 nix run .#apply               # Build and apply locally (darwin-rebuild/nixos-rebuild switch)
 nix flake check               # Validate flake
 ```
 
 ### Remote Deployment (NixOS only)
 ```bash
-nix run .#deploy              # Deploy to all NixOS hosts
+colmena build                 # Build all NixOS hosts

 ### File Structure
-- **Modules**: `modules/` - All configuration (flake-parts modules, auto-imported by import-tree)
+- **Hosts**: `hosts/<hostname>/` - Per-machine configurations
-  - `hosts/` - Per-host composition modules
+  - Darwin: `chidi`, `jason`
-  - `profiles/` - Shared host and user profile bundles
+  - NixOS: `michael`, `tahani`
-  - `_lib/` - Utility functions (underscore = ignored by import-tree)
+- **Profiles**: `profiles/` - Reusable program/service configurations (imported by hosts)
-  - `_darwin/` - Darwin-specific sub-modules
+- **Modules**: `modules/` - Custom NixOS/darwin modules
-  - `_neovim/` - Neovim plugin configs
+- **Lib**: `lib/` - Shared constants and utilities
-  - `hosts/_parts/` - Host-specific leaf files (disk-config, hardware, service fragments, etc.)
-- **Apps**: `apps/` - Per-system app scripts (Nushell)
 - **Secrets**: `secrets/` - SOPS-encrypted secrets (`.sops.yaml` for config)
 
-### Architecture
-
-**Framework**: den (vic/den) — every .nix file in `modules/` is a flake-parts module
-
-**Pattern**: Feature/aspect-centric, not host-centric
-
-**Aspects**: `den.aspects.<name>.<class>` where class is:
-- `nixos` - NixOS-only configuration
-- `darwin` - macOS-only configuration
-- `homeManager` - Home Manager configuration
-- `os` - Applies to both NixOS and darwin
-
-**Hosts**: `den.hosts.<system>.<name>` declared in `modules/inventory.nix`
-
-**Profiles**: shared bundles live under `modules/profiles/{host,user}` and are exposed as `den.aspects.host-*` and `den.aspects.user-*`
-
-**Defaults**: `den.default.*` defined in `modules/defaults.nix`
-
-**Imports**: Auto-imported by import-tree; underscore-prefixed dirs (`_lib/`, `_darwin/`, etc.) are excluded from auto-import
-
-**Deployment**: deploy-rs for NixOS hosts (michael, tahani); darwin hosts (chidi, janet) are local-only
-

 ### Naming Conventions
-- **Aspect names**: `den.aspects.<name>.<class>` for feature configuration
+- **Option names**: `my.<feature>.<option>` for custom modules
-- **Hostnames**: Lowercase, descriptive (e.g., `michael`, `tahani`, `chidi`, `janet`)
+- **Hostnames**: Lowercase, descriptive (e.g., `michael`, `tahani`)
-- **Module files**: Descriptive, lowercase with hyphens (e.g., `neovim-config.nix`)
+- **Profile files**: Descriptive, lowercase with hyphens (e.g., `homebrew.nix`)
 
 ### Secrets Management
 - Use SOPS for secrets (see `.sops.yaml`)
 - Never commit unencrypted secrets
-- Secret definitions live in per-host modules (`modules/hosts/michael.nix`, `modules/hosts/tahani.nix`, etc.)
+- Secrets files in `hosts/<host>/secrets.nix` import SOPS-generated files
-- Shared SOPS defaults (module imports, key paths) in `modules/secrets.nix`
 
-### Aspect Composition
+### Imports Pattern
-Use `den.aspects.<name>.includes` to compose aspects:
+Host configs import:
-```nix
+1. System modules (`modulesPath + "/..."`)
-den.aspects.myfeature.includes = [
+2. Host-specific files (`./disk-config.nix`, `./hardware-configuration.nix`)
-  "other-aspect"
+3. SOPS secrets (`./secrets.nix`)
-  "another-aspect"
+4. Custom modules (`../../modules/*.nix`)
-];
+5. Base profiles (`../../profiles/*.nix`)
-```
+6. Input modules (`inputs.<module>.xxxModules.module`)
 
