Context inspection was switching from the local context estimate to the latest
provider usage total once a response completed. That provider total omitted the
assistant output tokens, even though those tokens become part of the next turn's
context, so the desktop meter could fall from 11% to 10% after work finished.
The context total now includes output tokens and keeps the local estimate as a
lower bound.
Constraint: Provider usage and local context estimates use different token accounting paths
Rejected: Trust provider input tokens alone | it omits the latest assistant output from the next-turn context
Confidence: high
Scope-risk: narrow
Directive: Context usage totals must represent the next-turn conversation context, not billing-only input tokens

Desktop users can now disable thinking for new sessions, and Anthropic-compatible providers that opt in receive explicit disabled-thinking requests across main turns, side queries, and AI title generation.
Constraint: DeepSeek/Kimi/GLM Anthropic-compatible endpoints need a non-thinking path without scattering provider-specific logic through the CLI.
Rejected: Per-model if/else branches | centralized provider preset env keeps the native CLI surface smaller and easier to audit.
Confidence: high
Scope-risk: moderate

Default desktop sessions with an active third-party provider were only passing the selected model into the CLI startup path. That allowed the child CLI to fall back to stale cc-haha settings env instead of the provider index, so the UI-selected provider could diverge from the key and endpoint used by the subprocess.
Route default sessions through the active provider id and make third-party Sonnet capability overrides explicit with a non-empty sentinel. This keeps provider runtime env sourced from providers.json and avoids treating third-party Sonnet models as first-party thinking-capable models.
Constraint: Third-party provider behavior is the product baseline for desktop users.
Rejected: Rely on synced cc-haha/settings.json env | it can be stale and caused provider/key routing mismatches.
Confidence: high
Scope-risk: narrow
Directive: Third-party desktop sessions must carry providerId into ConversationService; do not depend on global settings env for active providers.

Third-party Anthropic-compatible providers can expose Claude model names without supporting every first-party runtime capability. Desktop sessions now preserve provider-specific capability overrides, keep selected provider runtime state across reconnects and restarts, and keep the provider dialog behavior aligned with the updated presets.
Constraint: Custom ANTHROPIC_BASE_URL endpoints must not be treated as first-party Anthropic for adaptive thinking support.
Rejected: Rename provider default Sonnet models | that would hide the compatibility issue instead of fixing runtime capability detection.
Confidence: high
Scope-risk: moderate
Directive: Do not enable Claude first-party capability defaults for custom Anthropic-compatible base URLs without provider verification.
