[finding] seat-side read-back judge (post-stamped classifyReadBack / fleet-write) answers NOT STORED on a correctly stored body while the proxy-side #N read expansion is active, and its remedy sends the seat to re-send the expanded text

Filing gate ①, finding class (b) — a declared contract the tool cannot keep while a measured platform behaviour is active — tooling. Escalated to this seat by the at-tier contract review 6283172819 on PR #24744 (boundary flag ③-2), from the #24729 developer's carrier-none note. Filed by the domain:skills seat 1 (os-justin, session session_01HEdP5tPhqQfzwRmKDxwn85). ⛔ Not a claim. Filed bare: lane, grade and type are triage's (cross-repo-coordination.md:37); the landing is scripts/pm/**, which the skills lane holds.

Reader who acts: the domain:skills lane seat — one tooling PR on scripts/pm/post-stamped.mjs (classifyReadBack, line 2617 on origin/main 4a2ca57e7) and, only if the locator needs it, scripts/pm/fleet-write/dispatch.mjs (READ_BACK_LOCATORS), with a self-test fixture. ⛔ No new gate (「新增门禁默认否」): this changes what a judge counts as "landed", it adds no check to any PR.

reach: 具名真实生产者 — the proxy-side rewrite on the seat's REST read path in a CCR container, which the fact table records since PR #24744 (platform-readings.md 配额段: 「代理侧 REST 读的 body 间歇把裸 #N 展开成 owner/repo#N」). Measured twice, by two seats: comment 6279597228 (sent with 35 bare #N, read back by the relay identical at 4,673 bytes) read at 03:39:09Z on 2026-10-20 as 5,667 chars / 5,751 bytes with 40 objectstack-ai/objectstack#N (PR #24744 body, 〈Readings〉); the director post #12708 read with 117 expansions against its raw 14,657 bytes (ledger block 6281946060 on #12708). The expansion is intermittent (6282030487): 0 expansions on the same path minutes earlier and later. The judge's wrong verdict is read in the code below and has NOT been reproduced end to end: every seat-side read-back of this shift (about fifteen relay writes) came back identical.

The contract, quoted (`scripts/pm/post-stamped.mjs` header, `origin/main` `4a2ca57e7`)

DID EVERY BYTE THIS ACT SENT REACH THE PLATFORM? … All FIVE benign classes keep the sent body's CONTENT whole … mutated is the only class that answers no, and since #18693 it is also the only class that CAN: … so a difference this fleet has measured never reaches the word mutated in either act.

and scripts/pm/fleet-write/dispatch.mjs header (the run's success is the executor's, not the write's):

only the SEAT, which holds the bytes it meant, can. So after a success run sendFleetWrite reads back every action that carried a body … and judges the stored bytes against the bytes sent with post-stamped's own classifyReadBack / sentBodyLanded.

The seat-side read-back therefore runs on exactly the read path the fact table now says rewrites references. A difference this fleet has measured (the expansion) does reach the word mutated.

What the code does with an expanded read-back (by construction)

classifyReadBack({ sent, stored }) admits identical, trailing-newline-stripped, footer-appended, footer-re-anchored, footer-blank-collapsed; everything else is mutated. A body stored byte-for-byte as sent, carrying k bare own-repo references, reads back +26·k bytes with objectstack-ai/objectstack#N in place of #N (the measured shape): none of the five arms matches ⇒ mutated ⇒ EXIT_NOT_STORED (exit 4) on post-stamped, and verdict not-stored on the fleet-write row.
notStoredText (dispatch.mjs, the printed remedy) then says: 「The write HAPPENED. Go READ what is stored and send a body that can land. ⛔ Do not re-run blind」. A seat that follows it reads the expanded body and sends it back — and that second write stores the expansion for real: the exact trap [finding] platform-readings: the container REST read path returns issue and comment bodies with every bare #N expanded to owner/repo#N, so a body rewrite built on a REST read writes the expansion into the stored text #24729 records, reached through the tool's own door.
Where the locator finds a comment by its sent bytes, an expanded listing finds nothing ⇒ unverified, exit 6 (「only read, ⛔ never retry」 per rest-channel.md:18), a landed write reported as unconfirmed.

The run's success and the executor's echo are unaffected (the relay reads back on the runner, outside the proxy); only the seat-side judge is.

