 cuando una tabla larga se parte y repite cabecera (el índice de fila es lógico, no por

+### 11.4 Calidad de render global: DPI alto, tabla ancha → imagen, figura al lado, índice clicable
+
+Cuatro capacidades transversales del motor, **todas automáticas salvo `layout`** (que un
+capítulo activa explícitamente). Aplican a PDF y PPTX salvo donde se indique.
+
+**(a) DPI alto (automático).** Toda figura/imagen embebida se rasteriza a **220 dpi**
+(constante `_RASTER_DPI` en ambos renderers; en PDF se aplica también al `savefig` de la
+página, porque matplotlib re-rasteriza cada `imshow` al escribir la página). Objetivo:
+ampliar en el móvil y leer detalle (ejes, celdas) sin pixelar. El texto sigue siendo
+vectorial y seleccionable. No hay nada que hacer en los capítulos.
+
+**(b) Tabla ancha → imagen de alta resolución (automático).** Cuando un `DataTable` tiene
+**demasiadas columnas para ser legible como texto** en el ancho útil (criterio
+`_table_fits_as_text`: ancho mínimo legible por columna × nº de columnas > ancho útil; en
+la práctica salta sobre tablas tipo `df.head` con muchas columnas), en vez de comprimir las
+columnas hasta hacerlas ilegibles, la tabla se dibuja **entera como una imagen de alta
+resolución** (función `render_table_as_figure_py_datascience`: cabecera sombreada + zebra)
+escalada para caber completa, de modo que el lector hace **zoom** y la lee sin perder datos.
+Si la tabla **sí cabe**, se mantiene como texto seleccionable (PDF) / tabla nativa (PPTX).
+Las `KVTable` (2 columnas) caben siempre y se quedan como texto. No hay nada que hacer en
+los capítulos.
+
+**(c) Figura al lado de la tabla — `Group(layout="side_by_side")`.** Hint de layout que un
+capítulo activa para que su **tabla quede a la izquierda y su figura a la derecha** en la
+misma diapositiva, en lugar de apiladas:
+
+```python
+model.Group(
+    layout="side_by_side",
+    blocks=[
+        model.Heading(text=str(name), level=2),       # va a ancho completo arriba
+        model.DataTable(header=..., rows=...),         # columna IZQUIERDA (~55%)
+        model.Figure(make=_grafico_perezoso(...)),     # columna DERECHA (~45%)
+        model.Markdown(text="explicación…"),           # va a ancho completo abajo
+    ])
+```
+
+Contrato exacto del campo:
+
+| Campo | Valor | Efecto |
+|---|---|---|
+| `layout` | `"stack"` (por defecto) | comportamiento histórico: apilado vertical (keep-together). |
+| `layout` | `"side_by_side"` | **PPTX**: la tabla (rasterizada a imagen) ocupa la columna izquierda (~55% del ancho útil) y la figura la derecha (~45%); cualquier otro bloque (heading, markdown) va a ancho completo arriba/abajo. Si no hay un par tabla+figura, o no caben lado a lado en una slide, **cae automáticamente a apilado**. **PDF**: se trata **igual que `stack`** (el ancho A5 móvil no admite dos columnas legibles). Valores desconocidos degradan a `"stack"`. |
+
+Es **retrocompatible**: un `Group` sin `layout` (o `layout="stack"`) se comporta exactamente
+como antes. El capítulo `cat_distr` es el consumidor previsto (gráfico a la derecha de la
+tabla de categorías en PPT); este motor solo provee el soporte.
+
+**(d) Índice clicable en la portada — `TocEntry`.** La portada emite un `Heading("Índice")`
+seguido de un `TocEntry(label, target_id)` por capítulo. El renderer registra la
+página/slide de inicio de **cada** capítulo (indexado por `id` **y** por `title`) y cablea
+cada `TocEntry` como un salto real a ese inicio: en **PDF** vía
+`add_pdf_internal_links_py_datascience` (link GOTO de PyMuPDF), en **PPTX** vía
+`pptx_link_run_to_slide_py_datascience` (salto a slide nativo). Como la portada solo conoce
+los **títulos** de los capítulos, el `target_id` se hace coincidir contra el `title` (o el
+`id`) de destino. Si un destino no resuelve, la entrada se muestra igualmente como texto
+(en color de enlace), nunca se corta. Es el mismo mecanismo que los términos clicables del
+glosario (§11.1), reutilizado en sentido portada → capítulo.

