Build a Delegated Voice Agent Consent Envelope and Action Auditor — implementation

## Build
Audit voice assistant commerce transaction transcripts against machine-readable consent envelopes. Detect prompt injection, unauthorized order confirmations, and budget exceedances before dispatching Beckn network order calls.

## User
Consumer digital rights advocate

## Workflow
1. Parse audio-transcribed user utterances and extract intended commerce intents, item quantities, and spend limits.
2. Compare extracted purchase intentions against user-defined consent receipts specifying allowable autonomous actions.
3. Identify discrepancies such as unintended cross-selling items or unconfirmed high-value items.
4. Compile an auditable transaction approval or denial slip with explanatory violation tags for user review.

## Interface
Voice transcript reviewer displaying conversational turns, detected intent slots, consent boundaries, and verdict.

## Data
Synthesize realistic vernacular-to-English voice commerce transcripts with deliberate edge-case policy violations.
Starter examples below are synthetic. They are not downloaded records.

## Source
[Beckn protocol specifications](https://raw.githubusercontent.com/beckn/protocol-specifications/master/README.md)
Uses Beckn protocol transaction ordering stages (discovery, ordering quote agreement, confirmation) to define consent scopes.

## Tools
mastra-ai, pydantic, pytest.
Mastra AI provides transparent agent workflow coordination and verifiable step logging for auditability.
Instruction-tuned model with strict intent classification and parameter extraction capabilities.

## Deliverables
Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

## Acceptance
- Detects discrepancies between spoken quantity and cart items prepared by the delegated voice agent.
- Blocks transactions when extracted order total exceeds the pre-authorized single-transaction budget limit.
- Produces structured audit envelopes containing validation results for human user sign-off.

## Safety
Inspects simulated voice commerce logs only; does not place live orders or access real payment gateways.
Use mock external writes. Require human review before any real deployment.
