- Extract cache mismatch logic into reusable cache_mismatch_reasons() function for cleaner validation and consistent miss reporting - Expose memory_budget_bytes() for external callers (aligned exporter) - Optimize rebuild_stack() with incremental layer updates when only one angle parameters change, avoiding full reprojection overhead - Remove unused seed_per_angle parameter from alignment wizard - Simplify cached_rf_image() DC masking with cleaner early exit logic - Clean up internal state tracking with explicit origin caching Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>

"""Headless GUI test: drives SrasViewerWindow through the real Qt widgets,
|
|
signals and worker threads under the offscreen platform plugin.
|
|
|
|
Covers the interactions a manual smoke test would: load, switch angles and
|
|
channels, background DC precompute, lazy FFT compute, threshold and bg-sub
|
|
changes, the alignment wizard end to end (pre-rotation, correlation, manual
|
|
nudging, crop, export), aligned view, ROI draw/move, and CSV export.
|
|
|
|
NOTE: this module is one ordered integration sequence over a single shared
|
|
window — the tests build on each other's state and must run in definition
|
|
order (pytest's default within a module). Run the whole module, not single
|
|
tests.
