Weekly Update March 23, 2026

Highlights

• Georeference workflow expanded with persistent metadata and canvas point picking

• EPS pipeline improved with dense buffers, caching, and adaptive detail for smoother performance

• Better recovery from stale chunk errors and SewerCalc build fix

• Unified Next.js 16.1.1 patch rollout and groundwork for future automation

What's New (By Category)

UI/UX

• Expanded georeference flow now includes persistent spatial metadata, coordinate reference controls, fit preview with residuals, and canvas-based point picking.
• Added dedicated panel exposing EBCQ remediation ranking with progress state and JSON export.
• Improved menu overflow behavior, sidebar accessibility labels, and messaging when local auth is disabled.

Solver and Engine

• New ranking logic combines EBCQ, unsupplied demand, and pressure deficit into a weighted remediation score with exportable results.
• No major changes to core hydraulic methods; focus was on analysis and visualization infrastructure.

Performance

• EPS pipeline now emits stable visual ordering and dense typed arrays for visualization.
• Canvas overlay selector reads dense data first and caches per-step overlay materialization to improve smoothness.
• Link geometry caching and adaptive visual detail based on zoom and network size.

Bug Fixes

• Improved client recovery with one-shot reload on stale chunk 404 errors.
• Fixed SewerCalc server build to avoid dependency on ignored SWMM dist artifacts.

Infra and Dev Experience

• Next.js 16.1.1 patch applied across all monorepo apps; watdis-next rebuilt successfully.
• Local OpenClaw scaffolding added to support future weekly automation.
• Prepared rehydration docs for transferring working setup to another workstation without version-sensitive runtime state.

Coming Next

• Improve georeference fit accuracy and extend beyond local tangent-plane approximation.
• Profile and tune adaptive detail thresholds for EPS visualization on real large networks.
• Refine cache invalidation to support in-place data mutations rather than full replacements.
• Advance comprehensive static asset cache invalidation for deployments.
• Enhance unsupplied demand estimation for pure EPANET runs.
