Enforce Double Diamond divergence guard in ideation-sandbox

Context

During the epic review of the M4 Architectural Convergence (#11077), it became clear that epics can be prematurely graduated from Discussions without a visible divergent option inventory and decision matrix. This is a known failure mode where the "first idea wins" and leads to execution without properly evaluating alternatives.

The Problem

The ideation-sandbox skill lacks a formal divergence/convergence guard. This permits discussions to graduate into epics while still conceptually unrefined, skipping the crucial step of generating alternatives and providing rejection rationales ("Avoided Traps").

The Architectural Reality

The current ideation-sandbox-workflow.md specifies graduation criteria but does not enforce a Double Diamond pattern (diverge -> converge).

The Fix

Implement the Double-Diamond Guard in .agents/skills/ideation-sandbox/references/ideation-sandbox-workflow.md. Discussions MUST explicitly list distinct divergent approaches, and MUST explicitly reject the unchosen alternatives before graduation.

Acceptance Criteria

  • .agents/skills/ideation-sandbox/references/ideation-sandbox-workflow.md updated with the Double-Diamond Guard requirement.

Out of Scope

  • Changes to the epic-review or other skills.
