name: prepush
description: Pre-push gates for a repository set up for crafter-review (`crafter-review init`). Runs the pipeline's procedure end to end — Gate 0 build/tests + freeze (identity, trailers by the config's rule, clean tree, no merges, fast-forward), the application and the database under test brought up from the frozen tree, the driver run of the lenses the config turns on - every lens is off until it does (repo-better-solution → repo-functional with the Playwright MCP → repo-bug-prover and repo-security side by side → repo-facts, the commit truth) via crafter-review, the fix/rerun loop, the owner's approval of the hash, verify, push. Nothing is pushed unreviewed or unapproved.

Follow the pipeline's procedure, `prepush.md`, EXACTLY — read it now, in
full, before anything else: `flatpak run net.catcrafts.CrafterReview doc
--path prepush` prints where it is; read that file with the Read tool.
Every command below is spelled `flatpak run net.catcrafts.CrafterReview
<command>`: the Bash tool sees no alias. This skill only adds the mechanics
of running it:

1. **Identify** the repository root (the driver runs from there), the range
   (`git log --oneline @{u}..HEAD`, or `$(git merge-base HEAD <config base>)..HEAD`
   for a branch that tracks nothing yet), the slug (the branch or release
   name), and the config: `flatpak run net.catcrafts.CrafterReview config`
   must print no problem (every lens is off until a mode lists it:
   `modes.<mode>.lenses` names what this repository runs, `effort` how hard).
2. **Gate 0**: run the config's `gate0` commands on that HEAD and keep their
   output. Then freeze:

   ```
   flatpak run net.catcrafts.CrafterReview freeze --slug <slug> [--worktree]
   ```

   It refuses on any failed check — fix the commits, never the check. It
   prints the hash and the exact run command, also in
   `.review-gates/push/<slug>/run-line.txt`.
3. **The application and the database under test** (when a lens that runs
   has the browser — `browser`, `browser+supabase`; the functional lens by
   default — or the database — `supabase`, `browser+supabase`; nothing to
   start when none does): start them from the tree the lenses read (the
   checkout itself for `--trees .`, the worktree for `--worktree`) with the
   config's `functional.start` (or `supabase.start` when no lens drives the
   application), and confirm `functional.appUrl` answers. The login fixture
   named in `functional.login.fixtures` must exist (the stack's seeder
   writes it). A lens with the browser drives Playwright's Chromium: when the
   first browser pass cannot start it, run
   `flatpak run net.catcrafts.CrafterReview browser install` once. With
   `slots.*`, start slot 1 (`slots.start` with n = 1), then run
   `flatpak run net.catcrafts.CrafterReview slots --artifact
   .review-gates/push/<slug>/`: it says how many slots fit in free memory
   and prints the start commands for the missing ones — run those side by
   side and wait for every one to finish (`<slots.dir>/<n>/slot.json`
   appears when a slot is up). After `freeze --replace`, stop the slots
   (`slots.stop`) and bring them up again from the new HEAD. The driver refuses a gate while the database at
   `supabase.dbUrl` does not answer or its applied migrations are not
   HEAD's: reset the stack from the frozen tree, after every
   `freeze --replace` too. Do not edit that tree while the run is on.
4. **Gates 1–4**: run the printed command from the repository root in a
   detached background shell (`setsid nohup … > <log> 2>&1 < /dev/null &`);
   poll `~/.cache/review-gates/<hash8>-run-<n>/progress.json` and `log.txt`.
   Add `--context-paths` for the evidence dirs the messages' claims rest on.
   To stop a run: `flatpak run net.catcrafts.CrafterReview stop <its scratch
   dir>` (the last word of its gate-0 log), never a kill of a pid — inside
   the Flatpak the pid it shows is not the driver. Exit 0 = push-ready / 1 FIX
   FIRST / 2 INCOMPLETE, PARTIAL or CONFIRMING (gates clean, static code units
   still owe clean reads of 3 — run the SAME command again on the same hash,
   it is the next round, until SEND-READY) / 3 preflight; the dump path is
   the last stdout line.
5. **On FIX FIRST** — per undischarged finding exactly one disposition
   (prepush.md §Verdicts): FIX it (amend/rebase the commit in another
   worktree, `freeze --replace` into the same dir, restart the application
   and the stack from the new HEAD, rerun — clean units are reused automatically), REFUTE
   it with a fact (register a `refuted` entry), else an OWNER ASK — batched,
   one message per gate stop (finding, evidence, proposed grounds, cost of
   fixing instead), blocking until they rule; their ruling becomes a
   `waiver-owner` entry (dated, `supersedes`, `anchors` with counts,
   `grounds`, `carry`). A `contests` entry is a lens claim: re-check its cited
   evidence first; a surviving contest on an owner entry goes to the owner.
   Notes never block — bank each per its kind; an `unverified` note names a
   manual check the owner sees at Gate 5. INCOMPLETE is never a pass: rerun.
6. **Rounds** go in `.review-gates/push/<slug>/manifest.md`
   (`flatpak run net.catcrafts.CrafterReview doc manifest` prints the
   template; test runs with `--only`/`--units` never).
7. **Gate 5 — the owner**: present the frozen patches themselves, the rounds
   table, the discharged findings with grounds, every contest, all notes —
   then STOP. Nothing is pushed until they explicitly approve that exact hash.
8. **Push**: `flatpak run net.catcrafts.CrafterReview freeze --slug <slug>
   --verify` → MATCH; `git push` (and the pull request where the flow is a
   PR); `approved:` / `pushed:` in the manifest; stop the application and the
   stack (`functional.stop`, `supabase.stop`) when they were started; `git worktree remove .review-gates/trees/<repo>-<hash8>`
   when one was used.
