# 260828 cursor umbrella catalog — unit plan (wp1 docs-only)

Goal: collapse the 69-row hand-maintained cursor picker into per-base umbrella
rows (thinking merged, fast inside, 1M/Max-Mode generalized), sourced from a
single capability module informed by senpi's architecture but cleaner.

## Loop-spec

- Archetype: spec-satisfaction. Verifiers per phase: bun test <file>, tsc,
privacy scan, catalog sync output row counts. Repo-wide suite forbidden.
- References: senpi (scratch path in /tmp/senpi-scratch.txt) — capability
table/grouping/selection cited in 001; omo-ai@beta has NO cursor model map
(verified — provider-map.json is a provider-name alias list only).
- Non-goals: other providers, releases, protobuf schema changes.
- Bounds: ~10h wall; stacked PRs codex/* -> dev pre-approved, --no-verify ok,
unlimited subagents (sol + xai/grok-4.6).
- Terminal: DONE per goalplan c1-c5; NEEDS_HUMAN for user-visible id renames
beyond aliasing.

## Work-phase map

- wp1 docs (this cycle): 000-002 research + 010/020/030 decade docs.
- wp2 (010): capability core module + variant grammar + umbrella grouping.
- wp3 (020): catalog integration (discovery/registry/sync/request path).
- wp4 (030): closure — cleanliness comparison + picker proof + stack final.

# 001 — senpi/omo architecture analysis (sol-high lane, verified)

## senpi (packages/ai/src/cursor/*)

- CURSOR_MODEL_CAPABILITIES (model-capabilities.ts:81-195): 34 capability ids,
schema { evidence, window, maxWindow?, parameterOrder, defaultContext?,
requestContext?, levels: {level -> {value, encoding: parameters|variant-id}} }.
Claude order [thinking,context,effort]; GPT [context,reasoning,fast].
1M via requestContext="1m" when window>=1M.
- Variant grammar (model-capabilities.ts:204-248): strip terminal -fast; then
-thinking-<level> | -<level>-thinking | -thinking | -<level>; tokens
minimal|low|medium|high|extra-high|xhigh|max|none.
- Grouping (catalog-grouping.ts): group key = targetId + fast — FAST IS A
SEPARATE GROUP; Claude-only thinkingMode split (isClaude guard :45-47);
members with efforts collapse to one entry with thinkingLevelMap; 336-row
generated alias JSON maps live ids -> {targetId, level, legacyVariantId}.
- Wire (selection-descriptor.ts:85-120): alias-first — send catalog-served
suffix id when known (Cursor Run rejects bare capability ids with Connect
not_found, issue #1008); parameters fallback only when no alias; fast
parameter hardcoded "false" (fast reachable only via separate fast ids).
- Discovery (cursor-agent.ts:4362-4495): 1M inferred from display-name /\b1m\b/i
labels OR maxMode on /claude|gemini/ ids; reads thinkingDetails for
reasoning flag; multimodal from id pattern.

## senpi weaknesses (our targets)

1. Fast modeled twice (parameter always false + separate groups) — incoherent.
2. Claude-only thinkingMode split — separate thinking identities remain rows.
3. Truth split across static TS table + 336-row generated JSON + name regex.
4. variant-id fallback silently degrades to representative id.

## omo-ai@beta

provider-map.json contains ZERO cursor model rows (cursor only in
builtinProviderIds; 5 provider-name aliases). Cursor architecture is delegated
to its pinned senpi runtime. Nothing to adopt beyond "don't do this" —
objective's cleanliness bar vs omo is met by having any self-contained map.

