How to read the evidence markers

Evidence levels (how strong an address label is)

evidence level: primary source The vendor or protocol itself publishes this exact address
evidence level: self-description What the contract says about itself via a getter; contracts can claim any name
evidence level: cluster Shares a key, getter or bytecode with labelled addresses: same machinery, not proof of the same operator
evidence level: hint Ranking, explorer tag, metadata or third-party label: a clue, never proof
evidence level: unlabelled No registry label. In running text, an address without a marker has no label.

Evidence grades (how a value was obtained), strongest first

grade: observed grade: decoded grade: recomputed grade: recovered grade: contract read grade: inferred grade: unknown

Weaker grades are set in italics. Hover or focus a marker for its definition; full definitions.

Outer transaction reverted (status 0): the receipt has no logs; every effect was undone.

What happened

The outer transaction reported reverted grade: observed; this UserOperation unknown grade: unknown.

Call 1 not executed grade: observedthe whole outer transaction reverted, so nothing it requested took effect

Money for this operation

No per-operation charge: the outer transaction reverted, so the EntryPoint charged nothing and the bundler alone paid the receipt fee.

Sponsorship: sponsored, terms not visible: a paymaster pays the gas charge from its deposit; its terms (free, token-paid, off-chain billing) are not decodable from this record grade: decoded

The call trace

an error deep in the call tree can be caught by a caller; only the outer status and the UserOp success flag say what persisted

1 operation charge

The outer fee (what the bundler paid the network) and the per-op charges (what the EntryPoint collected from deposits and paid to the beneficiary) are different quantities. They are listed, never added together; their difference is not 'bundler profit'.

What we can't tell

The signer is a key (address) recovered from the signature. It does not tell you which person, company or bot controls that key.
A paymaster paid the gas charge, but that does not mean the user paid nothing: the paymaster may bill the user off-chain or in a token (see sponsorship mode).
The beneficiary is only where gas compensation was sent; it is not the user, and it is not proof of who runs the bundler.
Some labels are only at 'hint' or 'cluster' level; treat them as leads, not identity.
Names (token symbols, labels) are metadata unless their evidence level says otherwise.
The outer fee is what the bundler paid the network for the whole transaction; it cannot be split fairly across ops or legs, and comparing it with the per-op charges does not give bundler profit.
Because the outer transaction reverted there are no logs: we only know what was requested, not why it failed (a trace or replay would be needed).
