Phase C + F of the host-driven event scheduling work, building on PR #43's CalendarEventSyncer + repos. No UI yet — that's the next PR. Service (internal/services/hosted_event.go): - HostedEventService with Create / Update / Cancel / Get / List / Archive / Unarchive / RetryCalendarEvent / DetectBusyConflicts. - Calendar resolution: explicit input → template → host default → first writable (the syncer's resolveWritableCalendarID handles the last fallback). - Conferencing-link write happens twice: once after CreateMeetingForHostedEvent (Zoom path) and again after the syncer surfaces a Google Meet link from the calendar create response — matches the booking flow's coupling. - ErrConferencingReauthRequired on create logs and continues; the event still persists. On Update it surfaces (parity with booking.go:425). - Update flow computes field + attendee diffs (lowercased email keys), resets reminder_sent when Start changes, and only upserts contacts for newly added attendees so retained attendees don't get meeting_count re-incremented on a benign edit. - Email diff: removed → SendHostedEventCancelledForAttendee, added → SendHostedEventInvited, retained (when material field changed) → SendHostedEventUpdated. - DetectBusyConflicts merges three sources (provider busy, confirmed bookings, scheduled hosted events) with excludeEventID for self-edit. - Service depends on a narrow hostedEventEmailSender interface so tests can inject a spy without dialling SMTP. Conferencing (internal/services/conferencing.go): - Extracted createZoomMeetingRaw(ctx, hostID, topic, start, durationMin) so both bookings and hosted events share the Zoom API call. - New CreateMeetingForHostedEvent(ctx, hostID, title, start, duration, locationType, customLocation). CreateMeeting(details) keeps its existing signature and now delegates to createZoomMeetingRaw internally. Contacts (internal/services/contact.go): - New UpsertFromHostedEventAttendee. Callers invoke this only for newly added attendees so meeting_count and last_met don't drift on edits. Email (internal/services/email.go): - SendHostedEventInvited / Updated / Cancelled / CancelledForAttendee / Reminder, plus generateICSForHostedEvent. Inline-Go-string pattern matching SendBookingConfirmed at email.go:184. Cancellation paths emit METHOD:CANCEL ICS so calendar clients remove the event. Reminder (internal/services/reminder.go): - checkAndSendReminders now splits into processBookingReminders + processHostedEventReminders so a partial failure in one source doesn't abort the other. Tests: - internal/services/hosted_event_test.go: 13 cases covering persistence, calendar resolution priority, ErrConferencingReauthRequired handling, Google Meet link surfacing through the syncer, invited-email fan-out, contact upsert, attendee-diff email routing (added/removed/retained), reminder_sent reset on Start change, no-op-update sends no email, Update.PatchesAllTrackedCalendarEvents, retained-attendee contact not re-upserted, Cancel deletes tracking rows + cancellation emails, DetectBusyConflicts excludes self when editing. - internal/services/reminder_test.go: end-to-end pass through processHostedEventReminders flips reminder_sent and prevents re-fire. go vet clean. All previously-passing tests still pass. Build clean. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

… + E) (#47) * refactor(calendar): extract calendar fan-out into CalendarEventSyncer Phase A of the host-driven event scheduling work (see plan in /root/.claude/plans/here-is-a-draft-cryptic-crane.md). Pure refactor; no behavioural change for bookings. - Introduce CalendarEventInput as a provider-agnostic event shape and refactor CreateEventForHost / UpdateEvent / the private Google + CalDAV helpers to take it. CreateEvent(*BookingWithDetails) stays as a thin booking-side adapter; new BuildCalendarEventInputForBooking composes description + reschedule URL + attendees from the booking shape. - Add the calendarEventWriter interface so the syncer can be tested without hitting the network. - New CalendarEventSyncer.Create / Update / Delete fans out across all host targets and persists tracking rows in booking_calendar_events. The Update path explicitly persists any replacement event_id returned by the calendar layer (CalDAV delete+create or fall-through to create when the prior ID was empty), so subsequent updates and deletes target the correct provider event. - BookingService loses its three duplicate fan-out helpers (createPooledHostCalendarEvents, updateAllCalendarEvents, deleteAllCalendarEvents) and now goes through the syncer. The legacy pre-pooled-host fallback (booking.CalendarEventID with template.CalendarID) is preserved for old rows. - Regression tests cover one-host create, pooled-host fan-out, per-host failure isolation, the CalDAV replacement-id and prior-id-empty persistence invariants, delete fan-out, and Google Meet conference link surfacing. https://claude.ai/code/session_01YWosUoHN5qrc7bTrTv1hzM * feat(hosted-events): schema, models, and repositories Phase B of the host-driven event scheduling work. DB-only — no service or handler wiring yet. - Migration 014 adds hosted_events, hosted_event_attendees, and hosted_event_calendar_events for both postgres (root migrations/) and sqlite (migrations/sqlite/). status enum is intentionally narrow for v1 (scheduled | cancelled). - Models HostedEvent, HostedEventAttendee, HostedEventCalendarEvent, and HostedEventStatus mirror the booking shapes' SQLiteTime / db tag / json tag style. - HostedEventRepository: Create, GetByID, Update, ListByHost, GetByHostIDAndTimeRange (with excludeEventID for self-collision filtering on edits), GetUpcomingForReminders, MarkReminderSent. - HostedEventAttendeeRepository.ReplaceForEvent: atomic delete-and-insert in a transaction. Source of truth for the attendee diff is whatever this method commits. - HostedEventCalendarEventRepository: Create / GetByHostedEventID / Update / DeleteByHostedEventID — same shape as BookingCalendarEventRepository. - Register the hostedEventTrackingStore on CalendarEventSyncer so the ItemKindHostedEvent dispatch is now wired (was a stub in Phase A). - Round-trip tests for the new repos under sqlite. Note on placeholders: q(driver, sql) does plain regex substitution of $N to ?, so under sqlite the bind order follows the order placeholders appear in the query — not their numeric value. Out-of-order $1/$3/$2 silently mis-binds. New time-range methods order placeholders strictly ascending and document this constraint inline. https://claude.ai/code/session_01YWosUoHN5qrc7bTrTv1hzM * feat(hosted-events): HostedEventService + email + reminder integration Phase C + F of the host-driven event scheduling work, building on PR #43's CalendarEventSyncer + repos.

All previously-passing tests still pass. Build clean. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(hosted-events): dashboard handler, routes, and UI templates (Phase D + E) Phase D + E of host-driven event scheduling. Builds on the HostedEventService introduced in #44 and exposes it through 12 dashboard routes plus 6 HTML templates. Sidebar gets a "Schedule Event" item between Templates and Bookings. ## Routes (cmd/server/main.go) - GET /dashboard/events — list (?archived=true to include) - GET /dashboard/events/new — create form (?template=ID prefills) - POST /dashboard/events — create - GET /dashboard/events/check-conflicts — HTMX partial; busy-time merge - GET /dashboard/events/attendee-search — HTMX partial; contact autocomplete - GET /dashboard/events/{id}/details — modal partial - GET /dashboard/events/{id}/edit — full edit form - POST /dashboard/events/{id}/edit — update - POST /dashboard/events/{id}/cancel — cancel - POST /dashboard/events/{id}/archive — archive - POST /dashboard/events/{id}/unarchive — unarchive - POST /dashboard/events/{id}/retry-calendar — retry calendar event creation The HTMX partial routes use the /events/check-conflicts and /events/attendee-search paths so they don't shadow {id}. ## Handler (internal/handlers/dashboard_events.go) DashboardEventsHandler wired on the Handlers struct alongside Dashboard. Form parsing uses parallel-indexed repeated form fields (attendee_email/_name/_contact_id), matching