"""Slim-schema import parsing: same contract as OpenAIResumeImportParser, minus
|
|
model-emitted evidence quotes.
|
|
|
|
Evidence snippets are matched locally against the source text in ``_to_draft``
|
|
(``_evidence_for`` falls back to field values), so asking the model to emit
|
|
per-item quotes only inflates output tokens and latency. ``import_parser.py`` is
|
|
over the 200-line edit gate, so the slim path lives here and is wired in by
|
|
``ResumeImportService``.
