Build 2872 — 2026-09-23

Branch: update/paper-26.0.x

Performance + stability pass based on Spark profiles from a busy production server. No cargo/android behavior changes.

Fixed

• Sound crash: Legacy sounds.yml Bukkit enum names are now migrated to valid namespaced sound keys.
• Deferred inventories: Entries are now removed when blocks are destroyed and moved correctly when blocks move.
• Auto-reporter noise: Skips addon linkage errors and plugin lifecycle failures.
• Daily reporter limit: Maximum 2 automatic reports / rolling 24h per server.

Performance

• BlockStorage: getRawStorage() now uses a lazy cached snapshot instead of rebuilding the entire world map every call.
• Cargo: Avoids unnecessary tile-entity/container state copies on hot paths.
• Cargo filters: Removes debug varargs allocations when debug logging is disabled.
• Cargo distribution: Reuses ItemStackWrapper until the stack amount changes, avoiding unnecessary ItemMeta clones.

Investigated

• Cargo filter routing and Woodcutter/Programmable Android ticking are legitimate workload; no safe optimization found without changing behavior.
• Reverted unsafe distributeItem wrapper hoist because it could freeze stack amounts and change machine slot selection.

Result: Lower allocations and server-thread overhead while preserving existing cargo, android, and machine behavior.
