- bench_baseline.md: Phase 2 numbers vs Phase 1. Decode/hash counters
byte-exact unchanged (micro 2/2, macro 6/5), throughput equal-or-better.
occupied_mem_delta flat by design (retained-memory metric dominated by
archive-stored messages; refc frees the eliminated transient copies
deterministically so they never accumulate). No residual deep-copy bug.
- phase2_mutation_audit.md: classification of every field-mutation and
nil-safety sweep hit (FINE vs FIXED).
