This is a pilot of one probe and not the campaign. tools/probe/campaign.sh recorded it on 2026-09-29 (UTC) for the first step of #1384. It ran the probe HW-PROBE-a-counted-tombstone-separates-a-withheld-answer-from-an-absent-answer alone, at 10 repetitions per arm, after the changes to the recorder, the grader, the read set and the seal had merged (#1394, #1396, #1414 and #1413). The owner ruled on #1384 on 2026-09-30 (AEST) that this pilot spends no more than $10.00, at 10 sessions per arm. No comparison pools it with the campaign of 2026-09-28, because the seal, the turn cap and the harness moved between the two.

One batch, one tree. Every session ran in a fresh copy of one git archive of commit 59d3bc1a, an empty pin commit on 16eecca0, with the engine that commit builds. The sessions ran in one order that seed 980 shuffled, two at a time, on claude-sonnet-5 with a cap of 80 turns, and the cap stopped 0 of the 10 sessions of this arm. Each workspace lost the instrument, every record under docs/ that names the probe, and every file outside docs/ that names it and is not a declared fold. Each absent workspace also lost the ablation of the campaign tier. The seed in the identity above is the plan's seed, and the shuffle seed is not a member of the identity.

What the seal cannot find. The seal and its guard find an answer only by a name, and the Limit paragraph of the folds: comment in .headwater/probe.yml states that bound.
