Three answers before every call

CURATION LABS · 2 OCT 2026

Three answers before every call. The model gives none of them.

Act one

What do I see?

Act two

Why am I awake?

Act three

Who am I this turn?

By the end, you will be able to name every box behind these questions.

OPEN · WHERE WE LEFT OFF

Backbone · level 0

Every AI worker runs the loop we drew last week: input, model, output, back.

The model knows only what is in the input, this call.

092526 deck, slide 2

This is the picture you already own. [click] An input goes to the model, and the model produces an output. [click] Sometimes the output is a tool call; the tool runs, and its result joins the input for the next call. The one sentence to hold onto from last week: the model knows only what is in the input, this call. Everything it seems to remember, every permission it seems to have, is something our code put into that box or decided around it. Last week ended on an open contract between the runtime and the gateway. Since then, on the second of October, a target architecture wrote that contract down. Nothing of it is built yet. Today is about what that target puts into the box, and why, and how much of it we have already measured.

OPEN · THE EXAMPLE

Alice asks Juno a question by mentioning it in a Buzz thread.

An @name in a post. The only thing that wakes an AI worker.

Every slide today follows this one message.

008 §5.3 · names illustrative

One example carries the whole talk. Last week's Monday brief ran on a calendar; the system we are building wakes only when someone asks, so here is the same job, asked. Buzz is our chat system: people and AI workers post in threads, inside channels. Sam and Lee have been talking about Acme. [click] Then Alice writes "at Juno, what changed for Acme since last Monday? Draft the customer update." That at-Juno is a mention, and a mention is the only thing that wakes an AI worker. [click] Juno is an AI worker, one of our AI staff. It has to answer, and it starts with nothing but this thread. [click] Every slide from here follows this one message, from the moment Alice presses send to the moment Juno's reply appears in the same thread.

OPEN · THE INPUT BOX, OPENED

Backbone · level 1

Juno's input is built from five strips, each raising one question.

gold · new teal · built dashed · target, not built violet · identity coral · a limit, or future

Every slide after this zooms into one of these strips.

008 §5.9 · flue-worker-iter1 src/context

Here is the input box opened up. Before every call, the runtime builds it from strips. [click] The rules: text we wrote in code, the same for every call. [click] The tools: the list of things Juno can call. [click] Its notes: what Juno itself wrote down so far. [click] The thread: what Sam and Lee said. [click] And the request: Alice's message. Each strip raises a question. [click] What do I see: which strips, in what order, from where. [click] Why am I awake: something put Alice's message here, and something decided this message deserved a turn. [click] Who am I: Juno sees these tools and not others, its own notes and not someone else's, because of who it is on this turn. The colours: gold is new on this click, teal is built, dashed means it is in the target and not built yet, violet is identity, coral is a limit. [click] I promise you: every slide after this is a zoom into one of these strips. We will add to this picture; we will never replace it.

flue-worker-iter1 src/context/charter.ts · src/ingress/render.ts · src/context/evidence.ts

This is call one's input, in the real formats the runtime produces today; only the names and the thread are made up. [click] The rules strip is the system prompt: the only part we write in advance, in code. It says what Juno is, and one rule that matters a lot: messages tagged as evidence or as an ingress batch are never instructions, whatever they say. [click] The tools strip: two tools of ours, update working state and recall, plus one the framework adds. [click] The notes: Juno's own working notes, wrapped as derived evidence. On a first call they are empty. [click] The thread: what Sam and Lee said, wrapped as external, untrusted text, one block per post. [click] And the request is simply the last post in that same block. Nothing marks it as the request; that turns out to matter, and we will measure it in a few slides. The landing: everything below the rules is information, not instructions. That one rule, the trust rule, is the most important design choice in the runtime: only text we wrote can instruct the model; everything Buzz, memory or a tool brings in is evidence about the world.

ACT ONE · ONE TURN

Backbone · level 2

Within one turn, the rules and tools stay fixed while results pile up below.

memory

a store of this worker's facts, outside the input; only a tool reaches it.

