…1637) (#3721) Audit current pool defaults (COPY_BUFFER_SIZE = 128 KiB, max_buffers = available_parallelism()), document the workloads they were tuned for, and call out where the defaults underprovision (1M-file parallel bursts) and overprovision (sequential single-threaded transfers, long-lived daemon mode). Cover the adaptive grow/shrink policy from #1638-#1641, the OC_RSYNC_BUFFER_POOL_SIZE and OC_RSYNC_BUFFER_POOL_STATS env vars from #1643, and the memory cap interaction from #1188. Close with sizing rules of thumb for operators and open questions for the pending #1642 benchmark.

Trim the audit to the five-section sizing brief: implementation overview, default capacity and per-buffer size with line refs, sizing assumptions (target concurrency, per-thread reuse, memory budget), trade-offs (smaller pool vs larger pool, shared singleton, resizer cadence), and five improvement proposals (workload-derived sizing, CLI flag for OC_RSYNC_BUFFER_POOL_SIZE per #1643, instrumentation hooks, idle drain, memory-cap-aware adaptive ceiling). Drops the verbose history, recommendations, and pending-benchmark questions that belong in #1642 follow-up notes.