+  * Wide table → image: a table too wide to be legible as text (e.g. a 19-column

+  * Backward compatibility: a Group without ``layout`` defaults to ``"stack"`` and

+## Ejemplo

+from categorical_top_bar_figure import categorical_top_bar_figure
+
+# `top` es la salida del bloque "top" de summarize_categorical (ya ordenado desc).
+top = [
+    {"value": "rojo", "count": 40, "pct": 0.40},
+    {"value": "azul", "count": 30, "pct": 0.30},
+    {"value": "verde", "count": 20, "pct": 0.20},
+    {"value": "amarillo", "count": 5, "pct": 0.05},
+]
+
+fig = categorical_top_bar_figure(
+    top,
+    n_distinct=12,            # 12 categorías distintas en total
+    title="color_producto",
+    top_k=6,                  # hasta 6 barras explícitas
+    n_rows=100,               # "Otros" = 100 - 95 = 5, sobre 8 categorías agregadas
+)
+
+# El renderer del informe lo rasteriza; aquí solo persistimos para inspección.
+fig.savefig("/tmp/barras_color.png")
+```
+
+## Cuando usarla
+
+Úsala dentro de un informe EDA cuando quieras comparar **magnitudes** de las
+categorías dominantes de una columna categórica: qué categoría manda y por
+cuánto frente a las siguientes. Pásale directamente el bloque `top` de
+`summarize_categorical` (ya ordenado de mayor a menor) más `n_distinct` para que
+la barra "Otros" indique cuántas categorías quedan agrupadas. Es el clon "de
+barras" del donut `categorical_top_pie_figure` con **contrato de entrada
+idéntico**: puedes intercambiar una por otra sin tocar el caller. Elige barras
+cuando importe comparar tamaños exactos; el donut cuando importe la proporción
+del total.
+
+## Gotchas
+
+- **Impura por matplotlib.** Toca la maquinaria de render. Usa el backend `Agg`
+  y la API orientada a objetos `Figure`/`add_subplot` — NUNCA `pyplot.*` aquí,
+  para no tocar el estado global ni filtrar figuras entre llamadas. `pyplot` NO
+  es thread-safe; esta función evita ese riesgo construyendo el `Figure`
+  directamente, así que es segura de llamar en bucle desde el renderer.
+- **El caller cierra la figura.** La función devuelve el `Figure` pero no lo
+  muestra ni lo guarda. Quien la consume debe rasterizarla y luego liberarla
+  (`fig.clf()` / `matplotlib.pyplot.close(fig)` si se usó pyplot en el caller)
+  para no acumular memoria en lotes grandes de columnas.
+- **`barh` dibuja de abajo arriba.** La categoría más frecuente va arriba porque
+  el orden de display se invierte antes de plotear; la barra "Otros" queda
+  siempre al fondo. No reordenes `top` esperando otro layout: la función asume
+  que ya viene ordenado desc por count.
+- **Magnitud exacta de "Otros" solo con `n_rows`.** Sin `n_rows`, la barra
+  "Otros" se calcula con el overflow presente en `top`; si `top` ya viene
+  recortado a `top_k` por el productor, no habrá "Otros" aunque existan más
+  categorías. Pasa `n_rows` (total de filas del dataset) para una barra correcta
+  respecto al total real.
+- **Defensiva, nunca lanza.** `top=[]`, `value=None`, `count=None` o counts no
+  numéricos se manejan sin error: en el peor caso devuelve una `Figure` con
+  "sin datos categóricos", y cualquier excepción inesperada cae a una `Figure`
+  con el texto del error. No envuelvas la llamada en try/except por miedo a un
+  raise — no lo hay.

