- `context.params["ROUTE_PAGE"]`: first segment of `ROUTE_PATH`
- `context.params["ROUTE_PATH_RAW"]`: normalized but not trusted route input, for diagnostics only
- `context.params["ROUTE_VALID"]`: `1` when the supplied/defaulted route is safe, `0` when the supplied route was rejected
- `context.params["UCE_BIN_DIRECTORY"]`: writable runtime cache directory from `BIN_DIRECTORY`, useful for generated helper units or other request-local artifacts that must not be written into the source tree
`ROUTE_PATH` is safe to compose under an application-controlled route root. Unsafe route input such as `..`, `.`, empty interior segments, backslashes, dots in filenames, or other non route-segment characters is rejected by the runtime and yields an empty `ROUTE_PATH` with `ROUTE_VALID=0`.
