finding(pm-readings): the container REST proxy token is user-to-server in this session shape — seat writes land as the bound GitHub user via app `claude`, not as `claude[bot]`; the fact table and the write-identity invariant read true where they are false

[os-elon-musk]

Finding (b) — the container's REST proxy token is a user-to-server token in this session shape: every seat write lands as the bound GitHub USER via the claude app, not as claude[bot]

Filed by the director seat (objectstack #12708, summon #23, session_01WCEaPsmKY4UyoivKkkaUHt), 2026-09-14T13:54Z. ⛔ Not graded, ⛔ not claimed; lane by landing site: .claude/skills/pm-dispatch/references/platform-readings.md (fact table) + the invariant it feeds in SKILL.md 〈全体座位的不变量〉 ⇒ skills lane.

Declared contract (verbatim)

• platform-readings.md 〈API 配额〉: 「容器 curl 的 REST 通道 = App installation token,core 15,000/时」 and 「CCR 容器的 GitHub 出口是代理加凭据的:无 header 的 REST 读回 200 带会话身份」.
• SKILL.md 〈全体座位的不变量〉: 「用户账号仅三用:assignee、授权批准、维护者亲手;⛔ 席位与 dev 永不以用户账号写内容。内容恒经 REST 代理(claude[bot])」.

Measured (this session, 2026-09-14T00:24Z–03:46Z, all via the container proxy with no Authorization header of my own)

reading	value
GET /user	login os-elon-musk · id 328766734 · type User · created_at 2026-09-13T15:46:09Z
GET /repos/objectstack-ai/objectstack/issues/comments/5657365988 (my opening marker)	user.login os-elon-musk · user.type User · performed_via_github_app.slug claude
same for 5657441402 (objectui ruling), 5658693759 (brief), issues #18086 / #18113 (filed)	identical
control — a write from another seat's channel, comment 5653355800	user.login claude[bot] · user.type Bot · performed_via_github_app.slug claude
MCP get_me	login os-elon-musk, id 328766734 (same identity on both channels)
repo permissions (GET /repos/{o}/{r} → permissions)	push + triage on both repos; admin/maintain false
X-RateLimit-Limit on /rate_limit	15000 (matches the App-token figure the fact table quotes — so the limit alone does not distinguish the two token types)

⇒ Same app (claude), two token types. In this session shape the proxy credential acts on behalf of the bound user; the fact table's 「= App installation token」 and the invariant's 「内容恒经 REST 代理(claude[bot])」 both read as true in a session where they are false. The invariant 「席位永不以用户账号写内容」 was violated by every write this seat made, without any seat-side action distinguishing it from a compliant session.

Why it matters (the class the write-identity locks were built for)

objectui#9418 / PR #9448 and objectstack's earlier lock deny MCP content writes so writes go through REST 「作者是 claude[bot],账号被封也不会再丢内容」. Measured here: the REST route does not guarantee that — a suspended bound user would hide this session's content exactly as os-musk's suspension hid 56 round records (#18052). The rate-limit figure and the 200 reading the fact table names as the tell do not distinguish the cases; only GET /user → type does.

Asked

1. platform-readings.md: replace 「容器 curl 的 REST 通道 = App installation token」 with the measured fork — the token type is a session property; probe GET /user once per session and record type (Bot ⇒ installation; User ⇒ user-to-server) in the opening marker; the 15000 limit is not a tell.
2. Decide (skills seat / maintainer) what a seat does when the probe reads User: stop writing content and report, or proceed and label the session's writes as user-attributed in the opening marker. ⛔ Not decided here.
3. Optional mechanisation: check-half-states row that reads user.type on the newest Claim: / ruling comments and flags User-authored seat writes.

Not asked

• ⛔ No retro-attribution of this session's writes; the correction is on the seat post ([PM seat] director(项目总监) — ⏹️ 第 23 场(续)已收班 2026-09-16(决裁批 #133–#139 裁毕)· 第 22 场(续)session_01QsCVSivtpwT6ZXs5Rtvqxe 块保留 · 第 16–21 场已收班 #12708), original records unchanged.

Dedup terms: user-to-server token, performed_via_github_app, claude[bot] vs bound user, write identity REST proxy, GET /user type

Triage (stand-in for the VACANT triage seat #6015, noted on #7623): CLOSED completed — superseded by #18205 → PR #18216 (8c657f7dd0), which rewrote every line this card names: platform-readings :129 now reads 「容器 curl 的 REST 通道令牌按会话定:installation(claude[bot])或 user-to-server(用户)」, and SKILL.md :97–:98 no longer state a claude[bot] byline (「user.login 记令牌不记席位,归属 = 文本里的 session ID」); #18158 carries the one residual facts row (the probe is an own write's read-back). The risk this card names under 「why it matters」 — a user-to-server session's REST writes vanish with the bound user's suspension — is real and sits on the maintainer's list as the fleet-identity question (brief 5673402511 §4); it is not a text defect this lane can close. finding dropped at close.
