Multi-probe bootstrap wₐ departure at 7.8σ.
Same failure mode as the w₀ headline: the diagonal-covariance bootstrap shortcut inflated it; full-covariance treatment gives 3-4σ. Quarantined by the founder's own audit on 2026-07-09.
QUARANTINED — covariance_diagonal_shortcut
This significance was produced with a diagonal-covariance bootstrap shortcut that discards supernova correlations and inflates σ. The full-covariance treatment of the same data gives 3–4σ. Caught by the founder's own audit. Clears when: a full-covariance recalibration bundle reproduces the claimed significance — or a kill test buries it.
TENSION — the registry's self-check flags this claim
Declared contradiction with USR-2026-0001 PROVISIONAL — “Dark energy evolves: a CPL (w₀, wₐ) fit to DESI DR2 BAO + CMB + Pantheon+ beats ΛCDM...”. One of these claims must eventually fall.
Declared contradiction with USR-2026-0003 PROVISIONAL — “The evolving-DE preference appears in all three SN compilations refit through one...”. One of these claims must eventually fall.

Status, honestly
covariance_diagonal_shortcut. Status here is computed from evidence — the author cannot set it, and neither can we. Independent reproduction would move it; nothing else will.
