Continue Special Functions formalization
Current block: SF-LEAN-B01. Begin with formalization/Block01/REPORT.md, CLAIM_MAP.json, declarations.json, and PROGRESS_v0.1.0.json.
The source is lean/CoupledFormal.lean. Its 29 named declarations pass compilation, axiom audit and same-kernel module replay. The unchanged 39-declaration finite projector core also passes. The compact runtime kit is restored from Lean_Compact_01.zip through Lean_Compact_05.zip, with combined SHA-256 f7548038f94ea30789ce28fc2ff769c40e9c37d8879ea133e9bea821056342c7. Do not stop merely because lean or lake is absent from PATH.
Next: connect the proved local absolute convergence to holomorphic germs and verify the termwise derivative/product identities. Then prove extension along radii R/max(q,r,a,b) for strict contractions. The existing results do not yet formalize entire continuation or Perron growth.
Run tools/verify_coupled_block.py against the stored kit and a fresh external work directory. Review receipts from every stage. Preserve this ledger and add a new immutable ledger for the next block. Do not overwrite evidence with a stronger status than the actual declaration map supports.
