+# Repository Guidelines
+
+## Project Structure & Module Organization
+This repository is a Den-based NixOS flake. `flake.nix` evaluates `./modules` through `import-tree`, so normal `.nix` files under `modules/` are auto-imported.
+
+- `modules/hosts/` contains host-specific composition and hardware data for `polaris` and `orion`.
+- `modules/features/` contains aspects such as desktop, shell, services, and Neovim.
+- `modules/profiles/` holds higher-level bundles such as `workstation.nix`.
+- `modules/users/` defines user metadata and per-user behavior.
+- `modules/secrets/` wires `sops-nix` and stores the encrypted `secrets.yaml`.
+- `.agents/den/` is a local checkout of Den with source, docs, and examples.
+
+Keep host files thin. Shared behavior belongs in `modules/features/` or `modules/profiles/`.
+When Den behavior is unclear, read `.agents/den/docs/`, `.agents/den/modules/`, and `.agents/den/templates/ci/` before guessing.
+
+## Build, Test, and Development Commands
+Run commands from the repository root.
+
+- `nix build .#nixosConfigurations.polaris.config.system.build.toplevel --show-trace`: evaluate and build the Polaris system.
+- `nix build .#nixosConfigurations.orion.config.system.build.toplevel --show-trace`: evaluate and build the Orion system.
+- `nixos-rebuild build --flake .#<host>`: use the standard rebuild path without activating it.
+- `nix fmt`: format Nix files using the flake-provided formatter.
+- `nix eval .#nixosConfigurations.<host>.config.<option>`: inspect a single option while iterating.
+
+`nix flake check` is useful for evaluation, but this repo does not define an automated test suite.
+
+## Coding Style & Naming Conventions
+Use two-space indentation and standard Nix attrset formatting. Prefer small `let` bindings, lowerCamelCase local names, and lowercase file names such as `sops-password.nix`. Match the surrounding module style instead of reformatting unrelated code.
+
+Prefer Den composition through `includes`; avoid host-specific duplication when a reusable aspect is clearer.
+
+## Testing Guidelines
+There are no first-party unit tests. Treat evaluation and build-only checks as the baseline. For scoped changes, run the matching `nix build` target first, or `nixos-rebuild build --flake .#<host>` when you want the standard rebuild path without activation. Activation and switching are manual steps and should not be performed by contributors or agents.
+
+## Commit
+Follow the history style: short imperative subjects, optionally with a conventional prefix, for example `refactor: restructure openssh config`. Keep each commit focused on one concern.
+
+## Security & Configuration Tips
+Never commit plaintext secrets. Add or update secrets through `modules/secrets/secrets.yaml` and reference them via `config.sops.secrets.<name>.path`. Be explicit about firewall, SSH, disk, or boot changes; those are the highest-risk edits here.

+# Notes
+## 16-04
+- See if pinentry should be a variable and how pure ssh (no gpg anymore) handles pinentry.
+- Reconsider placement and existence of system-base.nix
+- Implement system-wide theming system
+- Do we need separate stateVersions per host?
+- pinentry.nix should not set programs consuming it explicitly, should probably be host-level concern or smoething.
+- Primary email schema validation should not be located inside aspects like git.nix but somewhere in the schema definition probably
+- assertions are defined, not sure if that actually does anything.
+
+Code style related todos:
+Consistent rules/guidelines for function or attribute set at root of aspect file.
+When to nest sets and when to set directly (podman.nix).

+# Session Log
+
+## Current Repo State
+- The git worktree is dirty. Many files were already modified before or during this session. Do not revert unrelated changes.
+- New main host/user additions are already in place:
+  - hosts: `polaris`, `zenith`, `orion`
+  - users: `kiri`, `ergon`
+- `zenith` is the Lenovo Yoga Slim 7 ProX 14ARH7 laptop.
+- `ergon` is the work user and is present on `polaris` and `zenith`, not `orion`.
+
+## Naming Decisions
+- Host names chosen:
+  - `polaris` = main machine
+  - `zenith` = laptop
+  - `orion` = VPS
+- Work user chosen:
+  - `ergon`
+
+## Den / Architecture Decisions
+- `kiri` stays on `den._.primary-user`.
+- `ergon` is explicit and should not use `den._.primary-user`.
+- Do not introduce a local `admin-user` battery yet. Keep repeated patterns explicit until they stabilize.
+- Prefer host files thin and move reusable behavior into `modules/features/` or `modules/profiles/`.
+
+## Den Helper Mental Model
+- `perHost` / `perUser` are stage gates, not just readability helpers.
+- `perUser` is not the same as `parametric.exactly`.
