 """Data-quality chapter (CALIDAD) for AutomaticEDA.
 
 Builds the quality chapter from a ``TableProfile`` of the ``eda`` group. The
-chapter answers, in Spanish and as tables, the three things the user asked for:
+chapter implements the quality model of report 2046:
 
-1. **En qué se basa la calidad** — an intro paragraph explaining the criteria and
-   their weights (completeness, validity, consistency) before any number, plus a
-   table-level summary (global score and aggregates).
+1. **En qué se basa la calidad** — an intro paragraph explaining the two scored
+   dimensions and their weights (completitud 60%, validez 40%) plus the
+   table-level row uniqueness, BEFORE any number, and stating explicitly that
+   outliers are reported as observations and do **not** lower the score. The
+   criteria terms (calidad de datos, completitud, validez, unicidad de registro)
+   are hooked into the shared glossary as clickable jumps.
 2. **Scores por columna** — a table with, per column, the total quality score and
-   its breakdown into completeness / validity / consistency.
-3. **Problemas en español** — a second table listing, per column, the readable
-   issues in Spanish (kept separate from the type ``flags``).
+   its breakdown into completeness / validity (no consistency dimension).
+3. **Problemas de calidad** — a table listing ONLY real quality defects
+   (nulls, empty cells, values not conforming to their type/semantics).
+4. **Observaciones analíticas** — a SEPARATE table for outliers, constant
+   columns, high-cardinality ids and strong skew, with an explicit note that
+   these do not affect the score.
 
-The breakdown and the issues are NOT recomputed here: they come from the registry
-function ``column_quality_score`` (group ``eda``), which already derives
-``{score, completeness, validity, consistency, issues}`` from the ColumnProfile.
-This chapter is render-only — it consumes that function and lays the result out
-as model blocks; the renderers paginate tables (splitting by rows, repeating the
-header) and wrap long cells so nothing is ever cut.

+`summarize_table_duckdb` / `profile_table`) y necesites un numero 0-100 por
+columna para ordenar/priorizar limpieza de datos, pintar semaforos de calidad,
+o decidir que columnas descartar antes de modelar. Separa los **defectos de
+calidad reales** (`issues`: nulos, vacios, valores que no parsean a su tipo) de
+las **observaciones analiticas** (`observations`: outliers, columnas constantes,
+ids), que se reportan pero no penalizan. Es la capa de scoring sobre el

-## Notas
+## Gotchas
 
-Funcion pura, sin I/O ni dependencias externas, no muta `col`. Lee todas las
-claves con `.get(...)` y tolera que vengan en `None` (un ColumnProfile recien
-salido de `summarize_table_duckdb` trae muchas claves a `None`), por lo que
-nunca falla por claves ausentes — un `{}` produce un resultado bien definido.
+Funcion pura, sin I/O, no muta `col`. Aun asi conviene saber:
 
-Pesos del score: completeness 0.5, validity 0.3, consistency 0.2.
+- **Los outliers NO bajan el score.** Un valor extremo puede ser real y correcto
+  (un cliente que compra mucho); detectar atipicos es analisis de la
+  distribucion, no un juicio de correccion. Salen en `observations`, no en
+  `issues`. Mismo trato para columnas constantes e identificadores de alta
+  cardinalidad: son observaciones, no defectos.
+- **`validity` puede ser `None`** (no aplicable): texto libre sin `semantic_type`
+  ni `validity_rate`, o columna 100% nula. En ese caso el score se renormaliza a
+  solo `completeness` (la columna no se premia ni castiga por algo no medible).
+- **`outlier_pct` se interpreta en escala 0-100** (la que emite
+  `describe_numeric`, z-score>3). Pasar una fraccion 0-1 produce un texto de
+  observacion con el % equivocado, pero NUNCA afecta al score.
+- **`validity_rate` lo puebla `profile_table`** al promocionar una columna de
+  texto a numero/fecha (fraccion que parsea). Si no esta presente y el tipo es
+  nativo numerico/fecha/bool, `validity = 1.0`.
+- Sin doble conteo: la falta de datos cuenta solo en `completeness` (el antiguo
+  castigo de `mostly_null` sobre `validity` se elimino).
 
