One event per (session, page, channel) within an aligned window of readTrail.dedupWindowMinutes (default 5): buckets are floor(epoch / windowSeconds), and a unique (dedup_key, window_bucket) pair collapses concurrent duplicates race-free at insert time — the first access in a window is always recorded, a later duplicate lands on the unique violation and is skipped quietly (a skipped duplicate is not a gap; only real write failures still abort the read). Each row carries windowSeconds, so the evidence states it represents a window, never a request count. Reconnects within a window stay one event; a new session records again even for the same user; channels never collapse into each other; the page-less attachment key uses the documented `-` placeholder. Load evidence: 30 collab-token renewals inside one window produce exactly one event (test), bounding a live editing session at ~12 events/hour/page. Window semantics documented in ADR 0023, the VS-NfD security documentation (#228) and as a hardening-guide line for the new setting (care rule: same PR). Refs #223.
