Server-push channels are long-lived data sources, not request/response fetches. - New `sse` DataSourceKind (schema regenerated); new pushchannels.ts: detectPushChannel matches `new WebSocket(url)` / `new EventSource(url)` by constructor name (allowing a window./self. qualifier — low false-positive set) and resolves the URL through the existing resolveEndpoint. - extractBodyFacts gains a NewExpression pass emitting the data-source node + fetches-from edge, mirroring the fetch path (skipped inside API wrappers). websocket for WebSocket, sse for EventSource; transport in method (WS/SSE). - New fixture c8-push-channels (WebSocket wss:// + SSE /api/.../stream); 4 unit tests. eval 332/0/0/0, determinism 1.000, all metrics 1.000; parser-react 164 tests, schema drift gate green, typecheck + lint clean. socket.io deferred (needs import-aware detection).

Phase 7.3 — Push channels (failure mode C8)
Server-push data arrives over a long-lived connection, not a request/response fetch. This recognizes
new WebSocket(url)andnew EventSource(url)as data sources so a component fed by a live channel shows it in its lineage.Changes
sseDataSourceKind(schema regenerated, drift gate green) — honest for EventSource;websocketstays for WebSocket.pushchannels.ts:detectPushChannelmatches anew WebSocket(...)/new EventSource(...)expression by constructor name (allowing awindow./self.qualifier — a very low false-positive set) and resolves the URL through the existingresolveEndpoint(constant-folded,:param-normalized).extractBodyFactsgains aNewExpressionpass that emits the data-source node +fetches-fromedge, mirroring the fetch path (skipped inside API wrappers).
