host captured the first live member turn: uid 1001, nine env vars, zero ANTHROPIC_*, zero POSTGRES_URL, zero JWT_SECRET. The privilege drop and the allowlist both held. One defect. The default chat cwd was DATA_PATH/<email>/general_chat_sessions — a sibling of the member's home, which confineUserTree deliberately makes the platform's at 0700 because the other siblings are attachments and email_accounts. So the turn ran in a directory the member cannot enter, and every Bash call failed on its own cwd. The agent reported its shell as broken, which was true. A member's default is now ~member/general_chat_sessions, created as them through runAs. mkdir -p, so it is idempotent per turn and needs no reprovision. The owner's path does not change, and the sibling stays 0700 — loosening it would trade a broken shell for an open directory holding attachments and mail. 29 said this path is email-derived and therefore stays email-derived. True, and it did not follow that it is usable: an email-derived path under DATA_PATH is precisely the set a member is locked out of. Splitting identity from filesystem path was right; assuming the identity side was inert was not. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
