Contract and lifecycle

Grain: One contextual attempt fact per (execution_id, attempt_kind, step_index or observation_index, frame_index); attempt_id identifies the reusable physical attempt.
Lifecycle: run publishes this immutable row set atomically with its owning run. Statement failure or caller rollback publishes no durable prefix; direct DML is unsupported because it can corrupt the documented invariants.
Status and NULLs: Interpret nullable payloads only through their owning status fields. Defensive poisoned and engine_error outcomes mean the engine refused to claim a trustworthy normal result; broad view nullability also covers owner alternatives and left-joined evidence.
Join guidance: Join evm.executions on execution_id for candidate and run context.
Use attempt_id to deduplicate physical facts expanded across contextual owners.
For program owners use step_index; for observation-call owners use observation_index and observation_key.
Effect semantics: Access flags describe attempted EVM access, not committed state change.
Effect facts retain attempted evidence and final committed, reverted, discarded, or poisoned disposition.
execution_state_deltas contains committed checkpoint transitions only; observation-call effects are excluded from execution_effect_summary.

Columns

Identity and ownership

Name	Type
`execution_id`	UUID Contextual execution association identity; do not use it as reusable artifact identity.
`attempt_kind`	VARCHAR Owner kind: program_step or observation_call.
`observation_key`	VARCHAR Byte-exact caller observation identity for an observation_call owner; otherwise NULL.
`attempt_id`	UUID Reusable physical attempt identity; contextual owners may share this value.

Contextual keys and reusable identities that establish row ownership.

Chain context

Name	Type
`chain_id`	UBIGINT EVM chain identifier frozen for the owning execution.
`chain_profile`	VARCHAR Named chain-rules profile frozen for the owning execution.

Pinned chain, block, profile, and revision context.

Ordering and cardinality

Name	Type
`step_index`	UINTEGER Zero-based program order; NULL for observation_call attempt owners.
`observation_index`	UINTEGER Zero-based expanded point order; identifies observation-call ownership.
`frame_index`	UINTEGER Frame that produced the BLOCKHASH read
`global_index`	UINTEGER Global append-order fact index
`frame_local_index`	UINTEGER Frame-local append-order fact index

Showing fewer

Stable indexes and counts used to reconstruct deterministic order.

Payload and evidence

Name	Type
`current_block_number`	UBIGINT Execution block number
`requested_block_number`	UBIGINT BLOCKHASH argument
`canonical`	BOOLEAN Whether the returned value is canonical evidence
`synthetic`	BOOLEAN Whether the returned value is synthetic/dev evidence
`source`	VARCHAR Resolution source

Showing fewer

Operation-specific inputs, outputs, and authenticated evidence.

Status and disposition

Name	Type
`status`	VARCHAR Resolution status

Outcome vocabulary and NULL-controlling disposition fields.

Commitments

Name	Type
`block_hash`	BYTES32 Returned block hash

Hashes and roots authenticating specifications, facts, state, or results.
