The profile fields (`candidate_name`, `job_title`, `current_company`,
`years_experience`) are extracted from the resume by the model and are `null`
whenever the resume does not state them. `years_experience` uses the total stated in
the resume when there is one, otherwise it is computed from explicitly stated dates —
never guessed. `matched_keywords` are verified server-side against the resume text;
a keyword the resume never mentions is dropped rather than shown as evidence.

Normalizing before the length ceiling is enforced means a model that returns 31 near-duplicate keywords collapses under the limit instead of failing the candidate.
After a result parses, the orchestration layer verifies matched_keywords against the resume text (verify_matched_keywords in services/scoring.py): any keyword with no case-, separator- and trailing-plural-insensitive occurrence in the resume is dropped, and the drop count is logged as dropped_keywords on the candidate_scored line. A matched keyword is an evidence pointer a recruiter will read as "this is in the CV" — QA found the model fabricating ~2.5% of them (e.g. crediting Docker to a resume that never mentions it). Semantic equivalences may still inform the score and critique; they just cannot appear in the matched list. missing_keywords are JD-side and are not filtered.

Revision history Revision history
Revision 5 — hardening after a QA audit over real CVs found three defects. (1) Fabricated matched keywords (~2.5% rate): fixed with server-side verification in the orchestration layer plus a resume's-own-spelling prompt rule — see the verify_matched_keywords paragraph above. (2) Gibberish JDs scored confidently (a mojibake JD outscored the real one): fixed with an unintelligible-JD → score 0 prompt rule. (3) Profile extraction flipped between runs (title header vs latest role; stated years vs recomputed): fixed with source-priority prompt rules. The dropped_keywords log key was added to the logging allowlist.
Revision 4 — added the browser test UI and candidate profile extraction at the user's request. GET / serves a static card-grid page (app/static/index.html) straight from the package — no build step, no new dependency, kept out of the OpenAPI schema. ATSScore gained four nullable profile fields (candidate_name, job_title, current_company, years_experience) extracted by the model alongside scoring; the system prompt gained a matching extraction section. Nullability is the contract: a resume that does not state a field yields null, and years_experience is computed only from explicit dates or durations. The live smoke test verified the extended schema is accepted by structured outputs.
Revision 3 — switched provider from Anthropic to OpenAI at the user's request. The architecture was unchanged: the Scorer protocol absorbed the swap, and models, PDF handling, orchestration, routing, and logging were untouched.

"""Live positive/negative scoring audit over real CVs.
Runs the full FastAPI stack in-process (real PDF extraction, real OpenAI calls) and
checks that scores move the way an ATS should:
* positive job descriptions (roles the CVs actually fit) score high,
* negative job descriptions (unrelated or adjacent roles) score low,
* a prompt-injection payload inside a job description changes nothing,
* malformed requests and unreadable PDFs fail with the documented status codes
without sinking the rest of the batch.
Usage:
