Three fixups the Phase 1-3 work missed (would bite the first time an admin
flipped on a real event):
* IsDisplayTips + TipsId added to ColosseumSeasonConfig. Drives
Wizard/ColosseumEntryInfoTask.cs:129 (NeedsFirstTips = is_display_tips == 1).
The wire DTO already had the properties; the season config didn't carry
them, so admins had no way to gate the first-time tutorial tip popup.
* colosseum_id is now emitted from SeasonId. Wire field was always-absent
before (DTO had the property but builder never set it); client fell back
to 0 and couldn't disambiguate cups.
* ColosseumLobbyInfoBuilder.Build now takes ColosseumRoundsConfig + nowUtc
and derives the wire is_round_period / now_round / next_round / start_time
/ end_time from the rounds schedule against the current clock. Previous
hardcode (is_round_period: true, now_round: 1, event-window dates) would
have shown "Round 1 ends 2026-07-31" instead of the actual round's end.
Per the client parser at ColosseumEntryInfoTask.cs:111-126:
- inside a round → emit that round's window + is_round_period=true
- between rounds → emit next round's start as start_time + next_round
- pre-event → next_round=1, start_time=event start
- post-event → anchor to last round so the client doesn't NRE
- no rounds configured → fall back to event-level window
Why these were missed: I implemented ColosseumSeasonConfig from the plan's
explicit field list rather than cross-checking against the captured
colosseum.json wire shape; I added ColosseumId to the wire DTO without
wiring the builder side; and no test exercised a mid-event scenario with
realistic dates — Phase 2's E2E hand-edits run.RoundId via
PromoteRunToRoundAsync instead of letting the controller derive it.
* 10 new builder unit tests cover off-season / mid-round / between-rounds /
pre-event / post-event / empty-rounds-fallback + the new field surfacing.
Full suite: 1355/1355 (was 1345 + 10).