+- Actual behavior:
+  - `perUser` gates entry at exact `{ host, user }`, then evaluates the wrapped aspect under fixed `{ host, user }` with normal `atLeast` matching inside.
+  - `parametric.exactly` is an inner include matcher based on exact context shape.
+- Practical rule used in this repo:
+  - use `perHost` for host-owned NixOS config that must apply once per host
+  - use `perUser` for host-user-pair HM or NixOS config
+  - avoid `take.*` unless doing low-level Den plumbing
+
+## Niri / Display Model
+- `lux.niri` was intentionally collapsed back into one conceptual aspect in `modules/features/niri.nix`.
+- It now uses:
+  - `den.lib.perHost` for NixOS-side Niri setup
+  - `den.lib.perUser` for HM-side Niri settings
+- Host monitor layout is a host fact, not a user fact.
+- `den.schema.host.displays` exists and is the source of truth for monitor facts.
+- Current `polaris` display layout lives in `modules/infra.nix`.
+- `programs.niri.settings.outputs` is derived from `host.displays`, so both `kiri` and `ergon` on `polaris` get the same output configuration.
+- `displays` intentionally has no `enabled` flag; omission means absent.
+
+## SOPS / SSH / GPG Decisions
+- Repo-managed GPG was removed from `modules/features/ssh.nix`.
+- If commit signing is added later, prefer SSH signing rather than restoring repo-managed GPG.
+- Secret recipient policy currently is:
+  - one admin age recipient
+  - `orion` SSH host key recipient
+- `.sops.yaml` and `modules/secrets/secrets.yaml` were rekeyed to that policy.
+
+## Current SOPS Model
+- SOPS is now host-owned conceptually.
+- Current host schema fields:
+  - `sopsHostSshKeyPath`
+  - `sopsAdminKeyPath`
+  - `sopsAdminKeyUsers`
+- Current policy:
+  - `orion` uses `sops.age.sshKeyPaths = [ "/etc/ssh/ssh_host_ed25519_key" ]` for host-level NixOS decryption.
+  - local hosts (`polaris`, `zenith`) use `/var/lib/sops-nix/admin-key.txt` for host-level NixOS decryption.
+  - HM SOPS also uses the host-provisioned `/var/lib/sops-nix/admin-key.txt`, but only for users listed in `host.sopsAdminKeyUsers`.
+- Shared reader group:
+  - `sops-users`
+- Current host metadata in `modules/infra.nix`:
+  - `polaris.sopsAdminKeyPath = "/var/lib/sops-nix/admin-key.txt"`
+  - `polaris.sopsAdminKeyUsers = [ "kiri" "ergon" ]`
+  - `zenith.sopsAdminKeyPath = "/var/lib/sops-nix/admin-key.txt"`
+  - `zenith.sopsAdminKeyUsers = [ "kiri" "ergon" ]`
+  - `orion.sopsAdminKeyPath = "/var/lib/sops-nix/admin-key.txt"`
+  - `orion.sopsAdminKeyUsers = [ "kiri" ]`
+  - `orion.sopsHostSshKeyPath = "/etc/ssh/ssh_host_ed25519_key"`
+- Important operational caveat:
+  - the admin key file is expected to be provisioned out-of-band on hosts
+  - config creates `/var/lib/sops-nix` via tmpfiles and adds listed users to `sops-users`, but does not create the private key itself
+
+## SSH Recovery Policy
+- `orion` is treated as the remote recovery-critical host.
+- `modules/features/services/openssh.nix` now owns both:
+  - OpenSSH base config
+  - user `authorizedKeys`
+- Recovery assertions now enforce for `requiresSshRecovery = true`:
+  - OpenSSH enabled
+  - password auth disabled
+  - root login disabled
+  - `sshRecoveryUsers` non-empty
+  - every recovery user exists
+  - every recovery user has plain `authorizedSshKeys`
+  - `sopsHostSshKeyPath` non-null
+  - SSH exposed through firewall
+- `AllowUsers = lib.attrNames host.users` is still the intended model.
+
+## Recent Validation Results
+- Successfully built after the Niri / SOPS / SSH refactors:
+  - `nix build .#nixosConfigurations.polaris.config.system.build.toplevel --show-trace`
+  - `nix build .#nixosConfigurations.orion.config.system.build.toplevel --show-trace`
+  - `nix build .#nixosConfigurations.zenith.config.system.build.toplevel --show-trace`
+- Verified by evaluation:
+  - `polaris` Niri outputs for `kiri` and `ergon` match
+  - local hosts resolve `config.sops.age.keyFile = "/var/lib/sops-nix/admin-key.txt"`
+  - `orion` resolves `config.sops.age.sshKeyPaths = [ "/etc/ssh/ssh_host_ed25519_key" ]`
+  - HM SOPS for allowed users resolves `"/var/lib/sops-nix/admin-key.txt"`
+  - `ergon@polaris` has `["sops-users", "wheel", "networkmanager"]`
+  - tmpfiles includes `d /var/lib/sops-nix 0750 root sops-users -`
+
+## Remaining Warnings / Caveats
+- Builds still emit pre-existing Home Manager default-change warnings:
+  - `gtk.gtk4.theme`
+  - `xdg.userDirs.setSessionVariables`
+  - `programs.git.signing.format`
+- These warnings were not addressed in this session.
