The `results.ts` version includes a comment: "duplicated here for schema locality". This is a deliberate choice — `results.ts` has no import from `enums.ts` for `Nullable`, opting for local definition. This avoids a circular or cross-module dependency for a trivial utility, which is reasonable. The test suite verifies that the re-export from `task.ts` is the same function object as from `enums.ts`. + +**Suggestion** (non-blocking): Consider importing `Nullable` from `enums.js` in `results.ts` instead of duplicating it. The `enums.ts` file already exports it, and `results.ts` already imports `TaskScopeEnum` etc. from `./enums.js`. This would ensure a single definition. However, the current approach is acceptable since the function is trivially one line and the duplication is explicitly documented. + +## Testing + +### Coverage Assessment + +- **Enum schemas**: All 6 enums tested with valid values, invalid values, null, and undefined. 30 tests ✅ +- **Nullable helper**: Tested with valid values, null, invalid values, undefined. 3 tests ✅ +- **TaskInput**: Comprehensive — minimal, full, null categorical, absent, invalid, wrong types, structured errors. 14 tests ✅ +- **DependencyEdge**: Minimal, with qualityRetention, boundary values, missing fields, wrong types, structured errors. 9 tests ✅ +- **Graph schemas**: NodeAttributes, NodeAttributesUpdate, EdgeAttributes, SerializedGraph factory — including verification that tags/assignee/due are not in the schema. 13+ tests ✅ +- **Result schemas**: RiskPathResult, DecomposeResult, WorkflowCostOptions, WorkflowCostResult, EvConfig, EvResult, RiskDistributionResult. All have valid, invalid, missing field, and wrong type tests. ~20 tests ✅ +- **Type alias correctness**: Compile-time type assertions alongside runtime checks for all enums and schemas ✅ +- **Error classes**: All 6 classes tested for instanceof chain, name, field access, and message formatting. 31 tests ✅ +- **defaults.ts**: All numeric functions tested with explicit value mapping. `resolveDefaults` tested with all-defaults, explicit values, label-only preservation, and mixed scenarios. 30 tests ✅ +- **riskWeight invariant**: Explicitly tested that `riskWeight(r) === 1 - riskSuccessProbability(r)` for all risk values ✅ + +### Edge Cases Tested + +- Nullable re-export identity (`NullableFromTask === Nullable`) ✅ +- `fromTypeBoxError` handles paths with and without leading `/` ✅ +- SerializedGraph has no version field ✅ +- SerializedGraph rejects wrong `options` values (undirected, multi, allowSelfLoops) ✅ +- `TaskGraphNodeAttributesUpdate` accepts empty object ✅ +- Prototype chain correctness for all error subclasses ✅ + +## Security + +- No secrets in code ✅ +- No input validation concerns at this layer (schemas are definitions, not runtime input paths) ✅ +- Supply chain check: no Zod, no gray-matter, no js-yaml ✅ + +## Performance + +- Numeric functions are simple `Record<>` lookups — O(1) ✅ +- No unnecessary allocations ✅ +- `resolveDefaults` is a pure function with no loop — optimal ✅ + +## Suggestions + +1. **(Low priority)** Consider importing `Nullable` from `./enums.js` in `results.ts` instead of duplicating the one-liner. Since `results.ts` already imports `TaskScopeEnum` etc. from `./enums.js`, adding `Nullable` to that import would reduce duplication without introducing new coupling. This is a minor style preference and not a correctness issue. + +## Recommendations + +1. ✅ All acceptance criteria are met. Implementation is approved. +2. Consider the `Nullable` import consolidation as a future cleanup (non-blocking). +3. The resolvedDefaults defaults match the architecture spec (`graph-model.md`): risk→"medium", scope→"narrow", impact→"isolated". Any future changes to these defaults should be reflected in both `defaults.ts` and `graph-model.md`. \ No newline at end of file
