+# B-0353 — Kenji-era research docs cross-reference audit
+
+**Priority:** P1
+**Parent:** B-0139
+**Filed:** 2026-05-14
+**Filed by:** Lior
+
+## What
+
+This is a decomposed slice of the B-0139 blob (Pre-substrate Kenji-era Otto-lineage work inventory). It handles specifically the `docs/research/` cross-reference sub-scope:
+
+"Pre-substrate research docs under `docs/research/` that aren't yet in `MEMORY.md` or referenced from substrate-class memory files."
+
+## Acceptance Criteria
+
+1. **`docs/research/` cross-reference**: Every file under `docs/research/` is either indexed in `MEMORY.md` or has explicit "research-grade unindexed" rationale.
+2. Provide a report of the findings and update `MEMORY.md` where appropriate.
