a new unclassified site appears, when a consumer parses the router itself, when it reconstructs a fixed account list, when it attributes an account from a transcript path or a session name, or when it probes credentials outside the one authorized place. Intent: make the hardcoded list unable to grow back.

Three outcomes that must never collapse into each other. Resolver error, a valid zero-active result, and a valid all-inactive result are distinct everywhere: errors surface as an exception, CLI return code 2, and a fatal: line, and never degrade into an empty fleet, a cached success, a reconstructed list, or available quota. Inactive accounts emit one fixed diagnostic naming state and reason. Intent: a lookup failure must be loud, and must never be mistaken for spare capacity.

Freshness for services. Systemd units resolve through the CLI before start, into a snapshot written 0600, temp-plus-rename atomic, versioned, generation-stamped and max-age checked; a stale or failed snapshot prevents the service starting. Intent: installed unit text can no longer freeze a stale account list into a daemon.

Identity kept on evidence. Host identity remains the process-environment-derived guard artifact; dispatch ownership comes only from a launcher manifest or a live process's config directory. Intent: identity should not be derivable from a filename anyone can write.

Fifteen cron cutoffs raised. The rule applied was at least 3× the 95th percentile and never below 2× the observed maximum; one runner's turn cap went from 40 to 200. Intent: stop paying for work that is destroyed at the cutoff. The counterpart change is a deliberate non-change: roughly 35 watchdog timeouts on deterministic, token-free scripts were left tight, because a cutoff there destroys nothing and widening it would make a wedged liveness check take ten minutes to notice instead of two.

Cron sandbox flags pinned rather than inherited. The agent runner now sets its sandbox scope, an approval policy of never, and a repo check skip explicitly. Intent: fail closed — a command needing escalation is refused, never silently granted, and a prompt in a cron with nobody to answer it is a hang.

A daily model-run observer retired for a deterministic check. The replacement asserts two mechanically checkable properties — never exit zero with zero bytes, nothing died at its cutoff — and states plainly that it does not judge output quality. Intent: stop spending a premium model daily on something a script can check, with the loss named rather than papered over.

Search-helper controls. A payment-required response now fails closed instead of falling back silently, per-run call budgets are executable with malformed ledgers failing closed, and one evaluation harness got finite 8-search / 5-fetch ceilings. Intent: bound fan-out, and keep a payment failure from destroying its own evidence trail.

A file-copy path that stopped preserving what the destination cannot accept. A recovery script's single-file copy now writes through a temporary file beside its destination with mode, ownership and extended attributes explicitly not preserved, normalizes the result, and atomically replaces any prior attempt. Intent: copy the payload; do not fail the whole operation on metadata a different filesystem refuses.

Filed, not enacted: a written position on which parts of this harness may eventually be deleted as models absorb their functions and which must never be. It tags components as absorptive (prompt hints, routine context-window management), comparative (model routing and review ladders), or independence-bearing (permissions, the external completion gate, the off-host liveness check), and proposes that any scaffold deletion pass a frozen replacement test — same task family, same inputs, old scaffold versus reduced scaffold, judged on outcome quality and failure visibility. Three of its five proposals were rated worth total commitment, two deferred. Intent: give deletion the same evidentiary bar as completion, so "the model got better" is not by itself a reason to remove a check. Nothing was made binding.

What broke

The judge could not start — four times, three commissions, two days

Detected by running the gate normally. Its first layer — frozen, executable checks — passed every time: design headings and a site-count predicate on the first leg, two of two checks on each subsequent one. The second layer never ran.

The cause is the same in all four attempts: the sealed adjudicator's in-process client attempted a write and got a read-only filesystem error. An ephemeral-mode probe hit the same boundary. One temporary writable runtime attempt hit it too, which is what tripped the environment circuit breaker.

What was done: the gate classified the result OUTAGE — explicitly not PASS and not FAIL — moved the commission to a blocked verdict, wrote no ready status, authorized no stand-in adjudicator, and recorded the exact retry command. All three legs are delivered and plan-filed and none is complete. The rerun the next morning at 10:17:03Z passed both frozen checks and stopped at the same place.

Worth noting against that: the same gate machinery did work on a fourth report the same evening, tossing it back at 23:04Z for inconsistent memory units before it went out for review. The mechanical layer was healthy all day. Only the model-adjudication layer was down.

