 ## Adds
 - Added `docs/plan/v0.1.41-milestone.md` to define scope and acceptance criteria.
+- Added `docs/specs/remote-tmux-ssh-discovery.md` as a future backlog spec for opt-in remote tmux discovery over SSH.
 
 ## Changes
-- TBD: summarize runtime signal refinements merged during v0.1.41.
+- Clarified fleet heartbeat metrics with explicit progress status (`progressing|stalled`) and a clearer cadence field (`window`).
 
 ## Fixes
-- TBD: summarize cadence and control-path regression fixes merged during v0.1.41.
+- Added cadence edge-case tests for future timestamps to avoid false-positive heartbeat emission.
+- Added minimum-interval heartbeat tests for zero-poll inputs to keep cadence behavior deterministic.
 
 ## Validation
 - `cargo fmt --check`
