v0.16.0 - Reviewed Memory Operations Queue

Agent Memory Bridge 0.16.0 is a narrow operator-workflow release over the
governed learning-candidate and memory-evolution lanes. It keeps the public MCP
surface stable while making review work easier to see and audit.

0.16.0 = read-only reviewed memory operations without autonomous mutation.

What Changed

• Added agent-memory-bridge review-queue, a CLI/report for operator review
  over staged candidates, learning reviews, tombstones, stale/expired records,
  and quarantined claims.
• Review-queue items carry a proposal_only_no_auto_mutation writeback plan so
  operators can see the next safe action without AMB executing it.
• Added a deterministic review-queue benchmark snapshot at
  benchmark/latest-review-queue-report.json.
• The release contract now checks the review-queue snapshot facts alongside the
  retrieval, calibration, procedure, signal-contention, adversarial, and
  memory-evolution snapshots.
• The public MCP surface remains unchanged at 10 tools.

Public Surface

The public MCP surface remains unchanged:

• store
• recall
• browse
• stats
• forget
• promote
• export
• claim_signal
• extend_signal_lease
• ack_signal

There are no new review_queue, review_candidate, learning_candidate,
startup_packet, task_packet, evolve_memory, graph, scheduler, or runtime
MCP tools in this release.

Honest Boundary

This release does not claim:

• autonomous review or promotion
• automatic durable writeback from raw transcripts
• automatic deletion or tombstone enforcement
• a review UI
• a graph database or graph-memory platform
• ACL enforcement, privacy compliance, or certified poisoning resistance
• a scheduler, worker runtime, queue platform, or distributed lock

It adds a local, repeatable proof path for seeing review work before it becomes
authority.