+- There is no deployment wrapper or automated bootstrap tooling yet.
+- `nixos-anywhere --copy-host-keys` remains the intended `orion` install approach when preserving the SSH host key for first-boot SOPS decryption.
+
+## Architecture Contract
+- Added `ARCHITECTURE.md` as the single durable reference for the repo's intended 1.0 structure.
+- The contract is grounded in the current codebase:
+  - `schema` and `infra` own facts
+  - `users` own cross-host user baselines
+  - `features` own reusable behavior
+  - `profiles` and `environments` own bundling
+  - `hosts` stay thin and compose the final machine shape
+- Kept the existing Den helper convention explicit:
+  - `perHost` and `perUser` are stage gates
+  - `parametric.exactly` is only for exact inner matching
+  - avoid new local batteries until the pattern is stable
+- No repo redesign was done; this was documentation only.
+- Validation:
+  - doc-only change
+  - no `nix build` run in this session
+- Small open question for later:
+  - whether `ARCHITECTURE.md` should stay standalone or also be linked from `AGENTS.md` / future README if a contributor-facing index is added
+
+## Architecture Simplification
+- Collapsed `environments` into `profiles`.
+- Current rule is now simpler:
+  - `features` are the smallest reusable behavior units
+  - `profiles` are all named bundles larger than a single feature
+  - `hosts` still own final composition and explicit host-specific exceptions
+- `modules/environments.nix` was removed.
+- `graphical` and `development` now live under `lux.profiles._`.
+- Kept the repeated `provides.kiri` / `provides.ergon` host wiring explicit for now. The duplication is intentional until a shared host-composition pattern is clearly stable enough to justify extraction.
+- Validation:
+  - `nix build .#nixosConfigurations.polaris.config.system.build.toplevel --show-trace`
+  - `nix build .#nixosConfigurations.orion.config.system.build.toplevel --show-trace`
+  - `nix build .#nixosConfigurations.zenith.config.system.build.toplevel --show-trace`
+
+## MANUAL INTERVENTION NOTE BY HUMAN USER, NOT AI AGENT
+Removed `ARCHITECTURE.md`. Pinning down the architecture this explicitly feels too rigid and unnecessary.
+Perhaps a more generally applicable Design Philsophy would be more helpful and allow for more flexibility.

+# Tasks
+
+This file is an execution queue for independent Codex sessions.
+
+Rules for every task:
+- Work in `/home/kiri/.config/nixos`.
+- Read `SESSION_LOG.md` first.
+- Preserve current architecture unless the task explicitly asks to refine it.
+- Keep unrelated changes out of scope.
+- Validate your work with the relevant `nix build` commands whenever possible.
+- Do not revert unrelated dirty-worktree changes.
+- Append a short entry to `SESSION_LOG.md` at the end of the task. The entry should record:
+  - important decisions made
+  - short reasoning behind those decisions
+  - important structural code changes
+  - validation results
+  Keep it concise and useful for the next independent session.
+
+## Task 1
+
+```text
+Work in /home/kiri/.config/nixos.
+
+Read AGENTS.md and SESSION_LOG.md first.
+
+Task: remove the remaining Home Manager default-change warnings without changing intended behavior.
+
+Known warnings from the previous session:
+- gtk.gtk4.theme
+- xdg.userDirs.setSessionVariables
+- programs.git.signing.format
+
+Likely files:
+- modules/features/theme.nix
+- modules/features/xdg.nix
+- modules/features/dev.nix
+
+Requirements:
+- Keep changes minimal and explicit.
+- Match surrounding Nix style.
+- Do not restructure unrelated parts of the repo.
+- Validate by building all three hosts:
+  - nix build .#nixosConfigurations.polaris.config.system.build.toplevel --show-trace
+  - nix build .#nixosConfigurations.orion.config.system.build.toplevel --show-trace
+  - nix build .#nixosConfigurations.zenith.config.system.build.toplevel --show-trace
+
+Done when:
+- the known warning set above no longer appears
+- all three builds succeed
+
+Expected output:
+- the code changes
+- the validation results
+- a short explanation of the final choices
+- a short appended entry in SESSION_LOG.md for the next session
+```
+
+## Task 2
+
+```text
+Work in /home/kiri/.config/nixos.
