ObserverOps Technical Blueprint - IV-VI

Part IV — Metrics & Telemetry

Chapter 19 — Micro Metrics

Goal

Make the inside of an observer measurable. Define, estimate, and gate AL, S_c, Agreement Rate, Mis-exec Rate, and Slot Occupancy/Collisions with rolling estimators, confidence bounds, drift tests, and production threshold bands.

What you’ll implement (checklist)

Emit per-tick events and counters for the five micro metrics.
Rolling window estimators (time or tick windows), plus Wilson CIs for proportions.
Drift detectors (EWMA/CUSUM/Page–Hinkley) for AL/S_c trends.
Green/Amber/Red bands with escalation hooks (alerts + Ô policy nudges).
A minimal /metrics/micro readout and weekly KPI snapshot.

19.1 Definitions (operational)

Attractor Load (AL)

Concentration of the semantic field over orientations/channels at context $x$ , tick $τ$ :

\mathrm{AL}(x,τ) \;=\; \frac{\max_{\theta} w_\theta\,\lVert P\Psi_m(x,\theta,τ)\rVert} {\sum_{\theta} w_\theta\,\lVert P\Psi_m(x,\theta,τ)\rVert + \varepsilon}

High AL ⇒ strong attractor (exploit); low AL ⇒ diffuse (explore).

Collapse Entropy $S_c$

Diversity of recent channel selections inside a rolling window $W$ :

p_\theta(τ)=\frac{\#\{\text{uses of }\theta\in[τ-W,τ]\}} {\sum_{\theta'}\#\{\text{uses of }\theta'\}}\!, \quad S_c(τ)=-\!\sum_\theta p_\theta(τ)\log p_\theta(τ)

Falling $S_c$ = latching to a subset; persistently high $S_c$ = diffusion.

Threshold heuristic seen in field ops: if entropy drops >20% for two ticks while saturation rises, rotate channels/soften curvature (black-hole approach).

Agreement Rate (over commuting overlaps)

For two observers $A,B$ , after frame mapping and lag tolerance, on the set $O$ of commuting overlaps:

\mathrm{Agree}=\frac{\sum_{(k,τ)\in O}\mathbf{1}[y^{A}_{k,τ}=y^{B}_{k,τ}]} {|O|}

Use only keys that commute and share redundant/ledgered records (SBS). Track NCE (non-commuting exposure) separately.

Mis-exec Rate (two facets)

Policy-Violation Rate (PVR): fraction of executed channels that violated compatibility/policy/preconditions at that tick.
$\mathrm{PVR}=\#\text{violations}/\#\text{ticks}$ .
Tool-Error Rate (TER): tool errors or timeouts per external tool invocation. Target ≤ 1.0%.

(Track both; alert if either exceeds bands.)

Slot Occupancy & Collisions

Occupancy per pool $q$ : $\mathrm{occ}_q(τ)=\mathrm{used}_q(τ)/N_q$ .
Collision occurs when an allocation request cannot be satisfied and the policy would need to evict an active/unguarded item; log Slots.Collision with provenance.
Collision rate: $\mathrm{CollRate}=\#\{\text{Slots.Collision}\}/\#\{\text{allocate}\}$ .
Green bands example: memory < 0.5%, tools < 1%, attention ~ 0%.

19.2 Estimators (rolling windows, CIs, drift)

Windows

Use tick-based windows for tight control loops (e.g., last $W=128$ ticks), or time-based (e.g., last 5 min) for fleets. Emit both short (reactive) and long (stable) windows.

Proportions: Wilson CI (recommended)

For Agreement, PVR, TER, CollisionRate, compute Wilson bounds per window:

def wilson_ci(k, n, z=1.96):
    if n == 0: return (0.0, 1.0)
    p = k/n
    denom = 1 + z*z/n
    center = (p + z*z/(2*n))/denom
    half = z * ((p*(1-p)/n + z*z/(4*n*n))**0.5) / denom
    return (max(0.0, center - half), min(1.0, center + half))

(Attach the CI to every alert to avoid chasing noise.)

Rolling AL/S_c

Maintain streaming sums/histograms per $θ$ to update $S_c$ in $O(1)$ .
For AL, cache $\lVert P\Psi_m\rVert$ per $θ$ ; update the ratio each tick.

Drift detectors

EWMA/CUSUM on $S_c$ and AL to catch slow drift; Page–Hinkley for sudden regime shifts. Trigger “Amber:Drift” if statistic exceeds tuned band for $L$ ticks.
Couple $S_c$ drift with saturation signals: only escalate entropy drops that co-occur with rising saturation (black-hole proxy).

19.3 Thresholds & escalation (defaults)

Metric	Green	Amber	Red	Notes / Actions
Agreement (per-overlap, commuting)	≥ 0.98	0.95–0.98	< 0.95	On Amber: enforce commuting-only schedule; check ledger/SBS; on Red: serialize & open incident.
Fleet Disagreement KPI (1–mean agreement)	≤ 0.08	0.08–0.15	> 0.15	Fleet-level KPI used in Ch.14; mirrors real traffic.
PVR	< 0.5%	0.5–1.5%	> 1.5%	On Amber: tighten Ô preflight; on Red: freeze non-commuting tools.
TER	≤ 1.0%	1–2%	> 2%	On Red: mis-exec playbook (increase timeouts, widen τ cadence).
Collision Rate (memory/tools/attention)	< 0.5% / < 1% / ~ 0%	×2 of green	> 2% / > 4% / > 0%	Use queueing over eviction for attention; prefer PRI for tools.
Occupancy	40–85%	85–95%	> 95% (≥ 30s)	On Red: back-pressure Ô (raise Δτ), increase pool $N$ , or switch policy LRU→PRI.
$S_c$ (normalized)	0.45–0.85	< 0.45 (2 ticks)	< 0.35 w/ sat↑	Black-hole guard: “Entropy floor” rule.
AL (relative)	≤ 90th pct (persist < W)	> 90th pct (≥ W)	> 95th pct (≥ 2W)	Use quantile bands per domain; high AL without reward lift ⇒ explore.

19.4 Emitters & events (schema)

Per tick (subset):

{
  "tau": 1042,
  "metrics": {
    "AL": 0.72,
    "Sc": 1.38,
    "agreement": {"k": 714, "n": 720, "wilson": [0.98, 0.99]},
    "pvr": {"k": 1, "n": 200, "wilson": [0.00, 0.02]},
    "ter": {"k": 3, "n": 420, "wilson": [0.00, 0.02]},
    "slots": {
      "memory": {"occ": 0.78, "collisions": {"k": 1, "n": 220}},
      "tools":  {"occ": 0.63, "collisions": {"k": 2, "n": 310}},
      "attention":{"occ": 0.33, "collisions": {"k": 0, "n": 90}}
    }
  }
}

Slot events (Slots.Alloc/Release/Evict/Collision/QueueEnter/Exit) must link back to $(τ,\text{channel})$ for auditability.

19.5 Worked example (Support RAG mini-run)

A/B replicas run identical toolsets with commuting reads first and a shared ledger. Agreement on the pointer support.answer tracks near 0.94–0.99 in steady state when redundancy is high; disabling the ledger or adding a non-commuting step degrades it—exactly what agree(·) surfaces.
Slot policy: tools.capacity=4, policy=PRI keeps tail latency down for db.get, while memory.capacity=8, policy=LRU improves hit-rate; watch collisions and P95 waits against SLA bands.
Mis-exec spike playbook: if TER > 2% for 5 min → freeze code.exec, prefer read-only, widen τ by 10%, enable bounded retries.

19.6 Tests

Agreement harness: synth commuting vs non-commuting pairs; verify score and NCE behavior; require Wilson-CI lower bound ≥ threshold to pass.
Mis-exec unit tests: inject invalid preconditions; ensure PVR increments; retries don’t mutate latched trace (τ+1 only).
Slots: non-overlap, eviction accounting, queue drain; assert pool-level SLAs (collision rate, P95 wait) within bands.
SMFT signals: force AL↑, $S_c$ ↓ scenarios; trigger “Entropy floor” guard when coupled with saturation rise.

19.7 Artifacts

API sketch: GET /metrics/micro?window=ticks:128 → {AL, S_c, Agreement, PVR, TER, Slots*} (with Wilson CIs for proportions).
Dash panel: “Micro Five” with sparklines + CI ribbons + bands.
Policy YAML: pool SLAs (collision targets, P95 wait), agreement thresholds, mis-exec alerts—mirrors Ch.4/Ch.14 templates.

19.8 Operator guidance

Design for commutation, externalize records, then measure redundancy—that’s how you raise Agreement.
Treat slots as first-class: queues beat unsafe eviction; back-pressure Ô when Red.
Watch $S_c$ with saturation to avoid semantic black-holes; rotate channels or soften curvature when the floor rule fires.

Next: Chapter 20 — Meso Metrics (ρ, Δτ, Phase-Risk, CWA Score) connects these per-agent signals to fleet-level stability and certified pooling.

Chapter 20 — Meso Metrics

Goal

Measure coordination and pooling safety across agents: Tick Sync $ρ$ , Ô-Desynchrony $Δτ$ , Phase-Risk Index (PRI), and CWA Score—with test batteries (permute / sign-flip / chunk-shuffle), confidence bounds, drift tests, and policy gates that shape scheduling and pooling in production.

What you’ll implement (checklist)

Streaming estimators for ρ (Kuramoto order) and Δτ (tick skew) with anchors & resync policy.
Certificate plumbing for CWA score + PRI, including CI and drift summaries.
Test batteries: shuffle sets, sign-flip panels, chunk-shuffle; stability under perturbations.
Green/Amber/Red bands + degradations (D0…D3) tied to scheduler Ô and pooling choices.
Events/API: TickAnchor, DesyncAlert, /pool certificate payloads exported to telemetry.

20.1 Definitions (operational)

Tick Sync $ρ$ — Kuramoto order parameter

For N observers with tick phases $θ_j \in [0,2π)$ ,

ρ \;=\; \Big|\frac{1}{N}\sum_{j=1}^N e^{i\,θ_j}\Big| \in [0,1] \quad \text{(1 = perfect sync, 0 = uniform desync).}

We derive $θ_j$ from each agent’s cadence-normalized tick phase. Use periodic TickAnchor broadcasts so agents slew (no jumps) toward anchors before computing $ρ$ .

Ô-Desynchrony $Δτ$

Fleet tick skew: max index gap (or p95–p5) across agents; per-agent $\Delta τ_i = τ_i - \bar τ$ . Track as a scalar (fleet) and as a tagged distribution (tenants/pools).

