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.

# @description Server mode, one Linux user per account (S3): installed as
|
|
# /opt/agenthub/libexec/write-as. The dashboard runs it AS a member through
|
|
# sudo (`sudo -n -u ah-<name> /opt/agenthub/libexec/write-as <path> [mode]`)
|
|
# for every change it makes inside that member's home — the file editor, a
|
|
# `.gitignore` line, the files a pane reads (prompt, proxy settings, context
|
|
# copies, drops, a session's launch file) — because the dashboard itself may
|
|
# never write, chmod or delete there: the member can swap any name in their
|
|
# own home, and a write by another account would follow the swap. As the
|
|
# member this can only do what the member could. Content comes on stdin,
|
|
# never in argv (sudo logs argv). Modes:
|
|
# (none) stdin into the file in place (keeps its mode and owner)
|
|
# append stdin appended
|
|
# replace stdin into a new 0644 file renamed over the path (atomic)
|
|
# private same, 0600
|
|
# mkdir the directory, 0755, parents included
|
|
# remove the path, recursively (rm never follows a symlink it removes)
