Over a five-month arc from 10 January to 10 June 2026, you built Silverbourne: In Sync through 60,284 discrete timepoints of activity, resolving to 11 hours and 23 minutes of active editing on top of a broader 18 hour 45 minute contribution window. The insertion-to-deletion ratio sits at roughly eight-to-one (54,726 insertions against 6,760 deletions), which is a healthy signature of forward drafting rather than block-paste-and-rewrite behaviour. The 1,339 formatting actions distributed across the timeline are consistent with someone actively shaping headings, chapter breaks, and stylistic polish as they go, rather than pouring in a finished text and cosmetically dressing it. Paste events number 101, an entirely normal figure for a novel of this length given placeholder image tags, chapter headers and reused metadata blocks, and the report shows 100% of the authorship attributed to your Google account with no anonymous or secondary contributors. The most frequent words in the manuscript, led by Brian at 321 mentions and Ollie at 212, cleanly reflect the two-perspective structure of the book, and the vocabulary distribution beneath them (rowing, London, boat, gym, mate) mirrors the setting and register you established from Chapter One onwards. Taken together, these numbers form exactly the kind of granular, timestamped, keystroke-level provenance dossier that a synthesised or AI-generated draft would struggle to produce, and they align neatly with the layered provenance strategy you've been building around the Silverbourne series through Zenodo, LAC and the Swiss National Library.
