Package calendar is the chassis's `calendar` personality: a CalDAV server and ICS feed publisher over the durable calendar store (chassis/calendar), mounted on the web head under a reserved path prefix (--calendar-path-prefix, default /dav) on every hostname the head serves.

Package contacts is the chassis's `contacts` personality: a CardDAV server over the durable contacts store (chassis/contacts), mounted on the web head under a reserved path prefix (--contacts-path-prefix, default /carddav) on every hostname the head serves.

Package dns implements the chassis's authoritative-DNS head: a personality that answers DNS queries for zones explicitly delegated to this chassis, straight from an in-memory snapshot of the dns_zones/dns_records tables.

Package imap implements the chassis's IMAP head: a personality that serves a tenant's durable mailbox store (chassis/imap) to any IMAP4rev1 client — Apple Mail, Thunderbird, mutt — so a mail client becomes a UI over state that stacks project into the store with txco://imap/* ops.

Package lmtp implements the chassis's LMTP head: a personality that speaks LMTP (RFC 2033) to a colocated Postfix (or any LMTP client) and turns each delivery into a normal txcl envelope.

Package mailmap implements the chassis's "mail-domain accept map" head: a tiny TCP server that speaks the Postfix tcp_table(5) protocol so the edge Postfix can ask the chassis, per recipient domain, "is this an accepted mail domain?" before relaying it to the LMTP head.

Package scheduled is the chassis `scheduled` inlet: a per-period poll loop that drains the scheduled_events store (chassis/scheduled) and fires due events into their tenant's `_scheduled/0` stack.

Package source is the chassis `source` inlet: a per-period poll loop that claims due external-source watchers from the tenant_sources runtime table (chassis/source), opens each (a remote IMAP mailbox today), reads what is new past the source's durable cursor, fires each item into the source's `<stack>/_source/0`, and — once an item's run succeeds — acknowledges it at the source (marks it read, or moves it aside).

Package sweep is the continuation-store janitor: a single periodic background pass that fails abandoned/expired runs, fails runs whose resumer crashed mid-resume, and purges long-dead runs.

Package websocket implements the chassis's `websocket` personality: the long-lived side of an HTTP Upgrade.
