With a qualified clinician, the learner completes familiarisation and a declared set of calibrated warm and cool trials, producing separate site-specific detection results with symptoms and equipment settings recorded.
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 thermal discrimination in a declared context without inheriting broader claims.
What the current evidence supports
People discriminate warm and cold, but thresholds depend strongly on body site, age and body state; durable enhancement through training is not established.
How to observe or measure it without overclaiming
Use calibrated noninjurious warm/cold detection thresholds at a named site and starting temperature; never equate detection with tissue safety or thermoregulatory control.
Myth
Temperature-proof skin
Metric
Calibrated warm/cold threshold by body site and state
Boundary
Detection does not establish tolerance, tissue safety, core-temperature control or training.
Negative and limiting findings
Whole-body cooling changes local sensitivity rather than simply improving it.
No mapped primary study established retained thermal-discrimination training.
Claims this evidence cannot support
Become immune to heat or cold
Train away burn warnings
Cold exposure sharpens thermal sense
A threshold proves metabolic or autonomic control

How to learn this Power now.
With a qualified clinician, the learner completes familiarisation and a declared set of calibrated warm and cool trials, producing separate site-specific detection results with symptoms and equipment settings recorded.
Get readyTell the clinician about skin damage, altered sensation, circulation issues, recent injury, medication changes and prior adverse reactions.
Learn the method6 concrete steps teach the permitted method from start to finish.
See right and wrong4 comparisons show correct or safer execution beside common wrong or riskier choices.
PractiseTesting or practice frequency, trial count and any repeat are set by the qualified clinician for the declared purpose. A repeat uses the same site, device, starting temperature, rate, response rule and rest unless the change is explicitly the question.
Check progressUse the calibrated device protocol to record response temperature for each valid trial, catch-trial behaviour, within-session spread and symptoms; the clinician applies the declared summary rule.
Authority boundary: Titan teaches the complete method; a qualified person controls the parts that require supervision, clearance, specialist equipment, load, dose or progression. 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.
External confirmation is required before higher-authority use because: a clinical, high-risk or regulated configuration; a restricted safety or legitimacy boundary.
A Power-specific tutorial is available at /tutorials/pwr-083/. It contains a plain-English method, 6 ordered steps, a worked example, right-versus-wrong comparisons, specific mistakes and corrections, practice, measurement, accessibility, stopping rules and evidence. Its supervised mode remains controlling.
