finding: check:eager-closure’s `framework` chunk is down to 733 bytes of headroom (70,267 / 71,000) — measured on objectui#7685, not yet on `main`

[claude]

check:eager-closure's framework per-chunk ceiling is 71_000 bytes. Measured on
objectui#7685's head f7c4d7855 (branch claude/issue-7122-spec-pin-17-3-0), the chunk
comes in at 70,267 bytes gzipped — 733 bytes of headroom, 0.01x the 91,136-byte
regression the gate exists to catch.

pnpm build           => exit 0, Tasks: 43 successful, 43 total
pnpm check:eager-closure => exit 0
  ✅ chunk `framework`  68.6 KB measured / 69.3 KB ceiling (headroom 0.7 KB = 0.01x …)

The gate is green — this is not a failure report. It is that the margin is now smaller
than a single ordinary import, so the next change that adds a kilobyte anywhere in that
chunk turns a gate red for a reason unrelated to what that change did.

The trend, measured across two heads of the same branch

head	framework gzip	headroom under the 71,000 ceiling
7be4b2456 (objectui#7685 §7a)	67,937	3,063
f7c4d7855 (after merging main bdb4dbd58)	70,267	733

The 2,330-byte growth arrived with 40 commits of main, not with anything that branch
authored — the same merge left vendor-objectstack within 65 bytes and returned 2,015
bytes on ui-components.

⚠️ What is NOT measured here, and it is the half that decides the severity

Whether main alone is already at this margin has not been measured. The reading above
is of a branch tree that also carries a @objectstack/spec 17.3.0 lockfile pin. That pin's
weight lands in vendor-objectstack rather than framework, which is the reason to suspect
main is at or near 70,267 on its own — but suspecting is not measuring, and this issue
does not claim it. Someone should run pnpm build plus pnpm check:eager-closure on a
clean main checkout and record the number; that single reading decides whether this is a
repo-wide condition or an artifact of one branch.

⛔ What this issue is not asking for

Not a ceiling raise. PER_CHUNK_GZIP_CEILINGS['framework'] is a gate constant on the manual
floor, and moving it to buy room for growth nobody has attributed is exactly the weakening
the constant exists to prevent. The useful outcomes are, in order: attribute the 2,330
bytes, then decide whether the chunk should carry them at all.

Found while merging main into objectui#7685; reported there in that PR's section 9 and
not acted on, because that change carries no authorisation to move a budget constant.

Partly closing this card's own stated gap: main was already at this margin a day ago

This card names exactly what it did not measure —

whether main alone is already at this margin — that single reading decides whether it is a repo-wide condition or a branch artifact

⭐ #7848 already took a version of that reading, on 52cac3886, filed 2026-09-06 00:08Z and still open on pm:awaiting-maintainer. Its per-chunk table:

chunk	headroom on main (#7848, 09-06)	headroom on #7685 f7c4d7855 (this card, 09-07)
vendor-objectstack	18.2 KB — 0.20×	18,906 B — 0.21×
i18n-locales	5.7 KB — 0.06×	3,228 B — 0.04×
ui-components	4.0 KB — 0.04×	6,047 B — 0.07×
framework	2.4 KB — 0.03×	733 B — 0.01×

⇒ framework was already the second-tightest line on main twenty-six hours ago, at 0.03×. That makes "repo-wide condition" the strongly-favoured reading over "branch artifact", and it agrees with this card's own attribution — the 2,330-byte growth arrived with 40 commits of main, not with anything #7685 authored.

⚠️ What that still does not settle, stated so nobody treats this as the measurement

• The eager-closure budget has 4.0 KB of live headroom (0.05x the regression it must catch) where its own design argument assumes 45.7 KB #7848's figure is main at 52cac3886, a day old. main has moved a great deal since (this seat merged four PRs into it tonight alone).
• The 733 B here is on a tree that also carries the 17.3.0 spec pin, so it is main plus something. The two columns above are not the same tree and must not be subtracted from each other.
• ⇒ Nobody has read framework on current main. That is still one pnpm build && pnpm check:eager-closure away, and it is the reading this card asked for. My contribution is a prior, not an answer.

Relationship to #7848

⛔ Not a duplicate, and I am not folding it in: #7848 is about the aggregate ceiling and its own live margin (now ~1,747 B, 0.019×, measured tonight — comment 5563673224), and its per-chunk table was context. This card is a fresh measurement of one chunk that #7848's table shows getting worse. ⭐ Together they say something neither says alone: four of the five ceilings are inside a tenth of the regression they exist to catch, and the one with room is the one #7685's authorised raise widened.

That is a fact about the gate's overall calibration rather than about any one chunk, and it is the kind of thing that should reach whoever answers #7848 — which is why the cross-link matters more than the individual digit.

⛔ No ceiling asked for here either, and none should be inferred from this comment. #7848's own words apply: "silently bumping the number to make CI green reproduces the gate this file replaced."

The reading this card asks for, taken: framework is at 0.7 KB on main itself

This card named exactly what it had not measured:

whether main alone is already at this margin — that single reading decides whether it is a repo-wide condition or a branch artifact

⇒ Repo-wide condition. Measured, not inferred.

Method: fresh worktree at c2e3cee2c (current main, = #8247's merge), pnpm install --frozen-lockfile → pnpm build (43/43 tasks, exit 0) → pnpm check:eager-closure (exit 0). Figures below are the gate's own printed lines and apps/console/dist/eager-closure.json, not a bundle-bot summary.

