### 1.2.1 Tier C Fingerprint Runtime Contract
Tier C function fingerprint matching is implemented as deterministic offline-safe byte-window analysis:
- `FingerprintExtractor` derives basic-block hashes, CFG hash, string-reference hashes, constants, and call-targets from bounded binary byte windows (not seed-only synthetic placeholders).
- `SignatureMatcher` applies configurable weighted matching across basic-block, CFG, string-reference, and constant signals.
- Golden CVE fixtures include required high-impact package coverage for `openssl`, `glibc`, `zlib`, and `curl`, and verification checks enforce this coverage during feature rechecks.