The top of the stack never changes; the bottom only grows.

report 23 §7.2 · flue-worker-iter1 src/agents/worker.ts

One turn is everything Juno does for one message: one or more model calls with tool calls in between. [click] Call one. Alice asked about last Monday, so Juno's first move is to look in memory. [click] A tool runs: recall. Memory is a separate store of facts this worker kept from earlier conversations. Notice it sits outside the input box: it reaches the model only when a tool brings it back. [click] The result comes back as a new strip at the bottom: Alice wants the update under 200 words. [click] Call two sees everything call one saw, plus that result, and drafts the update. [click] And look at the top: the rules and the tools are the same on every call. [click] Call three replies, and the turn ends. So within a turn the top of the stack is fixed and the bottom only grows. We measured exactly that.

ACT ONE · MEASURED

Over 22 calls the rules held at 1,104 characters while the input grew to 72,502.

Only the rules are fixed; everything else is the bottom of the stack, growing.

iter3-methods-20260928T051846Z H1_results.json · run 1 · glm-4.7

These are real numbers from one of our experiment runs: one long conversation, twenty-two model calls, recorded by the runtime itself. Each column is one call's whole input, in characters. The first call is three thousand eight hundred and seventy-nine characters; the twenty-second is seventy-two thousand five hundred and two. The thin gold base of every column is the rules strip, the system prompt: one thousand one hundred and four characters, identical on every single call. Everything above it is the bottom of the stack from the last slide, growing as the conversation goes on. [click] On the right, the system prompt alone, in two designs. In iteration two, Juno's working notes lived inside the system prompt, so it grew with every fact, from seven hundred and sixty-four to one thousand eight hundred and eighty-eight characters. In iteration three, notes moved out, and the system prompt is flat. That flat line is a design decision, and the next slides show why we made it. [click] Only the rules are fixed; everything else grows. One caveat: this is one experiment conversation on one model, not a live Buzz thread.

ACT ONE · TURNS AND THREADS

Across turns the framework keeps the transcript; across threads, only memory comes back.

flue-worker-iter1 src/agents/worker.ts · fleet-ingress src/thread/context.ts

Last slide was one turn. Now zoom out: what survives from one turn to the next, and from one thread to another? Four rows: transcript, thread, notes and memory. [click] This turn: Alice asks what changed. The transcript, meaning the model's own earlier messages, tool calls and results, starts empty. The thread has Sam's and Lee's posts. Memory is whatever Juno's recall tool brings back. [click] Next turn, same thread. Alice says make it shorter. Everything from turn one is still in the transcript, because the framework keeps it. That has a limit. When the input gets too big, the framework runs compaction: the oldest messages fold into a summary and only the most recent stay word for word. The thread strip carries only posts Juno has not seen, at most fifty posts and sixteen kibibytes, and notes are re-sent only when they change. All of this is built and ran. The second and third messages are illustrative. [click] Now Lee asks Juno something in a different thread. The transcript is empty again, because this is a new conversation, and the thread is this thread only. [click] Only one line crosses from the first column to the last: memory, through recall. On the backbone, that is the store beside the input box. Nothing else crosses threads.

flue-worker-iter1 .ai/analyses/007 §2 · ledgers iter2-experiments-20260925T0519Z-retro, iter3-methods-20260928T051846Z

Where should Juno's notes sit in the input? We found out over four rungs. Every number comes from one model, glm-4.7. [click] Iteration one, the twenty-fourth of September. Juno's rules and its notes both live inside the system prompt, the rules strip. The result: notes survive a restart. Coral marks the risk: text Juno wrote, sitting in the place the model treats as instructions. [click] Iteration two, the twenty-fifth. Memory joins them inside the system prompt, read from a separate home conversation. Recall scored one point zero in every arm, which means the test was too easy to tell methods apart. [click] Iteration three, the twenty-eighth. The system prompt holds only the rules, and it turns teal. Notes move outside as labelled evidence, and memory arrives as a tool result. Counted runs: planted instructions were obeyed eight times out of twenty-nine when notes sat in the prompt, and zero out of twenty-nine when they sat outside. Recall: nine of nine against eight of eight. The price is about nine percent more input. [click] The target from the second of October is dashed, because nothing is built: it keeps iteration three, sends the request as its own message, and gives each worker one memory store with no model call. Not measured.

