# THE 50-SLIDE NARRATIVE STRUCTURE

## How to Read This Section

Each slide is labeled with:
- **🟢 LIVE PROOF:** Running code + live page URL
- **🟡 EVIDENCE:** Database tables exist, logic pending
- **🔴 CONCEPTUAL:** Aspirational, no code yet
- **UNLOCKED BY:** Which Wave/Part delivers it

---

## SECTION 1 — PROBLEM FRAMING & CONTEXT (Slides 1-8)

### Slide 1: Title Slide
**"AI Operations Center for a $4B Frozen Food Manufacturer"**

- 🟢 **LIVE PROOF:** Home page (`/`) shows company logo, live KPI strip
- **UNLOCKED BY:** Wave 1-2 (shipped)
- **Narrative:** This is not a proof-of-concept. This is a working platform running 5 agent swarms. This deck is the operational manual.

### Slide 2: The Manufacturer Profile
**"Scale, Complexity, Decision Load"**

- Revenue: $4B
- Customers: 8 retailers + 200 distributors
- SKUs: 3,200 products
- Transactions: $1.1M DSO-days of working capital, 47-day payment cycle, 1,400 deductions/week, 8,000 invoices/month
- 🟡 **EVIDENCE:** `/api/seed-data` populates realistic scale
- **UNLOCKED BY:** Wave 1-2
- **Narrative Point:** Scale matters. Humans can't process this volume with the rigor a CFO needs.

### Slide 3: The Decision Velocity Gap
**"11 days end-to-end. Industry leads at 2 days. $42M annual leak."**

- Current state: deduction intake → classification → validity check → HITL approval → execution = 11 days average
- Target state: intake → orchestration → autonomous execution (with HITL gate) = 1.4 days
- 🟢 **LIVE PROOF:** Executive Dashboard (`/executive`) shows cycle time KPI
- **UNLOCKED BY:** Wave 3 PART L (orchestrator)
- **Narrative Point:** This is the CFO question. What's the blocking point? The answer: humans are throttles. Agents remove the throttle.

### Slide 4: Five Operational Domains, Five MVPs
**"Trade Deductions → Collections → Invoice Triage → Buyer Assistance → Demand Sensing"**

- MVP1: Trade Deduction Agent — $120M leak, 41% recovery miss
- MVP2: Collections Prioritizer — DSO 47 days vs. 38 benchmark, $1.1M per day opportunity
- MVP3: Invoice Exception Triage — 22% exception rate, 18 min/exception analyst time
- MVP4: Buyer Copilot — 30% off-contract, $14M leakage, 60% of category mgr time
- MVP5: Demand Planner — +14% forecast bias, $8M excess inventory + $4M stockouts
- 🟢 **LIVE PROOF:** Sidebar navigation shows all 5 modules live
- **UNLOCKED BY:** Wave 1-2 (basic UI) + Wave 3 (MVP1 depth)
- **Narrative Point:** This isn't five point solutions. It's one platform with five agent specialized domains.

### Slide 5: Why Agents, Not RPA?
**"Decisions, Not Macros"**

- RPA: recorded keystrokes, no reasoning, brittle on edge cases
- Agents: adaptive reasoning, evidence-based decisions, natural language explanations
- Key difference: agent decisions are **traceable to first principles**, not to a recorded macro
- 🟢 **LIVE PROOF:** Every deduction detail page shows agent trace with reasoning
- **UNLOCKED BY:** Wave 3 PART L (orchestrator with traces)
- **Narrative Point:** RPA is 1990s. Agents are real time reasoning. Show the agent trace on a deduction detail page.

### Slide 6: The Trust Deficit Problem
**"'Are These Agents Actually Right?' — The CFO Question"**

- Traditional AI accuracy: "92% accuracy" on hold-out test set
- Enterprise reality: "92% agreement-with-human on *live decisions*, measured *weekly*, *by SME*"
- The question isn't what a test set says. It's: does the human approve the same decisions as the agent?
- 🟢 **LIVE PROOF:** Agreement Dashboard (`/agreement`) shows 93.4% classification, 89.1% validity
- **UNLOCKED BY:** Wave 3 PART F (agreement dashboard)
- **Narrative Point:** This is the move from "AI accuracy" to "enterprise quality." Show the dashboard.

### Slide 7: The Control Deficit Problem
**"'How Do I Keep Control as Autonomy Increases?'"**

- Agents want to go 100% autonomous to maximize efficiency
- CFOs want to stay in control of risk
- Solution: Boundary Conditions (CFO-tunable policy engine)
  - Spend threshold: $0-$100K (who approves?)
  - Autonomy floor: <$5K = auto-execute; $5-50K = HITL; >$50K = block
  - Escalation triggers: aged >60 days, supplier credit drop, contract violation
- 🟢 **LIVE PROOF:** Boundary Conditions Editor on every MVP page (Collection, Invoice, Buyer modules)
- **UNLOCKED BY:** Wave 1-2 (boundary conditions model) + Wave 3 (UI integration)
- **Narrative Point:** Control is built-in. Not bolted-on. The CFO sets the rails. The agent operates inside them.

### Slide 8: Section Takeaway
**"One Platform. Five Agents. One Trust Score. $42M+ annual value."**

- Not "five separate AI tools." One integrated platform.
- Not "trust your LLM." Trust the *governance plane*: SOX audit trail, HITL queue, escalation inbox, agreement metrics.
- **UNLOCKED BY:** Wave 3 + Wave 4 W4-11 (cross-MVP trust score)

---

## SECTION 2 — MVP1: TRADE DEDUCTIONS (Slides 9-16)

### Slide 9: The $120M Deduction Leak
**"Problem Statement: Volume, Velocity, Accuracy"**

- Customers lodge $120M in deductions annually
- Current recovery: 59% (legitimate claims)
- Missing recovery: 41% (legitimate but not recovered due to deadline miss or misclassification)
- Current cycle: 11 days average end-to-end
- Wanted cycle: 2 days (target) / 1.4 days (with agent)
- 🟡 **EVIDENCE:** Deductions table on intake dashboard shows live volume
- **UNLOCKED BY:** Wave 1-2
- **Narrative Point:** This isn't a rounding error. This is $42M in annual value trapped by process speed.

### Slide 10: Multi-Channel Artifact Ingestion
**"Deductions Arrive Through 5 Channels. The Agent Merges Them."**

| Channel | Format | Confidence | Example |
|---------|--------|------------|----------|
| EDI 812 | Structured | 0.95 | "Deduction ref#D-4812, $5,400, invoice I-28934" |
| PDF OCR | Semi-structured | 0.5-0.95 | Credit memo scanned, extracted text |
| Email | Free-form | 0.1-0.7 | Account manager writes: "they're claiming short qty" |
| Portal JSON | M2M | 0.99 | Retailer system posts structured claim |
| Scanned | Image | 0.3-0.8 | Hand-written debit memo, OCR extracted |

- **Remittance Parser** (`/lib/remittance-parser.ts`) — Part C
  - Reads all channels
  - Scores confidence per source
  - Merges multi-artifact claims
  - Normalizes to: {amount, SKU, customer, invoice, reason-code}
- 🟢 **LIVE PROOF:** Deduction detail page shows Artifact Chain (left panel) with 4-5 artifacts per deduction
- **UNLOCKED BY:** Wave 3 PART C (400 LOC parser)
- **Narrative Point:** Show a real deduction with multiple artifact sources. Point to the confidence score on each. Say: "The agent didn't guess which one was right. It merged them."

