1. A fifteen-turn live QuoteGraph replay

Read this first. This is a complete passing provider-backed run with QUOTE_GRAPH_CURRENT_DATE frozen to 2027-06-01. The model wording may vary; catalog resolution, coverage policy, calculated premiums, state transitions, and the final completed state are the durable contracts.

Run it yourself

cd ezgraph-demo
npm run test2:quote-graph

The script sets USE_ENV=1 KEEP_SESSION=1. The test sends all fifteen turns through one retained session, judges each response semantically, and inspects the final node-owned state. Without USE_ENV=1 it is skipped; with it, it needs working provider credentials.

1 · driver stage greeting

You
Hi, I'd like a quote for my car insurance.

Bot
Absolutely — I can help with that.

What’s your full name?
2 · name and birth date

You
Jamie Rivera, born April 12, 1993.

Bot
Thanks, Jamie. What state is your driver’s license issued in, and is it valid or a learner’s permit?
3 · driver capture advances to vehicle

You
Licensed in Oregon, valid license, for about 10 years.

Bot
Thanks — I’ve saved Jamie Rivera, born 1993-04-12, with a valid Oregon license and 10 years licensed.

What’s the vehicle’s year, make, and model?
4 · trim disambiguation

You
It's a 2019 Toyota Camry.

Bot
I found a few 2019 Toyota Camry trims. Which one is yours: LE, SE, or XSE?
5 · resolved vehicle asks usage

You
The SE trim.

Bot
Got it — 2019 Toyota Camry SE.

Do you own it, finance it, or lease it? And about how many miles do you drive per year?
6 · ownership and mileage

You
I finance it and drive about 12,000 miles a year.

Bot
Thanks. Where is it usually parked overnight: garage, driveway, or street?
7 · vehicle capture advances to history

You
In my driveway.
Bot
Sure — I just need two things:
1. Do you currently have auto insurance?
2. In the past 12 months, did your coverage lapse at any point?
Also, please list any incidents in the last 5 years with the month as YYYY-MM, or say “none.” Categories are:
- at-fault accident
- not-at-fault accident
- violation (like a speeding ticket)
- comprehensive claim (theft, glass, weather, animal damage)
8 · insurance status

You
I'm insured today and had no lapse in the past year.
Bot
Thanks. Any incidents in the last 5 years? Please list the month as YYYY-MM for any:
- at-fault accident
- not-at-fault accident
- violation
- comprehensive claim
“None” is perfectly fine.
9 · history capture advances to coverage

You
Just one speeding ticket in March 2026, nothing else.

Bot
Since the Camry is financed, it needs both collision and comprehensive coverage.

Which liability level would you like: state minimum, standard, or premium? And would you like $250, $500, or $1,000 deductibles for collision and comprehensive?
10 · liability selection

You
Standard liability, please.

Bot
You got it. Since it’s financed, I still need deductibles for both collision and comprehensive.

Would you like $250, $500, or $1,000 for each?
11 · lender rule blocks liability-only

You
Can I skip collision and comprehensive entirely?

Bot
Because the car is financed, collision and comprehensive are required, so you can’t skip them entirely.

Which deductibles would you like for collision and comprehensive: $250, $500, or $1,000 each?
12 · deductibles and extras

You
Fine, $500 deductibles for both, and add rental reimbursement but no roadside.

Bot
Got it. What date would you like the policy to start? It can start today through 60 days from today.
13 · coverage capture presents quote tiers

You
Start it on June 15.
Bot
Here are your quote options, starting on June 15, 2027:
1. Saver — $99.96/month
  - Liability: State-minimum
  - Deductibles: $1,000 collision / $1,000 comprehensive
  - Extras: None
2. Selected — $140.43/month
  - Liability: Standard
  - Deductibles: $500 collision / $500 comprehensive
  - Extras: Rental
  - Recommended based on your choices
3. Shield — $182.17/month
  - Liability: Premium
  - Deductibles: $250 collision / $250 comprehensive
  - Extras: Rental and roadside
You can:
- Pick a tier — for example, “I’ll take Selected”
- Adjust the quote — for example, “What if my deductible were $1,000?”
- Start over on coverage — and we can rework the choices from scratch
14 · deductible what-if adjustment

