There is no history import, and `fetchHistory` / `importHistory` are deliberately not implemented — Cloudflare delivers on receipt and there is no mailbox to page backwards through. `POST /channels/{id}/import-history` returns a clean \"feature not supported\".\n\n**Consequence:** if you intend to accumulate a corpus, create the routing rule as early as possible. Every week of delay is a week of mail that cannot be recovered later.\n\n### Inbound is 25 MiB; outbound is 5 MiB\n\nThese are different limits and conflating them is easy. Cloudflare rejects **inbound** messages over 25 MiB at the edge, before the Worker runs — unrecoverable, no retry. **Outbound** total message size (body plus encoded attachments) is 5 MiB; the 25 MiB figure applies to outbound only when sending to verified destination addresses.\n\nThe adapter enforces the outbound ceiling before calling the API, so an oversize send fails with a message naming the file rather than a bare 400.\n\n### It is the first email channel here with working outbound attachments\n\n`channel_imap` returns a failed result when handed attachments; `channel_gmail` does not stitch attachment URLs into its MIME body. This adapter fetches, validates and base64-encodes them, so `capabilities.fileSharing` is `true`.\n\nThat flag is a **persisted snapshot** — it is written into the channel row at connect time — so it ships `true` from 0.1.0 rather than being flipped later, which would strand already-connected channels with a stale value.\n\n---\n\n## Architecture\n\n```\nsender ─→ your-address@your-domain.com\n            │\n       Cloudflare Email Routing\n            ↓\n      Email Worker  (worker/)\n        ├─ buffers message.raw ONCE, parses with postal-mime\n        ├─ raw MIME + attachment blobs ──→ R2\n        └─ HMAC-signed envelope ──→ POST\n                 ↓\n   /api/communication_channels/webhook/cloudflare_email     (Open Mercato core)\n                 ↓\n        adapter.verifyWebhook()   ← HMAC, fail-closed\n        adapter.normalizeInbound()\n                 ↓\n        core: dedup → thread match → contact resolution → Message\n        MessageChannelLink.channelPayload = the full envelope\n                 ↓\n        event: communication_channels.message.received\n```\n\nOutbound is the mirror: `convertOutbound` fetches and encodes attachments, `sendMessage` posts to the Email Sending REST API, and a Queues event subscription feeds delivery status back through the Worker to this module's own endpoint.\n\n---\n\n## Installation\n\n```bash\nyarn mercato module add @northbound-run/channel-cloudflare-email --allow-third-party\nyarn generate\n```\n\n`--allow-third-party` is required because the package is outside the `@open-mercato/*` scope. The module ships **no entities and no migrations**, so there is nothing to migrate.\n\nRequires `communication_channels` and `integrations` to be enabled — both are declared in `requires`, so `yarn generate` fails with a clear message naming the missing module rather than dying at runtime.\n\nTo take local ownership of the source:\n\n```bash\nyarn mercato module add @northbound-run/channel-cloudflare-email --allow-third-party --eject\n```\n\n---\n\n## Cloudflare setup\n\nDeploy the Worker before connecting the channel — the connect form asks for values the Worker deployment produces.\n\n```bash\n# 1.