# 003 — umbrella design (locks the shape both implementation phases build)

## Principles (beats senpi where it is weak)

1. ONE source of truth: a single capability module owns the variant grammar,
per-base levels, thinking/fast/1M dimensions, and wire encoding. No second
generated alias JSON (senpi weakness 3): aliases are DERIVED by the grammar,
not enumerated.
2. Thinking MERGES into the base identity for every family (no Claude-only
split — senpi weakness 2) AS A DIMENSION, not by discarding identities
(A-gate blocker 1): the capability schema carries per-variant ladders
({ regular?, thinking?, fast?, thinkingFast? } each with its own effort
list + wire order), because live ladders differ (claude-opus-5-fast
low/med/high vs thinking-fast low..max). The UMBRELLA ROW defaults to the
thinking variant when one exists (user decision: "thinking 하나로 합치고");
regular/fast/thinking-fast remain reachable via aliases that select the
variant dimension explicitly. resolveCursorSelection takes the PICKED id
(which encodes the variant via the alias) — never guesses.
3. Fast is a dimension INSIDE the umbrella (senpi weakness 1): no fast picker
rows; cursor/<base>-fast stays routable as an alias that sets fast mode on
the same umbrella identity.
4. 1M split into TWO separate capabilities (A-gate blocker 4 — window size
does NOT imply maxMode; prior probes found maxMode only on opus-fast
variants, 260822_senpi_cursor_transfer/210+310):
- window: context-window METADATA generalized per senpi's table (1M for
claude/gemini/kimi/gpt-5.6 families) — display/routing metadata only.
- maxMode (ultra rung): gated on EVIDENCE — the union of live
maxModeModels (decoded in live-models.ts:123-136, discarded by
provider-fetch today) and an explicit verified static list (currently
exactly kimi-k3, user-verified). Ultra generalizes automatically as live
evidence arrives, never from window size.
5. Back-compat absolute (A-gate blockers 2/3):
- Parser precedence: EXACT known identity/alias table first (covers
gpt-5.1-codex-max-as-base, gpt-5.5-extra, claude-4-sonnet-1m real wire
id), then cursor- prefix normalization (cursor-grok-4.5/4.6 wire forms),
then suffix grammar. A frozen fixture table pins parse+resolve for all
69 picker ids + observed prefixed/suffixed wire forms.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Preserve real wire identities before applying synthetic -1m.

Line 34 names claude-4-sonnet-1m as a real wire identity. The catalog table contains claude-4-sonnet, but not claude-4-sonnet-1m. The parser therefore treats this ID as the synthetic { baseId: "claude-4-sonnet", ultra: true } case. The resolver then composes from the base identity, so byte-equal legacy wire output is not guaranteed. Add an exact wire-identity lookup before synthetic suffix handling and pin the resolved wire ID in the compatibility fixture.

37, Update the parser and resolver flow to check exact known wire identities
before applying synthetic “-1m” suffix handling, ensuring claude-4-sonnet-1m
resolves as its literal wire ID rather than as baseId claude-4-sonnet with ultra
enabled. Add the missing exact identity to the catalog or lookup table and pin
its byte-equal resolved wire ID in the existing compatibility fixture covering
parser and resolver behavior.

- Alias retention contract: picker ROWS shrink, but the REQUEST path keeps
resolving every legacy slug (router forwards provider-qualified ids to
the adapter, router.ts:673-678; the adapter's resolver owns aliases).
A pinned session/config naming a removed slug keeps routing identically;
only fresh picker lists shrink. Tested explicitly (020).

Normalize the provider-qualified cursor/ ID before variant parsing.

The parser currently normalizes only the cursor- wire prefix. The pinned-session path uses cursor/, so legacy sessions can send the provider-qualified ID unchanged instead of the canonical wire ID.

  • devlog/_plan/260828_cursor_umbrella_catalog/020_catalog_integration.md#L54-L55: retain the pinned-session regression test after implementing that normalization.

- Quarantine is VARIANT-specific: claude-opus-5 regular stays quarantined
while thinking/fast siblings remain selectable.

## Picker shape (after)

- Rows: 4 router + ~30 base umbrellas (from 69). Efforts per row from the
default-variant ladder. Synthetic max+ultra spawn-validation appendage
(effort.ts:219-226) is a SEPARATE policy from wire ultra: effort.ts stays
in the diff (blocker 5) — synthetic max/ultra continue to be appended for
spawn validation on every reasoning row (no downstream break), while the
WIRE maps ultra to maxMode only for evidence-gated bases and clamps to the
ladder top elsewhere (exactly today's clamp behavior).
- Codex effort -> wire: suffix-id-first (Cursor rejects bare capability ids,
senpi #1008 confirmed + our own request-builder already suffix-first).
Thinking-capable base + effort E -> thinking wire id at E (family wire
order preserved from CURSOR_THINKING_FAMILIES). ultra -> base ladder top +
maxMode=true. Fast alias -> {stem}-{E}-fast.

## Module plan

- NEW src/adapters/cursor/catalog.ts: capability table (schema:
{ levels: readonly string[], thinking?: { wireOrder }, fast?: true,
bigContext?: true, window, quarantined?: true }), parseCursorVariantId
(senpi grammar: strip -fast; -thinking-<lvl> | -<lvl>-thinking | -thinking
| -<lvl> | -1m), resolveCursorSelection(baseOrAlias, codexEffort) ->
{ wireId | wireBase+params, maxMode, fast }, umbrellaCatalog() ->
picker rows. effort-map.ts becomes a thin re-export shim during wp2 and is
DELETED in wp3 once consumers move.

