# Task summary

Execute saved-agent jobs through the existing runtime-agnostic harness and normalize progress, tool, approval, failure, cancellation, and completion events for downstream consumers.

## Description

A durable job supplies a pinned agent version and requested role or capability. The worker loads that definition, resolves model policy through `ResolvedModel`, selects an execution harness adapter, and emits a normalized event stream such as `run.started`, `text.delta`, `tool.requested`, `approval.required`, `run.failed`, and `run.completed`. OmniRoute remains an inference gateway reachable through provider resolution; it is not the harness. This task owns runtime execution, normalized persisted run/tool/approval events, and recoverable checkpoints; it does not project events into chat, persist the final chat message, or create notifications.

## Subtasks

- [ ] Define or extend the harness contract for normalized asynchronous run events.
- [ ] Adapt the current OpenCode worker runtime and model-routing flow without chat-specific provider branches.
- [ ] Persist normalized run/tool/approval events and recoverable checkpoints behind a consumer-neutral interface.
- [ ] Add cancellation, approval, tool authorization, adapter parity, and failure-recovery tests.

## Owner or assignee

`unassigned`

## Status

`ready`

## Estimation

`L`

## Acceptance criteria

- [ ] Harness context assembly and each tool call revalidate context/grant/lifecycle authority; same workspace, prior approval or model-requested access cannot bypass private-object restrictions.

- [ ] Chat code contains no direct OmniRoute, Anthropic, OpenAI, Google, or Vercel-specific branch.
- [ ] The same chat job can run through different harness adapters using one event contract.
- [ ] Normalized run/tool/approval events and checkpoints are durable and workspace-scoped.
- [ ] Browser connectivity is not part of harness execution and cannot cancel a run implicitly.
- [ ] Chat projection, final chat-message persistence, and notifications remain exclusively owned by `Task-agent-chat-run-delivery.md`.
- [ ] `pnpm lint && pnpm type-check && pnpm test` pass; `pnpm build` passes for worker changes.
