- ops/nginx_conf/targetinfo.lua's wildcard-subdomain lookup fallback used
classic LuaSocket (require("socket.unix")) instead of an OpenResty
cosocket. LuaSocket is blocking, and called from an nginx worker it
stalls the ENTIRE worker — every other in-flight connection on it — for
the round-trip to the Node app. Worse, the Node side never
newline-terminated its response, so the old blocking receive() only ever
returned via its read-timeout-then-partial-read fallback, meaning every
single cache-miss lookup paid a fixed timeout penalty while blocking the
whole worker. Replaced with an ngx.socket.tcp() cosocket (unix-domain via
"unix:/path", the only cosocket API this lua-nginx-module ships) and
newline-terminated the Node service's responses so receive() actually
completes instead of timing out. Verified against a live container:
previously this crashed OpenResty's Lua VM entirely
(ngx.socket.unix doesn't exist); fixed version resolves fresh wildcard
subdomains in ~2ms.
- Add gzip compression (`compression` middleware) and far-future
Cache-Control on static assets (7d for vendor libs under
/static-modules, 1h for the app's own /static JS/CSS, which isn't
cache-busted). The admin UI is a traditional multi-page app that loads
~13 separate vendor/app JS+CSS files on every full navigation; previously
none of them were compressed and Cache-Control was `max-age=0` (Express's
default), forcing a revalidation round-trip for every asset on every page
view.

The host scheduler already checked wildcard cert expiry; add the second half of
the scheduler controller — DnsProvider.refreshAllDomains() re-syncs every
provider's domain list (get -> updateDomains, per-provider errors isolated),
scheduled 30s after start and every 24h alongside the cert check.

For deployments on WAN DHCP, operators can declare A records in the DNS section
that the app updates to this box's current public IP every 4 hours (and
immediately on create).
- utils/public_ip.js: getPublicIp() queries external echo services (ipify +
fallbacks, configurable) with pure isIPv4/extractIp helpers.
- utils/dns_records.js: pure planARecordUpdate() reconciliation decision.
- models/dns_provider.js: Domain.upsertARecord(name, ip) — provider-agnostic
upsert via getRecords + deleteRecordById + createRecord (createRecord alone is
not a reliable cross-provider upsert). Apex ('@') handling added to each
provider (CloudFlare uses the domain name, Porkbun an empty name, DigitalOcean
'@') via a new DnsApi.apexName().
- models/dynamic_record.js: DynamicRecord model (deterministic id per host,
apply()/refreshAll()), registered + ModelPs-wrapped for live UI updates.
- services/dynamic_dns.js + conf: 4h scheduler mirroring host_scheduler.
- routes/dns.js: /dynamic CRUD + /dynamic/ip, gated to domain managers/admins.
- views/dns.ejs: "Dynamic A Records (WAN IP)" card with add form + list.
- test/unit/dynamic_record.test.js: public-IP parsing + reconciliation logic.
Verified end-to-end against a live Porkbun domain (create, idempotent, IP-change,
cleanup) plus unit suite (111 pass).

A *.example.com wildcard host now chooses between two routing modes:
- wildcard_matchAny=false (default): only subdomains explicitly defined
in redis route; undefined subdomains get no match (406)
- wildcard_matchAny=true: any subdomain catches-all to the wildcard
parent host, preserving the previous behavior
The gate lives in the host_lookup socket service, which is only reached
for domains missing a direct redis entry, so defined children and
**-style hosts are unaffected. Adds the matching-mode selector to the
host add/edit form, shown for wildcard hosts.
Note: existing wildcard hosts have no wildcard_matchAny field and so
default to the stricter "only defined" mode until re-saved.
