mesh/check pass d739516056dd on 55a506975b01 | unit 7056 run, 243 kept, 16 skipped | integration 7194 run, 275 kept, 25 skipped | over bound: unit, in… 
A check ask named no toolchain, so a node on the minority version could run it and KeepPasses record the pass as run on the agreed one. The check ask now carries the agreed toolchain and a node off it declines (mesh-sdk), for the checker's decline loop to put again. Pins the builder, indexer and checker.

Known limit: the checker puts a declined check ask again at once, with no pause; the declining puller skips that kind until its next pull wait, which paces a lone minority node.

jschoubben a6c225eb45 Pause before a declined ask is put again with a context's bound, not a timer (ADR 0437 §8, issue 1578) 
The builder's manifest test refuses time.After. The previous commit's pause used it.

jschoubben 5085b681e9 Count no decline as an asking; bound declines by time and name the nodes (ADR 0584, issue 1578) 
A build node off the agreed toolchain declines the ask and, idle, takes the ask put again at once, so three declines used the three askings and failed the build. A decline now uses no asking: the ask is put again after a short pause, and past a bound from the first decline the key fails naming the declining nodes and their reasons. A person reads which node sits out in the key's step text, which the view's builder_builds answers as stored.

jschoubben 9e407f8f76 Build with the toolchain a majority of build nodes report; say which nodes sit out (ADR 0584, issue 1578) 
One build node on another version refused every build of the language. The builder and the checker now follow mesh-sdk's majority agreement; the key's step names a node that sits out ("ace sits out: typescript 26.12.1, agreed 26.13.0"), and a build ask a minority node declined is put again for a node on the agreed version. Check steps compare no toolchain, so clause 2 already holds for them. Pins builder, indexer and checker to mesh-sdk 71be15f.

jschoubben 8545e7fc9f Cite ADR 0584 where the builder waits on a toolchain the nodes do not agree on (issue 1578) 
Comment only; the majority rule itself is in mesh-sdk's AgreedToolchain.
