For LongMemEval-style benchmarks that add hundreds of memories per instance, this collapses ~13 min/instance (one subprocess per entry) to seconds. ## Implementation - `BatchMemoryEntry` struct with `text`, `scope`, `kind`, `valid_from`, `valid_to` (temporal fields optional, `#[serde(default)]`-compatible). - `add_memory_inner()` — private per-entry core factored out of `add_memory`. Shared by both paths; zero logic duplication. Carries redaction, dedup, event emission, temporal stamping, embed_and_persist, rarity bonus, and conflict detection. - `add_memories_batch(start, entries)` — opens project + resolves embedder ONCE, acquires lock ONCE, loops `add_memory_inner` for each entry. GlobalUser entries route to the user brain (same as single-add); fallback to project DB when user brain is disabled. - CLI: `add-batch ` reads JSONL or JSON-array; `-` reads stdin. `--scope` / `--kind` flags set defaults overridable per entry. `--json` emits `{added: N, ids: [...]}`. ## Tests (3 new) - `add_memories_batch_present_retrievable_rebuild_safe`: 5 entries present, all ids returned, embedding_model consistent with single-add, survive `rebuild_in_place`, temporal bounds (valid_from/valid_to) round-trip through rebuild. - `add_memories_batch_deduplicates`: same text twice returns same id, one DB row. - `add_memories_batch_all_entries_same_embedding_model`: 8 entries all share the same `embedding_model` value (null in lean build, real model id in embeddings build) — structural proof that the embedder is loaded once.

Per "prove first, surface after", graph stays internal — NOT wired into retrieval levels. #7 — Calibration scaled to release-grade (bench, local-only): - calibration_gen dataset directive synthesizes ~100 deterministic cite/regret scenarios from the corpus + ~22 curated anchors; scorecard gains per-dimension n + 95% CI. Measured: 122 cases -> 99.7% +/- 0.3%. fix(cli): retrieval-level override (pre-existing). `config set` of a level-managed key (embedder.enabled/reranker) under a preset now drops retrieval.level to "custom" so the explicit value survives apply_retrieval_level at load.

Write-safety already came from Slice A (per-request connection + IMMEDIATE txns); the gap was per-user attribution on a multi-user server. - Thread-local origin override (kimetsu-core/event.rs): OriginScope RAII guard; process_origin() prefers the thread-local. Each remote request runs on ONE spawn_blocking thread, so the per-request override is visible to Event::new and cleared on return (tokio reuses blocking threads). - Token -> user identity (auth.rs): AuthConfig.token_names + user_for_token (configured name else a stable non-secret anon-); tokens-file gains a [names] table (back-compat). - Server attribution (lib/state/rpc): `serve --node ` sets the HLC node once at startup; dispatch_request wraps the blocking dispatch in OriginScope("/user:"). - CLI write-to-remote (kimetsu-cli/remote_client.rs + main.rs): `kimetsu brain memory add --remote --repo [--token | KIMETSU_REMOTE_TOKEN]` posts a JSON-RPC tools/call via reqwest. - Metric: aggregate, unlabeled kimetsu_remote_memory_writes_total (the /metrics endpoint is intentionally unauthenticated -> no repo/user labels). Proof: OriginScope / user_for_token / remote_client unit tests; a remote integration test asserting the brain event origin == "remote/user:webuser"; E2E (boot serve --node srv1, CLI memory add --remote -> event origin "srv1/user:alice", hlc node srv1, memory_writes_total 1). Completes the #3 epic (A+B in 6061341). Gate: fmt; clippy lean + --features embeddings + -p kimetsu-remote (-D warnings); kimetsu-core 45, kimetsu-cli 243 + cli_smoke 10, kimetsu-remote 33 + integration suites pass.
