platform-checklist step (2): re-author the 1,647 source citations as symbol anchors and add a resolver that reds on an absent symbol

[claude]

Step (2) of the two-level remedy #13482's triage ruling ordered. Step (1) — stripping the rotting
:NNN suffixes — landed in PR #13786; this is the half that was deliberately deferred, and it is
filed so the deferral cannot quietly become an abandonment.

What the ruling said

1. ⭐ 先做廉价的:去掉 :NNN 后缀 …… 零新机械、立即止血。
2. 再做符号锚 + 解析器(与 [worklist] Migrate liveness line citations to symbol anchors — census: 117-173 of 298 live line-cited pairs fail key-proximity at line granularity today #13003 为 sibling ledger 选的同一形状):引用符号而非行号,并给
   checklist 门一个解析器,被引符号不在被引文件里即红。

⛔ 顺序不可颠倒:第 2 项是新验证面(注册 + self-test + workflow + baseline),而第 1 项今天就能把假
「已验证」信号去掉。

Step (1) is done. The citations now carry file + symbol and no line number, so nothing rots — but
⛔ nothing checks that the cited symbol is actually in the cited file either. That is this card.

The size, measured

From #13786's census, produced under a defined criterion rather than a grep:

1,647 source-line citations   ·  260 items  ·  18 files
(1,034 file-anchored, 613 bare)

That census is why the two steps were split: folding a 1,647-citation re-authoring into a new
verification surface would have made both unreviewable, and it would have inverted the ruling's own
reason for the ordering — step (1) removes a false "verified against source" signal, step (2) adds
a new signal that must itself be proven.

⭐ The shape is already in the gate, so this is not a design question

scripts/check-platform-checklist.mjs already resolves a structured pin —
enumSource {file, export, expect} — checking file existence, export presence and member count.
⇒ The resolver for symbol anchors is a known quantity built on an existing mechanism, ⛔ not a new
invention. #13003 chose the same shape for the sibling ledger under packages/spec/liveness/; read its
implementation for the shape, ⛔ but do not reuse its gate — that is a different file family with its
own gate, which is why #13482 was not merged into it.

What this card owes

• Re-author the citations into a structured symbol anchor;
• a resolver that reds when a cited symbol is absent from the cited file, with its own
  registration, self-test and baseline;
• and the two-direction pinning this gate's existing checks use — a firing case and a silent
  neighbour for each rule.

⚠️ Known context the implementer needs up front

pnpm check:platform-checklist is not CI-wired, by a standing maintainer decision recorded in
lint.yml; the visibility gap is carded separately as #11730 (pm:awaiting-maintainer). ⇒ A red
from this resolver reaches whoever runs the gate, ⛔ not every PR. State that plainly in the PR
rather than implying reach the check does not have — overstating a new check's reach would reproduce
the very defect this family is closing: a signal that reads as verified while pointing at nothing.
⛔ Do not touch the CI wiring here; that decision is the maintainer's and #11730 holds it.

Provenance

Deferred half of #13482's ruling. #13786's dev searched all 384 open issues (REST list + local grep on
symbol-anchor / platform-checklist / citation / line-number keywords) and found no existing
step-(2) card, then correctly left the sequencing to the PM rather than filing it as its own find.
Filed unassigned and ungraded by the domain:devx PM seat — domain:*, priority and type are
triage's field.

⭐ 这是本席 R+70 在 #13482 上那条裁决的第二步,而它被立成了卡 —— 正是裁决要求的形状:「⛔ 顺序不可颠倒」 加上一张卡,让延后不会悄悄变成放弃。第一步(去掉 :NNN 后缀)已由 PR #13786 落地。⇒ 裁决被完整执行,记名。

定级依据

p2 而非 p1:第一步已经把假「已对源验证」信号去掉了 —— 引用现在是 file + symbol,没有会腐烂的行号。⇒ 今天不再有人被一个指向错行的指针误导;缺的是主动检出(被引符号不在被引文件里时变红)。⇒ 从止血降为加固。

Task 而非 Bug:第一步之后没有虚假断言在流通;本卡是新增验证面。

⭐ 形状不是设计题,机械已在门里

卡指出得对:scripts/check-platform-checklist.mjs 已经解析一种结构化 pin —— enumSource {file, export, expect},检查文件存在、export 存在、成员计数。⇒ 符号锚解析器是在既有机制上扩一层,⛔ 不是新发明。

⇒ 派发令:读 #13003 的实现拿形状,⛔ 但不要复用它的门 —— 那是另一个文件族、有自己的门,而这正是 #13482 当初没有被并进 #13003 的理由。

⚠️ 实施者必须提前知道、且必须写进 PR 的一件事

pnpm check:platform-checklist 没有接进 CI,这是记录在 lint.yml 里的常设维护者决定;可见性缺口另有卡 #11730(pm:awaiting-maintainer)。

⇒ 这个 resolver 的红只到跑门的人,⛔ 不是每个 PR。

⭐ 卡的这句要求分诊逐字保留为硬约束:

State that plainly in the PR rather than implying reach the check does not have — overstating a new check's reach would reproduce the very defect this family is closing: a signal that reads as verified while pointing at nothing.

⇒ ⛔ 不得在本卡里碰 CI 接线 —— 那是维护者的决定,由 #11730 持有。

规模与交付

普查读数(#13786 产出,按定义的判据而非 grep):1,647 条源行引用 · 260 个条目 · 18 个文件(1,034 file-anchored / 613 bare)。

交付三件:① 把引用改写成结构化符号锚;② resolver + 自己的注册、self-test、baseline;③ 双向钉(每条规则一个触发用例 加 一个静默邻居)—— 这是该门既有检查已在用的形式,⛔ 不降标准。
