+`max_runtime` starts when Hub dispatches the step. Preparing a filesystem worktree, creating the provider agent, restoring a continuation workspace, and acknowledging the initial prompt all consume that budget. The deadline does not reset when startup finishes or activity arrives. The trigger's whole-run deadline can end the step sooner. Provider-specific startup failures can also end a step before its deadline.
+
+`idle_timeout` starts alongside dispatch. An `initializing` or `running` agent status clears the idle deadline; an `idle` status starts it again. Meaningful agent activity refreshes an armed idle deadline. Connection heartbeats do not count as agent activity. Allow enough idle time for preparation before the daemon reports an active agent.
+
+Continuation requires a daemon that supports cancelable agent requests. Update the daemon if Hub requests an update. When a deadline expires, Hub ends the step and reconciles daemon cleanup before another step can use the same conversation. If a daemon restart leaves the operation's outcome unknown, inspect the agent and workspace in Paseo before retrying with a new conversation key; Hub does not automatically repeat an ambiguous launch or prompt.

-## Startup timeout
-
-Hub waits up to **two minutes** for agent startup, including worktree creation, provider startup, and initial prompt acceptance. For a slower machine, set `run.startup_timeout` in the trigger YAML:
-
-```yaml
-name: inspect
-on:
-  manual.run: {}
-run:
-  target: { daemon: devbox, cwd: /workspace/project }
-  agent: { provider: codex, mode: full-access }
-  startup_timeout: 5m
-  prompt: Inspect this repository and summarize its current state.
-```
-
-Use a positive duration in `ms`, `s`, `m`, or `h`, up to `24h`. Omitting the field uses `2m`. The existing `max_runtime` and `idle_timeout` limits still apply during startup and can expire sooner. This setting changes Hub's waiting budget; provider-specific timeouts remain in effect.

 If Hub loses the create response, or the daemon restarts mid-execution, Hub resends the same create intent with the same execution id. The daemon returns the existing agent rather than running the prompt again. An agent that closed or errored is recorded as interrupted; Hub never silently starts a second one.

-Restarting Hub preserves active executions and their existing credentials. Hub reconnects to the same agent and restores the original credential deadlines. A restart does not mint a replacement token or extend its lifetime.

-If Hub is unavailable when a shorter duration elapses, it revokes the overdue token when it returns. GitHub’s own expiry still limits the token lifetime to one hour. Revocation failures are retried after recovery.

-Hub persists resolved values as private execution data so it can recover after a restart. Authored configuration retains the expressions.

-These values are stored in the Hub database without application-level encryption. Protect database access, storage, and backups as credentials. Hub deletes the execution authority record when the execution becomes terminal; token lease records remain until revocation succeeds or the token expires, so interrupted cleanup can resume. This cleanup is not a guarantee that every copy is erased: retained agent/session data and database backups may still contain resolved values. Token revocation ends access; it does not erase those copies. Backup retention and deletion remain the operator’s responsibility.
