You are an independent reviewer with no stake in prior conclusions. Review the ENTIRE branch feat/l5-meta-improvement against origin/main (run git diff origin/main...HEAD — do NOT limit yourself to the latest commit). This branch adds an "L5" meta-improvement layer: a versioned improvement policy (docs/improvement-policy.json), scripts under scripts/ (improvement_policy.py, detect-recurring-pattern.py, archive-round.py, measure-policy-validity.py, revise-improvement-policy.py, mine-trace-failures.py, render-rsi-dashboard.py and their _test.py), workflows under .github/workflows/ (codex-review.yml, revise-improvement-policy.yml, archive-and-recommend.yml), and docs (docs/plans/recursive-meta-improvement.md, docs/rsi/). Threat model: the meta-improver (an AI) may only rewrite the policy it owns; it must never be able to widen its own authority, game its own evaluation (coverage/validity), corrupt the archive or verifier, or accept a revision on evidence that does not support it. Findings should be things that are actually wrong, with a concrete reproduction. Run commands to verify: python3 -m pytest scripts/ -q -p no:cacheprovider, ruff check scripts/, and targeted python3 - <<'PY' ... PY reproductions. Never claim a result you did not observe. Output format: a numbered list of findings, each tagged [P1] (must fix), [P2] (should fix) or [P3] (nit), each with file:line, the failure scenario, and how you reproduced it; then a "## Verification" section listing the commands you ran and their results; then a "## Verdict" line: whether the branch, as a whole, holds its stated invariants. If you find nothing in an area, say so explicitly. SCOPE A — the Python scripts and their tests (scripts/*.py). Check especially: policy hash/versioning, rollback and ancestor logic, the evidence-binding rules (definitions, name@tag variants, truncation, undated traces), the wait gate on unjudged revisions, topic mining bounds, output guards (assert_ai_may_write roles, assert_safe_output), the failure miner's false-positive/false-negative behaviour, and whether the tests actually pin the behaviours the docstrings claim. Also read docs/plans/recursive-meta-improvement.md "Invariants" and check each of the 11 invariants against the code — report any invariant the code does not actually enforce.

I’ll review the full branch diff, check the 11 documented invariants against the scripts, and run the required checks plus targeted reproductions for any findings.

This document maps that framework onto the\nself-improvement loop this repository already runs, names the gap, and records how the gap was\nclosed.\n\n## The framework in one table\n\nThe closed improvement loop has seven parts: AI system, improver, strategy, target, verifier,\nimprovement, successor. Autonomy is measured by how many of those decisions have moved from fixed\nhuman infrastructure into the AI's own persistent state:\n\n| Level | Human keeps                        | AI internalizes        | Retained update       | Here                                                          |\n| ----- | ---------------------------------- | ---------------------- | --------------------- | ------------------------------------------------------------- |\n| L1    | objective, strategy, validation    | execution              | task outcome          | Claude Code applies a round's fix                             |\n| L2    | objective, task bounds, validation | search rules           | search strategy       | each round chooses what to try from the previous findings     |\n| L3    | environment parameters, validation | data generation        | practice curriculum   | `analyze-traces.py` / `sync-pr-traces.py` pull session traces |\n| L4    | governance rules, rollbacks        | state management       | deployed state        | `archive-round.py` + `archive-and-recommend.yml`              |\n| L5    | final oversight                    | the improver mechanism | the verifier/improver | `revise-improvement-policy.py` (this change)                  |\n\nL5's benchmark in the deck (A-Evolve-Training): the system revises its own research policy when\ndevelopment scores stop predicting external gains, then uses the revised policy to direct the next\nround.\n\nThree failure modes the design must guard against:\n\n1. **Safe inheritance** — self-modification that degrades over time. Needs transfer tests, version\n   history, automatic rollback.\n2. **Autonomy attribution** — better candidates mistaken for a better search process. Needs explicit\n   separation of AI-controlled logic from fixed infrastructure.\n3. **Reliable verification** — repeated evaluator access rewards exploitation. Needs evaluators\n   frozen per epoch and an independent ground-truth anchor.\n\n## The gap\n\nBefore this change the loop was L4. `scripts/detect-recurring-pattern.py` decided\ntarget-vs-mechanism fixes from a keyword taxonomy and a threshold that were constants in the file:\nwritten once by hand, never measured, never revised. Two consequences were visible in the real\narchive:\n\n- 11 of 28 archived findings (39%) matched no topic at all, including every finding from rounds 8 to\n  10 (archive threshold crossings, workflow concurrency, PR-creation recovery). A blind spot never\n  accumulates toward the mechanism-fix threshold, so the loop could not notice its own newest\n  recurring problem.