Phase-Risk Index (PRI)

Risk that order/phase still matters after projection $P(\cdot)$ . Two complementary forms are supported:

Spectral / reversal PRI: $\mathrm{PRI}=\max(\mathrm{PRI}_{\text{spec}}, \mathrm{PRI}_{\text{rev}})$ using periodogram mass off DC and reversal sensitivity of the additive pool. Lower is safer.
Panel-derived PRI′: $\mathrm{PRI}'=1-\min(s_{\text{perm}}, s_{\text{flip}}, s_{\text{chunk}})$ , reported by the certificate evaluator. Both correlate; engines may emit either (or both).

CWA Score (Collapse-Without-Alignment certificate)

Aggregate stability of the additive pool under three perturbation panels: permutation (order), sign-flip (orientation), chunk-shuffle (boundaries). Each panel yields $s\in[0,1]$ ; the weighted average is the CWA score. Certificate payload includes per-panel deltas, CI, and drift stats; consumers gate mean/sum pooling on score and PRI.

20.2 Estimators & drift

Windows & smoothing. Compute $ρ$ and $Δτ$ over sliding time windows (e.g., 5–10 s), plus tick windows for fine control. Use EWMA on both for stable alerts. Anchors: broadcast TickAnchor{τ_anchor, wallclock} periodically (0.5–5 s); agents slew local timers; never jump ticks.

Certificate CI & drift. For CWA score, bootstrap panel deltas → 95% CI; keep a rolling reference window and report drift p-values. Include seeds and panel counts in the log for reproducibility.

Stability under perturbations. Run K perturbations per panel (typ. 8–32) and summarize median stability. Maintain component trends (perm vs flip vs chunk) to localize why CWA fails.

20.3 Thresholds & policy actions (defaults)

Metric	Green	Amber	Red	Primary actions
ρ	≥ 0.90	0.80–0.90	< 0.80	Amber→ enter D1 (widen cadence 10–25%); Red→ D2 + restrict schedules to commuting-safe channels; Resync until recovered.
Δτ (ticks)	≤ 2	3–5	> 5	Trim fast outliers, slow cadence, anchor more often; unblock when Δτ ≤ 2.
PRI / PRI′	≤ 0.20	0.20–0.50	> 0.50	If Amber: run full panels, lower K but keep gating; Red: force order-aware pooling. (APIs expose `pri_threshold`.)
CWA score	≥ θ_pass (norm=0.82)	θ_warn–θ_pass (warn≈0.75)	< θ_warn	Pass→ mean/sum; Amber→ consider order-aware trial; Red→ fallback. In Strict mode (D2), raise θ_pass (e.g., 0.98).

Degradation ladder. D0 Normal → D1 Gentle (cadence↑, panels÷2) → D2 Strict (commuting-only; CWA θ_strict) → D3 Quiescent (pause ticks except health). Entry/exit are keyed to $ρ$ , $Δτ$ , occupancy and collision SLOs.

20.4 Test batteries (how to run)

Permutation (shuffle sets). Resample K random permutations; pool; measure distance to baseline pool; compute stability $s_{\text{perm}}=1-\mathrm{median}(\delta)$ .

Sign-flip panels. Apply Rademacher masks per item (and/or per PCA axis); pool; $s_{\text{flip}}$ as above. Flags “SignSensitive” if low.

Chunk-shuffle. Jitter boundaries ±ε, merge/split neighbors; re-project then pool; $s_{\text{chunk}}$ indicates boundary sensitivity.

Stability under perturbations (end-to-end). While running the panels, vary cadence within bounds and inject controlled anchor jitter; ρ should remain ≥ 0.9 and $Δτ$ ≤ 2; certificate stability should not degrade materially if pooling is truly additive. Record CI and drift for the certificate.

20.5 Worked example (fleet resync + certificate gating)

Scenario. Multi-robot field run drifts due to poor time sync: $ρ=0.77$ , $Δτ=7$ . System broadcasts RESYNC anchors each 500 ms, trims fast outliers, widens cadence to 110 ms. Within 12 s $ρ=0.92$ , $Δτ=2$ → reopen full schedules. During D2 Strict, CWA raises θ_pass; a RAG batch with PRI=0.47 and CWA=0.86 fails fast-path and falls back to attention pooling, within the fallback latency SLO.

20.6 Events & APIs

Events (Tick & Sync).
TickAnchor{τ_anchor, wallclock, cadence_ms}, DesyncAlert{rho, delta_tau, level}, Cadence.Update{cadence_ms, reason}, Degrade.Enter/Exit{mode, reason}.

Pooling API (with certificate).
POST /pool returns {cwa:{score, components, ci95, drift}, pri, risk_flags, latency_ms}. Consumers gate on min_score and pri_threshold, with seeds and panel counts logged for audit.

20.7 Operator guidance

Use anchors liberally: keep $ρ≥0.9$ at governance checkpoints; restrict schedules to commuting-safe reads during resync.
Gate pooling by both score and PRI: low score or high PRI → order-aware estimator; store certificate artifacts.
Raise thresholds in stress (D2): stricter θ for CWA and lower $ρ_{\min}$ tolerance reduce cascading failures.

Next: Chapter 21 — Macro Metrics (PBHL Residual, Gap/Flux/Twist, EEI/SI) stitches these meso signals into belt-level closure and controllers.

Chapter 21 — Macro Metrics

Goal

Make program-level closure measurable and controllable. Define PBHL Residual, Gap/Flux/Twist (with coupling α), and EEI/SI; then show how Flux-gate (fast) and Twist-step (slow) controllers keep Residual in band and operate within stability regions.

21.1 Worldsheet metrics (definitions)

PBHL identity (ops layer).

\textbf{Gap}\;\approx\;\textbf{Flux}\;+\;\alpha\,\textbf{Twist},\qquad \textbf{Residual}\;=\;\big|\text{Gap}-(\text{Flux}+\alpha\,\text{Twist})\big|

A belt is the worldsheet swept by a program loop (plan→design→build→validate→deploy→plan). Residual is the closure error to minimize.

Gap(t). Remaining target shortfall projected to governing KPIs; normalize by $\text{Gap}_0$ for comparability (0–1 scale).

Flux(t). Effective throughput (validated increments × impact weights × survival rate), usually an EWMA per cadence.

Twist(t). Rate of structural change that perturbs the plan↔do map; combine proxies like ownership churn, plan drift, and architecture churn, normalized to $[0,1]$ .

α(t). Coupling from Twist to effective progress (signed). Estimate via ridge regression on a rolling window of $\Delta\text{Gap} = -\text{Flux} - \alpha\,\text{Twist} + \epsilon$ . Track CI/variance; gate twist if unstable.

Residual bands (defaults). Green ≤ 0.05, Amber (0.05–0.10], Red > 0.10–0.20 depending on risk tier. Use Five-Line KPI: Gap, Flux, Twist, Coherence/Sync $ρ$ , Residual.

Derived indices.

EEI (Effectiveness/Execution Index) $=\frac{\text{Flux}}{\text{Flux}+\text{Waste}}$ , where Waste = rework + abandoned + blocked. (0–1; ↑ better.)
SI (Sustainability Index) $= ρ\cdot e^{-\lambda_T \max(0,\text{Twist}-\theta_T)}$ , penalizing excessive twist and low sync. (0–1.)

21.2 Estimation & telemetry

Windowing. Daily points with $W\approx 2$ weeks and EWMA $β=0.3$ for dashboard smoothness; retain raw cadence data for audits.
α estimation. Ridge on $(\text{Flux},\text{Twist})$ → $[\beta_F,\beta_T]$ ; set $\alpha \leftarrow \beta_T$ . Emit CI; if CI width > policy, freeze Twist steps.
API. POST /belt ingests Gap/Flux/Twist/α and returns Residual, suggested controls, and indices; GET /belt/:id/kpi exports KPI time series (JSONL/Parquet) with lineage.
Evidence. Each release archives PBHL/4π/gluing checks and KPI rows in an evidence_vault with a bundle hash for audits.

21.3 Controllers & stability regions

Flux-gate (fast; minutes→days).
PI-style action that changes how hard the belt pushes (slots, cadence, staffing, batching). Example:

u_F(t)=k_P\,\text{sgn}(e_R)\,\min(|e_R|,u_{\max})+k_I\!\int e_R\,dt,\quad e_R=\text{Residual}-\varepsilon_g

Map $u_F$ to slot capacity deltas, Ô cooldowns, and priority queues. Stable when (i) Residual dynamics are monotone around the setpoint, (ii) $|k_P|$ respects actuation latency, and (iii) Twist is within budget (no moving target).

Twist-step (slow; weeks).
Hysteretic, budget-bound policy that freezes/unfreezes refactors and ownership changes. Trigger only when $|\text{Residual}|>\varepsilon_a$ and $\alpha$ has sign/CI confidence; guard step size $|\Delta\text{Twist}|\le\tau_{\max}$ per review period. Stability improves when 4π periodicity and gluing audits pass (consistent framing & modular joins).

Stability region sketch.
Operate in a two-timescale band where: (a) certificate/sync are healthy (ρ≥0.9), (b) Flux-gate reaches steady state within ≤2 review windows for small Residual perturbations, (c) Twist-step period ≥4 Flux-gate time constants, and (d) α variance below policy. Outside this region, degrade (D1→D3) and/or freeze twist.

21.4 Thresholds & gates (defaults)

Residual gates. Gate-R: if Residual > ε_red for 2 windows → freeze non-critical twist, raise Flux-gate. Gate-α: if α variance spikes → executive review required.
EEI/SI SLOs. Alert on EEI drop >10% w/w or SI < 0.7 for 2 weeks; investigate Waste components and sync.
Release gate (audit). Require PBHL green, 4π pass, gluing pass; block on any red. SQL templates provided in PFBT Appendix G.

21.5 Worked examples

A) Positive closure. Start: Gap=0.80, Flux=0.15, Twist=0.05, α≈+0.20 → Residual≈0.64 (red). Flux-gate raises tool capacity and relaxes a cooldown; keep twist frozen. After 2 weeks Flux→0.32, Twist→0.04, α≈+0.18 → Residual≈0.47 (amber). Then a targeted refactor (Twist 0.06, α>0) drops Residual to ≈0.29 (green trajectory).

B) Twist spike incident. Reorg injects Twist=0.20; α flips negative (−0.10). Residual jumps to 0.35 (red). Gate-R freezes refactors 14 days, boosts Flux-gate, and schedules α review. Recovery as Twist decays and α stabilizes.

