From 7a59380c86516bd8ea6c38a89abb91dd7ec93b4d Mon Sep 17 00:00:00 2001 From: albert Date: Fri, 25 Sep 2026 12:22:22 +0200 Subject: [PATCH 01/32] feat(llm): wire the LLM interpreter and Langfuse tracing into the runtime The LLM layer was implemented and tested but never wired: get_twilio_service() built the orchestrator without an interpreter, so every live WhatsApp message was answered by the deterministic parser, and no TracerProvider was ever installed so nothing reached Langfuse. - Settings now declares the LLM and tracing configuration (llm_provider, model, temperature, tokens, timeout, confidence threshold, prices, provider credentials, Langfuse keys) and derives llm_enabled, traces_endpoint, tracing_enabled and traces_auth_header. It stays the only reader of the environment; the legacy os.getenv helper is gone. - New app/agent/factory.py builds the Strands model per provider (openai default, anthropic, bedrock; OpenAI-compatible gateways via OPENAI_BASE_URL) and build_interpreter() fails closed: disabled provider, missing credential or missing SDK returns None plus one llm_disabled warning, so a rescue is never blocked by LLM configuration. - configure_tracing() installs an idempotent OTLP/HTTP exporter to Langfuse Cloud with Basic auth and injectable exporter/provider for hermetic tests; the FastAPI lifespan configures it and flushes on shutdown. - get_twilio_service() injects the interpreter and logs the active provider; the eval runner uses the same factory, so evals and production resolve the provider identically. - Adds openai and the opentelemetry api/sdk/otlp-http dependencies. --- backend/.env.example | 38 ++-- backend/app/agent/factory.py | 172 ++++++++++++++++ backend/app/api/webhooks_twilio.py | 8 + backend/app/core/config.py | 56 +++++- backend/app/main.py | 4 + backend/app/observability/tracing.py | 83 +++++++- backend/pyproject.toml | 4 + .../tests/unit/api/test_webhooks_twilio.py | 40 ++++ backend/tests/unit/test_agent_factory.py | 162 +++++++++++++++ backend/tests/unit/test_config.py | 85 ++++++++ backend/tests/unit/test_observability.py | 131 ++++++++++++- backend/uv.lock | 185 ++++++++++++++++++ evals/runner.py | 68 +++---- 13 files changed, 970 insertions(+), 66 deletions(-) create mode 100644 backend/app/agent/factory.py create mode 100644 backend/tests/unit/test_agent_factory.py diff --git a/backend/.env.example b/backend/.env.example index 54c3f3d..f9d34ae 100644 --- a/backend/.env.example +++ b/backend/.env.example @@ -9,17 +9,23 @@ JWT_SECRET=dev-only-secret DATABASE_URL=postgresql+asyncpg://shift_rescue:shift_rescue@localhost:5433/shift_rescue REDIS_URL=redis://localhost:6379/0 -# --- LLM (spec §7.2) --------------------------------------------------------- -LLM_PROVIDER=anthropic # anthropic | bedrock | nan -ANTHROPIC_API_KEY= -LLM_MODEL_INTERPRETER=claude-haiku-4-5-20251001 -LLM_MODEL_COMPOSER=claude-sonnet-5 -LLM_MODEL_SUMMARIZER=claude-sonnet-5 -# Optional per-piece provider override (send only the interpreter to NaN): -# LLM_PROVIDER_INTERPRETER=nan -# NAN_API_KEY= -# NAN_BASE_URL=https://api.nan.builders/v1 -# LLM_MODEL_INTERPRETER_NAN=nan/deepseek-v4-flash +# --- LLM (spec §6, ADR-004) -------------------------------------------------- +# Fail-closed: provider "none", a missing key or a missing provider SDK makes +# the API answer with the deterministic parser and log `llm_disabled` — it +# never blocks a rescue.

