Closes #131. Spec-first companion: HQBase/hqbase-site#57

Summary

v1 clients cannot tell when an owner turns off or disconnects an email domain. This change adds a
domainEnabled boolean to each v1 MailboxAddress.

Changes

  • worker/features/mailboxes/routes.ts: on the /api/v1 path only, read the enabled domain IDs
    with the existing listMailDomains query and set domainEnabled on each address. v2 and the
    admin mailbox list use the same handler but take the unchanged path.
  • api/hqbase-mail-api-v1.openapi.json: add domainEnabled (boolean, required) to
    MailboxAddress, with a description. pnpm api:generate shows no Postman change, because the
    collection has no response examples for mailboxes.
  • CHANGELOG.md: add an entry under a new "Unreleased" section. It says that earlier versions
    do not send the field.

No schema change and no migration. The domain state comes from a second small query on the v1
path, not from a join. A join would change listMailboxesForUser, which v2, MCP, and the admin
mailbox list also use. The MCP list_mailboxes tool returns the v2 mailbox shape, so it
does not change. The admin UI Mailbox type does not use MailboxAddress, so it does not change.

Why the field is required

The server always sends the field, so the schema marks it as required, like other v1 response
fields such as fromName. This tells generated clients that they can read it as a plain boolean.
Each HQBase installation serves its own /api/v1/openapi.json, so an older installation still
serves an older document without the field. HQBase versions before this change do not send
domainEnabled. A client that supports those versions should treat a missing value as true. The
changelog entry says this; the schema description does not, so it does not contradict required.

Tests

  • test/integration/worker/mail-api.test.ts: new test. It adds a second domain with
    is_enabled = 0 and a granted mailbox on it. The v1 list returns domainEnabled: false for that
    mailbox and true for the mailbox on the active domain. The test then turns the domain on and
    checks that the value becomes true. It also checks that each v2 mailbox has exactly the
    existing v2 key set, so the test fails if domain state leaks into v2. The test removes its rows
    when it ends.
  • The existing exact v1 mailbox response check now includes domainEnabled: true.
  • test/unit/scripts/mail-api-artifacts.test.mjs: checks that the v1 schema lists the field as a
    required boolean and that the v2 Mailbox schema does not get it.
  • I made the new integration test fail on purpose twice. When the server always sent true, it
    failed with mbx_api_off: true where false was expected. When the v2 list got an extra
    domainEnabled key, the v2 key-set check failed. It passes with the real code.

Local results:

  • pnpm code:check, pnpm typecheck, pnpm api:check, pnpm test:architecture: pass.
  • pnpm test:integration: 45 files, 225 tests pass.
  • pnpm test:unit: 954 pass. 11 fail in two compose test files
    (compose-recovery.test.ts, use-draft-autosave.test.tsx) with
    Cannot read properties of undefined (reading 'clear') on localStorage. These files are not
    touched by this change. The cause looks like Node 26's built-in localStorage on my machine.
  • pnpm deploy:dry-run: pass.

Compatibility notes

  • Additive under the v1 rule. Existing clients ignore the new field.
  • domainEnabled shows only the owner's switch. A domain can be active but still not ready (for
    example, receiving_status is pending or degraded). That state is not part of this change.

Summary by CodeRabbit

  • New Features
    • Version 1 mailbox responses now include whether the email domain is enabled in HQBase. Clients can use this to identify disabled or disconnected domains; a missing field in older responses should be treated as true.
    • Version 2 mailbox responses remain unchanged.

Add a required `domainEnabled` boolean to each v1 `MailboxAddress`.
It is true when the address's email domain is active in HQBase, and
false when an owner turns the domain off or disconnects it.

HQBase already stops receiving and sending for a domain that is not
active, but v1 clients had no way to see that state. The admin domains
API is outside the v1 contract, so native clients kept showing mailboxes
on disabled domains as usable.

The field is additive under the v1 rule that clients ignore unknown
response fields. v2, MCP, and the admin mailbox list are unchanged.

Keep the schema description to what the field means. The note that
earlier versions do not send the field now lives in the changelog.

Check the full v2 mailbox key set so the test fails if domain state
leaks into v2.

📝 Walkthrough

Walkthrough

The v1 Mail API now reports whether each mailbox address’s domain is enabled. The v1 schema and tests include the field. The v2 mailbox response remains unchanged.

The v1 route loads enabled domain IDs and adds domainEnabled to each serialized address. The schema requires the boolean field. Tests check the enabled and disabled states and confirm the v2 response shape remains unchanged. The changelog says clients should treat a missing field as true.

Priority: ➖ Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature · Severity of issue fixed: Medium

Suggested reviewers: bermanto

Merge Risk: 🔵 Low · up to 3f75b

The v1 mailbox list has an avoidable global query. Its performance impact is currently uncertain; the change is mergeable with owner awareness and a scoped-query follow-up.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 3f75b

The new field remains limited to mailboxes a caller may list. The main risk is that each v1 listing now reads the entire domain table, which could increase database load as installations grow.

Retained concerns

  • Low · security · inferred: Every authenticated v1 mailbox listing performs an unscoped read and sort of the domain table, including when no mailboxes are visible to the caller. Repeated requests could amplify database work and affect availability if the table grows.
Security review details

Security Blast Radius

  • inferred — A caller able to make v1 mail:read requests can trigger the full domain-table query repeatedly. The response exposes the resulting state only for mailboxes returned by the existing access-scoped query; practical resource impact remains unmeasured.

Trust Boundaries and Controls

  • observed — The handler still requires a mail:read principal before accessing data. Non-owner mailbox visibility is determined by grants or the existing admin role; the added response mapping does not return unrelated domain records.

Resilience and Maintainability Implications

  • inferred — The full-table read adds avoidable database work to the v1 request path and can prevent a mailbox response if that additional read fails.

Hardening Proposals

  • proposed — Fetch only the enabled states needed for visible mailbox domain IDs, and skip the domain read when no mailboxes are returned.

The requested query restriction is supported. The current v1 path reads and sorts all rows from mail_domains for every reachable request, including requests that return no mailboxes. The query does not use the mailbox domain IDs or a WHERE clause.

However, the available evidence does not establish that the global table is large enough to make this a major performance issue. Downgrade the severity to a minor performance issue while restricting the domain query to the returned mailbox IDs.
