v0.6.5 Announcement

English

Agent Memory Bridge v0.6.5 is out.

This release tightens signal coordination by making generic claim selection fairer under contention.

What changed:

1. Claim selection is now fairer

• when signal_id is omitted, claim_signal(...) selects from the oldest eligible window
• it avoids immediately favoring the same consumer's stale claim when other pending work exists
• this reduces accidental poll-order wins without expanding the MCP surface

1. The fairness contract is now tested

• deterministic proof now checks the stale-reclaim fairness case
• signal lifecycle remains claim -> extend -> ack / expire / reclaim
• full suite remains green

1. Learning-quality work stays intact

• slice-aware classifier calibration remains in place
• benchmarked retrieval still holds on the canonical fixture

Current state:

• no MCP surface break
• fairer generic claim behavior
• 80 passed

简体中文

Agent Memory Bridge v0.6.5 发布了。

这次发布主要把 signal coordination 再收紧了一步：让泛化的 claim selection 在竞争场景下更公平。

主要变化：

1. claim selection 现在更公平了

• 当 signal_id 留空时，claim_signal(...) 会从最老的 eligible window 里选择
• 如果还有其他 pending work，同一个 consumer 不会优先把自己刚过期的 stale claim 又捡回去
• 这样能减少纯轮询顺序带来的偶然优势，而且不需要扩 MCP surface

1. 这条 fairness contract 现在有测试保护

• deterministic proof 现在会检查 stale-reclaim fairness case
• signal lifecycle 仍然是 claim -> extend -> ack / expire / reclaim
• 全量测试继续保持绿色

1. learning-quality 这条线保持不变

• slice-aware classifier calibration 继续保留
• canonical fixture 上的 benchmarked retrieval 也还在

当前状态：

• 没有 MCP surface break
• generic claim 行为更公平
• 80 passed