Dedupe: REST enumeration of this repository, GET /repos/objectstack-ai/objectstack/issues?state=all&since=2026-10-17T00:00:00Z&per_page=100 (8 pages, 796 items, pull requests skipped), title+body matched against /classifyReadBack|read-?back.{0,80}(expan|owner\/repo#|裸)|回读.{0,60}(展开|owner\/repo#)|not-stored|unverified.{0,40}expan/i → 0 hits. Nearest: #24729 (the read-side fact; its remedy is a seat habit and reaches no script), the closed write-side read-back findings #18693, #19048, #19312 (the footer arms — the shape this one extends). No open card.

What done looks like

Before a read-back is classified mutated, the judge collapses the own-repository prefix in stored — every objectstack-ai/<this repo>#N back to #N, nothing else — and classifies again; a match after the collapse is a declared benign class of its own (a name such as reference-expanded-on-read), exit 0, with one stderr line naming the count, so the reading stays visible and body_landed stays true. The same collapse applies to the locator's bytes-based lookup. The length-proof arm of the ruled remedy (fetched length − 26·k = sent length) may serve as the check that the collapse restored the bytes exactly.
⛔ Not widened: no change to the footer arms, no tolerance band, no gate, no label; a body whose bytes differ after the collapse is still mutated.
A self-test fixture pins it: sent with bare references, stored as the measured expansion, verdict landed; and a control where the stored body differs by one byte besides the expansion, verdict mutated.

Premises, each with its re-check

The five classes and the mutated fall-through: grep -nE "identical|trailing-newline-stripped|footer-appended|footer-re-anchored|footer-blank-collapsed|mutated" scripts/pm/post-stamped.mjs around line 2617 (classifyReadBack).
The seat-side judge runs in the container on the proxied read path: scripts/pm/fleet-write/dispatch.mjs header 「only the SEAT … can」 and sendFleetWrite's read-back.
The expansion is a recorded fact on main once PR docs(pm-skill): record the intermittent REST-read reference expansion in platform-readings #24744 merges: grep -n '间歇把裸' .claude/skills/pm-dispatch/references/platform-readings.md → one line under 〈API 配额〉.
The printed remedy text: grep -n 'Go READ what is stored' scripts/pm/fleet-write/dispatch.mjs → notStoredText.

Acceptance

node scripts/pm/post-stamped.mjs --self-test and the fleet-write self-tests pass with the new fixture and its control; pnpm check:pm-write-pace unaffected.
A read-back whose only difference from the sent bytes is the own-repo reference expansion exits 0 with the new class named on stderr; one differing byte besides it still exits 4.
The PR body names [finding] platform-readings: the container REST read path returns issue and comment bodies with every bare #N expanded to owner/repo#N, so a body rewrite built on a REST read writes the expansion into the stored text #24729 / PR docs(pm-skill): record the intermittent REST-read reference expansion in platform-readings #24744 as the fact's record and review 6283172819 as the escalation; Fixes closes this card.

[finding] post-stamped.mjs's header declares the issue-body footer cell UNMEASURED while platform-readings carries the measurement — every seat-post refresh prints a MUTATED warning #18693, finding(scripts/pm): post-stamped.mjs exits 4 "NOT STORED" when the platform's footer re-anchor COLLAPSES a blank line — a case its own refusal text says cannot happen ("takes nothing away either way") #19048, finding(scripts/pm): post-stamped exits 4 NOT-STORED when the platform merely RELOCATES the body's own footer #19312 (closed) — the footer arms of the same classifier.

若实测表明真正的生产者在别处,直接按生产者侧修,落点与理由写进报告和 PR 正文。

一、裁决(不可重裁)

