ADDED Requirements

Requirement: RC1 default branch behavior SHALL remain unchanged

Adding shadow followthrough research SHALL NOT change RC1 default branch behavior.

Scenario: RC1 default branch regression check

• WHEN RC1 default branch is replayed on current local baseline dataset
• THEN baseline core event/trade hashes remain unchanged

Requirement: Probe branch SHALL be isolated from default governance path

The followthrough probe branch SHALL be available for observation but SHALL NOT become default governance path.

Scenario: Daily pipeline branch registration

• WHEN daily pipeline builds branch runs
• THEN probe branch appears in branch status outputs
• AND default branch remains alpha_first_glued_refined_hot_cap
• AND control branch logic remains alpha_first_selective_veto

Requirement: Probe branch SHALL use conservative subtype scope by default

Probe branch default config SHALL only enable pending queue for mid_zone_very_weak_b1.

Scenario: Probe config defaults

• WHEN alpha_first_glued_followthrough_probe_config() is loaded
• THEN glued_followthrough_pending_enabled=True
• AND glued_followthrough_allow_mid_zone_very_weak_b1=True
• AND glued_followthrough_allow_high_zone_weak_b1=False
• AND glued_followthrough_allow_ql_rebound_weak_followthrough=False
