v0.0.0

Changelog

First tagged pre-alpha. The full crate stack under crates/ (everything except the zed-mosaic
editor extension) is published to crates.io via a resumable release workflow.

Added

• mos check: parse, lower, and resolve a .mos file or project directory, emitting
  source-anchored diagnostics with stable MOS#### codes, carets, UTF-8-accurate columns, and
  CRLF-aware spans. The CLI applies phase-barrier fail-fast (each phase runs to completion, then
  exits if any error was collected) and gates PDF emission on diagnostic severity.
• mos build: render a document to PDF under build/<entry-stem>.pdf, or to a project-declared
  [output].pdf path. Built PDFs open automatically after a successful build.
• CLI accepts both single .mos files and project directories.
• Markup parser: headings, paragraphs, inline emphasis / strong / nested bold-italic, inline and
  multiline code spans, raw code blocks (including long-bracket form with literal bodies and
  preserved tabs and escapes), unordered (-) and ordered (N.) lists with hanging indent, #set,
  #image, #figure, and cross-reference labels / references.
• Semantic lowering and resolution: a Document model with metadata, automatic hierarchical section
  numbering, a cross-reference resolver, and duplicate / unknown-label diagnostics.
• Layout engine: greedy text flow; headings, paragraphs, and lists (with adaptive gutters and
  per-marker shaping for ordered lists); raster images and simple figures with captions; pages,
  paper sizes, and margins; #set page / text / document properties wired into layout and PDF
  metadata; NFC text normalization; and oversized-word breaking on shaped glyph clusters.
• Fonts: a zero-dependency Adobe Font Metrics (AFM v4.x) parser; Base-14 metrics; per-glyph font
  fallback; and bundled, subsetted Noto Sans, Noto Sans Mono, and Noto Sans Math for broad Unicode
  coverage beyond the Base-14 cliff.
• PDF backend: WinAnsi plus Latin-Extended text via per-document /Differences and /ToUnicode,
  Type 0 CID emission for embedded fonts, GPOS-positioned glyph output, PNG and JPEG image XObjects,
  title / author Info metadata, and deterministic object / font / image emission order.
• Editor tooling: a Tree-sitter grammar and corpus (tree-sitter-mosaic) and a Zed extension
  (zed-mosaic) providing highlighting, outline, document runnables, and semantic-token defaults.
• An in-memory cache foundation (mos-cache) backed by a HashMap.
