Clara Bench

Every benchmark run is a row: what changed, on which set, how Clara scored, and what Fede thinks.

v1 prototype · 40 runs · design: benchmark framework, section 8

In one line: 40 runs so far, 10 of them exploratory (run before the frozen set exists). Judge: Fable 5.1 only. From v1 on: quality is pairwise against the baseline; never-do rules are code checks that fail on any.

Review set 3: tenant texts, today's Clara vs Opus 5.5 on the decomposed prompt (Oct 26)

The question: on real tenant texts from the last week, does New Clara (the decomposed prompt on Opus 5.5) make the same call as today's Clara (today's prompt on Sonnet 5), and where they differ, who is right? The answer: they make a different call on 19 of 46 texts, mostly because New Clara goes silent far more often (28 vs 12), including on a plain repair report (#1), so your verdicts on the 19 below decide it, not the judge.

On 46 tenant textsClara todayNew Clara
Replies (would send now)74

Stays silent1228
Different call from the other19 of 46

In 16 of the 19, New Clara stays silent where today's Clara holds (12) or replies (4). In the other 3, New Clara answers herself where today's Clara only passes it to the team (#7, #14, #19). Western Slope and Situs Group, Oct 20 to 25; texts from the night shadow run, replayed on both. 50 more texts were left out because the sender is not an active tenant at that home (no reply from either). No judge score here: the judge has been wrong before, so your call is the column.

How to grade: reply in chat by number, for example "3 today right", "7 new right", "12 both wrong: should file a work order". Drafts are shown exactly as each Clara wrote them, dashes included. #20 to #25 are controls where both made the same call, to check the agreements are right too. Spanish texts are left in Spanish.

Thank you! The only time I'm unavailable today is 1-2p. For the pests, Marcus did come out and spray. He told me to wait 2 weeks to assess effectiveness. So far, it seems effective outside but I'm seeing continued activity outside.

Got it, Stephanie — I've noted you're free today except 1-2pm for the Sparky visit on the light switch panel. And I've logged that the pest treatment seems to be working inside but you're still seeing activity outside, so that's on record for the 2-week check-in.

That's frustrating, Shari, especially since there are more bugs now than before the spraying.

Step 1: today's leasing prompt split into four pieces, on production's own model (Oct 27)

Does splitting the prompt change what Clara writes? No: every measure is inside production's own spread.

51 real first emails, all on claude-sonnet-5 (production's leasing model). Production ran three times to measure how much it differs from itself; the split (today's text word for word under four headers) ran once. Full numbers: run detail.

On 51 first emailsProduction, 3 runsSplit
Held by send checks26 / 19 / 2122
Invented facts9 / 8 / 89
Em dash4 / 2 / 35
Told the team0 / 1 / 10
Same email as production run A (judge)16 and 18 of 5120 of 51
Emails where this run loses to both others5 / 4 / 64

One count is one over the bar written before the run: the split saved the prospect's details on 30 emails, run A on 25 (allowed gap 4); the three production runs spread 25 to 29.

Fede's graded examples (the floor)

Five of Fede's seven graded first emails can be rebuilt (n27 and n33 cannot). His verdict was on an earlier comparison; the question here is only whether the split falls below production on them. Judge: Fable 5.1, both orders.

ExampleFede's verdictProduction same as itself (of 3 pairs)Split same as production (of 3)Production better than split (of 3)Split better (of 3)Result
n25"production better"1 of 30 of 30 of 33 of 3Not below. A stale case: a tour is already booked for Oct 7 and every arm ignores it; the judge prefers the split for not quoting new times over the booking.
n26"production better (tone)"1 of 32 of 32 of 30 of 3Close: production wins 2 of 3 against the split, 1 of 3 against itself; the fresh-run emails are near word for word the same.
n29"both wrong"0 of 31 of 30 of 32 of 3Not below. Production runs disagree with each other here on every pair.
n30"today better" (the Opus arm said "I'll check with the team" on the special)0 of 31 of 30 of 30 of 3Not below; both quote the special and offer times.
n34"both wrong" ("we always need to offer real availability")0 of 30 of 32 of 31 of 3Same as noise: one production run beats another on 2 of 3 pairs here too.

The four emails outside production's spread

These are the emails where production matched itself but the split did not. The emails below are a fresh run (Oct 27, same model, nothing sent), because the scored emails were lost; the line under each says what the judge saw in the scored run. Names kept, phones and emails removed. How to grade: reply in chat by number, for example "3 today" or "1 tie".

What the judge saw in the scored run: In the scored run the split looked up units, added baths, size and special terms that production never gave (a 12-month lease, an October 31 deadline), and named the home by its street address. Production did none of that in 4 of 4 runs. In this fresh run the split again names it by its street address and pastes the special in capitals.

Hi Tristan,

Thanks for your interest in Camellia Apartments, we have studios available now running $950-$1,000/mo (386-444 sq ft), with one month free on a 12-month lease, which would line up nicely with your December 2nd move-in, so let me know what you'd like to do next.

What the judge saw in the scored run: In the scored run the split used an em dash; production did not in any of its three runs. In this fresh run the split has no dash but is one long run-on sentence, and it is held.

Hi Queen,

Thanks for reaching out about Unit 206 at Camellia Apartments, it's a studio, 1 bath with 386 sq ft, available now at $1,000/mo, and right now new 12 month leases also come with one month free. We do offer 6 month leases here, at the same rental rate as a 12 month lease, so that timing works fine. Beyond rent, water, sewer, trash and heat are billed monthly through a third party, Conservice, along with your rent, and studio residents have typically paid around $40 to $50 a month depending on usage. Electric is your own account with Xcel Energy and internet is your own as well. On site parking runs $80/mo for a surface spot or $95/mo for a garage spot, though it's currently full with a waitlist, in the meantime the nail salon next door rents overflow spots for $100/mo through our office. There's no admin fee, and the application fee is $38 per applicant. You're all set for your tour on Tuesday, October 13 at 2:30 PM at Camellia Apartments, 1235 Grant Street, looking forward to seeing you then.
Hi Queen,

Yes, we do offer 6-month leases here, at the same rate as 12-month leases. If a 12-month term works better for you, we're also running a move-in special of one month free right now.

On monthly costs beyond rent: water, sewer, trash, and heat are billed through a third-party company, Conservice, and studio residents typically see around $40 to $50 a month on that bill depending on usage. Electric is your own account with Xcel Energy, and internet is separate as well. Parking runs $80/mo for a surface spot or $95/mo for garage, though on-site parking is full right now, so you'd be added to the waitlist, with overflow parking available next door at $100/mo in the meantime. There's no admin fee here.

I have tour times available Friday, October 30 between 10:15 AM and 1:45 PM, or Monday, November 2 between 9:00 AM and 4:45 PM, would either of those work for you to come see it?

Good news on the lease length too: we're currently offering longer terms of 14 to 18 months as a promotion, so an 18-month lease works here. As for your pet, cats and dogs are welcome with a $300 pet deposit and $35/month pet rent per pet — since yours is listed as "Other," I'd want to confirm the specific type works with the policy, and that's easy to sort out at your tour.

Our standard pet policy covers cats and dogs (two-pet limit, $300 refundable pet deposit, $35/month pet rent per pet), and I want to make sure that's the right fit for yours.

For the tour, tomorrow evening isn't an option, but I do have Friday, October 30 between 1:30 and 5:30 PM, or Saturday, October 31 between 10:00 AM and 2:30 PM — would either of those work, and if so, what time within the window?

Hi Queen,

Thanks for your interest in the studio at Camellia Apartments, 1235 Grant Street. Unit 206 is a studio, 1 bath, 386 sq ft, at $1,000/mo, available now. Camellia offers both 6-month and 12-month lease terms at the same rental rate, and right now 12-month leases come with one month free.

On fees beyond base rent: utilities aren't included in rent. Water, sewer, trash, and heat run through a third-party billing company, Conservice, and studio residents have typically paid around $40 to $50 a month, though that depends on usage. Electric is your own account with Xcel Energy, and internet is also your own to set up. On-site parking runs $80/mo for a surface spot or $95/mo for garage, though it's currently full and new residents go on a waitlist; in the meantime, overflow parking is available next door at the nail salon for $100/mo, arranged through the leasing office. There's no admin fee.

You're all set for your tour Tuesday, October 13 at 2:30 PM at 1235 Grant Street. Looking forward to seeing you then!
Hi Queen,

Thanks for reaching out about Camellia Apartments. Unit 206 is a studio, 1 bath with 386 sq ft at $1,000/mo and it's available now, which works well with your October 14 move in. We offer both 6-month and 12-month lease terms at the same rental rate, and 12-month leases also come with our current move-in special of 1 month free (new leases only). Beyond rent, water, sewer, trash, and heat are billed monthly through a third-party company called Conservice (that first bill usually shows up about a month after move-in, and other studio residents have seen those run around $40 to $50 a month based on usage), electric and internet are separate accounts you'd set up yourself, parking is $80/mo for a surface spot or $95/mo for garage (on-site parking is currently full with a waitlist, though overflow parking is available next door for $100/mo through our office), and there's no admin fee.

I'd love to get you in to see it: I have Friday, October 30 between 10:15 AM and 1:45 PM, or Monday, November 2 between 9:00 AM and 4:45 PM. Which works better for you?

Hi Queen,

Unit 206 is a studio, 1 bath, 386 sq ft, at $1,000/mo, available now, which lines up well with your October 14 move in.

On lease length: yes, we offer both 6 month and 12 month lease terms at Camellia, and they're at the same rental rate either way.

As for monthly costs beyond rent, utilities aren't included in the base rent. Water, sewer, trash, and heat are billed monthly through a third party, Conservice, to your resident portal (that first bill usually shows up about a month after move in). Electric is your own account with Xcel Energy, and internet is set up on your own as well. There's no admin fee. Parking is available for $80/mo surface or $95/mo garage, though on site parking is full right now, so new residents go on a waitlist. In the meantime, the nail salon next door rents spots to Camellia residents for $100/mo, which our office can help set up.

Looking forward to seeing you Tuesday, October 13 at 2:30 PM for your tour at 1235 Grant Street. Let me know if anything comes up before then.
Hi Queen,

Thanks for your interest in the studio at Camellia Apartments! To answer your questions: yes, we offer 6-month lease terms here, and they're at the same rental rate as a 12-month lease, so there's no price difference either way.

On monthly costs beyond rent: utilities aren't included in rent. Water, sewer, trash, and heat are billed monthly through our third-party biller, Conservice (studio residents typically see around $40 to $50 a month, depending on usage). Electric is your own account with Xcel Energy, and internet is also set up individually, so those aren't on your rent statement. Parking is $80/month for a surface spot or $95/month for a garage spot (on-site parking is currently full, so new residents go on a waitlist, though there's an overflow option next door at $100/month arranged through our office). Since you don't have a pet, there are no pet-related fees to worry about. The security deposit for a studio is $300, and the application fee is $38 per applicant with no separate admin fee.

You're all set for your tour this Tuesday, October 13 at 2:30 PM, where I can walk you through 206 and answer anything else in person. Looking forward to it!

You already have tours booked at both. You'll see 2841 Morningside Court tomorrow, Tuesday, September 29 at 5:30 PM, and 2980 Emerald Circle on Friday, October 2 at 1:30 PM. A leasing agent will meet you at each home.

Hi Queen,

Unit 206 is a studio, 1 bath with 386 sq ft, available now at $1,000/mo. We offer both 6-month and 12-month leases at the same rate, and if you go with a 12-month lease you'll get one month free. Utilities aren't included in rent: water, sewer, trash, and heat run through a billing company called Conservice and show up on your portal alongside rent (studio residents have typically paid around $40 to $50 a month there), while electric and internet are your own accounts with Xcel Energy and the internet provider of your choice. On site parking runs $80/mo for a surface spot or $95/mo for a garage spot, though it's full right now and new residents go on a waitlist; in the meantime, overflow parking is available next door at the nail salon for $100/mo. There's no admin fee. I have Friday, October 30 between 10:15 AM and 1:45 PM, or Monday, November 2 between 9:00 AM and 4:45 PM, would either of those work for a tour?
Hi Queen,

Thanks for reaching out about Unit 206 at Camellia Apartments. It's a studio, 1 bath with 386 square feet, available now at $1,000 per month. We do offer 6 month leases here, at the same rate as our 12 month leases, so that works for your timeline. Rent doesn't include utilities: water, sewer, trash and heat come through a monthly Conservice bill, while electric and internet are set up in your own name with Xcel and your internet provider. Parking runs $80 a month for a surface spot or $95 for a garage spot (on-site parking is on a waitlist right now, but overflow parking is available next door for $100 a month). If a 12 month lease ever makes more sense for you, we're also running one month free on new 12 month leases.

Would Friday, October 30 between 10:15 AM and 1:45 PM, or Monday, November 2 between 9:00 AM and 4:45 PM work for a tour?

Judge (claude-fable-5-1, both orders): order A picked 1: Both ignore the already-booked tour, but Email 1 answers the fee question more completely with the utility ballpark and no-admin-fee detail, while Email 2 is only slightly more readable. / order B picked 2: Both correctly cover Unit 206, the 6-month lease, utilities, parking and the special while wrongly ignoring the booked tour, but Email 2 answers the fees question more fully with the no-admin-fee note and the sourced utility ballpark. Drops: Studio residents typically pay around $40–50/mo for the Conservice utilities; There is no admin fee (addresses the 'other community fees' question)

Hi Amy,

Just to let you know, 2978 Emerald Circle is no longer available. The home at 2841 Morningside Court is still open though, and you already have that tour on the books for tomorrow, Tuesday, September 29th at 5:30 PM, so your partner is more than welcome to come along too.

Once you've both had a chance to see it, if you'd like to apply, the application for 2841 Morningside Court was already sent your way (Tuesday, September 29) — just check your email, spam folder included, and let me know if it hasn't turned up.
Hi Amy,

The home at 2978 Emerald Circle is no longer available, so your tour there on Friday, October 2 at 1:00 PM can't happen as planned.

You still have tours booked at two homes that are available. Tomorrow, Tuesday, September 29 at 5:30 PM, you're seeing 2841 Morningside Court, a 4-bedroom, 2-bath home at $2,300/mo. On Friday, October 2 at 1:30 PM, you're seeing 2980 Emerald Circle, a 4-bedroom, 2.5-bath home, also at $2,300/mo.

If you and your partner like one of them, you'll each fill out an application. The fee is $40 per applicant.

Would you like me to cancel the 1:00 PM tour at 2978 Emerald Circle?

Hi Queen,

Unit 206 is a studio with 1 bath, 386 square feet, at $1,000/mo and it's available now, which lines up well with your October 14 move in.

On lease length: yes, Camellia offers both 6 month and 12 month terms at the same rental rate. One thing worth flagging since you're weighing the shorter term: our current move in special, one month free, only applies to new 12 month leases.

Beyond rent, here's what else factors in monthly. Parking is $80/mo for a surface spot or $95/mo for garage (both are full right now, so new residents go on a waitlist, though the leasing office can also set you up with overflow parking next door at the nail salon for $100/mo). Water, sewer, trash and heat are billed monthly through our utility company, Conservice, and for a studio that typically runs around $40 to $50/mo; electric is your own Xcel Energy account and internet is set up on your own as well, so those aren't included in rent.

You're all set for your tour Tuesday, October 13 at 2:30 PM at Camellia Apartments, 1235 Grant Street. Looking forward to meeting you then!

We offer both 6-month and 12-month leases at the same rate, so a 6-month term works fine for your October 14th move-in.

We're also running one month free on new 12-month leases, if that's something you'd want to weigh against the 6-month term. I have Friday, October 30th between 2:15 and 4:45 PM, or Monday, November 2nd between 9:00 AM and 4:45 PM for a tour, would either work for you?

