Natural language carries emotional texture.
No explicit mood form is required, so the interaction can remain human.

Private single-user trial
Conversation became a signal. Validity did not.
Bae explores whether natural conversation can produce useful wellness-shaped records without turning every feeling into a form.
That possibility creates an ethical problem before it creates a product opportunity: extraction can surface something the user did not explicitly choose to report.
01
Two synchronized traces
One conversation.
Two interpretations.
The visible layer is a companion exchange. Behind it, a constrained extractor decides whether the language contains enough evidence for a HealthKit-shaped State of Mind record.
Visible / companion
Hidden / extraction
02
The consent boundary
A signal cannot bypass
the person it describes.
Consent and paused states sit before extraction. A kill switch stops the system. Safety boundaries remain active even though the interaction is companion-first rather than clinical.
The deeper tension is not solved by a toggle: a system can infer something sensitive from ordinary conversation without the user deliberately reporting it. This remains the central design question.

Only clear, supported signals become records.
If the conversation does not provide enough evidence, nothing is saved. Any saved mood labels must use Apple Health’s approved terms.
03
What 19 / 19 means
Reliable transport.
Not reliable inference.
Nineteen extracted records moved through the sync API and entered Apple Health exactly once. That validates the bridge, its identifiers and mark-synced behavior.
It does not validate whether the emotional interpretation was correct, clinically meaningful, helpful or safe. A technical integration result cannot stand in for efficacy.
The open test is physiological correlation.
The Watch pipeline for HRV, resting heart rate and sleep is staged, not active. No correlation has been run. Validity remains a research question.
04
The non-negotiable boundary
Private experiment. One user. No therapeutic or clinical claim.
Bae is not therapy, diagnosis, treatment or a medical product. It has not demonstrated emotional accuracy or health benefit. The system stays private because sensitive conversational and wellness data cannot become portfolio evidence. Only its interaction model, transport result and unresolved ethical problem are public.
