[0.17.0] — 2026-06-14 — Human-reviewed gold + honest matching numbers; TED status fix

Changed

• The eval gold is now HUMAN-REVIEWED (was auto-proposed + rule-corrected). Every
  label was checked by hand: expired/closed windows → not, out-of-region items →
  not, over-generous relevant → borderline, plus a few real false positives
  removed and two active borderline positives added where a profile had none. The
  _meta no longer says "pending review".

• Matching numbers re-measured on the strict gold — and they are LOWER, which is the
  point. The earlier auto-proposed gold overstated precision (it counted
  expired/out-of-region items as relevant). Honest figures now (LLM pointwise Haiku):

  min_score	P@5	P@10	recall	FPR
  40 (precision)	0.39	0.34	0.61	0.06
  20 (balanced)	0.35	0.24	0.86	0.21

  (was 0.70 / 0.66 / 0.57 / 0.02 on the lenient gold). The matcher is a low-FPR,
  recall-oriented engine, ~2× the heuristic's precision (heuristic P@5 0.22), with
  wide per-profile variance (costruzioni/sardegna_impresa P@5 1.00; small-pool
  profiles 0.00). README's "Matching quality" section is rewritten to these.

Fixed

• TED: a notice with no submission deadline now maps to closed (not the global
  optimistic "open"). A genuine above-threshold biddable call always states a
  deadline; a TED notice without one is almost always an award/result (already
  closed) or a prior-information notice (not yet biddable) — neither belongs in an
  "open calls" radar. Rule lives in ted.to_opportunities (fixes production live
  too); the eval corpus's 41 deadline-less TED rows were recomputed to closed
  (gold untouched). This was found while reviewing the gold: many corpus items showed
  status: open though the source clearly wasn't biddable.
