code-infra-01 82ddca6521 fix(git-tools): pr-merge queue guard reads CI status from the BASE repo (fork PRs, B1)
ci/woodpecker/pr/ci Pipeline was successful
For a fork PR, pr-metadata's headRepository names the fork (e.g.
stack-mos-dt-0/stack), and pr-merge passed it to ci-queue-wait via -R.
Woodpecker posts commit statuses on the BASE repository, so the guard read
statuses:null from the fork and every fork merge aborted with
state=malformed rc=3 (#1215, gate-merge-01 B1; standalone queue-wait
against the base repo returns terminal-success on the same sha). Same
family as d339e8fd.

- pr-metadata.sh: normalize baseRepository from Gitea base.repo.full_name
- pr-merge.sh: pass the BASE repo to the queue guard; head repo remains
  for head-sha identity; origin-repo fallback when metadata carries no
  base repository (correct for same-repo PRs)
- test-pr-merge-fork-ci-status.sh: fork-PR regression, CI-reachable via
  test:framework-shell beside its siblings; asserts the guard NEVER sees
  the fork and gets the base repo, head branch and exact sha
- test-pr-merge-queue-branch.sh: its old -R assertion pinned the fork
  repo, i.e. the bug; now asserts the base repo

## Branch Model and Merge Process — `main` and `next` (CANONICAL)
**Every contribution targets `next` first. No exceptions.** Features, fixes, tests,
docs, and policy changes all take the same route; urgency changes queue priority,
never the route. Agents never commit to or merge into `main`.
| Branch | Role | Who merges into it |
| ------ | ---------------------------------------------------------------- | --------------------------------------------------------------------------- |
| `next` | Integration trunk — the only PR target for contributions | The designated merge-gate agent, after all gates pass. Never the PR author. |
| `main` | Stable/release line — receives promotion merges from `next` only | Jason only (or an agent he explicitly delegates for a named promotion). |
### Contribution sequencing (in order, no skipping)
1. **Issue first.** Work is tracked in a Gitea issue before a branch exists. The
issue number appears in the branch name and the PR body.
2. **Branch from the current `origin/next` head.** Name it
`feat/…`, `fix/…`, `docs/…`, or `test/…` with the issue number
(e.g. `docs/1214-branch-process`). Record the base SHA in the PR body.
3. **Develop with evidence.** Applicable tests accompany the change. Hooks are
never bypassed (`--no-verify` is prohibited). Stage explicit paths — never
`git add -A`.
4. **Open the PR against `next`.** The body states: scope, base SHA,
verification commands with results, and any known pre-existing failures on
the base — documented, not retried to green and not absorbed silently.
5. **CI must be terminal-green on the exact head.** All bounded Woodpecker
steps succeed (`verify-terminal-green` contract). Pipelines for fork PRs
start `blocked`; a maintainer approves the run — approving CI is not
approving the PR.
6. **Independent review. Self-merge is prohibited** — for every agent, on every
PR, including trivial ones. Where the change touches protected or
contract-bearing content, the reviewer verifies the exact head
(exact-byte/exact-blob comparison), not a description of it. An `AMEND`
verdict returns the PR to its author; the reviewer's gate stays held until
a fresh exact head passes.
7. **Merge into `next`** happens only after CI green + review pass, pinned to
the reviewed head SHA (a post-review push voids the review).
8. **Promotion `next` → `main`** is a deliberate, Jason-owned reconciliation
merge — not part of any contribution's lifecycle. Contributors are done at
step 7.
### Responsibilities
- **Contributor** — base pinning, green CI, evidence in the PR body,
responding to AMEND verdicts, never merging own work.
- **Reviewer / merge gate** — independent verification on the exact head;
holds and lifts gates; executes the merge into `next`.
- **Orchestrator / adjudicator** — cross-PR sequencing, disposition when PRs
collide, conflict adjudication.
- **Jason** — `next``main` promotions, merge-authority grants, collaborator
and token provisioning. Agents cannot grant themselves or each other any of
these.
### Hotfixes and divergence
- A hotfix follows the same path: branch from `next`, PR to `next`, gates,
merge, then an expedited Jason-owned promotion if `main` needs it urgently.
Committing the fix to `main` directly is prohibited even under pressure.
- **Never land work on `main` that is not on `next`.** This has happened
(issue #1152's goal controller reached `main` without reaching `next`) and
every later PR paid for it. If it happens anyway: transplant the work onto
a `next`-based branch with provenance-preserving commits
(`git cherry-pick -x` or explicit SHA references in the messages), PR it
through the normal gates, and let promotion re-align `main`. Do not
hand-patch `main` to compensate.
- Force-pushing a branch you do not own is prohibited; rebasing your own PR
branch is fine before review, and voids any review already given.
## Database and Local Runtime Safety
- Current local data-layer work uses in-process PGlite; leave `DATABASE_URL` unset.
