v27.6.0

Added

Tier 4 — render.

• disposeIslands(root) on @ultimat3/render/client — release the islands under an element. import { disposeIslands } from '@ultimat3/render/client'. The client router has always called what each island's mount returned when it swaps a page; an island that replaces markup holding OTHER islands (a live list redrawing rows whose menus are islands) had no supported way to do the same and mirrored the hydration runtime's private el.__x. The one function is now public: every island under root, and root itself when it is an island's wrapper, is disposed once its boot resolves; one whose boot never started is settled so it mounts nothing; it works on a detached subtree, and a second call over the same subtree disposes nothing twice. 296 B minified from /client.

Fixed

Tier 0 — core. Tier 3 — realtime. Tier 4 — render, ui. Tier 5 — cli.

• An island that only follows a channel is no longer hidden while it boots. On a signed-in page with a sync node, every island reaching @ultimat3/realtime was held (visibility:hidden, up to 3 s) until it mounted, so an offline reload never painted a count older than a queued write (#506, 25.0.0). An island whose whole realtime use is useChannel, usePresence or useConnection reads neither the record store nor the outbox: there was nothing for the restore to contradict, and the hold only delayed the page's main content. x build now reads which names each module of an island's graph imports from the barrel; an island taking only those hooks (and hasPageSocket, readPresence, channel, channelRef, topic) is not held and its mount no longer waits up to 1 s for the disk restore. Any other name, or a form with no list of names (import * as, export *, import()), holds as before. Nothing to declare.
• With scripting off, a held island is never hidden. The no-script reveal was a CSS animation at the hold's cap, so a reader without JavaScript looked at an empty box for 3 s on every page with a held island. @ultimat3/ui's global.scss now cancels the hold under @media (scripting: none); the keyframes stay as the cap for a browser without that media feature and for a runtime that was blocked.
• A prebuilt image renders the realtime page boot and the holds. Which islands reach realtime was answered by the island build, in the process that ran it. A pod serving a verified island store builds nothing, so it knew of none: no document carried the page boot (the disk restore and the outbox replay never ran from the document) and no island was held, where x dev did both. Each island's answer now rides its own chunk (IslandChunk.realtime, IslandBundle.realtime) instead of process state, the store's index records it, and the document renderer reads it off the bundle it serves; an index without it is stale and rebuilt. Two apps built in one process no longer share an answer for islands at the same relative path.
• A realtime island no longer carries core's and schema's error-title tables. @ultimat3/realtime's error-titles.ts, in every chunk that reaches the barrel, registered through @ultimat3/core's barrel, whose own side-effect anchors are those two tables. It registers through @ultimat3/core/page (which now exports registerErrorCodes) instead: an island whose body is useChannel goes 12,692 B → 8,121 B minified (5,407 → 3,658 gzip), and a built events-only island 21,715 B → 16,813 B. Realtime's own titles are still registered; a core code raised in such a chunk is titled from its name, as on every other @ultimat3/core/page path.