\n- Nothing checked whether a topic the reviews kept crediting ever appeared in actual working\n  sessions.\n\n## What changed\n\n- `docs/improvement-policy.json` — the taxonomy, per-topic weights and threshold as a versioned\n  document (`version`, `parent`, `origin`). `detect-recurring-pattern.py` reads it; the old module\n  constants remain as views of the loaded policy so every caller keeps working.\n- `scripts/improvement_policy.py` — load/validate/hash the policy, version it, and the attribution\n  guard: `assert_ai_may_write` refuses any write outside the two AI-owned files.\n- `scripts/measure-policy-validity.py` — the L5 trigger. Coverage (classified / total findings) and\n  predictive validity (Spearman agreement between review-derived recurrence and Traces evidence from\n  working sessions), replayed per archive round using only what existed at that round's timestamp.\n  The verifier's own Codex review transcripts are excluded from the anchor by default; an empty\n  anchor is treated as no anchor, so nothing is discounted for failing to appear in a field nobody\n  observed.\n- `scripts/revise-improvement-policy.py` — the meta-improver. Fixed acceptance rule (constants, not\n  policy fields): revise when coverage < 0.8 or validity < 0.3; roll back when an adopted revision's\n  coverage falls below its parent's after two further rounds. Revisions are bounded: at most two\n  mined topics, each backed by at least two previously unclassified findings, keywords chosen by\n  document frequency, appended after existing topics so nothing already classified changes bucket.\n  Every version is appended to `docs/improvement-policy-history.jsonl` with a full snapshot.\n- `scripts/render-rsi-dashboard.py` — `docs/rsi/dashboard.html`, a self-contained page rendered from\n  the archive, the policy history and the evidence files: autonomy matrix, the loop with live\n  values, the trigger chart, policy lineage, the three failure-mode guards, and every finding under\n  v1 and under the current policy.\n- `.github/workflows/revise-improvement-policy.yml` — runs after the archive changes on main and\n  proposes the result as a pull request. Never pushes to main.\n\n## Invariants the meta-improver must hold\n\nTwenty-three rounds of independent Codex review on PR #10 converged on these. Every one is enforced\nin code and covered by a regression test in `scripts/*_test.py`; a future change that breaks one\nshould fail the suite, not wait for a reviewer.\n\n1. **One evidence window.** Every validity comparison in a decision (candidate acceptance, weight\n   repair, rollback, the reported figure) uses the same rounds: those no later than the evidence\n   snapshot's `collected_at`. Rounds newer than the snapshot never mark a topic as \"credited by\n   reviews, never seen in the field\".\n2. **Evidence is bound to its definition.** A count is valid only for the topic name AND the keyword\n   list it was searched with. Renamed or re-mined topics, truncated searches, unsearched topics and\n   undated traces in historical epochs are _unknown_, never zero.\n3. **Evidence outlives the topic.** Refreshes keep searching every topic any recorded policy version\n   ever had, and candidates are judged against the evidence-wide counts, so a rolled-back topic\n   keeps the adverse evidence that stops it being re-mined on the same archive and snapshot. A name\n   reused with different keywords keeps every definition (older ones under `name@tag` keys), and\n   each policy version is judged on the evidence searched with its own keywords.\n4. **Measurements are pinned.** A decision refuses a measurement whose policy hash or archive digest\n   differs from what it is deciding on; topic order is part of the hash.\n5. **Rounds are stamped.** Each archived round records the policy version and hash that decided it;\n   a revision is judged only on rounds stamped with its own version and hash, and no further\n   revision is layered on one that has not yet run for `MIN_ROUNDS_TO_JUDGE` rounds. Clean reviews\n   are archived as rounds with no findings, so a policy that eliminates findings still accumulates\n   the rounds needed to judge it.\n6. **Ancestry is followed through rollbacks.** Rollback compares the current policy with every\n   unjudged ancestor, following a rollback to the ancestry of the version it restored, and rolls\n   back to the best-scoring ancestor; the recorded coverage is the restored policy's own.\n7. **No candidate regresses.** A revision is refused if it lowers coverage or validity against the\n   policy it replaces, or turns a defined validity into an undefined one; a rejected configuration\n   is not retried until the archive or the evidence has changed.\n8. **Bounded, unique mining.** At most two mined topics per revision, each backed by at least two\n   findings no other topic claims, keywords by document frequency, names never colliding with\n   existing topics, appended after existing topics so nothing already classified changes bucket.\n9. **Writes are role-specific and guarded.