egutierrez d317900eea feat(cpp/core): app framework UI (settings, menubar, layouts)
5 primitivas que componen el chrome de una app fn_ui completa:

- app_settings_cpp_core         (function, impure)  ventana flotante de
  settings globales (Display + Typography + secciones extra registrables) con
  persistencia automatica en app_settings.ini junto al ejecutable.
- app_menubar_cpp_core          (component, pure)   MainMenuBar unificada
  con menu View (toggles de paneles) y Layouts. Punto de entrada de la
  menubar de cualquier app fn_ui.
- layouts_menu_cpp_core         (component, pure)   menu para guardar/aplicar/
  borrar/reset layouts de ImGui via callbacks (no I/O propio).
- panel_menu_cpp_core           (component, pure)   menu checkable para
  abrir/cerrar paneles, composable dentro de la MainMenuBar.
- layout_storage_sqlite_cpp_core (function, impure) primitivas CRUD de bajo
  nivel para persistir blobs INI de ImGui en sqlite (ui_layouts table).

Permiten que apps como shaders_lab y registry_dashboard ofrezcan: panel
toggles, layouts persistentes en BD, ventana de settings con preview en
vivo. Todas usan tokens_cpp_core para el styling.

egutierrez da6a8b5e59 feat(cpp/core): primitivas UI estilo Mantine
Anade 9 primitivas reutilizables al registry C++ que replican el comportamiento
de los componentes correspondientes de @fn_library / Mantine v9, todas
estilizadas con tokens_cpp_core (colores Mantine dark + indigo):

- button_cpp_core         (component, pure)  variantes primary/secondary/subtle/danger + sm/md/lg
- icon_button_cpp_core    (component, pure)  cuadrado 28x28 con glyph centrado + tooltip
- toolbar_cpp_core        (component, pure)  grupo horizontal de acciones con separadores
- modal_dialog_cpp_core   (component, pure)  popup modal centrada + close con Escape
- text_input_cpp_core     (component, impure) InputText con label muted + placeholder
- select_cpp_core         (component, impure) dropdown con label + opcion '(none)' opcional
- toast_cpp_core          (component, impure) notificaciones efimeras + inbox con badge
- tree_view_cpp_core      (component, impure) jerarquia low-level con tree_node_clicked helper
- process_runner_cpp_core (component, impure) tarea en std::thread + spinner inline

Cada primitiva tiene su .md con frontmatter completo (params/output) y se
indexa via fn index. Son la base del primitives_gallery y de cualquier
app fn_ui futura.

egutierrez 5d5b1d3fea feat(cpp/core): icon_font + icons_tabler
icon_font_cpp_core (impure): carga Karla-Regular como texto vectorial y
mergea Tabler Icons al mismo tamano en el atlas de ImGui. Tras el call,
los TI_* renderizan inline con el texto.

icons_tabler.h: header con macros TI_<NAME> que apuntan a los codepoints
del set Tabler (UTF-8 escapado). Generado a partir del CSS del vendor con
cpp/vendor/tabler-icons/gen_header.py — re-ejecutable si se actualiza el
set sin tocar a mano los ~5500 codepoints.

Justifica la regla cpp_icons.md: todas las apps C++ usan TI_* en lugar de
emoji o hex inline.

egutierrez bae4f45268 chore(cpp/vendor): vendor Tabler Icons v3.41.1 (TTF + generador)
Vendorea el set de iconos Tabler (~5500 iconos, MIT) para usar en apps
ImGui via icon_font_cpp_core. Incluye:

- tabler-icons.ttf       — atlas TTF para mergear en ImGui
- tabler-icons.css       — referencia de codepoints (no se compila)
- gen_header.py          — script que regenera cpp/functions/core/icons_tabler.h
                           con macros TI_<NAME> a partir del CSS
- LICENSE / README.md    — atribucion MIT

Versionar el TTF (~700 KB) evita depender de descargas en build. Las apps
usan TI_* en strings y el atlas se carga con icon_font_cpp_core::load().

egutierrez b093c898a8 docs(issues): marcar 0025 y 0026 como completados + WIP master
Wave 1 de parallel-fix-issues integrada a master:
- 0025: text_editor_cpp_core + file_watcher_cpp_core
- 0026: gl_texture_load_cpp_gfx (vendor: stb_image v2.30)

Ademas se commitea WIP previo de master que estaba sin commitear (cambios
en shaders_lab, dag_*, framework, tokens, kpi_card, gl_loader.md, etc.)
para dejar HEAD buildable.

