| ## Deployment Readiness |
| |
| ### Development |
| ```bash |
| cd seb/runtime |
| make build |
| make test |
| make console |
| ``` |
| |
| ### Staging |
| ```bash |
| make release |
| # seb_release.tar.gz created |
| tar xzf seb_release.tar.gz |
| ./seb_release/bin/seb_release start |
| ``` |
| |
| ### Production |
| ```bash |
| make verify-build |
| # All checks pass |
| # Tag: g3-release-v1.0.0 |
| ``` |
| |
| --- |
| |
| ## Known Limitations |
| |
| ### NIF Stubs |
| - `seb_kernel_nif` contains placeholder NIF functions |
| - Real implementation requires C code linking to Ada kernel |
| - Stubs are marked with `%% TODO: Replace with actual NIF call` |
| - Full integration testing requires compiled Ada kernel |
| |
| ### Datalog Engine |
| - `seb_datalog_bridge` assumes Souffle binary available |
| - Port driver supports async queries |
| - Production deployment requires Souffle setup |
| |
| ### Cluster Mode |
| - Distributed mode configured but not tested at 3-node scale |
| - Requires proper networking setup |
| - Cookie management needed for production |
| |

| |
| ## Next Steps (G4 Gate - ADAPTERS) |
| |
| Upon G3 approval: |
| |
| 1. Implement execution adapters |
| - seb_holyc_adapter.erl |
| - seb_shell_adapter.erl |
| - seb_browser_adapter.erl |
| - seb_chain_adapter.erl |
| - seb_financial_adapter.erl |
| |
| 2. Implement WORM sealing integration |
| - seb_worm_sealer.erl |
| - Blake3 + Ed25519 seal generation |
| - Evidence chain commitment |
| |
| 3. End-to-end testing |
| - kernel → runtime → adapters flow |
| - Full event lifecycle |
| - Failure scenarios |
