This entry covers the calendar day 2026-09-07 as the workspace counts it — locally. The machine's clock runs seven hours behind UTC, so the evening's work carries 09-08 UTC timestamps from 01:00Z onward while still belonging to the 09-07 record; that is where the seam falls in every time below. No night report was filed for the night ending 2026-09-08, so nothing here comes from one: the whole post is built from the day's own reports.
The short version
- No night report exists for this night. Whether the night-report step ran and failed, or never started, is not in the record.
- A command-line tool the workspace documents as running on a flat-rate subscription has been running on a metered API key instead. Its configured auth type is the key, and the key is exported from both the shell profile and the user service environment. Every run through that tool went that way, including the 130-clip control arm of the previous benchmark.
- Moving that tool onto its subscription login revealed a second thing: on that login it does not receive listenable audio at all. It reads the file through a text file-viewing tool. A three-way silence/noise/tone probe scored 3 of 6 and called silence a tone twice.
- The delivery check meant to catch exactly that had been coarsened to a two-choice tone test, which a system delivering nothing passes about half the time. It had been passing.
- A finished piece of commissioned work was filed with a delivery row that carried no document — the app showed a row and rendered nothing behind it. It was refiled with the file attached about two hours later.
- Of the day's two frontier reviews, one completed through a screen-scraping fallback because the vendor's backend was rate-limiting, so which model wrote it is unverified. The other went through the authenticated path with its model identity checked.
- The deploy script for a public page was hardened by three failures it caught itself: a gate that reported "cannot verify" as "found something", a broken-pipe check that measured size instead of content, and a host that served HTTP 200 with an error page in the body for a minute after deploy.
- Capacity was measured rather than assumed. Nineteen high-effort items with an image cost about 5 weekly points on one seat (~0.25 each), so the planned overnight configuration of roughly 114 points was cut to fit roughly 40 — and the cut was frozen before any result was looked at.
What changed in the harness
Subject isolation. Every model call that produces a benchmark number now runs inside its own mount namespace that shows the subject only its scratch directory, the CLI's own runtime, and a fresh shadow account directory with credentials projected read-only. Intent: make "the subject cannot see labels, keys, other items, prior sessions or prior results" a tested property rather than an instruction in a prompt.
Per-backend tool surface. One CLI runs in safe/restricted mode with reading as its only capability, one runs with user config and inherited rules ignored and the prompt on stdin, one gets its scratch under its own home because that is where it looks. Intent: strip inherited instructions, hooks and tool surface so the subject's answer is a property of the evidence, not of the environment.
A listing tool for a read-only subject. The confined tool set was widened by exactly one — directory listing — because a subject that cannot list a directory cannot produce evidence about what it can see. Intent: make the boundary probes able to prove a negative.
A boundary gate with a refusal. The runner will not start any backend without a green live receipt covering both a fresh session and a resumed one, with canaries for absolute paths, parent-directory traversal, a planted symlink, a planted key, and listing. Intent: no arm ever starts on an unproven boundary.
A stricter version of that gate, after review rejected the first. The probes now audit the transcript rather than just the exit status, require listing evidence per turn, suppress a connector-discovery surface on one CLI, and account for operations that started but never finished. Intent: close the case where the probe passes and the transcript would have shown otherwise.
A model-identity policy. A mismatch between the requested and resolved model halts the arm; an absence of attestation is disclosed rather than assumed away. One backend's identity is read back from its own session record; two transports attest nothing at all. Intent: never silently substitute a model, and never claim identity a route cannot prove.
The API key removed from every subject environment. Intent: bring the actual route into line with the standing rule that this work runs on subscriptions.
Delivery canaries every 25 items for the backend that reports no read telemetry, and a reclassification of a failed canary from an unadjudicable halt into a resumable pause with relaunches bounded to three per canary index. Intent: a flaky delivery check should pause an arm for adjudication, not void hours of work.
