+# Host Naming Discrepancy Report
+
+This report compares the current `modules/hosts` tree against the naming rules for new hosts in `hosts.instructions.md`.
+
+## Rules Checked
+
+- The host directory slug should be the canonical host identity.
+- A directory-backed host should prefer `default.nix` as its main entrypoint.
+- The canonical slug should line up with the primary `hostname` binding, `flake.nixosConfigurations.<slug>`, and `networking.hostName`.
+- A host-local Home Manager module should use the same slug.
+- A standalone Home Manager configuration should prefer the key `"<username>@<slug>"`.
+- Host-local helper module names should be prefixed by the host slug.
+
+## Summary
+
+- Recently normalized: `john-kde`, `omen-nixos`.
+- Hosts that fit the new rules closely: `janus`, `john-kde`, `omen-nixos`, `test-nix`.
+- Hosts with notable discrepancies: `john-p14s`, `soteria`.
+- Approved exception: `john-pc` directory uses immutable deployed slug `john-pc-ubuntu` for exported keys.
+
+## Detailed Discrepancies
+
+### `john-p14s`
+
+- The main host export uses the canonical slug: `flake.nixosConfigurations.john-p14s`.
+- The host-local helper modules are named `p14sConfiguration` and `p14sHardware`, which drop the `john-` prefix and therefore do not use the full host slug.
+- `networking.hostname` uses the correct host value, but the option name differs from the dominant `networking.hostName` spelling used elsewhere in this tree.
+
+### `john-pc`
+
+- Approved exception for immutable deployed hostname:
+- Directory slug is `john-pc`, but exported keys and hostname bindings intentionally use `john-pc-ubuntu`.
+- `hostname` binding, `flake.modules.homeManager.<name>`, and `flake.homeConfigurations` are aligned to `john-pc-ubuntu`.
+- Shared SSH alias intentionally remains `john-pc-ubuntu` in `modules/services/ssh.nix`.
+
+### `omen-nixos`
+
+- No active discrepancy after normalization:
+- The directory slug, `flake.nixosConfigurations` key, host-local module keys, and `networking.hostName` are now aligned to `omen-nixos`.
+
+### `john-kde`
+
+- No active discrepancy after normalization:
+- The directory slug, `hostname` binding, host-local Home Manager module key, and standalone Home Manager key are now aligned to `john-kde`.
+
+### `soteria`
+
+- Naming is mostly coherent across directory slug, `hostname`, `flake.nixosConfigurations.soteria`, and `flake.modules.homeManager.soteria`.
+- The standalone Home Manager export is `flake.homeConfigurations.soteria`, which does not follow the preferred `"<username>@<slug>"` form.
+- The main host entrypoint is `soteria.nix` instead of the preferred `default.nix`.
+
+## No Discrepancy Found
+
+### `janus`
+
+- Directory slug, `hostname`, `flake.nixosConfigurations.janus`, and `networking.hostName` are aligned.
+- The host-local helper module `janus-ca` is clearly prefixed by the host slug.
+
+### `test-nix`
+
+- The single-file host uses the same slug for the file stem, `hostname`, and `flake.nixosConfigurations.test-nix`.
+- It does not define `networking.hostName`, but it does not contradict the slug anywhere else.
+
+## Follow-up Candidates
+
+- Rename `john-p14s` helper module keys to include the full host slug (`john-p14s-*`) if strict slug consistency is desired.
+- Decide whether `soteria` should move to `default.nix` and whether its standalone Home Manager key should include `john@`.
+- If `john-pc-ubuntu` ever becomes changeable, decide whether to rename the directory to match or keep this as a permanent exception.

+
+# Host Definitions
+
+Host files under `modules/hosts` are flake entrypoints, not just loose Nix snippets. Because `modules` is auto-imported through `import-tree` and `flake-file`, files here usually export one or more of these attributes:
+
+- `flake.nixosConfigurations.<name>` for a bootable NixOS machine or container.
+- `flake.homeConfigurations.<name>` for a standalone Home Manager target.
+- `flake.modules.nixos.<name>` or `flake.modules.homeManager.<name>` when a host is split into reusable host-local modules that are then assembled by a nearby entrypoint.
+
+Follow the existing host patterns in this tree:
+
+- Keep the host entrypoint file focused on composing modules into `nixosSystem` or `homeManagerConfiguration`.
+- If a host has substantial machine-specific logic, put that logic in sibling files such as `configuration.nix` or `hardware.nix`, export them as `flake.modules.nixos.<name>`, and have the entrypoint import those modules.
+- For Home Manager only hosts, define `flake.modules.homeManager.<name>` and then expose a matching `flake.homeConfigurations` entry.
+- Prefer composing from shared modules in `self.modules.nixos` or `inputs.self.modules.homeManager` instead of re-implementing shared behavior inline.
+
+Treat host-local data as part of the host definition:
+
+- Keep hardware-specific settings in the host directory, typically in `hardware.nix`.
+- Keep install-time or machine-specific configuration in the same host directory, typically in `configuration.nix`.
+- Keep host-local secret references beside the host and wire them through `sops.defaultSopsFile` and `mysops.hostSecretFile` instead of pointing at unrelated locations.
+- Preserve nearby auxiliary files such as `defaults.json`, fingerprints, public keys, and `secrets.yaml`; these are part of the host contract.
+
+For host-adjacent data files:
+
+- Keep `secrets.yaml` scoped to the host that consumes it; do not reuse another host's secret file as a shortcut.
+- Treat files such as `defaults.json`, `fingerprint`, and `*.pub` as inputs consumed by the host module. Update references together with the data when changing paths or filenames.
+- Avoid moving or renaming these files unless the corresponding Nix references are updated in the same change.
