Description

Implements LCORE-2343: behave step definitions, fixtures, and gating for the five unified-mode-*.feature files authored spec-first in LCORE-2341 (PR #2020), and unskips them.

Step definitions (tests/e2e/features/steps/unified_mode.py, 16 new patterns — boot/legacy resolve entirely through existing generic steps): validation runs the service CLI (--dump-configuration) as a black-box subprocess against the on-disk active configuration and asserts a non-zero exit; migration runs the real --migrate-config CLI into a scratch directory, asserts the CLI wrote the output 0600 (R10: migrated files may carry lifted secrets), then publishes a deliberate 0644 copy under the fixture name for configure_service to boot (gitignored, cleaned per scenario) — the harness relaxation applies only to that copy, never to the CLI artifact; synthesis runs the config CLI exactly as the server entrypoint does (unified auto-detect → synthesize_to_file, giving the 0600 mode the permissions scenario asserts). All comparisons are YAML-data equality, never bytes; override assertions are self-referential against the fixture's native_override and additionally assert the baseline differed, so replacements cannot pass vacuously. The --synthesized-config-output scenario launches a short-lived local service from the library-mode fixture variant on a rewritten port and polls for the custom output.
Mode-aware startup-log step: in server mode the synthesis evidence is emitted by the llama-stack container (entrypoint + CLI), not the lightspeed-stack container the Gherkin names — the step inspects the container that actually synthesizes, with the rationale documented in the step (agreed deviation; scenario intent is R10 "path is logged at startup").
Fixtures (tests/e2e/configuration/unified-mode/{library-mode,server-mode}/, 20 files + README): every fixture validated against the real Configuration model — bootable ones load in both modes, the three invalid ones fail with exactly the intended errors. Profile-based fixtures consume the CI-materialized ./run.yaml, staying provider-agnostic across the providers matrix.
Legacy-fidelity fix (agreed in planning): LCORE-2342 migrated the standard library baseline to unified mode, silently removing R2's library-mode legacy boot coverage — a dedicated lightspeed-stack-legacy.yaml fixture restores it, with a one-line Given edit in unified-mode-legacy.feature (rationale in a Gherkin comment and the commit message). See Gherkin edits below for the complete list.
Gating: all five features tagged @skip-in-prow (Docker/subprocess dependencies); the two openai-hardcoded boot scenarios tagged @openai-only with a before_scenario skip keyed on E2E_DEFAULT_PROVIDER_OVERRIDE, so the providers matrix (azure/watsonx/bedrock full-list runs) skips them instead of failing.
Harness fix surfaced by these scenarios: restart_container waited on docker health, which can report healthy before uvicorn binds the port (the documented race wait_for_lightspeed_stack_http_ready exists for, previously closed only in proxy steps) — the unified first boots are the slowest restarts in the suite and hit it reliably; the HTTP-ready wait is now wired into every lightspeed-stack restart.
Unskip: @skip removed from the five features. Rebased over the LCORE-3537 e2e rework: the features carry main's @cfg_unified affinity tag (plus @skip-in-prow), so the existing cfg_unified CI shard picks them up on unskip. (Two mid-branch commit messages predate the rework and mention the old @e2e_group_2 sharding; the final state is @cfg_unified.)
Post-rebase fixes (2026-08-27): rebased onto the OGX rename (LCORE-2547: Renamed non-functional LLS occurrences #2516/LCORE-2547: rename internal LlamaStack Python identifiers to Ogx #2547) plus the merged LCORE-2338/3370/3694 work, then corrected three things the rebase exposed. (a) The synthesis-log assertions still matched the pre-rename messages; they had kept passing only through incidental fallback alternatives, so they were asserting something other than the message they name — repointed at Using synthesized OGX config and Wrote synthesized OGX configuration. (b) lightspeed-stack-legacy.yaml still declared BYOK under the pre-LCORE-1426 byok_rag/rag.tool keys and no longer loaded at all under extra="forbid" — migrated to rag.byok.stores / rag.retrieval.tool.sources. (c) The migrate step relaxed the CLI's own artifact to 0644; it now asserts 0600 and relaxes a copy instead (see the step-definitions bullet).

