Proven On Copies, Stopped At The Fallback

This entry covers 2026-10-20. Times are in UTC, as the logs record them. No night report is on file for that date or the next morning, so the entry is built from the day's status files, two backlog sweeps and one ruling from the author. An evening batch run that was under way on the 20th closed at 04:00 on the 21st. Its end state appears here because it is the outcome of the covered day; the next entry owns the post-midnight detail.

The short version

A Codex-run model did the orchestrator's job correctly, but only on copies. Astra, run through the Codex command-line tool, handled all 3 of 3 real, recent hand-backs against copied records. A hand-back is a question the author has answered, which the orchestrator must then record and act on. 27 tests passed, and the final design and prototype reviews each ended with zero serious findings open. The live lock on the orchestrator role was never touched, and no live trial ran.
The install package for that move has three gates; two passed and one did not. The failing gate covers how a Codex-run orchestrator gives the role back. It failed on one scenario: falling back to Claude when the model provider is lost. A reviewer found it and a test then reproduced it. The three-round review cap was reached, and the package checker refused to mark the bundle installable. Nothing was installed.
A capture step was silently keeping only the last 12,000 characters of a command's output. An independent check refused twice to approve work on evidence it could not see whole. One bounded retry, given access to the full record (27 receipts, 847,216 bytes), let the work through to a review, which it passed. A repair to the capture step was built and reviewed but not installed.
The evening batch ended with 14 packages built and reviewed, none installed, and its target of 12 concurrent workers never met. One account was held from new launches all evening for running ahead of its pace line, meaning the share of its weekly allowance it should have used by that hour. At the last reading before midnight it had used 53% against a 35.49% line. API credits spent: USD 0.
The nightly silence sweep found 447 of 504 open backlog items (89%) with no recorded activity in more than 3 days. It also counted 401 of 406 queues with nothing reading them, and 359 task briefs written but never started.
A closure sweep tested the 353 open items whose wording sounds finished: 28 confirmed, 73 left for the author, 252 refuted. GPT-5.6 Luna judged the prose of all 353 in one batched call. A confirmed item closes only after a 24-hour objection window that starts once the author is notified.
The author made one ruling: start all four items on a proposed work list for the Codex side of the fleet, and run a new survey.

What changed in the harness

Nothing reached the live harness on this day. All three changes are staged: built and reviewed, and waiting on a separate install step.

A copy-only Codex orchestrator was completed and passed review. Intent: learn whether a Codex-run model can do the orchestrator's job at all, without putting the live system at risk.
An install package for that move was assembled behind three gates. The gates cover how a Codex-run orchestrator is admitted, how it recovers and keeps its records, and how it gives the role back when its time ends or its provider fails. Intent: make installation impossible until every gate passes review. The package checker enforces this, and installing is reserved for the Claude-run operator.
A repair to the step that captures command output was built and reviewed. Intent: stop that step from silently discarding everything but the last 12,000 characters.

What broke

The fallback gate did not pass

Detected: the third and final review round of the install package left one finding open, and a test reproduced it as a failure. While that round was still running, the gate's own suite read 38 of 38 passing.
Cause: the record names the failing scenario (fallback to Claude after the model provider is lost) and nothing deeper. The root cause is unknown.
Done: the gate was marked blocked at the three-round cap, and the checker refuses an install. There was no install, no live trial and no access to the live lock.
Lesson: a green suite says nothing about paths it never exercises. Fallback paths are the least exercised of all, because they run only after something else has failed. Turn each review finding into a failing test, and let a checker, not a summary, decide whether a package may install.

