jschoubben	cadd7b1b2f	Ask the vault in a candidate answer only for credentials of modules the node runs, and refuse a stand-in of a running module, so a placement that adds a module is answered as added (issue 1126, ADR 0559 §4)	2026-10-27 02:43:10 +01:00
jschoubben	062c29c3a2	Judge a node's own composition in its candidate answer only where it runs one, as its agent applies it only on a want (issue 1126)	2026-10-27 02:27:04 +01:00
jschoubben	a37d2622ed	Name the words of a composition failed only for an answer not heard, and what an answer's revision is, so the assigner and the checker judge a late answer alike (issue 1126)	2026-10-27 02:22:59 +01:00
jschoubben	ba398e2460	Answer a placement candidate as ADR 0559 has it: added and removed modules, per-module refusals, both digests of a difference, and a node's read of every candidate key (issue 1126)	2026-10-27 02:19:27 +01:00
jschoubben	82f10c3bc9	Let frombus and the composer compose with a given placement and compare a node's compositions with what it runs, so a placement candidate can be answered and checked (issue 1126)	2026-10-27 02:12:11 +01:00
jschoubben	7e99c354ac	Give a catalogue pull request's placement a candidate state and each node an answer in its own have, so a placement change is checked by the nodes it places before it merges (issue 1126)	2026-10-27 02:07:47 +01:00
jschoubben	8e81d87610	Let a replicated mesh seat be held on several nodes in CheckPlacements, so the seed of today's placement is not refused (issue 1126)	2026-10-27 02:04:01 +01:00
