## Internal vs External Edges

- Internal resolved imports (EXTRACTED): 7
- Cross-boundary resolved imports (EXTRACTED): 7

## Connections

- [EXTRACTED] depends_on community 0 <-> 1 (strength 0.9): Extracted import edge crosses communities: beacon3.c imports cJSON.h.
- [EXTRACTED] depends_on community 1 <-> 4 (strength 0.9): Extracted import edge crosses communities: include/beacon_common.c imports include/aes.h.
- [EXTRACTED] depends_on community 1 <-> 5 (strength 0.9): Extracted import edge crosses communities: include/beacon_common.h imports include/config.h.
- [INFERRED] shares_context community 1 <-> 2 (strength 0.5): Inferred shared context (language c and layer utility) with no import path between community 1 (include: cJSON) and community 2 (bof/include).
- [INFERRED] shares_context community 1 <-> 6 (strength 0.5): Inferred shared context (language c) with no import path between community 1 (include: cJSON) and community 6 (include: aes_cfb).
- [INFERRED] shares_context community 1 <-> 7 (strength 0.5): Inferred shared context (layer utility) with no import path between community 1 (include: cJSON) and community 7 (orphans).

## Risks

- [dataflow UNCHECKED_ALLOC] `beacons/v1/beacon.c:66` `report_result` `full_enc`: Result of allocator stored in `full_enc` is never checked against NULL.
- [dataflow UNCHECKED_ALLOC] `beacons/v1/beacon.c:102` `execute_command` `payload`: Result of allocator stored in `payload` is never checked against NULL.
- [dataflow UNCHECKED_ALLOC] `beacons/v2/beacon.c:108` `report_result` `full_enc`: Result of allocator stored in `full_enc` is never checked against NULL.
- [dataflow UNCHECKED_ALLOC] `beacons/v2/beacon.c:144` `execute_command` `payload`: Result of allocator stored in `payload` is never checked against NULL.

- [dataflow UNCHECKED_ALLOC] `beacons/v3/beacon.c:130` `execute_command` `payload`: Result of allocator stored in `payload` is never checked against NULL.
- [dataflow DEAD_STORE] `cJSON.c:1654` `print_array` `output_pointer`: `output_pointer` assigned at line 1654 but never read afterwards.
- [dataflow DEAD_STORE] `cJSON.c:1887` `print_object` `output_pointer`: `output_pointer` assigned at line 1887 but never read afterwards.
- [dataflow UNCHECKED_ALLOC] `include/beacon_common.c:300` `base64_encode` `buf`: Result of allocator stored in `buf` is never checked against NULL.

## Open Questions

- Why do 9 file(s) lack file-level docs (e.g. `beacons/v1/beacon.c`)? What purpose do they serve?
- What would break if the most connected file in include: cJSON changed?
- Should include: cJSON be split, given cohesion 0.57?