Notas:
- Algunos deps del gallery (button.cpp, toolbar.cpp, modal_dialog.cpp...)
  siguen UNTRACKED — gating con FN_BUILD_GALLERY=ON (default OFF) para
  que master build (sin flag) no los necesite.
- Build OK con y sin flag. fn index registra 904 functions.

egutierrez d3d5af51f2 feat(primitives_gallery): wire gl_texture_load demo
Tras integrar 0025 (que trajo la app entera) y 0026 (que solo añadio
demos_gl_texture.cpp + assets/sample.png + cpp/functions/gfx/gl_texture_load.*),
falta wire-up de la entrada nueva en los archivos compartidos del gallery.

- demos.h: declarar gallery::demo_gl_texture()
- main.cpp: entrada en k_demos[] con id "gl_texture", category "Gfx"
- CMakeLists.txt: añadir demos_gl_texture.cpp, gl_texture_load.cpp,
  stb_image_impl.cpp, e include dir vendor/stb

egutierrez 087412d73a feat(primitives_gallery): wire text_editor + file_watcher demo
- demos_text_editor.cpp: split horizontal con editor GLSL precargado a la
  izquierda (boton Save to /tmp/fn_demo.glsl + dirty indicator) y panel de
  eventos a la derecha (path, active flag, lista scrollable, boton clear).
  Watcher activo sobre /tmp/fn_demo.glsl; reintenta el add() tras el primer
  Save si el archivo no existia al iniciar.
- demos.h: declaracion de gallery::demo_text_editor()
- main.cpp: entry "text_editor"/"text_editor + watcher" en categoria Core
- CMakeLists.txt: anade demos_text_editor.cpp + sources de text_editor,
  file_watcher y vendor TextEditor.cpp + include path de imgui_text_edit

Nota: la primitives_gallery NO se construye en este branch (sus deps —
button.cpp, toolbar.cpp, etc. — son untracked en master). El subdirectorio
se anade pero protegido por FN_BUILD_GALLERY=OFF para no romper builds.

egutierrez 61a238b3fd test(cpp): add text_editor_smoke build gate for issue 0025
App minima (no abre ventana ImGui) que crea/settea/lee text_editor y registra
un watch sobre /tmp/fn_smoke_test.txt para confirmar que TextEditor.cpp del
vendor + text_editor.cpp + file_watcher.cpp enlazan correctamente. Activada
por defecto si la carpeta existe (no requiere la primitives_gallery).

Tambien anade flag FN_BUILD_GALLERY (OFF default) para no romper el build
cuando la primitives_gallery no esta presente — sus deps (button.cpp,
toolbar.cpp...) son sources untracked en algunas branches.

egutierrez 07a653d97d feat(cpp/core): add file_watcher_cpp_core (inotify Linux / RDCW Win)
Watcher de archivos no bloqueante con backend nativo por plataforma:

- Linux: inotify_init1(IN_NONBLOCK | IN_CLOEXEC), inotify_add_watch con
  mascara MODIFY|CREATE|DELETE|CLOSE_WRITE|MOVED_*. Drain en cada poll().
- Windows: ReadDirectoryChangesW overlapped + GetOverlappedResult no
  bloqueante. Para vigilar un archivo, registra el directorio padre y filtra
  por nombre exacto en el poll().
- Otros: stub — poll() devuelve vacio y last_error() reporta no soportado.

API en namespace fn:: con tipos opacos (FileWatcher PIMPL). Errores via
last_error() en vez de excepciones. Documentadas las limitaciones (limite de
inotify watches en Linux, granularidad directorio-level en Windows, no
recursividad).

egutierrez 24905eebc7 feat(cpp/core): add text_editor_cpp_core component (PIMPL)
Wrapper en namespace fn:: sobre ImGuiColorTextEdit. La API publica solo expone
TextEditorState como tipo opaco; el TextEditor del vendor vive dentro del .cpp.