Use one typed contract for the catalog and its consumers.

The planning documents describe bigContext, params, and fast, but the supplied implementation exposes variants, window, maxModeVerified, canonicalId, and known. Align the documents and exported types before consumer migration.

## NEEDS_HUMAN boundary

Picker row ids stay cursor/<base> (already true for bases). Removing separate
thinking/fast/1m ROWS changes what the picker lists but not what routes —
within the user's explicit instruction, so not escalated.

Document the picker row ID boundary.

cursorUmbrellaRows() and the provider registry use bare IDs such as claude-opus-5. The routed catalog adds cursor/ through routedSlug(provider, id). State this distinction in devlog/_plan/260828_cursor_umbrella_catalog/003_design.md: the umbrella-row test should assert bare adapter IDs, while an integration test should assert the qualified picker ID cursor/claude-opus-5.

# 010 — wp2: capability core module (PR A, codex/cursor-umbrella-core -> dev)

## Changes

### 1. ADD src/adapters/cursor/catalog.ts

- export type CursorVariantKind = "regular" | "thinking" | "fast" | "thinkingFast";
- export interface CursorVariantSpec { levels: readonly string[];
order?: "thinking-then-effort" | "effort-then-thinking" | "bare";
quarantined?: boolean }
- export interface CursorCapability { variants: Partial<Record<CursorVariantKind,
CursorVariantSpec>>; defaultVariant: CursorVariantKind; window: number;
maxModeVerified?: boolean; wirePrefix?: "cursor-" }
(A-gate blocker 1: per-variant ladders — claude-opus-5 fast low/med/high
vs thinkingFast low..max representable; defaultVariant = thinking when a
thinking variant exists, else regular; quarantine per-variant — blocker 3.)
- export const CURSOR_CAPABILITIES: Record<string, CursorCapability> —
seeded 1:1 from CURSOR_MODEL_EFFORT_TIERS + CURSOR_THINKING_FAMILIES +
senpi window table; maxModeVerified only on kimi-k3 (blocker 4);
wirePrefix "cursor-" on grok-4.5/grok-4.6 regular.
- export function parseCursorVariantId(id): { baseId, kind, level?, ultra }
with STRICT precedence (blocker 2): (1) exact base-id table hit (covers
gpt-5.1-codex-max, gpt-5.5-extra, claude-4-sonnet-1m as real identities);
(2) cursor- prefix strip + re-lookup; (3) -1m synthetic suffix; (4) senpi
suffix grammar (strip -fast; -thinking-<lvl> | -<lvl>-thinking |
-thinking | -<lvl>); tokens minimal|low|medium|high|extra-high|xhigh|max|none.
- export function resolveCursorSelection(pickedId, codexEffort?):
{ wireId, maxMode, params: [] } — suffix-id-first composition reusing the
order rules currently in cursorWireModelIdWithEffort; ultra ->
top-level + maxMode when bigContext; grok fast keeps the parameter path.
- export function cursorUmbrellaRows(): { id, efforts, defaultEffort,
window, bigContext }[] — picker list derivation (router ids stay in
discovery).

### 2. Tests — ADD tests/cursor-catalog.test.ts

Named activation per branch, with a FROZEN fixture table (all 69 seed ids +
cursor- prefixed wire forms + representative live suffix ids) asserting
(parsedBase, kind, level) AND resolved wire id byte-equality against the
CURRENT cursorWireModelIdWithEffort/cursorRequestWireModelIdWithEffort
output (generated once from the old module while it still exists — the
back-compat oracle). Plus: precedence cases (gpt-5.1-codex-max stays a base;
gpt-5.5-extra + any effort -> gpt-5.5-extra-high; cursor-grok-4.6-xhigh
round-trips); thinking default variant; bare-thinking ignores effort;
per-variant ladder divergence (opus-5 fast vs thinkingFast); ultra ->
maxMode ONLY on maxModeVerified; ultra elsewhere clamps to ladder top
without maxMode; variant-specific quarantine (opus-5 regular excluded,
thinking present); unknown id passthrough.

### 3. NO consumer changes in this PR (effort-map untouched) — additive
module + tests only, so the diff reviews clean.

Gate synthetic -1m to 1M-capable bases.

