Resolve controls with a form= attribute inside the current slhx root instead of using document-global id lookup, preserving multi-root isolation for direct handle dispatch.
req: runtime/001
req: convention/004
Cover that runtime updates use generated slot/resource ids and do not expose response-side retargeting or CSS fragment selection conventions.
req: target_policy/001
req: target_policy/002
Cover multipart runtime request construction so file-upload forms keep FormData, omit File values from URL encoding, and only mark URLSearchParams bodies as urlencoded.
req: multipart/003
Cover data-slhx-every runtime behavior: root scanning, duplicate timer avoidance, interval dispatch, and cleanup when elements leave the document.
req: convention/005
Send interaction and page-swap fetches with same-origin credentials so cookies/session/CSRF context stay available to integration-layer policy without broad CORS behavior.
req: auth/005
Assert the browser runtime refuses stale partial/effect updates when deployment fingerprints mismatch and falls back to reload instead of applying stale ids.
