chore(release): bump MemHub build number to 26

fix(memhub): search on submit and set SDK recall limits apart

 ## Unreleased
 
+- The SDK memory page now reads its list, count, source and time labels and
+  graph from one page response for one source filter, so rows, totals and the
+  map no longer disagree. Memories with no recorded source are shown and
+  filterable as "unidentified source"; library search keeps only memories
+  that contain the words within the SDK's relevance window.
+- Metadata repair v2 follows `governed_memory_evidence` across every
+  pre-cutover bundle, which restores the source of memories the cutover
+  backfilled without one, and moves impossible future conversation times back
+  to the write time.
+- Reused the existing three-column memory map for SDK-authority list/detail
+  views and removed the retired "original evidence" surface. SDK-native status,
+  source, conversation time and creation time now render without fabricated
+  revisions; source and text filters are applied by the paged Core endpoint.
+- SDK memory search now calls the SDK search contract instead of listing the
+  entire library in Core. Corrupt empty records are skipped and diagnosed
+  without mutating data or failing a page, and post-cutover metadata repair
+  restores source and original times from the verified migration bundle.
+- Kept Cursor's WAL change token separate from the file mtime so a hash can no
+  longer appear as a conversation date centuries in the future.
+- A trusted packaged Runtime now repairs a dirty same-build installation by
+  staging a clean replacement, and `runtime_service_not_ready` is rendered as
+  user-facing startup guidance instead of an internal code.
 - Fixed legacy-to-SDK startup migration to adopt native Coding Experience and
   Working Fact IDs instead of importing them as Chat layers. Raw migration now
   rebuilds bounded user/assistant turns from the latest three days, excludes
