nixpacks.toml

# Railway relay build config (root_dir="" — builds from repo root).
# Promotes scripts/nixpacks.toml settings here since nixpacks only reads
# config from the build root. Adds scripts/ dep install so that packages
# in scripts/package.json (e.g. @anthropic-ai/sdk, fast-xml-parser) are
# available at runtime when node scripts/ais-relay.cjs is started.

[phases.setup]
# aptPkgs = ["curl"]  — disabled; NIXPACKS' apt wrapper runs
# `apt-get update && apt-get install` which fails hard when Ubuntu's
# package-index CDN returns a hash mismatch (2026-04-17: noble-security
# mirror globally broken, blocking ALL Railway NIXPACKS builds). The
# manual cmds below tolerate transient mirror failures by adding
# --fix-missing and allowing partial index updates to succeed.
