The first foe with an ATTACH state machine, and the first that gives boost a defensive job.
Giardia chases like a seeker, CLAMPS its ventral suction disc onto your hull, and drains coat
while it rides — until a boost's i-frames throw it (or it lets go after attachMax, then can't
re-grab for reattachCd). The counterplay is timing a boost, not out-running it.
- enemies.js: `latcher` archetype — a two-state (chase / attached) branch. Attached, it rides
player.pos + a spin offset and drains `drain`/tick; ps.iframeT > 0 (boost) detaches and flings
it clear. Amber tetrahedron (the trophozoite), so a clinging one reads on the hull.
- levels/enemies.js: ARCHETYPES += latcher; catalogue `giardia_latch` (biome small_intestine).
- L2: one Giardia previewed on the open thoracic run (s1940) — it belongs to L4's villi maze,
but the grab works in a flow tube, so it teaches the boost-dodge verb now.
Verified: it chased + clamped, drained coat 100->84 while attached, and a simulated boost
(iframeT) shook it off.
