Implements the shared exact media timebase crate (craft-time) for FilmCraft, SoundCraft, EffectCraft, and animation timeline consumers: - Exact Signed Timebase: Tick represents exact media time across [Tick::MIN, Tick::MAX] using TICKS_PER_SECOND = 254_016_000_000, supporting exact integer conversions for standard film, broadcast, audio, and high-framerate rates. - Total Arithmetic Contract: All operations are strictly panic-free under #![deny(clippy::panic)], providing checked_* methods and monotonic saturating division. - Timecode and Film Footage: Full SMPTE 12M drop-frame and non-drop-frame formatting, 35mm and 16mm feet+frames, broadcast zero-padded hours, and EffectCraft unpadded hours. - Differential Testing: 15 test suites incorporating full FilmCraft and EffectCraft parity vectors, boundary saturation tests, and proptest monotonicity invariants.

Craft App Libraries
This repo contains libraries used by the various Craft Apps. It's a Rust monorepo workspace, and the libraries can be included by any Craft Apps that need them.
In the future this may grow to include non-Rust library code.
If any libraries grow beyond Craft App usage, eg. RAW format support, they may be promoted out and into their own libraries for the broader ecosystem to take advantage of.
Layout
A Cargo workspace (edition 2024, resolver 3). Each library is a crate under crates/<name>, named
craft-<name>, with version, edition, license and repository inherited from the workspace
(license.workspace = true, and so on) and [lints] workspace = true. Register each crate in
[workspace.dependencies] in the root Cargo.toml.
Apps depend on a crate by git:
craft-<name> = { git = "https://github.com/storytold/craft-libs", rev = "<commit>" }
Libraries
-
craft-ai-core: the data model and contract for AI in the Craft Apps (connections, models, tools, requests, jobs, consent, history, route spec). Pure, no I/O, wasm-safe. Contract in docs/ai-shared-layer.md. -
craft-pdf: independently optional PDF parsing, interpretation, rasterization and guarded authoring. Apps retain layout, fonts, editing and export policy; writer-only consumers do not enable the shared reader. -
craft-atomic: Crash-safe atomic file writing and replacement with same-directory staging, directory fsync, AppleF_FULLFSYNCfallback, transient lock backoff, and fault injection for the Craft suite. -
craft-cms: pure-Rust ICC v2/v4 colour management: profile parsing and writing, transforms, rendering intents, black point compensation, soft proofing, gamut checks, 3D LUTs and built-in profiles (sRGB, Display P3, synthetic coated CMYK and others). -
craft-docpath: decides whether a path orfile:URL stored in a document may be opened. Paths stored in documents are followed only when they are local or on the document's own network share; other network paths, device paths and non-file URLs are refused. -
craft-i18n: translations over the embedded craft-i18n catalogs: lookup with fallback (pt-br→pt→ English), plurals, language names, the system locale and a pseudo locale. The catalogs stay a fully optional build input; apps keeptl!and their language setting. -
craft-print: PDF submission to CUPS and Windows, printer discovery, duplex/copies/colour and driver preferences. PDF generation stays in each app. -
craft-quit: native macOS quit, egui close handling and an optional app menu. Unsaved-document decisions and save prompts stay in each app. -
craft-settings:config.tomlsettings storage for every app: platform folders, portable mode and overrides, atomic saves while running, backup, damaged-file recovery and schema migrations. Policy in docs/settings-storage.md. -
craft-time: Exact media time base (TICKS_PER_SECOND = 254_016_000_000), rational frame rates, and SMPTE timecode (drop/non-drop frame, 35mm/16mm feet+frames) for FilmCraft, SoundCraft, EffectCraft, and animation timeline consumers. -
craft-ui: SVG catalogs, icon buttons, tabs, pane controls, transactional docking, print settings and theme helpers for egui frontends; assets, themes, localization and command handling stay in each app. Requires Rust 1.95 or later. -
Shared UI component audit: source inventory, extraction priorities and compatibility boundaries across the Craft suite.
-
Theme infrastructure: eight-app comparison and the small shared widget-state styling boundary.
-
Panel docking: validated panel moves, floating groups, workspace adapters and an optional egui docking surface.
