+title = "Add contact footer to all service front-ends"
+priority = 3
+status = "todo"
+ticket_type = "task"
+dependencies = []
++++
+## Background
+
+The root `TODO.md` calls for a footer on every service front-end with contact info:
+
+> Contact: `<site>@elijah.run`
+
+Where `<site>` depends on the service.
+
+## Target services and email addresses
+
+| Service | Front-end type | Contact email |
+|---|---|---|
+| `quotesdb` | Yew (Rust/Wasm) | `quotes@elijah.run` |
+| `edu` | mdbook static site | `vibedbooks@elijah.run` |
+| Blog editor | Yew (not yet built) | `editor@elijah.run` |
+
+## Implementation
+
+### quotesdb/ui
+
+Add a `Footer` component to the Yew app:
+
+1. Create `quotesdb/ui/src/components/footer.rs` (or add inline to `app.rs`).
+2. Render a `<footer>` element at the bottom of every page with the text:
+   `Contact: quotes@elijah.run`
+3. Use an `<a href="mailto:quotes@elijah.run">` tag so it is clickable.
+4. Include the footer in the top-level layout so every route shows it.
+
+### edu (mdbook)
+
+mdbook supports injecting HTML before/after the content via the `[output.html]` table in `book.toml`:
+
+```toml
+[output.html]
+additional-js = []
+additional-css = []
+```
+
+Or use the `before-content` / `after-content` HTML templates. More precisely, create `edu/theme/footer.hbs` with the footer markup and register it in `book.toml`.
+
+Alternatively (simpler): add a `theme/` directory with an `index.hbs` that extends the default template and appends the footer. The mdbook docs for custom theming describe this approach.
+
+Simplest option: add `footer.html` fragment via `[output.html] additional-js` hack, or just add a sentence at the bottom of each page — but that is not scalable.
+
+**Recommended approach for mdbook:** Use mdbook's `theme/index.hbs` override (copy the default from the mdbook source) and add the footer HTML before the closing `</body>` tag:
+
+```html
+<footer style="text-align:center;padding:1em;opacity:0.6">
+  Contact: <a href="mailto:vibedbooks@elijah.run">vibedbooks@elijah.run</a>
+</footer>
+```
+
+## Files involved
+
+- `edu/theme/index.hbs` (new — copy from mdbook default, add footer)
+- `edu/book.toml` (may need `[output.html] theme = "theme"` entry)
+- `quotesdb/ui/src/components/footer.rs` (new) or similar

+title = "Add justfiles for all projects with lint, check, build, build-release, and release recipes"
+priority = 5
+status = "todo"
+ticket_type = "task"
+dependencies = []
++++
+## Background
+
+The root `TODO.md` calls for each project in the mono-repo to have a `justfile` with standard recipe names so that any contributor can run the same commands regardless of project type. `just` is a command runner similar to Make but with cleaner syntax.
+
+## Recipes to add per project
+
+| Recipe | What it runs |
+|---|---|
+| `lint` | Auto-format: `cargo fmt`, `tofu fmt`, `mdbook build` (edu), etc. |
+| `check` | Static checks: `cargo check && cargo clippy`, `tofu validate && tofu plan`, etc. |
+| `build` | Dev build: `cargo build`, `trunk build`, `mdbook build` |
+| `build-release` | Optimised binary or bundle: `cargo build --release`, `trunk build --release` |
+| `release` | Deploy/publish: `tofu apply`, `wrangler deploy` (where applicable) |
+
+Not every project needs every recipe; stub missing ones with an error or a no-op comment.
+
+## Per-project breakdown
+
+### `nbd/justfile`
+- `lint`: `cargo fmt`
+- `check`: `cargo check && cargo clippy && cargo test`
+- `build`: `cargo build`
+- `build-release`: `cargo build --release`
+- `release`: n/a (CLI tool, no deployment)
+
+### `edu/justfile`
+- `lint`: `mdbook build` (build validates the content)
+- `check`: `mdbook build`
+- `build`: `mdbook build`
+- `build-release`: same as `build` (mdbook has no separate release mode)
+- `release`: TBD — CF Pages auto-deploys from main branch once infra is configured (see edu deployment ticket)
+
+### `quotesdb/api/justfile`
+- `lint`: `cargo fmt`
+- `check`: `cargo check && cargo clippy`
+- `build`: `cargo build`
+- `build-release`: `cargo build --release`
+- `release`: `wrangler deploy` (or `tofu apply` from `infra/`)
+
+### `quotesdb/ui/justfile`
+- `lint`: `cargo fmt`
+- `check`: `cargo check && cargo clippy`
+- `build`: `trunk build`
+- `build-release`: `trunk build --release`
+- `release`: CF Pages auto-deploys from main branch once infra is configured
+
+## Files to create
+
+- `nbd/justfile`
+- `edu/justfile`
+- `quotesdb/api/justfile`
+- `quotesdb/ui/justfile`
+
+## Conventions
+
+- Recipe names must be consistent across all projects (`lint`, `check`, `build`, `build-release`, `release`).
+- Commands are run from the directory containing the `justfile`, so paths are relative to the project directory.
+- Add a comment above each recipe explaining what it does.
+- Check whether the `just` package is already in each project's Nix dev shell (`flake.nix`); add it if missing.