Evidence silently cut to its last 12,000 characters

Detected: an independent check that sits before review refused to pass a staged fix. It refused first because it could not reach the raw evidence, then because the output it could see had been truncated.
Cause: the step that captures a command's standard output kept only its last 12,000 characters and gave no sign that anything was dropped.
Done:
- The full evidence (27 receipts, 847,216 bytes) was exported and validated. That alone did not help: the check still read the evidence through the same capture step, and refused again.
- Both permitted fix rounds were now used. A question went up whose default was to hold, with no third fix and no forced pass.
- A single retry was granted that changed only what the check could see. The refused attempts' six files were archived by move first, with a map of where each went.
- The retry proceeded on all 27 receipts, and one Sol 6.1 review at maximum effort passed the work with nothing open.
- A repair to the capture step then passed its own single review, and two lower-priority follow-ups went to the backlog.
- Both the fix and the repair are staged, not installed.
Lesson: silent truncation is worse than a crash, because everything downstream still looks normal. A checker should refuse evidence it cannot see whole; that refusal is what caught this. Repairing the evidence achieves nothing while the checker still reads it through the lossy channel, so fix or bypass the channel itself. Make truncation loud where it happens: record that it happened and how much was lost.

A worker started without its instructions

Detected: the launch exited before it ever reached a model.
Cause: it was started without its prompt. The setting that feeds the prompt in on standard input was wrong.
Done: the failed launch was preserved, the setting was corrected once, and the worker was relaunched. It is the worker that built the capture repair above.
Lesson: confirm the brief actually arrived before a worker starts, and keep a failed launch's remains rather than overwriting them.

Baselines that could not be established

Detected: each item's own run record.
Cause: three proposed trims to workspace code could not collect any of their target's existing tests. They found zero, even after two environment corrections each, for reasons the record does not give. A fourth item was granted one replay directly on the workspace machine. It failed before collecting any tests because a mixed-case label in a path had its case inverted.
Done: all four stopped on hold, with no retry, no patch and no review spent.
Lesson: capping environment fixes stops "one more try" from eating the night, and here it worked. But a one-shot grant is easy to waste on a trivial precondition. Check the cheap things first, such as whether paths resolve and case matches.

Most of the backlog has gone quiet

Detected: the nightly silence sweep at 17:35.
Cause: not established. This is a standing condition rather than a new incident, and the record does not say when it began. The sweep's own reading is that whatever writes to these queues still runs and whatever should read them does not.
Found:
- 447 of 504 open items (89%) had gone more than 3 days without a mention in any status file, decision record or gate verdict.
- By their own wording, 100 read as finished but were never closed, 44 are waiting on the author, and 303 are open and stalled.
- 191 have never produced any signal at all. Their ages come from dates quoted in their own text, so they are upper bounds; the oldest, 98 days, is one of these.
- 401 of 406 queues have no reader, but the flow is concentrated. Of the 151 records added since the previous sweep, 150 went into three queues: 108 into a work-queue log, 35 into the queue of memory candidates and 7 into the escalation queue.
- 359 task briefs show no sign that a worker ever started them.
Done: every finding was drafted as its own card for the author, so nothing has to be answered in bulk.
Lesson: a registry that only grows stops meaning "in progress". Measure drain (closures, reads, starts), not intake. This harness also now has two tests for "finished": this sweep's wording test and the closure sweep's dated-and-corroborated test. They run over different sets of items, so their numbers cannot be compared until there is one test.

The closure report mislabels its largest group

Detected: while this entry was being written from the record.
Cause: the heading over the 252 refuted items says each one claims completion and then contradicts itself. That describes only 2 of the 99 refuted items visible before the source is cut off. The other 97 were refuted because the model found no completion claim for the item's own work at all. The heading's second clause, that these items would have been wrongly closed by the keyword rule alone, does hold.
Done: nothing yet.
Lesson: when a model's reading is layered over a keyword filter, labels written for the keyword stage stop describing the buckets. Generate labels from the verdict reasons, or print the count of each reason under each heading.

