Share lazy encoding state through capture and pruning without retaining parent links or copying synchronization primitives. Keep MTS2 bytes and caller-owned output unchanged; allocate exactly sized node and checkpoint buffers. Check the original wire encoder, concurrent pruning and encoding, output ownership and recovery. Benchmark moving windows including the default 128-root cadence; document retained-memory costs and the all-new-window limit.
Record moving-window results at the real 128-root cadence, retained-memory tradeoffs and unchanged cold-window costs. Keep raw benchmark artifacts outside the source tree; do not infer live voting gains from staging measurements.

Prepare transaction-status publication and move checkpoint work off replay while retaining synchronous AlreadyProcessed checks.
Based on the independent epoch-rewards correctness branch so those fixes remain outside this diff. Retarget to alpenglow-dev after that prerequisite merges.
Validation: full replay and rewards suites pass; combined build and vet pass. Historical Zen 5 default-cadence checkpoint encoding improved from about 195 to 85 ms; this is encoding CPU time, not voting latency or checkpoint disk latency.
