SSM-Clock Stamp – Minimal Test Vectors (13)

Purpose. Byte-accurate, copy-pasteable vectors to validate any implementation of SSM-Clock Stamp (SSM-CS). Everything is strict ASCII; all formulas appear in inline code.

Common parameters (apply to both variants)

  • Seed: chain_0 = "0"*64
  • Times and angles (deterministic from UTC):
    wrap360(x) = x - 360*floor(x/360)
    theta_deg = wrap360( (unix_seconds / 86400) * 360 )
    rasi_idx = floor(theta_deg / 30)
    (print theta_deg with exactly 5 fractional digits; IEEE-754 binary64, ties-to-even)
  • Chain rule: chain_k = sha256( ascii(chain_{k-1} + "|" + stamp_core_k) )
  • Stamp core: stamp_core_k = "SSMCLOCK1|" + iso_utc + "|" + rasi_idx + "|" + theta_deg + "|" + sha256(file)
  • Full line: SSMCLOCK1|iso_utc|rasi_idx|theta_deg|sha256(file)|chain
  • Daily roll-up (anchor): rollup_D = sha256( ascii(Stamp_1 "|" ... "|" Stamp_n) )
    (canonical sort by (iso_utc, stamp_core, chain); no kv: tail used here)

How to use these vectors (quick check)

  1. Hash: recompute h' = sha256(file_bytes) and compare to sha256(file) in each line.
  2. Clock: from iso_utc, compute theta_deg/rasi_idx and confirm
    rasi_idx == floor(theta_deg/30) and the printed theta_deg matches exactly 5 decimals.
  3. Chain: with chain_0 = "0"*64, verify
    chain_k == sha256( ascii(chain_{k-1} + "|" + stamp_core_k) ) for each record.
  4. Roll-up: canonically sort by (iso_utc, stamp_core, chain), join with literal |, and check
    rollup_D == sha256( ascii(joined) ).

Notes. Keep all content 7-bit ASCII; | is the only delimiter; no spaces; all digests are lowercase 64-hex. Do not copy from rich editors—use raw bytes exactly as listed.
