Review posted successfully to PR #14640.

Summary of the actionable issue found:

Dry-run / inherit handling missing for draft flagship bindings (create-worker-upload-form.ts:436) — The new flagship branch omits the dryRun guard (app_id ??= INHERIT_SYMBOL) and the INHERIT_SYMBOL → { type: "inherit" } handling that every other provisionable binding (KV/R2/D1/AI Search/Agent Memory) implements. This breaks wrangler deploy --dry-run for exactly the draft-binding case the PR adds (throws "must have an app_id field"), and can serialize a Symbol into metadata via the FlagshipAppHandler.inherit() → super.inherit() fallback path. Posted with a suggestion to mirror the existing pattern.
