## Context
The setup-project skill treats "build from a Dockerfile" as priority 6 — "last
resort, avoid if possible" — with no formalized path for apps whose upstream
lacks a working Dockerfile. When we end up writing one to get the deploy green,
that Dockerfile stays private in the infra repo and upstream never benefits.
## This change
Adds a closed-loop flow: when we author a new Dockerfile (or fix a broken
upstream one) and the deploy is healthy for 10 minutes, auto-open a PR against
the upstream repo so the self-hosting community gets the working recipe.
Flow:
1. Classify dockerfile_state during research phase (image-used / used-as-is /
fixed-broken-upstream / written-from-scratch). Persist to
modules/kubernetes/<service>/.contribution-state.json.
2. After Terraform apply, run scripts/stability-gate.sh — polls pod Ready +
HTTP 200 every 30s x 20 iterations, requires 18/20 successes.
3. On pass with a trigger state, scripts/contribute-dockerfile.sh does the
GitHub API dance: fork → merge-upstream → branch → commit Dockerfile /
.dockerignore / BUILD.md via Contents API → open PR with body rendered from
templates/PR_BODY.md. Idempotent (skips on recorded PR URL, existing fork,
existing branch, open PR, upstream landed a Dockerfile mid-deploy).
GitHub API via curl (gh CLI is sandbox-blocked per .claude/CLAUDE.md); token
pulled from Vault (`secret/viktor` → `github_pat`). Commits include
Signed-off-by for DCO-enforcing repos. Fork branch name is `add-dockerfile`
for written-from-scratch or `fix-dockerfile` for fixed-broken-upstream, with
timestamp suffix on collision.
## Files
- SKILL.md — state classification table, quality bar checklist, §8b stability
gate, §10 contribute-upstream step, checklist updates
- scripts/stability-gate.sh — 10-minute health probe
- scripts/contribute-dockerfile.sh — GitHub API orchestrator
- templates/PR_BODY.md — `{{VAR}}` placeholder template for PR description
- templates/Dockerfile.README.md — BUILD.md template shipped with the PR
## What is NOT in this change
- No Woodpecker / GHA changes (skill-local flow).
- No auto-tracking of merge/reject outcomes upstream (manual follow-up).
- Not yet exercised end-to-end; first real-world run will validate the API
dance. Plan to dry-run against a throwaway sink repo before pointing at a
real upstream.
## Test Plan
### Automated
- bash -n on both scripts → pass
- Manual read-through of SKILL.md — step numbering coherent, existing
§1-9 untouched semantics, new §8b/§10 reference real files
### Manual Verification
1. Next time setup-project onboards a Dockerfile-less app:
- Confirm .contribution-state.json is written with `written-from-scratch`
- Run stability-gate.sh — expect 18/20 passes on a healthy deploy
- Run contribute-dockerfile.sh — expect a fork + branch + PR on ViktorBarzin
- Verify contribution_pr_url is back-written to the state file
2. Re-run contribute-dockerfile.sh → must be a no-op (idempotent)
3. Upstream-archived case: manually archive a test upstream → re-run →
expect SKIP, no PR created
[ci skip]
