# Product Boundary and Release Authority Decision
|
||
|
||
- **Status:** Accepted
|
||
- **Date:** 2026-08-20
|
||
- **Scope:** Photo-assisted bowel logging and release governance
|
||
|
||
## Context
|
||
|
||
Timmy can make a conservative visual suggestion from a user-selected image, but the available general-purpose model is not clinically validated. The product must preserve manual logging, deterministic red-flag escalation, and user control regardless of model availability or output.
|
||
|
||
## Decision
|
||
|
||
### Observable AI fields
|
||
|
||
AI may suggest only:
|
||
|
||
- visible Bristol form (Types 1–7);
|
||
- broad color;
|
||
- image quality.
|
||
|
||
Every suggestion is provisional, may abstain, and requires user review or correction before it can enter the journal. Symptoms remain user-entered, and journal saving is separate from training contribution consent.
|
||
|
||
### Prohibited inferences
|
||
|
||
AI must not infer or claim disease, bleeding, pain, urgency, fever, vomiting, treatment, causation, or whether a food is safe. It must not replace professional care, suppress deterministic red-flag escalation, or present a suggestion as a diagnosis.
|
||
|
||
### Release authority
|
||
|
||
Hermes/Timmy is the release authority for routine engineering, test, build, deployment, and release-candidate preparation. Automated evidence must remain reproducible and must not overstate model accuracy or safety.
|
||
|
||
### Human gates
|
||
|
||
Human gates are limited to:
|
||
|
||
1. clinical and privacy review when language or policy crosses those boundaries;
|
||
2. beta consent before participation;
|
||
3. RC approval before shipping a release candidate.
|
||
|
||
Routine provisioning, deployment, label sweeps, and release-candidate assembly are not human-operated gates.
|
||
|
||
## Consequences
|
||
|
||
- Model output is assistive and fail-closed, never authoritative.
|
||
- A generic open-weight VLM can support bootstrap experiments but cannot become the production Bristol classifier without the documented calibration and evaluation evidence.
|
||
- Release evidence and demonstrations must use fictional or synthetic data and state the non-diagnostic boundary honestly.
