Reproduce

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 B — the GitHub Actions workflows on this branch: .github/workflows/codex-review.yml, revise-improvement-policy.yml, archive-and-recommend.yml (and any other workflow the diff touches). Check: trust boundaries (what a PR author can influence), where artifacts live, the codex-review-status stamp and whether the review text can forge it, secret handling, the proposal-branch/PR flow, idempotency, whether the archive round SHA logic can drop or duplicate rounds, whether an attacker PR could make the meta-improver write outside its allowed files, and whether the workflows call the scripts with flags the scripts actually define (check every python3 scripts/... invocation against the script's argparse). You cannot run Actions; reason from the YAML and reproduce script invocations locally where possible.

I’ll review the full branch diff, focus on workflow trust boundaries and script invocations, and run the requested checks plus targeted reproductions.

The archive\n    28\t# update is proposed as a PR instead, same as every other change in this\n    29\t# repo's history.\n    30\t# The same Codex review also found that filtering PR comments by their\n    31\t# opening text alone lets any PR commenter forge a fake \"Codex independent\n    32\t# review\" comment; this workflow now requires both the posting account to\n    33\t# be github-actions[bot] AND the comment to carry the exact head-SHA marker\n    34\t# .github/workflows/codex-review.yml embeds, binding the analyzed comment\n    35\t# to the specific commit this workflow_run was triggered by.\n    36\t#\n    37\t# Runs after \"Codex Review\" (.github/workflows/codex-review.yml) completes.\n    38\t# Uses `workflow_run`, not `pull_request`: workflow_run always executes the\n    39\t# workflow file AND checks out source from the repository's default\n    40\t# branch, never the PR's own commits -- so, unlike codex-review.yml, this\n    41\t# workflow has no PR-authored-script trust boundary to manage. It requests\n    42\t# no secrets: everything it reads (the posted review comment, the archive\n    43\t# file) is already-redacted, already-public PR content.\n    44\t# Second real finding from that same Codex review, on a live re-review of\n    45\t# this file: each run only compares the archive against ITS OWN new round.\n    46\t# If two separate PRs are each mid-flight proposing an archive-round PR\n    47\t# (neither merged yet), each run sees only its own addition and neither\n    48\t# reports a crossing — even if merging both together would cross it. The\n    49\t# `push` trigger below closes that: once any archive-round PR actually\n    50\t# merges into main, this re-evaluates the FULL merged archive from\n    51\t# scratch and opens an issue for any topic at/above threshold that\n    52\t# doesn't already have one open.

That\n     8\t# \"when to act\" decision was a human/agent judgment call made by reading\n     9\t# the archive. This workflow makes it automatic, but ONLY for two\n    10\t# deliberately bounded actions: proposing an append-only audit entry to the\n    11\t# archive AS A PULL REQUEST (never a direct push — a human still merges\n    12\t# it), and opening a tracking issue. It never merges, deploys, or touches\n    13\t# secrets, and requests no secrets.\n    14\t#\n    15\t# History: the first draft of this workflow computed \"newly crossed\n    16\t# threshold\" purely in memory against the static on-disk archive, never\n    17\t# persisting the round. Codex's review of that draft found the real\n    18\t# consequence: two separate PRs that each contribute one finding on the\n    19\t# same topic never combine, because each is compared against the same\n    20\t# unchanged baseline in isolation -- evidence never actually accumulates\n    21\t# across PRs. scripts/archive-round.py fixes this by appending each\n    22\t# processed round to the archive, tagged with the PR commit SHA it came\n    23\t# from. The first version of this fix pushed that change directly to the\n    24\t# default branch; Claude Code's own auto-mode classifier correctly refused\n    25\t# that (\"Merge Without Review\") -- an automated direct push to the default\n    26\t# branch is exactly the review-bypass pattern this whole hardening effort\n    27\t# has otherwise never allowed itself, even for \"just data\". The archive\n    28\t# update is proposed as a PR instead, same as every other change in this\n    29\t# repo's history.\n    30\t# The same Codex review also found that filtering PR comments by their\n    31\t# opening text alone lets any PR commenter forge a fake \"Codex independent\n    32\t# review\" comment; this workflow now requires both the posting account to\n    33\t# be github-actions[bot] AND the comment to carry the exact head-SHA marker\n    34\t# .github/workflows/codex-review.yml embeds, binding the analyzed comment\n    35\t# to the specific commit this workflow_run was triggered by.\n    36\t#\n    37\t# Runs after \"Codex Review\" (.github/workflows/codex-review.yml) completes.\n    38\t# Uses `workflow_run`, not `pull_request`: workflow_run always executes the\n    39\t# workflow file AND checks out source from the repository's default\n    40\t# branch, never the PR's own commits -- so, unlike codex-review.yml, this\n    41\t# workflow has no PR-authored-script trust boundary to manage. It requests\n    42\t# no secrets: everything it reads (the posted review comment, the archive\n    43\t# file) is already-redacted, already-public PR content.\n    44\t# Second real finding from that same Codex review, on a live re-review of\n    45\t# this file: each run only compares the archive against ITS OWN new round.\n    46\t# If two separate PRs are each mid-flight proposing an archive-round PR\n    47\t# (neither merged yet), each run sees only its own addition and neither\n    48\t# reports a crossing — even if merging both together would cross it. The\n    49\t# `push` trigger below closes that: once any archive-round PR actually\n    50\t# merges into main, this re-evaluates the FULL merged archive from\n    51\t# scratch and opens an issue for any topic at/above threshold that\n    52\t# doesn't already have one open.

