2a9168a1b4 chore(tasks): research-backed decisions to close open tasks (#71/#42/#14/#76/#70)
Per chaim's directive — for decisions not requiring Dafna/chaim, decide after
>=3 authoritative open sources.

#71 DONE — resolved by #15's weight fix (measured: all multi-relevant docs now
  in top-10, the rank-15/16 weak queries fixed). Research (6 sources) said
  enable rerank; tested empirically → it HURT (nDCG@5 0.879 vs 0.960, MRR 0.867
  vs 0.954) because recall is saturated and the cross-encoder demotes exact
  known-item matches. Measurement overrides theory: no rerank, no limit change.
#42 CANCELLED — obviated by BM25 hybrid (already on; handles abbreviation
  tokens lexically); 0 abbrev queries in eval, recall ~0.99, no measured gap.
#14 DEFERRED (reviewed) — no current blocker; YAGNI; trigger documented.
#76 CANCELLED — upstream Paperclip bug (ee=companyId), not safely fixable our
  side; workaround + #78 documented.
#70 — research-backed normalization (ECLI/Akoma Ntoso/ELI/OpenCitations +
  Christen). Applied 3 deterministic mechanical fixes to cited_only (whitespace
  + missing prefix-space); 0 malformed remain. 4 ambiguous items (2 garbled,
  'ערר אדלר', 1 combined citation) flagged for chair — NOT auto-guessed, per
  the entity-resolution false-merge guardrail.

#80 stays pending — human-gated (Dafna value-labeling + chaim cost).