+
+Naming in this tree is not perfectly uniform, so preserve existing interfaces unless the task is explicitly a rename:
+
+- The directory name, exported flake key, and `networking.hostName` may differ.
+- Some hosts export from `default.nix`, while others keep the main definition in a differently named file such as `soteria.nix`.
+- Do not normalize names or move files just for consistency unless the user asks for that structural change.
+
+Naming rules for new hosts:
+
+- Treat the host directory name as the canonical host slug for new work.
+- Prefer `modules/hosts/<slug>/default.nix` as the main entrypoint for a host directory.
+- Use the same slug for the primary `hostname` binding, `flake.nixosConfigurations.<slug>`, and `networking.hostName` unless the task explicitly requires a different deployed hostname.
+- If the host exports a host-local Home Manager module, name it `flake.modules.homeManager.<slug>`.
+- For standalone Home Manager configurations, prefer `flake.homeConfigurations."<username>@<slug>"` so the exported key still carries the host slug.
+- Name host-local helper modules with the same slug as a prefix, for example `flake.modules.nixos.<slug>-hardware` or `flake.modules.nixos.<slug>-configuration`, to make ownership obvious and avoid collisions with shared modules.
+- Keep host-local secrets and auxiliary files under the same host slug directory. Do not point a new host at another host's path just because the contents are similar.
+
+Allowed exception for immutable deployed hostnames:
+
+- If the deployed hostname is externally constrained and cannot change, use that deployed hostname as the canonical slug for exported keys and `hostname` bindings, even if the directory name differs.
+- In that case, keep the exception explicit in comments or reports so future cleanup work does not accidentally rename a live hostname contract.
+
+When working in existing hosts that predate these rules:
+
+- Preserve the current public names by default.
+- If the user asks for a rename or cleanup, update the directory slug, exported flake keys, host-local module names, and `networking.hostName` together in one change so the host identity stays coherent.
+
+Use nearby hosts as composition examples:
+
+- `john-p14s` splits the reusable machine logic into `configuration.nix` and `hardware.nix`, exports `flake.modules.nixos.p14sConfiguration` and `flake.modules.nixos.p14sHardware`, and assembles them from `default.nix`.
+- `janus` defines a host-local reusable module (`flake.modules.nixos.janus-ca`) in the same file that also exports the final `flake.nixosConfigurations.janus` host.
+- `john-pc` is a Home Manager target, so it exports a `flake.modules.homeManager` module and a `flake.homeConfigurations` entry rather than a `nixosConfiguration`.
+- `soteria` combines a NixOS host, a host-local Home Manager module, and host-local secrets in one host directory.
+
+When adding or changing a host:
+
+- Mirror the local style first. Small hosts may define the full configuration inline; larger hosts should split reusable modules out.
+- Keep `let` bindings such as `username`, `hostname`, `flakeDir`, and package aliases near the top when the file already follows that pattern.
+- Add shared behavior by importing existing modules, not by copying option blocks between hosts.
+- If the change affects both system and Home Manager state for a host, update both sides in the same host area when that host already models both.
+
+For reviews and answers, distinguish between these layers:
+
+- host entrypoint wiring in `modules/hosts/...`
+- reusable shared modules in `modules/nixos`, `modules/programs`, `modules/services`, and `modules/users`
+- host-local modules exported from a host directory and then consumed by its entrypoint

+
+# Janus Host Instructions
+
+Use this instruction when changing Janus host wiring, Janus CA material, or the shared Step CA module that Janus consumes.
+
+## Host Intent And Boundaries
+
+- Treat Janus as the homelab certificate authority host. It runs `step-ca` for X.509 issuance, SSH user and host certificates, and mTLS certificates.
+- Assume Janus CA endpoints are private/LAN-only unless the task explicitly changes the exposure model.
+- Keep Janus as a concrete host under `modules/hosts/janus`; keep reusable behavior in shared modules such as `modules/services/step-ca/step-ca.nix`, `modules/services/step-ca/ssh-host.nix`, `modules/features/step-client.nix`, and `modules/features/mtls.nix`.
+- Preserve host identity unless the task explicitly renames the deployed CA: `hostname = "janus"`, `flake.nixosConfigurations."${hostname}"`, and `networking.hostName = hostname`.
+- Keep Janus-specific paths, DNS names, IP SANs, and CA artifacts in the Janus host area or in Janus-specific option values. Do not move them into generic shared modules unless they become a deliberate module interface.
+
+## Required Module Composition
+
+When editing `modules/hosts/janus/default.nix`, preserve this composition unless the task explicitly changes Janus architecture:
+
+- `nixos.lxc` for the container host shape.
+- `nixos.mysops` with `sops.defaultSopsFile = ./secrets.yaml` for host-local encrypted CA runtime material.
+- `nixos.step-ca` to run the CA daemon and render `/etc/smallstep/ca.json` from Nix plus SOPS paths.
+- `nixos.step-client` to install Step trust bootstrap defaults and root CA material.
+- `nixos.ssh-certs` so Janus itself participates in SSH host certificate flow.
+- `nixos.mtls` so Janus can issue and renew its own mTLS certificate bundle.
+
+## Step CA Deployment Pattern
+
+- Prefer structured Nix values rendered with `builtins.toJSON` over hand-written JSON strings for `ca.json`.
+- Prefer the NixOS `services.step-ca.settings` interface for normal `ca.json` settings. Use a `sops.templates`-rendered config only when the rendered JSON needs sops-nix placeholders or runtime secret paths.
+- Keep secret-bearing `ca.json` content rendered through `sops.templates` when it includes values from `config.sops.placeholder`; do not put decrypted private keys, passwords, or provisioner encrypted private-key values directly in the Nix store.
+- Continue using `services.step-ca` for the daemon contract: `enable`, `settings`, `address`, `port`, `openFirewall`, `package`, and `intermediatePasswordFile`.
