Description
1.0.0 readiness: Hydrology routing
Area: Hydrology Functions: flow_direction, flow_accumulation, flow_length, flow_path, watershed, hand, stream_order, stream_link (d8/dinf/mfd)
Source: xrspatial/hydro/
Scope
- Public surface frozen against the README feature matrix
- Dark-corner decisions resolved (see #2930)
Sweep clearance, no CRITICAL or HIGH (accuracy and security first)
- Accuracy
/deep-sweep xrspatial/hydro - Security
- Performance
- API consistency
Last swept: none yet
Examples
- Notebook example
- (optional) standalone script
Linked bug issues
- #2796 (High) flow_path_dinf hangs forever on cyclic D-inf flow directions
- #2885 (triage) Extend lazy MFD dask assembly to stream/hand modules and study the convergence phase

Research direction
Start in xrspatial/hydro/ and review the listed routing functions against the README feature matrix. Read the dark-corner decisions in #2930, then inspect the deep-sweep scope and linked issues #2796 and #2885. Done means the public surface is frozen, sweep findings have no CRITICAL or HIGH issues, and the notebook example is complete.
