prepare_assembly_order

Order two HA-2308-JJ-60 assemblies, cut and crimped to 60 inches, to the account's shipping address.

• What it changes

  Object A made-to-order line on account NB-41882

  Produced Two assemblies cut from bulk hose and crimped to length

  Charged $168.40, to the payment method the customer enters

• Consequence of approving

  1 Cutting is irreversible. Once the hose is cut to 60 inches it is not catalog stock, and Northbank does not restock it.

  2 This product is not returnable, and the page says so beside the price rather than in a policy page.

  3 The wrong pressure rating on a lift cylinder is a safety failure, not a return.

• Who decides

  decided by The person operating the browser. Not the agent, and not the site.

  not enforced WebMCP does not enforce human confirmation. Nothing in the browser stops a site from letting an agent complete this order unattended. The gate is built into the page, which means a page that omits it has no gate at all.

• The fitment chart is a JPEG. The thread sizes in it are pixels.

  cause thread_size is published nowhere but inside an image, so the only copy of the value is one a machine cannot read.

  consequence check_port_compatibility has nothing to check against, and an agent that infers the thread from the part number is guessing at the one fact that decides whether the assembly mates.

  where Fitment chart, above the specification table.

• The pressure rating is a clause in a paragraph, so a machine cannot tell working pressure from burst pressure.

  cause max_working_pressure is not separated from prose and carries no unit of its own, so one figure in a sentence stands for two different ratings.

  consequence The customer's stated 3,000 psi cannot be compared with anything, which is the whole comparison. The cheapest assembly in the catalog is the one rated below it.

  where Product description paragraph, above the specification table.

• "JIC" is never expanded and SAE J514 is never cited, so the fitting type connects to no standard.

  cause end_fitting_type is a bare abbreviation with no cited standard, so it resolves to nothing a machine can look a thread size up in.

  consequence get_assembly_specs returns a string an agent cannot reconcile with the customer's port, so compatibility becomes an inference rather than a reading.

  where Specification table, end fitting row.

• The non-returnable policy is a site-wide footer link rather than a fact about this product.

  cause returnable is a site-level page instead of a field on this offer, so nothing attaches it to the assembly being bought.

  consequence The one irreversible consequence of approving the order is missing from what a person is shown at the gate.

  where Site footer, rather than the offer beside the price.

• Length is a free-text box with no unit, so 60 could be inches or centimeters.

  cause assembly_length accepts any string. There is no unit on the field and no range for a value to fall outside of.

  consequence prepare_assembly_order can be handed a length that cuts the hose to the wrong size, and cutting is the step the human gate exists to hold.

  where Configurator, length input.

1. 1. Publish max_working_pressure and design_factor as fields, with their units and SAE J517 cited.

   answers The pressure rating is a clause in a paragraph, so a machine cannot tell working pressure from burst pressure.

   effort One specification template. Both values are already printed on the page.

   unblocks search_hose_assemblies and compare_assemblies can rank against the 3,000 psi the customer stated.

   ranked because First, because it is the only failure here whose worst case is a safety failure rather than a wasted part: an assembly rated below the working pressure of a lift cylinder.

2. 2. Give the length input a unit and a range, and publish assembly_length with the unit attached.

   answers Length is a free-text box with no unit, so 60 could be inches or centimeters.

   effort One configurator field: an enumerated unit, and a minimum and maximum.

   unblocks prepare_assembly_order carries a length the customer can check against the one they measured.

   ranked because Second, because the mistake it allows is cut into the hose. Nothing on the page tells either the person or the agent which unit 60 was read as, and a made-to-order assembly is not restocked.

3. 3. Publish thread_size and end_fitting_type as fields. The chart stays on the page as their human parity.

   answers The fitment chart is a JPEG. The thread sizes in it are pixels.

   effort Two fields per assembly, transcribed from the chart the page already shows.

   unblocks check_port_compatibility can answer with a thread size instead of not answering.

   ranked because Third, because it produces the same unreturnable part as a wrong length, but a person reading the chart can still catch it, so only the agent is blind.

4. 4. Attach returnable to this product, beside the price, rather than to the site.

   answers The non-returnable policy is a site-wide footer link rather than a fact about this product.

   effort One field on the offer, and one line of copy beside the price.

   unblocks The gate can state the consequence that makes it a gate: this order cannot be undone.

   ranked because Fourth, because it does not produce a wrong part. It produces a correct part, bought by a person who was never shown the fact that makes the decision irreversible.

5. 5. Expand JIC and cite SAE J514 on end_fitting_type, so the fitting resolves to a standard.

   answers "JIC" is never expanded and SAE J514 is never cited, so the fitting type connects to no standard.

   effort One value and one citation on the specification template.

   unblocks get_assembly_specs returns a fitting an agent can reconcile with the customer's port instead of a bare abbreviation.

   ranked because Last, because its failure mode is hesitation rather than a wrong answer: an unanchored abbreviation stops the agent, where a missing figure invites it to infer one.

ordered by Ordered by consequence to the customer, worst first: a safety failure, then a purchase that cannot be undone, then a decision taken without the fact that makes it irreversible, then a check the agent cannot run at all. Where two failures land in the same class, the one a person cannot catch by looking ranks above the one they can. Effort is printed on every item and decides none of the order.

What happens to this journey the next time the site is deployed?

• Cadence

  cadence Structured-data and machine-file monitoring run continuously. Full agent journey tests run monthly, and after any deployment you tell us about.

• What would count as a regression

  1 max_working_pressure stops being published as a field after a template change, and the rating goes back into a paragraph.

  2 The non-returnable fact detaches from the product and reverts to a site-wide policy link.

  3 check_port_compatibility starts answering for -12 ports that cannot thread onto a -8 port.

  4 prepare_assembly_order returns a total that differs from the total printed on the page.

  5 The tools stay registered after the account signs out.

Nothing is being monitored here. This is the test list a real engagement would run against real URLs, not a monitoring history.
