v0.1.3

The first release that pairs the published gem with the interactive viewer the README has been showcasing, plus the supply-chain hardening that justifies shipping a vendored third-party JS file inside the gem.

Added

• Interactive view --output html viewer. Replaces the static Mermaid embed with a Cytoscape.js-based page that renders 5k+ nodes, filters live by kind / confidence, supports a name-substring search, and copies path:line to the clipboard on node click. The Cytoscape library is vendored into the gem at a sha256-pinned version (lib/rigor/module_graph/templates/vendor/cytoscape.min.js); no CDN, no npm, no Dependabot auto-bump. See docs/plan.md "2D interactive viewer" for the supply-chain rationale.
• --path-mode {relative,absolute,none} flag on view — controls how node paths reach the viewer's click-through metadata. none strips paths from the HTML artefact, which is the right setting when sharing the file outside the project (PR comment, gist, …).
• --open-with vscode flag on view — flips the node-click action from clipboard copy to vscode://file/<path>:<line> so the editor jumps straight to the source location.
• bundle exec rake vendor:verify task — recomputes sha256 for every file in vendor/CHECKSUMS and fails on mismatch. Wired into pre-commit on any staged file under lib/**/templates/vendor/**.
• .github/dependabot.yml — weekly Bundler + GitHub Actions bumps; vendor/** is explicitly excluded so vendored third-party JS never auto-updates.
• bundle exec rake vendor:audit — 4-source cross-check (local sha256 / npm tarball dist.integrity / tarball-internal copy / GitHub raw / every CDN). Reads lib/rigor/module_graph/templates/vendor/MANIFEST.yml for the provenance metadata. Use on bump PRs; not part of the regular CI pipeline (network-using).
• CI now runs rake vendor:verify independently of pre-commit so an unaudited bump can't land on main even if local hooks were skipped.
• CI now regenerates examples/billing/ via script/ check_billing_drift.rb and fails on drift between the freshly-built artefacts and the committed copies. Normalises the graphviz version banner so the runner's apt-shipped version doesn't trigger a false positive.
• New docs/security.md consolidates the supply-chain story (Bundler / Dependabot cooldown, vendored-JS sha256 + 4-source audit, action SHA pinning, OIDC trusted publishing).

Changed

• view --output html semantics. The flag now produces the interactive viewer. The previous static Mermaid HTML moves behind --output mermaid-html (still loads Mermaid from a CDN, kept for back-compat).
• CI workflows read Ruby from .ruby-version instead of pinning "4.0.0" inline, so future .ruby-version bumps no longer need a .github/workflows/ chase.
• RDoc dependency bumped from ~> 6.0 to ~> 7.0 (resolves to 7.2.0). gemspec.rdoc_options corrected to --markup markdown to match .rdoc_options and the Rakefile, fixing the silent inconsistency left when the README rendering fix landed in [0.1.2]. No code change; rake rdoc emits no warnings under 7.x.
• README hero leads with the Cytoscape viewer screenshot (the default output) and the Graphviz SVG follows. examples/billing/preview.png resized from 1280x860 to 720x483 so it fits the RDoc darkfish content pane on the GitHub Pages site without overflow.
• README Documentation index re-ordered along the natural reading flow: how-it-works → security → limitation → development → plan.

v0.1.2

First release that exercises the full automated pipeline end to end — Trusted Publishing + GitHub Release + asset upload all drive off a single gh workflow run release.yml after the tag is pushed.

Added

• view and collect now emit step-level progress on stderr: ==> Running rigor check ..., post-step counts (18 edge(s), 16 node(s)), and inline elapsed time (done (428ms)). TTY-aware — the start / done halves render inline on a terminal, on separate lines for redirected output, so logs stay grep-friendly. -q / --quiet suppresses the progress output for scripted use; the final wrote N edge(s) to ... summary line stays. Driven by a new StatusReporter class pinned by test/rigor/module_graph/status_reporter_test.rb.

Changed

• README restructured along the install → getting started → usage → configuration flow. The "How it works" walkthrough (pipeline diagram + the "not a call graph" framing) moves to docs/how-it-works.md so the README stays focused on "what do I type". Configuration section now notes that .rigor.yml is required (rigor reads it to discover the plugin), with a two-line minimum example up top and the fully-elaborated default form below.

Fixed

• RDoc generation now parses Markdown instead of RDoc syntax, so ![alt](path) images in README.md / CHANGELOG.md / docs/*.md actually render. Rake::Task[:rdoc] is enhanced to copy examples/billing/graph.svg (and any future RDOC_ASSET_PATHS entries) into doc/ so the generated site resolves the relative image references the README uses.

v0.1.1

First Action-driven publish. The 0.1.0 release happened via the CLI fallback before the rubygems.org Trusted Publisher registration was in place; 0.1.1 is the first version to land through release.yml.

