SSMT – Conclusion & Release Guide (10.0–10.6)

Step 1: Emit S1 (Lite)
Emit:
{ timestamp_utc, e_T, manifest_id }
Add health flags if available:
health.range_ok, health.sensor_ok, health.drift
oor if out of declared range

Step 2: Add S2 when freezing matters
Add:
a_phase  (or a_phase_fused for multi-pivot materials)
Q_phase  (soft hysteresis memory dial driven by rho, k_side)
Now you can express “freeze risk” and “clear” using symmetric symbolic bands.

Step 3: Add S3 only when needed
Add:
a_T := tanh( c_T * e_T )
Use this bounded dial for dashboards, pooled fleet rolls, or ML priors.
You MAY also apply pooling:
a_pool = tanh( mean(atanh(a_i)) )
to summarize many sensors safely.

Golden rule:
All alert logic and routing stays symbolic.
°C/°F MAY appear on screens for human comfort,
but machine logic MUST act only on symbols.

HEAT_ADVISORY:
  e_T >= +E_hot for >= T_hot_min

COLD_ADVISORY:
  e_T <= -E_cold for >= T_cold_min

FREEZE_RISK:
  a_phase <= -Phi_freeze for >= T_freeze_min

CLEAR_*:
  dwell-based clear using hysteresis bands
  (for example, e_T <= +E_hot - E_hyst for >= T_clear)

T_K = max( T_K , eps_TK )

Tests:
• Run Tier S1 tests in CI.
  - Unit invariance.
  - Lens domain guards for log / linear / beta / kBT.
  - If hybrid is used: tau > 0 and correct branch swap.
  - If qlog is used: alpha > 0 and zero at T_ref.
  - Clamps for a_T and a_phase.
  - Phase symmetry around T_m.
  - Soft-hysteresis evolution (rho, k_side).
  - Validity/saturation rules.
  - Pooling bounds.
  - Kelvin floor present.

Manifests:
• Freeze one lens for the entire run.
• Publish anchors (T_ref, DeltaT, etc.).
• Publish T_valid_range_K.
• Attach manifest_id to every record.
• Optionally include manifest_hash.
• Record resolved_lens once per run; it MUST NOT change mid-run.

Policies:
• Declare thresholds and dwell in symbol space (E_hot, Phi_freeze, etc.).
• Keep rationale text for each threshold.

Governance:
• No mid-run lens changes.
• Version manifests.
• Any new field MUST be optional and backward-friendly.

Evidence:
• Maintain a short empirical appendix (for example, flicker reduction near freeze bands, threshold portability across sites).
• Keep these results tied to the exact manifest_id and manifest_hash in archive.

Phase 1 — Starter kit
• Publish minimal reference code:
  to_kelvin
  encode_eT for log | linear | beta | kBT | hybrid | qlog
  a_phase
  clamp_a
  pooling
  + JSON schema for manifests

• Include golden vectors (Tier S1).
• Include a tiny CLI harness.
• Document knobs:
  tau (hybrid),
  alpha (qlog),
  eps_TK (Kelvin floor),
  eps_a (clamp for a_T / a_phase),
  eps_w (pooling floor).

• Provide a Policy Pack:
  E_hot, E_cold, Phi_freeze, E_hyst, dwell windows.
• Include accessibility and privacy notes:
  ASCII-only formulas,
  alt-text guidance,
  explicit invertibility notice for e_T.

Phase 2 — Pilot deployments
• Weather / environmental ops with S1 (just e_T) and public advisory-style symbols.
• Cold-chain / handling with S2 (a_phase + Q_phase) and documented pivots.
• Compute / infrastructure / rack cooling with S3 (a_T + pooling).

• Optional edge cases:
  cryogenic regimes use beta or qlog.
  Document tau / alpha.

Phase 3 — Evidence & conformance
• Run Tier S1 tests in CI for every pilot.
• Store manifest hashes and golden outputs.
• Report KPIs in symbol space:
  - reduction in unit-based incident confusion,
  - freeze flicker reduction via hysteresis,
  - threshold portability across sites using fixed E_hot / E_cold.

• Capture privacy posture and accessibility posture for audit.

Phase 4 — Community registry
• Host a registry of manifests:
  - lens choice,
  - knobs,
  - hash / fingerprint,
  - domain tags.
• Accept submissions of symbol-only telemetry + manifest for evaluation.
• Keep an append-only log of lens decisions and golden vectors.

Phase 5 — External alignment
• Present KPIs, manifests, and rulesets to standards bodies.
• Reserve field names and lens semantics so “e_T” means the same thing everywhere.
• Maintain backward compatibility: new fields are optional, and deprecations get long notice.

• Quarterly spec review.
• Accessibility & privacy audit.
• Check that no team slipped into unit-based logic in production.
• Confirm no mid-run lens switches without a new manifest_id.

SSMT v2.3 — YYYY-MM-DD

Spec:
Non-breaking update with four targeted deltas.

Schema:
Schema version "1.1" unchanged.

Addition 1 — Smooth Hybrid lens (continuity-safe)
e_T = s * ln( T_K / T_ref ) + ( 1 - s ) * ( (T_K - T_ref) / DeltaT )
s = 1 / ( 1 + exp( -( abs( T_K - T_ref ) - tau ) / width ) )

Addition 2 — Normalized multi-pivot fusion
z_i      = c_m_i * ( (T_K - T_m_i) / DeltaT_m_i )
W        = max( sum_i w_i , eps_w )
z_bar    = (1 / W) * sum_i( w_i * z_i )
a_phase_fused = tanh( z_bar )

Addition 3 — Adaptive hysteresis (rho by noise)
sigma_T     = std( T_K[t-W+1:t] )
sigma_norm  = sigma_T / DeltaT_m
rho         = clip( 1 - exp( - sigma_norm / sigma0 ) ,
                    rho_min ,
                    rho_max )
Q_phase     = rho * Q_{t-1} +
              (1 - rho) * clip( p_side , 0 , 1 )

Addition 4 — Privacy modes and starter manifests
Addendum J (P0 raw, P1 quantized, P2 DP-lite; anchors policy)
Addendum K (M1/M2/M3 deployment classes)
Cross-referenced in Section 2 for optional privacy / gating blocks.

Document spec:
Describes the symbolic method and rules (for example, v2.3).
This is the human-readable spec.

Manifest / schema version:
Schema label such as "1.1".
This is what devices and services emit/ingest.

Compliance level:
S1 / S2 / S3.
S1 = e_T only.
S2 = add a_phase (+Q_phase).
S3 = add a_T and pooling.

All three must be stated together when you sign off a deployment.
Example:
"We deployed S2 under schema '1.1' following document spec v2.3."
