Milestone M1: 1.13c Nova (Skill 48) Implementation & 7-Dimensional Verification Report

Commit: 35b9267 (Merged into main)
Test Suite: tests/skills/sor/skill-048-nova.test.ts (17 of 17 tests passed)

7-Dimensional Verification Results:

  • D1 (1.13c Data Table Parsing & Canonical Missile Definition): Verified Skills.txt row 48 (Nova: Id: 48, srvdofunc: 22, mana: 15, lvlmana: 1, castoverlay: light_cast_1, srvmissilea: nova) and Missiles.txt (nova: ID 90, vel: 24, range: 13, speed: 600 px/s, distance: 312 px, animLen: 13, nextHit: 1, nextDelay: 4, trans: 1, celFile: electricnova).
  • D2 (Visual Assets & Metadata Integrity): Verified atlas sprite sheets public/missiles/electricnova.png/.json (451KB) and public/overlays/light_cast_1.png/.json (48KB) with additive blend mode (BlendMode.ADD).
  • D3 (Kinematics & 64-Bolt Circular Ring Dispersion): Verified 64 bolts emitted in uniform 2*pi radial distribution with 2:1 isometric ground foreshortening (y = sin(theta) * 0.5, x = cos(theta)), initial velocity 600 px/s, max distance 312 px.
  • D4 (NextDelay = 4 Single-Hit Lockout Protection): Verified multiple overlapping bolts on a single target register exactly 1 hit due to 4-frame target immunity window (nextDelayByTarget tracking).
  • D5 (Obstacle & Terrain Collision Clipping): Verified bolts hitting solid tiles (isTerrainBlocked returning true) immediately expire (m.expired = true), while open-air bolts continue to their maximum range.
  • D6 (1.13c 5-Band Damage Scaling & Synergy Verification): Verified exact 1.13c 5-band piecewise formula:
    • slvl 1: 1–20 (avg 10.5)
    • slvl 10: 57–94 (avg 75.5)
    • slvl 20: 131–188 (avg 159.5)
    • slvl 30: 221–298 (avg 259.5)
    • Synergies: 0% synergy from other skills per 1.13c ground truth.
  • D7 (WorldArena & Runtime Cast Integration): Verified integration with WorldArena, MissileEngine.spawnNovaRing, castSkill, mana deduction 15 + (slvl - 1), 0 cooldown, and cast overlay light_cast_1.
