Domain-anchored deterministic canonicalization clearing kernel with versioned routing, two-phase rail evidence, governance-to-ledger binding, and recomputable proof sets

A computer-implemented method comprising:

• (a) receiving a namespace address;
• (b) resolving, by a namespace parser, the namespace address into a hierarchical account graph;
• (c) computing, by an inheritance rule engine, an effective parameter set for a selected account node using deterministic inheritance and override precedence rules;
• (d) generating snapshot_id binding policy_version_id and an effective time window to the effective parameter set;
• (e) canonicalizing, under canonical_profile_id, an intent into a byte-identical canonical intent envelope, computing tx_hash under hash_function_id, and verifying a digital signature over tx_hash;
• (f) generating a unified payment routing key using at least snapshot_id;
• (g) evaluating, by a deterministic risk finite-state machine, one or more risk constraints and gating execution prior to an atomic commit boundary while emitting reason codes;
• (h) executing an atomic debit-credit transformation at the atomic commit boundary with idempotency protection and enforcing a nonce gate;
• and
• (i) applying a settlement matrix bound to the hierarchical account graph to distribute value and record reconciliation outputs, and returning a proof set enabling third-party recomputation.

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to:

• (a) resolve a namespace address into a hierarchical account graph;
• (b) compute an effective parameter set using deterministic inheritance and override precedence rules;
• (c) generate snapshot_id binding policy_version_id and an effective time window;
• (d) construct a byte-identical canonical intent envelope under canonical_profile_id and compute tx_hash under hash_function_id;
• (e) generate a unified payment routing key using at least snapshot_id;
• (f) gate a transaction using a deterministic risk finite-state machine prior to an atomic commit boundary;
• (g) perform an atomic debit-credit transformation with idempotency protection and nonce gating;
• (h) persist an append-only tamper-evident audit log and apply a settlement matrix bound to the hierarchical account graph;
• and
• (i) provide a verification interface returning a proof set for third-party recomputation.
