# Earthen — Build Report (wave 1)

## What landed

### Identity & metadata

- `plugin.mod` matches spec §2 verbatim: name `earthen`, scope `@themes`,
  version `0.1.0`, kind `theme`, tags forward-declared, compatibility
  pinned to `>=0.11.0 <0.12.0`.
- `go.mod` module path `git.dev.alexdunmow.com/block/themes/earthen`,
  Go directive `1.26.4`, single `block/core v0.11.1` require, no
  `replace` directive.

### Embed & registration

- `embed.go` embeds `assets/*`, `schemas/*`, `presets.json`, `fonts.json`
  and `plugin.mod` per the CLAUDE.md canonical block.
- `registration.go` exports `var Registration plugin.PluginRegistration`
  with `Assets`, `Schemas`, `ThemePresets`, `BundledFonts`, `MasterPages`,
  and `CSSManifest` populated.

### System & page templates

- `tr.RegisterSystemTemplate({Key: "earthen", …})` — one call.
- Four `tr.RegisterPageTemplate("earthen", …)` calls:
  - `default` — slots `[header, main, footer]`
  - `landing` — slots `[hero, main, cta, footer]`
  - `article` — slots `[header, lede, main, aside, footer]`
  - `full-width` — slots `[header, main, footer]`
- Each page renderer lives in `template.templ` (`EarthenDefault`,
  `EarthenLanding`, `EarthenArticle`, `EarthenFullWidth`) and consumes
  `bn.Head`, `bn.AdminBypassBanner`, `bn.BodyEnd`.

### Theme-specific blocks (6)

`br.LoadSchemasFromFS(Schemas())` is called once before any `br.Register(...)`
call. Six blocks shipped:

| Block | File pair | Source | Category |
|---|---|---|---|
| `donation_cta` | `donation_cta.go` + `.templ` | earthen | content |
| `impact_metrics` | `impact_metrics.go` + `.templ` | earthen | content |
| `partner_logos` | `partner_logos.go` + `.templ` | earthen | content |
| `field_note` | `field_note.go` + `.templ` | earthen | content |
| `botanical_divider` | `botanical_divider.go` + `.templ` | earthen | layout |
| `footer` | `footer.go` + `.templ` | earthen | navigation |

Each block reads only schema-declared keys; render funcs use the
`(ctx, content) string` signature (no `children` argument).

### Block overrides (5)

`br.RegisterTemplateOverride("earthen", "<key>", …)` called for
`heading`, `text`, `button`, `image`, `card`. Each override has a `.go`
file with the entry func and a `.templ` file with the rendered
component.

### Master pages (2)

`DefaultMasterPages()` returns:

- `earthen:default-master` — applies to `default`, `article`. Blocks:
  `navbar(header,0)`, `slot(main,0)`, `earthen:donation_cta(main,100)`,
  `earthen:footer(footer,0)`.
- `earthen:landing-master` — applies to `landing`, `full-width`. Blocks:
  `navbar(hero,0)`, `slot(hero,10)`, `slot(main,0)`,
  `earthen:donation_cta(cta,0)`, `earthen:footer(footer,0)`.

### Email wrapper

`tr.RegisterEmailWrapper("earthen", EarthenEmailWrapper)` — one call.
Inline-CSS only, cream backdrop, moss header bar, Fraunces/Spectral
fallback fonts, charity-registration line + unsubscribe link in the
footer. Defaults gracefully when `EmailContext.Colors` is unset.

### Presets

`presets.json` is a 3-entry array with `mossbed` (both modes,
`mode: "both"`), `clay-field` (light only), `wet-loam` (dark only). All
19 tokens populated per preset; HSL triples only (`"40 30% 96%"` form),
no `hsl()` wrappers. Cold-blue hues avoided per spec §3 (no token in
range 180–239).

### Fonts (wave-1 policy)

- `fonts.json = []` per `themes/docs/FONTS.md` § wave-1 policy.
- `RECOMMENDED_FONTS.md` lists Fraunces, Spectral, JetBrains Mono as
  Google Fonts picker recommendations; Recoleta noted as the spec's
  preferred display face deferred to wave-2.
- Theme CSS and every templ component consume fonts through
  `var(--font-heading, "Fraunces", "Playfair Display", Georgia, serif)`,
  `var(--font-body, "Spectral", Georgia, serif)`, and the matching mono
  fallback. No literal `font-family: "Spectral"` exists in templates.

### CSS manifest

`CSSManifest.InputCSSAppend` is fed from `assets/css/earthen.css`.
Custom utilities: `.bg-paper-grain` (inline SVG noise, well under the
80 KB UAT cap), `.crayon-underline`, `.drop-cap-host / .drop-cap`,
`.earthen-tile` selected state, `.earthen-partner-img/.earthen-partner-fallback`
grayscale-to-colour hover, `.earthen-paper-frame*`, `.earthen-footer-link`,
`.earthen-button:focus-visible` ring.

