Tier 4 - Voice-risk review - Public pre-alpha
Consent-first voice review for supervised education.
V.O.T Guardian is a SecuredMe Education surface for teaching signal quality, consent, uncertainty, evidence gaps, and human review. It extracts acoustic variables needed for AI-versus-human review without needing to know what was said, then Tenebris purges private audio and discussion content.

Concept portal
Copy below is the factual source of truth.
Local analyzer preview
A bounded review workflow, not a verdict engine.
The current repo contains an upload review surface, acoustic feature extraction, ML predictor work, Tenebris purge logic, Twilio scaffolding, and Education pointer contracts. The landing presents these as classroom review surfaces while the app continues toward alpha.

human required
Labels stay non-accusatory: the model can support an AI-versus-human review, but the public artifact stays bounded to uncertainty, evidence gaps, and human review.
Start path
Four steps for the public pre-alpha story.
Prepare a local review
Use a supervised, consent-first classroom context. No private audio or real personal data belongs in examples.
choose audio file
Inspect signal quality
Represent visible features such as VOT, jitter, shimmer, SNR, THD, zero crossing rate, and MFCC mean.
POST /analyze
Apply Tenebris erasure
After variable capture, erase private audio and conversation content inside the Tenebris purge window.
content purge
Route to human review
Export only bounded findings for supervised interpretation. The tool supports review; it does not decide.
human review needed
Architecture boundary
Tenebris is the erasure protocol after V.O.T captures the variables it needs.
Tenebris purge protocol
Present Tenebris as the post-capture erasure layer: V.O.T keeps the acoustic variables needed for review, then purges private audio and discussion content instead of retaining what was said.
- VOT, jitter, shimmer, SNR, THD, ZCR, centroid, MFCC mean.
- Private content erased after variable capture.
- Target purge window: within 129 ms.
Twilio lane under implementation
The repo contains Twilio routes, runbooks, tests, and a live panel shape. The public page must call it a consent-first lane under implementation, not a finished live call pipeline.

Planned Cactus capsule
Cactus belongs to the planned on-device or ephemeral inference direction. It is shown as future architecture, not as already implanted in V.O.T Guardian. Its role is to help keep the sensitive context short-lived around the same Tenebris purge doctrine.
- Short-lived review context.
- Tenebris purge boundary.
- No device-wide surveillance claim.
Education contract
Pointer-only import from the Education suite.
The frontend includes a contract receiver for suite artifacts. The design shows it as a boundary panel, not a hidden data bridge.

Safety and license
Clear boundaries before the alpha coding sprint.
What it is
Defensive education, fraud-awareness learning, consent-first review, variable extraction, Tenebris erasure, and supervised evidence discussion.
What it is not
Not biometric identification, not policing, not compliance proof, not discipline, not emergency response.
Access
Keyboard focus, reduced motion, calm mode, and high-contrast utility controls are part of the public surface.
License
Secured Educational Cybersecurity License 2.0, framed for defensive education and supervised review.