-### Key Conventions
+Home-manager users import profiles in a similar manner.
-- No `specialArgs` — den batteries handle input passing
-- No hostname string comparisons in shared aspects
-- Host-specific config goes in `den.aspects.<hostname>.*`
-- Shared config uses `os` class (applies to both NixOS and darwin)
-- Non-module files go in `_`-prefixed subdirs

-# NixOS Config
-
-Personal Nix flake for four machines:
-
-- `michael` - x86_64 Linux server
-- `tahani` - x86_64 Linux home server / workstation
-- `chidi` - aarch64 Darwin work laptop
-- `janet` - aarch64 Darwin personal laptop
-
-## Repository Map
-
-- `modules/` - flake-parts modules, auto-imported via `import-tree`
-- `modules/hosts/` - per-host composition modules
-- `modules/hosts/_parts/` - host-private leaf modules like hardware, disks, and literal networking
-- `modules/profiles/` - shared host and user profile bundles
-- `modules/_lib/` - local helper functions
-- `modules/_notability/`, `modules/_paperless/` - feature-owned scripts and templates
-- `apps/` - Nushell apps exposed through the flake
-- `secrets/` - SOPS-encrypted secrets
-- `flake.nix` - generated flake entrypoint
-- `modules/dendritic.nix` - source of truth for flake inputs and `flake.nix` generation
-
-## How It Is Structured
-
-This repo uses `den` and organizes configuration around aspects instead of putting everything directly in host files.
-
-- shared behavior lives in `den.aspects.<name>.<class>` modules under `modules/*.nix`
-- the machine inventory lives in `modules/inventory.nix`
-- shared bundles live in `modules/profiles/{host,user}/`
-- host composition happens in `modules/hosts/<host>.nix`
-- host-private imports live in `modules/hosts/_parts/<host>/` and stay limited to true machine leaf files
-- feature-owned services live in top-level modules like `modules/gitea.nix`, `modules/notability.nix`, and `modules/paperless.nix`
-- user-level config mostly lives in Home Manager aspects
-
-Common examples:
-
-- `modules/core.nix` - shared Nix and shell foundation
-- `modules/dev-tools.nix` - VCS, language, and developer tooling
-- `modules/network.nix` - SSH, fail2ban, and tailscale aspects
-- `modules/gitea.nix` - Gitea, Litestream, and backup stack for `michael`
-- `modules/notability.nix` - Notability ingest services and user tooling for `tahani`
-- `modules/profiles/user/workstation.nix` - shared developer workstation user bundle
-- `modules/hosts/michael.nix` - server composition for `michael`
-- `modules/hosts/tahani.nix` - server/workstation composition for `tahani`
-
-## Common Commands
-
-```bash
-nix run .#build
-nix run .#build -- michael
-nix run .#apply
-nix run .#deploy -- .#tahani
-nix flake check
-alejandra .
-```
-
-## Updating The Flake
-
-`flake.nix` is generated. Update inputs in `modules/dendritic.nix`, then regenerate:
-
-```bash
-nix run .#write-flake
-alejandra .

-## Version Control
-
-- Use `jj` for version control, not `git`.
-- `jj tug` is an alias for `jj bookmark move --from closest_bookmark(@-) --to @-`.
-- Never attempt historically destructive Git commands.
-- Make small, frequent commits.
-- "Commit" means `jj commit`, not `jj desc`; `desc` stays on the same working copy.
-
-## Scripting
-
-- Use Nushell (`nu`) for scripting.
-- Do not use Python, Perl, Lua, awk, or any other scripting language. You are programatically blocked from doing so.
-
-## Workflow
-
-- Always complete the requested work.
-- If there is any ambiguity about what to do next, do NOT make a decision yourself. Stop your work and ask.
-- Do not end with “If you want me to…” or “I can…”; take the next necessary step and finish the job without waiting for additional confirmation.
-- Do not future-proof things. Stick to the original plan.
-- Do not add fallbacks or backward compatibility unless explicitly required by the user. By default, replace the previous implementation with the new one entirely.
-
-## Validation
-
-- Do not ignore failing tests or checks, even if they appear unrelated to your changes.
-- After completing and validating your work, the final step is to run the project's full validation and test commands and ensure they all pass.

