SSMDE – Minimal Record Shape (1.6)

The smallest portable unit of fact, stability, policy, and proof

Canonical shape (copy-ready)

{
  "value":       <number-or-struct>,
  "align":       <number in (-1,+1)>,
  "band":        <string>,                  # optional but recommended
  "manifest_id": <string>,
  "stamp":       <string>                   # optional but recommended
}

Intent of each field

  • value → the untouched magnitude or small struct (collapse parity: phi((m,a)) = m).
  • align → bounded stability dial (-1 < align < +1) computed by clamp → atanh → fuse → tanh.
  • band → human / policy label derived from align using manifest cutpoints.
  • manifest_id → the rulebook anchor; must resolve to an immutable manifest.
  • stamp → one-line timing + integrity + chain proof (e.g., SSMCLOCK1|...|sha256=...|prev=...).

Minimal vs Full (pick what you need)

Minimal (Day-1 adoption)

{
  "value":       <number-or-struct>,
  "align":       <number-in-(-1,+1)>,
  "manifest_id": <string>
}

Full (recommended for audit)

{
  "value":       <number-or-struct>,
  "align":       <number-in-(-1,+1)>,
  "band":        <string>,
  "manifest_id": <string>,
  "stamp":       "SSMCLOCK1|<utc>|theta=<x>|sha256=<hex>|prev=<hex-or-NONE>"
}

Type & range guidance (copy-ready)

value         : number | object
align         : float  ; must satisfy -1 < align < +1
band          : string ; e.g., "A++", "A0", "A-", "CRITICAL"
manifest_id   : string ; immutable policy anchor (e.g., "PLANT_A_BEARING_SAFETY_v7")
stamp         : string ; tamper-evident time/order chain (recommended)

Canonical subset (for hashing in stamp)

Keep hashing stable and tiny.

canonical(record):
  {
    "value":       <as-emitted>,
    "align":       <number>,
    "band":        <string-or-null>,
    "manifest_id": <string>
  }

Serialization rules (to avoid drift)

• UTF-8, plain ASCII tokens
• stable key order: value, align, band, manifest_id
• floats as plain ASCII (no locale commas)
• explicit nulls if a field is absent downstream

Validation checklist (producer & consumer)

[ ] phi((m,a)) = m holds for value (collapse parity)
[ ] -1 < align < +1 and computed via clamp → atanh → fuse → tanh
[ ] band matches manifest cutpoints (if present)
[ ] manifest_id resolves to immutable manifest
[ ] stamp (if present) verifies: sha256(canonical(record)) and prev-chain continuity

Two copy-ready examples

Industrial cooling

{
  "value":       { "temperature_K": 296.42 },
  "align":       0.87,
  "band":        "GREEN",
  "manifest_id": "THERMAL_LINE_COOLING_PLANT_A_v7",
  "stamp":       "SSMCLOCK1|2025-11-04T14:05:22Z|theta=132.77|sha256=9fde1c...|prev=72af0b..."
}

Finance collections

{
  "value":       { "cash_collected_usd": 18420.77 },
  "align":       -0.31,
  "band":        "A-",
  "manifest_id": "AR_STABILITY_Q4_CLOSE_v2",
  "stamp":       "SSMCLOCK1|2025-11-04T14:06:41Z|theta=044.91|sha256=ab12d4...|prev=89c2aa..."
}
