Fixture Gallery — Resolution Ladder (v3.4)¶

This is the resolution-detail view of the v3.3 fixture gallery: the same four Core-runnable GRIN smoke fixtures sampled at increasing grid density. More rays do not introduce a new transport model.

Reading Boundary¶

This page records retained Core fixture runs across declared sampling-density tiers. It is not a Godot comparison, image or pixel comparison, parity claim, physical validation, renderer-equivalence claim, or proof. A passing tier means only that the fixture completed under its recorded Core run checks.

Baseline grid -> Compact -> Gallery detail -> Extended

The tiers alter sampling density, not fixture GRIN parameters. Generated copies change rayGrid and scale the existing maxMisses run guard proportionally; canonical fixture files are not modified.

Run History / Correction Note¶

The initial generated mini-tier copies retained an unscaled, overly conservative maxMisses ceiling. That configuration produced early failed attempts. The generator was corrected so temporary resolution copies preserve the canonical fixture's proportional maxMisses allowance, and the final retained runs use that corrected configuration.

Those early attempts are part of the development history, but they are not the final ladder result. Canonical fixtures remained unchanged. The final result is 12 of 12 attempted smoke, mini, and standard runs passing; all four high-tier entries are deferred by the declared v3.4 scope policy.

Resolution Variant Identity¶

grin_radial_smoke_resolution_variant has a native baseline grid of 41x22, compared with 40x22 for the other fixtures. Its one-column sensitivity is therefore meaningful at the baseline tier only. The generated compact and gallery-detail tiers intentionally use the same 80x44 and 320x176 footprints as the rest of the family; this does not mutate the canonical fixture.

Deferred Tier¶

Extended 640x352 is not run in v3.4 (scope stop). This is a policy deferral, not a failed run. Gallery detail completed for every fixture, and v3.4 stops at that declared target rather than expanding artifact volume without a new need.

Claim Boundary¶

Core fixture artifact generation only.
Not a Godot comparison.
Not image or pixel comparison.
Not parity.
Not physical validation.
Not renderer equivalence.
Resolution tiers describe recorded Core runs only.
