674ad25662 Move to escapement.warehack.ing; fix GFM tables in MDX
The landing page's headline results table was rendering as a paragraph of raw
pipe characters. Astro applies remark-gfm to .md but it wasn't reaching the MDX
pipeline, so every .md page rendered tables fine and only index.mdx was broken —
which is exactly why it went unnoticed. mdx({remarkPlugins:[remarkGfm]}) fixes it.

cuckoo.warehack.ing stays as a permanent redirect; it was live briefly.

3b505644b2 Kernel release 6.18.38-rt-cuckoo+: reproducible build, guarded installer
Rebuilt with KBUILD_BUILD_USER/HOST/TIMESTAMP pinned. Without them the kernel
bakes the builder's user@hostname and wall-clock build time into /proc/version,
which publishes operator identity in a public artifact and makes the build
unreproducible. Pinned, anyone can rebuild and diff the bytes — the only trust
story available for an unsigned community kernel.

The installer refuses to run on anything but a Pi 4, refuses a mismatched
image/modules pair (vermagic failure means no /dev/pps0 on a kernel that
otherwise boots fine — silent and miserable to debug), verifies SHA256SUMS,
never touches kernel8.img, and leaves rollback as deleting one config.txt line.

Boot-tested on the Pi: Stratum 1, 273 ns offset, PPS handler confirmed NOT
threaded. Binaries ship as release assets, not in git.

6881489bf6 The Cuckoo Escapement: field report, kernel patch, dashboard
What the Raspberry Pi time-server guides get wrong on a Pi 4, with the
measurements. The headline artifact is a four-line pps-gpio patch: PREEMPT_RT
force-threads IRQ handlers, and pps-gpio takes its timestamp inside its handler,
so the realtime kernel puts a scheduler between the electrical edge and the
clock. IRQF_NO_THREAD takes RMS offset from 2468 ns to 199 ns.

- kernel/     the patch
- dashboard/  live status page (position hidden by default)
- docs-site/  the write-up (Astro/Starlight, brass, no tutorial section)
