Architect: Propose Plan

Command: pasture:architect:propose-plan — Create PROPOSAL-N task with full technical plan

-> Full workflow in PROCESS.md <- Phase 3

[arch-propose-bdd-format]

• Given: feature request
• When: proposing
• Then: use BDD Given/When/Then format with acceptance criteria
• Should not: write vague requirements

[arch-propose-checklist-required]

• Given: plan
• When: creating task
• Then: include validation_checklist and tradeoffs in design field
• Should not: leave checklist empty

[arch-propose-revision-history]

• Given: existing plan
• When: revising
• Then: create PROPOSAL-N+1 task and mark old as pasture:superseded
• Should not: lose history

When to Use

Starting new feature design; creating formal plan for review.

PROPOSAL-N Naming

Proposals are numbered incrementally: PROPOSAL-1, PROPOSAL-2, etc. Each revision increments N. Old proposals are marked pasture:superseded with a comment explaining why.

Beads Task Creation

## Problem Space

**Axes of the problem:**
- Parallelism: ...

**Has-a / Is-a:**
- X HAS-A Y
- Z IS-A W

## Engineering Tradeoffs

| Option | Pros | Cons | Decision |
|--------|------|------|----------|
| A | ... | ... | Selected |
| B | ... | ... | Rejected |

## MVP Milestone

<scope with tradeoff rationale>

## Public Interfaces

\`\`\`go
type Example interface { /* ... */ }
\`\`\`

## Types & Enums

\`\`\`go
type ExampleType int

const (
    ExampleTypeA ExampleType = iota
    ExampleTypeB
)
\`\`\`

## Validation Checklist

# Link to request
bd dep add <request-id> --blocked-by <proposal-id>

Before Creating the Proposal

Read the URD and Phase 1 outputs to understand full context before drafting:

bd show <urd-id>
bd show <request-id>   # includes classification, research findings, explore findings as comments

The URD contains the structured requirements, priorities, design choices, and MVP goals from the URE survey. The REQUEST task comments contain Phase 1 outputs: classification (4 axes), domain research findings (prior art, standards), and codebase exploration findings (entry points, related types, dependencies). Your proposal must:

• Trace back to URD requirements
• Incorporate research findings (prior art, domain standards) into engineering tradeoffs
• Reference explore findings (entry points, existing patterns) in the files affected section

Plan Structure

• Requirements Traceability: URD: <urd-id>
• Problem Space (axes, has-a/is-a)
• Engineering Tradeoffs (table with decisions)
• MVP Milestone (scope with tradeoff rationale)
• Public Interfaces (Go)
• Types & Enums
• Validation Checklist (per phase)
• BDD Acceptance Criteria
• Files Affected

Next Steps

After creating PROPOSAL-N task:

1. Run /pasture:architect-request-review to spawn 3 reviewers
2. Wait for all 3 reviewers to vote ACCEPT
3. Run /pasture:architect-ratify to add ratify label to PROPOSAL-N

Follow-up Proposals (FOLLOWUP_PROPOSAL-N)

When creating proposals for a follow-up epic (received via h6 from supervisor):

• Title prefix: FOLLOWUP_PROPOSAL-N: (e.g., FOLLOWUP_PROPOSAL-1: Add request-id correlation)
• References: Include both original_urd: <id> and followup_urd: <id> in frontmatter
• Content: Address specific IMPORTANT/MINOR findings scoped in FOLLOWUP_URE/URD
• Same review/ratify/UAT lifecycle applies (3 reviewers, ACCEPT/REVISE, UAT, ratify, handoff)
