Adds the requirements baseline for the pipeline redesign:
- SPEC.md — software requirements with Current/Gap deltas per item, so the
document doubles as a work list.
- requirements.md — stable flat IDs (AR/DP/IR/GR/VR) with parent traces,
priorities, statuses, and a per-requirement verification plan. Replaces the
thematic A1..E8 scheme, which had already produced an A1a and an out-of-order
E6; IDs are now permanent and never reused.
- IMPLEMENTATION-PLAN.md — phased work.
The central change is AR-012: presence follows track extent rather than
per-frame recognition, so a window starts when an actor appears rather than
when the recogniser first succeeded. anneal_sec and extinction_sec are
withdrawn rather than retuned — a track that survives its own gaps leaves them
nothing to do.
Verification is shaped by CI running on an N100 with no dGPU: the existing
HDF5 dump makes everything downstream of embedding replayable on CPU, which
covers the bulk of the redesign.
