1// End-to-end security checks of the GitHub-compatible REST API, against a real
2// `wrangler dev` Worker with real (seeded) accounts, tokens and sessions.
3//
4// pnpm --filter @diffinery/app e2e
5//
6// Covers: search only shows what the caller may read (pending, disabled and
7// orphaned-agent callers see nothing); agents can't turn a failing required
8// check green; deployments verify every context; agents can't manage
9// environments or dismiss reviews; secrets default environments to protected
10// branches; locked conversations and archived repositories refuse changes;
11// draft releases stay off readers' live sockets; unsafe tree names, tree bombs,
12// long search queries and percent signs in label names. Anonymous callers and
13// read-scoped tokens can't write; agents can't change secrets or variables;
14// merges honour linear history, need an explicit admin bypass, and drafts can
15// be marked ready; the exact branch protection rule wins over a pattern.
16// Push protection also covers commits made without git (web editor, REST, MCP).
17// Repository-limited tokens can't mint wider ones; settings changed through the
18// API are audited; readers' labels and assignees are dropped. Repository
19// transfers keep a repository's data and leave redirects (web, REST, git, MCP,
20// images) that only readers can follow; emptied organizations can be deleted.
21// Agents land changes on protected branches only through auto-merge (or the
22// merge queue) where a person allowed it and a required check gates it, never by bypass.
23// Continued in security-limits.test.mjs (environment reviewers, quotas, kill switches, the image
24// proxy), which runs beside this file on a server of its own; the setup is in security-harness.mjs.
