The paste-image route wrote under session.workingDir via ensureUploadDir
with no bounded probe, so an upload onto a stalled network mount held one
of libuv's few threadpool workers until the mount answered. Probe the
workspace with probePathKind past the stall cap before the first disk
touch and refuse an unknown mount through describeUnknownPath, the way
POST /api/sessions already does.
The bounded path probe answered "absent" both when a path did not exist and
when it simply did not answer, so a stalled linked case 404'd and the Run
button scaffolded a stray local case over it, and two stalled paths anywhere
made every unrelated path read as absent (hooks skipped, statusLine
overridden, the clone warning lost).
- probePath()/probePathKind() are tri-state: present (or directory/file),
absent (ENOENT/ENOTDIR only) and unknown (timeout, other errors, refusal).
boundedPathExists() stays as the display-only boolean.
- A stalled path takes only its own mount out of probing (deepest mount
point from /proc/self/mounts, never /; just the path itself when there is
no mount table). Unrelated paths keep probing. The process-wide cap is a
backstop that answers unknown, and a single-path user request can probe
past it ({ pastCap: true }), still bounded and still recorded as stalled.
One console.warn when a path first stalls and one when the cap engages.
- GET /api/cases/:name keeps NOT_FOUND for definite absence only. An
unreachable linked case answers with its registered path and
unreachable: true; a local one answers OPERATION_FAILED. runClaude and
runShell create a case only on errorCode NOT_FOUND. The case list keeps an
unreachable linked case, marked unreachable, instead of dropping it, and
fix-plan reports an unreadable plan as an error, not "no plan".
- applyWorkspaceHooks and the statusLine helpers skip only a workspace that
is absent or on the stalled mount; a capacity refusal no longer stops
hooks being installed elsewhere, and an unreadable settings file never
lets the exporter override a user's own statusLine.
- The clone flow's repo-settings warning is back on its synchronous check,
and stripCaseEnvKeys uses pathExistsForWrite.
- POST /api/sessions (workingDir) and POST /api/quick-start (case folder)
probe with the bounded probe instead of statSync/existsSync. Missing and
non-directory keep INVALID_INPUT; unknown is OPERATION_FAILED, and
quick-start never scaffolds over a folder that did not answer.
- PATH_PROBE_TIMEOUT_MS and MAX_STALLED_PATH_PROBES move to
src/config/path-probe.ts, overridable via CODEMAN_PATH_PROBE_TIMEOUT_MS
(default 1500) and CODEMAN_PATH_PROBE_MAX_STALLED (default 3), and are
documented in the Settings Reference.
- The probe is exported from the utils barrel and imported from there.