Hi Carmen,

Unit 300 at Pomona Park Townhomes (624 Eisenhauer Street) is no longer available. We don't have a studio open there right now either, but there is a 3-bedroom, 2.5-bath townhome with 1,450 sq ft available now from $2,395/month, and it comes with an in-unit washer and dryer.

Would you like to come see it? I have Friday, October 30 between 2:00 PM and 5:30 PM, or Saturday, October 31 between 10:00 AM and 2:30 PM, either one works for a tour.
Hi Carmen,

Thanks for reaching out about Pomona Park Townhomes. Unit 300 at Pomona Park Townhomes (624 Eisenhauer Street) is no longer available. There's no studio open there right now, but there is a 3-bedroom, 2.5-bath townhome with 1,450 sq ft, starting at $2,395/mo.

One of the 3-bedrooms is $2,495 a month and has a move-in special: if you sign a 12-month lease by October 31, 2026, your first month's rent is half off.

If you'd like to see it, I can show you around Friday, October 30 between 2:00 PM and 5:30 PM, or Saturday, October 31 between 10:00 AM and 2:30 PM. Which day works better for you?

Hi Amy,

The home at 2978 Emerald Circle isn't available right now, so a viewing there isn't possible at the moment. You'd also been looking at 2841 Morningside Court, which is open now, a 4-bedroom home at $2,300/mo, and you already had your tour there on Tuesday, September 29th, so I'd love to hear what you and your partner thought of it.

As for applying, you and your partner would each submit your own application, with a $40 application fee per applicant.

Let me know how the Morningside Court visit went and whether you'd like to move forward!
Hi Amy,

Thanks for writing. The home at 2978 Emerald Circle is no longer available, which means your Friday, October 2 tour there at 1:00 PM can't go ahead. Would you like me to cancel it for you?

You already have tours booked at two open homes. Tomorrow, Tuesday, September 29 at 5:30 PM, you'll see 2841 Morningside Court, a 4-bedroom, 2-bath for $2,300/mo. On Friday, October 2 at 1:30 PM, you'll see 2980 Emerald Circle, a 4-bedroom, 2.5-bath for $2,300/mo. Please ignore the square footage I gave earlier for Morningside Court.

If you and your partner like one of them, you'll each fill out an application. It's $40 per applicant, and you'll each need two forms of ID and proof of income. Once everything is in, you'll hear back within 1 to 2 business days.

Inquiry: <user_message> Hello, I'm interested in a studio apartment (unit 206/606) at Camellia Apartments and am looking to move in around October 14. Do you offer 6-month lease options? I'd also like to know what additional monthly fees are charged besides the base rent, such as utilities, parking, trash, or other community fees. Thank you!. Pet Description: no pets. Pet Type: None. Lease Length Months: 1. </user_message>

Production reference (held)claude-sonnet-5 (held)
Hi Queen,

Thanks for reaching out about Camellia Apartments. Unit 206 is a studio with 1 bath, 386 sq ft, available now at $1,000/mo.

On lease length: we offer both 6-month and 12-month terms at the same rental rate, so a 6-month lease is available on this home. New 12-month leases currently also come with one month free, in case that's worth considering alongside the 6-month option.

As for monthly costs beyond rent: parking is $80/mo for a surface spot or $95/mo for a garage spot (on-site parking is full right now, so new residents go on a waitlist, with overflow parking available next door for $100/mo if needed sooner). Water, sewer, trash, and heat are billed monthly through our utility company, Conservice, based on usage, typically running around $40 to $50/mo for a studio, while electric and internet are set up separately in your own name with Xcel Energy and your internet provider. There's no admin fee, and since you mentioned no pets, there's nothing additional on that front.

You're all set for your tour Tuesday, October 13 at 2:30 PM at Camellia Apartments, 1235 Grant Street. Looking forward to seeing you then!
Hi Queen,

Thanks for reaching out about Unit 206, it's available now, a studio, 1 bath with 386 sq ft at $1,000/mo, which lines up well with your October 14 move-in.

Yes, we offer 6 month leases, at the same rate as a 12 month lease. If a 12 month term works better for you, we're also running one month free on new 12 month leases right now.

Beyond rent, utilities aren't included: water, sewer, trash and heat run through our billing company, Conservice, and typically land around $40 to $50 a month for a studio, starting about a month after move-in. Electric and internet are your own accounts (Xcel Energy for electric). Parking runs $80/mo for surface or $95/mo for garage, though both are full right now, so new residents go on a waitlist, and in the meantime overflow parking is available next door at $100/mo, arranged through our leasing office.

I have Thursday, October 29 between 9:00 AM and 11:45 AM, or Friday, October 30 between 9:30 AM and 1:45 PM to show you Unit 206, would either window work for you?

Inquiry: <user_message> hi, would you be available tomorrow evening for a tour. I am interested in:363 Ember Ln. Pet Description: A pet. Pet Type: Other. Lease Length Months: 18. </user_message>

Production reference (held)claude-opus-5-5
Hi,

363 Ember Ln is a 3 bed, 2 bath home at 1,289 sq ft for $2,550/mo, and it comes with our Grand Opening Special: 6 weeks free rent plus water, sewer and trash included for your first year (you'd just cover electricity and internet), running through October 31 or while supplies last. On the 18 month lease, that actually falls right in the promotional range we're offering right now (14 to 18 months), so that works. As for the pet, cats and dogs are welcome here with a $300 refundable pet deposit and $35/month pet rent — what kind of pet do you have so I can make sure it fits?

Tomorrow evening isn't open on the calendar, but I do have Thursday, October 29 at 5:00 PM or Friday, October 30 at 5:00 PM for a tour of 363 Ember Ln — would either of those work for you?
I didn't book a tour. Tomorrow evening (Friday, October 9) has no open times, so the email offers the two latest windows on the calendar for 363 Ember Ln: Thursday, October 29 between 2:30 and 5:30 PM, or Friday, October 30 between 1:30 and 5:30 PM. Those are weeks out because they're the earliest times the calendar returned. The email doesn't give a reason.

Here's what the email says:

- **Opening:** it greets Michael and names 363 Ember Ln: 3 bed, 2 bath, 1,289 sq ft, $2,550/mo. Its Grand Opening Special goes beside the rent: 6 weeks free plus water, sewer and trash for the first year, until October 31 or while supplies last.
- **18-month lease:** it says the standard term is 12 months and that 14 to 18 months is currently offered as a promotion. That covers 18 without promising it.
- **Pet:** their card only says "Other," so the email doesn't assume it's an ordinary pet. It gives the cat and dog policy (up to two, $300 refundable deposit, $35 a month per pet) and asks what kind of pet it is. If the answer isn't a cat or dog, whether it's allowed isn't on file.

Michael's name, the home he wants, the pet note and the 18-month request are now on his record.

Two earlier replies in this thread are wrong, and I didn't correct them. The first said 2980 Emerald Circle was no longer available. The current record shows it open, so 2978 was the one that's gone. Those replies also listed 363 Ember Ln at $2,795 instead of $2,550, and 2863 Florida Street as open, though it isn't available until November 2. This email gives the right price for 363 but doesn't call out the earlier mistakes. You may want to send Michael a correction.

Hi Ronald,

The home at 374 Ember Lane is open now, a 3-bedroom, 2-bath with 1,228 sq ft, from $2,300/mo; right now it also comes with a Grand Opening Special of 6 weeks free rent plus water, sewer and trash included for your first year (electricity and internet are on you), through October 31 or while supplies last, and we're also offering longer lease terms of 14 to 18 months as a promotion, so an 18-month lease works fine here. Pets are welcome, with a $300 refundable pet deposit and $35 per pet per month in pet rent, so just let me know what kind of pet you have and I can confirm the details for you.

I'd love to get you in to see it: I have Thursday, October 29 between 9:30 AM and 12:00 PM, or Friday, October 30 between 10:00 AM and 12:30 PM, whichever works better for you.

Hi Will, good to hear from you again! Right now we have unit 220 open, a one-bedroom at $1,200/mo, 556 sqft. We're also running one month free on new 12-month leases.

I don't have any update yet on a west-facing, floor 3+ unit beyond what's already been flagged with the team. Want to come take a look at 220 in the meantime? I have Monday between 9:00 AM and 11:45 AM, or between 1:00 PM and 4:45 PM, whatever works best for you.
I wrote Will a short first email. Nothing was booked, and nothing went to the team.

**What the email says:**
- **Unit 614:** no longer available.
- **What's open now:** a 1-bedroom, 1-bath, 556 sq ft at $1,200/mo, with 1 month free on a new 12-month lease. I didn't name the unit number.
- **Parking:** I answered this because his notes mention it. On-site spots are full and new residents join a waitlist. Until then, the nail salon next door rents spots to residents for $100 a month.
- **Tour times:** Thursday, October 29 between 9:00 AM and 11:45 AM, or Friday, October 30 between 9:30 AM and 1:45 PM.

**Things to check:**
- **Tour dates:** those dates come from the inquiry card. My calendar check for Monday, October 5 showed openings from 9:00 AM to 11:45 AM and 1:00 PM to 4:45 PM. Both offered dates are after his October 24 move-in, so you may want to offer him Monday instead.
- **Earlier wrong promises:** past emails told Will that units 420 and 524 were available when they had been rented. They also said someone would follow up "tomorrow" on the west-facing question, and that 614 was confirmed for a 1 PM tour even though the booking tool refused it. This email doesn't correct any of that, and I have no direction-facing data to answer his question.
- **No tour on file now:** the September 30 tour has passed and nobody recorded whether he came.

I saved his wants to his record: west-facing, level 3 or higher, and parking.

Hi Emma,

Thanks for reaching out about Unit 405 at Pomona Park Townhomes (624 Eisenhauer Street), it's available now, a 3-bedroom, 2.5-bath with 1,528 sq ft at $2,495/mo; there's no 1-bedroom open there right now. It also comes with a move-in special: sign a 12-month lease by October 31, 2026, and your first month's rent is half off. Since you mentioned having a dog and a cat, the pet deposit is $300 total and pet rent runs $35 per pet per month. You'd also asked about Ember Estates, but that one isn't available right now.

I'd love to show you Unit 405: I have Thursday, October 29 between 10:00 AM and 12:00 PM, or Friday, October 30 between 10:00 AM and 12:30 PM. Which works better for you?

Hi Amy,

2978 Emerald Circle isn't available right now, so that one won't be in play for an application. I hope you enjoyed seeing it on your tour.

The good news is 2841 Morningside Court is open now, a 4 bed, 2 bath home at $2,300/mo, and you're already all set for your tour there tomorrow, Tuesday, September 29th at 5:30 PM. The application for it was sent to you on September 29th too, so once you and your partner have seen it, you can go ahead and apply, just check your email (and spam folder) for it.
Hi Amy,

Thanks for reaching out about 2978 Emerald Circle. That home is no longer available. Two other homes are open, and both are 4-bedrooms at $2,300/mo: 2841 Morningside Court has 2 baths, and 2980 Emerald Circle has 2.5 baths.

You already have tours booked at both. You'll see 2841 Morningside Court tomorrow, Tuesday, September 29 at 5:30 PM, and 2980 Emerald Circle on Friday, October 2 at 1:30 PM. A leasing agent will meet you at each home.

If you and your partner like one of them, the application fee is $40 per applicant, so $80 for the two of you. Each of you will need two forms of ID and proof of income. Just reply here when you're ready and I'll send the application.

Hi Ronald,

Thanks for reaching out about 374 Ember Lane, it's available now, a 3 bedroom, 2 bath home with 1,289 sq ft at $2,550/mo, and right now it comes with a grand opening special: 6 weeks free rent plus water, sewer and trash included for your first year (you'd just cover electricity and internet), running through October 31 or while supplies last.

On lease length, we're currently offering longer terms of 14 to 18 months as a promotion, so an 18 month lease works here. For pets, cats and dogs are welcome, with a $300 refundable pet deposit and $35 per pet per month in pet rent. Since your pet is listed as "Other," let me know a bit more about what kind so I can make sure that's all set.

Would you like to come see it Thursday, October 29 between 10:30 AM and 12:00 PM, or Friday, October 30 between 10:00 AM and 12:30 PM?
Hi Ronald,

Thanks for reaching out about 374 Ember Lane. It's available now: a 3-bedroom, 2-bath home with 1,289 sq ft at $2,550/mo. I hear you on the rent, and the Grand Opening Special helps with that. You get 6 weeks of free rent, and water, sewer and trash are included for your first year (you'd pay for electricity and internet). The special runs until Oct 31 or supplies last.

Our standard lease is 12 months, and right now we're offering longer leases of 14 to 18 months as a promotion. Cats and dogs are welcome here, up to two pets. What kind of pet do you have?

Parking runs $80/mo for a surface spot or $95/mo for a garage, though on site parking is full right now so new residents go on the waitlist, with overflow parking available next door for $100/mo in the meantime, and there's no admin fee.

Hi Queen,

Thanks for reaching out about Unit 206 at Camellia Apartments, it's available now, a studio, 1 bath with 386 sq ft at $1,000/mo. We do offer both 6-month and 12-month leases at the same rental rate, and right now new 12-month leases get one month free.

Beyond rent, water, sewer, trash and heat are billed monthly through our third-party provider, Conservice, based on usage; studio charges run about $40 to $50 a month. Electric is your own account with Xcel Energy, and internet is also set up in your own name. Parking is $80/mo for a surface spot or $95/mo for a garage spot, though on-site parking is full right now, so new residents go on a waitlist; in the meantime, the nail salon next door rents spots to residents for $100/mo, arranged through our office.

Ember Estates is no longer available. The 3-bedroom at Pomona Park Townhomes (624 Eisenhauer Street) is still open at $2,495/mo, and it's pet-friendly for your dog and cat. Want to grab one of the tour times I mentioned, Thursday, October 22 at 5:30 PM or Friday, October 23 between 11:30 AM and 12:00 PM?
Hi Emma,

That duplex listing is for Ember Estates, and it's not available right now. Let me know if you'd like to look at anything else and I'm happy to help.

Hi Mary Ann,

Thanks for reaching out about Ember Estates at 374 Ember Lane. A 2-bedroom isn't open there right now, but there's a 3-bedroom open now, running $2,550 to $2,795 a month. It also comes with the Grand Opening Special: receive 6 weeks free rent, plus water, sewer and trash included for your first year (you'd cover electricity and internet). That special runs through October 31 or while supplies last.

Would a 3-bedroom work for you? I can show it Wednesday, October 28 between 9:00 AM and 9:45 AM, or Thursday, October 29 between 9:30 AM and 12:15 PM, whichever is better for you.

Hi Steven,

Thanks for reaching out about Northridge Apartments at 565 Redcliff Cir, it's available now, a 3-bedroom home. Tours here are self-guided: you can go in on your own any day, any time that works for you, and I'll send you the lockbox code ahead of your visit. What day and time would you like to go see it?
I've written the first reply to Steven's inquiry. It tells him a 3-bedroom is open now at Northridge Apartments (565 Redcliff Cir) and confirms the virtual tour already on file for Sunday, September 27 at 10:00 AM, with the Zoom link.

Two things in his record don't add up:

- **Tour:** The record shows a virtual tour already booked for Sunday, even though this is his first message and he hasn't asked for one. I treated it as real and confirmed it because the record says it's booked. Someone should check how it got there, or he'll get a confirmation for a tour he doesn't know about.
- **Application:** The record says his application was sent on Sunday, September 27. Today is Friday, September 25, so that date hasn't happened yet. He didn't ask about applying, so the email doesn't mention it, but the date is probably wrong.