+- Remember that the NixOS module overrides `services.step-ca.settings.address` with `services.step-ca.address` plus `services.step-ca.port`. Change the high-level address/port options when changing the listener.
+- Keep the intermediate password as a runtime string path from `config.sops.secrets.<name>.path`; do not use a Nix path literal or the password file can be copied to the globally readable Nix store. Do not pass passwords through command-line arguments or environment variables.
+- Account for upstream NixOS service behavior when debugging: the module writes `/etc/smallstep/ca.json`, starts `step-ca.service` as `Type=notify`, sets `DynamicUser = true`, uses `StateDirectory = "step-ca"`, and passes `intermediatePasswordFile` through systemd `LoadCredential`.
+- If `step-ca` cannot read key files referenced by `ca.json`, check sops-nix owner/group/mode and systemd credential handling before loosening permissions. The password file path and CA signing key paths are separate contracts.
+- Keep Step CA runtime state in `/var/lib/step-ca/db` unless the task explicitly migrates storage. If moving away from embedded Badger, document database backup and HA implications.
+- Keep `root`, `crt`, `key`, `ssh.hostKey`, and `ssh.userKey` in `ca.json` pointing at public cert paths or sops-nix materialized secret paths as appropriate.
+- Use an ACME provisioner for automated X.509 issuance, an `SSHPOP` provisioner for SSH certificate renewal/rekey behavior, and the `admin` JWK provisioner for explicit administrative or scripted issuance. Ensure JWK claims include `enableSSHCA = true` when it is expected to sign SSH certificates.
+- Treat Nix and SOPS as the source of truth. If `step ca provisioner add`, `remove`, or `update` is used for investigation, copy the intended result back into Nix/SOPS and reload or restart `step-ca`; do not leave live `ca.json` drift on the host.
+- Use `authority.claims` or provisioner-level claims for certificate lifetimes, renewal behavior, and SSH CA enablement. Avoid `allowRenewalAfterExpiry` unless the task explicitly accepts the added risk for intermittently connected clients.
+- Add `authority.policy` when constraining which X.509 SANs or SSH principals Janus may issue. This is mandatory for any move away from private/LAN-only operation.
+
+## CA Material And Secret Placement
+
+Store each kind of material in the narrowest place that matches who needs it:
+
+- `modules/hosts/janus/secrets.yaml`: Janus runtime CA secrets used by `step-ca`, including `janus/ca_password`, `janus/intermediate_ca_key`, `janus/ssh_host_ca_key`, `janus/ssh_user_ca_key`, and `janus/admin_provisioner_encrypted_key`.
+- `keys/secrets.yaml`: shared provisioner credential `janus/admin_jwk`, because client and host certificate modules outside Janus consume it to request certs.
+- `modules/hosts/janus/root_ca.crt`, `intermediate_ca.crt`, `fingerprint`, `ssh_user_ca_key.pub`, and `ssh_host_ca_key.pub`: public trust artifacts that may be committed and reviewed.
+- Offline secret storage only: `root_ca_key` and the root key password. The running CA should not need the root private key for normal operation.
+
+When editing secrets:
+
+- Use SOPS commands (`sops`, `edit-secrets`, or `sops set`) rather than editing `ENC[...]` payloads.
+- Use YAML literal blocks for PEM or OpenSSH private keys so newlines are preserved.
+- After changing Janus recipient rules, run `sops --config .sops.yaml updatekeys -y modules/hosts/janus/secrets.yaml` so the host-local file is actually rewrapped.
+- Keep `.sops.yaml` scoped: Janus host runtime secrets should match `modules/hosts/janus/secrets.yaml`; shared credentials should match `keys/secrets.yaml`.
+
+## Public Trust Artifacts
+
+- If `root_ca.crt` changes, update `fingerprint` from `step certificate fingerprint <root_ca.crt>` and update `modules/features/step-client.nix` defaults in the same change.
+- If `intermediate_ca.crt` changes, confirm it still chains to the committed root and that the running CA uses the matching `intermediate_ca_key` from SOPS.
+- If SSH CA keys rotate, update the matching public key files and every SSH trust consumer, including `modules/services/ssh.nix` known-host CA values and `TrustedUserCAKeys` behavior.
+- Treat `README.md` bootstrap commands as part of the operational contract. Keep them aligned with secret names, public artifact paths, CA URL, DNS names, and IP SANs.
+
+## mTLS And Client Trust
+
+- Janus mTLS values should stay aligned with Step CA identity: update `step-ca.dnsNames`, `mtls.subject`, `mtls.san`, and Step client defaults together when CA names or addresses change.
+- `modules/features/step-client.nix` is the shared bootstrap surface. Its default CA URL, root certificate, and fingerprint should describe Janus unless the repo intentionally migrates to another CA.
+- mTLS certificate files are runtime outputs under the configured cert directory, not tracked source files. Do not store mTLS private keys in Git or the Nix store.
+
+## Step/Nix Troubleshooting Checklist
+
+Start with the smallest check that matches the change:
+
+1. Host evaluation: `nix eval .#nixosConfigurations.janus.config.system.build.toplevel.drvPath`
+2. Build planning: `nix build .#nixosConfigurations.janus.config.system.build.toplevel --no-link --dry-run`
+3. Secret contract: confirm every `step-ca.secrets.*` value has a matching `sops.secrets` declaration and a matching key in `modules/hosts/janus/secrets.yaml`.
+4. Rendered config: on the host, inspect `/etc/smallstep/ca.json` or `/etc/step-ca` paths without copying secret content into logs.
+5. Service health: check `systemctl status step-ca.service`, `journalctl -u step-ca.service`, and `step ca health --ca-url https://janus.john-stream.com` after trust is bootstrapped.
+6. Provisioners: use `step ca provisioner list` to confirm ACME, SSHPOP, and admin JWK availability.
