Status: Complete. The combined candidate was compared with the pre-optimization
baseline across all local sizes, complementary benchmarks, and all four recorded
PromptKit workloads. Consumer configuration and public contract tests passed.
Acceptance rests on reproducible allocation reductions; the maintainer confirmed
that busy-host timing is not a reliable comparison here. See the

Status: Complete. Retained changes, revisions, allocation comparisons,

are recorded in the [final handoff](startup-benchmark.md#final-consumer-verification-and-handoff).
No required verification remains for this scope. Release preparation and
publication remain separate work.
