PR #TBD - #1436: Proving a Bot-Authored Live Cell

The Broader Goal at the End of the Previous PR

The identity-routing work in #1436 moved autonomous GitHub writes onto role App tokens. The remaining empirical question was whether QA could approve a PR authored by a different role bot.

Strategic Shifts in This PR (if any)

None. This is a deliberately tiny live-cell verification PR, not a product or implementation change.

What This PR Shipped

Two new documentation files: a QA note describing the test boundary and this build-diary entry. The PR itself is opened through the dev role App token and must be left open for a later QA approval dispatch.

Brainstorm Visuals Used

None. The approved design is docs/superpowers/specs/2026-09-06-workspace-agent-identity-routing-design.md.

What This Achieved on the Path to Autonomy

It supplies the missing end-to-end evidence that a dispatched implementation can create a PR under synlynk-synlynk-dev[bot], preserving the separation between autonomous work and the human GitHub identity.

Strategic Note: The Goal at the End of This PR

QA should approve this open bot-authored PR. That result closes the live-cell evidence gap identified in #1436 without merging or changing application code.
