# AP1-R2c validated alternative p41 PASS

Timestamp: `2026-09-02T10:48:40Z`

Starting only from the validated p40 PASS, the bounded parameter tuple
`beta=2.2`, background `alpha=-8e-6`, and partial `rho_chi`
`alpha=4.25e-5` produces a second full p41 PASS.

Three independent checks agree:

- DAE: `9.246057492761888e-5`
- Ward: `9.780233224098215e-8`
- source closure: `8.490743793048986e-5`
- Friedmann: `1.512769178580952e-16`
- Wronskian: `1.26e-49`
- minimum `H`: `8.31258710425034e-8`
- minimum `P_X`: `1.8132335484729594`
- minimum `K`: `3.016188545394498`

This valid branch is not selected as the authoritative continuation parent.
Its nine-candidate p42 child bank reaches only
`6.212973026682732e-4`, worse than the authoritative-parent diagnostic at
`2.5836112519572583e-4`. Small convex mixtures of the two p41 PASS branches
are themselves NONPASS and were not forwarded.

The alternative vector was not serialized because the branch is not selected;
the method is deterministic from the stored p40 PASS. No NONPASS vector was
stored or used as a seed. Equations, physics, gates, and the production lock
remain unchanged.
