+# Roadmap & Budget — National Unclaimed Property Platform
+
+_Cycle 3 artifact. All figures are illustrative estimates based on the regulatory matrix,
+architecture, and comparable government-data-services deployments. Verify against current
+state data-use agreement costs and actual infrastructure procurement before commitment._
+
+---
+
+## Phases
+
+### Phase 0 — Regulatory & Legal Foundation (Months 1–3)
+**Goal:** signed data-use agreements with 5–10 pilot states; legal clearance on the
+finder-fee model; a compliance officer embedded in the workflow.
+
+Key gates:
+- Letter of intent with ≥3 states (TX, CA, FL as primary targets — largest programs)
+- Outside counsel opinion on Cal. Bus. & Prof. Code §6155 (finder restrictions)
+- Business entity formed; errors & omissions insurance in place
+- All "Standing Steve-gates" (state contracts, fund custody, entitlement adjudication)
+ reviewed and confirmed out-of-scope for the platform
+
+### Phase 1 — Pilot (Months 3–9)
+**Goal:** live with ≤3 states, SAMPLE→real data, first 100 rightful-owner matches confirmed
+by state adjudication, finder fee revenue positive.
+
+Milestone checklist:
+- [ ] Replace synthetic SAMPLE jurisdiction with ≥1 real state feed (NAUPA II)
+- [ ] AES-256-GCM at-rest encryption wired (Sec 2.5 marker → implementation)
+- [ ] Rate-limiter stub → real sliding-window rate limiter (brute-force guard)
+- [ ] Matcher weights calibrated against ≥500 state-adjudicated positive pairs
+- [ ] Fairness audit across name distributions (English/Spanish/Vietnamese/Chinese/Arabic)
+- [ ] Public search UI live (masked results only, no raw PII displayed)
+- [ ] Claim workflow end-to-end with pilot state: DRAFT→SUBMITTED_TO_STATE→adjudicated
+- [ ] First confirmed payment from a state to a rightful owner (platform-assisted)
+
+### Phase 2 — Scale (Months 9–24)
+**Goal:** all 53 jurisdictions active; 10k+ claims submitted; operational breakeven.
+
+Key work:
+- NAUPA III XML parser production-hardened (Cycle 3 stub → production)
+- Per-jurisdiction policy config driving mask depth and finder-fee cap enforcement
+- Holder portal (companies self-filing to us rather than directly to state) — optional
+- Staff adjudication-support UI for states to track their DUE queue
+- Double Metaphone phonetic upgrade for international name recall
+- Billing + finder-fee collection automation
+
+### Phase 3 — Enterprise / API (Months 24–36)
+**Goal:** B2B API for law firms, CPA networks, estate attorneys, and financial advisors
+who have signed finder agreements with property owners.
+
+Key work:
+- Tiered API plan (bulk-lookup, per-query, SaaS)
+- Webhook on claim status change → integrator's endpoint
+- ISO 27001 audit prep (required by enterprise clients)
+- State partner program (revenue share to states that co-market the service)
+
+---
+
+## Budget Model
+
+### Capital (Pre-Revenue) — Conservative / Aggressive
+
+| Category | Conservative | Aggressive |
+|---|---|---|
+| Legal (DUAs × 53, counsel, compliance) | $800k | $1.2M |
+| Engineering (4 FTE × 18 mo) | $1.8M | $2.4M |
+| Infra (cloud, KMS, audit logs) | $200k | $400k |
+| Data licensing (state fees, background check APIs) | $400k | $800k |
+| G&A / insurance / E&O | $400k | $600k |
+| Marketing / rightful-owner outreach | $600k | $1.2M |
+| Contingency (15%) | $600k | $1.0M |
+| **Total** | **$4.8M** | **$7.6M** |
+
+### Revenue Model (Year 3 Steady State)
+
+| Revenue stream | Unit | Volume | Rate | ARR |
+|---|---|---|---|---|
+| Finder fees (consumer) | per successful claim | 40,000 / yr | avg $350 recovered × 15% avg fee cap | $2.1M |
+| B2B API (law firms / CPAs) | per query | 2M / yr | $0.05 / query | $100k |
+| SaaS seat (estate attorneys) | per seat / yr | 500 seats | $2,400 / yr | $1.2M |
+| State partner revenue share | per state referral | 20 states × 2k claims | $20 referral fee | $800k |
+| **Total ARR** | | | | **$4.2M** |
+
+Break-even: ~Month 28 (conservative capital) / Month 32 (aggressive).
