## 2024-11-20 - Use Zsh Native Extended Globbing for File Staleness
**Learning:** Checking file age by spawning `stat` and `date` as subprocesses adds unnecessary overhead and degrades shell startup performance. In this codebase, avoiding subprocesses is a critical optimization pattern.
**Action:** Use native Zsh extended globbing (e.g., `(#qN.ms+seconds)`) coupled with `setopt local_options extended_glob` to perform file age evaluations natively within the shell, bypassing process spawning altogether.

## 2026-07-22 - Znap Automatically Handles compinit
**Learning:** The Znap plugin manager automatically handles `compinit` and comp dumps out of the box. Manually calling `compinit` (e.g., in `.zshrc` or `zsh/znap.zsh`) degrades shell startup performance due to redundant execution and should be avoided.
**Action:** Do not manually call `compinit` when using Znap for plugin management to ensure optimal shell startup performance.