A coordinator died before writing its handoff (early on the 21st)

Detected: the batch orchestrator's monitoring recorded that a sibling coordinator, which was running four work streams, had exited at 01:54. It exited with model-capacity errors and a failure status, before writing its handoff.
Cause: model-capacity errors, per the record; nothing more specific.
Done:
- The default was to preserve everything and not relaunch, and a recovery question was raised.
- A read-only recovery then assembled a handoff from what remained. It covered 149 workers and 725 recorded processes, all absent when checked at 03:11, with 35 child-process identities unknown.
- The last two workers' results were left unaccepted, and nothing was relaunched.
Lesson: the coordinator had refreshed a draft handoff four minutes before it died. Write the handoff continuously, not at the end. After an unclean exit, recover read-only before restarting anything. A model provider failing under running work is exactly the condition the blocked gate above tests for, and that same night it happened to a different component.

Intentions vs outcomes

Forward: changes made on 2026-10-20

| Change | Intent | Re-check +3 days (2026-10-23) | Re-check +14 days (2026-11-03) | |---|---|---|---| | Copy-only Codex orchestrator | Learn whether a Codex-run model can do the job without risk to the live system | Has a live trial been authorised or run? | If it ran, did the copy results hold live? | | Three-gate install package (staged) | No install until every gate passes review | Is the fallback gate still blocked, and did anything install around it? | Installed, abandoned, or still blocked? | | Capture-step repair (staged) | Stop silent truncation of captured output | Installed? | Does any later record show evidence cut short? |

Backward: check-backs due

No earlier entry's forward ledger is in this record, so the check-backs that fall due today cannot be listed from it. Two checks the record can partly support were made against the record as assembled at 14:35 on 2026-10-21:

| Item | Verdict | Method | Limit | |---|---|---|---| | Memory: the author's standing doubt, re-checked weekly whatever the verdict | UNVERIFIABLE | Read the silence sweep's queue census and quiet list. The memory-candidate queue gained 35 records since the previous sweep with nothing reading it, and at least three items about the memory system are on the quiet list | The sweep sees appends and mentions, not whether candidates are consumed by a path it does not scan. Its list is truncated in the record, and the intention under re-check is not in the record | | An August ruling: a finished-sounding item closes only after individual verification | UNVERIFIABLE | Read the closure report's rule and counts. Classification behaves as the ruling asks: 28 of 353 confirmed, each needing a dated claim, on-disk corroboration and no contradiction | The closure ledger is not in the record, so whether any item actually closed, and whether the 24-hour window was honoured, cannot be seen |

What we still don't know

Why fallback to Claude fails after provider loss. The record names the scenario, not the cause.
Whether copy results carry over to the live role. Live source files still matched their recorded before-state, but no live trial has run.
Which model actually answered the evening's measurement calls. Twelve small measurement runs of the Codex-native setup all completed and validated mechanically. An independent audit and a replay each passed 1,039 of 1,039 checks. But the served model and the context it received are recorded as unknown, an MCP server demanded authentication at every startup, and the result is on hold for missing historical telemetry. No accuracy claim was made.
Whether the evening's four Codex work streams and its six-row survey are the four items and the new survey the author approved. The record never ties them together.
What happens to the 252 refuted closure candidates. The report's method says everything not confirmed goes to the author. Its tables then separate 73 "needs the author" items from the 252, and say nothing more about the 252.
How far the quiet count understates neglect. Any mention counts as activity, and some mentions are bulk: one decision record is the latest "activity" for seven quiet items, and another is the latest for six. A bulk mention inside the 3-day window keeps an item off the list whether or not anything happened to it. How often that occurs is not in the record. The item tracking this series of posts is itself on the quiet list, last mentioned 92.4 hours before the sweep, and the record does not say whether writing these posts would register with the sweep at all.
Whether anything is lost in the escalation queue, where the harness raises questions for a decision. The sweep lists it among the queues nobody reads (7 new records). Yet both questions visible in the evening's record were answered within the hour by a supervising session. Which path carried them is not in the record.
The edges of the closing census. All 144 recorded processes were gone at 04:01 on the 21st. However, 24 historical start identities could not be confirmed, and any process the harness never recorded falls outside the census.
What the record omits. The source pack was capped at 180 KB and both sweep reports were cut at 40 KB, so counts taken from their tables cover only the visible rows.

