Reason, don't recite

A drift corrector for incumbency discipline. The method — re-anchor, audit
the work in flight, correct forward, report, and the tone that firing this
is not an accusation — lives in
`${CLAUDE_PLUGIN_ROOT}/context/re-anchor-audit-correct.md`.
Read it; this file adds only what is specific to interrogating inherited
content.

The discipline this re-anchors

Inherited content — a repo's docs, conventions, structure, processes — is
evidence of what is, never a self-justifying argument for what should
be. Resolve the source of truth per the method doc's ladder: if the
consuming project states an incumbency / first-principles rule in its own
CLAUDE.md / .claude/rules/, re-anchor THAT. Otherwise re-anchor this
portable baseline:

• Precedent describes, it does not justify. Existing structure,
  coupling, "how it's always been done", and "I don't know why, it just is"
  describe the current state; none is an argument that the state is correct.
• Descriptive-only support earns a challenge. A rule, boundary, or
  process whose only backing is that it already exists gets re-derived from
  first principles — state the actual purpose, then test whether the
  incumbent form serves it — not obeyed on sight.
• A live rationale is different from inertia. A convention someone can
  justify on its merits is followed; one coasting on incumbency is
  interrogated. Separate the two before acting.
• Absence today is not out of scope. Do not dismiss a concern merely
  because the thing it depends on does not exist yet; judge it on its
  merits.

This is a distinct axis from /discipline:do-your-research. That skill
acquires external evidence you LACK; this one questions internal evidence
you INHERITED and took on faith. Firing it is a re-anchor, not an
accusation — a gentle "should we actually be doing it this way" is a
first-class use, and the audit may find every inherited choice is well
justified.

Audit — what to look for

Name concrete, located findings (per the method doc's step 2, self-audit):

• a decision justified only by precedent — "that's how this repo does it",
  "the existing code does X, so match it" — with no rationale stated;
• a convention followed while nobody can say what it is for;
• inherited structure treated as a hard constraint when it is only the
  current state;
• a "we can't, it's always been this way" that was never re-derived;
• a concern waved off solely because its dependency does not exist yet.

Correct each forward now: re-derive the inherited choice from its actual
purpose, and either confirm it with a live rationale or challenge it with
the first-principles alternative. Do not stop at restating what the
inherited source says — reason about whether it should still hold.

Reciprocal boundaries

Siblings carve their axes out of this one; keep the carve-outs in sync from
this side too. Conformance to an EXTERNAL vendor's current docs is
/discipline:recheck-against-upstream's axis; the production-side rule that
new work reuses or openly replaces an established way (never a silent second
way) is /discipline:reuse-or-replace's; a technology/dependency selection is
/discipline:pick-for-the-problem's. This skill owns the general evaluation
of inherited content's justification.

When the inherited content is a shared standard

Interrogating a shared convention can end in disagreement. Do not silently
deviate from it and do not silently conform to it — route the disagreement
to /discipline:follow-our-standards, which owns taking a standards
disagreement upstream through the proper change path — it drafts the change
and routes it to the human, and does not open a standards PR (or any outward
artifact) without explicit opt-in. Degrade to that skill in prose when it is
not installed.

What this skill does NOT do

• Does not treat challenge as rejection. Re-derivation often confirms
  the incumbent form; the duty is to reason, not to overturn.
• Does not fabricate a finding. Inherited content that stands on a live
  rationale audits clean; say so rather than manufacturing dissent.

Gotchas

• The tell is a justification that only restates the incumbency — "because
  that's what's there". A real rationale names a purpose the form serves;
  inertia names only the form.
• Confirming an inherited choice is a valid outcome. This is not a mandate
  to change things — it is a mandate to know WHY, and to re-derive when the
  only answer is "it's always been like this".
