Schuknecht and Gacek 1993 grounding log

Attempt 1 — STRC QMD exact-title search

  • Retrieved: 2026-08-21
  • Exact query: qmd search ""Cochlear pathology in presbycusis"" -c strc -n 10
  • Index: /Users/egorlyfar/.cache/qmd/index.sqlite; collection qmd://strc/
  • Result: no results.
  • Verbatim passage relied on: none.
  • Weight: ABSENCE CHECK ONLY. This confirms no exact-title hit in the fresh STRC index; it does not establish what the paper reports.

Attempt 2 — parsed book-corpus exact-title search

  • Retrieved: 2026-08-21
  • Exact query: rag search "\"Cochlear pathology in presbycusis\""
  • Index/path: BookLibrary RAG; Schacht_2008_Auditory-Trauma-Protection-Repair_SHAR31_Springer/.../auto/Schacht_2008_Auditory-Trauma-Protection-Repair_SHAR31_Springer.md, rendered PDF p. 194
  • Source: Schacht et al., Auditory Trauma, Protection, and Repair, Springer, 2008, references, p. 194.
  • Verbatim passage: “Schuknecht HF, Gacek MR (1993) Cochlear pathology in presbycusis. Ann Otol Rhinol Laryngol 102:1–16.”
  • Weight: CITATION-ONLY SECONDARY HIT. It confirms bibliographic existence. It states no OHC-fraction-to-dB calibration pair and is not the primary article.

Attempt 3 — STRC semantic query for the numeric claim

  • Retrieved: 2026-08-21
  • Exact query: qmd query "Schuknecht Gacek 1993 percentage outer hair cell loss threshold shift decibels presbycusis" -c strc -n 8
  • Index: /Users/egorlyfar/.cache/qmd/index.sqlite; collection qmd://strc/
  • Result: query expansion and retrieval reached reranking but returned no completed result (exit_code unavailable in the runner).
  • Verbatim passage relied on: none.
  • Weight: FAILED RETRIEVAL ATTEMPT. It supplies no evidence for any calibration constant.

Attempt 4 — external primary abstract

  • Retrieved: 2026-08-21
  • Exact queries: site:pubmed.ncbi.nlm.nih.gov "Cochlear pathology in presbycusis"; follow-up site:pubmed.ncbi.nlm.nih.gov/8424477 cochlear pathology presbycusis
  • Index/path: web search → PubMed PMID 8420477, https://pubmed.ncbi.nlm.nih.gov/8420477/
  • Source: H. F. Schuknecht and M. R. Gacek, Cochlear pathology in presbycusis, Annals of Otology, Rhinology & Laryngology 102(1 Pt 2), 1993, pp. 1-16; DOI 10.1177/00034894931020S101. Abstract, no page-specific locator.
  • Verbatim passage: “An abrupt high-tone loss signals sensory presbycusis, a flat threshold pattern is indicative of strial presbycusis”.
  • Weight: STATES A QUALITATIVE PATHOLOGY/AUDIOGRAM-SHAPE ASSOCIATION. It does not state the executable scalar pairs, especially 30% functional OHCs → 53 dB, and it concerns mixed human presbycusis rather than STRC rescue.
  • Bridging derivation: none is valid. Audiogram shape by pathology class cannot identify a frequency-agnostic threshold from a whole-cochlea functional-OHC fraction.

Attempt 5 — Anna’s Archive metadata search

  • Retrieved: 2026-08-21
  • Exact query: python3 /Users/egorlyfar/.codex/skills/annas-archive/scripts/search.py search "Cochlear pathology in presbycusis Schuknecht Gacek" --ext pdf --lang en --limit 8
  • Index/path: Anna’s Archive search endpoint through the local skill.
  • Result: HTTP 403 Forbidden; no result/MD5 returned, so no download was possible.
  • Verbatim passage relied on: none.
  • Weight: FAILED RETRIEVAL ATTEMPT.

Attempt 6 — Sci-Hub DOI resolution and full-text fetch

  • Retrieved: 2026-08-21
  • Exact metadata query: python3 /Users/egorlyfar/.codex/skills/sci-hub/scripts/scihub.py info 10.1177/00034894931020S101

  • Verbatim passage relied on: pending MinerU extraction; no claim is taken from the unparsed binary.
  • Weight: PRIMARY PDF RETRIEVED. Retrieval alone does not validate any constant.

  • Source/edition/pages: Schuknecht and Gacek, 1993, article p. 1 of 16 (PDF p. 1), Materials and Methods.
  • Verbatim passage: “The number of cases is too small for statistical analysis; therefore, visual correlations of the audiometric data and cytocochleograms form the basis for our judgments.”
  • Weight: STATES THE METHOD’S LIMIT. The primary paper uses case-specific, tonotopically aligned visual comparisons; it does not estimate a population transfer curve. The exact claim query returned no 0.30 → 53 dB pair, no functional-OHC fraction, and no transduction measure.
  • Variant/bridging derivation: the paper contains frequency-place audiograms and localized pathology, which is a different variable geometry from a scalar whole-cochlea “functional fraction.” No lossless bridge exists from those case charts to any executable pair in CALIBRATION_POINTS; fitting one would require new digitization, unit definitions, confounder control, and a declared statistical model.