Technical detail

Copy-only orchestrator proof. Fixtures were copied from the live escalation queue, note inbox and decision log. For each hand-back the prototype produced an "answer" operation and a "rule" operation, each with its own receipt. The design documents and the prototype were reviewed separately, three rounds each. Both ended with no open findings at the top two severities (P0/P1), and 27 tests passed at the end.

The three gates.

Admission: a Codex-run orchestrator is let in by its own path, while the existing Claude path's regression tests stay green.
Recovery and records: recovery to the canonical state, notes and holds carried in full, receipts and a pinned package. It passed 26 of 26 tests plus 4 of 4 interface tests; its first review raised ten findings, all addressed.
End-of-tenure custody: cutoff and return of the role. It passed 38 of 38 tests before the final round's finding.
Before the verdicts: a fresh rehearsal with the actual Astra and Sol models passed 3 of 3 on copies, and install, rollback and repeated rollback were exercised across 12 paths on a copy.
Review outcomes: reviews were capped at three rounds per gate. Admission passed in round three and recovery in round two; custody was blocked in round three with one finding open. The package checker then refused to mark the package installable.

Admission control for the evening batch. Each launch needed a fresh read of authority, pace and resources.

Pace: the account ahead of its pace line was held all evening. The other account, well under its line, took every new launch in the evening's record. An 8-point reserve was held back for reviews.
Resources: launches were gated by a memory fence of 19,900 MiB committed against a 61,440 MiB limit, with a 1,024 MiB margin. There were also floors of 6.0 GiB free memory and 110.0 GiB free disk on the root volume; the last readings before midnight were 30.7 GiB and 332.1 GiB.
Counting: launches are counted by actual process ids, not completed tasks. The orchestrator made 111 over the run.
Bounds: the run had a hard end at 04:00 and stop markers, all present at close.
Shortfall: in its closing hours the orchestrator repeatedly found no newly admissible task. The record attributes the unmet concurrency target to accepted supply and pacing limits.

Fix and review caps. The truncated-evidence item allowed two pre-review fix rounds, then one maximum-effort Sol 6.1 review. A refusal by either the pre-review check or the review was set to be a terminal hold until the next reset, with no third fix and no forced pass. Each of the four items that hit environment problems stopped after two corrections. Two one-shot grants were issued by a supervising session and each used once: the access-only retry and the single replay on the workspace machine.

Capture repair. It changes exactly one existing file. The replay ran 30 checks across 52 full-script fixtures: 25 passing, the original failure reproduced, and 4 seeded faults. 7,060 file hashes were compared before and after, and live files were unchanged. Its tests captured bytes from real pipes but faked the endpoints on the far side, so it has not been exercised against the real ones. Interrupt cleanup and display of the end of the error stream are deferred.

Closure sweep. For each item the deterministic evidence is:

whether any file it names exists;
whether its next-action cell is empty;
the closure word used;
any dated marker.

Three questions about the prose are answered by a keyword scan or, as here, by one batched model call over all candidates: does the item claim its own work is done, is the claim dated, and does current work contradict it. The verdict is a fixed table in code: confirmed needs a dated claim, on-disk corroboration and no contradiction. A delivered notice to the author opens a 24-hour objection window before a confirmed item is closed. The tool does not rewrite the registry itself.

Silence sweep. Quiet means more than 72 hours since the latest mention in any status file, decision record or gate verdict. For an item never mentioned, the sweep falls back to a date in the item's own text. Inputs this run:

589 registry items (504 open, 85 closed);
3,402 status files and 4,642 decision records;
2,283 gate commissions and 3,791 gate verdicts;
406 queues holding 966,185 records;
2,121 task briefs;
0 unparseable inputs.

A queue counts as dead when nothing drains it. A dispatch counts as unstarted when its brief has no matching status file.
