Memento-based undo/redo with full encounter snapshots. Undo stack capped at 50 entries, persisted to localStorage. Triggered via buttons in the top bar (inboard of turn navigation) and keyboard shortcuts (Ctrl+Z / Ctrl+Shift+Z, Cmd on Mac, case-insensitive key matching). Clear encounter resets both stacks.

# Specification Quality Checklist: Undo/Redo
|
|
|
|
**Purpose**: Validate specification completeness and quality before proceeding to planning
|
|
**Created**: 2026-03-26
|
|
**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. The spec references "memento pattern" and "localStorage" — these are architectural intent from the issue itself, not implementation leakage. The spec describes *what* (snapshot-based history, persisted to local storage) not *how* (no code structure, no framework APIs).
|
|
- The "Assumptions" section documents the localStorage sizing assumption and the dependency on #15 being resolved.
