pastilhasandClaude Opus 5 a64d5610e6 officer-setup section 5: Postgres, and only Postgres
The original offered five containers. Of those:

  Postgres    the only database Officer has — account, passkeys, settings,
              dashboards, email accounts, the queue. Required.
  Redis       not referenced anywhere in the platform. No import of the client,
              no environment variable, no mention; the only "redis" string in
              src/ is the word "rediscover" in a comment. Dropped. (It is still
              in package.json and comes out in the dependency pass.)
  SearXNG     zero references anywhere. Dropped. If it ever arrives it brings
              its own compose file and its own Redis with it.
  Mailhog     a development convenience, offered separately rather than here.
  Nginx PM    a deployment choice — Caddy, Traefik, nginx or the tailnet — and
              not something a setup script should pick.

Provisioned into $OFFICER_ROOT/dockers/postgres/, the same convention the app
store uses: one directory per service, the compose file in it, relative bind
mounts so the data sits beside the compose file.

Bound to 127.0.0.1, deliberately and with the reason in the compose file itself.
Docker publishes ports by writing iptables rules underneath ufw, so "5432:5432"
is reachable from the internet whatever the firewall reports — the same mechanism
the machine-setup firewall section exists to close. The platform runs on this
machine, so loopback is all it needs.

The password lives in a 0600 .env beside the compose file rather than inside it,
so the compose file can be read or copied without carrying a credential. A second
run reuses it rather than minting a new one, which would leave the container and
the URL disagreeing.

Readiness is waited for rather than assumed: Postgres initialises its data
directory on first start, and db:push against a database that is still starting
fails in a way that reads as a schema problem.

Choosing an existing database checks the URL but does not insist on it — the URL
may be right and the database not yet started, and refusing to continue over that
would be worse than saying so.

Also carries the whitespace fix for the comment removed in the previous commit.

pastilhasandClaude Opus 5 911b79b6a2 drop a comment describing a machine that no longer exists
paths.ts carried a parenthetical explaining that the development machine had the
layout inverted — the project inside ~/dockers/officer.dev/, so the root derived
to officer.dev and the app store's directory came out as a dockers inside a
dockers.

That machine is gone. The project sits at ~/officerdev/platform, which is the
clean shape the comment said new installs would get. Anyone reading it now goes
looking for a directory that is not there and comes away unsure whether the
derivation can be trusted.

The rule above it is unchanged and is the whole contract: data/ is a direct child
of the root, and OFFICER_ROOT is dirname(DATA_PATH).

pastilhasandClaude Opus 5 cec8fbe57e the acl check could not fail, because sudo drops DATA_PATH
Review of 76cd7c2. The ACL finding is right and the fix is correct — verified here that `setfacl -R -P -b`
removes the default entries as well as the access ones, which the man page splits between -b and -k and
does not settle. `acl` is already a core package in setup.sh, so the new hard dependency is real.

But the checker it added cannot fail in the way it is documented to be run.

`assert-uid-free.sh` is invoked as `sudo ./assert-uid-free.sh --check ...`, and sudo's env_reset DROPS
DATA_PATH, so the script falls back to the hardcoded `/home/pastilhas/officerdev/data` — which is not this
machine's data directory and does not exist. Every check in the file is "look for X, report ok when nothing
is found", so a missing root reports clean without looking. Demonstrated: a tree carrying both
`user:65534:rwx` and `default:user:65534:rwx` was reported as `ok  no ACL entries naming uid 65534`.

The ACL check is the one that fails silently and completely, because it is the only one scoped to DATA_PATH
alone — the uid and subuid scans still walk /home and would catch something. So the check just added to
catch the hazard ownership cannot see is the check a wrong DATA_PATH disables.

Fixed by refusing rather than passing:

  require_roots       every search root must exist, or exit 2 naming it and showing the sudo invocation
                      that preserves DATA_PATH
  numeric guard       uid/start/count must be numbers. deprovisionOsAccount logs '<no-subuid-range>' in
                      that position for an account with no /etc/subuid entry, and pasting that log line in
                      — which is exactly how it is meant to be used — made sub_end empty and turned the
                      range scan into a no-op.

The handler's audit line now prints DATA_PATH inside the command it tells the operator to copy, and says
so explicitly when there is no subuid range rather than emitting a command that cannot work.

Verified: bogus root exits 2, non-numeric range exits 2, and the ACL check FAILS on a specimen tree
carrying the entries — the "make it fail before trusting it to pass" step from the spec's own subuid
section, now done for the ACL half too.

pastilhasandClaude Opus 5 76cd7c20bf sever the ACL as well as the ownership
severMemberTree reassigned the tree and left the access-control entries behind. confineUserTree
grants each member a named ACL on their whole tree — u:<uid>:rwx plus a default: copy — and
chown does not remove them: they are xattrs rather than ownership, and they record the uid
numerically.

Measured before this change: after chown -h -R to the service user, user:<uid>:rwx was still
present on the directory, on its children and in their defaults. The tree read as the
platform's while still granting the freed uid read and write on every byte, so the next account
allocated that number would inherit the previous member's home, keys, credential and container
storage — the hazard this file exists to prevent, reached through a door that find -uid cannot
see.

Now chown then setfacl -R -P -b. Proven on a scratch tree: owner 1001 with five entries naming
1001 becomes owner 1000 with none.

-b rather than removing the member's entries alone, because the service user owns all of it
afterwards and "no ACLs" is cheaper to verify than "no ACL naming one id". -P is already the
default for a recursive setfacl — verified, a symlink out of the tree was not followed — and is
stated for the same reason the chown above carries -h: a member chooses what their symlinks
point at, and this argv should not rest on a traversal default holding.

Found by running assert-uid-free.sh against a real tree; the spec and the checker had the same
blind spot and were corrected in a2f63dc5.

pastilhasandClaude Opus 5 46799dada8 deprovision a member's linux account when the platform account goes
Implements docs/deprovision-os-account.md. Until now deleteUserHandler removed the row, cascaded the
database, and left the entire Linux side running — measured on production on 2026-08-12: working login
shell, healthy postgres container, 454M of data, uid queued for the next useradd to reissue along with
everything still owned by it.

The load-bearing rule from the spec: sever the data from the uid BEFORE releasing the uid, and if
severing fails, do not release. A failed deprovision is not a broken account, it is a trap for whoever
is created next.

Sequence: disable-linger, terminate-user, reap-and-prove, chown -R, userdel (never -r).

  reap    terminate-user is not a barrier. Production measured a three-hour-old `/bin/zsh -i` surviving
          it AND the removal of /run/user/<uid>. So: pkill, bounded wait, pkill -9, bounded wait, and a
          final count that must be zero or the account is not released.
  chown   fixes the uid and subuid halves in one pass — it rewrites every file it walks whatever owned
          it. The range is still captured first, because userdel removes the /etc/subuid entry and after
          that nothing on the machine remembers what it was. It is returned on every path including the
          failures, and logged as the exact assert-uid-free.sh command line.

Two guards the spec did not ask for, both pure and unit-tested:

  guardDeletable    ensureOsUser's adoption rule backwards. Deletable only if the passwd home is the one
                    the platform would have confined, and uid >= 1000. Without it `userdel root` is one
                    bad users.osUser away and nothing else in the sequence would object.
  guardMemberTree   the tree must resolve to a direct child of DATA_PATH. The email reaches join() from a
                    database row and the result is the argument to a recursive chown.

chown runs with -h. Measured here that `chown -R` already declines to follow a symlink out of the tree and
re-owns the link itself, but the argv should say so rather than rest on traversal semantics — and
re-owning links is what makes `find -uid` (lstat) a meaningful check afterwards.

destroy exists, has no call site, and is chown-then-delete-as-the-service-user rather than sudo rm -rf, so
a recursive root delete built from a database column does not exist in this codebase.

deleteUserHandler now runs this FIRST and refuses to delete the row if it fails: the row is what remembers
there is anything to clean up, so deleting it first makes a failure unrecoverable through the UI.

NOT YET RUN AGAINST A REAL ACCOUNT. Only the pure guards have tests. The five-step validation is in the
doc; it needs the production host, a shell left open, and a container writing as a non-root user — the two
cases the quiet path passes vacuously.

pastilhasandClaude Opus 5 f5f509a99d scripts/setup is the initial install, nothing else
Two of the eight did not belong. cleanup-desktop.sh is the teardown — the inverse of an install, not part
of one. provision-user-dirs.ts runs per account at invite time, on a machine that is already set up.
Both are back at the top level, with their `../` derivations and usage strings put back.

