description	Conduct a "Day 0" interview with the founder to populate the project's domain-knowledge.md and CONTEXT.md. Use when the agent encounters an undocumented Black Box.

LFE Domain Extraction (Day 0)

Position in Pipeline

• Phase: Any (Failure Recovery)
• Persona: Architect
• Trigger: Called when any persona encounters an undocumented "Black Box" in the code, or at project initialization
• Output: .docs/domain/domain-knowledge.md + CONTEXT.md

Mission

Extract the project's core logic, math, and terminology from the founder's mind and formalize it into the Library System.

Workflow

1. The Core Entity: Ask "What is the single most important noun in this project? What is its exact definition?"
2. The Golden Logic: Ask "What is the 'Golden Rule' or primary calculation that this project performs? Walk me through the logic step-by-step."
3. The Constraints: Ask "What are the project's absolute hard constraints (legal, safety, or architectural) — the rules that must always hold?"
4. The Vocabulary: Identify synonyms or ambiguous terms used during the interview and map them to canonical terms.

Output

Produce a draft for:

• .docs/domain/domain-knowledge.md
• CONTEXT.md — using the format defined in CONTEXT-FORMAT.md

Rules

• Follow the CONTEXT-FORMAT.md standard for all glossary entries (one-sentence definitions, Avoid aliases, relationships, example dialogue).
• If CONTEXT.md already exists, merge new terms into it rather than overwriting.
• If an ADR is warranted by a decision made during extraction, use the format in ADR-FORMAT.md.
• After extraction, update pipeline_status.md to reflect the new domain knowledge.
