`status` could only answer running / starting / idle / killed / none, because every turn ran against `&NoopSink` and the whole stream-json stream was discarded. "Running" describes a wedged subagent exactly as well as a busy one, leaving a caller to tell them apart from `ps` output and CPU-time deltas. So the daemon now keeps a `name -> last_event_at` clock, bumped by `LivenessSink` on every line of every stream — stream-json events, plain stdout chatter and stderr alike — and `status` reports its age on a running answer: a few seconds means working, an age climbing into the minutes with no end-of-turn todo means wedged. Nothing is read out of the content; classifying *what* a subagent is doing is a separate question and waits on its own driver work. In memory with the rest of this daemon's state, dropped when the turn ends, no persistence. The clock is seeded at the spawn rather than at the first line, so a subagent that wedged before emitting anything still reports a climbing age rather than no age at all — the case an age is worth most in. Separately, `continue`'s existence pre-check is gone. It could only repeat the lookup `Claude::spawn` was about to do, and its message — "no session named `x` exists" — was false in the common failure: the session existed, just not under the claude home + cwd `build_store` resolved from. claude's own `--resume` is the authority and exits non-zero (`does not match any session title`) rather than quietly starting a fresh session, so the turn fails on its own. `classify_end` appends the one fact the CLI's message lacks — the directory searched: claude error: no session matched the requested id or title (searched <claude_home> for cwd <cwd>; if the session was started elsewhere, pass `dir`) The `dirs` map's durability is untouched; whether to persist it stays an open operator decision. Module doc, `docs/tools/subagent.md`, the `continue`/`status` tool descriptions and the `base:claude-subagents` skill all updated — including `continue`'s `dir` doc, which said "the daemon remembers it" without saying that a restart is both when it forgets and when you most want it.

hive-subagent-mcp
Per-agent daemon (hive-subagent-daemon) that spawns nested headless
claude sessions on request and serves the tool surface
(start/continue/interrupt) directly over streamable-http. No
stdio bridge, no per-turn respawn — claude reconnects to the same
stable URL every turn.
Independent of hive-bash-mcp — a subagent spawns a full nested
claude session, a much heavier capability than a bash command, worth
its own deployable/restartable unit.
Shape
One bin (hive-subagent-daemon, src/main.rs) built from the crate's
own lib (src/lib.rs):
session.rs— the actual claude-facing logic:Claude::spawn+RunningClaude::wait/cancel_handle(notInfiniteSession::run, which has no cancel handle to reach in — see the module doc for the v1 scope this trades away), the in-memoryrunningmap that's the only state this daemon keeps (no task files — a restart stops whatever's running; the actual claude session is the durable store, found again by name viahive_claude::SessionStore).mcp.rs— thermcptool router (start/continue/interrupt)serve_http.
paths.rs— the in-agent todo-socket path.
