Hold a joining build for a person without superseding its delivery, join only on an engine that keeps own groups, and keep a held module's settings (hq ADR 0328 §8, ADR 0334; re-review of 96e15f86)

A delivery does not send a joining build held for its library or its engine: the module waits for a person, the plan stays open saying so and judges its other modules, and sends it once nothing holds it. A held move is no move for the gate. A module joins only on an engine at contract 7, and a held module is composed with the settings it last ran with. The runner's verdicts are said for their modules and judged by whether a move changes them. mesh-host pinned at #97 (7a41e120), its bundle now examples/foundation-first-node.lock.
Own directories of a joining module carry setgid, to an engine that takes it (hq ADR 0334 v4)

-// **The build agent says whether it is busy, and being asked drains it** (novox/hq ADR 0335 §1, §5). Its

-//   - **no pull request, so no status**: its outcome is never said as `checked`, which is what the forge's
-//     holder sets statuses from (isTry, in Built);

A held move is no move for the gate. A module joins only on an engine at contract 7, and a held module is composed with the settings it last ran with. The runner's verdicts are said for their modules and judged by whether a move changes them. mesh-host pinned at #97 (7a41e120), its bundle now examples/foundation-first-node.lock.	2026-10-13 00:55:54 +02:00

A joining module's directories belong to its user and its own group, and its tools' directories are refused closed to that group; the runner joins it where the engine can say so. A take records the root and is taken only when the engine states the act done.
