SSMDE – Scope and claim (2.1)

What SSMDE standardizes—and what it intentionally leaves to you

Plain claim

SSMDE is a symbolic exchange layer for truth-bearing state. It standardizes how a state is sent together with its meaning, policy, and proof—not your transport, file format, or physics.


What SSMDE standardizes (must-haves)

value        # untouched fact; collapse parity: phi((m,a)) = m
align        # bounded stability dial in (-1,+1) via clamp → atanh → fuse → tanh
manifest_id  # immutable rulebook identifier that defines meaning and actions

Strongly recommended (accountability contexts)

band         # human/policy stance derived from align cutpoints in manifest
stamp        # one-line time+integrity+order proof (e.g., SSMCLOCK1|...|sha256=...|prev=...)


What SSMDE does NOT standardize

  • Sensor physics, finance math, clinical protocols, plant chemistry, or model training.
  • Message envelope (bus, file, DB, API) or serialization specifics beyond keeping meanings intact.
  • Your escalation org chart—only the promises must be declared in the manifest.

Minimum compliant record (Day-1)

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


Recommended record (audit-grade)

{
  "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>"
}


Alignment pipeline (normative math)

a_c   := clamp(a_raw, -1+eps_a, +1-eps_a)
u     := atanh(a_c)
U     += w * u
W     += w
align := tanh( U / max(W, eps_w) )

Publish these knobs in the manifest:

eps_a, eps_w, weight_rule := "uniform" | e.g., w := |m|^gamma


Compliant vs non-compliant (quick tests)

Compliant

• value is byte-for-byte what the source produced (phi((m,a)) = m).
• -1 < align < +1 and computed by clamp → atanh → fuse → tanh (or declared equivalent preserving bounds and collapse parity).
• band derived from manifest cutpoints (not hand-labeled).
• manifest_id resolves to an immutable manifest in effect at that timestamp.
• stamp (if present) verifies: sha256(canonical(record)) and prev-chain continuity.

Non-compliant

• value was “smoothed” or re-scaled but still called value.
• align is an unbounded score or ad-hoc opinion string.
• band labels don’t match manifest cutpoints and response windows.
• manifest_id is opaque or mutable post-incident.
• stamp is just a timestamp (no digest, no chain).


One-line scope

SSMDE attaches declared meaning, policy, and replayable proof to every state—without telling you how to build your sensor, ledger, model, or plant.
