### Top-level configuration blocks

| Block | Purpose | Required | Merge strategy | Notes |
| --- | --- | --- | --- | --- |
| `metadata` | Payload declarativo principal do componente | true | deep-merge | runtime linkage verified for core flows (component specs, 2026-03-06). |
| `readonlyMode` | Override de readonly no host/runtime | false | override | runtime linkage verified for core flows (component specs, 2026-03-06). |
| `disabledMode` | Override de disabled no host/runtime | false | override | runtime linkage verified for core flows (component specs, 2026-03-06). |
| `visible` | Override de visibilidade no host/runtime | false | override | runtime linkage verified for core flows (component specs, 2026-03-06). |
| `presentationMode` | Renderizacao de apresentacao sem interacao | false | override | runtime linkage verified for core flows (component specs, 2026-03-06). |

### Nested configuration blocks

| Path | Type | Required | Default | Constraints | Notes |
| --- | --- | --- | --- | --- | --- |
| `metadata.controlType` | string | false | n/a | component-defined | Partial; verify per source_of_truth. |
| `metadata.minDate` | string | false | n/a | component-defined | Partial; verify per source_of_truth. |
| `metadata.maxDate` | string | false | n/a | component-defined | Partial; verify per source_of_truth. |
| `metadata.startView` | string | false | n/a | component-defined | Partial; verify per source_of_truth. |
| `metadata.startAt` | unknown | false | n/a | component-defined | Partial; verify per source_of_truth. |
| `metadata.touchUi` | boolean | false | n/a | component-defined | Partial; verify per source_of_truth. |
| `metadata.dateFilter` | string | false | n/a | component-defined | Partial; verify per source_of_truth. |
| `metadata.dateFormat` | string | false | n/a | component-defined | Display order hint; `dd/MM/yyyy` renders day-first and `MM/dd/yyyy` renders month-first. |
| `metadata.displayFormat` | string | false | n/a | component-defined | Display order hint; `dd/MM/yyyy` renders day-first and `MM/dd/yyyy` renders month-first. |
| `metadata.locale` | string | false | host `LOCALE_ID` | BCP 47 locale | Overrides language/locale for this field without being inferred from date order. |
| `metadata.manualInput` | boolean | false | `true` | `false` blocks manual typing without activating readonly field semantics. | Use for locale-sensitive dates where typed strings would be ambiguous. |

### Manual date parsing

- Digitacao manual usa `PraxisNativeDateAdapter` e respeita `metadata.locale`; quando ausente, usa o `LOCALE_ID` do host.
- Em locales nao ingleses, como `pt-BR`, datas numericas sao interpretadas como `dd/MM/yyyy`.
- Em locales ingleses, datas numericas sao interpretadas como `MM/dd/yyyy`.
- `metadata.locale` e ordem de data sao independentes: `displayFormat`, `dateFormat` ou `mask` como `dd/MM/yyyy` habilitam apresentacao day-first; `MM/dd/yyyy` habilita month-first.
- Strings ISO date-only (`YYYY-MM-DD`) sao tratadas como data local, sem deslocamento por timezone.
- Use `metadata.manualInput: false` quando o host quiser bloquear digitacao manual e manter apenas selecao pelo calendario.

### Input bindings (inbound data)

| Binding/Path | Type | Required | Source | Runtime normalization | Notes |
| --- | --- | --- | --- | --- | --- |
| `metadata` | object | true | host-json | component-defined | Primary inbound contract payload. |
| `readonlyMode` | boolean | false | host-runtime | not-yet-verified | Host-level behavioral override. |
| `disabledMode` | boolean | false | host-runtime | not-yet-verified | Host-level behavioral override. |
| `visible` | boolean | false | host-runtime | not-yet-verified | Host-level behavioral override. |
| `presentationMode` | boolean | false | host-runtime | not-yet-verified | Host-level behavioral override. |

### Output events

### External side channels

| Channel | Direction | Contract | Failure mode | Notes |
| --- | --- | --- | --- | --- |
| `host/services/storage` | bidirectional | component-defined | component-defined | Side channels variam por componente e host; verificar em source_of_truth. |

### Host/runtime dependencies

| Dependency | Required | Environment | Purpose | Notes |
| --- | --- | --- | --- | --- |
| `material-datepicker.metadata.ts` | true | browser/dev/prod/ssr | contract resolution | Refer to `projects/praxis-dynamic-fields/src/lib/components/material-datepicker/material-datepicker.metadata.ts`. |
| `material-datepicker.component.ts` | true | browser/dev/prod/ssr | contract resolution | Refer to `projects/praxis-dynamic-fields/src/lib/components/material-datepicker/material-datepicker.component.ts`. |
| `material-field-metadata.interface.ts` | true | browser/dev/prod/ssr | contract resolution | Refer to `projects/praxis-core/src/lib/models/material-field-metadata.interface.ts`. |
| `simple-base-input.component.ts` | true | browser/dev/prod/ssr | contract resolution | Refer to `projects/praxis-dynamic-fields/src/lib/base/simple-base-input.component.ts`. |
| `praxis-native-date-adapter.ts` | true | browser/dev/prod/ssr | locale-aware date parsing | Refer to `projects/praxis-dynamic-fields/src/lib/utils/praxis-native-date-adapter.ts`. |

