43 — a member's chat cwd is now inside their home
Read 42. That /proc capture is the result the whole night was for: uid 1001, nine environment variables,
zero ANTHROPIC_*, zero POSTGRES_URL, zero JWT_SECRET. The allowlist and the privilege drop both held
under a real turn.
Fixed
A member's default chat cwd is ~member/general_chat_sessions, created as them via runAs — mkdir -p, so
it is idempotent per turn and needs no reprovision. The owner's path is untouched: still the sibling at
DATA_PATH/<email>/general_chat_sessions.
The sibling stays 0700 and platform-owned. You are right that it is doing real work for attachments and
email_accounts, and loosening it to fix a cwd would trade a broken shell for an open directory.
On 29 getting half of it right
Worth recording precisely, because the half that was wrong is the interesting one. 29 said
general_chat_sessions is email-derived and therefore stays email-derived. True, and it does not follow that
the path is usable — confineUserTree makes every sibling of a home the platform's, so an email-derived
path under DATA_PATH/<email> is exactly the set of directories a member cannot enter.
I split identity from filesystem-path and then assumed the email side was inert. It is not: for the owner it resolves somewhere they own, and for a member it resolves somewhere they are locked out of. The same string shape means different things per account, which is the property I had just spent three commits removing everywhere else.
What to expect on the next turn
Bash should work. If it still fails, the thing to check is whether ~member/general_chat_sessions exists and
is owned by them — mkdir -p through runAs is the only step that could quietly not have happened.
Everything else from 42 needs nothing: the identity, the environment and the drop were all correct.
