Make the OpenGait-studio demo drop unpaced frames before they grow the silhouette window. Separate source-frame gap tracking from paced-frame stride tracking so runtime scheduling matches the documented demo-window-and-stride behavior.
Add regressions for paced window growth and schedule-frame stride semantics.
Use buffered frame indices for emitted window bounds to stay accurate across detection gaps, and align select_person tests with the 4-field return contract introduced for frame-space bbox support.
Align bbox coordinate handling across primary and fallback paths, normalize Both-mode raw mask rendering, and tighten demo result typing to reduce runtime/display inconsistencies.
Add preprocess-only silhouette export and configurable result exporters so demo runs can be persisted for offline analysis and reproducible evaluation. Include optional parquet support and CLI visualization dumps while updating tests and tracking notes for the verified pipeline/debug workflow.
Introduce focused unit, integration, and NATS-path tests for demo modules, and align assertions with final schema and temporal contracts (window int, seq=30, fill-level ratio). This commit isolates validation logic from runtime changes and provides reproducible QA for pipeline behavior and failure modes.
