+// The Worker-side bounds that @loopover/contract restates must equal their originals (#9773 follow-up).
+//
+// WHY THIS EXISTS. limits.ts says these entries are "pinned against their originals like every other entry
+// here" -- but PREFLIGHT_LIMITS was the only group with a meta-test actually doing the pinning. The three
+// single constants were restated on trust, which is the same thing as not being pinned.
+//
+// The failure this catches is quiet and one-sided: the contract package cannot import the Worker's `src/`
+// (it is a zod-only leaf, which is the property every other surface depends on), so nothing at compile time
+// relates the two copies. Raise a bound on the Worker side alone and the published schema keeps rejecting
+// input the server would now accept; lower it alone and the schema accepts input the server then rejects or
+// truncates. Either way the mismatch surfaces as a confusing client-side validation error rather than as a
+// build failure.
+//
+// This is not a hypothetical. gen-contract-api-schemas.ts copies these schemas verbatim, so a copied schema
+// referencing a constant that has NOT been restated here emits a file that does not compile -- the
+// generator's own doc calls that "the loud failure this wants". #9738 added
+// `.max(MAX_PRIORITY_ELIGIBILITY_WINDOW_MINUTES)` to the settings schema without adding the constant, which
+// left `main` failing `contract:api-schemas:check` for every PR: regenerating produced an uncompilable file,
+// and not regenerating left the check red. The constant is now restated; this test is what keeps the VALUES
+// together from here on, which the compile-time failure alone never did.