Soporta CodeLang::{Generic, GLSL, SQL, Cpp} (highlighting via las
LanguageDefinition del vendor). text_editor_render() devuelve true en el frame
en que el contenido cambia; flag dirty manejado independientemente para casos
"editado pero aun no guardado".

text_editor_get_text() cachea el resultado en un std::string del state para
mantener el const char* valido entre llamadas (el GetText() del vendor devuelve
std::string por valor).

Añade demos_gl_texture.cpp (carga assets/sample.png con la nueva
funcion gl_texture_load_cpp_gfx, muestra w/h/channels y sliders de
tint RGB + zoom UV via ImGui::ImageWithBg) y un PNG damero 256x256
generado para la demo.

Tambien registra apps/primitives_gallery como subdirectorio en

añade el hook de build).

Para integrarse, demos.h, main.cpp y CMakeLists.txt de la gallery
deben anadir respectivamente la declaracion gallery::demo_gl_texture(),
la entrada {"gl_texture", "gl_texture_load", "Gfx", &gallery::demo_gl_texture}

egutierrez ac65791663 feat(shaders_lab): per-node preview thumbnails + double-rclick delete node
- DagStep: preview_open flag (default false).
- dag_compile: emit `uniform int u_preview_target` and a series of
  early-return branches at the start of fragColor selection. -1 (default)
  falls through to the real Output-driven fragColor.
- dag_node_previews (new fn): per-node FBO keyed by editor_uid, lazy
  created. Renders each node with preview_open=true to its FBO by
  setting u_preview_target = step index. Texture exposed via
  dag_preview_texture(uid) for ImGui::Image.
- dag_node_editor: small toggle button "[+] preview"/"[-] preview" in
  each non-Output node; when open, ImGui::Image(96x64, V-flipped).
- dag_node_editor: double right-click on hovered node deletes it
  (Output is protected).
- main.cpp: dag_previews_render after Canvas DAG; dag_previews_destroy
  on shutdown.

Single GL program drives both the canvas and all thumbnails — moving
sliders never recompiles, only the topology change does.

egutierrez a209afa46b feat(shaders_lab): pins straddle node edges (half outside, half inside)
draw_pin_circle takes a PinSide and centers the circle exactly on the
left or right edge of the node. The reserved Dummy is half-width
(PIN_RADIUS instead of PIN_DIAMETER) so the inside layout stays
compact, and ed::PinRect is set to the full circle so the protruding
half is still grabbable.

egutierrez 426a842e2b feat(shaders_lab): pins on node edges, neutral color, right-click clears
- Pin radius bumped to 9px (18px diameter). Easier to grab.
- Single neutral pin/cable color across all kinds (data is uniformly
  vec4 — coloring by node kind was misleading).
- ed::StyleVar_NodePadding(0,8,0,8): zero left/right padding so the pin
  circles sit flush with the node's edges, separated from the title
  and controls by 8px gaps.
- Right-click on a pin clears all connections on that pin:
  - input pin → clear that single slot's source_id
  - output pin → clear every source_id across the pipeline pointing
    to this node (fan-out).
- Right-click on a link still deletes that single link (existing).

egutierrez 075088b7aa feat(shaders_lab): big colored pin circles, side layout, right-click delete
- Three-column node layout: input pins on the left edge, controls in
  the middle, output pin on the right edge.
- Pins rendered as 14px filled circles with darker outline. Color is
  the node's kind (gen=blue, op=violet, blend=amber, output=red).
- ed::PinPivotAlignment(0,0.5)/(1,0.5) so the cable starts/ends at
  the circle center.
- Empty columns (gen with no inputs, output with no output) get a
  pin-sized Dummy so column widths stay consistent.
- ed::Link now passes color (= source node kind) and 2.5px thickness.
- Right-click on a link deletes it immediately via
  ed::ShowLinkContextMenu (no popup).

egutierrez 144b15f0ce fix(shaders_lab): cycle check uses real reachability, not vector index
Previously the cycle validator rejected any link whose source had a
vector index >= target's, which silently killed legitimate connections
between nodes added in the wrong drop order.