The email has no rent, bath count or square footage because his record doesn't list them for the 3-bedroom, and I didn't look them up.

I saved him as a lead with his name, email and the October 9 move-in date. Nothing was handed off to the team.

Unit 402 at Camellia Apartments (1235 Grant Street) is no longer available. The good news is we do have a studio open right now, running $1,150/mo. Also, just to confirm, we offer both 6 and 12 month leases at the same rental rate, so a 6 month term works fine here.

I'd be glad to get a tour set up for you. What day and time work best?
I sent Yoira a reply. Before you rely on it, you should know my June reply to her had two errors. This one fixes them, but she may still have the wrong information.

The June errors:
- **Wrong application link.** I sent her the floor-plans page on the Camellia website. This reply gives her the correct link (https://jpco.appfolio.com/listings) and asks her to use it instead.
- **Wrong wording on the special.** I said "1 month free on select apartments, restrictions may apply." The actual special is 1 month free on new 12-month leases, with none of those conditions. This reply states it correctly but doesn't point out that the earlier wording was wrong.

What the new reply says:
- Unit 402 is no longer available, but a studio is open now.
- Camellia offers 6-month and 12-month leases at the same rent. Her new inquiry asked for 6 months, so I added that the 1 month free special only applies to 12-month leases.
- She already has a tour on Monday, October 26 at 11:00 AM at 1235 Grant Street, so she doesn't need to book another. Her new inquiry asked to schedule a tour, so I didn't book a second one.

I left out a rent figure. The only prices I have are from June (studios at $1,150/mo), and the current availability info doesn't include a price.

I also added a note to her lead record that she asked about a 6-month lease. Nothing needed to go to the team.

Inquiry: <user_message> hi, would you be available tomorrow evening for a tour. I am interested in:363 Ember Ln. Pet Description: A pet. Pet Type: Other. Lease Length Months: 18. </user_message>

Production referenceclaude-sonnet-5
Hi there,

363 Ember Ln is open now, a 3 bedroom, 2 bath home at 1,289 sq ft for $2,550/mo, and it's running the Grand Opening Special: 6 weeks free rent plus water, sewer and trash included for your first year (you'd just cover electricity and internet), through October 31 or while supplies last.

On the pet: cats and dogs are welcome here with a $300 refundable pet deposit and $35/month pet rent. Since you listed the type as "Other," could you let me know what kind of pet it is so I can confirm it's covered under that policy?

On lease length: this home is currently offering longer terms as a promotion, 14 to 18 months, so an 18 month lease works here.

For an evening tour, the latest I can offer is 5:45 PM: that's open Wednesday, October 28 or Thursday, October 29. Which day works better for you?
Tomorrow evening isn't open for a tour, but I can get you in Wednesday, October 28 at 9:00 AM or Thursday, October 29 at 9:30 AM, whichever works better.

For 363 Ember Ln, it's a 3-bedroom, 2-bath home at 1,289 sq ft for $2,550/mo, and it's currently running a Grand Opening Special: 6 weeks free rent plus water, sewer, and trash included for your first year (you'd just cover electricity and internet), through October 31 or while supplies last. An 18-month lease works too, since we're currently offering promotional terms from 14 to 18 months.

On the pet, could you tell me what kind of animal it is? That'll help me give you the right details.

Inquiry: <user_message> Hello, I'm interested in a studio apartment (unit 206/606) at Camellia Apartments and am looking to move in around October 14. Do you offer 6-month lease options? I'd also like to know what additional monthly fees are charged besides the base rent, such as utilities, parking, trash, or other community fees. Thank you!. Pet Description: no pets. Pet Type: None. Lease Length Months: 1. </user_message>

Production reference (held)claude-opus-5-5 (held)
Hi Queen,

Thanks for reaching out about Unit 206, a studio at $1,000/month, available now. Camellia Apartments offers both 6-month and 12-month lease terms at the same rental rate, so a 6-month lease works fine for your October 14 move-in.

On fees beyond rent: water, sewer, trash, and heat are billed monthly through our third-party biller, Conservice (studio residents typically see about $40 to $50 a month there), while electric and internet are set up separately in your own name with Xcel Energy and your preferred provider. On-site parking runs $80/month for a surface spot or $95/month for a garage spot, though those are currently full with a waitlist; in the meantime, overflow parking is available next door at the nail salon for $100/month, arranged through our office. Since you don't have pets, there's nothing additional there.

Looking forward to seeing you Tuesday, October 13 at 2:30 PM for your tour!
I've written Queen's first email from what we have on file. The only thing still open is her "Lease Length Months: 1": nothing on file covers a 1-month lease, so I sent that question to the property team.

The email covers:
- **The unit:** Unit 206 is a studio with 1 bath, 386 sq ft, at $1,000/mo, and it's available now. It also has the 1 month free special on a 12-month new lease.
- **6-month lease:** Yes, we offer one, at the same rent as a 12-month lease. For the 1-month term, the email says "I'll check with the team and get back to you" and doesn't hint at an answer.
- **Utilities:** None are included in rent. Water, sewer, trash and heat are billed through Conservice based on usage, and studio residents have paid around $40 to $50 a month. Electric (Xcel Energy) and internet are her own accounts.
- **Parking:** Surface spots are $80/mo and garage spots are $95/mo, but on-site parking is full, so she'd go on a waitlist. Until then, the nail salon next door rents spots for $100/mo through the leasing office.
- **Admin fee:** There isn't one.
- **Tour:** She already has a confirmed tour for Tuesday, October 13 at 2:30 PM at 1235 Grant Street, so the email ends on that instead of offering new times.

She also mentioned unit 606. I left it out because her card is for Unit 206 and I haven't looked up whether 606 is available.

Her record also says an application was sent on Tuesday, October 13, which is two days from now, so that date looks wrong. She didn't ask about applying, so the email doesn't mention it.

Hi Megan,

The home at 486 32 1/8 Road is no longer available, and I don't have another open home to offer right now.

Hi Nathan,

Thanks for reaching out about 2978 Emerald Circle, it's no longer available right now. I'm not able to send photos through this channel, but I'm happy to help you find something else that fits what you're looking for.

As for fees, the standard security deposit is one month's rent and won't exceed two months' rent, and there's a $40 application fee per applicant. The exact deposit amount is confirmed once your application is reviewed.

A few other homes are open right now: 2841 Morningside Court, a 4 bed, 2 bath at $2,300/mo, 2980 Emerald Circle, a 4 bed, 2.5 bath at $2,300/mo, and 363 Ember Ln, a 3 bed, 2 bath at $2,550/mo. Which of these would you like to see?
Hi Nathan,

2841 Morningside Court, a 4-bed, 2-bath at $2,300/mo
363 Ember Ln, a 3-bed, 2-bath at $2,550/mo

Here's what you'd pay before moving in. The security deposit is one month's rent. The application fee is $40 per applicant. You'd also pay the first month's rent and show proof of renter's insurance before move-in.

I need to correct my last email. The price and size range I gave you wasn't accurate, and that special doesn't have any "select apartments" or "restrictions" conditions on it. The terms are just what I wrote above.

On your pet, what kind of animal is it? The pet fees I mentioned apply to pets. Service and assistance animals are always welcome and don't pay pet fees.

You don't need to pick a time. Your tour is booked for Wednesday, October 7 at 10:30 AM at 1235 Grant Street. Looking forward to meeting you then.

Your review: Opus vs production, prospect first email (30 cards, Oct 28)

Is Opus's first email better than production's?

The judge says yes: Opus wrote the better email on 21 of 30 cards, the same on 7, and production was better on 2. Today's send check would hold 10 of production's emails and 9 of Opus's. 0 Spanish cards in this tier.

  1. Each card is one real renter's first email. Left is production today (Sonnet 5, today's prompt); right is Opus 5.5 on the same prompt with the same inputs.
  2. The shaded box is what the writer was handed: home facts, tour times, special. "Held" means today's send check would stop that email.
  3. Losses first (cards 1 to 2), then ties (cards 3 to 9), then wins (cards 10 to 30). Mark each card better, same or worse for Opus, then press Copy my grades and paste into the chat.

Hi Patrick,

Thanks for reaching out about Camellia Apartments! We've got studios running $950–$1,000/mo (around 386–444 sqft), plus a one-bedroom at $1,200/mo (556 sqft). We're also running one month free on 12-month leases right now, on select apartments — restrictions may apply.

Since you're hoping to move in October 22nd, let's get a tour on the books soon — what day and time works best for you?

Hi Patrick,

Great to hear you're interested! Unit 106 is a studio at $950/mo, 386 sq ft, and with our one month free special on a 12-month lease, that's a great deal. I'd love to get you in to see it before your October 22nd move-in. I have Wednesday, October 28 at 10:00 AM or Thursday, October 29 at 2:00 PM. Which works better for you?

Hi Patrick,

1235 Grant Street has a studio open now. It's a 1-bath with 386 sq ft at $950/mo, and it comes with one month free on a new 12-month lease. What would you like to do next with this one?

Judge: Production better. Both quote the correct studio, rent, size and special, but only Production offers concrete tour slots and sounds like a leasing agent, while its before-move-in slip is minor next to Opus's missing tour push. Opus left out: concrete tour times (Wed Oct 28 10:00 AM / Thu Oct 29 2:00 PM).

2980 Emerald Circle is no longer available, but I can show you a few other homes open now: 2841 Morningside Court (4 bed/2 bath), 2863 Florida Street (3 bed/2 bath), or 363 Ember Ln (3 bed/2 bath).

For today, our office hours end at 5 PM, so evening tours aren't an option — but tomorrow (Saturday) I've got openings between 10:00 and 10:30 AM, or between 12:00 PM and 1:30 PM. Would one of those work, and which home would you like to see?

Hi there,

The home at 2978 Emerald Circle is no longer available. I do have a few other homes open right now: 2841 Morningside Court (4BR/2BA, $2,300/mo), 2863 Florida Street (3BR/2BA, $2,775/mo), and 363 Ember Ln (3BR/2BA, $2,795/mo).

Thanks for letting me know, and for narrowing down to 363 Ember Ln — it's a 3 bedroom, 2 bath home at 1,289 sq ft, $2,550/mo, and it currently comes with the Grand Opening Special: 6 weeks free rent plus water, sewer, and trash included for your first year (you'd cover electricity and internet), running through October 31 or while supplies last.

On the lease length, this home is currently offering longer terms of 14 to 18 months as a promotion, so an 18 month lease works. On the pet, could you clarify what kind of animal it is? Our standard pet policy covers cats and dogs, with a $300 refundable pet deposit and $35/month pet rent per pet, so I want to make sure I give you the right info.

Tomorrow evening isn't available, but I do have Wednesday, October 28 at 5:30 PM or Thursday, October 29 at 5:30 PM open for 363 Ember Ln — would either of those work?

As a quick note, you'd also asked earlier about 2980 Emerald Circle, which is open now as a 4 bedroom if you'd like to see that one too.

Hi Michael,

Thanks for reaching out about Unit 363 Ember Ln at Ember Estates (374 Ember Lane). It's available now, a 3-bedroom, 2-bath with 1,289 sq ft at $2,550/mo. It also has a Grand Opening Special: 6 weeks of free rent, plus water, sewer and trash included for your first year. You'd pay for electricity and internet. The special runs until Oct 31 or while supplies last.

Cats and dogs are welcome. There's a $300 refundable pet deposit and $35 a month in pet rent per pet. What kind of pet do you have?

For lease length, 14 to 18 month leases are being offered right now as a promotion.

I'd be glad to set up a tour for you. What time tomorrow evening works best?

Judge: Production better. Production actually answers the tour question with real checked slots while Opus skips the check and leaves the tour hanging, which outweighs Opus's cleaner tone and single-home focus. Opus left out: that tomorrow evening is not open for a tour; concrete tour times (Wednesday Oct 28 or Thursday Oct 29 at 5:30 PM). Production left out: an explicit statement that 363 Ember Ln is available now.

Thanks for reaching out about the home at 486 32 1/8 Road in Clifton. The home at 486 32 1/8 Road is no longer available. Happy to answer anything else about renting with us.

Judge: Same. The judge leaned to production one way round and called them equal the other way, so it counts as a tie. Both correctly say the home is gone and close with the required warm line; they differ only in a redundant repeated phrase in Opus versus bare terseness in Production.

Hi Danielle,

Thanks for reaching out, and good to know you've got a pet coming along — we're pet-friendly here (there's a $250 one-time pet fee, a $100 refundable pet deposit, and $35/mo pet rent). Since you're thinking 12 months, you'd also be in line for our current move-in special: one month free on new 12-month leases, on select apartments, restrictions may apply. Right now we've got studios and one-bedrooms running $1,000–$1,200/mo, roughly 386–585 sqft.

I'd love to get a tour on the books for you — what's a day and time that works best?

Glad to have you looking at Camellia Apartments! Right now we have a studio open at $950/mo, 386 sq ft, and with a 12-month lease you'd also get one month free. For your pet, there's a $250 one-time fee, a $100 refundable deposit, and $35/mo pet rent.

Hi Danielle,

Camellia Apartments at 1235 Grant Street has a studio open now. It's 1 bed, 1 bath, 386 sq ft, at $950/mo, and on a 12-month lease you'd get our Move-in Special: 1 month free on new 12-month leases.

I need to correct my last email. The price and size range I gave you was wrong, and the open studio above has the right numbers. The special also has no conditions beyond what I just wrote.

You don't need to pick a tour time. You're already booked for Wednesday, October 7 at 10:30 AM at 1235 Grant Street. Looking forward to seeing you then.

Judge: Same. The judge leaned to Opus one way round and called them both wrong the other way, so it counts as a tie. Production is warm and factually sourced but ignores the confirmed tour and offers new slots, while Opus handles the booked tour correctly but misdescribes the studio as a 1-bed and includes a strange self-correction, so neither is fit to send as is. Opus left out: pet fee $250 one-time, $100 refundable pet deposit, $35/mo pet rent (she told us she has a pet). Production left out: Danielle already has a confirmed tour Wednesday, October 7 at 10:30 AM at 1235 Grant Street.

Thanks for your interest in 1235 Grant Street. A studio is available now. It's a 1-bath with 386 sq ft, from $950/mo, and it comes with 1 month free on a 12-month new lease.

Your virtual tour is set for tomorrow, Tuesday, October 13 at 4:00 PM. You don't need to come to the property. Our team will call you at that time on the number we have on file.

Judge: Opus better. Opus answers the availability question with sourced facts, surfaces the special, and correctly confirms the existing virtual tour, while Production gives no facts and wrongly tries to schedule a tour the person already has. Production left out: studio is available now; 386 sq ft, 1-bath, from $950/mo; 1 month free on a 12-month new lease; confirmed virtual tour Tuesday, October 13 at 4:00 PM, team will call them.

Hi Megan,

Our leases are 12 months. Cats and dogs are welcome, with a $300 refundable pet deposit and $35 a month in pet rent per pet.

Judge: Opus better. Both correctly say the home is gone and quote the on-file pet deposit and rent, but Opus also confirms the 12-month lease Megan mentioned and reads more naturally. Production left out: Leases are 12 months (the person specified a 12-month lease).

The 1.5 months free you saw is our Grand Opening Special on the 3-bedrooms at $2,550 and $2,795 a month. You get 6 weeks of free rent, and water, sewer and trash are included for your first year. You'd cover electricity and internet. The special runs until October 31 or until supplies last.

I can show you around Wednesday, October 28 between 9:15 AM and 9:45 AM, or Thursday, October 29 between 9:30 AM and 12:15 PM. Which works better for you?

Judge: Opus better. Opus correctly scopes the 1.5-months-free special to the $2,550/$2,795 listings as the records require, while Production implies the $2,300 home carries it; Production is warmer and tighter but that misstatement is the bigger problem. Production left out: the special applies only to the 3-bedrooms priced at $2,550 or $2,795 a month.

