email.atmos · 13- email.atmos.attestation record A PDS operator's declaration of cooperative membership and mail domain control. The labeling service verifies DNS configuration (MX, SPF, DKIM, DMARC) independently and applies verification labels to the operator's DID. The record key is the attested domain.
- email.atmos.calendar space Experimental Comail calendar Space. Calendar policies, event revisions and request claims are append-only. These collections describe the OAuth consent boundary; clients must validate the exact Space, grant and history before accepting data.
- email.atmos.calendarPersonal space Private calendar preferences and source settings. Each account controls its own Space and separate consent.
- email.atmos.contacts space Private personal contacts and append-only operation history. Each account controls its own Space and separate consent.
- email.atmos.defs defs Shared definitions for the Comail cooperative. Documents the label vocabulary used by the cooperative labeler; the labeler emits the corresponding kebab-case string values.
- email.atmos.filePersonal space Private file metadata, content chunks, manifests and deletion history. Each account controls its own Space and separate consent.
- email.atmos.folderOperation record ALPHA. Immutable operation claim created atomically with one folder revision. Its deterministic key is scoped to the author repository, stable folder ID, and operation ID, so a retry with changed payload collides safely.
- email.atmos.folderRevision record ALPHA. Immutable create-only causal revision for one 71-character stable folder identity. The revision and deterministic email.atmos.folderOperation claim are created atomically. Standard role identities, names, and roles are canonical and cannot be renamed, rebound, or deleted. Custom rename conflicts reduce by revision height then unsigned UTF-8 operation-ID order; tombstone is grow-only.
- email.atmos.mailbox space ALPHA. Private Comail mailbox space for the official AT Protocol Spaces alpha. Canonical message content is immutable; mailbox and folder state use create-only causal revisions with deterministic reduction. These collections are the least-privilege OAuth recommendation, not a protocol write allowlist; certified adapters must reject unexpected authority collections. Legacy fixed-rkey mutable snapshots are deliberately excluded.
- email.atmos.message record ALPHA. An immutable private Comail message. Canonical RFC 5322 bytes are stored in the referenced permissioned blob; integrity and delivery metadata allow a standards-facing mailbox to be rebuilt.
- email.atmos.messageStateOperation record ALPHA. Immutable operation claim created atomically with one message-state revision. Its deterministic key is scoped to the author repository, logical message, and operation ID, so a retry with changed payload collides instead of poisoning the revision graph.
- email.atmos.messageStateRevision record ALPHA. Immutable create-only causal revision for one logical Comail message. Writers reference every observed head and atomically create a deterministic email.atmos.messageStateOperation claim. Reducers validate a commit-bound complete graph, resolve independent fields by revision height then unsigned UTF-8 operation-ID order, and treat tombstone as irreversible.
- email.atmos.messagesPrototype space Private and shared email inboxes for the Comail Messages prototype. Stores messages, attachments, drafts, sent replies and mail state. Shared inbox membership is managed by the inbox owner.
- email.atmos.calendar.policy record ALPHA. Append-only Calendar membership policy. Host validates identity, permissions and causal history before accepting records.
- email.atmos.calendar.proposal record ALPHA. Append-only proposed Calendar event edit. Host validates identity, permissions and causal history before accepting records.
- email.atmos.calendar.revision record ALPHA. Append-only accepted Calendar event revision. Host validates identity, permissions and causal history before accepting records.
- email.atmos.calendarPersonal.properties record ALPHA. Actor-private Calendar property revisions and exact retry claims. Host validates identity, permissions and causal history before accepting records.
- email.atmos.calendarPersonal.sources record ALPHA. Actor-private Calendar source preference revisions and exact retry claims. Host validates identity, permissions and causal history before accepting records.
- email.atmos.filePersonal.chunk record One immutable base64 private-file byte chunk in an actor-owned file Space.
- email.atmos.filePersonal.file record Immutable metadata for one actor-private file revision.
- email.atmos.filePersonal.manifest record Immutable manifest for actor-private file record chunks.
- email.atmos.filePersonal.tombstone record Immutable actor-private file tombstone with the exact removed heads.
