Website: https://contractspec.io

Email provider implementations for ContractSpec.

## Usage

Import the root entrypoint for the domain surface, or import a concrete implementation from the `./impls/*` subpaths.

## Included Providers

- `GmailInboundProvider` for thread and message sync. `listThreadsPage` keeps
  the provider continuation; message metadata records `timestampSource`
  (`provider_internal_date`, `date_header` or `observed_at_fetch`) instead of
  presenting a fetch time as an observed provider time, and attachments are
  referenced by stable MIME part id (the Gmail attachment handle is volatile).
- `GmailMailboxReader` (`./impls/gmail-mailbox-reader`) is the read port for
  durable synchronization: mailbox profile and history baseline, keyed message
  paging, history changes (added, deleted, label changes) with a typed
  `history_expired` failure, and verified send-as identities. A message payload
  that cannot be transformed raises non-retryable `payload_invalid`.
- `createDeferredGmailOAuth2Client` (`./impls/gmail-auth`) loads the mailbox
  credential from custody on first use and on every refresh (a reconnect is
  picked up, no refresh token in configuration); a missing credential is
  `reauthorization_required`.
- `GmailAttachmentOriginalReader` (`./impls/gmail-attachments`) acquires original
  attachment bytes by message + part identity with size bounds and a SHA-256
  digest, producing a `GmailAttachmentOriginalHandOff` record
  (`./impls/gmail-evidence`) for the document-custody port. Equal bytes from two
  mailboxes share a digest but keep separate account-bound source keys.
- `GmailOutboundProvider` for Gmail-based outbound delivery. Messages are built
  by `./impls/gmail-mime` (RFC 2047 Unicode headers, Bcc, base64 parts); caller
  headers cannot set sender or envelope fields. Metadata `gmailThreadId`,
  `gmailInReplyTo` and `gmailReferences` produce a correctly threaded reply. A
  response without a message id raises `response_unverified`.
- `GmailMailboxOperations` (`./impls/gmail-mailbox`) for native drafts
  (create/update/get/send), label changes, archive (removes `INBOX` only) and
  read state. These are provider drivers; agent-initiated calls must arrive
  through Runtime Node authority.
- `parseGmailPushNotification` and `GmailWatchOperations` (`./impls/gmail-push`)
  treat Gmail push as a wake signal only; changes are fetched through history.
- `MicrosoftGraphOutboundProvider` for delegated Microsoft user mail. Graph
  `202 Accepted` is represented as queued acceptance without a provider message
  id; ambiguous responses retain only sanitized diagnostic correlations.
- `MicrosoftGraphInboundProvider` for folder-scoped message delta sync. Complete
  opaque next/delta links are mailbox-bound, and deletion tombstones remain
  explicit reconciliation inputs.
- `MicrosoftGraphMessageSubscriptionManager` for bounded create, renewal, and
  deletion of Outlook message subscriptions. Notification batches require exact
  subscription/client-state binding; missed lifecycle events require delta sync.
- `PostmarkEmailProvider` for transactional email delivery
- `ResendEmailProvider` for outbound delivery with provider-native retry
  idempotency through a bounded `EmailOutboundMessage.idempotencyKey`
- `MailerSendEmailProvider` for outbound text, HTML, template, scheduled, bulk,
  personalized, tagged, header, CC/BCC/reply-to, and inline/regular attachment
  delivery through the official MailerSend REST API
- `MailerSendInboundProvider` for official inbound-route list/get/create/update/
  delete operations with email and webhook forwards
- `ingestMailerSendWebhook` and `authenticateMailerSendWebhook` for raw-body
  HMAC-SHA256 verification, delivery receipts, inbound MIME projections, test
  callbacks, replay suppression, and non-regressing delivery status
- `ingestResendWebhook` for raw-body signature verification and `svix-id`
  replay deduplication plus non-regressing provider-message status projection
  through a caller-owned atomic event store. Results expose only a deterministic
  `provider-message:sha256:*` reference; raw provider message ids remain transient.
- `SqlResendWebhookEventStore` (`./impls/resend-webhook-sql-store`) is the
  durable SQL implementation of that store for a pg-compatible pool (no `pg`
  dependency): one transaction inserts into the host's replay ledger, rejects an
  event id reused for different content, advances the per-message status only
  for a higher `RESEND_DELIVERY_STATUS_RANKS` rank or a later equal-rank event,
  and runs an optional `onStatusApplied` host hook in the same transaction. Hosts
  own the two tables (validated plain identifiers) and their migrations; every
  failure surfaces as retryable `ResendWebhookStoreUnavailableError`.

## MailerSend

Use the focused exports so browser bundles never pull server-only provider code:

```ts
import { MailerSendEmailProvider } from
  "@lssm-tech/integration.provider-email/impls/mailersend-email";
import { MailerSendInboundProvider } from
  "@lssm-tech/integration.provider-email/impls/mailersend-inbound";
import { ingestMailerSendWebhook } from
  "@lssm-tech/integration.provider-email/impls/mailersend-webhook";
```


The caller supplies `apiKey` and may inject `baseUrl` and `fetch`. Credentials
must remain in a server-side vault; provider errors expose only status and a
normalized code. Webhooks must pass the exact raw request body and `Signature`
header with the endpoint signing secret. A successful handler should respond
within three seconds; durable stores must deduplicate event ids because
MailerSend retries failed delivery.

Inbound webhook projections preserve text, HTML, raw MIME, recipients, headers,
SPF/DKIM results, and inline/regular attachments. Application code remains
responsible for retention, attachment storage, malware scanning, and workspace
policy before content enters CommunicationOS projections or AI context.

## Compatibility

This package owns the email implementation slice split out of `@lssm-tech/integration.providers-impls`. The legacy package continues to re-export these subpaths for existing consumers.
