43cf9b0Claude1/**
ba93444Claude2 * BLK-016 — Crontech deploy webhook sender.
43cf9b0Claude3 *
ba93444Claude4 * Asserts that `triggerCrontechDeploy` (in `src/hooks/post-receive.ts`)
5 * matches the wire contract documented at the top of that helper, which
6 * is the inbound contract for Crontech's
7 * `apps/api/src/webhooks/gluecron-push.ts` receiver:
43cf9b0Claude8 *
ba93444Claude9 * POST https://crontech.ai/api/webhooks/gluecron-push
43cf9b0Claude10 * Content-Type: application/json
ba93444Claude11 * X-Gluecron-Signature: sha256=<hex(hmac-sha256(body, secret))>
12 *
13 * body = {
14 * event: "push",
15 * repository: { full_name },
16 * ref, after, before,
17 * pusher: { name, email },
18 * commits: [...]
19 * }
20 *
21 * Plus at-least-once delivery: 5 attempts on 5xx with exponential backoff,
22 * stop on first 2xx or unrecoverable 4xx.
43cf9b0Claude23 *
24 * The helper swallows DB errors, so these tests work without a real DB.
