SSMDE — How to Start (0E)

Day 1: ship truth without breaking anything. Day 30: defensible accountability.

Day 1 — Add SSMDE alongside what you already send

Keep your current transport (JSON/CSV/bus/API). Add one portable declaration block per message.

Minimal block (copy-ready):

{
  "value": { "reading": 36.9, "unit": "C" },
  "align": 0.12,
  "band":  "A0",
  "manifest_id": "M1",
  "stamp": "SSMCLOCK1|2025-11-04T13:20:55Z|theta=127.4|sha256=9f...21|prev=NONE"
}

What each field means (at Day 1):

value        # untouched classical magnitude (collapse parity holds: phi((m,a)) = m)
align        # bounded dial in (-1,+1); start with a simple computed or conservative value
band         # human stance like "A0"; map to a small published band table
manifest_id  # short ID of the rulebook in force (fixed for Day 1)
stamp        # time + digest + prev link; Day 1 may start with prev=NONE

Safety dial math (canonical pipeline to adopt):

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

Set once and publish:

eps_a := 1e-6
eps_w := 1e-12

Tiny Day 1 band table (example):

# align in (-1,+1)
A++ : align >= +0.80
A0  : -0.30 <= align < +0.80
A-  : -0.80 <= align < -0.30
CRITICAL : align < -0.80   # escalate to human

One-line stamp shape (example):

SSMCLOCK1|<utc>|theta=<deg>|sha256=<hex>|prev=<hash-or-NONE>


Day 7 — Make it replayable

Two checks anyone can run:

(1) Verify chain continuity

# Pseudocode:
for each record i>0:
    assert record[i].stamp.prev == sha256( canonical(record[i-1]) )

(2) Recompute align for parity

# Pseudocode:
recompute_align(a_raw_timeline, weights, eps_a, eps_w) -> a_out'
assert approx_equal(a_out', record.align)

Outcome: audit can replay timing and math without your help.


Day 14 — Publish the rulebook (manifest)

Freeze policy in a small, human-readable manifest.

Starter manifest (copy-ready):

{
  "manifest_id": "M1",
  "align_computation": {
    "eps_a": 1e-6,
    "eps_w": 1e-12,
    "weights": "uniform",
    "pipeline": [
      "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) )"
    ]
  },
  "bands": [
    { "name": "CRITICAL", "align_min": -1.00, "align_max": -0.80, "action": "page human", "window": "<= 10 min" },
    { "name": "A-",       "align_min": -0.80, "align_max": -0.30, "action": "investigate", "window": "<= 30 min" },
    { "name": "A0",       "align_min": -0.30, "align_max":  0.80, "action": "monitor", "window": "<= 8 h" },
    { "name": "A++",      "align_min":  0.80, "align_max":  1.00, "action": "none", "window": "n/a" }
  ]
}

Rule: change policy → issue a new manifest_id.


Day 30 — Graduate to defensible accountability

Turn the dial from “nice-to-have” to evidence:

(1) Chain every record

prev := "NONE"
for each canonical_record in stream:
    digest := sha256( canonical_record )
    stamp  := "SSMCLOCK1|" + utc() + "|theta=" + rotation() +
              "|sha256=" + digest + "|prev=" + prev
    prev   := digest

(2) Enforce escalation promises

if band == "CRITICAL":
    page_oncall_within("<= 10 min")
log_escalation_outcome()

(3) Ledger the received declarations

append(local_ledger.jsonl, { record, verified_chain:true, verified_align:true })

Result by Day 30. Records are self-contained declarations with frozen policy, provable timing/sequence, and auditable actions.


Starter Kit (optional, quick lift)

What to paste into your repo today:

Read-me snippet

# SSMDE quick start
# 1) Emit the minimal block alongside your current payload
# 2) Publish a tiny manifest (see M1 above)
# 3) Add chain + verify steps to CI or a nightly job

CI parity check (pseudocode)

job "ssmde_verify":
  steps:
    - recompute_align_against_records()
    - verify_stamp_chain()
    - fail_if_discrepancy()

Band card for operators

CRITICAL : human respond <= 10 min
A-       : investigate <= 30 min
A0       : monitor <= 8 h
A++      : no action
