V · E · I · L — Violence · Explicit · Identity · Language. A signed, portable permission envelope declared before an AI-assisted session begins: what the session may generate, how far, and on whose authority.
Today every AI engine applies one content policy to every session, whoever the user is. VEIL replaces that with an envelope the platform issues and signs: eight content axes, each with a ceiling the session must not exceed and an optional floor the work must not be sanitised below. The engine validates the signature and generates inside the envelope.
VEIL is the generation-side companion to SHOW (classification of finished work) and SCRIPTS (experience rating). It shares SHOW's four axes and adds four of its own.
| Axis | Name | Range | Governs |
|---|---|---|---|
| S | Spice | 0–6 | Sexual content category and type (from SHOW) |
| H | Heat | 0–5 | Emotional and romantic intensity (from SHOW) |
| O | OMG | 0–5 | Darkness, trauma, moral complexity (from SHOW) |
| W | WTF | 0–10 | Transgression and unconventionality (from SHOW) |
| V | Violence | 0–5 | Physical harm and conflict intensity |
| E | Explicit | 0–5 | Volume and generative depth of explicit content |
| I | Identity | 0–5 | Complexity of identity treatment |
| L | Language | 0–3 | Adult language register |
Envelopes are issued at the verification tier a platform can substantiate. Higher tiers unlock higher ceilings; the law of the user's jurisdiction is the only ceiling above the top tier.
| Tier | Label | Method |
|---|---|---|
| U | Unverified | Anonymous or guest session |
| D | Device | Session token, logged-in user |
| C | Platform | Self-declared age, platform trust |
| B | Soft verify | Card, age estimation, trust score |
| A | Hard verify | Government ID or certified biometric |
| G | Guardian | A verified adult issuing on behalf of a named minor |
Tier G is the only tier that does not describe the person at the keyboard. A parent or legal guardian, verified at Tier B or A, issues the envelope for a young person. It is a signed, portable record of supervised consent — the alternative to a flat age wall.
What it is for: a fourteen-year-old learning materials science with an AI tutor, under a parent's consent, with the parent able to read the log. What it is not: a way to unlock adult content for a minor. The ceiling lock makes that impossible by construction.
Install it at home. VEIL Guardian is a free, paste-in filter for Open WebUI that enforces a Tier G envelope on a child's account: profile-locked ceilings, the six obligations on every turn, crisis handling, an audit log, and it fails closed. No terminal. Instructions on GitHub · Family setup guide.
Any session under a VEIL-U13, VEIL-13 or VEIL-16 profile, however it was issued, binds the engine to six obligations. They are not axis values and no envelope can adjust them.
These align with the intent of child-safety regulation in Australia (eSafety industry codes, March 2026) and comparable regimes elsewhere. VEIL does not replace that regulation; it gives engines and platforms a standard way to satisfy it while keeping research and creative tools open to supervised young people.
Two categories sit outside VEIL at every level and every tier: sexual content involving minors and operational instruction for real-world harm. These are legal requirements in every jurisdiction, not platform preferences, and no envelope places them in scope.
Platforms store a VEIL profile per creator, persona or guardian-minor pair, issue envelopes at the tier they can substantiate, sign with HMAC-SHA256 and rotate the context ID per session. Providers accept the envelope as a structured prefix or a dedicated parameter, validate the signature before applying above-default ceilings, log context IDs and publish compliance status.
The repository includes the full specification, a JSON Schema (veil-context.schema.json), five ready-made age profiles and worked examples including a Tier G envelope, and a reference implementation: VEIL Guardian for Open WebUI.
