PhotoCraft (Design editor: photo adjustments)
---------------------------------------------
Shadows/Highlights, the Auto Tone / Auto Contrast / Auto Color commands,
Sharpen and Replace Color in the Design editor (`lib/graphics/adjust/tono.ts`
and `lib/graphics/adjust/retoque.ts`) are a TypeScript adaptation of code
from PhotoCraft, upstream commit ba9272be7 (2026-10-06): `crates/algo/src/`
`tone.rs`, `sharpen.rs` and `selection.rs`, and
`crates/engine/src/edit_cmds.rs`. The Lighten / Darken / More color /
Less color brush (`lib/graphics/paint/aclarar.ts`, with its tests) is a
TypeScript adaptation of PhotoCraft v0.2.0 `crates/algo/src/retouch.rs` (the
Dodge, Burn and Sponge kernels, and their tests) and
`crates/engine/src/retouch_cmds.rs` (the per-dab strength). Also adapted
from PhotoCraft v0.2.0, each with the upstream tests it could carry:
  - the Paint Bucket and Erase Color tool (`lib/graphics/paint/bote.ts`):
    `crates/algo/src/selection.rs` (`wand_region`, `magic_wand`, `antialias`),
    `paint.rs` (`bucket_fill`) and `erase.rs` (`magic_erase`);
  - Straighten (`lib/graphics/adjust/enderezar.ts`): the Transform part of
    `crates/algo/src/lens.rs` (`LensMap`, `auto_scale`, `straighten_angle`,
    `remap`). The automatic angle detection in that file is Olynx's own;
  - Remove Grain (`lib/graphics/adjust/quitarRuido.ts`):
    `crates/algo/src/denoise.rs` in full and the box / Gaussian helpers of
    `fxutil.rs`. The grain measurement and the strength mapping built on it
    in that file are Olynx's own;
  - Mosaic (and the one-click "Cover" built on it), Color Halftone,
    Crystallize, Facet, Fragment, Mezzotint and Pointillize
    (`lib/graphics/adjust/pixelar.ts`): `crates/algo/src/pixelate.rs` in
    full, `mosaic` from `stylize.rs`, `hash01` from `noise.rs`,
    `cell_point` and `unpremul_px` from `fxutil.rs`, the halo / output-area
    rules of `lib.rs`, and the dialog ranges of `crates/engine/src/`
    `filters.rs` and `filters_ext.rs`;
  - Brightness / Contrast, Vibrance, Photo Filter, HDR Toning, Posterize,
    Threshold, Equalize, Unsharp Mask and High Pass — plus Channel Mixer,
    Selective Color and Match Color, ported but not yet offered in the
    editor — (`lib/graphics/adjust/masAjustes.ts`): `crates/algo/src/`
    `tone.rs` (`lab_stats`, `match_color`, `hdr_toning`), `sharpen.rs`
    (`unsharp`, `high_pass`) and `blur.rs` (`gaussian_kernel`, `conv_sep`);
    the matching branches of `crates/compose/src/adjust.rs`;
    `crates/engine/src/extra_cmds.rs` (`equalize`);
    `crates/color/src/convert.rs` (`srgb_to_lab`, `lab_to_srgb`); and the
    ranges and presets of `crates/engine/src/` `adjust_params.rs`,
    `adjust_cmds.rs` and `filters.rs`;
  - the Sharpen mode of the Smudge / Blur brush
    (`lib/graphics/paint/enfocarLocal.ts`): `local_blur` and `local_sharpen`
    from `crates/algo/src/retouch.rs` and the Sharpen Tool settings of
    `crates/engine/src/retouch_cmds.rs`;
  - Select Sky (`lib/graphics/selection/cielo.ts`): `crates/algo/src/`
    `segment/sky.rs` in full, with its tests; from `segment/gmm.rs` the
    Gaussian mixture model and `kmeans`; from `segment/mod.rs` `Rng`,
    `components`, `clean_mask`, `subsample`, `scale_for` and the block
    downsample; and `box_mean` and `guided_filter_gray` from
    `crates/algo/src/matting.rs`. The outward shift of the refined edge
    (`ensanche`) and searching photo by photo are Olynx's own:

WordCraft (Studio Doc: formulas, form fields, find, equations, citations, index, mailings, typing, page breaks)
---------------------------------------------------------------------------------------------------------------
Keep with next, keep lines together and page break before (`lib/studio-doc/paragraphBreaks.ts`)
came from cross-checking WordCraft's catalog of Word functions
(`crates/engine/src/catalog.rs`) against Doc; the code is Olynx's own.

What Studio Doc does as you type (`lib/studio-doc/wordTyping.ts`, the capitals and
dashes in `autoCorrect.ts`, and `wordTyping.test.ts`) follows WordCraft's record of
Word typed key by key, `docs/typing-parity.md`, and its tests in
`crates/engine/src/tests_typing.rs` (the mixed document typed side by side
included). The sample text, the Spanish abbreviations and the places where Doc
differs on purpose are Olynx's own.

The letter fields of Mailings — greeting line, address block and rules
(`lib/studio-doc/letterFields.ts`, with its tests) — and sorting and
filtering the recipients follow WordCraft's `crates/engine/src/cmd/mailings.rs`
(Word's «Write & Insert Fields» and «Edit Recipient List»). The fallback
greeting for a client without a name, rules that ignore case and accents,
the preview with the document's own client, the Spanish wording and the
address split as on an envelope (`envelopesLabels.ts`) are Olynx's own.

The citation and bibliography styles IEEE, Harvard (Anglia), ISO 690
(author-date and numerical), Turabian, GB/T 7714, GOST (name and title sort)
and SIST02 (`lib/studio-doc/citationStyles.ts`, with its tests) follow
WordCraft's `crates/engine/src/cmd/citations.rs`: each style as data (the
in-text citation, how names are written, the order of the list and the
entry templates). The index's subentries, cross-references and bold or
italic page numbers follow its `crates/engine/src/cmd/index.rs` (the switches
of Word's XE field). The italics, the Spanish wording, the example in the
style picker and Mark All by whole word are Olynx's own.

Equations in Studio Doc (`lib/studio-doc/equation.ts`, `equationOmml.ts`,
with their tests) read Word's linear format (UnicodeMath) and LaTeX the way
WordCraft does in `crates/doc/src/math_linear.rs` and `math_latex.rs` (the
operand of a large operator, limits with the two box characters, the grid
matrix, numbering with `#`, function names whose subscript goes underneath,
accents), and write the Office Math pieces of its model in
`crates/doc/src/math.rs` (n-ary operators with their limit location, lower
and upper limits, accents and bars, matrices, border boxes, equation arrays).
The drawn integral sign, the layout and Doc's own syntax (`sum_(i=1)^n`,
`matriz(a, b; c, d)`, `casos(...)`, `hat(x)`) are Olynx's own.

Find and replace in Studio Doc (`lib/studio-doc/wordFind.ts`, with its
tests) follows WordCraft's `crates/engine/src/cmd/find_pattern.rs`: Word's
special codes (^p, ^t, ^#, ^$, ^?, ^w, ^l, ^&, ^c, ^nnn and the rest) and its
wildcard language (?, *, [a-z], [!x], {n,m}, @, <, >, groups and \1 to \9),
with the find and replace cases of `crates/engine/src/tests.rs`. The search
engine that never backtracks (`wordFindMotor.ts`), how the document is read
and replaced into, paragraph marks included (`wordFindDoc.ts`), and the find
bar are Olynx's own.

