Tasks 3.3 and 4.1.
- vfc curl and openssl-cve-2021-3449 excerpts re-harvested through the
shared library: whole functions with upstream_start headers, the
vendored key redacted code-safely, no truncated bodies.
- vfc/recipes.toml carries mode, fix_path and function anchors;
training/manifest.jsonl regenerated.
- Juliet CWE-121 strcpy pair gets its buffer declarations back so the
vulnerable side is a real overflow again.

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.

Harvest 176 isolated vuln-vs-fix functions (109 CVEs, 352 training rows)
into benchmarks/pairs/vfc with provenance and a JSONL training manifest.
Score the slice as an honesty dashboard (ousast pairs --slice vfc);
keep the pair gate on the local fixtures only.
Regex inventory stays the proposer. MAP attaches promote/demote/unadjudicated/coverage
from intra-file taint (tree-sitter when a grammar parses, Python ast as last resort).
Deep sandboxes promotions only, ordered by the existing heuristic ranker plus optional
OpenRouter mechanism recall. The SAST pair slice scores overlay outcomes; the stage-1
detection gate and local pair gate stay inventory-only.
