e2e: mint GitHub App installation token instead of PAT secret#23
Merged
Conversation
Phase 0 spike (#22) verified installation tokens work against the hosted MCP endpoint. Drops the E2E_GHPOOL_PAT long-lived secret dependency; the token is now short-lived and minted per run from APP_ID/APP_PRIVATE_KEY. create-github-app-token fails loudly if secrets are absent, preserving the fail-fast property from the #21 review.

Summary
Phase 0 spike (#22) verified that GitHub App installation tokens are accepted by
api.githubcopilot.com. This switches the E2E workflow's credential from the long-livedE2E_GHPOOL_PATsecret (currently an OAuth token that rotates withghre-auth — a latent CI breakage) to a short-lived installation token minted per run from the existingAPP_ID/APP_PRIVATE_KEYsecrets.Changes
