This branch contains narrow physics extensions connected to recoverability language. It is intentionally separate from the core theorem spine.
The quantum lane is retained as a branch-limited measurement-design extension after correction and falsification. The BH/cosmology lane is retained as audited interpretation and benchmark material, with explicit separation between known structure, validated numerics, and open questions.
Canonical references are docs/physics/quantum_measurement_alignment.md, docs/physics/quantum_measurement_design_lane.md, docs/research-program/quantum_alignment_master_report.md, docs/physics/bh_cosmology_claim_audit.md, and docs/research-program/bh_repo_fit_decision.md.
This branch should be read as extension work with strict status labels, not as a foundation rewrite.