+7. SSH cert flow: use `ssh-host-cert-check`, `systemctl status ssh-certs-renew.service`, and `systemctl status ssh-certs-renew.timer`.
+8. mTLS flow: use `mtls-check`, `mtls-generate`, and `systemctl status mtls-renew.timer` for host certificate renewal issues.
+
+## Change Safety Rules
+
+- Do not deploy a root private key to Janus unless the task explicitly changes the trust model.
+- Do not rename `janus/admin_jwk` without updating all consumers in the same change.
+- Do not expose ACME or `/provisioners` endpoints publicly without an explicit migration away from the private/LAN-only model plus policy and endpoint exposure review.
+- Do not use certificate templates casually; if templates are added, keep them narrow and use `toJson` for user-controlled values.
+- If changing certificate durations, prefer short-lived leaf certs with automated renewal over long-lived leaf certs.
+- If changing service ports or proxying, account for Step renewal behavior: mTLS renewal is sensitive to layer-7 proxies unless configured for token-based renewal.

+# Shared Modules
+
+Files outside `modules/hosts` generally define reusable building blocks, not concrete machines. In this repo, those files usually export one of these surfaces:
+
+- `flake.modules.nixos.<name>` for reusable NixOS modules.
+- `flake.modules.homeManager.<name>` for reusable Home Manager modules.
+- `config.flake.factory.user` for factories that generate per-user module sets.
+- `flake.meta.*` when the file owns reusable metadata that other modules consume.
+
+Keep the boundary between shared modules and hosts clear:
+
+- Shared modules should not define `flake.nixosConfigurations.<name>` or `flake.homeConfigurations.<name>`; those belong in `modules/hosts`.
+- Prefer generic options, imports, and composition over host-specific literals.
+- If a setting only makes sense for one machine, keep it in that host directory instead of moving it into a shared module.
+- When a host imports a shared module, treat the shared module as part of the stable interface that multiple hosts may depend on.
+
+Follow the existing export patterns in this repo:
+
+- Simple reusable modules may export a single module directly, such as `flake.modules.nixos.games`.
+- Cross-cutting features often live under `modules/features` even when they export `flake.modules.nixos.*` or `flake.modules.homeManager.*`.
+- Program and service integrations commonly export one or both module types from a single file.
+- User definitions under `modules/users` may export metadata plus paired NixOS and Home Manager modules for the same user.
+
+For user modules specifically:
+
+- Keep reusable user facts under `flake.meta.users.<name>` when other modules need to reference them.
+- Prefer deriving the NixOS side from `self.factory.user` when the file already follows that pattern.
+- Keep the user-facing Home Manager module in `flake.modules.homeManager.<name>` and let the factory or host wire it into a concrete configuration.
+- Put user-specific authorized keys, identity, and shared defaults here rather than duplicating them across hosts.
+
+Design shared modules as composable interfaces:
+
+- Import other shared modules instead of copying option blocks.
+- Add options or parameters when behavior needs to vary between hosts.
+- Avoid embedding host-specific paths, hostnames, addresses, or secret file locations unless the file is intentionally host-local.
+- Preserve exported attribute names even when the filename is different. In this repo, the path is not always the public API name.
+
+Use nearby files as examples:
+
+- `modules/nixos/games.nix` is a minimal shared NixOS module with no host wiring.
+- `modules/features/nixos-base.nix` defines a reusable base system module that other hosts import.
+- `modules/users/john.nix` combines `flake.meta.users.john`, a reusable NixOS user module, and a reusable Home Manager user module built around the user factory.
+- `modules/nix-tools/user.nix` defines the `flake.factory.user` helper that shared user modules build on.
+
+For reviews and answers, separate these concerns clearly:
+
+- reusable module API and option design in shared module directories
+- concrete host assembly in `modules/hosts`
+- whether a change increases reuse or accidentally pulls machine-specific behavior into a shared layer

+
+# Using SOPS In This Repo
+
+This repo treats SOPS files as the source of encrypted runtime material, and Nix code as the wiring that exposes those secrets to services. Keep those roles separate: edit secret values with SOPS, consume them through sops-nix paths, and keep recipient policy scoped to the machines or operators that actually need access.
+
+## Mental Model
+
+- Secrets live in encrypted YAML files; Nix modules should refer to secret paths, not decrypted values.
+- Host-only credentials belong in `modules/hosts/<host>/secrets.yaml`.
+- Shared credentials belong in `keys/secrets.yaml` only when multiple hosts intentionally consume the same material.
+- `.sops.yaml` controls who can decrypt each file; keep those recipient sets narrow and explicit.
+- Secret key names are an interface. Rename them only when every consumer changes in the same edit.
+
+## Editing Secrets
+
+- Use SOPS tooling for all value changes: `sops <file>`, `edit-secrets`, or `sops set ...`.
+- Do not hand-edit `ENC[...]` payloads. That bypasses SOPS and breaks the encrypted document's integrity metadata.
+- Keep plaintext out of tracked files. Temporary plaintext files are acceptable only as local working inputs and should be removed after use.
+- Prefer `SOPS_EDITOR=nvim sops <file>` for interactive edits when editor choice matters.
+
+For large or generated values, avoid putting the secret directly in shell history:
+
+```bash
+sops set --value-file <secrets-file> '["parent"]["key"]' /path/to/plaintext-value
+```
+
+If using inline `sops set`, the value argument must be valid JSON.
+
+## Multiline Values
+
+Use YAML literal blocks for private keys, certificates, provisioner keys, and other values where newlines matter:
+
+```yaml
+janus:
+  ssh_user_ca_key: |-
+    -----BEGIN OPENSSH PRIVATE KEY-----
+    ...