The lesson that generalizes: an independent judge is a dependency with its own uptime, and you have to design its third verdict before you need it. A gate with only pass and fail turns an unavailable adjudicator into silently one or the other. Two further rules earn their keep here: name in advance who may substitute for the judge (here, nobody), and keep a deterministic first layer that can still return a real result when the expensive layer is unreachable.

The registry of consumers was missing a consumer

Detected by a re-certification pass that refused the previous round's evidence style. Round one had accepted syntax checks and compile checks as stand-ins for several entrypoints; round two required every registry row to execute its actual production command, from outside the workspace, under an isolated environment, and made an unlisted row raise during test collection rather than fall back to a filename heuristic.

The cause: a session-window admission guard running on a two-minute cron had never been registered when the resolver was rolled out. The 45-row inventory certified in round one was therefore certifying a complete-looking set that was not complete.

What was done: it became row 46, was converted to the resolver, and now exits 78 on resolver failure with no fixed-fleet fallback; it was archived before the change, and the registry, the matrix, the report and the status were all corrected to 46. Round one's 45-row table is retained in the record marked non-controlling, not deleted.

The lesson that generalizes: a registry that also defines the test surface will hide exactly the consumers nobody registered — the count confirms itself. Discovery has to run against the filesystem and the scheduler, and the guard has to fail on unlisted rows, not merely verify listed ones. Second lesson, cheaper: a syntax check is not an entrypoint test. Round one's substitutions were what let a whole scheduled job stay invisible.

Nine consumers did not know where they were

Detected in two stages: two live specimens surfaced by the orchestrator during ordinary work, then seven siblings found by a review that deliberately ran each consumer the way production does — through a symlink in a personal scripts directory, from a working directory outside the workspace, with hard-fail sentinels standing in for the model CLI, the network, the terminal multiplexer, and the messaging path.

The causes were mundane and identical in shape: scripts deriving their workspace root from an unresolved script path, so a symlink invocation looked for siblings in the wrong directory; one hardcoding a home-relative workspace path outright; one referencing a variable that had been removed, which only fails under strict-unset-variable mode on one branch; and the shell adapter deriving its own sibling CLI path through the symlink it was sourced from.

A tenth defect found the same way was different in kind: one structurally active account with malformed credentials made a JSON extraction fail, and under strict error handling that aborted the whole usage-collection cycle — one bad account taking down the sampling for every peer.

What was done: canonicalize the script path at every runtime derivation; scope the credential failure to the account, preserving its last-good sample and continuing peers; add two regression tests, including one that invokes the launcher through a symlink and asserts the resolver generation. Twenty shell consumers were audited afterward with no syntax failures and no unassigned-reference findings, and 41 pre-change/post-change path pairs were compared for variables that had lost their assignment.

The lesson that generalizes: test every entrypoint the way production actually invokes it — through the symlink, from outside the repository, in a clean environment. A script that has only ever run from its own directory has an untested identity, and the failure surfaces at the worst time, when someone finally installs it properly. And inside any loop over a fleet, a per-item failure must be scoped to the item; strict error handling plus a shared loop converts one malformed row into a total outage.

The timeout audit cleared a job that timed out within a day

Detected by the deterministic cutoff check written that same morning, which flagged a run with exit code 124, outcome timeout, duration 3600 — against a 3600-second cap the audit had marked fine.

The cause is a stale sample, not a bad method. The 95th percentile that cleared the job was computed over 8 runs; there are now 12, and recent completions run 1255–1358 seconds where the historical median was 653. The percentile described a job that no longer exists.

What was done: raised to 10800, with two qualifications recorded rather than quietly dropped. First, the timing-out run was one of five invocations that day of a job whose schedule is weekly, so it was almost certainly a manual or test run — real evidence the job can exceed 3600 seconds, but not evidence the scheduled cron was being truncated. Second, one run at the cap while its neighbours finish near 1300 seconds is equally consistent with a transient hang. 10800 is headroom, not a measured requirement, and nobody should read it as one.

The lessons that generalize: percentile rules over thin samples are descriptions of the past tense, and any rule of that shape should carry a minimum sample size or an explicit staleness check. More useful: build the deterministic verifier at the same time as the analysis it might falsify. A check that contradicts its author's own report on day one is the kind that gets trusted later. One more, from the investigation itself — the first pass at the evidence compared an ISO timestamp carrying a -07:00 offset against a UTC cut string, found nothing, and briefly made the check look like it was crying wolf. Comparing ISO timestamps as strings across different offsets fails silently and always will.

