From eaa95047932bf611b31df321db0069632060bb44 Mon Sep 17 00:00:00 2001 From: Edbert Chan Date: Sat, 12 Sep 2026 20:01:53 -0700 Subject: [PATCH 01/18] [Hooks Cannot See] (2) Require the output to entail the claim, not merely agree The session behind slice (1) ran one command against one container image and proved that image had no corepack. That was written up as corepack having been removed from Node 25+, a version-boundary claim no command in the session ever checked. The output was true and the sentence was wider than the output. prove-it already covers a missing check and a hedge. It did not cover a check that ran, came back narrower than the claim, and got filed under the wider heading anyway -- which is the common case, because the cheap check is always the reachable instance. It binds hardest in a correction: restating the original overclaim while pasting a narrower proof relabels the mistake as a fix, which is what happened here before the rule existed.

charset=UTF-8 Content-Transfer-Encoding: 8bit Solution: Append the judge answer's report string to a hit message in the llm-judge inbox. Review claim: inbox.messages() returns on_hit followed by a space and answer["report"] when the verdict is a hit and report is a non-empty string, clipped to 600 characters; every other verdict produces the same text as before. Review lane: behavior Safety invariant: A verdict whose answer carries no "report" string yields byte-for-byte the same message as today, so wrong-check-reflect and diu-stop messages are unchanged. Clean verdicts still produce nothing. Effectiveness measurement: Unit tests prove a hit with a report ends with that report, a hit lacking one equals on_hit exactly, a report over 600 characters is clipped, and a non-string report is ignored. Slice rationale: One behavior slice in the inbox, dormant because no current judge prompt asks for a report key; the hook that asks for it lands next. Architectural effect: The inbox can carry per-verdict evidence text from the model to the agent. Goal: Let a judge tell the agent what it found, not just that it found something. Motivation: The planned unverified-tag check must report whether a "cannot verify" blocker and its claim were true or false, with the file or quote that shows it. A fixed on_hit sentence cannot carry that. Alternative considerations: Building the message inside the hook at enqueue time was rejected because the answer does not exist until the background run ends. A new verdict field was rejected as more surface than one optional answer key. Implementation details: In engine/hooks/llm-judge/inbox.py, in messages(), after picking the hit text, read item.get("answer"); when it is a dict whose "report" value is a str with non-blank content, append " " plus that value stripped and clipped to REPORT_LIMIT = 600 characters.

charset=UTF-8 Content-Transfer-Encoding: 8bit Context: wf-1789279268766-11/implement-inbox-report-line (0d98bfa): Append the judge answer's report string to a hit message in the llm-judge inbox. Review claim: inbox.messages() returns on_hit followed by a space and answer["report"] when the verdict is a hit and report is a non-empty string, clipped to 600 characters; every other verdict produces the same text as before. Review lane: behavior Safety invariant: A verdict whose answer carries no "report" string yields byte-for-byte the same message as today, so wrong-check-reflect and diu-stop messages are unchanged. Clean verdicts still produce nothing. Effectiveness measurement: Unit tests prove a hit with a report ends with that report, a hit lacking one equals on_hit exactly, a report over 600 characters is clipped, and a non-string report is ignored. Slice rationale: One behavior slice in the inbox, dormant because no current judge prompt asks for a report key; the hook that asks for it lands next. Architectural effect: The inbox can carry per-verdict evidence text from the model to the agent. Goal: Let a judge tell the agent what it found, not just that it found something. Motivation: The planned unverified-tag check must report whether a "cannot verify" blocker and its claim were true or false, with the file or quote that shows it. A fixed on_hit sentence cannot carry that. Alternative considerations: Building the message inside the hook at enqueue time was rejected because the answer does not exist until the background run ends. A new verdict field was rejected as more surface than one optional answer key. Implementation details: In engine/hooks/llm-judge/inbox.py, in messages(), after picking the hit text, read item.get("answer"); when it is a dict whose "report" value is a str with non-blank content, append " " plus that value stripped and clipped to REPORT_LIMIT = 600 characters. Add tests to engine/hooks/llm-judge/tests/test_inbox.py. Non-goals: No change to judge.py, to unchecked or clean handling, or to any hook. No README edit in this task.

