#### Game::ServerPlayer::ComputeBudget — not checked by this run
- (high) slots 1, 2, 3, 4, 7 and 11 are produced by callees this milestone does not model (per-system output, trade, ship-carried population, a second manager, the build-queue spend) — they are copied out of the original's own output and back into the same slots, so they match BY CONSTRUCTION and prove nothing  [declared input boundary; see budget_inputs.h]
- (high) ServerSystem::ComputeOutput repairs damaged ships in orbit — replace mode runs the original a second time on a scratch Budget to harvest the six unmodelled slots, so that repair happens TWICE per turn in replace mode and nothing in the trace would show it  [guard:budget_object does not reach the ships; unverified]
- (medium) the difficulty-mods row from StrategyServer::GetDifficultyMods — not reachable from a ServerPlayer, so the two relevant entries are fitted constants measured from the B1 trace rather than snapshotted inputs
- (low) the research-allocation vector's heap block — only the element count is compared; the three words are heap pointers the default policy ignores
