The RSS feed already advertised hub and self via the Link response
header, but the Atom feed was missing it entirely. Subscribers using
Atom had no way to discover the hub for real-time push notifications.

Moves validation of POST /api/feeds/:feedId/update from inline
schema.parse() to zValidator middleware. The route now receives
typed validated data via c.req.valid("json"), and returns a
structured {success: false, error: ZodIssue[]} on invalid input.

Fixes a bug where routes returning raw `new Response()` (RSS, Atom,
entries) were not receiving CORS headers — hono/cors applies headers
after next(), covering all response paths.

- Add KV feed existence check in hub.ts to prevent SSRF via non-existent feeds (returns 404)
- Treat empty string hub.secret as absent (|| instead of ??)
- Remove misleading hub Link header from atom.ts (hub only supports RSS topics)
- Simplify double-layered hub router in index.ts (direct app.route instead of nested Hono)
- Update hub.test.ts to seed KV with feed config for tests requiring valid subscribe/unsubscribe

Pass ExecutionContext through the email processing chain so notifySubscribers
is called via ctx.waitUntil after a new email is stored.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Add comprehensive tests for POST /hub validation (missing fields, unknown mode, non-HTTPS callback, invalid URL, wrong domain, secret > 200 bytes) and happy-path subscribe/unsubscribe (202). Also fix hub.ts to use a waitUntilSafe wrapper so executionCtx.waitUntil doesn't throw in Node test environments.

- Add ESLint 9 flat config (eslint.config.mjs) with typescript-eslint
recommended rules and eslint-config-prettier
- Add lint-staged to run eslint+prettier only on staged files
- Update pre-commit hook to use lint-staged instead of full prettier check
- Add `lint` and `format:check` scripts to package.json
- Add Lint step to CI workflow
- Fix resulting lint errors: unused vars (_ctx, _options, catch binding),
any→unknown in type declarations, stale eslint-disable comments

Attachments from incoming emails are uploaded to an optional Cloudflare R2
bucket and exposed as <enclosure> elements in RSS and <link rel="enclosure">
in Atom feeds, served at /files/{id}/{filename} with immutable caching.
R2 is opt-in: if ATTACHMENT_BUCKET is not bound the feature is a no-op.
Attachments are cleaned up from R2 on email/feed deletion and during
size-based feed trimming. Adds MockR2 to the test setup.

Emails are now trimmed from the oldest end when total serialised size
exceeds FEED_MAX_SIZE_BYTES (default 512 KB). Each EmailMetadata entry
stores its size so future trims are computed without re-reading KV.
Adds FEED_MAX_SIZE_BYTES, PROXY_TRUSTED_IPS and PROXY_AUTH_SECRET to Env.

Covers extractFeedId, decodeEncodedWords, and parseForwardEmailPayload
including edge cases: missing fields, structured vs text from, headerLines
vs raw headers string, RFC 2047 subject decoding.

Hono's `html` tagged template auto-escapes all interpolated values;
`raw()` is used for the email body which must render as HTML.
This removes the ad-hoc utility and aligns entries.ts with the
same pattern already used in admin.ts.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Make feedId required in generateRssFeed (removes dead /emails/ fallback)
- Hoist loop-invariant conditional and remove intermediate variable
- Extract normalizeAllowedSenders() so JSON and form paths share same logic
- Move escapeHtml to src/utils/html.ts for reuse by admin.ts
- Parallelize the two independent KV puts in feed creation

When Content-Type is application/json, parse the request body as JSON and
return a JSON response instead of redirecting. Useful for automation tools
(e.g. Terraform/OpenTofu provisioning).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Serves each email as a standalone HTML page with a Content-Security-Policy
header, useful for reading emails outside a feed reader and for debugging.
Also updates RSS item links to point to this route.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Parse the From header into name + email parts so the feed library
renders proper RFC 2822 format (email (Name)) in <author> elements.
Also passes feedId to the generator so item links can point to the
upcoming /entries/:feedId/:receivedAt route.

Mirrors the same pattern as cloudflare-email.ts — each provider has its
own adapter that translates provider-specific input into ProcessEmailInput
and delegates to processEmail(). inbound.ts is now a thin HTTP handler.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- email-processor: run email put + metadata get in parallel (saves one KV round-trip per email)
- email-processor: add missing 50-email metadata cap (was unbounded unlike storage.ts)
- email-processor: remove redundant normalizeEmail call on already-normalized allowedSender
- email-parser: strip WHAT-comments and boilerplate JSDoc throughout

Both email providers now work in parallel on the same Worker:
- ForwardEmail: existing POST /api/inbound webhook (unchanged)
- Cloudflare Email Routing: native `email` handler using postal-mime
New files:
- src/lib/email-processor.ts shared business logic (feed lookup,
sender allowlist, KV storage) extracted from inbound.ts
- src/lib/cloudflare-email.ts Cloudflare `email` handler; parses
raw RFC 2822 email with postal-mime, delegates to processEmail()
- src/lib/email-processor.test.ts 9 unit tests
- src/lib/cloudflare-email.test.ts 5 integration tests
Also fixes pre-existing CORS 204 response: c.text("", 204) →
c.body(null, 204) to match Hono's EmptyStatusCode constraint.
To enable: configure Cloudflare Email Routing with a catch-all rule
`*@domain.com` pointing to this Worker.

- Add `typecheck` script (`tsc --noEmit`) to package.json
- Remove conflicting `declare global` from test/setup.ts (superseded
by @cloudflare/workers-types); use `globalThis as any` for test globals
and declare minimal `require` locally to avoid pulling in @types/node
- Cast `createMockEnv()` and `deleteRes.json()` results in admin.test.ts
to silence strict `unknown` / MockKV-vs-KVNamespace errors
