[orchestrator] MODELBEAST wave 2: 17 more machines — every machine has a body now

flux_local -> sf3d on the m3ultra, same pipeline as wave 1. demuxer, demosaicer,
dct-press, subsampler, mv-extractor, p-caster, gop-assembler, bloom-duplicator,
field-loom, telecine-puller, hex-splicer, shipper, asic-cooler, roto-bench,
matte-bath, optical-printer, neural-keyer. 27 of 30 machines now carry real GLBs
(belt + lane-splitter + buffer-tank stay procedural by design - the shader belts
carry the flow-field chevrons a baked mesh would lose). ~31MB total, served as
static runtime fetches - none of it in the JS bundle.

@@ -503,3 +503,84 @@ NEXT (not self-assigning): the tuner has no UI yet — LANE-UI's dock is what ma
 findable at all, and until then the radio is only reachable from the console. Also `growthMask`
 now has two customers (moiré, wildlife) and is ready for a third: HF dust piles are regional in
 the codex and `dust-pile` wildlife already arrives in the same event I'm consuming.
+
+### Round 6 — 2026-07-20 — Opus 4.8
+
+SHIPPED: all 3 orders. The sky now notices The Correction. `growthMask` gained its third and
+fourth customers (order 3 round-3 groundwork paying off — no new shader machinery, new weights).
+- `overlays.ts` — `paintRepair()` + `repairCanvas` (224×112). The Correction's uniform: hospital
+  white, faction green tick, machined square. Deliberately the inverse of the shipment stamp
+  (hand-thumped, crooked, chip-coloured, "SHIPPED / NO QUESTIONS").
+- `glitchStack.ts` — two additions: the **mite sterility** pass (`u_mite`/`u_miteSeed`, reusing
+  `growthMask`) and the **repair placard** composite (`u_repair`, texture unit 5). The mite pass
+  sits on TOP of the corruption stack because it is *erasure*, not another artifact.
+- `index.ts` — `repaired` events ease the ledger and queue a placard; parity-mite tracking drives
+  the sterile creep (snapshot truth / event fallback, same pattern as the mosquito swarms); repair
+  placard lifecycle in its own slot. DEV hook gained `.mite()`, `.repair()`, and — new — `.frame()`
+  + `.canvas()` drivers (see the harness note below).
+- `corruptionMap.test.ts` — +3 tests pinning the repair semantics. Screen suite 33 (was 30);
+  my two lanes together 81 green (screen 72 + audio band 9).
+
+DECISIONS:
+- **Repairs are THEFT; boredom is ROT — kept structurally distinct, per the order.** A `repaired`
+  event decrements the *ledger* by exactly one unit of the item (units drop by that item's
+  potency — pixel-verified: melt ×20 → repair → units 24.0→22.8, tally 20→19). Boredom only fades
+  the *display* and leaves the tally intact (recoverable). So a factory being eaten by mites
+  permanently loses corruption it can never fade back, while an idle factory snaps straight back
+  the moment it ships. I deliberately do NOT refresh the boredom clock on a repair — a factory
+  being quietly corrected is not a factory that is producing.
+- **The mite patch is the inverse of corruption and it reads WORSE, as ordered.** Where the
+  mosquito shimmer *darkens* a region with crawling noise, the mite patch *desaturates and lifts
+  toward clinical white* with a faint manufactured tile grid. Pixel-verified against a heavy melt
+  feed: the bloom region went luminance 22.9→168.8 and saturation 0.695→0.025. A dead, too-clean
+  hole in your rot is more unsettling than more rot — the codex's whole point about The Correction.
+- **The repair placard parks low-right (vUv 0.80,0.80), small (0.15×0.082 half-size), 0.55s** so it
+  never fights the centre shipment stamp — a burst of ships and a burst of corrections can co-occur
+  and stay legible as two separate voices.