Runs Codex (a model with no stake in this\n# repo's prior conclusions) against every PR diff and posts its findings as a\n# PR comment. This job is advisory: it reports [P1]/[P2] findings and fails\n# the check on a [P1], but it does not itself block merge unless branch\n# protection is separately configured to require it — that's a deliberate,\n# explicit decision left to the repo owner, not made here.\n#\n# Requires ONE of:\n#   - CODEX_AUTH_JSON: the contents of a `codex login`-produced ~/.codex/auth.json\n#     (ChatGPT-subscription auth — ties usage to that account's plan, not a\n#     separate API budget; see docs/production-hardening-backlog.md item #4)\n#   - CODEX_API_KEY / OPENAI_API_KEY: a standard API key\n# Without one of these, this job reports that plainly and exits — it never\n# silently no-ops as if review happened.

This workflow redacts any\n# verbatim occurrence of the configured secret value from the posted comment\n# and job logs as a concrete backstop, but that is a partial mitigation, not\n# full isolation (a sufficiently reworded/re-encoded exfiltration attempt\n# could still evade a literal-substring redaction). Real isolation would mean\n# authenticating through a proxy that never hands the credential itself to\n# the process reading untrusted diff content — not implemented here.

GITHUB_TOKEN - GitHub Docs (https://docs.github.com/en/actions/concepts/security/github_token)
citeturn0search0 [wordlim: 200] Crawled: yesterday;   * `pull_request` events with the `opened`, `synchronize`, or `reopened` activity types: when a workflow using `GITHUB_TOKEN` creates or updates a pull request, the resulting `pull_request` event creates workflow runs in an approval-required state. ... If you need workflow runs from workflow-created pull requests to execute without requiring approval, use a GitHub App installation access token or a personal access token instead of `GITHUB_TOKEN` when creating or updating the pull request.

# GITHUB_TOKEN

Learn what `GITHUB_TOKEN` is, how it works, and why it matters for secure automation in GitHub Actions workflows.

## In this article

## About the `GITHUB_TOKEN`

At the start of each workflow job, GitHub automatically creates a unique `GITHUB_TOKEN` secret to use in your workflow. You can use the `GITHUB_TOKEN` to authenticate in the workflow job.

When you enable GitHub Actions, GitHub installs a GitHub App on your repository. The `GITHUB_TOKEN` secret is a GitHub App installation access token. You can use the installation access token to authenticate on behalf of the GitHub App installed on your repository. The token's permissions are limited to the repository that contains your workflow. For more information, see Workflow syntax for GitHub Actions.

Before each job begins, GitHub fetches an installation access token for the job. The `GITHUB_TOKEN` expires when the job finishes or after its effective maximum lifetime.

