SSM-Clock Stamp – Reference Interface & Operational Playbook (4)

Purpose. A minimal, implementation-agnostic offline interface and repeatable workflows for SSM-Clock Stamp. All inputs/outputs are plain ASCII; comparisons are string-based.

What this section provides (at a glance)

  • Commands (normative semantics): stamp, verify, anchor-make, anchor-verify, verify-all.
  • Canonical behavior: fixed prints, ASCII-only hashing inputs, leap-second ban.
  • Expected outputs: concise, copy-ready stdout lines.
  • Failure mapping: deterministic reasons → actions.
  • Minimal pseudocode: portable verifier outline.
  • Operational playbook: stamp → verify → daily anchor → audit → incident response.

Design rules (recap, must)

  • One-line stamp: SSMCLOCK1|iso_utc|rasi_idx|theta_deg|sha256(file)|chain[|kv:...]
  • Clock: theta_deg = wrap360( (unix_seconds / 86400) * 360 ); rasi_idx = floor(theta_deg / 30)
  • Chain: chain_k = H_chain( ascii(chain_{k-1} + "|" + stamp_core) ) with chain_0 = "0"*64
  • Anchors: rollup_D = sha256( ascii(Stamp_1 "|" ... "|" Stamp_n) ) after canonical sort
  • Float/print: IEEE-754 binary64, theta_prec fixed digits (default 5), round-half-to-even
  • Digests: lowercase 64-hex; all hash inputs are exact ASCII of the shown concatenations
  • Leap second: 23:59:60 is forbidden (reject)

What you need to implement

  • File hashing with streaming equivalence (H_algo in {sha256, sha3_256, blake2b-256})
  • UTC parser that rejects offsets/subseconds and :60
  • Fixed-digit angle formatting with banker’s rounding
  • Chain rewalk that can vary chain_algo per row
  • Canonical daily selection + ordering + join for anchors
  • Strict kv: parsing with defaults and domain checks; ignore unknown keys
