New kernel modules, all wired into `homelab` CLI + tested against live
production where reachable:
- oikos/scheduler.py — Observe stage: HTTP health probes for every
service, disk-usage probes on hubris/strong, writes oikos/state.json
(gitignored — regenerates every run). `homelab service <name> health`
is now cache-first; `--live` forces a fresh probe. Deploys via
oikos/systemd/oikos-scheduler.{timer,service} on LXC 105.
- oikos/drift.py — SOPS-recipient-vs-inventory and lifecycle-consistency
detectors (fully local, no SSH) plus pct-list and Caddy-backend
detectors (best-effort SSH, degrade to an info finding when
unreachable rather than a false drift alarm). Found real, currently-
true drift on first run: republic-laptop's age key granted on every
secret but missing from inventory.yaml, grimmory missing from
hello.yaml's recipients, and an undocumented pve_id 131 on hubris —
recorded in OIKOS.md for the operator, not auto-fixed (each is a
config_mutation/destructive decision).
- oikos/signal.py — the attention layer: raised -> acknowledged ->
acting -> resolved|muted lifecycle, severity-based routing, dedup via
open_signal_for(). `homelab signal list|raise|ack|resolve|mute`.
- oikos/decide.py — the Decide-stage classifier: risk class x blast
radius x ledger-history confidence -> auto-act/escalate. Adds an
action-alias layer (oikos/policy.py ACTION_ALIASES) and auto-infers
service_name from the entity for per-service policy overrides.
`homelab decide <action> <entity>`.
- oikos/approve.py — the escalate route. No dedicated Matrix bot exists
in this homelab, so this is the repo-side half only: request/reply/
grant lifecycle with short-TTL HMAC-signed tokens (new secret
secrets/oikos-approval-hmac.yaml, recipients apps+hubris). Matrix
delivery is Hermes's existing @dtoro:avispero send path (documented
integration contract in the module docstring), not a new bot.
`homelab restart` now mechanically refuses config_mutation/destructive
services without a valid --approval-id, regardless of -y/interactivity.
- oikos/report.py — daily brief + weekly report from signal/approval/
ledger state (no Prometheus yet, so point-in-time counts only).
- plans/2026-07-05-oikos-prometheus-lxc.md — Prometheus is `planned`,
not provisioned: no pve_id is guessed here since Proxmox assigns real
IDs at creation time, and drift already found an unclaimed ID (131) to
investigate first.

Adds the shared kernel modules (oikos/policy.py, oikos/relations.py,
oikos/ledger.py) that let every surface — CLI, MCP, context-card
generator — agree on risk classification and ontology graph walks
from one implementation.
homelab CLI: `service <name> explain|health|docs|log|actions|history`
(Service Console v0), `change preflight <service>`, `node <name>
relations`. Restart and client add/remove now append change-ledger
entries (ledger/*.jsonl, committed alongside the change they record).
mcp/server.py mirrors explain/preflight/get_relations/get_change_history
as MCP tools, card-first so agent orientation is one call instead of
several search_docs/get_page round-trips.
oikos/gen-topology.py now also emits a compact context card per host
and service (oikos/cards/*.md) — identity, blast radius, safe actions +
risk class, doc pointer, recent ledger history.
runbooks/*.md: service health check, config change + deploy, client
enrollment, incident investigation, and the five node lifecycle
transitions (provision/activate/migrate/deprecate/destroy), each with
machine-readable frontmatter (risk class, inputs, verification,
docs-update checklist). Wired into HERMES.md so agents load these
instead of rediscovering topology per-task.

Adds the Oikos agent-OS kernel: oikos/policy.yaml (risk classes +
approval rules for every homelab/MCP command), oikos/ontology.yaml
(8-domain systems model, typed relationships, node lifecycle), and
OIKOS.md (OODA loop operating brief, linked from AGENTS.md).
Extends inventory.yaml with a stable service contract (doc_page,
config_repo, risk_notes) on all 17 services, and a structured
archaeology: section for the 13 destroyed LXCs (was scattered
comments + a narrative table). Fixes stale drift found in the
process: authentik's backend pointed at a retired LXC (124); core
has run on the VPS since 2026-05-31.
Adds oikos/gen-topology.py, generating infrastructure/topology.md
(Mermaid compute/ingress + storage views) from inventory.yaml.
build_host_files.py now carries state/storage/depends_on into
generated hosts/*.yaml.