+
+Read AGENTS.md and SESSION_LOG.md first, then inspect the current module structure.
+
+Task: define a short architecture contract for the repo's intended 1.0 state.
+
+The goal is not to redesign the repo. The goal is to document the structure and philosophy that should remain stable after the current cleanup phase.
+
+The document should cover:
+- the layering model of the repo
+- where things should go
+- how to think about hosts vs users vs features vs profiles vs environments
+- the practical mental model for Den helper usage
+- the abstraction bar for introducing new batteries
+- how to add or remove a host, user, or feature cleanly
+
+Requirements:
+- Keep it concise and operational.
+- Ground it in the current codebase, not wishful architecture.
+- Use the existing decisions in SESSION_LOG.md, especially the Den helper mental model.
+- Prefer one clear reference document over scattered notes.
+
+Done when:
+- there is one short durable architecture reference in the repo
+- it reflects the actual current repo structure
+- it is specific enough to guide future changes
+
+Expected output:
+- the new or updated doc
+- a short summary of the principles it establishes
+- any small open questions that should be decided later
+- a short appended entry in SESSION_LOG.md for the next session
+```
+
+## Task 3
+
+```text
+Work in /home/kiri/.config/nixos.
+
+Read AGENTS.md and SESSION_LOG.md first.
+
+Task: audit the service composition and recovery behavior for the orion host, and make the ownership model clearer where needed.
+
+Important context:
+- orion is the remote recovery-critical host
+- modules/features/services/openssh.nix currently owns the base SSH and recovery assertions
+- modules/features/services/gitea.nix also writes services.openssh.settings.AllowUsers
+- the previous session intentionally tightened SSH recovery requirements
+
+Focus on:
+- modules/hosts/orion/default.nix
+- modules/features/services/openssh.nix
+- modules/features/services/caddy.nix
+- modules/features/services/gitea.nix
+- modules/features/services/vaultwarden.nix
+- modules/features/services/actual.nix
+- modules/features/services/radicale.nix
+- any other file directly involved in orion service composition
+
+Requirements:
+- Do not do broad architectural refactors outside this scope.
+- Prefer making ownership explicit over adding clever abstraction.
+- If a cross-module write is acceptable, document why.
+- If it is not acceptable, simplify it.
+- Validate with:
+  - nix build .#nixosConfigurations.orion.config.system.build.toplevel --show-trace
+
+Done when:
+- SSH policy ownership is clear
+- cross-module writes that affect recovery or exposure are removed, consolidated, or explicitly justified
+- orion still builds successfully
+- the final state is easier to explain than the starting state
+
+Expected output:
+- the code changes
+- what was ambiguous before
+- how the final ownership model works
+- validation results
+- a short appended entry in SESSION_LOG.md for the next session
+```
+
+## Task 4
+
+```text
+Work in /home/kiri/.config/nixos.
+
+Read AGENTS.md and SESSION_LOG.md first. Treat the "Den Helper Mental Model" section as the current convention baseline.
+
+Task: do a final structural audit and cleanup pass aimed at preparing the repo for an initial 1.0 state.
+
+This task has four parts:
+1. Validate every aspect/helper usage against the current Den helper conventions.
+2. Fix helper mismatches or explicitly justify them.
+3. Remove dead, stale, empty, or misleading scaffolding where safe.
+4. Scan the repo for patterns that might deserve extraction into reusable batteries, and produce a small decision list: introduce / defer / reject.
+
+The helper validation must review usage of:
+- den.lib.perHost
+- den.lib.perUser
+- den.lib.parametric.exactly
+- den.lib.parametric.atLeast
+- avoid take.* unless truly needed
+
+Important constraints:
+- The goal is repo clarity, not abstraction for its own sake.
+- A battery should only be introduced if it makes the repo simpler and reflects one stable underlying idea.
+- One explicit candidate to evaluate is a possible lux.admin-user battery, but do not assume it should exist.
+- Keep the repo grounded in the conventions already established by the previous session.
+
+Suggested approach:
+- inventory aspect/helper usage first
+- review mismatches and repeated patterns
+- decide what should remain explicit
+- make only the cleanup/refactor changes that are justified by that review
+
+Done when:
+- every aspect/helper use has been reviewed against the stated conventions
+- any mismatches are fixed or explicitly justified
+- the repo is simpler or clearer afterward
+- there is a short decision list for abstraction candidates, including lux.admin-user
+
+Expected output:
+- any code cleanup or helper-fix changes
+- a short audit summary
+- a decision list for abstraction candidates, including lux.admin-user
+- any residual risks or open questions
+- a short appended entry in SESSION_LOG.md for the next session
+```