The effective maximum lifetime of the token depends on the type of runner:

  * GitHub-hosted runners The maximum job execution time is 6 hours, so the `GITHUB_TOKEN` can live for a maximum of 6 hours.
  * Self-hosted runners The maximum job execution time is 5 days. However, because the `GITHUB_TOKEN` is an installation access token, it can only be refreshed for up to 24 hours. If your job runs longer than 24 hours, use a personal access token or other authentication method instead.

The token is also available in the `github.token` context. For more information, see Contexts reference.

## When `GITHUB_TOKEN` triggers workflow runs

When you use the repository's `GITHUB_TOKEN` to perform tasks, events triggered by the `GITHUB_TOKEN` will not create a new workflow run, with the following exceptions:

  * `workflow_dispatch` and `repository_dispatch` events always create workflow runs.
  * `pull_request` events with the `opened`, `synchronize`, or `reopened` activity types: when a workflow using `GITHUB_TOKEN` creates or updates a pull request, the resulting `pull_request` event creates workflow runs in an approval-required state. The pull request displays a banner in the merge box, and a user with write access to the repository can start the runs by selecting Approve workflows to run. Other `pull_request` activity types (such as `labeled`, `edited`, or `closed`) do not create workflow runs. This prevents recursive workflow runs while still allowing CI workflows to run on pull requests created by automation. For more information about approving workflow runs, see Approving workflow runs from forks.

For all other events, this behavior prevents you from accidentally creating recursive workflow runs. For example, if a workflow run pushes code using the repository's `GITHUB_TOKEN`, a new workflow will not run even when the repository contains a workflow configured to run when `push` events occur.

Note

If you need workflow runs from workflow-created pull requests to execute without requiring approval, use a GitHub App installation access token or a personal access token instead of `GITHUB_TOKEN` when creating or updating the pull request.

Commits pushed by a GitHub Actions workflow that uses the `GITHUB_TOKEN` do not trigger a GitHub Pages build.

# Triggering a workflow

How to automatically trigger GitHub Actions workflows

## Prerequisites

To learn more about workflows and triggering workflows, see Workflows.

## Triggering a workflow from a workflow

When you use the repository's `GITHUB_TOKEN` to perform tasks, events triggered by the `GITHUB_TOKEN` will not create a new workflow run, with the following exceptions:

  * `workflow_dispatch` and `repository_dispatch` events always create workflow runs.
  * `pull_request` events with the `opened`, `synchronize`, or `reopened` activity types: when a workflow using `GITHUB_TOKEN` creates or updates a pull request, the resulting `pull_request` event creates workflow runs in an approval-required state. The pull request displays a banner in the merge box, and a user with write access to the repository can start the runs by selecting Approve workflows to run. Other `pull_request` activity types (such as `labeled`, `edited`, or `closed`) do not create workflow runs. This prevents recursive workflow runs while still allowing CI workflows to run on pull requests created by automation. For more information about approving workflow runs, see Approving workflow runs from forks.

For all other events, this behavior prevents you from accidentally creating recursive workflow runs. For example, if a workflow run pushes code using the repository's `GITHUB_TOKEN`, a new workflow will not run even when the repository contains a workflow configured to run when `push` events occur. For more information, see Use GITHUB_TOKEN for authentication in workflows.

If you do want to trigger a workflow from within a workflow run, you can use a GitHub App installation access token or a personal access token instead of `GITHUB_TOKEN` to trigger events that require a token. Using one of these alternatives also lets `pull_request` workflows run automatically (without the approval prompt described above) when the pull request is created or updated by automation.

