+## DEV 1 KiB histogram writes (source candidate)
+
+`VhostMetrics::complete` now writes one exclusive histogram bin for each
+completed exchange instead of up to 11 cumulative atomics. Both Prometheus
+exporters reconstruct `le` and `+Inf` at scrape time. Unit tests cover boundary
+semantics. This change has not been compiled or benchmarked: see
+`docs/PROXY_1KB_COUNTERS_DEV_0.34.0.md`.

+## DEV 1 KiB cache counter follow-up
+
+See `docs/PROXY_1KB_COUNTERS_DEV_0.34.0.md`. Cache domain metrics no longer
+lock the HOT store on BYPASS; analytics cloning is deferred until the queue
+has capacity. The new **source** remains uncompiled in the editing environment.
+For quick 1,040-byte loopback diagnostics with ApacheBench (not a production
+acceptance benchmark), use `python3 scripts/performance/ab_1kb_dev.py --help`.
+The authoritative long-run comparison remains `benchmark.py` with pinned
+CPU sets, an explicitly equal upstream idle pool and multiple `wrk` repeats.