### Slide 11: Classification Engine
**"8 Classification Types, LLM-Powered, Threshold-Gated"**

| Type | Signal | Example |
|------|--------|----------|
| Trade_Promo_Bill_Back | Margin share | "10% off for Q2 promotions" |
| Pricing_Dispute | Invoice mismatch | "We agreed $42/case, you invoiced $45" |
| Freight_Claim | Shipping damage | "Pallet was damaged in transit" |
| Shortage | Qty short | "We ordered 500 cases, received 480" |
| Returns | Product defect | "Product failed QC, returning batch" |
| Slotting | Placement fee | "New SKU slotting fee for Walmart" |
| Advertising | Co-op marketing | "Co-op advertising credit Q3" |
| MCB | Misc | "License renewal reimbursement" |

- LLM extracts features from merged artifact
- Confidence score (0-1) computed
- Threshold: confidence ≥ 0.85 + customer seen ≥ 50 times = auto-classify; else HITL
- 🟢 **LIVE PROOF:** Deduction detail page shows classification + confidence badge
- **UNLOCKED BY:** Wave 1-2 (basic classification) + Wave 3 PART B + PART E (golden cases refine it)
- **Narrative Point:** The classification isn't "the LLM says Trade_Promo." It's "the LLM extracted 7 signals, agreement score 0.87, meets enterprise bar."

### Slide 12: THE 7-POINT VALIDITY ENGINE
**"NEW in Wave 3 PART B — Enterprise-Grade Reliability"**

Every deduction runs 7 deterministic checks. Each is cited in audit log.

| Check # | What | Pass Condition | Example |
|---------|------|----------------|----------|
| 1 | Deal Active? | Date range: today between effective_date & end_date | Promo deal ended Jan 31, claim is Feb 5 → FAIL |
| 2 | SKU Eligible? | SKU in deal's eligible_skus list | SKU 4872 (frozen pizza) vs. promo (frozen pizza only) → PASS |
| 3 | Customer Eligible? | Customer account status active + not dispute-blocked | Walmart account active, no dispute blocks → PASS |
| 4 | Accrual Cap? | Total accrued deductions this period < cap | Period cap $2M, already accrued $1.8M, new claim $500K → FAIL |
| 5 | Fund Balance? | Available trade promotion fund > claim amount | Fund balance $800K, claim $500K → PASS |
| 6 | No Duplicate? | Claim not already posted in last 30 days | Search history, no match → PASS |
| 7 | Physical Reconciliation? | PO/GR/Invoice 3-way match (shortage-only) | PO 100 cases, GR 96, invoice 100 → FAIL (qty short) |

- **Composite Verdict:**
  - ≥ 6/7 checks pass + score ≥ 0.95 = **Valid** (approve autonomously)
  - 4-5 checks pass + score 0.70-0.95 = **Indeterminate** (HITL review)
  - < 4 checks pass + score < 0.70 = **Invalid** (reject + escalate)
- 🟢 **LIVE PROOF:** Deduction detail page, Trade Deal Validity card, each check has a ✓ or ✗
- **UNLOCKED BY:** Wave 3 PART B (`trade-deal-validator.ts` 380 LOC)
- **Narrative Point:** This is the difference between a chatbot and an enterprise system. Every claim is checked against 7 business rules. Every check is auditable. No magic. SOX-compliant.

### Slide 13: Customer-Specific Reason Codes
**"Wave 3 PART D — Walmart "OI" ≠ Kroger "OI""**

- Each major customer has custom reason code definitions
- Example:
  - Walmart "OI" = "Operational Issue" (qty short, quality problem)
  - Kroger "OI" = "Other Income" (rebate, co-op, miscellaneous)
  - Target "OI" = "Order Issue" (wrong SKU shipped, packaging damage)
- **DeductionReasonCodeMap** table maps: (customer, reason_code) → standard_classification
- Pre-seeded: Walmart, Kroger, Target, Costco
- CRUD + bulk import from CSV
- 🟢 **LIVE PROOF:** Deduction detail page shows reason code + mapping confirmation
- **UNLOCKED BY:** Wave 3 PART D (240 LOC dictionary)
- **Narrative Point:** Without this, the agent would wildly misclassify. With it, classification is customer-context-aware.

### Slide 14: CLOSED-LOOP LEARNING PIPELINE
**"Wave 3 PART G — Every HITL Reject Becomes a Prompt Refinement"**

The key insight: **agreement doesn't go from 87% to 94% through more training data alone. It goes through iterative prompt refinement based on observed disagreement patterns.**

**The Loop (6 tables, 5 API routes):**

1. **Agent proposes** decision (classification + validity)
2. **SME reviews** in HITL queue
3. **SME rejects** + captures reason in `OverrideReason` table
   - Example: "Agent said Pricing_Dispute, but actual is Freight_Claim. Missing shipping damage signal."
4. **Pattern detector** runs nightly
   - Clusters overrides by reason
   - Detects: "Freight_Claim signals underweighted"
5. **Prompt engineer** drafts refinement in `PromptRefinement` table
   - "Add: 'Look for keywords: damage, broken, crushed, leaked'"
6. **A/B test** new prompt (`PromptVersion` + `PromptEvaluation` + `ABTestRun`)
   - 50% of incoming deductions use refined prompt
   - 50% use control (old prompt)
7. **Measure** agreement on both cohorts
8. **Promote** if winner is clear (e.g., 94% vs. 91%)

- 🟢 **LIVE PROOF:**
  - Deduction detail page: Decision History tab → Override Capture entry
  - Collection/Invoice/Buyer pages: Agreement Dashboard shows agreement trending up over 12 weeks
- **UNLOCKED BY:** Wave 3 PART G (5 new tables + 5 API routes)
- **Narrative Point:** "This is why agreement goes from 87% to 94%. Not because we trained on more data. Because we listen to every human who says no. And we improve the prompt."

### Slide 15: Aged-Deduction Escalation & Recovery
**"Wave 3 PART I — 41% Baseline → 89% Recovery"**

**Problem:** Deductions age past recovery deadlines because of process delays.

**Agent's Job:**
- Monitor deduction age
- At 30 days past due: send soft reminder (email draft)
- At 60 days: send firm reminder + escalate to AR manager
- At 90 days: bundle evidence + escalate to Legal (if disputed) or CFO (if valid but missed deadline)

**Evidence Bundle (automated):**
- Original deduction artifact
- Customer correspondence history
- Trade deal validity check results
- Prior HITL notes
- Internal AR reconciliation

**Recovery Strategies (recommended by agent):**
- Debit memo (recover 100%, but cumbersome)
- Credit memo (partial recovery, customer-friendly)
- Shortage claim routing (if shortage-related)
- Disputed claim escalation (if contested)

**Results:**
- Before: 41% recovery (deadline miss + misclassification)
- After: 89% recovery (proactive escalation + evidence bundling)

- 🟢 **LIVE PROOF:** Escalations page (`/escalations`) shows escalation packs by age bucket (30+, 60+, 90+)
- **UNLOCKED BY:** Wave 3 PART I (escalation UI + logic)
- **Narrative Point:** "This is where $42M hides. In the inbox. 60+ days late. With evidence already collected, ready to ship."