** The meta-improver writes only the policy and its\n   history, validates both destinations before writing either, refuses identical paths, and every\n   report/JSON side output refuses protected files, canonical evidence snapshots, and the run's own\n   inputs.\n10. **Rendered output is escaped.** Every string from the archive, history or evidence is\n    HTML-escaped at the point it enters the dashboard.\n11. **The workflow proposes, humans merge.** One superseding proposal branch, same-repository PRs\n    only, checkout pinned to the default branch, labelled with the commit actually measured,\n    machine-readable JSON written apart from the human report, re-measured after a decision.\n\n## What the field anchor is made of\n\nThe first anchor searched transcript text for the taxonomy's keywords and every hit was narration:\nthe assistant summarising review findings. Counting it made the field echo the reviews. The anchor\nis now built by `scripts/mine-trace-failures.py`, which walks every event of each working session\nthrough `traces show --json` and keeps only executions that went wrong: tool results Traces marked\nas errors, and command tools that reported a non-zero exit. Output that merely contains\nfailure-shaped text (a file displayed with `cat`, a quoted finding) never counts. Each failure is\npaired with the command that produced it, deduplicated per session by tool, command and excerpt,\nmatched independently against every topic's keywords, and written as evidence with the keyword\ndefinitions it was searched under. Failures no topic claims are the field's blind spots; when at\nleast `MIN_FIELD_BLIND_SPOTS` of them exist, `revise-improvement-policy.py --field-failures` mines\ntopics from their output the same way it mines unclassified review findings.\n\nFirst strict run over the working sessions in this folder: 96 distinct failures across 3 sessions,\nvalidity 0.55 against the review signal, 69 blind spots dominated by \"permission denied by the\nauto-mode classifier\" (28), tool input errors, and missing tools.\n\n## First real run\n\nMeasured against the archive as of round 10 with policy v1: coverage 0.61, anchor empty (no working\nsessions for this repository are indexed in Traces yet). The rule fired on coverage and proposed v2:\none mined topic covering 8 of the 11 blind-spot findings, coverage 0.61 → 0.89 (the remaining three\nare single-occurrence findings no bounded rule may claim). A second pass under v2 proposes nothing.\nWith the verifier's own review sessions counted as the anchor, validity reads 0.95: the number\nagrees with the review signal because it _is_ the review signal, which is why the default excludes\nthem.\n\nReproduce:\n\n```bash\npython3 scripts/mine-trace-failures.py --repo-dir . --save-evidence docs/rsi/trace-evidence.json\nsed -n '/^---/,$p' <(python3 scripts/measure-policy-validity.py docs/self-improvement-archive.jsonl --trace-evidence docs/rsi/trace-evidence.json) | tail -n +2 > docs/rsi/measurement.json\npython3 scripts/revise-improvement-policy.py docs/self-improvement-archive.jsonl --measurement docs/rsi/measurement.json --dry-run\npython3 scripts/render-rsi-dashboard.py docs/self-improvement-archive.jsonl --trace-evidence docs/rsi/trace-evidence.json --out docs/rsi/dashboard.html\n```\n"}

This document maps that framework onto the\nself-improvement loop this repository already runs, names the gap, and records how the gap was\nclosed.\n\n## The framework in one table\n\nThe closed improvement loop has seven parts: AI system, improver, strategy, target, verifier,\nimprovement, successor. Autonomy is measured by how many of those decisions have moved from fixed\nhuman infrastructure into the AI's own persistent state:\n\n| Level | Human keeps                        | AI internalizes        | Retained update       | Here                                                          |\n| ----- | ---------------------------------- | ---------------------- | --------------------- | ------------------------------------------------------------- |\n| L1    | objective, strategy, validation    | execution              | task outcome          | Claude Code applies a round's fix                             |\n| L2    | objective, task bounds, validation | search rules           | search strategy       | each round chooses what to try from the previous findings     |\n| L3    | environment parameters, validation | data generation        | practice curriculum   | `analyze-traces.py` / `sync-pr-traces.py` pull session traces |\n| L4    | governance rules, rollbacks        | state management       | deployed state        | `archive-round.py` + `archive-and-recommend.yml`              |\n| L5    | final oversight                    | the improver mechanism | the verifier/improver | `revise-improvement-policy.py` (this change)                  |\n\nL5's benchmark in the deck (A-Evolve-Training): the system revises its own research policy when\ndevelopment scores stop predicting external gains, then uses the revised policy to direct the next\nround.\n\nThree failure modes the design must guard against:\n\n1. **Safe inheritance** — self-modification that degrades over time. Needs transfer tests, version\n   history, automatic rollback.