git mv packages/business -> packages/organization (@mosaic/organization). The
old package stays as one-line re-export shims of each moved module, with
src/business.mjs re-exporting src/organization-config.mjs and src/cli.mjs
forwarding to the moved executable. BusinessError is OrganizationConfigError
(one constructor, name kept BusinessError); OrganizationError stays distinct.
The bus adapter gains organization-context.mjs (busOrganization), with
business.mjs (busBusiness) as the same function.
Import consumers, manifests, the lockfile, scripts/mosaic, stack-copy.sh
COPY_PATHS (both roots), seat sandbox RUNNER_FILES and the copy closure
walker (organization-imports.mjs, both roots required) move to the new path.
v1 serialization, v1 writers and the stage A fixtures are unchanged; the stage
A contract tests stay where they were and pass as before.
The cli tests that launch pi deleted only the session login names, so pi's
preflight passed or refused by whatever provider keys the host exported. A
shared helper now deletes every credential pi's preflight reads and gives pi
launches one made-up key. The refusal itself is unchanged.
pi bundle() takes a default argument again, so a call with none returns the
non-proxy bundle, as before P3. pi.bundle leaves out a launch.models entry
whose provider has no proxy route instead of failing every pi launch (F2);
malformed proxy entries still refuse. The invalid session proxy context
BundleError gets the code invalid-proxy-context. New tests cover F2, the code,
and the three proxy account branches in the launcher (F3).
A halt inside the op reaches the bus's own fence first (runtime.mjs:564-566,
processingWork at :352-356), so the launcher refused limit-check-failed
(launcher.mjs:389-391) before its recheck admission() at :397. First-run red of
a new test on 6d9ab3503 early signal, placed under mos-1272.
The section "recover() change, for a design read" covers three things, with
file:line against aca16404c. Every leftover is still bound and ended as
host-lost, and a survivor only refuses legacy-run-live while it lives. The
5 s wait applies only in the bwrap kill branch. No old test's expected value
changes. The fallback is to revert to the base recover() and leave the
refusal untested. The survivor log line now names the outer and runner pids
so an operator can clear it, and the new test's log assertion matches.
recover() kept a survivor only when a bwrap outer pid outlived SIGKILL, so
the Q2 refusal (BUILD.md:177-179, t1-sessions.md:109) had no test. A leftover
whose runner still ran after its outer pid was gone was ended and dropped.
Now recover() waits on the outer pid and the runner, keeps any leftover where
either still runs, and logs that it still runs. check() reads only the
survivors that still run.
session-launch.test.mjs adds a test where a sessionless leftover's runner is
a sleep child and its outer pid is gone. It asserts the legacy-run-live
refusal with no launch and no session workspace, then one launch once the
child exits. BUILD.md adds mutants M10-M12 and replaces the "no test" note.
threadsState gives one row per session with `session` and `legacy`; threadIdle
idles a run against its bound session. Each session gets its own store
(threads/<b>/<t>/sessions/<s>/, or the thread's old store for a legacy-3l
session) and its own workspace (session-workspaces/<b>/<i>/<s>/), held by an
O_EXCL <ws>.lock from before the clones to the run's proven exit. A legacy
session's workspace binds in-sandbox at the old instance path. sessions.json
is v2 and reads v1. New tests: cli session-launch.test.mjs, seat
session-workspace.test.mjs. Not yet run: tests wait for Sage's CLEAR.
Two old assertions change as exact updates:
- mos-1285: end-launch.test.mjs threadsState deepEqual. The old row shape was
{ thread: 'th-1', instance: 'coder', pending: 0, unread: 0, lastMessage: null,
lastOpen: '2026-10-15T00:00:01.000Z', lastClaim: null, holder: null }; the
row keeps every key and value and adds session: 'th-1', legacy: true.
- mos-1289: thread-launch.test.mjs:182, old line
`const store = join(f.dataRoot, "threads", "acme", A);`
now reads A's default session id from threadsState's `session` key; :183-185
unchanged; one added assert that threads/acme/<A>/session is absent.