+    -----END OPENSSH PRIVATE KEY-----
+```
+
+- Use `|-` when the final trailing newline should be stripped.
+- Use `|` when the consuming program expects the final trailing newline.
+- Avoid folded style (`>`) for keys and certs because it rewrites line breaks.
+
+## Wiring Secrets Into Nix
+
+- Consume secrets through `config.sops.secrets."<key>".path` or `config.sops.placeholder` where templating requires it.
+- Do not read decrypted secret contents during Nix evaluation.
+- Set `owner`, `group`, and `mode` explicitly for non-root services.
+- Use `path` or `sops.templates` when a service needs a specific file layout instead of copying secret contents into the store or tracked files.
+- If moving a secret between shared and host-local files, update `sops.defaultSopsFile`, `mysops.hostSecretFile`, and every affected `sops.secrets` declaration together.
+
+## Recipient And Rotation Practices
+
+- Add dedicated `.sops.yaml` `path_regex` rules for host-local files before broad fallback rules.
+- Keep broad fallback rules conservative; do not expand them to grant casual access to every YAML or JSON file.
+- Run `sops updatekeys <file>` after changing recipients so data is rewrapped for the new key set.
+- Rotate or migrate in order: update recipients, re-encrypt affected files, update consumers, then validate affected hosts.
+
+## Validation Habits
+
+After SOPS or sops-nix changes, check the contract rather than only the syntax:
+
+1. The expected secrets file is still selected by `sops.defaultSopsFile` or `mysops.hostSecretFile`.
+2. `.sops.yaml` has a specific rule for any host-local `secrets.yaml` touched.
+3. Secret names in YAML still match the `sops.secrets."<key>"` declarations.
+4. Services that need restart or reload behavior have `restartUnits` or `reloadUnits` set.
+5. Affected host evaluation/build catches missing secret keys before deployment.

+# Soteria Host Instructions
+
+Use this instruction when changing Soteria host wiring in `modules/hosts/soteria`.
+
+## Host Intent And Shape
+
+- Treat Soteria as a NixOS service node for Forgejo, RESTic server, mTLS, and a paired Home Manager profile for `john`.
+- Keep host identity aligned: `hostname = "soteria"`, `networking.hostName = hostname`, and `flake.nixosConfigurations."${hostname}"`.
+- Keep host-local secrets in `modules/hosts/soteria/secrets.yaml` and wire with `sops.defaultSopsFile = ./secrets.yaml`.
+- Keep host-specific Home Manager wiring in `flake.modules.homeManager.soteria`, and keep `mysops.hostSecretFile` pointing at the Soteria secrets file.
+
+## Required Module Composition
+
+When editing `modules/hosts/soteria/default.nix`, preserve this composition unless the task explicitly changes architecture:
+
+- Import `nixos.ssh-certs` to enable host SSH cert integration.
+- Import `nixos.janus-ca` so Step client trust material and defaults remain available.
+- Import `nixos.restic-server` so the RESTic REST server implementation lives in the shared module rather than inline host wiring.
+- Keep `ssh-certs.hostname = hostname;` so cert principals match host naming.
+
+## SSH Cert Mechanics On Soteria
+
+Soteria SSH certificate behavior is the result of multiple modules. Keep this flow intact:
+
+1. `soteria/default.nix` imports `nixos.ssh-certs` and sets `ssh-certs.hostname = "soteria"` (via `hostname`).
+2. `modules/services/step-ca/ssh-host.nix`:
+   - Enables `ssh.certificates.enable = true`.
+   - Requires `sops.secrets."janus/admin_jwk"` (provisioner credential) from Soteria's `secrets.yaml`.
+   - Defines cert paths at `/etc/ssh/ssh_host_ed25519_key` and `/etc/ssh/ssh_host_ed25519_key-cert.pub`.
+   - Exposes `ssh-host-cert-renew` and `ssh-host-cert-check` helper binaries.
+   - Schedules `ssh-certs-renew.timer` every 4h with jitter.
+3. `modules/services/ssh.nix` consumes `ssh.certificates.enable` and configures OpenSSH to:
+   - Set `TrustedUserCAKeys = /etc/ssh/ssh_user_ca_key.pub`.
+   - Set `HostCertificate = /etc/ssh/ssh_host_ed25519_key-cert.pub`.
+   - Install the trusted user CA file into `/etc/ssh/ssh_user_ca_key.pub`.
+4. `nixos.janus-ca` provides Step CA trust bootstrapping (`/etc/step-ca/defaults.json` and linked root CA material), allowing Step CLI operations to trust and reach the CA endpoint.
+
+Current implementation note:
+
+- `ssh-certs-renew.service` currently checks renewal state via `step ssh needs-renewal` and logs status. It does not directly invoke `ssh-host-cert-renew` in the service script. Preserve this behavior unless the task explicitly asks to change renewal execution semantics.
+
+## SOPS/Secrets Mechanics On Soteria
+
+Soteria secret handling spans host-local secrets, NixOS secret materialization, and Home Manager secret tooling. Keep this flow intact:
+
+1. `modules/hosts/soteria/default.nix` imports `nixos.mysops` and sets `sops.defaultSopsFile = ./secrets.yaml`.
+2. The SOPS file `modules/hosts/soteria/secrets.yaml` is the canonical encrypted source for this host's system secrets.
+3. Shared modules imported by Soteria declare required secret entries under `sops.secrets` and consume them through `config.sops.secrets.<name>.path`:
+   - `modules/services/step-ca/ssh-host.nix` declares and consumes `janus/admin_jwk` as the Step provisioner password file.
+   - `modules/features/forgejo.nix` declares and consumes `forgejo/secret_key`, `forgejo/internal_token`, `forgejo/jwt_secret`, and `forgejo/lfs_jwt_secret`.