the existing pattern used by the templates handler. parseDateTimeInTZ combines the form's date + time + timezone fields into a UTC time.Time before handing to the service. Update flow uses pointer fields on UpdateHostedEventInput so the form can express "unchanged" vs "set to empty". ## Templates (Phase E) All six new templates reuse the existing primitives — `.section`, `.section-header`, `.form-input`, `.form-select`, `.form-textarea`, `.form-label`, `.form-hint`, `.btn .btn-primary/.btn-secondary/.btn-outline`, `.btn-sm`, `.badge`, `.table-container/.table`, `.duration-chips`, `.radio-cards`, `.modal-overlay/.modal-content/.modal-header/.modal-body`, `.empty-state`, `.alert/.alert-warning/.alert-error`. No new CSS files; the attendee chip styling is a small inline block confined to the form template. - templates/pages/dashboard_events.html — list + filter view - templates/pages/dashboard_event_form.html — create + edit form - templates/partials/events_table_partial.html — table body - templates/partials/event_attendee_picker_results.html — autocomplete results - templates/partials/event_conflict_warning.html — soft conflict banner - templates/partials/dashboard_event_detail_partial.html — modal detail The form has 7 sections (Template prefill (new only) → Basics → When → Location → Calendar → Attendees) with HTMX-driven conflict warnings and contact autocomplete. Modal pattern matches the booking flow's recent fetch-based approach (#41 pattern). ## Tests internal/handlers/dashboard_events_test.go — 9 cases: - TestEventAttendeePickerResults_RendersContacts - TestEventAttendeePickerResults_EmptyShowsFreeFormHint - TestEventAttendeePickerResults_EmptyAndNoQuery_RendersNothing - TestEventConflictWarning_RendersConflicts (asserts pluralisation + soft-warning copy) - TestEventConflictWarning_NoConflicts_RendersEmpty - TestEventsTablePartial_RendersScheduledAndCancelled (status-routed badges + actions) - TestEventForm_NewMode_RendersTitleAndAttendeePicker - TestEventForm_EditMode_PrefillsAndCarriesExcludeEventID (zoom + 45-min + exclude_event_id) - TestEventForm_FormErrorRendersHumanCopy (at_least_one_attendee → human copy) Pattern matches internal/handlers/template_test.go: load real template files, render to bytes.Buffer, assert strings. Tests render the {{define "content"}} blocks directly to avoid the layout-loading dependency. `make test`, `go vet ./...`, `go build ./cmd/server` all clean.

Summary
Phase C + F of the host-driven event scheduling work. Builds on the syncer + schema/repos already in #43 (this PR is targeted at #43's branch so the diff shows only the new work; once #43 merges to main, this PR will auto-rebase).
This PR is service + tests only — no handlers, no UI, no migrations. The next PR adds Phase D + E (routes/handlers + the dashboard UI via the `frontend-design` skill).
What's new
`HostedEventService` (`internal/services/hosted_event.go`)
Public surface: `Create`, `Update`, `Cancel`, `Get`, `List`, `Archive`, `Unarchive`, `RetryCalendarEvent`, `DetectBusyConflicts`.
Behavioural notes worth highlighting in review:
Conferencing (`internal/services/conferencing.go`)
Extracted `createZoomMeetingRaw(ctx, hostID, topic, start, durationMin)` so both bookings and hosted events share the Zoom API call. New `CreateMeetingForHostedEvent(...)`. Existing `CreateMeeting(details)` keeps its public signature and now delegates internally.
Contacts (`internal/services/contact.go`)
New `UpsertFromHostedEventAttendee(ctx, tenantID, email, name, eventStart)`.
Email (`internal/services/email.go`)
Five new send methods following the inline-Go-string pattern of `SendBookingConfirmed` (`email.go:184`):
Plus `generateICSForHostedEvent(event, host, attendee, method, status)`.
Reminder (`internal/services/reminder.go`)
`checkAndSendReminders` now splits into `processBookingReminders` + `processHostedEventReminders` so a failure in one source can't abort the other.
Tests
`internal/services/hosted_event_test.go` — 13 cases:
`internal/services/reminder_test.go` — `processHostedEventReminders` flips `reminder_sent` and prevents re-fire.
