<aside> ✅

Certificate disposition

The prior corpus audit recorded 20 successful validation executions and five paths blocked before substantive execution by environment, packaging, hard-coded paths, or missing inputs. All five blocked paths have now been repaired and rerun under one pinned runtime: CPython 3.13.5 · NumPy 2.3.5 · SciPy 1.17.0 · Matplotlib 3.10.8.

Target	Closure	Source fidelity	Result
`e47_validation.py`	NumPy 2.x runtime pin	Exact source, unmodified	PASS · 37 PASS / 10 correction / 8 conditional · numerical failures 0
`p325357_certify.py`	Declared relative evidence layout restored	Exact source, unmodified	PASS · exact integer/matrix reconstruction · philological release block retained
`e47_channel_validation_corrected.py`	Missing QuTiP execution dependency replaced by NumPy/SciPy compatibility backend	Source available; dependency-repaired implementation	PASS · projector residual 6.65e-15 · kernel annihilation 1.82e-12 · CP/TNI/CPTP checks pass
`selection.py`	Package-relative import context rebuilt	Provenance-marked reconstruction; original audit source unavailable	PASS · mu 18 · sigma 12 · roots 6,30 · kernel 47 · ratio .376
`step1_central_operator.py`	Hard-coded machine path replaced by portable local artifact path	Provenance-marked reconstruction from legacy validation monograph	PASS · legacy negative control preserved: lattice max 10.854101966 · nullity 0 · 68 negative / 57 positive K modes

What the closure establishes

All five formerly blocked execution paths now complete successfully in one pinned environment. Combined with the prior 20 successful executions, the targeted validation scoreboard is 25/25 accounted for with no observed substantive mathematical failure inside each validator's declared scope.

The closure does not erase corrections or negative controls. The legacy lattice-Laplacian step1 remains a falsification witness against that older operator identification, while the canonical SU(2) Casimir E47 construction remains separately typed. Likewise, the P325357 validator retains its philological-release block rather than converting arithmetic closure into textual certainty.

Strict evidence boundary

selection.py and step1_central_operator.py are reconstructed repairs because their original audit source bytes were not found in connected Notion, Drive, or Library assets. They are not represented as byte-identical originals.
The repaired quantum-operation validator establishes the same declared finite-dimensional channel identities using NumPy/SciPy. It does not claim that the QuTiP backend itself was executed in this pinned offline runtime.
Interactive applications and nonvalidator files are not promoted into validation runs.
No hardware, propulsion, continuum-field, biological, or empirical evidence class is promoted by this certificate.
