Los headers usaban uint8_t/uint32_t en enum-base-types (ColorRuleKind,
CellRenderer, TableEventKind) y en StringPool sin incluir <cstdint>/<cstddef>.
MSVC los arrastra transitivamente; GCC no, lo que rompia la compilacion del
modulo data_table y de toda app que lo enlaza (registry_dashboard, etc.) en
Linux nativo. Una sola cabecera afectada; el resto los obtiene transitivamente.

Foundation (ce7470d5) + reader rewire (2f7fdd40).
- ColumnSnapshot per col (i64/f64/str_ids) + StringPool per-State
- compute_visible_rows filter/sort uses snapshot direct numeric/id compare
- StringPool realloc-crash fix (reserve before emplace_back)
- Pool staleness sentinel (rebuild when string_pool.size() drift)
- High-cardinality cap (>2048 unique → skip interning, fallback raw)
API publica intacta. Bench 100k sort_numeric +131% vs baseline.
text_editor_smoke RED preexisting unrelated.

Change 3 of issue 0133 — rewire compute_visible_rows, filter eval,
and sort comparators to read from the SnapshotCache when available.
Hot paths rewired:
- compute_visible_rows (overload with snap): filter eval uses
compare_snap (fast i64/f64 numeric compare for Int/Float cols;
id-compare for low-cardinality string Eq/Neq; raw cells fallback
for Contains/StartsWith/EndsWith).
- Sort comparators: direct i64/f64 array compare for Int/Float cols
(goto sort_done skips string fallback); string sort uses uint32_t
id compare with pool lookup only on mismatch.
- Stage>0 filter/sort: same snapshot overload.
Materialization paths (build_so, s0_backing, mat_backing, config popup)
kept on raw cells — they copy into std::string anyway, no benefit from
snapshot and snprintf-per-cell was 2M extra calls per frame.
Bug fixes (required for correctness):
1. StringPool::intern() realloc safety: force reserve before
emplace_back so string_view keys in the map never go dangling.
2. SnapshotCache::pool_size_built sentinel: detects when a new State
is created with an empty pool but same cells pointer (begin_scenario
pattern). Prevents str_ids from indexing into an empty pool (SIGSEGV).
3. Cardinality cap (2048 uniques / 25% sample): high-cardinality string
cols (timestamps-as-strings, UUIDs, names) skip interning — str_ids
stays empty and compare_snap falls back to raw cells. Prevents 30MB+
pool bloat that hurt cache for filter/sort on other cols.
Bench delta vs baseline (100k rows, LIBGL_ALWAYS_SOFTWARE=1):
linear_scroll: 16.0 -> 15.5 fps p50 (-3%, baseline already FAIL)
filter_like: 59.7 -> 56.0 fps p50 (-6%, still PASS at 56fps)
sort_numeric: 3.9 -> 9.0 fps p50 (+131%, snapshot i64 sort)
color_rule: 15.2 -> 14.8 fps p50 (-3%, baseline already FAIL)
Build: green for all 10 available Linux consumers (text_editor_smoke
linker failure is preexisting, not caused by this change).
API public intact. TableEvent.row indexing TableInput preserved.
Pointer-identity invalidation preserved.

terminal_panel.cpp:
- BeginChild con PushStyleColor(ChildBg, negro) + PushStyleColor(Text, gris claro)
- PushStyleVar(WindowPadding, 8/6px) para padding terminal real
- Input prompt siempre visible cuando readonly=false
- Prefijo "$ " antes del InputText (TextUnformatted + SameLine)
- BeginDisabled() cuando el shell esta cerrado (en vez de ocultar el widget)
- Calculo de child_h reserva exactamente GetFrameHeightWithSpacing+6 para el prompt
cpp/tests/e2e/test_terminal_panel_e2e.py (nuevo):
- 4 asserts: PNG existe, no todo-blanco, region oscura >= 30%, pixels no-negros >= 0.3%
- Lanza primitives_gallery --capture, busca el binario Linux o Windows.exe automaticamente
- Skip graceful si no hay GL ni binario (WSL/CI headless)
- 4/4 pasan en Linux con LIBGL_ALWAYS_SOFTWARE=1

Change 1 — Columnar Snapshot Internal:
- Add ColumnSnapshot struct (type + str_ids/i64/f64 per column) in data_table_internal.h
- Add SnapshotCache struct with pointer-identity sentinel (last_cells_ptr)
- Add SnapshotCache field to UiState singleton
- In render(): rebuild snapshot after join materialization when cells ptr changes
Uses same pointer-identity pattern as existing stats_last_cells in State
Int/Float columns parsed once via parse_number; String/Auto interned
Change 2 — String Interning:
- Add StringPool struct (strings + unordered_map<string_view, uint32_t>) to data_table_types.h
- StringPool is per-State (NOT global) for table isolation
- intern(sv) inserts if absent, returns stable uint32_t index
- Cleared + rebuilt on each snapshot rebuild for index coherence
- Add string_pool field to State struct
Documentation:
- Extended header comment in data_table_internal.h describing design,
StringPool API, invariants (pointer-identity, row→snapshot_row),
and how stats_last_cells and snapshot coexist independently
Build: fn_module_data_table + tables_qa pass, no new errors (only
pre-existing -Wformat-truncation warnings unrelated to this change).
Public API (data_table.h, TableInput, render() signature) unchanged.

