+# tables_qa
+
+Testbed agresivo del modulo `data_table_cpp` (v2.0.0+). Sustituye al `tables_playground` legacy (issue 0108).
+
+Provee un panel de control QA con toggles, inyector de eventos, counters live y version selector para ejercer todas las capacidades del modulo en runtime.
+
+## Capacidades cubiertas
+
+Cada tab demuestra UNA capacidad del modulo. Toda capacidad listada en `docs/MODULES_API.md::Capability matrix consolidada` tiene su tab.
+
+| Tab | Capacidad |
+|---|---|
+| `basic` | Text default + sort + filter chips |
+| `renderers` | 1 columna por cada CellRenderer (Badge, Progress, Duration, Icon, Button, Dots, CategoricalChip, ColorScale) |
+| `buttons` | Click events: Retry, Cancel, Inspect (consumido en `events_out`) |
+| `color_rules` | ColorScale numerico + CategoricalChip configurado |
+| `dots` | Status timeline sparkline |
+| `joins` | 2 tablas + JoinStrategy Left/Inner/Right/Full toggleable |
+| `tql` | Pipeline TQL completo + Ask AI panel |
+| `drill` | Drill-down stages con breadcrumb |
+| `events` | Inyector de eventos via worker thread (RowDoubleClick, RowRightClick, ButtonClick) |
+| `compat` | Version selector + side-by-side con downgrade |
+
+## Panel QA superior
+
+Barra de control con:
+- Toggles por feature (15+ checkboxes que mutan ColumnSpec en runtime).
+- Inyector de eventos (4 botones que disparan TableEvents via worker).
+- Counters live (`data_table::internal::*` — pendiente implementar en modulo).
+- Version dropdown (2.0.0 / 1.5.0 compat / 1.4.0 compat).
+- Boton "Run --self-test" (suite headless).
+- Boton "Export golden" (regenera PNGs baseline).
+
+## Build
+
+```bash
+cd cpp && cmake --build build --target tables_qa -j
+```
+
+## Run
+
+```bash
+./cpp/build/apps/tables_qa/tables_qa
+```
+
+## Headless self-test
+
+```bash
+./cpp/build/apps/tables_qa/tables_qa --self-test
+# Exit 0 = todas las capacidades verde
+# Exit 1 = algun TableEvent no se emite o renderer crash
+```
+
+## Relacion con `tables_playground` (deprecado)
+
+`apps/primitives_gallery/playground/tables/` queda como **legacy archive** post-0108. Su `self_test.cpp` (603 checks contra logica legacy) NO se reemplaza directo — los tests aplicables a logica pura del registry ya viven en `cpp/tests/` (Catch2). Los tests aplicables a `data_table::render` viven aqui en `tables_qa --self-test`.
+
+
+## Capability growth log
+
+Una linea por bump SemVer. Bump-type segun `.claude/commands/version.md`:
+- `major`: breaking observable (CLI args, schema BBDD propia, formato wire).
+- `minor`: feature aditiva (nuevo panel, endpoint, opcion).
+- `patch`: bugfix sin cambio observable.
+
+- v0.1.0 (2026-05-18) — baseline.