21.6 Tests & audits

PBHL Closure Audit. Enforce $|\text{Gap}-(\text{Flux}+\alpha\,\text{Twist})| \le \tau_{\text{PBHL}}$ .
4π periodicity. Class-function invariants equal at 0 and $4\pi$ , differ at $2\pi$ .
Gluing. Interior edges cancel ≤ tolerance in tiled belts.
Controller regression. Simulate vanity velocity (Flux↑ without validation): EEI↓ and Residual mismatch—controller should refuse release. Simulate frequent reorgs (Twist↑ with α<0): Twist-step must throttle.

21.7 Artifacts

API. /belt update + control suggestions; KPI export with lineage (pool/agreement/cert refs).
Dashboard. Five-Line KPI: banded Gap vs Flux+α·Twist, Residual line, Twist with α overlay, ρ mini-panel, EEI/SI sparklines, active gates.
Runbooks & SQL. Release gate queries, twist-budget window checks, evidence_vault schema.

Operator guidance

Drive Residual, not vanity throughput. Flux must be validated; pair with EEI to detect waste.
Guard α. Don’t twist without a confident α; freeze when variance widens.
Stay in the stability region. Keep ρ high, separate timescales (fast Flux-gate, slow Twist-step), and pass 4π+gluing before big steps.

Next: Chapter 22 — Telemetry Surfaces (dashboards, exports, evidence & privacy).

Chapter 22 — Telemetry Surfaces

Goal

Ship operator-first telemetry surfaces that make ObserverOps observable and auditable: dashboards (micro→meso→macro), signed exports (traces, cert logs, belt KPIs), and governance-ready evidence with SOC/ISO-friendly mappings. Also lock down data retention, privacy redaction, and lineage.

What you’ll implement (checklist)

Dashboards: Micro “Micro Five”, Meso sync/cert panels, Macro Five-Line KPI with Residual bands and gate overlays.
Exports: Signed, hash-addressed bundles with KPI, Gate.Decision, and Cert Logs, plus lineage.
APIs/Webhooks: /belt updates, KPI export, signed Gate.Decision webhooks.
Privacy/Retention: PII tagging & redaction maps, hot/cold retention, tamper evidence.
Evidence Vault: periodic exports to GRC vault with lag alerts and completeness checks.

22.1 Dashboards (panels you’ll ship)

A. Micro (agent-level)

Micro Five: AL, $S_c$ , Agreement, Mis-exec (PVR/TER), Slots (occ/collisions) with bands & Wilson CIs. Feed from Observer Runtime & Slot Allocator SLOs.

B. Meso (fleet & certificates)

Sync Panel: $ρ$ sparkline, $Δτ$ distribution, anchor cadence, desync alerts.
Certificate Panel: CWA score and components (perm/flip/chunk), PRI histogram, drift p-values; show fallback rate.

C. Macro (BeltOps)

Five-Line KPI: Gap, Flux, Twist, Coherence (e.g., agreement), Residual with Green/Amber/Red bands; overlay gate states and Twist annotations. Panel JSON carries band thresholds.
Board One-Pager: EEI, SI, Residual band, cert pass-rate, PRI p95, incidents/actions—ready for execs.

Operator note: Dash panels must overlay policy gates decisions and cadence changes; this ties telemetry to control.

22.2 Exports & the Evidence Vault

Bundle format. Periodic (e.g., every 15 min) signed bundles with a manifest referencing time-sliced files; all artifacts are hash-addressed and carry lineage.

Manifest (essentials):

kpi.parquet — Gap/Flux/Twist/Coherence/Residual, EEI/SI.
decisions.jsonl — Gate.Decision with reasons & actions.
cert_logs.parquet — referenced CWA certificates (subset).
lineage — pool_ids, agree_ids, cert_refs.
signature — ed25519/HMAC; verify on ingest.

SOP-C (export): validate signatures + manifest completeness; cross-check counts vs telemetry; push to GRC vault; alert on export lag > 2 min.

APIs:

POST /belt → computes PBHL residual, returns KPIs/indices; use update_id for lineage.
GET /belt/:id/kpi?...&format=parquet|jsonl → time-series export with lineage.

22.3 Webhooks & decision logs

Register a signed webhook for Gate.Decision, Belt.Update, CWA.Drift. Payloads include reasons (e.g., cwa_warn_or_pri, residual_amber) and actions (cadence_factor, panel_scale, commuting_only). Verify via X-ObserverOps-Signature.

Why this matters: closing the loop (Data→Macro→Control) is explicit in the telemetry: Belt updates feed gates; gates feed Tick & Sync; all changes are logged and visible in panels.

22.4 SOC/ISO-friendly mappings (what evidence you emit)

Immutable traces & cert logs → append-only, hash-chained stores with signed exports (maps to auditability & change evidence).
Deterministic gates → versioned thresholds, signed decisions, override/waiver workflow (controls + change management).
Lineage on KPIs → pool/agreement/certificate refs embedded in exports (end-to-end evidence).
GRC handoff → scheduled export to vault; pass/fail metrics like Audit pass-rate tracked on the dashboard.

See also Appendix “Safety & Compliance Mapping — SOC/ISO control matrices & trace evidence” for control-by-control checklists.

22.5 Data retention, privacy & lineage

Retention: hot 90–365 days, cold 7 years; publish retention in manifest; export redaction maps alongside data.

Privacy & minimization:

Tag projection artifacts with PII/secret flags; redact raw content from Cert Logs; store vectors with lineage only.
Hash actor IDs with keyed salt; enforce k-anonymity ≥ 5 in published bins; log access to Twist entries (often sensitive).

Tamper evidence: trace & cert hash-chains; reproducible panel seeds; signed bundles.

Lineage contracts: link KPI rows to pool/agreement/cert IDs; enforce no orphan events and exact interior-edge cancellation in belt tiling (gluing).

22.6 SLOs, alerts, and safe modes (telemetry-backed)

SLOs: Measure→write p95 ≤ 50 ms; /agree p95 ≤ 40 ms; export lag p95 ≤ 2 s; sync/status broadcasts ≤ 10 ms. Panels show banded tiles.
Alerts: LatchingViolation, CWA.Red or Drift, Sync.Red (ρ<0.8 or Δτ>5), ledger ingestion lag. Each alert links to evidence IDs.
Safe modes (visible on panels): CWA-off, Ô-reduced (commuting-only), Tick slow-roll, Read-only audit—with clear exit criteria and gate overlays.

22.7 Artifacts

Panel specs: JSON for Five-Line KPI with bands; Meso sync & cert components.
Webhook schema: signed Gate.Decision payloads + retry policy.
Export manifest template: KPI/Decisions/Cert Logs + lineage + signature.
Security hooks: auth scopes per plane; least-privilege runners; privacy map file.

Operator guidance

Make control visible. Overlay gate states & cadence changes on every relevant panel—operators should see why the system throttled or fell back.
Ship lineage, not screenshots. Every KPI point must be traceable to pool/agreement/cert IDs; exports are the ground truth for audits.
Respect retention & redaction. Keep hot/cold windows and publish privacy maps; never ship raw PII in cert logs.

Next: Part V — Guarantees & Proof Sketches (Ch. 23–27) ties these surfaces back to the math.

Part V — Guarantees & Proof Sketches

Chapter 23 — Internal Collapse

Claim (what we guarantee)

Latching is a fixed point under the observer’s own past; once a record is committed at tick $τ_k$ , it is in-frame irreversible, and all downstream control must branch on it. Formally, let $\mathcal{F}_{\le τ}$ be the σ-algebra generated by the committed trace up to $τ$ . For the tick- $k$ outcome $Y_k$ written to the trace, internal collapse requires

\mathbb{E}[Y_k \mid \mathcal{F}_{\le τ_k}] \equiv Y_k

and all future scheduling/control be measurable w.r.t. $\mathcal{F}_{\le τ_k}$ (no dependence on hypothetical retro-edits).

23.1 Formalization (fixed points & branching)

Filtration view. The observer’s trace induces an increasing filtration $\mathcal{F}_0\subset\mathcal{F}_1\subset\cdots\subset \mathcal{F}_{\le τ}$ . Conditional expectation onto $\mathcal{F}_{\le τ_k}$ yields delta-certainty for events already written: they are fixed points of the projection.
Operator-algebraic restatement. With memory algebra $\mathcal{M}$ and world algebra $\mathcal{W}$ , the conditional expectation $E_{\le k}:\mathcal{W}\!\otimes\!\mathcal{M}\to\mathcal{F}_{\le τ_k}$ satisfies $E_{\le k}(A)=A$ for any past event $A\in\mathcal{F}_{\le τ_k}$ : observer-specific certainty is algebraic latching.

23.2 Implementation invariants (what the runtime must enforce)

A commit is measure→append→advance; advancing $τ$ is the latch. Enforce with a latching guard:

Monotone $τ$ . Advance only on successful append; never on attempt.
Hash-chain. Each record carries prev_hash and hash(H(prev, τ, channel, outcome, meta)) for tamper-evidence.
Append-only. No UPDATE to past ticks; corrections are new records (e.g., kind:"correction").
Idempotency. Duplicate submits (same idempotency_key, $τ$ ) return the prior commit.
Atomicity. If append fails, $τ$ does not advance.

Branch measurability hook. The scheduler $\hat O$ must read only committed $T$ (post-append), ensuring downstream decisions are measurable w.r.t. $\mathcal{F}_{\le τ_k}$ .

23.3 Proof sketch (why latching yields in-frame irreversibility)

Write ⇒ fixed point. Once $(τ_k,π_k,y_k)$ is appended, the event “ $Y_k=y_k$ ” lies in $\mathcal{F}_{\le τ_k}$ . Conditional expectation onto $\mathcal{F}_{\le τ_k}$ leaves it invariant: $\mathbb{E}[Y_k \mid \mathcal{F}_{\le τ_k}] = y_k$ . This is the algebraic form of “delta-certainty”.
Control measurability. Post-commit policies $f(S,T_{\le τ_k})$ are $\mathcal{F}_{\le τ_k}$ -measurable, so downstream branches cannot depend on counterfactual edits of $T_{<τ_k}$ . Any “edit” appears only as new information at $τ_{k+1}$ .
Runtime guard ⇒ no retro-edit. The hash-chain + append-only schema forbids in-place mutation; all alternative paths require a new tick (a new branch), preserving in-frame irreversibility operationally.

23.4 Limits & failure modes (and the guards you ship)

External overwrite. An out-of-band process mutates history (e.g., a “cleaner”). Guard: append-only API; verify hash-chain; reject with 409 Conflict; quarantine run if chain breaks.
Re-entrancy. A handler re-enters the loop and writes twice at the same $τ$ . Guard: enforce monotone $τ$ and idempotency keys.
Partial commit. Measurement succeeds but write_trace fails while $τ$ advanced. Guard: atomic transaction boundary; no $τ$ advance on failure.
Policy drift (soft irreversibility). If post-latch the scheduler’s entropy doesn’t drop, branches aren’t conditioning on $T$ . Guard: M3 Branch determinism metric; alert on missing entropy drop.

