Clears false positives on valid .mcp.json (gap matrix, Batch 1):
- ${CLAUDE_PROJECT_DIR} is auto-injected at runtime (CC 2.1.139) and never
needs an env block — now allowlisted.
- POSIX expansions like ${VAR%pattern} / ${VAR:-default} are resolved by
Claude Code (CC 2.1.142); the env-var regex now matches only bare
${IDENTIFIER}, so operator expressions are skipped.
Genuine bare unreferenced vars are still flagged (broken-project regression
intact). The MCP `trust` field is untouched — it is verify-first (point 4),
not part of Batch 1.
Tests: hermetic runtime temp-fixture; 23/23 MCP green, both directions covered.

Add /ultraresearch-local for structured research combining local codebase
analysis with external knowledge via parallel agent swarms. Produces research
briefs with triangulation, confidence ratings, and source quality assessment.
New command: /ultraresearch-local with modes --quick, --local, --external, --fg.
New agents: research-orchestrator (opus), docs-researcher, community-researcher,
security-researcher, contrarian-researcher, gemini-bridge (all sonnet).
New template: research-brief-template.md.
Integration: --research flag in /ultraplan-local accepts pre-built research
briefs (up to 3), enriches the interview and exploration phases. Planning
orchestrator cross-references brief findings during synthesis.
Design principle: Context Engineering — right information to right agent at
right time. Research briefs are structured artifacts in the pipeline:
ultraresearch → brief → ultraplan --research → plan → ultraexecute.