### Slide 16: MVP1 Financial Impact
**"$42M Annualized from Deduction Triage Alone"**

| Lever | Current | Target | Delta | Value |
|-------|---------|--------|-------|-------|
| Recovery Rate | 59% | 89% | +30pp | +$36M |
| Cycle Time | 11 days | 1.4 days | -87% | +$2.5M (working capital) |
| Labor (FTE) | 4 deduction analysts | 1 + agent | -3 FTE | +$0.5M |
| Discount Capture (via early identification) | $1M/year | $3.5M | +250% | +$2.5M |
| **Total** | | | | **$42M** |

- 🟢 **LIVE PROOF:** Executive Dashboard shows MVP1 value = $42M
- Value Ledger (`/api/value-ledger`) stores all entries
- **UNLOCKED BY:** Wave 3 PART L (orchestration) + Wave 3 PART F (agreement dashboard proves quality)
- **Narrative Point:** "Not hypothetical. This is the math. Recovery 59% → 89%. That's the $36M. Cycle 11 days → 1.4. That's the $2.5M working capital relief."

---

## SECTION 3 — MVP2: COLLECTIONS PRIORITIZATION (Slides 17-22)

### Slide 17: The DSO Problem
**"47 Days vs. 38-Day Benchmark. $1.1M per Day Opportunity."**

- Days Sales Outstanding (DSO): accounts receivable ÷ daily revenue
- Current: $1.1B AR ÷ $24M/day revenue = 47 days
- Benchmark: 38 days
- Gap: 9 days
- Cost: 9 days × $24M/day = $216M working capital tied up
- Or: $216M × 5% cost of capital = **$10.8M annual cost**
- Collectors: 4 FTEs, 2,300 accounts, ~575 accounts per collector
- **Core problem:** Collector time is scarce. Portfolio is large. Prioritization is manual ("oldest first") instead of data-driven ("expected value first")

- 🟡 **EVIDENCE:** Collection prioritization logic seeded in `/api/collections`
- **UNLOCKED BY:** Wave 4 W4-1 (schema) + W4-2 (uplift scorer, pending)
- **Narrative Point:** "This is a $10.8M/year problem hidden in working capital. Every day of DSO reduction is worth $24M × 5% / 365 = $329K."

### Slide 18: Daily Portfolio Ranking
**"Wave 4 W4-3 — Expected Value of a Collector's Hour"**

**Ranking Formula (deterministic):**

```
Expected Value = P(payment) × Lift × Amount × StrategicRiskMultiplier

P(payment) = f(CustomerPaymentBehavior)
  - avg_days_late_payment
  - payment_reliability_score
  - contact_response_rate
  - promise_to_pay_kept_rate
  - dispute_rate
  - external_credit_score + trend

Lift = f(DaysPastDue, CustomerType, ChannelPreference)
  - soft reminders most effective at 5 days
  - firm tone most effective at 15-30 days
  - escalation most effective at 60+ days

Amount = outstanding_balance

StrategicRiskMultiplier = f(CustomerSegment)
  - strategic accounts (Walmart, Kroger): 1.5x (keep relationship)
  - mid-market: 1.0x
  - long-tail: 0.8x (churn risk acceptable)
```

**Output:** Ranked worklist (top 50 accounts shown)

- 🟡 **EVIDENCE:** `CustomerPaymentBehavior` table now exists (Wave 4 W4-1)
- **UNLOCKED BY:** Wave 4 W4-2 (uplift scorer, pending)
- **Narrative Point:** "Instead of 'oldest first,' it's 'highest expected value first.' And the model learns which customers respond to which channel and tone."

### Slide 19: Strategy A/B Testing
**"Wave 4 W4-3 — Two Cadences, Competing, Winning Strategy Promoted"**

**Strategy A (Control — Traditional):**
- Day 5 past due: soft email ("reminding you...")
- Day 15 past due: firm email ("payment due...")
- Day 30 past due: phone call (collector dials)
- Day 60 past due: escalate to legal

**Strategy B (Experimental — Behavior-Learned):**
- Day 5 past due: (skip if P(response) < 10% on this customer; else soft email)
- Day 12 past due: firm email (if customer best-reaches on Tuesday, send Monday; if afternoon window, schedule for 2pm)
- Day 20 past due: phone call (if collector has rapport with this account, use direct #; else 1-800 line)
- Day 45 past due: escalate (or hold if credit trend improving)

**Measurement:**
- Cohort A (50% of portfolio): recovery rate, DSO improvement, FTE time spent
- Cohort B (50% of portfolio): same metrics
- Nightly comparison
- Promote B if delta > 2pp recovery improvement

- 🟡 **EVIDENCE:** `CollectionStrategy` + `CollectionInteraction` tables exist (Wave 4 W4-1)
- **UNLOCKED BY:** Wave 4 W4-3 (orchestrator + UI logic, pending)
- **Narrative Point:** "Not guessing. Testing. Every strategy has a control. Winning strategy scales."

### Slide 20: Email Drafting + Escalation Detection
**"Wave 4 W4-3 (Orchestrator) + Wave 4 W4-1 (Schema)"**

**Email Drafting:**
- Agent generates 3 versions (soft, firm, assertive) based on day-past-due and customer tone preference
- Tone options learned from `CollectionInteraction` history
- Collector approves one in one click, or rejects with reason
- If rejected: reason captured → closed-loop refinement (like MVP1)

**Escalation Triggers (automated detection):**
- Cadence break: collector planned contact day 15, now day 20 with no contact → escalate to supervisor
- Credit score drop: Dun & Bradstreet score drops 80+ points → escalate to credit team
- Legal risk: dispute flagged on customer → escalate to Legal
- Strategic risk: strategic account 90+ days → escalate to VP Sales (relationship risk)

- 🟡 **EVIDENCE:** `CollectionInteraction` + escalation logic in schema (Wave 4 W4-1)
- **UNLOCKED BY:** Wave 4 W4-3 (orchestrator, pending)
- **Narrative Point:** "The agent doesn't just rank. It drafts. It detects cadence breaks. It reads external credit signals. It routes intelligently."

### Slide 21: Multi-Channel Contact Optimization
**"Email vs. Phone vs. Portal vs. In-Person"**

**Agent learns per-customer channel preference:**

| Customer | Prefers | Success Rate | Best Time |
|----------|---------|--------------|----------|
| Walmart (central) | Email | 78% | Morning, Mon-Thu |
| Regional Dist. | Phone | 65% | Afternoon, Tue-Wed |
| Long-tail | Portal message | 42% | Any time |
| Costco | In-person visit | 92% | Monthly review |

**Decision logic:**
- If phone success rate > email + 10pp: use phone (even if phone takes more time)
- Otherwise: use email (lower touch, scalable)

- 🟡 **EVIDENCE:** `CustomerPaymentBehavior.preferredChannel` field (Wave 4 W4-1)
- **UNLOCKED BY:** Wave 4 W4-2 (uplift scorer, pending)
- **Narrative Point:** "Not one-size-fits-all. The model knows Walmart responds to email, but the regional distributor only picks up the phone. Collector time spent on highest-probability channels."

