# Unified-mode e2e configuration fixtures

Fixtures for the five `unified-mode-*.feature` files (LCORE-2341/LCORE-2343).
Same layout as the parent directory: `library-mode/` and `server-mode/`
variants differing only in the `llama_stack` block; the harness resolves
`<dir>/<mode>/<file>` via the standard `configure_service` logic.

All profile-based fixtures reference `run.yaml` — the repo-root copy the CI
harness materializes from `tests/e2e/configs/run-<env>.yaml` — so they stay
provider-agnostic across the providers matrix.

| Fixture | Purpose |
|---|---|
| `lightspeed-stack-unified-providers.yaml` | Minimal unified config driven only by top-level `inference.providers` (default baseline, R1/S5). openai-specific — used by `@openai-only` scenarios. |
| `lightspeed-stack-unified-config-only.yaml` | Unified config driven only by `llama_stack.config` (`profile: run.yaml`, R1). |
| `lightspeed-stack-unified-relative-profile.yaml` | Same shape as config-only; exists to pin R8 (relative `profile:` resolves against the config file's directory) as a distinct intent. |
| `lightspeed-stack-unified-absolute-profile.yaml` | `profile:` as a container-absolute path (differs per mode subdir). |
| `lightspeed-stack-unified-native-override-scalar.yaml` | `native_override` replaces an overlapping scalar key (R5). Synthesis-only; never booted. |
| `lightspeed-stack-unified-native-override-list.yaml` | `native_override` replaces an overlapping list wholesale (R5). Synthesis-only; never booted. |
| `lightspeed-stack-invalid-providers-and-legacy.yaml` | INVALID: `inference.providers` + `library_client_config_path` (mutual exclusion, R3). Validation-only. |
| `lightspeed-stack-invalid-config-and-legacy.yaml` | INVALID: `llama_stack.config` + `library_client_config_path` (R3). Validation-only. |
| `lightspeed-stack-invalid-version-legacy-unified-body.yaml` | INVALID: `config_format_version: legacy` on a unified-shaped body (R11, LCORE-2872). Validation-only. |
| `lightspeed-stack-legacy-for-migration.yaml` | Legacy half of "the legacy migration fixture pair"; paired with the repo-root `run.yaml`. Deliberately free of enrichment sections so migrate→synthesize round-trips losslessly (see LCORE-3370). |
| `lightspeed-stack-unified-migrated.yaml` | Generated at test time by the `--migrate-config` step; gitignored and cleaned up after each scenario. |

🔒 Security & Privacy | 🟡 Minor | ⚡ Quick win

Constrain unauthenticated E2E listeners to loopback.

These bootable fixtures disable authentication while Compose publishes port 8080 on all host interfaces. A test worker reachable from the surrounding network could therefore expose the service without authentication. Bind the published mapping to 127.0.0.1:8080:8080 or enable test authentication in the Compose configurations for the listed boot fixtures. The native-override fixtures are synthesis-only and are not included.

Not taking this one, but not because the concern is wrong.

The all-interfaces exposure isn't introduced by these fixtures — docker-compose.yaml already publishes "8080:8080" on main, and the existing e2e fixtures run with authentication disabled too. These unified-mode fixtures follow that established pattern rather than departing from it, so changing the binding here would fix one corner of a repo-wide setup while leaving the rest as-is, inside a PR about behave step definitions.

If the e2e harness should bind published ports to loopback, that's worth doing across docker-compose.yaml and all fixtures at once, as its own change. Happy to file it if you agree.

@max-svistunov, I agree. The unified-mode fixtures do not introduce this exposure. A partial change in this PR would leave the existing E2E harness inconsistent.

Please file a follow-up issue for a repository-wide review of unauthenticated E2E port publishing, including docker-compose.yaml and the related fixture or harness configurations.

Learning: In the Lightspeed Stack E2E environment, `docker-compose.yaml` already publishes port `8080` as `"8080:8080"`, and existing E2E fixtures disable authentication. Unified-mode fixtures follow this established pattern. Any localhost-binding remediation must cover the E2E harness and all relevant fixtures in a dedicated repository-wide change.

Filed as LCORE-3787 — "Bind published E2E ports to loopback (or enable auth on E2E fixtures)".

It covers the whole harness rather than these fixtures: reviewing every published mapping in docker-compose.yaml, moving what can be loopback-bound to 127.0.0.1:<port>:<port>, enabling test auth or documenting rationale for anything that genuinely needs a non-loopback listener, and confirming both the GitHub Actions e2e matrix and Prow still pass afterwards (Prow reaches services via port-forward, so it needs separate verification).

@max-svistunov, thank you. LCORE-3787 has the correct repository-wide scope.

The issue covers the required port-mapping review, exception handling, and CI verification for both GitHub Actions and Prow. This PR can retain the existing fixture pattern until that follow-up change is complete.
