Unchanged / 0-impact measurements (6)These rows had compatible baseline data, but their semantic impact rounded to 0.00x because the movement was below the configured budget, below the noise floor, or inside the robust noise band. devenv / devenv cli

There was a problem hiding this comment.
When this artifact is imported on a standard NixOS host, the resulting mr executable cannot start because NixOS does not provide the FHS loader at /lib64/ld-linux-x86-64.so.2; removing the existing RPATH also discards the Nix-provided shared-library locations. This conflicts with the new Nix import path, whose platform check accepts generic x86_64-linux. Package an appropriate loader/libraries with the artifact or patch the executable during Nix import while retaining the required runtime references.

Warning
STALE PROTOTYPE / SALVAGE SURFACE. This branch conflicts with the canonical #1056 head and predates the strict shared-product contract. Its prior green CI is not current admission evidence. The normalized TypeScript materialization and product-specific commits will be replayed into the topology tracked by #1050 and #1051.
Stacked on #1056.
Outcome
This makes
//packages/@overeng/megarepo:mrthe first real repo-local Buck build target. Buck owns a generated project-reference typecheck plus a separate exact first-party Bun runtime graph, produces a deterministic standalone archive and provenance descriptor, and passes that immutable artifact through the existing digest/platform-verified Nix import bridge.Boundaries