Hi Mary Ann,

Could a 3-bedroom work for you? A leasing agent will meet you at the home. I can show you around Wednesday, October 28 between 9:15 AM and 9:45 AM, or Thursday, October 29 between 9:30 AM and 12:15 PM. Which works better for you?

Production left out: the half-month-free move-in special on the open 3-bedroom listed at $2,495/mo; that she already has a confirmed tour Saturday, October 3 at 11:00 AM at 624 Eisenhauer Street, met by a leasing agent.

I don't have any more photos of the inside or the backyard to send you.

Before you move in, you pay the security deposit and the first month's rent. You also show proof of renter's insurance with at least $100,000 in liability coverage. The standard security deposit is one month's rent, and it's never more than two months' rent. The application fee is $40 per applicant.

Hi Queen,

Thanks for your interest in Unit 206 at Camellia Apartments, it's a studio, 1 bath with 386 sq ft, available now at $1,000/mo. We do offer 6-month leases here at the same rate as our 12-month leases, and right now 12-month new leases also come with a one month free move-in special. On fees: utilities aren't included in rent. Water, sewer, trash and heat run through a third-party biller, Conservice, and for a studio those have typically run around $40 to $50 a month, while electric (through Xcel Energy) and internet are set up directly in your own name. Parking is $80/mo for a surface spot or $95/mo for a garage spot, though on-site parking is full right now, so new residents go on a waitlist, with overflow parking available next door at the nail salon for $100/mo. You're all set for your tour on Tuesday, October 13 at 2:30 PM at 1235 Grant Street, looking forward to showing you around.

Hi Queen,

Thanks for reaching out about Unit 206 at Camellia Apartments. It's available now: a studio, 1-bath with 386 sq ft at $1,000/mo, and we're offering 1 month free on 12-month new leases.

Yes, we offer both 6-month and 12-month leases at the same monthly rent.

Utilities aren't included in rent. Water, sewer, trash and heat are billed monthly through Conservice to your resident portal, and you pay them along with rent. That bill depends on your usage, and studio residents have been paying around $40 to $50 a month. Electric is your own account with Xcel Energy, and internet is your own account too. There's no admin fee.

Parking is $80/mo for a surface spot or $95/mo for the garage. On-site parking is full right now, so new residents join a waitlist. Until a spot opens, the nail salon next door rents spots to Camellia residents for $100/mo, and the leasing office arranges it.

You're all set for your tour on Tuesday, October 13 at 2:30 PM at 1235 Grant Street. Looking forward to showing you around.

Judge: Opus better. Both are accurate and confirm the existing tour, but Opus also answers the community-fee question (no admin fee) and reads more naturally in short paragraphs. Production left out: there is no admin fee (answers the 'other community fees' part of the question); utilities are billed to the resident portal and paid along with rent.

Yes, we offer both 6-month and 12-month leases, and the rent is the same for either one.

Rent doesn't include utilities. Water, sewer, trash and heat are billed through Conservice each month and paid with your rent on the resident portal. Those charges depend on how much you use, and studio residents have paid around $40 to $50 a month. Electric is your own account with Xcel Energy, and internet is your own too.

On-site parking is $80/mo for a surface spot or $95/mo for the garage. It's full right now, so new residents go on the waitlist. Until a spot opens, the nail salon next door rents spaces to Camellia residents for $100/mo, and the leasing office sets that up. There's no admin fee.

Want to come take a look? I can offer Thursday, October 22, 2026 at 5:30 PM, or Friday, October 23, 2026 between 11:30 AM and 12:00 PM, or between 2:00 PM and 5:30 PM. Let me know which works best for you and I'll get it set up.

Hi Emma,

That one's at Ember Estates, which isn't available right now. As I mentioned, Pomona Park Townhomes still has Unit 405 open, a 3-bedroom at $2,495/mo, and we're pet-friendly for your dog and cat. I can show it to you today at 5:30 PM or tomorrow at 11:30 AM. Does either work?

Hi Emma,

Thanks for reaching out about Ember Estates. There's no 1-bedroom open here right now, but the home at 363 Ember Ln is available now. It's a 3-bedroom, 2-bath with 1,289 sq ft at $2,550/mo. It comes with the Grand Opening Special: 6 weeks free rent, plus water, sewer and trash included for your first year. You'd cover electricity and internet, and the special runs until Oct 31 or supplies last.

Your dog and cat are both welcome. The refundable pet deposit is $300 total, and pet rent is $35 per pet per month.

Please disregard the Pomona Park home and the tour times in my last email, since those details weren't correct.

I can show you around Wednesday, October 28 between 10:30 AM and 12:30 PM, or Thursday, October 29 between 2:30 PM and 5:45 PM. Which works better for you?

Judge: Opus better. Opus gives the real open Ember Estates home, rent, size, special, pet fees and the actual tour slots, while Production wrongly says the property is unavailable and offers made-up tour times; Opus's only serious flaw is its unwarranted retraction of the Pomona Park option. Opus left out: Pomona Park Unit 405 remains an open 3-bedroom at $2,495/mo (Email 2 wrongly tells her to disregard it). Production left out: Ember Estates is open with a 3-bedroom, 2-bath (363 Ember Ln, 1,289 sq ft, $2,550/mo); the Grand Opening Special (6 weeks free rent plus water, sewer, trash for the first year, resident pays electricity and internet, through Oct 31 or while supplies last); no 1-bedroom is open at Ember Estates; pet deposit $300 total and pet rent $35 per pet per month; the real tour slots (Wed Oct 28 and Thu Oct 29).

Hi Yoira! Great to hear from you — here's the application link to get started:

https://www.camelliadenver.com/#floor-plans

While you're at it, we have a nice range of options available right now. Studios are running $1,150/mo (386–462 sqft), one-bedrooms at $1,350/mo (540–585 sqft), and a two-bedroom at $1,650/mo (666 sqft). We're also currently offering 1 month free on select apartments, restrictions may apply — so there's a great opportunity to save.

If you'd like to come see the place before or after applying, I have openings as soon as tomorrow morning or afternoon. Would any of those work for you?

Hi Yoira,

Happy to share more about Camellia Apartments! You're all set for your tour on Monday, October 26 at 11:00 AM at 1235 Grant Street, so no need to schedule anything new.

On the lease length, we offer both 6 month and 12 month terms at the same rental rate, so either works here. Just a heads up that our current 1 month free move in special applies to 12 month new leases specifically, so that's worth keeping in mind if the savings matter to you.

Looking forward to showing you around on the 26th. If you have any other questions before then, just let me know.

Hi Yoira,

Unit 402 at Camellia Apartments (1235 Grant Street) is no longer available, but we have a studio open now. It's a 1-bath with 386 sq ft from $950/mo, and there's 1 month free on 12-month new leases.

We offer 6-month and 12-month leases, and the rent is the same for both.

When you're ready to apply, here's the application: https://jpco.appfolio.com/listings

Your tour is already booked for Monday, October 26 at 11:00 AM at 1235 Grant Street. You'll be able to see a studio in person then.

Judge: Opus better. Opus gives the availability, size, rent, special, lease terms, application link and tour confirmation the person needs, while Production only covers lease terms and the tour. Production left out: Unit 402 is no longer available; a studio is open now; the open studio is 1-bath, 386 sq ft, from $950/mo; the application link https://jpco.appfolio.com/listings.

Hi Emma,

That listing isn't one of the homes we currently have open, but Pomona Park Townhomes at 624 Eisenhauer Street still has Unit 405 open now — pet friendly for your dog and cat. Want to go ahead and book a tour? I have Tuesday, October 27 between 5:00 and 5:15 PM, or Wednesday, October 28 in the morning or afternoon, whichever works better for you.
Hi Emma,

Ember Estates doesn't have a 1-bedroom open right now, so that one's not a fit for this budget. The home I mentioned earlier, the 3-bedroom at Pomona Park Townhomes (624 Eisenhauer Street, unit 405, $2,495/mo), is still open if you'd like to see it, pets and all. Want me to get you booked for a tour there?

Inquiry: <user_message> hi, would you be available tomorrow evening for a tour. I am interested in:363 Ember Ln. Pet Description: A pet. Pet Type: Other. Lease Length Months: 18. </user_message>

Production reference (held)claude-sonnet-5 (held)
Thanks for letting me know you're interested in 363 Ember Ln. The good news on lease length: this home is currently offering longer leases of 14 to 18 months as a promotion, so an 18 month term works perfectly here.

On the pet, since it's listed as "Other," I'd love to know exactly what kind of pet it is to make sure it fits our policy. In general we welcome cats and dogs, with a refundable pet deposit of $300 total and pet rent of $35 per pet per month.

For touring, I don't have anything open tomorrow evening for this home, but the earliest opening I have is Wednesday, October 28, anytime between 1:00 PM and 5:45 PM. Would 5:00 PM or 5:30 PM work, or is there another time in that window you'd prefer?
Thanks for narrowing it down to 363 Ember Ln! It's a 3 bed, 2 bath home at 1,289 sq ft for $2,550/mo, and right now it comes with a grand opening special: 6 weeks free rent plus water, sewer, and trash included for your first year (you'd just cover electricity and internet) — that special runs through October 31 or while supplies last. An 18 month lease works too, since we're currently offering longer terms of 14 to 18 months as a promotion. As for your pet, there's a refundable $300 pet deposit and $35/month pet rent, with a two pet limit, and every pet gets registered through OurPetPolicy before move in.

For tomorrow evening, I can do 5:00 PM or 5:45 PM — which works better for you? I'll also need your full name to get the tour booked.

Judge (claude-fable-5-1, both orders): order A picked 1: Email 2 is far more complete on home facts, but inventing a tomorrow-evening tour slot the calendar did not return is a worse error than Email 1's omissions, since Email 1's times are sourced and nothing it says is false. / order B picked 2: Email 1 gives every home fact but invents a tour time its tools did not return, while Email 2 honestly offers the real Oct 28 window yet drops the rent, size and special it was supposed to lead with.

Hi Nathan,

Thanks for reaching out. The home at 2978 Emerald Circle is no longer available. A few other homes we have open right now are 2841 Morningside Court in Grand Junction, 81503, a 4 bedroom, 2 bath at $2,300/mo, 2980 Emerald Circle in Grand Junction, 81504, a 4 bedroom, 2.5 bath also at $2,300/mo, and 363 Ember Ln in Grand Junction, 81501, a 3 bedroom, 2 bath at $2,550/mo.

I don't have extra interior or backyard photos to send over, but once you pick a home I'm happy to get a tour set up so you can see it in person. On fees, the standard security deposit is typically one month's rent and never more than two months, with the exact amount confirmed per home, and there's a $40 application fee per applicant when you're ready to apply.

Which of these homes would you like to see?
Hi Nathan,

The home at 2978 Emerald Circle is no longer available. A few options that are open right now: 2841 Morningside Court in Grand Junction, a 4 bed/2 bath at $2,300/mo; 2980 Emerald Circle in Grand Junction, a 4 bed/2.5 bath at $2,300/mo; and 363 Ember Ln in Grand Junction, a 3 bed/2 bath at $2,550/mo.

On fees: the standard security deposit is one month's rent and won't exceed two months' rent, and there's a $40 application fee per applicant. As for more interior and backyard photos, that's one the property team can go over with you at your tour. Want me to get one on the books?

Hi Nathan,

Thanks for reaching out. The home at 2978 Emerald Circle is no longer available. A few other homes we have open right now are 2841 Morningside Court in Grand Junction, 81503, a 4 bedroom, 2 bath at $2,300/mo, 2980 Emerald Circle in Grand Junction, 81504, a 4 bedroom, 2.5 bath also at $2,300/mo, and 363 Ember Ln in Grand Junction, 81501, a 3 bedroom, 2 bath at $2,550/mo.

I don't have extra interior or backyard photos to send over, but once you pick a home I'm happy to get a tour set up so you can see it in person. On fees, the standard security deposit is typically one month's rent and never more than two months, with the exact amount confirmed per home, and there's a $40 application fee per applicant when you're ready to apply.

Inquiry: <user_message> Hello, I'm interested in a studio apartment (unit 206/606) at Camellia Apartments and am looking to move in around October 14. Do you offer 6-month lease options? I'd also like to know what additional monthly fees are charged besides the base rent, such as utilities, parking, trash, or other community fees. Thank you!. Pet Description: no pets. Pet Type: None. Lease Length Months: 1. </user_message>

Production reference (held)claude-opus-5-5 (held)
Hi Queen,

Yes, Camellia offers both 6-month and 12-month lease terms at the same rental rate, so a 6-month lease works just fine for Unit 206 (the studio, 386 sq ft, $1,000/mo, available now).

Beyond rent, water, sewer, trash and heat are billed monthly through our third-party biller, Conservice, based on usage (studio residents have generally seen it run about $40 to $50 a month, though it varies). Electric is your own account with Xcel Energy and internet is set up on your own as well. Parking is optional, $80/mo for a surface spot or $95/mo for a garage spot (on-site parking is full right now, so new residents join a waitlist, and there's overflow parking next door for $100/mo arranged through our office), and there's no admin fee here. Since you mentioned no pets, there's nothing else to add on that front.

Looking forward to seeing you for your tour this Tuesday, October 13 at 2:30 PM!
I wrote Queen's first reply, which is ready to send above. One thing doesn't add up. The prompt says today is October 27, but the system context says October 11. I went with October 11, so I treated her October 13 tour as still ahead and confirmed it instead of offering the October 28 and 29 slots. If today is really the 27th, that tour has already passed and the reply needs new tour times.

What the email covers:
- **Unit 206:** a studio with 1 bath, 386 sq ft, $1,000/mo, available now. I also mentioned the 1 month free special on 12-month new leases.
- **6-month lease:** yes, at the same rent as a 12-month lease.
- **1-month lease:** her inquiry form listed a 1-month lease length, and nothing on file covers that. I sent the question to the property team and told her I'd check and get back to her.
- **Fees:**
- Water, sewer, trash and heat come through Conservice. They're usage-based, and studio residents have paid around $40 to $50 a month.
- Electric (Xcel Energy) and internet are her own accounts.
- There's no admin fee.
- Parking is $80 surface or $95 garage. It's full with a waitlist, and the nail salon next door rents spots for $100 a month.

**Unit 606** didn't show up in the available studios, so I left it out. I didn't say it's unavailable, because there's no result for it either way.

The application on file shows as sent on October 13, which is after October 11. She didn't ask about applying, so I didn't mention it.

I saved her as a lead: studio, unit 206, moving in around October 14, no pets.

Production reference (held)claude-opus-5-5
Thanks for letting me know you're interested in 363 Ember Ln. The good news on lease length: this home is currently offering longer leases of 14 to 18 months as a promotion, so an 18 month term works perfectly here.

On the pet, since it's listed as "Other," I'd love to know exactly what kind of pet it is to make sure it fits our policy. In general we welcome cats and dogs, with a refundable pet deposit of $300 total and pet rent of $35 per pet per month.

For touring, I don't have anything open tomorrow evening for this home, but the earliest opening I have is Wednesday, October 28, anytime between 1:00 PM and 5:45 PM. Would 5:00 PM or 5:30 PM work, or is there another time in that window you'd prefer?

Hi Carmen,

The home at 624 Eisenhauer Street, Unit 300 is no longer available. Pomona Park Townhomes doesn't have a studio open right now, but there is a 3 bedroom townhome open, with rent starting from $2,395 a month. The current listing is $2,495 a month and comes with a Move-In Special: get 1 half month of rent free.

