skills(objectstack-data): re-lock field-types.md token ceiling, drop SKILL.md index blurb

[os-musk]

Fixes #16374

What

Both PRs that were shrinking skills/objectstack-data/rules/field-types.md have merged
— PR #16187 (the two tree rows, −11 tokens) and PR #16369 (the ASCII decision tree
deleted, −536 tokens). This PR executes the ruling on PR #16369's second open question:
a lowered ceiling is the ratchet's ordinary direction and a seat's re-lock, not a
maintainer ruling.

• scripts/check-skills-token-ratchet.mjs: the ceiling for
  skills/objectstack-data/rules/field-types.md re-locks from 3584 to 3032 — the
  count the gate itself measures on origin/main (de0bcdd4), not a computed number.
• skills/objectstack-data/SKILL.md: the index line for that file drops the phrase
  "with decision tree" (three words, not four as the issue text says — the ASCII block
  it referred to no longer exists either way) so the line reads "All 49 field types and
  configs".

Nothing else in either file moves.

Line budget (measured, not computed)

file	before	after
rules/field-types.md — measured tokens	3032	3032 (unchanged)
rules/field-types.md — ceiling	3584	3032
rules/field-types.md — headroom	552	0
SKILL.md — measured tokens	10004	9999
SKILL.md — ceiling	10009 (unchanged)	10009
SKILL.md — headroom	5	10

Package-level (skills/objectstack-data/**, sum of every tracked file's measured tokens,
authored + generator-owned): 37901 → 37896 (−5, from the SKILL.md edit only —
field-types.md's measured count is unchanged, only its ceiling moved).

Whole-bundle total the gate prints (bundle total (whole shipped tree)):
150527 → 150522 (−5).

Acceptance (all measured on this branch, not --self-test alone)

• node scripts/check-skills-token-ratchet.mjs --self-test — exit 0 (64 cases).
• node scripts/check-skills-token-ratchet.mjs (live) — exit 0; the file's line now
  prints ... is 3032 tokens (ceiling 3032; headroom 0).
• node scripts/pm/check-governed-merges.mjs --test skills/objectstack-data/SKILL.md scripts/check-skills-token-ratchet.mjs — exit 3: skills/** ×1 governs the whole
  PR (skills/objectstack-data/SKILL.md); the ratchet script itself is not on the
  register — one PR, one regime, as the acceptance criteria call for.

Merge-tree probe (driver-less bare clone, no merge.os-regen.driver registered)

• This branch vs fresh origin/main (de0bcdd4): clean, write-tree succeeded, no
  conflicts listed.
• Sibling in-flight PR docs(skills): teach the calendar-hours rule where a hook stamps a deadline #16591 (flight D, skills/objectstack-data/references/data-hooks.md
  — a disjoint file in the same package) vs this branch: clean, write-tree succeeded, no
  conflicts listed.

Serial preconditions re-checked

• PR skills(objectstack-data): the tree rows state the landed reference contract #16187 and PR docs(skills): drop the duplicated ASCII field-type decision tree from objectstack-data rules #16369 are both merged on origin/main (read by squash subject).
• Blocked-by: #16324 is discharged (skills(objectstack-data): rules/field-types.md carries a ~1800-byte ASCII decision tree that duplicates the docs' mermaid page, in a file 17 tokens under its ceiling #16324 closed with PR docs(skills): drop the duplicated ASCII field-type decision tree from objectstack-data rules #16369).
• skills(objectstack-data): the tree rows in rules/field-types.md and rules/relationships.md state the landed reference contract — optional, and the object's own name when present (#14892 follow-up) #16083 (the tree-row follow-up that fed PR skills(objectstack-data): the tree rows state the landed reference contract #16187) — re-read: CLOSED / COMPLETED.

维护者速读(草稿)

改了什么 — 把 rules/field-types.md 的 token 上限从 3584 重锁到 3032(门禁实测值,不是算出来的),因为压缩这份文件的两张 PR(#16187、#16369)都已合入,上限跟着落地字节数往下收。同一 PR 里,SKILL.md 索引那一行删掉"with decision tree"这个短语,因为它指向的 ASCII 决策树段落已经不存在了。

为什么改 — 棘轮的正常方向就是"降到落地计数",不需要维护者裁决,是席位自己就能执行的常规操作;裁决已经在 PR #16369 验收时做过一次了,这次只是照办。

风险与代价(含回滚) — 风险很低:改动只碰这两处,门禁(自测 + 实况)都绿,check-governed-merges --test 按预期红成 exit 3(governed surface,需要人工合并)。回滚方式是把这一个 PR revert 掉,上限与索引行都恢复原样,不影响其它文件。

席位意见 — (留空,由验收席位在 ACCEPT 时填写)

你要做的 — 这是 governed surface(skills/**),按规矩人工合并,不走 auto-merge / 合并队列;skip-changeset 已经打上(这个 PR 不发布任何包)。

维护者速读(终稿 · skills 席,2026-09-07T12:1xZ)

• 改了什么:rules/field-types.md 的 token 上限从 3584 重锁到 3032 —— 门禁在 main 上实测的落地值;skills/objectstack-data/SKILL.md 索引行删掉 "with decision tree" 三个词(它指的 ASCII 决策树已随 PR docs(skills): drop the duplicated ASCII field-type decision tree from objectstack-data rules #16369 删除)。两处,别的不动。
• 为什么改:压缩这份文件的两张 PR(skills(objectstack-data): the tree rows state the landed reference contract #16187、docs(skills): drop the duplicated ASCII field-type decision tree from objectstack-data rules #16369)都已合入,棘轮的常规方向就是降到落地计数 —— 这是席位自己可执行的重锁,PR docs(skills): drop the duplicated ASCII field-type decision tree from objectstack-data rules #16369 验收时已裁过一次,这次照办。
• 风险与代价(含回滚):零运行时、零发布(skip-changeset);该文件余量归零,下次要加内容得先删等量。回滚 = revert 一个 commit。
• 席位意见:席位在 head 1e1ff820 的分离副本上亲跑了 token 棘轮(自测 64 例;实况打印 field-types.md is 3032 tokens (ceiling 3032; headroom 0),data 包 SKILL.md 10004 → 9999),diff 只有那一行上限与那一行索引,对 origin/main ac9376a7 的 merge-tree 干净,受管判定 skills/** ×1。CI 32 项 12:09Z 无红。建议直接合并。
• 你要做的:人工合并本 draft PR(受管面不进合并队列)。
