 ### Fixed
+- `whoami` and `help("timers")` now advertise the full Solo-parity timer
+  surface (`timer_set`, `timer_fire_when_idle_any`,
+  `timer_fire_when_idle_all`, `timer_cancel`, `timer_pause`,
+  `timer_resume`, `timer_list`) so agents using either tool for
+  orientation discover them — previously only `timer_wait` was listed.
+- Resuming a paused idle-aware timer now re-checks the satisfaction
+  condition. Previously, if every watched process became idle (or, for
+  `idle_any`, any non-baseline watcher went idle) while the timer was
+  paused, the timer stayed pending forever because no further state
+  transitions were observed.
+- Fired and canceled timers are now removed from the timer registry,
+  so long-running patterm sessions no longer accumulate completed
+  timer records and message bodies. `timer_list` and the sidebar
+  indicator already filtered them out; only the in-memory leak is
+  fixed.
+- Per-preset idle-detection config is now installed through `SpawnSpec`
+  before the child is published to the session, closing a race in
+  which the classifier goroutine could observe a freshly spawned
+  process before its preset's classifier strategy was attached.
