Test Shale branch-sync evidence scoping

[tabladrum]

Summary

• Adds one README marker line to create a tiny PR against an evidence-heavy base branch.
• Includes one new Shale evidence YAML generated with Shale v0.1.28.
• Verifies the fixed renderer scopes evidence to shale files in the PR diff instead of rendering inherited base-branch evidence.

Expected Shale card

The Shale card should show 1 session for this PR, not the many existing sessions already present on the base branch.

Test

• GOWORK=off go test ./...

ℹ️ Session 01KV1X0FZ2VK78YZNB0Y7GA6XN only has git fallback file evidence: Shale saw files change while the session was active, but no agent hook reported those edits. Token and command totals may be incomplete.

Intent

Verify branch-sync evidence scoping

Create a tiny test-bed PR against an evidence-heavy base branch to confirm Shale only renders evidence introduced by the PR.
