Verify a Charter Reliability Score

Step 1 — install the verifier

pip install git+https://github.com/RGero215/charter-spec

Or clone and install in editable mode if you want to read the rule source:

git clone https://github.com/RGero215/charter-spec
cd charter-spec
pip install -e .

Step 2 — run the 12 Charter rules

charter audit prereg.json \
    --returns returns.csv \
    --train-end 2024-09-30 \
    --output artifact.json

The CLI emits the rule artifact and a human-readable summary. Sample output:

Charter rule artifact — v17_portfolio
  Manager: Lifestyle Alpha
  Tier:    institutional

  Rule outcomes:
    R1   [PASS]  3,219 valid observations
    R2   [PASS]  Cost 1.0 bps applied to avg turnover 4.2%
    R3   [PASS]  OOS Sharpe 1.83 (95% CI [1.00, 2.04]); target ≥ 0.0
    R4   [PASS]  Alpha-Sharpe 1.31 (raw 1.47, β=0.05)
    R5   [PASS]  WF consistency 100% (4/4 folds positive)
    R6   [PASS]  Pre-reg sealed: 32bdcae7…
    R7   [PASS]  Tier: institutional
    R8   [PASS]  Max DD 3.1% vs target ≤ 15.0%
    R9   [ N/A]  Multi-seed cohort not provided — N/A
    R10  [ N/A]  Refusal log not in MVP — N/A
    R11  [ N/A]  Quarterly recert check at consumer — N/A
    R12  [PASS]  p-value 0.001 vs threshold 0.10 (institutional)

  Totals: 8 pass · 0 fail · 4 N/A
  (Submit this artifact to a Charter authority for CRS scoring.)

Step 3 — independently confirm the CRS

The rule outcomes above are the open part. The CRS scoring formula — the weights that turn the 12 booleans + summary stats into a 0-100 number — is the closed part, analogous to the FICO weighting formula. That keeps the headline score consistent across managers; the rule outcomes themselves stay verifiable to any third party.

To confirm a CRS, submit your rule artifact to a Charter authority:

curl -X POST https://audit.lifestylealpha.ai/cert/register \
    -H 'Content-Type: application/json' \
    -d '{"artifact": <your artifact.json>, "agree_terms": true}'

The authority validates the artifact's self-hash (tamper detection), applies the closed scoring formula, and returns a signed certificate with the same CRS we publish. The cert SHA-256 is then anchored to Bitcoin via OpenTimestamps for permanent public reference.
