Local main added desktop branch-from-chat, attribution headers, sidecar packaging changes, and provider model normalization. The merge keeps those mainline changes while preserving ChatGPT Official provider metadata, OpenAI OAuth runtime env, provider-load guards, and model catalog behavior.
Constraint: Current worktree was detached; created feat/chatgpt-official-oauth-provider before merging to preserve the OAuth commit line.
Rejected: Rebase the OAuth line over main | the branch already contains many reviewed commits and a merge makes the integration point explicit.

Provider-managed environments should preserve Claude attribution only when the selected model is actually Claude-prefixed. Non-Claude provider models now disable the attribution header so third-party providers do not inherit Claude-specific prompt metadata.
Constraint: Claude model detection is intentionally model-name based to match the requested provider policy.
Rejected: Remove attribution headers globally | official Claude-prefixed models should keep existing behavior.
Confidence: high
Scope-risk: moderate
Directive: Do not broaden this policy without live provider request-shape verification.
Tested: Targeted server, provider, settings, cron, and managed-env tests in prior verification pass.
Not-tested: Full verify gate after this commit.
Activating the built-in ChatGPT provider now writes a dedicated OpenAI OAuth runtime environment instead of clearing provider state. The runtime points the CLI at the desktop-managed OpenAI token file, avoids Anthropic auth/base-url variables, reports auth from the OpenAI token file, and prevents Claude OAuth injection when ChatGPT Official is active.
Constraint: Default provider sessions read cc-haha managed settings, while session-scoped provider selections inject env directly from the desktop host.
Rejected: Treat ChatGPT Official as a generic OpenAI proxy provider | proxy routing would require API-key shaped auth and would leak it into the wrong runtime path.

Teach provider presets and saved providers to carry per-model context windows so auto-compact uses provider-specific limits instead of a blanket fallback. The desktop provider form now keeps these limits in an advanced context section and syncs the generated settings preview with model changes.
Constraint: Third-party provider APIs do not consistently expose machine-readable model context windows.
Rejected: Keep a single 100K/200K fallback | modern provider windows vary from 128K to 1M+ and the fallback caused late or early compaction.
Confidence: high
Scope-risk: moderate
Directive: Do not change provider compact thresholds without re-running real provider long-context checks.
Tested: bun test src/services/compact/autoCompact.test.ts; bun test src/server/__tests__/provider-presets.test.ts src/server/__tests__/providers.test.ts src/server/__tests__/providers-real.test.ts; bun run check:server; bun run check:desktop; bun run check:policy; bun run check:native; MiniMax/Kimi/DeepSeek live long-context probes; agent-browser provider form flow.
Not-tested: quality:pr policy gate still requires explicit allow-cli-core-change for CLI core edits.
