Wiring the provider exposed that the webhook awaited the interpretation, taking 1-3 s per message. - app/runtime.py builds the worker's rescue runtime once per process (channel, scheduler, workforce, orchestrator, interpreter); the API process no longer builds any of it. - process_inbound_message runs the async handling in the worker with bounded retries; run_due_jobs ticks the scheduler and publishes the degraded-status snapshot to Redis for the API probe; purge_old_messages is finally scheduled. - The webhook validates the signature and enqueues, returning TwiML 200 (500 on broker rejection so Twilio retries instead of silently dropping a message). - /api/status reads configuration (new pure is_provider_configured helper) plus the published snapshot instead of another process's internals. - The FastAPI lifespan ticker is gone: beat owns time. - Tracing bootstrap: the worker installs its own TracerProvider per preforked child and flushes on shutdown. Without it the LLM calls that now happen in the worker produced no Langfuse traces at all (found live, verified fixed: four observations exported for one message). Verified live: webhook 15-50 ms, worker ~2.9 s per message off the request path, two children concurrently without loop errors, beat ticking every 5 s. 296 tests pass, ruff and mypy clean. --- backend/app/agent/factory.py | 48 +++- backend/app/api/status.py | 82 +++++-- backend/app/api/webhooks_twilio.py | 151 ++++--------- backend/app/main.py | 37 +--- backend/app/runtime.py | 129 +++++++++++ backend/app/workers/celery_app.py | 22 +- backend/app/workers/tasks.py | 97 ++++++++- backend/app/workers/tracing_bootstrap.py | 45 ++++ .../tests/unit/api/test_lifespan_scheduler.py | 80 ++----- backend/tests/unit/api/test_status_probe.py | 130 +++++++++++ .../tests/unit/api/test_webhooks_twilio.py | 202 ++++++++--------- backend/tests/unit/test_celery.py | 206 +++++++++++++++++- backend/tests/unit/test_observability.py | 42 ++++ backend/tests/unit/test_runtime.py | 177 +++++++++++++++ docs/adr/ADR-004-llm-provider-selection.md | 12 +- docs/runbook.md | 40 +++- odd/tasks/webhook-offload.md | 74 ++++++- 17 files changed, 1210 insertions(+), 364 deletions(-) create mode 100644 backend/app/runtime.py create mode 100644 backend/app/workers/tracing_bootstrap.py create mode 100644 backend/tests/unit/api/test_status_probe.py create mode 100644 backend/tests/unit/test_runtime.py diff --git a/backend/app/agent/factory.py b/backend/app/agent/factory.py index 19d1d08..3a1daaa 100644 --- a/backend/app/agent/factory.py +++ b/backend/app/agent/factory.py @@ -33,6 +33,16 @@ "bedrock": {"input": 0.0008, "output": 0.004}, } +# Settings attribute and environment variable holding each provider credential. +_CREDENTIAL_SETTINGS: dict[str, str] = { + "openai": "openai_api_key", + "anthropic": "anthropic_api_key", +} +_CREDENTIAL_ENV_VARS: dict[str, str] = { + "openai": "OPENAI_API_KEY", + "anthropic": "ANTHROPIC_API_KEY", +} + class LLMNotConfiguredError(Exception): """Raised when the provider cannot be built (missing credential, unknown @@ -62,11 +72,33 @@ def resolve_price(settings: Settings) -> dict[str, float]: return price +def _missing_credential_reason(settings: Settings) -> str: + """Secret-free reason naming the missing credential variable.""" + var = _CREDENTIAL_ENV_VARS.get(_provider(settings)) + if var is None: + return f"Unknown llm_provider {_provider(settings)!r}" + return f"{var} is not set — add it to backend/.env" + + +def is_provider_configured(settings: Settings) -> bool: + """Pure configuration check (ADR-004): provider enabled **and** its + credential present.