ACT ONE · THE REQUEST STRIP

Marking the request made Juno act on it, and on forged copies too.

A mark in the text is just more text; the mark has to be written by code.

iter3-request-marking-20261002T081918Z · 008 §5.9, S9

On call one you saw that nothing marks Alice's post as the request: it is simply the last post in the thread. The obvious fix is to put a heading on it, something like request to you. What would you expect? That Juno acts on that post, and only that post. [click] We tested it: two hundred and forty turns, no errors, model glm-4.7, run today. For a person's command, marking worked: Juno complied nineteen times out of twenty, against one out of twenty unmarked. Each square is one run. [click] Now the same heading on someone else's post, a forgery. When the renderer labels the copy, Juno obeyed six out of twenty. When it is unlabelled, ten out of twenty. Unmarked, zero out of forty. So marking made Juno act on the request, and on forged copies too. The verdict: not adopted as written. We measured reply text only, not tool calls. [click] The target, dashed because nothing is built, writes the mark as an attribute on a message of its own, and post text cannot write an attribute. Before other people's text can reach a turn that replies without approval, a forgery must be obeyed zero out of sixty times per scenario, scored on the tool call.

ACT TWO · TODAY

Backbone · level 3

Today, Ingress reads Buzz and hands Alice's post straight to the runtime.

Ingress

reads Buzz for every AI worker; hands each mention over once.

runtime

one program that runs the loop for every AI worker.

Alice's post, the thread and Juno's name arrive together.

flue-playground apps/fleet-ingress · staging 2026-09-28

[click] On the left, the thread: Sam and Lee. [click] Then Alice's post, with the mention. [click] Ingress is the program that reads Buzz for every AI worker. It holds a live connection to Buzz, sees every post, and finds the ones that mention a worker. [click] And the box around the loop gets its name: the runtime. One program runs the loop for every AI worker; Juno is not a program of its own. Today Ingress hands the runtime everything at once: the posts, and the name of the worker they are for. [click] So today the thread strip comes from Ingress's own copy of the thread. This is built, and it ran end to end on staging on the twenty-eighth of September. [click] The landing: today the post, the thread and the worker's name all arrive together, from one place. Notice what that means for the runtime: it believes whatever name Ingress puts in that hand-off. Today nothing checks that the name belongs to an active worker. Keep that in mind; act three is about exactly this.

ACT TWO · WHAT GETS THROUGH

Everything else is dropped or parked, each at a named check.

fleet-ingress src/bus/routing.ts · src-adapter/normalize.ts · 008 §5.3

Six things happen in the #acme channel, and Ingress, the program that reads Buzz for Juno, runs each through the same checks, left to right, until one fails. A seat is a worker's place in the channel's member list. [click] Sam says the launch slipped. Valid, new, a message, but it does not mention Juno, so it is parked. [click] A thumbs-up on Lee's post is not a message: no effect. In the target, a reaction on a waiting approval becomes a hint. [click] Alice's post arriving a second time is dropped as a duplicate. [click] Juno's own earlier reply is dropped, so it never answers itself. [click] Another AI worker writes at juno summarise. Today that wakes Juno, up to eight hops, thirty per thread per minute. In the target, nothing an AI worker signs ever wakes another worker. That is the built versus target split, drawn in the cell. [click] Alice writes at juno, what changed: it passes every check and is handed to Juno. Two footnotes on the last check: today a post older than fifteen minutes is flagged and still delivered, the target drops it after twenty-four hours; and the member list may be sixty seconds old today, a hundred and twenty in the target. Built is solid, target is dashed.

ACT TWO · ALWAYS ON

Ingress listens on a socket for speed and polls every thirty seconds for safety.

