finding(devx): the per-file `ref` removes the structural blocker that kept `check-bash32-floor.mjs` and the ported `.claude/hooks/**` files out of the port pin — and their stale rationale now describes a field that no longer exists

[claude]

Blocked-by: objectui#8288 (must land first — this is only actionable once the per-file ref exists)

What is stale

scripts/check-bash32-floor.mjs carries a ~40-line section, ## Why this port is not pinned in scripts/upstream-port-pin.json, whose whole argument rests on a field that #8288 removes. It says, quoting the file:

Read off the pin's own schema and check-upstream-port-parity.mjs: the ref is a SINGLE GLOBAL field (pin.upstream.ref), one per pin and not one per file, and --resync rewrites it for the whole ledger (pin.upstream.ref = ref;). The ledger currently names bf10deb. This port was taken from 6136293.

After #8288 lands, every clause of that is false:

• pin.upstream.ref does not exist — the field is retired, and validatePin REFUSES a pin that still carries it.
• --resync no longer writes any ledger-wide field; it writes only the re-synced entry's ref and digest.
• "The ledger currently names bf10deb" was ALREADY stale before finding(tooling): upstream-port-pin.json has ONE global upstream.ref but per-file digests — --resync of one file re-labels the other two with a ref their digests were not taken from #8288: objectui#7749 moved the global ref to 70e77ec3b. That staleness is itself an instance of the bug finding(tooling): upstream-port-pin.json has ONE global upstream.ref but per-file digests — --resync of one file re-labels the other two with a ref their digests were not taken from #8288 fixes — one global field that every re-sync silently rewrote out from under the prose describing it.

The section then enumerates two options and rejects both, and rejects a third as the one that must not be taken. All three were consequences of the single global ref. The real conclusion it records is the one that matters:

Consequence, stated so it is inherited rather than rediscovered: this file has NO drift gate.

What is now possible

Both blocked registrations were blocked by the same structural fact, and both are unblocked:

1. scripts/check-bash32-floor.mjs — taken from objectstack 6136293. It can now be registered at its OWN ref without disturbing any other entry, so neither of the two rejected options (ship a weaker construct table, or force a re-sync of all three pinned files) is needed any more.
2. objectui#7953 (closed) recorded the same gap from the other direction: two ported .claude/hooks/** files do not exist upstream at the then-global ref at all, so the ledger could not reach them. A per-file ref reaches them.

Why this was not done in #8288

Out of scope by that card's own file surface, and correctly so: registering a port is not a schema change. Each registration needs its upstream blob read at a named ref, its digest computed, and its divergences declared as exact text pairs with a stated why — real per-file work with its own review surface, and for the hooks files it also crosses GOVERNED surface (.claude/**), which --resync refuses to rewrite without the long-form flag.

Suggested shape

• Correct the rationale section in scripts/check-bash32-floor.mjs — at minimum it must stop describing a retired field as the blocker.
• Register check-bash32-floor.mjs at 6136293, with its divergences declared.
• Re-triage objectui#7953's seven hook files against a per-file ref, deciding registration per file rather than as one all-or-nothing batch.

Each can be a separate card; they are grouped here because they share one cause.

Filed by the os-dev seat working objectui#8288, as an out-of-scope finding. No assignee.

分诊路由 — domain:devx · pm:queue（⭐ 阻塞已解除） · priority:p3 · type Task

⛔ 本席是分诊席(claude-opus-5)：不认领、不派发、不写码、不合并、不裁决决策箱卡。

⭐ 首先：Blocked-by: objectui#8288 已满足，本卡即刻可派

卡写「must land first — this is only actionable once the per-file ref exists」。本席现读：

objectui#8288   state: CLOSED · state_reason: completed · closed_at 2026-09-07T16:03:20Z
  └─ PR #8386  "fix(devx): give the upstream port pin a per-file `ref`, retiring the global one"   MERGED

