Consumer/Workspace Gemini Notebook, Workspace admin controls, Gemini Notebook Enterprise, source ingestion, chat/notes, Studio artifacts and downloaded copies are separate surfaces. Public specifications, independent evaluations and recovered first-party records are bounded evidence; none is promoted to all-path authorization, physical purge or universal accuracy. ## Mapping 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. 2. 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. 3. 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. 4. 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. 5. 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. 6. 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. 7. 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. 8. 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. 9. 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. 10. 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. ## Safe live test profile — not executed - Create a non-sensitive Drive document with revision ID and digest; import it and record the notebook representation and known omissions. - Change one authorized fact and observe auto-sync, open-triggered sync and manual sync timestamps separately. - Exercise owner, Drive viewer and notebook viewer roles; revoke source access and delete the source, then read back source, chat, notes, Studio artifacts, audio link and downloaded copy independently. - Use contradictory current/obsolete records and vary position, literal overlap, semantic association, hop count and aggregation. Keep NoLiMa, BABILong and LongBench v2 as test-intent taxonomies, not transferred scores. - Generate audio with fixed source subset, format, language, length and prompt; grade every claim as supported, omitted, distorted or unsupported against the source. - Test artifact deletion and account/notebook deletion as separate operations. Record only visible residuals; do not claim physical purge without retention/backup evidence. No live Google account, Workspace tenant, Enterprise instance, source ACL or audio generation was operated in this compilation run. ## Question disposition - Q-NLM-SCOPE-001: current public capture/sync/access behavior is bounded; all-path live and organization behavior remains UNKNOWN. - Q-NLM-SCOPE-002: visible lifecycle is separated; physical purge, internal retention and exported-copy control remain UNKNOWN. - Q-NLM-SCOPE-003: official warning, independent negative evidence and independent positive counterevidence are bounded; safe live fidelity/benchmark slices remain unexecuted. - Q-NLM-SCOPE-004: first-party operation records are recovered with partial provenance; individual artifact hashes/prompts/grades remain missing. ## Provenance - EXT-NLM-001..007: Google product/admin/Enterprise documentation, read 2026-09-13. - EXT-NLM-008: Flynn and Rader (2025), DOI 10.1029/2025CN000282. - EXT-NLM-009: comparative SLR evaluation (2026-09-03), DOI 10.3390/engproc2026154029. - EXT-NLM-010: first-party Drive records 1eHX_swOgNmxj2_ZZB-P4NffdoWLD30_s, 13KgN9o3caH3Sf7RU-BKcHFgppG5DdCwCsHOGCTn1aos, and combined corpus metadata 1zLdsb20_3agX-3ZODC61EmEh88OS9CyF. ## Exit condition NotebookLM CORE-02 supplement is bounded-complete for public, independent and recovered first-party evidence. Core claims are unchanged, so Gemini/GPT/Claude/Grok retrospective audits are not required. All-path ACL propagation, generated-artifact revocation, physical purge, exact historical artifact grading and Organization values remain routed residuals.