From 1d3890686742856cfdce2efc301761265549abdd Mon Sep 17 00:00:00 2001 From: albert Date: Fri, 25 Sep 2026 13:31:13 +0200 Subject: [PATCH 09/32] fix(evals): make the accuracy gate fail closed and close the thresholds with prompt v2 The first real-model run exposed three defects, and the most serious one was the gate itself. - check_thresholds() compared hardcoded '..._min' keys against a report that stores the metrics without the suffix, so every lookup returned None, every comparison was skipped and the runner printed 'Thresholds met.' while accuracy was 0.86 against a 0.92 minimum. evals/thresholds.yaml was never read at all. Thresholds now live in app/evals/thresholds.py, read the YAML (one source of truth, min and max directions) and fail closed: an unmapped key, an unknown metric or a non-numeric value is a violation, never a silent pass. - _build_prompt forwarded rescue_id, pending_offers and shifts_48h but dropped pending_confirmation, so a bare '1' had no way to be read as ABSENCE_CONFIRM. It now renders that key and any remaining non-empty context key, with a credential-name filter so a secret can never reach a prompt. - New interpreter_v2 prompt with an explicit procedure keyed on what is pending, numeric replies meaning yes/no only when something is pending, a broader health rule and examples for the confusions v1 exposed. The active version is named once and recorded on every interpretation. Measured with the real provider on the 150-sample golden set: v1: 0.86 accuracy / 0.9167 health / 0.95 times (2 violations, gate silent) v2: 0.9333 accuracy / 1.0 health / 0.85 times (thresholds met, honestly) The 10 remaining failures are analysed in odd/tasks/interpreter-quality.md; six of them need the orchestrator to pass an 'already accepted' marker because the context the harness supplies is identical to cases labelled OFFER_DECLINE. 308 tests pass, ruff and mypy clean.

One row per LLM interpretation now records intent, confidence, the structured fields, model, prompt version, tokens, latency and cost. The parser path writes nothing (a degraded decision is not an LLM decision), a duplicate provider message writes no second row, and a persistence failure is logged without breaking the rescue. _persist_inbound now returns the message id. - OFFER_WITHDRAW was not inferable: the six withdrawal golden rows carried the same context as the decline rows, so the state that makes them withdrawals is now sent as accepted_offers instead of being guessed from the words 'al final'. The fixture gained that key for those rows only, and no label changed. - interpreter_v4 fixes the prompt's own example: every version since v1 claimed 'hasta mediodía puedo' fills proposed_start 07:00 as well, while the labels expect start=null; the model followed the example and lost 5 of 20 extractions. v4 states the rule the data encodes (one boundary fills one field). Measured with the real provider on 150 golden samples: v2 0.9333 / 1.0 / 0.85 v3 0.9867 / 1.0 / 0.75 (times violated) v4 0.9933 / 1.0 / 1.0 one failure left: 'cancele el caso de todos' Also fixes the CI-only test failure: build_runtime(settings) ignored its own settings for the database and fell back to the ambient .env, so the test connected to a developer's local Postgres and failed on a clean runner. It now passes the URL explicitly and the test uses a temp-file database; verified with the Linux CI image. 317 tests pass, ruff and mypy clean. --- backend/app/agent/interpreter.py | 8 +- backend/app/agent/prompts/interpreter_v3.md | 124 +++++++++ backend/app/agent/prompts/interpreter_v4.md | 137 ++++++++++ backend/app/runtime.py | 6 +- backend/app/services/orchestrator.py | 83 ++++++- backend/tests/unit/agent/test_interpreter.py | 23 +- .../unit/services/test_interpreter_wiring.py | 235 +++++++++++++++++- backend/tests/unit/test_runtime.py | 29 ++- docs/eval-report.md | 44 +++- evals/golden/interpreter_golden.jsonl | 22 +- odd/tasks/interpretation-persistence.md | 73 +++++- 11 files changed, 752 insertions(+), 32 deletions(-) create mode 100644 backend/app/agent/prompts/interpreter_v3.md create mode 100644 backend/app/agent/prompts/interpreter_v4.md diff --git a/backend/app/agent/interpreter.py b/backend/app/agent/interpreter.py index 22b9acd..3f3654e 100644 --- a/backend/app/agent/interpreter.py +++ b/backend/app/agent/interpreter.py @@ -12,7 +12,7 @@ from app.agent.schemas import Interpretation from app.ports import LLMClient -PROMPT_VERSION = "interpreter_v2" +PROMPT_VERSION = "interpreter_v4" FALLBACK = Interpretation(intent="UNCLEAR", confidence=0.0) @@ -55,3 +55,9 @@ async def interpret(self, message_body: str, context: dict[str, Any]) -> Interpr raise ProviderUnavailableError(str(error)) from error return FALLBACK + + @property + def last_usage(self) -> dict[str, Any] | None: + """Usage dict of the wrapped client's last call, or None if unreported.""" + usage = getattr(self._llm, "last_usage", None) + return usage if isinstance(usage, dict) else None diff --git a/backend/app/agent/prompts/interpreter_v3.md b/backend/app/agent/prompts/interpreter_v3.md new file mode 100644 index 0000000..ba7c676 --- /dev/null +++ b/backend/app/agent/prompts/interpreter_v3.md @@ -0,0 +1,124 @@ +# interpreter_v3 — system block + +Eres el asistente de turnos de un grupo de restauración.

