 ### Added
 
+- Drive research acceptance selects exact version-specific export and memory-search contracts,
+  and records aggregate read-only Google import/recovery results without publishing source data.
+
 - The installed Drive research check now verifies person links, stale-note revision refusal,
   scoped source-backed memories and local source retirement through the released CLI. It
   checks persisted memory staleness and owner-note preservation with synthetic data only.

+reusable isolated acceptance runner. The owner later explicitly authorized read-only checks with
+an existing profile; aggregate results are recorded below, alongside synthetic package validation.
+
+## Read-only Google acceptance
+
+The owner asked to validate an existing selected folder using its already connected profile.
+On 2026-10-15, Linux/Node 24.19.0 and installed Drive 0.7.0 (Core 0.278.0/Base 0.28.2)
+read Google while keeping all content, database, checkpoints and model-cache paths in a new
+private workspace. Original authentication was reused; the owner's database was not opened.
+Google files, sharing and permissions were never modified.
+
+| Check | Observed result |
+| --- | --- |
+| Complete selected catalog | 443 entries: 65 folders and 378 files |
+| Full import | 197 text-indexed files; 181 metadata-only; zero pending jobs |
+| Metadata-only reasons | 179 unsupported types; one scanned PDF without a text layer; one unreadable XLSX |
+| Cached hierarchy and metadata | Complete folder ancestry/tree and retained provider metadata |
+| Initial offline batch | 20 files; 56 assertions passed with network/browser/keyring denied |
+| Reader coverage | Exact word search and byte-exact Markdown export passed for one file each in eight categories |
+| Live Google Docs comparison | Five single-tab Docs; 937 fragments and two tables matched; provider versions stayed stable |
+| Interruption and resume | Own CLI exited 130 after SIGINT; resumed and drained pending jobs |
+| Local document context | Temporary tag, note and proposed source-backed memory survived interruption and repeated sync |
+| Repeat import | Zero new text saves; zero pending jobs; source references preserved |
+
+The eight categories were Google Docs, Google Sheets, PDF, DOCX, XLSX, CSV, Markdown and TXT.
+Exported files had mode 0600. The TXT test initially normalized CRLF while comparing Python
+strings; comparing UTF-8 bytes established exact preservation. This was a harness issue.
+
+Private report and scripts: `cli-private/reports/drive/2026-10-15-live-read/`. Queries, source IDs,
+per-file outcomes and local workspace paths stay there. These scripts describe historical staged
+checks on that authorized workspace; they are not an invitation to use arbitrary owner accounts.
+The reusable synthetic runner below remains independent of this live run.
+
+This establishes reading and offline retrieval for this selected tree. It does not certify fresh
+OAuth consent, Google verification, all fields on every account, remote writes, AI extraction,
+embeddings or OCR. No footnotes or multiple/nested tabs occurred in the five-Doc live sample.
+
+## Fresh-install compatibility
+
+Drive 0.8.0 changes export to `--output` and memory search to a list envelope. The version-aware
+checker accepts exact reviewed pins and selects the corresponding contract, retaining 0.7.0's
+`--out` and rich memory-search result. Ten synthetic guard tests pass; 0.7.0's 8 initial, 8 repeat
+and 7 knowledge lifecycle groups still pass after these checker changes.
+
+A fresh npm 0.8.0 install passed the same lifecycle groups but failed broader discovery checks:
+Core 0.281.0 asks for Base 0.28.x, while Drive pins Base 0.31.0. npm installs two instances and
+generated API commands lose their operation identity/effects. Do not interpret the lifecycle
+pass as full standards acceptance. The producer correction is
+[Core PR 1257](https://github.com/WireCatLabs/cli-core/pull/1257).
+
+The aligned candidate (Core 0.283.0/Base 0.31.1) passes 41 CLI invocations and three MCP
+validation/audit calls. Its installed Node and Bun smoke checks require generated read/write
+operation identities and correct remote effects. Drive also preserves its existing one-time
+camelCase config migration after the producer stopped converting old settings. Candidate
+results must be distinguished from the eventual published patch's installation results.
