+## Process Entrypoints
+
+### Bootstrap Gate (REQUIRED)
+
+**The bootstrap gate is the ONLY allowed entry point for deployment.**
+
+```bash
+# Using Makefile (recommended)
+make runtime-bootstrap-gate
+
+# Or directly using the script
+bash infra/scripts/runtime-bootstrap-gate.sh
+```
+
+This gate:
+1. Runs `init-job bootstrap` (migrate + init-data)
+2. Starts web and worker services
+3. Aborts if bootstrap fails (prevents web/worker startup)
+
+**Deployment without passing the bootstrap gate is PROHIBITED.**
+
+### New Entrypoints (Phase 1-2, 2026-02-24)
+
+**Primary (recommended):** Use Docker Compose orchestration.
+
+```bash
+# Bootstrap gate (required before web/worker)
+docker compose --env-file .env -f infra/docker/docker-compose.yml run --rm init-job bootstrap
+
+# Web
+docker compose --env-file .env -f infra/docker/docker-compose.yml up -d web
+
+# Worker (grouped)
+docker compose --env-file .env -f infra/docker/docker-compose.yml up -d \
+  worker-critical worker-default worker-bulk
+```
+
+**One-shot jobs:**
+```bash
+# Migrate only
+docker compose --env-file .env -f infra/docker/docker-compose.yml run --rm init-job migrate
+
+# Init data only
+docker compose --env-file .env -f infra/docker/docker-compose.yml run --rm init-job init-data
+
+# Full bootstrap (migrate + init-data)
+docker compose --env-file .env -f infra/docker/docker-compose.yml run --rm init-job bootstrap
+```
+
+### One-shot CLI (local development)
+
+```bash
+# Bootstrap (migrate + init-data)
+PYTHONPATH=backend/src uv run python -m core.runtime.cli bootstrap
+
+# Migrate only
+PYTHONPATH=backend/src uv run python -m core.runtime.cli migrate
+
+# Init data only
+PYTHONPATH=backend/src uv run python -m core.runtime.cli init-data
+```
+
 ## Logging
 
 **MUST use project logger for all runtime logging.**
