Description

Currently we don't support backtracking in targets or deps to reference paths outside of the folder with the chompfile.toml root. This makes it impossible to do mtime-based comparisons for operations outside of the chompfile therefore requiring cross-project tasks to be re-run everytime and instead require their own invalidations.

Just adding support for arbitrary backtracking in targets and dependencies might be a good start for cross-project validations.

Further support for building multi-chompfile graphs based on treating files as "belonging to" their parent chompfile might then further provide something like a monorepo support.

Worth fleshing this out further and carefully considering the consequences, but it could be worthwhile if there is interest.

Research direction

Start by reviewing how targets and dependencies in chompfile.toml resolve paths relative to the project root. Define the scope for arbitrary backtracking and decide whether multi-chompfile graph support is included; document the consequences and acceptance criteria before implementation.
