TradeManager::Slot13RngCalleeA, entered 0 times in every measurement any lane
had taken, is entered 1x/turn once a player fleet is parked on a trade-sector
node, and OnAllCombatDone_Tail's RNG word delta goes 0 -> 1. Lane W3's open
risk is realised, not retired: the RNG ledger and the standalone's generator
model need extending by one draw site.
The gate is neither freighters nor a deployed spy. It is a fleet whose LocID
resolves to a node of kind 2 (TradeSector), positioned bit-equal to the
sector, whose owner's bit is set in the sector's tscr mask -- which the
CCC_ComRaid tech sets, taking tscr from 252 to 253 and setting ServerPlayer
CnRad. Before the tech the game refuses in as many words: 'Alpha Fleet cannot
raid trade sector.'
Control: same guest, same build, same shim.cfg.l3probe, one End Turn on lane
L3's turn-15 save -> all three inner callees 0, tail delta 0. Guest adoption:
ref-turn2 hooks=off reproduces the published determinism oracle exactly.
Corrects lane L3 §3.5 (the turn-15 save already had a freighter in service --
the AI's -- so 'freighters' was falsified before this lane started) and lane
V2's 'trade slot 13 is draw-free'. The spy half is decoded but NOT reached:
no AI system in that game has an asteroid belt, so a deploy was impossible,
and spies2 is therefore still untested and stays a rule-6 hypothesis.
Two new corpus saves; expect the coverage ratchet to break on CnRad,
tscr=253, three rt records and a fleet whose LocID is a TradeSector.
