What problem does it solve? After upgrading a Lumina wiki package, existing entries often lack newly introduced frontmatter fields like provenance and confidence, causing lint errors and inconsistent metadata. This Skill detects those gaps and backfills them with evidence-based inferred values instead of blind defaults. ## Core Features & Use Cases - CHANGELOG-driven migration: Reads ### Migration sections in the CHANGELOG to determine exactly which fields each version introduced, so it works across versions without modification. - Evidence-based inference: Infers provenance from ingest checkpoints and raw file scans, and confidence from inbound citation counts, falling back to conservative values like unverified when evidence is ambiguous. - Verified, idempotent writes: Applies changes through atomic set-meta operations, re-runs lint to confirm zero errors, clears the manifest flag, and logs the migration. - Use Case: After upgrading a wiki to v0.9, run the migration to backfill provenance and confidence on dozens of legacy source entries, convert legacy url fields to urls arrays, and confirm a clean lint report. ## Quick Start Run /lumi-migrate-legacy to detect missing schema fields on legacy wiki entries and backfill them with inferred values.
