+### ✨ New features
+
+- **Claude Code workspace template T4 tier gains host-root escalation**: the Claude Code workspace template (T4 privileged containers) now includes an additive uid-0 escalation leg, providing a wired path to host root inside the privileged container sandbox while preserving the uid-1000 agent identity and the agent-owned `/configs/.auth_token` contract. The escalation is implemented via `sudo` and `nsenter` baked into the Dockerfile. (`molecule-ai-workspace-template-claude-code` [#25](https://git.moleculesai.app/molecule-ai/molecule-ai-workspace-template-claude-code/pulls/25))
+- **Poll-mode canvas user messages now persist correctly before returning 200**: canvas chat messages sent via workspaces running in poll mode (`runtime=external`) were occasionally lost when the user exited the chat before the agent processed the message. The root cause was that `logA2AReceiveQueued` only wrote to the in-memory queue, not to durable storage. The persist call is now correctly placed before the poll-mode short-circuit, ensuring messages are durable before the canvas receives a `200`. (`molecule-core` [#1350](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1350))
+- **Inbox poller self-echo loop fixed**: when a workspace delegates a task to a target that never picks it up, the platform's `report_activity("a2a_receive")` records the activity with the sender's workspace UUID as `source_id` (per spoof-defense design). The sender's inbox poller was incorrectly processing this as an incoming message from itself — causing an infinite self-echo loop that flooded the inbox. A new `_is_self_echo_row()` predicate now skips `a2a_receive` rows where `source_id == workspace_id`, breaking the loop. (`molecule-core` [#1348](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1348))
+- **OpenClaw template adapter routing: fresh provisions now serve correctly**: OpenClaw workspace provisions were failing immediately after launch — the adapter had no routing path for the default model, causing every new workspace to be non-functional on first boot. The adapter now coerces an unroutable model to a known-good default, ensuring new OpenClaw workspaces are immediately usable without manual configuration. (`molecule-ai-workspace-template-openclaw` [#18](https://git.moleculesai.app/molecule-ai/molecule-ai-workspace-template-openclaw/pulls/18))
+- **OpenClaw template MiniMax and Kimi-For-Coding API keys routed to correct endpoints**: the OpenClaw adapter was routing all Minimax (`sk-cp-*` keys) and Kimi-For-Coding (`sk-kimi-*` keys) API calls to the wrong endpoints, causing HTTP 401 errors on every chat turn. Minimax calls now route to the Anthropic-compatible gateway; Kimi-For-Coding calls route via Moonshot's Anthropic-compat endpoint. (`molecule-ai-workspace-template-openclaw` [#14](https://git.moleculesai.app/molecule-ai/molecule-ai-workspace-template-openclaw/pulls/14), [#17](https://git.moleculesai.app/molecule-ai/molecule-ai-workspace-template-openclaw/pulls/17))
+- **OpenClaw template now shows molecule platform peers**: OpenClaw workspaces were not returning molecule platform peers in `list_peers` responses — the model was answering via its own native `sessions_list` instead of querying the molecule A2A registry. The adapter now correctly registers the molecule A2A MCP server, so `list_peers` returns platform peers as expected. (`molecule-ai-workspace-template-openclaw` [#16](https://git.moleculesai.app/molecule-ai/molecule-ai-workspace-template-openclaw/pulls/16))
+
+### 🧹 Internal
+
+- **CI/CD publish lane routing** (`molecule-core`): 7 post-merge ship jobs across 5 workflows now route to a dedicated `publish` runner lane instead of competing in the shared CI queue. Urgent production-deploy builds (e.g. P0 security fixes) no longer sit behind ordinary PR-required CI. (`molecule-core` [#1376](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1376))
+- **Runtime catalog cleanup** (`molecule-core`): `crewai`, `deepagents`, and `gemini-cli` removed from the workspace runtime catalog (internal#483). (`molecule-core` [#1385](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1385))