The form fields of Studio Doc (`lib/studio-doc/formControls.ts` and
`formControlsWord.ts`, with their tests) follow WordCraft's content controls:
the model of `crates/doc/src/control.rs` and how they are written to and read
from a .docx in `crates/docx/src/write/sdt.rs` and `crates/docx/src/read/sdt.rs`
(the `w:sdtPr` order, the `w14` check box with its two symbols, `w:lastValue`,
`w:fullDate`). The blank line printed for an empty field, the "filling in
forms only" protection and the subset kept (check box, drop-down list, date,
text) are Olynx's own.

The table formulas of Studio Doc (`lib/studio-doc/tableFormula.ts`, with its
tests) are a TypeScript adaptation of code from WordCraft, upstream commit
fd0bb2f (2026-10-15): `crates/engine/src/cmd/table_formula.rs` (the parser,
the functions, the `\#` numeric pictures and their tests),
`formula_instr` and `auto_formula_instr` from `crates/engine/src/cmd/table.rs`,
and `crates/doc/src/locale_number.rs` (reading and writing a number the way
each language writes it, with its tests). Recalculating by dependency order,
the circular-reference check, merged-cell grids, decimal rounding and the
Spanish function names in that file are Olynx's own:

GridCraft (Studio Sheet: functions)
-----------------------------------
The worksheet functions added to Studio Sheet's formula engine
(`lib/studio-sheet/formula/compile.ts`: MROUND, TRUNC, EVEN, ODD, QUOTIENT,
PRODUCT, SIGN, the logarithms, the trigonometry, IFS, SWITCH, XOR, PMT, PV,
FV, NPER, RATE, IPMT and PPMT, and rounding to 15 significant digits before
ROUND, ROUNDUP and ROUNDDOWN take their decimals) are a TypeScript adaptation
of code from GridCraft, upstream commit f1894c6 (2026-10-15):
`crates/functions/src/financial.rs` (`pmt_calc`, `fv_calc`, `pv_calc`, `nper`,
`ipmt_calc` and `rate` with its Newton and bisection solver) and
`crates/functions/src/math.rs` and `util.rs` (`round_dir`, `round_half_away`,
`mround`, `even_odd`, `quotient`), with the expected values of their tests in
`lib/studio-sheet/formula/gridcraft.test.ts`. «Recently Used» follows
`recently_used` in `crates/engine/src/cmd/extra.rs`. The units each function
accepts and returns, what a blank cell does, the Spanish function names and
the translation to Excel are Olynx's own.

Paste Special in Studio Sheet (`lib/studio-sheet/pegadoEspecial.ts`, with its
tests) follows GridCraft's `paste_special` in `crates/engine/src/cmd/edit.rs`:
what to paste (all, values, formats, notes, all except borders, column
widths), the operation with what is already there and skip blanks. Keeping a
blank cell blank instead of treating it as zero, leaving calculated columns
alone and the sheet's own copy that carries formatting and notes are Olynx's
own.

Data validation in Studio Sheet (`lib/studio-sheet/validacion.ts`, with its
tests) follows GridCraft's `validation`, `check_validation`, `compare_op` and
`circle_invalid` in `crates/engine/src/cmd/data.rs` and its model in
`crates/model/src/features.rs`: the kinds, the comparison operators, ignore
blank, the input message and the stop, warning and information alerts. The
rule per column, the custom condition written with column names, circling
pasted values that break the rule and the check before sending are Olynx's
own.

Check boxes in Studio Sheet (the `check` column, with `casillas.test.ts`)
follow GridCraft's `checkbox` and `toggle_checkbox` in
`crates/engine/src/cmd/extra.rs`: a check box in the cell that a click or the
space bar ticks. A whole column of them, ticking every selected one at once,
a blank box counting as no (0) in formulas and the count on the total line
are Olynx's own.

Scenarios and data tables in Studio Sheet (`lib/studio-sheet/escenarios.ts`,
with its tests) follow GridCraft's `scenario_add`, `scenario_show`,
`scenario_summary` and `data_table` in `crates/engine/src/cmd/whatif.rs`:
saved sets of values to show and compare side by side, and a table of results
for a list of values of one or two inputs. Using the sheet's defined names and
bid percentages as the inputs, and the cost, bid price and margin as the
results, are Olynx's own.