----
-
-Process the pasted Albanian lesson content and create two `zk` notes: one for lesson material and one for exercises.
-
-<lesson-material>
-$ARGUMENTS
-</lesson-material>
-
-Requirements:
-
-1. Parse the lesson content and produce two markdown outputs:
-   - `material` output: lesson material only.
-   - `exercises` output: exercises and solutions.
-2. Use today's date in both notes (date in title and inside content).
-3. In the `material` output:
-   - Keep clean markdown structure with headings and bullet points.
-   - Do not add a top-level title heading (no `# ...`) because `zk new --title` already sets the note title.
-   - Translate examples, dialogues, and all lesson texts into English when not already translated.
-   - For bigger reading passages, include a word-by-word breakdown.
-   - For declension/conjugation/grammar tables, provide a complete table of possibilities relevant to the topic.
-   - Spell out numbers only when the source token is Albanian; do not spell out English numbers.
-4. In the `exercises` output:
-   - Include every exercise in markdown.
-   - Do not add a top-level title heading (no `# ...`) because `zk new --title` already sets the note title.
-   - Translate each exercise to English.
-   - Solve all non-free-writing tasks (multiple choice, fill in the blanks, etc.) and include example solutions.
-   - For free-writing tasks, provide expanded examples using basic vocabulary from the lesson (if prompted for 3, provide 10).
-   - Translate free-writing example answers into English.
-   - Spell out numbers only when the source token is Albanian; do not spell out English numbers.
-
-Execution steps:
-
-1. Generate two markdown contents in memory (do not create temporary files):
-   - `MATERIAL_CONTENT`
-   - `EXERCISES_CONTENT`
-2. Set `TODAY="$(date +%F)"` once and reuse it for both notes.
-3. Create note 1 with `zk` by piping markdown directly to stdin:
-   - Title format: `Albanian Lesson Material - YYYY-MM-DD`
-   - Command pattern:
-     - `printf "%s\n" "$MATERIAL_CONTENT" | zk new --interactive --title "Albanian Lesson Material - $TODAY" --date "$TODAY" --print-path`
-4. Create note 2 with `zk` by piping markdown directly to stdin:
-   - Title format: `Albanian Lesson Exercises - YYYY-MM-DD`
-   - Command pattern:
-     - `printf "%s\n" "$EXERCISES_CONTENT" | zk new --interactive --title "Albanian Lesson Exercises - $TODAY" --date "$TODAY" --print-path`
-5. Print both created note paths and a short checklist of what was included.
-
-If no lesson material was provided in `$ARGUMENTS`, stop and ask the user to paste it.

