Expand description

Why an access or allowlist rule was rejected. Reasons stay machine-readable; they must never exist only in a human detail string.

Variants§

UnknownResource

The resource ID is not offered by this proxy instance.

UnsupportedWidth

The requested width is not supported.

UnsupportedAccessClass

The requested access class is not supported by the V1 executor.

Misaligned

The offset is not aligned to the access width.

OffsetOverflow

offset + width overflows.

OutOfLogicalBounds

The access does not fit the logical resource size.

OutOfMappedBounds

The access does not fit the actual backing mapping.

NotPermittedByCeiling

The target ceiling has no entry for this resource.

HardDenied

The offset lies in a hard-denied range; operator consent cannot enable it.

UnknownReadsNotPermitted

The ceiling does not permit operator-authorized unknown reads on this resource.

PollNotPermitted

The ceiling does not permit polling on this resource.

NotInAllowlist

No exact session allowlist rule matches the access.

LimitExceeded

A bounded-execution limit (for example maximum snapshot items) was exceeded.

StaleIdentity

A session-open expectation (boot, generation, or digest) was stale. Used in audit records for rejected session opens.

MutationLeaseContention

The exclusive mutation lease was already held.

NotAccepting

The proxy is stopping and accepts no new sessions.

UnsupportedExpectation

The request set a field this phase does not implement (for example a phase 2 takeover expectation). Fail closed rather than silently ignoring the field.

PreconditionFailed

A precondition specified for a write failed.

MissingPrecondition

Target policy requires a precondition, but none was provided.

Timeout

An asynchronous poll timed out without matching.

ReadOnlySession

A write was attempted in a read-only session.

WriteNotPermitted

A write was attempted to an offset or bits not permitted by target policy.

UnsupportedMethod

A requested protocol method is not permitted by target policy.

TransferTooLarge

A requested protocol transfer exceeds maximum allowed size.
