dgb(phase-b): pin sharechain bits encoding to oracle-literal goldens - #554
Merged
Conversation
FENCED Phase-B conformance KAT (no production code touched). Pins the DGB sharechain share-difficulty bits (compact FloatingInteger) field against LITERAL goldens produced by the oracle reference encoder frstrtr/p2pool-dgb-scrypt bitcoin/data.py from_target_upper_bound, at the canonical retarget anchors: MAX_TARGET -> 0x1e0fffff, MAX_TARGET/30 -> 0x1e008888, MAX_TARGET/2 -> 0x1e07ffff, MIN_TARGET -> 0x00000000. Removes the SUT-vs-SUT circularity in dgb_share_target_genesis_test (which asserts compute_share_target == target_to_bits_upper_bound of the same target) by pinning the absolute on-wire compact value. Registered in this dir CMakeLists.txt and both build.yml --target allowlists (#143). 8/8 pass.