What is left is what a fresh machine runs once: the two installers (setup.sh, setup_mac_light.sh), the
two things setup.sh calls (setup-dockers.sh, setup-desktop.sh), and the two files they deploy —
starship.toml, copied to ~/.config, and officer-set-display.sh, which setup-desktop.sh installs to
~/.local/bin as a login-time mode setter. The last one is not a setup script and does not read like one;
it is here because it is install payload, same as the toml, and setup-desktop.sh loads it by
`$(dirname $0)`.

pastilhasandClaude Opus 5 9c353f5f0d move host setup into scripts/setup/
scripts/ was holding two unrelated kinds of thing: install-this-machine, and run-this-occasionally. The
eight installers now live in scripts/setup/; what stays at the top level is the build steps (gen-index,
prebuild, build/) and the two maintenance scripts (reindex-music, rebuild-soulseek-tree).

The move is not just a rename. Three of these derive the repo root from their own location:

  setup.sh:51            PROJECT_DIR="$(dirname "$SCRIPT_DIR")"
  setup_mac_light.sh:51  same
  cleanup-desktop.sh:134 ENV_FILE="$(dirname "$0")/../.env"

Left alone, all three would now resolve to scripts/ — and nothing downstream complains. PROJECT_DIR is
where .env is written, where `bun install`, `gen:index` and `db:push` run, and what pm2 is pointed at, so
a fresh install would have quietly provisioned scripts/ and reported success. cleanup-desktop.sh fails
the other way: it would find no .env, print "No .env — skipping", and leave the real VNC_PASSWORD in the
real file. All three are now `../..` with a comment saying why the level matters.

provision-user-dirs.ts imports data-path.ts relatively; that one tsgo caught.

Also disambiguated `setup.sh` where it had become two files. app-store/templates/<name>/setup.sh is a
per-sidecar installer with its own contract, and preflight.ts + docs/sidecar-app-store.md discussed both
in the same paragraph. The host one is now spelled with its full path at those sites.

Verified: bash -n on all six shell scripts, tsgo clean, os-user tests pass, both derivations resolve to
the repo root, starship.toml still resolves from os-user-shell.ts, and provision-user-dirs.ts runs under
DRY_RUN.

pastilhasandClaude Opus 5 ec1997fd0e a chat with no chosen directory runs in the caller's own home
The default was DATA_PATH/<email>/general_chat_sessions, a dedicated directory so /chat
sessions formed their own Claude project group instead of cluttering the home. It is a sibling
of the home, and confineUserTree makes every sibling the platform's at 0700 because the others
are attachments and email_accounts. So it was unreachable for a member: the first live member
turn started there and every Bash call failed on its own working directory before doing
anything.

A per-member copy inside each home fixed the symptom and left two rules to remember. The owner
chose one rule instead — the account's own home, whoever they are — and accepted the trade
knowingly: /chat sessions now share a project group with anything else run from that home,
which was the reason the dedicated directory existed.

Removed rather than left dangling: getGeneralChatSessionsCwd, ensureGeneralChatSessionsCwd,
ensureMemberChatCwd, and general_chat_sessions from USER_DIRS so new accounts stop getting it.
Existing directories are untouched and their transcripts stay where they are — Claude groups by
cwd, so the owner's old /chat history remains under its own project slug rather than moving.

The UI labels move with it: the default group now reads "home" rather than naming a directory
that no longer has a role.

ChatIdentity keeps carrying both email and home. The pairing was justified in the comment by
general_chat_sessions being email-derived, which is now gone — but the distinction it encodes
is real (the email says who, the home says where), so the comment explains that instead.

pastilhasandClaude Opus 5 6c84c74c91 give a member a chat cwd they can actually enter
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.

pastilhasandClaude Opus 5 2a8f0049a3 handle OSC 52, so "press c to copy" reaches the user's clipboard
xterm.js does not handle OSC 52 unless something registers for it, and nothing did. A program
offering "press c to copy" emitted the sequence and it vanished, so its confirmation was true
about having sent it and false about anything arriving.

Found while signing a member into Claude Code on the production host: its first-run login
prints an OAuth URL too long to read off a wrapped pane and offers to copy it, "(Copied!)"
appeared, and the clipboard was untouched. The URL had to be recovered by running claude under
tmux on the server and reassembling it from the captured pane — which is not a thing a member
can be asked to do, and first-run login is every new member's first five minutes.

Writes only. A lone `?` in the data position is a read request — a program asking the terminal
to hand over whatever the user has copied — and it is deliberately not answered: a shell should
not be able to exfiltrate the clipboard of the person watching it.

The clipboard API needs a secure context and generally a user gesture; the keypress that caused
the sequence is that gesture. A refusal is swallowed rather than thrown, since a copy that does
not land is the status quo rather than a reason to break the pane.

pastilhasandClaude Opus 5 c59df4f866 let members use chat
The owner authorized this explicitly. Two refusals removed together, because
they were always one guard in two places: the wholesale isSuperAdmin middleware
in api/chat/chat.ts, and the chat socket's 403 in server.tsx.

They were right for the day they stood. A turn spawned claude as the OWNER and
every transcript path resolved through the owner's home, so a granted member
would have read the owner's sessions and run an agent as them.

What replaced them, rather than what deleted them:

  the turn runs as the member    spawnClaudeAsMember through sudo setpriv,
                                 proven against a real account by reading file
                                 ownership rather than trusting the process
  the credential is theirs       --reset-env plus an allowlist, so the owner's
                                 proxy variables cannot cross
  the transcripts are theirs     ChatIdentity carries a home from resolveHomeDir
                                 and claude-sessions cannot invent one
  the sessions are theirs        every session records its owner and all six
                                 sidecar commands refuse a mismatch

Also adds the precondition host asked for in 10: a member whose claude is not
signed in gets the instruction rather than a turn that dies on an auth error and
reads as a broken agent. Not installed and not signed in are separate messages
because they need different actions.

registry.ts and registry.test.ts now describe chat as confined in fact rather
than ahead of its implementation. The comments at both former guards say what
had to exist first, and that a revert should go back to a refusal rather than to
a narrower one.

pastilhasandClaude Opus 5 c5522700ff compare the binary as a string, and prove the uid by file ownership
host ran the live test against green. Two results.

SETPRIV WORKS. The privilege drop lands on the member and the SDK spawn survives
it, so the design does not change shape and everything layered on the hook
stays. That was the last question that could have moved the architecture.

THE BINARY CHECK REFUSED A BYTE-IDENTICAL PATH. sameFile used realpathSync,
which has to stat inside a 700 home the platform is `other` to, so it threw
EACCES and the catch turned that into "not their binary" — every member turn
refused forever, the moment the gates moved. Failing closed was the right
direction and it made the feature impossible rather than unsafe.

Now resolve(command) !== claudeBinIn(run.home). Both operands are computed by
the platform from the same function, so string equality establishes exactly what
the check is for and needs no access to their home. sameFile and its tests are
deleted: a helper kept for a case that cannot arise is a trap for the next
reader. The realpath version was defending against an upstream that normalises
paths, and there is no such upstream — the platform controls both ends.

The fact that decides this is that the check runs in the PLATFORM process, not
the member's, and neither of us stated it until EACCES did.

THE TEST WATCHED THE WRONG PROCESS. child.pid is sudo, whose real uid is
legitimately the service user's until it execs down through setpriv, so
asserting on it fails on a working drop. Split: --version through the hook
proves their binary ran, and a second spawn creates a file in their home whose
owner the test stats. Nothing self-reports, and a process cannot forge the uid
that owns a file it created.

pastilhasandClaude Opus 5 9bab67aca5 test the privilege drop without lifting a gate
host caught a circularity I had written twice: do not lift the chat gates until
a member turn has been watched running, but a member turn goes through chat and
chat refuses non-owners. With the gates up there is nothing to watch; with them
down the thing we wanted proven has already shipped.

spawn-as-member.live.test.ts calls spawnClaudeAsMember directly against a real
provisioned account — no gate, no chat, no SDK. The child's uid is read from
/proc/<pid>/status, so it is the kernel's answer rather than anything the child
chose to say, and it asserts >=1000 and not this process's uid: a failed
privilege drop cannot pass by running as the service user. It also asserts the
binary exited 0 having printed a version, which proves their install ran rather
than merely being spawned, plus a negative that /bin/sh through the same hook
throws.

Opt-in via OFFICER_TEST_MEMBER and OFFICER_TEST_MEMBER_HOME, because it needs a
provisioned member with claude installed — which exists on the production host
and on no developer machine. A run without them skips loudly rather than
reporting an empty file as a pass.