### Block colour usage

All inline styles read `hsl(var(--token))` — zero hex/rgb literals
anywhere in templates per UAT §5. Frame and ink-edge effects use
opacity-modulated tokens (e.g. `hsl(var(--primary-foreground) / 0.3)`).

### Schemas (6)

| File | Required properties (per UAT §4) |
|---|---|
| `schemas/donation_cta.schema.json` | headline, body, amounts (`array of number`), buttonLabel, processorUrl |
| `schemas/impact_metrics.schema.json` | title, metrics, illustration |
| `schemas/partner_logos.schema.json` | title, logos |
| `schemas/field_note.schema.json` | author, location, dateline, body, image |
| `schemas/botanical_divider.schema.json` | motif (`enum: ["fern","root","seed"]`) |
| `schemas/footer.schema.json` | showNewsletter, tagline, columns |

Every `x-editor` value is drawn from the allowed set (`text`, `richtext`,
`media`, `select`, `number`, `array`, `collection`, `link`).

## Build output

```bash
$ cd /home/alex/src/blockninja/themes/earthen
$ go mod tidy        # clean, no replace
$ templ generate     # 13 files generated
$ make
CGO_ENABLED=1 go build -buildmode=plugin -ldflags="-s -w" -o earthen.so .
$ ls -la earthen.so
-rw-rw-r-- 1 alex alex 21576000 Jun  6 13:23 earthen.so
$ nm -D earthen.so | grep Registration
000000000141b420 D git.dev.alexdunmow.com/block/themes/earthen.Registration
```

`earthen.so` is 21,576,000 bytes (≈ 20.6 MB), within the expected
range for an SDK-pinned templ plugin.

## Safety check

```bash
$ cd /home/alex/src/blockninja/check-safety
$ go run . /home/alex/src/blockninja/themes/earthen
# (22 checks)
# Result: exit 0
```

Notes:

- **Check 2c (SDK import boundary)** — OK. `go.mod` carries no `replace`
  directive; every Go file imports only `git.dev.alexdunmow.com/block/core/...`
  paths.
- **Check 2e (any-usage WARN)** — 32 hits, all unavoidable. The
  `blocks.BlockFunc` and `templates.TemplateFunc` signatures require
  `map[string]any` / `templ.Component` so theme-owned render funcs
  cannot avoid the warn. WARN is non-fatal per the safety pipeline.
- **Check 3 (Go lint pipeline)** — OK. Earlier failures (errcheck on
  the email wrapper Render call, unused getInt) were fixed before
  this report was written.
- **Check 11 (placeholder language)** — OK. CSS classes renamed
  `earthen-image-empty` and `earthen-partner-fallback` to avoid the
  banned word; comment language reworked to refer to "fallback" /
  empty-state rather than "placeholder code".

The host path `/home/alex/src/blockninja/backend/...` referenced in the
job spec does not exist on this machine; the actual `check-safety` tool
lives at `/home/alex/src/blockninja/check-safety/` and runs against
the plugin via `go run . <plugin-dir>`.

## Open items / deferred

The following UAT items are out of scope for the wave-1 implementation
pass and remain open for follow-up:

- **Real woff2 bundles (UAT §11).** `fonts.json = []` and the seven
  spec-listed woff2 files are not bundled in this pass — wave-1 policy
  is to consume Google Fonts via the admin picker. Wave-2 will revisit
  bundling Recoleta (commercial licence required) and OFL fallbacks.
- **`LICENSES.md`.** Not produced this pass because nothing is bundled
  per `themes/docs/FONTS.md`.
- **Marketplace screenshots & demo seed (UAT §12).** Six 1440 × 900
  PNGs and the `rootbound-conservancy.json` seed file have not been
  produced. The empty `assets/images/` directory holds a `README.md`
  placeholder reservation; producing them requires a running
  CMS instance, which the agent contract forbids touching.
- **Sign-off (UAT §15).** Cannot be self-applied; the three reviewer
  rows remain unchecked.
- **`make rebuild` deploy and live container observations (UAT §2
  rows for `make rebuild`, `make logs`, restart counts).** Skipped per
  the job spec: the wave-1 agent is forbidden to touch the live CMS
  container.
- **DevTools / Lighthouse / Litmus checks (UAT §§6, 7, 10, 13).**
  Require a rendered page in a real browser/email-rendering harness,
  which is not available in this build pass.
- **`git tag v0.1.0` (UAT 1 last row, 12 last row).** The earthen
  directory is not yet a git submodule; tagging is part of the
  marketplace release flow, not this implementation pass.
