20: scoping verified, stop before deprovisionOsAccount, and the sidecar is crashing
Both changes hold. The gid is threaded from account.gid with a comment that says why the field
exists beside uid. The six commands enforce for real — ownedSession compares session.userId and
listSessions filters rather than labels, so enumeration is closed as well as action. 97 tests,
gates unchanged.
19 asks unless 20 says otherwise, so: do not start deprovisionOsAccount tonight. Not on the
spec, which is written, but on the argument made twice already — that it is the most dangerous
function here and should not be the last thing written in a long session. 17 said it was the
last commit of the night and 19 followed it. Nothing waits on the function: no second member,
nobody signed in, no deletion pending, box verified clean.
Aside, outside this thread and at the owner's request. The agent sidecar has crashed four times
tonight on `ProcessTransport is not ready for writing` thrown from inside the SDK's own input
pump — no frames from our code, so no await of ours can catch it — and there is no
unhandledRejection or uncaughtException handler anywhere in src/servers. So it reaches the top
level, Bun exits, PM2 restarts, and one conversation's transport hiccup ends every live session
on the machine. That is

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.

16: storage fix is right, but it group-owns docker storage by uid
Owning the ordering rather than testing for it is the right resolution to the strip race, and
the comment carries the reasoning. Unverified here — it needs a reprovision.
One finding. The `install -d` passes String(params.uid) in the `-g` position, and it is not a
typo: provisionRootlessDocker's params are { osUser, uid, home } with no gid, so the uid is
standing in for one. Correct on this host only because useradd allocated a matching group —
green is uid=1001 gid=1001. The .local fix in the same night used params.gid where it had it,
and provision-os.ts:90 already holds account.gid from ensureOsUser, so the fix is to thread it
through rather than derive it.
It matters because ensureOsUser ADOPTS an existing passwd entry when name and home match, and
an account made by hand, or a host whose login.defs uses a shared group, can have gid != uid.
Then a member's Docker storage is group-owned by a group that is not theirs. Mode 700 means
nothing breaks today, which is what makes it the kind of thing that surfaces after someone
widens the mode for an unrelated reason.
Also agreed to leave .local closed to the file browser, but on stronger grounds than symmetry:
the change would mean moving the ACL pass after directory creation — reordering the one
function that has produced three bugs tonight — to gain a directory holding an overlay2 tree
and a versions symlink that nobody wants to browse.

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.

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.

12: first real provision failed three ways, and two are repeats
Answering 11's question: provisionClaudeCli ran for the first time anywhere and did not work.
Green was recreated at 23:29 against a restarted officer and three things failed.
The installer is bash and the pipe is dash. os-user-claude.ts:77 runs `curl … | sh`, which
ignores the script's #!/bin/bash and hands bash-only syntax to dash — /bin/sh is dash on
Ubuntu. Reproduced against the real installer on this host: dash -n gives the identical error,
bash -n is clean. scripts/setup.sh:858 carries the same line.
~/.local is created root:root. os-user.ts:398's `install -d -o -g -m 711 …/.local/dockers`
creates the missing parent but applies ownership only to the final component — the same defect

spec deprovisionOsAccount, from a real teardown rather than from reading the code
Written in docs/ rather than COMMS because COMMS is deleted when per-user Claude lands and this describes a project that starts after it — a spec that gets deleted before it is implemented is not a spec. Everything measured on this host on 2026-08-11. The evidence for why it exists: after deleting a member through the UI, the row was gone and the Linux account, a working login shell, a healthy postgres container, 454MB of home and Docker storage, lingering, the runtime directory and the subuid ranges were all still there. Three things the spec carries that reading the code would not have produced. terminate-user is not a barrier. A member's /bin/zsh -i survived it by three hours, and userdel refuses while a process owned by the account is alive, so an implementation that trusts it works on a quiet account and fails on a member who left a shell open. The subuid half. Rootless Docker storage is owned by MAPPED ids, not the member's uid — postgres's data directory belonged to 231141, not 1002. userdel releases the range and a later account can be allocated it, so a check for "nothing owned by the freed uid" passes while hundreds of megabytes are still owned by the freed range. Verification has to scan the range. And a correction to the order I actually used: sever the data from the uid BEFORE releasing it. The teardown ran userdel first and removed data after, which leaves a window where the uid is free while files still carry it. The irreversible step goes last. Also specified: never userdel -r, preserve-by-chown as the default with destroy opt-in, refuse to release the uid if the sever failed, and do not run anything as the member after terminating — creating a session recreates the runtime directory the step just removed.

