---

name: fof-qc-summarizer description: Aggregate-only summarizer for K18 QC artifacts; produces summary outputs and appends manifest rows when format is confirmed. metadata: short-description: Aggregate-only QC summarizer for K18 outputs.

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.
