In Bot Mode every roster click resolved the bot's canonical "Bot Chat" by
name and opened it as a tab. Nothing records a tab close (the plugin keeps no
closed set; core's tile bucket only forgets), so a Bot Chat the user had
closed came back beside every newer thread on every bot switch — close it,
start a new thread, visit another bot, come back: two tabs again, forever.
A row click is now "go to this bot": when the bot's workspace already holds
tabs, the one the user last had active is fronted and no chat is resolved or
opened. The canonical chat is opened only when the bot has nothing open, or
on the explicit asks — a new "Open Bot Chat" row-menu item and the Bots home
"Open chat" button (`openRosterBot(bot, { canonical: true })`).
- session-states: `focusWorkspaceOwnerSessionTile(ownerKey)` fronts the
owner's remembered-active tile (else its most recent) and reports it.
- sdk: `host.focusOpenWorkspaceSession(ownerKey)` exposes it to plugins;
feature-detected in the plugin so older shells keep the canonical open.
- hermes-bots: `focusExistingBotTab` short-circuits `openRosterBot`; the
claim it records carries only the fronted tab, and the session.reclaimed
re-resume now skips such claims so it cannot resurrect the closed chat.
Tests: vitest for the core helper, a node test for the click path (open tabs
win, nothing open → canonical, explicit canonical, older shell, throwing
host), and an e2e that seeds two bots with real "Bot Chat" rows, closes one,
starts a thread, switches bots and back, and asserts the Bot Chat stays
closed until asked for explicitly.