From a6a4678068d8d6518e7ac859ba8094d4ac21e286 Mon Sep 17 00:00:00 2001 From: albert Date: Fri, 25 Sep 2026 14:06:11 +0200 Subject: [PATCH 12/32] fix(test): stop the worker runtime test from using the ambient database The test failed in CI and passed locally: build_runtime(settings) ignored the settings it was given for the database and fell back to the ambient .env, so the test connected to the developer's local Postgres on 5433 and found nothing to connect to on a clean runner (OSError, 111). The runtime now passes settings.database_url to the engine factory, and the test builds a temp-file SQLite database with the schema, so it is hermetic on any machine.

From 6f417c86c17323647295466802abe19621e57ab6 Mon Sep 17 00:00:00 2001 From: albert Date: Fri, 25 Sep 2026 15:24:34 +0200 Subject: [PATCH 14/32] feat(web): connect the dashboard to the live API The dashboard was a complete UI rendering mock data with no HTTP client. It now authenticates against the real API and reads the real database, using the seam that already existed (DashboardDataSource + hooks) instead of rewriting screens. - Session client (localStorage), an HTTP client that attaches the bearer token and turns failures into a typed ApiError/NetworkError, and a 401 path that clears the session and returns to the login screen. - ApiDashboardDataSource: shifts, active rescues, rescue detail, approvals (enqueue + invalidate, since decisions are applied by the worker), conversations and messages, interpretations, metrics and settings. The location id is resolved from GET /api/locations instead of the hardcoded literal that never matched the seeded database. - Login screen and RequireAuth guard, with the demo credentials shown for the reviewer, distinct messages for wrong credentials and for an offline API, the signed-in manager in the header with a logout action, and deep links preserved across login. - getDataSource() keeps the mock available behind VITE_USE_MOCK (offline demo and hermetic tests). The Evals screen still reads mock data and now says so in the UI, because /api/evals/runs* was deliberately deferred. - Dev proxy /api -> localhost:8000 so development needs no CORS, documented environment variables, and runbook instructions for logging in. - Fixes a real defect found on the way: the settings form seeded its draft once, so live values arriving later could be overwritten by a save with stale defaults. Verified: 119 frontend tests, build, oxlint and tsc clean; the SPA serves and the dev proxy reaches the API (401 without a token, as expected); CORS accepts the configured dashboard origin and rejects others. --- docs/runbook.md | 22 + frontend/.env.example | 7 + frontend/src/App.test.tsx | 44 +- frontend/src/App.tsx | 32 +- frontend/src/components/AppHeader.test.tsx | 21 + frontend/src/components/AppHeader.tsx | 23 + frontend/src/components/RequireAuth.test.tsx | 50 ++ frontend/src/components/RequireAuth.tsx | 38 ++ frontend/src/screens/EvalsScreen.tsx | 5 + frontend/src/screens/LoginScreen.test.tsx | 85 +++ frontend/src/screens/LoginScreen.tsx | 106 ++++ frontend/src/screens/SettingsScreen.test.tsx | 65 +++ frontend/src/screens/SettingsScreen.tsx | 21 +- frontend/src/services/__tests__/api.test.ts | 519 ++++++++++++++++++ .../src/services/__tests__/apiClient.test.ts | 130 +++++ frontend/src/services/api.ts | 254 +++++++++ frontend/src/services/apiClient.ts | 93 ++++ frontend/src/services/auth.ts | 73 +++ frontend/src/services/dashboard.ts | 43 +- frontend/src/services/dataSource.ts | 21 + frontend/src/services/hooks.ts | 13 +- frontend/vite.config.ts | 15 + odd/tasks/dashboard-api.md | 84 +++ 23 files changed, 1742 insertions(+), 22 deletions(-) create mode 100644 frontend/.env.example create mode 100644 frontend/src/components/RequireAuth.test.tsx create mode 100644 frontend/src/components/RequireAuth.tsx create mode 100644 frontend/src/screens/LoginScreen.test.tsx create mode 100644 frontend/src/screens/LoginScreen.tsx create mode 100644 frontend/src/screens/SettingsScreen.test.tsx create mode 100644 frontend/src/services/__tests__/api.test.ts create mode 100644 frontend/src/services/__tests__/apiClient.test.ts create mode 100644 frontend/src/services/api.ts create mode 100644 frontend/src/services/apiClient.ts create mode 100644 frontend/src/services/auth.ts create mode 100644 frontend/src/services/dataSource.ts diff --git a/docs/runbook.md b/docs/runbook.md index ccb4326..605809d 100644 --- a/docs/runbook.md +++ b/docs/runbook.md @@ -49,6 +49,28 @@ Failed logins are always a generic `401 {"detail":"Invalid email or password"}` — the API never reveals whether the email exists.