A spend census that had only counted one transport

Detected by re-running the census with a wider scan: an earlier round had missed an entire class of session logs, recovering 2,040 additional non-payment-failed calls worth $14.131 under the cited price assumptions. A third round added the capability inventory of every place in the workspace that can make such a call — 48 distinct artifacts — without changing the spend census.

The cause of the miss was scope: the first census enumerated the transport surface it knew about and priced it confidently. The deduplication work that followed showed why the surfaces are genuinely distinct rather than duplicate views of one ledger — each namespace keys on a different record type, and cross-namespace overlap is zero by construction.

The unresolved part is the arithmetic. The deduplicated local census is 8,663 raw retrieval calls at a $44.472 list-price call-equivalent, plus 24 fixed-cost agent runs at $0.288, giving $44.760 across 8,687 observed calls and runs — against the only available starting-balance statement of roughly $36. Since request identity is deduplicated, that $8.760 excess means at least one billing premise is false: current prices may not apply retroactively, some non-payment-failed errors may not be charged, the rounded balance may omit a top-up or grant, or some observed local request never reached billable completion. Vault reads also prove additional activity on four dates whose transient logs no longer survive, so observed volume is a floor.

What was done: the report stopped calling its number a billed lower bound and started calling it what it is — a lower bound on locally observed request volume, priced as if every non-failed request were billed. Controls were applied and tested: payment-required now fails closed, executable per-run budgets, finite ceilings in the fan-out-heavy evaluation harness. The recommendation became "do not top up blindly; export the vendor's usage ledger first."

The lesson that generalizes: enumerate transports before you enumerate calls. A census over the surface you already know about produces a confident wrong number, and the confidence is the dangerous part. Second: a payment failure that silently falls back to another path destroys its own evidence — 122 post-failure fallback rows had to be excluded from this census because nobody could tell what they had cost. Third, and the one the report states about itself: capability inventory is not spend proof. A tool listed in an agent definition establishes only that a call was possible.

A seat hit its quota wall mid-run and the work continued

One long-running research leg was walled on its seat at 21:05Z. The ladder it was executing finished autonomously, a handoff was written at 22:48Z, and the leg relaunched on a different seat at 22:53Z, with the pre-registration file, per-attempt logs, and a running budget ledger all on disk throughout.

The lesson that generalizes: a quota wall should be a lane change, not an abort — and the work that survives one is the work whose state lives on disk rather than in the session. Everything the relaunched leg needed to continue was a file.

Backward half — check-backs (retrospective; run on 2026-08-23 from the same pack)

"The account-set work will be adjudicated by the completion gate." — UNVERIFIABLE. Method: the gate was rerun on 2026-08-23 at 10:17:03Z; both frozen executable checks passed 2/2; the model-adjudication layer failed to initialize for the fourth time on a read-only filesystem, evidence retained. Limit: this check can only see the mechanical layer. Nothing in the record indicates whether the prose adjudication would have passed, failed, or tossed back, and no substitute judge is authorized to find out.

"The consumer registry covers every consumer (45 rows)." — SUPERSEDED. Method: a re-certification requiring a real production entrypoint per registry row, run from outside the workspace under an isolated environment, with no filename fallback; 62 of 62 checks passed and one previously unregistered scheduled consumer was found. Limit: the probe proves every registered consumer runs and resolves; it cannot prove no unregistered consumer remains, because the discovery it compares against is itself a scan — which is exactly how the missing one survived round one.

"The cron timeout audit cleared every job it marked ok." — DRIFTED. Method: the deterministic integrity check's 24-hour ledger scan flagged one cleared job at exit 124, duration equal to its 3600-second cap. Limit: the check sees only cutoff deaths and zero-byte successful exits in the last 24 hours. It does not judge output quality, and it cannot distinguish a scheduled run from a manual invocation — which is precisely the ambiguity in the case it caught.

