chore: prepare release v1.8.16-alpha

450 existed as two independent Rust constants (RPC gates vs boot
reconciler) linked only by a "keep in lockstep" comment — updating one
would reopen the disk-fill hole. Move it to crate::constants as the
single source of truth both paths import.

Also raise apps/cuprate/manifest.yml storage dependency and disk_limit
from 300Gi to 450Gi so manifest-driven surfaces (store size, pre-checks)
show the number the gate actually enforces — a user provisioning to the
displayed 300 was refused at an unexplained 450. Catalog regenerated
(cuprate entry re-embedded; still unsigned pending sign-catalog.sh).

 ## Unreleased
 
+## v1.8.16-alpha (2026-09-15)
+
+- App updates refresh and verify the signed catalog before changing containers. A failed refresh or manifest reload cancels the update, and automatic updates wait for a successful refresh.
+- Fixed repeated Mempool update offers: downstream `-archyN` patches now sort above their upstream release, and moving a published image between registry namespaces does not hide a genuine upgrade.
+- Updates inspect installed component versions, refuse known downgrades, skip containers already at the target versions, and verify the resulting versions before reporting success.
+- Added regression coverage for stale catalogs, matching versions, publisher namespace changes, stack component updates, and keeping running containers untouched when no upgrade is needed.
+
+## v1.8.15-alpha (2026-09-13)
+
+- Cuprate is presented as one user-facing app in My Apps, including its UI launch button; the generated dashboard companion is hidden as an implementation detail instead of appearing under Services.
+- Added regression coverage for Cuprate install and installed-state grouping.
+- Release validation was rerun on the corrected tree before OTA and ISO publication.
+
+## v1.8.14-alpha (2026-09-13)
+
+- **Cuprate gains a first-party companion dashboard.** The Monero node now has a Bitcoin-style status UI, safe app grouping, a 450 GB disk-safety gate, and a restricted RPC that is never exposed as a launch page.
+- **Bitcoin Core Tor enrollment uses the correct protocol identity.** `bitcoin-core` is forwarded on port 8333 and resolves to its own hidden-service directory without disturbing legacy Bitcoin aliases.
+- **GitWorkshop opens Archipelago’s canonical ngit repository by default.** The launcher and registry promotion use the full maintainer/relay/`archy` coordinate, with regression coverage for Companion and browser-tab launches.
+- **Release validation is stricter.** The registry gate now checks the complete canonical source deep link, and the merged candidate passed the full frontend and focused backend test suites.
+
 ## v1.8.13-alpha (2026-09-12)
 
 - **GitWorkshop installs reliably on fresh nodes.** The app is classified as a user-facing app while its install placeholder is being created, so it remains visible under My Apps instead of Services.

+# Mempool frontend DNS recovery
+
+The stock v3.3.1 nginx configuration resolves `mempool-api` only when workers
+start. Recreating the backend can change its Podman address while the frontend
+continues to serve its static page, leaving all API/WebSocket requests offline.
+
+Build and test the derived image before publishing:
+
+```sh
+podman build --pull=never -t source.archipelago-foundation.org/chaum/mempool-frontend:v3.3.1-archy1 docker/mempool-frontend
+python3 scripts/test-mempool-dns-recovery.py
+```
+
+The base is pinned by digest. The wrapper preserves upstream runtime options,
+then repairs all four local API/WebSocket routes after placeholder rendering.
+DNS is cached for five seconds using the container network resolver. Explicit
+rewrites preserve API prefixes and query arguments; backend absence does not
+prevent nginx startup. An unexpected upstream configuration fails startup
+instead of silently omitting the fix.
+
+Use an Archipelago-specific image tag. Do not replace it with a stock upstream
+mirror when updating mempool. Every upstream update must rebuild this wrapper
+and pass the recovery test (backend absent, changed IP, HTTP and WebSocket
+mapping, repeated repair, and frontend restart).
+
+Publish the tested image before publishing the signed app catalog. Both the
+mempool umbrella image mapping and the archy-mempool-web embedded manifest must
+point at the patched image. Keep scripts/image-versions.sh in sync. The frontend
+health check must reach `/api/v1/backend-info` through nginx, not only `/`.

-# ─── archipelago patch ────────────────────────────────────────────────────
-# The stock frontend writes `proxy_pass http://<backend>:8999` with a literal
-# hostname and NO resolver, so nginx resolves the backend IP ONCE at worker
-# start and caches it for the process lifetime. Podman reassigns the backend
-# container's IP whenever it is restarted/recreated (gate, OTA, crash, reboot
-# re-IPAM), after which nginx keeps proxying to the dead IP → /api hangs, the
-# websocket 502s, and the mempool UI shows "offline" until nginx is reloaded.
-#
-# Fix: force per-request DNS re-resolution via `resolver` + a variable in
-# proxy_pass. Because a variable in proxy_pass disables nginx's automatic
-# location→URI rewriting, each block is rewritten to preserve its original
-# path mapping exactly:
-#   /api/v1/ws, /ws → "/"            (var + "/" replaces the whole URI)
-#   /api/v1         → identity       (no-URI proxy_pass passes $uri unchanged)
-#   /api/           → /api/v1/$1     (explicit rewrite, then no-URI proxy_pass)
-# Operates on the __PLACEHOLDER__ tokens so the host/port sed below fills in
-# the concrete values (incl. the `set $mp_backend` line). Idempotent.
-# Resolver address: podman's aardvark-dns answers on the network gateway
-# (e.g. 10.89.0.1), NOT Docker's 127.0.0.11. Read it from resolv.conf so this
