The two things I deferred out loud, built — and the second one turned out to be the primitive
the first was waiting on.
THE CHURN (the force primitive). Everything in hazards.js pushed the player RADIALLY; nothing
applied a tangential one, which is why both L3's cyclones and the Guardian's arena churn got
deferred. `churn` is now a hazard kind: a tangential impulse that REVERSES on a period, so it
cannot be leaned into, only re-read. Measured: 4.32 u/s of push, direction flipping.
- L3 s1100: cyclones spanning the sea, deliberately overlapping the first tide — the room
starts spinning you at the exact moment the safe air starts shrinking.
- The Pyloric Guardian carries its own (`def.churn` + per-phase `churnMul`), so C's spec is
finally honoured in full: "pushes you at the walls", x1.5 in P2, harder in P3. Measured
2.7 u/s on the player mid-fight. The boss.js header that said this was missing is corrected.
THE TAPEWORM (LANE_C_NOTES §2), the campaign's third pressure: a DISTANCE race. One new idea in
the schedule — `flee` — advances the boss's own s and drags its ring along at fixed offsets, so
6 proglottids string out 70 units down the tube ahead of you instead of sitting in a
cross-section. Fall 110 units behind and it is gone. Verified both ways: fall behind ->
"escaped" after 16.8s having seen only P1; keep up -> all three phases -> win. C's line was "a
chase you can lose without dying", and that is now literally the outcome table.
Placed at L4 s5460, immediately before the biofilm cash-out, so the chase and the reward land
together. L4's "no_miniboss_yet" note is replaced rather than left lying.
PRE-PLAYTEST SWEEP: 6/6 levels valid, all load with ZERO console errors, every level carries
exactly 3 biopsy samples, five bosses across the campaign (mast_cell / pyloric_guardian /
tapeworm / the_blockage / appendix_sovereign), 16,820 units of authored canal, and the chain
resolves L1 -> L2 -> L3 -> L4 -> L5 -> end with LS_appendix rejoining at L5.
Everything in the GDD's roster now exists except the numbers being right, and that is the part
only humans can tell us.

The three acts are anatomical, not invented: Giardia colonises the duodenum and jejunum, and Peyer's patches (the antibody turrets) concentrate in the ileum.
