findings/subsystems/treaty-turn-stamp.md. Briefed on the post-combat tail, ranked its
phases by leaves-closed-per-effort against the standalone's 158-leaf residual, and found
that every tail phase which moves a leaf in this corpus is blocked on another lane
(ship construction, the budget) or on the tail's vtable blind spot. Section 5 lists that
ranking with the numbers. The two items below are what a lane holding no VM could close.
1. StrategyServer_StampTreatyTurns 0x007898c0, read as instructions. The diplomacy
ledger's per-turn stamp over every ordered pair of players holding a treaty, creating
the entry on demand. Sole caller is ApplyTurnCommands, so it is a HOST step and not a
tail phase. Three corrections to strategic-turn-internals.md 5.2, which is flagged in
place: the relation codes are 3=ally / 2=NAP / 1=cease-fire and not the reverse (which
combat-done-tail.md 2A already implied independently); the stamped value is Frame, not
ModCount; and the bit is the PlyrIdx field, not the player's vector position -- the
opposite convention from the shared-vision mask.
Modelled in sots-engine as host phase H02. Predicted 26 leaves on the reference pair
and 14 on pair 2 before building; measured exactly 26 and 14, 0 regressed, and +12 on
each of three further pairs from a different game at turns 2, 15 and 16 that the model
was never fitted to. 76 closed / 0 regressed over five pairs, 0 RNG words. The rule
also reproduces the ledger of ten of the eleven corpus saves entry for entry.
2. Player.Status. backlog.md item 6 has it blocked on "the writer between tail 31 and the
autosave -- watchpoint". There is no such writer. A whole-image scan for immediate
stores to ServerPlayer+0x164 finds exactly three: ProcessTurn's encounter loop writes
1, ResumePlaying writes 0 on load (the 4 -> 0 the determinism note recorded), and
StrategyServer_MarkPlayerTurnEnded 0x00821a40 writes 4 from the three End Turn
SUBMISSION paths, which run before the turn is processed. Item 6 needs one predicate,
not a watchpoint -- and an entry probe on that function names the set directly.
NOT written. The only two saves in the corpus with a non-zero Status agree with
Species != 4 on all eight players, and that is eight observations on a 1-bit predicate
that nine of the eleven saves do not exercise at all. Evaluated and reported.
Seven addresses in ghidra/addresses.d/lane-t2.json, validated to a scratch path against
the merged set (1,095 entries, no duplicate). verify/results/standalone/{report,status}
deliberately untouched: lane C3 published into them minutes before this run.
