- 8 new enemy types (frames 50–57) split 4/4: combo seekers fire flank-angle homing missiles with capped turn-rate; elementals throw darts that bloom into growing, damage-ticking electrified zones
- Balance follows the faction rule (2× damage, 3.5× armor vs pirate raider), documented in combat.json comments
- New `flank_barrage` and `shock_dart` abilities in EnemyAbilities.js with shared `stepShock` frame step wired into CombatSystem.update
- Generalized `_combatBootMode` to accept any id from `factionIds()` so new factions need no code change
- Painted frames 50–57 in ships-enemy.png/.psd; added capital-mindweave-surface-01 reference art
- Tests: dev/zenith.test.mjs (Node), dev/zenith-arena-browser.mjs (Playwright), updated combat.test.mjs roster and sheet-art checks, extended cdp-faction-arena.mjs with zenith tab
- New EncounterDirector (js/combat/Encounters.js): pure, data-driven clock that rolls pirate / neutral / mixed encounters in neutral non-home systems on a ~45–90s interval at 50–60% chance, one at a time with a 30–60s cooldown, never during a live wave run or on a downed player.
- Neutral ally ships (js/combat/NeutralShip.js) on spritesheet frames 20–27: escort the player for a per-ship 10–15s window, engage the nearest pirate in mixed fights, then break off and fly off-screen; player-safe by construction (never targeted or damaged by ally bolts/seekers).
- Pirate targeting generalized so hostiles can draw aggro onto escorts when the player is out of range; escort and pirate bolts/missiles collide with each other but not the player.
- Group size scales with combat level (1–2 low → 4–5 high, bands in data/combat.json); encounter hostiles are one-shots so the fight ends when the sky clears.
- New 'volley' weapon pattern (wide staggered-speed fan) and owner-tagged bolts/missiles for ally vs enemy routing in Weapons.js.
- Neutral roster config + encounters section added to data/combat.json; EnemyTypes gains neutralTypeConfig/Ids/SheetList.
- Tests: dev/encounters.test.mjs (cadence, gate, weights, size bands), dev/neutral.test.mjs (roster, escort AI, targeting, no friendly fire), plus combat/xp test updates; CDP probes and encounter-hud-check for in-browser HUD verification.
- New `combat.html` + `/combat` dev-server route + `index.html?combat`
boot a fixed arena where the player ship fights a pack of enemy craft;
all tuning lives in `data/combat.json` (thrust, hulls, shields, lance,
rams, respawns).
- Add `js/combat/` modules: CombatScene, EnemyShip (standoff-ring AI +
lance), Bullet, Fx, StarDrift, and pure rules in Combat.js (armor
damage, orbit step) exercised by the new `dev/combat.test.mjs`.
- Extract shared `awaitFonts` into `js/utils/Fonts.js` so both the game
and sandbox boots use one copy.
- Preload the enemy spritesheet in GameScene so the texture is ready when
combat ships in; add `ships-enemy.png` (+ `.psd`) art.
- Expose `window.__COMBAT__` (reset, spawnEnemy, player, kills) for
devtools tuning; R resets the range, P freezes it.