I can show you the home Tuesday, October 27 between 5:00 PM and 5:15 PM, or Wednesday, October 28 between 9:00 AM and 9:45 AM. Which works better for you?
I sent Carmen her first email. It says Unit 300 is no longer available and no studio is open at Pomona Park Townhomes right now.

- **What's open:** I told her about the 3-bedroom, 2.5-bath townhomes: 1,450 to 1,528 sq ft, at $2,395 to $2,495 a month. These are well above the $900 budget on her card. Per the rules, I gave the rent as it is and didn't compare it to her budget.
- **Special:** The $2,495 home has a move-in special of half a month's rent free, so I put that next to its rent. The listing's full terms say the 12-month lease has to be signed by October 31, 2026. I only used the short version from the listing's special line, so that deadline isn't in the email.
- **Laundry:** Her card asked for on-site laundry. The property has no amenities on file, so I used the $2,495 home's own listing, which includes an in-unit washer and dryer.
- **Tour times:** I offered today at 5:15 PM or Wednesday, October 28, anytime between 1:15 PM and 5:45 PM. Nothing is booked yet.

**The date doesn't match.** The message from the property says it's Sunday, October 4. The rest of the setup and the availability check both say today is Tuesday, October 27. I went with the 27th, but if the 4th is right, "today at 5:15 PM" is the wrong day. That would also leave her only four days to sign if she wants the special.

I saved her as a lead with her email address, not as a phone number, because no phone number is on file. Her saved details are a studio, move-in 11/01/2026, a $900 budget, no pets and on-site laundry. Nothing went to the property team, since everything she asked was answered.

2026-11-03 · Staff desk turn (a teammate writing to Clara): Opus 5.5 against Sonnet 5.5

What changed: Candidate: move the staff leasing desk turn (Clara answering someone on the customer's own team, by text or email) from claude-sonnet-5-5 to claude-opus-5-5. Nothing else changed between the arms.. Tier: exploratory (Two full passes per arm on the same app code (d3f34befc2), arms run side by side. Served model checked on every one of 810 calls (requested = served).) Status: complete.

Set: Staff-reaction regression harness (43 fixtures), pre-v1, ad hoc 2026-11-03. 43 fixtures · 18 fixtures that reach the staff desk turn · 2 skipped (call channel, voice minutes rationed). No bench surface exists for the staff turn, so this is the 43-fixture harness on the fede/staff-reaction-regression-harness branch: real producers send the notice, the staff reaction enters through the real email or text door, local DynamoDB, wire cut at the socket. 18 of 41 runnable fixtures reach the staff desk turn; the rest stop at the reader, run another path, or run no model.

Judge and Fede

claude-fable-5-1, vs Sonnet 5.5 on the same fixture, same pass (Blind pair, both orders; a side wins only when both orders agree. Two fixtures (syn-09, syn-15) ran the same model in both arms and the judge still picked a side 3 of 4 times, so a single-run win is noise.): All 41 runnable fixtures, both runs: Sonnet 15 / tie 54 / Opus 11. Desk fixtures only: Sonnet 13 / tie 16 / Opus 7.. Per arm in the table above.

no review set written for this run

Controls

all red 3 of 3 caught. Judge: planted filler ('Thanks, noted!') against the real reply on 3 fixtures, both orders: the real reply won 3 of 3. Served model checked on all 810 calls. The harness's own controls (replied-only grader, wrong expectation, fixture drift, name leak) are in results/before-2026-11-03.md on the harness branch.

Cost and speed

Ran on the Claude subscription. Not measured separately; both arms ran side by side, about 14 minutes a pass.

Caveats

  • One check-level regression appeared (syn-19, Opus asks 'who's she?'). It is missing information: the quoted notice is stripped and the turn opens a new thread, so no model can see who 'she' is. Sonnet stayed silent on the same input; both fail the action.
  • seed-03 (Opus says there is no text number on file): the prompt never tells Clara her text line, so Opus gave the honest answer and Sonnet guessed. Not a model loss.
  • Most failures (19 of 41) are code: notices with no reply key, the quote stripped, the hidden office building chosen as scope, its notices module off, '(by text)' on email notes, the notice-thread turn with no desk. No model swap moves them.
  • Small set: 18 fixtures reach the desk turn. The harness grades outcomes, not every word.

2026-11-02 · Fede's Wrong cards are now a frozen check; prospect replies have an upgrade surface

What changed: No change to Clara. The bench now replays every Fede card it can rebuild on every arm and fails an arm while a Wrong card reproduces (clara-benchmark #65); bench upgrade gains the prospect_reply surface on a new frozen set v2 of 53 recorded turns (clara-benchmark #66). Two production-only runs prove both.. Tier: smoke (Both runs are the smoke tier (30 items each). Production against itself only: these runs set the floor, they do not test a candidate.) Status: complete.

Set: Clara Bench frozen sets v1 (tenant text) and v2 (prospect reply turn), v1 + v2. 30 tenant text (smoke) · 30 prospect reply turn (smoke) · 18 Fede's rated cards (17 Wrong, 1 Fine). v2 is new: 53 recorded turns where a renter wrote back (Western Slope 42, Situs Group 11, Oct 24 to 30), each replayed on the prompt production recorded for it. It judges model swaps only, never prompt changes.

Judge and Fede

claude-fable-5-1, vs production reference run, same window, same items (Blind pair, both orders; a side wins only when both orders agree. Fede cards: a code check per card plus a 3-vote Fable card judge where words alone cannot tell.): Tenant run 2 9 W / 12 T / 9 L; prospect reply run 2 6 W / 12 T / 12 L. Per arm in the table above.

no review set written for these floor runs

Controls

all red 36 of 36 caught. Fede cards: every stored Wrong output (plus card 1's two synthetic twins and the Fine card) fed back through the checks, 18 of 18 as planted. Each run's own controls 18 of 18 (code checks, served model, write blocker, judge).

Cost and speed

Ran on the Claude subscription.

Caveats

  • Not runnable as Fede cards: 28 (door cannot rebuild that first email), 31 and 41 (prospect replies replay their recorded prompt, which predates the fix), 43 (the sender is not an active tenant), 45 (pressed in Slack only, no rating row).
  • Tenant texts are off in production since Oct 27, so the 6 reproduced misses reach no renter; they are the bar a tenant prompt must clear.
  • The prospect reply surface judges a model swap only; every turn replays its own recorded prompt, so a prompt change cannot be measured on it.
  • Not judged by any bench surface: the quiet-lead follow-up (Haiku), the text after the first email (Haiku condense), the held-message redraft, and the arrival-instructions translation.

  • Request shape: every claude-sonnet-5 call sent effort high, max_tokens 16384, thinking adaptive summarized, tool_choice auto, temperature none, the same shape the pre-staged swap branch sends, so the numbers transfer.
  • Production's own reply varies run to run, so every line holds the arm to production against itself (run 2), not to zero.
  • Inputs frozen per card: the door's first answer for each card's context and each tool call was kept for the window, so the reference, run 2 and every candidate saw the same home facts and tour slots. Those values are as of the run day, not the card's day (the door lists home_facts_as_of_today and tour_state_as_of_today); card-day values need an as-of read in the app (issue #47).
  • Spanish slice: 0 Spanish first emails are in this tier (the 4 in the set have no lead ids the door can rebuild), so the exit bar's Spanish line is not measured here.
  • Invented facts is a pattern check (an amount, phone, email or link not in the prompt or tool results); on first emails most flags are rents read from listing pages, so read it as an upper bound.
  • Stability (the same writer three times in one hour) and the Willows end-to-end run are later rungs; this is the replay rung only.

Judge and Fede

claude-fable-5-1, vs production reference run, same window, same items (Blind pair, both orders; a side wins only when both orders agree, otherwise tie. First emails: the judge also lists the facts each email drops that the other gives (counted only when both orders list one).): 10 / 27 / 14. Per arm in the table above.

Controls

all red 23 of 23 caught. Code checks 18 of 18 as planted (red and clean twins); served-model proof refuses sonnet 5.5 when sonnet 5 was asked; write blocker refused 4 planted writes and sends; judge 9 of 9 (identical pair: no side picked, no drop; real reply beats filler; facts cut: drop listed, cut email never better; thank-you opener taken out: never production better; deflection: pet question put off, pet policy on file; deflection: a question the records do not answer).

Cost and speed

About $45.58 at list. Ran on the Claude subscription. List price of the writer tokens (cache reads at 0.1x input, cache writes at the one-hour 2x); the judge is not counted. Rates as Benchmark B published them (Sonnet 5 $2 / $10, Opus 5.5 $4 / $20 per million); no rate on file for other models. Per item: $0.894. Latency: Production reference 39 s per turn; Production run 2 (noise floor) 35 s per turn; Candidate claude-opus-5-5 23 s per turn. p50 of one whole turn (tool loop plus the door), 4 workers.

Caveats

  • harness: pass. 51 of 51 ran, 0 errors; served claude-opus-5-5 (as asked); prompt same as the reference on 51 of 51.
  • controls: pass. all planted defects caught.
  • holds: pass. held 13 vs reference 14 (allowed up to 17; production run 2 held 14).
  • never_do: FAIL. no_em_dash 0 new (run 2: 1); no_team_told 1 new (run 2: 0); offers_tour_times 0 new (run 2: 1).
  • facts: pass. drops a fact production gave on 4 (run 2: 11, allowed 13).
  • quality: pass. production better on 1, this arm better on 30, tie 20 (run 2: production better 10, allowed 12).
  • graded: pass. production better on 0 of 9 graded cards (run 2: 3).
  • spanish: not measured. not measured: 0 Spanish items run in this tier.
  • Request shape: every claude-opus-5-5 call sent effort high, max_tokens 16384, thinking adaptive summarized, tool_choice auto, temperature none, the same shape the pre-staged swap branch sends, so the numbers transfer.
  • Production's own reply varies run to run, so every line holds the arm to production against itself (run 2), not to zero.
  • Inputs frozen per card: the door's first answer for each card's context and each tool call was kept for the window, so the reference, run 2 and every candidate saw the same home facts and tour slots. Those values are as of the run day, not the card's day (the door lists home_facts_as_of_today and tour_state_as_of_today); card-day values need an as-of read in the app (issue #47).
  • Spanish slice: 0 Spanish first emails are in this tier (the 4 in the set have no lead ids the door can rebuild), so the exit bar's Spanish line is not measured here.
  • Invented facts is a pattern check (an amount, phone, email or link not in the prompt or tool results); on first emails most flags are rents read from listing pages, so read it as an upper bound.
  • Stability (the same writer three times in one hour) and the Willows end-to-end run are later rungs; this is the replay rung only.

Caveats

  • harness: pass. 51 of 51 ran, 0 errors; served claude-opus-5-5 (as asked); prompt same as the reference on 51 of 51.
  • 'Prompt same as the reference' compares the door's assembled input (same build for every arm); the cut is applied inside the writer after that, which is why this arm's input tokens are lower (cache writes 3.78M vs 4.93M for uncut Opus).
  • controls: pass. all planted defects caught.

  • Request shape: every claude-opus-5-5-cut call sent effort high, max_tokens 16384, thinking adaptive summarized, tool_choice auto, temperature none, the same shape the pre-staged swap branch sends, so the numbers transfer.
  • Production's own reply varies run to run, so every line holds the arm to production against itself (run 2), not to zero.
  • Inputs frozen per card: the door's first answer for each card's context and each tool call was kept for the window, so the reference, run 2 and every candidate saw the same home facts and tour slots. Those values are as of the run day, not the card's day (the door lists home_facts_as_of_today and tour_state_as_of_today); card-day values need an as-of read in the app (issue #47).
  • Spanish slice: 0 Spanish first emails are in this tier (the 4 in the set have no lead ids the door can rebuild), so the exit bar's Spanish line is not measured here.
  • Invented facts is a pattern check (an amount, phone, email or link not in the prompt or tool results); on first emails most flags are rents read from listing pages, so read it as an upper bound.
  • Stability (the same writer three times in one hour) and the Willows end-to-end run are later rungs; this is the replay rung only.
  • Fede's 7 rated cards (the real bar): on today's inputs no arm repeats his misses; on the cards' original frozen inputs the cut prompt does not beat uncut Opus (both repeat the special and 'leasing agent will meet you' misses). Judge wins here are not a PASS on Fede's bar.

  • Request shape: every claude-sonnet-5 call sent effort high, max_tokens 16384, thinking adaptive summarized, tool_choice auto, temperature none, the same shape the pre-staged swap branch sends, so the numbers transfer.
  • Production's own reply varies run to run, so every line holds the arm to production against itself (run 2), not to zero.
  • Inputs frozen per card: the door's first answer for each card's context and each tool call was kept for the window, so the reference, run 2 and every candidate saw the same home facts and tour slots. Those values are as of the run day, not the card's day (the door lists home_facts_as_of_today and tour_state_as_of_today); card-day values need an as-of read in the app (issue #47).
  • Spanish slice: 0 Spanish first emails are in this tier (the 4 in the set have no lead ids the door can rebuild), so the exit bar's Spanish line is not measured here.
  • Invented facts is a pattern check (an amount, phone, email or link not in the prompt or tool results); on first emails most flags are rents read from listing pages, so read it as an upper bound.
  • Stability (the same writer three times in one hour) and the Willows end-to-end run are later rungs; this is the replay rung only.

  • What was benched: production as deployed at commit b9314a41, which includes main 8c0a2b86 and the five cleanup PRs (#23000 no counts, #23002 tour times, #22931 and #22925 topic 7, #22852 no budget verdict, #23013 internal text held, #22778 prompt examples store). The door served prompt b9314a41d743 to every arm on all 30 items; the prompt pin never moved.
  • Bench changes since the pre-cleanup run: the judge no longer rewards or marks down a thank-you opener (clara-benchmark #49, issue #46; a new judge control proves it); every arm and the judge read the same frozen door inputs per card (#50, part of issue #47); this window runs under its own label so the Oct 28 rows stay as published (#51).
  • The 2 new never-do fails, read by hand: invented_facts on rs-2026-10-24-n25 is a false flag (the $950 rent Opus quoted is in its own get_available_units result as "rent":950; the pattern check looks for "$950"), and the judge preferred Opus's email there. no_team_told on bench-a:2593008a is real ("I'll check with the team" on the 1-month term with no ask opened), and production's send checks held that email, so it would not have been sent. The bar counts both as written.
  • harness: pass. 30 of 30 ran, 0 errors; served claude-opus-5-5 (as asked); prompt same as the reference on 30 of 30.
  • controls: pass. all planted defects caught.
  • holds: pass. held 9 vs reference 9 (allowed up to 12; production run 2 held 11).
  • never_do: FAIL. no_invented_tour_time 0 new (run 2: 1); invented_facts 1 new (run 2: 1); no_team_told 1 new (run 2: 0).
  • facts: pass. drops a fact production gave on 7 (run 2: 9, allowed 11).
  • quality: pass. production better on 9, this arm better on 11, tie 10 (run 2: production better 9, allowed 11).
  • graded: pass. production better on 4 of 9 graded cards (run 2: 5).
  • spanish: not measured. not measured: 0 Spanish items run in this tier.
  • Request shape: every claude-opus-5-5 call sent effort high, max_tokens 16384, thinking adaptive summarized, tool_choice auto, temperature none, the same shape the pre-staged swap branch sends, so the numbers transfer.
  • Production's own reply varies run to run, so every line holds the arm to production against itself (run 2), not to zero.
  • Inputs frozen per card: the door's first answer for each card's context and each tool call was kept for the window, so the reference, run 2 and every candidate saw the same home facts and tour slots. Those values are as of the run day, not the card's day (the door lists home_facts_as_of_today and tour_state_as_of_today); card-day values need an as-of read in the app (issue #47).
  • Spanish slice: not measured, 0 Spanish first emails in this tier. The set's 4 Spanish first emails (all Situs, full tier) carry only the card id. Read-only lookups found 1 of them (n40) has a lead record the door can rebuild; the other 3 have no lead record, and 2 of those have no inquiry text. No other Spanish first email exists in our records today. Blocker and options: clara-benchmark issue #52.
  • Invented facts is a pattern check (an amount, phone, email or link not in the prompt or tool results); on first emails most flags are rents read from listing pages, so read it as an upper bound.
  • Stability (the same writer three times in one hour) and the Willows end-to-end run are later rungs; this is the replay rung only.
  • re-scored with #53 fixed: invented_facts 0 (clara-benchmark #54, no new model calls, same frozen prompt and stored tool results). Every invented_facts flag in this window was a rent the arm's own unit lookup returned as a JSON number: Opus 1 to 0 ($950 on rs-2026-10-24-n25), the reference 3 to 0, production run 2 3 to 0. Never-do would still FAIL on no_team_told alone (1 new vs run 2 0); the published numbers above are left as run.

