# Scoring engine v1 (Stage 2)

Nightly `matchGrants` workflow (05:15 UTC, after embeddings) — the plan's "SQL gates, vectors rank" hybrid.

## Flow, per candidate org (NH + good standing + primary ICP)

1. **Profile embedding** — v0 stub: NTEE-derived mission text (`buildOrgMissionText`) embedded as `RETRIEVAL_QUERY`, stored in `org_profiles` at confidence 0.2. The Stage 4 research profiler upgrades the row in place; this workflow doesn't change.
2. **Retrieval** — `serverListEligibleGrantsForOrg`: one SQL statement enforcing the cheap hard gates (status open, embedded, deadline ≥ 21 days, ceiling ≥ $10K) with pgvector cosine ranking; top 50 per org.
3. **Remaining gates in TS** — entity eligibility (`entryAdmitsEntity`: conservative pattern matching over Grants.gov applicantTypes prose; ambiguous entries do NOT admit) and geography (word-boundary state code + full state name). `application_form_supported` is **deliberately ignored** for pass/fail (2026-07-16 manual-first decision — draftability verified by hand for top leads); its failure still lands in `rationale.gateFailures`. Failed pairs are not stored.
4. **Deterministic subscores** (`scoreMatch`, pure, tested): mission fit 30 (similarity 0.45–0.75 → 0–30) · capacity 15 (award 10–75% of revenue = sweet spot) · competition 15 (state-restricted ≫ national) · effort 10 · runway 5 (3–10 weeks ideal). **Funder precedent (25) not yet awarded** — achievable max is 75 until the 990-PF index lands; `subscores` jsonb keeps the full breakdown for reweighting. Easy win = total ≥ 50.
5. **Upsert + hero** — pair-keyed upsert that never touches review fields (a human's reject stands even when scores move); `serverAssignHeroMatch` marks the org's top non-rejected gate-passing match.

## First live run (2026-07-16)

64 orgs × top-50 grants → 3,200 matches, 0 gate failures (corpus was pre-filtered to nonprofit-eligible, federal = geography-unrestricted), **0 easy wins, max 39/75**. That's the system being honest: the current corpus is 200 NIH-dominated federal research grants — wrong pond for $100K–$5M NH service nonprofits (similarity ceiling ~0.58). The engine's next real gains are corpus-side: NH state agency sources, 990-PF foundation ingestion, full Grants.gov detail backlog, real effort estimates.
