WalkthroughUnified mode now derives durable Llama Stack conversation storage from PostgreSQL or SQLite conversation-cache settings. It adds persistence diagnostics, deployment examples, documentation, and unit and end-to-end coverage. ChangesUnified conversation persistence
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This change enables conversations to survive restarts, but the shipped PostgreSQL example can send credentials and conversation data without TLS, and the restart test does not verify that conversations can actually be continued afterward. Documentation and persistence warnings also have bounded gaps that should be addressed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@docs/user_doc/deployment_guide.md`:
- Around line 165-169: Replace the undefined term “Dumb migration” in the
native_override precedence paragraph with “A direct migration,” while preserving
the existing explanation of run.yaml lifting, backend enrichment, warning
behavior, and restart implications.
In `@examples/lightspeed-stack-unified-conversation-persistence-pg.yaml`:
- Around line 27-45: Update the ssl_mode setting in both the database and
conversation_cache PostgreSQL configurations to require encrypted connections by
default, using require or a stronger accepted mode; leave operators able to
relax it explicitly for local testing.
In `@src/llama_stack_configuration.py`:
- Around line 38-47: Move CONVERSATIONS_BACKEND_NAME and
DEFAULT_CONVERSATIONS_TABLE_NAME from llama_stack_configuration.py into the
central constants.py module, preserving their values, descriptive comments, and
Final[str] annotations; update imports and references accordingly. Leave the
module-private _DURABLE_CACHE_TYPES and _ENV_REF_RE in place.
- Around line 1223-1228: The SQLite ephemeral-path check in the db_type ==
"sqlite" branch must also recognize /var/tmp paths, ./tmp paths, and the bare
/tmp path while preserving the existing default database-path detection. Update
the path-matching condition near constants.DEFAULT_SQLITE_DATABASE_PATH without
changing other database types.
Apply the same fix in `@tests/unit/test_llama_stack_conversation_persistence.py`
around lines 279 - 321: Add coverage for the ephemeral path variants and
existing path branches.
In `@tests/e2e/features/unified-mode-conversation-persistence.feature`:
- Around line 22-28: Add an assertion after the second request in the
unified-mode persistence scenario to verify its response contains the single
word established earlier, rather than checking only status 200. Use the existing
response-body assertion step and preserve the same conversation_id flow across
the restart.
In `@tests/e2e/test_list.txt`:
- Around line 42-43: Remove the duplicate features/skills.feature entry from the
test list, keeping the existing earlier entry and the
features/unified-mode-conversation-persistence.feature entry unchanged.

Learning: In lightspeed-stack (src/utils/conversation_compaction.py), `CompactionResult.summarized` (renamed to `compacted` in PR `#1796` for clarity) is set to `True` whenever a conversation is being served in explicit-input/omit-conversation mode — i.e., any time there is at least one existing summary marker or cache entry so `conversation` is omitted from the Llama Stack request. It is NOT limited to requests where a fresh summary was generated in the current call. When `compacted` is True, `original_input` is always populated, and `store_compacted_turn` must be called to persist the completed turn. This invariant holds for both the "reuse cached/marker summary" path and the "new summarization" path.

Timestamp: 2026-04-13T13:39:59.316Z
Learning: In lightspeed-stack e2e tests (tests/e2e/features/), `context.feature_config` is intentionally set inside Background/step functions (scenario-scoped Behave layer). The `after_scenario` restore logic in `environment.py` only restores config when `context.scenario_lightspeed_override_active` is True, which is only set by `configure_service` when an actual config switch occurs. The module-level `_active_lightspeed_stack_config_basename` in `tests/e2e/features/steps/common.py` prevents re-applying the same config in subsequent scenarios (making `scenario_lightspeed_override_active` stay False). This means the ephemeral nature of step-set context attributes is intentional — the design ensures config restore happens exactly once per actual switch, not redundantly on every scenario.

Timestamp: 2026-05-20T08:09:36.724Z
Learning: In the lightspeed-stack repo, the synthesized `run.yaml` file handling in `src/client.py` (`_synthesize_library_config`) uses a fixed `/tmp` path intentionally in the PoC (PR `#1580`). The durable production requirements are tracked in spec doc R10 (docs/design/llama-stack-config-merge/llama-stack-config-merge.md): persistent known path overwritten each boot, file mode 0600 set via explicit create flag (not umask), and a `--synthesized-config-output` CLI flag for debugging. The PoC code is scheduled for removal pre-merge; the implementation JIRA "Unified llama_stack.config schema + synthesizer" inherits R10's requirements.

Timestamp: 2026-06-24T10:14:57.315Z
Learning: In `src/data/default_run.yaml` (lightspeed-core/lightspeed-stack), the `provider_shield_id: openai/gpt-4o-mini` under the `llama-guard` shield is **intentionally a placeholder**, not a real Llama Guard model. This default baseline is designed for zero-dependency boot using only an `OPENAI_API_KEY`; pinning a real guard model (e.g., `meta-llama/Llama-Guard-3-8B`, ~16 GB) would break that. A comment in the file explicitly states it does not perform real safety gating. Real Llama Guard configuration happens per deployment via the high-level schema or `native_override`, and E2E safety gating is covered by LCORE-2341/LCORE-2343. Do not flag this file's shield entry for using a chat model ID.

