…tle (2.16c)

createEventSeries takes fromEventKey: an event already set up becomes the first date under its own key and every other date is a copy of it; name and chartKey are then left out. Every date of a series carries the series' plain name. Matches seatmap slice 2.16c.

Adds releaseSeasonLapsedOffers (POST /v1/seasons/{key}/renewal-offers/release-lapsed, no body, header replay, 202 with the job). retrieveSeasonHostedRenewals pages with cursor and limit (1-500) and answers nextCursor, and listSeasonRenewalOffers pages the same way (1-100). createSeasonRenewalOffers answers 201 {offers} for 100 contracts or fewer and 202 {job, batchId} above that. The bring-across (createSeasonHolderImportFromSeason) answers 202 with a holder_import job above 100 holders. Renewal emails take up to 20,000 offer ids; above that, 422 too_many_offer_ids.

…e_abandoned (p2b)

The public API changes in p2b (b88ed794e..ee7df2921): season_date_cancel_void_job_id names the date_cancel_void job a date cancel starts (season.ticket.voided reason date_cancelled); season_holder_import_rows_per_call sizes a create_season_holder_import call by its dates, now 2 to 50 (a call over it raises SeatLayerValidationError invalid_rows with maxRows); update_season documents singleTicketDates.jobRefused and its exact-retry guard; create_event_series documents 409 create_abandoned. Both helpers are module functions exported from seatlayer.

…b audit)

updateEventSeries sends only the prices that change: each date keeps its
own price for every category or tier left out. A season's null transfer
or return cut-off means the club default from Settings > Ticket site, or
until the date starts when the club has none. Holder transfers and
returns through the secret key are not stopped by the club's customer
switches; cut-offs still apply.

…part C)

A date its season cancelled never opens again: moving its sales to
testable or live, or reopening it, answers 409 season_date_cancelled,
and an event series "sales on" leaves it closed as a failed item of the
job (season_date_cancelled; not in failedDates). A cancelled date can't
be moved, postponed, replaced or marked as taken place: 409
performance_cancelled.
