Downloads load and verify compressed objects only when selected. Negative weights represent short exposure; no code is executed in your browser.
1. Download a complete bundle
Download the Python tool above and run this command. It checks shared objects and creates replay.zip; no repository clone is needed.
python e0543584b55263609cc8fd38cd032cb8432af6c2b48da3f53599e6e68c922f59.py https://quantarenas.com/data/evidence/runs/d6dff02244776630b953c7f5d194e58061f198a02b353b64a75a9bf51b8d4713/manifest.json --bundle replay.zip2. Replay the arithmetic
Extract replay.zip and run from its folder with Python. This verifies recorded weights, contributions and equity using only the standard library; it does not recalculate strategy decisions.
python scripts/replay_evidence.py data/evidence/runs/d6dff02244776630b953c7f5d194e58061f198a02b353b64a75a9bf51b8d4713/manifest.json3. Obtain and compare inputs
In the extracted bundle, use the recorded Python version and install the pinned dependencies. This command downloads provider inputs privately and reports inputHashMatches. Only a matching hash supports exact recomputation; revised provider data may not match. You may instead supply an original matching snapshot as private-input.json.
python -m pip install -r requirements-lock.txt

With the exact original input snapshot and recorded dependencies, run the archived strategy and walk-forward selection. Original provider inputs are not public. Revised downloads fail the input-hash match and cannot establish exact reproduction.
python scripts/recompute_evidence.py data/evidence/runs/d6dff02244776630b953c7f5d194e58061f198a02b353b64a75a9bf51b8d4713/manifest.json --input private-input.jsonAccounting assumptions
Each day's return uses the preceding day's target allocation. The new target is decided at the current close. This is a synthetic close-based model, not a measured execution price.
- Cash residual
- 1 - sum(weights); residual may exceed one or be negative for shorts/leverage.
- Decision
- Target weights use bars through close t; previous targets earn (t-1,t].
- Trading costs (bp)
- 0
- Execution assumption
- Synthetic daily target allocations, not broker orders or fills; financing/borrow costs omitted.
- Synthetic rebalance turnover
- Sum(abs(target[t] - target[t-1]*(1+assetReturn[t])/(1+grossReturn[t]))); one-way risky notional at close t after returns, divided by pre-trade equity.
- Return interval
- Sum of previous target weight times each asset close-to-close return; cash return is zero.
- Target weight change
- Sum(abs(target[t] - target[t-1])); changes in rule targets only.
- Walk-forward transition
- Candidate retains its own hypothetical state; first test return uses previous published target.

Default/pre-walk-forward history is not out-of-sample evidence. Each fold records its training and test boundaries; the selected candidate retains its own hypothetical state.

Target change measures changes in rule weights. Synthetic rebalance turnover also accounts for weight drift after returns; even unchanged targets can require rebalancing. Cash is the signed residual after net exposure.
