Server mode can now run each account as its own Linux user (ah-<name>)
when `agenthub server install-system` has set S3 up. The dashboard
reaches a member only through sudo -u / write-as / pane-launch, reads a
member's files only through owner- and type-checked opens, and hooks
are authenticated by peer uid. Local mode and server mode without S3
are unchanged.
EXPERIMENTAL: tested with fake sudo and fake accounts only. It has not
yet been verified on a real install with real member accounts, sudo or
a real Codex login. Do not offer it to real users yet.
- S3 core: provisioning, per-member tmux servers, the proxy key
gateway, shared tools in /opt, dropped capabilities for children
(P0–P5)
- P4: plan and quota per member home
- P6: ~/.claude.json seed; opt-in plugin baseline installed as the
member; managed-settings spike script (not run)
- P7: Codex account pool (`agenthub accounts add --tool codex`)
- Roles merged with main's admin / analyst / developer: analysts write
only their own rows, under S3 as well
- Per-account prefs: one implementation (Chat UI + onboarding)
- Security reviews F1–F49 (five rounds), each fix with a regression
test: symlink/TOCTOU-safe member reads, no host writes in a member
home, credentials and the data dir never served, owner and folder
account must agree, pane tokens bound to the pane's uid, bounded
sudo/tmux/git calls and member reads (no hang or crash from a member),
async route rejections answer 500 instead of exiting
- Docs: docs/SERVER-MODE.md (S3 model, accepted ceilings, operator
runbook), docs/plans/server-mode/S3-PLAN.md, CLAUDE.md S3 rules
Tests: server 2838/2841 (3 need 127.0.0.1:3000, held on this box);
client 1162/1162; tsc clean; headers check passes.

The Memory tab could only show this machine's user memory and the
dashboard's own project file. Setting up a project you had not run
through the dashboard meant opening a terminal — `PUT /file`'s
"project" scope always resolves against the server's cwd, on purpose.
Add one narrow route per tool that writes into the directory you name:
CLAUDE.md for Claude Code, AGENTS.md for Codex, both through the same
`project-memory.js`. Being the only write path that honours a
caller-supplied directory, it pays for that:
- the directory must be absolute and already exist — nothing is
created for you;
- the filename comes from the route, never from the body;
- an existing file, symlink included, is a 409 — this can only
create, never overwrite;
- it sits behind the loopback-Origin guard /api/run uses, so a page
in the user's browser cannot plant agent instructions in a project
directory. That guard moves to lib/same-origin.js to be shared.
The modal takes the dashboard's known project dirs as suggestions on a
free-text input rather than a closed list: a project it has never seen
is exactly the case this exists for.
Mutation-checked: dropping the origin guard, and swapping lstat for
stat, each fail a test.
Plugins/marketplaces GET routes were silently empty because codex-cli.js
never unwrapped the CLI's {installed,available}/{marketplaces} objects
into arrays; backup writes bypassed the symlink-escape guard entirely;
readFileSafe was stricter than every other Codex reader, showing a
symlinked skill/rule in the list and then refusing to open it;
marketplaceAdd only accepted http(s) URLs, rejecting owner/repo sources
the CLI itself takes. Also: docs drift, a dead i18n key, and a scope-cast
hazard in the shared Editor/ConfirmDelete modals.
Fixes, one per finding: unwrap installed/marketplaces in codex-cli.js so
every list route keeps returning a bare list; guard the backup path in
codex-mutate.js with the same assertNotSymlinkEscape the write path
already used (Claude's cc-mutate.js has no such guard on its primary
write path either, so left untouched there); relax readFileSafe's
containment to lexical-only, matching the other four Codex readers,
while leaving the write side's realpath check untouched; reuse
cc-plugin-cli's assertSource for marketplaceAdd instead of a third
validator (ssh remains out of scope, no credential story for it yet).
Server: 1557/1557 (was 1548). Client: tsc -b clean, 469/469 tests.
