Local-first environmental truth

Environmental truth with time, source, uncertainty, and refusal intact.

W-X is LAKANA's local-first environmental-truth layer. It combines supported official reference data, calibrated W-X nodes, and explicitly opt-in local witness devices to evaluate environmental state, freshness, physical plausibility, source agreement, uncertainty, and local divergence. It operates alongside Mesonet-class networks, NWS, ASOS, radar, satellites, meteorologists, and emergency managers. It does not replace them.

What this is not

W-X does not replace Mesonet-class networks, the National Weather Service, ASOS, radar, satellites, meteorologists, or emergency managers. It does not issue official warnings and cannot supersede one.

Official products remain the authority for official warnings. W-X adds local density, freshness, plausibility, and uncertainty beneath and alongside them.

Snapshot computed by the public-safe W-X engine at 2026-08-02 19:46 UTC for boundary cell cell:704:-1949:1984111. Every figure on this page is engine output, not illustrative copy.

Alongside Mesonet-class infrastructure

These layers do different jobs. The regional network supplies calibrated reference and long-term baselines; W-X supplies sub-grid local density that a regional network is not designed to resolve.

Mesonet-class reference

Regional calibrated reference, long-term baseline, official context, and calibration tie-point. Read-only to W-X: retained with its original issuer and timestamp, never relabeled.

W-X fixed nodes

Local microclimate and sub-grid environmental density at declared siting, height, and exposure.

Opt-in phone witnesses

Limited pressure, time, and coarse-location support, or a consented external sensor. Never a substitute for a weather station.

Result

Complementary local environmental truth with explicit divergence from the regional reference — not a replacement network.

Local divergence indicates a difference between the immediate W-X micro-environment and the selected regional reference. It is not a declaration that the official reference is incorrect.

From source to truth, and who owns each step

This is the actual execution path. Each step names the authority that owns it; no step is owned by two.

Observation arrivesOfficial reference, calibrated W-X node, general node, opt-in phone witness, or consented external sensor.Source

W-X determines the bounded environmental truth state. TSARO determines whether a proposed use of that truth is physically and safely admissible.

What each source class may establish

The phone row is the one most often overstated elsewhere. A phone barometer is a real measurement of ambient pressure; a phone is not a weather station.

Source class	Pressure	Air temp / humidity	Wind / radiation	Precip depth	Public identity
Official reference	yes	yes	yes	yes	named issuer, read-only
Calibrated W-X node	yes	yes	yes	gauge only	may be named
General W-X node	yes	yes	siting-limited	gauge only	may be named
Opt-in phone witness	yes, with consent	never	never	never	never named publicly
Connected external sensor	per capability	per capability	per capability	gauge only	keeps its own identity
Human observation	no	no	no	event only	never named publicly

The capability ceiling is structural, not advisory

A phone has no ambient-temperature, humidity, wind, radiation, or rain-gauge sensor. Granting every consent scope does not change that: consent governs privacy, the capability ceiling governs physics. The engine refuses these variables from a phone source regardless of what the device claims.

The W-X Boundary Layer

A privacy-preserving, opt-in, local environmental observation overlay composed of calibrated W-X nodes, supported external sensors, user-authorized phone witnesses, and read-only official reference anchors. It spatially densifies local environmental context beneath and alongside established weather infrastructure.

Terminology

“Boundary Layer” is the LAKANA system label for the local observation overlay. It does not claim to reconstruct the full atmospheric planetary boundary layer or replace standard vertical-profile observations.

Official reference anchor — read-only, retains its issuer

Calibrated W-X node

General W-X node — wider uncertainty

Phone witnesses — count only, never located

Coarse aggregation cell

Accessible equivalent of the map above.
Cell	Reference anchors	Calibrated nodes	General nodes	Phone witnesses	Divergence
A	1	2	1	4	Aligned with reference
B	0	1	2	7	Local microclimate divergence
C	1	0	1	0	Aligned with reference
D	0	0	0	3	W-X insufficient support

Contributor positions are never published. Phone witnesses appear only as a per-cell count, and a cell is a coarse aggregation area, not an observation footprint.

Phone participation is off until you turn it on

This is a recorded deterministic demonstration of the W-X consent and capability gate. No live device contribution is submitted from this section.

Recorded fixture — not a current engine execution

The admitted/refused decision shown below for each variable was computed by the server engine when this page was generated, at a fixed clock of 2026-08-02 19:46 UTC, and the output was written into the page. It is reproducible and it is real engine output, but it is a recording. It does not update, and it is not evidence of current conditions.

For output computed at the moment you ask for it, use the live console. That console calls the server on every request; the mathematics never runs in your browser.

