Intelligent Chemistry Vertical · Intercalation Unit
[ Click to initialise ]
An integration of first, second and intermediate principles, with the
discernment between each held explicit. Every quantity is derived from atomic number alone
and carries the tier it was obtained at — L0 exact, L1 derived, L2 model, L3 fitted.
No element names, property tables or reference data of any kind are present in this file.
Zero dependencies, zero network, single portable document.
This engine derives chemical and physical quantities from atomic number using stated
principles. It is a research and educational instrument. It is not a source of
validated physical constants, and its outputs must not be used for safety-critical,
clinical, structural, industrial or regulatory purposes.
Outputs are labelled by epistemic tier. Only quantities marked L0 EXACT are closed-form
results independent of measurement. L1 DERIVED multiplies an exact result by a measured
constant. L2 MODEL applies an approximation where the exact many-body problem is
intractable. L3 FITTED depends on regression coefficients fitted to external measurement.
Errors of tens of percent are expected and documented in L2 and L3 outputs. Agreement with
reality must be established externally, not assumed from this engine.
Terms of Service
The engine is provided as-is, without warranty of any kind, express or implied,
including fitness for a particular purpose.
All computation occurs locally in your browser. No account, licence key or
registration is required or offered.
You may view, copy, archive and inspect the source of this document. It is delivered
as a single readable file specifically so that its behaviour can be audited.
No liability is accepted for any decision, loss or damage arising from use of the
outputs.
These terms are governed by the law applicable at the operator's principal place of
business. Disputes should first be raised at legal@icy.icu.
Privacy Policy
No data is collected. The engine performs no network requests of any
kind after the document loads.
There are no cookies, no analytics, no telemetry, no trackers, no beacons, no
fingerprinting and no third-party scripts.
No personal data is transmitted, stored on a server, sold, shared or profiled,
because none is received.
Exported archives are assembled in memory and saved directly by your browser. They
never leave your device.
Because no personal data is processed, no data-subject request is necessary; enquiries
may still be sent to contact@icy.icu.
Acceptable Use Policy
Do not present engine outputs as measured experimental values, or strip the tier
labels that identify how each quantity was obtained.
Do not use outputs to make claims about the safety, toxicity, stability, reactivity or
regulatory status of any substance.
Do not use the engine or its outputs in the design, synthesis or evaluation of
weapons, explosives, or materials intended to cause harm.
Do not redistribute modified copies in a way that implies the modifications were
verified here.
Attribution is appreciated but not required. Preserving the tier labels is.
Accessibility
Keyboard operable throughout: Space pause or resume, C copy
proofs, Z export archive, L this document, Esc close.
A skip link to the engine is the first focusable element. Focus is always visible.
prefers-reduced-motion disables the background animation and all
transitions. prefers-contrast: more raises text and border contrast.
Status changes are announced through a live region. Colour is never the sole carrier
of meaning — every tier also has a text label, and every relation a written status.
All content is real text, selectable and machine-readable. No text is baked into
images; there are no images.
Accessibility problems can be reported to contact@icy.icu and will be treated as
defects.
Construction & Integrity
Single HTML document. No external file, stylesheet, font, image, script or CDN.
No third-party or vendored library code of any kind.
No network access at runtime. No service worker, no fetch, no XHR, no WebSocket.
All graphics — icons included — are drawn from code at load time and injected as data
URIs. The manifest is generated in memory the same way.
Audio is synthesised as raw PCM by trigonometric summation and packaged into a RIFF
container written here; no browser audio-processing interface is used.
The archive builder writes ZIP structures and CRC-32 directly.