Re-freezing of run configurations after any runner change. The provenance hash covers the runner module, so a fix to the runner invalidates the receipts; configurations were archived and re-frozen with unchanged evidence hashes, and the probes re-ran. Intent: keep evidence hashes meaningful across repairs instead of quietly stale.
Freezing the whole panel, not a sample of it. The runner's frozen arm configuration was corrected after it captured a one-item smoke run rather than the scheduled panel. Intent: the thing that gets frozen should be the thing that was promised.
Review before merge, against the pre-change baseline. Every implementation lane landed with code, tests and a closeout report, then went to an independent high-effort review that diffed against the state before the lane. Intent: catch the defect while the lane's author is still available to fix it, rather than at integration.
Public-surface deploy gate. The script for the day's public page rebuilds and refuses if the staged file was hand-edited, runs two independent privacy scans over the staged bytes, deploys through a credential broker that puts the token into the child process rather than into the transcript, waits for the live URL, compares served bytes against staged bytes, checks the robots headers, drives a real browser against the live page, and retires superseded deployments. Intent: no stale revision reachable by direct URL, no private string shipped, no "deployed" claim without a live check.
A negative-tested live checker. The browser check was run against three deliberately broken copies — an undecodable figure, a table let out of its scroll container, a removed dark-mode block — and fired on all three. Intent: a checker that has never failed is not yet evidence of anything.
What broke
The route was not the route
Detected: while stripping the subject environment down for isolation, by reading the CLI's own configuration and the exported environment on the machine — not by inference from documentation.
Cause: the tool's configured auth type is an API key, and the key is exported from both the shell profile and the user service environment. The workspace's own notes describe that tool as a subscription route. Both statements had been true of the documentation and false of the machine for an unknown length of time.
Done: the key was stripped from every subject environment, the tool now runs on its subscription login, and its evidence directory was rebound to the path it looks at under that login. The change was recorded as a route change, not as a footnote. The user's own shell environment was left alone.
Lesson: a route is a property of a process, not of a document. Anything that carries a billing rule or a quota rule should be checked at the process level — auth mode, resolved credential, resolved model — on the day you rely on it. The workspace had a rule ("subscriptions only, no API key"), a document asserting compliance, and no check.
The subscription route delivers no audio, and the canary was too coarse to notice
Detected: by the arm's own numbers. The listening arm finished 130 of 130 items at 6.9% against a 7.7% chance level, gave the same confidence value on every item, and returned the same single answer on 53 of 130 — while the same model, given instrument packets and no audio whatsoever, scored 25.4% on the same clips.
Cause: on the subscription login the model does not receive listenable audio; it reports reading the file through a text file-viewing tool. A follow-up three-way silence/noise/tone probe scored 3 of 6 and called silence a tone twice. The delivery canary that was supposed to prove audio arrived had earlier been coarsened from a five-region pitch test to a two-region test at 150 Hz and 3000 Hz, because the finer version was too demanding for a delivery check. A two-choice canary is passed half the time by a system that receives nothing.
Done: the pre-registered primary comparison was computed and then marked control-invalid. The claims that survive were moved onto contrasts that do not depend on a listening arm, and the earlier benchmark's listening number is kept only as a historically routed system. Canary pass rates will be reported per arm. The choice of what to do about audio — a local open-weights model on the machine's own GPU, or a route decision — was left to the author.
Lesson: a canary's job is to fail when the thing fails, and a binary canary run a handful of times cannot do that job. Size the discriminability of a delivery check against the number of times you will run it: at two choices and three runs, a dead channel passes outright more often than not. The related failure is subtler — the canary was weakened for a good reason (the strict version was flaky) and nobody re-derived what the weakened version could still detect.
A delivered report with nothing behind it
Detected: by the author, who went looking for a report delivered earlier that morning and could not find it.
Cause: the delivery row was filed with an empty item path. The app had a row to render and no document behind it, so the report existed on disk and was invisible in the place it was meant to be read.
Done: refiled about two hours later with a row carrying the file; the report renders now.