++++
+## Background
+
+From `edu/TODO.md`: Hands-on: Creating and training a simple LLM.
+
+A practical course on building a small language model from scratch in Rust, covering tokenisation, the Transformer architecture, and a training loop. The goal is deep understanding rather than production scale.
+
+## Content outline (suggested)
+
+### Part 1 — What is a Language Model?
+1. Predicting the next token: the core task
+2. Tokenisation: BPE, byte-level, character-level — pick character-level for simplicity
+3. Exercise 1: Build a character-level tokeniser in Rust
+
+### Part 2 — The Transformer Architecture
+4. Embeddings and positional encoding
+5. Self-attention: queries, keys, values — the attention formula
+6. Multi-head attention
+7. Feed-forward sublayers, residual connections, layer norm
+8. Exercise 2: Implement a single attention head in Rust (no ML framework)
+
+### Part 3 — Assembling the Model
+9. Stacking Transformer blocks into a decoder-only LM
+10. Using `candle` (Hugging Face's Rust ML framework) for tensor ops and autodiff
+11. Exercise 3: Define a small GPT-like model in `candle`
+
+### Part 4 — Training
+12. Cross-entropy loss for next-token prediction
+13. The training loop: forward pass, loss, backward pass, optimizer step
+14. Exercise 4: Train on a small text corpus (e.g., Shakespeare or a short book)
+15. Exercise 5: Sample from the model and observe output quality vs. training steps
+
+### Part 5 — Reflection
+16. What limits this model? Scale, data, compute
+17. Pointers to real LLM training (GPT-2, LLaMA, Mistral)
+18. Further reading

+priority = 5
+status = "todo"
+ticket_type = "project"
+dependencies = []
++++
+## Background
+
+From `edu/TODO.md`:
+- Host the mdbook on Cloudflare Pages
+- Host on vibebooks.elijah.run
+- Create an `infra/` directory containing opentofu configs for the above
+- Add a big disclaimer about the content being AI-generated
+
+## Sub-tasks
+
+### 1. Add AI-generated disclaimer
+
+Add a prominent disclaimer page or preface to the mdbook. The disclaimer should say (in the user's words):
+> these [chapters] are AI generated and not intended to be definitive, trustworthy, or even good, just an experiment in generating tailored educational content about topics I am interested in but not sure where to start, and with a practical focus on exercises with Rust since that is the language I use most often
+
+Placement options:
+- A dedicated `src/disclaimer.md` page added first in `src/SUMMARY.md`
+- Or a callout block at the top of every chapter (requires mdbook preprocessor)
+- Recommended: `src/disclaimer.md` as the first page, with a short note in each chapter's preamble
+
+### 2. Create `edu/infra/` with OpenTofu configs
+
+Follow the pattern from `quotesdb/infra/` (Cloudflare provider, tofu modules).
+
+Minimal resources:
+- `cloudflare_pages_project` — create the Pages project named `vibedbooks`
+- `cloudflare_pages_domain` — bind `vibebooks.elijah.run` to the Pages project
+- `cloudflare_record` — CNAME DNS record pointing `vibebooks` at the Pages subdomain
+
+File layout:
+```
+edu/infra/
+├── main.tf          # provider config, cloudflare_pages_project
+├── dns.tf           # cloudflare_record and cloudflare_pages_domain
+├── variables.tf     # cloudflare_account_id, cloudflare_zone_id, etc.
+├── outputs.tf       # pages subdomain URL
+└── .gitignore       # *.tfstate, .terraform/
+```
+
+All `resource` and `data` blocks must have a comment explaining their purpose (per CLAUDE.md conventions).
+
+### 3. Configure mdbook build for CF Pages
+
+Cloudflare Pages can auto-build mdbook sites if given the right build command and output directory. Set in the Pages project config:
+- Build command: `mdbook build`
+- Build output directory: `book`
+- Root directory: `edu/`
+
+Alternatively, use a CI/CD pipeline (GitHub Actions / Gitea Actions) to build and push to the Pages project via `wrangler pages deploy`.
+
+### 4. Add edu/justfile
+
+Add a `release` recipe to `edu/justfile` (see justfiles ticket) that triggers the Pages deployment once infra is configured.
+
+## Relevant files
+
+- `edu/book.toml` — mdbook configuration
+- `edu/src/SUMMARY.md` — add disclaimer page
+- `edu/src/disclaimer.md` (new)
+- `edu/infra/` (new directory)
+- Cloudflare dashboard: Pages project, DNS zone `elijah.run`
+
+## Validation
+
+- `tofu validate && tofu plan` from `edu/infra/`
+- `mdbook build` from `edu/` — builds without errors
+- After deploy: `curl -I https://vibebooks.elijah.run` returns 200

