docs: index the kdump/rasdaemon design

Design for capturing post-mortem and hardware-error evidence on fleet
nodes: kdump (crashkernel=256M, dump to /var/crash on the unencrypted
root — never the LUKS data partition, so the crash kernel never handles
key material; makedumpfile-compressed, keep-2 retention) and rasdaemon
(EDAC/ECC events into sqlite on the same root).

Deliberately phased: phase 1 = capture on the image + bootstrap backfill
for existing nodes (kernel cmdline can't travel by OTA; takes effect on
next reboot); phase 2 = a read-only system.diagnostics surface in the
UI, only after a fleet node has produced a real dump.

Four decisions flagged in the doc: hang-capture on/off (recommended ON
— a wedged kiosk is useless anyway, and this turns every freeze into
evidence + self-reboot), crashkernel size, backfill timing, and phase-2
scope. Implementation touchpoints listed (Dockerfile.rootfs,
auto-install.sh:1810 cmdline, kdump-tools config, bootstrap, lifecycle
gate assertions).

+# kdump + rasdaemon — post-mortem and hardware-error capture (#144)
+
+Status: DRAFT for review
+Owner: node image (image-recipe) + lifecycle gate
+Issue: #144 — "Configure kdump and rasdaemon for troubleshooting"
+
+## The problem
+
+When a fleet node hard-locks or a memory stick starts failing, today we get
+nothing: a frozen kiosk is power-cycled and the evidence is gone; a DIMM
+throwing correctable ECC errors for weeks is invisible until it starts
+corrupting things. Two standard kernel mechanisms capture this evidence:
+
+- **kdump** — reserves a small crash kernel at boot; on a kernel panic (or,
+  configured so, a hang) the running kernel hands the machine over to the
+  crash kernel, which writes a compressed dump of memory to disk and
+  reboots. The node comes back by itself *and* leaves a post-mortem.
+- **rasdaemon** — a userspace daemon that records hardware error events
+  (correctable/uncorrectable ECC per DIMM, PCIe AER) from EDAC/sysfs into a
+  sqlite database: persistent evidence of degrading hardware with no crash
+  required.
+
+## Facts the design rests on
+
+- Installed-disk layout (auto-install.sh): BIOS boot 1MiB · EFI 512MiB ·
+  **root ext4 30GiB, unencrypted** · data (rest, LUKS).
+- The data partition is LUKS and unlocked late by the node itself — the
+  crash kernel must never be asked to handle key material.
+- The installed system's kernel command line is written by
+  auto-install.sh:1810 (`GRUB_CMDLINE_LINUX_DEFAULT="quiet splash …"`).
+- Packages land via `Dockerfile.rootfs` (trixie) with `systemctl enable`
+  in the same RUN block (nginx/tor/avahi pattern).
+- Kernel cmdline cannot be changed by OTA — it lives in GRUB. Existing
+  nodes need a backfill step (bootstrap) plus a deliberate reboot.
+
+## Design
+
+### kdump
+
+- **Packages:** `kdump-tools kexec-tools` added to Dockerfile.rootfs.
+- **Command line:** append `crashkernel=256M` to
+  `GRUB_CMDLINE_LINUX_DEFAULT` in auto-install.sh. 256M covers the capture
+  kernel plus makedumpfile on the fleet's 16–64GB amd64 machines (~1–2% of
+  RAM reserved, permanently). The arm image (RPi, config.txt boot) is out
+  of scope for phase 1.
+- **Dump target:** `local filesystem /var/crash` — on the unencrypted 30GiB
+  root, deliberately *not* the encrypted data partition. No key handling
+  in the crash initramfs, no dependency on the node's own unlock logic.
+- **Core collector:** `makedumpfile -l --message-level 1 -d 31`
+  (compressed, zero/free pages excluded) — a dump lands at roughly 5–15%
+  of RAM, i.e. ~1–2 GiB on a 16 GiB machine.
+- **Retention:** keep the **2 newest** dumps only. A small systemd timer
+  (or kdump-tools' `KDUMP_POST_SCRIPT`) prunes older vmcores; a full root
