 ## 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,

+2. POST this exact JSON to \`http://HOST:PORT/pair\` with \`Content-Type: application/json\`:
+
+\`\`\`json
+{"code":"${pairing.pairingCode}"}
+\`\`\`
+
+3. The successful response contains \`credential\`. Save only that value, followed by a newline, in a new private local file owned by the current user. On POSIX systems set the file mode to \`0600\`. Never print, quote, log, or place the credential in chat, Skill text, shell history, source control, or the MCP JSON itself.
+4. Replace the placeholder below with that credential file's absolute path, then merge this MCP server into this Harness's local MCP configuration while preserving all other servers:
+
+\`\`\`json
+${JSON.stringify(mcp, null, 2)}
+\`\`\`
+
+5. Restart or reload this Harness's MCP services if required. Run one real MemHub recall query and report whether the tool was discovered and the authenticated query succeeded. Do not report success merely because files were written.
+
+The pairing code is single-use. If pairing fails or the code has expired, stop and ask the user to generate a new Skill in MemHub. Do not guess codes, reuse another Harness's credential, disable authorization, or broaden permissions.