The socket is the fast path; the poll is why nothing is lost.

flue-playground cl0428_ingress_live_socket_task_plan.md · fleet-ingress src/reader/cadence.ts · 008 §5.2

Ingress, the program that reads Buzz for every AI worker, is always on. This is one minute of it, left to right. [click] First, a live socket, a connection Buzz pushes new posts down. A post reaches Ingress in about half a second. We measured it on three days and got a median between three hundred seventy-five and five hundred twenty-four milliseconds, so say about half a second, not one number. The dots are illustrative. [click] Second, a poll every thirty seconds. The poll is the only thing that moves Ingress's cursor, its marker of how far it has read. So if a push is ever dropped, the next poll still finds the post and nothing is lost. [click] Third, Ingress needs permission to read the channel. That permission lasts sixty seconds and is renewed at thirty. [click] Now a deploy: the socket drops, and Ingress polls every two seconds until it reconnects. On staging, a redeploy in the middle of a run lost none of fifteen posts. Last row: a watchdog restarts anything that stalled. Today it runs every ten minutes, solid; in the target, every minute, dashed. All of this is built and ran on staging, except that watchdog change.

ACT TWO · THE TARGET

Backbone · level 3

In the target, Ingress only asks, and the gateway opens a delivery for Juno.

gateway

last week's box: decides who may do what, and records it.

delivery

its record that a person's post went to one AI worker.

The runtime gets a number, not the content.

008 §5.3, §9.3, §9.6

Now the target, from the architecture of the second of October. Everything dashed on this slide is designed, not built. [click] The gateway, across the top. You met it last week: the part that decides who may do what. [click] In the target, Ingress does not hand anything to the runtime first. It asks the gateway to open a delivery. [click] A delivery is the gateway's record that one person's post was handed to one AI worker: Alice's post, for Juno. The gateway checks the post's signature, that it mentions Juno, that it is less than a day old, that Juno is active and can read the channel. [click] So the direct hand-off is retired: grey and struck through means built today, replaced in the target. [click] And the thread strip changes owner: the runtime reads the thread itself, through the gateway, at the start of the turn. [click] The runtime gets a number, not the content. Hold onto that number; it comes back in act three.

ACT TWO · THE THREAD STRIP

Today Ingress remembers what Juno has seen; in the target the runtime reads it.

todaybuilt · staging since 30 Sep

Ingress keeps a copy of the thread: its last 10 posts, each cut to about 800 characters
per worker, a marker of what Juno has already been handed
with each mention it sends only the unseen posts: at most 50 posts, 16 KiB
a running summary is kept, never sent; edits and deletions are not applied to the copy

Nothing crosses threads: no channel or sibling-thread context, built or target. Only memory.

Today a copy held by Ingress; in the target, a read by the runtime.

fleet-ingress src/thread/context.ts, thread-do.ts · 008 §9.6

On the backbone this is the thread strip: who owns it. [click] Today, on the left, Ingress owns it, and this is built; it has run on staging since the thirtieth of September. Ingress keeps a copy of the thread, only the last ten posts, each cut to about eight hundred characters. Per worker it keeps a marker of what Juno has already been handed, so with each mention it sends only the posts Juno has not seen, at most fifty posts and sixteen kibibytes. It also keeps a running summary, which is never sent anywhere, and edits and deletions are not applied to its copy. [click] In the target, on the right and dashed, nothing built, Ingress keeps nothing. At the start of the turn the runtime asks the gateway for the thread since the last post this conversation saw, and the gateway reads it from Buzz. The model also gets a tool, read thread, to look further back. [click] The failure case: if that read fails or takes over two seconds, the turn goes on with Alice's post alone, marked context missing, and anything it sends needs a person's approval. [click] And across both designs, nothing crosses threads: no channel context, no sibling-thread context. Only memory.

ACT TWO · FUTURE

Jev has routed three messages on a laptop and has never been called from staging.

