Kernel v0.18.0 · TUI/Portal v0.11.5

New features and improvements

1. 01

   Native Windows kernel adapters and process lifecycle

   The kernel now wires native Windows adapters and lifecycle/process support behind contracts and platform selectors, closing a capability gap without leaking platform mechanisms into core contracts.

   • Windows kernel runtime adapters and process handling land across the reviewed capability DAG (src/lingtai/adapters/windows/, src/lingtai/tools/daemon/windows_process.py, PR #988).
   • A dedicated Windows PR workflow (.github/workflows/kernel-windows-pr.yml) checks the platform surface on every change.

   Why it matters:Windows support is now testable and enforced per change, not a manual afterthought.

2. 02

   Native multi-account Codex pooling and quota handling

   Codex account pooling moves to native multi-account selection with quota visibility, zero-quota exclusion, context-scoped epochs, and service-tier propagation.

   • Accounts with zero quota are skipped automatically instead of being retried (src/lingtai/auth/codex_pool.py, #990).
   • Multi-account selection, epoch binding, and epoch scoping are native and context-aware (src/lingtai/auth/codex_account_source.py, #1003–#1005).
   • Native quota-auth materialization closes out the pooling work (src/lingtai/llm/openai/codex_quota.py, #1006).

   Why it matters:Fewer wasted retries and clearer per-context quota boundaries make multi-account Codex usage more predictable.

3. 03

   Outlook OAuth2 IMAP and more resilient Telegram updates

   Mail and messaging integrations gain a new OAuth2 IMAP provider and preserve inbound Telegram data through lossless updates and task-card self-healing.

   • Personal Outlook accounts can connect over OAuth2 IMAP, kept minimal and scoped (src/lingtai/mcp_servers/imap/, #991–#992).
   • Telegram inbound Bot API updates are preserved losslessly, and non-deletable task cards recover automatically (src/lingtai/mcp_servers/telegram/updates.py, task_card/, #984, #1000).
   • The daemon completion MCP now survives external-CLI config rehydration (#985), and compact-countdown recovery is enforced (#1007).

   Why it matters:Messaging and mail integrations stay correct and recoverable under real-world failure and reconnection.

4. 04

   A supported, verifiable Windows install path for TUI/Portal

   TUI/Portal keeps source release and Homebrew source-build support, and adds one bounded native Windows path with an explicit verification contract.

   • The tag workflow publishes lingtai-<tag>-windows-amd64.zip, its .sha256 sidecar, and lingtai-bundle-manifest.json (.github/workflows/release.yml, PR #699).
   • install.ps1 validates the exact tag, AMD64 archive, checksum, bundle pin, and pinned kernel wheel before installing (install.ps1, kernel-release.json).
   • PowerShell 5.1 and 7+ contract coverage is recorded in scripts/test-install-ps1.ps1 and windows-installer-smoke.yml.

   Why it matters:Windows users get a verifiable path without weakening the guarantees the source and Homebrew paths already provide.
