Day100Bench
Day100Bench is a data room from an invented add-on acquisition, an answer key, and a grading script. It asks the questions an integration lead gets in week one: what will hurt us, what we are paying for twice, which dates cannot slip, and what order the work should happen in. Run it on any model or vendor tool. We have not published model results yet.
Sample grading of one finding, the Pacific Timber consent issue. Citing section 14.2 with the right deadline counts. Citing page 4 counts. A wrong deadline gets half credit. Citing section 14.1 gets no credit. Citing section 19.4, which does not exist, costs two points. Below it, a timeline of the dates that cannot slip.

How an answer is graded
This is the first issue in the answer key and the clause behind it. Below it are six ways a model might report it, and what the grader does with each. We ran each one through the grading script to confirm the result.
Pacific Timber Cooperative ASO Agreement, section 14.2
Pacific Timber is the target's largest client, at 14.2% of revenue. Its contract requires written consent to a change of control. If consent is not given within 30 days of close, the client can leave on 90 days' notice without penalty.
Change of Control. Any Change of Control of Administrator shall require the prior written consent of Client. If Administrator undergoes a Change of Control without such consent, Administrator shall notify Client in writing within five (5) business days, and if Client's written consent is not obtained within thirty (30) days following the Change of Control, Client may terminate this Agreement upon ninety (90) days' written notice without penalty and without regard to §3.1. "Change of Control" means any transaction or series of transactions by which a person or group other than Northwind Insurance Group, Inc. acquires control of, or all or substantially all of the assets of, the business unit performing the Services.
What the test asks
Standalone runs receive one prompt per task. Operator runs record each agent configuration and use only sources released for that task. Each section is graded by rule against the answer key.
35 points
The documents contain 22 issues. 9 are material, such as a change-of-control clause on the largest client and a stop-loss database kept on one analyst's desktop. The model has to name the type of each issue, cite where it sits, and for material issues give the deadline and what happens if nobody acts. A finding counts only when both the type and the citation match the answer key. A material finding with the wrong deadline or consequence gets half credit. One client contract looks like a consent problem but is not, and flagging it costs points.
15 points
Both companies' software schedules are in the room. The model has to find the products that appear on both, give the target's annual cost for each one, and add them up. Some entries look like matches but are not, and counting them costs points.
10 points
There are 8 dates to track, from the client consent window to the day the seller stops hosting the claims system. Each needs the right date and a citation. One of them depends on an event the documents do not date, and the model has to say that instead of guessing.
25 points
The model gets 30 candidate actions. 14 are required and 3 are wrong for this deal. It has to choose, schedule them by day, respect notice periods and minimum gaps, meet the deadlines, and mark which actions cannot be undone. For example, a termination notice cannot be undone, but building a data map can.
15 points
In a second prompt the model gets an amended transition services agreement and an issue list. We run it two ways. In one, the list is the correct one from the answer key. In the other, the list is the model's own first answer, so an issue it missed stays missed. For each of 15 issues it has to say whether the issue is resolved, changed, worse, or unchanged, and cite the clause that decides it. The new draft also creates problems of its own.
Reported separately
A run is flagged if it misses any of these: the Pacific Timber consent issue, with its deadline and consequence, the client consent date, the ClaimsLink non-renewal notice date, the claims platform cutover date. The flag does not change the score. It is shown in its own column next to the total.
The deal
Meridian Benefits Administrators, a PE-backed third-party administrator, buys Cascade Health Plan Services, a business unit carved out of an insurance group. The seller keeps running the claims platform, email, payroll, and EDI under a transition services agreement. The deal closes on November 30, 2026. Every company, person, contract, and number is invented, so nothing in the room is confidential.

The two companies both pay for 7 products, and the target spends $209,284 a year on them. Terms in the data room stop $172,032 of that from being cancelled on its own.
Nothing in the documents blocks the other $37,252. The pack has no notice periods, migration costs, or data on whether the buyer can absorb the target's users, so that number is not a savings figure either. The test scores the overlap today. It does not yet score which spend can be removed, or when.

Who built this
We sell software for post-close integration work, so we have a stake in how AI tools look on this test. These are the safeguards.
The data room, the answer key, the prompts, and the grading code. Run any model or vendor tool on it and you will get the same number we would.
Get startedRun your tool on this data room. The grading script scores it the same way it scores every model.
Get startedIf you have run an integration like this and think an item in the key is wrong, create an account and tell us which one and why. Accepted changes get a new key version and every model is rerun.
