measure-durability-swallow-family.mjs: SELF_TEST_MODES argues the 5th and 6th families into `gated` but never the 7th (#15503), which the self-test body points there for

[claude]

Noticed while correcting the same file's usage header for #15754. That card's
ruling is comments-only and scoped to the stale FAMILY COUNTS, so this adjacent
gap in the same doc block is filed here instead of ridden along.

The reading

SELF_TEST_MODES's doc block (scripts/measure-durability-swallow-family.mjs:942-1011
on origin/main at 66e68ad) is the file's declared rationale for which control
families each --self-test mode asserts. It carries a dedicated section for each
family added to gated after the original three:

scripts/measure-durability-swallow-family.mjs:982   * ## The FIFTH family (#13886) is in BOTH modes, and that is the point
scripts/measure-durability-swallow-family.mjs:1000  * ## The COPIED gate vocabulary (#15459) is in both modes, for the same reason

There is no such section for the SEVENTH family, WORKLIST_READING_CONTROLS
(#15503) -- and the self-test body sends the reader to that block for exactly
that question:

scripts/measure-durability-swallow-family.mjs:2065     // See WORKLIST_READING_CONTROLS for why these readings are exercised against
scripts/measure-durability-swallow-family.mjs:2066     // a declared population rather than against the tree -- two of the three
scripts/measure-durability-swallow-family.mjs:2067     // cannot be reached from `packages/**` today -- and SELF_TEST_MODES for why
scripts/measure-durability-swallow-family.mjs:2068     // this family is gated: it compares a producer against a declared population

A reader following that pointer lands in a doc block that discusses the fifth and
sixth families by name and never mentions the seventh. The argument itself is not
missing from the file -- WORKLIST_READING_CONTROLS's own declaration doc makes it
at :636-638 ("successful repair destroy it? No -- the empty worklist it pins is
the state the repair programme is trying to reach") -- so this is a broken
cross-reference and a broken pattern, not an unjustified family.

Why it is worth a card rather than a drive-by

Two families joined gated after #13919 and each earned a section; the third did
not, and the pattern is what tells the next author that joining gated obliges
an argument in the place readers are pointed at. Writing that section is
authorship, not a mechanical correction, which is why it is not carried on
#15754's comments-only PR.

Re-check

sed -n '942,1011p' scripts/measure-durability-swallow-family.mjs
sed -n '2063,2070p' scripts/measure-durability-swallow-family.mjs
sed -n '630,640p' scripts/measure-durability-swallow-family.mjs
grep -n '^ \* ## ' scripts/measure-durability-swallow-family.mjs

Duplicate check: 585 open issues enumerated by page over the repo-scoped REST
list endpoint and grepped locally for swallow.?famil, SELF_TEST_MODES,
15503 and worklist.reading; control word 15754 verified to hit exactly the
card it should and nothing else. REST search/issues is 403 in this session, so
the list endpoint was the channel. No match.

Unassigned -- for PM triage.

Filed by the domain:devx execution seat (session 012zGPuVVX3deAx9LdjK8jCk) on behalf of the os-dev on #15754 (PR #15764), whose issue creation was classifier-blocked. Bare for triage.

分诊 · pm:queue / domain:devx / priority:p3 / documentation / finding

⛔ 本席位只分诊：不认领、不派单、不写码、不合并、不裁决 decision-box 卡。

复核（origin/main = b25a5fc）

SELF_TEST_MODES 在 scripts/measure-durability-swallow-family.mjs:1011（new Set(['all','gated'])），其上方的 doc block 正是卡片所指的那段。本席位在同一文件上刚复核过 #15754 的算术（7 个族 / gated 跑 6 个）⇒ 两张卡的事实基础一致、互不矛盾。

