Occasion diagnosis · TT-TP-001
Before the evening buys another floral, diagnose the gathering.
Thistle Pulse ranks friction — arrival, path, sight, light, service, weather — then names one reversible test. It does not score taste. It does not invent a shopping list. Unknowns stay unknown.

Six conditions
Rank the evening, not the mood board.
Journey
Arrival
Can a guest find themselves, enter without apology, and land?
Bottlenecked → Welcoming
Venue
Flow
Can the evening move from one beat to the next without a jam?
Gridlocked → Clear path
Atmosphere
Sight
Can people see who they came with, the host, and the thing that matters?
Blind → Present
Atmosphere
Light
Does the light still serve people after the photographs are done?
Hostile → Layered
Production
Service
Can food, drink, and program actually happen in this room?
Impossible → Workable
Production
Contingency
If weather, overflow, or a curfew arrives, does the evening have somewhere to go?
One-way bet → Recoverable
See a reading first
A garden wedding with no rain plan.
Five demonstrations live in this browser. This is the one people search for: outdoor ceremony, pretty lawn, a sentence about a tent.
The answer
Contingency friction
Name one reversible fallback and walk it once — weather, overflow, or curfew.
Reason
The fallback is a sentence, a tent that does not exist, or nothing at all.
Caveat
Most fields are known; ranking is stable enough to act on.
Next
Name the most likely interruption: rain, wind, heat, overflow, curfew, or a late vendor. Write what currently happens.
Realistic examples
Load a situation, not a blank form.
Outdoor · 100–180 · evening
Garden wedding, no rain plan
The lawn is beautiful. Weather still has a vote.
Open reading
Indoor · 50–100 · standing
Pinched cocktail foyer
Everyone arrives at once. The pretty table is in the only door.
Open reading
Indoor · seated dinner
Dinner that kills conversation
The tablescape wins the photograph. No one can see across it.
Open reading
Mixed · evening · garden + barn
Barn that goes dark
String lights for the portraits. Plates and faces after 8pm.
Open reading
Indoor · life safety
Safety-flag path
One exit, 150 people. Not a floral problem.
Open reading
Pulse
Diagnose this occasion. Friction ranking, reversible test, fail-closed on safety.
Catalog
Venue Intelligence
Search rooms that can actually host the evening. Not a mood. A catalog with constraints.
Working plan
Atmosphere OS
After diagnosis: sequence, production, the plan you can walk. Pulse hands off a packet. Inspect it first.
Why not a spreadsheet, or a generic model.
Friction, never taste
The ranking is on the page: what scored, why it outranked the rest, what was unknown.
Holding is a valid result
If nothing is failing, Pulse will not invent a shopping list. That is the product.
Fail-closed on safety
Blocked exits and occupancy are not floral problems. Diagnosis withholds.
