chore(bayn): record candidate 6 development rejection by gregkonush · Pull Request #13352 · proompteng/lab

gregkonush · 2026-07-28T09:43:09Z

Summary

remove Candidate 6 from the Bayn strategy runtime and public exports after corrected development evidence failed the economic advancement gate
retain one authoritative, Schema-decoded, canonical-hash-verified rejection receipt; remove the duplicated preregistration JSON, preregistration Markdown, generated development report, and all production/research strategy implementation
record the corrected close-time bounded-notional execution semantics and conventional non-wrapping moving-block bootstrap evaluated in commit 8306797e1666c6a999899eb8ecebe4fdf2184600
preserve that evaluated revision in Git history with corrected source, regression tests, and byte-identically regenerable report/preregistration artifacts; the final tree removes them after binding the rejection receipt to that commit
keep the 2023-01-03 through 2025-12-31 holdout untouched; no official Candidate 6 trial, broker mutation, or capital authority was enabled

Corrected development evidence

Bounded development data only: 2016-01-04 through 2022-12-30.

net annualized return: 0.013615189649529347
net annualized volatility: 0.02487268900470754
net Sharpe: 0.5561433659477207
SPY buy-and-hold Sharpe: 0.6386425320738072
maximum drawdown: 0.03187724596205377
annual turnover: 2.6140928678079276
95% annualized-return interval: [-0.0010095656992797435, 0.03036320620238341]
95% Sharpe interval: [-0.02703043492393884, 1.214213314331432]

Both intervals cross zero, and Candidate 6 does not exceed the SPY development benchmark. Disposition: HOLD_REJECT; recommendation: close without merge.

Final diff

Only three files remain relative to main:

services/bayn/candidates/ordinal-6-month-end-liquidity-reversal-rejection.json
services/bayn/src/candidate-research-receipt.ts
services/bayn/src/candidate-research-receipt.test.ts

Validation

focused Candidate 6 corrected implementation suite before rejection: 48 pass, 0 fail
final Bayn suite: 834 pass, 122 intentionally skipped integration cases, 0 fail
TypeScript: pass
Effect diagnostics: pass
Oxlint and type-aware Oxlint: pass
Oxfmt: pass

canonical receipt drift and excess-property verification: pass
evaluated revision report/preregistration regeneration and byte comparison: pass
receipt-to-evaluated-commit report SHA, report hash, executable behavior hash, strategy hash, and preregistration hash comparison: pass
git diff --check: pass

Breaking Changes

Candidate 6 is not retained as a production strategy. No existing selected strategy or runtime composition changes.

Closed without merge: Candidate 6 is terminal HOLD_REJECT; rejected research artifacts and generic receipt machinery do not belong on main.
