v1.0.64

[1.0.64] - 2026-05-28

Fixed

• BUG-1 HIGH: ingest --mode claude-code now disables hooks via --settings '{"hooks":{}}' for OAuth users and detects terminal_reason: "max_turns" — prevents Stop hooks from consuming extraction turns (was failing 65% of files for users with hooks configured)
• BUG-2 HIGH: ingest --mode claude-code now detects OAuth via apiKeySource from Claude Code init JSON and omits misleading cost_usd from NDJSON output — --max-cost-usd budget cap is ignored with warning for subscription users who are not billed per API call
• BUG-3 HIGH: ingest --mode claude-code and --mode codex now validate body size BEFORE sending to LLM subprocess — files exceeding 512 KB body cap are skipped with actionable warning instead of wasting LLM tokens on extraction that will be discarded
• rename and rename-entity now reject same-name renames with exit 1 (Validation) — prevents version inflation, unnecessary FTS5 sync, and wasted re-embedding

Added

• deep-research command for parallel multi-hop GraphRAG research via heuristic query decomposition (up to 7 sub-queries), bounded fan-out with tokio::task::JoinSet and Arc<Semaphore>, 3-hop graph traversal, evidence chain assembly, and per-sub-query timeout — defaults calibrated against NovelHopQA, StepChain, HopRAG, and GraphRAG-Bench benchmarks (k=20, max-hops=3, max-sub-queries=7)