POSIX popen routes via /bin/sh -c, so "2>&1" is a shell redirect. On
Windows we use CreateProcessW directly (no shell): curl receives "2>&1"
as a positional arg, treats it as a second URL, and fails with exit 3
"URL rejected: Bad hostname".
Stderr is already merged into the same pipe via STARTUPINFOW.hStdError
on Windows, so the redirect is also unnecessary there. Guard with
#ifndef _WIN32.
Also adds FN_HTTP_DEBUG env var to dump the cmdline + req.url for
future bug triage (zero-cost when unset).
Detected via agents_dashboard.exe --connect-test against
https://agents.organic-machine.com — same .exe with the fix now returns
"OK 11" in <2s.

Incluye:
- dev/flows/0008-kanban-cpp-and-agent-workflows.md
- dev/issues/0112-0119*.md (7 sub-issues)
- WIP previo en cmd/fn/doctor.go, registry/*, modules/, cpp/, etc.

Frontmatter + self-doc sections (Ejemplo, Cuando usarla, Gotchas) following
the contract in .claude/rules/function_growth_and_self_docs.md. Tags include
'http', 'client', 'curl', 'network', 'registry-gap', 'helper' so FTS surfaces
them when an agent asks for HTTP / fetch / GET / Bearer.
http_get_json declares uses_functions: [http_request_cpp_core] so the
dependency is auditable via mcp__registry__fn_uses.
Promotes the inline curl-popen pattern duplicated across apps/services_monitor,
dag_engine_ui, data_factory into two reusable functions in cpp/functions/core/:
- http_request_cpp_core: generic HTTP client (GET/POST/PUT/DELETE/PATCH) via
cURL CLI through popen. Portable Linux/WSL/MinGW (no link-time libcurl).
Supports custom headers, raw body, Bearer/Basic auth shortcuts, timeout,
optional TLS verify skip. Returns status/body/headers/error/duration_ms.
- http_get_json_cpp_core: convenience wrapper over http_request — GET <url>,
expect 2xx, parse body as nlohmann::json. Throws std::runtime_error on
transport / non-2xx / parse failure.
Vendors nlohmann/json v3.11.3 single header at cpp/vendor/nlohmann/json.hpp
(MIT). No CMake target needed — header-only; consumers add
cpp/vendor/ to include path.
- Replace TextColored+glyph with ImDrawList::AddCircleFilled in CellRenderer::Dots.
Dots are now font-independent: no dependency on Unicode glyph coverage. Fixes
"dots show as ?" on Karla/Roboto/Inter fonts that lack Geometric Shapes block.
- dots_glyph_size now controls circle radius (px) instead of font scale.
- BadgeRule.label is ignored for Dots (documented in data_table_types.h + docs).
- data_table.md bumped to v1.3.1 with capability growth log entry.
- docs/capabilities/data_table_renderers.md: Dots section updated + Common pitfalls
entry added: "Asumir que cualquier glyph Unicode renderea".
- dag_engine_ui/tabs.cpp: removed stale "● glyph" comment from BadgeRule.
- Recompiled: dag_engine_ui, registry_dashboard, graph_explorer, navegator_dashboard,
odr_console. All 5 apps deployed to Desktop/apps/. Build Linux + tests 4/4 green.

Tamano FIJO del popup (Always + SizeConstraints) y flags NoResize/NoMove
para evitar feedback loop entre auto-resize del popup y TextWrapped/SameLine
internos. Reemplaza GetWindowContentRegionMax() por offsets explicitos
calculados a partir del ancho fijo, ya que ese valor fluctua frame a frame

Tres kernels Monte Carlo intensivos sobre las primitivas G1-G7 + las puras
CPU como oraculo de tests numericos. Apuntados a hyper-paralelizar los
calculadores de sources/calculadoras (vr_tiered_lab, mcmc-bayes / full / lab,
mcmc-visualizer) en RTX-class GPUs.
- mc_session_sim_gpu (K1): N sesiones independientes de K spins en paralelo
(1 thread = 1 sesion). Modelo variable-ratio escalonado con tiers (q, m),
modes Pure/Pity/Streak, miss_streak, drawdown. SSBOs summary[N*8] y
tier_counts[N*max_tiers]. Portea vr_tiered_lab.
- mc_metropolis_hastings_gpu (K2): M cadenas independientes 1D. Target
log-pdf inyectable como string GLSL (mismo patron de gl_shader). u_user[16]
para cambiar parametros desde sliders sin recompilar. Output compatible
con rhat_split / ess_basic.
- mc_random_walk_2d_gpu (K3): walkers 2D MH con trace_xy xy-interleaved en
SSBO; pasable directamente a gpu_histogram_2d sin readback intermedio.
Pipeline GPU-only para mcmc-visualizer.

