second_pass_op="upscale_2x" hands a scene back at twice the latent size while
every LATER scene is still built from latent_template at the original size.
Everything that crosses a scene boundary — carried overlap frames, the anchor's
continuation, the soft join, the JoyAI memory frame, per-scene guide sources —
is spliced into a chunk on the template's grid, so the second scene died on the
shape mismatch and the combination was simply unavailable.
One choke point, _match_template_resolution, brings the carried material back
before it is used, applied at the three places a finished scene crosses into the
next one. Each scene still samples and OUTPUTS at 2x: only what is carried gets
resampled, and only downwards, which is the direction that survives it — those
frames exist to say "continue from here", which a resample preserves far better
than invented detail would.
Identity no-op when the grids already agree, so any run without a resizing op is
bit-identical. Audio has no spatial axes and is never touched. A stale
noise_mask is dropped rather than reapplied at the wrong scale, and a resample
that throws costs continuity with a console line, not the run.
No grid guard on the chain blend: second_pass and second_pass_op are run-level
settings applied to every scene, so a chain cannot hold two resolutions — every
scene is upscaled or none is. Both tooltips said this combination dropped
multi-scene; they now say how it works.
Also: About reads "FunPack 3" with the codename on its own line, rather than
attaching the major to the codename.
