v2.1.1

Baseline Usage Draft And Attention-Drift Visibility

• Added BaselineUsageDraft as a runtime-ready advisory artifact that makes baseline/context attention drift visible without claiming host-level authoritative injection proof or internal model-attention proof.
• The artifact now records required baseline refs, acknowledged-before-plan refs, cited refs, missing refs, and an advisory decision, with optional host-projected deliveredContextRefs.

Planning, Design, And Long-Task Workflow Integration

• Extended brainstorming, writing-plans, and long-task-continuation so baseline usage can be surfaced before design approval, before implementation planning, and during resumable execution slices.
• Tightened the user-visible workflow contracts so missing baseline refs can pause safely in needs-baseline-readback instead of silently allowing a plausible but under-constrained plan to continue.

Workspace Helper, Fixtures, And Scenario Coverage

• Extended scripts/aegis-workspace.py with BaselineUsageDraft schema validation, lifecycle creation support, filename inference, and the new add-baseline-usage helper command.
• Added artifact fixtures, long-task checks, workflow-quality matrix updates, and representative scenario transcript coverage so the new artifact is exercised in both contract validation and release-facing behavior checks.