The user-visible code surface is intentionally tiny: the major correctness fix (namespaced association resolution), the Stats / Reachability / Edge perf rewrites, the SHA-pinned workflows, the docs split, and the MIT LICENSE.txt all already shipped in 0.1.0.

Changed

• --version / -v / version now prints rigor-module-graph X.Y.Z instead of a bare X.Y.Z. Matches the convention bundler --version and gh --version use; bug reports pasted into chat are self-identifying.

v0.1.0

Initial release. Baseline shipping everything from the Phase 0 spike through Phase 5 (UML class diagram).

Added

• Phase 0: Rigor plugin API spike against rigortype 0.2.1
  • rbs ~> 4.0, validating that node_rule(Prism::ClassNode) and friends work and locking in the :info diagnostic output channel.
• Phase 1 (MVP): extraction of inherits / include / prepend / extend edges. Rigor::ModuleGraph::Edge (a Data subclass) with a JSONL writer, Graphviz DOT and Mermaid flowchart renderers, and cycle detection via an iterative Tarjan SCC.
• Phase 2: Zeitwerk-style path → constant inference (ZeitwerkResolver), namespace collapse in both renderers (DOT subgraph cluster_* and Mermaid subgraph), and const_ref edges from constant references inside method bodies (gated on include_constant_refs). Confidence promotes from syntax → zeitwerk when the path-inferred name agrees with the lexical owner.
• Phase 3: indirect mixin resolution via scope.type_of. A Rigor::Type::Singleton carrier lifts the edge to confidence: "rigor_type"; everything else degrades to "unresolved" with the source slice preserved in raw. CLI gains --kind and --confidence filters.
• Phase 4: stats subcommand reporting per-namespace fan-in / fan-out / internal / nodes (text and JSON, with --grouping-depth N and --limit N). Packwerk overlay (--package / --package-root PATH) discovers package.yml files recursively and uses them as the cluster boundary. The Dot / Mermaid renderers accept an explicit groups: mapping for arbitrary node → cluster assignments.
• Phase 5: UML-style class diagram. collect writes a sibling nodes.jsonl covering class / module declarations, method definitions, and attr_* attributes — with visibility tracked via the VisibilityMap's bare private / protected / public keyword walk. Rails associations land as edges (has_many / belongs_to / has_one / has_and_belongs_to_many, with cardinality and a tiny Rails-style inflector that maps :invoices → Invoice). A new Uml::ClassDiagram renderer and class-diagram subcommand emit Mermaid classDiagram syntax; filters --no-methods, --no-attributes, --public-only, --no-private.
• view one-shot subcommand: rigor-module-graph with no args (or view explicitly) analyses the current directory, writes a self-contained HTML report under .rigor/module_graph/, and opens it in a browser. The --output html|mermaid|dot|svg|class-diagram flag switches format; non-html streams to stdout unless -o PATH is given.
• Reachability filter (--from NAMES, --depth N, --direction in/out/both) shared by every reader subcommand. Subsequent --edge-scope cluster|walk flag distinguishes "show the neighbourhood as a cluster" (default) from "show only the edges the BFS actually traversed" (Codex review confirmed naming and direction-both semantics).
• Billing example (examples/billing/): Customer / Invoice / Payment / LineItem + concerns. build.rb runs the same view --output pipeline that ships in the CLI, and commits index.html, class-diagram.html, graph.svg, and a preview.png so the GitHub view of the repo shows the rendered output directly.
• RDoc support via rake rdoc / rake rdoc:preview / rake rdoc:server.
• minitest + minitest-snapshot test harness. Snapshots refresh with UPDATE_SNAPSHOTS=1 rake test.
• SimpleCov C2 (branch) coverage measurement via COVERAGE=1 rake test or rake coverage. Baseline is 91.19% branch coverage (445 / 488 branches).
• lefthook wiring rubocop / betterleaks / rigor / zizmor on pre-commit and minitest on pre-push.
• GitHub Actions: ci.yml (test, lint, workflow-lint) and release.yml (workflow_dispatch-only, uses RubyGems trusted publishing — no long-lived API token).

Performance

• Stats.compute rewritten as a single pass with a mutable per-namespace counter array instead of a Data#with cascade per edge. On 2016 edges this took the call from 139 ms to 47 ms (3.0×).
• Reachability.walk swaps Set for Hash<name, true> + Array frontier, builds only the adjacency direction it actually needs, and the :both-direction walked_edge_indexes shares one pair of indexed adjacencies between its out-walk and in-walk. Cluster depth-3 outbound: 27 ms → 14 ms (1.9×); both direction: 35 ms → 19 ms (1.8×).
• Edge#dedup_key is now a generated Data member set once in Edge.build as a --frozen joined string. Renderer dedup Hashes go from Hash<Array,_> to Hash<String,_>, which drove the 1.2× Dot / Mermaid render gain.
• YJIT (--yjit) adds another ~1.5×. ZJIT measured between baseline and YJIT, and trailed baseline on Stats and CycleDetector — recommendation stays YJIT.