23.5 Worked examples

Qubit toy (Z↔X). Latching points are the commits; swapping non-commuting instruments changes intermediate distributions, not the fact that each commit is in-frame irreversible.
Tool call (plan→tool→trace). Any “cleanup” of a past tool result must be an append with kind:"correction" at $τ_{k+1}$ ; updates to $τ_k$ are rejected.

23.6 Tests & metrics (proof obligations in CI)

T1 Hash-chain integrity. Recompute all links; first mismatch ⇒ incident + quarantine.
T2 No silent retro-edit. Attempt UPDATE on $τ=k$ ⇒ expect 409; next valid change appears as a new tick.
T3 Idempotent commit. Duplicate (τ,channel,idempotency_key) ⇒ single stored record.
M1 Trace half-life. How long record $k$ influences $\hat O$ .
M2 Latch Latency. Measure end → commit time; bound for real-time.
M3 Branch Determinism. Entropy of $\hat O$ ’s next-channel distribution should drop after latching.

23.7 Artifacts

APIs. POST /measure (optional auto-commit with idempotency_key), GET /trace/:id with range & proof options; error codes 409/412/428 for guardrail violations.
Figure. Ô-first loop with the LATCH point and side-rail hash-chain (see Ch.1 Figures F-1/F-2).
Checklist. “Advance $τ$ only on append; forbid UPDATE; expose correction type; bound latch latency; log seeds & hashes.”

Takeaway. Internal collapse is both math (fixed point under conditional expectation) and ops (append-only, hash-chained, idempotent writes). Together they make branches replayable and audits meaningful.

Chapter 24 — Cross-Observer Agreement

Claim (what we guarantee)

Commuting effects + shared (or redundant) records ⇒ AB-fixedness.
If observers $A,B$ measure aligned channels whose effects commute on the visited support, and both condition on the same pointer information (either a shared ledger or SBS-style redundancy), then they assign delta-certainty to the same effective outcome on those keys (AB-fixedness).

24.1 Objects & pre-conditions

Compatibility/commutation graph $C$ . Edge $(\pi,\pi')\in C$ iff effects commute on the sampled subspace; we only score overlaps on keys $K^\star$ where aligned instruments commute. Frame maps $\phi$ + a canonical labeler $\lambda$ align channels for comparison.
Shared/redundant records. Either (i) shared ledger with hash-chained records (hash match proves sameness), or (ii) SBS redundancy: independent fragments $\{E_r\}_{r=1}^R$ carrying the same pointer value. Redundancy proxies: majority stability & permutation stability.
Latching. Internal collapse guarantees both policies are measurable w.r.t. committed past; no retro-edits inside a tick.

24.2 Formal statement & sketch

Theorem (AB-fixedness, operational form).
Let $K^\star$ be the set of canonical keys with (i) commuting aligned effects $[\pi_A,\pi_B]=0$ , (ii) either a shared trace for those keys or SBS-style redundant fragments accessible to both, and (iii) latched traces. Then for every $(k,τ)\in K^\star$ , the effective outcomes used by $A$ and $B$ coincide almost surely.

Sketch.

Commutation ⇒ order-independence. Joint outcome law on $K^\star$ is invariant to instrument order, removing schedule artifacts.
Shared/SBS record ⇒ common conditioning. Either the same hash-proven record is read by both, or SBS fragments supply the same pointer value with high probability; hence both condition on the same σ-algebra.
Latching ⇒ fixed points. Once written, events are fixed under conditional expectation; downstream policies are $\mathcal F_{\le τ}$ -measurable. Thus the effective values coincide (AB-fixedness).

Algebraic lens. In a common algebra, commuting projections $P_A,P_B$ ensure agreement on their intersection; AB-agreement is “commuting projections in a common algebra” plus shared access to the recorded outcome.

24.3 Error bounds (redundant fragments)

When each SBS fragment independently reports the pointer with error $p<\tfrac12$ , the majority estimator over $R$ fragments has error

\Pr[\text{maj wrong}] \le \exp\!\big(-2R(\tfrac12-p)^2\big)

(by Hoeffding). Thus agreement failure on $K^\star$ decays exponentially in $R$ under independence; with correlations, replace by an effective $R_{\text{eff}}$ via block/bootstrap. (Our redundancy proxies—majority & permutation stability—track this behavior in practice.)

24.4 Counterexamples (why the assumptions matter)

Non-commuting effects. Insert $X$ between $Z$ reads on a qubit; intermediate outcomes need not agree ⇒ no AB-fixedness.
Hidden channel / weak redundancy. One observer applies an unlogged transform or reads fragments carrying no pointer info; consensus need not converge even as $R$ grows.
Bad frame maps. Non-isometric mappings can destroy commutation and common support, fabricating “agreement” or making it impossible.

24.5 Tests, diagnostics, artifacts

agree( $T_A,T_B$ ). Score on commuting overlaps after frame mapping; report non-commuting exposure (NCE), redundancy stats, and hash-match proofs for shared records.
SBS redundancy probes. Majority & permutation stability with thresholds (green ≥ .98, amber .95–.98, red < .95).
Shared-ledger proof. Hash-match ratio over overlaps; any mismatch is actionable.

Operator guidance. Design for commutation, externalize records (or build redundancy), then measure agreement; gate schedules when NCE rises.

Chapter 25 — CWA Validity

Claim (what we guarantee)

Project→add is valid when order/phase wash out; the CWA certificate detects this with high reliability. After per-item projection $P(\cdot)$ , additive pooling (mean/sum) is safe iff the pooled result is stable under perturbations that scramble order, flip orientations, and jitter chunk boundaries; the certificate’s score operationalizes this invariance.

25.1 Setup & statement (operational form)

Let $X=\{x_i\}_{i=1}^N$ , $z_i=P(x_i)\in\mathbb{R}^d$ , baseline additive pool $\mu_0=\frac1N\sum_i z_i$ (or sum). For each panel $j\in\{\text{perm},\text{flip},\text{chunk}\}$ , draw $K$ perturbations $T^{(j)}_k$ and re-pool to $\mu^{(j)}_k$ . Define a normalized stability distance $\delta(\mu^{(j)}_k,\mu_0)$ , combine panel medians into scores $s_j\in[0,1]$ , and aggregate

\mathrm{CWA\_score}=\sum_j w_j\,s_j\in[0,1].

Validity band (examples): Strict: pass if score ≥ 0.98 and PRI ≤ 0.20; Default: pass if score ≥ 0.82 and PRI ≤ 0.50. Otherwise warn/fail and auto-fallback to order-aware pooling.

Panels & rationale.

Permutation (order): detects hidden order sensitivity introduced upstream (e.g., normalization, sequence-conditioned projection). For true additive observables, order shouldn’t move $\mu$ .
Sign-flip (orientation): flips per-item signs (or top-K PCA axes) to test whether arbitrary orientation conventions survive projection; additive observables are sign-consistent in aggregate.
Chunk-shuffle (boundaries): jitters or re-chunks items to probe boundary dependence in the projector; robust collapse erases these effects.

Complement with Phase-Risk Index (PRI) (spectral/reversal gauges) as a fast pre-screen; high PRI flags phase structure where order matters.

25.2 Why this works (collapse geometry → real arithmetic)

SMFT’s collapse geometry says phase-sensitive structure is destroyed by projection; what survives are real, order-insensitive quantities that compose additively (plus simple scalings/roots). Under such collapse, addition is the unique robust macro operation; phase/logical compositions do not survive. CWA simply tests whether the current batch exhibits that post-collapse regime.

25.3 Certificate soundness (informal sketch)

Invariance ⇒ stability. If $P$ removes order/phase and boundary idiosyncrasies, then for all perturbations in the panels, $\delta(\mu^{(j)}_k,\mu_0)$ concentrates near 0 ⇒ $s_j$ near 1 ⇒ score passes. (Mean/sum are intrinsically permutation-invariant; the panels reveal upstream violations.)
Sensitivity to coherence. Coherent/phase-encoded sets (e.g., alternating regimes) produce large reversal or flip deltas; chunk jitter breaks regime alignment ⇒ score drops, PRI rises ⇒ fast-path blocked; order-aware fallback keeps accuracy.
Stats discipline. Use bootstrap CIs on panel deltas and drift tests across windows; publish seeds and component scores so policy gates can set risk-aware thresholds.

Type I/II controls. Increase panel counts $K$ to reduce false green; raise thresholds in Strict modes; log CI and drift to bound decision risk. (Latency/complexity budgets are documented for pass vs fallback.)

25.4 Statistical tests (minimal recipe)

Distance: $\delta(\mu,\mu_0)=\min\!\big(1,\ \|\mu-\mu_0\|_2 / (\|\mu_0\|_2+\varepsilon)\big)$ or a cosine+norm blend; take panel median.
Score: $s_j=1-\mathrm{median}(\delta)$ ; $\mathrm{score}=\sum_j w_j s_j$ . Defaults $w=(0.4,0.3,0.3)$ .
PRI: max of spectral mass off-DC and reversal sensitivity. Gate with $\text{PRI}\le \tau$ before allowing fast-path.

25.5 Limits & counterexamples (why we can fail safely)

Coherent chains. Strongly phase-coded sequences (periodic or alternating regimes) legitimately fail sign-flip/reversal; additive pooling would blur regimes; fallback (attention/CNN/sequence) is required.
Bursty phase. Irregular, bursty coherence can pass small $K$ panels by chance; mitigate with stricter $K$ , lower pass θ, or a Strict profile for high-stakes pools.
Boundary-entangling projectors. If $P$ encodes positional bleed, small chunk jitter reveals instability (low chunk score). Fix the projector or keep fallback.

Note. CWA is a certificate, not a proof for all future batches; we therefore ship drift detection and reproducible seeds to bound exposure.

25.6 Worked evidence (pass/fail archetypes)

Orderless bags (PASS): doc chunks projected with minimal positional bleed → perm/re-chunk stable; CWA ≈ 0.995–0.999; mean pooling safe; latency win.
Alternating regimes (FAIL): time series with phase-encoded features → sign/reversal & chunk panels unstable; score ≈ 0.82, PRI ≈ 0.55; fallback maintains accuracy.

25.7 Artifacts & gates

/pool API returns {score, components, PRI, ci95, drift} with seeds; policy gates choose aggregator (add vs order-aware). SLOs: ~30 ms pass, ~120 ms fallback.
Runtime defaults. Example thresholds and panel counts are provided (perm/flip/chunk $=$ 128/64/32); raise to strict in safety-critical lanes.

