[EVENT_BRIEF_AND_PRIORITIES]: Sixty-guest civil wedding with a 3:00 PM city-hall ceremony, rooftop dinner at a second venue, private first look, immediate-family portraits, and a relaxed guest experience as the top priority.
[CURRENT_TIMELINE]: Hair and makeup 10:30 AM-1:00 PM; photographer coverage 1:00-7:00 PM; first look proposed for 1:30 PM; ceremony 3:00-3:25 PM; dinner venue opens to guests at 5:00 PM; toasts planned before sunset portraits.
[VENDOR_AND_VENUE_CONSTRAINTS]: City hall requires check-in at 2:30 PM and allows ten minutes for group photos afterward; rooftop vendor access begins at 3:30 PM; couple travel between venues is 25-40 minutes; caterer needs final seating by 5:20 PM.
[COVERAGE_AND_CONTINGENCY_NEEDS]: Protect first look, family portraits, ceremony exit, rooftop details before guests enter, golden-hour couple portraits at 6:15 PM, and a rain fallback using the dinner venue's covered terrace.

Civil Wedding Production Run of Show
1. Executive Control Note
Recommended scenario
Guest-Flow Protected is recommended because the stated top priority is a relaxed guest experience. It preserves the fixed city-hall ceremony, avoids sending guests to a closed rooftop venue, protects the caterer’s 5:20 PM seating deadline, and retains the 6:15 PM portrait priority.
Confidence
Medium—conditional.
The ceremony-to-rooftop sequence is workable using the supplied 25–40-minute travel range. The pre-ceremony sequence and dinner/toast sequence cannot yet be proven because essential durations and locations are missing.
Unresolved blockers
First-look-to-city-hall feasibility:
The proposed 1:30 PM first look and 2:30 PM check-in leave 60 minutes calculated for the first look, any pre-ceremony portraits, and travel from the first-look location. That travel time and location are unknown.
Immediate-family portrait scope:
City hall permits only ten minutes of group photography after the ceremony. A final grouping list is required to prove that the protected portraits fit.
Rooftop setup readiness:
Vendors receive access at 3:30 PM, but setup durations and the photo-ready handoff time are unknown.
Toast, meal, and portrait sequencing:
Toast duration, dinner-service timing, and the transition time needed to begin portraits at exactly 6:15 PM are unknown.
Guest transport and accessibility:
No guest transport, accessible route, elevator, drop-off, or mobility-assistance plan has been supplied.
Control ruling
The 3:00 PM ceremony must not move. The 2:30 PM check-in, 3:30 PM rooftop access, 5:00 PM guest doors, 5:20 PM final seating, 6:15 PM portraits, and 7:00 PM photography end remain controlling boundaries.

4. Conflict Register
Severity Collision and supplied evidence Dependency chain Smallest viable correction Decision owner Decision deadline Reversibility
1 — BLOCKER First look at 1:30 PM; check-in at 2:30 PM. Only 60 minutes calculated remain for first look, possible portraits, and unverified travel. HMU finish → dressing → first look → transfer → city-hall check-in Confirm the first-look location and route. If feasibility cannot be proven, relocate the first look to an approved private area at or immediately adjacent to city hall. Couple + planner + photographer Before final call sheet Relocation is reversible; venue or transport changes may carry cost
2 — HIGH Immediate-family portraits are protected, but city hall allows only ten minutes after the ceremony. Ceremony end → family gathered → groupings → city-hall release Approve a ten-minute essential grouping list and appoint one family wrangler. Move only nonessential combinations to a conditional rooftop fallback. Couple + photographer Before photo brief is issued Shot-list reduction is reversible before event day
2 — HIGH Guests departing at 3:25 PM would reach the rooftop at 3:50–4:05 PM calculated; departing at 3:35 PM gives 4:00–4:15 PM calculated arrival. Doors open at 5:00 PM. Ceremony release → guest travel → closed venue Do not operate an immediate guest convoy. Issue a 5:00 PM arrival instruction and a clear self-directed interval or approved holding plan. Planner + guest-flow lead Before invitations or transport message is finalized Communication change is highly reversible
2 — HIGH Rooftop vendor access starts at 3:30 PM; photographer arrives no earlier than 4:00–4:15 PM if completing city-hall photos. Setup duration is unknown. Access → setup → venue handoff → photographer arrival → doors Require a room-by-room photo-ready handoff and priority detail list. Scenario 2 may add a second coverage role at 3:30 PM. Venue manager + photography lead Before vendor call sheet Handoff standard is reversible; added staffing is expensive
2 — HIGH Toasts are planned before 6:15 PM portraits, but dinner start and toast duration are unknown. Final seating → service release → toasts → portrait transition → 6:15 start Caterer must approve the toast window. Calculate the toast cut-off as 6:15 PM minus confirmed transition time. Move overflow to after portraits. Catering captain + emcee + photographer Before banquet timeline approval Moving toasts is reversible; catering changes may not be
2 — HIGH Covered terrace is the fallback, but no weather threshold, reset duration, capacity, or dry route is supplied. Forecast/conditions → decision → setup allocation → guest doors Venue defines the threshold and terrace operating plan. The latest provisional event-day activation gate is 3:30 PM, subject to any earlier setup requirement. Venue manager + planner Before final call sheet; event-day confirmation no later than 3:30 PM Early activation is reversible; late reset may create labor cost
3 — MEDIUM HMU ends at 1:00 PM and first look is at 1:30 PM, leaving a 30-minute calculated readiness window. Dressing and transfer duration are unknown. HMU release → dressing → details → first look Treat 1:00 PM as a hard chair-release. Confirm dressing and movement requirements; drop non-priority preparation coverage before moving the ceremony sequence. HMU lead + planner + photographer Before HMU schedule lock Preparation coverage is reversible
3 — MEDIUM Sixty guests have only 20 minutes calculated between 5:00 PM doors and 5:20 PM final seating. Doors → greeting/check-in → finding seats → final seating Pre-assign seating, use visible table guidance, and place staff at entry and seating points. Exact staffing remains TBC. Venue manager + planner + caterer Before floor plan and staffing lock Signage and staffing are generally reversible
2 — HIGH No accessible transport, route, elevator, restroom, or rain-route information is supplied. City-hall exit → vehicle/loading → rooftop entry → seating Assign an accessibility lead and confirm an accessible route and vehicle plan for every guest who requires it. Planner + venue manager Before guest transport instructions May become expensive if vehicles or rentals are added late
3 — MEDIUM Photography ends at 7:00 PM; portraits begin at 6:15 PM, leaving a maximum 45-minute calculated window before coverage ends. Toast and portrait durations are unknown. Toasts → portrait start → portrait duration → coverage end Confirm portrait duration and final photographed moment. If toasts move after portraits, extend coverage or accept that they may be unphotographed. Couple + photography lead Before photography contract lock Coverage extension may carry cost
3 — MEDIUM Rooftop hard end, curfew, strike access, and vendor departure rules are missing. Reception activities → breakdown → strike → venue release Obtain written venue hard-end and strike requirements. Do not publish an event-end or strike time until confirmed.