\n2. **Autonomy attribution** — better candidates mistaken for a better search process. Needs explicit\n   separation of AI-controlled logic from fixed infrastructure.\n3. **Reliable verification** — repeated evaluator access rewards exploitation. Needs evaluators\n   frozen per epoch and an independent ground-truth anchor.\n\n## The gap\n\nBefore this change the loop was L4. `scripts/detect-recurring-pattern.py` decided\ntarget-vs-mechanism fixes from a keyword taxonomy and a threshold that were constants in the file:\nwritten once by hand, never measured, never revised. Two consequences were visible in the real\narchive:\n\n- 11 of 28 archived findings (39%) matched no topic at all, including every finding from rounds 8 to\n  10 (archive threshold crossings, workflow concurrency, PR-creation recovery). A blind spot never\n  accumulates toward the mechanism-fix threshold, so the loop could not notice its own newest\n  recurring problem.\n- Nothing checked whether a topic the reviews kept crediting ever appeared in actual working\n  sessions.\n\n## What changed\n\n- `docs/improvement-policy.json` — the taxonomy, per-topic weights and threshold as a versioned\n  document (`version`, `parent`, `origin`). `detect-recurring-pattern.py` reads it; the old module\n  constants remain as views of the loaded policy so every caller keeps working.\n- `scripts/improvement_policy.py` — load/validate/hash the policy, version it, and the attribution\n  guard: `assert_ai_may_write` refuses any write outside the two AI-owned files.\n- `scripts/measure-policy-validity.py` — the L5 trigger. Coverage (classified / total findings) and\n  predictive validity (Spearman agreement between review-derived recurrence and Traces evidence from\n  working sessions), replayed per archive round using only what existed at that round's timestamp.\n  The verifier's own Codex review transcripts are excluded from the anchor by default; an empty\n  anchor is treated as no anchor, so nothing is discounted for failing to appear in a field nobody\n  observed.\n- `scripts/revise-improvement-policy.py` — the meta-improver. Fixed acceptance rule (constants, not\n  policy fields): revise when coverage < 0.8 or validity < 0.3; roll back when an adopted revision's\n  coverage falls below its parent's after two further rounds. Revisions are bounded: at most two\n  mined topics, each backed by at least two previously unclassified findings, keywords chosen by\n  document frequency, appended after existing topics so nothing already classified changes bucket.\n  Every version is appended to `docs/improvement-policy-history.jsonl` with a full snapshot.\n- `scripts/render-rsi-dashboard.py` — `docs/rsi/dashboard.html`, a self-contained page rendered from\n  the archive, the policy history and the evidence files: autonomy matrix, the loop with live\n  values, the trigger chart, policy lineage, the three failure-mode guards, and every finding under\n  v1 and under the current policy.\n- `.github/workflows/revise-improvement-policy.yml` — runs after the archive changes on main and\n  proposes the result as a pull request. Never pushes to main.\n\n## Invariants the meta-improver must hold\n\nTwenty-three rounds of independent Codex review on PR #10 converged on these. Every one is enforced\nin code and covered by a regression test in `scripts/*_test.py`; a future change that breaks one\nshould fail the suite, not wait for a reviewer.\n\n1. **One evidence window.** Every validity comparison in a decision (candidate acceptance, weight\n   repair, rollback, the reported figure) uses the same rounds: those no later than the evidence\n   snapshot's `collected_at`. Rounds newer than the snapshot never mark a topic as \"credited by\n   reviews, never seen in the field\".\n2. **Evidence is bound to its definition.** A count is valid only for the topic name AND the keyword\n   list it was searched with. Renamed or re-mined topics, truncated searches, unsearched topics and\n   undated traces in historical epochs are _unknown_, never zero.\n3. **Evidence outlives the topic.** Refreshes keep searching every topic any recorded policy version\n   ever had, and candidates are judged against the evidence-wide counts, so a rolled-back topic\n   keeps the adverse evidence that stops it being re-mined on the same archive and snapshot. A name\n   reused with different keywords keeps every definition (older ones under `name@tag` keys), and\n   each policy version is judged on the evidence searched with its own keywords.\n4. **Measurements are pinned.** A decision refuses a measurement whose policy hash or archive digest\n   differs from what it is deciding on; topic order is part of the hash.\n5. **Rounds are stamped.** Each archived round records the policy version and hash that decided it;\n   a revision is judged only on rounds stamped with its own version and hash, and no further\n   revision is layered on one that has not yet run for `MIN_ROUNDS_TO_JUDGE` rounds. Clean reviews\n   are archived as rounds with no findings, so a policy that eliminates findings still accumulates\n   the rounds needed to judge it.