+# Luego perfila la carpeta/base con el grupo eda:
+#   fn run profile_database /tmp/eda_folder
+```
+
+## Cuando usarla
+
+- Cuando necesites un fixture REPRODUCIBLE multi-tabla para evaluar el EDA de carpeta/base (`profile_database`, join graph, capitulo de relaciones inter-tabla) con relaciones FK reales y detectables.
+- Cuando escribas tests de la deteccion de claves foraneas por containment: orders y reviews referencian customer_id contenido al 100% en customers (inclusion 1.0 >= min_inclusion 0.9).
+- Como contraparte multi-tabla de `generate_synthetic_eda_table` (que cubre el EDA de UNA tabla).
+
+## Gotchas
+
+- **Impura**: escribe 3 CSV a disco (`mkdir -p` de la carpeta). Sobrescribe los CSV existentes con el mismo nombre.
+- **Requiere `faker`, `numpy` y `pandas`** en el venv. Sin `faker` devuelve `{status:'error'}` (no lanza).
+- **El containment depende del orden**: customers se genera PRIMERO y orders/reviews muestrean sus `customer_id`. Si se invierte el orden, la FK deja de estar contenida y el detector no la encuentra.
+- **`signup_date`/`ts` se escriben como texto ISO en el CSV** (`YYYY-MM-DD` / `YYYY-MM-DD HH:MM:SS`): es CSV, todo es texto; el profiler los promociona a datetime al leerlos.
+- **Determinismo dependiente del orden de llamadas**: se siembra `Faker.seed(seed)` + `np.random.default_rng(seed)` al inicio; mismo seed -> CSVs identicos byte a byte.
+- **Reutiliza helpers privados** de `generate_synthetic_eda_table` (`_make_fakers`, `_make_latlon`, `_make_reviews`, `_amount_with_outliers`): no romper esas firmas sin actualizar esta funcion.
+
+## Notas
+
+Estructura generada:
+
+| Archivo | PK | FK | Columnas clave |
+|---|---|---|---|
+| customers.csv | customer_id (uuid) | — | name, country, signup_date, latitude, longitude, email |
+| orders.csv | order_id (uuid) | customer_id -> customers | amount (lognormal + outliers), category, ts |
+| reviews.csv | review_id (uuid) | customer_id -> customers | review_text (multi-idioma, mediana palabras>=20), rating (1..5) |
+
+orders tiene ~2x filas que customers y reviews ~1x. Todos los `customer_id` de orders
+y reviews estan contenidos en customers (containment ⊆), por lo que la deteccion FK por
+inclusion descubre las dos relaciones declaradas en `expected_relations`.

+## Ejemplo
+
+```bash
+# Genera /tmp/x.duckdb con la tabla `synthetic` (2000 filas, seed 42)
+fn run generate_synthetic_eda_table /tmp/x.duckdb synthetic 2000 42
+```
+
+```python
+import sys, os
+sys.path.insert(0, os.path.join("python", "functions"))
+from datascience import generate_synthetic_eda_table
+
+res = generate_synthetic_eda_table("/tmp/x.duckdb", "synthetic", n_rows=2000, seed=42)
+# res == {"status":"ok", "db_path":"/tmp/x.duckdb", "table":"synthetic",
+#         "n_rows":2000, "columns":[...19...], "seed":42}
+# Luego perfilala con el grupo eda:
+#   fn run profile_table /tmp/x.duckdb synthetic
+```
+
+## Cuando usarla
+
+- Cuando necesites un dataset de prueba REPRODUCIBLE para evaluar el motor AutomaticEDA de punta a punta: su contenido dispara, a proposito, num_distr, cat_distr, text_distr, correlacion, missingness (MCAR/MAR), modelos (PCA/KMeans/outliers), timeseries, geospatial, calidad, agregacion y los detectores semanticos / PII (`infer_semantic_type`).
+- Cuando escribas tests de capitulos del EDA y quieras una tabla con una columna que active CADA detector sin montar datos a mano.
+- Cuando quieras un fixture determinista (mismo seed -> misma tabla) para comparar el render del EDA entre versiones.
+
+## Gotchas
+
+- **Impura**: escribe a disco (crea/reutiliza el archivo DuckDB). Reemplaza la tabla destino con `CREATE OR REPLACE`.
+- **Requiere `faker`, `duckdb`, `numpy` y `pandas`** instalados en el venv. Sin `faker` la generacion devuelve `{status:'error'}` (no lanza).
+- **`signup_date` queda como TIMESTAMP/DATE en DuckDB** (se construye con `datetime64[ns]`), NO VARCHAR — condicion para que `detect_time_column` la elija y se active el capitulo timeseries. Si fuese VARCHAR, el detector de fecha fallaria.
+- **El texto de `review` debe superar el gate de text_distr**: media de caracteres >= 50 y mediana de palabras >= 20. Por eso cada review concatena dos parrafos Faker (~50 palabras de mediana); no reducir el numero de frases o el capitulo text_distr no activa.
+- **Determinismo dependiente del orden de llamadas**: se siembra `Faker.seed(seed)` + `np.random.default_rng(seed)` al inicio; cambiar el orden de las extracciones cambia la salida aunque el seed sea el mismo.
+- **PII real-istica**: `email`/`iban`/`phone`/`customer_id` matchean los regex de `infer_semantic_type` (email/iban/phone_intl/uuid) al 100%; son datos sinteticos de Faker, no personas reales.

