name: 'PII NER tier E2E (live GGUF, CPU)'

# Runs the real privacy-filter GGUF NER tier end-to-end on CPU — the gap the
# hermetic tests/e2e suite cannot cover (it only exercises the in-process
# pattern tier). Heavy (builds the C++ backend image + downloads a ~2.7 GB
# GGUF), so it is path-filtered on PRs and otherwise runs nightly / on demand.
#
# This drives the container-level harness (tests/e2e-backends) via
# `make test-extra-backend-privacy-filter`: it builds the privacy-filter image,
# downloads the model, loads it on CPU, and asserts byte-correct, UTF-8-aligned
# TokenClassify spans. The complementary HTTP-path specs in tests/e2e
# (e2e_pii_ner_test.go) Skip unless PII_NER_MODEL_GGUF is wired.
