opencode-go/* threads fail on the first message with Variant unavailable: medium. inferDefaultVariant() doesn't know the opencode-go provider, so Go models get no default, and a saved or inherited variant (medium, xhigh) is sent even when the model only offers low/high/max.
modelVariants.ts and use it from status.ts for both capability versions. Go models prefer max, then high, then medium, then the first advertised variant. OpenAI and Zen defaults are unchanged.Fixes #15645 (triaged bug).
status.test.ts and OpenCode2AdapterV2.test.ts: 8 fail without the fix, all pass with the fix.vp run check:changed: format, lint, knip and typechecks pass; 107 tests pass.low/high/max with a stale medium selection now sends max and the turn completes.Code by gpt-6.1-sol (xhigh) in Codex CLI.

Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — This change adds OpenCode Go default-variant selection and rewrites unsupported saved or inherited variants before production thread creation or turns. It changes user-visible product defaults and runtime model-selection behavior, so the impact should be reviewed by a human.

The change adds provider-specific variant defaults and uses directory-specific model catalogs to resolve OpenCode 2 model selections. The catalogs store context windows and supported variant IDs. Tests cover model switches, worker sessions, concurrent reads, failed-read retries, and resume behavior.

|---|---|
Provider-specific default inference packages/provider-opencode/src/server/modelVariants.ts, packages/provider-opencode/src/server/status.ts, packages/provider-opencode/src/server/status.test.ts | The shared inferDefaultVariant function selects defaults based on provider and available variants. status.ts uses the shared function. Tests check defaults and option ordering across OpenCode versions 1.14.19 and 2.0.20. |
Directory-aware variant resolution packages/provider-opencode/src/server/v2/adapter.ts, apps/server/src/orchestration-v2/Adapters/OpenCode2AdapterV2.test.ts | The adapter stores context windows and variant IDs in per-directory catalogs. It retains listed variants and infers a default when a selected variant is unsupported. Thread creation and turn startup use the thread directory. Tests cover model switches, worker-session selections, concurrent catalog reads, failed-read retries, and resume without a runtime policy. |

Explanation
Issue [#15645] requires supported defaults for opencode-go models and validation of saved or inherited variants. inferDefaultVariant selects max, high, medium, then the first advertised variant for opencode-go. status.ts uses the helper for both capability versions. The OpenCode 2 adapter caches advertised variants by directory, preserves supported selections, and replaces unsupported selections with an available default. The tests cover stale medium and xhigh, missing selections, worker inheritance, resumed threads, and failed catalog reads.
Explanation
The changed default helper, status integration, model catalog cache, adapter validation, concurrency handling, retry handling, and tests directly support issue [#15645]. The reviewed diff shows no unrelated product behavior.

The description covers the problem, change, scope, and verification. It links the triaged issue and reports test results and an untested scenario. It does not include an explicit maintainer approval comment or explain why the fix qualifies for an exception, but the description is otherwise mostly complete.

Preserved @vkpdeveloper's commits and merged current main. The shared default helper and per-directory validation were the right boundaries, so those remain. Added the missing catalog read for turns resumed without a runtime policy, and used parsed model IDs for catalog lookup so padded saved slugs cannot bypass validation. Shortened comments; no product behavior was dropped.
Verification on 1a901a492a12ad1782a859476420c88799b75844:
vp run check:changed passed: format, lint, both knip passes, GraphQL, five affected package typechecks, and 135 tests. The restored-thread and padded-slug regression failed before each fix. No new test files.medium and the turn failed with Variant unavailable for opencode/deepseek-v4.1-flash-free: medium; the final change selected advertised high and the turn completed.Known low limit: the pre-existing readModels closure has no dedicated named Effect span. The final bot review raised this tracing-only nit; deferred to keep the variant fix focused.
Unverified: authenticated opencode-go inference, native desktop/mobile, and remote/tunnel clients. @vkpdeveloper, this VM has no Go credentials or Go catalog entries; live inference used the free model with the same low/high/max variant set. Go defaults and worker inheritance were verified by replay, not a Go account.
Before: main 9d7997afc5, same prompt, response and controls. Chat crop excludes unrelated sidebar state.
before: main web client with DeepSeek High and completed OK response
After: 1a901a492a, matching data and chat crop.
after: final web client with DeepSeek High and completed OK response
Full-window recordings show submission through completion. Sidebar history differs between runs; uploaded playback and seeking were checked. GitCafe currently renders these external uploads as links; the media itself renders and plays correctly in Chrome.

Verified unchanged head 1a901a492a12ad1782a859476420c88799b75844 against github/main at c3858bf1f7 on this Linux Boat VM. Installed dependencies in both checkouts and ran one background dev server at a time. Created a real project and threads through the app. Used repository Playwright with /usr/bin/google-chrome, real Codex gpt-6.1-sol, and real OpenCode 2.1.4. No mocks, fixtures, or replay provider.
The web picker already normalizes selections. I submitted the stale selection through the running server's normal orchestration.launchThread WebSocket API to reach the changed adapter boundary. Both requests used the same prompt and live opencode/deepseek-v4.1-flash-free model, advertising low/high/max:
| 1 | main: requested variant=medium |
| 2 | native variant=medium |
| 3 | run=failed |
| 4 | Variant unavailable for opencode/deepseek-v4.1-flash-free: medium |
| 5 | pr: requested variant=medium |
| 6 | native variant=high |
| 7 | run=completed; assistant=VERIFY_OK; errors=[] |
Native selections and terminal states were read back through orchestration.getThreadProjection. This verifies the shared adapter repair against a real provider. For this Zen model the preserved default is high; it does not prove Go's max default with an authenticated Go account.
Neighbor checks: explicitly selected low remained low and completed from the web composer. Two further web-submitted messages in that same thread returned NEIGHBOR_OK and FOLLOWUP_OK. Codex gpt-6.1-sol completed web-submitted turns on main and the PR. The recording shows a follow-up submission and live response with Low retained.
Blacksmith: vp test run packages/provider-opencode/src/server/status.test.ts apps/server/src/orchestration-v2/Adapters/OpenCode2AdapterV2.test.ts passed all 135 tests. GitCafe reports 28 successful head checks, zero pending or failing. No source changes or pushes were needed.
Before and after use the same prompt, model and project; sidebar history differs. Inspected the full-size captures and exported recording. Uploaded video playback and seeking work in Chrome. Reopened the posted comment: GitCafe renders these external uploads as links rather than inline media; the uploaded assets themselves load and play correctly.
main: stale medium fails through the live OpenCode 2 adapter
pr: the same stale medium request resolves to high and returns VERIFY_OK
pr: real web follow-up submission completes with the selected Low variant preserved
Authenticated opencode-go inference and its max default: this VM has no Go credentials or Go catalog entries. Live inference exercised the same adapter validation using a free Zen model; Go default ordering and inherited worker cases passed the existing tests only. Live worker inheritance, native desktop/iOS/Android, remote/tunnel clients, and macOS/Windows were not exercised.
Two temporary browser harness attempts timed out while loading a new thread or awaiting an RPC; direct navigation and real web submission subsequently worked. No provider turn stalled for ten minutes. Initial root startup briefly selected the default ~/.t3; I stopped it and restarted with an explicit task-only home before PR scenario verification. Main and PR verification used isolated task state.