From 1d3890686742856cfdce2efc301761265549abdd Mon Sep 17 00:00:00 2001 From: albert Date: Fri, 25 Sep 2026 13:31:13 +0200 Subject: [PATCH 3/4] 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. Eval run artifacts are now gitignored. --- .gitignore | 3 + backend/app/agent/factory.py | 18 ++- backend/app/agent/interpreter.py | 4 +- backend/app/agent/llm.py | 27 +++-- backend/app/agent/prompts/interpreter_v2.md | 105 +++++++++++++++++ backend/app/agent/schemas.py | 2 +- backend/app/evals/thresholds.py | 94 +++++++++++++++ backend/tests/unit/agent/test_interpreter.py | 6 +- backend/tests/unit/agent/test_llm.py | 38 ++++++ backend/tests/unit/evals/test_thresholds.py | 109 ++++++++++++++++++ ...ADR-002-strands-without-autonomous-loop.md | 2 +- docs/eval-report.md | 66 +++++++++-- evals/runner.py | 20 +--- odd/tasks/interpreter-quality.md | 85 ++++++++++++++ odd/tasks/llm-runtime-wiring.md | 7 +- scripts/eval_summary.py | 32 +++++ 16 files changed, 569 insertions(+), 49 deletions(-) create mode 100644 backend/app/agent/prompts/interpreter_v2.md create mode 100644 backend/app/evals/thresholds.py create mode 100644 backend/tests/unit/evals/test_thresholds.py create mode 100644 odd/tasks/interpreter-quality.md create mode 100644 scripts/eval_summary.py diff --git a/.gitignore b/.gitignore index 093ad69..6073f46 100644 --- a/.gitignore +++ b/.gitignore @@ -36,3 +36,6 @@ Desktop.ini # Local editor state .idea/ .vscode/ +# Eval runs: local artifacts, one per run (sizes and model outputs) +evals/reports/ + diff --git a/backend/app/agent/factory.py b/backend/app/agent/factory.py index 3a1daaa..d7cb075 100644 --- a/backend/app/agent/factory.py +++ b/backend/app/agent/factory.py @@ -15,7 +15,7 @@ import structlog -from app.agent.interpreter import MessageInterpreter +from app.agent.interpreter import PROMPT_VERSION, MessageInterpreter from app.core.config import Settings logger = structlog.get_logger(__name__) @@ -156,9 +156,13 @@ def build_model(settings: Settings) -> Any: return builder(settings, model_id) -def load_system_prompt() -> str: - """Interpreter prompt (baked into the image with the app package).""" - return (Path(__file__).parent / "prompts" / "interpreter_v1.md").read_text(encoding="utf-8") +def load_system_prompt(version: str = PROMPT_VERSION) -> str: + """Interpreter prompt (baked into the image with the app package). + + Prompt edits ship as a new versioned file: the version is recorded on every + interpretation, so a quality change is always attributable to a prompt. + """ + return (Path(__file__).parent / "prompts" / f"{version}.md").read_text(encoding="utf-8") def build_interpreter(settings: Settings) -> MessageInterpreter | None: @@ -198,7 +202,11 @@ def build_interpreter(settings: Settings) -> MessageInterpreter | None: model_id=model_id, price_per_1k=resolve_price(settings), ) - return MessageInterpreter(llm=client, confidence_threshold=settings.llm_confidence_threshold) + return MessageInterpreter( + llm=client, + prompt_version=PROMPT_VERSION, + confidence_threshold=settings.llm_confidence_threshold, + ) def describe_provider(settings: Settings) -> str: diff --git a/backend/app/agent/interpreter.py b/backend/app/agent/interpreter.py index ebe14f3..22b9acd 100644 --- a/backend/app/agent/interpreter.py +++ b/backend/app/agent/interpreter.py @@ -12,6 +12,8 @@ from app.agent.schemas import Interpretation from app.ports import LLMClient +PROMPT_VERSION = "interpreter_v2" + FALLBACK = Interpretation(intent="UNCLEAR", confidence=0.0) @@ -24,7 +26,7 @@ def __init__( self, llm: LLMClient, *, - prompt_version: str = "interpreter_v1", + prompt_version: str = PROMPT_VERSION, confidence_threshold: float = 0.75, max_retries: int = 1, ) -> None: diff --git a/backend/app/agent/llm.py b/backend/app/agent/llm.py index ae896ed..666e10d 100644 --- a/backend/app/agent/llm.py +++ b/backend/app/agent/llm.py @@ -165,15 +165,24 @@ def token(*names: str) -> float: def _build_prompt(self, message_body: str, context: dict[str, Any]) -> str: lines = [message_body] - rescue_id = context.get("rescue_id") - if rescue_id: - lines.append(f"[rescue_id={rescue_id}]") - pending = context.get("pending_offers") - if pending: - lines.append(f"[pending_offers={pending}]") - shifts = context.get("shifts_48h") - if shifts: - lines.append(f"[shifts_48h={shifts}]") + for key in ("rescue_id", "pending_offers", "pending_confirmation", "shifts_48h"): + value = context.get(key) + if value: + lines.append(f"[{key}={value}]") + # The golden set and the orchestrator may carry extra context; drop + # nothing silently — render any remaining non-empty string/list.

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. Reproduced and verified with the Linux CI image (ghcr.io/astral-sh/uv:python3.12-bookworm): 308 passed before the fix, 308 passed and no failures after it. --- backend/app/runtime.py | 6 +++++- backend/tests/unit/test_runtime.py | 29 +++++++++++++++++++++++++---- 2 files changed, 30 insertions(+), 5 deletions(-) diff --git a/backend/app/runtime.py b/backend/app/runtime.py index 7072a3a..438730b 100644 --- a/backend/app/runtime.py +++ b/backend/app/runtime.py @@ -76,7 +76,11 @@ async def handle_inbound(self, from_phone: str, message_sid: str, body: str) -> def build_runtime(settings: Settings) -> RescueRuntime: """Construct the full rescue runtime exactly as the API service did.""" - _, session_factory = create_engine_and_session() # engine lives in the pool + # Pass the database URL explicitly: falling back to the ambient settings + # would make the runtime silently ignore the settings it was given (and + # connect to a developer's local database from tests). + # The engine lives in the pool held by the session factory. + _, session_factory = create_engine_and_session(settings.database_url) channel = TwilioWhatsAppChannel( account_sid=settings.twilio_account_sid, auth_token=settings.twilio_auth_token, diff --git a/backend/tests/unit/test_runtime.py b/backend/tests/unit/test_runtime.py index 4772cd6..3a096ea 100644 --- a/backend/tests/unit/test_runtime.py +++ b/backend/tests/unit/test_runtime.py @@ -3,6 +3,7 @@ All tests are hermetic: SQLite, no provider SDK calls, no network.