2026-10-28 · Model upgrade bench: claude-opus-5-5 on today's prompt after the open-home line fixes (#23112, #23161) (prospect first email, smoke)

What changed: The writer model only: claude-sonnet-5 to claude-opus-5-5, on production's prompt as deployed, which now carries #23112 and #23161 (the Open now line gives the open home's bath, size and rent).

Caveats

  • Question: now that the Open now line hands the writer the open home's bath, size and rent (#23112, #23161), does Opus 5.5 on today's prompt beat production's first email?
  • Answer: yes, clearly, on the smoke tier. Opus wins 21 of 30 cards against production and loses 2, with no never-do fails and fewer held emails.
  • Before (previous row, same 30 cards, before #23112 and #23161) to after: judge vs production 12 W / 6 T / 12 L to 21 W / 7 T / 2 L; held 8 vs 10 to 9 vs 10; never-do 0 to 0; drops a fact production gave 11 to 4; Fede's graded cards where production is better 3 of 9 to 0 of 9; Spanish 0 items both times.
  • The 7 cards the open-home fix targeted: none lose now. 5 are Opus wins (a91c01f3, rs n26, rs n30, rs n28, 0004d4d1) and 2 are ties (788e78b9, 9f53122e).
  • Other watched cards: 45fe6594 loss to win; 1ceb6095 loss to tie; dea7389b loss to tie; fee9a96c still a loss (production offered tour times the returning-prospect rule did not ask for; Fede ruled Oct 28 that first emails always offer times, not yet in the prompt); 51020788 still a loss (no tour slot line in Opus's inputs, production checked the calendar).
  • Watch item: Opus wrote a line correcting an earlier email on 2 returning-prospect cards (rs-2026-10-24-n25 'I need to correct my last email', bench-a:37e9db7f 'Please disregard the Pomona Park home and the tour times in my last email'). Production wrote 0. No code check catches this yet.
  • Noise floor: production against itself scored 9 W / 14 T / 7 L this window.
  • harness: pass. 30 of 30 ran, 0 errors; served claude-opus-5-5 (as asked); prompt same as the reference on 30 of 30.
  • controls: pass. all planted defects caught.
  • holds: pass. held 9 vs reference 10 (allowed up to 13; production run 2 held 11).
  • never_do: pass. no_em_dash 0 new (run 2: 1).
  • facts: pass. drops a fact production gave on 4 (run 2: 10, allowed 12).
  • quality: pass. production better on 2, this arm better on 21, tie 7 (run 2: production better 7, allowed 9).

Caveats

  • Question: after the first-email rule fixes (#23123: the email is the email itself, lease terms on file answer a term ask, photo asks answered, deposit cap in the same sentence), does Opus 5.5 on today's prompt now clear the bar against production's first email?
  • Answer: yes, on the smoke tier. Opus passes every bar line for the first time: no never-do fails, fewer held emails than production, and as many wins as losses against production.
  • Before (previous row, same 30 cards, before #23123) to after: verdict FAIL to PASS; judge vs production 11 W / 10 T / 9 L to 12 W / 6 T / 12 L; held 9 vs 9 to 8 vs 10; never-do 2 (1 real told-the-team, 1 grader bug) to 0; Fede's graded cards where production is better 4 of 9 to 3 of 9; Spanish 0 items both times.
  • The two cards #23123 targeted both flipped from a production win to an Opus win: bench-a:2593008a (before: wrote a note about the email instead of the email, and told the person it would check with the team on a lease term) and bench-a:8940bc4f (before: skipped the photos ask and dropped the deposit cap).
  • The four Open now cards still lose, as expected (#23112, which puts bath, size and rent on that line, is not merged): bench-a:788e78b9, bench-a:a91c01f3, bench-a:9f53122e, rs-2026-10-24-n26. Three more cards lost the same way this run (rs-2026-10-24-n30, rs-2026-10-24-n28, bench-a:0004d4d1): production looked the open home up and gave its size and rent, Opus did not. So 7 of the 12 losses are that one gap.
  • The other 5 losses: one card with no tour times in its inputs (bench-a:51020788, same as before), one where production offered tour times the rules did not ask for (bench-a:fee9a96c, same as before), two where Opus repeats the address twice when saying the home is gone (bench-a:45fe6594, bench-a:1ceb6095; the second tied last run), and one wording call (bench-a:dea7389b).
  • Noise floor: production against itself scored 5 W / 12 T / 13 L this window, so a 12 / 6 / 12 split for Opus is better than production's own rerun. Opus also took fewer held emails (8 vs 10) and answered in 22 s per turn vs 51 s, at about twice the list cost.
  • harness: pass. 30 of 30 ran, 0 errors; served claude-opus-5-5 (as asked); prompt same as the reference on 30 of 30.
  • controls: pass. all planted defects caught.

  • Production's own reply varies run to run, so every line holds the arm to production against itself (run 2), not to zero.

2026-10-28 · Goal block bench: claude-opus-5-5 with a short goal placed first in the first-email prompt (prospect first email, smoke)

claude-fable-5-1, vs production reference run, same window, same items (Blind pair, both orders; a side wins only when both orders agree, otherwise tie. First emails: the judge also lists the facts each email drops that the other gives (counted only when both orders list one).): 18 / 9 / 3. Per arm in the table above.

Fede graded 0 of 8 review-set examples from this run. Judge calibration: agrees on 0 of 0 graded (–); 8 rows have a judge call.

Controls

all red 19 of 19 caught. Code checks 13 of 13 as planted (red and clean twins); served-model proof refuses sonnet 5.5 when sonnet 5 was asked; write blocker refused 4 planted writes and sends; judge 7 of 7 (identical pair: no side picked, no drop; real reply beats filler; facts cut: drop listed, cut email never better; thank-you opener taken out: never production better).

Cost and speed

About $25.58 at list. Ran on the Claude subscription. List price of the writer tokens (cache reads at 0.1x input, cache writes at the one-hour 2x); the judge is not counted. Rates as Benchmark B published them (Sonnet 5 $2 / $10, Opus 5.5 $4 / $20 per million); no rate on file for other models. Per item: $0.853. Latency: Production reference 37 s per turn; Production run 2 (noise floor) 39 s per turn; Candidate claude-opus-5-5-goal 21 s per turn. p50 of one whole turn (tool loop plus the door), 4 workers.

Caveats

  • Question: does opening the first-email prompt with a short goal (book a tour with real times, answer from the inputs, never invent, never a second home or counts, never correct an earlier email) make Opus 5.5's first email better, with nothing else changed?
  • Answer: too close to call. With the goal, Opus wins 7 and loses 5 of 30 head to head against itself without the goal, holds fewer emails (7 vs 9) and stopped correcting earlier emails, but sent one empty email, which the stopping rule counts as a new never-do.
  • Before (no-goal Opus, same window, same frozen inputs) to after (with goal): vs production 21 W / 7 T / 2 L to 18 W / 9 T / 3 L; head to head 7 W / 18 T / 5 L for the goal; held 9 to 7; never-do 0 to 1 (empty email on rs-2026-10-24-n36: the writer saved the prospect and ended without writing); 'correct my last email' lines 2 to 0; drops a fact production gave 4 to 5; emails with a tour time 21 to 20; Fede's graded cards where production is better 0 to 1; Spanish 0 items.
  • Where the goal won: 1ceb6095, 51020788, 8940bc4f, 37e9db7f, 69a41391, rs n25, rs n34 (two of these are the 'disregard my last email' cards). Where it lost: 0004d4d1, 2af82304 and 04799e27 left out the special or lease and deposit details, 62e4aff9 dropped one closing line, rs n36 sent nothing.
  • Stopping rule (written before the run): adopt if the goal arm beats or ties the no-goal arm with no more holds and no new never-do; delete if it loses by 3 or more or holds rise; otherwise run the full tier. It won 7 to 5 with fewer holds but one new never-do, so: full tier once, then decide. A one-sample empty email may be noise; the full tier settles it.
  • Cost column: the goal block sits in front of the cached span, so the cached token count is not comparable to the no-goal arm.
  • The goal block was injected by a local runner option (--prompt-prefix-file, clara-benchmark worktree clara-bench-wt-post23161, not committed).
  • harness: pass. 30 of 30 ran, 0 errors; served claude-opus-5-5 (as asked); prompt same as the reference on 30 of 30.
  • controls: pass. all planted defects caught.
  • holds: pass. held 7 vs reference 10 (allowed up to 13; production run 2 held 11).
  • never_do: FAIL. no_em_dash 0 new (run 2: 1); no_empty_reply 1 new (run 2: 0).
  • facts: pass. drops a fact production gave on 5 (run 2: 10, allowed 12).
  • quality: pass. production better on 3, this arm better on 18, tie 9 (run 2: production better 7, allowed 9).
  • graded: pass. production better on 1 of 9 graded cards (run 2: 3).
  • spanish: not measured. not measured: 0 Spanish items run in this tier.
  • Production's own reply varies run to run, so every line holds the arm to production against itself (run 2), not to zero.
  • Inputs frozen per card: the door's first answer for each card's context and each tool call was kept for the window, so the reference, run 2 and every candidate saw the same home facts and tour slots. Those values are as of the run day, not the card's day (the door lists home_facts_as_of_today and tour_state_as_of_today); card-day values need an as-of read in the app (issue #47).
  • Spanish slice: 0 Spanish first emails are in this tier (the 4 in the set have no lead ids the door can rebuild), so the exit bar's Spanish line is not measured here.
  • Invented facts is a pattern check (an amount, phone, email or link not in the prompt or tool results); on first emails most flags are rents read from listing pages, so read it as an upper bound.
  • Stability (the same writer three times in one hour) and the Willows end-to-end run are later rungs; this is the replay rung only.

Judge and Fede

claude-fable-5-1, vs production reference run, same window, same items (Blind pair, both orders; a side wins only when both orders agree, otherwise tie. First emails: the judge also lists the facts each email drops that the other gives (counted only when both orders list one).): 8 / 5 / 17. Per arm in the table above.

Fede graded 0 of 8 review-set examples from this run. Judge calibration: agrees on 0 of 0 graded (–); 8 rows have a judge call.

Controls

all red 17 of 17 caught. Code checks 11 of 11 as planted (red and clean twins); served-model proof refuses sonnet 5.5 when sonnet 5 was asked; write blocker refused 4 planted writes and sends; judge 6 of 6 (identical pair: no side picked, no drop; real reply beats filler; facts cut: drop listed, cut email never better).

Cost and speed

About $22.2 at list. Ran on the Claude subscription. List price of the writer tokens (cache reads at 0.1x input, cache writes at the one-hour 2x); the judge is not counted. Rates as Benchmark B published them (Sonnet 5 $2 / $10, Opus 5.5 $4 / $20 per million); no rate on file for other models. Per item: $0.74. Latency: Production reference 52 s per turn; Production run 2 (noise floor) 46 s per turn; Candidate claude-opus-5-5 29 s per turn. p50 of one whole turn (tool loop plus the door), 4 workers.

Caveats

  • harness: pass. 30 of 30 ran, 0 errors; served claude-opus-5-5 (as asked); prompt same as the reference on 30 of 30.
  • controls: pass. all planted defects caught.
  • holds: pass. held 10 vs reference 11 (allowed up to 14; production run 2 held 9).
  • never_do: FAIL. no_em_dash 0 new (run 2: 1); invented_facts 3 new (run 2: 0); no_team_told 0 new (run 2: 1); no_empty_reply 1 new (run 2: 0).
  • facts: FAIL. drops a fact production gave on 10 (run 2: 7, allowed 9).
  • quality: FAIL. production better on 17, this arm better on 8, tie 5 (run 2: production better 7, allowed 9).
  • graded: FAIL. production better on 5 of 9 graded cards (run 2: 3).
  • spanish: not measured. not measured: 0 Spanish items run in this tier.
  • Request shape: every claude-opus-5-5 call sent effort high, max_tokens 16384, thinking adaptive summarized, tool_choice auto, temperature none, the same shape the pre-staged swap branch sends, so the numbers transfer.
  • Production's own reply varies run to run, so every line holds the arm to production against itself (run 2), not to zero.
  • Spanish slice: 0 Spanish first emails are in this tier (the 4 in the set have no lead ids the door can rebuild), so the exit bar's Spanish line is not measured here.
  • Invented facts is a pattern check (an amount, phone, email or link not in the prompt or tool results); on first emails most flags are rents read from listing pages, so read it as an upper bound.
  • Stability (the same writer three times in one hour) and the Willows end-to-end run are later rungs; this is the replay rung only.

2026-10-27 · Step 1: today's leasing first-email prompt split into four pieces, on production's own model

What changed: Today's production first-email prompt cut into four pieces (rules, voice, facts, task) under four bare headers, with no word added, removed or reworded, run on production's exact model and compared with production run three times (the noise floor).. Tier: full (Every runnable first email (51 of 53; two graded examples from Fede's review set, n27 and n33, cannot be rebuilt by the door). No Spanish first emails exist in the set.) Status: complete.

Set: Clara Bench frozen set v1, v1. 51 prospect first email. The same 51 runnable first emails as slice H. Each request is assembled read-only by the service door from production's live state, then sent on the subscription.

Judge and Fede

claude-fable-5-1, vs production run A (Pair judge, both orders; 'same email' only when both orders say so, 'better' only when both orders agree, otherwise tie. Differences named by type (special, tour times, home facts, other homes, answer, hand-off, tour state, voice, dash). Calendar-minute shifts in offered times are not a difference.): Split vs A: 13 W / 27 T / 11 L; noise B vs A: 12 / 24 / 15; noise C vs A: 12 / 25 / 14. Per arm in the table above.

No review set for step 1; step 2 carries the review page.

Controls

all red 15 of 15 caught. Split proof: rebuilding the prompt from the pieces gives production's text byte for byte on 51 of 51; the only added text is the four headers and their joins (123 characters on every item). Judge controls 5 of 5: an identical pair judged the same; a dropped special, a changed rent, an added em dash and removed tour times each judged different with run A better. Code check controls red on every run folder (9 of 9 planted).

Cost and speed

Ran on the Claude subscription, no metered key. Not compared: arms ran against a live door, so timings mix door and model time.

