The meta-agent round journalled `no_proposal`. The real cause was an
authentication failure: `_model_config` hard-coded the anthropic provider
while the detector was talking to DeepSeek and no ANTHROPIC_API_KEY exists
here. The composition itself was fine -- MetaAgent constructed, evolve
started, budget $5 -- and the trace was thrown away.
`no_proposal` covered two different worlds: a proposer that considered the
facts and declined, and one that could not start at all. The journal now
carries the proposer's own reason, and the vendor comes from
`[harnessx] provider` instead of being assumed.

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.
