feat(accounts): look up ./.netrc before ~/.netrc for per-project credentials#3844heroku-johnny wants to merge 3 commits into
Conversation
…entials (W-23597907, #1452) When `initNetrc()` loads credentials it now checks for a `.netrc` in `process.cwd()` first. If found, its machine entries are merged into the home `~/.netrc` with local entries taking priority, enabling per-project credential overrides without touching the global netrc file.

add-test-coverage (Testing · important · 60% confidence): It looks like the "cwd .netrc takes priority over home" test pre-populates the cache via setNetrc and mutates machines by hand before calling initNetrc(), so initNetrc returns the cached object without ever exercising the cwd-merge path — the comment even says the merge is "simulated manually," meaning the assertion passes regardless of module behavior. Should we drop the pre-seeded cache so initNetrc() actually reads and merges the cwd .netrc, or assert against the real merge output instead of the hand-built one?

delete-unused-code (Code style · minor · 50% confidence): It looks like cwdStub = stub(process, 'cwd')... is set in beforeEach but never referenced, and process.cwd is never invoked because the tests short-circuit on the cached netrc. Should we remove the stub, or add a test that actually drives the cwd path so it gets used?

Approved. Some comments but nothing blocking on this.