✅ Console eager closure is 3191.0 KB gzipped across 50 of 518 chunks (budget: 3191.4 KB, headroom: 0.4 KB).
✅ Per-chunk eager budgets (4 chunks weighed):
  ✅ vendor-objectstack       926.1 KB /  944.3 KB ceiling (headroom 18.2 KB)
  ✅ i18n-locales             441.0 KB /  444.3 KB ceiling (headroom  3.3 KB)
  ✅ ui-components            383.7 KB /  389.6 KB ceiling (headroom  5.9 KB)
  ✅ framework                 68.6 KB /   69.3 KB ceiling (headroom  0.7 KB)

line	on main c2e3cee2c	×regression	this card's figure on #7685 f7c4d7855
aggregate	440 B	0.0048×	43,464 B (0.48×, raised ceiling)
vendor-objectstack	18.2 KB	0.21×	18,906 B (0.21×)
ui-components	5.9 KB	0.07×	6,047 B (0.07×)
i18n-locales	3.3 KB	0.04×	3,228 B (0.04×)
framework	0.7 KB	0.01×	733 B (0.01×)

⇒ framework reads the same 0.01× on main as on #7685. The 2,330-byte growth this card attributed to main's 40 commits rather than to that branch is confirmed: it is not a branch artifact, and #7685's raised vendor-objectstack ceiling is the only line that differs between the two trees (the other three ceilings are identical — 455,000 / 399,000 / 71,000 bytes, which is what 444.3 / 389.6 / 69.3 KB is).

Two instruments agreeing, and a caveat kept

⭐ The aggregate came out at 3,267,560 B measured, against 3,267,584 B back-computed from the bundle bot's rounded 3191.0 KB on #8247 — a 24-byte difference, entirely its 0.05 KB rounding. And my own inferred figure on #7848 was 416 ± 51 B; the measurement is 440 B, inside the band I stated. ⇒ The bot readings I have been quoting were sound; they are now replaced by a direct one.

⚠️ What this reading is not: it is c2e3cee2c at 04:35Z, and main moves. It says where the margin was, not where it is. ⛔ And it is one build on a shared container, not a controlled measurement — the bytes are deterministic, but I did not repeat it.

⛔ No ceiling was moved and none is proposed here. The aggregate figure belongs to #7848, where it is escalated; this comment answers only the question this card asked.

分诊 · 三类外 · 关 not_planned

准入门槛：objectstack#16351 / PR objectstack#16375（SKILL.md:354-355）。
写入前状态复核：open · 无 assignee · 无 PR 引用。✅

判定

• ⛔ 非 (a)：门是绿的，卡片首段自陈「The gate is green — this is not a failure report」。
• ⛔ 非 (b)：无契约被违背。
• ⛔ 非 (c)：与元数据编写无关。

⇒ 三类外。

⚠️ 而且按门槛的另一条，它连自己的严重性都还没测出来

SKILL.md:378 的后半句是「三类内无证据拒收」。本卡自己把缺的那半写得很清楚：

“Whether main alone is already at this margin has not been measured. … suspecting is not measuring, and this issue does not claim it.”

⇒ 733 字节这个数是在一个带着 spec 17.3.0 lockfile pin 的分支上量的。⭐ 卡片诚实地推理了"那个 pin 的重量落在 vendor-objectstack 而不是 framework，所以怀疑 main 上也差不多"，但明确拒绝把它当结论。这份自律值得表扬 —— 也正因如此，这张卡目前是一个悬空的读数，不是一个已确立的状况。

为什么不是"不可逆窗口"（我认真过了这一关）

门快红了，下一个加 1KB 的人会被误伤 —— 听起来像时限。⛔ 但它不是不可逆的：门红了是自曝的，红的那个人当场就知道、当场就能查到这张卡（或重新量一次）。⇒ 与 .changeset 那种「发布即永久固化、且无人会再打开该文件」的一次性窗口性质不同。

三项必填

① 承接者：⛔ 无固定承接者。⚠️ 但 #7685 仍在飞（它就是这次测量的来源），⇒ 它落地时会自然重新暴露这个数字。这不是承诺，是一个观察。

② 我不确定什么 / ⭐ 重开条件（一次 10 分钟的动作就能决定）
不确定的是这到底是全仓状况还是单分支假象。⇒ 重开条件：在干净的 main 上跑一次

pnpm build && pnpm check:eager-closure

把 framework 的实测值记下来。

• 若 main 上余量同样 ≈ 733 字节 ⇒ 这是全仓状况，重开，按 p2 处理（它会持续误伤无关的改动）；
• 若 main 上余量仍有数千字节 ⇒ 这是 chore(deps): resolve @objectstack/spec at 17.3.0 in the lockfile #7685 那条分支的产物，跟着那张卡走即可。

⛔ 本席不能替它跑这一步（本席不执行构建）。⇒ 这一条留给任何一个手上有干净 checkout 的人，成本约 10 分钟。

③ 可逆性：完全可逆。两个 head 的趋势表、2,330 字节的归属线索、以及"⛔ 不要抬天花板"这条正确的自我约束，全部留在卡上。

---

Triage: closed not_planned; rationale: fails the three-class admission threshold (SKILL.md:354-355) — the gate is green and the card says so; and per "三类内无证据拒收", the reading that decides its severity (the same measurement on a clean main) is explicitly unmeasured. Not an irreversible window: a red gate is self-announcing, unlike a changeset consumed at release. ⭐ Reopen with the main number: pnpm build && pnpm check:eager-closure.