Caveats

  • Model: claude-sonnet-5, read from PropFlow main (REASON_FIRST_DRAFTING_MODEL in the model tiers file, commit 7e165fc302); the door reported the same production model on all 51. No Opus arm in step 1.
  • Production deployed during run A: 18 of its rows came from deploy 322c99a810. Those 18 were re-run on be3fb76491 and re-judged. Run C came from a2f1cbfe0c. The prompt text is identical across these deploys; only the live rent in the listing data differs.
  • Four emails differ from production in a way production does not show with itself (production matched itself in at least 2 of 3 noise pairs, the split in 0 of 3): 9e8290a0 (the split did not look up open units, so it left out the price range and size production gave all three times); 8369a26b (wording only, it drops 'available now'; repeats show production varies here too); 629f8d14 (the split looked up units, quoted the listing special terms and named the home by its street address, which production did not do in 4 of 4); 9f53122e (the split used an em dash).
  • Two borderline counts lean the split's way but sit inside the floor: check availability 3 vs 6 / 8 / 6, and home named by street address where the card says not to 14 of 27 vs 8 / 11 / 12.
  • A first attempt that kept whole paragraphs together (home facts beside the rules) was worse (em dash 9, update prospect 15, held 30) and was dropped before this row; the row is the first cut.
  • Fede's graded first-email examples: 7 in the review set ledger (n25, n26, n27, n29, n30, n33, n34); 5 are runnable here and are in the 51. Step 2 uses them as the floor.

2026-10-26 · Slice H: full context versus restrictive (Opus, decomposed prompt)

What changed: Writer setting on the v1 runner: production writer, Opus 5.5 on the decomposed prompt (restrictive), and the same plus door 2 facts block from frozen records (full context), no draft checks applied to the candidates.; tenant texts get the same full arm from a frozen tenant record (clara-benchmark #29). Tier: full (First email full (51), tenant other text full (150), tenant repair text smoke (20, every item the door can rebuild). Tenant full context (added Oct 26 evening): the door already gives the tenant writer the tenant, unit, lease dates, open work orders at the text, property knowledge and the thread, so the tenant full arm is the same facts frozen and re-rendered as one block with an id on every line, plus the lease terms (rent, due day, late fee, autopay) and a "Context missing" line built from the door's own omitted list (balance always, office actions before the turn, open matter, renewal, work order status on the day). All three tenant arms were rerun together that evening on the same items so they compare.) Status: complete.

Set: Clara Bench frozen set v1, v1. 51 prospect first email · 20 tenant repair text · 150 tenant other text. Same items as the Oct 25 baseline rows (first email full 51, tenant repair smoke 20, tenant other full 150). Frozen first-email facts: sets/v1/prospect-first-email.context.json, 69 of 73 items, all 51 runnable covered, recorded Oct 23 by Bench A. Frozen tenant facts (added Oct 26 evening): sets/v1/tenant-repair-text.context.json (20 of 20) and tenant-other-text.context.json (150 of 150), each record with a content hash.

Judge and Fede

No judge: Candidates were not judged; tenant-other judge controls failed on Oct 25, so a judge column would not count.

No review set for this run.

Controls

all red 12 of 12 caught. Byte-identical proof of the production writer: one door read per item, the request built by origin/main and by the new runner compared byte for byte: first email 51 of 51, tenant repair 20 of 20, tenant other 150 of 150 identical; planted controls (one changed byte, changed model, changed tool list) 0 of 6 identical on each side. Code check controls ran red per run (team-told English and Spanish, em dash, invented amount, Spanish in English, each with a clean twin). Broken-promise check: planted booked-no-booking and told-team-no-ask RED, clean twins GREEN (unit test). Code check controls red on 9 of 9 run folders. Tenant rerun: code check controls red on 6 of 6 run folders (9 of 9 each); tenant facts swap planted controls (no lease named missing, block missing or doubled throws, prospect record refused) in clara-benchmark #29; swap applied to all 170 real rebuilds, 0 failed.

Cost and speed

Ran on the Claude subscription (Keychain bearer, no metered key). Token counts are not totalled per run. Not compared: arms ran one after another against a live door, so timings mix door and model time.

Caveats

  • Tenant answer, in plain words: does the full facts block help Opus on tenant texts? No on the headline. With every fact laid out it speaks more often where the office had already answered: noise 44 of 99 (44%) restrictive → 53 of 99 (54%) full, still far below production's 84 of 99 (85%). Helpful moves little (54% → 56%, production 62%). Repair texts (20): noise 6 → 7 of 10 (production 10 of 10). Spanish (27): noise 10 → 11 of 13 (production 13 of 13); every candidate reply was in Spanish.
  • Production row is today's production, not the Oct 25 numbers: the production prompt moved since Oct 25 (sha f230e51b then, the sha in the row now) and the writer is not deterministic, so the Oct 25 counts cannot be re-drawn. Byte-identical is proven at the request: the default writer sends exactly the request the Oct 25 runner sent (221 of 221 items).
  • First email frozen facts are from Oct 23. Their tour slots (Oct 24 to 25) are past, so the full arm is told tour slots are missing and reads this turn's calendar. Availability changed since freeze on 5 of 51 items (home name on 0); the door's send checks compare against live facts, so up to 5 full-arm holds may be staleness.
  • "Held by send checks" for the candidates is production's deterministic first-email checks run on their draft at the door, reported only: no redraft and no draft checks applied inside the candidate turn.
  • Broken promises is a pattern check: a tour stated as booked with no booking tool call, or a "told the team" sentence with no ask opened (declare_deferred_asks, notify_leasing_team, escalate_to_human, forward_to_property_manager).
  • Invented facts is a pattern check (an amount, phone, email or link not in what the writer was given); on first emails it over-flags rents read from listing pages. Read it as an upper bound.
  • Candidates were not judged against the office reply (the judge runs on the production arm only, and its tenant-other controls failed on Oct 25).
  • Broken promises read 18 hits before a fix: every one was "You're all set for your tour" on a lead whose guest card already had a confirmed tour (production's TOUR STATE, 14 of 14 items checked by a read-only door read). The check now honours a tour on record (clara-benchmark #28) and the count is 0 in every arm.
  • Production's own "no tour times" first-email finding fires on leads that already have a confirmed tour (6 of its 8 production fires, 7 of 11 in the full arm); that is a production check behaviour, reported here and not changed.
  • Full context on first email: 1 empty reply and 3 "told the team" replies (bench-a:37e9db7f; bench-a:290eb6b7, bench-a:2593008a, bench-a:0365fde5) where production had none; 3 of its 4 invented-fact flags and 3 of its 16 holds are on items whose availability changed since the freeze.
  • Tour-time gates (calendar read, forced retries) are not measurable on this run: the prompt already carries this turn's slots and any confirmed tour, and the bench does not store the prompt to check each named time.
  • Zero writes executed: the door blocks every write in full mode; nothing was sent.
  • Tenant numbers in this row are the Oct 26 evening rerun (all three arms together, same 170 items); they replace the first pass. First pass for reference, tenant other: production noise 83 of 99, restrictive 39 of 99 (prompt sha eb0c9083c8fa). Production moved twice since: repair arms all ran on eff6366e6ca3; tenant other production ran 87 items on eff6366e6ca3 and 63 on 9e4cb603efde, restrictive and full all on 9e4cb603efde.
  • Tenant frozen facts come from the door's read-only rebuild cut at the text (work orders open at the text, thread up to the text) plus a get_lease_terms read in door full mode (340 activity-log writes blocked by the door). The balance is never frozen: today's balance would say what happened after the text. The office reply is the truth label and is never in the record.
  • The frozen thread says "our side" for every earlier outbound message: the door's history does not say whether Clara or a staff member sent it. A work order closed since the text shows its status today (the door names this as missing on 64 of 170 items).
  • Full vs restrictive on the 99 tenant-other texts the office answered: full replied and restrictive stayed quiet on 11, the reverse on 2.
  • Production reproduces its first-pass numbers closely: tenant other noise 84 of 99 (first pass 83), helpful 76 of 122 (62%) (70 of 122); repair noise 10 of 10 both times.
  • Spanish items: the code check reads each reply's language (Spanish replies to Spanish texts); only the production arm is judged against the office reply, in Spanish for Spanish items, and its tenant-other judge controls failed again (2 of 5 caught), so no judge column counts.

2026-10-25 · Baseline v1 (production, Oct 25)

What changed: No change: production as deployed today (writer claude-sonnet-5, filing classifier claude-sonnet-4-6) measured on the frozen v1 set, the baseline every refactor and model is compared to.. Tier: full (Mixed by surface. Tenant other text ran full (146 of 150; 4 door errors) and smoke (30). Prospect first email ran full (51 of the 73 that the door can rebuild) and smoke (30). Tenant repair text ran smoke only (20, every item the door can rebuild in full mode; the other 241 are frozen in light mode and were not run). Spanish is read off the rows of the other surfaces (23 full, 11 smoke), not run on its own. Prospect reply turn, renewals and voice are empty in v1.) Status: complete.

Set: Clara Bench frozen set v1, v1. 73 prospect first email · 0 prospect reply turn · 261 tenant repair text · 150 tenant other text · 421 Spanish slice · 0 renewals · 0 voice. Frozen Oct 25 in the clara-benchmark repo (sets/v1, LOCK.json with sha256 and item counts, drift test with mutation controls). Git holds ids, lineage, labels and content hashes; masked text lives only in the local store. Stay-quiet truth comes from the AppFolio mirror: an office reply in the thread within 48 h means stay quiet; anything else is unknown and stays out of the noise rate.

Judge and Fede

Fable 5.1, vs the office's reply from the AppFolio mirror (blind pairwise, both orders, a win counts only when both orders agree; rubric notes the office can act in person): Tenant repair smoke 6 / 1 / 4 (Clara better / same / office better, n=11), controls 5 of 6. Tenant other text not valid: controls failed.. Per arm in the table above.

No review set was made for the baseline; Fede's Oct 24 verdicts belong to earlier runs.

Controls

not all red 23 of 32 caught. Code checks 9 of 9 per run (team-told reply in English and Spanish RED, real answer GREEN, em dash, invented amount, Spanish answered in English; each with a clean twin). Write blocker 4 of 4 planted sends and writes refused before item one, every run. Judge (office reply vs planted filler, must prefer the office): tenant repair 5 of 6; tenant other text 5 of 13, so its judge numbers do not count. Drift test: one-byte change, removed item, missing surface and planted content all go RED.

Cost and speed

Ran on the Claude subscription. Token counts were not recorded per call, so no list price. Latency: Tenant other text, full 26.3 s median per item; Tenant repair text, smoke 15.8 s median per item; Prospect first email, full 43.3 s median per item. Whole item: door context, filing classifier, production writer turn with read tools, checks and judge.

Caveats

  • Noise rate is the primary score per Fede, Oct 25 ("should we reply at all"): an item where the office answered in the thread within 48 h should get silence; replying there is noise. Items with no office reply within 48 h are unknown and left out. The helpful rate is second: a "I don't have that, I've let the team know" reply counts as a failure.
  • Live production noise is 0 today by configuration: the tenant reply switch is off at Western Slope and Situs. The service door skips that switch, so this row measures what the writer would do if it were on.
  • Ran full: tenant other text (146 of 150, 4 door errors: 3 network, 1 missing thread) and prospect first email (51). Ran smoke only: tenant repair text (20, the only items the door can rebuild; 215 predate the mirror and 26 could not be assembled, frozen in light mode, not run). Prospect first email: 22 of the 73 frozen items cannot be rebuilt by the door. Spanish numbers are the Spanish rows of the runs above.
  • Judge: tenant other text judge numbers are not valid. Its controls (office reply vs planted filler) passed 5 of 13, because the mirror's next office message often answers a different text in the same thread (for example a pest control note paired with a smoking complaint). The noise rate does not use the judge, so it stands. Tenant repair judge passed 5 of 6.
  • The judge rubric gained a note that the office can act in person, after the first controls failed; the smoke rows were re-judged with it. Re-judged rows use the door context fetched before the filing step.
  • Invented facts is a pattern check (a dollar amount, phone, email or link not in the context or tool results). On prospect emails most flags are rents read from listing pages that the check does not see, so it over-flags; read it as an upper bound.
  • Zero writes executed: the door refused 190 write attempts and blocked 240 effects; 0 notices. #western-slope had 0 messages before the run and 3 after, all live Agent Smith cards for a new Zillow lead who is not in the set, posted before the prospect run started.
  • Prospect first email has no judge (code checks and send-check holds only). Phone is out of scope for v1 (Fede, Oct 25).

2026-10-24 · Benchmark D3: office-conversation rule replaces the 24 h teammate gate

What changed: The code gate that silenced any thread a teammate wrote on in 24 h is replaced by one line stating the last office-teammate message; the model decides whether the tenant's text continues that exchange (silent) or is a separate question it can answer. Two outcomes only. Opus reply check blocks staff-run, questions-only-on-urgent and bare-acknowledgement drafts.. Tier: exploratory (Ad hoc redo of D2 with the gate replaced, before the frozen Clara Bench v1 set exists.) Status: complete.

Set: Tenant texts: inbox copy, Situs history, Spanish F set, extra Spanish Situs, pre-v1, ad hoc 2026-10-24. 383 recent inbox texts · 300 Situs history sample · 365 Spanish texts (F set) · 145 extra Spanish Situs texts. Same 1193 rows / 1092 distinct texts as D2. Per-set rows count rows. D3 calls the model on every distinct text (D2 skipped 653 via the 24 h gate).

Judge and Fede

Fable 5.1, vs the paired staff reply (only an office message that actually answers the text) (blind, order swapped, paired staff replies only, new rubric (chiming in on an office-run thread loses, a hand-off is never a win)): Opus recent 4 / 2 / 0 (n=6), new rubric; Sonnet recent 2 / 1 / 3 (n=6). Per arm in the table above.

Fede graded 24 of 24 review-set examples from this run. Judge calibration: agrees on 4 of 5 graded (80%); 18 rows have a judge call. Disagree: #9. Void or re-grade: #1, #2, #3, #4. Note, no call: #5, #6, #7, #10, #11, #12, #13, #14, #15, #20, #21, #22, #23.

Controls

all red 17 of 17 caught. 9 decision controls (office-run threads silent, plain repair and knowledge-only address questions reply, mass-text answer reply, outage silent), 6 reply-check controls and 2 hold-check controls all behaved as expected on both models. First pass scored 20 of 23 on Fede's examples; each of the three fixes carries a planted control. Judge remains soft on filler (staff beat filler 3 of 6 on F's Spanish set).

Cost and speed

Decision pass at list: Opus $39.52 for 1092 calls, Sonnet $18.72 for 1091 calls, about 2.6x D2 ($15.25 and $6.78 for 439 calls each) because D3 calls the model on every distinct text. Opus hold and reply checks add $2.67 (Sonnet arm $2.64). Ran on the subscription. Per item: Opus median $0.0333, Sonnet median $0.0157 per decision call. Latency: Opus 5.5 3.4 s median, 6.2 s p90; Sonnet 5.5 2.0 s median, 2.5 s p90. Decision call only.

Caveats

  • Supersedes 2026-10-23-bench-d2
  • Opus matches Fede on 22 of 23 graded examples (D2 20, Sonnet 20). The only miss is #4: Fede graded an older draft ("did you leave the keys?"), the current draft answers office hours from the knowledge base, so it needs his re-grade, not a rule change.
  • The graded examples were also used to write the rules, so the agreement number is in-sample. The planted controls and per-set numbers are the out-of-sample evidence.
  • Removing the 24 h gate: of 697 rows it silenced in D2, Opus now replies on 11 and Sonnet on 7; Fable calls none of them staff-run. Routine texts answered went up on recent (10 → 12 of 50) and Spanish (12 → 17 of 75) and down on Situs history (10 → 7 of 44).
  • Sonnet sends 2 staff-run replies by Fable's measure (one tenant's key return, 34 days after a promise; counted in two sets) and stays silent on #5 and #17, both graded as wanted replies. One Sonnet text failed output validation twice and counts as silent.
  • Staff-run is a model judgement (Fable), not ground truth; Fede has graded only 24 tenant examples. Judged pairs are small (n=2 to 8 per arm); the judge is soft on filler, so a Clara win is weaker evidence than a loss.
  • On an outage the Situs records hold no emergency line, so the honest outcome is silence; adding those facts to the knowledge base is the real fix.

