jing efea7d98f3 [lane D] Round 1: first texture pack + audio proof, exact-tiling pipeline ...

Textures (6 walls + normals + wet matcap, $0, ~64s on the m3ultra MPS):
- FLUX ignores "seamless tiling" (seam_error 3.7-17.9); a 4-way cosine
  partition-of-unity blend of the four half-rolls fixes it exactly -> 0.87-1.32
- levels-normalised the pack to one exposure (means were 0.18-0.32); these are
  detail maps multiplied into a biome tint, so per-prompt exposure read as a
  broken tint rather than as dark tissue
- prompt-kit experiment rejected + recorded: PROCITY's "uniform coverage" clause
  in the STEM cured centred subjects but flattened the pack; framing words now
  live only in the two subject prompts that needed them

Audio (1 bed + 4 sfx, 4.2s render, 0.61/10MB, ogg+m4a dual-ship):
- bed-esophagus 24.000s, loop seam 0.32 (wrap step 3x smaller than inner step)
- cascaded lowpass poles: one-pole at 900Hz left 16kHz only ~25dB down = hiss
- rewrote the spectrogram sheet (per-clip peak, log freq) — the first one was a
  saturated rectangle, and evidence you can't read is not evidence

assets.js: miss ledger + misses() — Lane A found that a drifted slug falls back
procedurally forever with no error. Each distinct miss now announces itself.

Also: shot_sink.py (canvas -> docs/shots/laneD, correctly named) and a dev
texture viewer that imports the stub world read-only for the eyeball law.
