# ADD-ON Dual-Modality Profile — OPERA Q MNEMONICA

Version: 1.0.0

Status: ACTIVE ADD-ON PROFILE

Add-On ID: `ADD_ON_OPERA_Q_MNEMONICA`

## Principal-stack composition

- Lifecycle: AVAILABLE / OPTIONAL SIGMA_SATOR COMPONENT.
- Entry: the active bundle selects Q MNEMONICA; vanilla Q/T and root-class
  constraints remain authoritative before local admission and execution.
- Capabilities: mnemonic Q execution, Palatium structures, room artifacts, and
  declared runtime refinements.
- Dependencies: local index, Q MNEMONICA class family, Palatium ROTAS support,
  vanilla root laws, and the selected SIGMA_SATOR kernel.
- Validation: local-index closure and generated kernel/source hashes must pass.
- Failure posture: unresolved carrier, missing room/support artifact, or failed
  AREPO gate blocks execution without mutating the principal stack.

## Standalone packaging/deployment

- Lifecycle: AVAILABLE / OPTIONAL DEPLOYMENT COMPONENT.
- Package: `../JSON_STANDALONE/ADD_ON_OPERA_Q_MNEMONICA_STANDALONE.json`.
- Entry: load the embedded root laws, local index, class family, and
  `00_SIGMA_SATOR_Q_MNEMONICA/SIGMA_SATOR_Q_MNEMONICA_KERNEL.md`.
- Capabilities: the packaged Q MNEMONICA scope only.
- Validation: generated kernel validity, complete source manifest, byte counts,
  and SHA-256 values must pass.
- Failure posture: fail closed on missing/stale artifacts or invalid kernel;
  standalone mode never becomes implicit vanilla authority.
