feat(subagents): default roster to the GPT-6 trio - #5640
Conversation
Fresh configs now feature gpt-6-astra, gpt-6-sol and gpt-6-luna. A one-time version-2 step replaces a stored roster only when it still equals the previous generated default exactly; edited lists are kept. The roster migration tests move to tests/routing/subagent-roster-migration.test.ts because config.test.ts sits at its file-size cap.

📝 WalkthroughWalkthroughThe default subagent roster changes to the GPT-6 trio. A version-2 migration replaces the prior generated roster only when it remains unchanged.

Merge Risk: 🟡 Moderate · up to Users upgrading from an unversioned configuration can have a customized subagent roster silently replaced with the new GPT-6 defaults on first startup, and the change is saved. The configuration documentation also promises that reordered lists are kept, which is not true for these upgrades. Users can re-edit the roster afterward, but the migration should match the original saved list before normalizing it, and the docs should be corrected before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Update the quickstart roster alongside the default
Changing the fresh default to this trio leaves docs-site/src/content/docs/getting-started/quickstart.md:123-125 claiming that a fresh config features five GPT-5.x/Astra models; the seven translated quickstarts repeat the same stale workflow. Users following the quickstart will therefore see a different picker than documented, so update the English quickstart and its translations to name the GPT-6 trio.

Limit the preservation claim to version-1 lists.
The second step replaces only the exact version-1 generated default. Other version-1 lists, including reordered, shortened, or empty lists, remain unchanged by that step. Unversioned lists first undergo the Astra upgrade, which can change an unversioned reordered or custom list.

Identify generated defaults before normalizing unversioned rosters.
The cited four-model list was not the historical generated default. The merge-base default was ["gpt-5.5", "gpt-5.6-sol", "gpt-5.6-terra", "gpt-5.6-luna", "gpt-5.4-mini"].
The migration still loses edited choices. For example, ["gpt-5.5", "gpt-5.6-sol", "gpt-5.6-terra", "gpt-5.6-luna"] normalizes to V1_DEFAULT_SUBAGENT_MODELS, then the version-2 branch replaces it with the GPT-6 trio. The same can occur when Astra is already present in another position or when the cap removes a later entry. Startup persists this replacement.
Retain the original unversioned roster and replace it only when that original value matches a known generated default. Preserve the normalized roster for edited lists, and add regression cases for reordered, Astra-repositioned, and capped unversioned lists.

Summary
The default featured subagent roster is now the GPT-6 trio:
gpt-6-astra,gpt-6-sol,gpt-6-luna. Before this change a fresh config shippedgpt-6-astra, gpt-5.6-sol, gpt-5.6-terra, gpt-5.6-luna, gpt-5.5.Existing installs are updated once at startup by the version-2 step in
src/config/subagent-models.ts. It cleans any stored roster of retired rows:gpt-5.6-solbecomesgpt-6-solandgpt-5.6-lunabecomesgpt-6-luna, in the same position. A successor that is already listed is not added twice.gpt-5.5/gpt-5.6id is removed, includinggpt-5.6-terra,gpt-5.5, andgpt-5.5-pro./are left as written. That covers routedprovider/modelids and account-qualified<selector>/<model>choices, because a 5.x suffix there names another provider's model.For example, the previous default
[gpt-6-astra, gpt-5.6-sol, gpt-5.6-terra, gpt-5.6-luna, gpt-5.5]becomes[gpt-6-astra, gpt-6-sol, gpt-6-luna], and[gpt-5.6-sol, custom/model, gpt-5.5]becomes[gpt-6-sol, custom/model]. Unversioned legacy lists still run the Astra upgrade first. The version marker is written in every case, so later edits, including re-adding a 5.x model, are kept.Also in this PR:
