From e35f83cd806199b23803407bb2e811f80b2c2ad3 Mon Sep 17 00:00:00 2001 From: Luke Curley Date: Fri, 23 Oct 2026 23:03:47 -0700 Subject: [PATCH 1/3] chore(quest): claim quest/m0/kix/github-fake.md Quest-Claim: 64e456e2f74a458a From 8d953172ac44034a84f52181add5c4d8c19ccefc Mon Sep 17 00:00:00 2001 From: Luke Curley Date: Fri, 23 Oct 2026 23:23:05 -0700 Subject: [PATCH 2/3] test(cloudflare): run publication end to end against the seeded GitHub fake The seeded fake (dev/github.ts) now models commits and trees in a fork network's shared object store, fast-forward and forced branch updates on the upstream and its service fork, pull request listing, creation, updates, and ready-for-review, and the issue and pull request reads a job's context makes. Like GitHub, it scopes each installation token to the repositories and permissions it was minted for, so a write with the wrong token fails. publish.test.ts drops its own stateful fake for this one, with a small world of its own and the shared `intercept` wrapper for lost responses and concurrent changes. The seed test adds a runner that publishes the seeded queued job's commits and pull request, and a retry that adopts the failed import job's pull request, whose fork branch the seed now records. The local server passes request headers to the fake, which needs them for token scoping.
