## Measurability Validation

### Functional Requirements

**Total FRs Analyzed:** 155 (focusing on new FR141–FR155)

**Format Violations (new FRs):** 0 — System-behavior format consistent with established PRD style (FR65, FR133, etc.)

**Subjective Adjectives Found:** 0

**Vague Quantifiers Found:** 0

**Implementation Leakage in FRs:** 5 occurrences (see Implementation Leakage section below)

**FR Violations Total:** 5 (all in new FR141–155, all implementation leakage category)

### Non-Functional Requirements

**Total NFRs Analyzed:** 41 (focusing on new NFR38–NFR41)

- **NFR38:** Specific metric (3 seconds), capacity (500 nodes / 1000 edges), measurement method (skill invocation to first interactive frame) — Pass ✓
- **NFR39:** Measurable via defined test (LLM adds node/edge with no external schema) — Pass ✓
- **NFR40:** Behavioral constraint, verifiable by checking no deletions occur during emission — Pass ✓
- **NFR41:** Verifiable by disabling network access — Pass ✓

**Missing Metrics:** 0
**Incomplete Template:** 0
**NFR Violations Total:** 0

### Overall Assessment

**Total Requirements:** 155 FRs + 41 NFRs = 196
**Total Violations:** 5 (all implementation leakage, not measurability failures)

**Severity:** Warning (5 violations in new Knowledge Graph FRs)

---

## Traceability Validation

### Chain Validation

**Executive Summary → Success Criteria:** Intact ✓
- New "Zettelkasten-inspired knowledge graph" bullet traces to new success criterion "Engineers can open the BMAD knowledge graph..."

**Success Criteria → User Journeys:** Intact ✓
- "Knowledge graph accurately reflects all traceability relationships" → Yael, Noam, Alon journey extensions
- "End-to-end traceability chain navigable" → Alon governance journey

**User Journeys → Functional Requirements:** Intact ✓
- Yael (orphaned nodes, traceability gaps) → FR143 (bidirectional index), FR154 (filtering)
- Noam (PRD coverage gaps, requirements with no outbound edges) → FR143, FR148, FR154
- Alon (governance, confirmed inbound edges, provenance) → FR142 (provenance fields), FR143, FR148-150, FR153 (tooltip)

**Scope → FR Alignment:** Intact ✓ — Capability Area #17 maps to FR141–FR155

### Orphan Elements

**Orphan Functional Requirements:** 0
**Unsupported Success Criteria:** 0
**User Journeys Without FRs:** 0

### Traceability Matrix (Knowledge Graph FRs)

| FR Range | Source Journey/Objective |
|---|---|
| FR141–143 (data model, index) | Capability #17, Noam/Alon journeys |
| FR144–147 (JSON format) | "LLM-friendly JSON" in Capability #17, Exec Summary |
| FR148–150 (skill emission) | "automatic traceability" in Exec Summary, Success Criteria |
| FR151 (open-graph skill) | Yael/Noam/Alon journeys (`/open-graph`) |
| FR152–155 (visualization) | Success Criteria, Yael/Noam/Alon journeys |

**Total Traceability Issues:** 0

**Severity:** Pass — traceability chain fully intact for all new content.

---

## Implementation Leakage Validation

### Leakage by Category

**Algorithm/Approach (new):** 1 violation
- FR152: "force-directed interactive visualization" — specifies rendering algorithm. Should be "interactive graph visualization" (what), not "force-directed" (how).

**UI Element (new):** 1 violation
- FR154: "via checkboxes in the visualization panel" — specifies UI control type. Should be "via filtering controls" (what), not "checkboxes" (how).

**Internal Mechanism (new):** 1 violation
- FR148: "atomically: read current JSON, add new nodes/edges, write back" — describes the internal write mechanism. The atomicity requirement is valid; the read-write sequence belongs in architecture.

**Integration Protocol (new):** 1 violation
- FR151: "`vscode://file/{absolute-path}#{anchor}` URI scheme" — specific URI format is an integration protocol detail. The capability (navigate to document anchor) is valid; the URI scheme belongs in architecture.

**Rendering Implementation (new):** 1 violation
- FR155: "all JavaScript and CSS is inlined" — specifies the rendering implementation mechanism. The capability (self-contained, no external dependencies, air-gapped) is valid and should remain; "inlined" is the how.

**Note on intentional product design decisions (NOT violations):**
The following appear implementation-like but are intentional, capability-defining product decisions consistent with the PRD's established style (see FR123's CLI flags, FR133's YAML schema, FR480-519's full schema block):
- JSON format choice and flat structure — defines the LLM-friendly format, which IS the capability
- File paths (`knowledge-graph.json`, `knowledge-graph.html`) — product artifact locations
- Node ID format (`filename#heading-anchor`) — the graph identity contract
- Edge field names and schemas — the graph data model, which IS the product

### Summary

**Total Implementation Leakage Violations:** 5 (all in new FR141–155)

**Severity:** Warning (exactly 5 violations)

**Recommendation:** Remove algorithm, UI element, and mechanism specifics from 5 FRs listed above. Preserve the capability intent — move implementation choices to architecture. All violations are in the newly added Knowledge Graph FRs.

## Domain Compliance Validation

**Domain:** `software_engineering_development_methodology`
**Complexity:** Medium (developer tool with defense/MIL-498 component)

**MIL-STD-498 compliance:** Documented in Domain-Specific Requirements section ✓
**Enterprise SDLC governance:** Documented ✓
**Audit trail:** ai-audit-trail skill documented (FR48) ✓
**Air-gapped / disconnected environments:** FR44, NFR2, NFR35 ✓
**No data exfiltration:** NFR1 ✓
**Cross-platform:** NFR9, FR45 ✓

**Assessment:** Pass — all relevant domain constraints properly documented.

## Holistic Quality Validation

**Overall PRD Maturity:** Very high — this PRD has been through multiple validation and edit cycles with a deep edit history spanning from 2026-03-05 to 2026-04-07.

**Strengths:**
- Exceptional information density — zero filler phrases across ~700 lines
- Strong user journey coverage (7 roles, all with capability-tagged summaries)
- Rich innovation section with genuine novel patterns
- NFR measurability is strong — nearly all NFRs have specific metrics and measurement methods
- Full SDLC traceability from brief → PRD → journeys → FRs → NFRs
- Consistent style and voice throughout

**Areas for Improvement:**
- 5 implementation leakage items in new Knowledge Graph FRs (see above)
- FR145-147 (JSON schemas with exact field names) sit at the PRD/Architecture boundary — intentional product design choices, but worth flagging for downstream architecture doc to reference them explicitly
- No SMART flags, but FR152/FR154 are the weakest new FRs

**Holistic Quality Rating:** 4/5 — Excellent, minor improvements available
