SSM-Audit – Implementation Guide (2.7–2.9)

2.7 — Stamped logs (optional, one line of ASCII)
Tamper-evident, replayable provenance that never alters m. Enable only if you want an audit trail.

# Per-file (or per-day) stamp format
SSMCLOCK1|iso_utc|rasi_idx|theta_deg|sha256(file)|chain

# Chain bootstrap and step
chain_0 := "0"*64
chain_k := sha256( ascii(chain_{k-1} + "|" + stamp_core_k) )

# Daily anchor (optional)
rollup_D := sha256( ascii(Stamp_1 "|" ... "|" Stamp_n) )

# Notes
# - iso_utc := "YYYY-MM-DDTHH:MM:SSZ" (no leap-second :60)
# - rasi_idx in {0..11}, theta_deg in [0,360)
# - Stamps carry no PII; they are advisory evidence and do not change m

2.8 — Dashboards (executive and owner views)

  • Executive widget: keep the usual m line/table; add a small badge for band (A++/A+/A0/A-/A--).
  • Owner widget: trend of a with band shading; click-through to the stamped CSV.
  • Slice weekly: by segment/region/age bucket to expose stability debt that blends can hide.
  • If using ZEOZO/SYASYS: show Z and A (alignment) and optionally Delta, Q, SyZ for readiness context; calm periods show A >= Z.

2.9 — Conformance CI (what runs every day)
Define a numeric tolerance and evaluate the published CSV against the manifest. Emit PASS/WARN/FAIL per check.

# Inputs
csv: time, kpi, m, a, band, knobs_hash, build_id, stamp
manifest: canonical ASCII (declared knobs, bands, policies, mappings)
sort: time ascending, then kpi ascending
eps_num := 1e-12

Core checks

# Clamp safety
C1:  a := clamp(a, -1+eps_a, +1-eps_a)  -> require -1 < a < +1

# Collapse parity
C2:  phi((m,a)) == m  -> require equality at every hop

# Band parity
C3:  band == band_from_a(a, thresholds)

# Order test (batch == stream == shuffled)
C4:  u_i := atanh(a_i)
     a_fuse := tanh( SUM w_i*u_i / max(SUM w_i, eps_w) )
     require |a_batch - a_stream| <= eps_num
             |a_batch - a_shuffled| <= eps_num

# Ratio parity (for m := f/g)
C5:  a_pre  := tanh( atanh(a_f) - atanh(a_g) )
     a_post := recomputed by declared ratio mapper
     require |a_pre - a_post| <= eps_num

# Rollup parity (nested == flat)
C6:  a_flat   := tanh( SUM w_i*atanh(a_i) / max(SUM w_i, eps_w) )
     a_nested := same fusion level-by-level
     require |a_flat - a_nested| <= eps_num

# Deterministic export
C7:  rerun with same CSV and manifest -> identical a and band (after formatting)

# Knobs fingerprint
C8:  knobs_hash == sha256( ascii(canonical_json(manifest_wo_checksum)) )
     any knob change must flip knobs_hash

# Stamps (if enabled)
C9:  chain_k := SHA256( chain_{k-1} + "|" + stamp_core_k ), chain_0 := build_id
C10: rollup_D := SHA256( join_all_chain_k_for_day )  -> recompute exactly

# Hysteresis sanity
C11: promotions require delta_a >= promote; demotions require delta_a <= demote

Outcome policy

PASS: all checks within eps_num; no rule violations
WARN: only non-material issues (e.g., optional stamp column absent while stamps disabled)
FAIL: any parity/determinism breach, hysteresis violation, or cryptographic mismatch
