[E2E] Bootstrap: emit deploy manifest JSON

[sadiq1971]

Context

The E2E service discovery layer needs contract addresses and Canton party IDs after bootstrap completes. Currently scripts/setup/docker-bootstrap.sh only injects values via sed into config files — there is no machine-readable output for tests to consume.

Goal

At the end of scripts/setup/docker-bootstrap.sh, write /tmp/e2e-deploy.json with all values that the E2E service discovery layer needs:

{
  "prompt_token":            "<TOKEN_ADDR>",
  "canton_bridge":           "<BRIDGE_ADDR>",
  "prompt_instrument_admin": "<PARTY_ID>",
  "demo_instrument_admin":   "<PARTY_ID>"
}

Mount a named volume e2e-deploy on the bootstrap container so the file is accessible to the service discovery layer.

Files

File	Change
scripts/setup/docker-bootstrap.sh	Append jq -n ... > /tmp/e2e-deploy.json at the very end (before the WAIT_FOREVER block)
docker-compose.yaml	Add e2e-deploy:/tmp volume mount on bootstrap service; declare e2e-deploy in top-level volumes:

Implementation sketch

In docker-bootstrap.sh, after the existing BOOTSTRAP COMPLETE echo block:

# Write deploy manifest for E2E service discovery
cat > /tmp/e2e-deploy.json <<JSON
{
  "prompt_token":            "${TOKEN_ADDR}",
  "canton_bridge":           "${BRIDGE_ADDR}",
  "prompt_instrument_admin": "${PARTY_ID}",
  "demo_instrument_admin":   "${PARTY_ID}"
}
JSON
echo "Deploy manifest written to /tmp/e2e-deploy.json"

In docker-compose.yaml, under the bootstrap service:

volumes:
  - ./contracts/ethereum-wayfinder/broadcast:/app/broadcast:ro
  - config_state:/app/state
  - e2e-deploy:/tmp          # ← add this line

And in the top-level volumes: block:

e2e-deploy: {}

Acceptance Criteria

• After docker compose up --wait, running:

  docker compose exec bootstrap cat /tmp/e2e-deploy.json
  

  returns valid JSON with non-empty prompt_token, canton_bridge, prompt_instrument_admin, demo_instrument_admin.
• The change is additive — existing config sed patching is unchanged.

Dependencies

None — this is the root of the E2E dependency chain.
