Eight of nine group-3 tasks were rejected. Each defect was hiding a number, and the numbers are why the loop was not learning: - The fixed side was judged against the *vulnerable* side's function ranges. 191 of 227 pairs with a resolvable labeled span (84%) have different spans on the two sides, so a leak was recorded as silence, always in the direction that flatters Youden. - Round zero measured every family with the generalist. `family:unknown` earns no credit against any real family, so every family but `unknown` baselined at a structural zero and every noise floor with it. - The cross-family sweep counted absolute failures instead of negative flips. On a corpus where most pairs fail at round zero that rejects every round for damage it did not do. Unscorable rows voted too. - K runs was declared and never threaded; `pairs --k-runs` was parsed and discarded, and its only test grepped `--help`. - The meta-agent proposer was a stub, so `learning round` could never propose anything. It now composes MetaAgent.evolve against a scratch copy of the family directory, and `--proposals FILE` runs a recorded sequence offline. - `refused_holdout` was a vocabulary word no code path could produce, and the covering test accepted either outcome. - Cost was metered once, after everything had been paid for; a stage that raised left no record at all. - The corrected lever number was published beside the earlier one rather than in place of it, and the test named for that property never checked. - Refusals were `continue` statements: `Refusal.degradation()` existed and nothing called it. A train-split identical twin was reported as `split:train`, which is untrue. Test repairs that each changed a number: two split tests measured an `x = 1` fixture that teaches nothing whatever the rule says; two CLI scoreboard tests asserted against all-zero output produced by a stub that answers twice and puts its finding outside the labeled function.
