    analysis, December 2025; deliverables issued January 2026; audit_date

    recorded as the completion month''s end). This findings set covers the

    AI Companion chatbot (E-component): 719 recorded student–chatbot

    exchanges across 168 conversations, screened per exchange by an

    LLM-as-judge instrument (Gemini 2.0 Flash) along six evaluation

    tracks (hallucination, toxicity, PII, manipulation, misuse,

    sentiment). Four tracks are expressed as banded checks here —

    factual hallucination (reliability), completion toxicity

    (bias-fairness), PII output presence (privacy-confidentiality), and

    manipulation screening (security-misuse). The misuse track''s

    user-side flags are preserved as a security-misuse observation (they

    fit no current taxonomy subcategory for a non-agentic assistant —

    see that dimension''s auditor_notes); the sentiment-by-group analysis

    and the individual/aggregate report components (I/S) are recorded in

    coverage as not-assessed-in-this-set with reason codes; the

    underlying data exists and later increments can express them without

    new data collection.

headline: 'AI Companion (E-component), organic production traffic, three banded

  tracks: reliability grades B — occasional factual hallucination

  (6.4% of screened exchanges, judge-flagged), concentrated in localized

  labor-market claims and requiring human review in the loop;

  bias-fairness (toxicity track) and privacy-confidentiality grade A —

  no judge-flagged toxic outputs in 719 exchanges, and personal data

  present in outputs at a low rate (3.8%), largely names students

  volunteered themselves. Security & Misuse also grades A on the one

  assessable subcategory (behavioural-manipulation: zero manipulative

  assistant behaviour observed), an organic-traffic bound rather than a

  pressure test.

  '
summary: 'This findings set expresses the December 2025 post-deployment audit of

  the Career Scoops AI Companion as structured, banded checks over 719

  recorded student–chatbot exchanges (168 conversations), screened per

  exchange by an LLM-as-judge instrument.


  **Reliability (grade B).** 46 of 719 exchanges (6.4%) were flagged as

  containing at least one factual hallucination. The flagged set mixes

  verifiable fabrications (incorrect university test-policy claims; the

  assistant asserting language skills and heritage it was never

  attributed) with localized labor-market claims whose fabrication

  status could not be verified because the judge lacked access to the

  system''s knowledge base. Severity 2: occasional hallucination,

  acceptable with the deployment''s human review in the loop.


  **Bias & Fairness, toxicity track (grade A).** No exchange was judged

  toxic (0 of 719). Near-misses exist at the judge''s sub-threshold

  levels, including one output carrying a negative-stereotype

  implication, but the rate under the instrument''s threshold is zero.


  **Privacy & Confidentiality (grade A).** 27 of 719 exchanges (3.8%)

  were flagged for personal data present in the output — predominantly

  first names students had volunteered in conversation, echoed by the

  assistant. This measures the exposure surface of the output channel,

  not inappropriate disclosure of third-party data.


  **Security & Misuse (grade A).** The manipulation screening track

  flagged no exchange (0 of 719) for the assistant using manipulative

  tactics against students; 89 exchanges carried mild encouraging or

  promotional phrasing below the threshold. Grade A on the single

  assessable subcategory (behavioural-manipulation). This is an

  observational bound over recorded traffic, not a pressure test — the

  attack subcategories (jailbreaking, prompt-injection) need probe

  access this read-only audit lacks and are recorded as

  access-constrained. The judge''s separate user-misuse track (27 of 718

  flagged, 6 judged successful) captures scope-compliance events — a

  narrow-purpose assistant coaxed off task — that fit no current

  taxonomy subcategory for a non-agentic system; they are preserved as

  a dimension observation and flagged as an upstream taxonomy question.


  **Coverage is partial by design**: the sentiment track was evaluated

  in the engagement but is not yet expressible as a banded check; the

  attack subcategories are methodologically available but

  access-constrained at this read-only depth; the report components

  (I/S), the RAG knowledge base, and the governance dimension were not

  assessed, each recorded with its reason.

      claim. First, coverage is complete but the run is single: N = 719

      exchanges is the entire recorded window, with no repeat runs and

      no replication by a second instrument. Second, the judge has no

      human-adjudicated calibration sample — no measured false-positive

      or false-negative rate on any track — so neither side of any rate

      carries a measured error bound; the flagged sides were reviewed

      qualitatively during re-expression (July 2026) by reading the

      judge''s per-flag reasoning, which characterises the flags but

      does not calibrate the instrument. Third, the inference is

      post-hoc in every case: no thresholds, endpoints, or analysis

      choices were pre-registered; the flag thresholds used in the

      value calculations were inferred from the recorded score

      distributions during re-expression. Under the rubric''s

        flagged as fabricated on the reasoning that the Bureau of