Also adopted host's NO REPLY NEEDED terminator: "reply to everything" had no
exit condition and cost the owner two agents being polite at each other.

pastilhasandClaude Opus 5 1575df3f78 stop building cwds out of an email address
host found a live regression from 95951fb, on the owner's own paths.

resolveBaseCwd used to take an email and resolve its own root. 95951fb made the
first parameter the home itself, and three callers outside that diff kept
passing an email: pipeline-executor twice and agent-handoff once. Both
parameters are string, so tsgo had nothing to say. Every pipeline step and
handoff with a relative cwd, a `~`, or no cwd was building a path out of an
address, resolving it against the platform's own working directory — the
checkout. Absolute paths kept working, which is what would have made it look
intermittent.

All three are owner-only, so they now pass getOwnerHomeDir(email) explicitly,
the way agent-runner does. The definition of resolveBaseCwd carries the warning:
an absolute path, NOT an email, with the reason.

Not done: the branded type this argues for. Two strings meaning "identity" and
"filesystem path" sat adjacent through a refactor and the compiler could not
help, which is a real gap — but it reaches every path function in the server,
and doing it at 01:00 on the back of a bug caused by a hasty refactor would be
the joke telling itself.

pastilhasandClaude Opus 5 95951fbe5a resolve transcripts and cwd against the caller's home, not the owner's
The history layer, and the last change that could be made without a live member.

claude-sessions.ts had `claudeHome = process.env.HOME_DIR ?? join(DATA_PATH,
email, 'home')`, which discards its argument whenever HOME_DIR is set — always,
on a real install. Every transcript read therefore resolved to the OWNER'S
~/.claude no matter who asked, and the comment above it asserted "single-user
platform" as though that were a property rather than an assumption. A member
reaching these functions would have been handed the owner's conversation list.

Now every read takes a ChatIdentity {email, home} with the home resolved from
resolveHomeDir(userId), and this file has no way to invent one. Both fields
travel together because they are genuinely different: general_chat_sessions
lives under DATA_PATH/<email>, not under a home. Collapsing them would be the
same class of mistake as undefined meaning "the owner".

websocket.ts's resolveCwd takes a home, so `~` expands against the caller's own.
Identity is resolved BEFORE the cwd — expanding `~` before knowing whose home it
is would be exactly the bug being removed — which also let a duplicate
resolveTurnIdentity call from 6aeb304 be deleted.

chat.ts resolves per request and throws FORBIDDEN rather than falling back, same
posture as resolveTurnIdentity. agent-runner passes the owner's home explicitly
rather than inheriting it, since that path really is owner-only.

Made at 01:00 after saying it should not be. Three things I am least sure of are
listed in COMMS 29 rather than left for the reviewer to find: chat routes now
have a failure mode they did not have, resolveBaseCwd's exported parameter
changed meaning rather than shape, and the bare-email rewrite in chat.ts was
mechanical with hand repair.

pastilhasandClaude Opus 5 6aeb304f56 never spell "I don't know whose turn this is" as "the owner"
host caught that resolveMemberRun failed open. Returning undefined means "run as
the server owner" downstream — their binary, their ~/.claude credential, their
HOME, their MCP config carrying OFFICER_AUTH_TOKEN — and three different inputs
produced it: the caller being the owner, resolveHomeDir failing, and a member
whose osUser is null. The last two mean "could not determine", and answering
them with the owner's identity is the single thing this feature exists to
prevent.

23's own comment said the caller must not fall back to the owner. The code did
exactly that. The prose was right.

Now a discriminated TurnIdentity: owner, member, or refuse-with-a-reason. The
call site ends the turn on refuse instead of spawning. The owner's identity is
reachable only by positively establishing isOwner, never by failing to establish
anything else — resolveHomeDir already reported it as a positive fact and the
funnel through undefined was the only thing discarding it.

The null-osUser case is not hypothetical: provisionOsAccount is non-fatal at
every stage and records the account either way, as its own source says. Tonight
provisioning failed three separate ways on a real member and the account
survived each time.

No test yet, and the reason is in COMMS rather than hidden: it needs database
fakes this repo has no pattern for, and inventing one at 01:00 to cover four
branches is how the next defect gets written. The union is exhaustive, so tsgo
catches a missing case — not the same thing, not nothing.

The last mechanical link: chat socket -> resolveMemberRun(userId) ->
ClaudeSpawnStreamingParams.member -> claude-manager's branch ->
spawnClaudeAsMember -> sudo setpriv. The path from a request to a privilege drop
is now complete.

Resolved from the authenticated socket, never from the client message — the same
rule server.tsx applies to the pty sidecar, where it deletes any client-supplied
osUser/home from the query string before setting its own.

resolveMemberRun returns undefined rather than throwing when a home cannot be
resolved, because undefined means "the owner" downstream: an account with no
Linux user has nothing to confine a turn to, and falling back to the owner is
the one wrong answer that must not happen by accident. A separate function with
that reasoning attached rather than an inline ternary.

Still inert. Both gates refuse non-owners before this line is reached, so the
only path that reaches it today returns undefined via isOwner.

pastilhasandClaude Opus 5 8c4f150c15 stop one conversation's transport hiccup from killing every session
host found this while we were elsewhere: four agent-sidecar crashes tonight, one
truncating the owner's turn mid-sentence.

  error: ProcessTransport is not ready for writing
      at write (…/claude-agent-sdk/sdk.mjs)   <- no frames from our code

A floating rejection inside the SDK's own input pump, so no await of ours could
have caught it. With no handler anywhere in src/servers it reached the top
level, Bun exited, PM2 restarted, and every live session on the machine died —
not just the one whose transport failed.

That is 975673a for the second time. It fixed the one path someone had thought
of, a Postgres query throwing, and its own message named the consequence: "any
Postgres restart killed every live agent session on the machine". The general
case had no backstop.

Now logged loudly and survived. This does not pretend an unhandled rejection is
fine — it makes it debuggable instead of fatal.

uncaughtException is deliberately not handled the same way: a rejection leaves
the process's state intact, a synchronous throw that unwound to the top may not
have, and continuing on a corrupted heap is worse than restarting. Same blast
radius either way, which argues for durable sessions rather than for surviving
anything at any cost.

The trigger is untouched and unconfirmed — most likely the CLI exiting while
streamInput is still pumping. That needs catching in the act on the live host.

Also worth knowing, since d59adbf interacts: this restart sweep runs several
times an hour on that machine, and a session with no recorded userId is now
skipped rather than asked about, so it stays marked generating until a
reconnect. A stuck "generating" spinner after an agent restart is that, not the
UI.

pastilhasandClaude Opus 5 d59adbf1f2 scope the six sessionKey commands to their caller
The control surface half of 7cb402b, and the code-side blocker on the gates.
kill, interrupt, clear-session, is-generating, find-session and list all took a
bare sessionKey, so any caller who could reach them could act on whichever
session happened to match — and list returned every session in the sidecar,
which host rightly called a disclosure on its own, before anyone kills anything.

All six now carry userId, resolved from the authenticated request and never
taken from the client, and every handler enforces it through one ownedSession
helper. list is filtered rather than labelled. find-session is scoped because it
is the reattach hinge: a browser holding a transcript uuid it should not have
would otherwise be handed the session key that drives it.

"Not yours" and "does not exist" answer identically everywhere, which is the
same choice getClaudeSession made: every caller treats them the same, and a
distinct answer for the second confirms to a guesser that a session exists under
a key they do not own.

One behaviour change beyond the scoping. endTurnIfAgentIsGone sweeps sessions on
a sidecar restart, and a session with no recorded userId now has no safe id to
ask as — asking as the owner would answer a member's orphaned session with the
owner's authority. It is skipped, so it stays marked generating until the next
reconnect corrects it, which is what happened before that loop existed.

This removes the code-side reason the gates cannot move. It does not make them
movable: no member has signed in, no member turn has run, spawnClaudeCodeProcess
has still never been called, and lifting them was never mine to decide.

pastilhasandClaude Opus 5 9833822625 pass the member's gid instead of reusing their uid
host caught that provisionRootlessDocker had no gid field, so the new
install -d passed uid in the group position. Correct on this host only because
useradd allocates a per-user group; wrong on any account whose gid is not its
uid — one created by hand, one on a host whose login.defs uses a shared group,
or one ensureOsUser adopted rather than created.

Mode 700 means the group triad grants nothing, so nothing breaks today. That is
what makes it worth fixing now rather than later: it would surface only after
somebody widened the mode for an unrelated reason, and then not obviously.

The call site already held account.gid from ensureOsUser — the same value the
.local fix used correctly earlier the same night. Threaded through rather than
derived, and the field carries a comment saying why it is separate from uid,
since they are equal here and a reader would ask.

pastilhasandClaude Opus 5 893130940e create docker's storage ourselves, so the strip is not a race
host verified green's reprovision: claude 2.1.228 installs and runs as the
member, the file browser reads their home, rootless Docker runs and sees 0
containers while the owner has 8. First end-to-end proof of any of this.

