# Specification Quality Checklist: Progressive Streaming Emission

**Purpose**: Validate specification completeness and quality before proceeding to planning
**Created**: 2026-07-27
**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

- Backend names (whisper, nemotron, Parakeet-class, sherpa-onnx) appear in the spec
  because they *are* the subject matter — the feature is explicitly a per-backend
  plumbing + packaging effort across named inference snaps (same convention as feature
  007 naming the IE115 dialect). No code structure, class design, or implementation
  sequence is prescribed; strategy internals stay behind the adapter seam.
- Zero [NEEDS CLARIFICATION] markers: strategy set, default strategy, model defaults,
  and scope exclusions were all fixed by reasonable defaults recorded in Assumptions.
- Validation iteration 1 (2026-07-27): all items pass.
- Validation iteration 2 (2026-07-27, post-clarify): all items still pass. Scope
  tightened — the external WhisperLive-driver story/FR/SC was removed (recorded in
  spec Clarifications §2026-07-27); tail-mutation subsumes that algorithm in-adapter.
  FR numbering re-sequenced FR-001–FR-014, SC-001–SC-007; no requirement weakened.
