Builds on the salvaged #88598 multi-source roster work:
- New Agent "Create on" picker (multi-connection registries only): the
profiles.create/configure/describe/mcp.catalog calls route to the picked
connection's backend via host.requestProfile route descriptors — the
window's active gateway never switches. Remote-target drafts discard via
the remote CLI; appearance/title write into the remote profile's ui_meta
and asset store; the taken-name check is scoped to the target machine's
roster; the live SkillsView Capabilities tab (active-gateway-bound) falls
back to the staged checklists for remote targets.
- Group chats can seat bots from other registered connections: member turns
(session.create/resume, prompt.submit, reply polling) route to each
member's own source through the new requestForBot helper. Remote member
descriptors persist on the room record (bot-meta is active-gateway-scoped
by design); watermarks/sessions key by source-qualified member keys so
same-named agents on two machines never share state; @name-device handles
resolve in room mentions; room lines and turn prompts badge cross-machine
speakers with their device.
- pidIsOurDashboard: a dead remote PID (ps exits non-zero) now reads as
FOREIGN instead of throwing "Could not verify SSH backend process
ownership" — the misleading error from #88625's secondary report.
Tests: cross-connection-bots.test.mjs (route descriptors, requestForBot
routing, member keys, disambiguated mentions, device badges, source
contracts); plugin suite 180/180; electron vitest 220/220.
