# 2. Git Workflow Linter — Character Set Policy Enforcement ## 2.1. Overview The **[linter_char_scripts.yaml](../../.gitea/workflows/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. --- **[no tracking | no logging | no advertising | no profiling | no bullshit](https://coresecret.eu/)**
