 1. `zig build test` and `-Dintegration` 0 failed; fmt clean.
-2. Field verification on the released build (the Pi deploys releases, not branches, so this necessarily follows the cut — owner-ordered 2026-08-21): one 24-hour run spanning several autocheckpoints and a retention pass — WAL resets normally, writeback falls materially, no dropped batches; measured as process write_bytes AND device sectors (/sys/block/mmcblk0/stat). The rpi-nixos-iac session runs it; a bad result reverts the constant in a follow-up patch release.

Field verification on the released build (the Pi deploys releases, not branches, so this necessarily follows the cut — owner-ordered 2026-08-21): confirm the WAL resets normally, writeback falls materially, and no batches drop. What to measure and over what window is the deployment side's call; a bad result reverts the constant in a follow-up patch release.
