This commit introduces a new test suite for the _canonicalUri function, ensuring its behavior aligns with expected properties such as idempotency, proper handling of Windows drive letters, and tolerance for non-URI strings. The tests cover various scenarios, including empty input, backslash handling, and percent-decoded path segments, to maintain robustness and prevent regressions.

this shouldn't be here - platformos-check already has the concept of fixers

this shouldn't be here - this belongs to platformos-check (and it is already there - we mark deprecated tags in the platformOS engine repo, based on which we generate API reference documentation, based on which platformos-check knows, which tags are deprecated)

Adds a new monorepo workspace package — @platformos/platformos-mcp-supervisor — that ports the validate_code surface of the external pos-supervisor project into platformos-tools as a
TypeScript-first, single-tool MCP server speaking stdio.
The supervisor wraps @platformos/platformos-language-server-node in-process (no pos-cli subprocess, no PATH dependency) and layers platformOS-specific structural checks, enrichment, fix
generation, schema/translation validators, a 15-step diagnostic pipeline, and a 32-module rule engine on top.
v1 ships exactly one MCP tool: validate_code. Eight other tools from the source repo (validate_intent, scaffold, project_map, analyze_project, lookup, domain_guide (tool), module_info,
enrich_error, server_status, load_development_guide), the analytics / CAC / case-base / promoted-rules / dashboard / HTTP transport / session-event-bus / blob-store / fs-watcher
subsystems, and pending-state suppression (pending_files/pending_pages/pending_translations) are deferred. The deferred surface is enumerated in
docs/mcp-supervisor/decisions/001-package/README.md with mitigation strategies per item.
What's in this PR
Architecture (one-liner)
agent → stdio (JSON-RPC) → McpServer → validate_code handler
↓
parse (liquid-html-parser) → in-process LSP (PassThrough + protocol)
→ enrich (rule engine + regex fallback)
→ 15-step diagnostic pipeline (suppress / verify / stamp)
→ schema / translation / GraphQL validators
→ structural warnings (16 detectors)
→ diff-aware (RemovedRender / AddedParam)
→ domain guide → fix generator → cluster + scorecard
→ bridge rules → stamp defaults → force-disable filter
→ ValidateCodeResult (JSON)
