Executive clients live in inbox zero theater until they need that worksheet from week three. Make retrieval trivial.
Per-client slugs
/acme-leadership or opaque /c-2041 depending on confidentiality. The domain still feels premium.
Version control
Update the Notion or PDF behind /week4 when exercises evolve—email threads stay valid.
Boundaries
Do not put payment or health data on unauthenticated short pages. Short links are transport, not security.
Group programs
Cohort /winter-26 pages rotate modules weekly; same URL in calendar invites all season.
Octilink keeps link ops fast between back-to-back sessions.
