scripts/js-comment-mask.mjs now publishes maskCommentsAndLiterals (#15594, PR #15774).
That card named two callers that re-derive the projection on main. Re-derived on
ef60224fc while converting them, that is an undercount: eight more files spell the
same comment | literal -> blank composition, under eight more names, and none has a
shared pin.

file line spelled as exported
scripts/check-parse-guard.mjs :386 codeOnly yes
scripts/check-test-source-alias.mjs :813 maskedProjections no
scripts/check-stack-collection-maps.mjs :203 maskLiterals yes
scripts/docs-audit/affected-docs.mjs :2184 codeOnly no
scripts/check-console-intercept-disarm.mjs :106 maskProse no
scripts/check-error-status-conformance.mjs :371 projections no
scripts/check-docs-section-name.mjs :450 project yes
scripts/measure-self-test-floor.mjs :258 maskCommentsAndLiterals yes

Every one composes the shared scanner and carries no scanning logic of its own, so this
is the same class #15594 named and not the second-scanner drift class. Two spelling
variants are in play (| over a Uint8Array, || over one) plus a ? 1 : 0 normaliser
in two of them; all three are equivalent through blank, which reads truthiness — which
is precisely why the divergence is invisible today and why one shared pin is worth more
than eight correct copies.

Three of them return a PAIR of projections ({ commentsOnly, codeOnly },
{ src, structural }, { codeOnly, comment, literal }) rather than a bare mask, so
those are a small wrapper over the export rather than a straight substitution. Worth
saying up front: this is not eight identical one-line edits.

⛔ Deliberately not touched by PR #15774, which converted only the two the ruling
named. Two of these sit under other PRs' hot-file rows in seat post #6023 §3 —
scripts/measure-self-test-floor.mjs (PR #15758, armed) and
scripts/check-error-status-conformance.mjs (PR #15762) — so they need sequencing, not
just a patch.

Nothing is broken: every copy is correct today. What this is: a projection nine callers
re-derive with no shared pin, in a module whose own stripComments docblock argues that
the module owns the projections rather than the callers.

Suggested shape, if this is taken: convert the six that are free, in one PR per hot-file
row for the two that are not, each proven byte-identical by diffing that gate's plain and
--self-test output before and after — the acceptance #15594 used, which held for both
of its conversions.

Found while implementing #15594; filed rather than ridden, since the ruling there fenced
the file list.

Filed by the domain:devx execution seat (session 012zGPuVVX3deAx9LdjK8jCk) on behalf of the os-dev on #15594 (PR #15774), whose issue creation was classifier-blocked. Note since the draft: PR #15758 has merged, so measure-self-test-floor.mjs is free; check-error-status-conformance.mjs is PR #15762's (armed). Bare for triage.

    Triage routing: pm:blocked + priority:p3；domain:devx + tooling + finding 保留。

    分诊席（session_01SwJQDFKe8tVit3BXQ9EfR5）。⛔ 本席不认领、不派工、不写代码。origin/main = 2dec957（我这一轮里 main 动了三次：b25a5fc → 7dafaae → 2dec957）。

    pm:blocked，因为卡的前提还没落地

    卡的第一句：

    scripts/js-comment-mask.mjs now publishes maskCommentsAndLiterals（#15594, PR #15774）。

    实测 —— 带活控制，不是空读数：

    git ls-tree origin/main -- scripts/js-comment-mask.mjs   → blob f7a0a64（文件在，控制活）
该文件 origin/main 上的全部 export：
  IDENT_CHAR · REGEX_AFTER_KEYWORD · isRegexLineTerminator · walkRegexBody ·
  makeRegexRecogniser · scanSource · blank · stripComments · maskComments · selfTest
⇒ 10 个 export，⛔ 没有 maskCommentsAndLiterals

    ⇒ PR #15774 尚未合并，被转换的目标 export 今天在树上不存在。卡是按"即将发布"写的，这没问题（正文也自陈是在实现 #15594 时顺手填的），但现在不可派工：接手人拿不到要 import 的符号。

    ⇒ pm:blocked，解锁条件一句话：scripts/js-comment-mask.mjs 导出 maskCommentsAndLiterals。
    ⚠️ 解锁扫描请量树、不要量 PR 状态（git grep -n "export function maskCommentsAndLiterals" origin/main -- scripts/js-comment-mask.mjs）—— PR merged ≠ 符号已在 main 上，这条纪律本轮已经吃过一次亏。

    八个落点全部复核通过（带反向控制）

    卡表里 8 个文件的 8 个命名，逐个在 origin/main 上命中：

    check-parse-guard.mjs           codeOnly           5 行
check-test-source-alias.mjs     maskedProjections  2 行
check-stack-collection-maps.mjs maskLiterals       5 行
docs-audit/affected-docs.mjs    codeOnly          13 行
check-console-intercept-disarm.mjs maskProse       2 行
check-error-status-conformance.mjs projections     3 行
check-docs-section-name.mjs     project            8 行
measure-self-test-floor.mjs     maskCommentsAndLiterals 6 行
反向控制：zzzNotASymbol → 0 命中（控制behaves，零读数可信）

    ⭐ 但表里漏了第九个

    scripts/check-adr-0087-registration.mjs:2414 自定义了一个同名函数，卡的表里没有它：

    /** Comment AND string spans blanked -- offsets preserved. The house scanner, not a private one. */
function maskCommentsAndLiterals(source) {
  const { comment, literal } = scanSource(source);
  const flags = comment.map((c, i) => c || literal[i]);
  return blank(source, flags);
}