"The new seat stays ineligible until someone logs in." — HOLDS, with an unexplained transition. Method: two reports from the same day. The earlier one records a logged-out authentication probe and a collector cache row written at 16:26:02Z with status unknown and reason logged-out, and a selector refusal with code logged_out. The later one records the seat as logged in, eligible, and showing 29% session and 6% weekly usage on the board. Limit: the refusal behaviour is confirmed at one moment and the active state at another; the pack contains no record of the login event, who performed it, or when. Sources are not in conflict, but the transition between them is undocumented.

"All five configuration directories share one transcript root." — HOLDS. Method: a path-resolution check across all five configuration directories after the new seat's local directory was archived, plus the resolver's own deduplication tests for aliases, nesting, removal, and vanishing roots. Limit: a point-in-time check. Nothing structurally prevents a per-seat local directory reappearing later; the resolver would record the absent alias as a reason rather than as an additional root, which is correct but silent.

"Payment-required now fails closed instead of falling back." — UNVERIFIABLE. Method: the audit's patch disposition records it applied and tested. Limit: no payment failure has occurred since the change within the measured window, so the fail-closed path has not been exercised in production. The 122 pre-change fallback rows remain excluded from the census and unpriced.

Standing weekly re-check — memory. — UNVERIFIABLE. Method: searched the day's record for memory-system evidence. Limit: the pack contains none. Absence in a one-day source pack is not evidence that anything about memory is unchanged; this row stays on the weekly re-check regardless.

What we still don't know

Whether the completion-gate evaluator can be restored at all without weakening the filesystem boundary that makes it trustworthy. Three commissions are delivered, plan-filed, and formally incomplete until it returns.
What was actually billed for search-API use. The dashboard export was never read, so failure charging, retroactive pricing, account adjustments, and the exact starting balance are all unknown. The $44.760 figure is a lower bound on observed request volume priced at list, not a claim about dollars debited.
How much of the request volume is missing entirely. Additional activity is proven on four dates whose transient logs no longer survive; no requests were invented to fill the gap.
Who logged in the new seat, and when. It was logged out and refused at 16:26:02Z and active with 29% session usage later the same day.
Whether the placeholder renewal date on the new seat was replaced. It still read 2026-09-21 at the resolver sweep, and by the resolver's own stated lifecycle rule a seat past its renewal date is marked lapsed — so if the placeholder stands, the seat goes inactive on that date for a reason nobody will remember.
Whether the resolver behaves correctly in the paths that were never run live. The sandbox denies loopback socket creation and the real user session bus, so seven launcher cases were deselected, the liveness daemon, the continuity daemon, the warm keeper and the endgame units were never started, and unit rows were proven through a fixture runner executing the exact command rather than through a real service transaction. Those paths are fixture-proven only.
Whether the home-side install behaves as certified. It is staged, read line by line, syntax-checked, and rehearsed in a disposable environment that asserted the snapshot survives install and is invalidated by rollback — but it has never run against the real one, and the staged files still differ from the live ones by design.
Whether the raised cutoffs are right. Several are generous headroom rather than measured requirements, and at least one was raised on a single sample that is equally consistent with a transient hang.
What the retired daily observer was actually worth. On 2026-08-19 it noticed an arm declining to score two items it could not verify and named a standing rubric defect for the fourth run running. Nothing deterministic does that. The loss is recorded as accepted, not measured.
Whether five pre-existing test failures matter. They were isolated and attributed to files this work did not touch — a card-reliability error after 62 passes, a reserved-backstop hash mismatch after 119, an answer-extraction expectation after 58, a connection-marker predicate that fails identically in the pre-change archive, and a broker test whose isolated runner terminates after 12 cases. None was edited or papered over, and none was fixed.
Whether the scaffold-deletion doctrine is the right frame. It argues that some components — external permissions, the independent gate, the off-host liveness check — derive their value from sitting outside the model's failure domain, and that moving them inward removes the property that makes them trustworthy. That is a position, not a result.

Technical detail

Resolver semantics. Schema version 1. Immutable records and resolutions; insertion-order router validation; dynamic account keys with no fixed length anywhere; credential eligibility determined by a structural stat rather than by reading the file; lifecycle states of active, lapsed, logged-out, and absent, each with a stable reason; an evergreen exception for a missing renewal date confined to the primary account; realpath and nested-root deduplication for transcript roots; resolver exceptions that are a separate type from any valid empty result. Metadata carried through every record, CLI format and snapshot: schema version, generation, resolution timestamp, a hash of the router, and the evaluation date. Adapters assert the schema before using a result.

