# Changelog: GTM Engineering Corpus

Versions use YYYY.MM. This file mirrors CORPUS_CHANGELOG in src/data/corpus-meta.ts; the generator's --check fails when a version listed there is missing here. Record counts and hashes for each release are in https://artemisgtm.ai/corpus/index.json.

## 2026.10 (2026-10-18)

First release. Three record files built from the TypeScript that renders the HTML pages: GTM systems patterns, pipeline debugging scenarios and teardown rubric checks, cross-referenced by stable @id, with sha256 hashes and record counts in index.json.