No open dependencies remain: LCORE-2338 (PR #2319), LCORE-3370 (PR #2449), LCORE-3694 (PR #2528) and LCORE-2872 (config_format_version) have all merged, so every scenario now fails/passes for the right reason.

Gherkin edits

LCORE-2343 requires the .feature files be taken as-is, and that any edit be documented with explicit rationale. Four edits were made, none of which weakens a scenario:

@skip → @skip-in-prow (all five files) — the unskip this ticket exists to perform. Prow lacks the Docker Compose services these scenarios drive; every other environment runs them.
@openai-only added to two boot scenarios — the fixtures hardcode an openai provider, so the providers matrix (azure/watsonx/bedrock) skips rather than fails them. Enforced by a before_scenario hook keyed on E2E_DEFAULT_PROVIDER_OVERRIDE.
unified-mode-legacy.feature: Given The service uses the lightspeed-stack.yaml configuration → lightspeed-stack-legacy.yaml. LCORE-2342 migrated the library-mode baseline to unified mode, which silently removed R2's legacy two-file boot coverage; a dedicated legacy-shaped fixture restores it. Rationale is also inline as a Gherkin comment.
unified-mode-migration.feature: two scenarios titled "drives byte-identical Llama Stack behavior" renamed to "boots and serves queries". Neither compares anything byte for byte — they assert readiness 200 and a query 200. The byte-level claim belongs to the round-trip scenario above them, which does compare parsed data. Title-only; no step, tag filter or test_list.txt entry references either title.

Checklist before requesting a review

I have performed a self-review of my code.
PR has passed all pre-merge test jobs.
If it is a core feature, I have added thorough tests.

Testing

Scope of these results. The full behave runs below were executed on 2026-08-04 against a local merge with PR #2317 and PR #2319, docker-compose stacks in both modes, live OpenAI key. The branch has since been rebased onto the LCORE-3537 e2e rework, the OGX rename and the LCORE-1426 RAG refactor. The full suite has not been re-run on the current head — step matching and the unit suite have, and CI covers the rest. Treat items 2 and 3 as the last known full-suite state, not as a claim about 924c044e.

Step-pattern completeness (no stack needed):
uv run behave --dry-run tests/e2e/features/unified-mode-*.feature
Actual, re-run on the current head 924c044e (2026-08-27): 24 scenarios, 200 steps, zero undefined — satisfies the acceptance criterion directly.
Library mode: start the library compose stack, then
E2E_DEPLOYMENT_MODE=library uv run behave tests/e2e/features/unified-mode-*.feature
Actual: 17 scenarios passed, 0 failed, 7 skipped (server-only variants) — includes migrate→synthesize round-trip, the custom --synthesized-config-output service subprocess, and the startup-log check.
Server mode: start the full compose stack, then the same run with E2E_DEPLOYMENT_MODE=server and E2E_LLAMA_HOSTNAME=llama-stack exported (the validation subprocess resolves the fixture's ${env.E2E_LLAMA_HOSTNAME}; CI sets it at job level).
Actual: 17 scenarios passed, 0 failed, 7 skipped (library-only variants) — all validation, migration, and synthesis scenarios green, mode-aware log step verified against the llama-stack container.
uv run make format — clean on the rebased head. Full make verify deferred to CI (local machine constraint); the last full local verify on this branch was clean except the 14 pre-existing mypy errors in tests/unit/utils/test_models_dumper.py.

Merge Risk: 🔵 Low · up to 924c0

This PR enables unified-mode end-to-end coverage for boot, validation, migration, and synthesis. It is mergeable with owner awareness for constraining unauthenticated test listeners, requiring the startup log to include a synthesized path, bounding readiness waits, and removing the YAML formatting issue; these are localized test-environment risks that could expose a test service or weaken failure detection.