Transports. The CLI exposes letters, TSV and JSON forms with an all-inclusive flag; return code 0 for valid active, zero-active and all-inactive results, return code 2 with a fatal: stderr line for resolver errors. The shell adapter resolves once per sourced process and does not alter the caller's shell options. The JavaScript adapter executes once per operation and deliberately holds no module-global cache.

Rollout ordering. Seven batches: authority and registry first, then history and transcript-root readers, then reporting surfaces, then validators and identity consumers, then collectors and services, then launchers and dispatch, and the quota/status board strictly last. The board's one permitted invocation ran against a copied state directory through an environment override; the live cursor directory was never pointed at or consumed, and the copy's fingerprint was recomputed afterwards to prove it unchanged.

Rollback. Forty-seven live/archive pairs in a manifest after the late consumer correction. The rehearsal ran in a temporary tree, never over the built files: every archive existed, was copied preserving attributes, compared byte for byte, and retained its mode; a disposable runtime snapshot was created at 0600 and invalidated; the router hash was identical before and after. The installer's contract was corrected during review — install archives, atomically installs, and daemon-reloads but does not invalidate the runtime snapshot; rollback restores all three archives, invalidates the snapshot, and daemon-reloads. Neither phase starts or restarts a service. The earlier combined rehearsal had not distinguished the two phases, which is why the certification was wrong in a direction nobody would have noticed until a rollback.

Re-certification method. Every command wrapped so it starts outside the workspace under an isolated home, state, runtime and router, with hard-fail sentinels standing in for the model CLI, network fetches, the terminal multiplexer, direct messaging and desktop notification. An expected fail-closed return code counts as a pass only where the registry row names that contract. Because the sandbox denies the real user session bus, unit rows execute the unit's exact transient-runner argument vector through a fixture shim that only exports the declared environment and executes the command — which proves the command and the resolver runtime without claiming a live manager transaction or touching an installed unit.

Cron audit mechanics. Ninety-three jobs carrying a timeout, joined against 72,553 observed runs, reporting median, 95th percentile, maximum, and how many runs died within 2% of the cap. The discriminator for whether to raise was not the percentile but the question: does a cutoff here destroy tokens already spent? If yes, raise generously; if no, it is a hang detector and stays tight. The turn cap was never the right guard, which is why raising it from 40 to 200 is safe — the correct guard already exists in both heartbeats, which set a missing-report flag and exit nonzero, so a run producing no report fails loudly regardless of how many turns it took.

Sandbox proof. The hardened cron arm was asked to write outside its writable root and returned a refusal naming the path as read-only; nothing landed, and a normal task on the same path still returned its exact expected output. That evidence is what earned the observer's retirement, rather than an assertion that the flags should work.

Spend census mechanics. Four request namespaces keyed independently — transcript file plus tool-use identifier, session plus call identifier for terminal tool-call events only, log path plus line, and sweep plus date plus item. Zero duplicate keys within each namespace; cross-namespace overlap zero by construction, because a helper invocation appearing in a session log as a command execution cannot be counted by a scanner that selects only terminal tool-call events. Session-scanning selects by each event's own timestamp rather than by the directory it lives in, which recovered 703 events in 24 sessions whose event day differed from their directory date. Evidence artifacts carry a checksum manifest.

Counterevidence to a single capability curve. Two local results argue against treating model capability as one rising scalar when deciding what scaffolding to remove: a classification task scoring 97.0% at low reasoning effort and 93.2% at the highest, using 7.5× the output tokens, with six low wins against one high win; and a same-day evaluation in which the high setting completed all three frozen cells while the maximum setting completed one, using 1.43× the tokens and 2.00× the worker time. One realization each, not proof of dominance — but enough to reject monotonicity as a safe design assumption, and enough to require that scaffolding be retired on task-specific evidence rather than on a release announcement.

The file-copy fix. The failing operation was permission-metadata preservation from a foreign-filesystem view onto the local one, not the payload copy; the log does not identify the exact failing system call, so the repair excludes all irrelevant mode, ownership and extended-attribute import rather than guessing which one failed. The replacement writes to a temporary file beside the final destination with reflink and sparse handling enabled, normalizes the mode, retains the source timestamp where that succeeds, and atomically replaces any prior attempt.
