• ClawSweeper keeps one durable marker-backed review comment per issue or PR.
• Re-runs edit this comment so the latest verdict, findings, and automation markers stay together instead of adding duplicate bot comments.
• A fresh review can be triggered by eligible @clawsweeper re-review comments, exact-item GitHub events, scheduled/background review runs, or manual workflow dispatch.
• PR/issue authors and users with repository write access can comment @clawsweeper re-review or @clawsweeper re-run on an open PR or issue to request a fresh review only.
• Maintainers can also comment @clawsweeper review to request a fresh review only.
• Fresh-review commands do not start repair, autofix, rebase, CI repair, or automerge.
• Maintainer-only repair and merge flows require explicit commands such as @clawsweeper autofix, @clawsweeper automerge, @clawsweeper fix ci, or @clawsweeper address review.
• Maintainers can comment @clawsweeper explain to ask for more context, or @clawsweeper stop to stop active automation.

Shiny media proof means a screenshot, video, or linked artifact directly shows the changed behavior. Runtime, network, CSP, and security claims still need visible diagnostics.

• The egg game starts only after the PR passes the real-behavior proof check.
• Before that, no creature, rarity, or ASCII portrait is rolled. The treat waits for real proof.
• This is still just collectible flavor: proof affects review readiness, not creature quality.

Best possible solution:

Land the provider-local SecretInput auth fix after redacted real-request proof or an explicit maintainer proof override, while keeping the native endpoint fallback tracked separately and scoping release notes to auth resolution.

Do we have a high-confidence way to reproduce the issue?

Yes, at source level: current main returns arbitrary LM Studio $ENV/${ENV} string templates as literal configured keys unless they match a known marker. I did not establish a live LM Studio server reproduction in this read-only review.

Is this the best way to solve the issue?

Yes, mostly: resolving configured LM Studio apiKey strings through the standard SecretInput path is the narrow provider-owned fix, and the branch preserves header/discovery precedence. The release-note wording should stay scoped to the auth portion because the endpoint fallback remains separate.

Label justifications:

• P2: This is a normal-priority LM Studio provider auth bug fix with limited blast radius but real user impact for env-backed local inference setups.
• merge-risk: 🚨 compatibility: Merging changes exact SecretInput-shaped apiKey strings from literal bearer tokens into env-template resolution or unresolved-template errors.
• merge-risk: 🚨 auth-provider: The diff changes LM Studio API-key, header-auth, and discovery-key precedence in provider runtime/setup paths.

Full review comments:

• [P3] Clarify the linked issue scope in the changelog — CHANGELOG.md:53
  The PR body says this only addresses LM Studio auth resolution and leaves the native endpoint fallback from [Bug]: LM Studio Provider Fails: Environment Variable Expansion + API Endpoint Mismatch #80495 separate, but this changelog line says the linked report is fixed. That would overstate release scope unless maintainers intend to close the endpoint half too; use Refs or explicitly say it fixes only the env-template auth portion.

What I checked:

• Current-main bug path: On current main, resolveLmstudioConfiguredApiKey handles direct string apiKey values before the generic SecretInput resolver and returns non-marker strings literally, so arbitrary $ENV or ${ENV} templates can become bearer tokens instead of env values. (extensions/lmstudio/src/runtime.ts:84, 4af590a5f88e)
• SecretInput contract: The shared SecretInput parser recognizes exact $ENV and ${ENV} shorthands, and the public secrets docs list those forms for SecretInput fields. (src/config/types.secrets.ts:70, 4af590a5f88e)
• PR auth fix: The PR head resolves direct string LM Studio apiKey values through resolveConfiguredSecretInputString, preserves known marker handling, and allows unresolved templates only when a higher-precedence auth path is present. (extensions/lmstudio/src/runtime.ts:89, 03224c8c2734)
• PR discovery precedence: The PR head resolves LM Studio headers first, then lets unresolved configured API-key templates defer to Authorization header auth or an already resolved discovery key. (extensions/lmstudio/src/setup.ts:763, 03224c8c2734)
• Regression coverage added: The PR adds focused runtime/setup tests for unresolved env-template plus header auth and discovery-key precedence cases. (extensions/lmstudio/src/runtime.test.ts:143, 03224c8c2734)
• Maintainer review context: A reviewer noted that the missing live LM Studio request proof is acceptable from their perspective because the change is pure client-side string resolution and the targeted tests cover the relevant paths; that is useful maintainer context, but the PR still has no posted real setup artifact or explicit proof: override marker.

Likely related people:

• Peter Steinberger: Available local blame attributes the current LM Studio auth and discovery functions to commit d1fa0f9, so he is a routing candidate for current-main behavior history, with limited confidence from the local history depth. (role: current-main provenance candidate; confidence: low; commits: d1fa0f96287a; files: extensions/lmstudio/src/runtime.ts, extensions/lmstudio/src/setup.ts)
• hxy91819: They were requested for review, provided the current maintainer review context on proof/compatibility, and authored the final changelog commits on this PR branch. (role: reviewer and adjacent PR owner; confidence: medium; commits: 7ffb42c73657, 03224c8c2734; files: CHANGELOG.md)
