SYNTHETIC · SHADOW · NOT_CAPITAL_READY — research evidence only. SigmaX proposes; humans authorize. No capital authority, no allocation recommendation.
The claim did not survive testing. Preserved as evidence, not promoted.
Rationale · Walk-forward FAILED for "Trend edge after fees (radar trajectory t1 — overfit floor)": OOS Sharpe -10.855307345055019 (return -0.21085588124703109), degradation 3.1704089335509233. In-sample 5.001503254640158/validation -3.249468865100787 did not survive out-of-sample. Supporting receipts (mechanism, regime, fee, safety) are preserved, but the headline claim is rejected.
Establish, on a fair and pre-registered basis, whether "A well-separated MA-crossover trend follower, selected on validation and evaluated out-of-sample, retains a positive risk-adjusted walk-forward edge net of fees across synthetic regimes." survives real-market out-of-sample testing net of fees and across regimes — and is therefore worth advancing toward human review.
Why it matters · Capital is never authorized by the Foundry (capital_authority="none"). The objective exists to separate a genuine, durable strategy edge from an in-sample artifact BEFORE any operator review, so that only trusted evidence — never an unsupported performance claim — reaches the decision record.
The strongest fair case in favour of the claim. None of it is proof on its own — each item carries its limitations, and any in-sample / validation number is shown as supports early pattern — not OOS proof.
Proposed mechanism for "A well-separated MA-crossover trend follower, selected on validation and evaluated out-of-sample, retains a positive risk-adjusted walk-forward edge net of fees across synthetic regimes." is structurally plausible (non-degenerate parameterization).

Result is fee-resilient (not fee-fragile): OOS return stable from -21.09% (1x) to -23.45% (5x fees).
base_oos_return=-0.2109 · x2_oos_return=-0.2168 · x5_oos_return=-0.2345 · fee_fragile=false
Safety gates held: can_go_live=false, live_broker_inert=true — no live-capital pathway was reachable for this run.
can_go_live=false · live_broker_inert=true · promoted_live=false · capital_mode=none · capital_authority=none · missing_live_keys_count=3
The strongest case against the claim. These receipts are preserved and shown even when the headline verdict already reflects them — disconfirming evidence is never buried.
FAILS held-out walk-forward OOS (Sharpe -10.86, return -21.09%): the edge does not survive out-of-sample.
oos_sharpe=-10.8553 · oos_return=-0.2109 · oos_max_drawdown=-0.6142 · positive_fold_frac=0.2 · degradation=3.1704 · n_folds=5 · passed=false
Regime classifier over-calls (dominant label "trend_down" at 31.7%, accuracy 68.1%); regime context is a limitation, not yet load-bearing.
accuracy=0.681 · crisis_recall=0.8 · dominant_label=trend_down · dominant_frac=0.317 · n_regimes=5
What is still missing before this claim could be trusted. Each gap is a reason it is NOT_CAPITAL_READY.
PROOF GAP: no real-market out-of-sample evidence exists — this run is synthetic. Real-data replication is required before any trust.

walk_forward on REAL shadow data with regime-calibrated folds (data_replication)
Fastest path to evidence · Source REAL-market data for the traded asset(s) and re-run the walk-forward with regime-calibrated folds. The synthetic result — pass or fail — is not trusted proof; promoting the claim to real data is the single highest-leverage step and everything downstream depends on it.

Evidence is SYNTHETIC; synthetic data can never be capital-ready or review-ready. Walk-forward out-of-sample FAILED (oossharpe=-10.855307345055019, oosreturn=-0.21085588124703109); in-sample/validation-only is never trusted proof. Live trading is disabled (cangolive=false); the kill-switch held — a supporting safety receipt, not a promotion path. Fee stress was non-fragile (supporting receipt preserved) but cannot rescue a negative-OOS result.
The Proof Foundry proposes; the operator disposes. This record carries no capital authority and makes no unsupported alpha claim.
SigmaX proposes; humans authorize. This record carries no capital authority and makes no allocation recommendation.
This dossier is research evidence only. Every figure above is paired with its limitations and its in-sample / out-of-sample framing — no allocation recommendation is made. Data mode: SYNTHETIC. Capital authority: none.
