$ ./ekos/target/debug/ekos ask "What does the FooBarNonexistentAnalyzer do?"

[INFO ekos::commands::recover] using local Ollama provider with disk cache
[INFO tantivy::directory::file_watcher] Meta file ".ekos/ledger/facts/search/meta.json" was modified
The FooBarNonexistentAnalyzer does not exist, as it is mentioned in the question. The only available information about this analyzer comes from a search match in the evals/datasets/adversarial.yaml file (claim 1).

# Scenario adv-001 (evals/datasets/adversarial.yaml), should_refuse: true.
# "FooBarNonexistentAnalyzer" is an intentionally-fake name that exists nowhere in EKOS's
# real source — it only appears inside this adversarial scenario's own question text.
# The model DID correctly refuse to fabricate a description (good — no hallucination
# here), but the reason it gives is circular: the only "evidence" it found was the eval's
# own question file, which it should never have been able to see as ledger content in
# the first place. Confirmed directly against the ledger:
#
#   $ ./ekos/target/debug/ekos query find "FooBarNonexistentAnalyzer" --mode lexical
#   1 result(s) for 'FooBarNonexistentAnalyzer':
#     371bd650-ad21-5b60-a618-0bcb3d1165b9  evals/datasets/adversarial.yaml
#
# After the evals/test-runs ignore-pattern fix and full pipeline rebuild, the same
# search returns zero hits (see clean-ledger-verification.txt).