Takeaway. CWA makes “just average it” conditional: when projection truly collapses nuisance phase/order, the certificate passes and addition is sound; otherwise, we prove it’s risky and fall back—preserving quality with bounded, explainable latency.

Chapter 26 — Slot Conservation

Claim (what we guarantee)

Capacity is quantized and non-overlapping. Within each typed pool (memory, attention, tools), allocations are integers and occupied addresses are disjoint at every tick; evictions/queueing are explicit policies. From these invariants follow allocator corollaries on collision rates, queue waits, and safe back-pressure.

26.1 Model & invariants

Typed pools & addresses. Partition capacity into slot sets
$\mathcal M=\{m_1,\dots,m_{N_M}\}$ , $\mathcal A=\{a_1,\dots,a_{N_A}\}$ , $\mathcal U=\{u_1,\dots,u_{N_U}\}$ for memory/attention/tools. Allocations request integer units $k$ .

S1 (integrality). $k\in\mathbb Z_{\ge 0}$ .
S2 (non-overlap). At tick $τ$ , occupied addresses in a pool are pairwise disjoint.
S3 (explicit eviction). Freeing capacity occurs only via release() or logged policy eviction—no implicit GC that mutates history.
S4 (observability). Every Alloc/Release/Evict/Collision/QueueEnter/Exit is written to the trace $T$ with provenance.

Runtime contract. Minimal API enforces integer grants, disjoint holds, policy-driven eviction/queueing, and emits events with {pool, k, token, policy, occupancy_after}.

26.2 Why “slots”? (first-principles justification)

Combinatorial closure. LuoShu/HeTu give canonical, balanced discrete capacities: unique integer assignments under global sum/pair constraints; any repeats, gaps, or non-integers violate closure/symmetry. That’s the mathematical archetype behind the “slot” law (quantized addresses, conserved totals along paths).

Operational reading. A “slot” is a discrete, mutually distinguishable capacity for a trace/state at a location—exactly what we enforce for memory/attention/tool pools.

26.3 Sketches (pigeonhole, packing, collisions)

Lemma 1 — Pigeonhole bound (max concurrency)

For a pool with $N$ slots, any set of $N\!+\!1$ simultaneous unit requests cannot be satisfied without eviction or queueing. Reason: By S2 (non-overlap), at most one request occupies a given address; $N$ addresses ⇒ ≤ $N$ concurrent holds. (Equality is achievable with disjoint holds.) Corollary: With integral sizes $k_i$ , feasibility requires $\sum_i k_i \le N$ .

Lemma 2 — Packing & fragmentation

For integral requests, greedy admission is complete when eviction is disallowed: if $\sum k_i \le N$ and arrivals are processed in any order with queueing (no eviction), all items are eventually admitted. (There is no internal fragmentation: addresses are indistinguishable; integrality avoids fractional waste.) Design hint: use strict queueing (policy: NONE) for safety-critical pools (attention).

Lemma 3 — Collision necessity

Define a collision when a request would require evicting an active or unguarded item to admit. If at arrival time $t$ , $\text{free}(t)<k$ and policy prohibits evicting protected grants, then a collision is unavoidable (either refuse or queue). Consequences: (i) collisions upper-bound feasible parallelism under protected leases; (ii) frequent collisions signal either under-provisioning or policy mismatch (e.g., trying to preempt in-flight tools).

Lemma 4 — Queueing vs eviction trade

Let $λ$ be arrival rate (units/tick) and $μ$ the average release rate. In steady state, if $λ>μ$ then either queue length grows (queueing policy) or eviction churn grows (evicting policy). Minimize tail risk by: for tools prefer PRI with preemptible queued items; for attention enforce NONE (no eviction); for memory use LRU to align with locality.

26.4 Allocator corollaries (what you can guarantee)

C1 — Collision-rate bands. With correct policy matching, you can hold

memory collisions < 0.5%, tools < 1%, attention ≈ 0% (by design). Sustained red (>2–4%) indicates mis-sized $N$ or wrong policy.

C2 — Non-overlap unit test. Fill to $k=N$ then request one more ⇒ must queue/refuse (never overlap). This guards S2 at code level.

C3 — Bounded wait SLOs. Set P95 wait ticks: memory ≤ 1, tools ≤ 2, attention 0 (strict). Violations call for back-pressure (increase Δτ, reduce parallelism) before raising $N$ .

C4 — Eviction accounting. Every eviction reduces used by the evicted units, emits Slots.Evict, and links to the causing $(τ,\text{channel})$ . Missing or delayed accounting is a correctness bug.

C5 — Policy-aware Ô. Before selecting a channel $π$ , the scheduler checks can_run(π); if not, it either picks a commuting alternative or inserts back-pressure (Δτ↑). This keeps mis-exec/timeout risk low under load.

26.5 Algorithms & policies (brief)

LRU (memory) for locality; PRI (tools) to protect critical path; NONE (attention) to forbid unsafe preemption. All events are append-only to $T$ ; leases heartbeat and auto-expire. APIs: /slots/request, /slots/heartbeat, /slots/release, /slots/occupancy with p95 SLOs.
Back-pressure hints on refusal: reduce_parallelism, widen_ticks, switch_estimator (e.g., avoid expensive panels). Tie into Tick & Sync degradation modes.

26.6 Worked examples

A) RAG cache (NM=8). LRU vs PRI: LRU maximizes hit-rate under stationary traffic; PRI reserves space for hot topics, reducing tail latency and collisions during spikes.

B) Tool budget (NU=4). With NONE + queueing, bursts smooth (Δτ↑ slightly) and timeouts fall; with PRI, critical db.get preempts web.search, improving P95 latency on the critical path.

26.7 Tests & metrics (CI + ops)

S2 Non-overlap test. Allocate $N$ , then +1 ⇒ expect queue/refuse.
Idempotent release. Releasing more than held caps at held.
Queue drain order. Highest priority admitted first after frees.
Collision rate $=\#\text{Collision}/\#\text{AllocReq}$ with bands: green <0.5% (mem), <1% (tools).
Eviction churn (per wall-time) — high churn ⇒ raise $N$ or swap policy.
Occupancy heatmap — “zebra” pattern flags thrash; “solid band” flags saturation.

26.8 Figures, configs, artifacts

Figure: Slot allocator heatmap (time × slot index; states free/active/idle/evicted).
YAML: Slot policy template (capacities, policies, guard periods, SLA bands).
APIs: /slots/* contracts with decision p95 ≤ 5 ms; /slots/occupancy for dashboards.

26.9 Limits & counterexamples

Hidden allocations. Libraries bypass the allocator → “ghost” collisions; wrap them or they violate S4.
Unsafe preemption. Evicting in-flight tools breaks correctness; mark in-flight as unevictable.
Policy drift. Wrong policy (e.g., PRI for memory) yields thrash (zebra heatmaps) and high churn; correct by switching policy or resizing $N$ .
Non-integral semantics. If a subsystem admits fractional holds, you’ve left the slot model; bring it back behind a slot-ized shim or exclude from SLOs. (LuoShu/HeTu uniqueness relies on integrality.)

Takeaway. Slot conservation is both a combinatorial law (quantized, non-overlapping addresses) and an ops discipline (events, policies, SLOs). Enforce S1–S4 and the allocator corollaries follow—predictable latency, low collision rates, and graceful back-pressure under bursty load.

Chapter 27 — PBHL Closure

Claim (what we guarantee)

For a program belt swept by plan↔do loops, the Purpose-Belt Holonomy Law (PBHL) constrains the belt-integrated variables

\textbf{Gap}\ \approx\ \textbf{Flux}\ +\ \alpha\,\textbf{Twist},\qquad \textbf{Residual}\ =\ \big|\text{Gap}-(\text{Flux}+\alpha\,\text{Twist})\big|

and a two-timescale controller—Flux-gate (fast) and Twist-step (slow)—keeps Residual inside band and operates within explicit stability regions.

27.1 State equation (discrete window model)

Index windows by $n$ . Let $G_n,F_n,T_n,\alpha_n$ be Gap/Flux/Twist/α; Residual $R_n=G_n-(F_n+\alpha_n T_n)$ . A practical evolution (Abelian ops layer) is

G_{n+1} = G_n - \big(F_n+\alpha_nT_n\big) + \eta_n,\qquad R_n = G_n - \big(F_n+\alpha_nT_n\big),

where $\eta_n$ lumps sensing/estimation error and latent flux. PBHL acceptance checks (two-boundary Stokes, gluing, 4π) certify the identity and bound $\eta_n$ .

27.2 Controller (fast–slow)

Fast: Flux-gate. Continuous action $u_F$ that pushes on throughput levers (slots, cadence, routing) with PI(+FF) form:

u_F(n)=k_P\,e_R(n)+k_I\!\sum_{i\le n}e_R(i),\quad e_R(n)=\operatorname{sgn}(R_n)\max(|R_n|-\varepsilon_g,0).

Plant surrogate: $F_{n+1}=F_n + b_F\,u_F(n)+d_F(n)$ with $b_F>0$ . Gains are coherence-weighted to avoid whiplash.

Slow: Twist-step. Discrete, budgeted steps $u_T\in\mathcal{U}$ (reorg, SOP/QA tweak, prompt/policy change) applied hysteretically when $|R|>\varepsilon_a$ and $\alpha$ is sign-stable:

T_{n^+}=T_n+b_T\,u_T,\quad |\Delta T|\le \tau_{\max}\ \text{per review},\ \ \text{freeze if }\text{α-variance high}.

Choose the smallest $u_T$ that reduces $|R|$ ; respect 4π & gluing gates.

α estimation. Ridge on $\Delta G = -F - \alpha T + \epsilon$ over a rolling window; publish CI and freeze Twist if variance widens.

27.3 Linearization & Lyapunov-style sketch

Linearize around an operating point $(G^\star,F^\star,T^\star,\alpha^\star)$ . Small-signal residual

\delta R = \delta G - \delta F - \alpha^\star \delta T - T^\star \delta \alpha.

(i) Fast loop (Twist held fixed). With $\delta T=0,\delta\alpha=0$ , the closed-loop residual under PI satisfies

\delta R_{n+1} \approx (1-b_Fk_P)\,\delta R_n - b_Fk_I\!\sum_{i\le n}\delta R_i + \tilde \eta_n,

which is stable (and drives $\delta R\to$ small band) when $0<k_P<2/b_F$ and $k_I$ chosen under standard discrete-time PI bounds (with anti-windup). Take $V_F=\delta R_n^2+\lambda I_n^2$ as a Lyapunov candidate; $V_F$ decreases for bounded $\tilde\eta$ .

