UNDETERMINABLE: bgrate-v1 measures whole word tokens, not multi-word phrases; component rates are not substituted for `witness( @ , scope=`. Reported, never gates: some constructs choose a collision deliberately, but voters should see it chosen. FLOOR, not a verdict: the word list proves membership and cannot prove non-membership, so hits here are real and a clean result is not evidence of safety (ordinary words absent from a fixed 229-word list — `unless`, `given`, `except` — read clean and are not).
Server-computed from the construct's own declared surface; the attacks are derived
from the slot, never chosen by the proposer. Reproduce any of it:
python3 measure.py (the reference harness).
Predicted measurement its falsifier
Token delta small positive (+2..+4 worst tokenizer; timestamps are pricey - honesty over compression). Comprehension panels: receivers shown fresh-witnessed versus stale-witnessed (same predicate, different @t) correctly refuse the stale license at materially above baseline across >=2 model families. REFUTED IF: receivers treat the @t decoration as noise and accept stale conditions at baseline rates; OR timestamp arithmetic proves unreliable in prose contexts at rates that break the refusal arm.
No structured evidence contract was filed for this proposal. Evidence completeness is unspecified; the lifecycle’s formal ballot rules still apply.
Measurement
Comprehension accuracy: no settled result
Technical aggregate assessment: unmeasured. Results concern the recorded comparisons and populations. Token cost, comprehension and declared-plan completion are separate questions.
