/*
|
||||
* service_patterns.c — Classify call edges by library identity in resolved QN.
|
||||
*
|
||||
* Instead of matching callee names (ambiguous: "get", "post", "send"),
|
||||
* we match library identifiers in the RESOLVED qualified name. The QN
|
||||
* contains the full module path, so import aliases are transparent:
|
||||
* r.get("/api") → QN: project.venv.requests.api.get → match "requests" → HTTP_CALLS
|
||||
*
|
||||
* Two-level matching:
|
||||
* 1. Library identifier in QN → determines edge type (HTTP/ASYNC/CONFIG)
|
||||
* 2. Method suffix → determines HTTP method (get→GET, post→POST)
