Add pothole detection as new menu type with separate engine and research plan

UX: add choose detection type screen and redirect URLs

Add landslide detection menu, separate engine, and Uttarakhand integration plan

AI/Hybrid overhaul: bidirectional AI fusion, stronger hybrid sensitivity, keep large unclassified regions

AI rework: percentile+blur threshold + less aggressive cleanup; Hybrid lower threshold

Fix: fallback to Image Difference when AI/Hybrid mask is too sparse

Detection fix: ECC registration fallback + less aggressive large-region rejection

Detection tuning controls + threshold diagnostics in API response

Email API: attach populated ChangeDetection.html report (base64)

Email API: send required FileName and AttachmentBase64 placeholders

Use manager email API for notifications (multipart/form-data); SMTP fallback

Revert Resend; use SMTP only, custom email API to be integrated later

Use Resend HTTPS API for email (HF Spaces); SMTP fallback for local

Force fresh HF deploy with version 2.2.0 and new asset cache keys

Make HF startup path simpler and add explicit startup logging

Rework email notifications with explicit send actions.

Switch email from SMTP_SSL:465 to STARTTLS:587, restore sender, show failure feedback

Bump version to 2.1.0, add version+IST time to /health for deploy verification

Convert timestamps to IST server-side so display is correct regardless of browser cache

Fix history timestamps: append UTC offset so browser converts to local time

Full codebase audit: fix critical perf bug, security, error handling, dead code

Save full-res before image so the before/after slider works from history View

Improve detection accuracy: border exclusion, threshold floors, fill-ratio filter, NMS, tighter bboxes

HF fix: uvicorn-only CMD, defensive mkdir, remove unused numpy, overlay mkdir on save, README troubleshooting

Fix HF restart loop: /health endpoint, resilient migration, lazy-load detection_engine

History table view, zoom, severity markers, row hover highlight, before/after thumbnails

Add email notification feature with Notify checkbox, SMTP backend, and HTML template

Add Delhi zone/village dropdowns, location tracking, and project documentation

Add vegetation and structural sub-classification for detected changes

Add 3D building analysis: shadow-based height/stories estimation and construction stage classification

Code review fixes: SSIM stability, symmetric CLAHE, confidence scoring, KMeans perf, auth hardening, remove debug endpoint

Add forgot password flow and password visibility toggle

Add detailed error logging to register/login endpoints

Fix: writable data dir for HF Spaces, pin bcrypt 4.0.1

Fix: add checkfirst=True for table creation, use 1 worker