(ii) Slow loop (two-timescale separation). Once the fast loop settles to a residual offset $R^\circ$ (due to latent drift or α-mismatch), a Twist-step chooses $u_T$ minimizing $|R^\circ - \alpha^\star b_T u_T|$ subject to budgets. This yields a monotone drop in $V_T=R^2$ at step instants. Under Tikhonov separation (slow step period $\gg$ fast settling time), the composite $V=V_F+V_T$ decreases until Residual enters the green band.

27.4 Stability regions (operating envelope)

Operate where: (a) fast loop poles inside unit circle $\Rightarrow$ $k_P,k_I$ within PI bounds for observed $b_F$ ; (b) slow loop period $\ge 4$ fast time constants; (c) $|\alpha|$ CI width below policy; (d) coherence in-band (stabilizes gains). Telemetry: Five-Line KPI + SI/EEI and gates (Gate-R, Gate-α).

27.5 Limits & mitigations

α drift. Coupling changes with seasonality or regime shifts ⇒ widen CI, freeze Twist, re-calibrate α (4π audit), and prefer Flux-only mode temporarily.
Delayed sensing. Windowing/ETL lag acts like dead-time; shrink $k_P$ , add feed-forward from FaceEvents, and lengthen the slow period.
Hidden flux. Persistent Residual with good α implies latent $\tilde F$ ; enable a Luenberger-style flux observer and attribute Residuals.
Gluing & 4π failures. If invariants fail on merges or frame flips, block Twist and run diagnostics; only act once checks pass.

27.6 Tests & gates (what CI/ops must pass)

PBHL check: $|\text{Gap}-(\text{Flux}+\alpha\text{Twist})|\le \tau_{\text{PBHL}}$ per window (float64, Kahan on edges).
Fast-loop regression: step-response of Residual decreases to band within ≤2 windows over a synthetic flux bump.
Slow-loop safety: hysteresis + $|\Delta T|\le\tau_{\max}$ ; Gate-α trips on wide CI.
Audits: Stokes, gluing, 4π; freeze Twist on any red; archive evidence bundle.

27.7 Artifacts (you ship)

API. POST /belt → PBHL compute + controller suggestions (u_F,u_T) with bands and α-CI; export KPIs/indices with lineage.
Runbooks. Flux-only incident mode; Twist budget report; change-window checklist (pre/during/post with vault hashes).
Figures. Belt worldsheet & controller loops; stability band overlay.

Takeaway. PBHL turns program control into a disciplined conservation problem. With PI Flux-gates for fast healing, tiny budgeted Twist-steps for slow shaping, and invariant audits (Stokes, gluing, 4π), Residual stays tame—even as α and flux wiggle in the wild.

Chapter 28 — Agent Reliability Suite

Goal

Stress-test an observer (or a small fleet) on synthetic commuting vs non-commuting scenarios, quantify disagreement and mis-exec, and emit scorecards + trace artifacts suitable for CI, dashboards, and audits.

28.1 What you’ll build (checklist)

Fixture generator for instrument pairs: commuting, non-commuting, and mixed (with an explicit commute matrix C).
Replicated runner (A/B[/C]) sharing a ledger; identical Ô policy and tick cadence.
Metrics taps: Agreement on commuting overlaps; Mis-exec split into PVR (policy-violation rate) and TER (tool-error rate); Slot occupancy/collisions.
Scorecards with Wilson CIs + drift summaries; trace bundles (hash-chained).
Ablations: ±Ô, ±slots, ±certificate (expected effect sizes included).

28.2 Fixtures (design)

A. Commuting pair (“readers”)
Examples: kb.retriever.vector ↔ kb.retriever.keyword, read-only sensors, idempotent DB reads. Mark C[k]=true. Expect high agreement when records are shared/redundant (SBS).

B. Non-commuting pair (“mutator+reader” or incompatible bases)
Examples: a state-mutating tool between two reads; or qubit toy $Z$ ↔ $X$ on the same tick. Mark C[k]=false. Expect low agreement on intermediates.

C. Mixed battery
Draw mini-scenarios with a controlled non-commuting exposure (NCE) fraction so you can observe how disagreement tracks NCE.

Slot stress
Run each scenario under (i) nominal slot budgets and (ii) constrained budgets to provoke collisions and back-pressure; verify that allocator invariants (integrality, non-overlap) hold and Ô degrades gracefully.

28.3 Procedure (per scenario)

Seeded setup. Fix seed, set Ô policy, cadence, commute matrix C, slot policy (LRU/PRI/NONE), and enable shared ledger.
Run N ticks on A and B (optional C) with identical inputs; write latched traces (hash-chain). Measure Agreement on commuting overlaps with frame-mapping + lag tolerance.
Record Mis-exec:
- PVR: violations of compatibility/preconditions per tick.
- TER: tool errors/timeouts per tool call.
Slots telemetry: occupancy, Slots.Collision, queue waits; check bands per pool.
Compute CIs: For proportions (Agreement, PVR, TER, CollisionRate), report Wilson 95% CI; attach drift p-values across windows.
Emit artifacts: (a) scorecard.json, (b) trace bundle (A/B/C traces + commute matrix + hash proofs), (c) diff report of conflicts with exact (τ,k) provenance.

28.4 Metrics (definitions & thresholds)

Agreement (commuting overlaps only).
$\mathrm{Agree}=\frac{\#\text{matches}}{\#\text{overlaps}}$ , with NCE tracked separately. Targets: Green ≥ 0.98, Amber 0.95–0.98, Red < 0.95.
PVR (policy-violation rate) and TER (tool-error rate). Targets: PVR < 0.5%, TER ≤ 1.0% (Amber up to 2%).
Slot collisions & waits. Memory < 0.5%, Tools < 1%, Attention ≈ 0%; P95 waits per pool: mem ≤1, tools ≤2, attention 0.
Desync hygiene (optional meso check): $Δτ≤2$ ticks in green; alert ≥3.

28.5 Scorecards (example)

{
  "scenario": "commuting_readers_nominal",
  "seed": 4271,
  "ticks": 5000,
  "agreement": {"score": 0.992, "ci95": [0.989, 0.994], "overlaps": 4217, "nce": 0.002},
  "mis_exec": {"pvr": {"k": 7, "n": 5000, "ci95": [0.0006, 0.0024]},
               "ter": {"k": 33, "n": 3287, "ci95": [0.007, 0.013]}},
  "slots": {"memory": {"collisions": 0.003, "p95_wait": 1},
            "tools":  {"collisions": 0.006, "p95_wait": 2}},
  "alerts": [],
  "artifacts": {"traceA": "blob:sha256:…", "traceB": "blob:sha256:…", "commute_matrix": "cm:v1.12"}
}

For non-commuting fixtures, expect Agreement to drop and NCE to account for it; the scorecard must show why (conflict keys, instrument order).

28.6 Harness (pseudo-CLI)

observerops suite run \
  --scenario commuting-readers \
  --replicas 2 \
  --ticks 5000 \
  --commute-matrix cm:v1.12 \
  --slots-config slots.yaml \
  --seed 4271 \
  --out out/commuting-readers

Outputs:

scorecard.json (per scenario)
traces/ (A/B[/C] JSONL with hash-chains)
agree/ (API responses + conflict diffs)
slots/ (occupancy heatmaps, collision logs)

28.7 Negative controls & ablations (prove signal, not noise)

No-Ô: greedy tool order; expect Disagreement↑ 5–10%, latency↑.
No-slots: unbounded parallelism; expect TER↑/timeouts, Δτ↑, latency variance↑.
No-ledger / weak SBS: remove shared records; Agreement decays; NCE unchanged → proves the role of ledger/redundancy.

28.8 Trace artifacts (auditable by design)

Every run bundles:

Observer traces (append-only, latched, hash-chained).
/agree proofs (hash match ratios, redundancy metrics).
Slot events (Slots.*) with causality links to (τ, channel).
These make CI failures explainable and board-safe.

28.9 Acceptance in CI (defaults)

Commuting suite: Agreement lower-CI ≥ 0.98; PVR < 0.5%; TER ≤ 1%; memory/tools collisions in green; $Δτ≤2$ .
Non-commuting suite: Agreement drops with NCE flagged; runtime must not gate on these overlaps (pass if diagnostics match).
Ablations: observed shifts match Table-of-Effects (±Ô/±slots/±certificate) to catch regressions.

28.10 Worked mini-run (commuting→mixed)

Commuting (vector/keyword/cached): redundancy $R≈3.6$ ; Agreement(A,B)=0.94–0.99; green bands on slots; CI passes.
Mixed (+one mutator): NCE rises; Agreement dips on affected keys; harness labels conflicts with (τ,k) and tool provenance; CI still passes because non-commuting overlaps are excluded from the score.

28.11 Artifacts you ship

Suite config (YAML): Ô, τ, C, slots, seeds, thresholds.
Reference report template: “Reliability Scorecard” with bands and Wilson ribbons.
Example traces & diffs for unit tests and demos.

Takeaway. Reliability isn’t a vibe—it's commuting design + shared records + slots that hold under stress, proven by scorecards you can re-run and audits you can pass.

Chapter 29 — RAG Pooling Battery

Goal

Build a reproducible battery that stresses RAG pipelines on controllable order/phase structure, validates CWA certificates (perm/flip/chunk), and reports accuracy–latency frontiers plus pass/fail ROC curves for certificate thresholds.

29.1 What you’ll build (checklist)

Phase/Order-tunable corpora (bags vs coherent chains; boundary-sensitive text).
Projection→Certificate→Pool harness using /project and /pool with perm/flip/chunk panels + PRI.
Aggregators: fast-path additive mean/sum vs order-aware (attention/CNN) fallback.
Metrics: task accuracy (EM/F1/nDCG@k), latency, CWA score components, PRI, pass-rate.
Reports: accuracy–latency fronts; CWA threshold sweep → ROC (TPR/FPR) against ground-truth “safe-to-add” labels.

29.2 Corpora with controllable phase/order

A. Bag-of-Facts (orderless)
FAQ / glossary snippets split into chunks (uniform policy), minimal positional bleed. Label as order-insensitive (expected CWA pass).

B. Alternating Regimes (phase-coded)
Construct passages where evidence alternates by stance/topic (ABAB…); encode with projector known to retain orientation. Label order-sensitive (expected sign/reversal failures).

C. Boundary-Sensitive Narratives
Long narratives with sentence-aware vs fixed-width chunkers; jitter boundaries ±ε. Label boundary-sensitive (expected chunk-panel hits).

D. Mixed Sets
Blend (A–C) per batch to probe certificate specificity; record per-batch ground truth (safe/unsafe). Use redundancy (e.g., vector+keyword) to stabilize retrieval.

