v0.4.0

Upgrading from 0.3.x needs nothing: the index schema is unchanged at version 3,
so an existing .asset-memory/index.db is read as-is. Upgrading from 0.2.x
requires a reindex from schema 2, which the indexer performs automatically on
the next run — no flag and no manual migration.

Two changes are worth knowing before upgrading: the web viewer served at / is
the new one, with the previous viewer moved to /legacy.html; and
search_assets now matches an asset's path and GUID prefix as well as its name,
so the same query returns more results than in 0.3.2.

Added

• Interactive web viewer. A new graph viewer served at /, rendering the
  dependency graph in three modes: 2D, DAG, and 3D. 2D and DAG are
  drawn as inline SVG; 3D uses three.js and loads on demand. Includes an
  attention panel for broken references, unused assets, and the most-referenced
  assets; filters by asset type and origin; dependency/reference tracing; a node
  budget for large graphs; search; back/forward navigation; and light/dark
  theming.
• Five HTTP API endpoints: /api/asset-detail, /api/broken-references,
  /api/graph, /api/index-status, and /api/root-trace.
• --concurrency <n> on the indexer, to tune scanning and extraction for a
  given machine or storage device.
• --project <root> on the web viewer, matching the argument the MCP server
  and indexer already take.
• Project discovery. Run the web viewer from anywhere inside a Unity project
  and it locates the project root by walking up, the way git finds a
  repository. No arguments are required.
• Automatic port selection. The viewer binds the first free port from 7777,
  so several projects can be served at once without configuration.
• Cross-platform installers — scripts/install.sh and scripts/install.ps1,
  with Node version preflight and --package, --force, and --dry-run.
• Unity Editor package downloads on the GitHub release page, in three
  installable formats: .tgz (Package Manager → Add package from tarball),
  .zip (Add package from disk), and .unitypackage (Assets → Import Package).
• Server-less viewer download — asset-graph-viewer-static-<version>.zip,
  the WASM SQLite viewer that runs from the filesystem with no server.

Changed

• The new viewer is served at /. The previous Cytoscape viewer remains
  bundled and moves to /legacy.html.
• search_assets matches more. The name filter now matches an asset's
  name, path, or GUID prefix; it previously matched only the name. Affects the
  MCP tool and the web API alike, and returns strictly more results than 0.3.2
  for the same query.
• Indexing runs in parallel. Scanning and reference extraction use bounded
  concurrency; SQLite writes remain transactional and serialized. Output is
  unchanged — a full index at concurrency 1 and 8 produces byte-identical
  assets and edges tables.
• Installs are much smaller. Viewer build dependencies are no longer runtime
  dependencies, and only latin/latin-ext WOFF2 fonts are bundled. A production
  install drops from roughly 134 MB to about 40 MB, and the published package
  from 1.45 MB to 0.72 MB.

Removed

• The WASM SQLite viewer is no longer inside the npm package. It is a
  separate download on the release page. It exists to be opened from the
  filesystem, so it was charging every install about 706 KB of WASM it would
  never load. Nothing about the flavor itself changed.

Fixed

• The web viewer no longer dies with an unhandled EADDRINUSE when its port is
  taken; it selects the next free port instead.
• --concurrency no longer silently ignores a non-numeric value, and
  --concurrency --force no longer consumes --force as its value.
• AsyncLimiter hands a released slot directly to the next waiter, closing a
  window in which two tasks could briefly exceed the configured limit.
• The attention panel renders its results, and 3D graph rendering is no longer
  too dark to read.
• The installers' PATH hint used npm bin -g, removed in npm 9 and therefore
  failing on every supported Node version. It now uses npm prefix -g.
• Fonts are served as font/woff2 rather than application/octet-stream.

Notes

• The MCP tool surface is unchanged at 15 tools. The search_assets behavior
  change above is the only difference an MCP client will observe.
• The Unity Editor package is versioned independently and remains at 0.2.0; it
  is unchanged in this release.

v0.3.0 — Addressables Discovery

What's changed

• Added fast, read-only Addressables discovery with normalized groups, entries, addresses, labels, and read-only state.
• Added MCP tools: get_addressable_info, search_addressables, and list_addressable_groups.
• Kept Addressable entries as conservative roots for unused-asset analysis and added reachableOnlyBecauseAddressable as a review signal.
• Added deterministic schema 3 JSON/snapshot output and explicit stale-index rebuild guidance.
• Hardened parsing against package test fixtures and unrelated lookalike assets.

Upgrade note

Rebuild existing .asset-memory/index.db files after upgrading. Schema 2 indexes are not migrated in place.

Verification

229 tests passed, plus typecheck/build/package smoke and a real-project run covering 18 groups and 2,971 Addressable entries.
