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.

The catalog generator fills `fix_date` from the recipe at the precision the
recipe has -- a full ISO day when one was recorded, otherwise the year.
Every harvested recipe carries a year and almost none carries a day, and
writing `-01-01` would turn a year into a claim about a month. A row counts
as post-cutoff only when its earliest possible date is after the cutoff, so
a coarse date can under-claim the clean slice but never over-claim it.
Each family now reports the same numbers over the rows fixed after the
cutoff, beside the whole number and never instead of it, with the undated
count on its own line. Without a configured cutoff every scoreboard says so
rather than inventing one: guessing a model's training cutoff and then
publishing a contamination number from the guess would be worse than
reporting none.

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.

Eight of the ten vendored access-control rows had no named handler at all,
so every one of them would have scored `missing_context` forever rather
than as a detector miss. After the re-harvest nine are named and the tenth
states its reason.
The handler-context mode now carries the class its framework registers,
multi-line decorators, and commented-out guards -- `#@token_required`
above a ThreatByte handler is the entire bug. Where the registration lives
in another document (connexion's `operationId`, an express router), a
recipe names `context = [...]`, the harvester writes that stanza per side,
and the pair materializes both files at their repository-relative paths so
the entry-point mapper sees the layout the project has. `harvest_recipe`
fetches every blob before the first write and the driver takes `--report`,
so a failed fetch leaves a reviewed excerpt exactly as it was.
Two defects the re-harvest exposed: `.mjs` was not a known suffix, so the
one pair vendored as an ES module had no file target at all; and
`_python_route_access` matched auth words inside decorator prose, reading
`@ns.doc(description='... without proper authorization checks')` as a
guard. Recorded in the hygiene artifact: nine of the ten duplicate groups
sit on both sides of the split, which the repository-level split cannot
see.

Task 3.9. Five entry points make the classified detector set reachable:
classify a corpus and report the classifier against itself, score a catalog by
family, run round zero, run one evolve round, and publish every number from its
artifacts. The pairs command gains a runs-per-pair flag, since the family scorer
needs more than one.
Every step degrades with a reason rather than failing: with no chat endpoint the
run says so and still records what it could measure without a detector, and a
missing configuration directory is written from the current hunter prompt rather
than being an error. Artifacts are keyed by model throughout, so comparing a
second detector is a flag rather than a rewrite.
Both matrices are green and all three gate outputs stay byte-identical.

Task 3.8. A number in a roadmap that nobody can regenerate is a claim, not a
measurement. One entry point now writes them all from the committed artifacts
and puts the denominator beside each: how many pairs could be scored, why the
rest could not, which taxonomy version scored them, the noise the family shows
against itself, and what the run cost per pair it got right. Every table says
whether hierarchical partial credit could apply, which today it cannot.
The roadmap section is replaced in place between markers rather than appended,
so the file cannot accumulate a stale number beside a fresh one, and running the
command twice without new artifacts changes nothing. With no baseline recorded
it says so instead of printing an empty table.
The corrected mechanism-lever number travels with the rest: detected five of
seventeen at a negative Youden once only train-split pairs teach, against seven
when every pair taught, with the difference named as what holdout pairs stopped
teaching. Round zero now records what it spent so the cost column has a source.

Task 3.7. A round proposes one change for one family and then lets the evidence
decide whether it stays. The stages run cheapest first: a train minibatch, then
the family's held-out pairs, then every other family. Each stage scores several
runs per pair, and asking for fewer than three is refused outright, because a
single run misses most real changes.
The family directory is snapshotted before the change, so every outcome other
than acceptance leaves the tree exactly as it was found: a tie, a regression on
either side, another family below its floor, a proposal that reaches beyond its
directory, or a round that crosses its cost cap. Acceptance bumps only that
family's version and records which configuration won which pair.
Every outcome is journalled, including having no proposal at all, and the round
directory holds the proposal, the scores, the pair identities behind the
attribution counts and the detector trajectories, all redacted, so a round can
be replayed and its attribution audited rather than taken on trust. A round
number is never reused.
Recorded while writing the sweep: with per-family directories a change cannot
reach another family, so the sweep is a floor check over every other family at
the moment this round would land, not a causal claim about this change.

Task 3.3. Before anything learns, every family gets the same detector and is
measured against itself. Running a pair several times at the same settings does
not give the same answer, because the chat provider offers no seed, so the
spread between runs is real and unavoidable. That spread is the family's noise
floor and it becomes the budget a later round must stay inside before a
cross-family change counts as a regression. Choosing a budget instead of
measuring one would be a guess dressed as a threshold.
A pair the corpus already marked unscorable is never run: spending model calls
on a row that cannot be scored buys nothing and would put its noise into a floor
where it does not belong.
Artifacts are keyed by detector model, so a second model is baselined by
changing the model and running again, and the comparison table reads both side
by side. A model swap never touches a configuration, which is what makes the two
numbers comparable and reconsidering the model cheap. The web slices are the
default selection and the memory-safety family is measured with its floor marked
as never gating a round.
