 - Added `/homenavigation`, `/homeflight`, and `/homevisitors` aliases with the same autocomplete as their canonical commands.
 - Generalized toggle preference resolution for navigation, flight, and visitor access.

+## 2026-08-10 — Unified base settings command
+
+- Replaced the separate progress, navigation, flight, and visitor commands with `/basesettings` and its `/homesettings` alias.
+- Added nested autocomplete for status, Base IV upgrades, visitor access, navigation, flight, and progress boss-bar settings.
+- Moved the Base IV purchase from `/base upgrade` to `/basesettings upgrade`, leaving `/base` and `/home` dedicated to personal teleportation.
+- Preserved the full progression report as the default `/basesettings` response and as `/basesettings status`.
+- Verified the breaking command restructure with `./gradlew clean check jar`.
+
+## 2026-08-10 — Administrative command autocomplete and reset safety
+
+- Added `/homeadmin` as an alias for `/baseadmin` and replaced the administrative `progress` subcommand with `status`.
+- Added permission-aware, context-sensitive autocomplete for subcommands, online and known offline players, paths, levels, counters, cooldown types, reset confirmation, and numeric configuration keys.
+- Removed the unsafe unconfirmed base reset path; complete resets now require `reset <player> all confirm`.
+- Tightened argument validation and replaced implementation-specific enum errors with player-facing usage guidance.
+- Verified the administrative revision with `./gradlew clean check jar`.