Solution: Describe the report line in the llm-judge README's inbox section. Review claim: The "Delivery: the inbox" section of engine/hooks/llm-judge/README.md says a hit whose answer carries a report string ends with that report, clipped to 600 characters. Review lane: docs Safety invariant: Only engine/hooks/llm-judge/README.md changes; no code or test file is edited. Effectiveness measurement: grep finds the word report and the number 600 in the README inbox section. Slice rationale: The README line for the behavior in this same pull request, which catstack's ship-a-detector playbook requires to ship together. Architectural effect: None; README only. Goal: Keep the inbox contract in the README accurate. Motivation: catstack keeps every hook's contract in its README. Alternative considerations: A later README-only pull request was rejected; the playbook counts that as a known repair pattern. Implementation details: Edit the hit bullet under "## Delivery: the inbox" in engine/hooks/llm-judge/README.md. Non-goals: No code or test edits.

detector require the check's OK result, not merely its invocation. Review claim: A landing check that printed FAIL or UNCHECKED does not satisfy the landing-proof hook. Review lane: behavior Safety invariant: No merge shape that is silent today becomes noisy: a merge followed by a landing check printing OK stays silent, and only FAIL, UNCHECKED, or a missing result newly flags. Effectiveness measurement: Three fixtures: a landing check printing OK stays silent, one printing FAIL flags, one printing UNCHECKED flags. The current detector passes only the first, so the suite fails before the change and passes after. Slice rationale: One detector and its tests in one hook directory; shares no file with the sweep-skill chain, so it runs independently rather than waiting on it. Architectural effect: The detector gains access to each command's paired tool result, so the hook judges outcomes rather than invocations. Goal: Change engine/hooks/gh-write-verification/detect.py so _proves_landing requires the paired tool result to report OK, and add tests for the FAIL and UNCHECKED cases. Motivation: The hook's own purpose is to stop a merge claim that outran its landing check. Because it reads only the command text, a check that ran and reported failure clears it exactly as well as one that reported success, so the failure mode it exists to catch is the one it cannot see. Alternative considerations: Parsing the exit code alone was rejected because the script prints its verdict on stdout and an exit code is not available for every recorded command shape. Leaving the detector as-is and adding a prose rule was rejected: the detector is the mechanism, so prose would be a second copy of the same rule with no enforcement. Implementation details: Extend bash_commands_this_turn (detect.py lines 369-391) to carry each command's paired tool result alongside its text rather than discarding non-assistant records. Change _proves_landing (detect.py lines 291-302) to require an OK marker in that result, treating a missing result as not proving landing. Update merges_missing_landing_proof (detect.py line 306) to pass the results through. Add tests asserting a FAIL result and an UNCHECKED result both still flag, and that an OK result stays silent. Non-goals: Does not change the verifier script's exit contract, does not change which commands count as merges, does not widen the hook to other tools, and does not touch any skill prose.

Invoker-Finalize-Id: 657b1e05-5809-43b8-a2ea-e4ef235c90a4 From e5cbc53c4ab0b341d34b8ec284917c37eb15ca2d Mon Sep 17 00:00:00 2001 From: Edbert Chan Date: Sun, 13 Sep 2026 12:02:10 -0700 Subject: [PATCH 15/18] Revert "Perf playbook: measure, identify, fix, verify with a rerunnable ledger (#549)" This reverts commit 0a2eb69c96f1e8e6f1f8c23229327d2e333fffbb. A backtest found 11 of the skill's 18 case ledgers misstate their source episode: extra runs and after-values were invented to fit the verdict rules, so its passing tests do not reflect the real episodes. The PR was closed for a restart with the backtest as the first step, but it had already been merged through the admin-bypass landing queue.

principle-prove-it: example where the pasted output is narrower than the claim The skill test coverage gate requires a test change with any rule-shaped SKILL.md change. The new entailment rule gets a fires_ example, matching how the subagent-contradiction rule got fires_subagent_contradiction.md.