## Coverage by surface (obrigatorio)

### Coverage matrix (runtime, schema/type, editor/tooling)

| Surface | Verified | Coverage status | Evidence | Notes |
| --- | --- | --- | --- | --- |
| Runtime | `true` | Active | `projects/praxis-dynamic-fields/src/lib/components/material-datepicker/material-datepicker.metadata.ts`, `projects/praxis-dynamic-fields/src/lib/components/material-datepicker/material-datepicker.component.ts` | Core runtime flows verified via focused component specs on 2026-03-06; editor/tooling coverage remains independent. |
| Schema/Types | `true` | Active | source_of_truth + Detailed API reference | Reconcile schema/types with canonical paths during follow-up when needed. |
| Editor/Tooling | `false` | Partial | `projects/praxis-core/src/lib/metadata/field-selector-control-type.constants.ts`, `projects/praxis-dynamic-fields/src/lib/services/component-registry/component-registry.service.ts` | Selector/control-type tooling linkage verified via default selector map and registry seeding; visual editor end-to-end coverage remains not-yet-verified. |

### Runtime coverage boundaries

- Ambientes suportados: browser/dev/prod; SSR/hydration appears to be component-dependent unless explicitly verified.
- Pre-condicoes: payload JSON valido, bindings de host consistentes e dependencias descritas no source_of_truth.
- Fora de cobertura confirmada: caminhos internos, experimentais ou aliases nao enumerados formalmente.

### Editor and tooling notes

- Evidencia de tooling: selector `pdx-*` mapeado em `DEFAULT_FIELD_SELECTOR_CONTROL_TYPE_MAP` e semeado no `ComponentRegistryService`; editor visual E2E permanece not-yet-verified.
- O que esta exposto no editor visual depende da cobertura real do workspace e nao deve ser inferido como suporte runtime total.
- Campos disponiveis apenas via JSON/manual devem continuar no contrato, com rotulo explicito de cobertura parcial.
- Quando houver divergencia entre editor e runtime, manter mismatch rastreavel em secao dedicada.

## Resolution and precedence model (obrigatorio)

### Merge order

1. defaults do componente
2. contrato JSON recebido
3. overrides de host/runtime
4. normalizacoes internas

### Fallback order

contrato explicito -> aliases legados (quando suportados) -> defaults internos -> comportamento seguro

### Override points

- inputs publicos do componente
- configuracao JSON de runtime
- integracoes de host (servicos/tokens/adapters)

### Runtime normalization

Alias e defaults devem convergir para paths canonicos; onde nao houver evidencia, manter not-yet-verified de forma explicita.

### Precedence rules

Em conflito entre alias legado e path canonico, priorizar path canonico e registrar janela de migracao do legado.

## Validation and error semantics (obrigatorio)

### Validation model

| Path/Rule | Validation phase | Behavior on fail | Error code / warning | Notes |
| --- | --- | --- | --- | --- |
| canonical-paths | parse/runtime | component-defined (warn/reject/default) | not-yet-standardized | Semantica detalhada preservada na referencia tecnica por componente. |

### Invalid and unknown field handling

- Campos desconhecidos: comportamento component-defined (ignore, warn ou reject).
- Tipos invalidos: pode haver fallback, warning ou falha, conforme runtime especifico.
- Valores fora de dominio: registrar observed vs desired em Known limitations and mismatches.

### Fail-open / fail-closed behavior

| Condition | Mode | Runtime behavior | Consumer impact |
| --- | --- | --- | --- |
| invalid-or-unknown-field | component-defined | not-yet-verified | Pode gerar warning, fallback silencioso ou rejeicao; validar por componente. |

### Runtime warnings vs hard failures

| Condition | Severity | Observability | Consumer action |
| --- | --- | --- | --- |
| partial-or-declared-only-coverage | warning | logs/eventos do componente | Confirmar ligacao runtime antes de uso critico. |
| mismatch-confirmed | error-or-warning | componente/host observability | Planejar migracao e corrigir contrato/runtime. |

## Detailed API reference
### Preserved technical reference (normalized from previous revision)

### 1. Visao Geral e Quando Usar
`pdx-material-datepicker` e o campo de data orientado por JSON em `@praxisui/dynamic-fields`, baseado em `MatDatepicker`.

Use quando precisar:
- selecao de data unica com calendario Material;
- restricao por data minima/maxima;
- filtro de datas validas (`dateFilter`) e modo touch.