Flash Fill in Studio Sheet (`lib/studio-sheet/rellenoRapido.ts`, with its
tests) is a TypeScript adaptation of `flash_fill`, `learn` and `synthesize`
in GridCraft's `crates/engine/src/fill.rs`, with the cases of its tests. The
finer split of letters and digits for building sizes, searching every text
column for the source and refusing a program made only of fixed text are
Olynx's own.

Custom number formats in Studio Sheet (`lib/studio-sheet/formatoNumero.ts`,
with its tests) are a TypeScript adaptation of GridCraft's `crates/numfmt`
(`parse.rs`, `render.rs` and `decimal.rs`: sections, conditions, colors,
digit placeholders, thousands and scaling, percent, scientific, fractions,
literals, fill, the text section, General, and Excel's rounding to 15
significant digits) and of `adjust_decimals` in
`crates/engine/src/cmd/format.rs`, with the cases of their tests. Leaving out
dates and times, and the list of codes offered to a contractor, are Olynx's
own.

"Show Values As" in the Studio Sheet PivotTable (`lib/studio-sheet/dinamica.ts`)
follows `PivotShowAs` in GridCraft's `crates/model/src/features.rs` and its
computation in `crates/engine/src/pivot.rs` (percent of grand, column and
row total, running total, rank). The report filter is Olynx's own:

  Each — MIT License OR Apache License 2.0
  Copyright (c) 2026 ArtCraft Team and the contributors of each program

Both license texts ship next to each program's files (`LICENSE-MIT`,
`LICENSE-APACHE`; VectorCraft, FilmCraft, LightCraft, PdfCraft and DesignCraft also ship the SIL Open Font
License texts of the fonts they bundle, and LightCraft and PdfCraft their own `NOTICE`), with an `ORIGEN.md` that says what was copied
and from where. The size and SHA-256 of every hosted file are fixed in
`lib/studio-pro/paquetes.ts`, and a test compares them with what is on disk.

Olynx shows each program inside a frame served from a different origin than
the app (`lib/studio-pro/origen.ts`, `components/studio-pro/TallerPro.tsx`),
so the program cannot read the Olynx session and keeps its own storage. The
programs' files are not changed. Their start page (`index.html`) is served
as published, with one Olynx script added in front of it
(`lib/studio-pro/puente.ts`) that only tells the Olynx page whether the
program has started and whether the user is working in it.

Tool icons. The icons Olynx shows for the seven tools
(`components/studio-pro/iconos/`, a light and a dark variant of each) are
Olynx's own artwork, drawn for Olynx on 2026-10-10; they contain no
third-party material. The programs' official app icons are not used by Olynx:
they appear only inside the programs' own unmodified builds. (From 2026-10-08
to 2026-10-10 Olynx showed each program's official icon, as its license
allows; those copies were removed.)

Names and marks. In Olynx each tool is shown under a name and an icon of
Olynx's own: "NX Photo", "NX Vector", "NX Film", "NX Light", "NX PDF",
"NX Motion" and "NX Pages". Which program each tool is — PhotoCraft,
VectorCraft, FilmCraft, LightCraft, PdfCraft, EffectCraft and DesignCraft,
in that order, each one unmodified — is stated in plain text in the tool's
credits inside Olynx and in this notice. Inside, each program keeps its own
name and icon, because its files are not changed. The ArtCraft name, wordmark
and mark are trademarks of the ArtCraft Team and are NOT open source
(`docs/brand/LICENSE-brand.txt` in each repository): the ArtCraft logo is not
used anywhere in Olynx outside those programs' own unmodified builds, and
ArtCraft is named only in plain text, as the team that makes the programs.
The names of the programs are their owner's. Olynx is not affiliated with,
sponsored by or endorsed by the ArtCraft Team.

