The optimizer fix in the previous commit changes the observable
gameplay of `examples/platformer.ne` — pre-fix the player got
spurious enemy-1 stomp bounces every time coin 2 drifted into its
pickup window, so the README demo gif showed the player bouncing
mid-air around emu frames 85-125 instead of walking through the
coin at ground level. Regenerate `docs/platformer.gif` from the
fixed compiler so the README matches reality.
To stop this from drifting again, treat the gif the same way the
repo already treats `examples/*.nes`:
- `gifenc` + `jsnes` + the harness are deterministic, so a fresh
recording byte-matches a valid commit. Verified across two
back-to-back runs (identical md5).
- `.github/workflows/ci.yml`'s `emulator` job now renders the gif
into `/tmp/platformer.gif` and `cmp`s it against `docs/platformer.gif`,
emitting a `::error` annotation pointing at the exact rerun
command if the committed copy is stale. This piggybacks on the
existing puppeteer + node setup, adding ~20s to the job.
- `scripts/pre-commit` runs the same check locally, but only when
`examples/platformer.{ne,nes}`, `tests/emulator/record_gif.mjs`,
or `tests/emulator/harness.html` is staged, and only if
`tests/emulator/node_modules` is already installed. Cold-start
puppeteer is ~20s — too slow to pay on every commit, but cheap
enough to pay when something gif-relevant changed.
- The header of `tests/emulator/record_gif.mjs` and the project
conventions section of `CLAUDE.md` both spell out the rerun
command and the invariant, so the next agent doesn't have to
re-derive any of this.