Full details: Docstring Coverage

Explanation

Docstring coverage is 96.15% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 26 functions across 3 files. (28 skipped: 28 unsupported.)

Full details: Performance And Algorithmic Complexity

Explanation

PASSED. The pull request introduces no meaningful performance regression under the stated conditions. New polling is bounded: custom-output polling runs for at most 60 seconds, CLI calls have a 120-second timeout, and HTTP readiness uses at most 80 attempts. The fixtures are small, fixed YAML files. The changes add no O(n^2) handler or K8s operation, N+1 API pattern, unbounded cache or watcher, or paginated-list omission. The readiness call activates an existing bounded probe and normally returns on the first successful request.

Full details: Security And Secret Handling

Explanation

PASSED. The PR changes only e2e fixtures, Behave steps, feature tags, and test harness behavior. It adds no API endpoints, Kubernetes Secret manifests, or production authorization paths. Provider credentials use ${env.OPENAI_API_KEY} or api_key_env. The api_key: xyzzy values are established non-secret test sentinels already used in existing examples and tests. New subprocess calls use argument lists without shell evaluation. The new log assertion checks fixed container logs for synthesis-path text and does not print log contents. No plaintext secret logging, injection path, sensitive API response leak, or missing OwnerReference condition was introduced.

Create tests/e2e/configuration/unified-mode/ with library-mode/server-mode variants (same two-subdir layout configure_service resolves), covering the five unified-mode feature files: - unified-providers: minimal unified config driven only by top-level inference.providers over the default baseline (R1/S5); openai-specific. - unified-config-only / unified-relative-profile: profile: run.yaml — the CI-materialized repo-root run.yaml as baseline, provider-agnostic (R1/R8; two files because the features pin the intents separately). - unified-absolute-profile: container-absolute profile paths, differing per mode subdir (/app-root vs /opt/app-root mounts). - unified-native-override-{scalar,list}: R5 replacement semantics fixtures, synthesis-only, never booted. - invalid-{providers,config}-and-legacy: mutual-exclusion validation fixtures (R3); invalid-version-legacy-unified-body: R11 marker mismatch (needs LCORE-2872's cross-validation to fail for the right reason). - legacy-for-migration: legacy half of the migration fixture pair, kept free of enrichment sections so migrate-then-synthesize round-trips losslessly (LCORE-3370). Every fixture is validated against the real Configuration model: bootable ones load, invalid ones fail with the intended error. The test-generated lightspeed-stack-unified-migrated.yaml is gitignored, and the directory README documents each fixture's purpose.

…d fixture LCORE-2342 migrated the standard library-mode baseline to unified mode (config.profile: run.yaml), which silently changed what unified-mode-legacy.feature's library scenario exercises: it now boots the unified baseline, not the deprecated two-file path, so R2's library-mode legacy coverage was gone. Add lightspeed-stack-legacy.yaml — identical to the baseline except its llama_stack block uses the true legacy shape (use_as_library_client + library_client_config_path: run.yaml, no synthesis input) — and point the library scenario's Given at it. This is the one deliberate Gherkin edit in LCORE-2343, agreed with Maxim in planning; the server-mode scenario is untouched since container-side enrichment there is genuinely legacy.

