… from the member The plan's root is a virtual root that holds the values shared by the whole graph. Five statements a member makes about itself were read from that root in 2026.9.29.1 and were therefore empty; the mcpp-index sweep of 2026.9.29.1 found the first two, and an inventory of every read of the root's manifest found the rest (design document section 17.1). - A member's relative [indices].path is anchored at the member when the member is loaded; it was resolved against the workspace root (e2e 120). - The std module is built when a selected member's target entries import std, so a member whose only sources are its tests is tested (e2e 836 M1). - Each selected member's [resources] and windows_code_page are compiled against the member's directory and include directories, under res/<member>/, and embedded into the member's images only (e2e 837). A quoted include or resource file in a script is found through the include directories, as the resource compiler finds it. - [build] linkage is a root-position value. - A member's unknown mcpp: capability is refused, and its cfg() and schema warnings are reported, as a root's (e2e 836 M2, M3).

…9.29.3; ignore the workspace-root build outputs (#488) mcpp 2026.9.29.1 builds a workspace as one graph per configuration and writes the build directory, project data, compile database and lock at the workspace root; these four paths are ignored. 2026.9.29.2 (mcpp-community/mcpp#739) corrects what such a plan reads from its members, among them a member's own relative [indices].path, which 47 members of this index declare, and 2026.9.29.3 (mcpp-community/mcpp#740) places the runtime files of a program shipped through artifacts. - validate.yml pins mcpp 2026.9.29.3; index.toml latest_mcpp -> 2026.9.29.3, min_mcpp unchanged. - The graphics check reads the member's program from its product directory, bin/<package name>/ of the workspace's build directory. The full sweep with 2026.9.29.3 (run 36525705026) passed on every platform.

The plan's root is a virtual root that holds the values shared by the whole
graph. Five statements a member makes about itself were read from that root in
2026.9.29.1 and were therefore empty; the mcpp-index sweep of 2026.9.29.1 found
the first two, and an inventory of every read of the root's manifest found the
rest (design document section 17.1).
is loaded; it was resolved against the workspace root (e2e 120).
so a member whose only sources are its tests is tested (e2e 836 M1).
against the member's directory and include directories, under
res//, and embedded into the member's images only (e2e 837). A
quoted include or resource file in a script is found through the include
directories, as the resource compiler finds it.
warnings are reported, as a root's (e2e 836 M2, M3).
Criteria: each of e2e 120 (member leg), 836 (M1-M3) and 837 fails on the released 2026.9.29.1 and passes on this branch; unit tests IndexPathsAreAnchoredWhereTheyWereWritten, RootPositionValuesSeparateMembers (linkage) and InputsAreResolvedThroughTheIncludeDirectories.