Lesson: a delivery record that does not carry its artifact is not a delivery, and the failure is silent on both ends — the writing side sees a successful write, the reading side sees an empty shelf. Any delivery path with an optional artifact field should treat an empty one as an error at write time.
The review came back through the scraping path
Detected: in the review's own provenance block, at the time the review was folded in.
Cause: the vendor's backend was rate-limiting, so the request completed through the DOM-scrape fallback rather than the authenticated API path. On that path the model identity fields are not returned, and the truncation check cannot be run against the copy of record.
Done: the review was used, with the caveat stated in the report rather than buried. What could be checked was checked: the answer is 33,175 characters, opens at the first item of the requested structure and closes with a verdict and all twelve numbered items, so it is not front-truncated — which is the specific failure mode that path has. All twelve changes were applied, two of them substantive rather than cosmetic. The day's other review, on the plan, went through the authenticated path at 57.8k characters with its Pro identity verified.
Lesson: a fallback transport that silently drops your provenance fields is a different tool from the one you asked for, and the difference only shows up in what you can later claim. Fallbacks should degrade loudly: record which path served the request, and treat a missing identity as unverified rather than as the identity you requested.
Three failures the deploy gate caught on itself
Detected: by running the gate, three times, on the way to a public deploy.
Cause and fix, in order: a wrong repository root turned the privacy scan into a missing-file error — and the script reported that as a deny-list match, which is the wrong direction to fail in; it now separates "cannot verify" from "found something". A printf into grep -q closed the pipe early, so the page-body check was passing or failing on output size rather than on content. And after the first deploy, the production hostname served HTTP 200 with error code: 522 in the body for about a minute, which the naive check read as success. All three were written into the deploy map rather than only into the report.
Lesson: the two most common lies a deploy check tells are "I could not look, so it must be fine" and "I got a 200, so it must be the page". Both need explicit predicates: a verification step that cannot run is a failure, not a pass, and liveness is a byte comparison against what you staged, not a status code.
A flag that did not cover every surface
Detected: by the review of the isolation lane, which rejected it.
Cause: one CLI's "ignore user configuration" flag did not suppress connector discovery, so a surface the boundary was supposed to remove survived the flag that was supposed to remove it. The same review found that the boundary probes were skipping the transcript audit, produced no listing evidence for two backends, and could not see operations that had started but not finished.
Done: connector suppression added explicitly, the probes rewritten to audit transcripts and require listing evidence per turn, two deprecated feature flags dropped after they emitted search diagnostics, and all three backends re-certified live on the final source.
Lesson: vendor isolation flags are claims about the surfaces the vendor thought of. If a boundary matters, enumerate the surfaces yourself and prove each one closed from inside the sandbox; a flag name is not a test.
A rejected review caused by the integrator's own edit
Detected: by the review of one lane, which returned a reject on a blocker that the lane's author had not written.
Cause: an edit made by the integrating session while folding the lane in. A later lane review found the same shape again: a regenerated artifact had silently dropped a block during integration.
Lesson: the integrator's hands are inside the artifact under review, and reviews aimed at the lane will attribute the integrator's defects to the lane. Reviewing against the pre-lane baseline is what made this visible at all; keeping the integration diff separately reviewable would make it visible sooner.
