 - **2026-10-13 DB-less freshness #721 and authorization remarks #722 resolved (PR #724, master `c89912a9`).** Required hosted run986 passed at final `c4b40468`: all ten steps, 62 TRX files, 14,656 executed tests, 573 skips, the 12,000-test floor and finalized artifacts. Merged tree `973c6799` equals the tested head. Runtime837 passed/three existing skips; missing-local-entry zero/retry/recovery and absent-snapshot timer controls passed, and guard/timer mutations failed. Main checkout fast-forwarded with seven currently visible user-owned files byte-preserved; three ignored local support files still match prior preserved hashes. No live calls, deployment or Warm policy changes.
   - **Test cleanup #725/#726:** reviewed offline cleanup/discard fixes published in PR #730 at `4f537a56` after integrating merged main. Six affected driver suites passed3,323 tests; helper exception policies and cleanup-removal regressions verified. Final-head hosted CI and merge remain pending; #726 stays open and #725 covers remaining warnings.
   - **New follow-ups:** #727 records an additional Modbus cache-reset fixture failure-cleanup gap; #728 records the unchanged ConditionRefresh intermittent failure (local fail/pass/fail and superseded CI985 failure; CI986 passed); #729 records source-only mutable CTS delegate capture with no claimed observed runtime failure. None is resolved. Warm #717 architecture/policy gates remain open.

+- **2026-10-13 driver fixture cleanup #726 resolved (PR #730, master `ebcbd81f`).** Required final-head run988 passed all ten steps on `4f537a56`:62TRX reports,14,672executed tests,573individual skips,12,000-test floor and finalized artifacts. All six affected suites passed3,323/0failed/0skipped; helper exception policies and cleanup-removal regressions were independently verified. One linked test helper guarantees shutdown through initialization/assertion failures while preserving the primary exception and reporting secondary cleanup faults; all original assertions/settings/tokens/deadlines remain. Modbus evidence covers cancellation/disposal/request completion, not joining discarded probe tasks. Five Task-valued assertion discards are also merged with no hosted CS4014 emissions; #725 remains open for other warning groups. Merged tree `189a116a` equals tested tree; main checkout fast-forwarded with ten user-owned file hashes freshly preserved. No production changes or live calls. #727/#728/#729 remain open; no pass supplies their missing cause/probe evidence. Automatic merged-main run989 is observed separately.
