- Migration 007: repo_url on apps table + analysis table with FTS5 - Analysis struct, parser, CRUD, validation, hash computation - Selective purge: remote-only apps/analysis preserved across fn index - CLI: fn app list/clone/pull, fn analysis list/clone/pull - search/show/list now include analysis results - Apps removed from git tracking (content lives in Gitea repos) - .gitkeep for apps/ and analysis/ dirs - Bash functions: jupyter analysis pipeline, shell utilities - Browser domain: CDP functions moved from infra to browser Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
