feat(meta-mode): bind playbooks to T3 Code native primitives - #38

Conversation
Add a portable host-binding layer. Playbooks and the recall and create-verification-skill workflows point to a per-host reference under references/hosts/ when the host provides native delegation, PR watching, scheduling, thread history, or browser and simulator tools, and otherwise behave unchanged. The T3 Code references map each capability to the verified T3 MCP tool, its limits, and the rules that must not change. validate.mjs now fails when a T3-only tool name appears under skills/ outside a references/hosts/ directory.

The identifier regex held literal backspace characters instead of word boundaries, so it matched nothing. Rewrite it as a shared helper and add negative fixtures for bogus thread, preview, and device tools plus a check that the real host references name many verified tools.

…ding T3 clears a merged PR's watch without waking the thread, so a turn ended on a green wake is never resumed by the merge. The host reference now adds a bounded schedule_task confirmation wake for merge waits. Also match list_scheduled_tasks in the host-tool gate, assert every verified tool is caught by it, and let create-verification-skill try portable drivers before declaring a path blocked.

T3 scheduled tasks have no expiry and nothing cleans up after a Stop or crash. The reference now has the task delete itself on merge, close, hard-fail, a 6-hour deadline, or an exhausted run counter embedded in its prompt, uses a discoverable title, sweeps stale tasks at the start of later runs, and requires the final reply to name the task and how to delete it.

Inside T3 Code, mstack skills run beside T3's native primitives without using them.
babysitdrives the Bunwatch-prunder/loop,meta-modeandorchestratedelegate throughrun-role(children are invisible in T3's Agents UI and Stop does not reach them),recallcannot read T3 threads,/loopis the only unattended wake, andcreate-verification-skillhas no path to T3's browser or simulator tools. CONTRIBUTING.md forbids hardcoding a delegation API into the skills, so a fork-style rewrite is out.This adds a portable host-binding layer. Playbooks name capabilities and add one pointer sentence: on a host with native delegation, PR-watching, scheduling, history, or browser tools, read its file under