You
What would it cost if both deductibles were $1000?
Bot
Here is the updated quote:
1. Saver — state-minimum liability, $1000/$1000 deductibles, no extras: $99.96/mo
2. Your selection — standard liability, $1000/$1000 deductibles, rental: $130.49/mo
3. Shield — premium liability, $250/$250 deductibles, rental + roadside: $182.17/mo Adjust anything else, accept a tier, or rework the coverage.
15 · acceptance completes the quote · completed

You
Accept my selected option, please.

Bot
You’re all set — your selected coverage (Your selection) is locked in at $130.49/month starting 2027-06-15. Your quote reference is QT-648463.

The final turn locks the current calculated tier, creates a quote reference, sets completed: true, and leaves the accepted tier in QuoteNode state.

Under the hood

The transcript shows what the customer saw. This table shows which nodes ran, which tools changed state or moved the conversation, and who wrote each reply. The replay records replies rather than tool calls, so the tool column is inferred from each reply and the node code. Turns 14 and 15 match the code's templates word for word.

Turn	Customer	Nodes	Tool and result	Reply written by
1	Hi, I'd like a quote…	DriverNode	—	model
2	Jamie Rivera, born April 12, 1993.	DriverNode	—	model
3	Licensed in Oregon, valid license, for about 10 years.	DriverNode → VehicleNode	`capture_driver` → `go(VehicleNode)`	model (VehicleNode)
4	It's a 2019 Toyota Camry.	VehicleNode	`resolve_vehicle` → `stay()` with three trims	model
5	The SE trim.	VehicleNode	`resolve_vehicle` with a trim → `stay()`, one vehicle resolved	model
6	I finance it and drive about 12,000 miles a year.	VehicleNode	—	model
7	In my driveway.	VehicleNode → HistoryNode	`capture_vehicle_use` → `go(HistoryNode)` + stage message	model (HistoryNode)
8	I'm insured today and had no lapse in the past year.	HistoryNode	—	model
9	Just one speeding ticket in March 2026, nothing else.	HistoryNode → CoverageNode	`capture_history` → `go(CoverageNode)` + stage message	model (CoverageNode)
10	Standard liability, please.	CoverageNode	—	model
11	Can I skip collision and comprehensive entirely?	CoverageNode	none needed; the rule is in the prompt and enforced in code	model
12	Fine, $500 deductibles for both…	CoverageNode	—	model
13	Start it on June 15.	CoverageNode → QuoteNode	`select_coverage` → rating → `go(QuoteNode)` + stage message	model (QuoteNode)
14	What would it cost if both deductibles were $1000?	QuoteNode	`adjust_quote` → rating → `direct(text)`	code
15	Accept my selected option, please.	QuoteNode → end	`accept_quote` → `finish(text)`	code

Four things are worth noticing before the lessons take the graph apart:

Most turns call no tool. A stage's model keeps asking questions until it has everything its tool needs. State changes only when a handler accepts a complete, valid submission.
A stage change happens inside one turn. On turns 3, 7, 9, and 13 one node saves its facts and returns go(), and the next node writes the reply. The customer never sees a “moving on” message from the old stage.
Every price comes from code. The rating engine priced the tiers on turn 13, and the model presented them from JSON. On turn 14 the model only chose adjust_quote; the numbers and the wording came from code, with no second model call.
Acceptance is a business event, not a sentence. Turn 15 completes because accept_quote found selected in the saved tiers. The confirmation, premium, start date, and reference number are all code-owned.

Two small inconsistencies are visible too. The model called the middle tier “Selected” on turn 13, while the code's label on turn 14 is “Your selection”. And the confirmation on turn 15 reads “your selected coverage (Your selection)”. Lesson 9 explains both.

2. Graph, state, and ownership maps the nodes and durable values behind the replay.
