`bun2nix.hook` (used by upstream omp's package.nix) sets
patchPhase = bunPatchPhase
at the end of its setup-hook unless `dontUseBunPatch` is already set.
`bunPatchPhase` only runs `patchShebangs` plus a HOME mktemp; it never
iterates over `$patches`. The standard nixpkgs `patches` attribute
therefore went into the derivation env but was silently ignored at
build time, leaving the deployed omp binary unpatched.
Switch to applying the two patches via `prePatch` (which `bunPatchPhase`
does call). Verified with strings(1) over the rebuilt binary that both
patch hunks land:
/wrong_api_format|...|invalid tool parameters/ (patch 0001)
stubsReasoningContent ... thinkingFormat == "openrouter" (patch 0002)
