PowerGRYD — Trend & Trajectory

Trend & Trajectory at /reports/powergryd/trends charts the last 12 months of PowerGRYD maturity snapshots so you can see whether each layer and overall pyramid integrity are improving.

Snapshot capture

Snapshots are written to powergryd_maturity_snapshots by the cron-powergryd-snapshot edge function:

Nightly — 08:00 UTC, idempotent per UTC day (no duplicate row if one already exists).
Manual — toolbar button (OrgAdmin Pro+Ent) with role/org check and a 60-minute throttle to prevent flood.

Last-snapshot strip on the page tags the row as nightly + System (cron) ormanual + actor based on the capture path.

Chart & window

Window — last 12 months, oldest → newest.
Lines — one per PowerGRYD layer (L1–L5) plus pyramid integrity, rendered with Recharts LineChart.
Legend — click any series to toggle its line on/off (per-line legend toggle).
Empty state — when fewer than 2 snapshots exist (hasInsufficientHistory), an explainer renders instead of an empty chart.

Timezone handling

Display dates honour the org timezone via useOrgTimezone. CSV export uses MM/DD/YYYY HH:MM with the org-local clock, matching all other RAIC report exports.

Export & audits

Export produces RhindonCyber_PowerGRYD-Trend-12mo_*.csv (CRLF, MM/DD/YYYY HH:MM, org-tz).

Audits: POWERGRYD_TREND_VIEWED (60-min throttled), POWERGRYD_TREND_EXPORTED, POWERGRYD_TREND_SNAPSHOT_CAPTURED (cron), POWERGRYD_TREND_SNAPSHOT_MANUAL. Tier/flag gating: Pro+Ent and feature_flags.powergryd.
