Delete Branch "fix/14-cascade-gitea-dispatch"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Closes molecule-core#14. Option A per devops-engineer + security-auditor consensus (Option B was unsafe — cron-poll does not cover the runtime → template fan-out axis).

Cannot merge as-is — Gitea dispatch API empirically does not exist
Follow-up to the secret-name fix in
569df259(TEMPLATE_DISPATCH_TOKEN → DISPATCH_TOKEN to match the plumbed secret on this repo).Verified empirically against this Gitea (1.22.6) — there is no repository_dispatch / workflow_dispatch trigger API:
Swagger (/swagger.v1.json) confirms: the only actions/* endpoints in 1.22.6 are actions/secrets, actions/variables, actions/runners/registration-token. No trigger surface at all.
The earlier API-shape note in this PR (claiming POST /api/v1/repos/{o}/{r}/dispatches would work) was wrong. Apologies — should have probed before designing.
Path forward
Proposing a v2 pivot: push-mode cascade. Each template already has on: push: branches: [main]. Replace the curl-dispatch loop with: clone each template, update a .runtime-version file with the published version, commit + push. The on-push fires the template's existing publish-image.yml. DISPATCH_TOKEN's existing write:repository scope is sufficient.
Awaiting orchestrator alignment before pushing v2.
Phase 2 design — push-mode cascade for publish-runtime → templates
Empirically blocked v1: Gitea 1.22.6 has no repository_dispatch / workflow_dispatch trigger API. v2 substitutes git push as the cross-repo cascade signal. Each template already has
on: push: branches: [main]andworkflow_dispatchon itspublish-image.yml— both of which fire the existing reusable build workflow. We hijackon: push.1.
.runtime-versionfile shapeJust the version string, one line, no trailing junk:
Path: repo root
.runtime-version. No JSON, no signer, no timestamp.Rationale:
git log -- .runtime-versionis canonical. Don't duplicate state.catit during incident triage. JSON is a small but real friction tax.The template's
publish-image.ymlis updated separately (one-time PR per template, mechanical) to read the file and forward to the reusable workflow:Falls back to
client_payload(legacy GitHub flow if it ever returns) →inputs(manual workflow_dispatch) →.runtime-version(push cascade) → empty (Dockerfile default).2. Conflict handling
Strategy: pull-rebase loop, bounded retries, surface failure if exhausted.
Why pull-rebase over
--force-with-lease:--force-with-leaseoverwrites the racing publisher's commit silently. If v0.1.7 and v0.1.8 publishes race, force-with-lease means whoever pushes second wipes the other's commit and the file ends up with whichever version pushed last — but the lost commit is not visible in the log. Audit hostile.Bounded at 3 retries. After that, the template is in
FAILEDand the operator retries manually.3. Failure handling — partial cascade
Partial-state is acceptable. Already used the same pattern in v1 (and the v1 design doc justified it). Three reasons:
publish-runtimewith sameversioninput → idempotent (see §4) → retries only the failed templates implicitly.Implementation:
set +earound the cascade loop, collectFAILED.4. Idempotency — re-runs are no-ops
Before the commit step, diff
.runtime-versionagainst the new value:When publish-runtime is re-fired with the same
version(e.g. operator retrying after a partial failure), templates already at that version contribute zero commits. No spurious push, no spurious template rebuild.Edge case: operator passes a lower version (downgrade). The diff is non-empty, so we'd commit + push the downgrade. Acceptable — that's the operator's stated intent. We don't second-guess.
5. Hostile self-review — 3 weakest spots
W1 — wall time scales linearly with template count. Today's 9 templates × (clone 5s + commit 1s + push 2s) ≈ 80s sequential, vs. v1's curl-burst at ~5s. Acceptable now; if the template list grows past ~20 the operator will notice. Mitigation if/when needed: parallelize via
&+wait. Not in v1 to keep failure-attribution simple (parallel = interleaved logs).W2 — depends on a per-template publish-image.yml edit that doesn't exist yet. Today every template's publish-image.yml only forwards
runtime_versionfromclient_payloadorinputs— neither populated on push. Until the 9 small PRs land that teach publish-image.yml to read.runtime-version, the cascade fireson: pushbut rebuilds with whatever requirements.txt already says. Sequencing requirement: land the 9 template-side PRs BEFORE merging molecule-core PR #20. Otherwise the first publish-runtime push triggers 9 builds that pin the old version — silently green CI, broken behavior. This is the highest-risk failure mode.W3 — bot identity smell. publish-runtime pushes 9 commits per release, all authored by the
devops-engineerpersona. Per saved memoryfeedback_github_botring_fingerprint, this is exactly the access-pattern that got Molecule-AI banned 2026-05-06. Mitigations:chore: pin runtime to X (publish-runtime cascade)so it's clearly workflow-driven.Co-Authored-By: molecule-core/publish-runtime <noreply@moleculesai.app>trailer.Sequencing plan
molecule-ai-workspace-template-<runtime>repo — teachpublish-image.ymlto read.runtime-version. All can land in any order, no inter-dependency. Estimated: ~30min sequentially.workflow_dispatchof publish-runtime with an alpha version (e.g. 0.0.0-test-cascade), watch all 9 templates' on-push runs fire. If green, kick the real publish.Open questions for orchestrator:
.runtime-version-reading PRs to all 9 template repos directly (DISPATCH_TOKEN can do it), or should those go through normal review?569df259) stays — independent fix worth keeping. OK to include in the v2 force-push?v2 pushed — hostile self-review (3 weakest spots)
Head is now
607444e71b. PR remains open + mergeable. The 8 template-side PRs have all merged; .runtime-version + resolve-version pattern is live across all cascade-active templates.W1 — cwd handling on early-exit
Each template iteration does
cd "$CLONE"for the file work, thencd - >/dev/nullto return. If the iteration short-circuits viacontinue(clone-failure path, runscdonly after the clone), the next iteration'srm -rf "$CLONE"runs from whatever cwd the prior template left us in. Withset +ethis is non-fatal but messy. Mitigation if it bites: switch to subshell(cd ... && ...)for clean scoping. Not done in v2 because the failure modes are bounded (no destructive ops outside$WORKDIR).W2 — assumes
mainis the default branch on every templategit push origin HEAD:mainand the rebase target are hardcoded. If a template ever moves tomaster/trunk, push silently fails with "remote ref does not exist" and the template lands inFAILEDuntil someone notices. Today (verified 2026-05-07): all 8 templates usemain. Long-term: readgit remote show origin | grep 'HEAD branch'per-template, but that adds an extra round-trip × 8 — overkill until we have a non-main template.W3 — sequential per-template loop
8 templates × ~10s clone+commit+push happy-path = ~80s wall time. Worst case: 8 × 3 retries × ~12s = 288s. Acceptable for a publish workflow that runs 1-2× per day on a non-blocking job. If template count grows to ~20+, this becomes the long pole. Easy parallelization later via background
&+wait, but that interleaves logs and complicates failure attribution. Defer.Open mitigation tradeoffs (none blocking)

Push-mode cascade replacing curl-dispatch (Gitea has no repository_dispatch). Drops codex from auto-publish via per-template probe.
