Effective permissions are the intersection of Reddit mod-perms and ContextMod role grants. All mutations require head-mod approval and emit a CONFIG entry to the audit log.

Owner: head-mod-jane · Sign-off due 2026-05-25
Why this passes procurement
  • Functional parity 96.4% verified by automated rule-pack diff
  • SLA gauge with p50/p95 + uptime, retained 365d
  • Hash-chained audit log, signed CSV/JSON export
  • RBAC enforced at rule-pack granularity, least-privilege
  • Devvit-native — no external host, satisfies platform constraint
Open risk register
  • 8 deferred legacy rules (low-frequency, <0.4% of actions)
  • p95 latency band 887 ms — within SLA, monitor weekly
  • Apprentice role currently read-only; revisit after 30d