+| tenure_months, engagement_quad | num continua | relacion NO LINEAL (cuadratica) |
+| amount, n_purchases | num + outliers | num_distr / outliers (cola pesada + extremos inyectados) |
+| country (12), category (6), plan (3 desbalanceado) | categorica | cat_distr / agregacion (entropia baja en plan) |
+| review | texto libre multi-idioma | text_distr (len_mean>=50, mediana palabras>=20) + duplicados exactos |
+| signup_date | DATE/TIMESTAMP | timeseries |
+| latitude, longitude | num [-90,90]/[-180,180] | geospatial (detect_latlon_columns) |
+| customer_id, email, iban, phone | texto | semantic_type uuid/email/iban/phone_intl (PII) |
+| income+spending (co-nulos 12%), risk_score (nulo si plan=alta), review (8%) | nulos con patron | missingness MCAR/MAR |

+
+```python
+from datascience import load_bq_table_to_duckdb
+
+# FULL por defecto: trae TODAS las filas de la vista (3,8M) a DuckDB.
+r = load_bq_table_to_duckdb(
+    "autingo-159109.customer_marts.customer_profile",
+    "/tmp/eda_bq.duckdb",
+    pseudonymize_cols=["document_number", "full_name", "email", "phone"],
+)
+print(r["table"], r["n_rows_fetched"], "de", r["n_rows_source"], "sampled=", r["sampled"])
+
+# Muestreo opt-in: ~5 % de las filas.
+r = load_bq_table_to_duckdb(
+    "autingo-159109.customer_marts.customer_profile",
+    "/tmp/eda_bq_sample.duckdb",
+    sample_frac=0.05,
+    pseudonymize_cols=["document_number", "full_name", "email", "phone"],
+)
+```
+
+## Cuando usarla
+
+- Antes de perfilar una tabla/vista de BigQuery con el grupo `eda` (que solo habla DuckDB/PostgreSQL): trae el origen COMPLETO a DuckDB local (o una muestra con `sample_frac`) con seudonimización PII.
+- Cuando necesites un puente único BigQuery -> DuckDB local -> grupo `eda` sin escribir el bridge inline cada vez.
+- Cuando quieras que un EDA sobre datos de negocio conserve valor analítico (cardinalidad, nulos, distribución) sin incrustar datos personales reales.
+
+## Gotchas
+
+- **Impura**: hace I/O de red (BigQuery) + escritura a disco (DuckDB). Requiere ADC configurado (`gcloud auth application-default login`).
+- **403 USER_PROJECT_DENIED**: se evita aplicando `creds.with_quota_project(None)` cuando el ADC arrastra un quota project ajeno (memoria `bq_direct_quota_project`).
+- **TABLESAMPLE no funciona en vistas**: el muestreo (opt-in, `sample_frac`) usa `WHERE rand() < frac` (aplicable a tablas y vistas). `max_rows` es un `LIMIT` como tope duro opcional.
+- **FULL por defecto**: `sample_frac=None` trae TODAS las filas. Trae el resultado a RAM como DataFrame de pandas antes de materializar en DuckDB, así que una tabla de muchos millones × muchas columnas puede consumir varios GB. Para tablas enormes que no quepan, pasa `sample_frac` (muestra) o `max_rows` (tope). El fetch usa el BigQuery Storage Read API (Arrow) cuando `google-cloud-bigquery-storage` + `pyarrow` están disponibles — mucho más rápido que REST para millones de filas; si no, cae al conversor REST automáticamente.
+- **La seudonimización es un hash unidireccional** (SHA-1 truncado a 12 hex): no es reversible, correcto para EDA. Preserva nulos, cardinalidad y patrón de faltantes, pero NO permite recuperar el valor original.
+- **dict-no-throw**: nunca lanza excepción; ante cualquier fallo (FQN inválido, auth, query) devuelve `{status:'error', error:str}`.
+
+## Notas
+
+Adaptador del grupo de capacidad `eda`: el resto de funciones del grupo perfilan
+DuckDB/PostgreSQL, pero no hablan BigQuery de forma nativa. Esta función cubre ese
+hueco materializando una sola tabla DuckDB desde el DataFrame resultante de la
+query BigQuery. El nombre de tabla destino se sanea (`^[A-Za-z_][A-Za-z0-9_]*$`)
+antes de citarlo en el `CREATE OR REPLACE TABLE`.
+
+## Capability growth log
+
+- v1.1.0 (2026-07-01) — FULL pasa a ser el DEFAULT: se sustituye `max_rows=300000, sample=True` por `sample_frac=None` (None = todas las filas) + `max_rows=0` (tope duro opcional). El muestreo es opt-in explícito. Fetch acelerado via BigQuery Storage Read API (Arrow) con fallback REST. Preferencia estándar del usuario: los EDA se corren sobre el total salvo que se pida lo contrario.

