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

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.

10 (amended again): chat sessions have no identity, and it should block the gates
Appending what is still missing to close per-user Claude, at the owner's request, into the
same unread file rather than opening 12.

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.

review fb2c5c28..6b7aad91: both guards fire now, one aggregate cost noted

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.

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.

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> |
