   - Recommendations export when owned-only deck is incomplete (~1.5× missing) to `deck_files/[stem]_recommendations.csv` and `.txt`
 - CSV export includes an `Owned` column when not using owned-only
 - Windows EXE build via PyInstaller is produced on tag and attached to GitHub Releases
+ - Prefer-owned option in Review: bias selection toward owned cards while allowing unowned fallback (stable reorder + gentle weight boosts applied across creatures and spells)
+ - Owned page enhancements: export TXT/CSV, sort controls, live "N shown," color identity dots, exact color-identity combo filters (incl. 4-color), viewport-filling list, and scrollbar styling
+ - Finished Decks: theme filters converted to a dropdown with shareable state
+ - Staged build: optional "Show skipped stages" toggle to surface stages that added no cards with a clear annotation
+ - Owned/Not-owned badges visible across views; consolidated CSS for consistent placement
+ - Visual summaries: Mana Curve, Color Pips and Sources charts with cross-highlighting to cards; tooltips show per-color card lists and include a Copy action
+ - Source detection: include non-land mana producers and colorless 'C'; basic lands reliably counted; fetch lands excluded as sources
+ - Favicon support: `/favicon.ico` served (ICO with PNG fallback)
+ - Diagnostics: `/healthz` endpoint returns `{status, version, uptime_seconds}`; responses carry `X-Request-ID`; unhandled errors return JSON with request_id
+ - Tooltip Copy action on chart tooltips (Pips/Sources) for quick sharing of per-color card lists
 
 ### Changed
 - Rename folder from `card_library` to `owned_cards` (env override: `OWNED_CARDS_DIR`; back-compat respected)

 - Release notes source is `RELEASE_NOTES_TEMPLATE.md`; `RELEASE_NOTES.md` ignored
 - README/DOCKER/WINDOWS_DOCKER_GUIDE updated for Web UI, headless examples, and PowerShell-friendly commands
 - Headless: tag_mode (AND/OR) accepted from JSON and environment and exported in interactive run-config JSON
+ - Owned lists are enriched at upload-time and persisted in an internal store; header rows skipped and duplicates deduped; per-request parsing removed
+ - Builder Review (Step 4): "Use only owned cards" toggle moved here; Step 5 is status-only with "Edit in Review" for changes
+ - Minor UI/CSS polish and consolidation across builder/owned pages
+ - Deck summary reporting now includes colorless 'C' in totals and cards; UI adds a Show C toggle for Sources
+ - List view highlight polished to wrap only the card name (no overrun of the row)
+ - Total sources calculation updated to include 'C' properly
 
 ### Fixed
 - Docker Hub workflow no longer publishes a `major.minor` tag (e.g., `1.1`); only full semver (e.g., `1.2.3`) and `latest`
+ - Owned page internal server error resolved via hardened template context and centralized owned context builder
+ - Web container crash resolved by removing invalid union type annotation in favicon route; route now returns a single Response type
+ - Source highlighting consistency: charts now correctly cross-highlight corresponding cards in both list and thumbnail views
+ - Basics handling: ensured basic lands and Wastes are recognized as sources; added fallback oracle text for basics in CSV export
+ - Fetch lands are no longer miscounted as mana sources