+
+# Tabla que no cabe como texto en la slide -> se rasteriza y se lee con zoom.
+header = ["columna", "n_nulos", "%_nulos", "distintos", "tipo", "ejemplo"]

+    ["ingresos", 12, "1.2%", 980, "float64", "2345.67"],

+]
+
+fig = render_table_as_figure(
+    header,
+    rows,
+    title="Resumen de columnas",
+    note="rasteriza a dpi=220 y haz zoom en el móvil",

+# El renderer del informe lo rasteriza a alta resolución; aquí lo persistimos.

+
+## Cuando usarla
+
+Úsala en un informe EDA cuando una tabla **no cabe como texto** en una página o
+slide y prefieres una imagen nítida que el lector pueda ampliar en el móvil para
+leerla entera (perfiles de columnas, matrices de conteo, tablas de frecuencias
+con muchas filas o columnas anchas). Pásale la cabecera y las filas tal cual (los
+valores se `str()`-ean por ti) más un `title`/`note` opcionales; el llamante la
+rasteriza a `dpi=220` con `bbox_inches='tight'`. Es la pareja "tabla-como-imagen"
+de los gráficos `build_boxplots_figure` / `categorical_top_pie_figure`: misma
+paleta y mismo contrato (Agg, sin `pyplot`, el caller cierra la figura).
+
+## Gotchas
+
+- **Impura por matplotlib.** Toca la maquinaria de render. Usa el backend `Agg`
+  y la API orientada a objetos `Figure`/`add_subplot` — NUNCA `pyplot.*` aquí,
+  para no tocar el estado global ni filtrar figuras entre llamadas. `pyplot` NO
+  es thread-safe; esta función construye el `Figure` directamente, así que es
+  segura de llamar en bucle desde el renderer.
+- **El caller cierra la figura.** Devuelve el `Figure` pero no lo muestra ni lo
+  guarda. Quien la consume debe rasterizarla y luego liberarla
+  (`matplotlib.pyplot.close(fig)`) para no acumular memoria en lotes grandes.
+- **Pensada para rasterizar a DPI alto.** El `figsize` es proporcional al
+  contenido pero la legibilidad real viene del DPI: rasteriza con `dpi=220` y
+  `bbox_inches='tight'`. Una tabla con muchísimas filas crece en alto (capado a
+  ~60") — para miles de filas, parte la tabla o resume antes de pasarla.
+- **Truncación de celda visible.** Cada celda se recorta a `max_cell_chars`
+  (default 40) con `…` final y los saltos de línea/tabs se colapsan a espacios,
+  para que ninguna celda desborde a otras filas. Sube `max_cell_chars` si
+  necesitas ver el valor completo (a costa de ancho).
+- **Defensiva, nunca lanza.** `header`/`rows` vacíos o `None`, filas escalares,
+  filas de distinta longitud o cualquier error interno se manejan sin propagar:
+  en el peor caso devuelve una `Figure` placeholder con "(tabla no disponible)".
+  No envuelvas la llamada en try/except por miedo a un raise — no lo hay.

