I read this as an independent adversarial verification of Todo5 r9 - I will inspect the recorded transfer design and run only isolated local checks, then write the requested receipt if every required check passes.


I found a structural concern beyond the retained hook matrix: several resource factories return before their close callbacks are registered. I will run the mandated 40 hook cases, then probe those acquisition-to-registration handoffs directly in an isolated temporary process.


The retained 40-hook matrix passes, but the direct acquisition probes leak 1-6 descriptors at every unowned factory-to-registration boundary. I will still complete the specified local regression matrix to distinguish the transfer defect from unrelated regressions.


I read this as final Todo5 r9 adversarial verification - I completed local isolation checks and recorded the verdict.

NOT CONFIRMED.

- Retained 40-hook matrix passed; 1035/124/69/18/73/50 suites all passed.
- Independent line-trace injection found 24/24 FD leaks before callback registration:
  - pinned +2, authority FD +1, parent +1, authority +1, source +6, ledger +4.
  - Both `KeyboardInterrupt` and `SystemExit`, twice each; profile bytes unchanged and no adapter returned.
- Root cause: each factory result is briefly unowned before its `ExitStack` callback is registered.
