ADDED Requirements

Requirement: Phase 1.5 checks cross-artifact alignment explicitly

SM Flow SHALL explicitly check alignment across requirement, design, specification, and execution artifacts during Phase 1.5.

Scenario: Alignment check runs

• WHEN Phase 1.5 reviews the current Draft OpenSpec
• THEN it checks that brief/prd aligns with proposal, proposal aligns with design, design aligns with specs, and specs align with tasks

Scenario: Alignment gap is found

• WHEN an expected behavior, term, field, constraint, or implementation slice appears in one artifact but not its downstream artifact
• THEN the flow marks the gap explicitly and repairs OpenSpec before entering the next phase

Requirement: Phase 2.9 validates cross-artifact closure

SM Flow SHALL re-check cross-artifact closure during Phase 2.9 before implementation.

Scenario: Commit gate runs

• WHEN Phase 2.9 evaluates whether Draft OpenSpec can become Committed OpenSpec
• THEN it verifies that evidence.md and decisions.md findings that affect implementation are reflected in proposal, design, specs, or tasks

Scenario: User review would otherwise catch the gap

• WHEN a field, scope item, acceptance behavior, or design constraint is missing from the downstream OpenSpec artifacts
• THEN the flow SHALL fail the commit gate and return to the earlier phase that owns the missing update
