 Hy Memory and MemHub are versioned and released independently.
 
-## Unreleased
-
-- MemHub "添加记忆" (add a memory) no longer waits behind unprocessed history.
-  Notes are claimed ahead of the event-time window that keeps history strictly
-  old to new; they still run one at a time and in order within their session.
-- SDK reconcile keeps time order. Both reconcile prompts now state that only
-  `memory_at` decides which memory is newer, that an older memory must never
-  supersede or overwrite a newer one, and that an unknown time is not newer;
-  the Chinese prompt now lists `memory_at` among the new-memory fields. The
-  reconciler also enforces this in code: a SUPERSEDE or UPDATE aimed at a memory
-  with a later `memory_at` becomes an ADD, so the newer memory stays current.
-- 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
-  tools, and enforces the same rolling retention after cutover.
-- Paused host capture writes with a live Desktop migration fence; Cursor
-  History catch-up resumes from its existing checkpoint after cutover.
-- Removed MemHub's private `hy_memory_bridge` implementation. MemHub now calls
-  public `HyMemoryClient` methods at runtime; prompt/reconcile/response
-  monkey-patches and private VDB/Coding runtime access were deleted. Kuzu Graph
-  projection/admin and stopped-writer App migration are the documented product
-  exceptions.
-- Added a MemHub-managed native Hermes MemoryProvider with automatic prefetch,
-  persistent per-session memory-ID deduplication, authorized Broker reads, and
-  recall-context stripping to prevent memory recursion.
-- Added an extensible MemHub interface-localization layer with Simplified
-  Chinese, English, and Spanish catalogs shared by Web and Electron-native
-  surfaces. Interface language remains independent from memory content and
-  model processing language.
-- 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.
-- 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.
-- 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.
-- Existing installations ignore the retired config flag, readmit previously
-  parked pre-invocation work, and drop only the obsolete
-  `hy_node_permissions` proof table. Evidence, governed memories, model
-  profiles, SDK stores, and source/host grants are preserved.

-
-- Published
-  [`hy-memory==2.0.5`](https://pypi.org/project/hy-memory/2.0.5/).
-- Extended `get()` across Chat, Coding Experience, Working Fact, and raw IDs;
-  the returned `layer`, `kind`, and `variant` identify the actual record.
-- Added explicit raw retrieval through the existing `search()` and
-  `list_memories()` contracts, including user, agent, session, and source
-  filters.
-- Added public embedding-service injection and corrected extraction language
-  detection for structured OpenAI-style messages.
-- Added lifecycle status filters, durable idempotent write outcomes, and
-  quiesced local data-plane snapshot/restore.
-- Kept legacy migration mechanics out of the public Client API; separate
-  migration-only raw/import methods from development previews were removed.
-- Physical delete now reports partial VDB/Graph cleanup as failure.
-- Coding search no longer injects the version-evolution diff block by default;
-  opt in with `MEMORY_CODING_CHAIN_BLOCK_ENABLED=true`.
-- Serialized SDK SQLite cache/history connection lifecycle and tightened
-  Coding reconciliation to its agent/session/workspace authority.
-- Clarified persistent caller context through `meta`, while `metadata` remains
-  legacy processing configuration.

+## Unreleased
+
+- Added a MemHub-managed native Hermes MemoryProvider with automatic prefetch,
+  persistent per-session memory-ID deduplication, authorized Broker reads, and
+  recall-context stripping to prevent memory recursion.
+- Added an extensible MemHub interface-localization layer with Simplified
+  Chinese, English, and Spanish catalogs shared by Web and Electron-native
+  surfaces. Interface language remains independent from memory content and
+  model processing language.
+- `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.
+- Existing installations ignore the retired config flag, readmit previously

+"""A0-03: measured answer to "can a HY write be made idempotent?".
+
+The result decides whether the `unknown` job state can ever be retired, so it
+is probed against the installed SDK rather than written down from memory.
+
+What is verified against `hy-memory==2.0.5.dev3`:
+
+- `HyMemoryClient.add(..., request_id=...)` accepts a caller-supplied id and
+  atomically claims it in the SDK cache before invoking a write. Replays return
+  the durable terminal result; running/unknown claims are not invoked again.
+- `HyMemoryClient.get_write_outcome(request_id)` reads that durable outcome
+  directly; it does not depend on optional pipeline tracing.
+
+A first pass at this probe got both answers wrong, and the failure mode is
+worth keeping in mind: searching SDK source for the string "idempotent" hits a
+docstring about *episode* nodes ("calls are idempotent") and a "dedup" comment
+about search over-sampling. Neither is write idempotency. So the probe checks
+the `add` path specifically and names the inspector class explicitly, instead
+of grepping for a word that appears in unrelated prose.
+
+Net: MemHub can query and settle an uncertain request without blind replay.
+`unknown` remains a legitimate operational state while the SDK claim itself is
+non-terminal, but the same request id cannot write twice.
