Unrelated to the security changes in this branch; `main` already failed
`clippy --workspace --all-targets -- -D warnings` without them. Eight
clippy::nonminimal_bool sites across seven files, each taking clippy's own
suggested rewrite.
Every rewrite is pure boolean algebra with the negation kept outside, so the
float comparisons and their NaN behaviour are untouched: !A && !B becomes
!(A || B), and !opt.is_some_and(f) becomes opt.is_none_or(!f). Two sites needed
explicit parentheses the suggestion omitted, where the rewritten term is the left
operand of an && and || binds looser.
designcraft cleared the same lint in bc840130; this is figcraft's equivalent.
A document carries things the app acts on for whoever opens it. Three of them were
taken as given.
Prototype Open link and Dev Mode dev resources both reached the platform's opener
with any scheme. In the web build the opener is window.open, so a saved document
could run script in the app's own origin; on the desktop any scheme went to the
system's handler. Both now pass through the new engine module `doc_urls`, which
allows http, https and mailto and nothing else. It is an allow-list on purpose: a
list of known-bad schemes is outgrown by every handler a platform adds.
A figcraft:// invite link joined the session at once. The system hands the app
whatever such link was followed, which may come from a page or a message, so the
Join dialog now opens with the link filled in and the person confirms.
A library link stored in a document was loaded from wherever it pointed. Only a
path on this computer is followed now, so opening someone else's file cannot make
the app contact their server (which on Windows would also send credentials).
Tests: each change has one that fails without it, verified by reverting. The
prototype test fires through an afterDelay trigger, since no click is needed, and
keeps a positive case so a refusal cannot pass vacuously.
Escape or Enter while the pen draws ends the path and keeps its vector in
edit mode with the pen, so the next path joins the same layer; another
Escape leaves edit mode. Entering edit mode on a layer that already is a
vector no longer records an empty undo step.
- `figcraft-cli mcp --automation-read-root DIR --automation-write-root DIR` (each repeatable, `--flag=DIR` works too). When either is given, every file an agent's tool call reads must lie inside a read root or a write root, and every file it writes inside a write root. Anything else is an ordinary tool error (`automation path rejected: … is outside the folders that may be written: …`); nothing is written and the server keeps serving. Without the flags nothing changes.
- The desktop app takes the same flags (`figcraft --control PORT --automation-read-root DIR …`) and confines every control request and every frame of every window to them, so `figcraft-cli mcp --attach` drives a confined app. `--attach` together with the flags is a usage error, because the app runs the commands and only the app can confine them.
- New engine module `crates/engine/src/file_access.rs`: `Roots` (resolution and comparison), a thread-scoped `confined(roots, f)`, and the file primitives (`read`, `read_capped`, `open`, `metadata`, `read_dir`, `write` (atomic), `create_dir_all`, `exists`, `is_dir`). Every engine file access now goes through it. `crates/engine/clippy.toml` denies `std::fs::*`, `File::open/create`, `OpenOptions::open`, `Path::exists/is_file/is_dir/metadata/read_dir/canonicalize` and `figcraft_format::{write_file_atomic, save_file, load_file}` everywhere else in the engine, so a command added later is confined without a check of its own.
- `ui.screenshot` and `ui.render` return the PNG as base64 `data` when no `path` is given (before, `ui.screenshot` wrote `figcraft-screenshot.png` in the working directory and `ui.render` required a path). The attached MCP backend uses that, so it no longer writes and deletes temporary PNGs, and a confined app needs no exemption for them.
- `initialize`'s `instructions` name the folders the agent may read and write.
- `figcraft-cli` options may be given more than once (`Args::values`); single-valued options keep the last value, as before.
- Docs: `docs/mcp.md` › Confining file access (options, semantics, coverage, resolution, limits), `docs/control-protocol.md` › Confining file access and the optional `path` of `ui.screenshot` / `ui.render`, `docs/cli.md`, `figcraft-cli --help`, and the Automation line plus a revision row in `docs/target-app-parity.md`.
Fixes#715, fixes#481.
A layer inside an instance can now override its resizing (hug, fill or
fixed, with min and max sizes; override group `resizing`) and its size.
They were refused, and imported ones were dropped at the first relayout.
Kept through rebuilds, undo, save, .fig and REST import, .fig export and
detach; reset per group and with Reset all changes. Position, constraints
and absolute or grid placement stay the main's.
