What changes

#/assistant is a system address. The page holds up to three chat threads side by side, from any organization. Each pane reads, sends and updates on its own.
The open set lives in the address: #/assistant?open=<org>:<uuid>,<org>:<uuid>&show=<org>:<uuid>. A reload or a pasted address restores it. A bare #/assistant reopens the last set from localStorage.
Each pane header shows the thread title, the organization chip, the project chip when the thread has one, and close.
A send in a pane goes to that pane's organization, never the one opened last.
A stopped organization is named at the top as not read. Its pane says so, stops reading and keeps an unsent draft. The other panes keep working.
At 390 one pane shows at a time, with a tab strip.
"Open thread" lists threads by organization and can start a new thread in an organization whose config lets this Console send there.
Side by side is removed: panes.js, panes.css and its test are deleted, the sidebar item is gone, and #/side-by-side lands on #/assistant.

How

New assistant.js (MosaicAssistant.mount/unmount/refresh/hasDraft) and assistant.css.
chat.js becomes a MosaicChat.pane(org) factory. The full chat view is one instance of it, so there is one renderer.
display.js system(hash) adds /assistant. Unsent pane drafts count for the organization-switch and Console-restart guards.
No new server route. serve.mjs serves assistant.* in place of panes.*.

Tests

New tests/assistant-threads-browser.test.mjs, 10 tests, written red first.
Lane gate on 789e2bcdd: 188 webui test files, 1472 pass, 0 fail, 4 skipped (org-quick-live, needs a live scratch instance).
Lead check on 789e2bcdd: 95 pass, 0 fail over the changed test files plus the system Tasks, Agents, Inbox, single-pane and org-switch files.
Not tested: the held-draft fixes in 02df2a3a2 (notes 1 and 2) and 789e2bcdd. The fixture cannot turn a composer off while its bus stays healthy. They were checked by reading the code.

Review

Four rounds, each a fresh claude-opus-5-5 reviewer. Round 1 asked for changes, fixed in b98240496. Rounds 2, 3 and 4 approved; their P3 notes were fixed in 02df2a3a2 and 789e2bcdd or are listed below.

Left for later

Project thread links and "open in chat" still open the per-organization chat view, not a pane.
Unused pane and idPrefix parameters remain in projects.js and workspace.js.
No unread badge on the Assistant sidebar item.
Pane drafts are dropped on same-organization navigation and on pane close.
A held draft can be lost if the bus drops while other text is typed.
The held preview cuts on code points, and a comment at assistant.js:254 is stale.

## What changes - `#/assistant` is a system address. The page holds up to three chat threads side by side, from any organization. Each pane reads, sends and updates on its own. - The open set lives in the address: `#/assistant?open=<org>:<uuid>,<org>:<uuid>&show=<org>:<uuid>`. A reload or a pasted address restores it. A bare `#/assistant` reopens the last set from `localStorage`. - Each pane header shows the thread title, the organization chip, the project chip when the thread has one, and close. - A send in a pane goes to that pane's organization, never the one opened last. - A stopped organization is named at the top as not read. Its pane says so, stops reading and keeps an unsent draft. The other panes keep working. - At 390 one pane shows at a time, with a tab strip. - "Open thread" lists threads by organization and can start a new thread in an organization whose config lets this Console send there. - Side by side is removed: `panes.js`, `panes.css` and its test are deleted, the sidebar item is gone, and `#/side-by-side` lands on `#/assistant`. ## How - New `assistant.js` (`MosaicAssistant.mount/unmount/refresh/hasDraft`) and `assistant.css`. - `chat.js` becomes a `MosaicChat.pane(org)` factory. The full chat view is one instance of it, so there is one renderer. - `display.js` `system(hash)` adds `/assistant`. Unsent pane drafts count for the organization-switch and Console-restart guards. - No new server route. `serve.mjs` serves `assistant.*` in place of `panes.*`. ## Tests - New `tests/assistant-threads-browser.test.mjs`, 10 tests, written red first. - Lane gate on 789e2bcdd: 188 webui test files, 1472 pass, 0 fail, 4 skipped (`org-quick-live`, needs a live scratch instance). - Lead check on 789e2bcdd: 95 pass, 0 fail over the changed test files plus the system Tasks, Agents, Inbox, single-pane and org-switch files. - Not tested: the held-draft fixes in 02df2a3a2 (notes 1 and 2) and 789e2bcdd.

feat(webui): sp6, the Assistant page holds up to three threads from any organization side by side, with the open set in the address (#1873 , lane sp6-threads) 5dd940165d

The sidebar Assistant opens one system page, #/assistant. Each pane is the
chat thread view of its own organization: it reads, sends and updates
through that organization's routes, with a header carrying the title, the
organization chip, the project chip and a close control. "Open thread"
lists the threads of every answering organization, grouped by organization,
and starts a new thread in a chosen one. The open set and its order live in
the hash (open=org:id,...&show=org:id), validated on read. A stopped
organization is named at the top and in its own pane; the other panes keep
working. At 390 one pane shows with a tab strip.

Side by side is removed (panes.js, panes.css and its test); its old address
lands on the Assistant page.

fix(webui): sp6 review round, a stopped organization's pane stops reading and keeps its unsent message, an open pane picks up new replies on its own, a pasted thread id in any case shows its pane (#1873 , lane sp6-threads) b982404963

A pane whose organization's bus is stopped or unavailable no longer polls or offers Refresh; it says
nothing is read until the bus starts again, holds any typed draft, and restores it untouched when the
bus returns. Unsent pane drafts now count for the organization-switch and Console-restart guards.
The Assistant sidebar item drops the Messages unread badge. "Start thread" is the primary action.
Tests cover the stopped pane's draft, a reply arriving with no refresh, and an uppercase show id.

fix(webui): sp6 re-check notes, a held message is never overwritten or held out of sight, and a pane whose organization left the list does not promise it comes back (#1873 , lane sp6-threads) 02df2a3a25

The held draft goes back only into an empty composer and is cleared only once it is in it. A thread
that reads without a composer shows the held message in the pane's line. Only a stopped or
unavailable bus says the message comes back when the pane reads again.

fix(webui): sp6 third review round, a held message line stays steady between polls, only a pane's latest render decides the line, the held preview cuts on whole characters (#1873 , lane sp6-threads) 789e2bcdd4
