+The stack is deliberately small: `git` plus the Python 3 standard library. There is no `pip`, Node, Go, or CUE, and compose files are hand-authored — no code generation.
 
 ## Core features
 
-- **Single entrypoint on the local checkout** — `apex` always acts on the checkout it runs from; there is no `<node>` argument to pass.
-- **Explicit identity from `node.env`** — [node identity](/apex/glossary#node-identity) is declared per node in `node.env` (`APEX_NODE_FQDN`, `APEX_NODE_HOST`, `APEX_SUBNET`); the framework assumes no particular domain, and the short node `name` is just the first label of the host.
-- **Four-pillar node repositories** — every node repository follows the same shape: the pinned `commons/` submodule, node-local [proprietaries](/apex/glossary#proprietaries), the node's [compositions](/apex/glossary#compositions), and its `node.env`.
-- **Proprietary overlay** — node-local proprietaries are [overlaid](/apex/glossary#overlay) over the shared actions; commons holds only what every node shares.
-- **Tiered storage with privilege isolation** — standardized storage [tiers](/apex/glossary#tier) with per-project privilege isolation.
-- **Shared core composition** — the [core composition](/apex/glossary#core-composition) (`compositions/apex/docker-compose.yml`) is `${env}`-parameterized and included in every node's compositions.

Each layer is applied by an [action](/apex/glossary#action) and is therefore reproducible and re-runnable.
 
 ## Privilege isolation {#privilege}
 
-Every project runs as its own locked `noroot-<project>` system user; shared storage is group-writable with the sticky bit so projects can exchange files without being able to delete each other's. The full mechanism — users, groups, and the ownership matrix — is described in [Concept: Tiered storage](/apex/concepts/tiered-storage).

+`apex configure/ufw` applies the node's firewall from the `configs/ufw/` pillar in three parts:
 
-- **Host rules** (`configs/ufw/host/host.rules`) — plain `ufw` commands, one per line, applied in order.
-- **Kernel-level rule blocks** (`configs/ufw/host/before.rules`, `after.rules`) — injected into `/etc/ufw/before.rules` and `/etc/ufw/after.rules` as managed marker blocks. Injection is **self-healing**: every previous managed block — including blocks left by predecessor tooling — is removed before the fresh block is inserted after ufw's `# End required lines` anchor, and a timestamped `.bak` of the target is kept beside it.
-- **Container rules** (`configs/ufw/docker/*.rules`) — applied through `ufw-docker`, which translates them into rules that survive Docker's own iptables manipulation. `configure/base` installs the helper to `~/.local/bin/ufw-docker`.

-Missing configuration is an error, not a silent skip: an absent `docker/` or `host/` directory exits `66` when its counterpart exists, and a missing `/etc/ufw` target file aborts the run. The action finishes with a reminder that `ufw` must be restarted to take effect — and that the SSH port must be allowed first.

 ## Intrusion detection {#crowdsec}
 
-`apex configure/crowdsec` installs CrowdSec through its official installer when `cscli` is absent, renders everything under `configs/crowdsec/` into `/etc/crowdsec/` (acquisition sources, parsers, bouncer configuration), and installs the `crowdsecurity/linux` and `crowdsecurity/traefik` collections. When the node's configs include a firewall-bouncer configuration, the matching bouncer package is installed as well, closing the loop from detection to blocking.

 ## Observability {#observability}
 
-Observability is an **outbound push**, not an exposed route. The optional `alloy` core service (Grafana Alloy, one agent per node) collects host metrics (a `node_exporter`-equivalent), container metrics (cadvisor), the systemd journal, and docker container logs, and pushes them to a **central** Prometheus and Loki that live on a designated node — the metrics via `prometheus.remote_write` to `APEX_PROM_PUSH_URL`, the logs via `loki.write` to `APEX_LOKI_PUSH_URL`. Both targets are authenticated with HTTP basic auth using `APEX_OBS_BASIC_AUTH_USER` / `APEX_OBS_BASIC_AUTH_PASS`. Because the push is outbound, Alloy attaches to the `direct` network (which has egress) rather than the `internal` `enclave`; there is no node-local log store and no `/loki` route to protect.

 ## Secrets boundary {#secrets}
 
-- Secrets live only in per-project `.env` files, which are **symlinks into tier-1 storage** — outside the repository working tree and covered by `.gitignore` (`**/.env`).
-- Each node repository documents its expected keys in `SECRETS.md`; the file documents names, never values.
-- Committed configuration (`apex.env`) is restricted to non-secret scalars.
-- The shared composition marks critical secrets with `?error`, so a missing value fails fast at compose-config time.
-- [Capture-up](/apex/glossary#capture-up) commits are safe by construction: the ignored `.env` links and tier data never enter the git index.

-- `apex --help` lists actions without warnings on the live host.
-- `docker ps` shows the core containers (`apex-traefik`, `apex-socket-proxy`, plus any profile-enabled services) and each project's anchor.
