- settings.agent.autoInvestigateMode investigate|recover, investigateMaxAttempts, recoverVerifySec
- new capability download.recheck (execute, replay never): qB force recheck / resume, no source swap/delete
- autoInvestigate moves to agent/investigate.ts: recover mode runs execute with a recovery allowlist
only when an active grant (published policy if bound) covers the recovery actions; otherwise degrades
to read-only investigation and leaves suggestion + recheck option on the decision
- runAgent verifies recovery against business facts (download_task/task/source_release) before finalize;
verified -> decision resolved by system:auto-recover, run summary '已恢复(系统核实)'; otherwise stays
awaiting_user; per-root-cause attempt cap
- e2e E6: missingFiles -> download_failed -> recheck -> verified; no grant degrades; swap rejected;
dedupe; attempts exhausted; budget exceeded keeps attention
