 **The cycle's rules, at the write** (hq playbook 03, which `00-META/checks/cycle.py` enforced on the
-folders until the import): a status is one of `open`,
-`diagnosing`, `located`, `resolved`, `wontfix`; `located` needs `located-in`; `resolved` needs
-`located-in` and `fixed-by`; a core issue (located in the controller, the node-engine, the tool runner,

+`diagnosing`, `located`, `fixing`, `resolved`, `wontfix`; `diagnosing` and `fixing` need `by`; `located` needs
+`located-in`; `resolved` is reached only from `fixing` and needs `located-in` and `fixed-by`; a core issue (located in the controller, the node-engine, the tool runner,
 the SDK, or the catalogue's bus, forge or build agent) resolves with `replay` or `replay-none`; `wontfix`
 needs a `reason`. A refused change changes nothing and says which rule refused it.
 
+**Who works on it** (hq ADR 0283). A move to `diagnosing` or `fixing` names in `by` the issue's **worker**: who
+works on it and its node, as `who@node` (such as `fix-399@g14` or `jochen@shanks`, kept in lower case). The issue
+keeps its worker (`worker`: `by`, `since`, `active`) while it stays at either status; any other status ends the
+work. `get` shows it, with `worker-stale`, and each `list` row shows `worker`, `since` and `stale`. A move to either
+status by someone else while the worker is current is refused, naming the worker; with `take-over` saying why, the
+issue is taken over, and the reason is noted on it. A worker with no move, note, link or set from a caller on the
+issue for `worker-stale-after` (default `24h`) is stale and may be taken over from without a reason, still noted.
+The tracker's own writes (the triage, the duplicate check, the delivery notes) keep no worker current. The `moved`
+event carries `by` (the worker; who acted, for a move naming none), `since`, `caller` (who acted, as the runtime
+proves it: `unproven` today), and `took-over-from`, `take-over` or `released` when they apply. `by` is what the
+worker says it is: the runtime does not yet tell a module its caller (hq issue 340), so the worker lets agents and
+people see each other; it is not a lock against a false name.

 **An issue with a folder in hq** (`record` at open: the folder's name, without the number) is whole in the
