github-devloop Rollup

Repository: ChronoAIProject/talos
Upstream: qa-tools
Integration branch: qa-tools-fkst-staging
Immutable integration head: a7fc21d421102d4c1a367c650d479cd690752af3
Ahead commits: 6
Included work: #42 via PR #43

Highlights

• Binds terminal interactive-action retries to immutable, server-authored dispatch credentials instead of mutable Task ownership.
• Adds monotonic dispatch generations and repository-level compare-and-set fencing for dispatch, terminalization, requeue, reclaim, expiry, and teardown races.
• Preserves the first terminal winner and its dispatch binding, allowing correctly bound retries to converge on 409 action_already_completed while stale or invalid bindings receive a uniform 401.
• Enforces credential-carrier consistency and validation ordering to reduce task/action existence disclosure.
• Adds bounded, restart-safe Mongo quarantine for unsafe legacy in-flight actions, including interrupted-migration recovery coverage.
• Expands Memory/Mongo repository and HTTP contract coverage for redispatch, lifecycle transitions, winner immutability, malformed bindings, route normalization, and legacy records.
• Removes fixed-by-construction Browser execution counters; tests now assert authoritative persisted repository outcomes without claiming Browser exactly-once execution.

Status

PR #43 completed eight review/fix rounds, received unanimous approval, passed its pre-merge CI gate, and was merged into qa-tools-fkst-staging. This rollup records staging integration only; it does not represent delivery to qa-tools.

中文摘要

• 终态操作重试改为绑定不可变的派发凭据与递增代次，不再依赖可变 Task 租约。
• 通过仓储级 CAS 保证首个终态结果胜出，并统一处理过期、重派发、回收与关闭竞态。
• 增加旧版 Mongo 在途操作的分批隔离及中断后恢复验证。
• 补充 Memory/Mongo 与 HTTP 契约测试，并移除无法证明浏览器仅执行一次的代理计数断言。
• 当前内容仅合入 qa-tools-fkst-staging，尚未交付到 qa-tools。
