Three defects, two of them the same shape as ones already rejected once:
- The meta-agent proposer still could not propose. `MetaAgent(inner_model=)`
takes a ModelConfig; it was handed a model name, a `# type: ignore` hid
that from mypy, and a bare `except Exception` turned the resulting
AttributeError into `meta_agent_failed` -- which reads exactly like the
model declining. The composition is now a seam a test can pin, and a
construction error is re-raised rather than reported as a quiet round.
- `ousast pairs --hunter` crashed in its documented form: the K floor landed
with `--k-runs` still defaulting to 1. The covering test always passed
`--k-runs 4`, which is why nothing noticed.
- 28 rows (12% of the corpus) resolved a span on the vulnerable side and
none on the fixed side, so every fixed-side finding read as outside the
labeled function and the pair scored as silence whatever the detector
said. `fix_function` now reaches the catalog and the scorer, and the
generator derives it from the fixed excerpt for the 25 trap rows that
never declared one. Measured after: 0 rows.

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.
