- Read STEALTH_CURSOR_SECRET via a defensive cast (not declared on the Cloudflare env type) so an undeclared secret fails the validation gate instead of a type error. - Restore the KV/coordinator presence guard so HybridApiRepository receives non-undefined bindings (narrows KVNamespace | undefined).

Goal
Validate required environment bindings, secrets, supported versions, and storage adapters at startup / first initialization so misconfigured deployments fail clearly before serving partial or unsafe API behavior (issue #1516).
Changes
src/server/api/context.ts: extractvalidateApiConfig()— enforces KV + coordinator bindings, the cursor secret, and at least one supported version in production; distinguishes dev vs prod; never logs secret values.getApiContext()calls it before constructing the production repository.tests/unit/api/config-validation.test.ts: valid dev, valid prod, missing KV/coordinator/secret in prod, no secret leakage in error messages, empty supported-versions, and dev bypass.Verification
npx vitest run tests/unit/api/config-validation.test.ts→ 8 passed.npx prettier@3.8.5 --checkclean on changed files.Fixes #1516