+    run_models=True,

+print(r["load"]["n_rows_fetched"], "filas perfiladas, sampled=", r["load"]["sampled"])
+print(r["aeda_pdf_path"]); print(r["aeda_pptx_path"]); print(r["report_md_path"])
+
+# Muestreo opt-in: EDA sobre ~5 % de las filas (tabla enorme / iteracion rapida).
+r = profile_bq_table(
+    "autingo-159109.customer_marts.customer_profile",

+    pseudonymize_cols=["document_number", "full_name", "email", "phone", "postal_code", "salesforce_customer_id"],
+)
+```
+
+## Cuando usarla
+
+Cuando pidan un EDA de una tabla o vista de BigQuery ("hazme un EDA de esta
+tabla BigQuery"). Es el adaptador BigQuery del grupo de capacidad `eda` por
+composicion: trae el origen COMPLETO (todas las filas, por defecto) a un DuckDB
+local y delega todo el perfilado y render en `profile_table`, sin adaptador
+BigQuery nativo ni logica de EDA duplicada. Usala como primer paso al recibir un
+dataset BigQuery desconocido, antes de modelar o limpiar, o para auditar la
+calidad de una vista ya productiva. Para iteracion rapida o tablas que no quepan
+en RAM, pasa `sample_frac` (muestreo opt-in).
+
+## Gotchas
+
+- Impura: requiere ADC de BigQuery configurado (Application Default Credentials)
+  para que `load_bq_table_to_duckdb` autentique contra el proyecto.
+- FULL por defecto: `sample_frac=None` perfila TODAS las filas del origen. Una
+  vista de millones de filas se trae entera a RAM (varios GB posibles) antes de
+  materializar en DuckDB; el fetch usa el BigQuery Storage Read API (Arrow) cuando
+  esta disponible, mucho mas rapido que REST. Para acotar coste/memoria, pasa
+  `sample_frac` in (0,1) (muestreo opt-in) o `max_rows` (tope duro). Si por limite
+  de recursos no cabe el total, dilo explicito con el maximo que si se cargo.
+- Seudonimiza PII con `pseudonymize_cols` para cumplir LOPDGDD/RGPD ANTES de
+  escribir a disco: nombres, DNI/NIE, email, telefono, direccion, IDs de cliente,
+  etc. Se hashean preservando nulos y cardinalidad. Sin seudonimizar, la muestra
+  materializada (DuckDB + reports) contiene datos personales reales [POL-MMNSEG-001-1.0].
+- El DuckDB temporal se borra al terminar salvo `keep_duckdb=True` (pasalo para
+  seguir explorando la muestra desde un notebook Jupyter). Si pasas `duckdb_path`
+  explicito, la ruta se respeta y solo se conserva con `keep_duckdb=True`.
+- Escribe reports a `report_dir` (default 'reports', artefacto local gitignored):
+  Markdown + JSON sidecar + PDF A5 movil + PPTX 16:9 del informe AutomaticEDA.
+- `run_llm=True` gasta tokens (haiku) pero solo envia el perfil agregado, nunca
+  filas crudas ni datos personales.
+
+## Capability growth log
+
+- v1.1.0 (2026-07-01) — FULL pasa a ser el DEFAULT del pipeline: se sustituye `max_rows=300000, sample=True` por `sample_frac=None` (None = perfila todas las filas) + `max_rows=0` (tope duro opcional). El muestreo es opt-in explicito (`sample_frac`). Alinea con la preferencia estandar del usuario: los EDA se corren sobre el total salvo que se pida lo contrario. Hereda el fetch acelerado (Arrow/bqstorage) de `load_bq_table_to_duckdb` v1.1.0.
