This is a static research-lens exercise, not an autonomic-regulation guide. It supplies every fictional signal and threshold needed to classify four records. Do not change breathing, stare at a display, induce arousal, use a wearable, seek a lower heart-related value or treat the rows as personal targets. Respiratory pattern, pupil diameter, heart-rate variability, subjective arousal and task accuracy are non-equivalent. Several may move together, separately or in opposite directions. A configured short-term pattern does not prove emotion, safety, judgment, treatment effect, unique superiority, retention or durable real-world control. No practical biofeedback or regulation method is authorised here.
This dossier explains the evidence and its limits. It is not a diagnosis, personal recommendation, assessment, clearance, performance promise or training programme. Actionable teaching appears only when the canonical Power record explicitly authorises it.
Complete bounded explanation
What this power means.
Capability to develop or express autonomic arousal downregulation in a declared context without inheriting broader claims.
What the current evidence supports
Some adults can learn short-term downregulation of declared arousal-linked signals with feedback.
How to observe or measure it without overclaiming
Pupil diameter, respiratory pattern, HRV and subjective arousal are related but non-equivalent signals; none alone establishes emotional state or clinical recovery.
Myth
Become unshakably calm
Metric
Declared physiological recovery time plus calibrated task performance under stress
Boundary
A lower signal does not prove safety, judgment or mental-health treatment.
Negative and limiting findings
No unique superiority over mindfulness or physical activity was shown in one comparative trial.
Durable emotional and real-world transfer remains unestablished.
Claims this evidence cannot support
switch off stress on command
control adrenaline at will
biofeedback cures anxiety
calmness proves safety or competence

This is a static research-lens exercise, not an autonomic-regulation guide. It supplies every fictional signal and threshold needed to classify four records. Do not change breathing, stare at a display, induce arousal, use a wearable, seek a lower heart-related value or treat the rows as personal targets. Respiratory pattern, pupil diameter, heart-rate variability, subjective arousal and task accuracy are non-equivalent. Several may move together, separately or in opposite directions.

Frame the questionState the capability claim narrowly enough that evidence could support or limit it.
Map the evidenceDistinguish existence, measurement, trainability, retention, transfer, safety and functional value.
Find uncertaintyIdentify small samples, proxy measures, missing controls, null findings and unresolved authority questions.
Compare alternativesConsider competing explanations and what evidence would change the current treatment.
Stay non-operationalUse the record for research literacy only until a separate gate authorises instruction.
Authority boundary: Titan teaches a complete Power-specific research method because operational capability practice is not currently justified. The method is Power-specific; its actionability follows this treatment.
Citation roles are explicit. A source may support existence or trainability while simultaneously limiting transfer, certainty, generalisation or safety.

Current teaching and evidence boundary
The next gate remains visible.
No external confirmation is required for the current bounded explainer permission. Guide permission remains not ready; any guide, stronger efficacy, generalisation, protocol, promotion or independent-validation claim requires a new adjudication.
A complete governed research tutorial is available at /tutorials/pwr-042/. It supplies a fictional record-analysis method, worked example, corrections, delayed review and evidence boundary. It does not authorise capability self-practice.
