v0.19.0 — 4+5+3 Architecture: Skill Pack Refinement, Memory-Soul Bridge & Meta-skill Overhaul

What's New in v0.19.0

P24 — Skill Pack Refinement

• openpersona refine <slug> — AI-driven iterative refinement of the behavior guide (soul/behavior-guide.md) against the constitutional compliance gate
• New lib/lifecycle/refine.js pipeline: scanConstitutionKeywords, loadMeta/writeMeta, bumpRevision, bootstrapBehaviorGuide, emitRefinement, applyRefinement
• Pack revision tracking via meta.packRevision; fork inherits parentPackRevision when available

P1 — Memory as Soul Infrastructure

• memory.js supersession chain: new memory entries mark superseded ones; retrieve/search/stats exclude superseded entries
• promoteToInstinct: groups recurring eventLog patterns (interest_discovery / trait_emergence / mood_shift) into evolvedTraits; gated by immutableTraits; idempotent
• Fork memory inheritance: copy policy clones memories.jsonl to child; none policy leaves child clean
• openpersona state promote <slug> [--dry-run] — Soul-Memory Bridge CLI command

Architecture Documentation Overhaul

• skills/open-persona/SKILL.md restructured around the 4+5+3 model (4 Layers · 5 Systemic Concepts · 3 Gates)
• ## Systemic Concepts section with dedicated subsections for Evolution, Economy, Vitality, Social, Rhythm
• ## Creating a Persona reorganized into 4 explicit layer subsections: Soul / Body / Faculty / Skill
• New ## Trust & safety reviewer summary for marketplace security audits
• References split into ARCHITECTURE.md, EVOLUTION.md, ECONOMY.md, FACULTIES.md, AVATAR.md, HEARTBEAT.md, PRESETS.md

CLI Additions

• openpersona refine <slug> — skill pack behavior guide refinement
• openpersona canvas <slug> — Living Canvas promoted to top-level command (was vitality canvas)

Dependency Updates

• agentbooks bumped to ^0.1.4

Framework Version

All version references unified at 0.19.0 across package.json, SKILL.md, lib/registry, lib/report/vitality-report.js, and demo/generate.js.
