Investigated whether two admin browsers open at once can overwrite each other's changes, per an explicit request to report the risk before making bigger changes. Found that POST /api/state always replaces the entire stored document with a client's in-memory copy, with no version check and no per-field merge - and a browser only ever pushes, never re-fetching server state after page load except on the Overlay view. An idle browser's next save, even an unrelated edit, could silently revert another browser's more recent changes, worst case a live race's in-progress results. Two scoped fixes instead of the bigger optimistic-locking rework (that needs real UX decisions about conflicting saves, deferred separately): 1. server.js now remembers which session results were just written by a real live decoder passing (/api/passings) and protects that key for 15 seconds against being reverted by a stale full-state save, while still applying the rest of that save normally. 2. Every non-Overlay view now quietly refreshes its data in the background every 15 seconds (skipped while a local edit is pending), without ever calling renderView(), so it can never discard an open, unsaved edit form - shrinking how stale a browser's next save can be from hours to seconds.
