feat(harness): agent-drivable dev harness and CI that gates
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.

Promote a hand-driven playwright-cli session into a committed spec in e2e/ [name of the flow]

Promote the flow I just drove by hand into a committed Playwright spec. Flow: ${@:-infer it from the playwright-cli commands in this session}

This is a transcription with fixed substitutions, not a fresh test. Work from what actually happened in this session, not from what the UI looks like it should do.

1. Recover the flow. List the playwright-cli calls made this session, in order, and the assertion each one was really checking. Then, before writing anything, ask the running app what fired:

playwright-cli -s=yj eval "() => window.__yjEvents.names()"

Await the events that are actually in that list. Do not guess event names from backend/events/.

2. Substitute, one for one.

  • click e15 → a role or data-testid selector. Snapshot refs are per-snapshot and meaningless in a spec. If the only stable selector would be structural, add a data-testid to the Lit component and re-run make ui-test.
  • any sleep, or "it looked settled" → waitForEvent(app, 'X').
  • window.go.…callBinding(app, path, args), which times out.
  • a short fixture track → LONG_TRACK, if the flow needs playback to still be running on the next line. Every other fixture is 26 s.
  • getByRole('button', { name }) → add exact: true.

3. Place it. e2e/specs/<area>.spec.ts, importing test, expect and the helpers from ../support/fixtures.js — never @playwright/test directly. Match the surrounding specs' comment style: say what the test is protecting against, not what the lines do.

4. Prove it is a spec and not a recording. Three runs, in order:

make e2e E2E_ARGS='--grep "<name>"'    # it passes
make e2e E2E_ARGS='--grep "<name>"'    # again — catches dependence on
                                       #   state the first run left

then once more after restoring the database through /__test/, which catches dependence on state my hand-driving left behind — the single most likely way a promoted spec passes here and fails in CI. Leave the database as you found it: snapshot/restore, or reset in beforeEach.

5. Then the whole suite: make e2e. If the promotion turned up a new trap, append it to .planning/NOTES.md; if it turned up a bug, tell me rather than asserting the broken behaviour.