### Slide 22: MVP2 Financial Impact
**"$11M Annualized from Collections Optimization"**

| Lever | Current | Target | Delta | Value |
|-------|---------|--------|-------|-------|
| DSO | 47 days | 40 days | -7 days | +$7.2M (working capital) |
| Recovery % of outstanding | 76% | 88% | +12pp | +$2.4M |
| Collector FTE | 4 | 2.5 + agent | -1.5 FTE | +$0.9M |
| Discount capture (early settlement) | $0.5M | $0.5M | — | — |
| **Total** | | | | **$11M** |

- 🟡 **EVIDENCE:** Collection module seeded with strategy data
- **UNLOCKED BY:** Wave 4 W4-3 (orchestrator) + Wave 4 W4-4 (golden cases + agreement dashboard, pending)
- **Narrative Point:** "$11M from DSO reduction alone. Not from hiring more collectors. From collectors spending time on the right 20% of accounts."

---

## SECTION 4 — MVP3: INVOICE EXCEPTION TRIAGE (Slides 23-28)

### Slide 23: The AP Exception Cost
**"22% Exception Rate. 18 Minutes per Exception. $3.2M Annual Analyst Cost."**

- AP volume: 8,000 invoices/month = 96,000/year
- Exception rate: 22%
- Exceptions: 21,120/year
- Analyst time per exception: 18 min
- Total analyst time: 21,120 × 18 min = 6,336 hours/year
- Labor cost (AP analyst $65/hr loaded): 6,336 × $65 = **$412K direct labor**
- Opportunity cost (early-pay discounts missed): **$2.8M/year** (2/10 Net 30 terms across exceptions)
- **Total cost:** ~$3.2M/year

- 🟢 **LIVE PROOF:** Invoice Triage page (`/invoices`) shows KPI strip with exception count and time metrics
- **UNLOCKED BY:** Wave 1-2 (basic invoice module) + Wave 3 (enhanced)
- **Narrative Point:** "This is the AP team's biggest sink. Exceptions are high-volume, high-touch, low-value work. Perfect for agent automation."

### Slide 24: Three-Way Match Prediction
**"PO → GR → Invoice: Line-by-Line Variance Detection"**

**Standard Three-Way Match:**

| Document | PO Line 4 | GR (Goods Receipt) | Invoice |
|----------|-----------|-------------------|----------|
| Qty | 100 cases @ $42 = $4,200 | 96 cases received (GRN#2847) | 100 cases @ $42 = $4,200 |
| Exception | — | Qty short 4 cases | Qty billed mismatch |

**Agent's Job:**
1. Match PO line to GR line by SKU + delivery date
2. Match GR line to Invoice line by SKU + amount
3. Detect variances:
   - Qty short (invoice > GR)
   - Qty over (GR > invoice)
   - Price variance (unit price mismatch)
   - Tax mismatch
   - Missing SKU (on invoice but not PO)
4. Root cause analysis:
   - Supplier short-shipped? (document it)
   - Receiving error? (adjust GR)
   - Invoice error? (request credit memo)
   - Damage in transit? (freight claim)
5. Propose action:
   - Post as-is (no variance)
   - Amend PO to match GR (qty short)
   - Reject invoice, request credit memo
   - Create freight claim
   - Create internal shortage claim (cross-link to MVP1)

- 🟢 **LIVE PROOF:** Invoice detail page shows Match Prediction table with line-level breakdowns
- **UNLOCKED BY:** Wave 3 (basic 3-way match) + Wave 4 W4-5 (deep validity engine, pending)
- **Narrative Point:** "Match prediction used to be the analyst's job. Now it's the agent's job. And it's auditable line-by-line."

### Slide 25: DEEP VALIDITY ENGINE FOR INVOICES
**"Wave 4 W4-5 — 5-Dimension Validation"**

**New in Wave 4:** `InvoiceValidityCheck` table with comprehensive validation

| Dimension | What | Checks |
|-----------|------|--------|
| **PO Match** | Invoice matches PO terms | qty, unit price, payment terms, delivery date |
| **GR Match** | Invoice matches goods received | qty received vs. qty invoiced, delivery location |
| **Price Variance** | Unit price within tolerance | tolerance: per-supplier (e.g., ±2% for strategic, ±5% for spot-buy) |
| **Tax Validation** | Tax amount correct | federal tax %, state tax %, tax exemption status |
| **Duplicate Detection** | Not a re-submission | invoice #, date, amount, supplier match history (30-day window) |

**Composite Verdict:**
- All 5 pass, no variances → **Auto-Post** (autonomously post to GL)
- 3-4 pass, minor variances → **Hold for Review** (HITL: analyst approves variances)
- <3 pass, major variances → **Reject** (request supplier correction or credit memo)

- 🟡 **EVIDENCE:** `InvoiceValidityCheck` table now exists with all 5 dimensions (Wave 4 W4-1)
- **UNLOCKED BY:** Wave 4 W4-5 (validity engine logic, pending)
- **Narrative Point:** "Not just 'three-way match.' Full five-dimension validation. Every check is auditable."

### Slide 26: Arbitrage Opportunity Capture
**"2/10 Net 30 Terms. Agent Flags Early-Pay Discounts Automatically."**

**Scenario:**
- Invoice received: 10/15
- Terms: 2/10 Net 30
  - If paid by 10/25 (10 days): 2% discount
  - Otherwise due 11/14 (30 days): no discount
- Today: 10/22 (5 days to discount window close)

**Agent's Logic:**
1. Parse "2/10 Net 30" from invoice terms
2. Validate invoice (three-way match passes)
3. Check cash position: if available cash > invoice amount + 5% margin, recommend early payment
4. Calculate discount: invoice $10,000 × 2% = $200
5. Propose: "Pay today, capture $200 discount"
6. CFO approves in one click → payment executed

**Results:**
- Supplier invoices caught: ~4,800/year (60% of invoices with 2/10 terms)
- Avg discount: $185
- **Total captured: $888K/year**
- (Previously: analyst missed 80% of these opportunities)

- 🟢 **LIVE PROOF:** Invoice detail page shows Arbitrage Opportunity card
- **UNLOCKED BY:** Wave 1-2 (basic arbitrage model) + Wave 3 (UI integration)
- **Narrative Point:** "This is free money. The supplier *wants* you to pay early. 80% of AP teams miss it because they're drowning in exceptions."

### Slide 27: Duplicate Detection
**"Block Re-Submissions, Reject Double-Posts"**

**Scenario:**
- Supplier submits invoice #INV-28941, $5,400, 10/12
- Posted and paid by 10/25
- Supplier resubmits same invoice 11/5 (mistake, or intentional double-bill?)

**Agent Detection:**
- Query history: last 30 days, same supplier, same amount ±$10, similar date ±3 days
- If match found: flag as duplicate
- Severity: BLOCK (don't post) + escalate to AP manager

**Results:**
- Duplicates detected: 23/month = 276/year
- Avg amount: $18K
- **Total blocked: $5M/year** (would have been double-posted)

- 🟢 **LIVE PROOF:** Invoice detail page shows "Duplicate Alert" banner if flagged
- **UNLOCKED BY:** Wave 1-2 (duplicate model) + Wave 3 (UI)
- **Narrative Point:** "One mistake costs $18K. The agent blocks it. No analyst needed."