+4. Secret ownership is module-defined and must stay aligned with service users:
+   - Forgejo secrets are owned by `config.services.forgejo.user`.
+   - Step SSH provisioner secret is locked to root ownership and `0400` mode.
+5. `flake.modules.homeManager.soteria` imports `homeManager.mysops` and sets `mysops.hostSecretFile` to the same Soteria host secret file path. This drives helper tooling such as `edit-secrets` while Home Manager keeps its own default SOPS context from `modules/programs/sops.nix`.
+
+Current implementation note:
+
+- `restic_password` exists in `modules/hosts/soteria/secrets.yaml`, but it is not currently consumed by the Soteria NixOS module graph.
+- Changing, deleting, or renaming seemingly unused keys in `secrets.yaml` should be treated as a compatibility change and confirmed by the task.
+
+## Restic REST Server On Soteria
+
+Soteria's RESTic REST server is implemented by the shared `nixos.restic-server` module and configured by host-local `resticServer` values. Trace it this way:
+
+1. `modules/hosts/soteria/default.nix` imports `nixos.restic-server` and configures the host-local `resticServer` option set with:
+   - `enable = true`
+   - `dataDir = "/mnt/restic"`
+   - `privateRepos = true`
+   - `listenAddress = "0.0.0.0:8000"`
+   - `tls.certFile = config.mtls.certFile`
+   - `tls.keyFile = config.mtls.keyFile`
+2. `modules/features/restic.nix` maps those `resticServer` options into `services.restic.server` and appends TLS flags when both TLS paths are set.
+3. The shared module keeps the server base behavior in one place:
+   - `services.restic.server.enable = true`
+   - `services.restic.server.dataDir = cfg.dataDir`
+   - `services.restic.server.listenAddress = cfg.listenAddress`
+   - `services.restic.server.privateRepos = cfg.privateRepos`
+   - `services.restic.server.extraFlags = cfg.extraFlags ++ tlsFlags`
+4. `modules/features/restic.nix` also opens the matching TCP port through `networking.firewall.allowedTCPPorts`, deriving it from `resticServer.listenAddress`.
+5. The mTLS renewal hook includes `restic-rest-server.service` in `mtls.renew.reloadUnits`, so certificate rotation reloads the REST server alongside Forgejo.
+6. `loginText.extraServiceStatus` exposes the running unit as `restic-rest-server.service`, which is the service name to keep in mind for status and reload behavior.
+
+### Storage Location
+
+- Soteria explicitly sets `resticServer.dataDir = "/mnt/restic"`.
+- The shared module maps that value into `services.restic.server.dataDir`, so `/mnt/restic` is now the intended repository storage location for this host.
+- The shared module also derives the firewall port from `resticServer.listenAddress`, so Soteria no longer needs a separate `networking.firewall.allowedTCPPorts = [ 8000 ]` line.
+- If storage needs to move later, change the `resticServer.dataDir` input or the shared module contract, not ad hoc service cleanup logic.
+- `privateRepos = true` constrains repo exposure behavior, but it does not define storage location by itself.
+
+Current implementation note:
+
+- The REST server is TLS-protected but currently passed `--no-auth`, so client access control relies on transport/security model rather than rest-server password auth.
+- The shared module default listen address is not Soteria's deployed value; Soteria deliberately overrides it to `0.0.0.0:8000` in the host.
+
+## Forgejo Implementation On Soteria
+
+Soteria's Forgejo setup is split between host-local option values and the shared `nixos.forgejo` module. Trace it this way:
+
+1. `modules/hosts/soteria/default.nix` imports `nixos.forgejo` and enables it with:
+   - `forgejo.enable = true`
+   - `forgejo.root_url = "https://forgejo.john-stream.com"`
+   - `forgejo.https = true`
+   - `forgejo.port = 443`
+2. `modules/features/forgejo.nix` defines `forgejo.port` as the controlling option for the web listener. Its default is `3000`, but Soteria overrides it to `443`.
+3. The shared module wires that option into multiple places:
+   - `services.forgejo.settings.server.HTTP_PORT = cfg.port`
+   - `networking.firewall.allowedTCPPorts = [ cfg.port ]` when `openFirewall = true`
+   - If `cfg.port < 1024`, the Forgejo systemd unit gets `CAP_NET_BIND_SERVICE` so it can bind a privileged port.
+4. HTTPS on Soteria is terminated directly by Forgejo using mTLS-managed files:
+   - `services.forgejo.settings.server.PROTOCOL = "https"`
+   - `KEY_FILE = config.mtls.keyFile`
+   - `CERT_FILE = config.mtls.certFile`
+
+### Storage Locations
+
+- This repo does not override Forgejo's primary state directory in the Soteria host or in `modules/features/forgejo.nix`.
+- That means Forgejo storage follows the underlying NixOS `services.forgejo` defaults, exposed in this config as `config.services.forgejo.stateDir`.
+- PostgreSQL storage is also left at the underlying module default and is referenced as `config.services.postgresql.dataDir`.
+- The cleanup helpers in `modules/features/forgejo.nix` confirm these are the intended storage anchors because they remove exactly `config.services.forgejo.stateDir` and `config.services.postgresql.dataDir`.
+- Forgejo backup dumps are generated by `forgejo-dump.service` using `--work-path ${config.services.forgejo.dump.backupDir}`, so dump staging/output follows the Forgejo module's backup directory setting rather than a Soteria-specific path override.
+
+Current implementation note:
+
+- If you need to change Forgejo storage location on Soteria, do it by setting the underlying Forgejo or PostgreSQL service directory options explicitly, not by changing cleanup scripts alone.
+- If you need to change the external Forgejo endpoint, update `forgejo.root_url`, `forgejo.port`, and the Soteria mTLS SAN list together.
+
+## Change Safety Rules
+
+- Do not rename the secret key `janus/admin_jwk` without updating all consumers.
