"""Recommendation Layer.

Maps a :class:`ScoreResult` plus the match data into a verdict with
short reasoning, strengths, concerns, and connect guidance.

Rules from the build plan:

* Verdict bands: 80+ Strongly Proceed, 65-79 Proceed,
  50-64 Proceed with Caution, otherwise Do Not Proceed.
* LOW confidence softens the verdict by exactly one tier.
* The main "why" is capped at two lines so the user can scan it.

When a :class:`~app.config.Settings` instance is supplied and an API
key is configured, the recommendation reasoning, connects advice, and
best proposal angle come from the LLM (task ``recommendation_generation``).
The verdict band itself stays deterministic — the LLM never overrides
which tier the score falls in.

  - "why": at most TWO lines (separated by a single newline). Each line

  - "concerns": list of 1 to 2 strings (short, scannable)
  - "connects_recommendation": one short line of credit/connects advice

Hard rules:
- Do not invent metrics, clients, projects, or proof points.
- Keep "why" to two lines maximum.
- Set "verdict" to: {expected_verdict}
- Use the strengths and concerns lists as starting points — refine for
  clarity but do not add unsupported claims.
- A single point must NEVER appear in both "match_strengths" and
  "concerns". The two lists must be distinct — never repeat the same
  point on both sides.

    Deterministic by default. When ``settings`` carries an API key, the
    LLM is asked for the natural-language reasoning, connects advice,
    and proposal angle; the verdict tier itself is always determined by
    the deterministic score+confidence rule (``verdict_for_score`` +
    one-tier softening on LOW confidence).

    When ``beginner_eval`` (from
    :func:`app.services.beginner_evaluator.evaluate`) is supplied it is
    layered on deterministically: an Instant No overrides the verdict to
    "Do Not Proceed"; a "Proceed With Caution" result caps the verdict so
    it can never read better than "Proceed with Caution"; an
    "Apply Confidently" result leaves a strong score's verdict intact and
    shapes the connects advice. Omitting it preserves the original
    behaviour for callers that don't run the checklist.
