* fix: disable headless fallback by default
Persistent mode silently fell back to running CODESYS with --noUI
whenever the launch refused (e.g. another GUI instance was already
running). That left the user staring at no window while the MCP
spawned hidden processes per command. Flip the default of
--fallback-headless to false so the MCP errors out loudly instead;
opt in explicitly if silent --noUI is actually wanted.

* fix: clear stale lastError on launch retry and successful ready
get_codesys_status kept reporting historical "Last Error: Refusing
to launch..." messages forever because lastError was set on failure
but never reset. Reset to null at the top of launch() so a retry
starts clean, and again when the watcher signals ready so a
successful re-launch wipes prior errors.

* release: v0.9.2 -- no headless fallback by default + clear stale lastError

Project rename. The 'SP21+' identifier is more accurate than the
previous 'SP22+' label -- this fork specifically carries the SP21+
migration fixes (the upstream's system.execute_on_primary_thread()
removal and downstream API drift), and is forward-compat with later
SPs. The repo on GitHub has been renamed to
phobicdotno/Codesys-MCP-SP21-plus accordingly.
Substitutions (UTF-8 preserved this time -- prior PowerShell pass
mangled em-dashes via a Win-1252 round-trip):
- package.json: name codesys-mcp-sp22-plus -> codesys-mcp-sp21-plus,
bin entry, repository.url, homepage, description, author trailer
- README.md: title, banner, install + clone snippets, CLI invocations
- ARCHITECTURE.md: comparison-table column header + temp-dir prefix
- tests/TEST_OVERVIEW.md: title
- src/bin.ts: header comment + program().name()
- src/launcher.ts: SESSION_DIR_PREFIX
- src/types.ts: header comment
Compatibility phrase 'Works on SP19, SP21, and SP22+' and the technical
identifier 'SP22 Patch 1 fixes' (which name the actual CODESYS version)
were preserved -- those refer to CODESYS, not the project name.
README additions:
- Quick Start example switched from SP21 Patch 3 to SP22 Patch 1 to
match the more common modern install
- New 'Multiple CODESYS installations' subsection with worked
side-by-side example for SP21 (3.5.21.50) and SP22 (3.5.22.10) --
one named MCP server entry per install, called by name from Claude.
Documents the constraint that --codesys-path/--codesys-profile are
bound at server startup, that --detect lists installs, and that
config edits require a Claude Code restart
- Tool count corrected from 28 -> 37 in the Features bullets
- New Tools sections covering 10 previously-undocumented tools:
Version Anchor + Release Pipeline (bump_project_version,
release_project_version, read_running_version_online), Source
Mirror (mirror_export), and CODESYS Git PDE-gated (git_init,
git_status, git_commit, git_remote_add, git_branch_set_upstream_to,
git_push). Each row carries the actual operational gotchas
discovered during this session (UNC localRepoPath rejection,
push-without-upstream failure, optimizer stripping unreferenced
globals from the online symbol table, etc.)
- list_project_libraries + add_library row text updated to reflect
the post-fix behaviour (compiler-version capture; managed-overload
preference + resolution gate)
Local origin URL updated: phobicdotno/Codesys-MCP -> phobicdotno/Codesys-MCP-SP21-plus.
37/37 tests green.
Project identity rename. Concrete changes:
- package.json
- name: codesys-mcp-persistent -> codesys-mcp-sp22-plus (npm-safe;
'+' is not allowed in npm package names)
- description: prepended 'Codesys-MCP-SP22+' branding + brief
summary of the SP22+ fixes carried in this fork
- bin entry: codesys-mcp-persistent -> codesys-mcp-sp22-plus
- repository.url + homepage: now point at
github.com/phobicdotno/Codesys-MCP-SP22-plus (using -plus
spelling on the URL side; '+' would require URL-encoding)
- author: noted upstream + SP22+ fork attribution
- README.md: title + about-this-fork blurb + clone instructions
- tests/TEST_OVERVIEW.md: title
- ARCHITECTURE.md: comparison-table column header + temp-dir path
- src/bin.ts: file header + program().name()
- src/launcher.ts: SESSION_DIR_PREFIX (with note on backwards compat)
- src/types.ts: file header
Display name everywhere: 'Codesys-MCP-SP22+'.
npm package name: 'codesys-mcp-sp22-plus'.
Out of scope for this commit -- need user action:
- Local directory rename (C:/Users/karstein.kvistad/Codesys-MCP ->
...-SP22+) cannot be done while the persistent MCP is using dist/
from the current path; user can rename after shutting down VS Code.
- GitHub repo rename (phobicdotno/Codesys-MCP -> ...-SP22-plus or
...-SP22+) needs the github.com web UI; the package.json URLs
already point at the post-rename name so a 'git remote set-url
origin <new>' lines up after.
- MCP client config in .mcp.json or similar: the bin name changed
from 'codesys-mcp-persistent' to 'codesys-mcp-sp22-plus' -- update
any 'command' field that referenced the old name. (Local sessions
invoking node dist/bin.js directly are unaffected.)
37/37 tests still green after rename.
v0.3.0 returning-watcher architecture — background thread polls for commands
and marshals execution onto the CODESYS UI thread, keeping the IDE fully
responsive between operations. File-based IPC with atomic writes, async mutex
command serialization, headless fallback, and 35 passing tests.