Switch to a DFS over source_ids: an edge from->to creates a cycle iff
`from` already (transitively) depends on `to`. topo_sort runs after
each topology change so the vector ends up in a consistent order
regardless of how nodes were inserted.

egutierrez c2e4f6a9e1 fix(shaders_lab): Output connectable after drop + working color picker
Two bugs:

1. Dropped nodes were pushed to the end of the pipeline, but the Output
   node already sat there from startup. The cycle validator and the
   compiler only look for sources at indices strictly lower than the
   target, so new nodes were invisible to the Output. Fix: insert
   dropped nodes before the first Output; topo_sort also stable-moves
   Output nodes to the back.

2. ColorEdit3 with default flags rendered RGB text inputs alongside the
   swatch; clicking them dragged the node instead of opening the picker.
   Fix: NoInputs + NoLabel leaves only the swatch (a single item), and
   ed::Suspend/Resume wraps the call so the popup isn't clipped to the
   node or captured by the canvas.

egutierrez e3cfab3dc7 fix(shaders_lab): drop zone no longer eats node/slider input + inline tests
The previous InvisibleButton captured mouse events, so you could drag
from the Functions palette into the canvas, but node dragging and
slider interaction inside the canvas stopped working.

Fix: watch the global drag-drop payload without an explicit target. When
the mouse releases LMB over the DAG window with a "DAG_NODE_TYPE"
payload active, queue an add at that canvas position. No button, no
capture.

Tests (compiled standalone with preprocessor defines):
- dag_compile: 6/6 asserts (empty, single gen, op chain, multi-source
  blend, Output-driven fragColor, unconnected-Output fallback).
- dag_catalog: 8/8 asserts (uniqueness, per-kind input invariants,
  exactly one Output, body_glsl present & returns, control param
  indices valid).
Build with:
  g++ -std=c++17 -Icpp/functions -DDAG_COMPILE_TEST cpp/functions/gfx/dag_compile.cpp cpp/functions/gfx/dag_catalog.cpp -o /tmp/dag_compile_test

- dag_catalog: "output" node (1 input, red)
- dag_compile: skips Output in node_<i> emission; final fragColor resolves from Output's connection
- dag_node_editor: no more Add button; drops "DAG_NODE_TYPE" payloads at mouse canvas position; Output cannot be deleted; Output has no output pin
- dag_palette (new fn): Functions window with grouped, draggable node cards

egutierrez 42957d10f6 fix(shaders_lab): node drag was overwritten by SetNodePosition each frame
Previously SetNodePosition was called after EndNode every frame, which
reset any drag the user had done. Now the initial position is set once
per editor_uid (tracked in a static unordered_set), and the editor owns
the position afterwards. GetNodePosition at end-of-frame keeps step
state in sync for future persistence.

egutierrez 3f622561ce feat(cpp/viz): static-plot primitive + tooltips + rotated labels + card compacta
Nuevo primitivo compartido:
- cpp/functions/viz/plot_static.h: header-only con flags ImPlotFlags /
  ImPlotAxisFlags agrupados (NoFrame|NoMenus|NoBoxSelect|NoMouseText +
  Lock|NoInitialFit|NoHighlight) para visualizacion estatica en
  dashboards. Lo usan todos los charts de viz/.

Charts refactorizados a v1.1 con parametro `height` explicito (rompe el
feedback loop con contenedores AutoResizeY que producia vibracion al
redimensionar) y ejes pineados con ImPlotCond_Always:
- bar_chart v1.2: tooltip al hover (label + valor) + auto-rotacion de
  labels a 45 cuando no caben horizontalmente (medidos con CalcTextSize
  vs ancho del plot). Los labels rotados se dibujan manualmente con
  ImDrawList::PrimQuadUV + ImFontBaked::FindGlyph (API ImGui 1.92+).
- pie_chart v1.1: tooltip por slice (detecta cual via atan2 desde centro
  en sentido CCW matematico, que es como ImPlot dibuja los slices desde
  angle0=90) con label + valor + porcentaje. Aspect 1:1 mantenido.
- line_plot, scatter_plot, histogram v1.1: ejes pineados con limites
  calculados de min/max + 5% headroom (histogram usa AutoFit por los
  bins dinamicos, con Lock para bloquear pan/zoom).

kpi_card v1.2: card mas compacta — altura 78px (antes 108), font scale
1.4x (antes 1.8x), padding sm (antes md). Apto para densidades altas
de KPIs en dashboards.

