Docs: system pages realigned to live ground truth; sibling-vault overlap census

Census against serverAppConfigs-docs + read-only ssh probes on both boxes
(2026-10-18). Corrections to OURS, flags only for THEIRS:

- Hardware drift: RTX 3090 moved dankserver->dankclaw 2026-09; dankserver
  now 2x Radeon AI PRO R9700 (Ryzen 7 7700X stays), 246 GiB RAM, no swap;
  dankclaw 121 GiB RAM + 64 GiB swap. Served: frank-archon radiance TP=2
  (:7770 dankserver), frank-dragoon halogen NATIVE v2 (:7770 dankclaw
  iGPU), frank-zealot llama.cpp PrismML Ternary-Bonsai-2-27B PQ2_0
  (:7771 dankclaw, 3090). Kernel 7.0.0-38 both; dankclaw :7770 no auth.
- Gitea: gitea-caddy quadlet retired (fleet Caddy fronts the domain);
  data tree moved to /home/dank/Containers/gitea/ (2026-09-01 standard),
  /opt/gitea is a do-not-use leftover; LAN IP + live domain.
- pi-era pages (core/settings, pi/models + role tables) demarcated as
  ARCHIVE with banners; llama-cpp fleet note modernized.
- AGENTS.md machine-facts table corrected (it still routed prod warnings
  at frank-default-large).

Their-side staleness flagged in the changelog entry for the operator,
not edited: OMP Harness thresholdPercent 70 (live is 95), Ubuntu 24.04
OS table, 2026-09-03 stack mapping, superseded pi-KB backlink.

 # Pi Configuration
 
-Documentation for the pi coding agent installation on ](../system/index.md).
-Everything here is configured locally on the workstation; the LLM providers are the
-two llama.cpp servers (Dankserver, Dankclaw).
+> **Archive note (2026-10-18).** Most pages in this directory document the retired
+> **pi** harness (settings.json / models.json, `frank-default-*` endpoints, verified
+> 2026-08-28). The live harness is **omp** — its config is `agent/config.yml` +
+> `agent/models.yml` in this repo, the current fleet endpoints are on
+> [System hosts](/system/index.md), and omp-specific knowledge lands in pages like
+> [OMP Status Line Customization](/pi/statusline.md) below. Read pi pages as
+> historical records, not current state.