The current parser accepts -1m for every known base because it checks only CURSOR_CAPABILITIES[baseId]. For example, gpt-5.4-1m and claude-4.5-opus-1m become known ultra variants even though their catalog windows are 272K and 200K. This can route unsupported model IDs. Require explicit 1M metadata, such as window === 1_000_000 or a dedicated bigContext flag, and add negative fixtures for non-1M bases.

In `@devlog/_plan/260828_cursor_umbrella_catalog/020_catalog_integration.md`
around lines 10 - 12, Update parseCursorVariantId so the synthetic -1m variant
is accepted only when the base model has explicit 1M-capable metadata, such as
window === 1_000_000 or bigContext, rather than merely appearing in
CURSOR_CAPABILITIES. Preserve the kimi-k3-1m alias and add negative fixtures
confirming non-1M bases such as gpt-5.4 and claude-4.5-opus are rejected.

- filterCursorConfiguredModelsByLiveDiscovery: match live suffix ids via
parseCursorVariantId(base match) instead of enumerated suffix compose.
- inferCursorContextWindow: read window from CURSOR_CAPABILITIES first,
fall through to current heuristics for unknown ids.

### 2. MODIFY src/codex/catalog/provider-fetch.ts (~:1276-1310) — consume
the maxModeModels ALREADY returned by live-models.ts (:123-136; decoder
needs no change, A-gate finding 6): live maxMode ids union with
maxModeVerified static flags to arm the ultra->maxMode wire rung per base.

Normalize maxModeModels before building the live evidence set. src/adapters/cursor/live-models.ts:125-136 preserves each trimmed wire modelId, while src/adapters/cursor/catalog.ts:431-448 checks liveMaxModeIds with the parsed base ID. If provider-fetch.ts unions raw suffixed or cursor--prefixed IDs, the IDs will not match and an ultra selection can send the clamped wire rung with maxMode disabled. Parse each maxModeModels ID with parseCursorVariantId, then add prefixed and suffixed max-mode fixtures in tests/cursor-hardening.test.ts; the current fixture requirement covers filtering only.

### 3. MODIFY src/providers/registry.ts (~:1092 cursor section) — model ids

### 3b. MODIFY src/codex/catalog/effort.ts (:219-226) — POLICY UNCHANGED
(A-gate blocker 5): synthetic max+ultra stay appended to every
reasoning-capable row for spawn validation. Add a comment distinguishing
catalog-synthetic ultra from wire maxMode. Regression test: spawn-validation
efforts for a cursor row WITHOUT maxModeVerified still include ultra, and
the adapter clamps it (existing clamp test extended).

### 4. MODIFY src/adapters/cursor/request-builder.ts — normalizeCursorModelId

path preserved; ultra path generalized (maxMode for any bigContext base).

### 5. DELETE src/adapters/cursor/effort-map.ts once discovery +
request-builder consume catalog.ts; migrate any residual export the tests
reference.

### 6. Tests (exact paths, A-gate blocker 7):
- MODIFY tests/cursor-effort-suffix.test.ts — wire-id oracle table from 010
stays green after consumers switch (the byte-equal back-compat proof).
- MODIFY tests/cursor-hardening.test.ts discovery sections — live filter
with suffix + cursor-prefixed fixtures via the new parser.
- ADD tests/cursor-umbrella-rows.test.ts — cursorUmbrellaRows row count
(4 router excluded; ~30 umbrellas), thinking-merged rows list their
default-variant ladder, removed slugs absent from rows but RESOLVABLE via
resolveCursorSelection (pinned-session survival unit proof), quarantined
regular excluded while thinking sibling present.
- ADD focused catalog sync test: sync output cursor section row count +
synthetic max/ultra still appended (spawn validation).
- Pinned-session integration: request with model cursor/claude-opus-5-thinking
(removed row) through request-builder resolves to same wire id as today.

Make the closure proof exact and behavior-complete.

Replace 69 -> ~34 with exact counts and define the scope of each count. State whether the expected rows include the four router entries and whether quarantined records are excluded.

Also require focused assertions for exact-identity precedence, cursor- normalization, -1m, suffix grammar, picker and legacy variant resolution, quarantine, and static/live Max Mode evidence. The request boundary in src/adapters/cursor/request-builder.ts Lines 442-484 consumes both the flattened modelId and maxMode, so row-count and legacy-wire checks alone can pass while request behavior is wrong.

As per path instructions, keep these assertions in a focused regression test near the existing tests/** subsystem tests.
