- commit track-spec + meta-spec/plan into branch (HIGH: dangling `amends:` ref)
- inline parity evidence (cosine 1.0, max_abs_diff 2.01e-7) into HOTFIXES +
release notes; drop refs to deleted IMPL_REPORT/SPIKE_REPORT (MEDIUM)
- model guard: reject non-e5-large `model` before the 2GB download so
model_id() can't mislabel vectors (MEDIUM) + unit test
- parity test now covers BOTH query: and passage: prefixes (MEDIUM)
- guard encodings.first() index; document zero-attention/pooling invariant;
clarify embed_batch prefixing doc (LOW)