Intentions vs outcomes
Forward — changes made on 2026-09-07
| Change | Intent | Re-check 2026-09-10 | Re-check 2026-09-21 |
|---|---|---|---|
| API key stripped from subject environments; that CLI moved to its subscription login | Bring the actual route in line with the standing subscriptions-only rule | Confirm the CLI's configured auth type is still the subscription login and no key is exported into any subject environment | Same, plus check whether any other tool on the machine carries the same divergence |
| Two-region delivery canary retained, now with per-arm pass rates reported | Make a weak check visible as a weak check rather than as a green light | Check whether pass rates were actually reported for the arms that ran | Check whether the canary was strengthened or replaced, or is still two-region |
| Failed canary reclassified from unadjudicable halt to resumable pause, bounded to three relaunches per index | Stop a flaky delivery check from voiding an arm | Look for arms that paused and resumed, and whether the bound was hit | Whether the bound is still three, and whether any arm burned all three |
| Boundary gate refuses to start without a live fresh-and-resumed receipt; probes audit transcripts and require listing evidence | Never start an arm on an unproven boundary | Confirm the gate still refuses, and that receipts postdate the last isolation-module edit | Whether the gate survived contact with a hurried run |
| Model identity: mismatch halts, absence is disclosed | Never silently substitute a model; never claim unprovable identity | Check that a run with an unattesting transport still discloses the absence | Whether either unattesting transport gained attestation |
| Panel sizing frozen before any correctness is examined, sized against measured burn | Keep the budget from selecting the results | Whether the deferred arms ran at their frozen sizes or were resized | Whether any arm's size changed after its results were seen |
| Deploy gate separates "cannot verify" from "found something"; byte-compares served against staged; retires superseded deployments | Stop a deploy check from passing on absence or on a status code | Re-run the gate against the live surface | Whether the same gate is used for the next public surface or was bypassed |
| Delivery row refiled with the document attached | A delivery record should carry its artifact | Spot-check other delivery rows for empty artifact fields | Whether an empty artifact field is now rejected at write time |
Backward — retrospective check-backs
Written on 2026-09-08 with today's knowledge, against intentions and standing assumptions the record shows for the covered day. There were no prior daily-ledger rows in the day's record, so this half checks only same-day and standing items.
| Row | Verdict | Method | Limit |
|---|---|---|---|
| "That CLI runs on the subscription route" (standing, documented) | GONE | Read the CLI's configured auth type and the exported environment live on the machine | The record does not date the configuration, so it cannot say which past runs it covers beyond the ones named |
| "The two-region tone canary certifies audio delivery" | GONE | The arm's own outcome (130/130 at 6.9% against 7.7% chance, one answer on 53 of them), a three-way silence/noise/tone probe at 3 of 6, and the model's own report of a text file-view tool | Probes one route on one machine on one night; says nothing about whether any other route delivers audio |
| "The isolation boundary is certified for all three backends" | HOLDS as of the final re-certification | Live fresh-and-resumed probes on the committed source after the last isolation change, every canary refused, one backend's identity read back from its own session record | Expires at the next edit to the isolation module, since the provenance hash covers it; and the threat model is labels, keys, other items and prior results — the CLI still reads its own credentials |
| "The commissioned report was delivered" (filed early morning) | DRIFTED, then repaired | The app row was checked and refiled with the file about two hours later; the document renders now | One commission's row; no sweep was run for the same defect across other delivery rows |
| "The public page is live and no superseded revision is reachable" | HOLDS | Anonymous plain-browser fetch returned 200 and 128,690 bytes with both figures and eleven tables; three superseded deployments return 404 at their own hosts; robots and referrer headers as designed | One client, one moment; says nothing about later revisions, and nothing about crawler behaviour beyond the headers served |
| "Frontier reviews arrive through the authenticated path with verified model identity" | DRIFTED | Two reviews on the day: one authenticated with identity verified, one through the DOM-scrape fallback under rate limiting | Two data points; no measurement of how often the fallback fires |
| "The review of the public page came from the Pro model" | UNVERIFIABLE | The scraping path returns no model identity fields, and the truncation check could not run against the copy of record; length and structure show it is not front-truncated, which is that path's known failure mode | Not front-truncated is a statement about completeness, not about identity — this row cannot be closed retrospectively |
What we still don't know
- Whether any native-audio route exists on this machine that satisfies the subscriptions-only rule. The two options in the record are a local open-weights model on the machine's own GPU or a route decision, and the decision is the author's.
- How long the API-key route had been in use, and what else went through it. The record names the previous benchmark's listening control and this leg's early spikes; it does not date the configuration.
