These scripts provide lightweight, portable validation for project records. They do not replace source review or research judgement.

• validate_proposal_ledgers.py checks the project template and every candidate proposal requirements ledger for structural drift, stale cut-off indicators, broken local links and fragments, missing support, incomplete readiness summaries and possible public e-mail addresses.

Run it from the project root with Python 3.10 or later:

python3 scripts/validate_proposal_ledgers.py

Treat warnings as failures for a pre-commit check:

python3 scripts/validate_proposal_ledgers.py --warnings-as-errors

The validator uses only the Python standard library. Its tests use unittest:

python3 -m unittest scripts/test_validate_proposal_ledgers.py

In regular expressions, prefer a character class to alternation for single-character choices. In verbose mode, use insignificant horizontal whitespace to expose token boundaries, as in < (?P<name> [^>]+ ) >, and format dense nested groups or alternatives vertically; add line breaks for structure, not for every token.