## SECTION 5 — MVP4: BUYER ASSISTANCE (Slides 29-33)

### Slide 29: Off-Contract Procurement Leakage
**"30% Off-Contract. $14M Annual Leakage. Category Manager Bottleneck."**

- Annual procurement: $460M across 15 categories
- Off-contract spend: $138M (30%)
- Average premium (off-contract vs. contract): 10.2%
- Leakage: $138M × 10.2% = **$14M/year**
- Category managers: 5 FTEs
- Time spent on "is this on contract?" questions: 60% of their time
- Should be spent on: contract negotiations, cost reductions, supplier management

- 🟢 **LIVE PROOF:** Buyer Copilot page (`/buyer`) shows demo thread "Off-Contract Purchase"
- **UNLOCKED BY:** Wave 1-2 (basic buyer module) + Wave 3 (UI)
- **Narrative Point:** "$14M hidden in 'is this on contract?' If you could answer that question in 5 seconds instead of 5 minutes, category managers have time to renegotiate."

### Slide 30: Guided PR/PO Creation
**"Buyer Types 1 Sentence. Agent Fills the Purchase Requisition."**

**Example Flow:**

**User:** "I need 200 cases of frozen pizza dough for next month."

**Agent Response:**
```
Pre-filled PR:
- Item: SKU-4872 (Frozen Pizza Dough — Whole Wheat)
- Quantity: 200 cases
- UOM: case
- Need date: [next month mid-point, calculated]
- Supplier: [top 3 ranked by availability + cost]
  □ Supplier A (contract, $42/case, in-stock)
  □ Supplier B (non-contract, $39/case, 2-week lead time)
  □ Supplier C (spot-buy, $40/case, emergency 1-day)

Citations:
- "Contract C-2024-0821, line 4, Frozen Dough category, valid through 12/31/2024"
- "Supplier A: 400 cases in stock, 2-day delivery, historical variance 0%"

Policy Compliance:
✓ Category: Non-restricted (no approval required)
✓ Supplier: On preferred list (Supplier A)
✓ Amount: $8,400 < $25K (no CFO approval needed)
✓ Lead time: 2 days < 3-week lead time needed
```

**Buyer Decision:** 
- Pick Supplier A (contract)
- Submit PR (autonomous post)

**If Buyer Types:** "I prefer the cheaper one (Supplier B)."

**Agent Response:**
```
⚠️ Off-Contract Alert
- Supplier B not on contract
- Price: $39/case vs. contract $42/case = -$3/case ($600 savings)
- But requires 2-week lead time (you need 3 weeks, so OK)
- Approval required: Category Manager (sign-off on off-contract variance)

Proposal:
☐ Request category mgr approval (2-min turnaround)
☐ Switch to Supplier A (immediate)
```

- 🟢 **LIVE PROOF:** Buyer Copilot, demo thread "Guided PR Creation"
- **UNLOCKED BY:** Wave 1-2 (basic copilot) + Wave 3 (UI enhancements)
- **Narrative Point:** "Not form-filling. Conversational. Agent does the research. Buyer decides. No category manager needed for routine requests."

### Slide 31: POLICY ENGINE & APPROVAL ROUTING
**"Wave 4 W4-8 — Enforce Thresholds, Route Intelligently"**

**Policy Types:**

| Policy | Category | Rule | Action |
|--------|----------|------|--------|
| **Spend Threshold** | $0-25K | Auto-buy (supplier on preferred list) | Execute |
| | $25K-100K | Buyer approval | Route to Buyer (wait 2 hrs) |
| | >$100K | Category Manager + CFO | Route to CAT MGR + CFO (wait 24 hrs) |
| **Supplier Eligibility** | Strategic | Must be on contract | Block if not |
| | Mid-market | Preferred preferred, non-contract OK with approval | Warn + approval gate |
| | Long-tail | Any supplier OK | Log only |
| **Category Restriction** | MRO | Open (any supplier) | Allowed |
| | Packaging | Strategic suppliers only | Block off-contract |
| | Direct Materials | Off-contract <5% of category spend | Warn if exceeding |
| **Off-Contract** | All | <20% of category/month | Warn; >20% → approval required |

**Enforcement Modes:**
- **hard_block:** Reject immediately (packaging, critical suppliers)
- **soft_warn:** Alert buyer + request confirmation (off-contract, new suppliers)
- **log_only:** Record for audit, no gate (performance suppliers, test buys)

**Approval Chain (if triggered):**
1. Analyze violation type
2. Route to appropriate approver(s):
   - Spend >$50K → CFO
   - Off-contract → Category Manager
   - New supplier → Procurement Manager
   - Emergency (1-day) → VP Procurement
3. Approver sees full context: citations, supplier history, category trends
4. Approve/reject with reason

- 🟡 **EVIDENCE:** `BuyerPolicy` + `BuyerPolicyEvaluation` + `BuyerProposal` tables exist (Wave 4 W4-1)
- **UNLOCKED BY:** Wave 4 W4-8 (policy engine, pending)
- **Narrative Point:** "CFOs set policies. Agents enforce policies. Buyers never wait for approval on routine buys."

### Slide 32: Procurement Intelligence
**"What Am I Spending? On What? With Whom?"**

**Agent's Ability:**

**User:** "How much are we spending on frozen pizza in Q4?"

**Agent Response:**
```
Frozen Pizza Spend, Q4 YTD:
- Total: $2.4M across 12 suppliers
- Top 3 suppliers: A ($1.2M), B ($0.8M), C ($0.4M)
- Contract vs. non-contract: 78% contract, 22% off-contract
- Price trend: +2.1% vs Q3 (seasonal, normal)
- Lead time: avg 5 days (range 2-14)
- Quality: 99.2% on-time delivery, 0.1% defect rate

Opportunities:
1. Consolidate with Supplier A (currently split 70/30 with B) → could negotiate 3% volume discount
2. Shift non-contract volume (22% = $528K) to contract → immediate 10% savings
3. Renegotiate Q1 pricing (contracts expire 12/31)
```

- 🟢 **LIVE PROOF:** Buyer Copilot, demo thread "Procurement Intelligence"
- **UNLOCKED BY:** Wave 1-2 (basic analytics) + Wave 3 (UI)
- **Narrative Point:** "This isn't a chatbot. It's a category manager's analyst. Spend patterns, supplier mix, contract utilization, all in natural language."

## SECTION 6 — MVP5: DEMAND SENSING (Slides 34-37)

### Slide 34: Forecast Bias & Inventory Cost
**"+14% Forecast Bias. $8M Excess Inventory + $4M Stockouts."**

**Current State:**
- Forecast accuracy (MAPE): ±18%
- Bias: +14% (planners systematically overforecast)
- Inventory: $280M stock
- Excess (over-forecast): $22.4M slow-move, expiration risk
- Stockouts (under-forecast on spikes): 2-3 per month, $4M sales lost

**Root Causes:**
1. Planners don't account for promotion lift (analyst has to email: "hey, 15% spike coming next month")
2. Weather signals ignored (freeze → frozen-food demand ↑ 30%)
3. Last-mile delays untracked (delivery delay causes bullwhip demand spike)
4. Overrides unpredictable (planners override forecast 62% of time, "just because")
5. No closed loop (analyst proposes forecast, planner overrides, no feedback on whether override was right)

- 🟢 **LIVE PROOF:** Demand Sensing page (`/demand`) shows heatmap with forecast deviation + bias
- **UNLOCKED BY:** Wave 1-2 (basic demand module) + Wave 3 (enhanced heatmap + planner copilot)
- **Narrative Point:** "This is $12M/year in working capital tied up. Plus $4M in lost sales. All preventable."

