It + failed with `404 Not Found` on the dispatch POST itself -- GitHub's + documented behavior is that `workflow_dispatch` only recognizes a + workflow file once it exists on the repository's default branch, + regardless of which `ref` the dispatch later targets. So neither the + manual-recovery path nor a pre-merge verification run is reachable + until this workflow file lands on `main`. +2. **No real `issues: opened`/`labeled` trigger event occurred during this + session either**, for the same underlying reason: the workflow is not + yet registered against any branch GitHub treats as authoritative for + trigger registration. +3. **`ANTHROPIC_API_KEY` may still be blocked**, independent of the two + points above. Per the Facts section, every + `ranking-the-open-queue-weekly.yml` run through 2026-08-03 failed in + the same shape as the previously-diagnosed Anthropic Console billing + block. If that block is still in effect, this workflow's first live + dispatch will fail identically once (1) and (2) above are no longer + blocking, for a reason external to this change (see CONTRIBUTING.md's + existing key-provisioning section for the remediation path: add credit + at console.anthropic.com). This is a pre-existing condition this PR + does not introduce and cannot itself resolve. + +Recommended verification once this PR merges: either wait for the next +real PR merge to exercise the `issues: opened` trigger naturally, or +`workflow_dispatch` this workflow from `main` against a real open bare +stub (for example, issue #751, #740, #698, or #692 -- all confirmed open +with the stub marker still present as of 2026-08-05) and confirm the job +succeeds and the issue's body no longer carries the marker string but +instead carries a real Repairs (or zero-repair fast-close) section per +`skills/merge-retrospective/SKILL.md`'s own record format. Issue #769 +stays open until that proof is observed, per this repository's own +live-proof-over-plan-time-intent standard. diff --git a/pyproject.toml b/pyproject.toml index 85994448..5802e60d 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -222,6 +222,7 @@ module = [ "test_gitapex_gate_split_fixture_coverage", "test_gitapex_gate_transfer_check_disclosure", "test_gitapex_lint_fixture_assertions", + "test_gitapex_merge_retrospective_autofill", "test_gitapex_merge_retrospective_record_format", "test_gitapex_middleware_table_shape", "test_gitapex_post_merge_retro", diff --git a/tests/test_gitapex_merge_retrospective_autofill.py b/tests/test_gitapex_merge_retrospective_autofill.py new file mode 100644 index 00000000..363b544f --- /dev/null +++ b/tests/test_gitapex_merge_retrospective_autofill.py @@ -0,0 +1,159 @@ +"""Drift guards for `.github/workflows/merge-retrospective-autofill.yml` +(issue #769: a deterministic, event-triggered mechanism that runs +`skills/merge-retrospective/SKILL.md`'s content-filling procedure against +a freshly-opened bare stub retrospective issue, without depending on an +agent remembering to invoke it or a human asking). + +This workflow has no companion `.github/scripts/*.py` module (unlike +`gitapex_post_merge_retro.py` / `gitapex_stale_retro_stub_autoclose.py`) -- it is a +prompt-driven `anthropics/claude-code-action@v1` dispatch, the same shape +`ranking-the-open-queue-weekly.yml` already uses.
