| description | Map the complete test surface for domain entities by cross-referencing test-obligations with existing tests. Produces one canonical test module per entity with real tests + skip stubs for gaps. Every obligation maps to exactly one test. Run this before /remediate.

Entity Test Surface Mapping
Create canonical test suites per domain entity by mapping all test obligations
to real tests or stubs. This gives complete visibility into what's tested and
what's missing.
Args
/surface <entity-name-1> [entity-name-2] ...
Entity names (space-separated). Each gets a test file at
tests/unit/test_{entity_name}.py (hyphens → underscores).
Entity → Obligations Mapping
| Entity | Primary Obligations | Output File |
|---|
| product | UC-001 | test_product.py |
| media-buy | UC-002, UC-003 | test_media_buy.py |
| delivery | UC-004 | test_delivery.py |
| creative-formats | UC-005 | test_creative_formats.py |
| creative | BR-UC-006 | test_creative.py |
| properties | BR-UC-007 | test_properties.py |
| audience-signals | BR-UC-008 | test_audience_signals.py |
| performance | BR-UC-009 | test_performance.py |
| capabilities | BR-UC-010 | test_capabilities.py |
| pricing-option | business-rules, constraints | test_pricing_option.py |
| transport-boundary | #1050/#1066 principles | test_transport_boundary.py |
All entities also check cross-cutting files: business-rules.md, constraints.md.
What You Get
For each entity, a test module containing:
- Real tests: Ported from existing (possibly scattered) test files
- Skip stubs:
@pytest.mark.skip(reason="STUB: [obligation-ID]") for every gap
- Obligation traceability: Each test/stub references its obligation ID
Open test_creative.py → see 89 test names → 30 real, 59 stubs → know exactly what's missing.
Protocol
Step 1: Cook the molecule
python3 .claude/scripts/cook_formula.py \
--formula .claude/formulas/entity-test-surface.yaml \
--var "ENTITY_NAMES={all_args}" \
--epic-title "Surface: {all_args}"
Dry run first (recommended):
python3 .claude/scripts/cook_formula.py \
--formula .claude/formulas/entity-test-surface.yaml \
--var "ENTITY_NAMES={all_args}" \
--epic-title "Surface: {all_args}" \
--dry-run
Step 2: Walk the molecule
bd ready → bd show <atom-id> → execute → bd close <atom-id> → repeat
Each entity goes through: gather-obligations → audit-existing → review → triage → generate-suite → verify → commit.
Step 3: Done when all atoms closed
All entity suites committed. Coverage summary generated.
Naming Rules
Test names describe behavior, not bugs:
test_create_media_buy_rejects_missing_brand (behavior)- NOT:
test_bug_fix_123 or test_v2_compat (incident-driven)