Rationale: CWA predicts project→add is sound when projection erases phase/order, and unsafe when coherence survives; the battery toggles these regimes explicitly.

29.3 Harness (Projection → Certificate → Pool)

Step 1 — Retrieve (commuting set). Vector + keyword channels to the same pointer; dedup with provenance.

Step 2 — Project. /project to produce $V=\{v_i\}$ with policy + meta (seed, dim, chunk policy). SLO p95 ≤ 25 ms.

Step 3 — Certificate. /pool with panels {perm, flip, chunk} and PRI prescreen; log seeds, CI, drift. Defaults: pass≥0.82, warn≈0.75, PRI≤0.50.

Step 4 — Pool. If pass → mean/sum; else → order-aware (attention/CNN/RNN). Latency SLO: pass≈≤30 ms; fallback≈≤120 ms.

Step 5 — Answer & score. Feed pooled rep to generator/reranker; score task metrics; write Cert Log + lineage.

29.4 Test batteries (perm/flip/chunk) & budgets

Use the certificate’s three panels with distances to baseline pool; combine into CWA score and attach PRI. Heuristic panel counts (tunable by latency):
$P=\min(128,\max(32, 8\lceil\log_2(Nd)\rceil))$ , $F=\lfloor P/2\rfloor$ , $C=\max(16,\lfloor P/4\rfloor)$ .

Permutation: order scrambles → stability ⇒ order washed out.
Sign-flip: Rademacher masks or PCA-axis flips → orientation sensitivity.
Chunk-shuffle: jitter/merge/split by chunk_meta.
Aggregate with weights $(0.4,0.3,0.3)$ ; bootstrap CI; log drift.

29.5 Metrics & labels

Accuracy. Retrieval EM/F1/nDCG@k or downstream QA F1; pick per domain. Latency. wall-time user→answer, plus /pool p95. Certificate. score + components + PRI + pass/warn/fail. Pass-rate. share of batches meeting thresholds.

Ground-truth label (safe-to-add). For a batch, define SAFE if additive accuracy is within δ (e.g., 0.5–1.0 F1) of order-aware accuracy; else UNSAFE. Use this to compute ROC as you sweep the certificate pass threshold θ.

29.6 Reports you’ll produce

A. Accuracy–Latency Fronts. Plot additive-pass vs fallback; aim to shift Pareto down/right with better chunking/redundancy. Include pass-rate and panel costs.

B. CWA ROC Curves. Sweep θ (e.g., 0.70→0.99).

TPR: fraction of SAFE batches that pass.
FPR: fraction of UNSAFE batches that pass (false greens).
Add PRI gating variants and strict mode overlays.

C. Component Diagnostics. Perm vs flip vs chunk stability to localize failures; tie to projector/chunker choices.

29.7 Baselines & ablations

Always-add (mean w/o certificate): fast, risk high → expect accuracy drop on phase-coded corpora.
Always-attention (no add): stable accuracy, latency higher.
CWA-gated (ours): near-best accuracy with lower latency when pass-rate is high. Quantify expected lift using the additive-macro theory of CWA.

29.8 Example CLI / outputs

observerops rag-battery run \
  --corpus bag,altregime,boundary \
  --projector embeddings.e5-large \
  --panels perm=128,flip=64,chunk=32 \
  --theta 0.82 --pri_max 0.50 --delta_safe 0.01 \
  --seeds 5 --out out/rag-battery

Artifacts:

frontier.png (accuracy–latency), roc_cwa.png (θ sweep),
scorecards.jsonl (per batch), cert_logs.parquet (panels/PRI/CI/drift),
lineage: projection_id, pool_id, seeds, chunk_meta.

29.9 Acceptance (defaults)

Frontier: CWA-gated within 1–2 pts of always-attention accuracy, with ≥20–40% latency savings on orderless corpora.
ROC: At θ=0.82 & PRI≤0.50, target FPR ≤ 5–10% on phase-coded sets; in Strict (θ=0.98, PRI≤0.20), FPR ≤ 2% for high-stakes lanes.
Pass-rate: steady ≥ 75–85% on bag-like domains (after chunker tuning/redundancy).

29.10 Operator guidance

Treat chunking as instrument design; align boundary policies to reduce chunk sensitivity and raise pass-rate.
Tune panel budgets to your SLO using the provided heuristic; raise to Strict for safety-critical verticals.
Log lineage & seeds; certificate artifacts are audit objects, not debug scraps.

Takeaway. The RAG Pooling Battery turns “should we average these vectors?” into an empirical, per-batch decision—with accuracy–latency curves you can ship and a ROC you can defend.

Chapter 30 — BeltOps Trials

Goal

Simulate initiatives as program belts (OKR loops), perturb Flux and Twist, and verify that PBHL controllers keep Residual in band while improving EEI/SI. Output board-safe scorecards (lift, incidents, time-to-green) plus signed evidence bundles.

30.1 What you’ll build (checklist)

OKR Belt Simulator (discrete windows): generates Gap/Flux/Twist with controllable shocks; estimates α; runs Flux-gate (fast) and Twist-step (slow).
Gates & Incidents: Gate-R, Gate-α, sync/capacity nudges; Residual incident playbook automation.
KPIs & Indices: Five-Line KPI + EEI/SI; acceptance bands and rollups.
Evidence Vault Export: PBHL, 4π, gluing checks + signed KPI/decision logs.

30.2 Design (OKR sims; perturb Flux/Twist; maintain Residual)

Worldsheet model. Each run simulates windows $n=1..N$ with
$G_{n+1}=G_n-(F_n+\alpha_n T_n)+\eta_n$ , Residual $R_n=|G_n-(F_n+\alpha_n T_n)|$ . Controllers act every window; PBHL audits bound $\eta_n$ .

Flux perturbations (“FaceEvents”). Inject positive/negative shocks (unblockers, incidents) and capacity moves. Flux-gate maps control $u_F$ into slot/cadence/priority changes (PI gains as in Ch.21).

Twist perturbations (“TwistFrames”). Apply reframes (scope/ownership/policy). Twist-step uses hysteresis and a rate budget $|\Delta \text{Twist}|\le\tau_{\max}$ . α is re-estimated via ridge on $\Delta G$ vs $(F,T)$ each few windows.

Gates & incidents. Gate-R on Residual red; Gate-α on α-variance; desync/capacity gates may throttle cadence. Residual Incident playbook sequences throttle→rollback→diagnose with exportable snapshots.

Audits per run. Stokes (two-boundary), gluing (interior-edge cancel), 4π periodicity; block releases on any red.

30.3 Procedure (per trial)

Define OKR belt (ID, targets, review cadence, bands). Seed Gap $_0$ , Flux $_0$ , Twist $_0$ , α $_0$ .
Sample shocks: draw Flux shocks (incidents, blockers) and Twist proposals (reorgs, policy edits) with controllable intensity & frequency.
Simulate N windows with PBHL controller on/off (A/B): log $G,F,T,α,ρ,R$ and controller outputs $u_F,u_T$ .
Run gates (CWA/PRI optional), incidents, and playbooks; capture signed Gate.Decision logs.
Audit & export: PBHL residual, gluing histogram, 4π class functions, KPI rows, decisions, lineage → evidence bundle.

30.4 Metrics & outputs

Primary KPIs.

Residual bands (P50/P95; time-in-green), Mean Time to Green (MTTG) after a red event.
EEI (effectiveness/execution) and SI (sustainability) lifts vs baseline (controller-off). Targets: QoQ +10% typical.

Incident analytics. Residual incident rate (#/qtr), Gate-R count, rollbacks, α reviews, false-open/false-close of gates.

Board scorecard (per trial). Current EEI/SI, Residual band & α, audit pass-rate, incidents & actions—matching the belt board one-pager.

30.5 Bench setups (scenarios you’ll ship)

S1 Positive closure (low shocks): verify Flux-gate alone shrinks Residual to green; measure EEI lift without Twist changes.
S2 Twist spike (reorg): α flips or widens CI; Gate-R fires; Twist-step freezes and recovers; report MTTG and SI dip/recovery.
S3 Governance belt (compliance vs growth): couple product & governance belts; perturb policy tests; ArbitrationBelt decisions appear in logs.

30.6 Reports (what you publish)

EEI/SI lift plot (controller-off vs on) with confidence bands.
Residual maintenance chart: bands, incidents, Gate-R/α markers, MTTG annotations.
Audit panel: PBHL residual histogram, gluing residuals, 4π check; all green required for “release OK”.

30.7 Acceptance (defaults)

PBHL: $|R|$ ≤ ε_g 70%+ of windows, P95 ≤ ε_a; audits pass (gluing ≤ τ_glue; 4π ok).
EEI/SI: ≥ +10% EEI and SI ≥ 0.70 sustained 2 weeks after a red event.
Incidents: Residual red MTTG ≤ 2 review windows; incident rate trending down run-over-run.

30.8 CLI (example) & artifacts

observerops beltopstrials run \
  --belt-id ai-helpdesk-2025Q4 \
  --windows 84 --seed 42 \
  --flux-shocks "rate=0.25,scale=0.12" \
  --twist-proposals "rate=0.10,scale=0.06,limit=0.02/wk" \
  --controllers "flux_gate=on,twist_step=on" \
  --gates "R,alpha,rho" --export out/helpdesk-q4

Artifacts:

kpi.parquet (Gap/Flux/Twist/ρ/Residual), decisions.jsonl (Gate.*), audit.pbhl.json (PBHL/gluing/4π), board_onepager.md, signed manifest—ready for GRC.

30.9 Operator guidance

Drive Residual, not raw velocity—EEI guards against vanity Flux; keep evidence exports green.
Budget Twist—freeze when α is uncertain; small, infrequent steps stabilize SI.
Always ship audits—PBHL + gluing + 4π make results defendable in review and regulatory contexts.

Takeaway. BeltOps Trials turn PBHL from a slogan into numbers: you perturb Flux/Twist, controllers keep Residual tame, and EEI/SI climb—backed by audits you can sign.

Chapter 31 — Adversarial & Stress

Goal

Probe ObserverOps under worst-case conditions—coherent sequences, feedback loops, and saturation forcing—and verify graceful degradation (safe-mode transitions) and recovery time back to green bands.

31.1 What you’ll build (checklist)

Adversary generators: phase-coded/coherent inputs; closed-loop perturbations that induce scheduling thrash; bursty load for allocator saturation.
Degradation harness: exercises D0→D3 safe states and back, with Tick & Sync anchors and gate actions wired.
Scorecards: recovery times (TTG/MTTG), number/duration of safe-mode episodes, incident counts, and evidence bundles (traces, cert logs, gate decisions).

