- Ocean integrity fires on land columns near a mouth; shallow incision and bank continuity are gates
- Probe-local centerline and turn helpers replaced by production geometry
- v1 checks for ridge bores, endpoint ramps, terminal caps, transition recovery and pool lengths removed
- Head ring now covers every cell that can sit beside water
- Blend widths are smoothed along the course; the bed is a broad bowl
- Diagonal shore cells keep the lip; cross-section rows belong to their own station
- Transect probe prints coordinates and numeric section tables
- riverTransectProbe renders each surface course as a plan and five cross-sections
- Summary gates ocean writes and spilling channel cells
- Grading columns now report the bank biome
- Replace hydraulics, ridge tunnel, branching and inset ranges with channel, banks, flow and mouth configs
- Add routing cost weights, underground mouth leveling, bank biomes and bank multiplier
- Map the new schema into planner settings and derive refinement spacing
- Replace the river package with the hydrology planner, footprint compiler, cave containment and runtime
- Add the hydrology pack schema, validator, probes and tests
- Wire hydrology into IrisComplex, actuators, mantle, Vision and commands