If you use a GitHub App, you'll need to create a GitHub App and store the app ID and private key as secrets. For more information, see Making authenticated API requests with a GitHub App in a GitHub Actions workflow. --------------------------------------------------------------------------------
Events that trigger workflows - GitHub Docs (https://docs.github.com/en/actions/reference/workflows-and-actions/events-that-trigger-workflows)
citeturn0search2 [wordlim: 200] Crawled: yesterday;   * When a pull request is created or updated by a workflow using `GITHUB_TOKEN`, `pull_request` events with the `opened`, `synchronize`, or `reopened` activity types create workflow runs that require approval. ... For open, mergeable pull requests, workflows triggered by the `pull_request` event set `GITHUB_REF` to the merge branch.
For more information, see `pull_request_target`.
  * The `pull_request` webhook event payload is empty for merged pull requests and pull requests that come from forked repositories.
  * When a pull request is created or updated by a workflow using `GITHUB_TOKEN`, `pull_request` events with the `opened`, `synchronize`, or `reopened` activity types create workflow runs that require approval. A user with write access to the repository can approve these runs from the pull request page. With the exception of `workflow_dispatch` and `repository_dispatch`, other `GITHUB_TOKEN`-triggered events do not create workflow runs at all.
  * The value of `GITHUB_REF` varies for a closed pull request depending on whether the pull request has been merged or not. If a pull request was closed but not merged, it will be `refs/pull/PULL_REQUEST_NUMBER/merge`. If a pull request was closed as a result of being merged, it will be the fully qualified `ref` of the branch it was merged into, for example `/refs/heads/main`.

Runs your workflow when activity on a pull request in the workflow's repository occurs. For example, if no activity types are specified, the workflow runs when a pull request is opened or reopened or when the head branch of the pull request is updated. For activity related to pull request reviews, pull request review comments, or pull request comments, use the `pull_request_review`, `pull_request_review_comment`, or `issue_comment` events instead. For information about the pull request APIs, see Pull requests in the GraphQL API documentation or REST API endpoints for pull requests.

Note that `GITHUB_SHA` for this event is the last merge commit of the pull request merge branch. If you want to get the commit ID for the last commit to the head branch of the pull request, use `github.event.pull_request.head.sha` instead. For more information about merge branches, see Pull requests.

If you need workflow runs from workflow-created pull requests to execute without requiring approval, use a GitHub App installation access token or a personal access token instead of `GITHUB_TOKEN` when creating or updating the pull request.

# GITHUB_TOKEN

Learn what `GITHUB_TOKEN` is, how it works, and why it matters for secure automation in GitHub Actions workflows.

## In this article

## About the `GITHUB_TOKEN`

At the start of each workflow job, GitHub automatically creates a unique `GITHUB_TOKEN` secret to use in your workflow. You can use the `GITHUB_TOKEN` to authenticate in the workflow job.

When you enable GitHub Actions, GitHub installs a GitHub App on your repository. The `GITHUB_TOKEN` secret is a GitHub App installation access token. You can use the installation access token to authenticate on behalf of the GitHub App installed on your repository. The token's permissions are limited to the repository that contains your workflow. For more information, see Workflow syntax for GitHub Actions.

Before each job begins, GitHub fetches an installation access token for the job. The `GITHUB_TOKEN` expires when the job finishes or after its effective maximum lifetime.

The effective maximum lifetime of the token depends on the type of runner:

  * GitHub-hosted runners The maximum job execution time is 6 hours, so the `GITHUB_TOKEN` can live for a maximum of 6 hours.
  * Self-hosted runners The maximum job execution time is 5 days. However, because the `GITHUB_TOKEN` is an installation access token, it can only be refreshed for up to 24 hours. If your job runs longer than 24 hours, use a personal access token or other authentication method instead.

The token is also available in the `github.token` context. For more information, see Contexts reference.

## When `GITHUB_TOKEN` triggers workflow runs

When you use the repository's `GITHUB_TOKEN` to perform tasks, events triggered by the `GITHUB_TOKEN` will not create a new workflow run, with the following exceptions:

  * `workflow_dispatch` and `repository_dispatch` events always create workflow runs.
  * `pull_request` events with the `opened`, `synchronize`, or `reopened` activity types: when a workflow using `GITHUB_TOKEN` creates or updates a pull request, the resulting `pull_request` event creates workflow runs in an approval-required state. The pull request displays a banner in the merge box, and a user with write access to the repository can start the runs by selecting Approve workflows to run. Other `pull_request` activity types (such as `labeled`, `edited`, or `closed`) do not create workflow runs. This prevents recursive workflow runs while still allowing CI workflows to run on pull requests created by automation. For more information about approving workflow runs, see Approving workflow runs from forks.