One thing came out dirty. ~/.local/share/docker carried the home's inherited
default ACLs after a "successful" strip, because the strip was guarded on
existsSync and only the daemon creates that directory. On a first run the guard
was false and the strip no-opped; the retry then started the daemon, which
created the directory and inherited the defaults. The run meant to clean it up
was the one that made it, and the guard could not tell "nothing to strip" from
"nothing there yet".

Now created by us before the daemon exists — member-owned, 700, nothing to
inherit — and the strip is unconditional afterwards, repairing an account
provisioned before this and no-opping on a clean one. A guard that depends on
another process having got there first is a race however it is written; the fix
is owning the order rather than testing for it.

Third bug of this class tonight: an implicit parent directory, a strip guarded
on another process's work, and an installer piped into the wrong shell. All
three were invisible until a real member account existed, which is the argument
for making the second one sooner than feels necessary.

Left alone deliberately: .local being unreadable by the platform (a decision
about intent, not a defect, and the owner's), and the -u 70 + bind mount
observation, whose probe host already distrusts.

pastilhasandClaude Opus 5 ef000aaf51 pipe the installer into bash, and stop inventing a root-owned .local
Green's first provision failed three ways. host caught all three on the live
box; two are fixed here and the third is his to bisect.

THE INSTALLER IS BASH AND WE PIPED IT INTO SH. A script read on stdin never has
its shebang honoured — the interpreter you name is the one that runs it — and
install.sh declares #!/bin/bash and uses [[ =~ ]] on line 9. On Ubuntu /bin/sh
is dash, so it died with `Syntax error: "(" unexpected`, which reads like a
corrupt download rather than the wrong interpreter. scripts/setup.sh carried the
same line for the owner's own install and is fixed too.

INSTALL -D CREATED ~/.local AS ROOT. `install -d` makes missing parents but
applies -o/-g/-m only to the final component, so blessing ~/.local/dockers
invented a root:root .local inside the member's own home. Rootless Docker then
died on `mkdir …/.local/share: permission denied`, and the Claude installer
targets ~/.local/bin, so fixing the shell alone would have hit this next.

That is 71589ae for the second time — same function shape, same silent parent,
same class of consequence. Its own commit message said this surfaces "weeks
later as one tool mysteriously failing"; it took twenty minutes. Grepped the
other install -d/-D sites: os-user-shell already creates its parent explicitly,
os-user-ssh has no implicit parent.

NOT fixed: the file browser's ACL mask on a member home, where access mask is
--- while default:mask is rwx. That pattern means a chmod ran after the setfacl
and clamped only the access side, so the primitive is right and something later
is wrong. host has the live filesystem and has already half-excluded the
suspect; guessing from here would churn a working block. Noted that this commit
adds an install -d before the one he was about to bisect, so it wants a
reprovision first.

pastilhasandClaude Opus 5 7cb402b25a chat sessions record whose they are, and refuse a mismatched caller
host found this reading 10: chat sessions carry no identity at all. state.ts
held a flat sessionKey -> transcript uuid map, the in-memory sessions Map was
keyed the same way, and websocket.ts takes sessionKey and resumeSessionId
straight off the client message. 4d4a253f fixed exactly this for the pty
sidecar — "re-attaching to a session belonging to another account is refused,
otherwise a member resumes someone else's shell by guessing an id that travels
in a query string" — and chat never got the same treatment, because both gates
made it unreachable and therefore invisible.

Sessions now carry userId, persisted and in memory. getClaudeSession requires
the caller and returns undefined on a mismatch rather than throwing, since a
throw confirms that someone else's session exists. spawnClaudeStreaming throws
when a live session's owner does not match — that is the path that mattered
most, because handing over another account's sessionKey would otherwise push a
turn into their conversation and stream their agent's output back.

Legacy string entries are adopted to the owner on load. That is a statement
about the past rather than a guess: until this commit the gates refused every
non-owner, so nothing else could have created one. Dropping them would have
silently broken the owner's resume on upgrade.

PARTIAL, and the doc says so plainly: claude:kill, :interrupt, :clear-session,
:is-generating, :find-session and :list all still take a bare sessionKey with no
ownership check, and :list returns every session in the sidecar. Closing them is
a wide mechanical change across the protocol, the registry verbs and their
producers, and it belongs in its own reviewable commit rather than buried under
a state migration. The gates must not move on the strength of this one.

pastilhasandClaude Opus 5 3e0daee611 chmod the mcp config, because writeFileSync's mode never fires on it
host measured what df450318 assumed. writeFileSync passes `mode` to open(2),
which honours it only when it CREATES the file — on an existing one the call
truncates and writes and the mode is ignored. So the fix worked on a fresh
install and did nothing at all on every box already leaking, which is the whole
exposed population. Verified on production after the commit: still 0644, still
readable by a member.

That is worse than not fixing it, because it closes the ticket. The exposure
would have continued through every bootstrap with nobody watching for it.

chmodSync after the write, both kept — the creation mode closes the window
between open and chmod on a fresh write, and chmodSync is what reaches an
install that is already leaking. Commented so neither is deleted as redundant.

Still not closed on disk: the file is the owner's to chmod and the token is
theirs to rotate, and no commit reaches either.

pastilhasandClaude Opus 5 df4503180f stop handing a member's turn the owner's mcp config, and close the file
host found a live credential exposure while answering my question about what
else the member branch missed. It was outside the diff, and predates all of it.

MCP-CONFIG WAS NOT BRANCHED. mcpHostPath is module-level, written once at the
owner's bootstrap, and was applied to every turn. Its env block carries
OFFICER_AUTH_TOKEN, a 30-day JWT signing as the owner — so a member's turn would
have spawned their MCP server holding it. Now inside the params.member ternary
alongside the binary and the spawn, for the reason already written there: these
values say whose turn this is and have to move together. A member gets none.
What they should get instead is undecided, and undefined beats the owner's.

THE FILE WAS 0644. Written with a bare writeFileSync into a 755 directory, on a
host where `terminal` is granted to every role by default — so any member could
cat it and hold owner-level API access on loopback. host verified that as a real
member on the production host rather than reasoning about it. Now 0600.

The mode is the only half of that which is code. The token has been
world-readable and stays compromised until rotated, the directory chain above it
is still 755, and neither is fixable from a commit. Both written up for the
owner in COMMS 05, along with why I am stopping here rather than continuing:
the next commit should be the rotation, not more feature work stacked on top of
an open exposure.

pastilhasandClaude Opus 5 fbabc22ed7 wire the member branch into the SDK spawn, still unreachable
ClaudeSpawnStreamingParams takes an optional member {osUser, home}; createSession
branches on it, using their binary and spawnClaudeAsMember together, or the
owner's CLAUDE_BIN as before.

THE BINARY AND THE PRIVILEGE DROP ARE ONE BRANCH ON PURPOSE. settingSources
makes ~/.claude authoritative for settings and ~ is whatever HOME the process
gets, so pointing the SDK at a member's binary while spawning as the service
user would read the OWNER'S settings and credential while running the member's
code — and it would look like it worked.

cwd defaults to member.home before HOST_HOME for the same reason: HOST_HOME is
this process's home, so a member would start in a directory they cannot read and
the failure would present as a broken agent rather than a wrong cwd.

Nothing populates `member`. Both gates refuse non-owners before any of this is
reached, so the delta is that spawnClaudeAsMember now has two importers instead
of one, and neither path a user can take changes. Verified rather than assumed,
since host made it a condition: both gates intact, 84 tests pass.

Not authorization: host gave an opinion on wire-first and deferred to the owner,
who has not ruled. Corrected in COMMS, where 01 had overstated it. The gates
come off on the owner's word alone; this reverts as one commit if the answer is
no.

pastilhasandClaude Opus 5 baa2d29fa4 read the probe off stdout by position, and renumber comms
host's finding on 288679af, and the directory restructure the owner asked for.

THE MARKERS WERE SUBSTRINGS OF THE PATHS THEY TESTED. `bin` is inside
…/.local/bin/claude and `cred` is inside …/.claude/.credentials.json, and the
match ran against a string that merged stdout and stderr — so anything writing
either path to stderr set the flag. Verified on the live server against an
account with neither file: one `set -x` made the trace of the test command
itself report installed and signed in. Not live, and it fails in the unsafe
direction, on the endpoint whose whole job is explaining a broken agent.

No marker spelling fixes it, because a trace echoes the literal along with the
path. The channel was the bug. Two characters on stdout read by position, with
parsing extracted as parseLoginProbe so it cannot see stderr at all, and stderr
kept separately because a failure has to stay diagnosable. Seven tests including
the exact trace host captured — true/true before, false/false now.