----
-description: Triage inbox one message at a time with himalaya only
----
-
-Process email with strict manual triage using Himalaya only.
-
-Hard requirements:
-- Use `himalaya` for every mailbox interaction (folders, listing, reading, moving, deleting, attachments).
-- Process exactly one message ID at a time. Never run bulk actions on multiple IDs.
-- Do not use pattern-matching commands or searches (`grep`, `rg`, `awk`, `sed`, `himalaya envelope list` query filters, etc.).
-- Always inspect current folders first, then triage.
-- Treat this as a single deterministic run over a snapshot of message IDs discovered during this run.
-- Ingest valuable document attachments into Paperless (see Document Ingestion section below).
-
-Workflow:
-1. Run `himalaya folder list` first and use those folders as the primary taxonomy.
-2. Use this existing folder set as defaults when it fits:
-   - `INBOX`
-    - `Correspondence`
-    - `Orders and Invoices`
-    - `Payments`
-    - `Outgoing Shipments`
-    - `Newsletters and Marketing`
-    - `Junk`
-    - `Deleted Messages`
-3. Determine source folder:
-   - If `$ARGUMENTS` is a single known folder name (matches a folder from step 1), use that as source.
-   - Otherwise use `INBOX`.
-4. Build a run scope safely:
-   - List with fixed page size `20` and JSON output: `himalaya envelope list -f "<source>" -p 1 -s 20 --output json`.
-   - Start at page `1`. Enumerate IDs in returned order.
-   - Process each ID fully before touching the next ID.
-   - Keep an in-memory reviewed set for this run to avoid reprocessing IDs already handled or intentionally left untouched.
-   - When all IDs on the current page are in the reviewed set, advance to the next page.
-   - Stop when a page returns fewer results than the page size (end of folder) and all its IDs are in the reviewed set.
-5. For each single envelope ID, do all checks before any move/delete:
-    - Check envelope flags from the JSON listing (seen/answered/flagged) before reading.
-    - Read the message: `himalaya message read -f "<source>" <id>`.
-    - If needed for classification or ingestion, download attachments: `himalaya attachment download -f "<source>" <id> --dir /tmp/himalaya-triage`.
-    - If the message qualifies for document ingestion (see Document Ingestion below), copy eligible attachments to the Paperless consume directory before cleanup.
-    - Always `rm` downloaded files from `/tmp/himalaya-triage` after processing (whether ingested or not).
-    - Move: `himalaya message move -f "<source>" "<destination>" <id>`.
-    - Delete: `himalaya message delete -f "<source>" <id>`.
-6. Classification precedence (higher rule wins on conflict):
-    - **Actionable and unhandled** — if the message needs a reply, requires manual payment, needs a confirmation, or demands any human action, AND has NOT been replied to (no `answered` flag), leave it in the source folder untouched. This is the highest-priority rule: anything that still needs attention stays in `INBOX`.
-    - Human correspondence already handled — freeform natural-language messages written by a human that have been replied to (`answered` flag set): move to `Correspondence`.
-    - Human communication not yet replied to but not clearly actionable — when in doubt whether a human message requires action, leave it untouched.
-    - Clearly ephemeral automated/system message (alerts, bot/status updates, OTP/2FA, password reset codes, login codes) with no archival value: move to `Deleted Messages`.
-    - Automatic payment transaction notifications (charge/payment confirmations, receipts, failed-payment notices, provider payment events such as Klarna/PayPal/Stripe) that are purely informational and require no action: move to `Payments`.
-    - Subscription renewal notifications (auto-renew reminders, "will renew soon", price-change notices without a concrete transaction) are operational alerts, not payment records: move to `Deleted Messages`.
-    - Installment plan activation notifications (e.g. Barclays installment purchase confirmations) are operational confirmations, not payment records: move to `Deleted Messages`.
-    - "Kontoauszug verfügbar/ist online" notifications are availability alerts, not payment records: move to `Deleted Messages`.
-    - Orders/invoices/business records: move to `Orders and Invoices`.
-    - Shipping/tracking notifications (dispatch confirmations, carrier updates, delivery ETAs) without invoice or order-document value: move to `Deleted Messages`.
-    - Marketing/newsletters: move to `Newsletters and Marketing`.
-    - Delivery/submission confirmations for items you shipped outbound: move to `Outgoing Shipments`.
-    - Long-term but uncategorized messages: create a concise new folder and move there.
-7. Folder creation rule:
-   - Create a new folder only if no existing folder fits and the message should be kept.
-   - Naming constraints: concise topic name, avoid duplicates, and avoid broad catch-all names.
-   - Command: `himalaya folder add "<new-folder>"`.
-
-Document Ingestion (Paperless):
-- **Purpose**: Automatically archive valuable document attachments into Paperless via its consumption directory.
-- **Ingestion path**: `/var/lib/paperless/consume/inbox-triage/`
-- **When to ingest**: Only for messages whose attachments have long-term archival value. Eligible categories:
-  - Invoices, receipts, and billing statements (messages going to `Orders and Invoices` or `Payments`)
-  - Contracts, agreements, and legal documents
-  - Tax documents, account statements, and financial summaries
-  - Insurance documents and policy papers
-  - Official correspondence with document attachments (government, institutions)
-- **When NOT to ingest**:
-  - Marketing emails, newsletters, promotional material
-  - Shipping/tracking notifications without invoice attachments
-  - OTP codes, login alerts, password resets, ephemeral notifications
-  - Subscription renewal reminders without actual invoices
-  - Duplicate documents already seen in this run
-  - Inline images, email signatures, logos, and non-document attachments
-- **Eligible file types**: PDF, PNG, JPG/JPEG, TIFF, WEBP (documents and scans only). Skip archive files (ZIP, etc.), calendar invites (ICS), and other non-document formats.
-- **Procedure**:
-  1. After downloading attachments to `/tmp/himalaya-triage`, check if any are eligible documents.
-  2. Copy eligible files: `cp /tmp/himalaya-triage/<filename> /var/lib/paperless/consume/inbox-triage/`
-  3. If multiple messages could produce filename collisions, prefix the filename with the message ID: `<id>-<filename>`.
-  4. Log each ingested file in the action log at the end of the run.
-- **Conservative rule**: When in doubt whether an attachment is worth archiving, skip it. Paperless storage is cheap, but noise degrades searchability. Prefer false negatives over false positives for marketing material, but prefer false positives over false negatives for anything that looks like a financial or legal document.
-
-Execution rules:
-- Never perform bulk operations. One message ID per `read`, `move`, `delete`, and attachment command.
-- Always use page size 20 for envelope listing (`-s 20`).
-- If any single-ID command fails, log the error and continue with the next unreviewed ID.
-- Never skip reading message content before deciding.
-- Keep decisions conservative: when in doubt about whether something needs action, leave it in `INBOX`.
-- Never move or delete unhandled actionable messages.
-- Never move human communications that haven't been replied to, unless clearly non-actionable.
-- Define "processed" as "reviewed once in this run" (including intentionally untouched human messages).
-- Include only messages observed during this run's listings; if new mail arrives mid-run, leave it for the next run.
-- Report a compact action log at the end with:
-  - source folder,
-  - total reviewed IDs,
-  - counts by action (untouched/moved-to-folder/deleted),
-  - per-destination-folder counts,
-  - created folders,
-  - documents ingested to Paperless (count and filenames),
-  - short rationale for non-obvious classifications.

