2. Git Workflow Linter — Character Set Policy Enforcement
2.1. Overview
The linter_char_scripts.yaml defines a declarative policy framework for sanitizing and validating character scripts within a Git repository. It enforces linguistic and typographic constraints at the commit level, preventing the introduction of ambiguous, non-printable, homoglyphic, or non-standard Unicode character classes. This mechanism enhances both the integrity and auditability of the codebase, particularly in contexts where multilingual input, identity obfuscation, or supply-chain risk (e.g., Trojan Source attacks) must be mitigated.
2.2. Purpose
The core intent of this linter is to:
- Detect forbidden Unicode scripts or codepoints within staged files.
- Ensure locale-hygienic commits by permitting only explicitly whitelisted language/script groups.
- Enforce character uniformity across source files, configuration, and metadata.
- Block malicious or ambiguous glyph injection, including bidirectional override, homoglyph attacks, or zero-width characters.
2.3. Security Considerations
This linter serves as a preventive supply-chain control by reducing exposure to:
- Invisible character injection (e.g. \u200e, \u202e)
- Homoglyphic substitution (e.g. Cyrillic а vs. Latin a)
- Bidirectional override attacks (Trojan Source)
- Untraceable backdoors hidden in user comments or unused string literals
It complements traditional static analysis and code review processes by operating at a syntactic level of representation, thus neutralizing attacks that bypass semantic inspection.
2.4. Conclusion
The linter_char_scripts.yaml is a vital component of the CISS.debian.installer secure development lifecycle. It defines
a robust, extensible, and policy-driven control layer against linguistic abuse and typographic ambiguity in version-controlled
assets. Its utility is especially salient in multi-language environments, cryptographic infrastructure code, and supply-chain
sensitive repositories.
