CLAUDE.md has claimed since the file was written that commitlint gates
the commit format in CI and that semantic-release runs off it. There was
no commitlint config, no workflow running one, and nothing invoking
.releaserc.yml — so the first thing every contributor and every agent
reads about this repo was false in two places.
scripts/commit-check.sh is the smaller honest answer: the grammar is one
regex, and commitlint would mean a Node dependency tree at the root of a
Go repo to run it. It is a commit-msg hook locally and a CI step over
every commit in a push, and its type list is .releaserc.yml's so the
check and the release rules cannot drift.
The semantic-release half is recorded as configured-but-not-wired rather
than implied to run.
Plan 007 phase 4 is verified by measurement, not by assertion, and
there was no way to produce a number: the fixture library is a few
dozen tracks and cannot show any of the findings.
- `cmd/gentestdata -bulk N` (`make bulkdata`) writes a ~50 000-track
library in 11 s / 466 MB by encoding six clips once and copying
them, while still tagging every file through `backend/tagwriter` —
a library the app cannot read back measures nothing.
- `make sandbox-seed-bulk` seeds from it through the same script and
the same discipline as any other seed: by running the app and
waiting for the real scan.
- `e2e/perf/measure.mjs` (`make perf LABEL=x`, `make perf-compare`)
takes fourteen measurements against a running app and writes them
to a gitignored `.dev/perf/<label>.json`. It wraps every bound Go
method, so "did that refetch the library" is a fact rather than an
inference, and records `longtask` entries, which is where a 25 MB
JSON parse on the main thread shows up and nowhere else.
It is not a spec and does not run in CI.
A coding agent could develop this repo's Go packages and could not
develop the application: every path to running YellowJacket ended in a
blocking GTK window, so 265 bound methods, 46 events, 33 component
directories and 13 stores had exactly one form of verification
available — `tsc --noEmit`.
The unlock is that `wails dev`'s dev server on :34115 serves the real
frontend with the real generated bindings against the same Go backend a
desktop window attaches to, so a plain Chromium under Xvfb gets a fully
functional app. Four test tiers now exist, cheapest first:
- `make ui-test` — 313 Vitest tests in a real browser in ~2 s, no app,
no backend, no display. Works because `frontend/wailsjs/` is a pure
passthrough to `window.go`/`window.runtime`, so faking just those two
globals runs the real bindings and the real store code.
- `make test` — services in-process, asserting on the payload the
frontend would receive, via a new `events.Emit` wrapper.
- `make dev-headless` + `playwright-cli` — the real app, driven
interactively, with an event bridge on `window.__yjEvents` and a
dev-only control surface at `/__test/`.
- `make e2e` — 19 of those flows frozen as Playwright specs.
`events.Emit(ctx, …)` replaces all 35 direct `runtime.EventsEmit` call
sites: wails' `getEvents` `log.Fatalf`s on any context without its
runtime, so those paths could not run under test and a background
worker could take the app down. Four packages had each hand-rolled the
same guard; nine more guarded on `ctx != nil`, which does not help.
`TestNoDirectRuntimeEmits` fails the build on a new one.
Fixtures are generated, not committed (`make testdata`), and seeds are
built by *running the app* — never by hand-writing config and DB rows,
which would be a second description of a valid YJ_HOME.
`.gitea/workflows/ci.yml` is the first workflow here that tests
anything; the other three only package, so `gitea_ci` reported only
packaging jobs and misled anyone asking whether a push was healthy.
Both jobs were prototyped to green in a bare ubuntu:24.04 container
before the YAML was written, which immediately caught `make lint`
linting three configurations that nothing builds: all three passes
omitted `webkit2_41`, so wails resolved webkit2gtk-4.0 — which Arch
still ships and Ubuntu 24.04 dropped.
Operational instructions live in `.pi/skills/yellowjacket-dev/`,
measured discoveries in `.planning/NOTES.md`, and architecture in
`CLAUDE.md` — split by tense, not by topic, because a topical split
gives every new fact two plausible homes. `make skill-check` fails a
commit if the skill cites a make target that does not exist.
Wire up Go's standard profiling toolkit so it's automatically available
in dev builds and completely absent from production. The profiling
package uses build tags (dev/!dev) to eliminate all pprof, trace, and
timing code from release binaries with zero new dependencies.
- backend/profiling: pprof HTTP server on :6060, /debug/trace endpoint,
block/mutex profiling, and TimeOp helper for structured operation timing
- scripts/profile.sh: interactive menu-driven script that auto-selects
free ports (8080-8089) so multiple profiles can be open simultaneously
- Instrumented key operations: app init, database init, player load/restore,
queue set/restore
- Makefile targets: profile, profile-cpu, profile-heap, profile-trace
- .gitignore: exclude trace-*.out and *.pprof artifacts
