Visibility of circuits and assemblies

1) Task and observation object

• end-to-end causality (click to invoice);
• predictable SLOs and managed risk;
• rapid RCA and low MTTR;
• provability (signed summaries, WORM audit) at minimum telemetry cost.

2) Observability ontology

• `chainId`, `nodeId`, `role`(operator/studio/psp/kyc/affiliate/stream), `jurisdiction`, `env`(prod/stage/sbx), `traceId`, `spanId`, `routeId`, `campaignId`, `tableId`, `apmRouteId`.

• `click`, `session_start`, `registration`, `kyc_status`, `deposit/withdrawal`, `ftd`, `bet/spin`, `reward_granted`, `postback_sent/received`, `jackpot_contribution/trigger`, `stream_sli`, `rg_guardrail_hit`.

• Metrics (RED/USE/Golden Signals), Traces (W3C traceparent), Logs (structural), Events (business), RUM/Synthetic (client/channels), Audit/WORM (unchangeable).

All schemes are versioned in Schema Registry; times are UTC/ISO-8601.

3) Transport and correlation

OpenTelemetry: a single format for metrics/logs/spans; exporters to TSDB/handlers.
W3C Trace Context: 'traceparent '/' tracestate' are thrown through redirects, APIs, webhooks, bus.
Idempotency: 'Idempotency-Key' on critical paths (payments/postbacks).
Exactly-once in meaning: hash grandfather/cursor history, webhook replay register.
Exemplars: associate latency histograms with specific 'traceId' for fast RCAs.

4) SLI/SLO model and error budgets

Golden Signals: latency, traffic, errors, saturation.
RED: Rate, Errors, Duration.
USE (infrastructure): Utilization, Saturation, Errors.

• Webhooks: delivery ≥ 99. 9%, p95 ≤ 1-2 s.
• Partner API: p95 ≤ 150-300 ms, error rate ≤ 0. 3–0. 5%.
• Event bus: lag p95 ≤ 200-500 ms; delivery ≥ 99. 9%.
• Payments/AWS: CR in the profile corridor; e2e authorization ≤ X s.
• KYC: pass-rate and SLA stages by jurisdictional profile.
• Live/SFU/CDN: e2e 2-3 s, packet loss ≤ 1%, uptime ≥ 99. 9%.
• Dashboards: freshness ≤ 1-5 s; p95 render ≤ 1. 5–2. 0 s.

Error budget: fix periods (for example, 30 days), error types (5xx, timeouts, SLO violations), auto bonus/malus rules and stop buttons.

5) Dashboards: layers and artifacts

1. Service Graph (tsepi↔uzly): topology, rps/eps, p95/p99, error-rate, saturation, heatmap streams by jurisdiction.
2. Business Flow: klik→registratsiya→KYC→depozit→FTD→stavka/raund→vyplata; conversion funnels and attribution windows.
3. Payments/KYC: CR × geo × device, failure codes, latency stages, auto cut-over with annotations.
4. Content/RGS/Live: round-trip, error-rate, SFU/CDN SLI, leaderboards and jackpots.
5. Postbacks/Attribution: timeliness, controversy, dedup, cursor lags.
6. Trust & Risk: node scorecards (SLO/ATTR/RG/SEC), "time per trace packet," Tier forecast.

Each panel contains formula versions and links to a changelog.

6) Alerting and escalation

Multi-level SLO alerts: warning (burn-rate 2 ×), criticism (burn-rate 10 ×), subsequent actions (cooling routes/limits).
Compositional triggers: "latency↑ + CR↓ + postback lag↑" → suspicion of PSP degradation.
Role channels: SRE/Payments/KYC/RGS/Marketing/Finance/Legal/RG; context immediately enables' traceId '/' runbook '/stop button.
Snooze/Muting policies for noisy metrics, but no P1 jamming.

7) RCA и war-room

SLA per trace packet: 60-90 s (P1/P2).
RCA pattern "no blame": fact → hypothesis → experiment → putting → follow-up → into action.
Release diff (§ 2 events): automatic check of collisions/formulas/configs in the incident window.
Post-mortem SLO: time to detection, to pause, to rollback, to stabilization, to publication of notes.