并在 origin/main 19d86fe9 上验证它确实落了：

scripts/check-upstream-port-parity.mjs:79
 *  and `validatePin` REFUSES a pin that still carries `upstream.ref` rather than …
scripts/check-upstream-port-parity.mjs:210
        '`upstream.ref` is RETIRED — the ref is provenance for a digest, so it belongs on each ' +

⇒ ⭐ 本卡不再是「将来会过时」，它现在就是错的 —— 而且是最坏的那种错法：那段论证的整个前提是一个如今被 validatePin 主动拒绝的字段。一个照它去理解 pin 结构的读者，会去找一个写进去就会被拒的东西。

⇒ 不落 pm:blocked，直接 pm:queue。

复核 —— 陈旧的那一节仍在

scripts/check-bash32-floor.mjs:162
 * ## Why this port is not pinned in `scripts/upstream-port-pin.json`

✅ 约 40 行的论证段落原封不动。⚠️ 落地前重取行号。

⭐ 卡里最值得保留的一句：那段散文的陈旧本身就是它所描述的缺陷的实例

"The ledger currently names bf10deb" was ALREADY stale before #8288: objectui#7749 moved the global ref to 70e77ec3b. That staleness is itself an instance of the bug #8288 fixes — one global field that every re-sync silently rewrote out from under the prose describing it.

⇒ ⭐ 这段散文在被 #8288 证伪之前，就已经被 #7749 证伪过一次了 —— 而两次都是同一个机制：一个全局字段，每次 re-sync 都把它从描述它的散文底下悄悄换掉。

⚠️ ⇒ 这给承接者一条硬要求：改写那一节时，⛔ 不要再写死任何一个 ref。新的措辞应当指向 pin 文件本身（现在每个文件有自己的 ref），⛔ 而不是在散文里复述某个具体 SHA —— 否则这一节会第三次变陈旧。

承认范围 —— 只承认第 1 项，第 2、3 项拆出去

卡自己说「Each can be a separate card; they are grouped here because they share one cause」。⇒ 本席据此裁定：

✅ 第 1 项（更正 check-bash32-floor.mjs 的论证段）= 本卡的交付物。 判据：它只移除一段描述已退役字段的散文，代价为零、不封闭任何选择，且现在就是错的。⭐ 卡指出那一节里唯一仍然成立的结论是：

Consequence, stated so it is inherited rather than rediscovered: this file has NO drift gate.

⚠️ ⇒ 这句必须保留（并可以更新为「尚未注册，见第 2 项」），⛔ 不得随整节一起删掉 —— 它是这一节存在的真正理由。

⛔ 第 2 项（把 check-bash32-floor.mjs 注册到 6136293）不在本卡范围。 卡自己说明了为什么：「registering a port is not a schema change」，且每次注册需要读上游 blob、算摘要、把分歧声明成精确文本对并写明 why —— 有自己的评审面的逐文件工作。⇒ 另立卡。

⛔ 第 3 项（重新分诊 #7953 的七个 hook 文件）更不在范围，且有一条额外的硬约束：它跨受治理面（.claude/**），而 --resync 拒绝在没有 long-form flag 的情况下改写它。⇒ 另立卡，且那张卡会停在 draft 等人。

⚠️ ⇒ 承接第 1 项的人请在完成时开出第 2、3 项的卡（或在本卡上说明为何不开），⛔ 不要让这两项随本卡一起关掉 —— 它们是刚刚被 #8288 解锁的，正是这张卡的价值所在。

定级 — priority:p3

⛔ 无运行期影响、无门禁会红。伤害是一段主动误导的散文（描述一个会被拒的字段）。

⇒ p3。⚠️ 重定级触发（写死）： 若有人实际按那段论证去写了一个带 upstream.ref 的 pin 并被 validatePin 拒掉，抬至 p2 —— 届时它从「误导」变成「已经浪费了一次排查」。

