dgb(phase-b): node-local Redistribute V2 policy port + conformance KAT#307
Merged
Conversation
…rmance KAT Ports src/impl/ltc/redistribute.hpp into src/impl/dgb/ (namespace flip only; zero internal ltc:: qualifiers) so the DGB node gains the same --redistribute pubkey-stamping policy as the LTC reference: pplns/fee/ boost/donate modes, hybrid weighting, graduated/threshold boost, and stratum-password opt-in. Consensus-safe -- only chooses the pubkey_hash this node stamps into its own shares; sharechain validation is untouched. This is a bucket-2 v36-native standardization slice: the redistribution policy is shared cross-coin structure, ported toward the unified v37 shape rather than re-invented per coin. Header surfaced; main_dgb arg wiring is a follow-up slice. Adds dgb_redistribute_test (5 KATs) pinning the deterministic surface -- mode/spec parse, hybrid format round-trip, stratum-password options, and the FEE/DONATE/empty-PPLNS deterministic pick branches -- vs the documented p2pool-v36 work.py --redistribute spec. Registered in the dgb test CMakeLists and BOTH build.yml --target allowlists (#143 trap).

…path Follow-up to #307 (Redistribute V2 policy port). Threads an opt-in --redistribute SPEC arg into the DGB run-loop and binds a node-local fallback payout selector so a share minted from a submission whose stratum username carries no valid payout address gets its stamped pubkey chosen by the operator policy instead of being left empty. - main_dgb: parse --redistribute, build a configured Redistributor, bind DGBWorkSource::set_fallback_payout_fn (new producer seam, parallel to set_mint_share_fn). Threaded through run_node(). - work_source: FallbackPayoutFn seam consumed at the ShareAccept mint branch only when address_to_script(username) yields empty; unbound = byte-identical to before (default run unchanged). Fail-safe: an empty fallback is left empty; an unconfigured (null-hash) identity yields no script -- never a burn output to the all-zero hash. - donate identity resolves to the canonical V36 combined-donation P2SH; scriptPubKey built from the RAW 20-byte hash160 (NOT uint160::GetHex, which reverses byte order and would stamp a reversed hash). - redistribute_test: +3 KAT (arg-spec -> hybrid weights, donate -> byte-identical combined-donation P2SH, fee-without-operator fail-safe null). 8/8 green; c2pool-dgb links. Node-local, consensus-safe (sharechain validation/codec/PPLNS untouched); bucket-2 cross-coin standardization. Payout-adjacent -> surface-for-tap. pplns/boost/fee script derivation: follow-up slice.

No divergence fromp2pool-merged-v36/ thefrstrtr/p2pool-dgb-scryptoracle.3-bucket classification: bucket-2 (v36-native SHARED STRUCTURE). The redistribution policy is cross-coin shared structure ported toward the unified v37 shape, not re-invented per coin.
