Write-identity lock 1 is absent in multi-repo project threads: the session starts in the parent folder, never loads objectstack's .claude/settings.json deny list, and 26 MCP writes on 2026-10-23 landed as the maintainer's personal account #25583
Description
Filing gate: ① tooling defect with a named landing point, measured in a live session.
Reader: domain:skills seat; the next PR that touches the project-thread session start (the #25380 hook family) or the write-identity locks.
Dedupe (open AND closed): "project thread settings deny MCP write identity" → 3 related hits, all closed and none covering this: #18205 (lock 1 inert because settings load from the clone-time checkout), #25380 (multi-repo working directory hides .claude/skills), #25457 (card threads write only through the relay — a rule in text, not a lock).
reach: measured 2026-10-24 in project thread session session_018fnREjMeK9XQeHDwkJXKMW (the Objectstack project, repos objectstack + objectui).
What happens
A Claude Code project thread with two repositories starts with its working directory at the parent folder (/home/claude), not inside /home/claude/objectstack. The settings that session loads are the launcher's (/home/claude/.claude/launcher-settings.json, whose permissions is {"allow": ["Skill"]}) — objectstack's .claude/settings.json, which denies mcp__github__issue_write, mcp__github__create_pull_request, mcp__github__add_issue_comment and 14 other MCP content writes (lock 1, #18068), is never read. The MCP write tools are offered to the session, and a write through them is authored as the account that connected GitHub — the maintainer's own login.
What it cost, 2026-10-23
26 writes landed under the maintainer's personal account, every one with performed_via_github_app: claude:

The 13 open, unclaimed cards among them are being re-filed through the relay and closed as duplicates; the rest are claimed, closed or merged and stay as they are.
Expected
A project-thread session refuses the same MCP content writes a session started inside the repo refuses, so the relay is the only write path whichever folder the session starts in.
Where the fix can land
- The project-thread session start (the hook family pm-dispatch: a SessionStart hook prints the lane's seat-post stub and the SKILL.md pointer, because a multi-repo project's working directory does not surface the repo's .claude/skills (maintainer's word 2026-10-23) #25380 added) installs the deny roster where the parent-folder session reads it, or refuses to start writes until it is present;
scripts/pm/check-settings-deny-roster.mjsalready holds the roster to copy from. - Until then, every dispatch order and coordinator instruction already carries the relay-only line (pm-dispatch: card threads write to GitHub only through the relay (
pr_createand the other ops), never GitHub MCP; the dispatch order carries that line verbatim; review flags a PR not authored by the fleet bot (maintainer's word 2026-10-23) #25457); this card is the mechanical half that text cannot enforce.

Maintainer-action: give the Objectstack project a cloud environment whose setup script writes the deny roster of objectstack .claude/settings.json (permissions.deny, 17 entries) into ~/.claude/settings.json — done when, in a new multi-repo project-thread session, node scripts/pm/check-settings-deny-roster.mjs --settings ~/.claude/settings.json exits 0 and the GitHub MCP content-write tools are refused

pm:queue+priority:p1(written 2026-10-24T03:52Z) but has no triage audit comment on its thread, so byexecution-duties.md〈候选与批次〉 it is not a dispatch candidate — a label set without its comment is a half state.

No. The GitHub MCP content-write tools that file denies are offered to this session, and the repo's.claude/agents/os-dev.mdagent type is not registered (this seat dispatched its devs as general-purpose agents told to read the file).SessionStarthook run?
