resolving a member's task symlink needs their identity too
One layer below yesterday's fix, and it looked identical on screen: the job was
found, then declared to have written nothing.
`loadBackgroundTask` resolved the located path with `realpathSync`, as the
platform. Resolving a link needs `x` on every directory above it, and
`/tmp/claude-<uid>` is `drwx------` — so it threw EACCES on an INTACT link, and
the catch below it reported that as a dangling symlink and returned null. The
tray polls, gets `{kind:'pending'}`, and shows "Nothing written yet" forever.
The lookup fix could not have exposed this: it made the file findable, which is
precisely what let execution reach the line that then threw it away.
`realpath -e` rather than `readlink -f`, because `-e` requires every component to
exist — that keeps a genuinely dangling link reporting as one instead of
resolving to a path that is not there. Verified against symlink, plain file,
dangling link and missing path: `realpath -e` and `realpathSync` agree on all
four, so the owner path is unchanged.
Audited the rest of claude-sessions.ts for the same shape. Every remaining
mention of `statSync`/`readdirSync`/`Bun.Glob` in that file is a comment
explaining why it is NOT used.
Live coverage extended: the member resolves their own link, the platform gets
null. Skips without OFFICER_TEST_MEMBER.
tsgo clean, frontend builds, 865 pass / 7 fail unchanged, 7 skips.

a member's background job can be read and stopped
A member started `bun dev`, watched it run, and got no logs at all — then
`{"stopped":false,"reason":"no such task"}` from the Stop button. Two symptoms,
one cause, and it is the same one `read-as-user.ts` was written for.
`findTaskOutput` globbed `/tmp/claude-*/…` as the platform's own uid.
`/tmp/claude-<uid>` is `drwx------` (checked, not assumed), so for a member that
directory cannot even be traversed. A glob that cannot traverse does not throw —
it returns an empty iterator. Both callers read that as "no such task": the log
view showed "Nothing written yet" forever, and Stop refused an id that was
perfectly real.
Every other filesystem access in that module already goes through the as-user
helpers. This one path never did, and it was invisible for as long as only the
owner used chat.
So the lookup moves into `findPathAs`, and Stop runs as the member too — both
halves of it. `fuser` reads `/proc/<pid>/fd`, which only the process's own user
and root may open, so as the platform it would have found no pids and reported
the job already stopped; the kill after it would have been cross-user EPERM,
swallowed by a catch. Neither would have said anything.
── The exit code is ignored, and that is the point ──
The first version of this fix located the file and threw it away. `find` exits 1
when it cannot descend into something, and searching `/tmp` from ANY identity
hits another account's `drwx------` — it prints the match on stdout first, then
returns 1. Treating that as failure reproduced the original bug through a new
mechanism. Caught by testing the owner path against a real task file rather than
assuming the refactor was behaviour-preserving; a missing root still exits 1 with
empty stdout, so absence still reads as absence.
Owner and member now take the same `find`, deliberately: one set of matching
semantics, rather than a glob for us and a find for them, which is how a bug ends
up reproducing on one account and not the other.
Verified on the owner path here against a live task file. The member path is
covered by `read-as-user.live.test.ts` — same opt-in shape as
`spawn-as-member.live.test.ts`, asserting the two identities DISAGREE, which a
world-readable tree would not satisfy. It cannot run on a machine with one
account, so it skips here and needs OFFICER_TEST_MEMBER on the host.
tsgo clean, frontend builds, 865 pass / 7 fail unchanged, 3 new skips.

reach a member's transcripts by listing them, not just by reading them
yesterday's fix routed transcript CONTENT through the member's identity and
stopped there, on the strength of a comment in ChatIdentity saying enumeration
never needed it — "their directories are 775 and the platform holds an ACL
entry, so readdirSync and statSync have always worked".
there are no 775 directories on this path. claude creates ~/.claude/projects/
and every project group at mode 700, and a 700 directory clamps the ACL mask to
--- exactly as a 600 file does:
user:officer:rwx #effective:---
mask::---
measured against a real member home:
existsSync(projects) -> true (stat only needs traverse on .claude)
readdirSync(projects) -> EACCES
existsSync(projects/<slug>) -> false
statSync(<transcript>) -> EACCES
existsSync answering false rather than throwing is why this was invisible: every
caller read it as "no such session". one root cause, three reported symptoms —
an empty conversation list, no title on a new chat, and a /chat/<id> deep link
that never restored the conversation. a fourth nobody had reported yet: delete
removed nothing and still answered ok, because unlink needs w+x on the group
directory too.
so enumeration goes through the same door as content, as ONE call rather than a
spawn per entry: listTranscriptsAs runs a single `find` as the member and
returns every transcript with its mtime, which readdir+stat could not do without
dozens of setpriv forks per request and a matching pile of auth.log lines. the
owner keeps a fork-free path — that process already IS the owner. removeAs does
the same for unlink, and readTailAs no longer stats a file it cannot stat.
summarizeTranscript now takes the mtime it is given instead of stat'ing again,
which is both the fix and one less syscall per file.
verified against jg@pertento.ai on this machine: 6 conversations listed with
titles from their first prompts, and a deep link by id alone loads 71 messages.
owner path re-checked and unchanged.

read a member's transcripts as the member
a provisioned member could chat normally and had no conversation list. every
refresh came back empty, so nothing could be resumed, and a new chat never
became a saved one.
nothing was wrong with the logic. the turn runs as them, writes its transcript
into their home, and the platform looks in exactly the right place — it just
cannot read what it finds.
confineUserTree grants the service user a named acl entry on every member home,
with d: defaults so anything created later inherits it. that entry is real and
getfacl shows it. it does not survive a file created at mode 600, because posix
derives the acl mask from the group bits of the creation mode:
user:officer:rwx #effective:---
mask::---
claude writes every transcript at exactly that mode — .claude and projects/ are
775, every *.jsonl is 600. so readdir and stat worked, every read raised eacces,
and summarizeTranscript catches eacces and returns null. the sessions did not
fail, they vanished.
no acl can fix this. the creation mode ands the mask down, so d: defaults cannot
raise it, and the only way up is through `other`, which is every account on the
box. a 600 file has two readers: its owner, and root.
so read as the owner of the file, through the same runAsArgv the terminal and
the agent already use. spawnSync keeps it synchronous, which is what lets it
drop into a 914-line synchronous parser reached from five modules instead of
rippling await through all of it.
the privileged surface turned out to be seven call sites, not the file: stat
needs traverse and readdir needs read, and the 775 directories give both. only
content needed identity.
also fixes a 500. parseClaudeTranscript read the file uncaught after an
existsSync that passes, so deep-linking /chat/<id> as a member threw rather than
404ing. it returns null now, like the list path always did.
verified against a throwaway linux account provisioned the same way a member is
— 700 home, named acl, transcript written as them at 600. before: 0 sessions and
loadClaudeSession null. after: the session, its title, its messages, and a
rename that leaves the file owned by the member at 600.
