ssotize

1Find every copy of one scattered fact, consolidate it into one canonical home after approval, and replace the rest with references.

3## Goal
4 
5One fact has one home, and every other place references it: references do not drift, copies do. `ssotize` establishes or repairs that state in messy, legacy, or freshly scaffolded work. Consolidation is deliberate and loses no information, and it is a one-time repair: once SSOT holds, the fact needs no further consolidation.

7The skill starts as a read-only audit that names the truth, finds every copy, chooses the canonical home, and reports the exact plan. It mutates only after the user approves that plan. The audit and the consolidation stay in one workflow with the approval gate between them, because a separate checker makes the audit easy to skip.

111. **Name the truth** in scope: the specific fact, value, spec, decision, status, or definition being tracked, not the whole document.
122. **Audit read-only.** List every occurrence across the given artifacts and platforms. For the candidate occurrences that are files, run `node scripts/snapshot-candidates.mjs [--json] <path>...` from this skill's folder: it prints path, mtime, size and sha256 per file (directories walked) as a Markdown table, or JSON with `--json`, and exits 2 on a usage error or an unreadable path. Report that table.
