Financial Systems Integrity Platform
Make execution behavior machine‑checkable.
Tusiro is a financial systems integrity platform. One shared correctness and evidence core. Three surfaces over a single semantic nucleus — verification, adversarial testing, runtime protection.
What Tusiro Answers
Three QuestionsBefore production
Can the target system survive semantically hostile but protocol-valid conditions?
During operation
Did the target system actually behave according to its declared execution rules?
During incidents
Once trust has degraded, how can the system be contained audibly without inventing false certainty?
Platform Architecture
One shared core. Three surfaces. No fragmentation.
The same correctness contract is reusable across offline verification, adversarial scenario targeting, and bounded runtime protection. One semantic nucleus. No schema forks per surface. No customer shortcut may poison the shared core.
Positioning
What Tusiro is. What Tusiro is not.
What Tusiro Is
A financial systems integrity platform
Formal correctness and evidence system for market-connected execution stacks.
A specification-driven verification system
Machine-checkable contracts over canonical events, not heuristics or operator memory.
A typed evidence system
Observed fact, derived state, admissibility, contradiction, phase, and downstream actionability, each as a distinct typed record.
A shared-core platform
One semantic nucleus reused across verification, adversarial testing, and runtime protection.
What Tusiro Is Not
Not a trading strategy engine
No alpha generation, no portfolio optimization, no trading decisions.
Not a matching engine or custody platform
Not a venue. Not order routing.
Not a generic observability dashboard
Not a logging tool repackaged as insight.
Not an LLM-driven execution controller
No language model in the critical runtime or decision path.
Not a consultancy junk drawer
No per-customer rule hacks that fragment the shared semantic core.
Platform Surfaces
One shared correctness core. Three surfaces.
Each surface reuses the same semantic nucleus — canonical events, contracts, evaluator, dispatcher, evidence ledger. Sequenced honestly: verification first, adversarial testing and runtime protection architected ahead.
Execution Correctness Verification
Offline audit of whether a historical execution stream is semantically consistent with its declared lifecycle rules. Produces typed contradictions, phase transitions, verdicts, derived claims, and a full causal chain in the evidence ledger.
Canonical Events · Contract Evaluation · Evidence Ledger
Adversarial Resilience Testing
Target systems exercised against protocol-valid but semantically hostile conditions, derived from the same contracts used in verification. Shared truth layer. No duplicated rule systems across surfaces.
Scenario Derivation · Contract Reuse · Bounded Stress
Runtime Protection
Bounded, audible runtime containment once trust has degraded. No blind market flatten. No LLM in the critical decision path. Operator intent and recovery boundaries preserved.