卡正文〈What done looks like〉逐字:「Before a read-back is classified mutated, the judge collapses the own-repository prefix in stored — every objectstack-ai/<this repo>#N back to #N, nothing else — and classifies again; a match after the collapse is a declared benign class of its own (a name such as reference-expanded-on-read), exit 0, with one stderr line naming the count, so the reading stays visible and body_landed stays true. The same collapse applies to the locator's bytes-based lookup. The length-proof arm of the ruled remedy (fetched length − 26·k = sent length) may serve as the check that the collapse restored the bytes exactly.」「⛔ Not widened: no change to the footer arms, no tolerance band, no gate, no label; a body whose bytes differ after the collapse is still mutated.」「A self-test fixture pins it: sent with bare references, stored as the measured expansion, verdict landed; and a control where the stored body differs by one byte besides the expansion, verdict mutated.」
「The same collapse applies to the locator's bytes-based lookup」那半句落在 fleet-write/dispatch.mjs 的 READ_BACK_LOCATORS(按内容找评论),属兄弟卡文件面 ⇒ 本 PR ⛔ 不做,在报告 deviations 与 PR 正文写明「locator 半句待 fleet-write: a relay stroke of up to 20 content-creating writes runs at the 3 s gap — write-pace rule ⑤ (batch gap 30 s) never applies on the relay path, so one stroke is a burst #24755 落地后另起」;判定器半句(fleet-write 的 dispatch.mjs:700 调的就是 post-stamped 的 classifyReadBack,1713 行自测钉着「judge is post-stamped's, imported」)由本 PR 覆盖。
事实出处:platform-readings.md:246(PR docs(pm-skill): record the intermittent REST-read reference expansion in platform-readings #24744 落地)「代理侧 REST 读的 body 间歇把裸 #N 展开成 owner/repo#N:重写前折回本仓前缀或核长等原长。」;复审 6283172819 旁注 ③-2 是升级来源。分诊:p2 tooling(标签 05:52Z,无评论)。⛔ 无新门禁、无新标签。

二、PM 机制假设(须实测,鼓励证伪)

classifyReadBack({ sent, stored } = {}) 的签名被自测钉住(第 4459 行的正则 ^function classifyReadBack\(\{ sent, stored \} = \{\}\));新增的「本仓」信息若作为第三个解构字段会破这个钉 —— 两条路:改钉(同一 PR 内,写明)或不改签名、由调用方传的 stored 之外的途径(例如模块级常量/--repo 解析出的仓名由一个薄包装函数先折回再调判定器)。你选并写明。
折回算法的精确形态:实测展开只改「裸 #N」且紧跟左括号的 3 处未被改写(PR docs(pm-skill): record the intermittent REST-read reference expansion in platform-readings #24744 正文);sent 自己也可能带作者手写的全拼 objectstack-ai/objectstack#N。所以 ⛔ 不能对 stored 全局 replaceAll 后与 sent 比(会把手写全拼也折掉);正确做法是从 sent 出发:对 sent 里每个裸 #N(前一字符非 /、非字母数字),允许 stored 在该位置是 #N 或 objectstack-ai/objectstack#N,其余字节逐字相等 —— 即由 sent 构造一个精确匹配器,计数 k。
新类别要进 sentBodyLanded 的「landed」集合,--json 的 body_mutated 对它为 false、body_landed 为 true;消息表(第 2416 行附近)加一句;stderr 一行点名 k。
现有五类与 footer 两臂(footerReAnchoring)原样;折回只在判 mutated 之前的最后一步做,且折回后还得过同一套类判定(折回后可能等于 identical,也可能是 footer 形 —— 组合形态要定义清楚:折回 + footer-appended 算哪一类?建议:折回后再走一遍既有判定,类名取既有类名并在结果上加 referenceExpanded: k 字段;只有「既有判定全不中」才是 mutated)。你实测后定,并把组合形态写进自测。
--self-test 在本文件内(第 934 行起「Pure core」,t( 断言);pnpm check:pm-post-stamped 跑它;dispatch.mjs 的自测(pnpm check:pm-fleet-write-dispatch)引用 post-stamped 的判定器 —— 你不改 dispatch.mjs,但要跑它的自测确认仍绿。
门禁清单里 check-scripts-symbol-anchors、check-self-test-wired、check:pm-write-pace 等对本文件敏感;新增导出或改签名先跑一遍看它们认什么。

三、PM 建议路线(可选,实测优先)

在 classifyReadBack 判 mutated 之前加一步:用假设 2 的「从 sent 构造匹配器」得到 k;k > 0 且其余字节相等 ⇒ 返回既有判定对折回后 stored 的结果,附 referenceExpanded: k;sentBodyLanded 不变(读既有类名即可)。这样「新类」其实是既有类 + 一个计数字段,消息表只加一行「… with k bare reference(s) expanded on the read path」。若你认为必须单列类名,按卡上 reference-expanded-on-read 命名,并把它加进 landed 集合。
自测:① sent 含 3 个裸 #N,stored 为展开形(其中 1 个紧跟 ( 不展开)⇒ landed、k=2;② 同上但 stored 另差一个字节 ⇒ mutated;③ sent 含手写全拼引用、stored 原样 ⇒ identical、k=0;④ 展开 + 平台 footer 追加的组合;⑤ 反向突变:把折回关掉,①必须变红。
PR 正文:引卡与 platform-readings.md:246;写明 locator 半句的去向;## 维护者速读(草稿)(业务话:写入成功却被判「没存上」的假红,与随之而来的「去读展开后的正文再发」的坑)。
PR 保持 draft;翻 ready 与入队由席位做。

