lane Y c471a5515f lane Y: the standalone's generator against lane Z's calibrated oracle pairs, and the tail's turn record
The standalone now models the turn's dominant generator cost -- 16 of a measured 18-22
words -- and lands 4 and 2 short of the two calibrated pairs, which is exactly the
per-call-site ledger's split for those turns. The state block is byte-identical; only
left differs. The answer to 'does it match the oracle' is no, by a stated amount, and
tools/rng_oracle_check.py is the instrument that says so.

The tail's last phase is modelled for the six turn-record fields recoverable from the
wire and checked against the record the game itself archived: 480 fields over 80
player-records, 0 mismatches. It stays blocked; --commit-blocked shows exactly which
five fields are missing and what they cost.

By-product, and probably worth more than the phase: the stored bankruptcy elimination
limit is injective in the maximum-income sum it is built from, so every save states the
per-system output term that blocks ComputeBudget. tools/max_income_oracle.py inverts it
-- 25 player-records over the corpus -- and recovers the protection factor as 3.3 from
the saves rather than from the data files. It also shows the engine's -0.15 divisor
disagrees with the game on 6 of those 25.

divergence unchanged: 209->204 and 108->103, 5 closed / 0 regressed on both pairs.