Judge and Fede

Fable 5.1, vs the office's real work order and actions (one blind Fable call per episode for labels and one for the judge, plus code checks): Judge overall mean 4.56 Opus, 4.38 Sonnet. Per arm in the table above.

No Fede verdicts recorded for these episodes yet; 28 episodes are on the review page.

Controls

not all red All 11 planted real writes refused (6 harness + 5 store writes). Contradicting tenant, planted emergency, and permission already on the open work order passed on both arms. Clean episode: Opus filed before asking permission to enter and added it as a note one turn later (fail); Sonnet passed. The judge caught the planted wrong unit and the made-up $185 fee.

Cost and speed

All calls on the subscription; the report gives tokens, not dollars (Opus writer 334 calls, Sonnet 389). Latency: Opus 5.5 5.2 s median per Clara turn, 10.5 s p90; Sonnet 5.5 2.3 s median, 6.1 s p90. Writer call per Clara turn.

Caveats

  • Supersedes Benchmark G (2026-10-23-bench-g), which ran under the old three outcomes.
  • Before and after on Opus: filed when the office filed 11 to 8 of 42; filed when the office filed nothing 21 to 10 of 219; episodes with a text 70 to 34 of 261; invented facts 13 to 1; texts quoting an internal id 10 to 0.
  • Split by who ran the thread: where staff ran it, Clara filed 1 of 19 (correct to stay out); where nobody ran it, 7 of 23.
  • Open problem: where nobody runs the thread she still misses 16 of 23 filings, mostly by staying silent on a text addressed to a staff member by name or on a repair already in the portal.
  • 250 of 261 replays are one turn: Clara texted nothing in 178 episodes.
  • The staff-run label is one Fable read per episode and marked 143 of 261 threads staff-run, which is generous; it pulls the filing rate down by design.
  • "Office filed nothing" can be wrong: a phone call, a later work order, or one under another name is invisible; Situs history is matched by tenant name.
  • 42 episodes are co-tenant duplicates of another episode's text (19 groups), kept one per tenant page.
  • One Fable judge and one Fable labeller per episode; spot checks show some label noise.
  • Not the production tenant prompt: D2 two-outcome rules plus repair rules.

  • Ran under the old three outcomes (reply / post to the team / silent): 23 of the 31 Opus misses were "posted to the team instead", an outcome Fede removed on Oct 23 night. Being redone under two outcomes as G2.
  • 232 of 261 replays are one turn: Clara texted nothing in 164 episodes, and 13 stopped when the next real message no longer fit.
  • "Office filed nothing" can be wrong: a phone call, a later work order, or one under another name is invisible; Situs history is matched by tenant name.
  • Stub results leak: the filing returns STUB-WO-1, which Clara sometimes quotes to the tenant; appliance lookup and key pickup always return empty.
  • One Fable judge and one Fable labeller per episode; spot checks show some label noise.
  • Not the production tenant prompt: Benchmark D rules plus two repair lines.

Judge and Fede

Fable 5.1, vs the next office message (written and answered in Spanish, pairwise, both orders): Opus 26 / 1 / 2, Sonnet 22 / 1 / 4. Per arm in the table above.

Fede graded 0 of 4 review-set examples from this run. These rows have no judge call (code checks only), so no calibration number.

Controls

not all red All 6 planted Spanish defects caught by both the code check and the Spanish judge, and the clean native reply passed. Not all red: on the pairwise filler control the judge preferred the filler 2 of 6, both on texts where the next office message was not an answer.

Cost and speed

About $25.16 at list. $25.16 at list on the subscription; reused Benchmark D and A outputs not counted again. Per item: see Cost per text column. Latency: Opus 5.5, full context 6.5 s median; Sonnet 5.5 medium, full context 3.3 s median.

Caveats

  • Judge W/T/L and the staff-answered counts are under re-pairing (Fede, Oct 23: a mass text is never a reply); superseded when the complete-context redo (bench-d2) lands.
  • Prospects: 3 of 4 Opus emails and 1 of 4 Sonnet emails carry English tour times ("el Friday, October 23 at 3:00 PM"); 4 cards is too few for anything beyond that defect.
  • All of it is Situs; Western Slope has 0 Spanish texts and 0 Spanish cards.
  • No native speaker has checked the naturalness scores yet.
  • Grades rest on 40 (Opus) and 38 (Sonnet) replies; one reply moves a rate by 2 to 3 points.

Judge and Fede

Fable 5.1, vs the paired staff reply (only an office message that actually answers the text; mass texts, notices and earlier messages never count) (blind, order swapped, paired staff replies only; also scored with the new rubric (chiming in on an office-run thread loses, a hand-off is never a win)): Opus recent 6 / 0 / 0 (n=6), new rubric 5 / 0 / 1. Per arm in the table above.

Fede graded 24 of 24 review-set examples from this run. Judge calibration: agrees on 4 of 5 graded (80%); 18 rows have a judge call. Disagree: #9. Void or re-grade: #1, #2, #3, #4. Note, no call: #5, #6, #7, #10, #11, #12, #13, #14, #15, #20, #21, #22, #23.

Controls

not all red 4 of 4 caught. All four planted texts decided as expected under the 9-rule prompt on both models (three office-run threads silent, plain repair report reply); the 7-rule prompt failed three of them, so the rules matter. Earlier controls (write refused, send suppressed, teammate rule, pairing, usted default, word-for-word judge, hold gate) all passed. Not all red: the judge is still soft on filler (new rubric: D's staff won 9 of 10 controls, F's Spanish staff won 3 of 6).

Cost and speed

Decision calls at list: Opus $15.25 for 439 calls, Sonnet $6.78 for 439 calls (was $24.72 and $10.51 for 947 calls each). Texts the teammate rule catches cost nothing; the hold check adds one Opus call per draft reply. Ran on the subscription. Per item: Opus median $0.0323, Sonnet median $0.0143 per decision call (complete context). Latency: Opus 5.5 5.2 s median, 8.8 s p90; Sonnet 5.5 2.3 s median, 4.0 s p90. Decision call only.

Caveats

  • Supersedes the tenant rows of 2026-10-23-bench-d and 2026-10-23-bench-f: every tenant number there used windowed context, three outcomes, and "the next office message" as the staff reply. 31 of the 114 published judged pairs were void (judged against a non-answer).
  • Fewer replies is the intended direction under the two-outcome rule: replies only where Clara can help, none on a staff-run thread, nothing invented. The open problem is routine texts that warrant a reply: Opus 18 to 10 of 50 on recent texts (21 of the 50 now go silent by the teammate rule). The prompt is too timid.
  • Two defects still present: Clara jumps in where the tenant addressed a staff member directly, and asks triage questions where staff had something concrete (an emergency line, a dispatched tech).
  • Judged pairs are small after pairing (n=2 to 7 per arm); a single flip moves the picture. The judge is still soft on filler, so a Clara win is weaker evidence than a loss.
  • The unanswered count (Opus: 694 silent but reply warranted, 349 with no answer within 7 days) cannot see calls, emails or in-person answers, so it overstates what nobody answered.
  • Western Slope has no tenant pages in our dump (no flags, notes or event log) and its text history starts Sep 30 2026; 24 of 209 recent Situs texts had no matching tenant page; Situs texts between Sep 1 and Sep 30 are missing from both sources.
  • Lease sizing is a model read (2 likely, 42 maybe, 306 no of 350); no lease documents were read.

Judge and Fede

Fable 5.1, vs the staff reply that went out (blind, order swapped, only where a staff reply exists): Opus full context 24 / 5 / 2 across both sets. Per arm in the table above.

Fede graded 24 of 24 review-set examples from this run. Judge calibration: agrees on 4 of 5 graded (80%); 18 rows have a judge call. Disagree: #9. Void or re-grade: #1, #2, #3, #4. Note, no call: #5, #6, #7, #10, #11, #12, #13, #14, #15, #20, #21, #22, #23.

Controls

not all red Fact, promise, teammate and leak checks and the hold gate caught every planted defect and passed the clean ones; 5 of 5 write verbs and the planted send refused. Not all red: on the planted vague-filler control the final judge still preferred the filler 1 of 5 (3 staff, 1 tie), and the first judge prompt was replaced after it preferred filler 4 of 5.

Cost and speed

About $100 at list. About $100 at list for the whole run (incl. triage of 1,994 texts and three judge setups), on the subscription. Per item: see $ / text column. Median seconds per text in the Median sec column.

Caveats

  • Judge W/T/L and the staff-answered counts are under re-pairing (Fede, Oct 23: a mass text is never a reply); superseded when the complete-context redo (bench-d2) lands.
  • About 31 compared replies per arm; a few flips swing the judge result.
  • "The next office message" is the staff reply, and sometimes it is not an answer; "nobody replied" may mean the office called back.
  • The first two judge setups were discarded (one truncated staff replies at 160 characters, one counted anything staff knew beyond our records as invented).
  • Knowledge base is today's for every text; older texts may be judged against facts that did not exist yet.
  • Too quiet: the same Opus model in the triage pass called 50 recent texts routine, the decision run replied to 18 of them.

Cost and speed

889k input tokens per model; output 168k (Opus) and 210k (Sonnet) over 712 messages. Code deciders cost nothing. Per item: Opus 5.5 about $0.01 per message (plan page section 8). Latency: Thin prompt, Sonnet 5.5 4.2 s median; Thin prompt, Opus 5.5 3.6 s median. Code deciders run in under 5 seconds for all 712.

Caveats

  • * The one model leak is the same Situs message for both: a "Yes" from a number whose only dated record at the time was a leasing inquiry; the tenant label was applied later.
  • Emails (17) go through a different code path that was not replayed and score as silent.
  • Our copy of the inbox only reaches back to Sep 30; Clara's own line is not in the run.
  • First pass: 33 Sonnet and 2 Opus answers were empty or cut off at 600 output tokens; all re-ran clean at 2,000.

Judge and Fede

No judge: No judge: the run measures tokens, cache and cost, not quality.

No review-set examples come from this run.

Controls

No controls: No graded checks in this run, so no planted-defect controls; every replay ran under the write blocker with outbound suppressed.

Cost and speed

Prices Sonnet 5 $2 in / $10 out, Opus 5.5 $4 in / $20 out, cache read $0.20, one-hour cache write $4 / $8. Per item: see $ / turn columns. Writer p50 per turn type; two of today's Sonnet 5 replays ran 142 s and 184 s (long thinking runs).

Caveats

  • Later-turn 'proposed' rows are estimates from the block plan; no thin prompt exists yet for those turn types.
  • 7 of 10 Opus replays of today's prompt started warm, so their latency is flattered; cost is from token counts and unaffected.
  • Part of the latency gap is effort (today high with a 16k cap, thin medium with 4k), not prompt size alone.

2026-10-23 · Benchmark A: today's first-reply prompt vs the thin prompt

What changed: Thin first-reply prompt vs today's prompt, on Opus 5.5 and Sonnet 5.5 medium. Tier: exploratory (Ad hoc run on tonight's corpus, before the frozen Clara Bench v1 set exists; not a smoke or full tier.) Status: complete.

Set: Whole guest-card corpus + production first emails, pre-v1, ad hoc 2026-10-23. 966 past cards · 110 production first emails. 966 past cards (721 Western Slope, 232 Situs, 13 Camellia, Aug 2021 to Oct 22, 2026) and 110 production first emails (Sep 20 to Oct 23). Tables score 72 production first emails and 179 past cards per side.

Judge and Fede

No judge: The optional panel judge was not run; every grade is a code check.

Fede graded 7 of 12 review-set examples from this run. These rows have no judge call (code checks only), so no calibration number. Note, no call: #25, #26.

Controls

all red 47 of 47 caught. 47 grader checks, each with a planted mistake and a clean twin, all pass; 5 grader false alarms found by reading the worst emails were fixed and given controls. The write blocker refused one planted write and one planted send before any card.

Cost and speed

About $63 at list. About $63 at list for the whole run, on the subscription. Prices Sonnet 5 $2/$10, Opus 5.5 $4/$20; the repo price file says Sonnet 5 is $3/$15, which would make today 1.4x higher. Per item: see $ / card column. Median writer seconds per card in the Sec / card column; thin is 3 to 7x faster.

Caveats

  • 65 to 75% of today's drafts were held by the fact-trace and tour-time checks, which read facts today's writer never saw; those holds are excluded from the scores.
  • Today's past-card drafts ran in a sandbox seat: they read Fairhaven's company knowledge and 35 offered Fairhaven homes. The 72 production first emails are the fairest comparison.
  • Availability, tour-time correctness and invented facts are not graded on cards older than 7 days.
  • Thin writers ran on Oct 23 with the live calendar, so their tour times are this week's, not the inquiry week's.
  • All 3 Spanish cards got English tour times on the thin prompt; today's side had almost no Spanish cards.

Human labels: one record, every rater (Fede's go, Oct 25)

The question: when a person rates a Clara reply (a button on a shadow card in Slack, a thumb in the app, a grade Fede gives in chat), where does it go and how does the bench use it? The answer: one record, the verdict the app already stores for thumbs, now with a source and a rater; the bench reads it as the truth for the noise score and as the review set. Fede's labels outrank every other rater.

                                                               Clara Bench reads both: GradeVerdict = truth, MachineGrade = candidate flags

Cerebrus, the machine grader on that arrow: what it is, what it has caught, and and the decision on it (Fede, Oct 30: D, fold) are on the Cerebrus section. Its 362 old flags are discarded (Fede, Oct 30); whether new flags arrive here as cards with these same four buttons is his open call on that section.

Button on the cardMeansStored as

Keyed by conversation id + message id + rater + source; a second press by the same person replaces the first. Pieces: PropFlow route and record fields (PR 1), the Slack socket relay and card update (PR 2, harness repo), buttons on the card (shadow runner, session 006), the bench read (PR 3). Status is on the asks ledger until the merged master page carries it.

Card v2, proposed Oct 25 evening (Fede: "more context, colors, remove fluff"; designed from Slack's Block Kit guide and review-card patterns in n8n, Linear and Intercom). One card, seven blocks: who and where (tenant, property, unit) · channel, time and a PropFlow link · what the tenant wrote · what Clara would say · what the office did and how long it took · one line of work order and reason · the four rating buttons plus Add a note. Colors: a left stripe by situation (gray Clara stays quiet, blue Clara would reply, amber a person already answered, purple Clara would file a work order); green and red only on the Fine and Wrong buttons. After a press the buttons become "Rated Fine by Kat · time"; if recording fails the card says so and asks for another press. Runner needs five new fields (office reply text and sender, tenant name, property and unit, channel, work order summary). Open for Fede: stripe via legacy attachment vs colored emoji in the header (recommend stripe); note via a small form vs a thread reply (recommend form). Sample posted in #updates-fede Oct 25 6:09 PM MT.

Status, Oct 25 evening MT: the app route and record fields are live in production (PR 22411 merged), the Slack relay runs on the mini (agent-smith 1472 merged, signing secret restored from SSM the same evening; it had never been on the mini). A relay-signed no-op payload got HTTP 200 from production, nothing written. Buttons are live on the shadow cards; Fede's first presses landed Oct 26 and are read back below by the bench (clara-benchmark PR 26, npm run bench -- labels).

What the ratings say (read Oct 26, 3:51 PM MT)

The question: do Fede's presses on the shadow cards match the AI judge? The answer: none of the 8 cards Fede rated has a judge verdict yet (shadow cards are not judged), so the agreement rate is not measurable until a bench run judges those texts.