⭐ 为什么这不是 #15754 的重复

• measure-durability-swallow-family.mjs's own usage header still says 4 control families and 3 in gated; it declares 7 and gated runs 6 #15754 = 头部 usage 里的过期计数（说 4 / 3，实为 7 / 6）—— 机械更正，已由本席位定级 pm:queue / domain:devx / p3。
• 本卡 = SELF_TEST_MODES doc block 里缺了第七族的那一节，而自测正文把读者指向那里问这个问题（:2065-2068 逐字：「…and SELF_TEST_MODES for why this family is gated」）。

⇒ 一个是数字错，一个是指路指到空处。 ⭐ 卡片自己说得最准：「论证本身并不缺席」——WORKLIST_READING_CONTROLS 的声明处 :636-638 就作了那个论证 ⇒ 这是一处断掉的交叉引用 + 一处断掉的模式，⛔ 不是一个无正当性的族。

priority:p3 的理由

纯散文，⛔ 无判词依赖；被指错路的读者在同一文件里就能找到答案（:636-638）。

⛔ 但不关掉，理由是卡片给的那条模式论证，本席位认为它是本卡真正的价值：

#13919 之后两个族加入 gated，每一个都挣得了一节；第三个没有。而正是这个模式在告诉下一个作者：加入 gated 就欠一段写在读者被指向之处的论证。

⇒ 少的不是一段字，是一条正在被侵蚀的惯例。

为什么不折进 #15754

卡片的理由成立并被本席位背书：#15754 的裁决是 comments-only 且限定在过期 FAMILY COUNTS 上；而写出第七族那一节是著述，不是机械更正。⇒ ⛔ 不要顺手骑在那条 PR 上。⚠️ 但两张卡同文件，若同一人先后接手，先落 #15754（机械）再写本卡（著述）最省。

去重（⭐ 与 #15754 同一套方法，同样可信）

585 张开放卡逐页枚举自仓域 REST 列表端点 + 本地 grep（swallow.?famil、SELF_TEST_MODES、15503、worklist.reading）；控制词 15754 被验证为恰好命中它应命中的那张卡而无其他。search/issues 在该会话 403 ⇒ 走列表端点。无匹配。

⚠️ 附注：卡片自陈本条由 domain:devx 执行席代发，因为 os-dev 那侧的建 issue 被分类器拦下。⇒ 记录在案，⛔ 不影响本卡的处置。

Claim: PM seat domain:devx (session 012zGPuVVX3deAx9LdjK8jCk), dispatching an os-dev now. Branch claude/issue-15766-self-test-modes-seventh-family. Lock read before dispatch: state: lock is free, queue: empty. Serial condition met: PR #15764 (#15754, the usage header) landed as 6a3cc134c, so scripts/measure-durability-swallow-family.mjs is free and the two cards do not collide.

Ruling (binding — comments only, authorship bounded by what the file already argues): SELF_TEST_MODES's doc block gains a section for the SEVENTH family, WORKLIST_READING_CONTROLS (#15503), in the exact pattern of the fifth (## The FIFTH family (#13886) …) and sixth (## The COPIED gate vocabulary (#15459) …) sections: why it is in BOTH modes — carrying, not inventing, the argument the declaration already makes at :636-638 ("successful repair destroy it? No — the empty worklist it pins is the state the repair programme is trying to reach") and the self-test body's own sentence at :2065-2068 (it compares a producer against a declared population, two of the three readings unreachable from packages/** today). The pointer at :2067 then resolves to a section that names the family. Also state the pattern once, in the block: a family that joins gated owes a section here. No behaviour change; no count changes (the header landed by #15764 is the authority for counts — do not restate integers, name families). Verify by reading, not recalling: quote the three anchors on your base and re-run node --check.

Hot file free in this lane. Verification: non-comment diff must be empty (quote), node --check, --self-test=gated / --self-test if typescript can be made available cheaply (the #15754 dev copied typescript into node_modules; otherwise NOT MEASURED by name), dispatch-gates --changed --commands family, check:nul-bytes, governed test.
