description	Use when verifying acceptance criteria. Binary verdict per criterion. Evidence-based.

Acceptance Criteria Validation

When to Use

∀ verification ∧ acceptance testing. ∀ spec validation.

HARD-GATE

∀ criterion: verdict is PASS ∨ FAIL. ¬"partially met". ¬"close enough". Binary.

Verification Process

∀ acceptance criterion ∈ SPEC.md:

1. READ: Find the implementation that satisfies this criterion
2. RUN: Execute the test/command that proves it works
3. EVIDENCE: Record exact output (¬"should work", ¬"probably passes")
4. VERDICT: PASS (evidence proves it) ∨ FAIL (evidence disproves it ∨ missing)

Output Format

AC	Verdict	Evidence
AC1: User can login	PASS	npm test -- auth.spec.ts -> 4/4 passing
AC2: Rate limit at 100/min	FAIL	No rate limit test ∃

Spec Validation (Discuss Phase)

∀ criterion must be:

• Testable: Can write a test for it
• Binary: Unambiguous pass/fail
• Scoped: ∈ this scope (¬future work)
• Independent: ¬depends on unimplemented criteria from other scopes

Anti-Patterns

• "Close enough" (binary: met ∨ ¬met)
• Trusting agent reports without running commands
• Testing implementation details instead of user-visible behavior
• Accepting criteria that aren't testable

Rules

• Evidence before claims, always
• If you didn't run the command ∈ this session, you cannot claim it passes
• ∀ FAIL: explain what's missing + what would make it PASS
• intent > letter — meets ∧ misses point -> FAIL
