Cloudflare Workers and Pages already provide the Fetch/Web APIs needed for WebDAV verbs, so the storage integration uses a small local helper instead of adding a Node-oriented WebDAV client. The channel now participates in upload, read, delete, move, rename, channel listing, and runtime config, with chunked uploads explicitly guarded because WebDAV has no portable server-side compose primitive.
Constraint: Preserve Pages Functions and generated Worker deployment paths
Constraint: No new npm dependency for WebDAV client behavior
Rejected: Add a WebDAV npm client | likely Node API/compatibility and package-lock churn
Rejected: Treat WebDAV as External URL only | not a complete storage channel lifecycle
Confidence: high
Scope-risk: moderate
Directive: WebDAV here is third-party storage; keep it distinct from the built-in /dav server settings
Tested: npm test; node worker/generate-routes.js; npx wrangler deploy --dry-run --config worker/wrangler.toml; git diff --cached --check
Not-tested: Live third-party WebDAV provider credentials; Digest-only WebDAV authentication
