Independent feature against main. detect_index_redundancy(snapshot) flags exact duplicates (warning; keeps the unique one) and prefix-shadowed indexes (info; (a) shadowed by (a,b)). Unique indexes never suggested for dropping (constraints); expression/partial indexes skipped rather than guessed (false negatives over false positives). GET /api/snapshots/{uuid}/index-redundancy, IDOR-safe. +4 tests.

main.GET /index-redundancyfinds safe index-drop candidates: exact duplicates (warning — keeps the unique one) and prefix-shadowed indexes (info —(a)covered by(a, b)). Every index costs write amplification; these are free wins. Unique indexes are never suggested for dropping (they enforce constraints); expression/partial indexes are skipped rather than guessed. Pure, IDOR-safe. backend +4 tests; mypy clean.🤖 Generated with Claude Code
