check between a Spectra glossary and the code that implements it.\n\nYour project keeps two things: a `specs.snapshot.json` (written by `@coder`'s `export_specs` tool and\ncommitted with the code) and `// implements: <Term>` markers in your source. This package checks that\nthe two agree — **offline, with no coordinator running** — so the check works in a bare copy of the\nproject and inside `@coder`'s sandbox alike.\n\nIt catches:\n\n- a marker that isn't comma-separated bare identifiers (put prose on the next line);\n- a marker naming a term the glossary no longer has (renamed or removed);\n- an entity/function/event term that nothing implements (an implementation pass is due).\n\nIt cannot catch a term whose spec was *rewritten* — the marker still names it. That's what each term's\n`hash` in the snapshot is for: refresh the file and `git diff specs.snapshot.json` names the terms\nthat moved, so the test fails loud for structure and review catches the rest.\n\n## Use it\n\nAdd it as a dev-dependency, then write a one-line test in whatever runner you already use:\n\n```ts\nimport { driftCheck } from '@abseed/spectra-drift-check'\nimport { expect, it } from 'vitest'\n\nit('the glossary and the code are in sync', () => {\n  const { ok, findings } = driftCheck({ srcDir: 'src', snapshotPath: 'specs.snapshot.json' })\n  expect(ok, findings.map((f) => f.message).join('\\n')).toBe(true)\n})\n```\n\n`driftCheck` returns `{ ok, findings }`; each finding has a `kind` and a human-readable `message`.\nThe reader functions (`readMarkers`, `readSnapshot`, `implementersOf`) and the pure `checkDrift` are\nexported too, if you want to assemble the check differently.\n\n## Keep the snapshot fresh\n\n`specs.snapshot.json` is a pure function of the glossary (no timestamp), so re-exporting when nothing\nchanged leaves it byte-identical. Have `@coder` run `export_specs` before an implementation pass and\ncommit the result; a stale snapshot is your branch being behind, the way `git status` reports it — a\nsignal to refresh, not a wall.\n","readmeFilename":"README.md"}
