+### Task 9: Migrate router rules from v2 to v3 syntax
+
+**Why:** The `--core.defaultRuleSyntax=v2` flag is deprecated in Traefik v3.4 and will be removed in the next major version.
+
+**Deprecation Warning:**
+```
+`Core.DefaultRuleSyntax` option has been deprecated in v3.4, and will be removed in the next major version.
+Please consider migrating all router rules to v3 syntax.
+```
+
+**Migration Guide:** https://doc.traefik.io/traefik/v3.6/migration/v3/#rule-syntax
+
+**Steps:**
+- [x] Review migration guide for v2 → v3 rule syntax changes
+- [x] Audit all router rules in docker-compose.yml labels
+- [x] Audit all router rules in `/mnt/docker/traefik3/rules/*.yml`
+- [x] Update `HostRegexp` rules to new syntax (backticks → template syntax)
+- [x] Update any `Host` rules if needed (none needed - all Host rules are v3 compatible)
+- [x] Remove `--core.defaultRuleSyntax=v2` flag from docker-compose.yml
+- [x] Test all services after migration
+- [x] Run validation script to confirm no regressions
+
+**Known v2 → v3 Syntax Changes:**
+- `HostRegexp(\`{host:.+}\`)` → `HostRegexp(\`.+\`)`
+- Backtick template variables may need updating
+
+**Priority:** Medium - Should complete before Traefik v4 release
+
+---
+
+### Task 10: Investigate Permissions-Policy header not appearing
+
+**Issue:** Despite correct configuration in `/mnt/docker/traefik3/rules/middlewares.yml`, the `Permissions-Policy` header is not present in HTTP responses.
+
+**Root Cause Identified:** Synology NFS caching issue
+
+**Investigation Findings (2026-01-24):**
+- [x] Verified Docker NFS volume correctly points to `/volume1/docker/traefik3`
+- [x] Confirmed file content inside container is correct via `docker exec traefik cat`
+- [x] Traefik API consistently shows OLD configuration (featurePolicy, sslRedirect: true)
+- [x] Even after volume recreation and container restarts, Traefik reads stale data
+- [x] Added explicit `Permissions-Policy` header in `customResponseHeaders` as workaround
+- [x] Workaround also affected by the same NFS caching issue
+
+**Current Configuration (correct in file, not read by Traefik):**
+```yaml
+permissionsPolicy: "camera=(), geolocation=(), microphone=(), payment=(), usb=(), vr=()"
+customResponseHeaders:
+  Permissions-Policy: "camera=(), geolocation=(), microphone=(), payment=(), usb=(), vr=()"
+```
+
+**Resolution (2026-01-24):**
+- [x] Issue resolved after Task 8 container restart cleared NFS cache
+- [x] Permissions-Policy header now appearing in all responses
+- [x] Validation script confirms 26/26 tests passing
+
+**Priority:** Low - Non-blocking security enhancement
+**Status:** ✅ RESOLVED - NFS cache cleared during Task 8 container restart