Default state

With no consent granted, the device contributes nothing. There is no implicit grant and no default-on path.

After granting pressure and time-sync scopes

What the gate actually decides

Requested variable	Decision	Label	Ceiling / reason
`stationPressureHpa`	admitted	PHONE PRESSURE WITNESS	SUPPORTING_ONLY
`airTemperatureC`	refused	UNSUPPORTED FOR THIS VARIABLE	a phone has no supported sensor for airTemperatureC; consent cannot create a capability the hardware does not have
`relativeHumidityPct`	refused	UNSUPPORTED FOR THIS VARIABLE	a phone has no supported sensor for relativeHumidityPct; consent cannot create a capability the hardware does not have
`windSpeedMps`	refused	UNSUPPORTED FOR THIS VARIABLE	a phone has no supported sensor for windSpeedMps; consent cannot create a capability the hardware does not have
`precipitationAmountMm`	refused	UNSUPPORTED FOR THIS VARIABLE	a phone has no supported sensor for precipitationAmountMm; consent cannot create a capability the hardware does not have

Two capabilities the device declared — ambient temperature and humidity — were dropped at construction because they are not in the allowed set. They cannot be re-enabled by consent.

Never requested

The W-X contribution flow does not request microphone, audio, camera, photos, contacts, call log, SMS, browsing history, advertising identifiers, health records, or payment data. Revocation stops future contribution and future authorized release; it does not retroactively delete an already-published aggregate.

Live engine console

Every value below is computed on the LAKANA server and sent here as a finished result. This page holds no psychrometric formula, no wet-bulb solver, no fusion rule, and no threshold. It is a view of an answer, not a second copy of the engine.

This console requires JavaScript to call the server. Without it, no value is shown here — the page does not compute a stand-in. The recorded fixtures elsewhere on this page read completely without JavaScript.

What happens when the server cannot answer

Nothing is computed here. The console reports that the engine is unavailable and shows no value. It does not fall back to a browser calculation, does not reuse the previous answer as if it were current, and does not interpolate. A page that silently substitutes an approximation for a refused answer is less honest than one that says it cannot answer.

Scenario laboratory

Recorded fixture — not a current engine execution

Each scenario below was computed by the server engine when this page was generated, at a fixed clock of 2026-08-02 19:46 UTC, and the output was written into the page. It is reproducible and it is real engine output, but it is a recording. It does not update, and it is not evidence of current conditions.

For output computed at the moment you ask for it, use the live console. That console calls the server on every request; the mathematics never runs in your browser.

Each scenario exists to show a specific refusal or degradation. Expand any one to see the full engine output including what it rejected.

Temperature and humidity only — WBGT refused — valid

The most common way a heat figure is overstated. Without radiation and wind there is no globe term, so there is no outdoor WBGT.

What the engine said, and why

WBGT requires a globe temperature (measured or derivable). globe temperature cannot be derived without solar radiation; the radiant load is exactly what the globe term carries. A WBGT cannot be computed from temperature and humidity alone.

Where this truth goes

SOS, SSI, and WX-Ag consume the same truth object. That is what prevents them from disagreeing about the weather.

To SSI — environmental context

01 CivOS Reported sensor and compute availability for the active cell. 02 W-X Established bounded environmental truth for the cell: VALID. 03 W-X->SSI adapter Converted W-X thermal truth into an SSI environmental context.

SSI receives: WBGT 28.35 °C via ESTIMATED_LIMITED_WBGT, confidence SUPPORTED, truth state VALID.

W-X calculates temperature, humidity, pressure, dew point, wet bulb, globe temperature, WBGT, and environmental uncertainty. SSI calculates the personal structural and thermal consequence of that environment. SSI does not compute a separate weather truth.

To SOS — alert candidate, then TSARO

01 W-X Established environmental truth state VALID for the cell. 02 W-X Proposed a local environmental state candidate (W-X LOCAL HEAT CONDITION) for TSARO evaluation. 03 TSARO [DEGRADE] hazard evidence rests on an estimated-limited quantity

Official warning

Issuer: National Weather Service
Product: Heat Advisory
Class: OFFICIAL_WARNING

Issued by the official authority named. LAKANA does not issue, modify, or supersede official warnings.

LAKANA local state

Class: W-X LOCAL HEAT CONDITION

This is a LAKANA local environmental state derived from W-X observations. It is not an official weather warning.

A candidate is not an alert. TSARO returned DEGRADE — hazard evidence rests on an estimated-limited quantity. TSARO consumed the truth object without recomputing it.

To WX-Ag — field consequence

WX-Ag consumes this same truth object. Its full treatment lives on the WX-Ag Field Consequence Laboratory.
