Initial commit — design docs + Phase 0 validation harness

Sets up the Socrata project repo with:

docs/ — strategy and design documents
  - idea.md: full product vision
  - implementation-plan.md: Phase 0 + Phase 1 MVP plan
  - phase-0-validation.md: 2-week validation experiment strategy
  - phase-0-plan.md: concrete Phase 0 build plan
  - phase-0-results.md: Phase 0 gate outcome — GO for MVP
  - sysml-modeling.md: metamodel + SE discipline + validation rules
  - socrates.md: agent character, surfaces, modes, prompts, lifecycle
  - sync.md: bidirectional text↔diagram sync engineering
  - design-source/: HTML/CSS/JS handoff bundle from Claude Design

phase-0/ — validated harness (CLI, no UI, no DB)
  - LM Studio (local OpenAI-compatible) generation + detection + judge
  - PlantUML rendering for SysML model visualization
  - 10-seed corpus (8 working + 2 holdouts)
  - 5 corpus runs with iteration history in reports/
  - Final gate: 10/10 pass, mean 4.32/5, holdouts validated

Phase 1 MVP scope and milestones documented in implementation-plan.md.
