Two additions:
1. secrets-issuance backup: daily timer snapshots /var/lib/secrets-issuance
to /mnt/library/.secrets-issuance-backup/ as a date-stamped tar.gz,
keeping the last 14 days. Closes the catastrophic-fail-mode where an
LXC 105 loss wipes every client's age key with no recovery path.
Caveat: privileged LXCs that mount /mnt/library can read the backup
(root-uid maps to host root); encrypted-tarball variant is a future
refinement.
2. homelab doctor: 10 invariant checks for an enrolled client — clone
present, sync timer/launchd job active, age key perms, CLI symlinked,
AGENTS.md linked, inventory entry exists, MCP reachable, secrets
/health responds, sops canary decrypts, git creds present. Returns
nonzero on any 'fail'. Useful after enrollment or whenever something
smells off.

Discovered via ARP (MAC 02:E1:73:18:EA:49 from qm config). The Tailscale
FQDN 'homeassistant' is fine for tailscale peers but unreachable from
Netbird peers like republic. lan_ip works from both — Netbird routes
192.168.8.0/24 through hubris.
zimaos (VM 100) remains without lan_ip because its IP wasn't in the
hubris ARP table at audit time and we don't want a network scan. The
zimaos service is still reachable via caddy at zimaos.hubris.network
(verified in 'homelab status' SERVICE column).

Audit against actual netbird+tailscale peer lists:
- hubris is the only LXC-host on Netbird; only workstations + hubris
have netbird entries
- 10 LXCs+VMs have real Tailscale FQDNs: apps, jellyfin, paperless,
gitea, nextcloud, elementsynapse, sophia, mule-images→muleimage,
arriman→arr, haos→homeassistant
- 7 hosts are LAN-only (no mesh block): nfs-export, caddy, claudio-bot,
authentik, plato, mule-photos-new, zimaos
- mac-mini's netbird FQDN corrected to the actual peer name
(mac-mini-234-17.netbird.selfhosted)
Also: bin/homelab host_address() now prefers lan_ip first — universally
reachable from any LAN client and from any Netbird peer via the
192.168.8.0/24 network resource routed through hubris. Mesh FQDNs are
fallbacks for roaming workstations without a fixed lan_ip.
This makes 'homelab status' from republic show all backends 'ok' instead
of falsely reporting them 'down' against unresolvable netbird FQDNs.

End of enrollment, if secrets/gitea-pat.yaml is decryptable with the
just-issued age key (i.e. the operator has already run --finalize-pubkey
from another client), upgrade /etc/homelab-context/git-credentials from
the read-only bootstrap PAT to the write-scoped one. Best-effort: fails
silently if not yet a recipient, with a clear hint about what to do next.
Removes the post-bootstrap manual 'homelab refresh-creds' step from the
common flow; falls back to the documented one-liner for first-bootstrap
clients.

Service keys in inventory use _ for python-attribute friendliness but the
actual systemd units use dashes. Explicit systemd_unit field disambiguates
for MCP tail_log / get_service_status.

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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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

yaml.safe_load + safe_dump stripped every comment from inventory.yaml
on each enrollment, eroding the file's documentation value. New
_inventory_set_age_pubkey / _inventory_remove_host / _inventory_append_host
helpers do line-based edits so comments outside the modified region
survive. inventory.yaml gets its top-of-file conventions block back.
build_host_files.py round-trips cleanly (--check returns 0).

Critical bug — the loop reset age_block_last_idx unconditionally on
every '- path_regex:' line. So after finding the target rule's age
block, encountering the NEXT rule wiped the result and the function
returned False. _grant_shared_secrets / _revoke_shared_secrets both
silently no-op'd because of this.
Fix: break out of the scan once we've collected the target rule's
data. Refactored the remove helper to share a find_target_age_lines
inner so the dangling-trailing-comma fixup uses the same logic.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The remove flow ran 'sops updatekeys' but never edited .sops.yaml first,
so the removed client stayed a recipient on every shared secret —
exactly the opposite of what 'remove' should do. Adds the
_remove_recipient_from_sops_policy / _revoke_shared_secrets helpers
(inverse of the grant-side ones from the previous commit); cmd_client_remove
now resolves the pubkey from inventory before deletion and feeds it
through that pipeline.
Also adds the sudo re-exec pattern so 'homelab client remove' works
from a non-root user (matching cmd_secret / cmd_refresh_creds /
cmd_client_add).

LXCs without a mesh CLI sit on 192.168.8.0/24 which is in the
issuance service's MESH_SUBNETS — they should be able to bootstrap
without netbird/tailscale installed. New third path probes the
issuance /health endpoint directly; if reachable, treat that as
satisfying the mesh precondition.

Adds infrastructure/homelab-context.md as the architecture reference for
the cross-client context + MCP + secrets-issuance system. Updates:
- 105-apps.md: two new ## Stacks sections (homelab-mcp, secrets-issuance)
with their deploy pipelines + a row each in the public-hostname table;
changelog entry.
- auto-deploy.md: both new pipelines added to the table (one repo, two
webhooks, same push); per-pipeline notes covering the clone-per-service
pattern and the deploy.sh self-restart caveat; changelog entry.
- README.md: link to the new infrastructure page.
Operational walkthrough already lives at operations/agent-enrollment.md;
this commit is the architecture side of the same story.

