- schemas.md: Replace interface ResolvedTaskAttributes with TypeBox schema
+ Static<typeof> derivation (was the only raw interface in the doc set)
- schemas.md: Add explicit TypeBox naming convention table and pattern guide
- schemas.md: Use Nullable() helper for TaskInput optional categorical fields
that can be explicitly set to null in YAML
- schemas.md: Reference typebox-patterns.md research for full analysis
- api-surface.md: Add note about Static<typeof> pattern consistency
- errors-validation.md: Use Value.Errors() for structured validation instead
of bare Value.Check()
- New: docs/research/typebox-patterns.md — comprehensive TypeBox pattern
evaluation covering Static, Values, Convert, Pointer, TemplateLiteral,
generics, defaults, and concrete schema recommendations
The 751-line architecture.md violated the SDD process modular documentation
target (~500 lines). It also had duplicate TaskGraph class definitions (one
monolith, one decomposed) that directly contradicted each other, and embedded
consumer-specific tool dispatch mappings that belong in downstream projects.
Changes:
- Split into 8 focused documents + 7 ADR records + redirect page
- Removed the monolithic TaskGraph class (kept only decomposed version)
- Moved CLI→plugin dispatch mapping out (belongs in plugin architecture)
- Extracted implementation code (frontmatter splitter, findCycles, DAG
propagation) into WHAT/WHY descriptions per architect role spec
- Added proper ADR format for all resolved design decisions
- Fixed review issues: C_fail mapping, DuplicateNodeError/DuplicateEdgeError
types, ValidationError/GraphValidationError definitions, mutation error
handling contract, enum naming convention, validation timing clarification
