The controller imports mesh-host/validate through a replace onto the forge that holds it, and every build — the build agent's go build in a fresh toolchain container, the Dockerfile's go mod download — would have fetched it through the public proxy and checksum database at build time: a merge breaking main on the network, the class Phase 1 removes. vendor/ is committed; go builds from it with nothing fetched, and refuses to build when it and go.mod disagree, so a pin moved without go mod vendor fails at once. The Dockerfile copies vendor/ and builds with GOPROXY=off.

|
// the following sub-rules.
|
|
//
|
|
// a. Map any instances of non-ASCII space to SPACE (U+0020); a
|
|
// non-ASCII space is any Unicode code point having a general
|
|
// category of "Zs", naturally with the exception of SPACE
|
|
// (U+0020). (The inclusion of only ASCII space prevents
|
|
// confusion with various non-ASCII space code points, many of
|
|
// which are difficult to reproduce across different input
|
|
// methods.)
|
|
//
|
|
// b. Remove any instances of the ASCII space character at the
|
|
// beginning or end of a nickname (e.g., "stpeter " is mapped to
|
|
// "stpeter").
|
|
//
|
|
// c. Map interior sequences of more than one ASCII space character
|
|
// to a single ASCII space character (e.g., "St Peter" is
|
|
// mapped to "St Peter").
