Nitro's built-in route cache (defineCachedEventHandler) forwards its already-caught best-effort KV write failures to Sentry as unhandled errors (SKILLD-17, KV PUT failed: 429), while project policy in shared/server/cache.ts records the same failure class as a wide event, so the server Sentry config needs a beforeSend filter for this exact signature with the wide event kept as the visibility path.

Target: shared/sentry.ts + server/plugins/sentry.ts

Verify with: pnpm test:run test/unit/sentry-cache-write-filter.test.ts

Route: Ready to implement
Difficulty: 2/5
Impact: 3/5
Reproduction: Yes
Codebase review: Not needed
Summary: Verified end to end in installed deps: nitropack 2.13.4 runtime/internal/cache.mjs catches its route-cache KV setItem failure and calls useNitroApp().captureError(error, { event, tags: ['cache'] }); @sentry/nuxt 10.73.0 sentryCloudflareNitr
Next action: Implement isBestEffortCacheWriteError in shared/sentry.ts matching the exact best-effort cache-write signature, wire it as a beforeSend filter on the sentryCloudflareNitroPlugin options in server/plugins/sentry.ts, and add test/unit/sentry-
Fix with: sentry-checkin: nitro cached-handler SWR writes to the KV_CACHE mount exceed the 1 write/sec per-key limit and captureError raises each rejected best-effort write as an error even though the request succeeds, so SKILLD-17 and SKILLD-1V are recurring noise #124

fix: resolve issue #117 (#153)

Fixed by #153 (merged 2026-09-07): nitro route-cache KV write failures are dropped in beforeSend.
