- hooks-config: a probe the bulk cap refused gets ONE bounded re-probe past the
cap (probeBeforeTouching), and whatever is still unknown is skipped. The
per-spawn hook and statusLine helpers used to fall back to an unbounded
lstat/readFile there, which on a dead workspace never settled and could take
the last threadpool workers (and hang the boot hook sweep). New test: cap
engaged, stat/lstat/readFile hanging on two more paths; both helpers return.
- describeUnknownPath()/unknownPathReason(): POST /api/sessions, quick-start and
GET /api/cases/:name now say a folder was not checked (other mounts are still
not answering) instead of blaming a healthy folder at the stall ceiling.
errorCodes unchanged.
- #535 x #516: Create in a custom folder probes the parent through the bounded
probe before realpath/stat/lstat/readdir touch it; an unknown parent is 422
OPERATION_FAILED (UNREACHABLE) within the probe timeout. New test.
- Docs: MAX_STALLED default is 2 (follows UV_THREADPOOL_SIZE), CaseInfo
.unreachable covers a refused probe, the boot sweep skips an unanswering
workspace, a CLAUDE.md gotcha for bounded probes, verbs.md documents the 422
(plugin mirror synced), api-reference documents the custom-folder 422.
- Tests: the launcher case-lookup describe is no longer nested in the Grok
block, and the cap-below-ceiling test no longer depends on an inherited
UV_THREADPOOL_SIZE / CODEMAN_PATH_PROBE_MAX_STALLED.
