The loop has now survived CB-WP-0001 end to end and is revised from what
that pass actually taught, recorded in
history/260731-inner-loop-retrospective.md.
Held up: the adversarial review (one blocking and three significant
findings on its single use, resolved with new measurements rather than
argument), the parity-cap rule, the provisional U-item mechanism, and
the ADR gate.
The gap: both serious errors in the pass were measurement errors, and
the loop caught neither. Review reads prose; these were claims about
numbers. In both cases a harness ran successfully while doing no work —
a JS harness timing rejected no-ops, and a Rust benchmark computing
throughput for rounds that never completed.
v1.0 adds:
- Measurement validity: a harness must assert it performed the work it
reports. A number from a run that cannot prove it did the work is void.
- Metric feasibility: every metric names its instrument and is checked
reachable against the contracts in its own spec.
- No silently-ignored input; decisions get commands, not defaults;
scaffolds are exercised or marked; coverage gates that count tags say
so.
- Evidence must state what a comparison does not support.
- The chaos roll is recorded even when it changes nothing, so a
mechanism that never fires is visible rather than assumed.
CB-WP-0001 is complete: 9/9 tasks done.