OpenCut (Studio NX video editor: frame background, safe-zone guides, shapes)
----------------------------------------------------------------------------
The frame background of the Studio NX video editor — a plain colour, or the
clip itself enlarged to fill the frame and blurred, in three strengths
(`lib/studio-video/backdrop.ts`, `lib/studio-video/engine/blur.ts`,
`components/studio-video/Fondo.tsx`) — follows the "blur background"
feature of OpenCut (classic), upstream commit cf5e79e (2026-05-17):
`apps/web/src/background/blur.ts`, `apps/web/src/project/types.ts`
(`TBackground`) and `apps/web/src/services/renderer/scene-builder.ts`
(`buildBlurBackgroundNodes`). The viewer guides that show what each short-video
app covers (`lib/studio-video/guides.ts`, `components/studio-video/Guias.tsx`)
follow the idea of its platform guides (`apps/web/src/guides/`); the margins
were chosen by Olynx from publicly circulated guidance (none of the apps
publishes official ones) and no platform logo or screen mock-up is used. The
shapes drawn on top of the video — arrow, circle, box, line
(`lib/studio-video/shapes.ts`, `lib/studio-video/engine/shape.ts`,
`components/studio-video/Formas.tsx`) — follow the idea of its shape graphics
(`apps/web/src/graphics/definitions/`, `apps/web/src/stickers/providers/shapes.ts`):

  OpenCut (opencut-app/opencut-classic) — MIT License
  Copyright 2025-2026 OpenCut
  https://github.com/opencut-app/opencut-classic

Used under the MIT License; its full text is in
`lib/studio-video/LICENSE-opencut`. The idea and the option set were taken;
the code is Olynx's: OpenCut renders it with its GPU compositor, Olynx with
the same 2D canvas painter that draws the viewer and the exported file. No
OpenCut program, binary or interface is shipped. The OpenCut name and logo
are trademarks of their owner and are not licensed to Olynx.

soundtouchjs (Studio NX video editor: speed without changing the pitch)
----------------------------------------------------------------------------
When a clip of the Studio NX video editor is sped up or slowed down, its sound
is time-stretched so the voice keeps its pitch (`lib/studio-video/engine/stretch.ts`).
The stretching is done by the `Stretch` class of soundtouchjs 0.3.0, used
unmodified from its npm package:

  soundtouchjs — GNU Lesser General Public License, version 2.1
  Copyright (c) Olli Parviainen, Ryan Berdeen, Jakub Fiala,
  Steve 'Cutter' Blades
  https://github.com/cutterbl/SoundTouchJS

Its full license text is in `lib/studio-video/LICENSE-soundtouchjs`. The
library is loaded with a dynamic import, so the build keeps it in its own
script file, separate from Olynx's code: it can be replaced by another build
of soundtouchjs (its source is at the address above and on npm) without
changing anything else. Olynx's own code is not covered by the LGPL.

FilmCraft (Studio NX video editor: time base, project model, edit algebra)
---------------------------------------------------------------------------
The Studio NX video editor (`lib/studio-video/`, `components/studio-video/`)
is Olynx code. Its exact time base (`time.ts`), animated parameters
(`keyframes.ts`), effect and project model (`effects.ts`, `model.ts`) and
timeline edit algebra (`edit.ts`), with their tests, are a TypeScript
adaptation of code from FilmCraft v0.2.1, upstream commit 61ab6f5
(2026-10-06): `crates/time/src/lib.rs`, `crates/project/src/lib.rs`,
`keyframe.rs` and `effect.rs`, and `crates/edit/src/lib.rs` and `tests.rs`:

  FilmCraft (storytold/filmcraft) — MIT License OR Apache License 2.0

Used under the MIT License; its full text is in
`lib/studio-video/LICENSE-filmcraft`. What was kept and what was changed is
described at the top of each file. No FilmCraft program, binary or interface
is shipped: decoding and encoding use the browser (WebCodecs). The ArtCraft
and FilmCraft names and logos are trademarks of their owner and are not
licensed to Olynx.

