[P2] Scope Flash metadata to the Coding Plan path
src/integrations/vendors/zai.ts:48
The descriptor documents and tests this model only forhttps://api.z.ai/api/coding/paas/v4, butresolveRouteIdFromBaseUrl()falls back to classifying everyapi.z.aiURL aszai. Consequently, a general API configuration such asOPENAI_BASE_URL=https://api.z.ai/api/paas/v4plusOPENAI_MODEL=glm-5.3-flashselects this new catalog entry. The runtime then merges itsenableToolStreamingoverride and applies the Coding Plan-specific reasoning format and 1M/131k limits, even though Z.AI documents the general and Coding Plan endpoints as distinct contracts. This is new at this PR head: the host fallback existed at the merge base, but the Flash descriptor and catalog entry did not, so it could not previously activate these effects.Please address the root cause rather than only suppressing one request field: make Z.AI Coding Plan route recognition (or the application of this catalog entry's metadata) require the canonical Coding Plan path, and cover the exact Coding Plan path plus the same-host general endpoint in route, runtime-metadata, and request-shaping regression tests. The general endpoint should retain generic OpenAI-compatible behavior; this should not require a broader redesign of existing Z.AI models or unrelated custom endpoints.
UpdateScoped Z.AI GLM-5.3-Flash Coding Plan metadata to the canonical Coding Plan endpoint, including retargeted provider profiles. Addressed

[P2] Let an explicit base URL override a saved Z.AI profile's route identity
src/integrations/routeMetadata.ts:1415
The new profile guard checksactiveProfileBaseUrl ?? baseUrl, so a saved Coding Plan profile masks an explicitOPENAI_BASE_URL=https://api.z.ai/api/paas/v4. Reproduce this withactiveProfileProvider: 'zai',activeProfileBaseUrl: 'https://api.z.ai/api/coding/paas/v4', and the general URL in the environment:resolveActiveRouteIdFromEnvreturnszaiinstead ofcustom.getOpenAIModelOptionspasses that exact persisted-profile/runtime-environment combination, so/modelexposes the Coding Plan catalog—including Flash—while requests are configured for the general endpoint.Please address the root cause rather than adding another Z.AI-only exception: route identity needs to derive from the effective runtime base URL whenever one is explicitly set, with persisted profile metadata used only when no concrete runtime base is available. This is also the established behavior for ClinePass (
routeMetadata.test.ts:923-937). Add the equivalent Z.AI lifecycle regression case, and preserve normal canonical-profile restore plus generic behavior for actually retargeted routes.
Root-cause guidance
This PR is touching a cross-cutting route-identity contract, not just a catalog entry: the selected route determines which model catalog is visible, whether route-scoped limits and capabilities are applied, and which OpenAI-shim request options are eligible. The source of truth for that identity must be the endpoint that will actually receive the request. A persisted provider/profile label is useful as a fallback when no endpoint is configured; it cannot take precedence over an explicit base URL.
Please audit and fix that precedence once in the shared route-resolution path, then exercise the complete lifecycle rather than adding per-consumer patches:
- create or restore a canonical Z.AI profile;
- apply an explicit
OPENAI_BASE_URLfor both the general Z.AI path and an unrelated OpenAI-compatible endpoint; - verify active route identity,
/modeloptions and profile capability validation use the effective endpoint; - verify runtime limits and OpenAI-shim configuration use that same route identity, including the absence of Coding Plan-only
tool_streamand Flash catalog metadata off the Coding Plan endpoint; - switch back to the canonical profile and confirm its normal catalog/default behavior is unchanged.
The existing ClinePass precedence test is a useful sibling, but the fix should be validated across every profile-aware call site that supplies both environment and saved-profile context. That will prevent this boundary from being repaired in the picker while remaining inconsistent in startup, discovery, usage, or request preparation.
UpdateMade explicit runtime endpoints authoritative over saved provider profile metadata across route-sensitive behavior. Addressed

