When set, the namespace is container-enabled. Valid only on live entries. - `state?: "created"` Live export. May be omitted; defaults to `created`. - `"created"` - `WorkersDurableObjectDeletedExport` A `deleted` tombstone: retires the provisioned namespace for this class and all of its data.

Deletion is irreversible. - `state: "deleted"` Tombstone that deletes the namespace. - `"deleted"` - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `WorkersDurableObjectRenamedExport` A `renamed` tombstone: rewrites the provisioned namespace's class name from this map key to `renamed_to`. The source class may stay in code during the rollout window (an info notice is emitted). `storage`, `transferred_to` and `transfer_from` are not allowed. - `renamed_to: string` The destination class name. Must differ from the source class (the map key) and must be declared as a live (`created`) entry in the same `exports` map. Write-only: never present in GET responses. - `state: "renamed"` Tombstone that renames the namespace's class. - `"renamed"` - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `WorkersDurableObjectTransferredExport` A `transferred` tombstone (source side of a two-phase transfer): hands ownership of the provisioned namespace to another script in the same account, named by `transferred_to`. The target must have already deployed a matching `expecting-transfer` entry. The source class may stay in code during the rollout window (an info notice is emitted). `storage`, `renamed_to` and `transfer_from` are not allowed. - `state: "transferred"` Tombstone that transfers the namespace to another script. - `"transferred"` - `transferred_to: string` The destination script name. Must be in the same account and the same dispatch-namespace context (or both non-dispatch). Cross-dispatch-namespace transfers are rejected. Write-only: never present in GET responses. - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `WorkersDurableObjectExpectingTransferExport` The target side of a two-phase transfer (`state: expecting-transfer`). Declares that this script expects to receive a namespace for this class from the `transfer_from` script. This is a live entry, not a tombstone: bindings resolve through the source's namespace until the source commits with a `transferred` tombstone. `storage` and `transfer_from` are required; `renamed_to` and `transferred_to` are not allowed. - `state: "expecting-transfer"` Target side of a two-phase transfer. - `"expecting-transfer"` - `storage: "sqlite" | "legacy-kv"` Durable Object storage backend. `sqlite` is the recommended (and only) backend for new namespaces. `legacy-kv` is accepted only for a class whose namespace already exists as KV-backed; the `exports` flow never provisions a new `legacy-kv` namespace. - `"sqlite"` - `"legacy-kv"` - `transfer_from: string` The source script name to receive the namespace from. Must be in the same account and dispatch-namespace context. Present on reads for `expecting-transfer` entries. - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `container?: string` Name of the container (declared in the upload's `metadata.containers`) that backs this Durable Object once the transfer settles. Valid only on live entries. - `exports_reconciliation?: ExportsReconciliation` Summary of the declarative exports reconciliation that ran on this upload. Populated only when the uploaded metadata included an `exports` block. Durable Object entries drive reconciliation; `type: worker` entries do not contribute to this summary. - `created: Array` Class names for which a new namespace was provisioned. - `deleted: Array` Class names whose namespace was deleted by a `deleted` tombstone. - `info: Array` Non-blocking info entries (stale tombstones, tombstone applied with class still in code). See `exports_reconciliation_info`. - `class: string` The class name the info entry is about. - `message: string` Human-readable explanation. - `scenario: "code_class_not_in_exports" | "provisioned_class_missing_from_config" | "config_export_not_in_code" | 30 more` Stable, machine-readable tag identifying which reconciliation scenario produced an error, warning, or info entry.

The source class may stay in code during the rollout window (an info notice is emitted). `storage`, `transferred_to` and `transfer_from` are not allowed. - `renamed_to: string` The destination class name. Must differ from the source class (the map key) and must be declared as a live (`created`) entry in the same `exports` map.

The target must have already deployed a matching `expecting-transfer` entry. The source class may stay in code during the rollout window (an info notice is emitted). `storage`, `renamed_to` and `transfer_from` are not allowed. - `state: "transferred"` Tombstone that transfers the namespace to another script. - `"transferred"` - `transferred_to: string` The destination script name. Must be in the same account and the same dispatch-namespace context (or both non-dispatch). Cross-dispatch-namespace transfers are rejected. Write-only: never present in GET responses. - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `WorkersDurableObjectExpectingTransferExport` The target side of a two-phase transfer (`state: expecting-transfer`). Declares that this script expects to receive a namespace for this class from the `transfer_from` script. This is a live entry, not a tombstone: bindings resolve through the source's namespace until the source commits with a `transferred` tombstone. `storage` and `transfer_from` are required; `renamed_to` and `transferred_to` are not allowed. - `state: "expecting-transfer"` Target side of a two-phase transfer. - `"expecting-transfer"` - `storage: "sqlite" | "legacy-kv"` Durable Object storage backend. `sqlite` is the recommended (and only) backend for new namespaces. `legacy-kv` is accepted only for a class whose namespace already exists as KV-backed; the `exports` flow never provisions a new `legacy-kv` namespace. - `"sqlite"` - `"legacy-kv"` - `transfer_from: string` The source script name to receive the namespace from. Must be in the same account and dispatch-namespace context. Present on reads for `expecting-transfer` entries. - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `container?: string` Name of the container (declared in the upload's `metadata.containers`) that backs this Durable Object once the transfer settles. Valid only on live entries. - `exports_reconciliation?: ExportsReconciliation` Summary of the declarative exports reconciliation that ran on this upload. Populated only when the uploaded metadata included an `exports` block. Durable Object entries drive reconciliation; `type: worker` entries do not contribute to this summary. - `created: Array` Class names for which a new namespace was provisioned. - `deleted: Array` Class names whose namespace was deleted by a `deleted` tombstone. - `info: Array` Non-blocking info entries (stale tombstones, tombstone applied with class still in code).

