dtoro b5c1247093 docs: streamline & consolidate the tree (phase 6)
Problem: after the wiki-hq reorg, agent-instruction and human-doc domains
were still scattered across the repo root, with three now-redundant stub
files cluttering it. The organizing principle wasn't visible in the layout.

Change — enforce three clear buckets:
- .agents/  = how agents operate: OIKOS.md, HERMES.md (moved from root),
  shared/ conventions, domains/ schemas, skills/, and operations/ (operator
  cheatsheet + enrollment + hermes-agent, moved from root).
- knowledge/ = what exists + evidence: wiki/, GLOSSARY.md, and sources/ now
  including investigations/ (incident records are evidence/sources).
- root = substrate + two entry points (AGENTS.md, README.md), plus plans/
  as its own design-intent domain.

Moves:
- investigations/ -> knowledge/sources/investigations/ (incl. archive/, index).
- operations/ -> .agents/operations/.
- HERMES.md -> .agents/HERMES.md.
- Deleted unreferenced root stubs CAVEMAN.md, CONTRIBUTING.md, and OIKOS.md
  (its 7 remaining linkers repointed to .agents/OIKOS.md).

Consumers updated:
- inventory.yaml doc_page (agent-enrollment) + regenerated hosts/*.yaml + cards.
- tools/setup-hermes-soul.sh and bootstrap.sh (x2) -> .agents/HERMES.md.
- bin/homelab help string -> .agents/operations/hermes-agent.md.
- knowledge/operations schemas, llm-wiki, page-templates, incident-investigation
  skill, AGENTS.md/README nav -> new investigations/operations paths.
- All markdown links rewritten via the path-resolving mapper.

Left in place (substrate/executable/separate-domain): hosts/, ledger/, tools/,
plans/, oikos/, mcp/, secrets/, bin/, inventory.yaml.

Verification: docs-lint at baseline (2 intentional cross-repo refs, no new
breakage); gen-topology.py --check exit 0; build_host_files.py idempotent; all
doc_page targets resolve; Hermes provisioning scripts point at the new path.

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/ (references + 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.
