A candidate-driven detector can only judge sites something else enumerates,
so the enumerator caps recall. Measured over the 58 scorable web pairs before
building anything:
pattern ruleset: 12.1% ceiling -- and the misses are not near-misses, the
ruleset finds nothing at all in most of these files
semantic IR: 96.6% ceiling, a median of ten call sites and bindings
inside the labeled function
The ruleset would have capped us at 12.1% against the 64.9% the unconstrained
loop already reaches. That design was one commit from being built.
Two corpus defects found on the way, both mine from task 4.1. The overleaf
excerpt started mid-import, because `_declarator_start` walks back to the
nearest `}` and Overleaf writes JavaScript without semicolons, so the nearest
one was inside `import { expressify }`. It then ended mid-object-literal,
because registration mentions were appended as bare lines. Neither parsed,
and a pair that cannot be parsed cannot be scored. Registration mentions now
expand to the statement that contains them; the ceiling moved 94.8% -> 96.6%.

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 4.1. A new excerpt mode keeps the labeled handler with its decorators and
every statement outside it that registers the handler by name, so guards living
in decorators, routers and middleware travel with the pair. Comment and string
mentions never count.
The closed mechanism vocabulary gains the three obligation ids, catalog rows
accept an additive obligation field validated against the closed operation
kinds, and the pair scorer counts a finding tagged with that obligation inside
the labeled function as a detection. Rows without the label run the same code
as before.

Task 8.4 (Req 10.6, 5.1).
- harvest.merge_recipes appends recipes by name and never rewrites
existing rows.
- vibe-py/build_recipes.py --pointers: the 40 LLM-generated repositories
without a license become vendored = false rows (80 pairs, agent,
seeded) appended to recipes.toml; unlicensed human repos stay skipped.
- agent-vfc/build_recipes.py --from ... --pointers [--cache]: unlicensed
agent-authored fixes become title-tier pointer rows whose function
label is derived from the cached excerpt (30 added from a fresh
662-candidate search); TOML booleans rendered correctly.
- catalogs regenerated: vibe-py 115 rows (35 vendored + 80 pointer),
agent-vfc 59 (29 + 30); no excerpt is vendored for any pointer row.
- `pairs --slice vibe-py --pointers` scores both provenances (human 35,
agent 80); the default run skips 80 pairs with pointer_pair_skipped;
suite and gates unchanged. README/docs name the nightly command.

Task 8.3 (Req 10.1-10.5).
- pairs.py: catalog rows with vendored = false carry their harvest recipe
and no excerpts; evaluate_catalog harvests them into
OPENULTRASAST_PAIR_CACHE (default ~/.cache/openultrasast/pairs) only
when `pairs --pointers` or OPENULTRASAST_PAIRS_NETWORK=1 allows the
network, otherwise records pointer_pair_skipped (a failed fetch is
pointer_pair_fetch_failed with detail); a warm cache never scores
without the switch. select_vendored for tests and gates.
- harvest.py: materialize_pointer harvests into the cache without the
license requirement (nothing is redistributed); redaction applies.
- catalog_gen.py: emits pointer rows with recipe fields; training
manifests skip them.
- pair_gate and improve/evolve.evaluate_profiles score vendored pairs
only; cli `pairs --pointers`; .gitignore covers the cache path.
- tests: loader, skip/degradation, cache hit, fetch failure, warm cache
with network off, profile gate exclusion, harvest and generator paths;
conftest keeps every test offline whatever the shell exports.

Tasks 3.1, 3.2 (harvest library) and the Scorer-owned naming helper.
- semantic/functions.py: one source of function names for scorer, overlay
and catalog generator (declarator wins over parser name; JS/TS bare-param
arrows and undeclared methods are <anon>; C++ Class::method resolves to
its unqualified tail; Perl sub; statements never name).
- benchmarks/pairs/harvest.py: shared library with name / line_range /
hunk / enclosing modes, comment-blind masking (triple-quote aware),
upstream_start headers, code-safe quoted-only redaction.
- benchmarks/pairs/catalog_gen.py: derive function labels and sinks from
the declarator at the mapped sink location, CWE-family sink tokens,
--prune with refusal when nothing derived, fails loud without the
package; vfc/harvest.py and vfc/generate_catalog.py become shims.
- tests/test_pair_harvest.py replaces test_vfc_harvest.py.
