A height or biome query from the tick thread no longer blocks on a cold
hydrology plan: it answers from the natural streams and asks the
planning pool for the tiles meanwhile. A new world prefetches the tiles
around spawn when the generator is injected, and the hydrology pool gets
full parallelism instead of a third. Also stops the shared corner-bounds
cache from pinning a non-finite sample and fences its two stamp reads.
Brings master's Sentry removal, bound platform classification, Vision
entity toggle, release version and generation context binding onto the
rivers rework while keeping the hydrology system master had removed.
Hydrology files master deleted are restored from the branch, master's
non-hydrology edits are kept, and the modded adapter builds drop the
Sentry dependency with master.
Also removes the ridge_tunnel find selector: no course publishes ridge
bores any more, so it could never return a result.
- channel.springWidthRatio / springLength open every surface river in a pool that shrinks where the ground falls away
- Banks settings keep structural invariants only; authoring bounds stay in the validator
- Feature searches walk tiles outward and stop early; find and goto report progress per ring
- 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
- Remove automatic error reporting and server-identifying attachments.
- Remove Sentry dependencies, release tooling, settings, and test commands.
- Keep failures operator-visible through local stack traces and logging.
