Architecture: the platform never runs as a member - -The owner's constraint, and the design follows it: **there is never a platform process running under a -member's uid.** The platform runs once as the service user and spawns everything. - -This also rules out the tempting reading of "each member runs their own Claude" — a second `officer-agent` -under their uid. It does not work, for a reason worth stating because it looks like plumbing and is actually a -boundary. That sidecar needs `POSTGRES_URL` (it imports `officerdb` at `user-instance.ts:19`) and the JWT -signing secret (it mints a 30-day owner token for the MCP tools at `user-instance.ts:72`). A member-uid -process holding those could read every account's data and sign a token as the owner — strictly more than -their shell can do. `docs/per-user-linux-accounts.md:60-82` already forbids this shape: `.env` is 600 and -`assertSecretsClosed` refuses to boot with `OFFICER_OS_USERS` on while it is group- or world-readable. - -So the split is: - -| | runs as | holds | -|---|---|---| -| `officer-agent` (the harness) | service user | DB, JWT, MCP config, session log | -| `claude` (the member's turn) | **the member** | their binary, their `~/.claude` credential, their home | - -This is the pty sidecar's established shape — one process, per-request identity, privileges dropped at the -point the member's code starts (`sidecar/pty/sessions.mjs:85-93`, `:113-125`).

What is in the tree - -### `src/servers/os-user-claude.ts` (new) - -- `provisionClaudeCli({email, osUser})` — runs `curl -fsSL https://claude.ai/install.sh | sh` **as the - member**, via `runAs`. Same installer the owner's own install uses (`scripts/setup.sh:853`), chosen there - for auto-update support. Per-member binary rather than a shared one is the owner's explicit decision: - everything Claude-related is user-specific, and a root-owned binary is one a member cannot update. -- Idempotent by **skipping when the binary is present**, not by re-running the installer. The retry button - reprovisions on every press; re-downloading would cost a network round trip per press and would quietly move - a member off a version they had updated to. -- `claudeLoginState({email, osUser})` — `{installed, loggedIn}`. Login marker is - `~/.claude/.credentials.json`, **not** `~/.claude.json` (which holds settings/history and appears on first - run regardless). -- Both checks run **as the member**, not as root. A `true` then means the member's own process can reach those - files, which is what the answer gets used to promise. This deviates from the earlier handoff §6.4, which - said "detect login by reading `~/.claude` as root" — deliberately. -- Never throws; returns a result. Same posture as SSH/shell/Docker in `provisionOsAccount`. - -### `src/servers/sidecar/claude/spawn-as-member.ts` (new) - -The `spawnClaudeCodeProcess` implementation, built on the existing `runAsArgv` (`os-user.ts:95`) — i.e. -`sudo -n setpriv --reuid --regid --init-groups --reset-env --`. - -- **Env is an allowlist, not a filter** (`ALLOWED_ENV`). At the moment of the call, the calling process's - environment contains `POSTGRES_URL`, the JWT secret and the owner's `ANTHROPIC_API_KEY`. A denylist would - have to be right about every variable that exists now and every one added later. `--reset-env` means - nothing crosses unless written into the argv (`os-user.ts:120-124`), so the allowlist is the complete - answer to "what can this turn see". -- `NEVER_ENV` throws rather than leaks if someone later widens the allowlist or the SDK starts merging its own - environment into `SpawnOptions.env`. -- Sets `HOME` and `CLAUDE_CONFIG_DIR` to the member's home explicitly. `--reset-env` already sets `HOME` from - their passwd entry, so `CLAUDE_CONFIG_DIR` is belt — but "which account's credential did this turn use" - should be answerable by reading one line. -- Uses `node:child_process`, not `Bun.spawn`: its return value satisfies `SpawnedProcess` (Bun gives web - streams and no emitter), and `Bun.spawn` silently ignores `uid`/`gid` anyway (`os-user.test.ts:23`). - -### `src/servers/api/users/provision-os.ts` (modified) - -`provisionClaudeCli` called after `seedShellConfig`, before `provisionRootlessDocker`. Non-fatal. Error -precedence is now ssh → claude → shell → docker. - ---- - -## 4. What is NOT wired — read this before testing - -**`spawn-as-member.ts` is never called.** `claude-manager.ts:350-352` still passes the owner's `CLAUDE_BIN` -(`:31`), `HOST_HOME` (`:35`) and `cleanEnv` (`:315`) into `query()`.

Do not lift them to "see if it works". - -Note `chat` is already granted at `write` for every role by default (`f0af723`, seeded at bootstrap), so the -permission is live and the route refusal is the only thing standing in the way. - -**Still owner-bound, untouched:** - -- `api/chat/claude-sessions.ts:25` — `claudeHome` is a private copy of the owner-home logic; discards its - `email` whenever `HOME_DIR` is set.

Zero occurrences anywhere in this repo before this - change. - -**ASSUMED, NOT TESTED — the whole list:** - -- That `provisionClaudeCli` succeeds for a real member.

Untested for the agent's paths specifically. - ---- - -## 6. Open questions and known risks - -**Network isolation is not solved and is not in scope of this change.** A member's `claude` has general -outbound reach — it must, to authenticate — which includes loopback, where the platform's own services -listen. `docs/per-user-linux-accounts.md:221-225` already says this plainly: not a sandbox; members are -isolated from each other and from accidents, not from the host. The terminal and rootless Docker have the same -property today. If "a member cannot reach the others or the outside" is a requirement rather than an -aspiration, it is a separate stage (per-uid firewalling or a network namespace) covering all three surfaces, -and it wants looking at **on the host that actually runs members** — not on the dev box. I probed the dev box -for this and the results say nothing about the deployment; disregard any such finding from me. - -**`curl … | sh` per member sits against this repo's supply-chain stance.** `bunfig.toml` sets -`frozenLockfile` precisely so nothing resolves that nobody chose, with the 2026-08-04 npm compromise as the -reasoning. This adds an unreviewed network fetch executed once per account creation. It is how the tool ships -and what the owner's own install does, and the owner accepted the trade — but it should be a conscious one, -not a thing discovered later in a diff. - -**`spawn-as-member.ts` has no test.** It is the one file standing between a member's turn and the owner's -credential, and the guarantee is currently a code-read. The test to write is in the shape of -`os-user.test.ts`: assert no `NEVER_ENV` name survives into the argv `runAsArgv` produces, and that `HOME` and -`CLAUDE_CONFIG_DIR` point inside the member's home. - -**Untested interaction with `claude-manager.ts`'s module-level state.** `CLAUDE_BIN` (`:31`) and `HOST_HOME` -(`:35`) are resolved once at import, from the *sidecar process's* environment. Both are wrong for a member and -both are what the wiring in §4 has to override per turn, not globally. - ---- - -## 7.