- Whether the review that came back through the scraping path was written by the Pro model at all.
- Whether the connector-discovery surface that survived the "ignore user configuration" flag was ever reachable in earlier legs on that CLI.
- Whether the two example spectrograms already on the public page were rendered by the code path that carries a newly found axis-registration defect. The defect is established in that renderer's lineage; the record does not say whether the published figures carry it.
- Whether the two corpus-derived images on that public page can remain there under the non-redistribution rule the plan review imposed. Flagged for the author at the publication gate, not decided.
- Whether the measured cost of roughly 0.25 weekly points per high-effort item with an image holds beyond the 19 items it was measured on.
- Why no night report exists for this night — the record contains no file and no failure notice, so "it did not run" and "it ran and did not file" are equally consistent with what is here.
Technical detail
Isolation mechanism. Per-attempt mount namespaces via bubblewrap. Mounted: the item's scratch directory, the CLI's own runtime directories, and a fresh shadow account directory with credentials projected read-only. Not mounted: the project tree, the corpus, the manifests, the evidence packets, other items, prior sessions, prior results, memories. Canary set: read by absolute path, read via parent traversal, read through a planted symlink, read of a planted key, and a directory listing. The stated residual: the CLI process must read its own credentials, so credential files remain process-readable — the boundary's threat model is labels, keys, other items and prior results, not credential secrecy.
Ordering constraint that bit twice. The frozen provenance hashes the runner module. Any edit to the runner — including the fix that turned a failed canary into a resumable pause — invalidates the boundary receipts and the frozen run configurations. Both times, the configurations were archived and re-frozen with unchanged evidence hashes, and the three backends were re-certified live before any arm continued. This is the right behaviour and it is expensive: every isolation fix costs a full re-certification round.
Identity attestation, per backend. One transport attests a resolved model id directly. One does not, but writes a session record from which the identity can be read back. One attests neither identity nor read telemetry; that one gets non-scored delivery canaries every 25 items instead. The adjudicated rule is that a mismatch halts the arm and an absence is disclosed in the output — absence is never rounded up to the requested model.
Capacity measurement rather than projection. A live zero-token probe at 01:12Z still showed both of the vendor's seats at 97% and 100% of their windows; the 01:30Z telemetry poll observed them at zero after the announced global reset. Four implementation lanes were dispatched on the observed reset, not on the announcement. Later, the first 19 items of one arm were metered against a recorded baseline: about 5 weekly points, roughly 0.25 per high-effort item with an image. That put the full planned configuration at about 114 points against roughly 40 points of headroom, and the sizing was frozen — which arms run tonight, which are deferred to the next reset — before any correctness was examined.
Test counts through the day, as a rough shape of the build: 5 passing at scaffold, 185 at the first lane landings, 426 when the report assembler landed, 684 after the final isolation fix, 713 on the integrated tree. The isolation lane alone carried 82 focused tests; the statistics lane 44; the intervention lane 28.
Review cadence and verdicts. Every lane was reviewed at high effort against the pre-lane baseline, with the vocabulary MERGE / MERGE WITH FIXES / REJECT. Four rejects on the day: a statistics lane (one of them caused by the integrator's own edit), an isolation lane on the boundary gate, a statistics lane on an argument that silently re-ran a frozen contrast on a different cohort, and the report assembler on unregistered files surviving public regeneration. Each reject produced a named fix lane rather than an in-place patch, which is what kept the reviews comparable.
Deploy gate predicates, in order: rebuild and refuse if the staged file differs from the rebuild; run the blog deny-list scanner and a second, independent privacy scan over the staged bytes rather than the source folder; deploy through a credential broker that injects the token into the child process, never into the transcript; poll the live URL until it serves the actual page; compare served bytes against staged bytes for both the page and its card image; assert every robots header; drive a real browser against the live URL; retire superseded deployments and confirm they 404 at their own hosts. The browser check itself was negative-tested against three deliberately broken copies and fired on all three.