COMMS is renumbered: ten dated files in a day, each restating the others'
status, replaced by one file holding only what nobody has resolved. Odd numbers
mine, even numbers host's, alternation encoding push-then-wait, numbers ending
when the feature does. The reasoning that produced the deleted files is in the
commit history, which is where it belongs.

Carried forward and unowned: deprovisionOsAccount, the terminal replay bug, the
two docker handbacks, and the two verify items neither of us can execute.

pastilhasandClaude Opus 5 288679af09 one sudo call for both agent-status answers, not two
host's finding on 6b7aad91. claudeLoginState ran two `runAs` probes in parallel,
and each is a `sudo -n setpriv` fork/exec that writes a line to
/var/log/auth.log. It is reached from /agent-status, which sits on a grant every
role holds by default, so a polling UI would have cost two sudo spawns and two
auth-log lines per poll per member — cheap individually, unbounded in aggregate,
and the auth log is where a real sudo event has to stay visible.

One call answering both questions with markers instead of two exit codes. Did
not take his second suggestion of caching `installed`: one call per request is
cheap enough that a second mechanism with its own invalidation is the worse
trade, and that judgement is recorded in COMMS so a polling UI can revisit it.

Also carries the verify list he asked for, including the pertento host key I
accepted on first use so git could reach his remote — he can compare it against
the server, which I cannot.

pastilhasandClaude Opus 5 6b7aad91db make both env guards able to fire, and follow the symlink
host was right twice, including about his own advice. Two dead guards had
shipped here, both for the same reason: written inside the spawn closure, where
the only way to reach them is to spawn — and the passing path spawns sudo. So
nothing ever demonstrated either one firing.

THE SUBSET CHECK WAS ALSO TAUTOLOGICAL. `permitted` came from the same constants
memberEnv builds childEnv from, so it was empty under every edit where that
holds — the exact criticism that retired NEVER_ENV. Worse, it lost the one live
trigger the denylist had: a credential added to ALLOWED_ENV used to throw, and
under the subset check widened the permitted set in the same motion and passed
silently. That is the realistic future edit and it was the one left unguarded.

Now both, and the denylist tests the LIST rather than the instance, so it fires
on exactly that edit. Extracted as `assertEnvSafe` so a test can pass a poisoned
allowlist — the guards being untestable in place is why they were decorative
twice.

THE BINARY CHECK WOULD HAVE THROWN ON EVERY TURN. Anthropic's installer puts a
symlink at ~/.local/bin/claude into a versioned directory; resolve() does not
follow symlinks, so the string compare matched only while `command` arrived as
the symlink spelling, and would have failed the moment anything upstream
normalised it — at exactly the point the hook gets wired. Compared through
realpathSync on both sides now, per turn and never cached, since `claude update`
moves the target.

Nine tests pin all of it: a poisoned allowlist, a stray key, each NEVER_ENV name,
and the symlink/target/missing-path cases.

pastilhasandClaude Opus 5 2bd96a9a98 tell a member why their agent is not working, instead of 403
f0af723 granted chat to every role by default, which is right, but the route
still refuses non-owners — so a new member gets a tile that resolves and an API
that 403s, the exact broken state b4f88ec and eda004a were built to remove.

The fix is not to withdraw the grant. It is to answer the question the member
actually has, which is "what do I do about it": their own claude, in their own
home, needs them to sign in once with their own Anthropic account. The platform
cannot do that for them — logging in is an interactive act against an account
that is theirs, and the alternative, pointing them at the owner's credential
proxy, spends the owner's subscription on their turns.

GET /api-status returns two booleans about the caller's own home plus the one
instruction that fits their case, so the UI can render a terminal saying "run
claude once" rather than an error.

Its own router, deliberately not on chatRouter: that router refuses every
non-owner wholesale and is right to — reads there leak the owner's project
directory names — which means an endpoint on it could not be read by the
accounts that need it most. Same `chat` capability, no owner gate, and nothing
in the response describes anyone but the caller.

Frontend not done: nothing calls this yet, so behaviour is still unchanged.

pastilhasandClaude Opus 5 6a85ca5d1f the binary check that was a comment, and a guard that could fire
Four fixes from the live server's review. One was a real defect.

THE BINARY WAS NEVER CHECKED. spawn-as-member passed `command` from the SDK
through untouched while a comment claimed the member's own install was what ran.
Since claude-manager resolves the OWNER'S CLAUDE_BIN at module load, wiring the
hook would have exec'd the owner's binary as the member — the precise confusion
this file exists to prevent, asserted in prose and enforced nowhere. Now throws
unless the command resolves to claudeBinIn(run.home).

NEVER_ENV COULD NOT FIRE. It tested an environment that memberEnv builds from
ALLOWED_ENV, so a denied name was already impossible; it was also missing six
credential variables the installed SDK reads. Replaced with the subset check the
reviewer proposed: anything not in ALLOWED_ENV or {HOME, CLAUDE_CONFIG_DIR} is a
leak whatever it is called. Complete by construction, and it cannot rot as the
SDK grows variables — which the denylist provably had already.

Also: one derivation of the binary path instead of two (install resolved from
the email, exec from the home — fine until they disagree), and the constraint
that ALLOWED_ENV may never hold a secret written at the list itself, since
`env K=V` in the argv is visible in /proc/<pid>/cmdline to every account.

Not acted on, and said so in COMMS: their finding that the 711 in 401dcb7 is
inert, and that a retrofit needs a mode pass. Both are theirs. Nor pulled chat
from DEFAULT_ROLE_CAPABILITIES despite agreeing a member currently sees a tile
that 403s — that is the owner's call, not a defect.

pastilhasandClaude Opus 5 62e98dff2e a member's claude is their own binary and their own login
First half of per-user Claude. Provisioning and the privilege drop, not yet
wired to a turn — the chat gates stay up and behaviour is unchanged for
everyone. Committed unfinished on purpose so the reasoning is on the record
before the server agent runs any of it; the state is written up in
COMMS/sidecar-app-store/2026-08-11-per-user-claude-handoff.md.

THE CLAIM THAT CHANGED. docs/per-user-linux-accounts.md:226-229 says the Agent
SDK "has nowhere to put a uid", so a member's turn has to become its own
process — a change of shape rather than a flag. It is a flag:
sdk.d.ts:951 exposes spawnClaudeCodeProcess, documented for exactly this ("run
Claude Code in VMs, containers, or remote environments"), and node's spawn
already satisfies the SpawnedProcess shape it wants. So no second sidecar, no
PM2 entry, no inverted transport, and none of the registry rework a second
instance would have forced (registration is name-keyed and evicts its
namesake; the nine claude verbs resolve by capability with no selector).

THE PLATFORM NEVER RUNS AS A MEMBER. The tempting reading of "each member runs
their own Claude" is a second officer-agent under their uid, and it is wrong:
that sidecar needs POSTGRES_URL and the JWT signing secret, so a member-uid
process holding them could read every account and sign a token as the owner —
strictly more than their shell can do, and already forbidden by the .env boot
check. The harness stays the service user's; the thing that runs the member's
code and holds the member's credential is theirs. That is the pty sidecar's
shape, not a new one.

PER-MEMBER BINARY, deliberately, over one shared /usr/local/bin/claude. The
private part is the credential, not the executable — but claude updates itself,
and a root-owned binary is one a member cannot update, which turns "my agent is
a version behind" into a request to the owner. Same installer the owner's own
install uses, run as them, in their home. Idempotent by skipping when present
rather than re-running: the retry button reprovisions on every press.

ALLOWLIST, NOT A FILTER, for the child's environment. At the moment of the call
the calling process holds POSTGRES_URL, the JWT secret and the owner's
ANTHROPIC_API_KEY; setpriv --reset-env means nothing crosses unless written
into the argv, so an allowlist is the complete answer to what a turn can see,
and a denylist would have to be right about every variable added later.
NEVER_ENV throws rather than leaks if someone widens it.

Login is the member's own act against their own account. The platform cannot do
it for them and must not try — the alternative is lending them the owner's
credential. claudeLoginState only reports whether the credential has appeared,
and reads it as the member, so a true answer means their process can reach it.

NOT VERIFIED: any of it at runtime. tsgo passes; nothing has been provisioned
and the spawn hook has never been called. If it turns out setpriv breaks how
the SDK reaches the process, this approach is wrong and the fallback is the
earlier plan.

pastilhasandClaude Opus 5 401dcb710c a blessed directory for container bind mounts
From a live-server report: a bind-mounted postgres:18-alpine crash-looped with
`mkdir: can't create directory '…/18/docker'` on a directory that already existed.

