## 2025-05-20 - Pre-compiling Regex in Loops
**Learning:** `re.findall(pattern, string)` recompiles (or retrieves from cache) the pattern on every call. In high-frequency functions called inside loops (like complexity estimation), this overhead adds up.
**Action:** Always pre-compile regexes (`re.compile`) into module-level or class-level constants if they are used repeatedly, especially in tight loops or recursive functions.

El encabezado usa el literal $(date +%Y-%m-%d), que parece un placeholder de shell y no una fecha real. Para que el log sea estable y legible en el repo, reemplazarlo por una fecha concreta (p. ej. 2026-04-27) o por un texto neutral sin sustitución de comandos.

## $(date +%Y-%m-%d) - O(N*M) nested loops into O(N) pre-computed lookups

**Learning:** Found O(N*M) loop performance bottlenecks in `evolutia/material_extractor.py` and `evolutia/rag/rag_indexer.py`. The nested loops were matching solutions to exercises.
**Action:** Replace the nested loop that pairs exercises with solutions with an O(N) pre-computed dictionary that indexes solutions by `exercise_label`.
