memory: waterland-studio upstream fixes landed, container stays pinned

waterland-dev merged PR #5 (main now 464dfc2), fixing both landmines at
source: the gpu extra declares cupy-cuda12x[ctk], and the renderer spawns
sys.executable -m waterland.cli instead of re-entering uv mid-job.

The running container deliberately stays on 8025366. Its own [ctk] install
and UV_NO_SYNC/UV_OFFLINE pins already neutralise both defects, so a rebuild
would buy reliability that is already present — and the project is in
wind-down. Both guards are kept rather than dropped: the header requirement
is a property of this slim image, not of the upstream extra, and the uv pins
are now cheap defence-in-depth against any future path that re-enters uv.

Also records waterland-dev's confirmation of the unbounded job-store growth
and the operator's green-light on their startup-rehydrate fix. That PR
merging is the rebuild trigger: one update.sh run lands the rehydrate and
464dfc2 together. Marks the inbox drained.

 - **🟢 FLEET `.internal` DNS — LIVE 2026-08-19.** `<host>.<site>.internal`, sites `ana`/`esh`/`nh3`. `dns/internal.yaml` is the source of truth; `scripts/dns-sync.py` reconciles the three AdGuard resolvers (diff → prompt → apply, idempotent). 42 names resolving from all three sites. **Colo got its first resolver ever** (`stacks/adguard-ana/`, API on **8053** not 8080, no blocklists by design) — before this, ana-docker resolved straight against `1.1.1.1`. Auth = a dedicated `infra-ops` AdGuard user, password vaulted `nh3-dev/adguard-infra-ops-password`. **⏳ TWO OPEN, both operator's to schedule:** (a) colo hosts still point at `1.1.1.1` so they do not yet *use* the new resolver — repointing a site's DNS is a separate change; (b) the static-v6 convention (each server at its site's `/64` with low bits echoing the v4 octet, `esh-docker-vm` → `…::45`) is **proposed, not ruled on**. The `v6:` column is empty and correct — no fleet host has a global v6 address yet. → `persistent-memory.d/2026-08-19-fleet-internal-dns.md`

Upstream `main` is now `464dfc2` (PR #5 fixes the uv-prune and CUDA-header landmines at source); **the container deliberately stays on `8025366`** and keeps its `[ctk]` install + `UV_NO_SYNC`/`UV_OFFLINE` pins as defence-in-depth. **⏳ NEXT: when the rehydrate PR merges, one `update.sh` on irv-ml1 lands it and `464dfc2` together** — that merge is the rebuild trigger.

 - **🟢 HOMEPAGE — cleaned + themed (Australis Skyfall).** Three real defects fixed (UltraSeedbox on all tabs, Uptime Kuma double-rendered, fiction column counts), AI tab reordered by clickability, then themed from the operator's Skyfall handoff bundle with a background generated by **Arbo** (`t2i-ui-background`, job `13f0891f4e42`). ⚠ **After any recreate the tab bar/wallpaper/i18n vanish for up to ~an hour and then return on their own — do not chase it.** ⚠ CSS is served per-request: a theme change needs a **reload**, not a recreate, and candidate CSS can be injected live via Playwright for seconds-long iteration. → `persistent-memory.d/2026-08-19-homepage-skyfall-theme.md`
