Please deep think / ultrathink as this is a nuanced search and exploration task.

code-concept-search-v2

Find a concept in the codebase — a pattern, a capability, a component, a method — even when the codebase names it something completely different from what you expect. Returns factual findings with provenance (which plan created it, who modified it, why it exists) so callers can make informed reuse decisions.

V2 Enhancement: Scans domain § Concepts tables first for near-instant discovery before falling through to code-level search. Domain Concepts are a structured capability index — if a domain documents a concept, we find it in seconds, not minutes.

Key Characteristics:

• Domain-Concepts-first — scans docs/domains/*/domain.md § Concepts tables as Tier 0
• IS the worker (does NOT launch subagents)
• FlowSpace-first with multi-tier fallback
• Walks the codebase like a human engineer when FlowSpace is unavailable — reads, follows flows, reasons about what's related
• Provenance-aware — traces each finding back through plans, execution logs, and git history
• Concise output — all the facts, no filler
