feat(models): add Muse Spark 1.3 on the 1.2 spec - #3317
Conversation
Meta shipped Muse Spark 1.3 on 2026-09-02. Command Code publishes meta/muse-spark-1.3 and meta/muse-spark-1.3-contributor alongside the 1.2 pair, and OpenCode Zen serves muse-spark-1.3-contributor (Go) and muse-spark-1.3-contributor-free (Zen) on the same wire as their 1.2 siblings. Additive, not a replacement: every 1.2 and 1.1 id stays exactly where it is. 1.3 inherits the 1.2 spec on every surface that already named 1.2, because it is the same-shaped successor on the same gateway. Four surfaces move together, and three of them would have failed silently had 1.3 only been added to the first: - Effort ladder (low/medium/high/xhigh/max) for both 1.3 ids, so a client that sends an effort gets it forwarded rather than stripped. - Command Code image models, so the catalog does not advertise a multimodal model as text-only. - OpenCode Go registry: Responses wire default, the 1M context window, and text+image. Zen Go publishes no modality or window metadata, so without these declarations 1.3 regresses to the 128k default and the Codex app blocks image attachments client-side — the exact pair of defects the 1.2 entries were added to fix. - The Muse web_search guard was an equality check on the 1.2 id. Selecting 1.3 would have let Codex's search_content_types field reach a gateway that 400s it. It is now a membership set. Verification: focused bun test on the four Muse/Command Code suites (55 pass) plus bun run typecheck. The repository-wide local suite was not run at the user's instruction; CI is the full gate.

When an existing opencode-go installation already has a nonempty modelContextWindows map, captureProviderGather() calls enrichProviderFromRegistry(), whose all-or-nothing assignment in src/providers/derive.ts:481 skips the registry seed entirely. Consequently, this new 1.3 entry never reaches catalog enrichment; because Zen Go discovery supplies no window, applyProviderConfigHints() advertises the model with the unknown 128k fallback instead of 1M. Merge registry context defaults beneath user entries per model and add an upgrade-shaped regression test.

For a Command Code provider created before this release, the persisted modelReasoningEfforts map is already nonempty, so enrichProviderFromRegistry() skips all registry effort defaults at src/providers/derive.ts:493. The live 1.3 model is therefore advertised without supported reasoning levels even though the adapter recognizes the new static row, preventing catalog-driven clients from selecting the intended effort ladder. Merge the registry map beneath per-model user overrides and test both 1.3 IDs using a pre-upgrade provider config.

Use the model-specific Command Code profile URLs.
In src/providers/command-code-efforts.ts:115-119, both URLs resolve to the generic /models catalog. The refresh path therefore cannot fetch the model-specific profile. Use /models/muse-spark-1-3 and /models/muse-spark-1-3-contributor.
