Carry explicit local date intervals instead of inferring the day from clock
order. Cluster width, delivery, adoption, and reports keep the actual civil
date; adopted date is stored separately from the reported birth_date.
Algorithm identity is scoring-9 / spec-v5. Scoring weights, confirmation
thresholds, and Skill version are unchanged. Isolated Linux final-3 gates
passed; four pre-existing Python failures remain. This is not a production
release.
Replace machine-specific float hashes with strict score and matrix byte comparisons. Keep quick bridge coverage and document duplicate collection. Verify Windows/Linux float behavior and in-memory candidate-date reversal; record the separate-machine acceptance gap and BUG-984 end-to-end blocker.

Add date-isolated caches and regression coverage, align scoring identity, and freeze full research reruns while preserving historical artifacts. Record unresolved cache/receipt identity and end-to-end acceptance gaps for branch review only.