+## Background
+
+From `edu/TODO.md`: write a chapter about how to structure a co-op profit-sharing worker-owned business.
+
+This is a conceptual/informational chapter, not a Rust hands-on. It fits naturally in the Vibed Learning book as a practical guide for engineers who might want to start or join a worker cooperative.
+
+## Content outline (suggested)
+
+1. **What is a worker cooperative?** — definition, historical examples, how they differ from traditional businesses
+2. **Legal structures** — co-op incorporation options by jurisdiction (US LCA/LLC, UK LLP, etc.), relevant legislation
+3. **Profit sharing models** — patronage dividends, equal shares, labor-hour weighted, hybrid approaches
+4. **Governance** — one-member-one-vote, board structure, decision-making processes
+5. **Practical startup steps** — founding documents, initial capital, operating agreements
+6. **Case studies** — Mondragon, REI, Cooperative Home Care Associates, tech co-ops (Loomio, etc.)
+7. **Resources and further reading**
+
+## File to create
+
+- `edu/src/co-op.md`
+- Add to `edu/src/SUMMARY.md` under a new `# Business` section (or `# Other Topics`)

+title = "Add --xml output format that wraps each ticket section in XML tags"
+priority = 4
+status = "todo"
+ticket_type = "feature"
+dependencies = []
++++
+## Background
+
+From `nbd/TODO.md`:
+
+> Add a `--xml` output format that prints tickets with XML around each section to make it easier to parse metadata.
+
+Unlike `--json` (which is a complete, structured parse), the XML format adds lightweight tags around each metadata field in the human-readable output. This makes it trivial for scripts to extract specific fields using simple text tools (e.g., `grep`, `sed`, XPath) without pulling in a full JSON parser.
+
+## Intended XML format
+
+For a single ticket (`nbd read <id> --xml`):
+
+```xml
+<ticket>
+  <id>a3f9c2</id>
+  <title>Fix login bug</title>
+  <priority>8</priority>
+  <status>in_progress</status>
+  <type>bug</type>
+  <dependencies>
+    <dep>b7d41e</dep>
+    <dep>c9e823</dep>
+  </dependencies>
+  <body>Users cannot log in with email addresses containing +</body>
+</ticket>
+```
+
+For a list (`nbd list --xml`):
+
+```xml
+<tickets>
+  <ticket>...</ticket>
+  <ticket>...</ticket>
+</tickets>
+```
+
+## Implementation
+
+### `src/main.rs`
+
+Add a global `--xml` flag to the `Cli` struct, parallel to `--json`:
+
+```rust
+/// Output XML instead of a human-readable table.
+#[arg(long, global = true)]
+xml: bool,
+```
+
+Precedence: if both `--json` and `--xml` are supplied, `--json` wins (or return an error — TBD, but JSON-first is simpler).
+
+Pass `cli.xml` through `dispatch` to every command handler, alongside `cli.json`.
+
+Each command handler signature gains an `xml: bool` parameter. When `xml` is true and `json` is false, call the new `display::print_ticket_xml` / `display::print_list_xml` functions.
+
+### `src/display.rs`
+
+Add:
+
+- `format_ticket_xml(ticket: &Ticket) -> String` — serialises a single ticket as XML
+- `print_ticket_xml(ticket: &Ticket)` — wraps `format_ticket_xml` + `println!`
+- `format_list_xml(tickets: &[Ticket]) -> String` — wraps list in `<tickets>`
+- `print_list_xml(tickets: &[Ticket])`
+
+XML escaping: at minimum, escape `&`, `<`, `>`, `"`, `'` in field values. Use a small helper `xml_escape(s: &str) -> String` rather than pulling in an XML crate.
+
+For `dependencies`: render each as a `<dep>` child element.
+
+### `src/tests.rs`
+
+Add unit tests:
+- `format_ticket_xml` with a ticket that has special characters in the title and body (`&`, `<`, `>`)
+- `format_ticket_xml` with empty dependencies
+- `format_ticket_xml` with multiple dependencies
+- `format_list_xml` with zero and multiple tickets
+
+### `tests/integration.rs`
+
+Add integration tests:
+- `nbd read <id> --xml` returns valid XML containing the ticket's fields
+- `nbd list --xml` returns valid XML wrapping multiple tickets
+- `nbd create ... --xml` returns the created ticket as XML
+- `nbd update ... --xml` returns the updated ticket as XML
+
+## Scope
+
+All commands that support `--json` should also support `--xml`:
+- `nbd create`
+- `nbd read`
+- `nbd list`
+- `nbd update`
+- `nbd ready`
+- `nbd next`
+- `nbd archive`
+- `nbd migrate`
+- `nbd graph` (the JSON graph format has a defined structure; XML should mirror it)
+- `nbd claude-md` (wrap snippet in `<snippet>` tag)
+- `nbd init` (wrap root path in `<init>`)
