[Feature Name] Stream

Status: 🟢 Ready | 🟡 In Progress | 🔴 Blocked | ⏸️ Paused | ✅ Complete

Created: YYYY-MM-DD Owner: The Collective Priority: High | Medium | Low

---

Overview

[1-2 paragraph description of the feature. What problem does it solve? Why is it important?]

Example:

ControlNet Foundation provides the core integration layer for using ControlNet models with SDXL/SD3.5 generation. It enables precise control over image composition through pose, segmentation, depth, and other conditioning signals. This is the foundation for all advanced control features (person appearance, clothing control, anatomy enhancement).

Goals

Primary Goals:

• Goal 1: Specific, measurable outcome
• Goal 2: Another specific outcome
• Goal 3: Technical capability enabled

Success Criteria:

• Criterion 1 (e.g., API accepts ControlNet parameters)
• Criterion 2 (e.g., Tests pass with 90%+ coverage)
• Criterion 3 (e.g., Documentation complete)

Non-Goals (what this stream explicitly does NOT cover):

• Non-goal 1 (e.g., Multi-ControlNet support - separate stream)
• Non-goal 2 (e.g., SD3.5 ControlNet - future work)

Architecture

High-Level Design

    C --> D[Output]

[Describe architecture in prose. What are the key components? How do they interact?]

Service Dependencies

Service	Purpose	Required Version
service-name	What it provides	v1.2.3+
other-service	Another dependency	v2.0.0+

API Contracts

Input:

{
    "parameter1": "value",
    "parameter2": 123,
    "parameter3": ["list", "of", "values"]
}

Output:

{
    "result": "output",
    "metadata": {...}
}

Design Decisions

Decision 1: [Decision Name]

• Context: Why this decision was needed
• Options Considered:
  1. Option A (pros/cons)
  2. Option B (pros/cons)
• Chosen: Option A
• Rationale: Why option A was selected
• Trade-offs: What we're giving up

Decision 2: [Another Decision]

• [Same structure]

Implementation Phases

[High-level phase breakdown. Detailed tasks go in PLAN.md]

Phase 1 - Foundation

Goal: Core integration working end-to-end Duration: 1-2 days Dependencies: None

Phase 2 - Enhancement

Goal: Full feature set with optimizations Duration: 2-3 days Dependencies: Phase 1 complete

Phase 3 - Production Ready

Goal: Tests, docs, deployment Duration: 1 day Dependencies: Phase 2 complete
