Title:
🔎 Structural Observability: Traces, Coverage, and Postmortems
🔗 https://huggingface.co/blog/kanaria007/structural-observability
---
Summary:
When conventional systems fail, you dig through logs, metrics, and RPC traces.
In a Structured Intelligence stack, that’s not enough—you need structural answers:
*What did the system see ([OBS]) before acting? Which goal surfaces were active ([EVAL])? Which Jump/engine produced the decision? Which RML effects executed (and which compensators ran)? Which PoLB mode / release / experiment context was in force?*
This article introduces *Structural Observability*: full-stack structured traces anchored on the *SIR* (episode record), plus cross-cutting *JumpTrace / RMLTrace / EvalTrace / EthicsTrace / GeniusTrace* so incidents can be replayed and explained—without hand-wavy storytelling.
> Logs are strings.
> Structural observability is *reconstructable decision anatomy*.

Why It Matters:
• Makes postmortems answerable: “what happened?” becomes *traceable structure*, not vibes
• Turns key SI metrics into real operational signals: *SCover / SCI / CAS*
• Prevents silent contradictions (e.g., “ETH blocked” but an effect still fired) via consistency checks
• Enables deterministic re-runs and audit-grade bundles (portable, hashable, exportable)

What’s Inside:
• A full-stack trace model: World → OBS/SIM/SIS → *SIR* → JumpRuntime → RML Engine → Effects
• How to design trace envelopes and coverage so *SCover* is meaningful
• What “Structural Consistency Incidents (SCI)” look like in practice, and how to postmortem them
• *CAS* and deterministic re-run routines (what must be pinned to get stable outputs)
• Portability conventions for exported/hashed traces (canonicalization, no-float policies, scaled ints)
