- core/telemetry.py is now a no-op (no opentelemetry imports); entrypoints
no longer call setup/shutdown telemetry
- Remove all opentelemetry-* deps from pyproject groups; regenerate uv.lock
- Drop otel_exporter_otlp_endpoint/otel_service_name settings; sentry and
auth use "contract-check" instead
- Stop publishing worker metrics ports; bind API metrics to 127.0.0.1 by
default via API_METRICS_BIND_HOST
- Replace otel-collector with Vector in observer profile (docker_logs +
prometheus_scrape -> OpenObserve); add deploy/observability/vector-config.yaml
- Update .env.example, docs (ARCHITECTURE, DEPLOY), README, Makefile
- Rewrite tests/unit/test_telemetry.py for the no-op implementation
- Bump requires-python to >=3.14 and ruff target-version to py314
- Switch all service images to uv:python3.14-trixie-slim builder
and python:3.14-slim-trixie runtime
- Rename libmagic1 -> libmagic1t64 in worker-extract for Trixie
- Regenerate uv.lock under Python 3.14
- Update ARCHITECTURE.md to reflect py3.14 + Trixie
