-# NOTE: This derivation works around two open bun2nix bugs. Remove the
-# workarounds and simplify once they are fixed upstream.
-#
-# Bug 1 — missing .npm manifest cache files
-# https://github.com/nix-community/bun2nix/issues/77
-#
-#   bun's install cache requires two kinds of entries per package:
-#     - the extracted package directory (e.g. handlebars@4.7.9@@@1/)
-#     - a hashed .npm manifest file (e.g. 02dd05ab1686ff3a.npm)
-#   bun2nix only provides the former. bun therefore fetches the manifest from
-#   the registry during the "Resolving" phase, which fails in the Nix sandbox.
-#
-#   Workaround: pass --offline to bun install. This tells bun to skip manifest
-#   fetches and trust the lockfile for resolution instead.
-#
-# Bug 2 — catalog: specifiers still trigger network resolution with --offline
-# https://github.com/nix-community/bun2nix/issues/77 (same thread)
-#
-#   bun2nix's bunResolveCatalogRefs rewrites "catalog:" specifiers in
-#   package.json to the version *range* from the catalog table (e.g. "^1.3.14")
-#   rather than the exact pinned version from bun.lock's packages section.
-#   Even with --offline, bun reads the catalog table from bun.lock and tries to
-#   resolve those ranges, hitting the network.
-#
-#   Workaround: the Python script below pre-processes the source before the
-#   build. It pins every dep in every workspace package.json to the exact
-#   version from bun.lock's packages section (so no ranges remain for bun to
-#   resolve), and strips the catalog/catalogs keys from bun.lock entirely.
-#
-#   bun.lock is JSONC (trailing-comma JSON) so we parse it with Python's stdlib
-#   json after stripping trailing commas with a regex.
-#
-# Additionally, oh-my-pi's bun.lock was generated with bun >=1.3.14 which uses
-# a different Wyhash seed for cache keys than nixpkgs's bun 1.3.13. Bumping bun
-# globally breaks other packages (e.g. opencode), so instead we patch the
-# generated wrapper script in postInstall to reference bun 1.3.14 directly.
-# Hashes from https://github.com/NixOS/nixpkgs/pull/519796