Cuando una funcion del registry parte su .cpp en varios TUs por testabilidad
o separacion ImGui-vs-puro, cada TU adicional se registra como entrada propia
con su .md en lugar de extender file_path para listar varios archivos.

- graph_viewport_selection_cpp_viz: clear/add/toggle/is_selected puros.

Refina la convencion de layout: el top de cada app distribuible
solo lleva el .exe + DLLs nativas; todo lo demas (TTFs, enrichers,
runtime Python, MCP servers) vive en <exe_dir>/assets/.
Cambios:
- cpp/CMakeLists.txt::add_imgui_app — copia las 5 TTFs (Karla,
Roboto, DroidSans, Cousine, tabler-icons) a
$<TARGET_FILE_DIR>/assets/ en lugar de junto al exe.
- framework/app_base: nuevas funciones fn::asset_dir() y
fn::asset_path(name) que resuelven a <exe_dir>/assets/<name>.
- functions/core/icon_font.cpp::find_asset — anade
fn::asset_path(filename) como PRIMERA ruta de busqueda, antes
de las legacy ./<file> y ./assets/<file>. Mantiene los
fallbacks para dev (FN_ASSETS_DIR, FN_CPP_ROOT).
- .claude/commands/compile.md — el deploy a Desktop pone TTFs +
enrichers/ + runtime/ + gx-cli en <DEST>/assets/. Solo .exe y
DLLs nativas (duckdb.dll) quedan en el top. local_files/ se
preserva si existe.
Layout final:
Desktop/apps/<APP>/
├── <APP>.exe + *.dll (binario + DLLs Windows)
├── assets/ (read-only distribuible)
│ ├── *.ttf, enrichers/, runtime/, gx-cli, ...
└── local_files/ (per-PC, creado al primer arranque)
Esto cierra la separacion conceptual de la convencion: la carpeta
es trivial de zippear (solo .exe + assets/), el reset/sync es
trivial (local_files/), y todas las apps del registry adoptan el
mismo layout via fn_framework.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Toda app C++ basada en fn::run_app coloca sus archivos escribibles
bajo <exe_dir>/local_files/. Los distribuibles (.exe, dlls, ttfs,
enrichers/, runtime/) siguen junto al .exe. Esto deja la carpeta
distribuible limpia para zippear y separa con claridad lo que
viaja con la app de lo que el PC genera.
API publica en fn:: (cpp/framework/app_base.h):
- exe_dir() directorio del ejecutable
- local_dir() <exe_dir>/local_files/, creado on-demand
- local_path(name) <local_dir>/<name>
- migrate_to_local_files(...) mueve archivos viejos desde cwd/exe_dir
Cambios:
- run_app configura io.IniFilename = local_path("imgui.ini") y
llama migrate_to_local_files(["imgui.ini","app_settings.ini"])
antes de settings_load(). Migracion idempotente para PCs con
instalacion previa.
- app_settings.cpp usa local_path("app_settings.ini") en lugar de
hardcoded "app_settings.ini" relativo al cwd.
- cpp_apps.md §7 documenta la convencion como obligatoria. Las
apps deben usar fn::local_path() para cualquier archivo
escribible nuevo.
Beneficios:
- zip distribuible no se "ensucia" con .ini/.db generados al usar.
- reset trivial: borrar local_files/.
- backup/sync per-PC: solo local_files/ es propio del PC.
- elimina la mezcla de paths Linux/Windows que generaba bugs como
"projects\\default\\operations.db" en builds cross-platform.

- graph_labels_draw_at(...) — variante con rect explicito
- graph_labels_select(...) — helper puro testeable
- graph_compute_degrees(...) — O(E)
Splitting en dos TUs:
- graph_labels.cpp — funciones draw (depende de ImGui)
- graph_labels_select.cpp — helpers puros para tests sin ImGui
12 tests en test_graph_labels (culling, max_visible cap, min_pixel_size,
always_* gating por viewport, top-N por score, edge cases). Todos verdes.
Integrado en demos_graph con UI: toggle Labels, sliders Max visible /
