Terminals were a set of commands the platform drove. Officer sent pty:init / pty:input /
pty:resize / pty:close / pty:list over the registration socket, subscribed to ONE global
output stream, filtered every frame down to a session and rewrapped it — double
JSON-encoded — on the way out. That is terminal knowledge living in the process whose job
is authentication, and it made officer part of the data path for every keystroke.
The sidecar now serves its own loopback HTTP + WebSocket listener and announces the port
as `pty:server`, like every other HTTP sidecar. Officer authenticates the upgrade and
relays frames without reading them.
Split into three files, because "the sidecar" was one:
- sessions.mjs — the shell store. Spawn, attach, detach, resize, kill, scrollback, the
OSC-title scrape. Clients are a Set per session, so two panels can watch one shell.
- server.mjs — the listener. /ws speaks the browser's existing contract unchanged
({input,resize} in, {output,replay,exit,panel-refresh} out), plus /_officer/sessions,
DELETE /_officer/sessions/:id and POST /_officer/panel-refresh.
- index.mjs — the registration socket, and nothing else. It carries a port now.
On the platform side /api/terminal/* becomes createSidecarProxy, deleting the hand-rolled
router from two days ago, and websocket.ts drops from a translating bridge to a byte relay
modelled on the vault one. The whole PtyCommand/PtyEvent/PtyInitConfig/PtySessionInfo
vocabulary is gone from protocol.ts, connect.ts and sidecar-registry.ts.
broadcastPanelRefresh is now a POST to the sidecar: officer no longer holds terminal
sockets to loop over. Fire-and-forget — a missed refresh is a stale panel, not a failure.
The frontend did not move. The sidecar speaks what the browser already spoke.
The integration test was rewritten against the new shape, and tests something stronger than
before: officer is stopped mid-session and the shell keeps streaming, because officer is
not in the path at all. It also covers re-attach replay, the session list and kill.

it was the only sidecar living outside src/servers/sidecar/ — it sat in
api/terminal/ next to the bridge that talks to it, which is the one place a reader
looking for "the sidecars" would not check. now src/servers/sidecar/pty/index.mjs,
matching every peer, with a note on the pm2 entry about why this one is node and
.mjs (node-pty is a native addon) rather than bun and typescript like the rest.
the templates/ directory went to api/users/, next to provision.ts:seedShellConfigs,
which is now its only consumer — the sidecar's duplicate seeder went with the
sandbox branch in the previous commit. api/terminal/ is left holding exactly one
thing: the websocket bridge.
no behaviour change. the pm2 entry's script path changed, so `pm2 restart
officer-pty` is not enough — pm2 remembers the old path until the entry is deleted
and started again. commands are in SIDECAR_WORK_LOG.md.
