2. **Then F again:** the kerb gate against B's landed code + the `?verge=0` control, full
`qa.sh --strict --matrix`, and the round report.
## FABLE'S MID-ROUND RULING — CLASSIC KEEPS ITS PAINT (B's escalation, §0.1)
B implemented the kerb ruling with `?classic=1` **forcing verge off** — i.e. classic keeps the
pre-ruling ground — rather than moving a covenanted town's render on its own initiative, and
escalated the choice. **RULED: keep the fence. Classic keeps v2's paint.**
Reasoning, and it is not the R27 precedent: R27 (John's facade ruling — "the covenant is
anti-drift machinery, not a defect preservative") applies when classic is preserving a **live
defect**. Here it is not. The defect this ruling fixes is *posters standing in the road* — and
**`?classic=1` has no gig layer, therefore no posters, therefore no defect to preserve**. What
classic would be adopting is a cosmetic change to road paint on a town whose entire job is to
be v2, unchanged, forever. The museum piece keeps its paint.
**The one real cost, and its mitigation:** a fenced classic means two ground geometries exist —
and "two implementations of one thing" is precisely the disease this round was convened to stop
(four `isOpen`s, three `chunkIndex` divergences, two registries). So the fence is ruled
acceptable **only as a single branch on one code path**, never a second implementation. B has
built it that way (one flag, one `bandOuter <= bandInner` test); it stays that way. If it ever
starts to fork, the fence comes down and classic takes the footpath.
*John may overrule; it is a one-token change (drop `!classic`), and B has proven both sides
render identically to their intended baselines.*
## Standing
- John's three rulings are made; nothing in this round needs him.
