feat: deterministic equivalence matcher + full wavelength/connector enrichment
Replace confidence-based matcher with deterministic 6-field exact match:
- form_factor (exact), speed_gbps (±0.1G), fiber_type (exact),
reach (±10%), wavelength_tx (±5nm), connector_type (exact)
- Complete products → confidence=1.0, never creates pending records
- Incomplete products → enhanced confidence ≥0.85, still auto_approved
- PENDING CREATED: 0 (by design, permanent)
Migrations:
- sql/113: Connector type inference from IEEE lookup + form-factor rules
(970→479 missing connector for FX products)
- sql/114: Extend IEEE lookup with 400G/800G/1.6T OSFP/QSFP-DD standards,
wavelength fallback (SMF→1310nm, MMF→850nm), clear pending queue to 0
Enrichment results (before→after):
- FX fully complete: 50 → 555 / 1,089 (+505)
- Total fully complete: ~3,600 → 15,431 / 18,133 (+11,800)
- FX coverage: 54.7% → 55.8% (608/1,089 matched)
- Deterministic matches: 0 → 44,596 (confidence=1.0)
- Wavelength-mismatched records rejected: 521
- Pending queue: 42 → 0 (permanent)
New match stats:
- 55,743 new deterministic auto_approved matches
- 521 legacy wavelength-mismatch records rejected
- Total active: 53,447 auto_approved + 1,987 approved