Unit was hard-coding HOMELAB_MCP_SSH_USER=mcp-reader, overriding the new
code's 'root' default. No mcp-reader user exists on hubris — the key is
authorized for root, with a strict command= wrapper. Also pin
HOMELAB_MCP_HUBRIS_HOST + KNOWN_HOSTS env so the service doesn't depend
on the python defaults staying in sync with the unit.

The systemd unit's ProtectHome=true blocks ~/.ssh access. SSH then had
no place to write known_hosts (StrictHostKeyChecking=accept-new) and
silently produced empty results. Use /etc/homelab-mcp/known_hosts (which
ProtectSystem=strict still allows reading) and StrictHostKeyChecking=yes.
Operator pre-populates the file via:
ssh-keyscan -t ed25519 192.168.8.77 > /etc/homelab-mcp/known_hosts

The 5 management tools (get_service_status, tail_log, list_lxcs,
get_lxc_state, ping_service) were registered with sse but all SSH calls
went to per-host targets via a 'mcp-reader' user that didn't exist
anywhere. New design routes every management call through ONE channel:
LXC 105 -> hubris (SSH key + restricted authorized_keys command), then
hubris pct-execs into the right LXC where needed.
Adds mcp/mcp-reader-shell — a strict allowlist wrapper read from
$SSH_ORIGINAL_COMMAND. Rejects shell metacharacters up front and then
matches against a fixed set of read-only patterns (systemctl is-active/
is-enabled, journalctl -u, pct list/status/config, pct exec for the
same subset). Logged to syslog tag mcp-reader.
Authorized_keys line on hubris:
command="/usr/local/bin/mcp-reader-shell",restrict ssh-ed25519 ... mcp-reader@homelab-mcp

We're nftables-gated to mesh+LAN; the browser-attack threat doesn't
apply, and the default whitelist (127.0.0.1/localhost/[::1] only) blocks
every LAN/mesh client.

The MCP service unit expects port 9810 per the inventory; FastMCP only
binds correctly when we set mcp.settings.host/port before run().

Add the foundation for distributing homelab context to every client
(LXCs, VMs, workstations including republic-laptop, mac-mini, ludo-mini)
with a single source of truth, structured query layer (MCP), and per-client
age-key issuance for secrets:
- inventory.yaml — canonical topology (hosts, services, mesh addresses)
- hosts/*.yaml — per-host identity files generated from inventory by
mcp/build_host_files.py; do not edit by hand
- AGENTS.md — orientation doc symlinked to /root/AGENTS.md on every client
- bootstrap.sh — one-shot enroll (Linux + macOS), clones repo, fetches age
key from issuance, installs sync timer/launchd job, drops the homelab CLI
- bin/homelab — single-binary Python CLI: whoami, list, ssh, pct, logs,
restart, open, status, secret, sync, mcp, client add/remove, nuke
- mcp/server.py — FastMCP server: context tools + read-only management
tools (no mutations exposed); shell-outs use mcp-reader restricted ssh key
- mcp/deploy/ — claudio-monitor-style gitea webhook deploy scaffold for the
MCP service on LXC 105 (ports 9810 mcp, 9811 webhook)
- secrets-issuance/ — per-client age key auto-provisioning over the mesh;
source-IP gated against inventory, with denylist for revoked clients
(ports 9820 issue, 9821 webhook)
- secrets/, .sops.yaml — SOPS recipient scaffolding; the operator fills in
age public keys after Phase 3a generates them
- scripts/sync/ — systemd timer (Linux) + launchd plist (macOS) pulling
/opt/homelab-context every 5 min
Mesh: both Netbird (preferred, 100.122.0.0/16) and Tailscale accepted
during the in-flight migration; no client is gated on completing the move.
