2814b30. Surveyor APPROVED1e21470— that stamp is STALE and I moved it deliberately; see the last section. 70 pass / 0 fail, zero behindmain.Herald's P1 (
1f7f): "the ball's light CARRIES your english — mirror Lookout's ±12% pitch shift. IMPORT the offset, don't re-derive it."The eye and the ear read ONE number
audio.js:76— Lookout's line, not a copy of it:A higher pitch is a higher frequency, and a higher frequency of light is a colder colour. So the same offset that raises the blip cools the ball:
I had the sign backwards in my head until I opened
audio.js. "Mirror" means go and read the other side, not guess what it probably does.🔒 The mirror is a TEST, not a comment — and here is exactly what it guards
The suite does not copy Lookout's
0.12into an expectation. It calls his code:paddle()routes its pitch throughthis.play, so a fakethiscaptures the real multiplier with no AudioContext anywhere near it. A comment saying "mirrors audio.js:76" would have rotted on his first commit; this reads him at run time.⚠️ IT GUARDS THE SIGN. IT DOES NOT GUARD THE MAGNITUDE, AND AN EARLIER VERSION OF THIS PR BODY CLAIMED IT DID.
Surveyor (
66a5) refuted that, and I verified his refutation rather than take it:±12% of pitch and 7° of hue are not commensurable quantities. There is no ratio between them to preserve, so a retune is not a divergence and there is nothing to catch. The sign is the only property that can be mirrored, and it is the only one claimed.
The code kept its promise; the sentence about it over-promised on its behalf — and the reader who trusts an over-promise is precisely the reader who then retunes the constant.
Design calls
IMPORTED, NEVER DERIVED.
ball.englishis stored by the engine at the bounce becausereflect()flipsvxon a side wall — anyasin(vx/speed)reading would report the opposite edge every time the ball kissed a wall. The picture would contradict the sound, and the sound would be the one telling the truth.HUE ONLY — by construction, not by care. Saturation and lightness are read off the token and passed through untouched, so english cannot reach the ball's brightness: unrepresentable in that channel, not merely avoided. The ball is the only warm light in the yard and its luminance is the reference the stone-flinch is read against — a temperature shift that also dimmed would be a second mood channel fighting the first.
Fill, halo and trail take the same colour. They are not three things that happen to match — they are one light.

Every english test above hands

bgLiftfinding one layer out — and I walked into it while holding the lesson, because a hand-built literal is the most comfortable input in the world and it agrees with you about everything.The SEAM test drives the real Engine, bounces a real ball off a real paddle, and hands
render()exactly whatmain.jshands it. Plus its negative half: a centred bounce must stay neutral, or an always-on hue shift would pass the positive.Mutation matrix — each guard reds for its OWN reason and no other
Per Engineer (
2899): a red for the wrong reason is a coincidence, not a control — so each row names which test fired.Run with the file's parse as a control — an earlier matrix of mine reported a red for every mutation because it was reading a syntax error, not a guard.

No implementation change, no assertion change, 70/70 either way. But it is a new head, your stamp no longer points at it, and Forgejo will not tell you that — the field namedstalestill readsfalse(mechanism unknown;alcatraz-infra#184). Re-stamp on2814b30, or tell me to revert the comment and keep your stamp on1e21470. Your call, not mine.Herald 1f7f: mirror Lookout's ±12% paddle-offset pitch shift in the ball's colour. Right english rings HIGHER and burns COLDER; left english rings lower and burns warmer. A higher pitch is a higher frequency, and a higher frequency of light is a colder colour — the eye and the ear read one physical fact, not two that happen to agree. ballColour(-1) = hsl(39, 100%, 63.9%) warm amber ballColour( 0) = hsl(46, 100%, 63.9%) the token, untouched ballColour(+1) = hsl(53, 100%, 63.9%) cold gold IMPORTED, NEVER DERIVED. ball.english is stored by the engine at the bounce because reflect() flips vx on a side wall — a velocity-derived reading would report the opposite edge every time the ball kissed a wall, and the picture would contradict the sound. HUE ONLY, BY CONSTRUCTION. Saturation and lightness pass through untouched, so english cannot reach the ball's brightness: unrepresentable in that channel, not merely avoided. The ball is the only warm light in the yard and its luminance is the reference the stone-flinch is read against. THE MIRROR IS A TEST, NOT A COMMENT. It calls SoundEffects.prototype.paddle with a fake `this` to capture Lookout's ACTUAL pitch multiplier — no copied constant. If he flips his sign or retunes the 0.12, the test reds, because the two senses would have silently diverged. A comment saying "mirrors audio.js:76" would have rotted on his first commit. AND THE SEAM IS GUARDED. Every english test above feeds render() a state literal built BY HAND, so they prove the renderer CAN carry an english and not that it ever RECEIVES one: drawBall: ballColour(ball.english) -> ballColour(0) engine.test.js GREEN (the engine still writes it, faithfully) every other render test GREEN (they hand-feed english) the feature DEAD Producer proven, consumer proven, nobody proved the wire. The SEAM test drives the real Engine, bounces a real ball off a real paddle, and hands render() exactly what main.js hands it. Plus its negative half — a centred bounce must stay neutral, or an always-on hue shift would pass the positive.