fullscreen_window v0.2: NoScrollbar|NoScrollWithMouse para eliminar el

egutierrez 6f269949f1 feat(shaders_lab): independent windows for Code, DAG, Controls, Canvas, GLSL
Remove Code/DAG toggle. Each panel lives in its own dockable window.
Active source (Code or DAG) is whichever window has focus; Canvas title
shows the current active source. Switching active source triggers an
immediate recompile so the canvas reflects the selected pipeline.

egutierrez bdce314199 feat(shaders_lab): drag-and-drop to reorder DAG steps
ImGui native BeginDragDropSource/Target over each CollapsingHeader.
Drag source adjusted if ahead of target to keep final position correct.
Move Up/Down buttons kept for keyboard/touchpad fallback.

egutierrez b828fd6acc feat(cpp/viz): kpi_card v1.1 + bar_chart v1.1 — contenedor y altura fijas
kpi_card:
- v1.1: envuelve el contenido en BeginChild con surface bg + border +
  radius::md + padding::md (tokens). Replica Mantine Paper withBorder
  radius="md" p="md" usado en @fn_library/kpi_card.tsx.
- Ancho adaptativo via GetContentRegionAvail — requiere contenedor que
  propague ancho constrained (ImGui::BeginTable). dashboard_grid / BeginGroup
  no funcionan porque no constrainen ancho y la card desborda la celda.
- Linea de trend SIEMPRE visible: delta, sparkline, o em dash (text_dim)
  como placeholder, para que un grid de KPIs quede alineado vertical.
- Colores del delta via tokens (success/error) en vez de hardcoded ImVec4.

bar_chart:
- v1.1: altura explicita como parametro (default 200px). Sin esto, ImPlot
  con ImVec2(-1, 0) entra en feedback loop cuando esta dentro de un
  dashboard_panel (BeginChild con AutoResizeY): plot pide espacio -> padre
  se redimensiona -> plot recalcula. Efecto visual: las barras se deslizan
  los primeros frames.
- Ejes blindados: Lock + NoInitialFit + Cond_Always ademas de los flags
  previos. Y max pre-calculado con 15% de headroom.
- Sin inputs (NoInputs|NoFrame|NoBoxSelect|NoMouseText): estos charts son
  de resumen, no de exploracion.

Actualizados los .md correspondientes con el contrato visual + requisitos
de contenedor, para que cualquier dashboard que componga estos primitivos
obtenga el mismo look.

egutierrez d7c3daaa6b chore: untrack sqlite_api + registry.db, expand fn_monitoring docs
- sqlite_api se extrae a su propio repo Gitea (dataforge/sqlite_api),
  siguiendo la convencion de apps/*/ (cada app = su repo).
- registry.db ya estaba en .gitignore (regenerable con fn index +
  fn sync), pero seguia tracked por historia. Destracked.
- project.md de fn_monitoring ampliado con operacion completa:
  arranque del service (dev / start.sh / systemd user), flujo de
  datos dashboard, troubleshooting, como extender.

egutierrez e39445dd55 feat(cpp/core): design tokens + primitivos UI para dashboards ImGui
Trasladar principios del DESIGN_SYSTEM.md de @fn_library (Mantine/React)
al mundo C++/ImGui sin añadir deps externas:

  cpp/functions/core/
    tokens       — colors/spacing/radius/font_size como constexpr +
                   apply_dark_theme() al ImGuiStyle global. Dark + indigo
                   primary (Mantine-inspired).
    badge        — etiqueta inline 6 variantes (Default/Success/Warning/
                   Error/Info/Outline). <Badge> de @fn_library en C++.
    empty_state  — placeholder centrado para tablas/listas vacías.
    page_header  — header con title + subtitle + separator + hueco
                   para acciones (patrón begin/end).

Scope limitado (KISS) a fases 1-2 del plan: tokens + 3 primitivos.
No se duplica dashboard_panel con un "card" — el existente ya cumple
el rol. Fases 3-5 (charts ImPlot line/area, app_shell con navbar,
toast/alert) quedan fuera hasta que el dashboard crezca en alcance.

