phantom-quench

Input-tracing grounding audit for artifacts such as test cases, analysis reports, and design docs. Extracts proper nouns, numbers, citations, version claims, and branching conditions, then back-traces each to declared local files by grep or to external sources by fetch-and-support checks. Marks missing anchors as Phantom Claims and cited-but-unsupporting anchors as Unsupported. A claim is grounded only by non-model evidence: a local hit or literal source span, never another model's agreement. Renamed from source-grounding-audit; old-name references still route here. Triggered by: "phantom detection", "phantom claim", "source back-trace", "where did this come from", "verify source", "does the source support this claim", "grounding audit", "source grounding audit", "citation support check".

# phantom-quench — Input Tracing Grounding Audit

> Just because an artifact looks plausible doesn't mean it's grounded in source. plausible ≠ grounded.

> **Renamed from `source-grounding-audit` (2026-06-06)** — the grounding member of the quench series
> (steel-quench · phantom-quench · goal-quench). Same skill, same ruleset; only the label changed to fit
> the family. The **v1 paper (Zenodo 10.5281/zenodo.20397566) cites the old name** — that is the <!-- stale-ref: pinned-line=20397566 -->
> historical record, not a phantom (`paper/forge_harness_v1.0.html` is left unchanged by design; readers
> map *source-grounding-audit (v1) = phantom-quench (current)*). The deprecated redirect stub directory
> was removed 2026-06-12 — old-name utterances ("source grounding audit", "grounding audit") route here
> via this description's trigger phrases.
> This is a **label rename, not a capability change** — phantom-quench does not fuse steel-quench or
> inject faults; those remain separate (orthogonality is deliberate — see Role Separation below).
