+## ROUND CLOSED (Fable) — **THE FLOOR IS LEVEL. All five items, all green, no tag.**
+
+`qa.sh --strict --matrix`: **7 passed · 0 failed · 0 warn · 0 skipped** · selfcheck **157,407**
+(+1,055 of A's new poster assertions, all green on the ruled street) · flags harness **0 fails
+/ 0 warns** · **MATRIX GREEN 10 towns × 7 gates**. Deliberately **no tag** — wave 0 levels the
+floor, it does not ship a version.
+
+**What actually changed, in one line each.** The kerb is footpath and it cost **+0 draws with
+triangles going DOWN** (A/B'd against HEAD on a second port; sum-of-draws identical at all 102
+walked steps). **14 posters stood in painted bitumen; 0 do now — and not one poster moved, the
+ground did.** The budget of record is **292/124,793**, and the 280-vs-191 fight was **camera
+bearing** (110 draws of spread; the audit took `DBG.teleport`'s default yaw 0, the worst
+bearing; the spike took a travel-facing yaw — both correct, different quantities). Two vacuous
+gates are dead: `smoke_tram` (green exactly where it was meant to look, because a named empty
+group satisfied it) and the poster clearance check (**the placer seats via `poleOffset`, which
+is derived from `roadWidth`, and the gate asserted against `roadWidth/2` — the same function
+agreeing with itself, the R27 trap inside the file whose header explains the R27 trap**). The
+chunk seam is subscribable at last — the producer was fine; **`chunks.ctx` was never returned**,
+so a consumer holding `PROCITY.chunks` had nowhere to attach.
+
+**The round's own lesson, recorded.** B's first cut passed every number — +0 draws, posters
+clear, zero errors — **and painted every intersection shut.** A screenshot caught what the
+metrics could not. Fixed by lifting the carriageway over the footpath at junctions, verified on
+Katoomba's worst 4.3° corner. *Green metrics over a wrong world is this project's oldest
+failure mode and it does not care which epoch it is.*
+
+**Two lanes, two independent methods, one number.** A counted 14 plan-side (node, over the
+plan, by offset); F counted 14 paint-side (browser raycast, over B's geometry, classified by
+**material identity** so it cannot drift when B edits). Both flip to 0 on the ruled street and
+both fire at exactly 14 under `?verge=0`. F's two **detector controls** are the load-bearing
+part: "0 posters on road" is a sentence about nothing unless the classifier is shown saying
+*road* AND *footpath* on the same boot.
+
+**Cross-lane corrections that landed mid-round** (the shepherd's whole job): A's measurement
+killed three literals in Fable's brief — `lane`'s band is `[4,4]` on 56 real edges, not the
+synthetic `[2,2]`; the "9 m band / 18 m of main" figures are synthetic-only (a real main is
+24 m ⇒ 7 m, and `side`@12 is **72% of the corpus** at 3 m). B confirms it would have shipped
+the `[2,2]` assumption otherwise. F's allow-list mechanism corrected Fable's other literal:
+"four GLBs + same-origin" **would have gone green straight through the R36 breach**, so the
+list is derived from `git ls-tree` at gate time — and per this round's ruling the authority tag
+moved `v2.0 → v2.1`, which git made surgical (`git diff v2.0 v2.1 -- web/` is the audio pack
+and its wiring, zero other assets, zero deletions).
+
+**Carried to the v8 debt ledger (filed, not smuggled):** A's D1–D4 (three `chunkIndex`
+divergences · four `isOpen` implementations, A's canonical export with **zero importers** ·
+two registries, which is why gig venues have worn op-shop signage since R13 · A's own
+nearest-edge/arcade poster-gate hole, costed at 11 of 26 town gig goldens and deferred so this
+round's "did the kerb move a golden?" stays a clean **no**) · the town-matrix's budget column
+is **bookmark numbers**, which this round proves under-report a walked-and-turned frame by
+~120 draws — a regression signal, not the budget of record · `?r=3` breaches at **307 draws**
+through an ungated override · *should `?classic=1` show the town selector at all?*
