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.

# 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.
