 ## 2025-07-17 - Grouped I/O in scripts/init.py
 **Learning:** Performing multiple consecutive file reads/writes on the same files (`pyproject.toml`, `mkdocs.yml`) causes redundant disk I/O overhead.
 **Action:** Group file modifications by file path to perform exactly one read and one write operation per file.

+## 2025-07-17 - Batch Git Config Subprocess Invocations in scripts/init.py
+**Learning:** Sequential `subprocess` querying of Git configuration parameters (`user.name`, `user.email`, `github.user`) during interactive CLI initialization is slow (~3x overhead). Running a single batch subprocess query via `git config --get-regexp` and caching the result reduces the initialization delay significantly. Additionally, using an initialization flag prevents redundant subprocess calls when all configs are missing (e.g. in empty or CI environments).
+**Action:** Cache git configuration queries globally on first use with an explicit initialization flag.

+## 2025-02-14 - Supply Chain Hardening via Action Pinning & Least-Privilege Permissions
+**Vulnerability:** Workflows referenced a mutable and non-existent version tag (`@v7`) for `actions/checkout` and lacked explicit token permissions, leaving them open to potential tag-hijacking supply-chain attacks and overly permissive default GITHUB_TOKEN write access.
+**Learning:** Using tags like `@v4` or `@v7` is insecure because tag references are mutable and can be modified or spoofed by malicious actors in the upstream dependency repository, leading to code injection during CI/CD runs.
+**Prevention:** Always pin third-party GitHub Actions to their secure, immutable full-length commit SHAs and explicitly restrict permissions to `contents: read` at the job level.
