CI coverage jobs run go test -coverprofile WITHOUT -coverpkg, so each package is measured only by its own tests. cmdcore's logic was exercised only indirectly from internal/helpers, leaving cmdcore self-coverage at 31.5% — failing the CI coverage gate (changed-code 40.5%, overall regression 90.79% to 90.55%) even though the cross-package platform gate reported 100%.
Add direct tests for every cmdcore primitive: flag registration for all four kinds plus hidden aliases/MarkRequired, the explicit-alias-env-default fallback chain incl. Trim/empty skips, integer and slice resolution, required validation, toolArgs assembly incl. Bind/ArgDefault/OmitEmpty/Transform (value, nil-skip, error), constraint declaration panics, constraintProvided (default-not-counted, alias, env, bool, slice main+alias), all three constraint kinds with exact error wording, Risk confirmation (read/--yes/--dry-run/accept/decline), BoolFlag (nil/missing/local/root), schema projection, constraint help, and NewCommand orchestration (order, RunE escape, per-stage abort, decline-cancels, nil dispatch).
cmdcore self-coverage 31.5% to 100%; CI-style changed-code coverage 100%.
