Minimal reproducibility package

A positive interacting recovery claim should archive:

1. the frozen source array, source normalization, code, preparation, carrier ordering, bath cutoffs, couplings, and packet functions;

2. the regulator choice made before certificate evaluation;

3. the exact finite Hamiltonian specification and controlled propagator evaluation;

4. all logical matrix-unit outputs of both channels;

5. a rigorously feasible residual state or complete decoder;

6. validated positivity, trace-preservation, and trace-norm bounds;

7. arithmetic, collection, and implementation allowances at named interfaces;

8. the observation time or a proved uniform finite interval;

9. for a gravitational claim, the separate code, radiation, backreaction, geometry, and common-interval correspondence;

10. for an endpoint claim, the complete outgoing identification, bound/dark-sector audit, residual independence, and order of limits.

No item is replaced by a successful branch, population-only test, disorder-averaged channel, or selected entropy history.
