 | **Specification** | The **technical contract** — precise rules for inputs, outputs, and data shape. Ensures consistency across dev and test. | Developers, QA Engineers, CI/CD pipelines | OpenAPI, Protobuf, AsyncAPI. Endpoint definitions, schemas, error codes. | `contract.yaml` defining a NATS subject that accepts Arrow streams with snake_case headers. | 100% of messages validated against spec (CI block rate). |
 | **UI Specification** | The **design contract** — precise rules for UI components, interactions, and visual patterns. Ensures consistency across design and implementation. | Product Designers, Frontend Developers, QA Engineers | Component libraries, style guides, interaction specs, design tokens. | Atomic design system with Figma tokens synced to CSS variables. | 100% of UI components match design spec (visual regression tests). |
 | **Walkthrough** | The **end-to-end trace** — maps the entire system flow from startup to cycle completion. Provides a "big picture" view that validates solution design before technical specification is locked. | Product Owners, Architects, Developers | End-to-end user journey, sequence diagrams, state machine diagrams. Explicitly links to specification.md and ui-specification.md. | "User logs in → selects wine → edits details → saves → backend validates against spec → UI updates with error states." | 100% of user journeys traced across all layers before implementation starts. |
-| **Implementation** | The **real code** — business logic, helpers, tests, configs. Where design becomes executable. | Developers, Code Reviewers | Source code, README.md, unit tests, setup scripts. | Julia function for matrix calculation + SvelteKit component rendering table. | >80% unit test coverage, <5% drift from spec. |
+| **Implementation Plan** | The **execution roadmap** — how implementation is organized, prioritized, and delivered. Maps code to spec and validates against specification. | Developers, Project Managers, Lead Developers | Implementation plan, module breakdown, task list, delivery timeline, test strategy. | Phase 1: Core API + data layer; Phase 2: UI components; Phase 3: Integration tests + E2E validation. | 100% of specification sections mapped to implementation tasks, <10% timeline drift. |
 | **Validation** | The **enforcer** — ensures implementation matches the spec. Blocks drift and human error. | Automation servers, QA, Lead Developers | CI jobs, contract tests, linting, integration checks. | CI job rejects PR with camelCase field not allowed by YAML spec. | <1% of PRs bypass validation gates. |
 | **Runbook** | The **operational manual** — how the system lives in production, scales, and recovers. Guides on-call engineers. | DevOps, SREs, On-call Developers | K8s manifests, Helm charts, Markdown guides. Deployment, scaling, backup/restore, troubleshooting. | GitOps manifest ensuring 6 Julia replicas restart if memory >80%. | MTTR <15 minutes for P1 incidents. |

-**Purpose**: The *real code* — business logic, helpers, tests, configs. Where design becomes executable.
 
 **Why It Matters**:
-- This is the actual artifact that runs in production
+- Converts specification into executable code with clear ownership and timeline
-- Code is the ultimate source of truth (when it matches spec)
+- Enables parallel development across teams by defining module boundaries
-- Tests validate correctness and prevent regressions
+- Provides visibility into progress and blockers for stakeholders
-- Configuration files define runtime behavior
+- Ensures all specification sections are covered by implementation tasks
 
 **Content Guidelines**:
-- Business logic implementation
+- Implementation phases and timeline (e.g., Phase 1: Core API, Phase 2: UI, Phase 3: Validation)
-- Helper functions and utilities
+- Module/component breakdown with responsibilities and dependencies
-- Unit and integration tests
+- Task list with assignees, priorities, and estimated effort
-- Configuration files (YAML, JSON, environment)
+- Test strategy: which tests cover which specification sections (unit, integration, E2E)
-- Setup and development scripts
+- Build and deployment preparation (CI/CD setup, environment configuration)
-- Code organization and module structure
+- Risk mitigation: known blockers and mitigation steps
 
 **Best Practices**:
-- Follow consistent code style and conventions
+- Break implementation into small, testable increments (1-3 day sprints)
-- Write tests before or alongside implementation (TDD/BDD)
+- Map each implementation task to specific specification sections (not requirement IDs — those belong in specification.md)
-- Document complex logic with inline comments
+- Define clear ownership for each module or component
-- Keep configuration externalized and versioned
+- Include test coverage targets for each phase
-- Use type annotations where applicable
+- Document dependencies between modules to avoid blocking work
+- Review implementation plan against walkthrough to ensure complete coverage
