Principle. Roll out read-only first, prove value with logs and stamps, then enable advisory hooks, and only after a safety case, consider scoped closed loop. Collapse parity must hold at every boundary: phi((m,a)) = m. Clamp everywhere: a := clamp(a, -1+eps_a, +1-eps_a).
5.1 — Rollout modes (pick one to start, upgrade later)
• Read-only (recommended start). Publish the confidence lane beside 3–5 KPIs; no actuator changes.
• Advisory scheduling. Use bands to shape non-critical gains, guards, debouncing, smoothing; actuators still keyed to m.
• Targeted closed loop. After evidence and a safety case, enable narrow, reversible policies that reference bands.

5.2 — Week-1 pilot blueprint (copy once, use everywhere)
• Choose KPIs. Ratios near zeros, fusion outputs, observer estimates, top perf/watt counters.
• Wire the lane. Emit (m,a) for each KPI with eps_a=1e-6, eps_w=1e-12; weights default w_i := |m_i|^1.
• Band the UI. Show A++/A+/A0/A-/A-- next to each KPI; keep raw values fully visible.
• Stamp outputs. Append a tiny ASCII manifest (knobs, build, checksum) to logs/CSVs.
• A/B window. 2–4 weeks baseline vs lane-visible runs; identical actuator logic.
• Decide. Promote if waste/false alarms/oscillations fall and classical outputs remain identical.
Pilot scaffold (drop-in Python; plain ASCII).
from math import atanh, tanh
import json, hashlib, os
EPS_A = 1e-6
EPS_W = 1e-12
BANDS = [-1.00, -0.90, -0.60, 0.60, 0.90, 1.00]
BUILD_ID = os.getenv("SSMH_BUILD_ID", "build_abc123")
def clamp_a(a):
return max(-1 + EPS_A, min(1 - EPS_A, a))
def band_of(a):
return "A++" if a >= 0.90 else "A+" if a >= 0.60 else "A0" if a > -0.60 else "A-" if a > -0.90 else "A--"
def manifest(knobs, build_id, conformance_checksum):
blob = {"knobs": knobs, "build_id": build_id, "conformance_checksum": conformance_checksum}
j = json.dumps(blob, sort_keys=True)
return j, hashlib.sha256(j.encode("ascii")).hexdigest()
def write_row(f, ts, kpi, m, a, b, knobs_hash, build_id, note=""):
f.write(f"{ts},{kpi},{m:.6f},{a:.6f},{b},{knobs_hash},{build_id},{note}\n")
knobs = {"eps_a": EPS_A, "eps_w": EPS_W, "bands": BANDS}
manifest_json, manifest_sha = manifest(knobs, BUILD_ID, "CONFORMANCE_SHA256_HERE")
print("SSMH-STAMP manifest_sha256=", manifest_sha)
Notes for operators (plain text).
• Emit KPI with lane, band, and a daily stamp.
• Write manifest_json once per day to a stamp file; write rows per sample to a CSV.
