spawnInstance now sets DISABLE_RATE_LIMITS=1 by default so unrelated tests
don't exhaust the shared 127.0.0.1 per-IP bucket. bootHomePlusRemotes/
bootTwoInstances accept an optional { enableRateLimits } that omits the env
for tests that need real enforcement, exposed via the explicit
bootTwoInstancesWithRateLimits() helper for Test #15 (rate-limit assertion).
The original peerInstances comment framed the two-row pattern as a
band-aid for getOurOrigin's https://${DOMAIN} default. After
investigating a clean collapse to one row (PUBLIC_ORIGIN override on
each spawned instance), the deeper coupling surfaces:
- extractDomain() strips port via new URL().hostname, so unique-port
localhost instances all share hostname '127.0.0.1' and the
receiver's attribution guard
extractDomain(user.homeInstance) === extractDomain(fedHeaders.origin)
becomes ambiguous in any multi-remote configuration.
- The homeInstance validator regex /^[a-zA-Z0-9._-]+$/ in auth.ts
rejects ':', so the port cannot be encoded into homeInstance to
disambiguate.
- Eliminating the second row would require a production refactor of
extractDomain (port-preserving), the attribution check (decoupled
from URL), or the homeInstance validator (allow ':') — all out of
scope.
So the harness DELIBERATELY keeps DOMAIN as a per-instance human label
('home.test.local' / 'remoteN.test.local') for stable identity, and the
two peer rows per direction (transport URL + getOurOrigin URL) are
structural to localhost-port test reality, not a band-aid. Comment
rewritten to reflect this. PUBLIC_ORIGIN remains available in
production code for reverse-proxy / dev-without-TLS deployments.
Adds setupFullDeletionFixture (federated user joins remote space, authors 2
messages with reactions, opens 1-on-1 DM with a live observer). Tests #3 (soft
mode: tombstone + dm_members cleared, messages/reactions retained) and #5 (full
mode: tombstone + messages/reactions purged, surviving 1-on-1 DM channel).
Also fixes seedPeer to install both the URL form (outbound lookup on sender)
and the DOMAIN-claim form (inbound auth on receiver) — required because the
test harness's ephemeral http://127.0.0.1 origin and DOMAIN-derived
getOurOrigin() return different strings, while production has them coincide.
This was latent: test #1 (leave mode) skips S2S, so #3 was the first test to
actually exercise the S2S delete path and surfaced the dual-origin gap.
Also fix dbInspect.ts UserRow column aliases: SELECT * returns snake_case
columns (is_deleted, display_name, etc.) but UserRow expected camelCase.
Switch to explicit aliased SELECT so all callers get the documented interface.