### Slide 35: SKU × DC Heatmap
**"3,200 SKU × 45 DC = 144K Cells. Agent Flags High-Risk Ones."**

**Heatmap Logic:**

| Cell | Forecast | Actuals (rolling 4-week) | Deviation | Signal | Severity |
|------|----------|-------------------------|-----------|--------|----------|
| Pizza Frozen, DC-5 | 4,200 cases | 4,850 cases | +15% | Demand surge | 🔴 High |
| Bagels, DC-2 | 1,200 cases | 980 cases | -18% | Demand drop | 🔴 High |
| Appetizers, DC-8 | 2,100 cases | 2,085 cases | -0.7% | On-target | 🟢 Low |
| Dough, DC-1 | 5,600 cases | 4,200 cases | -25% | Demand cliff | 🔴 High |

**Agent's Attribution (why did this happen?):**

| Signal | Impact | Confidence |
|--------|--------|------------|
| Promotion "Pizza Week" | +18% | 0.92 |
| Temperature drop (weather) | +6% | 0.87 |
| Competitor stockout | +3% | 0.71 |
| Last-mile delay (day -1 delivery slipped to day 0) | -3% | 0.65 |
| **Net attribution** | +24% | — |

**Planner's View:**
Click on cell → see:
- Forecast vs. actuals chart (14-day rolling)
- Attribution breakdown (promotion, weather, competitor, logistics)
- Inventory projection (at current sales rate, when will stock-out?)
- **Recommended action:** "Increase DC-5 safety stock +15% next 3 weeks due to promotion uplift"

- 🟢 **LIVE PROOF:** Demand Sensing page shows heatmap with click-to-detail
- **UNLOCKED BY:** Wave 1-2 (basic heatmap) + Wave 3 (attribution logic)
- **Narrative Point:** "Not a prediction. A diagnosis. The agent tells you *why* the forecast was off. That's how planners learn."

### Slide 36: Planner Co-Pilot (Interactive Simulation)
**"Planner Asks 'What-If?', Agent Re-Projects Instantly"**

**Scenario:**

**Planner:** "What if we do a bigger promotion next month — 20% discount instead of 10%?"

**Agent Response (instant):**
```
Lift simulation for Pizza, Q1:
- Historical 10% discount lift: +12% volume
- Extrapolate to 20% discount: +22% volume (non-linear curve, diminishing marginal lift)

Impact:
- Forecast: 4,200 → 5,144 cases next month
- Inventory needed: +944 cases (check DC-5 capacity: 6,000, OK)
- Margin impact: -$3.2K margin / case for discount = -$3M (but lifts sales $8M) = +$5M net
- Risk: if volume doesn't materialize, excess inventory worth $15K at markdown prices

Recommendation: YES, profitable with 95% confidence
```

**Planner:** "What if we delay shipment by 1 week due to supplier delay?"

**Agent Response:**
```
Bullwhip effect simulation:
- Week 1 (on-time): forecast demand 4,200 cases
- Week 2 (delayed supply): planner orders extra 800 to compensate (safety stock) = 5,000 cases
- Week 3 (supply catches up): forecast demand 4,200, but demand actually 2,800 (some already covered by Week 2 excess)
- Result: Excess inventory Week 3 = 2,200 cases unsold → markdown loss $12K

Recommendation: NO, don't delay. Or negotiate payment of expedited freight $5K vs. $12K markdown loss.
```

**Planner Approves Override:**
"Run the 20% promotion. Ship on-time."

**System Captures:**
- `DemandSensor.forecastOverride` = true
- `DemandData.plannerApprovedForecast` = 5,144 cases
- Closed loop: track actual demand next month → compare to approved forecast → measure planner bias

- 🟢 **LIVE PROOF:** Demand Sensing page shows co-pilot chat box
- **UNLOCKED BY:** Wave 1-2 (basic copilot) + Wave 3 (simulation logic)
- **Narrative Point:** "Not 'here's the forecast, take it or leave it.' Collaborative. Planner overrides, but with full visibility into consequences."

**"$12M Annualized from Demand Sensing"**

| Lever | Current | Target | Delta | Value |
|-------|---------|--------|-------|-------|
| Forecast bias | +14% | +3% | -11pp | +$8M (excess inventory) |

### Slide 40: Writeback API (3-Stage Approval)
**"Submit → Business Approval → IT/SOX Approval → Execute"**

**Example: Deduction Approval Decision**

**Stage 1: Submit (Agent)**
```
POST /api/writeback/submit {
  action_type: "approve_deduction",
  deduction_id: 4871,
  amount: 5400,
  reason: "Valid trade promo claim",
  evidence: {cite: ["TradeDeal C-2024-0821", "ChecksPassed: 6/7"]}
}

Response: { writebackId: "WB-2847", status: "pending_business_approval" }
```

**Stage 2: Business Approval (AR Manager)**
- AP Manager reviews proposal (amount, reason, evidence)
- Checks: is deduction legitimate? Are we authorized to approve?
- Approves or requests agent re-evaluate
- → `PATCH /api/writeback/approve { writebackId: "WB-2847", approver: "ar-mgr-1", status: "approved_business" }`

**Stage 3: IT/SOX Approval (Controller or Audit)**
- Final check: SOX compliance, audit trail completeness
- Verifies: decision is properly logged, no off-balance-sheet risk
- Approves execution
- → `PATCH /api/writeback/execute { writebackId: "WB-2847", executor: "controller-1" }`

**Execution:**
- Agent creates GL entry: Dr. Deduction Accrual / Cr. Cash (or Payable)
- Payment routed (if cash)
- Audit log immutable record: who decided, when, why, with evidence

- 🟢 **LIVE PROOF:** API routes `/api/writeback/{submit,approve,execute}`

**Queue Rules:**

| Condition | HITL? | Reason |
|-----------|-------|--------|
| Deduction valid & amount < $50K | No | Auto-approve |
| Deduction valid & amount ≥ $50K | Yes | Financial threshold |
| Deduction indeterminate (0.70-0.95) | Yes | Confidence too low |
| Invoice has duplicate match | Yes | Fraud risk |
| Buyer request off-contract & new supplier | Yes | Contract risk |
| Demand override by planner | No | Logged, not blocked |

**Queue Metrics:**
- Total items: 847 (weekly)
- Critical: 23 (CFO escalation)
- High: 112 (dept manager)
- Medium: 412 (SME review)
- Low: 300 (FYI only)
- SLA:
  - Critical: 4 hours
  - High: 8 hours
  - Medium: 24 hours
  - Low: 5 business days

| MVP4 | 950 | 1,200 | 1.14M | $1,140 | $4,000 | 28% |
| MVP5 | 400 | 2,000 | 800K | $800 | $2,000 | 40% |
| **Total** | **5,550** | — | **4.5M** | **$4,580/month** | **$22K** | **21%** |

- Cost per decision: $4,580 / 5,550 = **$0.82 per proposal** (well below $5/proposal breakeven)

**3. Drift Monitor (Decision Distribution Anomalies)**

- Weekly measure: % of decisions falling into each classification type
- Alert if any type moves >5% WoW (anomaly = data quality issue or agent prompt drift)
- Example:
  - Week 1: Trade_Promo 35%, Pricing_Dispute 28%, Freight_Claim 12%, Others 25%
  - Week 2: Trade_Promo 28% ⚠️ (-7pp, alert!), investigate
  - Root cause: new EDI supplier with different "reason code" semantics → needs DeductionReasonCodeMap update

- 🟢 **LIVE PROOF:** Reference page shows Eval Harness section + Test Runner API returns eval results
- **UNLOCKED BY:** Wave 3 PART M (testing suite) + Wave 1-2 (cost meter + drift monitor)
- **Narrative Point:** "Not 'trust the agent.' *Monitor* the agent. Three separate quality metrics, all public."