8) Data quality and lineage

Data Quality SLI: completeness, freshness, uniqueness ('eventId'), consistency of currencies/locales.
Lineage: from storefronts/panels to sources (schematics/versions/owners).
Oracles: signed aggregates (GGR/NetRev/SLO/RG), 'formulaVersion', 'hash (inputs)', 'kid', period.
WORM audit: immutable formula/key/exception/invoice logs.

9) Privacy, jurisdictions and security

Zero Trust: mTLS, short-lived tokens, egress-allow-list, key rotation/JWKS.
PII minimization: tokenization of 'playerId', detokenization only in safe zones; PD prohibition in logs/metrics.

ABAC/ReBAC/SoD: "see theirs and agree" access; "measure ≠ influence ≠ change."

Data localization and DPIA/DPA for markets; purge policies and TTL.

10) Cost of telemetry and cardinality management

Cardinality Budget: label limits (userId/URL/UA - prohibited; routeId/campaignId - allowed).
Histograms instead of percentiles on the fly; exemplars for selective detailing.
Adaptive sampling of traces: base percentage + priority for errors/slow paths/new versions.
Downsampling/roll-ups by age (1s→1m→5m); storage of RAW trails is short, aggregates are longer.
SLO-first: collect only what supports solutions (SLO/finance/compliance).

11) Integration with management (SRE ↔ business)

Guardrails releases and campaigns are tied to SLO/bug budgets.
Auto cut-over APM/KYC routes when metrics go beyond corridors.
RevShare/Limits: The 'Q' quality multiplier (from SLO/ATTR/RG/SEC) affects rates and quotas.
Scorecards of nodes → traffic prioritization and access to pilots.

12) Anti-patterns

"Many truths" by formula metrics and different windows.
Offset pagination of history under load (use cursors).
PII in logs/panels; PD export to BI.
Postback Zoo and unsigned webhooks → takes/holes/disputes.
Graph without 'traceId': the panel is beautiful, there is no causality.
Alert storm without burn-rate and role-playing routes.
SPOF telemetry aggregator without N + 1/DR.
Exceptions without TTL/audit are sticky overrides.

13) Checklists

Design

• Ontology of signals and circuits; versions and owners.
• W3C traceparent everywhere; Idempotency-Key on critical paths.
• SLI/SLO and error budgets; stop buttons; guardrails.
• Cardinality, sampling, retention/roll-ups policies.
• Privacy/PII: tokenization, DPA/DPIA, localization.
• Role-based alerts and runbooks.

Start

• Conformance for traces/metrics/logs; synthetic runs.
• Canary telemetry for releases; comparison panels before/after.
• War-room playbooks; SLA per trace package.

Operation

• Weekly node scorecards; burn-rate reports.
• Monthly formula changelogs and SLO/limit revisions.
• DR/xaoc exercises of aggregators/tires/storefronts.

14) Maturity Roadmap

v1 (Foundation): basic metrics + logs, single traceId, manual RCAs, primary SLOs.
v2 (Integration): OpenTelemetry everywhere, service graph, guardrails, oracle pipeline, role-playing alerts.
v3 (Automation): predictive degradation, auto cut-over APM/KYC/RGS, smart-reconciliation, limit dynamics by'Q '.
v4 (Networked Governance): inter-chain signal and oracle exchange, formula/SLO DAO rules, transparent treasuries.

15) Success metrics

Quality/risk: MTTR↓, MTTD↓, disputability <X%, auto-pause/rollback share, track coverage ≥ 95%.
Business: uplift predictability CR/FTD/ARPU/LTV, accuracy and timeliness of postbacks, stability NetRev.
Technique: p95 API/webhooks/tires/showcases in the corridors; node uptime/CDN/SFU ≥ 99. 9%.
Economy: Cost-to-Observe (CTO) per rps/event,% aggregates with exemplars, RAW storage in limits.
Compliance: 0 PD leaks, successful DPIA/DPA audits, 100% availability of WORM logs.

Brief summary

Visibility is a production trust loop: one ontology, end-to-end traces, a canon of metrics and events, SLO gardrails and data oracles, default privacy and telemetry cost discipline. Such a framework makes chains and nodes transparent, predictable and provable, and the ecosystem responsive and risk-resistant.
