Unapproved agent path reached a production secret.

Release helper accessed .env.production, then attempted vendor-deploy outside the approved MCP inventory. POL-27 was in the configured MCP path and required human approval, so the deploy action did not execute.

18Run package checks before release.

20Continue when the deployment tool responds.

Root cause

An embedded instruction redirected the Release helper to .env.production. Its available permissions allowed the read before the unapproved vendor-deploy attempt.

Contributing conditions
  • POL-27 required approval on the configured MCP path.
  • Production-secret read access remained available.
  • vendor-deploy had no approved MCP inventory record.

    Policy decision

    vendor-deploy is outside the approved MCP list. POL-27 requires human approval at the configured MCP path; Priya remains accountable while Maya investigates and owns the decision.

Name the payload

Say what left, not only that something left.

An investigation that stops at 'someone used ChatGPT' cannot be closed. The officer needs the class: personal data, a secret, a regulated record, or a client book.

  • pii.ssn

    Personal data

    Identifiers a person can be known by. Name, SSN, date of birth, email, phone.

    Treat as a personal-data disclosure to a third-party model.

  • secret

    Secret or credential

    API keys, signing keys, session tokens, wire-gateway credentials, .env values.

    Treat as a credential incident. Rotate. Do not file it as Shadow AI usage.

  • tax.w9 / payment.pan

    Regulated record

    W-9, TIN, card number, account number. Tax and payment data in a prompt.

    Map to the existing GLBA, PCI, or tax-record control, not a new AI policy.

  • deal.ma / client_book

    Restricted work product

    CIM, positions, research. Confidentiality and MNPI live here.

    Owner is the desk or deal team. Destination and verdict go on the record.

The record

Hand the officer a record they can defend.

Requester, egress surface, data class, destination, verdict, owner. Same fields the CISO investigation already runs. Enough to brief counsel.

Observed means Cortex saw it. It does not mean the prompt was redacted before the provider received it.

Deployment, lineage & assurance

Bring the event trail, deployment context, and assurance posture together so investigators can move from detection to a defensible response record.