Declares that this script expects to receive a namespace for this class from the `transfer_from` script. This is a live entry, not a tombstone: bindings resolve through the source's namespace until the source commits with a `transferred` tombstone. `storage` and `transfer_from` are required; `renamed_to` and `transferred_to` are not allowed. - `state: "expecting-transfer"` Target side of a two-phase transfer. - `"expecting-transfer"` - `storage: "sqlite" | "legacy-kv"` Durable Object storage backend. `sqlite` is the recommended (and only) backend for new namespaces. `legacy-kv` is accepted only for a class whose namespace already exists as KV-backed; the `exports` flow never provisions a new `legacy-kv` namespace. - `"sqlite"` - `"legacy-kv"` - `transfer_from: string` The source script name to receive the namespace from. Must be in the same account and dispatch-namespace context. Present on reads for `expecting-transfer` entries. - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `container?: string` Name of the container (declared in the upload's `metadata.containers`) that backs this Durable Object once the transfer settles. Valid only on live entries. - `exports_reconciliation?: ExportsReconciliation` Summary of the declarative exports reconciliation that ran on this upload. Populated only when the uploaded metadata included an `exports` block. Durable Object entries drive reconciliation; `type: worker` entries do not contribute to this summary. - `created: Array` Class names for which a new namespace was provisioned. - `deleted: Array` Class names whose namespace was deleted by a `deleted` tombstone. - `info: Array` Non-blocking info entries (stale tombstones, tombstone applied with class still in code).

The target must have already deployed a matching `expecting-transfer` entry. The source class may stay in code during the rollout window (an info notice is emitted). `storage`, `renamed_to` and `transfer_from` are not allowed. - `state: "transferred"` Tombstone that transfers the namespace to another script. - `"transferred"` - `transferred_to: string` The destination script name. Must be in the same account and the same dispatch-namespace context (or both non-dispatch). Cross-dispatch-namespace transfers are rejected.

Declares that this script expects to receive a namespace for this class from the `transfer_from` script. This is a live entry, not a tombstone: bindings resolve through the source's namespace until the source commits with a `transferred` tombstone. `storage` and `transfer_from` are required; `renamed_to` and `transferred_to` are not allowed. - `state: "expecting-transfer"` Target side of a two-phase transfer. - `"expecting-transfer"` - `storage: "sqlite" | "legacy-kv"` Durable Object storage backend. `sqlite` is the recommended (and only) backend for new namespaces. `legacy-kv` is accepted only for a class whose namespace already exists as KV-backed; the `exports` flow never provisions a new `legacy-kv` namespace. - `"sqlite"` - `"legacy-kv"` - `transfer_from: string` The source script name to receive the namespace from. Must be in the same account and dispatch-namespace context. Present on reads for `expecting-transfer` entries. - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `container?: string` Name of the container (declared in the upload's `metadata.containers`) that backs this Durable Object once the transfer settles. Valid only on live entries. - `exports_reconciliation?: ExportsReconciliation` Summary of the declarative exports reconciliation that ran on this upload. Populated only when the uploaded metadata included an `exports` block.

The target must have already deployed a matching `expecting-transfer` entry. The source class may stay in code during the rollout window (an info notice is emitted). `storage`, `renamed_to` and `transfer_from` are not allowed. - `state: "transferred"` Tombstone that transfers the namespace to another script. - `"transferred"` - `transferred_to: string` The destination script name. Must be in the same account and the same dispatch-namespace context (or both non-dispatch). Cross-dispatch-namespace transfers are rejected.

Declares that this script expects to receive a namespace for this class from the `transfer_from` script. This is a live entry, not a tombstone: bindings resolve through the source's namespace until the source commits with a `transferred` tombstone. `storage` and `transfer_from` are required; `renamed_to` and `transferred_to` are not allowed. - `state: "expecting-transfer"` Target side of a two-phase transfer. - `"expecting-transfer"` - `storage: "sqlite" | "legacy-kv"` Durable Object storage backend. `sqlite` is the recommended (and only) backend for new namespaces. `legacy-kv` is accepted only for a class whose namespace already exists as KV-backed; the `exports` flow never provisions a new `legacy-kv` namespace. - `"sqlite"` - `"legacy-kv"` - `transfer_from: string` The source script name to receive the namespace from. Must be in the same account and dispatch-namespace context. Present on reads for `expecting-transfer` entries. - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `container?: string` Name of the container (declared in the upload's `metadata.containers`) that backs this Durable Object once the transfer settles. Valid only on live entries. - `exports_reconciliation?: ExportsReconciliation` Summary of the declarative exports reconciliation that ran on this upload. Populated only when the uploaded metadata included an `exports` block. Durable Object entries drive reconciliation; `type: worker` entries do not contribute to this summary. - `created: Array` Class names for which a new namespace was provisioned. - `deleted: Array` Class names whose namespace was deleted by a `deleted` tombstone. - `info: Array` Non-blocking info entries (stale tombstones, tombstone applied with class still in code). See `exports_reconciliation_info`. - `class: string` The class name the info entry is about. - `message: string` Human-readable explanation. - `scenario: "code_class_not_in_exports" | "provisioned_class_missing_from_config" | "config_export_not_in_code" | 30 more` Stable, machine-readable tag identifying which reconciliation scenario produced an error, warning, or info entry.
