# {{Project Name}} — Master Plan

> Master design document for a phased-execution project. The phase roadmap
> below was derived from `{{TODO file}}` on {{date}}; each phase overview and
> task file cites its source lines in that file. The **LOCKED DECISIONS**
> below are binding: no phase may introduce technology outside them without
> explicit user permission.

## Assumptions & Design Principles
- {{...}}

## Architectural Anchors
| COMPONENT | DECISION | RATIONALE | STATUS |
|-----------|----------|-----------|--------|
| {{component}} | {{decision — inherited from the existing codebase}} | {{why}} | LOCKED |
| {{component}} | {{decision awaiting ratification}} | {{why}} | PROPOSED |

## High-Level Architecture
{{Component breakdown and data flow, mirroring the actual code.}}

## Data Model
{{Existing schemas, state transitions, and persistence details.}}

## Validation / Verification Workflow
{{Multi-step logic ensuring high-confidence outputs (unit → integration →
contract/E2E → coverage floor).}}

## Phase Roadmap
| # | Phase | TODO source | Objective (one line) |
|---|-------|-------------|----------------------|
| 01 | {{NN_name}} | — | foundation: adapt validate.sh, green test baseline (where applicable) |
| 02 | {{NN_name}} | `{{TODO file}} L{{a}}–L{{b}}` | {{...}} |
