Definition

This community groups 6 file(s) rooted at include with dominant language c (cohesion 0.56). Central symbols: DOC, FREEDOM_IMPORT_MAP_H, FREEDOM_PREFETCH_H, IM_MAX_DEPTH, IM_MAX_ENTRIES, IM_MAX_SCOPES, IM_MAX_TEXT, IM_URL_MAX. Core file: src/prefetch.c (30 symbols). Documented purpose: Tests for prefetch (Hito 29): pure lookahead scanner + parallel download pool..

Internal vs External Edges

• Internal resolved imports (EXTRACTED): 5
• Cross-boundary resolved imports (EXTRACTED): 4

Connections

• [EXTRACTED] depends_on community 1 <-> 10 (strength 0.9): Extracted import edge crosses communities: gui/browser_ui.c imports include/prefetch.h.

Risks

• No scoped security, taint, cycle, or layer risks.

Open Questions

• Why do 5 file(s) lack file-level docs (e.g. include/import_map.h)? What purpose do they serve?
• What would break if the most connected file in include: prefetch changed?
• Should include: prefetch be split, given cohesion 0.56?
