Why a MetaCommand was refused at apply. Refusals are deterministic (every replica reaches the same conclusion from the same state) and never fault the raft state machine: they are journaled in MetaState::rejections and reported to the proposer by MetaGroup::propose.

Variants

FeatureActivation(FeatureActivationError)

Feature activation failed validation (spec section 11.8 step 5; re-validated at apply, ADR-0010 decision 4).

SecretSettingKey

The setting key is on the secrets denylist (spec section 16.2).

Fields

key: String

The denied key.

UnknownSettingKey

The setting key maps to no typed setting.

Fields

key: String

The unknown key.

InvalidSettingValue

The setting value failed typed parsing or validation.

Fields

key: String

The setting key.

reason: String

Why the value failed.

StaleWrite

A last-writer-wins guard rejected an out-of-date write.

Fields

resource: String

What was being written.

current: MetadataVersion

Version currently stored.

attempted: MetadataVersion

Version the command carried.

Conflict

The command conflicts with existing state.

Fields

resource: String

What conflicted.

reason: String

Why it conflicted.

NotFound

A referenced record does not exist.

Fields

resource: String

What was looked up.

Invalid

The command itself is malformed.

Fields

reason: String

Why the command is invalid.

ProposalFailed

A meta-plane binding’s proposal transport failed (leader loss, timeout, shutdown) before the command’s outcome was known. Never journaled from apply — apply-time refusals are deterministic; this surfaces only through the crate::split::TabletMetaPlane/crate::merge::MergeMetaPlane seams the node runtime drives. Every split/merge descriptor write is idempotent, so retrying the failed step is safe.

Fields

reason: String

What failed.

NotLeader

The node receiving the proposal is not the meta leader (spec section 11.7): the caller re-resolves the leader and retries there. Carried structured (never stringified) so gateways and split/merge drivers can pattern-match it; split/merge descriptor writes are idempotent, so the retry is safe.

Fields

leader: Option<u64>

The node’s current belief about the meta leader’s raft id, if any.
