* photocraft-plugins: sandboxed WebAssembly filter plug-ins (wasmi host, ABI v1) A new L4 crate runs plug-ins in wasmi (pure Rust, MIT/Apache) with no host imports, a fuel budget metered in slices with a wall-clock deadline, a memory cap, a recursion cap and wasmi's strict module limits. Every band gets a fresh instance; traps, budgets, bad manifests and bad pointers are all Errors. Pixels go over as interleaved normalised f32 in tile-aligned bands, in parallel on native, blended by the selection. Includes the example Invert plug-in (no_std Rust, examples/plugins/invert-rs) built into a test fixture, hostile-module tests, and docs/plugins.md. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Engine: plugin.* commands (install, list, run, remove, reload) plugin.run filters the active pixel layer, a targeted channel or a smart object (recorded as a smart filter) as one undo step; Preferences > Plug-ins gains Use Additional Plug-ins Folder, loaded when prefs apply. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * UI: Filter > Plug-ins lists installed plug-ins with generated dialogs Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Plug-ins: bands never outgrow the memory cap; regenerate parity Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Bench: example plug-in Invert vs built-in Invert on 24 MP Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