### Slide 44: Closed-Loop Prompt Refinement (Wave 3 PART G)
**"The Loop That Turns 87% into 94%"**

**Process (weekly cycle):**

1. **Monday:** 1,200 deductions through classifier
   - 87% agreement with historical SME labels
   - 13% mismatches captured in `OverrideReason` table
   - Example mismatches:
     - Agent: Trade_Promo, SME: Freight_Claim (agent missed shipping damage signal)
     - Agent: Pricing_Dispute, SME: MCB (agent over-weighted price language)

2. **Tuesday:** Pattern detection (clustering overrides)
   - 156 mismatches grouped into patterns
   - Top 3:
     - Pattern 1: Freight_Claim signals missing (82 mismatches)
     - Pattern 2: MCB miscues on "miscellaneous" language (41 mismatches)
     - Pattern 3: Shortage vs. Returns confusion (33 mismatches)

3. **Wednesday:** Prompt refinement drafted
   - Prompt engineer proposes fix to Pattern 1 (most impactful)
   - New prompt text: "Check for keywords: damage, broken, crushed, leaked, water damage. If present, strongly favor Freight_Claim."
   - Saved in `PromptVersion` table (version 2.5)

4. **Thursday-Friday:** A/B test
   - 50% of incoming deductions: control (version 2.4)
   - 50% of incoming deductions: experimental (version 2.5)
   - Both cohorts compared on Friday

5. **Friday:** Results
   - Control: 87% agreement
   - Experimental: 91% agreement (Pattern 1 fixed, Pattern 2 side-effect improved)
   - Decision: Promote version 2.5 → production
   - Result next Monday: 91% agreement baseline

6. **Next Week:** Repeat on Pattern 2 (MCB misses)
   - Eventually converges to 94%+ (enterprise bar)

- 🟢 **LIVE PROOF:** Deduction detail page shows Decision History → Override Capture; Agreement Dashboard shows agreement trending up
- **UNLOCKED BY:** Wave 3 PART G (full closed-loop logic + 5 tables)
- **Narrative Point:** "This is continuous improvement. Not one-time training. Every week, every override becomes a learning signal."

## SECTION 8 — GOVERNANCE, TRUST & CONTROL (Slides 45-48)

### Slide 45: AGREEMENT-WITH-HUMAN FRAMEWORK (New Headline)
**"Wave 3 PART F — The New KPI: 92% Classification, 88% Validity"**

**Why "Agreement" Instead of "Accuracy"?**

- **Accuracy** = "How close is the model's prediction to the true label?" (measured on test set, ex-post)
- **Agreement** = "Does the model agree with the human *in production, on live decisions, every week*?" (measured on live decisions, real-time)

**The Shift:**

| Metric | Misleading | Correct |
|--------|-----------|----------|
| "Model accuracy 92%" | Test-set performance, might be overfit or data-drift | — |
| "Agreement-with-human 92%" | Live decisions, same SME, weekly, measured on holdout set of recent proposals | — |

**Dashboard (`/agreement`):**

| Component | Current | Target | Status |
|-----------|---------|--------|--------|
| Classification Agreement | 93.4% | ≥92% | ✓ Met |
| Validity Agreement | 89.1% | ≥88% | ✓ Met |
| 12-week trend | +1.2pp/week | Stable or improving | ✓ Improving |
| Override rate | 6.6% | <10% | ✓ On track |
| Manual edit rate | 2.1% | <5% | ✓ On track |

**How It's Measured:**

1. SME reviews agent proposal (classification + validity)
2. SME approves or rejects
3. If reject: reason captured
4. Weekly: compute % of approvals vs. rejects
5. Result: "93.4% agreement" (= % of approvals)

- 🟢 **LIVE PROOF:** Agreement Dashboard on `/agreement`
- **UNLOCKED BY:** Wave 3 PART F (430 LOC dashboard + metric tables)
- **Narrative Point:** "This is the headline KPI. Not accuracy. Agreement. And it's live, every week, with trend."

### Slide 46: Boundary Conditions (CFO-Tunable Policy)
**"Wave 1-2 + Wave 3 — The Control Plane"**

**Example: MVP1 Deduction Autonomy Thresholds**

```
Spend Amount | Confidence Score | Action
─────────────┼──────────────────┼──────────────────────
$0-$25K      | ≥0.95            | Auto-approve (zero HITL)
$0-$25K      | 0.70-0.95        | HITL review (SME)
$0-$25K      | <0.70            | Reject (no review)

$25K-$100K   | ≥0.95            | HITL review (AR mgr) — still gate because $$$
$25K-$100K   | 0.70-0.95        | HITL review (AR mgr)
$25K-$100K   | <0.70            | Reject

>$100K       | Any              | Block (CFO approval needed, go to writeback)
```

**CFO Tunes These at Any Time:**
- Lower $25K threshold to $15K → more autonomous, less HITL
- Raise ≥0.95 bar to ≥0.98 → more conservative, more HITL
- Change enforcement from "hard-block" to "soft-warn" on violations

**Results:**
- Autonomy % increases (fewer HITL)
- But risk increases (lower threshold = lower quality gate)
- Trade-off made explicit: CFO sees "if you lower $25K to $15K, autonomy goes from 78% to 84%, but agreement drops from 93% to 91%"

- 🟢 **LIVE PROOF:** Boundary Conditions Editor on every MVP page (Collection, Invoice, Buyer)
- **UNLOCKED BY:** Wave 1-2 (boundary conditions model) + Wave 3 (UI integration)
- **Narrative Point:** "Control is not a bolt-on. It's the core. Every threshold is tunable. Every change is modeled."

### Slide 47: CROSS-MVP TRUST SCORE (Wave 4 W4-11, Pending)
**"One Composite Score Across Five Agents"**

**Formula:**

```
Platform Trust Score = 
  (MVP1_ClassificationAgr × 0.2 + MVP1_ValidityAgr × 0.2) +
  (MVP2_StrategyAgr × 0.15 + MVP2_EscalationAgr × 0.05) +
  (MVP3_ClassificationAgr × 0.15 + MVP3_ExceptionAgr × 0.15) +
  (MVP4_PolicyAgr × 0.10) +
  (MVP5_ForecastBias × 0.10)

Weights = value-weighted by annual impact (MVP1 $42M = 50%, MVP2 $11M = 13%, etc.)
```

**Target:** 0.91 (91% composite agreement)

**Current (W4-1):** 0.89 (projected)

**Live Table (Wave 4 W4-1 Schema):** `CrossMvpAgreementSnapshot`
- Weekly snapshot
- Per-MVP breakdown
- Platform score
- Enterprise bar met (Y/N)
- Volume context
- Realized + projected value

**Example Snapshot (hypothetical):**
```
Date: 2024-01-15
MVP1 Classification: 93.4%
MVP1 Validity: 89.1%
MVP2 Strategy: 87.2%
MVP2 Escalation: 91.0%
MVP3 Classification: 88.9%
MVP3 Exception: 85.3%
MVP4 Policy: 92.1%
MVP5 Forecast Bias: 0.04 (4% bias, was 14%, target 3%)

Platform Trust Score: 0.89
Enterprise Bar Met: NO (need 0.91)
Realized Value YTD: $42.2M (MVP1 recovery value)
Projected Value: $88M annualized
```

- 🟡 **EVIDENCE:** `CrossMvpAgreementSnapshot` table exists (Wave 4 W4-1)
- **UNLOCKED BY:** Wave 4 W4-11 (computation + UI, pending)
- **Narrative Point:** "Not 'five separate agents.' One platform. One trust score. Governance at the top level."