[P2] Preserve Flash limits for provider overrides
src/integrations/models/glm.ts:36
The new descriptor's 1M/131k limits are only recovered when the process environment itself resolves to the Z.AI route. For an in-process routed agent,createShimRequestcorrectly constructs the request fromproviderOverride.baseURLandproviderOverride.model, so the request reaches the Coding Plan endpoint andresolveOpenAIShimRuntimeContextcorrectly finds Flash's catalog entry.requestPreparationthen resolves runtime limits separately from the unchanged parent environment, however; that environment can still be Anthropic and does not identify the override route. The resolver returns no limits, socompressToolHistoryuses the generic 128k/32k budget and can discard tool history far earlier than Flash's advertised context window permits.Please fix the underlying split-brain route resolution rather than special-casing Flash: every request-time consumer that derives route-scoped metadata should use the same effective request identity (model, base URL, and route) as dispatch. Preserve generic limits for custom/noncanonical overrides, and add an end-to-end provider-override regression that proves canonical Z.AI Flash gets its 1M/131k limits while an otherwise identical custom override does not.
UpdateAligned provider-override runtime limits with the route selected for the outgoing request and strengthened the endpoint-boundary coverage. Addressed

…igpine#2185) DOC-ONLY + model entry partial port of upstream aceacf0 (Twigpine#2185). Skipped (per fork scope / AGENTS.md Provider Policy): - src/integrations/routeMetadata.ts (runtime interface change — conflicts with fork's `minimax-anthropic` route; requires fork-specific design decision, deferred per r3 sync convention) - src/integrations/runtimeMetadata.ts (resolvedRouteId field add + findModelDescriptorForApiName + xai/aimlapi/discoveryCache integration — multi-file runtime refactor, out of scope for DOC-ONLY path) - src/services/api/openaiShim/requestPreparation.ts (field rename) - All *.test.ts (fork Message-type drift avoidance; reasoning-effort test files depend on xhigh EFFORT_LEVELS that fork has not ported) - src/utils/providerProfiles.ts (already DOC-ONLY via r5 Twigpine#2201) - README.md (3way conflict on provider list baseline, rejected per rule #2) Files ported (5 → 7 with field parity): - .env.example (+5) — glm-5.3-flash env example - README.md — REJECTED (3way conflict) - docs/integrations/reasoning-effort.md (+63, new file) - src/integrations/brands/glm.ts (+1) — add `glm-5.3-flash` to modelIds - src/integrations/models/glm.ts (+14 → +15) — new glm-5.3-flash entry - src/integrations/vendors/zai.ts (+17/-1) — catalog entry; deletes `matchBaseUrlHosts: ['api.z.ai']` (3way auto-merged per the rule of accepting upstream's host-boundary simplification) - src/integrations/descriptors.ts (+12) — declare `runtimeMetadataScope` on ModelDescriptor for upstream parity. Runtime logic NOT ported (see below). New model: glm-5.3-flash (1M context, 131K output, vision+reasoning+coding). Fork note — runtimeMetadataScope field zombie: The `runtimeMetadataScope?: 'global' | 'catalog'` field on ModelDescriptor is declared for type-level parity with upstream Twigpine#2185, but the runtime logic that honors it (`inferredModelDescriptor?.runtimeMetadataScope === 'catalog' ? null : inferredModelDescriptor` in `resolveModelRuntimeLimits`) is NOT ported. That logic depends on upstream's `findModelDescriptorForApiName` + `resolveRouteOpenAIShimConfig` + xai/aimlapi/discoveryCache integration which is multi-file and requires fork-specific design decisions (fork lacks xai/aimlapi providers per AGENTS.md Provider Policy; discoveryCache is upstream-only infrastructure). The field is inert at runtime — fork behavior is identical to before this commit — but type-correct. Resume path: when fork runtime reconciles with upstream main (separate session), port `findModelDescriptorForApiName` and the catalog-scope branching, then add tests. Verification (5-phase): - Phase 1 build: ✓ Built opencc v0.27.0 → dist/cli.mjs rebuilt - Phase 2 typecheck: ✓ 0 errors - Phase 3 test: 5511 pass / 220 skip / 0 fail (no delta vs baseline) - Phase 4 TUI smoke: node bin/opencc -p "say 'ok' and stop" --model glm-5.3-flash → "ok" (model entry loads, CLI emits API request) - Phase 5 debug log scan: no new anomaly class (catalog + brand + vendor entries all load without warnings) Not pushed — awaiting user decision on integration into main-opencc.
