# STACK B — candidate overview

Version: `0.1.0-STACK-B-CANDIDATE`  
Status: `INTEGRATION CANDIDATE / NON_RUNTIME / NO_AUTHORITY_EFFECT`  
Date: `2026-08-23`

This directory contains the design-first Stack B candidate developed under
`M2M-STACK-B-01@0.5.0`.

Stack B bootstraps the directly resolved `A/T/RQ/S` polysemy of
`BCDEFGHIK` through nine carrier-aligned SARTS propositions. It preserves nine
diagonal chambers, admits categorical `SER` only under perfect carrier and
epistemic alignment, and does not execute Figura Tertia Evacuatio.

The candidate is not registered in `SYSTEM_INDEX_CURRENT.md`, is not a runtime
provider, and must not be loaded as a canonical stack or used to execute OPERA
B. External AEGIS witnesses were used only for restoration and were not copied
into this directory.
