writeReceipt (fail-closed, sha256:null — a subprocess or SDK owns the
wire bytes) before every TS-module network-bearing operation:
- bin/gstack-gbrain-sync.ts: before the gbrain code walk that ships
repo content to the user's gbrain DB (may be remote Postgres). A
refused receipt fails the stage with status refused-egress-receipt.
- bin/gstack-memory-ingest.ts: before the gbrain batch import of
transcript pages. A refused receipt returns a system_error verdict
without spawning the import.
- browse/src/server.ts: before both ngrok.forward call sites (start-up
BROWSE_TUNNEL=1 path and the /tunnel/start endpoint). A receipt
failure lands in the existing catch that tears the tunnel listener
back down and refuses the start.
