- Replaced `cat | sed | tr` pipeline with `tr < file` redirection.
- Eliminates 2 unnecessary process forks per file processed.
- Fixes a critical bug where `sed 's// /g'` caused data loss (empty output) for all files.
- Improved performance and reliability of content extraction.

+## 2025-12-20 - Unexpected sed behavior in pipes
+**Learning:** `sed 's// /g'` without a prior regex fails (exit code 1) on some systems/versions, and when used in a pipe like `cat | sed | tr`, it can cause the pipe to effectively transmit nothing if the failure happens early or in a specific way, leading to silent data loss.
+**Action:** Always validate `sed` commands in isolation. Prefer strict filtering (like `tr -cd`) over ambiguous replacement when sanitizing data. Avoid unnecessary pipes to prevent masking errors.