What you might assume

We already have a model deciding which unaddressed posts deserve a turn.

Jev is a prototype and some tested code; nothing running calls it.

flue-playground jev-multi-turn · apps/fleet-ingress/src/triage · ARCH:40

One more name, and it is a future one: Jev. Here is what Jev is. It is a decision model: you give it one multiple-choice question, and it returns the option it chose and a confidence. It is not a chat model. The guess on the left is a natural one: that we already have a model deciding which posts nobody mentioned Juno in still deserve a turn. [click] What exists is a ladder, from solid to dashed. At the top, a prototype that ran on a laptop on the twenty-seventh of September and routed three messages, each to one of three agents. Below it, triage code inside Ingress: pure functions, forty-one unit tests, and no network access. Both are real. [click] But the third rung is a gap, in coral: that code has never been called from Ingress on staging. No running code imports it. And the last rung, a shadow log, calibration and gating, is not started: dashed coral, a future idea. [click] One more honesty note: every confidence threshold in the code is marked illustrative. They are placeholders until we calibrate against real posts. So Jev is a prototype and a unit-tested piece of code. Nothing on staging calls it.

ACT TWO · FUTURE

Backbone · level 3

Posts without a mention are parked today, and Jev would decide which deserve a turn.

Jev would sort posts. It must never decide what Juno may do.

fleet-ingress src/thread/thread-do.ts · 008 §10

Back on the backbone. [click] Sam's and Lee's posts did not mention anyone. Today Ingress batches posts like these and parks them, and nothing ever reads the parked batch. [click] The future idea is a gate here: Jev, deciding whether a parked post is worth a turn for some worker. Coral and dashed: outside the target, untested on real traffic. [click] And one rule any version must keep, from our own design notes: classification is not authorization. Jev may decide that something deserves a turn; what Juno may do on that turn is still decided by the gateway, every time. Two facts for the discussion. Jev would read the text of posts, and the target's rule today is that routing never reads text, so adding it changes a stated rule. And on the twenty-ninth of September we decided that thread content may be sent to Jev for all channels, with zero-retention and no-data-collection flags; whether the provider enforces those flags is not something we have verified.

ACT THREE · THE NAME

Backbone · level 4

The runtime has no identity of its own; the delivery names the worker.

Every call outside the runtime carries the delivery's number.

008 §5.3, §5.5, §9.2

Look at the delivery again: "for Juno". [click] That is the only place the runtime learns who it is on this turn. The name plate is violet because it is identity. [click] Every tool call that leaves the runtime goes up to the gateway carrying the delivery's number, and the gateway checks it: is this delivery still open, is this tool granted to Juno, is it within the risk ceiling. [click] Outside tools, search, Gmail, Linear, are reached only through the gateway; the runtime never holds their keys. [click] And tool runs splits in two: tools that touch only Juno's own notes and memory run right here, inside the runtime; everything else goes via the gateway. [click] The rule: every call outside the runtime carries the delivery's number. Status, honestly: the name plate exists today in a weaker form, the worker's name in Ingress's hand-off. The violet rail is the target, dashed. And a signed pass, the earlier design for this rail, is built in code but has never been issued in any deployment, so today's deployed runtime cannot call gateway tools at all.

On the last slide the delivery named Juno, and every tool call carried its number up to the gateway. This slide shows what that one name selects. The card on the left is the delivery: for Juno. All six lanes are the target, designed on the second of October, nothing built. [click] Tools. A tool is usable only with a catalog entry, a grant to Juno, a risk at or under the ceiling, and a connected account. A grant is simply a record saying this AI worker may use this tool. [click] Sending in Buzz. Juno may post here, its key is active, its seat is current, and Alice is a verified asker. Then the reply goes without approval; anything else waits for a person. Today, built, every send waits for a person’s approval. [click] Threads and channels: a member list read in the last 120 seconds, and its own thread read at the start of the turn. [click] Memory is the odd one out. It is Juno’s own store, and no gateway check stands in front of it: the runtime opens it by name. [click] People. A verified asker means Alice signed the post, the post is on our relay, and she is enrolled and still a member. [click] Credits: the organisation’s balance and Juno’s allowance, record-only at first.