-- **completeness** = `1 - null_pct` (None -> 0 nulls -> 1.0).
-- **validity**: parte de 1.0 y penaliza `min(outlier_pct, 0.3)` en columnas
-  numericas, `0.5 * (1 - match_rate)` si hay `semantic_type` declarado con
-  `match_rate` bajo disponible, y multiplica por 0.5 si el flag `mostly_null`
-  esta presente.
-- **consistency**: 1.0 salvo flag `constant` (-> 0.3, columna poco informativa)
-  o texto con `unique_pct > 0.9` (-> 0.6, posible id de alta cardinalidad).
+## Capability growth log
+
+- v2.0.0 (2026-06-30) — nueva formula de calidad (report 2046): pesos 60/40
+  (completeness/validity) con renormalizacion por aplicabilidad; se elimina la
+  dimension `consistency`-como-informatividad y el doble castigo de
+  `mostly_null`; los outliers/constantes/ids salen del score a `observations`;
+  validity mide conformidad real (parse rate / match rate / tipo nativo). Salida
+  ampliada con `dimensions`, `applicable` y `observations`.
+- v1.0.0 — version inicial: pesos 50/30/20 (completeness/validity/consistency),
+  los outliers penalizaban validity (con bug de escala) y consistency penalizaba
+  informatividad.

@@ -64,6 +64,7 @@ else:
 - **`distinct_count` exacto para tablas <=200k filas, aproximado+capado por encima**: `SUMMARIZE` usa HyperLogLog (`approx_unique`), que SOBREESTIMA y en tablas pequenas puede reportar mas distintos que filas (inflando `unique_pct` por encima de 1.0 y disparando flags `possible_id` falsos). Por eso, para `n_rows <= 200000` la funcion calcula `COUNT(DISTINCT)` EXACTO en una sola query combinada (barata) y usa ese valor. Para tablas mas grandes mantiene `approx_unique` pero lo CAPA a `n_rows` (`distinct_count = min(approx_unique, n_rows)`). En ambos casos `unique_pct = min(distinct_count / n_rows, 1.0)`, asi que `distinct_count` nunca supera las filas ni `unique_pct` pasa de 1.0. Los flags `possible_id` / `high_cardinality` derivan de ese `distinct_count` ya corregido (exacto y fiable por debajo de 200k filas; aproximado y conservador por encima).
 - **`SUMMARIZE` NO da skew, kurtosis ni histograma**, ni percentiles finos (p1/p5/p95/p99), moda, outliers, correlaciones, key_candidates ni quality_score. Esas claves quedan en `None`/`[]` a proposito: las rellena otra funcion del grupo `eda` sobre una muestra. El sub-dict `numeric` solo trae min, max, mean, std, p25, p50, p75.
 - **`SUMMARIZE.count` es el total de filas, no el no-nulo**: la funcion deriva el `count` no-nulo del ColumnProfile como `n_rows - null_count` (con `null_count` redondeado de `null_percentage`).
+- **`duplicate_rows`/`duplicate_pct` se pueblan push-down** (desde v1.1.0) con `count(*)` sobre `SELECT DISTINCT *` (sin traer filas a RAM): `duplicate_rows = n_rows - filas_distintas`, `duplicate_pct` en fraccion 0-1. Habilitan la dimension de unicidad de registro del score de dataset (`profile_table` paso 6). Si la tabla tiene tipos no comparables con `DISTINCT` (BLOB/LIST/MAP) la query degrada y ambas vuelven a `None` (renormaliza el score a solo `cell_quality`).
 - **min/max/avg/std/q25/q50/q75 vienen como strings** desde DuckDB; se convierten a float (None si la columna no es numerica).
 - **Requiere DuckDB 1.5.2** (columnas de `SUMMARIZE` validadas con esa version: column_name, column_type, min, max, approx_unique, avg, std, q25, q50, q75, count, null_percentage).
 - **El identificador de tabla se interpola** (no parametrizable en `SUMMARIZE`): por eso se valida contra `^[A-Za-z_][A-Za-z0-9_]*$` antes de citarlo. Un nombre invalido (p.ej. con `;` o espacios) devuelve `{status:'error'}` sin tocar la base.
