skills(pm-dispatch): hard serial across rounds applies to the same claimed REGION, not the same file — SKILL.md :441 and its core-rules twin, one word each

Clause-②: no

The 候选与批次 section gave two opposite serial rules for every shared path
but `.objectui-sha`: :437 (「共享其它路径是普通并发,后落地方解冲突」) and :441
(「同文件单跨轮硬串行」). Ruling 甲 narrows :441 to the REGION the claim
declared: hard serial across rounds only where the two claims' declared file
surfaces overlap; the same file in different regions is ordinary concurrency
and the later lander resolves the conflict — which is what :437 already says
for every non-single-writer path once :441 stops claiming the whole file.

- SKILL.md :441 — 同文件 → 同区域 (107 B → 107 B); the 「延后不是搁置…」 half
  stays byte-verbatim; :437 untouched; `SINGLE_CLAIM_PATHS` stays the only
  whole-file single-writer set; 813 / 813.
- references/core-rules.md :105 — 同文件硬串行 → 同区域硬串行 (119 B → 119 B),
  the twin SKILL.md:44 orders; 151 / 151.

The ruling's own :441 sentence (「同区域(认领申报的文件面重叠)单跨轮硬串行;
同文件不同区域是普通并发,后落地方解冲突。」) measures 123 B alone and 198 B
with the deferral half, against the ratchet's 120-byte line cap and a 813-line
ceiling with zero headroom; measured red on the gate in both one-line and
two-line forms. The one-word narrowing is the rendering that keeps the
deferral half verbatim, net 0, no script, no gate — the PR body carries the
measurements and the alternative (a ceiling raise under the ratchet's own
maintainer exit).
