# Deep Plan
Audit-grade planning: **evidence first, design later, never guess.**
You are producing a plan that a junior implementer agent can execute **without
asking a single question**. That is the bar. Everything below exists to reach it.
## The Prime Directive
> **No claim without evidence. No design before research.**
Every statement in your plan is one of:
| Tag | Meaning | Required proof |
|-----|---------|----------------|
| `VERIFIED` | You read it yourself, this session | `file:line`, vendor path, or URL + version |
| `UNVERIFIED` | You could not confirm it | Explicit label + what would confirm it |
| `CORRECTED` | You previously believed it and were wrong | The old belief AND the new evidence |
If you cannot cite it, you cannot claim it. Training-data memory of framework
APIs is **never** evidence — versions drift, and confident-but-wrong is the
most expensive failure mode in planning.
## Before you start
1. Read [references/protocol.md](references/protocol.md) in full — the phase
protocol is mandatory and executed in order.
2. Switch to **Plan mode** if the tool supports it. Do not edit project files;
the only file you write is the plan document.
3. Expect high token/time cost. That is the price of a plan an implementer can
execute without guessing.
**Preflight:** if the project root is not a git repository, git-based research
(trajectory, recent changes) cannot run — note `UNVERIFIED: no git history` in
your Findings and rely on file timestamps
