Auto-detect CSV format from the header:
• meetings-inactive: EMAIL / IS_HOST / DAYS_SINCE_LAST_ACTIVE
(Analyzer → Meetings → Inactive Users)
• users-export: "User ID/Email (Required)" /
"Days since Last Service Accessed"
(Users → Manage users → Export)
The users-export report has no host flag, but we don't need one —
the authoritative host-holder set comes from the live assignee
roster fetched from the Webex API. Format-B rows with blank
"Days since Last Service Accessed" (never-signed-in accounts,
often generic mailroom/store logins) are intentionally skipped so
they aren't silently reclaimed.
Also stopped upper-casing the header so we can preserve the
punctuation-rich column names Users Export uses verbatim.
Reads a Control Hub "Meetings Inactive Users" CSV, filters to
IS_HOST=Y AND DAYS_SINCE_LAST_ACTIVE > --min-days (default 120),
cross-references against the current holders of --host-license-id
(so no per-user /people lookup), then PATCHes /v1/licenses/users to
atomically remove the host license and either (a) add a specific
free-tier license (--free-license-id) or (b) add attendee-only
siteUrl on --site (--free-attendee).
Dry-run by default; enumerates every license on the site so the
operator can pick the free tier. Bounded concurrency with 429/503
retry, optional --offset/--limit for staged rollouts, per-user
outcome CSV via --report, and full audit trail via the existing
webex:reclaim:audit log scope.
Whitelisted in .gitignore so it stays version-controlled alongside
the other tracked operational scripts.