Resultado:
- 869 funciones (+4) en registry.db.
- Dashboard con header homogéneo y empty states en todas las tablas.
- Sin hardcode de ImVec4 disperso en views.cpp.

Diary + CHANGELOG actualizados.

egutierrez 32fc008cae docs: añadir ADR, diario, CHANGELOG y comando /entrada_diario
Infraestructura de documentación operativa y de decisiones:

- docs/adr/ — Architecture Decision Records. Incluye plantilla y
  ADR 0001 documentando el experimento y retirada de GitButler.
- docs/diary/ — diario de avances con un archivo por día.
  Primera entrada 2026-04-24.md retrocubriendo esta sesión
  (conectar aurgi-pc, dashboard fn_monitoring, funciones systemd
  locales, ADR GitButler, regla KISS).
- CHANGELOG.md — formato Keep a Changelog para cambios cara a
  usuario/agentes. Sección 2026-04-24 con Added/Changed/Fixed/Removed.
- .claude/commands/entrada_diario.md — slash command para añadir
  entradas al diario con formato consistente.

Separación:
  diary   = contexto operativo diario
  CHANGELOG = qué cambió en el código
  ADR     = por qué se decidió algo
  rules   = reglas operativas del agente

egutierrez 28ff9c3f79 docs(rules): añadir regla KISS para proyectos y apps
Formaliza la filosofía de mantener projects/ y apps/ simples:
- preferir herramientas del sistema o del registry antes que paquetes
  externos,
- cuestionar cada nueva dependencia (coste/beneficio, riesgo upstream),
- evitar abstracciones especulativas,
- ser consciente del flujo de trabajo actual.

Incluye el aprendizaje del experimento con GitButler (retirado en commit
correspondiente de repo_Claude) como caso concreto de una herramienta
externa que añadió complejidad sin beneficio en nuestro contexto.

egutierrez ab226d7137 feat(bash/infra): servicios systemd locales — 6 funciones atómicas + 1 pipeline
Nuevas primitivas para gestionar servicios systemd del sistema desde
el registry (antes solo había versiones remotas via SSH para deploy VPS):

  bash/functions/infra/
    systemd_local_install_unit   — escribir unit en /etc/systemd/system + daemon-reload
    systemd_local_enable         — systemctl enable
    systemd_local_start          — systemctl start + MainPID
    systemd_local_restart        — systemctl restart + MainPID
    systemd_local_status         — ActiveState/SubState/pid/enabled + journal tail (no sudo)
    systemd_local_uninstall      — stop + disable + rm unit + daemon-reload (idempotente)

  bash/functions/pipelines/
    install_systemd_service      — pipeline que compone las anteriores; args
                                    --name --exec [--workdir --user --env KEY=VAL
                                    --after --restart --type]

Requisito: sudo sin password para systemctl + escritura en /etc/systemd/system/.
En WSL: systemd=true en /etc/wsl.conf.

Registrado sqlite_api como servicio del sistema con este pipeline, queda
vivo al arrancar WSL. Dashboard ya no necesita arrancar la API manualmente.

egutierrez 8a96ebe412 chore: gitignorar registry.db + registrar submódulo GLFW
- registry.db ahora gitignored y regenerable con 'fn index' +
  completable con 'fn sync'. Evita conflictos entre ramas / PCs.
- Re-registrar submódulo cpp/vendor/glfw en .gitmodules con path
  limpio (antes heredado con /home/lucas/...). Necesario para el
  cross-compile Windows del registry_dashboard.

egutierrez f79f2e757c docs: add sync_setup.md — procedure to link a PC to registry.organic-machine.com
Covers the client-side linking flow (not the server deploy, which
already lives in bash/functions/infra/setup_registry_api.md):

- Requisitos: server UP, fn binary, pass con 3 entradas, GPG desbloqueada.
- Paso 1: ~/.fn_pc (identidad).
- Paso 2: FN_REGISTRY_API + REGISTRY_API_TOKEN — 3 opciones (zshrc snippet
  desde pass, direnv por proyecto, a mano por sesión).
- Paso 3-4: verificar con fn sync status + primer fn sync.
- Troubleshooting table (401, 403, localhost:8420, GPG cache, etc).

docs/README.md enlaza al nuevo fichero. registry.db actualizada tras
primer sync contra el server desde esta sesión.