Timestamp: 2026-05-20T08:09:30.641Z
Learning: In Llama-stack config YAMLs, when defining a Llama Guard safety shield entry, set `provider_shield_id` to the *guard model identifier* (e.g., `meta-llama/Llama-Guard-3-8B`). Do not use a chat/generative model id (e.g., `openai/gpt-4o-mini`): a chat-model id (or `native_override`) indicates only an override landed and does **not** mean the safety shield is actually gating queries. Ensure any E2E coverage for the related implementation (JIRA/E2E tests) exercises a real Llama Guard model to verify that the shield is effective.

Learning: In the Python codebase, requests.py should use OpenAIResponseInputTool as Tool while responses.py uses OpenAIResponseTool as Tool. This difference is intentional due to differing schemas for input vs output tools in llama-stack-api. Apply this distinction consistently to other models under src/models (e.g., ensure request-related tools use the InputTool variant and response-related tools use the ResponseTool variant). If adding new tools, choose the corresponding InputTool or Tool class based on whether the tool represents input or output, and document the rationale in code comments.

Learning: In `src/utils/conversation_compaction.py` (lightspeed-stack), `compaction.enabled: false` is intentionally a full off-switch and a zero-overhead no-op. It does **not** attempt to honor existing summary markers or cached summaries when disabled, because doing so would require fetching conversation items on every disabled request, breaking the "when off, behaves exactly as before" contract. Disabling compaction mid-conversation on an already-compacted conversation is an explicitly unsupported transition; the limitation is documented in the `apply_compaction` code comment and in the spec doc's Configuration section + Changelog.

Learning: In `src/utils/conversation_compaction.py` (lightspeed-stack), `CompactionResult.compacted` (previously named `summarized`) is `True` whenever the response is served in explicit-input mode — i.e., whenever the `conversation` parameter is omitted from the Llama Stack Responses API call. This covers both cases: fresh summarization AND reuse of an existing summary marker or cache entry. It is always set together with `omit_conversation=True` and a populated `original_input`. Do not flag this field as only covering fresh summarization; it correctly gates the post-stream `append_turn_to_conversation` call in `generate_response` via the `compacted` parameter.

Learning: In `src/llama_stack_configuration.py`, the `apply_high_level_inference` function currently emits `provider_id: p_type` (underscore form, e.g. `sentence_transformers`) directly from the high-level type key, which collides with Llama Stack's hyphenated provider IDs (e.g. `sentence-transformers`). This is a known PoC divergence documented in the spike doc ("Findings discovered during PoC") and tracked in the implementation JIRA "Unified llama_stack.config schema + synthesizer". Decision S5 mandates that each backend-specific synthesizer translates LCORE's canonical type Literal vocabulary to the target backend's expected shape (hyphenated provider_id for Llama Stack; model-string prefixes for Pydantic AI). The PoC code will be removed before merge; the fix belongs in the implementation ticket.

Timestamp: 2026-05-20T08:09:30.641Z
Learning: In Llama-stack config YAMLs, when defining a Llama Guard safety shield entry, set `provider_shield_id` to the *guard model identifier* (e.g., `meta-llama/Llama-Guard-3-8B`). Do not use a chat/generative model id (e.g., `openai/gpt-4o-mini`): a chat-model id (or `native_override`) indicates only an override landed and does **not** mean the safety shield is actually gating queries. Ensure any E2E coverage for the related implementation (JIRA/E2E tests) exercises a real Llama Guard model to verify that the shield is effective.

29-33: 🩺 Stability & AvailabilityVerify the SQLite parent directory and permissions.
Both
db_pathvalues target a new file under/opt/app-root/src. The comment states that LCORE does not create the parent. If the image or local E2E runner does not provide that directory with write permission for the service UID, startup fails before the persistence scenario runs. Confirm the image and runner contract, or use a guaranteed writable mounted directory.

Scope the durability claim to local Docker execution.
In local library mode, /opt/app-root/src/conversation-persistence.db is not volume-mounted. docker restart preserves it only while the same container exists. Replace “not ephemeral” with “survives restart of the same container only.” If container-replacement durability is required, add a persistent volume and replacement coverage.

🩺 Stability & Availability | 🔵 Trivial
Verify the durable conversation store has a capacity policy.
This configuration shows no retention, size, or eviction limit. If the backend does not enforce one elsewhere, the shared SQLite file can grow until the container filesystem is full. Conversation and LCORE writes can then fail. Verify the backend policy and add retention, capacity monitoring, or persistent-volume sizing.
As per coding guidelines: flag unbounded growth in caches, watchers, or buffers when eviction or limits are missing.