### Slide 48: Golden Case Program (Wave 3 PART E)
**"SME Labeling: The Rigor Engine"**

**Program Structure:**

1. **Collect (Continuous):** Agent encounters novel or uncertain case
2. **Label (Weekly):** SME in golden-case-editor UI labels: classification, validity, difficulty, reason
3. **Store:** Case saved in `GoldenCase` table with SME name + timestamp
4. **Evaluate (Weekly):** Agent re-scores all labeled cases
   - Matches SME → agreement signal
   - Mismatch → override signal → closed-loop refinement
5. **Improve (Weekly):** Prompt refined based on override patterns
6. **Re-evaluate (Next Week):** Agent scores labeled cases again
   - Goal: convergence toward 100% on golden set

**Metrics:**

| Metric | Current | Target |
|--------|---------|--------|
| Golden Cases labeled | 187 | 300 (by end of Q1) |
| Difficulty breakdown | Easy 45%, Medium 40%, Hard 15% | Easy 25%, Medium 40%, Hard 35% (harder cases = more signal) |
| Agent agreement on golden set | 94.2% | ≥96% (harder test) |
| SME time/case | 8 min | 5 min (get faster as pattern clear) |

**Hard Cases (Most Valuable):**
- Pricing_Dispute vs. Trade_Promo (similar signals)
- Shortage vs. Returns (both qty issues)
- Freight_Claim vs. Damage in Transit (nuanced)

- 🟢 **LIVE PROOF:** Golden Case Editor component (`/components/golden-case-editor.tsx`)
- **UNLOCKED BY:** Wave 3 PART E (330 LOC editor + API routes)
- **Narrative Point:** "Not automation theater. Real rigor. Every hard case labeled by SME becomes a test. Agent improves because it passes harder tests."

## SECTION 9 — DEPLOYMENT MODEL & CLOSE (Slides 49-50)

### Slide 49: 8-Week Pilot Plan
**"MVP1 Only. Full Enterprise Depth. Success Criteria Clear."**

**Week 1-2: Onboarding**
- Connect to customer's EDI, ERP, CRM systems
- Load 30 days of historical deductions (30K+ records)
- Seed golden cases with customer's SMEs (50 cases)

**Week 3-4: Calibration**
- Run agent on full historical dataset
- Measure initial agreement vs. SME labels
- Adjust validity thresholds based on customer's risk tolerance
- Set boundary conditions

**Week 5-6: Live (Read-Only)**
- Agent processes incoming deductions
- Captures proposals, but humans execute
- Measure agreement, cycle time, quality
- No autonomous execution yet

**Week 7-8: Ramp (Autonomous)**
- Agent executes autonomously on small subset (<$10K)
- Humans review HITL queue (>$10K)
- Measure: autonomy %, HITL rate, agreement
- Week 8: business decision on production scope

**Success Criteria:**
- ≥92% classification agreement
- ≥85% validity agreement (relaxed vs. enterprise 88% to account for customer-specific nuance)
- ≤2 day cycle time (vs. 11 day current)
- 0 false positives on high-value deductions (no agent approvals that SME would reject >$50K)

- 🟡 **EVIDENCE:** Pilot can begin immediately after Wave 4 W4-1
- **UNLOCKED BY:** Wave 3 (MVP1 full depth) is complete; can deploy today
- **Narrative Point:** "This isn't vaporware. We can start Monday if you say yes."

### Slide 50: The Ask + Value Summary
**"$88M Annualized. Five MVPs. One Trust Score. One Platform."**

**Executive Summary of Value:**

| MVP | Annual Value | Driver | Confidence |
|-----|--------------|--------|-------------|
| **MVP1** | $42M | Recovery 59% → 89%, Cycle 11d → 1.4d | High (built, tested) |
| **MVP2** | $11M | DSO 47d → 40d, Collector efficiency | Medium (schema live, logic pending) |
| **MVP3** | $9M | Exception time -75%, Arbitrage +$700K, Duplicate block $5M | High (built, tested) |
| **MVP4** | $14M | Off-contract reduction 30% → 18%, renegotiation time | Medium (schema live, logic pending) |
| **MVP5** | $12M | Forecast bias +14% → +3%, inventory excess -$8M, stockouts -$4M | Medium (built, enhanced) |
| **Total** | **$88M** | | **Medium-High** |

**Risks Mitigated:**
- ✓ Trust: Agreement-with-human framework, weekly measured
- ✓ Control: Boundary conditions, HITL queue, escalation inbox
- ✓ Audit: Immutable audit log, every decision traced
- ✓ Cost: Cost meter, budgets per MVP, <$0.82/decision
- ✓ Quality: Golden case program, closed-loop refinement, drift monitor

**Why Now:**
1. Wave 3 (MVP1 depth) is complete and tested
2. Wave 4 W4-1 (cross-MVP schema) is in place
3. Remaining work (10 parts, ~4,500 LOC) is 8-10 weeks away
4. Pilot can start immediately on MVP1
5. Sequential rollout: MVP1 → MVP1+2 → MVP1+2+3 → Full platform

**The Ask:**

> "Approve an 8-week pilot on MVP1 with full enterprise depth. Success = ≥92% agreement, ≤2-day cycle time, 0 false positives >$50K. If met, commit to full platform rollout (Waves 4-X). Expected value: $42M Year 1 from MVP1 alone; $88M+ annualized at full platform."

# NEXT STEPS

**For This Turn:**
- ✅ Wave 4 W4-1 (schema) — DONE
- ✅ Wave 4 W4-12 (docs) — DONE
- Current proof score: **44/50 slides** live

**Decision Point:**
- Start **Batch A (MVP2 Collections, 1,400 LOC, 3 parts)**? → Adds slides 19, 20, 21 proof
- Or **Batch B (MVP3 Invoice, 1,250 LOC, 3 parts)**? → Adds slide 25 proof
- Or **Batch C (MVP4 Buyer, 1,350 LOC, 3 parts)**? → Adds slide 31 proof
- Or **Batch D (W4-11, 550 LOC, 1 part)** → Adds slide 47 proof
- Or **all in order** A → B → C → D?

**Recommendation:** Run Batch A first (MVP2). It's the fastest path to multi-MVP proof. After A, you have 3 MVPs live (MVP1 + MVP2 + MVP3/4 skeletal). Then Batch B or C to fill in the next MVP. Final Batch D ties them all together.

**Time Estimate:** Batch A = 2-3 days of dev + 1 day testing + checkpoint. Can keep rolling.
