Ledger is 232 / 0 open nonconformances; the two podman compose issues are both resolved and nothing is in flight. Two entries are CORRECTIONS rather than additions, and that is the point of the refresh. The trap entry on podman's compose delegation asserted the provider talks to the docker daemon; measured, podman points it at its OWN socket. That error survived two batches and produced two wrong fixes and one wrongly-premised issue. And the entry saying podman cannot run containers in this dev container was recorded from two real errors that turned out to be unconfigured prerequisites, not sandbox limits — both are now handled by the devcontainer scripts, so a local podman run is a real measurement. New rules, each paid for this session: a hypothesis written into an issue still reads as settled and mine was wrong three times on one issue; an environment limit remembered from an error message may be a setting nobody configured; an honest lane's number gets worse before it means anything; a test fix that moves the failure to a different line is progress, so read the line; a plausible mechanism is not evidence, so re-run before making a global concurrency change on one data point; and a permission classifier refusing a privilege escalation can simply be right. The queue loses its first item and the Podman sub-item gains real numbers — 30 build tests plus 433 integration tests, six exclusions each named with a measured reason. The arc intro records that with upstream files exhausted, the yield has moved from mining upstream tests to making deacon's own lanes honest: batches 25 and 26 found four defects between them, none from reading upstream.

A fresh session reading `.config/nextest.toml` will find the reasoning in place, but the cross-lane cost belongs in the traps list too: the change slows smoke tests everywhere, not only on Podman, and the narrower alternative is named in case that cost ever matters.

That's the substance of this refresh:
DOCKER_HOST=unix://$XDG_RUNTIME_DIR/podman/podman.sock, plusDOCKER_BUILDKIT=0). That error survived two batches and produced two wrong fixes and one wrongly-premised issue. The image really was in docker's store — because deacon was runningdocker composeitself, not because of anything podman did.newuidmap: write to uid_map failed,fuse: device not found) that turned out to be unconfigured prerequisites, not sandbox limits. Both are handled by the devcontainer scripts now, so a local podman run is a real measurement.New rules, each paid for this session
Queue and arc
The first queue item is gone, and the Podman sub-item gains real numbers: 30 build tests plus 433 integration tests, six exclusions each named with a measured reason. Remaining on #30: GPU passthrough.
The arc intro now records the shift — with upstream files exhausted, the yield has moved from mining upstream tests to making deacon's own lanes honest. Batches 25 and 26 found four defects between them, none from reading upstream.