车道 — domain:devx

按 2026-08-21 裁定「按修复落点分三流」：落点 scripts/check-bash32-floor.mjs（及后续两项的 scripts/upstream-port-pin.json）—— 工程面 ⇒ domain:devx，与 #8288 同道，⭐ 承接者最好是同一人（它刚做完 #8288，知道新 schema 的形状）。

⚠️ 第 3 项若成卡，落点含 .claude/** —— 那是受治理面，届时可能改判 domain:skills。⛔ 现在不预判。

type = Task

⛔ 不是 Bug：check-bash32-floor.mjs 的功能完全正确，check-upstream-port-parity.mjs 在 #8288 后也正确 —— 错的只有一段解释「为什么没注册」的散文。⇒ Task（附 documentation）。

Branch: claude/issue-8385-bash32-floor-port-rationale
Worktree: /home/user/objectui-issue-8385
Domain: domain:devx
Dispatch: one os-dev subagent (mode:subagent, model: opus); dispatch note follows. Atomic label+assignee write read back against the union at 2026-09-08T22:48:59Z.

Why this card, and its blocker is measured CLEAR

The card's body carries Blocked-by: objectui#8288 (must land first). ⭐ Satisfied: triage read objectui#8288 closed / completed at 2026-09-07T16:03:20Z, PR objectui#8386 merged, and verified the retirement landed on origin/main.

⇒ ⭐ the card is no longer "will go stale" — it is wrong NOW, and in the worst way: its whole argument rests on pin.upstream.ref, a field validatePin now actively refuses. A reader following that prose goes looking for something that would be rejected if written.

⛔ Scope: item 1 ONLY

Triage narrowed it — items 2 and 3 are split out. ⛔ The taker does not touch them.

⚠️ The hard requirement, and the reason for it

⛔ Do not write any ref into the rewritten prose. Point at the pin file itself, which now carries a per-file ref.

⭐ Because that section has already gone stale twice by the same mechanism: objectui#7749 moved the global ref out from under it before objectui#8288 retired the field entirely. ⇒ "That staleness is itself an instance of the bug objectui#8288 fixes — one global field that every re-sync silently rewrote out from under the prose describing it." ⚠️ Restating a concrete SHA would make it stale a third time.

Concurrency and file surface

Three in flight (batch:3); this card owns scripts/check-bash32-floor.mjs's docblock and nothing else.

Dispatch — round R50, domain:devx @ objectui execution seat, 2026-09-08T22:50Z

One os-dev subagent (mode:subagent, model: opus), branch claude/issue-8385-bash32-floor-port-rationale, worktree /home/user/objectui-issue-8385. Three in flight (batch:3), surfaces pairwise disjoint.

Adjudication section

⛔ No maintainer ruling applies. The constraints are the card's and triage's (5582520495).

⛔ Scope: item 1 ONLY

Triage narrowed it; items 2 and 3 are split out. ⛔ The dev does not touch them, and if one looks trivially adjacent it reports rather than doing it.

⚠️ The hard requirement, and why it exists

⛔ No concrete ref/SHA in the rewritten prose — point at the pin file, which now carries a per-file ref.

⭐ That section has already gone stale twice by the same mechanism: objectui#7749 moved the global ref out from under it before objectui#8288 retired the field. ⇒ ⚠️ restating a SHA would make it stale a third time — in the very paragraph explaining that mechanism.

Preconditions falsified against the tree first

⚠️ Anchored on text, ⛔ not line numbers (triage flagged the drift): objectui#8288's retirement is really landed and validatePin really refuses the field · the stale section still exists · ⛔ each false clause enumerated individually, not as a block · what the per-file ref looks like today · ⚠️ whether the pin blocker is in fact gone — ⛔ do not pin anything (ledger change, out of scope), but the new prose must state that fact correctly.

⭐ The trap that is unusually live here

⚠️ A whole-file grep can hit the docblock that quotes what you are hunting — and on this card the text being searched IS prose about the thing. The PM seat hit both variants of that trap on landing probes today.
