Acceptance Review Criteria

Overview

Formal gate definitions and verdict rubric for the acceptance-designer-reviewer. Applied across 4 lenses (coverage, business-alignment, testability, boundary-enforcement).

---

Gate Definitions (G1–G8)

Lens 1: coverage-lens

Gate	ID	Definition	Pass condition	Fail severity
AC–Scenario bijection	G1	Every AC in ac-draft-{story}.md maps to ≥1 scenario. No scenario exists without a traceable AC.	All ACs covered, no orphan scenarios.	BLOCKER
Edge case representation	G2	Boundary conditions and negative cases from the domain examples in the story are represented as scenarios.	≥1 edge case or boundary condition scenario per business rule.	HIGH

Checking G1:

1. List all ACs from ac-draft-{story}.md
2. List all scenarios from *.feature
3. Build a trace matrix: AC → scenario(s)
4. Flag any AC with no scenario (missing) and any scenario with no AC (orphan)

---

Lens 2: business-alignment-lens

Gate	ID	Definition	Pass condition	Fail severity
Business vocabulary	G3	All nouns, verbs, and adjectives in Given/When/Then steps appear in the domain vocabulary of the stories or the business lexicon. No class names, method names, HTTP verbs, or framework names.	Zero technical identifiers in .feature files.	HIGH
No technical jargon	G4	Given/When/Then steps contain zero implementation details: no HTTP status codes, no ORM terms, no database language, no DI container references.	Zero implementation leaks.	BLOCKER

G4 red flags (auto-fail):

• POST, GET, HTTP 200, HTTP 422
• Repository, Service, Handler, Controller, UseCase
• null, true, false as business values (unless they are genuine domain terms)
• SQL, JSON, XML, YAML in scenario text
• Class names (Pascal case identifiers)

---

Lens 3: testability-lens

Gate	ID	Definition	Pass condition	Fail severity
Step unambiguity	G5	Every step can be implemented without asking the designer for clarification. The step's meaning is unambiguous within the domain vocabulary.	Every step maps uniquely to a domain action or state.	HIGH
Implementation plan completeness	G6	Every scenario listed in the .feature files has a corresponding entry in impl-plan-{story}.md with a file path and a use case boundary.	Bijection feature scenarios ↔ impl-plan entries.	HIGH

Checking G5: For each step, ask "could two engineers implement this differently and both be correct?" If yes, the step is ambiguous.

---

Lens 4: boundary-enforcement-lens

Gate	ID	Definition	Pass condition	Fail severity
Layer boundary compliance	G7	Each row in the coverage matrix targets an Application layer use case named in contracts-{story}.md. No scenario targets an Infrastructure adapter directly as its primary entry point.	All coverage matrix entries reference a use case boundary from the contracts.	BLOCKER
Walking skeleton coverage	G8	At least one walking skeleton scenario per major feature flow is identified in the test plan (tagged @smoke or marked Walking Skeleton in the matrix).	≥1 walking skeleton entry per feature flow.	HIGH

---

Severity Definitions

Severity	Definition	Impact
BLOCKER	Fundamental correctness violation. The artefact cannot be used by DELIVER as-is.	Always triggers rejected verdict.
HIGH	Significant quality gap. Increases implementation risk or causes rework in DELIVER.	Triggers changes_requested unless no other severity exists.
MEDIUM	Quality improvement. Can be implemented but suboptimal.	Triggers changes_requested.
LOW	Style or consistency issue. Does not affect DELIVER.	approved with recommendation.

---

Verdict Derivation

Condition	Verdict
≥1 BLOCKER in ANY lens	rejected
≥1 HIGH, 0 BLOCKER (across ALL lenses)	changes_requested
MEDIUM only (across ALL lenses)	changes_requested
LOW only, or all lenses pass	approved

Confidence:

• high — all artefacts present, clear findings, no ambiguity
• medium — some artefacts missing, or findings require interpretation
• low — critical artefacts missing, review is incomplete

---

Dissent Handling

When 3 lenses pass and 1 fails:

1. Document the minority finding explicitly in dissent
2. Assess whether the minority finding independently triggers BLOCKER/HIGH severity
3. If BLOCKER/HIGH → uphold the minority. Verdict = changes_requested or rejected.
4. If MEDIUM/LOW → override the minority. Verdict = approved with recommendation.
5. NEVER silently override. Document the reasoning.

Example dissent entry:

dissent: "business-alignment-lens flagged 'driver ID' in step text (G3 HIGH).
Overridden: 'driver ID' is a genuine domain term used consistently in the story
vocabulary. Not a technical identifier. Verdict remains approved."

---

Scoring Rubric (per lens)

Score	Meaning
pass	All gates in this lens pass. No findings.
fail	≥1 gate in this lens has a finding.

Each finding includes:

• gate — G1 through G8
• severity — BLOCKER / HIGH / MEDIUM / LOW
• finding — plain-language description of the problem
• location — file path and line/scenario reference
• suggestion — (optional) how to fix it
