Preflight

Run preflight in the validate step, before the project's own validation command.

.agents/skills/preflight/scripts/preflight              # vs the default branch's merge base
.agents/skills/preflight/scripts/preflight --staged     # staged changes (pre-commit)
.agents/skills/preflight/scripts/preflight --all        # every tracked file, every line

Fix what a finding reports; never widen a lane's exclusions to clear it.

Lanes, scopes, settings, output and exit codes are in preflight --help. Diff construction and the unwired-suite, data-syntax, applied-migration-edited and fail-open sourced-library glob grammars are references/lanes.md. Hook and CI wiring is README.md § Wiring.
