NexusInDesign 4.3.0

Changed

• The engine is compiled ahead of time (Native AOT) instead of a self-contained single-file .NET program: one native
  image that Windows maps, nothing read again from its file after it starts, so an update that replaces the engine
  while an AI session runs it can no longer break that session (NexusFree's single-file dispatcher still crashed after
  such a replacement, on an assembly loaded late that no preload had reached). Measured on the same PC (win-x64,
  median of 7 runs, MCP server 10 s after initialize and tools/list):

  	4.2.3 (single file)	4.3.0 (Native AOT)
  NexusInDesign.exe	73.6 MB	8.8 MB
  --version	42 ms	24 ms
  Start to initialize answer	224 ms	93 ms
  Working set at rest	47.8 MB	25.2 MB
  Private bytes at rest	16.0 MB	11.3 MB

• InDesign's COM automation goes through a source-generated IDispatch (ComWrappers) instead of the runtime's
  built-in COM interop and Type.InvokeMember; JSON through source-generated contexts; process and signature checks
  through LibraryImport with blittable structures. No reflection or runtime marshalling is left (IsAotCompatible,
  AOT and trim analysis clean, warnings as errors). The AOT compiler and the trimmer are pinned in
  packages.lock.json.

Added

• Test: the release build is started, its file renamed aside and replaced by other bytes the way an installer
  replaces an exe in use, and its tools (tool list, DOM index, doctor, schema validation) must still answer.

Fixed

• Tests: processes started by tests always inherit the no-error-box mode. The runtime loads each native library
  between a SetErrorMode and a restore of the previous mode, so parallel loads could leave the test process without
  SEM_NOGPFAULTERRORBOX (seen once in CI); every test now starts its processes through a helper that sets the mode
  again first, and the test checks a child started after that flag was removed.

NexusInDesign 4.2.3

Added

• Common journal of the Nexus tools (format v1): every tool call also writes one short line to
  %USERPROFILE%\.nexus\journal\indesign\<agent>\<YYYY-MM>.jsonl (agent from the verified parent or the MCP
  client; outil the engine version, issue, ms, technique the tool's route, erreur the stable error code;
  never a path, a document name or a text), so NexusSystem shows the activity of your AIs in InDesign and
  NexusJournal revue can measure failures per tool and version. A test checks the line of each call.

Fixed

• Tests: no test can show a Windows error box. The test process sets the error mode (no critical-error, crash or
  missing-file box) when it loads, and every process it starts inherits it; a test checks it in a child process.

NexusInDesign 4.2.3 (development build)

Development build of ee2903b (tests passed). Promoted as is to the stable v4.2.3 when that version is new.

NexusInDesign 4.2.2

Fixed

• A conversation opened before an update keeps working. The engine is a self-contained single-file .NET program that
  reads its own file again each time it loads an assembly; get.ps1 renamed the running engine aside and put the new
  version at its path, so the open session then read the new version's bytes and its next tool calls failed with
  "Internal error" (reproduced: search_official_dom and indesign_doctor after a replacement). Each version is now
  installed in versions\<version>-<hash>\, a folder never modified once written; current.txt names the version new
  sessions start; NexusInDesign.exe, the path the plugins start, is a small launcher compiled ahead of time (Native
  AOT, which never reads its own file again) that runs the engine current.txt names. An older version's folder is
  removed by a later run once no process runs its engine. Sessions opened before 4.2.2 still run the previous engine
  from the launcher's path and need one reconnection after this update.

NexusInDesign 4.2.1

Fixed

• get.ps1 no longer fails with "being used by another process" when a scanner briefly opens the freshly copied
  executable (the failure seen once with NexusAGYmail in NexusSystem's pack job on a fresh Windows runner). The package
  is never run before installation: its version comes from the executable's version resource, the copy staged beside
  NexusInDesign.exe is renamed into place, and only then is --version run from the installed file; if it does not
  answer the expected version, the previous executable is put back. A rename held by such an external, transient scan
  (sharing, lock or access violation) is waited out for at most 10 s; any other error still fails the installation.

NexusInDesign 4.2.0

Changed

• English by default, French on a French Windows: the MCP instructions, tool titles and descriptions
  (native/tool-contracts.json in English, native/tool-contracts.fr.json for French), results, errors and the UXP
  scripts' own messages follow the Windows display language. The doctor's registry hash stays language-neutral.
• Build output path taken from the .NET user profile instead of $(USERPROFILE), which is unset on Dependabot's Linux
  runner (NuGet restores silently failed on /.nexus).
• Strict build: recommended .NET analyzers, code style enforced, warnings as errors (.editorconfig added).
• JsonSchema.Net 9.6.0.
• Release workflow on NexusSystem's shared workflows v1.6.54, pinned by commit SHA.
• CodeQL runs from .github/workflows/codeql.yml (actions, C#, JavaScript/TypeScript, default queries) instead of the
  default setup, so OpenSSF Scorecard credits SAST for commits pushed without pull requests.
• CHANGELOG compare links for every released version.