+- Do not change SSH host key/cert filenames unless OpenSSH `HostKey`/`HostCertificate` paths are updated together.
+- If changing hostnames or domains, update cert principals in `ssh-certs` and corresponding SSH client targets together.
+- If adding or removing `nixos.ssh-certs`, explain impact on SSH cert issuance, renewal, and trust in the change summary.

+# Step SSH Host Module Instructions
+
+Use this instruction when changing the shared NixOS module in modules/services/step-ca/ssh-host.nix.
+
+## Module Contract
+
+- Keep this module reusable across hosts; do not hard-code host-local file paths beyond SSH system paths under /etc/ssh.
+- Preserve the option interface unless the task explicitly changes it:
+  - ssh-certs.hostname (required host identity used for cert principals)
+  - ssh-certs.provisioner (default: "admin")
+- Keep imports = [ inputs.self.modules.nixos.ssh ] so OpenSSH host certificate settings stay composed through the shared SSH module.
+
+## Secret Key Contract
+
+- This module currently consumes `config.sops.secrets."janus/admin_jwk"` as the Step provisioner password file.
+- Treat `janus/admin_jwk` as a public contract key name for current consumers. If you rename it, update all consumers and host secret files in the same change.
+- Keep secret permissions strict (root ownership and 0400 mode).
+- Do not assume a local sops file path in this module. The consuming host must define sops.defaultSopsFile.
+
+## Host Expectations
+
+When this module is enabled by a host, the host is expected to provide:
+
+- A working Step trust/bootstrap path (for example via janus-ca or equivalent trust material).
+- `sops.defaultSopsFile` containing `janus.admin_jwk` (or equivalent if contract is intentionally changed everywhere).
+- `ssh-certs.hostname` matching deployed host identity and DNS naming expectations.
+
+## SSH Certificate Paths And Principals
+
+- Preserve the default host key path contract at `/etc/ssh/ssh_host_ed25519_key` unless task scope requires coordinated changes.
+- Keep host certificate path aligned to `${sshKeyPath}-cert.pub`.
+- Keep principal issuance based on hostname and hostname.john-stream.com unless domain policy is intentionally migrated.
+- If changing key/cert filenames or principal naming, update `modules/services/ssh.nix` integration and host rollout notes in the same change.
+
+## Renewal Behavior
+
+- Maintain timer/service cadence unless explicitly requested:
+  - timer OnUnitActiveSec = 4h
+  - randomized delay enabled
+- Keep explicit handling for step ssh needs-renewal return codes to avoid silent failures.
+- If changing renewal semantics, document whether the service now only checks state or also performs certificate issuance.
+
+## Validation Checklist
+
+After editing this module, validate at least one consuming host with:
+
+1. nix eval .#nixosConfigurations.janus.config.system.build.toplevel.drvPath
+2. nix build .#nixosConfigurations.janus.config.system.build.toplevel --no-link --dry-run

+description: "Use when modifying jsl-zsh, home-manager programs.zsh settings, or shell-tools wiring. Explains when to use wrapped jsl-zsh versus pkgs.zsh and how shell-tools composes into user and host configs."
+applyTo: 'modules/programs/zsh.nix, modules/features/shell-tools.nix, modules/users/**/*.nix, modules/nix-tools/user.nix, modules/services/ssh.nix, modules/hosts/**/*.nix'
+---
+
+# jsl-zsh and shell-tools wiring
+
+This repo intentionally uses two zsh variants for different layers:
+
+- `pkgs.zsh` is the base system shell used for user login shell declarations.
+- `inputs.self.packages.<system>.jsl-zsh` is the wrapped interactive shell used by Home Manager and remote shell entrypoints.
+
+Treat these as distinct roles, not interchangeable defaults.
+
+## Canonical definitions
+
+The canonical wrapped shell is defined in `modules/programs/zsh.nix`:
+
+- `perSystem.packages.jsl-zsh` wraps zsh via `wrapperModules.zsh.apply`.
+- Wrapper settings, aliases, history behavior, devenv hook, and extra package PATH come from this package definition.
+- `binName = "jsl-zsh"` is part of the external contract; keep it stable unless performing an explicit repo-wide rename.
+
+The Home Manager zsh module in the same file is the canonical consumer:
+
+- `flake.modules.homeManager.zsh` sets `programs.zsh.package` to `self.packages.<system>.jsl-zsh`.
+- Keep Home Manager interactive zsh bound to the wrapped package, not plain `pkgs.zsh`.
+
+## shell-tools composition
+
+`modules/features/shell-tools.nix` is a composition module, not just a package list:
+
+- `flake.modules.homeManager.shell-tools` imports `homeManager.zsh` and `homeManager.files`.
+- It adds the wrapped `shell-tools` package to `home.packages`.
+- `home.shell.enableShellIntegration = true` is expected to stay with this module.
+
+If a user module imports `homeManager.shell-tools` (for example `modules/users/john.nix`), that user already receives the Home Manager zsh wiring transitively.
+
+## System-layer expectations
+
+`modules/nix-tools/user.nix` keeps system login semantics separate from Home Manager interactive behavior:
+
+- `users.users.<name>.shell = pkgs.zsh` remains the login shell declaration.
+- `programs.zsh.enable = true` enables system zsh support.
+- `environment.shells` includes both `${lib.getExe pkgs.zsh}` and `${lib.getExe self.packages.<system>.jsl-zsh}` so wrapped shell paths are recognized when needed.
+
+Do not replace login shell declarations with `jsl-zsh` unless the task is explicitly changing system login policy.
+
+## Host and SSH usage contracts
+
+Hosts may include `selfPkgs.jsl-zsh` in `environment.systemPackages` or `home.packages` so the wrapped shell is available directly.