For all other events, this behavior prevents you from accidentally creating recursive workflow runs. For example, if a workflow run pushes code using the repository's `GITHUB_TOKEN`, a new workflow will not run even when the repository contains a workflow configured to run when `push` events occur.

Note

If you need workflow runs from workflow-created pull requests to execute without requiring approval, use a GitHub App installation access token or a personal access token instead of `GITHUB_TOKEN` when creating or updating the pull request.

Commits pushed by a GitHub Actions workflow that uses the `GITHUB_TOKEN` do not trigger a GitHub Pages build.

# Triggering a workflow

How to automatically trigger GitHub Actions workflows

## Prerequisites

To learn more about workflows and triggering workflows, see Workflows.

## Triggering a workflow from a workflow

When you use the repository's `GITHUB_TOKEN` to perform tasks, events triggered by the `GITHUB_TOKEN` will not create a new workflow run, with the following exceptions:

  * `workflow_dispatch` and `repository_dispatch` events always create workflow runs.
  * `pull_request` events with the `opened`, `synchronize`, or `reopened` activity types: when a workflow using `GITHUB_TOKEN` creates or updates a pull request, the resulting `pull_request` event creates workflow runs in an approval-required state. The pull request displays a banner in the merge box, and a user with write access to the repository can start the runs by selecting Approve workflows to run. Other `pull_request` activity types (such as `labeled`, `edited`, or `closed`) do not create workflow runs. This prevents recursive workflow runs while still allowing CI workflows to run on pull requests created by automation. For more information about approving workflow runs, see Approving workflow runs from forks.

For all other events, this behavior prevents you from accidentally creating recursive workflow runs. For example, if a workflow run pushes code using the repository's `GITHUB_TOKEN`, a new workflow will not run even when the repository contains a workflow configured to run when `push` events occur. For more information, see Use GITHUB_TOKEN for authentication in workflows.

If you do want to trigger a workflow from within a workflow run, you can use a GitHub App installation access token or a personal access token instead of `GITHUB_TOKEN` to trigger events that require a token. Using one of these alternatives also lets `pull_request` workflows run automatically (without the approval prompt described above) when the pull request is created or updated by automation.

If you use a GitHub App, you'll need to create a GitHub App and store the app ID and private key as secrets. For more information, see Making authenticated API requests with a GitHub App in a GitHub Actions workflow. --------------------------------------------------------------------------------
Events that trigger workflows - GitHub Docs (https://docs.github.com/en/actions/reference/workflows-and-actions/events-that-trigger-workflows)
citeturn0search2 [wordlim: 200] Crawled: yesterday;   * When a pull request is created or updated by a workflow using `GITHUB_TOKEN`, `pull_request` events with the `opened`, `synchronize`, or `reopened` activity types create workflow runs that require approval. ... For open, mergeable pull requests, workflows triggered by the `pull_request` event set `GITHUB_REF` to the merge branch.
For more information, see `pull_request_target`.
  * The `pull_request` webhook event payload is empty for merged pull requests and pull requests that come from forked repositories.
  * When a pull request is created or updated by a workflow using `GITHUB_TOKEN`, `pull_request` events with the `opened`, `synchronize`, or `reopened` activity types create workflow runs that require approval. A user with write access to the repository can approve these runs from the pull request page. With the exception of `workflow_dispatch` and `repository_dispatch`, other `GITHUB_TOKEN`-triggered events do not create workflow runs at all.
  * The value of `GITHUB_REF` varies for a closed pull request depending on whether the pull request has been merged or not. If a pull request was closed but not merged, it will be `refs/pull/PULL_REQUEST_NUMBER/merge`. If a pull request was closed as a result of being merged, it will be the fully qualified `ref` of the branch it was merged into, for example `/refs/heads/main`.

Runs your workflow when activity on a pull request in the workflow's repository occurs. For example, if no activity types are specified, the workflow runs when a pull request is opened or reopened or when the head branch of the pull request is updated. For activity related to pull request reviews, pull request review comments, or pull request comments, use the `pull_request_review`, `pull_request_review_comment`, or `issue_comment` events instead. For information about the pull request APIs, see Pull requests in the GraphQL API documentation or REST API endpoints for pull requests.

