about

nx_vizsla_calendar.nx -- NISHI VIZSLA R-CAL.0: the calendar substrate (events + FREE/BUSY). Operator 2026-06-22: "...running our personal relationship management and calendar and to dos..." The census (nx_vizsla_census) measured the ENTIRE calendar area ABSENT; this is the keystone rung it names -- everything time-based (recurrence R-CAL.1, conflicts R-CAL.2, time-blocking R-CAL.3) composes on it. Events are CID records on the SAME tamper-evident seg_store data plane as money (V1) + relationships (V4) + maintenance (V6): additive, idempotent-by-construction (law 10), as-of time-travel. FREE/BUSY is computed integer-only (NO-FLOAT) -- busy = merged union of [start,start+dur); free = the complement within the 1440-minute day. Determinism: stdout has no clocks (today/date are argv). Commands (argv[1]): load <eventsfile> <prefix> [segid] EVENT <id> <date YYYY-MM-DD> <start_min> <dur_min> <title> -> "cal:" CID records on seg_store. day <prefix> <date> the day's events sorted by start + merged BUSY intervals + the FREE complement within [00:00,24:00) + a verdict line. Loud-fail law: missing file, bad date, non-digit/out-of-range start|dur, event crossing midnight = exit 1. EXCEED (grounded knowledge/fetched/pa_c2_icalendar.raw VEVENT/VFREEBUSY): free/busy on a sovereign, auditable, time-travelable data plane -- Google Calendar's free/busy is a cloud query with no portable history. spec: knowledge/research/2026-06-22-vizsla-sclass-roadmap.md license_tier: ORIGINAL
