Temporary probe for W8 (design 2026-11-08): the e2e cases of one Linux shard run 1, 2 and 3 at a time by mtest 0.2.0 (wall time and failures against the serial harness); mcpp's unit tests as a program per file and as a program per directory ([test] programs = "directory"); and the edges a build runs again over a target/ taken over from another checkout, with and without the sources' times. It asserts nothing.

…rkspace, as under -p

A workspace's test plan holds a member's test programs only, so its own programs were never built
and its tests found no MCPP_BIN_<NAME>. Each member's programs are built by the member's plan and
named to that member's tests. Found by mtest's conformance suite.

The built-in platform is openkal-platform 0.24.4

openkal-image 0.5.3 enters an image in its convention's floating-point
state (openkal SPEC 12.2); on Windows a thread began with the x87 at
double precision, under which openkal-musl's strtod read 0.4 otherwise.

feat: mcpp test runs the runner's side of the test protocol
e8f5738
A test program that implements the mtest test protocol, version 1 -- its
entry states test-protocol = 1, or its file carries the marker -- is told
the protocol's variables and reports its cases: a run's record names the
protocol and each case's result and failures, a case a crash left open
failed, and the human report names the failed cases. --case PATTERN runs
the matching cases, --cases lists them, --seed states the seed. A program
that implements no protocol is one case and receives none of the
variables. --no-run records each built test with its program and sources.

Every accessor reads through value_of: the innermost context's values,
then the environment. A test of a build program's or a plugin's logic
states the values in its own process. (e2e 1036)

…ers to begin a test with no main

The skeletons' test is a file of mtest's cases with no main and the
dev-dependency mcpplibs.mtest; --template lib writes a module, a partition
it exports and its implementation, named after the package. An entry with
test-main = true begins a test file that defines no main; the file's
imports choose among offers, a dev-dependency's source that defines main
(gtest_main.cc) begins a test as before, and two beginnings are refused.

An entry states its guide to writing tests with test-guide (the protocol's
P2.5). --guide lists the package's frameworks with their guides and
repositories and the commands for cases, or the contract and mtest when
there is none; a failed run's report names it and a record carries guide.

…are one configuration

A dev-dependency's include directories and definitions are given to the files under tests/, and a kernel interface only a dev-dependency reaches is given to the dev-only packages and the test units. The package's own sources compile under mcpp test with the commands mcpp build gives them. A source beneath the dev-dependencies that defines main is the one a test with a beginning leaves out; a C library's start-up file is not (docs/08; e2e 1037 K).
