Todo-list discipline

Red-team lab and interview checkpoint (Module 11, L11.3): how do you stop phantom completions in a multi-day agent? The validator reports 5 findings and leaves A6 clean. The honest path reports 0. Two in_progress items are a WARN and the handoff is not blocked. A1 is done with no evidence. A2 names work/gone.py, which is not on disk. A3 is in_progress 48 h against a 24 h heartbeat (NOW=1000). A4 duplicates id T4. A5 uses state almost_done. 168 lets A3 through. 0 flags a 1 h heartbeat. An empty file is not evidence, and that rule must not flag A6. In-memory only; injected clock; no threads or provider call.