\n6. **Ancestry is followed through rollbacks.** Rollback compares the current policy with every\n   unjudged ancestor, following a rollback to the ancestry of the version it restored, and rolls\n   back to the best-scoring ancestor; the recorded coverage is the restored policy's own.\n7. **No candidate regresses.** A revision is refused if it lowers coverage or validity against the\n   policy it replaces, or turns a defined validity into an undefined one; a rejected configuration\n   is not retried until the archive or the evidence has changed.\n8. **Bounded, unique mining.** At most two mined topics per revision, each backed by at least two\n   findings no other topic claims, keywords by document frequency, names never colliding with\n   existing topics, appended after existing topics so nothing already classified changes bucket.\n9. **Writes are role-specific and guarded.** The meta-improver writes only the policy and its\n   history, validates both destinations before writing either, refuses identical paths, and every\n   report/JSON side output refuses protected files, canonical evidence snapshots, and the run's own\n   inputs.\n10. **Rendered output is escaped.** Every string from the archive, history or evidence is\n    HTML-escaped at the point it enters the dashboard.\n11. **The workflow proposes, humans merge.** One superseding proposal branch, same-repository PRs\n    only, checkout pinned to the default branch, labelled with the commit actually measured,\n    machine-readable JSON written apart from the human report, re-measured after a decision.\n\n## What the field anchor is made of\n\nThe first anchor searched transcript text for the taxonomy's keywords and every hit was narration:\nthe assistant summarising review findings. Counting it made the field echo the reviews. The anchor\nis now built by `scripts/mine-trace-failures.py`, which walks every event of each working session\nthrough `traces show --json` and keeps only executions that went wrong: tool results Traces marked\nas errors, and command tools that reported a non-zero exit. Output that merely contains\nfailure-shaped text (a file displayed with `cat`, a quoted finding) never counts. Each failure is\npaired with the command that produced it, deduplicated per session by tool, command and excerpt,\nmatched independently against every topic's keywords, and written as evidence with the keyword\ndefinitions it was searched under. Failures no topic claims are the field's blind spots; when at\nleast `MIN_FIELD_BLIND_SPOTS` of them exist, `revise-improvement-policy.py --field-failures` mines\ntopics from their output the same way it mines unclassified review findings.\n\nFirst strict run over the working sessions in this folder: 96 distinct failures across 3 sessions,\nvalidity 0.55 against the review signal, 69 blind spots dominated by \"permission denied by the\nauto-mode classifier\" (28), tool input errors, and missing tools.\n\n## First real run\n\nMeasured against the archive as of round 10 with policy v1: coverage 0.61, anchor empty (no working\nsessions for this repository are indexed in Traces yet). The rule fired on coverage and proposed v2:\none mined topic covering 8 of the 11 blind-spot findings, coverage 0.61 → 0.89 (the remaining three\nare single-occurrence findings no bounded rule may claim). A second pass under v2 proposes nothing.\nWith the verifier's own review sessions counted as the anchor, validity reads 0.95: the number\nagrees with the review signal because it _is_ the review signal, which is why the default excludes\nthem.\n\nReproduce:\n\n```bash\npython3 scripts/mine-trace-failures.py --repo-dir . --save-evidence docs/rsi/trace-evidence.json\nsed -n '/^---/,$p' <(python3 scripts/measure-policy-validity.py docs/self-improvement-archive.jsonl --trace-evidence docs/rsi/trace-evidence.json) | tail -n +2 > docs/rsi/measurement.json\npython3 scripts/revise-improvement-policy.py docs/self-improvement-archive.jsonl --measurement docs/rsi/measurement.json --dry-run\npython3 scripts/render-rsi-dashboard.py docs/self-improvement-archive.jsonl --trace-evidence docs/rsi/trace-evidence.json --out docs/rsi/dashboard.html\n```\n"}

This document maps that framework onto the\nself-improvement loop this repository already runs, names the gap, and records how the gap was\nclosed.\n\n## The framework in one table\n\nThe closed improvement loop has seven parts: AI system, improver, strategy, target, verifier,\nimprovement, successor. Autonomy is measured by how many of those decisions have moved from fixed\nhuman infrastructure into the AI's own persistent state:\n\n| Level | Human keeps                        | AI internalizes        | Retained update       | Here                                                          |\n| ----- | ---------------------------------- | ---------------------- | --------------------- | ------------------------------------------------------------- |\n| L1    | objective, strategy, validation    | execution              | task outcome          | Claude Code applies a round's fix                             |\n| L2    | objective, task bounds, validation | search rules           | search strategy       | each round chooses what to try from the previous findings     |\n| L3    | environment parameters, validation | data generation        | practice curriculum   | `analyze-traces.py` / `sync-pr-traces.py` pull session traces |\n| L4    | governance rules, rollbacks        | state management       | deployed state        | `archive-round.py` + `archive-and-recommend.yml`              |\n| L5    | final oversight                    | the improver mechanism | the verifier/improver | `revise-improvement-policy.py` (this change)                  |\n\nL5's benchmark in the deck (A-Evolve-Training): the system revises its own research policy when\ndevelopment scores stop predicting external gains, then uses the revised policy to direct the next\nround.