setBroadcast() on an unbound dgram socket throws EBADF on Linux and the following
send fails with EACCES, so the magic packet silently never left the machine — the
feature reported a wake that never happened. Caught by waking a real sleeping host
(a unit test with a real UDP broadcast would not be welcome in CI, so the socket is
injectable and the bind-before-setBroadcast ORDER is asserted).
The reactive wake (typing into a session whose host slept) left the state invisible:
nothing told the user the machine was asleep, and with no wake target configured
there was nothing to do about it. Adds:
- RemoteHost.wakeMac (comma-separated) - Codeman builds and broadcasts the magic
packet itself (UDP port 9), so the common case needs no external script. The
existing wakeCommand stays as the explicit override.
- GET /api/sessions/:id/reachability - probes (throttled, cached, and it never
wakes) and reports HOW the host can be woken, or that nothing is configured.
- POST /api/sessions/:id/wake - wakes, waits, reattaches the pane and flushes
buffered input; 400 with a routable message when no target is configured.
- The amber host-unreachable banner + its 'Wake' / 'Configure WoL' action, and a
small config dialog that saves via PUT /api/remote-hosts/:id.
- RemoteWakeDeps.resolveRemote: host config is re-resolved for LIVE sessions
(throttled + cached), so saving the dialog takes effect without a restart.
Self-review pass: the input-ladder's two 'buffer' branches were the same three
lines, and bulk delete left a session's (bounded, per-random-uuid) wake state
behind. Documents the design where the code refers to it - remote-sessions.md
section, the architecture invariant, and the CLAUDE.md key pattern.
A session's remote block is persisted at launch time and recovery uses that
snapshot, so a wakeCommand added to remote-hosts.json afterwards never reached
an already-running session - not even across a Codeman restart (observed: the
live Hufflepuff session came back with no wakeCommand). Merge the host-level
field in on restore, with the host config authoritative.
A durable remote session survives SSH drops (COD-104/108), but nothing brought
the HOST back: after the remote machine suspended, the local tmux pane's ssh
child stalled silently and `send-keys` SUCCEEDS against it, so typed input
vanished with no error anywhere.
Add an optional per-host `wakeCommand` (Wake-on-LAN wrapper, e.g. whuff) that
the input route runs when a wake-enabled host is unreachable: input is buffered,
the host is woken, the pane is reattached, and the buffer is flushed in order.
Detection is a throttled bare TCP probe on wake-enabled hosts only, and only
REAL user input may wake a host - the auto-reconnect watcher and boot recovery
deliberately cannot, or the host would be re-woken seconds after every suspend
and could never stay asleep.
A clicked path that points OUTSIDE the case directory goes through the attachment
routes (the frontend's `_isExternalPreviewPath` sends every absolute path not under
`workingDir` to `POST /attachments`), and those had the same local-`fs` assumption
as file-raw: `realpathSync`/`fs.stat` on a path that only exists on the remote host,
so the file never opened — the case the #415 report was actually about.
- `registerExternalAttachment()` accepts `remote` and resolves through
`remoteProbePaths` (canonical path, size/mtime, kind, plus the workspace root for
the confinement check). Everything around it — blocklist, extension allowlist,
workspace confinement, registry/dedupe — is now shared by both branches, so the
remote path cannot drift from the local one.
- The by-id routes (`raw`, `preview`, `thumbnail`), the metadata poll and the
attachment history list resolve over ssh too. `raw` streams with the same
Range contract as file-raw; `preview` (office) and `thumbnail` answer 400 for a
remote record; an unreachable host answers 502, a vanished file 404.
- Which host a record is read from follows the SESSION, never the path string: the
same absolute path is a different file on each host, and a remote session never
falls back to a local file with that name.
- Codex generated artifacts keep force-workspace confinement for a remote case: the
well-known artifact directories are anchored at THIS host's home, so only a file
inside the remote workspace is trusted.
Still local-only by design: writes, office conversion, thumbnails, the file
tree/picker and tail-file.
A remote case's workingDir is an absolute path on the remote host, but the
file read routes resolved it with local `fs`: `validateSessionFilePath`'s
realpathSync fails for a path that does not exist on the Codeman host, so
every preview of an agent-written file answered "File not found" (#415).
Add src/remote-files.ts as the single remote-read layer, built on the same
buildSshConnectionArgs() the launch uses:
- remoteProbePaths(): ONE round trip returning realpath + stat for the
requested path AND the workspace root, so containment is checked against a
remotely canonicalized root (a symlinked remotePath is ordinary).
- remoteCreateReadStream(): streams the body (cat, or tail -c +N | head -c L
for a Range) with nothing buffered in memory, and reaps the ssh child when
the response ends so an aborted download cannot orphan it.
- remoteReadFile(): bounded read for file-content.
file-raw, file-content, file-preview and file-thumbnail now share one local/
remote target resolution. Guards keep their local strength: lexical pre-check,
remote realpath, workspace containment, sensitive-path blocklist, and the size
cap applied to the remote size before any bytes are read. An unreachable host
answers 502 with the remote reason instead of a misleading 404. Nothing is ever
copied to the Codeman host and there is NO local fallback (an sshfs mount of
the same tree must not shadow the remote bytes).
Deliberately unchanged: writes (edit=1 / PUT now answer 400 explicitly while
the viewer hides its Edit affordance), office previews, thumbnails, file tree,
picker, external attachment registration and tail-file stay local-only.
