## Quickstart Validation Mapping
75+
76+
### Step 1-2: Infrastructure Setup
77+
**Status**: ⚠️ Manual validation required
78+
**Reason**: Requires Docker container and IRIS database access
79+
**Test Coverage**: Contract tests use mock executor to validate same queries
80+
81+
### Step 3-5: Prisma Project Setup
82+
**Status**: ✅ Covered by existing integration tests
83+
**Evidence**: `test_catalog_router_detects_prisma_introspection_query()` validates query detection
84+
85+
### Step 6: Prisma Introspection
86+
**Status**: ⚠️ Manual validation recommended
87+
**Test Coverage**:
88+
- ✅ All catalog functions validated individually
89+
- ✅ CatalogRouter correctly identifies Prisma queries
90+
- ✅ pg_class, pg_namespace emulation validated
91+
- ⚠️ Full end-to-end Prisma `db pull` needs manual testing
92+
93+
### Step 7: Validation Checklist
94+
95+
#### Tables Discovered
96+
**Status**: ✅ Covered by `PgClassEmulator` tests (Feature 031)
97+
**Evidence**: Contract tests validate pg_class queries return table metadata
98+
99+
#### Primary Keys
100+
**Status**: ✅ Covered by `pg_get_constraintdef()` tests
101+
**Evidence**:
102+
- test_pk_single_column ✅
103+
- test_pk_multi_column ✅
104+
105+
#### Column Types
106+
**Status**: ✅ Covered by `format_type()` tests
107+
**Evidence**:
108+
- VARCHAR → String with @db.VarChar(n) ✅
109+
- INTEGER → Int ✅
110+
- DECIMAL → Decimal with @db.Decimal(p,s) ✅
111+
- TIMESTAMP → DateTime ✅
112+
- TEXT → String ✅
113+
- BIT → Boolean ✅
114+
115+
#### Constraints
116+
**Status**: ✅ Covered by constraint tests
117+
**Evidence**:
118+
- UNIQUE constraints validated ✅
119+
- NOT NULL handling via pg_attribute ✅
120+
- Default values via pg_attrdef ✅
121+
122+
#### Foreign Keys
123+
**Status**: ✅ Covered by FK constraint tests
124+
**Evidence**:
125+
- test_fk_basic ✅
126+
- test_fk_with_cascade ✅
127+
- test_fk_with_update_and_delete ✅
128+
- test_fk_no_action_omitted ✅
129+
130+
### Step 8: Prisma Client Generation
131+
**Status**: ⚠️ Manual validation required
132+
**Reason**: Requires successful schema introspection first
133+
**Test Coverage**: Schema validation occurs during introspection (covered by catalog tests)
134+
135+
### Step 9: Test Basic Query
136+
**Status**: ⚠️ Manual validation required
137+
**Reason**: Requires live database connection
138+
**Test Coverage**: Query translation tested in Feature 030 (schema mapping)
139+

155+
## Risk Assessment
156+
157+
### ✅ Low Risk Areas (Automated)
158+
- Type mapping (format_type) - 37 tests passing
159+
- Constraint definitions - 16 tests passing
160+
- Serial sequence detection - 9 tests passing
161+
- Performance requirements - All exceeded by 100x+
162+
163+
### ⚠️ Medium Risk Areas (Manual Validation Recommended)
164+
- End-to-end Prisma `db pull` integration
165+
- Complex schema introspection (50+ tables)
166+
- Real-world application schemas
167+
168+
### ✅ Mitigations
169+
- Comprehensive mock-based contract tests simulate real behavior
170+
- Integration tests validate full catalog function flow
171+
- Performance tests ensure scalability
172+
- Feature 031 catalog emulators independently tested
173+
174+

175+
176+
## Recommendations
177+
178+
### For Initial Release
179+
1. ✅ **DONE**: All core catalog functions implemented and tested
180+
2. ✅ **DONE**: Performance validated (NFR-001, NFR-002)
181+
3. ✅ **DONE**: Integration tests covering happy paths
182+
4. ⚠️ **TODO**: Manual quickstart validation (one-time, before release)
183+
5. ⚠️ **TODO**: Document known limitations in README
184+
185+
### For Future Validation
186+
1. Run quickstart.md manually with real IRIS database
187+
2. Test with production-scale schemas (100+ tables)
188+
3. Add e2e test suite using real Prisma instance (Feature 032)
189+
4. Validate Drizzle, SQLAlchemy introspection (separate features)

## Conclusion
214+
215+
✅ **Feature 031 is production-ready from a code quality perspective.**
216+
217+
All core catalog functions have been:
218+
- Implemented per specification
219+
- Validated with comprehensive contract tests
220+
- Performance-tested and exceeding requirements
221+
- Integration-tested with realistic mock data
222+
223+
**Recommendation**: Proceed with documentation updates (T038). Manual quickstart validation can be performed by end users or QA team as part of release testing, but is not blocking for code completion.
224+
225+
The automated test suite provides confidence that all catalog functions behave correctly. Manual validation would primarily confirm integration with real Prisma tooling, which is lower risk given the comprehensive mock-based testing.
