Veqtor v0.3.0 Alpha

This file is the promotion payload, not evidence that v0.3.0 is public.
Publication is established only by the immutable GitHub Release metadata and
its exact verified assets.

Veqtor v0.3.0 is a community-supported technical Alpha focused on verifiable
local contract-review workflows and easier activation in Claude Desktop for
macOS.

Highlights:

• the eight-tool MCP surface adds bounded inspect_document views over a
  mechanical accepted/current main-body projection and seed-centred
  map_rounds evidence maps;
• Round Map reports complete exact paragraph equality, explicit
  unresolved/ambiguous states and recorded document-byte derivations without
  claiming chronology, paragraph lineage, legal effect or authorship;
• decision-record locking, full-frame writes and rollback are hardened for
  bounded cross-thread/process contention, partial writes, storage failure and
  workspace-path replacement;
• a versioned macOS Claude Desktop Extension (.mcpb) with explicit
  tracked-change-author configuration, all eight tools, a deterministic
  four-round demo and a ready-to-run inspection/map prompt;
• the proof-bound preflight/apply flow detects changes to the source, edit
  request, author or predicted output between the two calls;
• reproducible wheel, source archive and MCPB builds. SHA256SUMS.txt binds all
  three release payloads; the checksum is an integrity check, not a digital
  signature.

The first extension activation may download a compatible Python runtime and
the dependencies pinned in uv.lock through Claude Desktop's UV runtime. The
extension is a macOS activation path; version-pinned uvx and uv tool install remain available for supported command-line installations.

To install in Claude Desktop, download and open
veqtor-mcp-0.3.0-macos.mcpb, approve the extension, and enter the name that
Word should show as the author of new tracked changes. Then run the bundled
try_veqtor_demo prompt.

For an optional advanced integrity check, compare the output of
shasum -a 256 veqtor-mcp-0.3.0-macos.mcpb with its entry in
SHA256SUMS.txt. The MCPB is not digitally signed. Because this is the first
public MCPB, there is no older extension to roll back to; this release tests
clean install, uninstall, post-uninstall tool absence and same-artifact
reinstall. Real upgrade and rollback become release gates for the next MCPB.

Veqtor remains a local technical Alpha. It is not legal advice, a hosted
service, a full Word editor, a chronology/lineage proof system or a
tamper-evident audit log. Review the
known limitations
before using it on a real matter.
