      "text": "1. MAPPING_ID: PM-C02-NLM-001; CORE REQUIREMENT: source identity and freshness; NOTEBOOKLM SURFACE: Drive sources may auto-sync after source change and can be manually synchronized; web, YouTube and uploaded files have different capture semantics; EVIDENCE / BOUNDARY: EXT-NLM-001. A copied/imported representation is not the source-of-truth object.\n\n2. MAPPING_ID: PM-C02-NLM-002; CORE REQUIREMENT: permission-aware retrieval; NOTEBOOKLM SURFACE: Loss of view access or deletion makes a Drive source inaccessible to the notebook, while Workspace admin separately controls external sharing; EVIDENCE / BOUNDARY: EXT-NLM-001/005. This is a published product contract, not an all-path live proof across cache, chat, Studio artifacts, exports or Enterprise.\n\n3. MAPPING_ID: PM-C02-NLM-003; CORE REQUIREMENT: fidelity of captured source; NOTEBOOKLM SURFACE: Footnotes/comments are not imported; multiple spreadsheet tabs can be combined; the notebook representation may differ from the original; EVIDENCE / BOUNDARY: EXT-NLM-001. Source presence is not byte fidelity or complete support coverage.\n\n4. MAPPING_ID: PM-C02-NLM-004; CORE REQUIREMENT: citation contract; NOTEBOOKLM SURFACE: Chat can use all or selected sources; short sources may lack individual citations; saved notes can preserve citations; EVIDENCE / BOUNDARY: EXT-NLM-004. Citation presence, support completeness, source freshness and authorization remain separate assertions.\n\n5. MAPPING_ID: PM-C02-NLM-005; CORE REQUIREMENT: memory/lifecycle; NOTEBOOKLM SURFACE: source, notebook, chat history, note, generated audio, share link and downloaded copy have separate delete/retention paths; feedback retention is account/context dependent; EVIDENCE / BOUNDARY: EXT-NLM-002..004. Visible deletion is not physical purge; cache, backup and internal residuals remain UNKNOWN.\n\n6. MAPPING_ID: PM-C02-NLM-006; CORE REQUIREMENT: artifact authorization; NOTEBOOKLM SURFACE: Audio links depend on notebook sharing/full access; deleting the audio invalidates the link, while a download is a separate copy; EVIDENCE / BOUNDARY: EXT-NLM-003. Source revocation, artifact revocation and exported-copy governance must be tested separately.\n\n7. MAPPING_ID: PM-C02-NLM-007; CORE REQUIREMENT: generated-audio fidelity; NOTEBOOKLM SURFACE: Google warns that generated audio may contain inaccuracies or glitches; an independent three-paper planetary-science test found at least some inaccuracy or hallucination in each summary; EVIDENCE / BOUNDARY: EXT-NLM-003/008. Audio is an assistive synthesis, not a replacement for source readback.\n\n8. MAPPING_ID: PM-C02-NLM-008; CORE REQUIREMENT: bounded counterevidence; NOTEBOOKLM SURFACE: A 40-paper systematic-review study reported 11/11 NotebookLM citations in its evaluated slice matched the corpus and no out-of-corpus citation in those conditions; EVIDENCE / BOUNDARY: EXT-NLM-009. This useful contrary result is slice-specific and does not establish universal citation or reasoning performance.\n\n9. MAPPING_ID: PM-C02-NLM-009; CORE REQUIREMENT: first-party operation provenance; NOTEBOOKLM SURFACE: A recovered 2026-07-31 report records 14 Audio Overviews, transcription use and combined-corpus operation; a related strategy record notes subject/causal abstraction loss; EVIDENCE / BOUNDARY: EXT-NLM-010. Individual input/output hashes, exact prompts and per-artifact grading are missing, so no success rate or general product claim is inferred.\n\n10. MAPPING_ID: PM-C02-NLM-010; CORE REQUIREMENT: Organization Overlay; NOTEBOOKLM SURFACE: adopted edition, domain/OU/group sharing setting, allowlist, retention, DLP/Model Armor, owners and incident controls are organization values; EVIDENCE / BOUNDARY: EXT-NLM-005..007. Public availability is not the user's effective configuration."

Keep NoLiMa, BABILong and LongBench v2 as test-intent taxonomies, not transferred scores.\n\n- Generate audio with fixed source subset, format, language, length and prompt; grade every claim as supported, omitted, distorted or unsupported against the source.\n\n- Test artifact deletion and account/notebook deletion as separate operations. Record only visible residuals; do not claim physical purge without retention/backup evidence.\n\nNo live Google account, Workspace tenant, Enterprise instance, source ACL or audio generation was operated in this compilation run."
