The factory profile of scripts/case2-unit.sh now takes the bare pair
--sso --send, ported from the lane's serve_flags rule (b00019548). Either
flag alone refuses, and the proxy preview set and the proof pair still
refuse. Before any unit write, a bounded query run as the stack user,
through the existing config-query supervisor, checks that the stack
user's system config has console.sso; the Console refuses --sso without
it at start (packages/webui/src/cli.mjs:95). The server needs no change.
The library profile is unchanged: still read-only, still refusing --send
and --sso. Taking library --send with forward-auth and proof would need
the #385 refusal reverted in cli.mjs:63, serve.mjs:681 and the service,
release and upgrade scripts, so it is not done here.
docs/guides/case1-business.mosaic-stack.json now launches
claude-opus-5-5 with provider proxy, route anthropic, under account
factory with credential proxy.
