Owner decisions: research only (live scans stay on the CPU code), gpu_backtest.py stays the base reference, every research flag supported, the one exemption from instructions item 6 recorded in backtest/instructions_for_backtest.txt. - backtest/cuda_signal_kernels.py: the CUDA decision stage. K1 = engine.py + the GPUTechnicalEngine overrides (one thread per bar), K2 = analyze_from_dataframes end to end incl. gates 6b-6i, the four setup generators and the regime filter (one thread per primary bar), K3 = position_sizing.build_features, K4 cooldown, K5 prefix median, K6 recorder bar rows. Config packer with generated #defines; leaf module; --fmad=false; Python evaluation order kept (ternary min/max, pairwise sums, Neumaier sum(), exact round(x, 2)). - backtest/cudaBasedBacktesting.py: same CLI, cache files and writers as the reference; the host turns kernel codes into the exact strings; no CPU path. - test_all.py Module 37 (16 tests): every stage pinned against the live code; suite 552 / 552 on the GPU, without CUDA and with FB2_BACKEND=cpu. - Proof: five reference MD5s, four 6-month acceptance books (M5/M15, $0.65/$0.30), M15 OOS --export-features and --record --record-bars tables, ten research-flag variants, and the owner's five-year M5 and M15 books, all byte-identical to gpu_backtest.py. Wall time 0.8-6.6 s per book against 13-353 s. - CLAUDE.md sections 1, 3, 6, 7, 9, 10, 11 and the instructions addendum: any signal change is now a parity event for the twin.

M5 five-year book on the CUDA research twin — 2026-09-18
Owner request, the companion of m15_5yr_cuda_2026-09-18.md: a five-year M5 backtest with
backtest/cudaBasedBacktesting.py. Same owner-requested exception to the three-year cap
(CLAUDE.md rule 1), same status: a read-out of the shipped configuration on a longer window,
nothing tuned, nothing ships.

Against rule 1 for the record: the five-year window fails it (first half negative), on a first half of only 129 trades. The shipped M5 configuration was validated on 2024-09-05 → 2026-09-05 (+146.1R, PF 1.52, 781 trades) and the 12-month window (+108.8R, PF 1.54).

Two things the M15 window did not show as sharply:
- M5 barely trades before 2025. 225 trades in the first 3.4 years against 680 in the last
1.6. Trade generation on M5 is governed by dollar-denominated floors: target 1 must clear
30 × $0.30 = $9 (
SPREAD GATE), the generic and chart-pattern stops are floored at $8, and a chart pattern needs a $9 height. At 2021–2023 prices and volatility an M5 ATR of $1.5–3 puts a 1.5 × ATR target far below the floor, so the spread gate vetoed almost every setup and only high-volatility bursts survived. The pre-2025 M5 book is therefore a burst-only sample, not the shipped strategy under normal conditions. - One quarter carries the window. 2026-Q1 made +90.2R of the +127.1R total (71%); 2025 Q1–Q2 another +32.3R. Quarterly R outside those three quarters ranges −6.5 … +5.8. This is the fat-right-tail shape of every M5 reading (cycle 1: the top 5% of trades = 94–96% of R; here the top 5%, 45 trades, carry +145.8R of +127.1R) compounded by a single very favourable quarter.

3. What to do with this
Nothing ships. Two honest readings for the owner:
- The five-year M5 figure (+127R) is not "five years of edge"; it is the validated 2024-09 → 2026-09 book plus three and a half years in which the dollar floors kept M5 almost out of the market and the few trades that got through lost a little. The three-year cap already keeps decisions inside the period where the gates behave as designed.
- The concentration in 2026-Q1 (71% of the window's R) is a fact about the shipped M5 edge, not about the window length. It is consistent with every earlier M5 reading and is the reason the advisory outcomes over a quiet fortnight can look nothing like the book.
If the owner wants the floor effect measured rather than inferred, a --record --record-bars
run of this window on the twin (seconds) with a by-year count of SPREAD GATE and LOW ATR FILTER warnings per analysed bar would settle it. Changing the floors is a rule-1 event in its
own right (round_trip_cost drives the live target floor, CLAUDE.md rule 1) and is not proposed.