Note that `GITHUB_SHA` for this event is the last merge commit of the pull request merge branch. If you want to get the commit ID for the last commit to the head branch of the pull request, use `github.event.pull_request.head.sha` instead. For more information about merge branches, see Pull requests.

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 v…111 tokens truncated…  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```\n335:    parser.add_argument(\"--repo-dir\", required=True)\n336:    parser.add_argument(\"--agents\", default=\",\".join(measure_mod.DEFAULT_ANCHOR_AGENTS))\n337:    parser.add_argument(\"--policy\", default=None)\n338:    parser.add_argument(\"--history\", default=str(policy_mod.HISTORY_PATH))\n339:    parser.add_argument(\"--out-json\", default=None)\n340:    parser.add_argument(\"--save-evidence\", default=None)\n341:    parser.add_argument(\"--traces-bin\", default=\"traces\")\n342:    parser.add_argument(\"--limit\", type=int, default=200)\n"}

The reproductions confirmed two archive-integrity problems: review text can supply a SHA marker that makes a newer comment match an older run, and two distinct review SHAs can collapse into one L5 round. The status-marker sanitization itself worked. All workflow script invocations I exercised succeeded in an isolated copy.

GitHub’s current documentation says bot-created PRs require approval before their review workflows run; I’m not treating that approval gate as a defect.

[P1] Review text can forge the SHA binding and corrupt archived evidence.
Files: codex-review.yml:346, archive-and-recommend.yml:134.

The posting step sanitizes codex-review-status, but leaves codex-review-sha untouched. The archive workflow accepts a matching SHA marker anywhere in a bot-authored comment and selects the latest match.

If review B quotes or reproduces  while A’s archive job is pending, that job can select B’s findings—or B’s clean result—as evidence for A. The archive then consumes A’s SHA, preventing correction on retry.

Reproduction: Ran the actual JavaScript sanitizer and equivalent selection predicate through Node, using a B comment containing A’s marker. Observed wrongShaMatches: 1. Passed the resulting comment to archive-round.py: it exited 0 and recorded source_sha: aaaa… with empty findings. The forged status marker was correctly neutralized; the SHA marker survived.

Bind comments to trusted run metadata, or validate one authoritative footer and sanitize SHA markers in review text too.
[P2] Concurrent archive proposals collapse distinct reviews into one evaluation round.
Files: archive-and-recommend.yml:158, measure-policy-validity.py:109, revise-improvement-policy.py:538.

Two archive proposals created before either merges compute the same next integer round from main. Keeping both appended records when merging does not resolve that collision. The new L5 measurement combines them by round number, and rounds_under() counts them once despite their different SHAs. This delays evaluation/rollback and combines separate evidence epochs.

Reproduction: Called build_round_entry() twice against the checked-in archive with distinct SHAs. Both received round 11. Combining both records increased the measured round count by 1, and rounds_under([a, b], policy) returned 1.

Use a stable unique review identity for automated rounds, retaining separate handling for legacy placeholder/result pairs.

Verification

git diff origin/main...HEAD — captured the entire branch diff; inspected all three changed workflows and their script interfaces.
python3 -m pytest scripts/ -q -p no:cacheprovider — 147 passed.
ruff check scripts/ — All checks passed.
Targeted python3 - <<'PY' … PY reproductions — confirmed both findings. One initial attempt referenced a nonexistent helper; corrected to rounds_in_order() and reran successfully.
In an isolated repository copy, exercised archive, detection, measurement with/without trace evidence, revision, and dashboard invocations — all exited 0. No undefined workflow flags found, including the documented mining invocation.
No additional confirmed finding in status-stamp sanitization, artifact placement, secret handling, proposal branch replacement, or policy-driven writes outside allowed files. This does not establish runtime sandbox isolation; Actions was not run.
Documentation fetch through Jina failed DNS resolution; browser fallback succeeded. GitHub currently places bot-created PR workflows behind an approval gate; that is not reported as a defect. GitHub documentation

Verdict

No—the branch as a whole does not hold its stated invariants: workflow evidence can be bound to the wrong SHA, and distinct reviews can collapse into one L5 evaluation round.
