# Explorer Transaction Compliance Matrix

Purpose: define the first explorer-side heuristic for grading how well a transaction is evidenced, decoded, and aligned with the repo's GRU, x402, and ISO-20022 posture.

This matrix is intentionally operational and observational. It is not a legal opinion, regulatory ruling, or substitute for off-chain compliance controls.

## Scope

Use this score to:
- triage transactions in the explorer
- understand how much structured evidence is visible
- highlight transactions that deserve deeper human review

Do not use this score as:
- final regulatory approval
- final settlement approval
- a substitute for policy-engine, KYC, AML, or ledger review

## Score

Total: `100`

### 1. Execution Integrity

Weight: `25`

Signals:
- success vs failure
- presence of mined execution context
- overall confidence that the transaction actually completed as intended

### 2. Decode Clarity

Weight: `15`

Signals:
- method label is known
- decoded input parameters are visible
- explorer can show structured intent rather than raw calldata only

### 3. Counterparty Traceability

Weight: `15`

Signals:
- sender visible
- recipient or created contract visible
- block anchoring visible
- timestamp visible

### 4. Asset Posture

Weight: `20`

Signals:
- transferred assets appear GRU-aware
- transferred assets appear x402-ready where relevant
- transferred assets appear ISO-20022-aligned in the local explorer posture

Notes:
- this is neutral rather than punitive for transactions that do not include token transfers
- this is an explorer-side view based on local GRU intelligence, not a final institutional judgment

### 5. Audit Richness

Weight: `15`

Signals:
- token transfers indexed
- internal calls visible
- raw input visible
- decoded input visible

### 6. Exception Hygiene

Weight: `10`

Signals:
- explicit revert reason
- failed execution
- obvious exception posture that lowers confidence

## Grades

- `A`: `90-100`
- `B`: `80-89`
- `C`: `70-79`
- `D`: `60-69`
- `E`: `<60`

## Interpretation

- `A` means the explorer has strong structured evidence and the transaction is easy to review operationally.
- `B` means the transaction is still strong, but some context is missing.
- `C` means the transaction is understandable but not richly evidenced.
- `D` means review confidence is thin.
- `E` means the explorer-visible posture is weak and deserves caution.

## Current Limitations

- The matrix does not ingest off-chain policy decisions.
- The matrix does not prove legal or regulatory sufficiency.
- The matrix does not parse full ISO-20022 payloads.
- The matrix depends on explorer indexing quality and local GRU intelligence coverage.

## Next Upgrades

- add log-level standards and event scoring
- add ISO correlation identifiers when available
- add bridge-lane and cross-chain settlement evidence
- add reserve and governance posture where directly linked to tx context
