+# ActivityDefinition: Legacy-Meter 8h Capture
+
+## Purpose
+
+`STATE-WP-0073` retirement-gate monitoring for `STATE-WP-0070` phase-2 legacy
+retirement. Runs every eight hours (UTC) and posts a compact
+`legacy_meter_8h_capture` progress event with window usage and retirement
+candidates.
+
+Complements the Monday weekly review (`weekly-legacy-meter-review`) which uses a
+7-day window. Seven consecutive zero-usage 8h windows unlock per-key 410
+retirements.
+
+## Trigger
+
+`0 */8 * * *` UTC — 00:00, 08:00, and 16:00 daily. `misfire_policy: skip`.
+
+## State Hub invocation
+
+The `legacy_meter_weekly_review` resolver issues:
+
+- `GET /legacy-meter/weekly-review?hours=8`
+
+On success, activity-core posts progress with `event_type: legacy_meter_8h_capture`
+and probe detail in `detail.probe`.
+
+Manual evidence files (for git-backed audit) remain on the workstation:
+
+```bash
+python ~/state-hub/scripts/capture_legacy_meter_evidence.py
+```
+
+## Output contract
+
+- One State Hub progress event per run (`legacy_meter_8h_capture`)
+- No LLM call; no workplan file edits
+- ActivityRun `context_snapshot` retains review summary for audit