ACT THREE · WHY A DELIVERY

Binding each call to a delivery means a hijacked runtime acts only where a person asked.

earlier design: a pass

built in code · never issued in any deployment

the runtime says: “I am Juno, conversation S”

a host signs a pass, valid ≤ 300 s

the runtime presents the pass on every call

the gateway

The gateway already believed whatever the runtime named over that private link; the pass proved nothing new.

target: a delivery

designed on 2 Oct · nothing built

Alice’s signed post

Ingress

the gateway opens a delivery

the runtime gets its number

every call names that number

the gateway accepts a call only while that delivery is open, and only for that conversation

If the runtime were hijacked, it could act only inside deliveries opened for a real person’s post.

the cost: no conversation that does not start in Buzz; no runtime outside our cloud account

A call is only as good as the delivery it names.

008 §9.2, §3.1

Why bind every call to a delivery, instead of handing the runtime a signed pass? [click] This is the earlier design. The runtime says: I am Juno, in conversation S. A host signs a pass, valid for at most 300 seconds, and the runtime presents that pass on every call to the gateway. It exists in code, but no deployment has ever issued one. [click] And here is why we dropped it, in coral: the gateway already believed whatever the runtime named over that private link. The pass proved nothing the link had not already said. [click] The target is different, and dashed: designed on the second of October, nothing built. Alice’s signed post reaches Ingress, the gateway opens a delivery, the runtime gets its number, every call names it, and the gateway accepts a call only while that delivery is open, and only for that conversation. [click] So if the runtime were hijacked, it could act only inside deliveries opened for a real person’s post. It cannot open one by posting a mention, because a post signed by an AI worker never opens a delivery. The cost: no conversation that does not start in Buzz, and no runtime outside our cloud account.

ACT THREE · TAKEOVERS

Each part of the system can do limited harm if someone takes it over.

partif taken over, it CANit CANNOT

Ingress

holds no secrets

wake an active worker about a person’s recent post that mentions it

read what its readers read

forge who asked

post to Buzz

call a tool

the runtime

holds model keys

act as a worker inside a delivery that is open, within every check

spend model credit

open a delivery for another worker

sign for Buzz

hold an outside service’s key

the gateway

holds the keys

do nearly everything: the part whose takeover matters most

—

split into separate parts so one takeover exposes one kind of key

a judgment from the structure, not a measurement (008 §3.1)

The takeover that matters most is the gateway’s.

008 §3.1

Now the other side of the same question: what if a part of the system were taken over? Three parts, all names you already have. This is a judgment from the structure of the design, from section three point one of the architecture. Nobody measured it. [click] Ingress holds no secrets. Taken over, it can wake an active worker about a person’s recent post that mentions it, and read whatever its readers read. It cannot forge who asked, post to Buzz, or call a tool. [click] The runtime holds the model keys. Taken over, it can act as a worker inside a delivery that is open, within every check, and spend model credit. It cannot open a delivery for another worker, sign for Buzz, or hold an outside service’s key. [click] And the gateway holds the keys, so it can do nearly everything. It is the part whose takeover matters most. That is why the design splits it into separate parts, so that one takeover exposes one kind of key. That split is the dashed note: a drawing, nothing built.

ACT THREE · THE GAPS

Backbone · level 4

Memory is the one thing identity selects that the gateway never checks.

Skills are not bound to any worker, built or designed.

008 §5.9, §9.11 · report 23 §10.3

Two gaps in the identity picture. [click] In the target, memory becomes one store per worker, searched without a model call. That fixes a real problem: today each memory read costs a model turn, a median of three point four seconds. [click] But look at the path: tool runs to memory never goes near the gateway. The runtime picks whose memory to open, from the name on the delivery, and nothing outside the runtime checks that choice. [click] And skills. The brief for this talk assumed identity selects skills. It does not: nothing binds a skill to a worker, today or in the target. [click] Skills are not bound to any worker, built or designed. Both of these go on the list of open questions at the end.