Setting the age_pubkey is half the enrollment; the new client also needs
to be a recipient on shared secrets (hello.yaml, gitea-pat.yaml) to
actually use them. Now --finalize-pubkey:
1. writes hosts.<name>.age_pubkey
2. appends the pubkey to each shared-secret rule in .sops.yaml
(preserving comments via line-by-line edit, not yaml round-trip)
3. runs sops updatekeys -y on each shared file
4. commits inventory + hosts/ + .sops.yaml + secrets/ as one commit
Also: cmd_client_add now re-execs via sudo when invoked as a regular
user (matches the pattern in cmd_secret + cmd_refresh_creds).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds secrets/gitea-pat.yaml (SOPS-encrypted, dtoro PAT with read+write
scopes) so any enrolled client can push to dtoro/Homelab-Docs — not just
where I have SSH. Recipient set = hello.yaml's (hubris, apps, republic);
expand alongside hello.yaml when enrolling new clients.
bin/homelab gains 'refresh-creds': decrypts gitea-pat.yaml, rewrites
/etc/homelab-context/git-credentials with the write token, repoints
git's --system credential helper. Re-execs via sudo for non-root callers
(same pattern as 'homelab secret').
After this lands, 'homelab client add/remove' and wiki edits can run
from any client. The initial bootstrap still needs an operator-supplied
read-only PAT (chicken-and-egg); 'refresh-creds' upgrades the client
to write afterwards.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The systemd sync timer runs git without HOME set, so git config --global
(which writes /root/.gitconfig) is invisible to the timer's process — the
timer fails with 'could not read Username' silently. Switching to
--system writes to /etc/gitconfig which is HOME-agnostic.

The 5-min sync pulls /opt/homelab-context but does not re-install the
CLI. A copy at /usr/local/bin/homelab therefore goes stale after every
CLI fix until someone re-runs bootstrap. Symlinking points
/usr/local/bin/homelab directly at the synced source, so updates land
on the next pull. Doc updated with the one-line migration for hosts
bootstrapped before this commit.

/etc/age/key.txt is 0600 root and /etc/age is 0700 root, so the CLI's
Path.exists() check was returning False under regular users — making the
subcommand look broken when bootstrap had actually written the key fine.
Re-exec via sudo preserves the existing UX (one password prompt, then
plaintext) without loosening the key's perms.

Phase 2 first workstation enrolled. age1vf8... is republic-laptop's

Captures the full enrollment flow validated during Phase 2 rollout: per-OS
dep install (dnf/apt/brew), Gitea PAT prerequisite, DNS gotchas, the

ceremony for new inventory entries, secret grant/revoke, and a
troubleshooting table mapping every failure mode we hit during validation
to the commit that fixed it.

Caddy + split-horizon DNS now resolve these to LXC 105 (via 121).

Hubris is Netbird-only and LXC 105 is Tailscale-only; they share LAN
but not a mesh, so on-host \`curl http://192.168.8.205:9820/issue\`
arrives with source IP 192.168.8.77. In a homelab LAN with no
untrusted devices the trust boundary is reasonable; if that changes
later, narrow this.

git credential helper does exact prefix match including scheme. Hardcoding
https:// breaks for in-LAN clones using http://192.168.8.121:3000 (which

Each non-hubris client needs HTTPS auth against gitea for the initial
context clone (chicken-and-egg: a PAT stored in SOPS can't be fetched
until after the clone exists). Adds a --gitea-token flag that writes
credentials to /etc/homelab-context/git-credentials and points git's
credential.helper at it, so the clone and all future pulls succeed
without prompting.

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.

PhotoPrism rotates its session HMAC key on every container start, so any
auto-deploy that recreated pp-app invalidated in-flight OIDC logins. The
deploy script was force-recreating + image-pulling on each push; pinned
both so pp-app survives a routine code deploy.
Measured cold-cache behaviour: thumbnails ~2ms, HEVC video playback
12-21s TTFB because libx264 transcodes inline and serialised one
ffmpeg at a time. Sibling thumbs unaffected (~2ms during transcode).
With 11/45 .mov files already pre-baked, ~75% of clicks were cold.
Ran `photoprism convert` to bring sidecar coverage to 45/45; previously
cold videos now serve in ~2ms TTFB.

NFS was mounted at /DATA/library, so the icewhale-files trash regex
(^/media/([^/]+)) derived drive=ZimaOS-HD and tried to rename into
/media/ZimaOS-HD/.trash on local ext4 -- cross-device EXDEV from NFS.
Remounting at /media/library makes 'library' its own /media/<name>
segment, so trash resolves to /media/library/.trash on the NFS itself.
Synapse runs on SQLite (not Postgres — Postgres only hosts the
mautrix bridge dbs). Documented the post-disk-full
event_push_actions cleanup that took @admin'\''s phantom count

Rootfs grew to 16 GiB on 2026-05-15. Added bridges section
(mautrix slack/signal/meta/linkedin/whatsapp), synapse-admin
port, Postgres backend note, and operational tips for future
disk growth.
Container had been stopped since 2026-04-21 and was never re-enabled.
pct destroy 109 --purge cleaned up vm-109-disk-0 on local-lvm and the
config file. /mnt/library/syncthing subtree was already empty at the
time of destruction and is retained as an empty dir (no real data to

- hosts/hubris.md: dropped from /mnt/library subtree list, updated
containers/index summary line, added changelog entry
- infrastructure/media-permissions.md: dropped from membership table
and onboarding example, generalised pct-exec gotcha hostname,
added changelog
- vms/100-zimaos.md: dropped from "existing fleet" enumeration
- containers/102-nfs-export.md: dropped from bind-mount sibling list
(7 LXCs now, not 8)
- containers/109-syncthing.md: deleted