Add tests/e2e/features/steps/unified_mode.py — the 16 step patterns the validation, migration, and synthesis features need (boot and legacy resolve entirely through existing generic steps). Per the planning decisions: - All artifact steps operate on the ON-DISK configuration (the repo-root lightspeed-stack.yaml copy configure_service applied), never the live service. - Validation runs the service CLI (--dump-configuration) as a black-box subprocess from the repo root and asserts a non-zero exit, so the error-contains assertions can never pass against a healthy load. - Migration runs the real --migrate-config CLI; the output lands in the active mode subdir under the gitignored name later Gherkin references, and is cleaned up per scenario. - Synthesis runs the config CLI exactly as the server entrypoint does (unified auto-detection -> synthesize_to_file, giving the 0600 mode the permissions scenario asserts). Round-trip and override assertions parse YAML and compare data, never bytes; override assertions are self-referential against the fixture's native_override and additionally assert the baseline differed, so replacements can't pass vacuously. - The --synthesized-config-output scenario launches a short-lived local service from the library-mode fixture variant on a rewritten port and polls for the custom output file (the flag is library-mode-only by design; running containers cannot be restarted with new CLI args). - The startup-log step is mode-aware: in server mode the synthesis evidence is emitted by the llama-stack container (entrypoint + CLI), not the lightspeed-stack container the Gherkin names — asserted against the synthesizing container with the rationale documented in the step. behave --dry-run over the five features: 24 scenarios, 200 steps, zero undefined.

Tag all five unified-mode features @skip-in-prow: the new steps rely on Docker containers and local subprocesses, neither of which exists in the Prow environment (existing convention, handled in before_scenario). Add an @openai-only tag on the two inference.providers boot scenarios and a matching before_scenario skip keyed on E2E_DEFAULT_PROVIDER_OVERRIDE: the providers workflow runs the full unsharded test list against azure/watsonx/bedrock matrices, and the unified-providers fixture hardcodes an openai provider that cannot serve those models' queries. Profile-based fixtures stay provider-agnostic (they consume the CI-materialized run.yaml) and need no gating.

@Skip

Remove the @Skip placeholder tag from the five unified-mode features: the step definitions and fixtures they need now exist. The features keep @skip-in-prow (Docker/subprocess dependencies) and stay in test_list.txt under @e2e_group_2, so CI shards pick them up via 'not @Skip and @e2e_group_2' and local runs via --tags=-skip.

restart_container waits on docker health, but docker can report healthy before uvicorn binds the published port — the exact race wait_for_lightspeed_stack_http_ready documents and was, until now, only closed in the proxy steps. The unified-mode boot scenarios are the slowest restarts in the suite (first unified/default-baseline boots) and hit that window reliably: the restart step passed while the following readiness GET got connection-refused. Call the existing HTTP-ready wait from restart_container for the lightspeed-stack container, closing the race for every restarting scenario; when the port is already accepting, the first poll returns immediately.

--migrate-config writes its output 0600 (R10: migrated files may carry lifted secrets), but the boot scenarios copy that file to the repo root for the container to consume, and the container user cannot read a host-owned 0600 file — the migrated-config boot scenario died on config read. Relax the harness copy to 0644 after a successful migration; the fixture pair is env-reference-only by design, so no secret can leak.

The library-mode legacy fixture declared its BYOK store under a top-level byok_rag key with rag_type, and its tool retrieval sources under rag.tool. LCORE-1426 (commit c1de7f9) refactored RAG configuration into a single rag section: stores moved to rag.byok.stores, retrieval sources to rag.retrieval.tool.sources, and RagStore.rag_type was replaced by RagStore.backend, whose validator accepts only the values in SUPPORTED_RAG_BACKENDS (faiss, pgvector). Configuration models inherit ConfigurationBase with extra=forbid, so after rebasing onto main this fixture raised two extra_forbidden validation errors (rag.tool and byok_rag) and the config could not be loaded at all, failing every legacy library-mode scenario that consumes it. Move the store under rag.byok.stores, replace rag_type: inline::faiss with backend: faiss, and nest the retrieval source list under rag.retrieval.tool.sources. score_multiplier, db_path, embedding_model, embedding_dimension and vector_db_id are unchanged and remain valid RagStore fields. The source id stays e2e-test-docs so the validate_retrieval_sources model validator still resolves it against the declared store.