3bea46f stripped default ACLs from ~/.local/share/docker and I concluded the ACL problem
solved. It covered NAMED VOLUMES only. A bind source lives wherever the member put it, and
there the same collision returns by another route: the image's inner uid is 70, mapped
through the member's subuid range to 231141 — neither the service user nor the member, so
`other` — and the home carries default:other::--- from the file browser's ACLs. A named
volume passes with this bug present, which is exactly why the first fix looked complete.

~/.local/dockers is now provisioned as the documented place for compose bind mounts: mode
711, all ACLs removed. Two details that are the whole fix:

  711, not 700 — a container's inner uid is `other` and needs x to reach a bind source
  inside. No ACL can grant what the mode denies, and 700 blocks the path before any ACL is
  consulted. `r` stays off so nothing can list it, and the home above is still 700, so no
  other account can traverse this far anyway.

  setfacl -b, not -k — `-k` removes defaults but left mask::--- behind, so inherited named
  entries read as `user:pastilhas:rwx #effective:---`. An ACL that says one thing and means
  another is worse than none, and container storage wants ordinary mode bits.

Chosen over the alternatives: extending the strip cannot work when the member chooses the
path, and d:other::--x on the whole home loosens every directory forever to fix one local
case. Bounded deliberately — a bind mount from elsewhere in the home still hits the denial.
This is the place that works, not a promise about everywhere.

VERIFIED: the directory comes out `user::rwx group::--- other::--x` with no ACL and no
defaults, which is the design exactly.

NOT VERIFIED: a container actually starting from a bind mount in it. My host recycles uid
1001 across probe accounts and a stale /run/user/1001 — a systemd runtime mount that
survives rm — leaves the new account with no bus, so rootless Docker will not start here.
That is the deprovision/uid-reuse problem in the queue, hitting the test rig. The live
server is the place to confirm it: green is uid 1002 with no recycling, and the report that
prompted this came from there.

docs/per-user-linux-accounts.md line 337 predicted a milder version of this and said
"nothing does today". Corrected: something does, and the ACLs had removed the traverse bit
its 711 reasoning assumed.

DEFAULTS. Every role now starts with the three confined capabilities at write, seeded in
bootstrap. These are what the platform is FOR — an account that signs in and reaches none of
them is not restricted, it is useless, and making the owner grant them by hand first is a
step with no decision in it.

Seeded as real rows rather than implied by absence, which keeps the table's one rule intact:
a missing row means no access, always, with no exception to remember. Revoking one therefore
works like revoking anything else — the row goes and nothing puts it back. Done in bootstrap
because that happens exactly once per install, so seeding can never fight a later revocation.
Non-fatal: an owner whose roles hold nothing is a one-click fix, while failing bootstrap over
it leaves a platform with no account at all.

`app` capabilities are deliberately not defaulted — they reach data the owner may not intend
to share, and each needs a sidecar before it means anything.

SCREEN. Role selection is tabs rather than a dropdown: three roles are the axis you move
along, and a select hid two of them behind a click while giving no sense of which one you are
editing. Row descriptions are gone — with three rows called Terminal, Chat and Files they
explained nothing — and the "needs a Linux account" warning went with them, since every
account now gets one at creation, so it was noise about a state that no longer occurs on its
own. `needsOsAccount` is removed from the API too, not just hidden.

pastilhasandClaude Opus 5 3bea46f2d7 rootless docker per member — provisioning works, running a container does not yet
Not finished. Committed because the diagnosis is worth more than the code.

WHY ROOTLESS AND NOT THE DOCKER GROUP. `usermod -aG docker <user>` is the one-line version
and it is root: `docker run -v /:/host -it alpine chroot /host` is a root shell, which reads
.env, every other member's home and the wallet seed. Every boundary from today, bypassed by
one documented command. Rootless gives what was actually asked for — a daemon per account,
containers in that account's user namespace, images in their own home.

VERIFIED on this host: provisioning succeeds, the server reports 29.5.0, the daemon runs as
the member, `docker pull` puts 403 MB under their own home, and `docker ps -a` shows nothing
while the owner has four containers. That last line is the isolation, measured.

NOT VERIFIED: actually running a container. It failed, and the cause is an interaction
between two things built today:

  failed to copy xattrs: failed to set xattr "system.posix_acl_default" on …/volumes/…/_data

Creating a volume copies xattrs, and the DEFAULT ACLs on a member's home — added so the file
browser could read their files — are inherited by Docker's storage, where a mapped id inside
a user namespace is not a valid id to set. Both features correct alone. The fix here strips
default ACLs from ~/.local/share/docker only, leaving the access ACLs the file browser needs.

That fix is UNPROVEN. The re-test failed for a different, environmental reason: probe users
recycle uid 1001, and a stale lingering systemd user manager from a previous probe answered
`systemctl --user`, so the unit appeared not to exist. Cleaned with `loginctl terminate-user`.
Retest on a machine that has not had a uid-1001 user, or on a fresh uid.

Also worth knowing before this ships: uid reuse after deleting a member is a real hazard, not
just a test artefact — the next member gets the previous member's uid, and anything left
lingering belongs to them.

setup.sh gains uidmap and dbus-user-session as core packages; the shell template exports
DOCKER_HOST from $XDG_RUNTIME_DIR when the socket exists.

pastilhasandClaude Opus 5 71589aee99 a member's terminal looks like the owner's
A new Linux account opens a shell with nothing: useradd copies /etc/skel, which on Ubuntu
is a bash rc, and the account's shell is zsh — so it got no prompt, no history, no
completion, no colour. "Their own account" should not mean a worse terminal than the
owner's.

src/servers/shell-skel/zshrc is the template, and scripts/starship.toml is reused rather
than copied: setup.sh already deploys it for the owner, so one file serves both audiences
and they cannot drift. Seeded by provisionOsAccount, which means the retry button applies
it to accounts that already exist — no delete-and-recreate.

The template depends on nothing but zsh. Starship, eza, nvim, bun, deno and cargo are each
used only if present, and every path is $HOME-relative — the owner's own .zshrc has three
absolute /home/pastilhas paths in it, which is exactly what a template must not inherit.
Without starship it falls back to a zsh prompt showing the same information, because a
shell that opens with a broken prompt reads as a broken machine.

Never overwrites: written only when the file is ABSENT. ~/.zshrc.local is sourced last and
never written, so there is somewhere to put your own config that no future template can
reach.

Three fixes found by running it:

- install -D creates missing parents but applies -o/-g only to the FILE, so ~/.config came
  out root:root — readable but not writable by its owner, which would have surfaced weeks
  later as one tool mysteriously failing. The parent is now created explicitly.
- useradd took its shell from process.env.SHELL, which under PM2 is whatever PM2 was
  launched from. A member's shell depended on how the server happened to be started. Now
  chosen from what is installed: zsh, else bash.
- the pty sidecar spawned ITS $SHELL for a member, not theirs. It now execs their passwd
  shell via sh -c, so the login shell in /etc/passwd is the one they get.

starship moves out of the light-profile skip. The light profile exists to serve a file
browser, a terminal and chat — the terminal is one of its three reasons to be, and it is
what every member gets. Leaving starship out meant the fallback prompt on exactly the
installs most likely to have members. oh-my-zsh, eza and lazygit stay full-only.

Verified in a real member shell: zsh from passwd, HISTFILE in their own home, eza-backed
ll, starship active, EDITOR=nvim, and an edit to .zshrc surviving a reprovision.

pastilhas e4acf19a35 Merge remote-tracking branch 'gitea/master' into sidecar-app-store 2026-08-11 19:10:52 +00:00
pastilhasandClaude Opus 5 4d4a253f72 terminal runs as the member; chat is grantable and still refused
TERMINAL is confined now, and the shell is genuinely theirs. The pty sidecar spawns it
through sudo setpriv as their own account, in their own home, with the platform's
environment cleared. Verified end to end against the sidecar's own socket:

  id -u                    1001, not 1000
  file the shell wrote      owned by ptyprobe
  ps -o user=,args=         ptyprobe /bin/zsh -i
  env | grep -c POSTGRES    0

osUser and home are resolved in upgradeWs from the authenticated account, and whatever
the browser sent under those names is DELETED first. The bridge forwards the query string
to the sidecar untouched and the sidecar starts a shell from what it finds there, so
trusting the client for either would let a member ask for the owner's uid in a query
parameter.

node-pty does support uid/gid, unlike Bun.spawn, and they are deliberately unused: they
set the ids without applying the account's groups or resetting the environment, so the
shell would keep the owner's groups and everything Bun loaded from .env.

Also closes the pty identity blindness in TODO.md. Sessions record whose they are, list
and kill scope to the caller, and re-attaching to a session belonging to another account
is refused — otherwise a member resumes someone else's shell by guessing an id that
travels in a query string. Measured: member killing the owner's session -> ok:false,
owner killing it -> ok:true.

