Adds the server-authoritative mechanics for three new enemy archetypes on top of
the Grunt/Charger base, plus the weighted wave-composition that introduces them:
- Spitter: a ranged Husk variant (SpitterState) that holds a preferred range-band
(advance/retreat/hold via EnemyAIMath.BandVelocity) and fires a telegraphed,
dodgeable EnemyProjectile. New server EnemyProjectileMoveSystem (integrate +
store LastStep) + EnemyProjectileDamageSystem (region-filtered swept hit-test
rebuilt from LastStep — DR-018 anti-tunnelling; players use HitRadius, structures
a const radius; at-most-once destroy). Concurrent-spit soft cap, soft-fail retry.
- Swarmer: marker tag + deterministic cluster spawn (1 slot = 1 pack;
EnemyAIMath.ClusterOffset), MaxAlive counts ENTITIES so a pack defers if it
won't fit.
- 4-type weighted mix: MixBands -> ZoneEnemyMath.WaveSlots/KindForSlot/
PackSizeForSlot drives both the expedition director and (fork-4a) the base siege,
with a mandatory MaxAlive cap. Legacy WaveSize/IsChargerSlot kept + parity-tested.
- Discriminator stays component-presence (no enum in Bursted systems): query-
partition guards keep each enemy moved by exactly one EnemyAISystem pass
(sole-Position-writer). EnemyTelegraph.IsCharger -> Kind byte for the client cue.
New authoring (Spitter/Swarmer/EnemyProjectile) + expanded director authorings with
tunable mix/cluster defaults. 13 new EditMode tests (mix composition + legacy parity,
band/cluster math, projectile move + cross-region + swept anti-tunnelling regressions);
full suite green before commit.
Dormant until the prefab/subscene wiring lands (next): the new systems guard on
TryGetSingleton/RequireForUpdate, so with no prefabs wired the new types stay inert.

Reactivate the dormant Expedition region as a procedural combat venue.
v1 loop: walk the gate -> fight an epoch-seeded enemy wave in the
expedition -> clear -> return -> flat Ore reward (once per epoch) ->
escalated retaliation base siege.
- New sim types: ZoneEnemyTag, ZoneEnemyDirector (+ ZoneEnemyPrefab
buffer), ZoneEnemyState, ZoneEnemyMath (grunt->charger composition
by epoch). ZoneEnemyDirectorSystem (server, Burst): drip-spawns the
wave at a deterministic ring under a MaxAlive cap while a player is
out and the base is Calm; marks ClearedThisEpoch on a real clear.
[UpdateAfter(ExpeditionFieldSystem)] only (avoids a sort cycle).
- BLOCKER 1: EnemyAISystem region-filters target selection (player +
structure snapshots gain parallel region lists; no base structures /
no Core fallback for expedition husks).
- BLOCKER 3: WaveSystem, ThreatDirectorSystem timeout cull, and
CyclePhaseSystem DefendCleared + Core-breach cull all count/cull
RegionTag{Base} husks only (the breach cull was caught region-blind
by the post-impl review: a base breach wiped the live expedition
wave and spuriously paid the reward).
- BLOCKER 4: reward de-duped via CycleRuntime.LastRewardedEpoch +
ClearedThisEpoch; ExpeditionGateSystem deposits RewardOre once/epoch.
- ExpeditionFieldSystem teardown also culls zone enemies + region-
guards the clutter loop. Subscene wired with the director + roster.
368/368 EditMode green + clean netcode Play smoke. Docs: DR-040 ->
built, session log, CLAUDE.md cross-region tag-reaudit rule.
