GitHub starts no workflow run for events created with that credential, so the moved head collected no current-head required checks and the PR stayed permanently BLOCKED with a github-actions[bot] merge commit that no later scheduler run could repair, because the branch was no longer behind. The scheduler now waits with head_mutation_credential_upgrade guidance naming PR_REVIEW_MERGE_TOKEN, OPENCODE_APPROVE_TOKEN, and the OpenCode app token exchange. - Parsed `opencode.jsonc` as JSONC (stripping `//` and `/* */` comments outside string literals) in the reasoning-effort guard and its contract tests, instead of raw `json.loads`, which rejected the file the moment it carried its first explanatory comment (added for the `contextual-orchestrator` provider block) with `Expecting property name enclosed in double quotes`. Comment markers inside string values, such as the `$schema` URL, are left untouched. - Download the pinned `uv` 0.12.1 exporter from the official GitHub Releases URL instead of `releases.astral.sh`, which now returns HTTP 403 and blocks org-wide OpenCode `coverage-evidence`. The SHA-256 pin is unchanged. The opener may follow one hop onto `release-assets.githubusercontent.com` or `objects.githubusercontent.com` and still rejects every other host, userinfo, non-HTTPS scheme, and nondefault port (ContextualWisdomLab/.github#1109). - Compared the trusted `uv` executable's post-install `--version` output against the real GitHub Releases build's full string, `uv 0.12.1 (x86_64-unknown-linux-gnu)`, instead of the bare `uv 0.12.1` the prior check required; the genuine release binary always prints the target triple, so every installation was failing the pin check immediately after the archive download itself was fixed (ContextualWisdomLab/.github#1109). diff --git a/docs/pr-review-and-merge-procedure.md b/docs/pr-review-and-merge-procedure.md index 87607fb99..feba6a052 100644 --- a/docs/pr-review-and-merge-procedure.md +++ b/docs/pr-review-and-merge-procedure.md @@ -99,6 +99,25 @@ conflict markers with OpenCode, then push the resolved head.

GitHub starts no workflow run for events created with that credential, so the moved head collected no current-head required checks and the PR stayed permanently `BLOCKED` with a `github-actions[bot]` merge commit that no later scheduler run could repair, because the branch was no longer behind. The scheduler now waits with `head_mutation_credential_upgrade` guidance naming `PR_REVIEW_MERGE_TOKEN`, `OPENCODE_APPROVE_TOKEN`, and the OpenCode app token exchange. - Parsed `opencode.jsonc` as JSONC (stripping `//` and `/* */` comments outside string literals) in the reasoning-effort guard and its contract tests, instead of raw `json.loads`, which rejected the file the moment it carried its first explanatory comment (added for the `contextual-orchestrator` provider block) with `Expecting property name enclosed in double quotes`. Comment markers inside string values, such as the `$schema` URL, are left untouched. - Download the pinned `uv` 0.12.1 exporter from the official GitHub Releases URL instead of `releases.astral.sh`, which now returns HTTP 403 and blocks org-wide OpenCode `coverage-evidence`. The SHA-256 pin is unchanged. The opener may follow one hop onto `release-assets.githubusercontent.com` or `objects.githubusercontent.com` and still rejects every other host, userinfo, non-HTTPS scheme, and nondefault port (ContextualWisdomLab/.github#1109). - Compared the trusted `uv` executable's post-install `--version` output against the real GitHub Releases build's full string, `uv 0.12.1 (x86_64-unknown-linux-gnu)`, instead of the bare `uv 0.12.1` the prior check required; the genuine release binary always prints the target triple, so every installation was failing the pin check immediately after the archive download itself was fixed (ContextualWisdomLab/.github#1109). diff --git a/docs/pr-review-and-merge-procedure.md b/docs/pr-review-and-merge-procedure.md index feba6a052..8da4703f3 100644 --- a/docs/pr-review-and-merge-procedure.md +++ b/docs/pr-review-and-merge-procedure.md @@ -102,16 +102,16 @@ cannot merge unreviewed. ## Head mutations need a workflow-starting credential GitHub never starts a new workflow run for an event created with the workflow -GITHUB_TOKEN (GitHub, 2025).