+  partition is already caught by disk_monitor's usage tracking. Two dumps
+  ≈ 4 GiB worst case on 30 GiB root — safe.
+- **When to dump — the deliberate trade-off (decision needed):**
+  - Baseline: dump on real panics (`kernel.panic` path) — no behavioral
+    change to a wedged node.
+  - Recommended for this fleet: also enable hang capture
+    (`kernel.hung_task_panic=1`, hardlockup via NMI watchdog). A kiosk
+    that hard-locks is useless until power-cycled anyway; converting the
+    hang into "dump + automatic reboot" turns every freeze into evidence
+    *and* self-heals the node. Cost: a genuinely-busy-but-alive machine
+    that trips the watchdog reboots — the threshold is kernel-default
+    conservative (40s), so this should be rare.
+
+### rasdaemon
+
+- **Packages:** `rasdaemon`; `systemctl enable rasdaemon` in the
+  Dockerfile.rootfs enable block (same pattern as nginx).
+- **Storage:** its default sqlite DB at
+  `/var/lib/rasdaemon/ras-mc_event.db` on the unencrypted root.
+- **Human access today:** `ras-mc-ctl --summary` / `--errors` over SSH.
+  No UI in phase 1.
+
+### Surfacing (phase 2 — separate follow-up, not in this cut)
+
+A small read-only `system.diagnostics` surface: last-crash timestamp and
+vmcore sizes from `/var/crash`, plus ECC error totals per DIMM from the
+rasdaemon DB — shown in Settings → System. Deliberately deferred: capture
+first, UI once there is something to show and a node in the fleet has
+actually produced a dump.
+
+### Existing nodes (phase 1.5 backfill)
+
+The OTA cannot change the bootloader. Bootstrap (which already delivers
+fixes to existing nodes) appends `crashkernel=256M` (and the chosen
+panic/hang params) to `/etc/default/grub` on machines that don't have it,
+and enables `rasdaemon` via the node's package install path. **Takes
+effect on the next reboot** — the operator reboots nodes when applying the
+release; no special ceremony needed beyond that.
+
+## Testing
+
+- Image: the new packages appear in the ISO; QEMU boot smoke
+  (build-iso-release.sh stage 5) still green.
+- Lifecycle gate additions (bats, archi-dev-box first): `kdump-config show`
+  reports a loaded crash kernel reservation; `systemctl is-active
+  rasdaemon`; `/etc/default/grub` carries `crashkernel=`.
+- Live drill (once, on archi-dev-box, not in the gate): trigger
+  `sysrq c` → vmcore appears in `/var/crash`, node reboots itself,
+  second boot is clean. Keep this manual — it reboots the box.
+
+## Implementation touchpoints
+
+1. `image-recipe/build/auto-installer/Dockerfile.rootfs` — packages +
+   `systemctl enable rasdaemon`.
+2. `image-recipe/build/auto-installer/installer-iso/archipelago/auto-install.sh:1810`
+   — append `crashkernel=256M` (+ hang params if approved) to
+   `GRUB_CMDLINE_LINUX_DEFAULT`.
+3. `kdump-tools` config: `/etc/default/kdump-tools` (dump target
+   `/var/crash`, core_collector line, `KDUMP_POST_SCRIPT` or timer for
+   retention).
+4. Bootstrap backfill for existing nodes.
+5. `tests/lifecycle` — presence assertions (crash kernel reserved,
+   rasdaemon active).
+
+## Decisions needed before implementation
+
+1. **Hang capture on or off?** Recommended ON (`hung_task_panic=1` +
+   NMI watchdog): every hard lockup becomes a dump + self-reboot. OFF
+   means dumps only on true panics; wedged nodes still need the button.
+2. **crashkernel=256M vs 320M** — 256M is the common default for
+   16–64GB machines; 320M if we expect large io-heavy kernels.
+3. **Backfill now or new-installs-only?** Recommended: ship the backfill
+   with the next release so the whole fleet gains capture on reboot.
+4. Phase-2 UI surfacing scope — confirm "later" so phase 1 stays small.
