ssotchk

Find every place a single truth lives, name its rightful home, and report the drift — without changing anything.

Goal

Locate Single-Source-of-Truth (SSOT) violations: one fact duplicated, paraphrased, or contradicted across artifacts or platforms. A fact with N copies carries N-1 liabilities, because copies drift out of sync. The output is a map — where it lives, which copy should be canonical, and what to do with the rest — that ssotize or a human can act on. This is read-only.

Reach for this when establishing order across many artifacts, especially messy or legacy states; once a fact is cleanly SSOT'd, it needs upkeep, not another consolidation.

Workflow

1. Name the truth in scope — the specific fact, value, spec, decision, status, or definition being tracked, not the whole document.
2. Enumerate every occurrence across the given artifacts and platforms.
3. Classify each occurrence: exact copy, paraphrase, partial, stale, or contradictory.
4. Pick the canonical home — the most authoritative and most-maintained location, closest to where the fact actually changes (the code/config for a value, the spec for a decision, the ticket for status); never arbitrarily.
5. Decide the action per non-canonical occurrence: dedupe (redundant copy), reference (docs should link to canonical, code should import/source/include it, config should use a shared read), or reconcile (it disagrees — needs a human call on which is right).
6. Report: a table of occurrences (location · kind · action), the proposed canonical home with a one-line justification, and a separate list of contradictions/drift that need a decision.

Rules

• Read-only. Propose; do not edit, move, or delete.
• An empty findings list is a valid result — never invent drift to fill the report.
• Keep contradictions separate from plain duplicates; never silently decide which conflicting value is "true".
• Flag any detail that lives ONLY in a non-canonical copy — it must be folded into the canonical home before that copy can be cut.
• Respect boundaries: surface (don't ignore) when copies span trust/permission scopes — private vs public, internal vs customer-facing.
• Be platform-aware: some places can transclude, some only link, some need a quote plus a link.

Verification

Before finishing:

1. Re-enumerate by a second method — a different search term, synonym, or tool — and confirm it surfaces no occurrence the report missed. Completeness is the core SSOT risk: a copy you never found is a copy that will drift.
2. The canonical home is justified, not assumed.
3. The report is actionable: a human or ssotize could execute it without re-discovering anything.
