  v0.46.1 Stable

  The alias index no longer costs a user-visible pause. It was 8.1 seconds on
  the first get_message_security after a restart, paid by whoever asked first.
  Now it is ~1 second of work, and it happens before anyone asks.

  Fixed

  • The index asks the server for the relayed mail instead of reading the
    archive. It swept all 4,602 messages because the alias is only visible in
    headers — but the relay is visible to IMAP SEARCH, and
    origin.resolve returns relayed only when the From domain is a trusted
    relay. So SEARCH FROM folded over TRUSTED_RELAYS matches exactly the
    messages the sweep could learn from, and excludes only what it would have
    discarded.

    Verified rather than assumed — both built on one connection, same moment:

    	messages read	time	index
    full sweep	4,602	7.5s	82 aliases, 102 pairs
    SEARCH FROM	307	1.0s	82 aliases, 102 pairs

    Byte-identical. resolve still runs on every hit and is not redundant with
    the search: SEARCH matched the relay's name, resolve is what verifies its
    signature, and a message failing that must not enter the index.

    An intermediate version walked the archive newest-first and stopped after two
    batches taught nothing — aliased mail is recent, all 258 relayed messages sit
    inside the newest 1,000. It worked, and it is gone: it still read 2,000
    messages for a 7.3s build, and it needed a heuristic about how far back to
    walk that the search does not.

  • The build runs at startup, in the background. warm_alias_index() is
    called from __main__ after preflight, against the client that lives as long
    as the process — not from __init__, where preflight and the tests would each
    trigger their own. The build takes a lock, so a request arriving mid-build
    waits for the one already running rather than starting a second.

    A zero MAIL_ALIAS_INDEX_TTL still switches the whole thing off, and now
    starts no thread either.