每个方案必须沿四条固定评估轴分析,这是决策分析的核心原则,不是可选项:

实际业务需求 — 它服务的是真实存在的业务场景,
还是投机性能力面?判据要求实测(谁在写这个键、谁在读、
示例应用与真实部署的用法),「读起来像有用」不作数。这条轴会改变结论,不是陪衬。
项目长远合理性 — 哪个方案符合北极星方向与可持续架构(no workarounds、
contract-first),临时补丁式选项要明说长期代价。
防 AI 写代码犯错,尤其是防 AI 写元数据 app 犯错 — 哪个方案让 AI 在结构上更难写错:
契约收紧(严格 schema、publish 时响亮拒绝)优于消费端宽容(?? 回退、静默容错)——
宽容恰是 AI 批量犯错被掩盖的温床;声明即强制,绝不让 AI 声明一个运行时不兑现的能力。
创业阶段不扩散需求 — 创业阶段聚焦原则:创业项目先专注核心能力,能力扩张默认
从紧,无拉动的声明面按 implementation-first 处置,已发布零消费能力不因沉没成本豁免。
过渡也从紧 —— 创业阶段不渐进:废弃别名/拼写与能力退役默认立即退休,无分阶段
窗口、无双拼写宽限;staged 仅凭具名外部用户证据方可荐。新增门禁默认否:门禁是只减
不增的零件,例外只有维护者点名;荐新增门禁须引其点名原话,否则荐「不加」。

基本裁决原则:spec 声明 > 实现 > 文档面;声明而未兑现是实现缺口,补实现或退役,
⛔ 不在消费端收窄;未声明键随实现,文档随之。「声明即强制」只及 spec 与元数据契约、
运行时能力,⛔ 不及 AGENTS.md 这类给 agent 读的约定 —— 那些的读者是 agent,不是门禁。
推荐意见必须基于这四条轴给出理由;四轴冲突时如实呈现权衡,
交维护者拍板。

Per the dispatch, the dispatch.mjs-side remainder waits until #24755 lands and is taken up then (locator 半句待 #24755 落地后另起).",
    "Hypothesis 4 (existing class plus a count field) was not taken. The card's ruled text asks for 「a declared benign class of its own」, and dispatch.mjs's relay row prints only cls, so reusing 'identical' would describe bytes that were not read. Chosen: class reference-expanded-on-read, with the inner class kept as afterCollapse.",
    "Hypothesis 1: no signature change and no pin change. A repo parameter would leave the relay path, the one the expansion lives on, uncovered, because dispatch.mjs passes { sent, stored } only. The prefix is read off the stored body and limited to the GOVERNED_REPOS roster, one per body. Residual, documented in the header: a body whose every bare reference came back naming a sibling roster repository would pass; this is unmeasured, and the exact cure is the caller passing payload.repo.",

Non-governed (scripts/pm/**): the seat's ACCEPT at TIER_DEFAULT is the review of record; readied and armed (pr_ready + automerge_enable) through the relay once CI converged green. The queue merges it; Fixes #24747 closes this card and the seat then removes pm:dispatched.
Carried for the dispatch.mjs remainder (after fleet-write: a relay stroke of up to 20 content-creating writes runs at the 3 s gap — write-pace rule ⑤ (batch gap 30 s) never applies on the relay path, so one stroke is a burst #24755 lands): the relay row prints the class but not the count; notStoredText carries no collapse warning; passing payload.repo would make the prefix exact.

State change: the card closed completed by the PR's Fixes; pm:dispatched removed. The read-back judge on main now collapses the read path's own-repo reference expansion before calling a body mutated; the dispatch.mjs remainder (count on the relay row, collapse warning in notStoredText, payload.repo) is the seat's follow-up after PR #24810.
