# 1. CISS.debian.installer

**Centurion Intelligence Consulting Agency Information Security Standard**<br>
*The CISS Debian Installer provides a fully automated and hardened installation process.*<br>
**Master Version**: 8.00<br>
**Build**: V8.00.000.2025.06.17<br>

# 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.
