- Add SustainabilityMetrics type with KPIs: invocations, storage writes, events emitted, rewards distributed, content minted, active users, and efficiency score - Add SUSTAINABILITY_METRICS storage key - Add SustainabilityMetricsUpdatedEvent - Add SustainabilityManager with record, query, and health score logic - Expose 4 public contract entry points in lib.rs - Include unit tests for core metric tracking and health scoring

@Mrchinedum Great news! 🎉 Based on an automated assessment of this PR, the linked Wave issue(s) no longer count against your application limits. You can now already apply to more issues while waiting for a review of this PR. Keep up the great work! 🚀 |
- Add 8 sustainability Prometheus gauges to MetricsService
(invocations, storage writes, events emitted, rewards distributed,
content minted, active users, efficiency score, health score)
- Add updateSustainabilityMetrics() to push gauges on each query
- Add getSustainabilitySnapshot() to DashboardService: computes
real-time KPIs (efficiency, health, dispute rate, reward claim rate)
and pushes them to Prometheus
- Add GET /analytics/sustainability endpoint in ReportingController
- Add teachlink-sustainability alert group to prometheus/alerts.yml
with 5 rules: low efficiency, critical efficiency, low health score,
high error rate, no new transactions
- Create teachlink-monitoring-dashboard.json (691 lines, 20 panels):
- Row 1: Real-Time Platform Health (6 stat panels)
- Row 2: Historical Trends (4 time-series panels)
- Row 3: Alert Management (firing alerts, active count, critical count)
- Row 4: Platform Insights (cache ratio, latency percentiles,
dependency health, indexer progress, HTTP status breakdown)

fixed #390
feat: add comprehensive contract sustainability metrics
Sustainability metrics were not tracked anywhere in the contract.
This change introduces a dedicated module to define KPIs, record
resource usage, monitor efficiency, and report platform health.
What changed
contracts/teachlink/src/sustainability.rs (new)
snapshot stored in contract instance storage
optionally total_storage_writes on every tracked call
record_active_user — granular hooks for each KPI dimension
efficiency_score in basis points (0-10 000)
50 % efficiency score
25 % content creation (capped at 1 000 tokens = 100 %)
25 % user adoption (capped at 1 000 users = 100 %)
health_score_zero_ops
contracts/teachlink/src/types.rs
total_invocations, total_storage_writes, total_events_emitted,
total_rewards_distributed, total_content_minted,
total_active_users, efficiency_score, last_updated
contracts/teachlink/src/storage.rs
contracts/teachlink/src/events.rs
and efficiency updates (fields: total_invocations,
total_storage_writes, total_events_emitted, efficiency_score,
updated_at)
contracts/teachlink/src/lib.rs
get_sustainability_metrics → report metrics
get_sustainability_health_score → report health score
update_sustainability_efficiency → monitor efficiency
record_sustainability_invocation → track resource usage
Acceptance criteria met
✓ Sustainability KPIs defined (efficiency, resource usage, adoption,
content creation, rewards flow)
✓ Resource usage tracked (invocations, storage writes, events emitted)
✓ Efficiency monitored (basis-point score, updated via public entry point)
✓ Metrics reported (snapshot query + composite health score)
