+Navigation particles appear only in the base's world and when the player is more than 25 blocks beyond the current base border.
+
+After 250 Survival-mode block placements anywhere by default, the spawnable overlay can mark nearby dark hostile-mob spawning surfaces inside the player's base with owner-only red particles. The threshold is configurable.
+
 `/base` has a stationary warm-up. Looking around is allowed, while movement between blocks, damage, teleportation, world changes, death, logout, and conflicting teleport commands cancel it without consuming the cooldown.

+## 2026-08-10 — Base border visualization
+
+- Added persisted, owner-only base border particles controlled by `/basesettings border enable|disable` with contextual autocomplete.
+- Rendered a bounded nearby arc at the player's current height using the current base radius while respecting world and vertical bounds.
+- Added border preference reporting to player and administrative status output and safe defaults for existing state files.
+- Verified the feature with `./gradlew clean check jar`.
+
+## 2026-08-10 — Spawnable block overlay
+
+- Added persistent progression for Survival-mode block placements anywhere, with existing in-base placement counts used as a safe migration minimum.
+- Added `/basesettings spawnable enable|disable` after a configurable 250-placement unlock and reported its progress and preference in player and admin status output.
+- Added admin controls for total placement progress, the unlock threshold, and each unlocked player's overlay preference.
+- Added owner-only red particles for nearby dark spawning surfaces inside base bounds, using bounded incremental scanning and rendering budgets.
+- Verified the feature with `./gradlew clean check jar`.
+
+## 2026-08-10 — Navigation visibility buffer
+
+- Limited enabled base navigation particles to the base's world and positions more than 25 horizontal blocks beyond the current base border.
+- Used the live size-tier radius so expansion and relocation immediately update the visibility threshold.
+- Added exact-boundary and controller integration coverage.
+- Verified the change with `./gradlew clean check jar`.

+# US-014: Highlight spawnable blocks
+
+As a **player with an established base**, I want to highlight nearby blocks where hostile mobs can spawn so that I can find lighting gaps in my base.
+
+## Acceptance criteria
+
+- [x] Every block placed in Survival mode anywhere contributes to a persistent total-placement counter.
+- [x] The overlay unlocks permanently at a configurable 250 total placements by default.
+- [x] Existing players begin with at least their persisted in-base placement count because those placements are known to qualify.
+- [x] `/basesettings spawnable enable` enables the unlocked overlay idempotently, and `/basesettings spawnable disable` disables it idempotently.
+- [x] `spawnable`, `enable`, and `disable` are offered through contextual autocomplete.
+- [x] Enabling requires both the placement unlock and an established base; the persisted preference defaults to disabled.
+- [x] `/basesettings status` and `/baseadmin status` display placement progress, unlock state, and preference.
+- [x] Administrators can change a player's total-placement counter through `/baseadmin setprogress`.
+- [x] Administrators can persistently change the required placement threshold through `/baseadmin config spawnable-overlay-unlock-placements`.
+- [x] Administrators can enable or disable an unlocked player's overlay through `/baseadmin setsetting <player> spawnable <enable|disable>`.
+- [x] Owner-only red particles mark nearby candidate hostile-mob spawning surfaces inside the current base bounds.
+- [x] Candidate surfaces have block light zero, a solid spawning surface, and two passable blocks above them.
+- [x] Scanning is bounded to 16 horizontal blocks, eight vertical blocks, and a fixed per-update work and particle budget.
+- [x] A complete administrative reset clears total-placement progress and disables the overlay.