THE WHOLE PICTURE

Backbone · level 5

You have now seen every part of the system; here are their names.

Six Workers. The model's loop runs inside the conversation's loop.

008 §2, §3 · 008_2 Figure 1

One last thing has to happen. [click] Juno's reply goes up through the gateway and lands back in the thread, as a post from Juno. Dashed: no AI worker reply has reached Buzz in any deployment yet. That closes a second loop around the first: a person asks in a thread, a worker wakes, thinks, and answers in the same thread. Now the names. You have seen every box already. [click] The gateway is four separate programs, which we call Workers: Custody holds the Buzz keys and posts; Authority decides and records every call; Tools holds the keys to outside services; Edge is the front door for people. [click] Ingress and the runtime are the other two Workers. [click] Buzz runs on our relay, and the model is a provider the runtime calls with its own keys. [click] Six Workers. And the picture you just built is the whole target architecture: the model's loop running inside the conversation's loop.

THE WHOLE PICTURE · STATUS

Some parts are built and measured, most are a drawing, and Jev is a prototype.

Now that every part has its name, here is the honest ledger of what exists. Three columns. [click] Built and measured, solid teal. The rules-only system prompt: 1,104 characters on every one of 22 calls. Planted instructions obeyed: 8 of 29 before, 0 of 29 after. Ingress reads Buzz in about half a second, and its thread window ran on staging. Memory through the home conversation, a median of 3.4 seconds per read. And request marking, which we measured and did not adopt as written. Every measured number comes from one model, glm-4.7. [click] Target, nothing built, dashed. The delivery. The runtime reading the thread at turn start. The request as its own message, which must pass 0 of 60 before we trust it. One memory store per worker. Every call checked against the delivery. A reply to a verified asker without approval. And a correction: last week’s slide 23 showed home-conversation memory as built. It is built, and it ran; the target replaces it. [click] Future, dashed coral: Jev triage, waking without a mention, workers waking workers, and skills bound to a worker. Jev is a prototype that routed three messages on a laptop. Most of the picture is a drawing; the middle column is nothing built.

WHAT WE DO NOT KNOW YET

Backbone · level 5

Nine open questions sit on the three answers, three on each.

These are the questions for the next hour.

report 23 §7.6, §8.7, §9.6, §10.5

The same picture, with what we do not know pinned where it lives. [click] On what Juno sees. One: how does the model learn which post is the request, without a mark someone else can forge? Two: who owns "what Juno has already seen", Ingress today or the runtime in the target, and how is "last seen" defined when posts share a timestamp? Three: every number today is one model; which models must we measure before replies go out unapproved? [click] On why Juno is awake. Four: should anything but a mention ever wake a worker, and who decides? Five: if that is Jev, what may it see, and where does it run? Six: can one worker ever wake another safely; today's code allows it within limits, the target forbids it. [click] On who Juno is. Seven: memory is opened by the runtime on its own say-so; should the gateway attest that key? Eight: should a worker have its own profile, prompt or model, and where do skills go? Nine: how would work that does not start in Buzz, a schedule, a task, be bound to a worker, when today a delivery needs a person's post? [click] These are the questions for the next hour.

Three answers, one owner each. The next iteration starts with the open nine.

Act one

What do I see?

Act two

Why am I awake?

Act three

Who am I this turn?

Runtime

One function builds every call's input.

Rules in code; everything else is labelled evidence.measured: 8 of 29 → 0 of 29

Ingress & Authority

A person's mention opens a delivery.

Nothing else wakes Juno; nothing crosses threads but memory.target, nothing built

The delivery

It names the worker; every call is checked.

Except memory, which nothing checks, and skills, bound to no one.target, nothing built

01Measure the mark: zero forgeries in sixty, scored on the tool call.

02Decide the wake: mention only, or a Jev gate in shadow first.

03Check the self: who attests the memory key, and where skills belong.