\n\nThree failure modes the design must guard against:\n\n1. **Safe inheritance** — self-modification that degrades over time. Needs transfer tests, version\n   history, automatic rollback.\n2. **Autonomy attribution** — better candidates mistaken for a better search process. Needs explicit\n   separation of AI-controlled logic from fixed infrastructure.\n3. **Reliable verification** — repeated evaluator access rewards exploitation. Needs evaluators\n   frozen per epoch and an independent ground-truth anchor.\n\n## The gap\n\nBefore this change the loop was L4. `scripts/detect-recurring-pattern.py` decided\ntarget-vs-mechanism fixes from a keyword taxonomy and a threshold that were constants in the file:\nwritten once by hand, never measured, never revised. Two consequences were visible in the real\narchive:\n\n- 11 of 28 archived findings (39%) matched no topic at all, including every finding from rounds 8 to\n  10 (archive threshold crossings, workflow concurrency, PR-creation recovery). A blind spot never\n  accumulates toward the mechanism-fix threshold, so the loop could not notice its own newest\n  recurring problem.\n- Nothing checked whether a topic the reviews kept crediting ever appeared in actual working\n  sessions.\n\n## What changed\n\n- `docs/improvement-policy.json` — the taxonomy, per-topic weights and threshold as a versioned\n  document (`version`, `parent`, `origin`). `detect-recurring-pattern.py` reads it; the old module\n  constants remain as views of the loaded policy so every caller keeps working.\n- `scripts/improvement_policy.py` — load/validate/hash the policy, version it, and the attribution\n  guard: `assert_ai_may_write` refuses any write outside the two AI-owned files.\n- `scripts/measure-policy-validity.py` — the L5 trigger. Coverage (classified / total findings) and\n  predictive validity (Spearman agreement between review-derived recurrence and Traces evidence from\n  working sessions), replayed per archive round using only what existed at that round's timestamp.\n  The verifier's own Codex review transcripts are excluded from the anchor by default; an empty\n  anchor is treated as no anchor, so nothing is discounted for failing to appear in a field nobody\n  observed.\n- `scripts/revise-improvement-policy.py` — the meta-improver. Fixed acceptance rule (constants, not\n  policy fields): revise when coverage < 0.8 or validity < 0.3; roll back when an adopted revision's\n  coverage falls below its parent's after two further rounds. Revisions are bounded: at most two\n  mined topics, each backed by at least two previously unclassified findings, keywords chosen by\n  document frequency, appended after existing topics so nothing already classified changes bucket.\n  Every version is appended to `docs/improvement-policy-history.jsonl` with a full snapshot.\n- `scripts/render-rsi-dashboard.py` — `docs/rsi/dashboard.html`, a self-contained page rendered from\n  the archive, the policy history and the evidence files: autonomy matrix, the loop with live\n  values, the trigger chart, policy lineage, the three failure-mode guards, and every finding under\n  v1 and under the current policy.\n- `.github/workflows/revise-improvement-policy.yml` — runs after the archive changes on main and\n  proposes the result as a pull request. Never pushes to main.\n\n## Invariants the meta-improver must hold\n\nTwenty-three rounds of independent Codex review on PR #10 converged on these. Every one is enforced\nin code and covered by a regression test in `scripts/*_test.py`; a future change that breaks one\nshould fail the suite, not wait for a reviewer.\n\n1. **One evidence window.** Every validity comparison in a decision (candidate acceptance, weight\n   repair, rollback, the reported figure) uses the same rounds: those no later than the evidence\n   snapshot's `collected_at`. Rounds newer than the snapshot never mark a topic as \"credited by\n   reviews, never seen in the field\".\n2. **Evidence is bound to its definition.** A count is valid only for the topic name AND the keyword\n   list it was searched with. Renamed or re-mined topics, truncated searches, unsearched topics and\n   undated traces in historical epochs are _unknown_, never zero.\n3. **Evidence outlives the topic.** Refreshes keep searching every topic any recorded policy version\n   ever had, and candidates are judged against the evidence-wide counts, so a rolled-back topic\n   keeps the adverse evidence that stops it being re-mined on the same archive and snapshot. A name\n   reused with different keywords keeps every definition (older ones under `name@tag` keys), and\n   each policy version is judged on the evidence searched with its own keywords.