CANON SUBORDINATION — this document is PROPOSAL-TIER: it serves canon and never outranks it.

PROPOSAL-TIER. This kit serves canon and never outranks it. It writes no registry row.
The law it obeys: docs/proposals/combat/KIT_SCALING_TABLE.md. The intelligence scale:
docs/proposals/combat/INTELLIGENCE_TIERS.md. The body it fights with is the bestiarylane's: docs/proposals/bestiary/BESTIARY_ELEVATION_DOCTRINE.md and its sheets. This file
describes the FIGHT; it never restates the BODY. Authors no magnitude -- no damage, no
health, no timing, no coefficient. Those are Phase-5M's behind the tuning firewall.

Silhouette read. The crossing, and something in it that the current is going around.
Opener (MHM-G10, the cheap lesson first). THE STILL LENGTH -- a body lying in fast water and not moving with it. Free, and it tells the player exactly where the lane is before it costs anything.
| phase | name | what it PUSHES (nothing pops) |
|---|---|---|
| 1 | the guarded traverse | the rapids and the coil together. Timing and lane-reading. |
| 2 | the calm | BE_0011_S3's evolve-not-swap clause: it TIGHTENS THE SAFE LANE. Same water, same animal, less room -- and then it withdraws. |
| # | ability | phase | body origin | tell shape | counter | note |
|---|---|---|---|---|---|---|
| 1 | The Still Length | 1 | the whole body, anchored across the ford | a length in fast water that is not moving with it | any | |
| 2 | The Constriction Lane | 1 | the trunk laid across the crossing | the coil tightens one turn and the head drops level | dodge_only | The row's counter -- 'step the constriction lane on the tell'. The player already knows this shape from Chapter 2, and the chapter is counting on it. |
| 3 | The Strike | 1 | the neck, from the anchored coil | the head levels and the throat inflates once | parry_only | |
| 4 | The Slack Window | 1 | the rapids' own period | the standing wave at the ford flattens | trigger_interrupt | The row's second counter -- 'time the crossing to the rapids' slack window'. composure_nodes = environmental=rapids_slack_time. |
| 5 | The Drag | 1 | the current itself, on a body that has stopped moving | your own footing shifts downstream while you are standing still | cover | EG_0166 and EG_0167 both carry exposure_hazard = drag. |
| 6 | The Anchor Shift | 1 | the tail walking to a new hold on the bank | the tail leaves its hold before the head moves | any | Read the tail, not the head. The same lesson as KIT_MF_CONSTRICTOR, in a current. |
| 7 | The Submerged Approach | 1 | the body, moving under the surface | the water's texture changes upstream of where it was | dodge_only | |
| 8 | The Tightened Lane | 2 | the same coil, closer to the only crossing point | the safe gap is narrower than the ford is wide | dodge_only | MHM-G10's variant law: ability 2's root at a width where stepping the lane stops working and timing has to carry it. |
| 9 | The Held Strike | 2 | the neck, from a coil that does not reset | the throat inflates and the head is already level | parry_only | |
| 10 | The Bank Pin | 2 | the animal between the player and the staging point | it anchors on the bank you came from | cover | |
| 11 | The Read Lane | 2 | the crossing, once its geometry is understood | the coil's shape stops changing between cycles | neutralize | win_condition = PERCEIVE;BYPASS;REDUCE, win_shape = passage. PERCEIVE and BYPASS are two of the three, and this ability is both. |
| 12 | The Withdrawal | 2 | the animal releasing its anchor and going downstream | the still length starts moving with the water | any | has_nonkill_path = TRUE. It leaves. The crossing was never the animal's to lose. |
CLASS PURITY (tooth T5). Every move above is physical. No element family, no vril
mechanism, no non-ordinary affordance appears in this kit, because this being's own canon
row carries no hollow row, no lore home and nothing that elevates it. It is dangerous the
way the real animal or the real person is dangerous, engineered up until it reads at the
shipped combat camera. TIMID here would mean BORING-PHYSICAL, never insufficiently magical.
| part | moveset subtraction on break | legibility gain | material the economy wants |
|---|---|---|---|
| the bank anchor | The Constriction Lane (2), The Anchor Shift (6) and The Bank Pin (10) lose their fixed point | the body starts moving with the current, which is the same readout as the withdrawal and arrives earlier | patterned hide -- and taking it costs the Thread-2 serpent-reverence track, as it does everywhere else in the arc |
| the ford's standing wave | The Slack Window (4) becomes permanent once the upstream obstruction is shifted -- the crossing calms | the water's surface stops pulsing | nothing harvested; the river is not a resource |
EG_0167 Constriction Lane and the Rapids Slack Window -- BOTH: enemy_usable = TRUE, CONSTRICTION, D6_CONDUCT, exposure_hazard = drag. The row's own name is this encounter.EG_0166 Ituri Rapids Reach and the Shifting Ford -- BOTH: enemy_usable = TRUE, TRAVERSAL_SURFACE, D6_CONDUCT, drag. The crossing.EG_0168 Bank Staging Point and Saturated Mud Margin -- BOTH: enemy_usable = TRUE, material:saturated_earth. Where ability 10 pins you.EG_0154 Closed Ituri Canopy Three-Strata Volume -- CARE-BOUND, GEOMETRY ONLY: hard_blocked, enemy_usable = FALSE, attack_verbs = none. The forest over the crossing is never cut or burned.| channel | what the player sees or hears |
|---|---|
| posture | the coil comes off the bottom and holds itself in the current, which costs it and shows |
| breath | the flank pumping visible at the waterline goes shallow |
| vocal | none -- and the river's own noise, which has been constant, is the thing that changes when the animal moves under it |
| opener | The Still Length is retired; The Constriction Lane becomes the opener |
IT ENTERS by being in the water already. IT RELOCATES by anchor, slowly. IT LEAVES downstream. WHAT IT DOES TO THE ARENA: it makes one ford into a timing problem, and the river was already doing half the work.
care_tier = standard, target_type = fauna, MUNDANE, has_nonkill_path = TRUE, win_shape = passage. An animal in a river. The Thread-2 serpent-reverence cost on killing it is the arc's standing one and this kit prices it the same way BE_0002_S1 does. The Ituri forest rows are hard_blocked and the crossing is staged in the water so that nothing of the Efe and Mbuti communities' ground is fought over.
This kit is authored ONCE, at Fading. The five modulators of KIT_SCALING_TABLE section 4
express it across the ladder: active_ability_set grows upward through reserved follow-ups
on roots the player already learned, window_class tightens, answer_tree_depth prunes
toward the single true answer, hazard_concurrency rises with the arena rows above, and
phase_overlap interleaves the phase cycles. No second kit exists and no number here changes
with the tier.