CHAT is confined so the owner can grant it and the route resolves, and both execution
doors refuse a non-owner: the router wholesale, and the socket in server.tsx. The agent
has not moved — the SDK spawns claude itself with nowhere to put a uid, and every
transcript path resolves through the owner's home, so a member would read the owner's
session list and run an agent as the owner. Reads are refused too, because
listClaudePwds returns the names of the owner's projects.

A deliberate, temporary gap at the owner's request: permission and route now, function
when a turn can be spawned under runAs with the member's own HOME. Both guards say so,
and the registry test names them so a future edit cannot move one without the other.

pastilhasandClaude Opus 5 eda004a46d a naked platform does not describe what it does not have
Reversing my own call from an hour ago. I built the denied-route screen to EXPLAIN the
absence — "Music is not installed", with a link to the app store — and argued a redirect
erases what you asked for. The owner's correction is the better principle: a server should
not know about a sidecar it does not have. Explaining Music is the app describing a feature
that, as far as this install is concerned, does not exist, and it leaks the whole catalogue
of what could be installed to any member who types a URL.

So a denied path is now indistinguishable from an unknown one: redirect home, the same
answer App.tsx's path="*" already gave. One behaviour for a member without a grant, an
owner without the sidecar, and a typo. Nothing disclosed.

The Permissions screen loses both explanatory blocks for the same reason. One listed every
capability whose sidecar is absent — a catalogue of uninstallable features presented as a
permissions decision. The other described chat, tasks, the desktop and the wallet as
"not grantable" to an owner who may have none of them installed. `notInstalled` is gone
from the API too, not just hidden in the UI. What is on that screen is what this server can
actually do.

Still short of what the owner described, and worth naming rather than implying otherwise:
routes are DECLARED in App.tsx for every screen and this hides the ones that should not
resolve. The end state is routes REGISTERED from the manifests of installed sidecars, so an
uninstalled feature has no route to hide. The manifests already exist and the dock is
already built from them; the router is not, yet.

pastilhasandClaude Opus 5 b4f88ec161 routes refuse at the route, and a new home is empty
Three things, from a member sitting on /music with no music capability on a server with
no music sidecar: an empty library, and 403s in the console.

PERMISSIONS AT THE ROUTE. `canVisit` filtered the dock and nothing else, so the tile was
hidden and the route was wide open — typing the path, following an old link or restoring
a tab rendered the screen anyway. RouteGate now wraps every screen in one place, inside
the error boundary.

It does not redirect. Sending someone to `/` erases what they asked for and reads as a
bug: they clicked Music and landed on Home. It says why instead, and the URL stays put so
a reload after installing the thing just works.

And it says which of the two reasons applies, because they need different screens and send
the reader to different places. `not-installed` is a fact about the SERVER — the owner gets
a link to the app store. `not-granted` is a fact about the ACCOUNT, and only the owner can
change it. Presenting either as the other sends you looking in the wrong place.

ROUTES FOLLOW THE SIDECAR. Free, once the above exists: `deniedRoutes` already covers
"held but its sidecar is not installed", so an uninstalled feature has no tile AND no
screen. The dock, the Permissions list and the routes now agree because they read one
answer.

NO MORE SEEDING. Downloads/Documents/Music/Videos/Pictures are gone from both places that
made them — the member's provisioning and, older and worse, `/ls`, which created folders in
somebody's home as a side effect of LOOKING at it. A listing that invents its own contents
is a listing you cannot trust, and the platform has no standing to choose a person's folder
layout. A new home is empty.

pastilhasandClaude Opus 5 4b058a6703 fix the sign-out reload loop I shipped an hour ago
The 401 handler ended with location.replace('/'), guarded by "unless the path starts
with /signin". There is no /signin route — the sign-in screen IS path="/". So every 401
on the signed-out landing page navigated to the page it was already on, fetched again,
401'd again. A hard refresh loop with no way out of the tab.

The reload was never what fixed anything: useAuth already renders the sign-in screen
when there is no token. It only existed to drop a stale query cache. So it is now the
last thing attempted and bounded three separate ways, any one of which breaks a loop
alone:

  1. no token -> return. A 401 while already signed out is expected, not a revocation.
     This one alone ends it, because a reloaded document has nothing left to clear.
  2. once per document, module flag.
  3. once per tab, sessionStorage marker — which also covers a host that re-injects the
     token on every load, where clearing storage cannot help and guard 1 never fires.

Anyone stuck in the loop from the previous build: localStorage.clear() in the console.

pastilhasandClaude Opus 5 d3bed0add9 the file browser can actually read a member's home, and plans is gone
"This folder is empty" was a lie. The five seeded directories were sitting there and the
platform's readdir raised EACCES: a member's home is 700 and owned by them, which is
correct for a shell and locks out the file browser, which runs inside the platform
process. /ls caught the error and returned an empty listing, so a refusal looked exactly
like data.

Two doors, two boundaries, and that is the point rather than a compromise. The terminal
and the agent RUN AS the member and the kernel is the boundary there. The file browser
acts on the member's behalf from inside the platform, which already applies its own
containment and is the owner's process on the owner's machine — it can read anything via
sudo regardless. Giving it access describes who is doing the work.

Done with named POSIX ACLs, because it has to hold in BOTH directions: a file the
platform writes must be editable by the member and vice versa. Mode bits cannot say that
— whichever party is neither owner nor group lands in "other", and widening "other"
opens the home to every account on the box. A shared group fails the same way, since both
parties would have to be in it and that puts every member in a group that can read every
other member's home. Two named entries plus `d:` defaults grant exactly two users and are
inherited by whatever either side creates, whatever their umask.

Verified: platform lists the home, member edits a platform-written file, platform edits a
member-written file, and a SECOND member is refused on both ls and cat.

/ls now distinguishes EACCES from a missing directory. An empty result is data and must
never be how a refusal looks.

acl joins the core packages in setup.sh — the alternative is an account that provisions
and then cannot list its own home.

Also: the file browser's own useTasks/useAgents fired /tasks, /agents and both category
endpoints on every render, which is where the last four 403s came from — they are the
context menu's Run Task and agent submenus, execution-only. Gated.

And plans is deleted: router, screen, routes, dock tile, hook, page title and its
capability. It read markdown from <repo>/plans, which does not exist. Fresh-install
Permissions is now Files alone, with Terminal to come.

pastilhasandClaude Opus 5 6b4fed68fd gitea leaves the baseline and becomes an app-store install
It was in both light profiles on the reasoning that it fronts a REMOTE instance and so
needs nothing installed locally. That is true and it was beside the point: a baseline
process appears in the dock and in the Permissions screen whether or not anyone ever
gave it a URL, so a fresh server offered to grant members access to a Gitea that did
not exist. "Is Gitea here" had two answers that could disagree.

Now it is `existing` mode with a URL and a token, like any other remote service, and
the one place that says whether it is here is the install row. No compose template and
no `provisioned` mode: Gitea is always something the owner already runs, and offering to
spin one up would mean owning its migration, backup and upgrade story.

members: 'none' — not because Gitea is single-tenant, it is the most per-user service
in the catalogue, but because there is nothing for the INSTALLER to do. The owner's
connection carries the instance; each member adds their own access token from /gitea and
acts only as themselves upstream. A provisioner would need an admin token and would mint
credentials on their behalf, which is more authority than this needs.

The catalogue test already pinned "the store offers exactly what light leaves out", so
removing it from the profile is what forced the entry to exist. Both light profiles
changed together — the mac one carried the same comment and the same gap.

Permissions on a fresh install is now Files and Plans. Plans stays because it reads the
platform's own shipped markdown from <repo>/plans, not anyone's disk, so it needs
nothing installed and exposes nothing.

pastilhasandClaude Opus 5 e393d0f5c2 a member's screens render, and the shell stops asking for things it cannot have
Three findings from granting Files to a role and signing in as the member.

THE BLANK SCREEN. WorkspaceView returns null until workspace.isLoaded, and isLoaded
was the success flag of GET /api/dashboards — which the `dashboards` capability gated.
So a member with files granted got a completely blank Files screen and no request to
/api/file-browser at all: the panel never mounted. Terminal, Chat and every other
workspace screen were the same.

/api/dashboards is not a feature. It is the per-user key-value store where every
screen keeps its layout, entirely `personal`, every row keyed to the caller. Gating it
does not restrict an account, it breaks it — which is the definition of `core` at the
top of the registry. Moved there.

And the failure mode was wrong independently: `isLoaded` now covers a failed fetch as
well as a successful one, with `loadFailed` for the difference, so a screen that cannot
remember its layout still renders with defaults instead of showing nothing and
explaining nothing.

