dtoro bb5c0717a1 docs: adopt wiki-hq conventions + separate agent instructions (phases 1-2)
Problem: the narrative docs lacked an enforceable style standard, and
agent-facing instruction (OIKOS/CAVEMAN/CONTRIBUTING) was interleaved with
human content at the repo root.

Change:
- Add .agents/shared/{writing-style,llm-wiki}.md — a lint-checkable prose
  standard (with an imperative-voice exception for runbooks/recipes) and the
  sources/wiki/index/log layer model.
- Move CAVEMAN.md -> .agents/shared/caveman.md,
  CONTRIBUTING.md -> .agents/shared/page-templates.md,
  OIKOS.md -> .agents/OIKOS.md; leave thin root stubs so old links resolve.
- Add .agents/domains/{knowledge,operations}/schema.md; operations schema
  codifies "plans always live in plans/".
- Repoint live references (AGENTS, README, GLOSSARY, OIKOS) and fix OIKOS.md's
  internal relative links for its new depth.

Risk: none to the operational substrate — inventory.yaml, hosts/*.yaml,
oikos/, mcp/, secrets/, bin/ untouched (verified via git status).

Verification: relative-link check across .agents/ clean; substrate churn empty.

Knowledge domain — schema

The knowledge domain is the durable, authoritative current-state documentation of the homelab: one page per node and per cross-cutting system, synthesized from live state and evidence. It answers "what exists and how does it work right now."

It follows the LLM Wiki layer model and the writing-style and page-templates rules.

The narrative / substrate split

The knowledge wiki is narrative. It sits alongside a machine-readable substrate that it describes but never contains. The split is load-bearing: several programs read the substrate at fixed paths, so the wiki reorganization never moves it.

Layer Location Consumed by
Substrate — source of truth inventory.yaml (root) MCP server, homelab CLI, oikos/ scheduler/drift/relations/gen-topology
Substrate — generated host records hosts/*.yaml (root) mcp/server.py (HOSTS_DIR), bin/homelab; written by mcp/build_host_files.py
Substrate — kernel + context cards oikos/ (code, oikos/cards/, oikos/state.json) MCP explain, scheduler
Narrative — synthesized wiki knowledge/wiki/{hosts,containers,vms,infrastructure}/ humans, agents via MCP get_page / search_docs
Evidence — immutable sources knowledge/sources/, investigations/ synthesis into wiki pages

Wiki pages

  • Node pages (knowledge/wiki/containers/<id>-<name>.md, .../vms/<id>-<name>.md, .../hosts/<name>.md) follow the container/host template in page-templates.md: opening definition, ## At a glance, ## Role, service/port map, storage, auto-deploy, ## Related, ## Changelog.
  • Cross-cutting pages (knowledge/wiki/infrastructure/<topic>.md) follow the cross-cutting template: ## Why, ## Components, ## How to apply, ## Gotchas, ## Related, ## Changelog.
  • Each inventory.yaml host entry carries a doc_page: field pointing at its narrative page. Changing where a page lives means updating that field (read by bin/homelab).

The two logs

  • The per-page ## Changelog records infrastructure changes and is machine-parsed (get_changelog, the Oikos ledger). Keep the ### YYYY-MM-DD — title shape.
  • knowledge/log.md is append-only and records documentation-maintenance operations only (restructures, source ingests, lint sweeps): ## [YYYY-MM-DD] <op> | <summary>. It never duplicates the Oikos change ledger (oikos/ledger.py).

Same-session update rule

A change to a node updates every page that references it in the same session — the node page, the section README.md table, the root README.md, the Caddy/DNS/ingress pages, the host page, and inventory.yaml. See page-templates.md.
