Open to adopt. Impossible to dilute. Honest about duty-of-care and costs.
What this section guarantees
- Open to use: Anyone may implement value, align, band, manifest_id, and stamp without permission.
- Independence: SSMDE is its own standard—not a wrapper for transport/schema formats.
- Interoperability without dilution: Carry SSMDE inside your existing envelopes, but do not change meanings.
- Attribution & integrity: Credit the concept name; do not rebrand core fields.
- Safety clarity: SSMDE improves accountability; it does not replace human judgment or domain procedures.
- Transparent trade-offs: Compute, payload, and policy discipline are real costs exchanged for portable, replayable truth.
Recap of the core SSMDE contract (for legal/ops readers)
What travels together and why
value # untouched fact; collapse parity: phi((m,a)) = m
align # bounded dial in (-1,+1); computed via clamp → atanh → fuse → tanh
band # human/policy stance from manifest cutpoints
manifest_id # immutable rulebook identifier
stamp # one-line time+integrity+order proof (e.g., SSMCLOCK1|...|sha256=...|prev=...)
Key invariants
-1 < align < +1
batch == stream == merged_shards # order-invariant fuse
band := band_from_align(align, manifest_id)
Positioning: what SSMDE standardizes (and what it doesn’t)
Standardizes
• Declared meaning attached to a state (align, band)
• Policy provenance (manifest_id)
• Verifiable timing/order (stamp)
Does not standardize
• Sensor physics, finance ledgers, model training, or plant chemistry
• Your transport, file format, or database schema
Plain statement of scope
“When you publish a state, publish how you judged it — and enough proof that you didn’t rewrite history later.”
Interoperability, without losing the identity of SSMDE
Allowed patterns (product-agnostic)
• Bus/Webhook: embed {value, align, band, manifest_id, stamp} in your payload
• Files/Bulk: add SSMDE columns to CSV/Parquet without touching legacy keys
• DB/Warehouse: store fields as first-class columns; index by manifest_id and time
Non-negotiable meanings
value := the exact observed/computed magnitude (no smoothing/renorm)
align := bounded dial from clamp → atanh → fuse → tanh (or declared equivalent)
band := label derived from declared cutpoints and response windows
manifest_id := resolves to a replayable, immutable manifest
stamp := tamper-evident timing+order chain (not just a timestamp)
Why adopters and the origin both stay protected
Adopters can ship SSMDE freely (no fees/registration) and keep their stack.
The origin remains recognizable: no one may dilute field meanings and still call it “SSMDE.”
Reality check: benefits vs costs
Benefits
• Comparable risk across vendors/sites (align)
• Policy clarity and versioning (manifest_id, band)
• Evidentiary timelines (stamp)
Costs
• Extra compute for align (bounded math)
• Slightly larger messages (band, manifest_id, stamp)
• Cultural discipline (declare response windows; no silent threshold shifts)
Net effect: small, explainable overhead → audit-ready accountability.