Takeoff engine
--------------
Parts of the takeoff engine (`lib/takeoff/`, its components and its tests)
are adapted from open-source projects. Every adapted file names its source
in its first lines and lists what was changed for Olynx;
`lib/takeoff/licenses/README.md` lists them all, and the full license texts
are in that folder, each under its project's name.

them. Olynx is not affiliated with any of them.

Print Shop 3D t-shirt model
---------------------------
The 3D t-shirt in `public/print-shop/modelos/playera.glb` is the model of the
"T-Shirt Configurator" example by Paul Henschel, taken unchanged from:

  pmndrs/examples — MIT License
  Copyright (c) 2024 Poimandres
  https://github.com/pmndrs/examples
  (examples/t-shirt-configurator/src/shirt_baked_collapsed.glb)

Used under the MIT License; its full text is in
`public/print-shop/modelos/LICENSE-pmndrs-examples.txt`. The design is laid on
it at run time; the model file itself is not modified.

Compositor (Design editor: layers, tools, menus and their wording)
------------------------------------------------------------------
The Design editor's layers panel, several of its tools and commands, its menus
and their wording are a TypeScript port of parts of Compositor, written in
Swift. The port is in `components/graphics/compositor/` and in the other files
listed for it in `scripts/open-source-vendored.json`; each file names at the
top what it ports and what Olynx changed:

  Compositor (robbietilton/Compositor) — MIT License
  Copyright (c) 2026 Wonder Assembly LLC
  https://github.com/robbietilton/Compositor

The MIT License text is at the end of this file. The Compositor name belongs
to its owner and is used here only to credit it.

ScrollX UI (Studio NX: Magic Dock and Animated TextGenerate)
------------------------------------------------------------
The Studio NX create rail (`components/social/studio-nx/StudioNxDock.tsx`,
from ScrollX UI's Magic Dock) and the header's word-by-word subtitle
(`components/social/studio-nx/scrollx/animated-textgenerate.tsx`, from its
Animated TextGenerate) were installed into Olynx and adapted from:

  ScrollX UI (Adityakishore0/ScrollX-UI) — MIT License
  Copyright (c) 2025 Ahdeetai
  https://github.com/Adityakishore0/ScrollX-UI

What was changed is described at the top of each file. The MIT License text is
at the end of this file.

shadcn/ui (dialog, dropdown menu, popover, select, sheet, tooltip)
------------------------------------------------------------------
The dialog, dropdown menu, popover, select, sheet and tooltip primitives in
`components/ui/primitives/` are adapted from:

  shadcn/ui (shadcn-ui/ui) — MIT License, shadcn
  https://github.com/shadcn-ui/ui

The MIT License text is at the end of this file.

Studio NX Design fonts
----------------------
The fonts the Design editor offers (`public/fonts/graphics/`) are the Latin
subsets of families from Google Fonts, each under its own licence: the SIL
Open Font License 1.1, the Apache License 2.0 or the Ubuntu Font Licence 1.0.
`public/fonts/graphics/LICENCIAS-LIBRES.md` names each family's licence and
copyright notice, and carries the texts of the SIL Open Font License 1.1 and
the Apache License 2.0. The Ubuntu Font Licence 1.0 text is at
https://ubuntu.com/legal/font-licence. Each font file keeps its own copyright
notice inside it.

LibRaw (Design editor: developing camera RAW photos)
----------------------------------------------------
The Design editor develops camera RAW files in the browser with LibRaw,
compiled to WebAssembly by the libraw-wasm package and served from
`public/libraw/` as that package ships them, except that the
`sourceMappingURL` line was removed. LibRaw itself is unmodified.
`public/libraw/README.md` says what each file is:

  LibRaw 0.22.1 — Copyright (c) LibRaw LLC
    Offered under the GNU Lesser General Public License 2.1 or the Common
    Development and Distribution License 1.0; Olynx uses it under the