-## What to Remember
-
-### 1. Procedures (Rules & Workflows)
-Explicit rules that should always be followed:
-- "Never commit directly to main - always use feature branches"
-- "Always run lint before tests"
-- "Use conventional commits format"
-
-### 2. Preferences (Style & Conventions)
-Project and user coding style:
-- "Prefer functional components over class components"
-- "Use early returns instead of nested conditionals"
-- "Always add JSDoc to exported functions"
-
-### 3. Architecture & Context
-How the codebase works and why:
-- "Auth system was refactored in v2.0 - old patterns deprecated"
-- "The monorepo used to have 3 modules before consolidation"
-- "This pagination bug was fixed before - similar to PR #234"
-
-## Memory Scopes
-
-**Project-scoped** (\`scope: "project"\`):
-- Build/test/lint commands
-- Architecture and key directories
-- Team conventions specific to this codebase
-- Technology stack and framework choices
-- Known issues and their solutions
-
-**User-scoped** (\`scope: "user"\`):
-- Personal coding preferences across all projects
-- Communication style preferences
-- General workflow habits
-
-## Research Approach
-
-This is a **deep research** initialization. Take your time and be thorough (~50+ tool calls). The goal is to genuinely understand the project, not just collect surface-level facts.
-
-**What to uncover:**
-- Tech stack and dependencies (explicit and implicit)
-- Project structure and architecture
-- Build/test/deploy commands and workflows
-- Contributors & team dynamics (who works on what?)
-- Commit conventions and branching strategy
-- Code evolution (major refactors, architecture changes)
-- Pain points (areas with lots of bug fixes)
-- Implicit conventions not documented anywhere
-
-## Research Techniques
-
-### File-based
-- README.md, CONTRIBUTING.md, AGENTS.md, CLAUDE.md
-- Package manifests (package.json, Cargo.toml, pyproject.toml, go.mod)
-- Config files (.eslintrc, tsconfig.json, .prettierrc)
-- CI/CD configs (.github/workflows/)
-
-### Git-based
-- \`git log --oneline -20\` - Recent history
-- \`git branch -a\` - Branching strategy
-- \`git log --format="%s" -50\` - Commit conventions
-- \`git shortlog -sn --all | head -10\` - Main contributors
-
-### Explore Agent
-Fire parallel explore queries for broad understanding:
-\`\`\`
-Task(explore, "What is the tech stack and key dependencies?")
-Task(explore, "What is the project structure? Key directories?")
-Task(explore, "How do you build, test, and run this project?")
-Task(explore, "What are the main architectural patterns?")
-Task(explore, "What conventions or patterns are used?")
-\`\`\`
-
-## How to Do Thorough Research
-
-**Don't just collect data - analyze and cross-reference.**
-
-Bad (shallow):
-- Run commands, copy output
-- List facts without understanding
-
-Good (thorough):
-- Cross-reference findings (if inconsistent, dig deeper)
-- Resolve ambiguities (don't leave questions unanswered)
-- Read actual file content, not just names
-- Look for patterns (what do commits tell you about workflow?)
-- Think like a new team member - what would you want to know?
-
-## Saving Memories
-
-Use the \`supermemory\` tool for each distinct insight:
-
-\`\`\`
-supermemory(mode: "add", content: "...", type: "...", scope: "project")
-\`\`\`
-
-**Types:**
-- \`project-config\` - tech stack, commands, tooling
-- \`architecture\` - codebase structure, key components, data flow
-- \`learned-pattern\` - conventions specific to this codebase
-- \`error-solution\` - known issues and their fixes
-- \`preference\` - coding style preferences (use with user scope)
-
-**Guidelines:**
-- Save each distinct insight as a separate memory
-- Be concise but include enough context to be useful
-- Include the "why" not just the "what" when relevant
-- Update memories incrementally as you research (don't wait until the end)
-
-**Good memories:**
-- "Uses Bun runtime and package manager. Commands: bun install, bun run dev, bun test"
-- "API routes in src/routes/, handlers in src/handlers/. Hono framework."
-- "Auth uses Redis sessions, not JWT. Implementation in src/lib/auth.ts"
-- "Never use \`any\` type - strict TypeScript. Use \`unknown\` and narrow."
-- "Database migrations must be backward compatible - we do rolling deploys"
-
-## Upfront Questions
-
-Before diving in, ask:
-1. "Any specific rules I should always follow?"
-2. "Preferences for how I communicate? (terse/detailed)"
-
-## Reflection Phase
-
-Before finishing, reflect:
-1. **Completeness**: Did you cover commands, architecture, conventions, gotchas?
-2. **Quality**: Are memories concise and searchable?
-3. **Scope**: Did you correctly separate project vs user knowledge?
-
-Then ask: "I've initialized memory with X insights. Want me to continue refining, or is this good?"
-
-## Your Task
-
-1. Ask upfront questions (research depth, rules, preferences)
-2. Check existing memories: \`supermemory(mode: "list", scope: "project")\`
-3. Research based on chosen depth
-4. Save memories incrementally as you discover insights
-5. Reflect and verify completeness
-6. Summarize what was learned and ask if user wants refinement

