HEL-906: close r5-followup-package §4 blocker, register milestone, add handoff
- §4: ASR audio/retry rows now program-gated (pre-send/pre-connect refusal
when armed, fail-closed default); mechanism, arming env, reproducible
verification commands, program-guarantee vs monitor-only boundary
(bounded cross-process staleness, bounded crash undercount, .12 real-stack
pre-window check still required); wall-clock proxy demoted to lower-bound
cross-check; first-line status updated
- milestone table: register hel-906-asr-usage-counting @ ecec9df (candidate,
PR not merged, pending 总管 review)
- handoff-HEL-906.json (v1.12, read at 0b804a4); requirement checks 4/4 pass
(origin/main and 0b804a4, with/without handoff)
