 ## Unreleased
 
-### Added (0.74.0)
-
-- **Doctor findings deep-link to their page.** Summary tiles and
-  panel rows jump to where the finding is actioned: modules → store,
-  "approvals waiting for review" → approvals inbox, audit chain →
-  audit log (chevron affordance, tooltip + semantics button). The
-  host-services empty state gains a "view the configuration" button,
-  and the update banner's release-notes URL is a real link now.
-
-### Fixed (0.74.0)
-
-- **Runs page no longer contradicts the sidebar.** Load failures are
-  classified instead of all reading "hub not reachable": an older hub
-  without the ListInvocations RPC gets "this view needs a newer hub
-  version" with a doctor link, the detached-off refusal shows the
-  regular feature-off empty state, and unknown errors surface a
-  copyable detail box. "Not reachable" is reserved for genuine
-  connection failures.
-- **Audit page timer leak.** The live-stream reconnect timer is held
-  and cancelled on dispose.
-- **a11y suite flake killed at the root.** The pending-timer failures
-  came from the gRPC channel's 5-minute idle timer being armed when
-  the last stream closes; the suite now closes the channel and pumps
-  past the idle timeout (6 consecutive full runs green).
-
 ### Added
 
 - **Full-history audit export.** The audit page's actions menu gains