-   - GOOD tags for a server hosting invoice: "Invoice", "Hosting"
-   - BAD tags for a server hosting invoice: "IBAN", "VAT", "Bank account" — these are just details that appear on any invoice.
-2. Pick 1-4 tags maximum. Fewer is better. Every tag must add distinct, meaningful categorisation value.
-3. All tags must be in English.
-4. Never tag based on formatting details, payment methods, reference numbers, or boilerplate text.
-
-The content is likely in {{.Language}}, but tags must always be in English.
-
-<available_tags>

-I will provide you with the content of a document that has been partially read by OCR (so it may contain errors).
-Your task is to generate a clear, consistent document title for use in paperless-ngx.
-
-Title format: "YYYY-MM-DD - Sender - Description"
-- YYYY-MM-DD: The document date (issue date, statement date, etc.). Use the most specific date available. If no date is found, omit the date prefix.
-- Sender: The company, organisation, or person who sent/issued the document. Use their common short name (e.g. "Hetzner" not "Hetzner Online GmbH").
-- Description: A brief description of what the document is (e.g. "Server hosting invoice", "Payslip January", "Employment contract", "Tax assessment 2024"). Keep it concise but specific enough to distinguish from similar documents.
-
-Examples:
-- "2025-03-01 - Hetzner - Server hosting invoice"
-- "2024-12-15 - Techniker Krankenkasse - Health insurance statement"
-- "2024-06-30 - Acme Corp - Payslip June"
-- "2024-01-10 - Finanzamt Berlin - Tax assessment 2023"
-
-Rules:
-1. Always write the title in English, regardless of the document language.
-2. Keep the description part under 6 words.
-3. If the original title contains useful information, use it to inform your suggestion.
-4. Respond only with the title, without any additional information.