\n4. **Measurements are pinned.** A decision refuses a measurement whose policy hash or archive digest\n   differs from what it is deciding on; topic order is part of the hash.\n5. **Rounds are stamped.** Each archived round records the policy version and hash that decided it;\n   a revision is judged only on rounds stamped with its own version and hash, and no further\n   revision is layered on one that has not yet run for `MIN_ROUNDS_TO_JUDGE` rounds. Clean reviews\n   are archived as rounds with no findings, so a policy that eliminates findings still accumulates\n   the rounds needed to judge it.\n6. **Ancestry is followed through rollbacks.** Rollback compares the current policy with every\n   unjudged ancestor, following a rollback to the ancestry of the version it restored, and rolls\n   back to the best-scoring ancestor; the recorded coverage is the restored policy's own.\n7. **No candidate regresses.** A revision is refused if it lowers coverage or validity against the\n   policy it replaces, or turns a defined validity into an undefined one; a rejected configuration\n   is not retried until the archive or the evidence has changed.\n8. **Bounded, unique mining.** At most two mined topics per revision, each backed by at least two\n   findings no other topic claims, keywords by document frequency, names never colliding with\n   existing topics, appended after existing topics so nothing already classified changes bucket.\n9. **Writes are role-specific and guarded.** The meta-improver writes only the policy and its\n   history, validates both destinations before writing either, refuses identical paths, and every\n   report/JSON side output refuses protected files, canonical evidence snapshots, and the run's own\n   inputs.\n10. **Rendered output is escaped.** Every string from the archive, history or evidence is\n    HTML-escaped at the point it enters the dashboard.\n11. **The workflow proposes, humans merge.** One superseding proposal branch, same-repository PRs\n    only, checkout pinned to the default branch, labelled with the commit actually measured,\n    machine-readable JSON written apart from the human report, re-measured after a decision.\n\n## What the field anchor is made of\n\nThe first anchor searched transcript text for the taxonomy's keywords and every hit was narration:\nthe assistant summarising review findings. Counting it made the field echo the reviews. The anchor\nis now built by `scripts/mine-trace-failures.py`, which walks every event of each working session\nthrough `traces show --json` and keeps only executions that went wrong: tool results Traces marked\nas errors, and command tools that reported a non-zero exit. Output that merely contains\nfailure-shaped text (a file displayed with `cat`, a quoted finding) never counts. Each failure is\npaired with the command that produced it, deduplicated per session by tool, command and excerpt,\nmatched independently against every topic's keywords, and written as evidence with the keyword\ndefinitions it was searched under. Failures no topic claims are the field's blind spots; when at\nleast `MIN_FIELD_BLIND_SPOTS` of them exist, `revise-improvement-policy.py --field-failures` mines\ntopics from their output the same way it mines unclassified review findings.\n\nFirst strict run over the working sessions in this folder: 96 distinct failures across 3 sessions,\nvalidity 0.55 against the review signal, 69 blind spots dominated by \"permission denied by the\nauto-mode classifier\" (28), tool input errors, and missing tools.\n\n## First real run\n\nMeasured against the archive as of round 10 with policy v1: coverage 0.61, anchor empty (no working\nsessions for this repository are indexed in Traces yet). The rule fired on coverage and proposed v2:\none mined topic covering 8 of the 11 blind-spot findings, coverage 0.61 → 0.89 (the remaining three\nare single-occurrence findings no bounded rule may claim). A second pass under v2 proposes nothing.\nWith the verifier's own review sessions counted as the anchor, validity reads 0.95: the number\nagrees with the review signal because it _is_ the review signal, which is why the default excludes\nthem.\n\nReproduce:\n\n```bash\npython3 scripts/mine-trace-failures.py --repo-dir . --save-evidence docs/rsi/trace-evidence.json\nsed -n '/^---/,$p' <(python3 scripts/measure-policy-validity.py docs/self-improvement-archive.jsonl --trace-evidence docs/rsi/trace-evidence.json) | tail -n +2 > docs/rsi/measurement.json\npython3 scripts/revise-improvement-policy.py docs/self-improvement-archive.jsonl --measurement docs/rsi/measurement.json --dry-run\npython3 scripts/render-rsi-dashboard.py docs/self-improvement-archive.jsonl --trace-evidence docs/rsi/trace-evidence.json --out docs/rsi/dashboard.html\n```\n"}

I reproduced two ways around the wait gate: changing only policy metadata, and restoring v1 through a rollback.

I’m checking the remaining ancestry and write-guard cases before finalizing the findings.

