jyvikoandClaude Opus 5.5 67e05548b1 oracle: an ill-conditioned quantity gets a wider fixture band; Scordelis-Lo re-blessed ...

Main's oracle job failed at 8cba3a7: scordelis-lo-roof-solid u_z moved from
-0.3014029226397275 (blessed before #50) beyond its 1e-9 band. The case is a
thin shell (R/t = 100) of one layer of hex20R solids, ill-conditioned, so
rounding alone moves u_z by about 1e-9 relative: on macOS #50's multithreaded
supernodal factorisation moved it by 8.2e-10 (to -0.3014029223929), #52's
interpolation order by a further 1.3e-10 (to -0.3014029223541), and Linux
CI by slightly more, past the band. #52 kept the lattice geometry the same.
The result itself is unchanged at the 1e-9 level (0.33% from the
reference).

A quantity may now set `fixture_relative` (with a required
`fixture_reason`) for a wider fixture band; Scordelis-Lo uses 1e-7 and is
re-blessed. Moved-fixture messages print full precision.