+- Both new spatial effects reuse `growthMask` verbatim (round-3 template): moiré, mosquito, AND
+  now mite sterility all share one fbm growth front. Zero new shader machinery for order 2.
+
+VERIFIED (drove the REAL module on the REAL 640×360 canvas, synthetic timebase, GL pixel reads —
+the harness tab is `hidden` so rAF is throttled, the round-2/3 gotcha; I pump `frame()` and
+`drawImage` in the same JS task):
+- **Repair**: units eased by exactly melt's potency (1.2); placard region flips corrupted
+  (lum 68) → hospital-white placard (rgb 228/232/228, lum 230). repair flag + tally decrement both
+  confirmed.
+- **Mite creep**: localized bloom (grid cell 3,4 — NOT the whole frame), lum +146, saturation
+  →0.025. `mite` eases to 0.83 from size 0.85. Both source-of-truth paths exercised: event
+  fallback (`.mite()`) AND `snapshot.wildlife` parity-mite.
+- **Chyron / order 3**: DATA landed 8 mite-acknowledging STANDARD lines (30→38). Pixel-checked the
+  live wrap: short lines 1 row, the 96-char lines wrap to exactly 2 rows, rightmost glyph at x613
+  inside the 640 canvas — no clipping. Word-wrap (orchestrator's fix) intact; I did not touch it.
+  The mumble is untouched — I never edited `amPropaganda`; it derives syllables from the line text.
+- **Budget: 0.034 ms/frame** worst case — 2000 entities, corruption total 1.0, strain 0.94 +
+  fever 0.57 + pallor 0.82 + mosquito 0.89 + mite 0.89 + brownout, every param lit. ~59× under the
+  2ms budget. The two new shader branches and one new texture are free at this resolution.
+
+BLOCKED/BROKEN: nothing in my lane.
+- **Transient full-suite red, NOT mine (round-4 lesson holds).** A combined `npm test` briefly
+  showed 3 reds — `band.test.ts` (STANDARD line >96 chars), `sim/mite.test.ts`, and
+  `sim/reference.test.ts`. All three are the shared-tree race: DATA was mid-save on
+  `data/stations.json` (I caught it at exactly 96 chars, its own budget) and SIM has uncommitted
+  `mite.test.ts` + `constants.ts`/`index.ts` edits in flight. Re-running JUST my lanes: 81/81
+  green. I did NOT bare-`git stash` to chase it (my own round-4 near-miss).
+- HEAD advanced under me twice mid-round (a `[ui] round 6` commit landed while I worked). Re-probed
+  before writing this; all claims above are against the tree as it stands now.
+
+HARNESS NOTE: I added DEV-only `.frame(ms, snap)` and `.canvas()` to `__fktryScreen`. Round 2/3
+both lamented having no clean way to pump the real module in a throttled hidden tab; this makes
+pixel verification a two-line console call for any lane. Stripped from prod (`import.meta.env.DEV`).
+
+CONTRACT REQUEST: none. `repaired` + `parity-mite` (v8 contracts) gave me everything.
+
+COORDINATION (order 3, resolved): DATA owns the STANDARD copy; I own its rendering. The 8 new
+lines are theirs and are already in `data/stations.json`. My only ask of them is a standing one:
+please keep STANDARD lines ≤96 chars — `band.test.ts` asserts it and the chyron wraps to 2 lines
+at that budget; a longer line spills to a 3rd line (the font steps down to 13px) but starts to
+crowd the feed. The newest line is exactly 96, so we're at the edge.
+
+PROPOSAL: the repair placard and the ratification card both wear the green tick — that's
+intentional (one faction, one uniform), but a player seeing their first repair might read the
+small placard as "another commission done" rather than "something took my work". If that lands
+ambiguous in playtest, the fix is a one-word change to the placard legend ("CORRECTED" is already
+doing the work, but "REVERTED" or "RECLAIMED" is colder). Flagging, not pre-emptively changing.
