Genuinely-open findings from the #1580/#1590/#1591/#1592 reviews (the rest were already fixed on this branch: CSP handlers, manifest version, UUID ids, float keys, presenter 1s-timer): core (#1580): - isManifest rejects a non-object/array manifest (e.g. [42,null]) explicitly - resolveSlideshow flags duplicate slideSequence ids instead of silent overwrite player (#1590): - present() window.open uses noopener,noreferrer (audience syncs via channel) - BroadcastChannel name is per-deck (keyed on pathname) to avoid same-origin cross-talk between decks - add observedAttributes + attributeChangedCallback so runtime sound/mode toggles re-render studio (#1591/#1592): - persistSlideshowManifest no-op gate (skip write when HTML is unchanged) - surface persist failures (console.error) instead of silent .catch(()=>{}) - confirm before deleting a branch sequence (data-loss + dangling hotspots) + tests for the collision + non-object-manifest rejection. 20 core / 106 player / 53 studio pass; tsc/lint/fmt/fallow clean; deck still renders.
