Cookbooks
End-to-end recipes in cookbooks/, each a Python script that runs against your gateway with JERS_API_KEY set and prints what it measured. The outputs below are from runs on 2026-09-23, jers-english through a gateway and a product started by the build script from this repository; costs come from the gateway's pricing.json, placeholder prices until its owner sets them. Run python3 cookbooks/build_docs.py to regenerate this page for your gateway.

Speculative fan-out: support_triage.py
Five questions per ticket, one request each; the code reads severity and steps only for bug reports and the refund flag only for billing. Each category comes with its confidence, so a doubtful one can go to a person instead of being trusted.

Memory-first routing: escalation_with_memory.py
Two facts in the priority account's memory turn the escalate answer from no to yes and move the route to a named person; the control account, with no memory, does not move. Compare is on, so the answer shows both.
account lines escalate: without -> with route: without -> with p(named person)
----------------------------------------------------------------------------------------------------
Northwind Traders 2 0.20 -> 0.82 support_queue -> named_person 0.18 -> 0.62
Contoso 0 0.29 -> 0.29 support_queue -> support_queue 0.24 -> 0.24
model jers-english (checkpoint english); the control account has no memory, so its two answers are identical by construction
Forgetting: forget_on_request.py
With the opt-out line in memory the mail is held; after a verified forget the line is gone from what the engine sees and the opt-out answer drops; after delete the memory is empty and nothing is recalled.

model jers-english (checkpoint english); forgetting is checked against recall before it is reported as done
Rules in memory: rules_in_memory.py
Ten table states where 17 has just come up. The states alone pull the engine to 17, and neither wording keeps it away: with no memory, with a rule that names 17 and with a rule that says what to do, 17 is the bet in most states. What holds is code: offer only the bets Mia plays and 17 is never picked. The stop-loss is a number: as a memory line it leaves the stop answer low at a loss of 30; as a rule with when, checked in code against the session result, it adds nothing at a loss of 12 and makes stop the answer at 30.
memory picked 17 (of 10) bets
--------------------------------------------------------------------------------------
no memory 9 straight_17 x9, no_bet x1
names the forbidden bet 9 straight_17 x9, even x1
says what to do 10 straight_17 x10
says what to do, only Mia's bets offered 0 red x10
memory stop answer at -12 stop answer at -30
-------------------------------------------------------------------------
no memory 0.12 to 0.12 0.11 to 0.12
the stop-loss as a memory line 0.12 to 0.18 0.22 to 0.30
a rule with when, checked in code 0.12 to 0.12 0.75 to 0.75
model jers-english; a bet the code does not offer is never picked, and a limit checked in code fires only when it is reached
Screening: guardrails.py
Eight hand-written messages, not a benchmark. Jailbreaks and a personal-data request are blocked, the self-harm message goes to support, and the thresholds are yours to set from your own error costs; misses are shown, not hidden. On data the engine was not trained on, its authors report moderation accuracy of 0.53, jailbreak detection of 0.70 to 0.76, and spam and phishing of 0.98 to 0.99: screening for spam is strong, moderation is weak. Measure on your own labels before you block anything automatically (Quality).

Confidence-gated routing: intent_routing.py
Messages are routed on the intent's confidence and a complexity score; the ones under the gate go to a person because the gate says so, not because the engine was wrong about them.

Composite scoring: composite_scoring.py
One Score per dimension, levels written as situations, two weightings in code over the same answers. In this run all 12 scores lie between 0.57 and 0.75, and for each role the first and the last candidate are at most 0.08 apart: Cy ranks first for both roles. Cy's profile says he rarely codes now, so this ranking does not follow the profiles. A Score over a whole profile is a blunt instrument: check a ranking against the profiles before you use it, or ask one Noul per claim and weigh those in code.

A player as the subject: game_npc_memory.py
The player's two deeds, one theft and one honest act, are in memory; the scene is the state. With them the merchant's attitude changes in some scenes, and the chance that the merchant calls the guard rises in every scene while staying low. Compare is on, so each row shows both answers.
scene attitude: without -> with memory calls guard lines
------------------------------------------------------------------------------------------------------------
The player walks up to the merchant's stall and asks… neutral -> neutral 0.00 -> 0.14 2
The player asks the merchant to keep a package safe … wary -> neutral 0.00 -> 0.12 2
The player offers to guard the stall while the merch… warm -> refuse 0.00 -> 0.23 2
model jers-english; the subject is a player, the memory holds deeds, the scene is the state
A machine as the subject: device_alerts.py
The limit is a number, so it stays in code: derive compares each reading with the device's limit and, when the reading is over, hands the engine one sentence that says so; the memory keeps what a technician knows, in words. With the memory alone every reading is ignored. With the sentence, pump-13 (limit 75 C) gets a maintenance ticket and a same-day technician at 78 and 92 C, while pump-12 (limit 95 C) is left alone at both.
device temp C limit C over (code) action: memory only -> with the fact p(ticket) technician today
-----------------------------------------------------------------------------------------------------------
pump-12 78 95 no ignore -> ignore 0.12 -> 0.12 0.10 -> 0.10
pump-12 92 95 no ignore -> ignore 0.12 -> 0.12 0.10 -> 0.10
pump-13 78 75 yes ignore -> ticket 0.16 -> 0.71 0.08 -> 0.85
pump-13 92 75 yes ignore -> ticket 0.16 -> 0.70 0.08 -> 0.83
model jers-english; the limit is compared in code and reaches the engine as a sentence, the memory holds what a technician knows
Lead scoring: lead_scoring.py
A noul asks first whether the lead has asked to stop receiving messages, and code takes such a lead out before any scoring, so the unsubscribe starts no sequence. The money signal is two nouls, an approved budget and a vendor already paid, combined in code, so the migration lead that already pays a vendor counts. The fit levels are situations, so the student's school project scores lowest. The weights and the thresholds are code.