The migration step ran --migrate-config straight into the fixture directory and then chmod'ed that file to 0644 so the container user could read the copy configure_service places at the repo root. That widened the CLI's own output, which is the artifact R10 governs: migrated configurations may carry secrets lifted out of the legacy run.yaml, and the CLI deliberately writes them owner-only (it logs "mode 0600" when it does). The harness therefore destroyed the property it exists to protect, and no scenario noticed because the 0600 assertion only covers the synthesized run.yaml, not the migrated config. A fixture that ever carries a real secret would have had it published world-readable with nothing failing. Migrate into a scratch directory instead, assert the CLI wrote 0600 there, and publish a separate deliberate 0644 copy under the name the Gherkin steps reference for configure_service to boot. The mode relaxation now applies to a copy that exists only for the harness, the CLI artifact keeps its mode, and the R10 guarantee gains the direct assertion it previously lacked.

…sages The startup-logging step matched "Using synthesized Llama Stack config" in library mode and "Wrote synthesized Llama Stack configuration" in server mode. The OGX rename (PRs lightspeed-core#2516 and lightspeed-core#2547) replaced both: client.py now logs "Using synthesized OGX config at %s" and llama_stack_configuration.py logs "Wrote synthesized OGX configuration to %s (mode 0600)". Neither scenario started failing, which is the reason to fix it now rather than after a real breakage. Library mode kept passing only because the sibling alternative "synthesized.*run\.yaml" incidentally matches the OGX line, the synthesized file being named run.yaml; server mode kept passing on the entrypoint's own "Using generated config:" and "mode auto-detected" echoes. Both scenarios were therefore asserting something other than the message they name, and would have gone silently unprotected the moment the output filename or the entrypoint echoes changed. Point the patterns at the current messages and record in the docstring where each one is emitted, so the next rename has an obvious place to look.

Both scenarios were titled "drives byte-identical Llama Stack behavior", but neither compares anything byte for byte: they boot the migrated configuration, assert readiness returns 200, and assert a query returns 200. The byte-level claim belongs to "migrate then synthesize round-trips to the original run.yaml" earlier in the same file, which does compare parsed data. Feature files are read as specification, so a title that overstates its scenario misleads anyone auditing what unified-mode migration is actually covered by. Rename both to "boots and serves queries", which is what the steps verify. No step definition, CI tag filter or test_list entry references either title, so this is a documentation-only change.

🔒 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.

Source: Coding guidelines

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.

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.

YAMLlint reports "too many blank lines (1 > 0)" at the end of lightspeed-stack-legacy.yaml, which fails the configured formatting check. Strip the trailing newline so the file ends immediately after its last mapping entry.

…message The startup-log step accepted "mode auto-detected" in server mode and a bare "Using synthesized OGX config" in library mode, neither of which carries a path. scripts/llama-stack-entrypoint.sh echoes "(mode auto-detected)" unconditionally and *before* it runs the config CLI, so a scenario asserting R10 ("the synthesized path is logged at startup") passed even when synthesis had failed outright — the precise failure the assertion exists to catch. Require a non-empty path in every alternative: "Using synthesized OGX config at <path>", "Wrote synthesized OGX configuration to <path>", and the entrypoint's "Using generated config: <path>", which unlike the auto-detect echo is only emitted after a successful generation. Verified against the three real messages, and that the pre-synthesis echo is now rejected.

…dline wait_for_lightspeed_stack_http_ready counted attempts rather than tracking wall-clock time, so its real ceiling was the per-request timeout plus the sleeps: 80 * 5s + 79 * 1.5s = 518.5s. The AssertionError reported only the backoff total, "~120s", understating the worst case by a factor of four. That gap matters more since this branch wires the wait into every lightspeed-stack restart rather than only the proxy steps: a container that never binds its port could stall a run for over eight minutes per restart, across the eight call sites of restart_container, while the failure text claimed two. Replace the attempt counter with one monotonic deadline covering both the requests and the sleeps, clamp each request timeout to the time remaining, skip a final sleep that would overrun the budget, and report the attempts and elapsed time actually spent. The default budget is 120s, which is what the old message always claimed the bound was.
