// tests/build/cursor-visibility.test.ts — Plan 04-06 cursor-visibility
// defensive regression pin (RESEARCH Finding 4 closure).
//
// Pins that src/offscreen/recorder.ts:285 carries the `cursor: 'always'`
// getDisplayMedia constraint — the original Phase-5 deferral was lifted
// opportunistically in Plan 01-09 (recorder.ts:285) and the back-patched
// Plan 04-06 closes the audit loop by both (a) re-verifying the literal
// via this defensive grep test and (b) flipping the stale "deferred to
// Phase 5" lines in .planning/phases/01-stabilize-video-pipeline/
// 01-07-SUMMARY.md (Task 3 of Plan 04-06).
//
// Polarity at land: GREEN-on-arrival — the literal already exists at
// recorder.ts:285 (verified at 04-06 re-plan iter-2; confirmed via
// `grep -n "cursor: 'always'" src/offscreen/recorder.ts`).
//
// SCOPE: node-env file-grep regression pin. Does NOT instantiate the
// MediaStream pipeline (out of scope for unit tests; the runtime visibility
// behavior is operator-empirical and out of the automated test loop —
// per UI-SPEC § the operator confirms the cursor appears in
// `video/last_30sec.webm` playback after a SAVE).
