Transaction-Coordination Copilot

Compute deadlines from the executed instrument with the governing clause quoted, escalate them as they approach and after they lapse, and hold the acts with legal effect for the licensee of record.

What this agent does

Carries the calendar, never the legal act

In
01

Track the executed contract, its amendments and the form version in force, each with the document it came from.

02

Track document receipt against the contract checklist, and report what is outstanding rather than clearing it.

Reason
03

Compute candidate deadlines from the instrument's own text, with the governing clause quoted beside each date.

04

Compute against the form's business-day convention, holiday calendar and cut-off time, never a house default.

05

Compute the schedule again on any amendment, since a moved date changes what sits downstream of it.

Decide
06

Escalate a date ahead of expiry and again on lapse, because a passed date cannot be un-passed afterwards.

07

Escalate inbound mail carrying wire or payment content to a person, with the instructions left out of the summary.

Out
08

Retain the instrument, the computed dates, the escalations and the approvals to the state retention schedule.

09

Execute write actions only inside the approval boundaries agreed during implementation.

Product statement

The agent computes and escalates; the licensee of record decides, and in attorney states the closing attorney decides.

Example workflow

One contract, execution to close

4Controls appliedVersion checks, day-convention checks, wire-content screening and confidence threshold
No human action required

Stages 1 to 4 run unaided, and nothing is filed or sent at any of them — the agent is computing dates, and the licensee's lane opens at the confidence gate.

5DecisionBranches on the confidence threshold
High confidence

Goes to the licensee of record.

Low confidence

Picks up a broker review first.

Licensee approval

The date is held with its quoted clause, its notice path and the confidence.

Each correction a licensee makes is counted in the evaluation.

What should not run autonomously

Human approval stays in control

Outside the boundary — human approval required8 items
Waiving, removing or extending a contingency.
Drafting an amendment, addendum or extension.
Advising on contract meaning or a party's options.
Transmitting or confirming wire or payment instructions.
Automation boundaryAgent acts unaided
Compute candidate deadlines with the governing clause quoted.
Track document receipt against the contract checklist.
Escalate approaching and lapsed deadlines to the licensee.
Assemble and retain the transaction file to the state retention schedule.
Writes land inside the boundaries agreed at implementation, and never on a held act.
Selecting or recommending a settlement-service vendor.
Releasing or directing release of earnest money.
Declaring a transaction clear to close.
Communicating on the licensee's apparent authority.

Value

Where AI adds value

The same four claims, placed at the point in the workflow where each one applies.

Where the value landsValue 01 – 04
Each active contractFrom the executed instrument
03Coordination

Compute from the instrument

Draw on the executed text, the form version in force and the escalation rules set by the brokerage.

01Approved path

See the deadline before it passes

Routine date computation and document tracking arrive already done.

02Human review

Send review to the dates that bite

Notice-dependent deadlines and low-confidence dates are marked, so the licensee's read starts where a lapse costs most.

04Build an evidence trail

Each computed date keeps the clause it came from and the licensee action that followed.

Integrations

Typical integrations

Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

Agent controls

Six layers between the model and the deadline

Each control wraps the one inside it. What each layer misses is named in the failure-mode map directly below.

How Nestack evaluates it

Evaluate the coordination workflow — not only the date on the calendar.

Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Affected slices

The all-contract rate hides the cohort

A missed-deadline rate that reads acceptably across all contracts sits on cohorts that miss at several times that rate, and on cohorts well under it. Nestack reports the rate by slice, not only in total.

Evidence-linked improvement

A cycle ends in a test, not a fix

A passed date cannot be un-passed, and renegotiating it is the counterparty's choice — so the cycle closes only once the miss is a regression case.

Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect

Missed-deadline rate rises in a contract cohort.

02Diagnose

The base date is checked first, then the form version and the day convention, until the cause narrows to one.

03Improve

The correction is version-stamped, and dates computed off the old rule are recomputed.

04Verify

Release waits on the affected regression cases passing again.

05Learn

The case becomes a standing test and a line in the escalation rules.

Learn → DetectThe return edge. What catches the next miss is longer by this case.
