Compose-ready workspace: packages/zappier (rate card, portal, Stripe),
packages/verae-zapier-middleware (timestamp + NATS), packages/verae-zapier
(CLI app), vendor/zapier-platform, and research/zapier vendor corpus.

Gate 0 structure checks pass. Product code and research are not yet wired.

+
+## cli
+
+* 🐛 `zapier init` Typescript template OAuth2 implementation doesn't work out of the box ([#1022](https://github.com/zapier/zapier-platform/pull/1022))
+* 🐛 `version-store.js` is updated to show the Node and NPM versions for v17 ([#1020](https://github.com/zapier/zapier-platform/pull/1020))
+
+## core
+
+* 🐛 `zapier build` (and therefore also `zapier push`) hangs on the `Building app definition.json` step when it's run on an integration with a Core dependency of v17, and run via CLI with a version less than v17 ([#1020](https://github.com/zapier/zapier-platform/pull/1020))
