+- Development preview; not the final `2.0.5` release.
+- Published as

+- Adds exact, idempotent semantic-memory import for legacy MemHub cutover

 ## Unreleased

+- `search(..., layers=["l1_raw"])` now explicitly searches SDK raw records in
+  pro/ultra mode and keeps existing user/agent/session/source filters; default
+  search continues to hide raw.
+- Added `import_memory_exact` for idempotent migration of an existing semantic
+  memory with its canonical ID, lifecycle and supersession links, without
+  extraction or reconciliation.
+- Added SDK-authoritative lifecycle listing with explicit status filters,
+  idempotent durable write outcomes, exact raw import/get/list APIs, and
+  quiesced local data-plane snapshot/restore contracts for the MemHub
+  authority migration.
+- Physical delete now reports incomplete VDB/Graph cleanup as a partial failure
+  instead of claiming success after only one store was changed.
+- Coding search no longer injects the version-evolution diff block
+  (`chain_block`) by default. Enable with
+  `MEMORY_CODING_CHAIN_BLOCK_ENABLED=true` or
+  `CodingConfig.chain_block_enabled=True` (write-side observe unchanged).
+- Fixed governed-memory revisions and repeated evidence links failing when the
+  visibility dirty-marker trigger encounters the same memory twice. Startup
+  now replaces the affected legacy trigger without changing schema versions
+  or governed and visibility data.
+- Serialized each SDK SQLite store's shared connection lifecycle so concurrent
+  history/cache operations cannot race with `close()` and crash the process.
+- Scoped Coding reconciliation targets to the current HY authority,
+  conversation, and workspace, preventing near-duplicate sessions from
+  mutating an experience or working fact owned by another evidence context.
+- Kept post-write authority verification failures available for read-only
+  reconciliation while preventing automatic or generic confirmed retries from
+  invoking the model again. Automatic reconciliation skips those sticky rows
+  before applying its batch limit, and linked durable jobs exclusively own
+  retry scheduling for their memory tasks.
+- Clarified that `add(metadata=...)` carries legacy SDK processing options,
+  while persistent caller business context belongs in `meta`.
+- Added an opt-in `get(..., include_raw=True)` path for reading `L1_RAW`
+  memories, including memories written in lite mode. The default remains
+  hidden for backward compatibility.
 - Removed MemHub's task-scoped HyPermission store wrappers and global
  model-content consent switch. The trusted embedded Hy Memory SDK now uses
  its native local stores directly.
