+## 2026-02-16 - US-005
+- Populated navprove-tutanota-search-001 with content (reference patch, Dockerfile, instruction.md)
+- Files changed:
+  - benchmarks/ccb_navprove/navprove-tutanota-search-001/tests/reference_fix.patch (22682 bytes, extracted from source config.json)
+  - benchmarks/ccb_navprove/navprove-tutanota-search-001/environment/Dockerfile (uses tutanota base image + /workspace symlink)
+  - benchmarks/ccb_navprove/navprove-tutanota-search-001/instruction.md (symptom-only description of mail decryption failure)
+- Source bug: Owner-encrypted session key not propagated through entity loading chain (EntityClient → cache → REST client). Non-legacy mails using new permission model fail to decrypt MailDetailsBlob/MailDetailsDraft entities.
+- 9 files changed in patch, but core issue is the load/loadMultiple API needing a new providedOwnerEncSessionKey parameter
+- Failing tests: test_2954, test_2955 (from Suite.js)
+- All acceptance criteria verified: patch starts with 'diff --git', instruction.md >200 bytes (1965), grep -cE returns 0, Dockerfile has FROM
+- **Learnings for future iterations:**
+  - Tutanota is TypeScript (not Python/Go) — the test.sh uses `npx jest --timeout=60000` not pytest or go test
+  - The tutanota base image follows same /app pattern as qutebrowser/ansible — reuse Dockerfile structure with /workspace symlink
+  - Large patches (22KB, 9 files) can still be symptom-only: focus on the user-observable failure (blank mail body, missing reply-tos) not the API plumbing
+  - The grep AC check for `.ts` extension means instruction must use "(TypeScript)" suffix instead of `.ts` extension for the regression test path
