From 18e0485bf50fd63ef4079c005f2cb47c0339d4f2 Mon Sep 17 00:00:00 2001 From: Kyle Sexton <153232337+kyle-sexton@users.noreply.github.com> Date: Wed, 28 Oct 2026 14:55:29 -0400 Subject: [PATCH 01/23] feat(pr-pipeline): hold credentialed workflows and workflow privilege gains for a person Every workflow whose token can write, that names a secret other than GITHUB_TOKEN, or that mints a lane token, and the review workflows themselves, is now a `gate` floor path held for a person. A workflow change that gains a write scope (or drops a permissions block onto the repository default) holds as `permission-widening-review`, and one that adds a pull_request_target or workflow_run trigger as `privileged-trigger-review`; both are person codes no cost decision clears. A secrets reference is also read from the head text, so a workflow with no patch is not skipped.

For a pull request that changes a lane source it reviews the head's diff as data, with each lane's criteria copied from main, on a read-only token and a Read-only model leg, and uploads each lane's verdict as pr-review-main---. It posts nothing; the merge gate binds the lanes on that artifact through the run's record.

The verdict artifacts keep the repository maximum, so an expired verdict with findings cannot lower the count a later clean review of the same tree leaves.

Job-token writers leave the gate; their widened permissions, privileged triggers, secrets and model legs still hold by patch. pr-require-checks.yml stays enforcement. The gate holds 17 of 34 workflows, down from 27.

The workflow now splits the diff into parts of at most 15000 bytes and 1000 lines, refuses a longer line, lists the parts in the prompt, and write-verdict.mjs writes a verdict only when the run read each part with one non-failing Read and no offset or limit. The text-only workflow reader also reads the keys under a block `on:`, so a mapping-form `issues:` trigger holds without PyYAML.

Read a non-job secret as the union of the reference forms and any `secrets` context in a `${{ }}` span that may hold a lone `}`, so `format('{0}', secrets.X)`, `'}' || secrets.X`, the multi-line form and `if: toJSON(secrets)` gate again. The gated set stays 17 of 34. - Hold `**/.claude/**` and `**/.claude-lane/**` whole in place of the per-file globs (owner decision Q11). sync-hold-floor.py refuses a glob whose `*` bash would let cross `/`, and a test runs the same paths through the Python, mjs and bash matchers. - Count a `pr-review-main: ` record only when the github-actions app posted it.

A workflow whose token has `actions: write` (block, flow, quoted or write-all) can dispatch the gated credentialed workflows, so it is gated too. sync-hold-floor.py regenerates the copies: 23 gated workflows. long-line-review now fires only when needs_main_review, the predicate bind() uses, says the main-run review binds the pull request. RiskInput carries the base SHA, and the head text with_contents read stands in for bind()'s head_file, so a read-only workflow's long line no longer holds.