[P1] Policy metadata can disable evaluation gates. scripts/improvement_policy.py:93 and scripts/revise-improvement-policy.py:617
Validation does not check origin, ancestry, or consistency with history, while rollback and waiting depend on those fields. The policy hash excludes them.
Reproduction: Using identical archive, history, measurement, and v2 policy contents, changed only origin from "revision" to "init". The actual revision CLI returned exit 0 in both cases, but changed its decision from none to revise with zero qualifying rounds. An AI editing only its policy can bypass invariant 5 and rollback enforcement.
[P1] A topic name containing @ permits acceptance of a validity regression. scripts/revise-improvement-policy.py:452
Policy validation allows @, and measurement correctly resolves an exact matching definition. However, candidate_anchor() splits evidence names at @ and silently excludes that policy topic from acceptance comparisons.
Reproduction: Renamed shell-semantics to shell-semantics@custom in the four-topic test fixture and its evidence definitions; used weights [0.5, 1, 1, 1] and field counts [1, 2, 1, 0]. The decision accepted restoring the first weight, reporting validity 1.0. Remeasuring the accepted policy showed validity falling 0.5 → 0.3333. This breaks invariants 3 and 7.
[P2] Truncated failure excerpts become authoritative zero evidence. scripts/mine-trace-failures.py:199 and scripts/mine-trace-failures.py:245
Topic matching searches only the shortened command and excerpt. Discarded output is neither searched nor marked truncated, so relevant failures can become evidence of absence.
Reproduction: Supplied a status: "error" result containing a traceback header, a 200-character frame line, and ValueError: secret exposed. Mining and evidence construction returned {'secrets': 0, 'tracebacks': 1} with truncated: []. A real secret-related failure therefore appears uncorroborated. This breaks invariant 2; the tests cover listing truncation, not this content truncation.
[P2] Rolling back to v1 skips the waiting period. scripts/revise-improvement-policy.py:693
The wait gate requires base_version is not None. A rollback restoring v1 has no remaining ancestor because judged_from() returns v1’s parent, None.
Reproduction: Constructed v3 through new_version(..., origin="rollback", restored_version=1) with complete history and two unclassified archive findings. rounds_under() returned 0, but decide() returned revise. This breaks invariant 5 without malformed metadata.
[P2] Ancestor comparisons check coverage only against the immediate parent. scripts/revise-improvement-policy.py:631
The ancestor loop selects by validity alone. Without an anchor, a coverage regression inherited from a grandparent is invisible when current and parent coverage are equal.
Reproduction: Built a valid lineage where v1 recognizes quartz, v2 removes that topic, and v3 adds an unrelated topic. Two rounds stamped with v3 gave coverage 1.0, 0.0, 0.0 respectively. Although ancestry traversal returned [2, 1], the decision was revise, not rollback to v1. This breaks invariant 6; the existing multi-ancestor regression test exercises validity only.
[P2] Hard-linked outputs bypass input protection and overwrite the archive. scripts/improvement_policy.py:253
Comparing resolved paths detects symlinks but does not detect different paths sharing an inode.
Reproduction: Created temporary archive.jsonl and a hard link named report.json, then ran the measurement CLI with the archive as input and --out-json report.json. It returned 0 and replaced the archive contents with measurement JSON. This breaks invariant 9. The reproduction touched only temporary files.

Verification

Reviewed committed HEAD b024ff8f4c4e7f9356ea31258a8d954063a15675 against origin/main.

Ran git diff origin/main...HEAD, followed by focused file/diff reads.
Ran python3 -m pytest scripts/ -q -p no:cacheprovider: 147 passed.
Ran ruff check scripts/: All checks passed!
Ran targeted python3 - <<'PY' ... PY reproductions for all six findings. Exact consolidated reproductions: l5-review-repros.py.
Concurrent working-tree edits appeared during review. Repeated the tests, Ruff check, and all six reproductions against an isolated git archive HEAD snapshot: 147 passed, Ruff passed, and all six findings reproduced. Uncommitted changes were excluded.

Invariant coverage: Findings above identify failures in 2, 3, 5, 6, 7, and 9. I found no additional defect in 1 (evidence-window alignment), 4 (literal policy-hash/archive-digest checks), 8 (bounded, unique mining), 10 (HTML escaping), or 11 (proposal workflow, inspected statically). I found no additional issue in clean-round stamping, ordinary definition variants, explicit truncation/undated-evidence handling, or role-specific destination checks. Workflow execution and live Traces behavior were not tested.

Verdict

The committed branch does not hold its stated invariants. Passing tests miss reproducible evaluation bypasses, acceptance of a validity regression, and archive corruption through an output alias.
