# 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
> historical record, not a phantom. `/source-grounding-audit` still resolves via the deprecated redirect
> stub at `plugins/fh-meta/skills/source-grounding-audit/SKILL.md` (`successor: phantom-quench`).
> 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).

> **Quench-series semantics** (resolves the "quench *what*?" question): each member subjects a different
> thing to the forge — steel-quench hardens an **existing output**; phantom-quench hardens the system
> against **mistaking the absent for present** (the phantom illusion — *not* the phantom as a material to
> harden); goal-quench hardens the **goal itself** into an advanced version. Same verb, consistent grammar.
