PRD-004: SEA™ Forge Delivery Pipeline

Type

Product Requirement Document - Platform / Functional

Priority

Critical

Status

Proposed

Purpose

The SEA™ Forge Delivery Pipeline provides a spec-to-generation compilation system that transforms authoritative specifications into deterministic, governed software artifacts without agents writing product code.

Its purpose is to:

• Eliminate semantic drift
• Enforce architectural invariants
• Enable parallel, agent-assisted delivery
• Ensure all production code is generated from canonical models

1. Problem Statement

Modern agentic development systems:

• Allow agents to patch code directly
• Obscure intent behind diffs
• Introduce silent architectural drift
• Do not scale governance or auditability

SEA™ Forge requires a pipeline where:

• Intent is explicit
• Meaning is canonical
• Structure is declared
• Code is reproducible

2. Goals & Non-Goals

Goals

1. Compile Specs → SEA™ DSL → AST → Manifest → Generator Inputs → Code
2. Enforce no-agent-writes-code invariant
3. Support wave-based, parallel TDD cycles
4. Enable deterministic regeneration
5. Integrate Nx generators and bespoke generators
6. Support CI drift detection

Non-Goals

• Handwritten application logic
• Runtime agent autonomy
• Ad-hoc code patching
• Direct agent interaction with product source files

3. Users & Stakeholders

4. Functional Requirements

FR-1: Specification Ingestion

• Accept ADR, PRD, SDS as immutable inputs
• Treat specs as authoritative intent

FR-2: Delivery Plan Generation

• Compile specs into structured plans:
  • Waves
  • TDD cycles
  • Dependency graph
  • Branch strategy
• Persist plans as artifacts

FR-3: Semantic Compilation

• Translate specs into SEA™ DSL
• Validate against:
  • Semantic Core
  • SEA™ DSL policies
  • CALM constraints
• Emit AST

Acceptance Criteria:

• Invalid semantics block downstream stages
• Semantic diffs are machine-generated

FR-4: Manifest Generation

• Map AST → Manifest
• Manifest MUST declare:
  • Architectural style (e.g., hexagonal)
  • Bounded context
  • Domain references
  • Generator bindings

FR-5: Generator Input Compilation

• Compile Manifest → Nx generator inputs or bespoke generator schemas
• Support multiple generator targets per manifest

FR-6: Code Generation

• Execute generators deterministically
• Generated code MUST be reproducible
• Generated directories are read-only

FR-7: Validation & CI Gates

Mandatory gates:

1. Semantic validation
2. Manifest schema validation
3. Generator execution
4. Test execution
5. Drift detection (regen == committed)

FR-8: Parallel Execution Model

• One git branch per TDD cycle
• Parallel execution allowed when dependencies permit
• Merge gated on upstream artifact consistency

FR-9: Remediation Workflow

• Findings must be resolved by:
  • DSL updates
  • Manifest updates
  • Generator fixes
• Patching generated code is prohibited

FR-10: Special-Case Overrides

• Allow manual code only for:
  • Generator implementation
  • Platform glue
  • Emergency hotfix
• Require override record + backfill task

5. Non-Functional Requirements

6. Success Metrics

• % of changes driven by DSL/manifests
• Zero direct patches to generated code
• CI drift violations caught pre-merge
• Reduced merge conflicts in parallel cycles

7. Risks & Mitigations

8. Out of Scope

• Runtime AI autonomy
• Manual domain logic authoring
• Non-deterministic generation