### 2. API do Componente (Inputs/Outputs)
| Propriedade | Tipo | Padrao | Obrigatorio | Comportamento |
| --- | --- | --- | --- | --- |
| `metadata` | `MaterialDatepickerMetadata` | - | Sim | Contrato principal do datepicker. |
| `readonlyMode` | `boolean` | `false` | Nao | Sobrescreve leitura no host. |
| `disabledMode` | `boolean` | `false` | Nao | Sobrescreve estado disabled no host. |
| `visible` | `boolean` | `true` | Nao | Controla exibicao no host. |
| `presentationMode` | `boolean` | `false` | Nao | Modo apresentacao (sem edicao). |
| `validationChange` | `ValidationErrors \| null` | - | Output | Emite estado de validacao apos `validateField()`. |

### 3. Matriz de Cobertura JSON (Completa)
#### 3.1 Campos especificos do componente
| Caminho JSON | Tipo | Status | Comportamento em runtime |
| --- | --- | --- | --- |
| `metadata.controlType` | `'datePicker'` | Ativo | Identifica contrato do componente no host. |
| `metadata.minDate` | `Date \| string` | Ativo | Converte string para `Date` e aplica limite minimo no input/calendar. |
| `metadata.maxDate` | `Date \| string` | Ativo | Converte string para `Date` e aplica limite maximo no input/calendar. |
| `metadata.startView` | `'month' \| 'year' \| 'multi-year'` | Ativo | Define visao inicial do calendario. |
| `metadata.startAt` | `Date \| string` | Ativo | Define data inicial de abertura do calendario. |
| `metadata.touchUi` | `boolean` | Ativo | Habilita modo touch do `MatDatepicker`. |
| `metadata.dateFilter` | `(date) => boolean` | Ativo | Aplica filtro customizado de datas permitidas. |
| `metadata.dateFormat` | `string` | Ativo | Define ordem numerica de exibicao quando usa `dd/MM/yyyy` ou `MM/dd/yyyy`. |
| `metadata.displayFormat` | `string` | Ativo | Define ordem numerica de exibicao quando usa `dd/MM/yyyy` ou `MM/dd/yyyy`. |
| `metadata.locale` | `string` | Ativo | Define locale do `DateAdapter` para parse e apresentacao do campo. |

Notas de runtime:
- evento `(dateChange)` chama `setValue(event.value ?? null)`.
- clear customizado limpa valor para `null` e marca controle como dirty/touched.

#### 3.2 Campos herdados compartilhados (exaustivo)
Contrato completo dos campos herdados consumidos por `SimpleBaseInput`:
- [pdx-base-input-runtime-contract.json-api.md](projects/praxis-dynamic-fields/src/lib/base/pdx-base-input-runtime-contract.json-api.md)

Resumo de composicao deste componente:
- `Ativo`: contrato de datepicker + validacao + clear.
- `Declared-only`: `dateFormat`.

### 4. Mapeamento de Comportamento
- Paginacao: nao se aplica.
- Ordenacao: nao se aplica.
- Selecao: `Date | null`.
- Eventos: `validationChange` + outputs herdados (`valueChange`, `focusChange`, `nativeBlur`, `nativeChange`).
- Renderizacao: `mat-form-field` + input com `matDatepicker`, toggle e painel de calendario.

### 5. Exemplo Minimo (JSON + Uso)
```json
{
  "componentId": "pdx-material-datepicker",
  "metadata": {
    "name": "birthDate",
    "label": "Data de nascimento",
    "controlType": "datePicker"
  }
}
```
Uso: renderiza seletor de data unico com calendario Material.

### 6. Exemplo Corporativo (JSON + Uso)
```json
{
  "componentId": "pdx-material-datepicker",
  "metadata": {
    "name": "contractStart",
    "label": "Inicio do contrato",
    "controlType": "datePicker",
    "required": true,
    "minDate": "2020-01-01",
    "maxDate": "2035-12-31",
    "startView": "year",
    "startAt": "2026-01-01",
    "touchUi": true,
    "dateFilter": "fn:isBusinessDay",
    "hint": "Selecione uma data util dentro da janela permitida."
  },
  "readonlyMode": false,
  "disabledMode": false
}
```
Uso: padrao corporativo com janela de datas e UX mobile. Em runtime atual, `dateFilter` deve ser funcao real no objeto metadata (nao string literal).

### 7. Troubleshooting e Armadilhas Comuns
1. Enviar `dateFilter` como string JSON.
Correcao: o componente espera uma funcao `(date) => boolean` no runtime.

2. Esperar qualquer padrao custom por `dateFormat`.
Correcao: o runtime suporta locale explicito e ordem numerica `dd/MM/yyyy` ou `MM/dd/yyyy`; outros padroes devem ser validados antes de uso corporativo.

3. Passar `minDate`/`maxDate` em formato invalido.
Correcao: enviar `Date` valido ou string parseavel para `new Date(...)`.

4. Campo continua editavel em tela de apresentacao.
Correcao: combine `readonlyMode`/`presentationMode` no host para travar interacao.

5. Erros de validacao nao aparecem.
Correcao: validar `validators`/matcher e estado touched/dirty do controle no host.
