Subject: [PATCH] =?UTF-8?q?=E2=9A=A1=20Bolt:=20Optimize=20file=20content?=
 =?UTF-8?q?=20extraction=20pipeline?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

💡 What: Replaced the inefficient and buggy `cat | sed | tr` pipeline with direct input redirection `tr < file`.
🎯 Why:
  - Performance: Reduces process forks from 3 to 1 per file.
  - Bug Fix: The `sed 's// /g'` command was invalid (empty regex), causing exit code 1 and potentially empty output on some systems.
📊 Impact:
  - ~66% reduction in process creation overhead during content extraction.
  - Fixes silent failure where file content could be lost.
🔬 Measurement: Verified by extracting content from a test file; previously failed (empty output), now succeeds.

+## 2025-12-22 - [Buggy sed pipeline]
+**Learning:** `sed 's// /g'` (empty regex) causes exit code 1 on some platforms and silent data loss in pipes.
+**Action:** Always verify `sed` syntax and prefer `tr` for simple character filtering to avoid process overhead and portability issues.