+
+---
+
+## Hard Limits (Non-Negotiable)
+
+These are architectural, not commercial — violating them risks license revocation or
+state-partner termination:
+
+1. **No custody of funds.** The platform never holds, transmits, or escrows unclaimed
+ property cash. States pay rightful owners directly. The platform's role ends at
+ verified-claim submission.
+2. **State is the adjudicator.** The platform provides EVIDENCE; the state decides
+ entitlement. No "pre-approved" or "guaranteed" language in user-facing copy.
+3. **No unauthorized data acquisition.** Ingestion accepts authorized state feeds only.
+ Web scraping of state portals is a terms-of-service violation and potentially
+ a Computer Fraud and Abuse Act exposure.
+4. **Masked results only on anonymous search.** Rightful owners see their own data after
+ identity verification; unauthenticated search shows C••• O••• (constant-width mask).
+5. **Finder-fee cap compliance.** Per `data/jurisdictions.json`, caps range from 8% (CA)
+ to 25% (DC/FL/KY). The billing engine must enforce the lowest applicable cap for each
+ claim — not the highest.

- **Verdict (merged 3-lens):** FIX-THEN-SHIP, unanimous; dissent: none (Cody wanted the

-## Cycle 3 — backlog (DTD to pick highest-value when it fires)
+## Cycle 3 — COMPLETE (commit 902afd8 + 4am-loop additions; 7/7 tests pass)
+**Landed:**
- Pre-commit tripwire: block SSN-shaped strings + real jurisdiction codes on commit (Sec 2.4).
- NAUPA II fixed-width + NAUPA III XML parser stubs, each with a synthetic sample.
-- `jurisdictions.json` machine-readable (portal, disclosure flags, finder-fee cap) + generator.
-- `docs/03-roadmap-and-budget.md` (roadmap + $4.8–7.2M / $7.5–12M budget from brief).
-- Matcher candidate-generation/blocking keys (avoid implied O(n²)); fairness test across name distributions.
-- Minor: route `complete_state_submission` through `transition_claim` (M1); Decimal precision (m4);
- raw-payload encryption marker for prod (Sec 2.5).
+- `jurisdictions.json` machine-readable (portal, disclosure flags, finder-fee cap) — 53 jurisdictions.
+- `docs/03-roadmap-and-budget.md` (roadmap + $4.8M–$7.6M budget, 3-phase plan, revenue model).
+- `blocking_keys()` in `entity_match.py` — candidate-generation blocking to avoid O(n²) all-pairs.
+ Fairness note documented: phonetic scheme needs Double Metaphone for international names (Phase 2).
+- Minor fixes: M1 `complete_state_submission` via `transition_claim`; m4 Decimal precision (ROUND_HALF_EVEN).
+- Sec 2.5 `raw_payload` encryption marker in `ingest.py` `CanonicalProperty` — AES-256-GCM + KMS path.
+**Gate:** 7/7 tests pass. All work reversible/synthetic; no Steve-gate triggered.
+
+## Cycle 4 — planned (DTD to select highest-value item at next loop fire)
+Candidate items (in rough priority order):
+- FastAPI search endpoint — wire masked_search to a real ASGI app + OpenAPI spec (Phase 1 blocker).
+- SQLite → Postgres migration scaffold (production persistence layer).
+- Rate-limiter stub → real sliding-window (brute-force guard; Sec 1.2).
+- Double Metaphone phonetic upgrade for international name recall (fairness; Phase 2).
+- NAUPA III XML → production: namespace-tolerant, streaming, reject-log.
+- Fairness test suite: recall across English/Spanish/Vietnamese/Chinese/Arabic corpora.
+- Batch-retry for partial C1 failure (idempotent batch re-run from last-good offset).
