Turn raw model scores into accountable actions with bands, manifests, and stamps
Problem → Fit
Problem. A model returns a score or class, but ops still asks: auto-execute or send to a human? Logs lack behavioral honesty and replayable proof.
Fit. With SSMDE, each AI output carries a bounded stability dial, a policy band that drives routing, a manifest that fixes cutpoints and response windows, and a stamp that makes the decision auditable.
Invariant math (behavior dial for any model)
Use the portable, order-invariant pipeline to compute align for the specific output:
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) )
Map to a human/policy band:
band := band_from_align(align, manifest_id)
Collapse parity stays sacred: phi((m,a)) = m
How to derive a_raw (model-specific choices)
Pick one per manifest and declare it; then apply the invariant pipeline above.
a_raw := margin_to_threshold(score, threshold) # classification margin
a_raw := calibrated_confidence(score_cal) # post-calibration output
a_raw := -uncertainty_mc_dropout(var) # negative of predictive variance
a_raw := agreement_ensemble(p_win_consensus) # ensemble agreement
a_raw := drift_inverse(d_data, baseline) # inverse of input/data drift
semantics := "positive = within safe envelope; negative = unstable/uncertain"
What an AI SSMDE record looks like
Minimal (routing-only)
{
value: { decision: "approve_loan", score: 0.912 },
band: "AMBER",
manifest_id: "AI_LENDING_ROUTE_vX"
}
Full (audit-ready)
{
value: { decision: "approve_loan", score: 0.912, featureset_id: "FS_23A" },
align: +0.18,
band: "AMBER",
manifest_id: "AI_LENDING_ROUTE_vX",
stamp: "SSMCLOCK1|2025-11-05T08:42:11Z|sha256=7fa1...|prev=3bc9..."
}
Routing policy (declare once in the manifest)
bands := [
{ name:"GREEN", range:"[+0.30, +1.00)", action:"auto_execute" },
{ name:"AMBER", range:"[-0.20, +0.30)", action:"hold_for_human_review <= 30m" },
{ name:"RED", range:"(-1.00, -0.20)", action:"block_execute; escalate_safety <= 10m" }
]
- Labels are operational authority, not UI colors.
- Response windows are contractual and time-bounded.
Producer workflow (model service)
[ ] Compute a_raw as declared (e.g., margin_to_threshold)
[ ] Run clamp → atanh → fuse → tanh → align
[ ] Compute band via manifest cutpoints
[ ] Emit SSMDE block with manifest_id and stamp
Consumer workflow (orchestrator / guardrail)
[ ] Route by band (GREEN→auto; AMBER→human queue; RED→block)
[ ] Enforce response windows from manifest
[ ] Verify stamp chain, recompute band_from_align
Copy-ready examples
Auto-execute
{
value: { decision: "flag_content_safe", score: 0.981 },
align: +0.62,
band: "GREEN",
manifest_id: "AI_MODERATION_ROUTE_vX",
stamp: "SSMCLOCK1|2025-11-05T07:10:05Z|sha256=f51e...|prev=f0a2..."
}
Human review
{
value: { decision: "approve_with_limits", score: 0.674 },
align: +0.05,
band: "AMBER",
manifest_id: "AI_CREDIT_ROUTE_vX",
stamp: "SSMCLOCK1|2025-11-05T08:42:11Z|sha256=7fa1...|prev=3bc9..."
}
Block and escalate
{
value: { decision: "override_denied", score: 0.541 },
align: -0.47,
band: "RED",
manifest_id: "AI_OVERRIDE_SAFETY_vX",
stamp: "SSMCLOCK1|2025-11-05T09:02:33Z|sha256=2ad4...|prev=7fa1..."
}
Receiver-side verification (defense against vendor drift)
[ ] -1 < align < +1
[ ] band == band_from_align(align, manifest_id)
[ ] stamp.sha256 == sha256(bytes(canonical(record)))
[ ] chain(prev) verifies end-to-end
[ ] phi((m,a)) = m # value untouched by align
Common pitfalls and fixes
- Pitfall: Using ad-hoc smoothing instead of the bounded pipeline.
Fix: Declarea_raw, then only clamp → atanh → fuse → tanh (or an explicitly equivalent, bounded, order-invariant method). - Pitfall: “GREEN means OK everywhere” without numeric ranges.
Fix: Cutpoints and response windows live in the manifest tied tomanifest_id. - Pitfall: Quietly tightening thresholds mid-incident.
Fix: Mint a newmanifest_id; stamps expose the timeline. - Pitfall: Assuming stamped = correct.
Fix: Stamps prove what was declared, when—not physical truth. Keep separate calibration/QA.
Quick start (Day 1 → Day 30)
Day 1
emit { value:{decision:<str>, score:<num>}, band:"<GREEN|AMBER|RED>", manifest_id:"<ID>" }
Day 7
add align; begin stamping:
stamp := "SSMCLOCK1|<utc_iso>|sha256=<...>|prev=<...>"
Day 30
enforce response windows; run weekly replay:
verify band_from_align and stamp chain vs manifest
One-line takeaway
SSMDE turns model outputs into accountable events: bounded stability, declared routing authority, fixed policy, and stamped proof—ready for regulated operations.
