fix(command-code): advertise reasoning efforts for muse spark - #1585
Conversation
CLI currently rejects --effort for meta/muse-spark-1.2(+contributor) with "has no adjustable reasoning effort" at the client, but the upstream /alpha/generate endpoint accepts reasoning_effort low..max (verified 2026-08-13 via direct POST with bearer from ~/.commandcode/auth.json). Previously the proxy stripped the field (via supportedCommandCodeEffort -> undefined) so effort changes had no observable effect; after this change they are forwarded and honored (reasoningTokens differentiated, max_tokens truncation behavior confirmed). ultra remains 400 as upstream validates the enum. Repro: command-code --model meta/muse-spark-1.2-contributor --effort low -p "ok" # local: blocked POST https://api.commandcode.ai/alpha/generate params.reasoning_effort=low # upstream: 200 POST via 127.0.0.1:10100/v1/responses {"reasoning":{"effort":"low"}} # before: stripped, after: forwarded

Fix missing_regression_test hygiene for 40f1394: muse spark advertises low..max but the adapter maps xhigh/ultra to the wire max. Pin that behavior so a future refresh cannot silently re-strip the field. See: direct upstream POST /alpha/generate low..max 200, ultra 400

Address CodeRabbit: xhigh is a distinct wire value for muse spark (upstream accepts it, reasoningTokens differentiated), and ultra is rejected with 400 — do not collapse them to max. Only deepseek v4 and glm-5.2 need the xhigh/ultra→max aliasing per their official profiles. Tests: pin xhigh as distinct, ultra as stripped for muse spark, and keep deepseek aliasing intact.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Limit xhigh aliasing to documented alias models.
Line 440 maps xhigh to max for any model that supports max but does not advertise xhigh. A non-DeepSeek/non-GLM provider profile can then receive max instead of having unsupported xhigh removed at line 445. This silently changes the requested reasoning level.
Require needsAlias for the xhigh branch, as already done for ultra. Add a regression case for a non-alias model with ["max"] support.
