Row 92, round 2. Darkwing built it. A role session runs in a bwrap
sandbox that sees only its own workspace, a private /proc, /dev and IPC
namespace, and the variables ENV_ALLOW passes. The launcher checks the
session credential before a Claude launch, records a runner killed from
the host as killed rather than failed, and the bus unit template carries
the credential file (decision 119). The harness gate and the cli, seat
and harness READMEs say what the sandbox does and does not hide.
Candidate manifest 8bf4141cbe69fc7bed188555bcc88dcab0b1ea2149912cb6f970ba8c2629dd97
(13 paths), base ac37cd17, packet agents/darkwing/work/queue-92/r2/.
Approvals: Dewey 27978, Filbert 27984 (round 1: Dewey 27942, Filbert
asked for changes in 27951). Sage's gate rerun 22:27:37Z-22:30:35Z on
1b7f3781 plus the patch, manifest 13/13: seat 33, cli 120, harness 65,
bus 108, webui 86, control-board 124, and every scripts/test-*.sh exited 0
(test-release 4, Docker cases skipped at a dead socket).
Live at the next bus restart and the next role session launch (decision
109). Installing the new unit and restarting is Mos's call.

Slice 1 S6. packages/harness runs a role session under the pi or claude
adapter behind a tool gate, and packages/seat holds the session and its
process. The bus host gains a launch socket: `mosaic bus start
<business> --pm <harness>:<model>` runs the PM without a window, the PM
launches role sessions through the broker within the business file's
`launch.max`, and every launch, refusal and end is a launch-log line and
a broker event. `mosaic talk`, `mosaic launches off|on|list` and
`mosaic stop <run>` are new CLI verbs. packages/bus gains the IPC ops
identity, authorize, refuse, endLaunch and credentialStatus, plus
Broker.endLaunch (decision 77); no socket verb, event kind or schema
changed. The session environment is an allowlist, and the runner exits
before claiming if a founder credential reaches it.
Filbert built it (agents/filbert/work/s6). Darkwing reviewed on #1523:
round 1 changes (26991/26995), round 2 changes (27004/27010), round 3
changes (27012/27032), round 4 approve (27033/27034) on manifest
08a78972, 42 paths.
Sage's gate on 64b0f9f1 (12:32Z), sequential and teed: node suites
business 60, bus 74, cli 83, control-board 124, conversation 182,
discord 178, harness 56, ledger 78, mosaic 69, queue 149, runs 41,
seat 27, tasks 51, webui 39, every one 0 failed; test-auth 15,
test-conductor 17, test-config 24, test-discord 66,
test-extension-package 18, test-foundation 44, test-queue 27,
test-release 14, test-task 98 and 26 without Docker, all 0 failed.
64b0f9f1..ee7f909b touches none of the 42 paths. It landed after the
Q14 hold ended at 2026-10-11T17:19:23.857Z. The recorded PM-to-coder
run on a scratch data root is still owed before row 41 moves to done.
