Subject: [PATCH] dgb: pin oracle SOFTFORKS_REQUIRED set (DGB-distinctive
 reservealgo+odo)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Test-only Phase-B pool/share conformance guard. Locks PoolConfig::
SOFTFORKS_REQUIRED to the oracle set in frstrtr/p2pool-dgb-scrypt
networks/digibyte.py:25 — {nversionbips,csv,segwit,reservealgo,odo,
taproot}. reservealgo and odo are DigiByte-unique; a silent add or
drop would mis-signal softfork requirements vs the oracle network.

Fenced to src/impl/dgb/test/share_test.cpp only; no shared-base,
CMake, or build.yml touch; dgb_share_test already allowlisted. No
consensus value changes (guards what already ships). 10/10 green.