31.2 Adversaries (design)

A) Coherent sequences (CWA breaker).
Construct alternating-regime batches (ABAB…) or phase-encoded time series so order/orientation survives projection. Expect low sign/reversal stability, high PRI, and forced fallback. This validates certificate sensitivity.

B) Feedback loops (Ô thrash).
Close the loop from outputs→context so each answer perturbs the semantic field and flips the next channel choice. Drive oscillatory $S_c$ and AL behavior to test scheduling stability and latching discipline under re-entry pressure. Use Control→Data feedback path to throttle when gates fire.

C) Saturation forcing (allocator & sync).
Burst tool calls to push pools beyond 0.9 occupancy; provoke Slots.Collision, grant-latency inflation, and desync ( $ρ↓,\,Δτ↑$ ). Expect entry into D1/D2/D3 and measured recovery with anchors and narrowed schedules.

D) Semantic black-hole drill (field lock-in).
Warp the field toward a dominant attractor (high AL, falling $S_c$ ) and verify entropy-floor guards and exploratory nudges prevent collapse lock-in.

31.3 Procedure (per scenario)

Seed & configure. Set Ô policy, cadence, slot policies, certificate thresholds, and degradation bands; enable shared ledger.
Run N windows/ticks while streaming adversary inputs (A–D). Emit /project→/pool cert logs (with seeds/PRI) and all Tick/Slot events.
Allow gates to act. On sync/capacity or certificate risk, policy gates throttle/block; Tick & Sync widens cadence, restricts to commuting-safe, or pauses. Log Degrade.Enter/Exit.
Recover. Maintain anchors until $ρ≥0.9$ , $Δτ≤2$ , occupancy<0.7 for ≥30 s; reopen schedules and return to D0.
Export evidence. Bundle traces, cert logs, gate decisions for audit.

31.4 Metrics & outputs

Recovery time to green (TTG / MTTG): time from first Red to band recovery (micro: per metric; macro: Residual). Report distribution and p95.
Safe-mode transitions: counts and dwell times in D1/D2/D3; exit criteria met (ρ/Δτ/occupancy).
CWA behavior: pass-rate, score components, PRI; fallback rate and added latency under coherent adversaries.
Allocator stress: collision rate, grant p95, occupancy bands, queue waits.
Incidents: Residual incidents, gate actions, rollbacks—linked to evidence IDs.

Scorecard (example fields).
{ scenario, seed, ttg_s, d1_count, d2_count, d3_count, dwell_s:{d1,d2,d3}, cwa:{pass_rate, pri_p95}, slots:{collisions, grant_p95}, sync:{rho_min, dtau_p95}, incidents:{residual, gates} }

31.5 Acceptance (defaults)

Coherent sequences: CWA fails fast (score ≤ θ or PRI>τ) and fallback holds task accuracy within δ while latency stays ≤ fallback SLO. No additive pooling in Red.
Feedback loops: Ô entropy oscillations damp under throttling; latching remains intact (no retro-edits); no re-entrancy violations.
Saturation forcing: automatic D1/D2/D3 entries match thresholds; p95 recovery to D0 within ≤ 60–120 s for configured burst; ρ/Δτ return to green.
Black-hole drill: entropy-floor guard trips only with saturation rise; AL reduces after exploration kick; no long-lived lock-in.

31.6 Worked adversaries

A→FAIL, fallback OK. ABAB sequence: CWA≈0.82, PRI≈0.55 → order-aware pooling engaged; accuracy parity within 1–2 pts; +70–100 ms latency.

C→D2/D3 spiral, then recover. Burst drives mem occupancy to 0.92, collisions 12/min; Gate throttle + commuting-only + anchors q=500 ms → after ~45 s, occupancy 0.74, ρ≥0.9, exit to D0.

31.7 CLI & artifacts

observerops stress run \
  --adversaries coherent,feedback,saturation,blackhole \
  --ticks 20000 --seed 2025 \
  --gates "rho,delta_tau,capacity,cwa" \
  --bands d1=gentle,d2=strict,d3=quiescent \
  --out out/stress-2025Q4

Artifacts:

scorecards.jsonl (TTG, dwell, incidents),
traces/*.jsonl (hash-chained), cert_logs.parquet,
gates/decisions.jsonl + Degrade.Enter/Exit,
signed manifest for GRC vault.

31.8 Operator guidance

Let gates breathe. Don’t pin thresholds; D1→D2→D3 progression stabilizes loops faster than manual firefighting. Exit strictly on ρ/Δτ/occupancy greens.
Treat coherence as a feature, not a bug. If coherent chains are common, keep fallback warm and measure ROC/pass-rate; don’t force add.
Practice lock-in escapes. Run semantic black-hole drills; watch $S_c$ with saturation and nudge exploration to avoid attractor traps.

Takeaway. Under adversaries, ObserverOps should degrade predictably (safe modes) and come back quickly (measurable TTG)—with audit-grade artifacts that show what happened and why.

Chapter 32 — Ablations & A/B

Goal

Quantify what each ObserverOps invariant actually buys you. Run controlled A/B slices—±Ô (scheduler), ±slots (allocator), ±certificate (CWA), ±belts (PBHL controllers)—and report effect sizes with actionable guidance.

32.1 What you’ll build (checklist)

Traffic replayer to feed identical workloads across variants (seeded).
Toggleable stack: Ô on/off, slot allocator on/off, CWA on/off, BeltOps on/off.
Score taps: Agreement/Disagreement, Mis-exec (PVR/TER), Δτ & ρ, Slot collisions, CWA scores/PRI, PBHL Residual & EEI/SI.
Report generator: summary tables with Wilson CIs + drift, plus trace/cert/belt evidence bundles.

32.2 Slices (design)

Run 3× week-long (or K-epoch) A/Bs per slice against the Baseline (Ô+slots+certificate+belts):

No-Ô (greedy order; no compatibility-aware scheduling).
Expect Disagreement↑ 5–10%, latency↑ via conflicts; NCE exposure rises when mutators slip between reads. Guidance: restore commutation-first plans and frame maps.
No-slots (unbounded parallelism; no allocator).
Expect Mis-exec↑ (timeouts), Δτ↑, E2E latency variance↑; collisions become “ghost” errors since no S4 observability. Guidance: re-enable S1–S4 (integrality, non-overlap, explicit eviction, observability).
No-certificate (always add; no CWA).
Expect accuracy↓ on coherent/boundary-sensitive corpora even though latency↓ (skips fallback). Guidance: re-enable /pool certificate (perm/flip/chunk) + PRI gating.
No-belts (disable PBHL controllers; no Flux-gate/Twist-step).
Expect Residual time-in-green↓, MTTG↑ after shocks; EEI/SI drift. Guidance: re-enable PBHL identity Gap≈Flux+α·Twist, with gates and audits (4π, gluing).

32.3 Metrics & effect sizes (what to measure)

Slice	Primary deltas (typical direction)	Why it moves
No-Ô	Disagreement +5–10%; NCE↑; latency↑	Loss of commute-aware order & shared-ledger alignment → AB-fixedness breaks more often.
No-slots	PVR/TER↑; Δτ↑; latency variance↑; collisions untracked	Without S1–S4, contention becomes invisible; bursts cause tool storms & desync.
No-certificate	Accuracy↓ on phase/boundary sets; latency↓	Project→add used where order/phase survive; certificate would have failed and triggered fallback.
No-belts	Residual↑; time-in-green↓; EEI/SI↓; incidents↑	No Flux/Twist control to close Gap; α unmanaged; audits missing.

Definitions & taps:
Agreement on commuting overlaps (with frame mapping + hash proofs); PVR/TER from runtime; Δτ & ρ from Tick & Sync; slot collisions/queues from Slots.*; CWA score & PRI from /pool; PBHL Residual, EEI/SI via /belt.

32.4 Procedure (per slice)

Pin config (commute matrix C, seeds, cadence, slot policy, CWA thresholds, belt bands).
Replay workload to Baseline and Variant; collect traces, cert logs, belt KPIs.
Compute deltas with Wilson CIs; attach drift and per-metric p-values.
Export evidence bundle (hash-addressed manifest; lineage linking pool/agree/cert/belt IDs).

32.5 Example CLI

observerops ablate run \
  --slices noO,noSlots,noCert,noBelts \
  --ticks 100k --seed 2025 \
  --commute-matrix cm:v1.12 \
  --slots-config slots.yaml \
  --cwa "theta=0.82,pri_max=0.50,perm=128,flip=64,chunk=32" \
  --belt "eps_g=0.05,eps_a=0.10" \
  --out out/ablate-2025Q4

Outputs:

effect_sizes.json (per metric with CI),
scorecards/*.json (baseline vs variant),
traces/*.jsonl (hash-chained), cert_logs.parquet, belt/kpi.parquet,
signed manifest.sha256.

32.6 Result template (sample)

{
  "slice": "noCert",
  "accuracy": {"delta": -0.021, "ci95": [-0.028,-0.014]},
  "latency_ms": {"delta": -38, "ci95": [-45,-30]},
  "cwa": {"pass_rate": 0.00, "pri_p95": 0.56},
  "notes": "Coherent chains present; certificate would have failed; fallback protected accuracy."
}

For noÔ: disagreement_delta=+0.067 [0.048,0.086], nce_delta=+0.012.
For noSlots: ter_delta=+0.009, dtau_p95=+3, latency_var_x1.7.
For noBelts: residual_time_in_green=-0.23, eei_delta=-0.08, si_delta=-0.09. (Illustrative.)

32.7 Guidance (what to change when a slice “wins”)

If No-Ô looks “faster” but disagreement/latency variance rise: restore Ô; encode commute matrix & frame maps; keep the shared ledger to recover AB-fixedness.
If No-slots looks “throughput-y”: it’s masking contention. Re-enable S1–S4; use LRU for memory, PRI for tools, NONE for attention; watch collisions & queue P95.
If No-certificate “improves” latency: you’re taking hidden accuracy debt on coherent/boundary sets—turn CWA back on and tune chunking/projector.
If No-belts seems “simpler”: Residual/EEI/SI will drift; re-enable Flux-gate/Twist-step; keep α under audit with 4π & gluing checks.

32.8 Artifacts you ship

Ablation config (YAML) mirroring Ch.14’s template (Ô policy, CWA thresholds, slot pools, belt bands).
Effect-size table (CSV/MD) for board packs.
Evidence bundle: traces + cert logs + belt KPIs + manifest; reproducible seeds & thresholds.

Takeaway. The ablations make the case quantitatively: Ô protects agreement, slots tame contention, certificates prevent unsafe pooling, and belts close the loop. Keep all four on for production—and use this suite to prove it, every release.
