Specification Quality Checklist: Windows upgrade POSIX-mode fidelity

Purpose: Validate specification completeness and quality before proceeding to planning Created: 2026-09-22 Feature: spec.md

Content Quality

  • ✅ No implementation details leak into WHAT/WHY (call-sites named as scope anchors only, not as design)
  • ✅ Focused on user value and business needs (Windows user can upgrade; converged = trustworthy)
  • ✅ Written to be legible to non-technical stakeholders (summary + user stories)
  • ✅ All mandatory sections completed

Requirement Completeness

  • ✅ No [NEEDS CLARIFICATION] markers remain
  • ✅ Requirements are testable and unambiguous
  • ✅ Requirement types are separated (Functional / Non-Functional / Constraints)
  • ✅ IDs are unique across FR-###, NFR-###, and C-### entries
  • ✅ All requirement rows include a non-empty Status value
  • ✅ Non-functional requirements include measurable thresholds (100% green, 0 regressions, self-mutation proof)
  • ✅ Success criteria are measurable (0 crashes, 184→0 repairs, 0 regressions)
  • ✅ Success criteria are technology-agnostic (user-facing outcomes)
  • ✅ All acceptance scenarios are defined (Given/When/Then per story)
  • ✅ Edge cases are identified (symlink-on-Windows, genuine POSIX divergence, mixed batch)
  • ✅ Scope is clearly bounded (C-003 names out-of-scope #4925/#4783/#4928)
  • ✅ Dependencies and assumptions identified (Assumptions section)

Feature Readiness

  • ✅ All functional requirements have clear acceptance criteria
  • ✅ User scenarios cover primary flows (crash-free upgrade; converged reports zero)
  • ✅ Feature meets measurable outcomes defined in Success Criteria
  • ✅ No implementation details leak into specification

Notes

two-lens grounding squad (alignment + scope) against current main.

not-applicable row rather than a silent omission.

  • All items pass on the first iteration. Requirements are grounded in a completed
  • The #4925 defer is recorded as a Constraint (C-003) and an issue-matrix
