Effective Instruments

[1.6.0] - 2026-07-01

Added

• Datapack-driven aura data. Aura presets, instrument→aura mappings, and durability metadata now load from datapacks (data/<namespace>/effectiveinstruments/aura/{presets,instrument_map,mobile_instrument_map,durability}/) via a reload listener that re-runs on server start and every /reload. The mod ships its defaults as a generated datapack; modpacks can add or override any of it. Legacy config/effective_instruments/ files still layer on top as overrides (gated by allowConfigOverrides).
• Client preset sync (SyncAuraDataS2CPacket). Remote clients receive the server's preset registry + mappings so the selector overlay works on dedicated/LAN servers. Sent on login and after every server reload (via OnDatapackSyncEvent). Wire protocol bumped to 5 — pre-1.6.0 clients cannot populate a datapack-driven registry, so the handshake mismatch is intentional.
• IAuraPerformer seam (PlayerPerformer) — groundwork for non-player performers; player behavior is unchanged.

Fixed

• Malformed datapack JSON (bad field type, invalid effect id) is now isolated per entry and can no longer abort world load or leave the aura registry half-cleared; the registry is swapped in transactionally.
• The reload listener no longer reads SERVER config before it loads (regression of the 1.4.9 split); pre-config reads route through safe accessors.
• Effect cleanup no longer strips beacon / other-mod effects that merely share an aura's amplifier and ambient flag — it now matches on the recorded expiry.
• Vanilla /reload re-syncs presets to clients (previously only login and the EI commands did).
• Mobile autoplay auras now activate in every dimension (discovery scan was overworld-only) and are cleared from the active set on logout.
• Server authority: stationary aura selection requires a held tracked instrument, and the mobile screen-open path requires the claimed instrument to actually be held — closing two client-trusted-state holes.
• Spectators, snow golems, ambient creatures, and neutral mobs are no longer hit by offensive auras under the default config.
• Per-note aura application is throttled, and mobile aura radius is capped to the mobile tier's bound.
• Packets now declare their network direction; a .gitattributes normalizes line endings (gradlew stays LF).
