chore: adopt pre-existing working-tree state before trunk merge

Uncommitted machine/session edits (live config, models, docs drift) were
blocking the merge of origin/main. Committed as-is to preserve them; the
merge that follows resolves overlapping prose files toward upstream
canonical, with local variants recoverable from this commit. Pre-merge
copies also in .AGENTTRASH/pre-merge-2026-10-18/.

 # 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.
 
 ## Configuration Files
 
 - [Pi Settings System (settings.json)](/core/settings.md) — Main `settings.json` reference. Providers, models, packages, subagent overrides.
 - [Pi Models Configuration](/pi/models.md) — `models.json` reference. Provider definitions, model specs, endpoints.
+- [OMP Status Line Customization](/pi/statusline.md) — How presets, composer shapes, and segment arrays actually interact; the fleet's tuned bar.
