SSM-JTK – Summary (0C)

In short, SSM-JTK is a self-contained, ephemeris-free transit kernel: per-body JSON manifests plus a compact evaluator
L_hat_deg := wrap360(a0 + n*t + SUM_k( c_k*sin(omega_k*t) + d_k*cos(omega_k*t) ))
with t := days_since(D, t0) (time base: 05:30 IST). Daily outputs map to rasi via
rasi := floor((L_hat_deg % 360)/30)
and enforce node identity
Ketu(t) := wrap360(Rahu(t) + 180).

The materials include a golden day-grid CSV (daily 1990–2030), the per-planet manifests, a pure-stdlib validator, and an acceptance log. All checks PASS at tol = 1e-5 after wrap360.

For deep time, the same kernel supports monthly benches across years 0001–9500 (kept as a sampler outside this minimal set). Integrity is reinforced by publishing the SHA-256 of the golden CSV in the documentation.

Everything is offline, deterministic, and plain-ASCII auditable; SSM’s alignment channel travels with numbers for stability readouts while phi(m,a) = m preserves classical arithmetic.