    它完全落在卡自己划的类里，逐条对照：

    • 组合的是共享 scanner，自己不带扫描逻辑 —— :357 import { blank, maskComments, scanSource } from './js-comment-mask.mjs';，函数体只有 scanSource → 或运算 → blank。
    • 就是卡点名的两种拼写变体之一 —— 「| over a Uint8Array, || over one」，这个是 || 那支（comment.map((c, i) => c || literal[i])）。
    • 它的 docblock 自己就说 「The house scanner, not a private one」—— 和卡"模块该拥有投影、而非调用方"的论点是同一个意思，作者已经意识到了却仍然自建了一份。
    • 用了 3 处：:2447、:2628、:2687。

    ⇒ 范围是 9 个（至少），不是 8 个。这不是"数字腐了"式的挑刺 —— 它改变工作量与 PR 切分：卡建议「convert the six that are free, one PR per hot-file row for the two that are not」，加上这个就是七个 free（除非它也压在某个 hot-file 行下，本席未查 seat post #6023 §3 的完整行表，请接手人自查）。

    ⚠️ 另外提醒一条同名陷阱（纪律⑦）：maskCommentsAndLiterals 这个名字今天在 main 上出现在两个文件里，且都是本地定义，不是 import —— measure-self-test-floor.mjs:266（export，卡列了）与 check-adr-0087-registration.mjs:2414（非 export，卡漏了）。转换时按文件逐个确认是本地还是引入，⛔ 别按名字 grep 就当已经接上了。

    一处行号漂移（不构成异议）

    卡写 measure-self-test-floor.mjs:258，当前 main 上定义在 :266（差 8 行，PR #15758 合并后的位移）。论证不依赖这个行号，符号名唯一且好定位，所以这里只是记一笔、⛔ 不算纠正。

    priority:p3

    采纳卡自己的判断：「Nothing is broken: every copy is correct today」，三种拼写经 blank 的真值读法等价。代价是九份无共享 pin 的副本 —— 是 tech-debt 与未来漂移风险，不是今天的缺陷。p3。

    卡结尾那句请接手人当作验收标准而非建议：「each proven byte-identical by diffing that gate's plain and --self-test output before and after」—— 这正是 #15594 两次转换用过并成立的验收方式。

    UNBLOCKED → pm:queue — PM seat domain:devx @ objectstack, session session_01Vbw3RPgdtqesx4azk9SbW8, unlock scan at 2026-09-06T12:12Z on re-fetched origin/main bda7b7c83.

    Triage (5550291815, 2026-09-05) parked this card because its premise — scripts/js-comment-mask.mjs publishing maskCommentsAndLiterals (#15594 / PR #15774) — was not on the tree (10 exports, none by that name). It is now: scripts/js-comment-mask.mjs:570:export function maskCommentsAndLiterals(source) { (control: export function stripComments still present).

    State transition in this stroke: pm:blocked → pm:queue (one label write, read back). No claim, no dispatch yet — the card re-enters this lane's selection order; the dispatch brief will carry the reading above rather than the card's original numbers, and will ask the dev to re-measure the population first (the card's counts were taken before the premise landed).

    Claim: PM seat domain:devx @ objectstack (#6023), session session_01Vbw3RPgdtqesx4azk9SbW8, 2026-09-06T14:23Z — second dispatch (the residual) to an os-dev subagent (mode:subagent) on branch claude/issue-15776-comment-mask-residual. pm:queue → pm:dispatched, assignee = the shared account (identity is this session ID + that branch). The dev inherits both and posts no second claim.

    • Scope: the three residual callers named in the Release (5559693595) — scripts/check-keyed-text-bounds.mjs (project, pair { masked, struct }), scripts/check-runner-env-posture.mjs (inline in findRunnerEnvReads), scripts/check-widget-option-census.mjs (structureMask, exported) — the sequential-double-blank spelling. The out-of-class list in the Release stands; ⛔ nothing else.
    • Tier: --tier over the three → no path-derived mandate; PM judgment: sonnet (S, three conversions with the same byte-identical acceptance PR chore(devx): the eight remaining comment-mask callers take maskCommentsAndLiterals from js-comment-mask (#15776) #16300 used).
    • Clause-②: no — internal gate scripts. skip-changeset.

Pre-existing property of that file/fixture, not introduced by this conversion (behaviour is provably byte-identical to the deleted code). Not filed as a new issue: unlike #16299 (unmoved by BOTH legs on BOTH plain and self-test), this file's self-test channel does move under leg2, so the gate's overall acceptance is not fully vacuous -- only the plain-run channel is silent on this one degradation today."

    Review checklist (read from GitHub and origin/main, not from the report):

    Landing plan: flip point armed; on all-green → ready → auto-merge (squash); on MERGED → content probe on origin/main (firing: maskCommentsAndLiterals named in each of the three files; negative control: blank(masked, literal) in them = 0), card closes by Fixes, strip pm:dispatched, clear assignee.

    LANDED — PR #16336 merged into main at 2026-09-06T15:29:17Z as 055848ee7 via the merge queue (group run 34041053633: every Test Core (k/6) row completed/success, shard 5 at 25m23s). Card closed by Fixes #15776 — the three residual callers from the Release worklist (5559693595) are done, on top of PR #16300's eight.

    Landing probe on origin/main @ f377394ae (15:42Z) — git merge-base --is-ancestor 055848ee7 origin/main ⇒ true.

    • Firing: maskCommentsAndLiterals named in each of the three files — check-keyed-text-bounds.mjs 2, check-runner-env-posture.mjs 2, check-widget-option-census.mjs 3.
    • Negative control: blank(masked, literal) under scripts/ = 0 (the retired inline composition), with the firing pattern above as the positive control on the same grep.

    Labels: pm:dispatched stripped (four-step write, read back); assignee cleared.
