fix(cursor): seed Muse Spark 1.3 so live discovery can surface it - #4924
Conversation
Cursor live discovery filters the configured roster instead of unioning live ids into it, so a family with no capability base stays invisible no matter what GetUsableModels returns. Six advertised muse-spark-1.3 effort variants therefore produced no Cursor row (#4820). Seed the capability base and its ladder. The ladder stops at xhigh although the roster also advertises muse-spark-1.3-max: Meta publishes no max rung for Muse Spark and an independent probe rejected it, both already recorded on META_MUSE_REASONING_EFFORTS, so publishing it would invent a capability against two sources. A request at max clamps to xhigh.

Derive this window and effort ladder from one shared capability definition instead of copying the same provider facts here, in effort-map.ts, and from META_MUSE_* in model-seeds.ts. The picker reads cursorModelEffortLadder() from the independent effort map while outbound requests use CURSOR_CAPABILITIES, so a later correction can make the advertised ladder differ from the wire selection; the repository explicitly requires provider metadata to use the canonical registry and derivation flow.

Document cursor/muse-spark-1.3, its live-discovery gating, and its minimal–xhigh ladder in docs-site/ rather than only in the maintainer-facing structure document. This row is now visible and selectable by users, while the public Cursor sections in guides/providers.md and guides/codex-app-models.md describe the bundled fallback coverage without mentioning it; update the English source and keep translated locales consistent.

Render the paragraph delimiter as \n.
The code span across lines 58-60 contains a blank line, so it renders whitespace instead of clearly showing the literal newline delimiter used by stripAntigravityRejectedClaudeSdkParagraph. Replace it with an inline code span:

Summary
Cursor live discovery cannot introduce a model family.
filterCursorConfiguredModelsByLiveDiscoveryiterates the configured roster and keeps the entries a live wire id proves available, so an id
GetUsableModelsadvertises but no capability base claims is never iterated and cannot reach thepicker. An account whose roster carried six
muse-spark-1.3effort variants therefore saw no CursorMuse row at all, while
liveModelCounts.cursorreported 223 (#4820).This seeds the missing capability base rather than relaxing the filter. The filter is deliberate:
Cursor advertises ids whose every
Runreturnsnot_found, which is whatCURSOR_KNOWN_UNCALLABLE_MODEL_IDSand the variant-level quarantine exist for, so admitting everyunmatched live id would publish models that cannot serve a request.
The ladder stops at
xhighon purpose. The roster also advertisesmuse-spark-1.3-max, butMeta publishes
minimalthroughxhighfor Muse Spark and lists nomaxrung at all, and anindependent OpenCode Zen probe of
muse-spark-1.3-contributor-freerejectedmaxwithunknown variant. Both are already recorded onMETA_MUSE_REASONING_EFFORTSinsrc/providers/registry/model-seeds.ts. A reseller advertising a wire id is not evidence the wireaccepts it, so publishing the rung would invent a capability against two contrary sources. A Codex
request at
maxclamps toxhigh; the comment names the observation that would justify adding it.Before / after for an account whose roster lists the six Muse variants:
muse-spark-1.3, ladderminimal-xhighAdding the rung also means
minimalno longer depends ongemini-3.6-flashbeing the single rowthat admits the suffix into
CANONICAL_EFFORT_SUFFIXES; that comment is updated rather than leftstale.
This does not implement the report's broader request to treat successful live discovery as the
source of available model names. That is a policy change with a real failure mode (advertised,
uncallable ids) and the maintainer triage on #4820 recommends against it as a default. #4820 should
stay open for that policy question, or be closed as the omission it reported with the policy split
into its own issue — a maintainer call, not one this PR makes.
Refs #4820.
Verification
Static only. This lane does not run the local suite, typecheck, build, install, or
ocx; a pastlocal run deleted real user data under
~/.opencodex. Evidence is source reasoning plus hosted CIon this head.
Traced instead of executed:
cursorModelDisplayNamesfilters throughisCursorBrandedLabel(/^cursor\b/i), so the unbranded "Muse Spark 1.3" is not published andcursor-display-names.test.tskeeps its "only Cursor-branded rows" invariant.cursor-catalog.test.tscomparescursorUmbrellaRows().lengthagainstObject.keys(CURSOR_CAPABILITIES).length; both sides are computed, so one more base is neutral.Its back-compat oracle iterates a frozen
LEGACY_EFFORT_IDSlist that a new base does not join.cursor-discovery.test.tsassertsids.length >= 38, which one added row keeps true.CURSOR_NO_VISION_MODELS.CURSOR_MODEL_EFFORT_TIERSare set to the same five rungs, which iswhat the catalog test's wire-id oracle requires of them.
New regression coverage, both in already-registered files:
tests/providers/cursor/cursor-discovery.test.ts— the seed row exists, the six live ids proveavailability, the row survives
filterCursorConfiguredModelsByLiveDiscovery, it carries the1,048,576 window, and it is one umbrella row rather than six effort rows.
tests/providers/cursor/cursor-effort-suffix.test.ts— the ladder isminimal-xhigh,minimalcomposesmuse-spark-1.3-minimal, and a request atmaxclamps toxhighinstead ofsending the advertised
-maxid.No live Muse inference was attempted, so this PR does not claim Cursor Muse generation succeeds. It
claims only that a family the account's roster advertises can now reach the catalog.