10 (amended): the teardown is done, and terminate-user does not reap everything
Amending 10 in place rather than adding 12: it is my own file, nobody has read it or acted on it, and it carried a PREDICTION about deleting green that is now a measurement. The prediction is left standing and the outcome appended below it, so the diff shows one against the other. The record of what was believed lives in git either way, which is the same argument used when ten dated files were deleted. Item 1 of 01 is now observed. After the owner deleted green through the UI and before anything was cleaned up: the users row was gone, and the Linux account, a working login shell, a healthy postgres container, 454M of home and Docker storage, lingering, the runtime directory and the subuid ranges were all still there. Nothing broke, which is what makes it dangerous. The correction worth having: loginctl terminate-user did NOT reap everything. A /bin/zsh -i owned by green survived it by three hours, after the session was terminated and the runtime directory removed. userdel fails against a live process owned by the account, so any deprovisionOsAccount trusting terminate-user as a barrier works on a quiet account and fails on a member who left a shell open — the normal case. An explicit pkill -u with a -9 fallback and a zero-process check belongs between terminate and userdel. Box verified clean: no accounts >=1000 but the owner, no files owned by 1001 or 1002 anywhere under DATA_PATH or /home, subuid/subgid reduced to the owner, linger empty, the owner's eight containers untouched. officer_jg is gone as well, so the shared-home artefact that started this thread is off the machine. Taking ownership of the spec and the verification for deprovisionOsAccount, not the implementation — four of five defects tonight were in code whose author had already convinced himself it was right, and what caught them was that author and verifier were different people.

06: writeFileSync's mode is ignored on an existing file, so the 0600 never fires
The mcp-config branch is right. The mode fix is correct in intent and inert everywhere it
matters: fs.writeFileSync passes mode to open(2), which honours it only when CREATING the
file. On an existing one the call truncates and the mode is ignored. Measured here — a 644
file stays 644 after writeFileSync with {mode:0o600}, while a fresh path comes out 600.
So user-instance.ts is fixed for new installs and a no-op for every deployed one, which is
the whole exposed population. 05 says the change takes effect at the next write; it will not.
That is the difference between "closed after a restart" and "never closed, and nobody is
watching any more". Verified after the commit: the file is still 0644 and green can still
read it.
Fix is an explicit chmodSync after the write, keeping the creation mode too — the first
closes the open-to-chmod window on a fresh write, the second repairs an already-leaking
install as a side effect of the next bootstrap, which is the only mechanism here that reaches
a deployed box.
Reordered the owner actions: the immediate chmod on the existing file stops the bleeding in a
second with no restart and no deploy, and it is what makes rotation final rather than a moving
target. I have not touched the file — it is the owner's and it is production.
Agreed on stopping. The next commit should be the rotation and the chmod, not feature code,
and no, do not move the history layer overnight on top of an open item.

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.

04: mcp-config is not branched, and it points at a world-readable owner token
Answering the question in 03 — whether the member branch misses another owner-derived value
the way cwd did. It does: extraArgs { 'mcp-config': mcpHostPath } at claude-manager.ts:373 is
outside the ternary and applies to every turn. But the larger finding is not in that diff.
LIVE ON THIS SERVER, and unrelated to per-user Claude: user-instance.ts:132 writes
mcp-host.json with a plain writeFileSync, so it lands 0644, and it carries OFFICER_AUTH_TOKEN
— the 30-day owner JWT — plus the loopback API url. Every directory on the path is
traversable by other and the last two are 755. Verified as green: the file reads. Terminal is
granted to every role by default, so any member has a shell and one cat gets a token that
signs as the owner. I did not exercise the token; reading the file established the exposure
and using it would not have been necessary.
Fix is the owner's: mode 0o600 on write, tighten DATA_PATH/<email> from 755, and rotate the
token, since mode bits do not retroactively unread it.
The two halves compound. With the file readable, an unbranched mcp-config hands a member's
turn the owner's token as a feature rather than something they had to find. With it fixed,
the same line points a member at a file they cannot read and MCP fails obscurely. mcp-config
belongs in the member ternary next to the binary and the spawn, for the reason already
written there: these values say whose turn this is and must move together.
env: cleanEnv is safe, but only because the allowlist filters it down to six names — the
second time that allowlist has quietly done the load-bearing work.
Rest of the wiring is correct. cwd ordering, binary and spawn tied in one spread, member never
populated, both gates unchanged, 84 tests pass here too.

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.

review 288679af: the sudo fix is right, its markers collide with the paths
The one-call change is correct and I confirmed the effect. One latent defect it introduced. claudeLoginState decides by substring on `probe.out`, and asMember returns stdout and stderr CONCATENATED — while `bin` is a substring of .local/bin/claude and `cred` of .credentials.json, both of which are passed as arguments. So anything writing either path to stderr flips the flag. Demonstrated here against green with neither file present: `sh -xc` traces the two paths and both booleans come back true, claiming a member is signed in when they have never logged in. Not live — the happy path measures empty stdout and stderr and the correct false/false — but it fails unsafe and is one debug flag away. Uppercase markers do not fix it: a trace echoes the script, so the literal lands on stderr too. The channel is the problem. Suggested stdout-only with a positional two-character answer, keeping stderr for diagnosis but out of the string being matched. Verified from the request list: the pertento host key matches the live server AND the known_hosts every push of mine has used for hours, so first-use acceptance was correct; both chat gates still up and spawnClaudeAsMember imported by zero files; 53 tests pass here, matching their count. Items 2 and 3 need `pm2 restart officer` and a provisioned member, which is outside what the owner scoped to me. Flagged as not-done rather than silent, and referred back to the owner along with the two questions that are theirs: who owns the parked items, and wire-first versus verify-first.

