InstaCalc Self-Hosting Migration Dashboard & Scorecard

Component Migration Scorecard Breakdown by architectural subsystem

1. Visual Art & Sprite Assets (ASCII Palettes & Matrices) 100% in .ic

2. Game Simulation Kernels & Physics (SoA @ 120M ticks/s) 90% in .ic

3. Procedural Audio Engine (Chords, ADSR, FM Ratios) 80% in .ic

4. Standard Library & Math Functions (Pure .ic + Lowered) 44% pure / 100% declarable

5. Tokenizer & Parser AST Infrastructure (Host Pratt/Nearley) 20% (.ic escape hooks)

Function	Module / Domain	Status	Representation in .ic vs JS
acosh(x)	trig.ic	Pure .ic	ln(x + sqrt(x^2 - 1))
clamp(x, min, max)	shaping.ic	Pure .ic	min(max(x, min), max)
vec_dist(x1,y1,x2,y2)	geom.ic	Pure .ic	sqrt((x2-x1)^2 + (y2-y1)^2)
pmt(r, n, p, f, t)	excel.ic	Pure .ic	if(r==0, -(p+f)/n, -(r(f+p(1+r)^n))/((1+rt)((1+r)^n-1)))
fibonacci(n)	math.ic	Pure .ic	round((1.618^n - (-0.618)^n) / 2.236)
reduce(arr, fn, init)	IcCompiler Lowering	Lowered .ic	Monomorphic for-loop (0 heap allocations)
average(arr)	stats.ic	Lowered .ic	reduce(arr, (a, b) => a + b, 0) / count(arr)
gcd(a, b)	math.ic	Lowered .ic	Euclidean loop lowering in .ic
nsolve(fn, guess)	solver.ic	Lowered .ic	Bounded Newton-Raphson iteration loop
stdev(arr)	stats.ic	Lowered .ic	sqrt(average(map(arr, x => (x - avg)^2)))
round(x, [unit])	Scalar Units	Host JS	`Math.round(x)` (lifts compound unit algebra)
nchoosek(n, k)	Combinatorics	Host JS	Arbitrary-precision BigInt factorial product
cagr(...)	Financial Types	Host JS	Returns percentage format descriptor
fetch(url)	Host I/O	Host JS	Browser Fetch API / Network bridge
