Ars 'n Spells

[2.6.0] - 2026-06-14

Apotheosis / Apothic Curios mana bridge

Affixed and socketed curios (rings, amulets, belts) now contribute their mana stats to the unified Ars ↔ Iron's pool. The equipment scanner already read attribute modifiers off armor and weapons — so Apotheosis affixes there always worked — but the curio path read only IManaEquipment and Ars enchantments, so an affixed/socketed ring's max-mana or mana-regen never reached the cross-mod bridge. A Mana Battery Ring took effect in its own system's pool but was invisible to the other.

• Curios attribute modifiers are now read and mirrored. EquipmentIntegration.java enumerates worn curios via the Curios API (CuriosApi.getCuriosInventory(...).findCurios(...)) and reads each slot's aggregated attribute modifiers (CuriosApi.getAttributeModifiers(slotContext, uuid, stack)), summing Ars max_mana/mana_regen and Iron's max_mana/mana_regen through the same sumModifiers helper and ADDITION-only rule the armor path uses. This routes Apotheosis (with Apothic Curios) affixes & sockets — and any other curio mana gear such as Magical Jewelry or Jewelcraft — through the existing bridge. No double-counting: the curio's own pool already gets the modifier natively; the bridge only mirrors it to the other system, exactly as armor does.
• No hard Apotheosis dependency. The read is generic (any mod's curio mana attributes), gated behind the new read_curio_attribute_modifiers config (default on) and wrapped so any API surprise degrades to "no bonus" rather than a crash.
• Spell power needed no change — it is read from the player's total attribute, so affix spell power on armor/weapons/curios already counted. Apothic Attributes' own attributes (crit, armor pierce, fire/cold damage) are combat-only and out of scope for the mana/spell bridge.
• Build: build.gradle adds a compileOnly Curios API dependency (5.9.1+1.20.1, the version Ars Nouveau bundles at runtime). Curios is always present at runtime via Ars, so this only puts the slot-aware API on the compile classpath.

Ring / aura-HUD correctness and hardening

• Aura-bar peak tracker is now lock-free. ClientAuraPeakTracker.java stores the personal peak in an AtomicInteger with a monotonic getAndUpdate ratchet, so the render-thread read in the HUD mixin composes cleanly with client-tick writes (and stays correct if a sync writer is ever added).
• Covenant version-drift probe. ArsNSpellsClient.java logs at startup whether Covenant of the Seven is at the version the aura-bar HUD mixin (MixinResourceBarOverlay) was bytecode-verified against (2.2.6). The mixin uses require = 0, so a mismatch can't crash the client; this makes the silent fallback diagnosable instead.
• Virtue aura system honors its toggle. VirtueRingHandler.java now short-circuits its handlers when ENABLE_VIRTUE_AURA_SYSTEM is off.
• Dead alternate-resource stubs removed. CastingAuthority.java dropped the never-implemented detectAlternateResourceCost/validateAlternateResource path (it always returned null/true); Cursed/Virtue ring costs are owned by their dedicated event handlers.

Performance (render + tick hot paths)

• OPT-008: MixinArsPotionEffects.java only churns the mana attribute modifiers when the value actually changed, instead of a remove/add every server tick (which forced an attribute recompute).
• OPT-009: ManaBarController.java matches mana overlays on the ResourceLocation namespace/path directly (allocation-free equals) instead of toString() + substring scan every overlay every frame. The matchers are extracted as pure, package-private, unit-testable methods.
• OPT-010 / MED-019: OverlayDiagnostics.java registers its per-frame render subscriber on the Forge bus only while diagnostics are enabled (zero dispatch cost when off, the default), and uses a TreeSet for already-sorted iteration.
• IronsLP debug trace gated. IronsLPHandler.java builds its per-cast entry-trace strings only when LOGGER.isDebugEnabled().

Tests

• New unit coverage for the above: ClientAuraPeakTrackerTest (monotonic ratchet), ManaBarControllerOverlayMatchTest (overlay matchers), and VirtueRingAuraToggleTest (toggle gating).
