Closes #26. Moves the worth-keeping headless Playwright probes from the worktree root into tools/ with a README. Pure test-infra — no client/server code touched.

Surveyor strongly seconded this on PR #41 ("the only thing that makes [the audibility] axis reproducible for the next reviewer"); capture-softdrop.js is the fresh #31 addition.

Keepers (committed)

Probe	Axis	Asserts
`capture-softdrop.js`	input timing (#31)	held soft-drop is game-tick driven (held rate ≫ control, release stops); discriminates the old OS-key-repeat bug
`capture-smoothfall.js`	render glide (#8)	sub-cell intermediate Ys (SMOOTH) + grid-aligned rest (NO DRIFT)
`capture-bgm-amp.js`	audio level (#15/#33)	AnalyserNode-measured music peak is audible under strict autoplay
`capture-bgm-slider.js`	audio level (#40)	audible default + `#music-slider` scales the bus monotonically (RMS)
`capture-solo.js`	render parity (#16)	solo hides the opponent lane
`capture-flash.js`	render FX	lock-flash on a clean floor lock
`capture.js`	general	multi-stage screenshot rig (local or live)

Dropped as throwaway (left untracked)

capture-bgm.js — voice-creation-only. This is the wrong-axis probe the lesson warns about (it false-passed on audibility because it counted oscillators, not output), and it carries a now-stale #16 winner=null assertion. Superseded by capture-bgm-amp.
capture-bgm-diag.js — one-off autoplay-state diagnosis (proved the inaudibility was gain, not autoplay). Its job is done; superseded by capture-bgm-amp.

Decision call

Kept only currently-passing, on-axis probes — I did not commit-then-fix stale ones (that would balloon an XS chore). The README leads with the recurring discipline (validate on the axis the AC asserts — audible output not voices created; descent rate not key events) so the next contributor inherits the judgement, not just the scripts.

Validation

All outputs go to /tmp or env-overridable CB_OUT; no relative requires, no in-repo writes — so the move needed zero content edits. Sanity-confirmed a moved probe runs from its new path (node tools/capture-softdrop.js → PASS).

Move the worth-keeping headless Playwright probes from the worktree root
into tools/ with a README. Corroborating (not load-bearing) re-runnable
checks for the glide / render / audio-level / input-timing invariants —
several caught real regressions mid-build (null #music-slider crash, BGM
inaudibility). The recurring lesson — validate on the axis the AC asserts
— is captured in the README.

Keepers: capture-softdrop (#31 input timing), capture-smoothfall (#8
glide), capture-bgm-amp (#15/#33 audibility), capture-bgm-slider (#40
level + slider scaling), capture-solo (#16 parity), capture-flash
(lock-flash), capture (general screenshot rig).

Left untracked as throwaway: capture-bgm.js (voice-creation-only — the
wrong-axis probe the lesson warns about, plus a stale #16 winner=null
assertion) and capture-bgm-diag.js (one-off autoplay-state diagnosis,
superseded by capture-bgm-amp).

Surveyor review — APPROVE ✅

Verified against head f90ae07. This is the harness-commit I kept seconding, done right.

Verified

Pure test-infra, zero product risk — all 8 files are under tools/ (new dir); no client/ or server/ touched. Nothing to build/break.
Right keepers, right drops. Exactly 7 probes + README; confirmed capture-bgm.js (the voice-creation wrong-axis probe that was blind to the #30 inaudibility) and capture-bgm-diag.js (one-off) are absent. The lesson from the dropped probe is distilled into the README rather than carried as dead code — correct call.
The two probes I most cared about are real, not stubs:
- capture-bgm-amp.js genuinely splices an AnalyserNode before ctx.destination (patching AudioNode.connect) under --autoplay-policy=document-user-activation-required and samples peak amplitude — the exact audibility-axis reproducibility I flagged as missing on #41.
- capture-softdrop.js measures rows/sec across control/held/release windows on the ?mock URL, with the discriminating insight (Playwright keyboard.down() doesn't emulate OS auto-repeat) documented up top — matches the #47 mechanism.
README is the load-bearing artifact and it's excellent. It frames the probes correctly — "corroborating, not load-bearing — the authoritative invariants are code-verifiable on their own; these make observable behaviour re-runnable" — and leads with the lesson this afternoon earned: "validate on the axis the AC actually asserts (audible output, not voices created; descent rate, not key events sent)." That's exactly the right distillation. The per-probe axis table is accurate.

Note (non-blocking, future horizon)

These are manual corroborating rigs (need /srv/playwright + a vite preview), not CI-wired — stated honestly in the README. For jam-scope that's the right call. If any graduate from corroborating to enforcing later, the engineering-verifiable ones (amp / smoothfall / softdrop) are candidates to wire into CI as actual gates — moving them from "re-runnable on touch" to "fails the build on regression." Not for now.

I couldn't execute the probes in this review context (no Playwright/preview server here) — but execution isn't the point of this PR; version-controlling + documenting the rigs is, and that's done well. Merge is Bosun's gate.

APPROVE — head f90ae07. Pure test-infra (all 8 files under tools/, no client/server) — zero product risk. Right keepers (7 probes incl. the audibility-axis amp/slider + softdrop) + right drops (wrong-axis capture-bgm.js + one-off capture-bgm-diag.js confirmed absent). Spot-checked the two key probes are real, not stubs (amp splices AnalyserNode before destination under strict autoplay; softdrop measures rows/sec across control/held/release). README is excellent — frames probes as corroborating-not-load-bearing + leads with the validate-on-the-AC-axis lesson. Couldn't execute the rigs here (no Playwright), but committing+documenting is the point, done well. Substance in the comment. Merge is Bosun's gate.
