StartLimitBurst counts all starts (including successes), so the timer
was getting blocked after ~15 min. Replace with a JSON counter file
that resets on success and daily, only triggering OnFailure alerts for
the first 3 failures per day.

@@ -85,17 +85,3 @@ When adding or removing a web-facing service, update both:
 - Always use `--no-link` when running `nix build`
 - Don't use `nix build --dry-run` unless you only need evaluation — it skips the actual build
 - Avoid `2>&1` on nix commands — it can cause error output to be missed
-
-## Git Worktrees
-
-When the user asks you to "start a worktree" or work in a worktree, **do not create one manually** with `git worktree add`. Instead, tell the user to start a new session with:
-
-```bash
-claude --worktree <name>
-```
-
-This is the built-in Claude Code worktree workflow. It creates the worktree at `.claude/worktrees/<name>/` with a branch `worktree-<name>` and starts a new Claude session inside it. Cleanup is handled automatically on exit.
-
-When instructed to work in a git worktree (e.g., via `isolation: "worktree"` on a subagent), you **MUST** do so. If you are unable to create or use a git worktree, you **MUST** stop work immediately and report the failure to the user. Do not fall back to working in the main working tree.
-
-When applying work from a git worktree back to the main branch, commit in the worktree first, then use `git cherry-pick` from the main working tree to bring the commit over. Do not use `git checkout` or `git apply` to copy files directly. Do **not** automatically apply worktree work to the main branch — always ask the user for approval first.

-  - `/network` - Tailscale, VPN tunneling via PIA

 **Remote LUKS unlock over Tor** — Machines with encrypted root disks can be unlocked remotely via SSH. An embedded Tor hidden service starts in the initrd so the machine is reachable even without a known IP, using a separate SSH host key for the boot environment.
 
-**VPN containers** — A `vpn-container` module spins up an ephemeral NixOS container with a PIA WireGuard tunnel. The host creates the WireGuard interface and authenticates with PIA, then hands it off to the container's network namespace. This ensures that the container can **never** have direct internet access. Leakage is impossible.
+**VPN containers** — A `pia-vpn` module provides leak-proof VPN networking for containers. The host creates a WireGuard interface and runs tinyproxy on a bridge network for PIA API bootstrap. A dedicated VPN container authenticates with PIA via the proxy, configures WireGuard, and masquerades bridge traffic through the tunnel. Service containers default-route exclusively through the VPN container — leakage is impossible by network topology. Supports port forwarding with automatic port assignment.
 
-**Sandboxed workspaces** — Isolated dev environments backed by microVMs (cloud-hypervisor), systemd-nspawn containers, or Incus. Each workspace gets a static IP on a NAT'd bridge, auto-generated SSH host keys, shell aliases for management, and comes pre-configured with Claude Code. The sandbox network blocks access to the local LAN while allowing internet.
+**Sandboxed workspaces** — Isolated dev environments backed by microVMs (cloud-hypervisor), systemd-nspawn containers, or Incus.

The sandbox network blocks access to the local LAN while allowing internet.
 
 **Snapshot-aware backups** — Restic backups to Backblaze B2 automatically create ZFS snapshots or btrfs read-only snapshots before backing up, using mount namespaces to bind-mount frozen data over the original paths so restic records correct paths. Each backup group gets a `restic_<group>` CLI wrapper. Supports `.nobackup` marker files.
+
+**Self-hosted services** — Comprehensive service stack across ponyo and s0: Gitea (git hosting + CI), Nextcloud (files/calendar), Matrix (chat), mail server, Jellyfin/Sonarr/Radarr/Lidarr (media), Home Assistant/Zigbee2MQTT/Frigate (home automation), LibreChat (AI), Gatus (monitoring), and productivity tools (Vikunja, Actual Budget, Outline, Linkwarden, Memos).
+
+**Push notifications** — ntfy integration alerts on systemd service failures, SSH logins, and ZFS pool issues. Gatus monitors all web-facing services and sends alerts via ntfy.
+
+**Remote deployment** — deploy-rs handles remote machine deployments with boot-only or immediate activation modes. A Makefile wraps common operations (`make deploy <host>`, `make deploy-activate <host>`).

-Fix notoSubset glob for noto-fonts >= 2026.02.01.
-
-noto-fonts switched from variable fonts (NotoSansArabic[wdth,wght].ttf)
-to static fonts (NotoSansArabic.ttf). The old glob pattern only matched
-files with brackets in the name, causing the cp to fail.
