# Fixed-Wave Function Set — Separate Phase-1 Confirmation

**Status:** Separate 32-seed confirmation completed.  
**Pilot preservation:** PASS; all five Phase-0 artifact hashes were identical before and after this run.  
**Scope:** Fixed passive reciprocal temporal coupled-mode architecture; not energy gain, novel physics, material behavior, or hardware performance.

## Independent confirmation decisions

| Decision | Result |
|---|---:|
| Access badge | fail |
| Common-function process badge | PASS |
| Matched-coverage efficiency badge | fail |
| Phase + architecture-information mechanism | PASS |
| Access robustness (6/7 cases) | PASS |
| Numerical/passivity audit | PASS |

The structured controller reached **9/10** functions and the per-command
oracle composite of four frozen baselines reached **8/10**, a
confirmed difference of **+1**.

## Access across frozen plant cases

|---|---:|---:|---:|
| nominal | 9 | 8 | +1 |
| coupling_minus_5pct | 9 | 7 | +2 |

| intrinsic_loss_double | 9 | 8 | +1 |
| onsite_detuning_minus_5pct | 9 | 8 | +1 |
| onsite_detuning_plus_5pct | 9 | 8 | +1 |

## Mechanism controls

| Control | Structured successes | Control successes | Paired difference [95%] |
|---|---:|---:|---:|
| phase_scrambled_control | 314 | 0 | 314 [309.0, 318.0] |
| time_shuffled_control | 314 | 0 | 314 [309.0, 318.0] |
| wrong_model_inverse_control | 314 | 0 | 314 [310.0, 318.0] |

## Process and efficiency

On `8` shared reachable functions, structured coherent cross-talk was
`0.049` versus `0.134` for the
composite baseline, a `63.6%` reduction. Mean incident
energy was `0.250` versus `0.250`.
The cross-talk sign was positive in `7/7` plant cases.

Matched-coverage qProgT: **ratio 1.000, 95% interval 1.000–1.000**. Access, process, and efficiency remain independent.

## Numerical and artifact integrity

- Primary confirmation records: `12160` (expected 12,160).
- Half-step comparisons: `200` (expected 200).
- Label disagreements / closure failures: `0` /
  `0`.
- Maximum passivity residual: `2.426e-05`.
- Calibration manifest SHA-256: `48def9c56e46d2c11e175e8508ed0fcc427703b2d20fd45e1ff718c6ef2a8509`.
- Phase-0 pilot summary remains at `data/fixed_wave_function_pilot/pilot_summary.json`; it was not
  overwritten, pooled, or reclassified by this result.

## Interpretation boundary

The predeclared access-expansion claim is not promoted: the structured advantage
was +1 function, not the required +2. The confirmation does promote the narrower
common-function process result and its phase/model-information dependence inside
this fixed passive wave model. It cannot establish that no other controller
could match the result, that it transfers to hardware, or that any nonstandard
physics is involved.
