Extends the deterministic Personality Analysis profile with a second layer scored from the same effective-pattern facets: one score per Jungian cognitive function (Ni/Ne/Si/Se/Ti/Te/Fi/Fe), mapped 1:1 from the 8 effective-pattern categories, plus a pure deriveMbti() that picks a 4-letter type from the standard 16-type function-stack table using dominant/auxiliary scores with a documented, deterministic tie-break. PersonalityProfile.profileVersion bumps to 2 (cognitiveFunctions + mbti fields); PERSONALITY_ANALYSIS_VERSION bumps to 2.0.0. No SQLite schema change — personality_snapshots.results_json is an opaque JSON blob and old cached rows are read via JSON.parse(...) as PersonalityProfile, not runtime- validated, so profileVersion 1 stays in the type union for those. Every number here stays deterministic and LLM-free, same as the rest of this module — the archetype narrative continues to be the only LLM-touched field.
Extends the archetype-generation LLM call (POST /api/personality/generate) to also return a ranked top-5 MBTI type guess list with reasoning, grounded in the 8 cognitive function scores and 4 traits — a softer, LLM-authored companion view alongside the existing deterministic single-type derivation. `likelihood` is a deliberate, documented exception to this feature's "LLM never produces a number" rule, since ranking requires one. Every field is re-validated/clamped server-side (type must be one of the 16 valid codes, deduped, capped at 5, likelihood clamped to 0-100, rank reassigned from array order).

Summary
PersonalityProfile.profileVersionbumped to2;PERSONALITY_ANALYSIS_VERSIONbumped to2.0.0. No DB migration needed —personality_snapshots.results_jsonis an opaque JSON blob.CognitiveFunctionRadarChart(8-axis radar, mirrorsPersonalityRadarChart) andMbtiCard(type, confidence, function stack), wired intoPersonalityPage.server/src/schemas/personality.ts) updated to match.Test plan
cd cli && pnpm test— 914/914 passing, including new coverage for all 8 function scores, MBTI derivation (INTJ/INFJ/ESFP/ESTP fixtures), the <2-signal null case, and tie-break determinism.pnpm buildfrom repo root — zero TypeScript errors across cli/server/dashboard.pnpm testfrom repo root — cli 914, server 655, dashboard 15, all passing.🤖 Generated with Claude Code
