What does this PR do?

loadConfig opened the credentials file before resolving explicit configuration, so even a complete environment/endpoint override failed when an unused credentials path was unreadable or a directory. Validate the resolved profile name first, resolve the explicit key and endpoint, and read the selected profile only if either field still needs fallback.

Blank environment values, endpoint/profile precedence and filesystem errors when fallback is needed are preserved. No filesystem errors are broadly caught.

• New behavior is covered by unit tests (no network or credentials required).
• No secrets, API keys, internal endpoints, or personal data are included.

Notes for reviewers

Four config regressions fail on the unchanged baseline; all 29 config tests pass after the fix. They cover complete environment overrides, key-plus-endpoint flag, flag precedence, EISDIR/EACCES, partial and blank overrides that still require file fallback, malformed profiles, and fallback from the selected readable profile. The chmod-based EACCES test is POSIX-only and independently proves that the fixture is unreadable; the remaining controls are portable.

An independent six-case regression and six loopback CLI calls also change from reproducing the defect to passing, including normal/repaired-store controls. No TestSprite services or credits were used.

Validation on Node 22/Linux: lint, Prettier, types, build, full coverage suite and local E2E. Remote cross-platform CI remains to be run.

Summary by CodeRabbit

• Bug Fixes

  • Configuration now works with a complete API URL and API key override even when the credentials file cannot be read.
  • Missing configuration values continue to fall back to the selected profile, while invalid profile selections are rejected.
  • Diagnostics can proceed with complete overrides despite an unreadable credentials file; incomplete overrides still report an error.
  • API URL selection continues to follow the order of explicit settings, environment variables, saved credentials, and the default.

• Tests

  • Expanded coverage for configuration fallback, profile validation, diagnostics, and credentials-file errors.

Walkthrough

loadConfig validates profiles and skips credential-file access when both API values are supplied. runDoctor classifies unreadable credential files as warnings only for complete overrides. Tests cover precedence, fallback, validation, and diagnostics.

Changes

Credential Resolution

Layer / File(s)	Summary
Profile validation and conditional credential fallback src/lib/config.ts, src/lib/config.test.ts	loadConfig validates the selected profile, skips credential reads for complete API key and URL overrides, and preserves fallback behavior for missing values. Tests cover precedence, trimming, profile validation, and filesystem errors.
Unreadable credential diagnostics src/commands/doctor.ts, src/commands/doctor.test.ts	runDoctor probes the credentials file and passes override completeness to checkCredentials. Complete overrides produce a warning for unreadable credentials; incomplete overrides produce a failure. Tests cover connectivity, tunnel checks, messaging, and read failures.

Explanation

Issue #536 requires complete key and endpoint overrides to avoid reading the credentials file. loadConfig now validates the selected profile, resolves explicit values first, and calls readProfile only when a field needs fallback. The changes preserve profile, endpoint, blank-value, precedence, malformed-profile, and fallback error behavior. Config tests cover complete overrides, partial overrides, directory errors, invalid profiles, and profile fallback. Doctor tests cover complete and incomplete overrides.

Full details: Out of Scope Changes check

Explanation

The changes remain connected to issue #536. The loadConfig changes and tests implement the requested configuration behavior. The doctor changes retain credential-store diagnostics while allowing complete overrides to proceed and pass the resolved config to connectivity checks. The implementation catches only permission errors for this diagnostic path. No ACL change, broad filesystem suppression, new option, or unrelated server behavior is shown.

Replaced the mode-000 dependency with a path-specific EACCES injection in the unreadable-store unit test. Complete key/endpoint overrides assert that no read occurs; a subsequent partial override asserts that the credential read still throws. Other filesystem operations use the real implementation, and the spy is restored afterward. This also lets the unit case run on Windows without relying on POSIX permissions.

The revised regression fails against the original loadConfig (4 failing cases, 25 passing controls) and all 29 config cases pass with the fix. The updated commit passes lint, Prettier, types, build, the full coverage suite, and local E2E on Node 22/Linux. The earlier real-permission CLI evidence was run without DAC bypass capabilities; it remains separate from this deterministic unit test.

The entry checkbox is checked, but the entry workflow reports HttpError: Resource not accessible by integration and has no bot confirmation. Fork CI, coverage, and security workflows await maintainer approval; entry and remote validation remain pending.

[walter-w-white]

Addressed the additional doctor scope in fa3d882.

doctor now checks the credentials file directly even when loadConfig can use complete overrides without reading it. An unreadable store is a warning when both the key and endpoint come from env/flags; incomplete overrides fail the credentials check and no longer promise that commands still work. Connectivity and tunnel checks continue using the resolved configuration.

The regression verifies that normal config resolution succeeds without a credential read while doctor still reports the unreadable file. It covers complete env overrides, an endpoint flag with a blank env URL, incomplete/blank overrides, and a real unreadable file. Before the doctor change, the updated doctor suite had five failing assertions and 23 passing cases; afterward, all 66 doctor, tunnel and config tests passed.

The committed change passes lint, formatting, types, build, the full coverage suite (4,818 passed, two skipped), and local E2E (110 passed, one skipped) on Node 22/Linux. All four coverage measures exceed 80%. Real file-permission checks ran without DAC bypass capabilities. Hosted CI and Season 4 entry confirmation remain pending; local checks do not establish either.

Pushed 6c66748 to address the six changed-line security-lint findings in the existing config/doctor tests. Each filesystem call now has a line-specific justification for its controlled temporary fixture path, following the workflow's guidance. No runtime behavior or dependencies changed.

The changed-line security lint and all six required local checks pass on this commit: lint, format, types, build, coverage and local E2E. The newly pushed commit still needs its own GitHub workflow results. CI and Test Coverage passed on the previous head; those results do not certify this new SHA.

The other Security failure is Dependency Audit, which flags the existing undici 7.29.1 lockfile entry. Both dependency manifests remain unchanged, and the lockfile is byte-identical to current main (a18d37c); that audit blocker needs a base dependency update.

[walter-w-white]

Synced the upstream dependency update from #355 in 69dbd5d. Both dependency manifests now match main (5281202), including undici 7.30.1. The config/doctor fix and regression patch is unchanged.

Production audit reports zero vulnerabilities. Changed-line security lint and all six required local checks pass on this commit (Node 22/Linux), including full coverage and local E2E. Hosted checks for this new SHA still need verification.
