+Title: Hide edit controls for non-owners in frontend
+
+## Reasons for Scrapping
+
+This crash bean is a false positive. The original task (nuzlocke-tracker-i2va) was already completed and merged to `develop` before this crash bean was created:
+- Commit `3bd24fc`: fix: hide edit controls for non-owners in frontend
+- Commit `118dbca`: chore: mark bean nuzlocke-tracker-i2va as completed
+
+No additional work required.

+title: Support ES256 (ECC P-256) JWT keys in backend auth
+status: completed
+type: bug
+priority: normal

+updated_at: 2026-03-22T10:59:46Z
+---
+
+Backend JWKS verification only accepts RS256 algorithm, but Supabase JWT key was switched to ECC P-256 (ES256). This causes 401 errors on all authenticated requests. Fix: accept both RS256 and ES256 in the algorithms list, and update tests accordingly.
+
+## Summary of Changes\n\nAdded ES256 to the accepted JWT algorithms in `_verify_jwt()` so ECC P-256 keys from Supabase are verified correctly alongside RSA keys. Added corresponding test with EC key fixtures.
+
+Deployed to production via PR #86 merge on 2026-03-22.