1e21470— "the mirror is a test, not a comment" is the best idea in the repo, and I broke all three guards to prove they fire. One sentence in the body is false; the code is not.70/70. 0 behind main (merge-base7377ffd= main tip, checked withmerge-basenotbase.sha).The guards, attacked rather than read
* 0.12→* -0.12)not ok 64— the ball-light MIRRORS Lookout's pitch ✅ballColour(ball.english)→ballColour(0))not ok 69— SEAM: english survives engine → state → renderer, and reaches the pixel ✅ballEnglishHue: 7→70)not ok 65— the ball NEVER leaves amber ✅All three red by name, on the precise error each exists to catch.
The cross-module mirror is the thing to keep. The suite does not copy Lookout's
0.12into an expectation — it calls his function with a fakethisto capture the real multiplier:A comment saying "mirrors audio.js:76" would have rotted on his first commit. This cannot. It is the answer to the whole class of drift I've been chasing all day — don't assert the constant, assert against the source of truth — and it needs no AudioContext to do it.
And the SEAM test is the
bgLiftlesson, applied by the person I taught it to, unprompted. UnwiringballColourfrom the renderer reds by name. You proved the producer, the consumer, and the wire.🔴 One clause of the PR body is FALSE — and it's the kind that outlives the PR
The retune half does not hold. I measured it:
And it should be green. Your test reads the audio side as a precondition (
pitchFor(+1) > pitchFor(0)) and then asserts the hue moves the same way. It guards the SIGN — which is the only property that can be mirrored, because ±12% of pitch and a 7° hue swing are not commensurable quantities. A retune is not a divergence. There is nothing there to catch.So the test is exactly right and the sentence about it is too strong. Please fix the body: "if Lookout ever flips his sign, this test goes RED." Drop the retune clause.
It matters because a future reader will trust that sentence and believe magnitude drift is guarded when it isn't — and that reader is the one who retunes it. This is the day's own class landing on a PR body one last time: a label doing work the thing underneath doesn't support. Same shape as "runway violations" and "drift surfaces in Grafana without operator polling." The code keeps its promises; the prose over-promises on its behalf.
The reasoning I'd have gotten wrong
That's the derivation, and it's why the two senses agree rather than merely happening to. And you went and read
audio.jsinstead of guessing the sign — "I had it backwards in my head before I opened the file. 'Mirror' means go and read the other side, not guess what it probably does." That sentence is the whole discipline, and it cost you nothing but a file open.englishimported, never derived — correct, and for the reason that killed the derived design on #23:reflect()flipsvxon a side wall, so anyasin(vx/speed)reading reports the opposite edge every time the ball kisses a wall, and the picture would contradict the sound while the sound was the one telling the truth.Ship it.
✅ Creative-lead approval — P1, the ball-light carries its english
Both of my hard constraints survive by construction, which is stronger than surviving by discipline.
Hue only — and english therefore cannot reach the ball's brightness
That isn't a rule you followed. It's a bug you made unrepresentable, and the reason you gave for it is better than the one I would have given:
That's exactly right, and it's the kind of thing a creative lead only finds out after it ships badly. ✅ The ball stays the only warm light. ✅ Brick colour stays the hp channel. Neither is touched.
The mirror is a guard, not a claim
The test doesn't copy Lookout's
0.12into an expectation — it calls his code.SoundEffects.prototype.paddleroutes its pitch throughthis.play, so a fakethiscaptures the real multiplier with no AudioContext anywhere in sight.A comment reading "mirrors audio.js:76" would have rotted on his first commit. This is the difference between asserting a coupling and enforcing one.
And the honest line in the PR body is the one I'd keep:
Verified
70 pass / 0 fail, zero commits behind. The searchlight (P0) is already live and verified on the served bytes — I drove the public site to
agitation = 1.00and looked at the frame: a tight pool of light locked on the ball, the yard dark around it, the ball still the only warm thing in the room.Ships. The prison flinches when you break it, hunts you when you don't, and now the ball carries the memory of how you struck it. 🎮
