# Specification Quality Checklist: SymForge v8 Phase 2 STEL Controller Maturity

**Purpose**: Validate specification completeness and quality before proceeding to `/speckit-tasks` and implementation

**Created**: 2026-06-14

**Feature**: [spec.md](../spec.md)

## Content Quality

- [x] No premature implementation details beyond binding STEL/gate vocabulary
- [x] Focused on controller maturity and measurable gate exit
- [x] Written for reviewers and release owners
- [x] All mandatory sections completed

## Requirement Completeness

- [x] No [NEEDS CLARIFICATION] markers remain
- [x] Requirements are testable and unambiguous
- [x] Success criteria are measurable (H3/H4/H5, golden 36/36, A-029)
- [x] Success criteria reference binding gate vocabulary intentionally
- [x] All acceptance scenarios defined for five user stories
- [x] Edge cases identified
- [x] Scope clearly bounded (persistence, B-RESULTS excluded)
- [x] Dependencies and assumptions identified (Phase 1 baseline, A-008..A-014, A-029)

## Feature Readiness

- [x] Functional requirements map to success criteria
- [x] User scenarios cover multi-hop, L2, battery, spike, boundaries
- [x] Phase 3 / post-8.0 exclusions explicit
- [x] Recommended implementation slices ordered by risk

## Phase Boundary Checks

- [x] Calibration persistence excluded from Phase 2
- [x] B-RESULTS / §8.7 excluded from Phase 2
- [x] Phase 1 guarded apply semantics preserved
- [x] Compact-3 surface count unchanged without pivot evidence

## Notes

- Spec approval is planning gate only; no `src/stel/` changes until `/speckit-tasks` and milestone branch opened.
- Battery commands in quickstart are template paths — operator must pin sf-bench location in gate report.
- Independent reviewer sign-off for Phase 2 exit should follow same discipline as Phase 0 (producer ≠ sole approver for gate PASS claims).