THE STRAY REQUESTS. Six shell-level queries gated on isAuthenticated but not on
capability, so a member's first paint fired 403s at /server-settings/settings,
/jobs/counts (every three seconds, forever), /chat/models, /plans, /music/now-playing
and the chat access policy. Each now checks the capability it needs. JobsIndicator and
RescanButton also render nothing without `tasks` and `items` — the header was offering
two links to a screen the member cannot open and a button that would 403.

THE PERMISSIONS SCREEN. It listed all fourteen app capabilities on a server where none
of their sidecars are installed. Offering to grant Photos on a machine with no Immich
is not a permission decision. It now shows only what is installed, lists the rest as
"nothing installed for these yet" so their absence reads as a fact rather than a bug,
and marks confined rows as needing a Linux account. Fails open on a degraded read.

Found while checking that: the headscale catalogue entry claimed only the `headscale`
capability, but the same sidecar also serves `vpn` — a member enrolling their own
device — so vpn was never subtracted. Hence `alsoServes`.

pastilhasandClaude Opus 5 2c9d4e55aa retry a linux account in place instead of deleting the person
POST /users/:id/provision-linux, and a terminal button on each user row. One
operation covering three needs that were all previously answered by "delete the
account and make it again":

  backfill  an account created before the feature existed, or while the host was not
            set up for it
  retry     the first attempt failed for something since fixed — the traversable
            ancestor chmod being the one everybody hits once
  re-key    replace authorized_keys with a new public key

Deleting to redo a retryable side effect throws away the password, the dashboards and
everything else keyed to the row.

The provisioning block moves out of create-user into provisionOsAccount, shared by
both entry points for the same reason app-store/members.ts is shaped that way: two
moments, one piece of work.

Found by testing the retry rather than the create: provisionUserDirs re-chmods every
directory including home, and home belongs to the MEMBER after the first successful
run — chmod requires ownership, so it threw EPERM and took every retry down before it
started. Those chmods are now a default for directories being created, not an
assertion about ones that already exist; os-user.ts sets the home's mode through sudo
and is the authority for it.

The route answers 200 with the error in the body, because the interesting cases are
partial: "the account exists and is confined but the keys failed" is not nothing
having happened, and the row shows both halves.

Verified end to end: blocked ancestor reports the chmod and leaves osUser null, the
retry after that chmod succeeds and records the row, and a re-key replaces
authorized_keys without rotating the outbound key.

pastilhasandClaude Opus 5 ea0d2396f7 linux accounts use the chosen username, and refuse to take one over
Two changes, and the second is what makes the first safe.

The officer_ prefix is gone: a member's account is the username the owner typed, so
whoami says who they are and a commit from their checkout is attributed to something
recognisable. Measured first — useradd on this host accepts everything
validateUsername permits, including dots, hyphens, underscores and uppercase.

The prefix was also load-bearing, though, and not for looks. ensureOsUser REUSES an
existing account, which is what makes it re-runnable, and that was safe by
construction while only we created officer_* names. Unprefixed, adoption becomes the
dangerous path: a platform account named root would have found root in passwd, and
every runAs for that member would have been a root shell. So adoption now requires
the existing account's passwd home to be exactly the home we are about to confine —
that is what makes it ours — and any uid below 1000 is refused outright.

Verified: root and daemon refused as system accounts, and the owner's own username
refused by name with its real home quoted back.

Also, the ancestor trap from the first real install. A member's home is under
DATA_PATH, which is under the OWNER'S home, and /home/<owner> is 750 on Debian and
Ubuntu — so every mode bit on the account tree was right, the directory existed, and
the member still could not reach it for want of x four levels up. It surfaced as
"ssh-keygen: Could not stat …/.ssh: Permission denied", which points at the wrong
thing entirely. firstUntraversableAncestor now walks the chain as the member before
anything uses the home, and the error names the directory and the chmod.

The dev machine was already 751, and the probe used /tmp, so it never crossed the
ancestor that mattered. Worth remembering as a shape of mistake.

pastilhasandClaude Opus 5 0281ca62d2 a deleted or blocked account loses its session on the next request
Reported from two browser windows: an account deleted from the dashboard survived a
page refresh in the other one. Two independent halves.

Server: userMiddleware looked the account up, then read the result as
`dbUser?.passwordChangedAt` — so a DELETED account fell through the optional chain and
the request proceeded on a token that is still cryptographically valid, for up to the
full 30 days. `status` was the same hole from the other direction: signin refuses
anything that is not Active, but nothing rechecked it afterwards, so marking someone
Blocked did not end the session they already had, which is exactly when you would be
doing it. Now the account must exist and be Active on every request.

Client: nothing reacted to a 401 at all. onError fed the bug-report form and stopped
there, so the window kept rendering off cached React Query data. A 401 now clears every
storage key createClient reads and returns to the sign-in screen. /auth/ is exempt
because a wrong password is also a 401 and reloading the form would look like a crash.

window.officerBearerToken was declared non-optional, which made "there is no token"
unspeakable. It has always been one of five sources, any of which may be absent.

pastilhasandClaude Opus 5 4d513c0e13 files, for a member, in their own home
Introduces a fifth capability kind. `files` was `execution` — never grantable,
because it meant the OWNER'S filesystem. It is now `confined`: execution-shaped, but
the kernel enforces the boundary because the account has its own Linux user, its own
home, and no permission above it.

The rule that makes `confined` mean something lives in authorize.ts, once: a confined
grant is DROPPED for an account with no osUser. So "granted but unconfined" resolves
to no access rather than to the owner's home — which is what it would otherwise
resolve to, since getOwnerHomeDir ignores the email it is handed whenever HOME_DIR is
set. One rule covers the HTTP routes, the websocket doors and the dock, instead of
each router remembering.

resolveHomeDir(userId) is the new seam and it reads the row rather than the token, for
the same reason authorize.ts re-reads role: provisioning a Linux account for an
existing member has to take effect on the next request, not in thirty days.

The file browser resolves it in middleware and puts it on ctx user, because
getRootDir is called from fifteen places in that router. Making it async would have
meant editing fifteen call sites, and the cost of missing one is serving the owner's
home to a member. Now a handler cannot run without the answer.

Two things a real run caught:

- /ls seeds Downloads/Documents into the home as the service user, which is EPERM
  against a 700 home owned by the member — it took the whole listing down. Seeding is
  now best-effort there and happens at provision time instead, as the member.
- .unique() on os_user made db:push ask whether to TRUNCATE users, which is
  unanswerable non-interactively. uniqueIndex instead, per databases/CLAUDE.md.

Verified: a member without a Linux account is refused by name; with one, resolves to
their own home and NOT to HOME_DIR; the owner still resolves to HOME_DIR; and every
.. escape is refused while an absolute path is rebased under the root.

Terminal is still execution — that is the next stage.

pastilhasandClaude Opus 5 0fb9a29e64 ssh for a member's linux account, both directions
Inbound and outbound are two keys doing two jobs, and treating them as
alternatives breaks the goal:

  inbound   ~/.ssh/authorized_keys, from an optional public key the owner pastes
            on the create form. Their private half stays on their laptop.
  outbound  ~/.ssh/id_ed25519, generated in their home, never leaves the machine.

"They pasted a key, so skip generating one" is the obvious simplification. Agent
forwarding covers a human in an interactive session, but a platform-spawned agent
has no agent socket to borrow — so an edge checkout it is asked to commit and push
needs a key that lives on the box. The inbound key is therefore optional and the
outbound one is not.

No linux password, ever: useradd sets none, which blocks password login and does
not block key auth. So "real user, reachable over SSH, no password anywhere" is
the resting state, and the platform password stays the platform's business.

Validation is about line count, not key shape. Every line of authorized_keys is a
credential, so a pasted value with a newline would install a SECOND key silently.
Multi-line refused, a private key refused by name, an options prefix refused.

Every write goes through sudo install: the home is 700 and the member's, so the
service user cannot even create .ssh. install sets content, owner and mode in one
step, and content travels as a temp path so nothing quotes a form value into a
shell. ssh-keygen runs AS the member so the private key is never briefly root's.

known_hosts is not seeded — StrictHostKeyChecking accept-new instead. The Gitea
SSH endpoint is not knowable at create time, and the default setting makes a first
connection prompt, which in a non-interactive agent turn is a hang rather than an
error. accept-new still refuses a changed host key.

The generated public key is stored on the row and shown twice: on the after-create
panel and behind a key button on the user's row. It has an errand attached that
nothing else will remind anyone about — it must be added to their Gitea account.

Verified with a real useradd: .ssh 700 and id_ed25519 600 both owned by the member
and usable by them, authorized_keys byte-identical to the paste, no key rotation on
a second run, and a multi-line paste refused with authorized_keys untouched.
