Implement the 029-on-demand-bestiary feature that replaces the bundled XMM bestiary JSON with a compact search index (~350KB) and on-demand source loading, where users explicitly provide a URL or upload a JSON file to fetch full stat block data per source, which is then normalized and cached in IndexedDB (with in-memory fallback) so creature stat blocks load instantly on subsequent visits while keeping the app bundle small and never auto-fetching copyrighted content

+# Specification Quality Checklist: On-Demand Bestiary with Pre-Indexed Search
+
+**Purpose**: Validate specification completeness and quality before proceeding to planning
+**Created**: 2026-03-10
+**Feature**: [spec.md](../spec.md)
+
+## Content Quality
+
+- [x] No implementation details (languages, frameworks, APIs)
+- [x] Focused on user value and business needs
+- [x] Written for non-technical stakeholders
+- [x] All mandatory sections completed
+
+## Requirement Completeness
+
+- [x] No [NEEDS CLARIFICATION] markers remain
+- [x] Requirements are testable and unambiguous
+- [x] Success criteria are measurable
+- [x] Success criteria are technology-agnostic (no implementation details)
+- [x] All acceptance scenarios are defined
+- [x] Edge cases are identified
+- [x] Scope is clearly bounded
+- [x] Dependencies and assumptions identified
+
+## Feature Readiness
+
+- [x] All functional requirements have clear acceptance criteria
+- [x] User scenarios cover primary flows
+- [x] Feature meets measurable outcomes defined in Success Criteria
+- [x] No implementation details leak into specification
+
+## Notes
+
+- All items pass validation. Spec is ready for `/speckit.clarify` or `/speckit.plan`.
+- FR-009 originally mentioned "IndexedDB" explicitly; updated to technology-agnostic "client-side storage" language.
+- The spec covers 4 user stories with clear priority ordering: search (P1), stat block fetch (P2), file upload (P3), cache management (P4).
