"""OPT-11 P3: with battery modes off, is every command byte-identical to
release/1.0 7a00f12, on the paths P3 changed?

    python3 tools/opt11p3_identity.py          # prints one digest per scenario

tools/safety79_identity.py's harness (the REAL Controller on a P1 meter, so
the peak guard runs) plus a day-ahead price series and `arbitrage_enabled`,
so the site trade P3 now skips with modes on (`arbitrage.decide()`, its
claim, the sizing to the guard's headroom) runs on every cycle, with a buy
period, a sell period and periods in between, and a house that goes over the
limit. Each row hashes safety79's fields plus the trade's action, watts and
sentence. Uses only the API 7a00f12 has, so the same file runs on both trees;
test_modes_p3.py part 1 holds this tree to the digests printed on 7a00f12.
