fix(core): drop native store write gate on HY search

MemHub expects concurrent native reads during precipitation. The
process-local read slot mostly existed for a Chroma/GIL fail-fast and
was never held by writers on main; activating it (as in #98) would only
push recall onto weaker fallbacks. Remove the lock module and the
hy_memory_store_busy path instead.

 ## Unreleased
 
+- 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.

+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.