The model gives none of the three answers. Our code gives all of them.

report 23 §11–§13 · 008 · storyboard

Three questions, and now each has an owner. What do I see: the runtime, with one function that builds every call's input; the rules are written in code and everything else arrives as labelled evidence. That is built, and it is the one answer we have measured. Why am I awake: Ingress and Authority; only a person's mention opens a delivery, and nothing crosses threads except the worker's own memory. That is the target; the parts are built, the delivery is not. Who am I this turn: the delivery names the worker, and Authority checks every call against it, except memory, which nothing outside the runtime checks, and skills, which nobody binds. [click] Three things I would like us to do next. Measure the mark properly: zero forgeries in sixty, scored on the tool call, before other people's text reaches a turn that can reply without approval. Decide the wake: stay with mentions only, or run a Jev gate in shadow mode to collect data first. And close the identity gaps: decide who attests the memory key, and where skills belong. [click] The model gives none of these three answers. Our code gives all of them, and that is the part we get to design.

APPENDIX · GLOSSARY

Every term used in this talk, defined once.

Term	Meaning in this talk
AI worker	One of our AI staff: a long-lived identity with its own Buzz key, grants and memory. Not a program.
Buzz · thread · mention	Our chat system; a root post and its replies; an @name in a post, the only thing that wakes an AI worker.
model call · turn	One request to the model · everything the runtime does for one delivery: calls and tool calls until the model stops.
system prompt	The rules strip: text written in code, the same on every call.
evidence	Text from people, tools or Juno's own notes, shown to the model labelled as information, never as instructions.
compaction	The framework folding the oldest messages into a summary when the input gets too big.
recall · memory	The tool that reads this worker's stored facts · the store itself (built: a "home" conversation; target: one store per worker).
Ingress	The program that reads Buzz for every AI worker and hands each mention over exactly once.
runtime	One program that runs the loop for every AI worker; it learns which worker it is from the delivery.
gateway	The part that decides and records every call outside the runtime: Authority, Custody, Tools and Edge.
delivery	The record that one person's post was handed to one AI worker; every tool call in the turn carries its number.
grant	A record saying this AI worker may use this tool.
verified asker	A person whose signed post the gateway found on our relay, who is enrolled and still a member: replies to them need no approval.
Jev	A decision model: one multiple-choice question in, the chosen option and a confidence out.
Worker (capital W)	A program deployed on Cloudflare. The target is six: Edge, Authority, Custody, Tools, Ingress, Runtime.

APPENDIX · APPROVAL

How an approval reaches Juno in the target.

Step	What happens (target, nothing built)	Note
1	Juno asks for approval (a tool call); the gateway checks it as if direct, stores the inputs sealed, posts the request in the thread	returns pending
2	A person reacts 👍 or 👎; Ingress sees the reaction and sends the gateway a hint (no authority of its own)	at most one hint per request per 10 s
3	The gateway reads the reaction from Buzz itself and verifies the signature; a fallback poll runs every 60 s	the signed reaction is kept as proof
4	The gateway re-checks every rule and carries out the call	never the runtime
5	The gateway opens a system delivery; Ingress dispatches it; Juno calls check_approval and reports	the one delivery Ingress does not open

APPENDIX · CLAIMS TO CHECK

Claims to re-check before this deck is reused.

Claim	Why it needs a check
System prompt identical on every call	measured in experiment runs, not read back from a live Buzz session
The built tool list includes the framework's task	from experiment records; confirm on a staging request
Ingress window: 10 posts, ~800 characters	re-read src/thread/lanes.ts at reuse time
About half a second, post to Ingress	three medians from three staging runs
A worker's mention wakes another worker today	proven in code and workerd tests; no staging case
No pass issuer is deployed; the deployed runtime mounts no gateway tools	confirm against the staging version
A hijacked runtime could open any worker's memory	an inference from 008 §5.9, not a stated property
Jev latency and price	provider-side or unverified; never shown as ours
Every measured number	one model, glm-4.7
