OpenCode Go limits could use a stale legacy key because the probe did not read the credential database used by newer OpenCode installations.

The probe now reads the selected Go key from the database using the repository's scoped, read-only SQLite client. Selection follows OpenCode's credential ordering: active status, creation time, then ID. Database credentials take precedence over legacy auth.json and OPENCODE_API_KEY; explicit OPENCODE_AUTH_CONTENT remains an override. OPENCODE_DB is honored. External-server configurations still never use host credentials.

The existing status suite passes all 29 tests, including a real fixture database whose key wins over stale file/environment keys. Reverting the reader reproduces the failure. Provider typecheck, targeted lint, and formatting pass. After merging current main, all 29 tests and provider typecheck pass at c7cd97a, with fresh independent Opus and Sol source reviews finding no actionable defects. No real credentials or live provider account were used. Nonstandard release-channel database names require OPENCODE_DB; the existing read-only WAL sidecar constraints still apply. A downgrade to OpenCode 1.x after saving a 2.x key can leave a stale database key preferred over a newer legacy key. Console OAuth support remains separate; see #14983.

The credential-precedence change still awaits explicit maintainer approval before landing.

Original fix by @JustMarkDev in #16605. Maintainer takeover by Claude Opus 5.5 and Claude Fable 5.1 through T3 Code, independently reviewed by Claude Opus 5.5 and GPT-6.1-Sol through the Codex harness.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This production change adds SQLite credential discovery and changes which API key is used for OpenCode Go usage reporting. Because it affects authentication-sensitive data and usage/entitlement reporting, it warrants human review despite the focused scope and added test.

Walkthrough

OpenCode Go usage lookup now reads eligible API credentials from OpenCode 2’s SQLite database. Inline auth content skips that lookup. Otherwise, a stored key takes precedence over auth.json, with the environment key as a fallback.

Changes

OpenCode Go credential lookup

Layer / File(s)	Summary
Read and decode Go credentials apps/server/src/provider/openCodeUsageLimits.ts	The helper opens opencode.db read-only and looks up the newest eligible opencode-go credential. It excludes inactive rows and prefers active rows over rows with a NULL active value. It uses only nonblank decoded keys and returns no stored key on database or decode errors.
Select and verify the Go credential apps/server/src/provider/openCodeUsageLimits.ts, apps/server/src/provider/OpenCodeProvider.test.ts, docs/user/usage.md	Inline OPENCODE_AUTH_CONTENT skips the database lookup. Otherwise, a stored key takes precedence over auth.json, and OPENCODE_API_KEY remains the fallback. A test checks that an active database key is selected over competing credentials. The documentation states the local-run and Go API-key requirements and that Console-only sign-in is insufficient.

Merge Risk: ⚪ Minimal · up to 49c29

This change lets OpenCode Go usage limits work with OpenCode 2 credentials stored in its database. No actionable merge-blocking risk was identified from the supplied review context.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 29cca

The change is limited to selecting a locally stored API key for the existing usage request. External-server isolation and the request destination remain unchanged. No security vulnerability was established, but database compatibility and protection of local credential storage remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated credential flow involves the server process, the selected local OpenCode credential store, and the Go account associated with the selected bearer token. No new destination or cross-service credential propagation was established; isolation between users sharing a deployment remains unverified.

Trust Boundaries and Controls

• observed — The existing local-versus-external ownership boundary remains: disabled instances and nonempty external server URLs return before local credential access. The selected key is sent to https://opencode.ai/zen/go/v1/usage, not to the configured external server.
• inferred — The database becomes an additional trusted authority for account selection. Redirecting that authority would require control over the credential database or the environment used to resolve its location; such control was not established for an untrusted remote caller.

Resilience and Maintainability Implications

• observed — Read-only access and connection cleanup contain the lookup’s effect on OpenCode-owned credential state. Database failure does not trigger credential writes or migrations and instead permits the existing file and environment selection path.

Explanation

The description covers the problem, change, scope, verification, limitations, and related issues. However, it explicitly states that the credential-precedence change still lacks the required maintainer approval, and the reported test status conflicts with the objective summary.

Resolution

Add explicit maintainer approval for the scope and credential-precedence change, or explain why the fix qualifies for the small obvious bug exemption. Resolve the test-status inconsistency and state which tests actually ran, which failed to run, and why.

- Around line 48-50: Update the API-auth decoding helper used by decodeApiAuth
to treat a blank or whitespace-only key as Option.none(), so the
OPENCODE_API_KEY fallback remains available; preserve valid nonblank keys.
- Line 45: Update the SQL query in the credential lookup to filter for active
credentials with `active = 1` before ordering by `time_updated` and limiting to
one result. This ensures an inactive `opencode-go` credential is not selected
when falling back to `OPENCODE_API_KEY`.

hey @shivamhwp this should be an easy pr to merge, i think it drowned in the sea of other prs, if i need to drop the implementation and think of an opencode console login integration please tell me.

[juliusmarminge]

Taking over this one. I’ll reduce the tests to the useful coverage, update the implementation against current main, and verify it before publishing the changes.

[Ouna-the-Dataweaver]

@juliusmarminge one data point for this PR, from a setup where I hit the bug myself. Details are in my comment on #14983.

On OpenCode 2.0.32, the opencode-go row in opencode.db can be the expired key imported from auth.json. In that case, reading the database first still gives a 401 api_key_expired and the generic "could not read usage," as onlydole's table in #14983 shows. On the same machines (Windows and WSL), the active opencode Console OAuth access token returns 200 from zen/go/v1/usage, so the endpoint this PR already calls works with it.

If Console logins are in scope, the selection here could check the active opencode credential (OAuth or key) before opencode-go. That would cover this case and the Console API-key case from #21007 and Benglennon123's follow-up in one place.
