#### Game::ServerSystem::ComputeTotalOutput — not checked by this run
- (high) the station count, as for GroupOutput — `ours` assumes zero stations, so a system with an imperial population and a station diverges by the station factor  [declared input boundary]
- (high) the slave population and its xenotech adjustment — the original's slave count is not a plain field: it runs the count through a per-species xenotech factor. `ours` takes the slave term as ZERO, so any system holding slaves diverges. The record logs the raw group-2 population sums so a divergence can be attributed  [declared input boundary]
- (medium) the capacity surplus the civilian term adds for the owner's own species — the original calls the carrying-capacity helper twice with different out-parameter slots and adds max(0, B - A) to the civilian count; `ours` uses the raw civilian population. The surplus is zero except when the colony is at its cap  [declared input boundary]
- (low) the addiction phase — `ours` assumes it is below 3, so ADDICTION_OUTPUT_MOD never applies; the record logs the system's addiction table length so the case is visible

#### Game::ServerSystem::GroupOutput — not checked by this run
- claims complete coverage: the imperial and civilian output modifiers, the 1.8 factor and the 500000 divisor are literals inside the executable, so nothing about them is assumed from the data files
- (high) the station count that scales the imperial term — the original gets it from a helper that walks the system's fleets and their ships through virtual calls and takes the system in EBX, which a hook cannot call portably. `ours` therefore assumes ZERO stations. A divergence on an imperial row is expected to be exactly the station factor, and the record carries `count` and the return, so the factor is MEASURED from the trace rather than fitted  [declared input boundary; the trace makes it recoverable]
- (medium) the slave row's output modifier, and every value the data files supply — SLAVES_OUTPUT_MOD, the two morale thresholds and their two modifiers, and STATION_BONUS_IMPERIAL_OUTPUT are read out of the live process's globals and logged with every record, so the record says which value drove it  [logged as `tuning` on every record]