Scenario 2 control conditions
This scenario is viable only if:
A second coverage role is contracted for rooftop access and setup documentation.
Photography or video coverage is extended beyond 7:00 PM by a duration sufficient to cover the post-portrait toasts.
Catering approves moving toasts after portraits.
The same first-look, family-shot-list, accessibility, weather, and guest-arrival gaps are resolved.
7. Scenario Comparison
Factor Guest-Flow Protected Coverage-and-Production Protected
Guest impact Lowest if guests receive a clear 5:00 PM arrival instruction; toasts remain before portraits if catering approves Moderate; couple leaves dinner for portraits and toasts move later
Coverage impact All priority moments are mapped, but rooftop setup is covered only after primary arrival Strongest setup proof and vendor documentation; protects golden-hour start
Vendor risk Medium because the venue must complete enough setup before primary arrival Lower visual-documentation risk but higher staffing and coordination complexity
Catering risk Medium until toast window and meal sequence are approved Lower pre-portrait collision risk; post-portrait toast timing still requires approval
Cost exposure Low unless transport, accessibility, or coverage changes are required Medium to high due to second coverage role and contract extension
Reversibility High; most changes involve communication, shot-list control, and cue order Medium; staffing and contract changes may have cancellation or amendment costs
Primary failure mode Guests arrive early, setup is not photo-ready, or toasts overrun the portrait release Added staffing is not approved, coverage extension is unavailable, or dinner becomes too prolonged
Alignment with stated priority Strongest Secondary
Recommended status Recommended Contingency option when production documentation outweighs cost and guest-flow simplicity

13. Final Control Check
Control category Status Control finding
Hard constraints PASS HMU end, photography coverage, check-in, ceremony, city-hall photo limit, rooftop access, doors, final seating, portrait time, and photography end are each represented once in the master timeline
First-look feasibility CONDITIONAL BLOCKER ACCEPTED Location and prep-to-city-hall travel remain unverified; approved fallback is relocation near city hall
City hall-to-rooftop travel PASS WITH RANGE Departure at 3:35 PM produces a calculated 4:00–4:15 PM arrival window using the supplied 25–40-minute range
Rooftop setup CONDITIONAL Legal access is represented at 3:30 PM, but setup durations and photo-ready handoff remain open
Guest movement CONDITIONAL Early-arrival conflict is identified; 5:00 PM arrival communication and holding arrangements require approval
Meals and seating PARTIAL PASS 5:00 PM doors and 5:20 PM final seating are protected; dinner-service start and interruption rules remain open
Accessibility OPEN HIGH-RISK GAP No accessible transport or route details have been supplied
Buffers PARTIAL PASS Thirty-minute readiness reserve and 45–60-minute rooftop-detail window are calculated; portrait-transition duration is unknown
Coverage CONDITIONAL First look, family portraits, ceremony exit, rooftop details, toasts, and 6:15 PM portraits are mapped; video is unassigned and toast duration remains open
Handoffs PASS BY ROLE HMU, photographer, transport, city hall, rooftop, catering, emcee, guest-flow, and accessibility handoffs have assigned role owners
Rain contingency CONDITIONAL Covered terrace is identified, but threshold, capacity, setup, lighting, sound, and dry route require confirmation
Photographer hard end PASS 7:00 PM appears once; no coverage is assumed afterward
Venue curfew and strike OPEN GAP Hard end and strike requirements are missing and must not be invented
Duplicate event blocks PASS The recommended master contains one ceremony, one family portrait block, one rooftop detail block, one toast sequence, and one golden-hour portrait block
Remaining blockers EXPLICITLY OWNED Every unresolved blocker has an owner, corrective path, and confirmation deadline
The master timeline should not be released to vendors until the first-look route, family shot list, guest movement, accessibility, catering sequence, rain trigger, and venue hard end are confirmed.
