How to use

Run from the Fear-of-Falling subproject root or repo root.

Example:

Rscript .codex/skills/fof-qc-summarizer/scripts/qc_summarize.R

Optional overrides:

Rscript .codex/skills/fof-qc-summarizer/scripts/qc_summarize.R --qc-dir PATH --out-dir PATH --script-label K18_QC_SUMMARY

Inputs

  • QC outputs under Fear-of-Falling/R-scripts/K18/outputs/K18_QC/qc/.
  • Manifest helpers discovered by scanning for init.R with append_manifest() and manifest_row().
  • Policy sources: Fear-of-Falling/CLAUDE.md, Fear-of-Falling/QC_CHECKLIST.md.

Outputs

  • Fear-of-Falling/R-scripts/K18/outputs/K18_QC/qc_summary/qc_summary.csv
  • Fear-of-Falling/R-scripts/K18/outputs/K18_QC/qc_summary/qc_summary.txt
  • One manifest row per new artifact (if manifest format is confirmed).

Failure modes

  • Fear-of-Falling project root not found.
  • QC outputs directory missing.
  • Manifest helpers missing.
  • Manifest header mismatch (fail closed).
  • No eligible aggregate QC artifacts to summarize.

Safety/guardrails

  • FAIL CLOSED: if manifest helpers or format are not verifiable, the script exits 1.
  • Privacy: skips any file with ids, row_level, or participant in the name or an id-like column; never writes participant-level rows.
  • No external APIs or network calls.
  • Does not modify raw data or QC inputs.
