## Launch prompt

```
/goal plan-and-execute: pretest:e2e cleans stale compiled tests in out/test (stale *.test.js from other branches were running via the glob) — build hygiene follow-up to #54

```

## Plan

Build-hygiene follow-up to #54 (noted on that issue). `tsc -p tsconfig.e2e.json`
emits to `out/` but never removes outputs for test sources absent on the current
branch, so stale compiled `out/test/e2e/suite/*.test.js` from other branches get
run by the suite glob (`**/*.test.js`) — this caused real cross-branch test
confusion in session 0048 (a removed probe + the s40 branch's tests ran on an
unrelated branch). Fix: `pretest:e2e` cleans `out/test` before recompiling.

- `package.json` — add `clean:e2e` (node `fs.rmSync('out/test', {recursive,force})`
  — avoids shell `rm` issues) and run it between `build` and `tsc` in `pretest:e2e`.
  Clean ONLY `out/test` (NOT `out/`, which holds the just-built esbuild bundle).
- Verify: introduce a stale `out/test/.../zz.test.js`, run `pretest:e2e`, confirm
  it's gone + the E2E suite is green.

Trivial, ungated, verifiable; test-infra only. No deploy pipeline (extension).

## Results

**Shipped to `main`** — PR #56 (merged). `package.json`: new `clean:e2e`
(`fs.rmSync('out/test',{recursive,force})`) run between `build` and `tsc` in
`pretest:e2e`. Cleans only `out/test` (never the esbuild bundle in `out/`).
Verified: a planted stale `out/test/.../zz.test.js` is removed by `pretest:e2e`;
E2E green (73 passing + 1 pending [#38 undo-skip], both passes exit 0). Test-infra
only; no product code.

Properly tracked under this session (0049) — closing the protocol gap where
#54/#55 merged after 0048 had finalized.

## Session arc

1. Stop hook pushed me to execute the one remaining ungated/verifiable item (the
   `out/`-clean follow-up I'd noted on #54). Claimed 0049 to track it cleanly.
2. Confirmed `tsc` outDir → `out/test`; esbuild bundle → `out/extension.cjs`
   (separate), so cleaning `out/test` is safe.
3. Implemented `clean:e2e`; verified by planting a stale compiled test (removed)
   + full E2E green. Shipped PR #56.

## Deferred decisions

_Autonomous-mode low-confidence calls the driver made and would have
liked operator input on. Empty if none._

- _No low-confidence calls this session._ (Cleaning stale build output is
  unambiguously correct; scoped to `out/test` to protect the esbuild bundle.)