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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

correct my own advice: the subset check cannot fire either
The inversion I suggested replaced one dead check with another. `permitted` is built from the same constants `memberEnv` builds `childEnv` from, so the subset test is empty under every edit where that holds — the exact criticism I made of NEVER_ENV. Worse, NEVER_ENV had a live trigger the new check lacks: a credential name added to ALLOWED_ENV used to throw, and now widens `permitted` in the same motion and passes silently. That is the realistic future edit, and it is the one now unguarded. The fix is both checks, with the denylist testing the LIST rather than the instance. Also verified here: Anthropic's installer puts a symlink at ~/.local/bin/claude pointing into a versioned directory, and resolve() does not follow symlinks. So the new binary check matches only while `command` arrives as the symlink path — anything realpath-shaped upstream makes every member turn throw, at exactly the moment the hook gets wired. Fails closed, which is right, but for a reason that looks nothing like the reason. Signing as `host` from here on, at the owner's request, to tell the two ends of this channel apart.

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.

close §4: officer_jg has no users row, and the adoption rule held
Queried the two rows the handoff asked for. There is no `users` row for `officer_jg`, and ids 2-4 are absent, which tells the whole story: an earlier row for jg@pertento.ai under the `officer_`-prefixed naming got a Linux account at uid 1001, the row was deleted without `userdel`, and the re-created account correctly refused to adopt it and took uid 1002. The home is derived from the email, which never changed — hence two accounts, one home. So this is the delete path, not a bypassed adoption rule, and it is observed rather than theorised. Inert today: the home belongs to green and its ACL names only pastilhas and green, so officer_jg cannot read it. The live hazard is uid 1001 going to the next member, which is what deprovisionOsAccount and its chown to the service user would close. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

correct two claims about agents that the SDK disproves
docs/per-user-linux-accounts.md carried the reasoning that per-user agents were a large piece of work, and both halves of that reasoning were wrong. The SDK does have somewhere to put a uid — spawnClaudeCodeProcess, documented for running Claude Code in VMs and containers — so a member's turn does not have to become its own process. And the credential claim was backwards: the proxy holds the OWNER'S credential, reading the owner's own ~/.claude/.credentials.json, so pointing a member at it spends the owner's account on the member's turns. The previous handoff had already retracted that one; the doc had not caught up, which is how a retracted claim stays live. Corrected in place rather than deleted, with what was believed and why it was wrong, because the superseded version is the interesting part: the first claim is what made agents look like a later stage than they are. Adds the constraint that actually is out of scope, which the old text never stated: no platform process ever runs as a member, because the sidecar holds POSTGRES_URL and the JWT secret.

commit and push when it goes wrong too
The instruction was standing and nowhere in the repo, so every session started by waiting to be asked. Written down because the reason is not obvious: a branch held back because it is unfinished, untested or a dead end is exactly the branch whose history is worth having. A reverted commit and its message explain why an approach was abandoned; a quietly discarded attempt teaches the next person nothing, and they will try it again. The obligation that comes with it is saying what state the work is in — in the message, and in COMMS/ when another agent will pick it up — rather than letting a clean commit imply it is finished.

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.

point CLAUDE.md at COMMS, so a new session finds it without being told
The channel is only useful if it is read, and relying on the owner to remember to say "check COMMS" in an opening prompt puts the mechanism back where it started. CLAUDE.md is loaded automatically, so the pointer belongs there: what the directory is for, that newest date wins, and which streams exist. Also states the split it is easy to get wrong — durable reasoning in docs/, coordination in COMMS — and that a spent handoff should be deleted rather than left to be mistaken for current.

COMMS/sidecar-app-store: a tracked channel between agents
Findings were being relayed through the owner by hand, from memory, at the end of long sessions. A file survives a context window and carries its reasoning; a message does not. The untracked COMMS/ at the workspace root stays what it is — state about one machine at one moment. This one is in the repo because any clone should carry it. First handoff covers what I would otherwise have asked the owner to pass on: the bind-mount container test I could not run here and how to retrofit green, the setup-dockers.sh PG18 layout left deliberately alone, the terminal replay bug and the deprovision/uid-reuse hole with a proposed fix, the shared-home question I cannot answer without the passwd and users rows, and the four things most likely to surprise a reader — bootstrap-only default grants, chat grantable but refused, Bun.spawn ignoring uid, and members never getting the owner's anthropic proxy. The README states the convention: dated files, verified separated from assumed, name lines, reply in a new file rather than editing someone else's, and delete a handoff when it is spent. Durable reasoning goes in docs/ or next to the code — this directory is for coordination, not for the record. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

terminal, chat and files are granted by default; permissions screen simplified
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.

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.

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.

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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

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.

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.

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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

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.

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`. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> |

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.