+
+`modules/services/ssh.nix` includes host entries that use `RemoteCommand = "~/.nix-profile/bin/jsl-zsh"` (and commented variants). This path-level usage means:
+
+- keep the wrapper executable name stable (`jsl-zsh`),
+- update SSH remote command references in the same change if shell invocation paths are changed.
+
+## Change guidelines
+
+When editing this area:
+
+- Keep wrapper behavior changes in `packages.jsl-zsh` focused and centralized.
+- Keep Home Manager zsh package selection pointed at wrapped `jsl-zsh`.
+- Keep system login shell semantics (`pkgs.zsh`) and interactive wrapper semantics (`jsl-zsh`) separated unless intentionally redesigning both layers.
+- If modifying `shell-tools`, verify it still composes zsh and tool packages for users importing the module.
+- If changing executable names or invocation paths, update all dependent consumers (including SSH remote commands and host package lists) in one coherent change.

+```
+
+Generate the Janus OpenSSH host key for reference (Janus now uses whatever key
+already exists on the target at `/etc/ssh/ssh_host_ed25519_key`):
+
+```shell
+ssh-keygen -t ed25519 -N '' -C janus@john-stream.com -f /tmp/janus-step-ca-bootstrap/ssh_host_ed25519_key
+```
+
+Bootstrap CA materials with SSH enabled:
+```shell
+STEPPATH=/tmp/janus-step-ca-bootstrap/step step ca init --name Janus --dns janus.john-stream.com --dns 192.168.1.244 --address :443 --provisioner admin --password-file /tmp/janus-step-ca-bootstrap/ca_password.txt --provisioner-password-file /tmp/janus-step-ca-bootstrap/admin_jwk_password.txt --ssh --deployment-type standalone --with-ca-url https://janus.john-stream.com
+```
+
+Insert generated runtime CA material into `modules/hosts/janus/secrets.yaml` under `janus`:
+
+- `/tmp/janus-step-ca-bootstrap/ca_password.txt` -> `ca_password`
+- `/tmp/janus-step-ca-bootstrap/step/secrets/intermediate_ca_key` -> `intermediate_ca_key`
+- `/tmp/janus-step-ca-bootstrap/step/secrets/ssh_host_ca_key` -> `ssh_host_ca_key`
+- `/tmp/janus-step-ca-bootstrap/step/secrets/ssh_user_ca_key` -> `ssh_user_ca_key`
+- `/tmp/janus-step-ca-bootstrap/step/config/ca.json` -> `admin_provisioner_encrypted_key` (copy `authority.provisioners[].encryptedKey` for the `admin` JWK provisioner)
+
+If you are only validating wiring first, `admin_provisioner_encrypted_key` can be an encrypted placeholder and replaced later.
+
+If rotating provisioner password, also set:
+
+- `/tmp/janus-step-ca-bootstrap/admin_jwk_password.txt` -> `janus.admin_jwk` in `keys/secrets.yaml`
+
+Secret source-of-truth after this split:
+
+- `modules/hosts/janus/secrets.yaml`: Janus runtime CA secrets (`ca_password`, `intermediate_ca_key`, `ssh_host_ca_key`, `ssh_user_ca_key`, `admin_provisioner_encrypted_key`)
+- `keys/secrets.yaml`: shared Janus provisioner secret (`janus.admin_jwk`) consumed by `ssh-certs` across hosts
+
+Then update public artifacts in repo from generated output:
+
+- `modules/hosts/janus/root_ca.crt` from `/tmp/janus-step-ca-bootstrap/step/certs/root_ca.crt`
+- `modules/hosts/janus/intermediate_ca.crt` from `/tmp/janus-step-ca-bootstrap/step/certs/intermediate_ca.crt` (public certificate; intentionally committed, not stored in SOPS)
+- `modules/hosts/janus/fingerprint` from:
+	```shell
+	step certificate fingerprint /tmp/janus-step-ca-bootstrap/step/certs/root_ca.crt
+	```
+- `modules/hosts/janus/ssh_user_ca_key.pub` from `/tmp/janus-step-ca-bootstrap/step/certs/ssh_user_ca_key.pub`
+- `modules/hosts/janus/ssh_host_ca_key.pub` from `/tmp/janus-step-ca-bootstrap/step/certs/ssh_host_ca_key.pub`
+
+## First boot checks
+
+After switching Janus, verify the declarative bootstrap units instead of running
+ad hoc issuance commands first:
+
+```shell
+systemctl status step-ca.service
+systemctl status ssh-certs-renew.service
+systemctl status ssh-certs-renew.timer
+systemctl status mtls-bootstrap.service
+ssh-host-cert-check
+mtls-check
+```
+
+`ssh-certs-renew.service` issues the SSH host certificate when it is missing
+or expiring. `mtls-bootstrap.service` issues the first Janus mTLS bundle
+only when the configured certificate files are absent or invalid; recurring mTLS
+renewal remains handled by `mtls-renew.timer`.
+
+## Back up the root CA key offline
+
+The root CA private key is **not** deployed and is never needed by the running CA.
+It is only used to sign/rotate intermediates. Store it offline (e.g. 1Password)
+before wiping the bootstrap directory, otherwise intermediate rotation becomes
+impossible and any future rotation forces a full root rotation (redistributing
+`root_ca.crt` + `fingerprint` to every client).
+
+Back up, then wipe the bootstrap material:
+
+- `/tmp/janus-step-ca-bootstrap/step/secrets/root_ca_key` -> offline secret store
+- `/tmp/janus-step-ca-bootstrap/ca_password.txt` -> offline secret store (root/intermediate key password)
+
+```shell
+shred -u /tmp/janus-step-ca-bootstrap/step/secrets/root_ca_key 2>/dev/null || true
+rm -rf /tmp/janus-step-ca-bootstrap
+```
