/modelSet model to Sonnet 5 and saved as your default for new sessionsHello! let's do something fun! I want you to run and read dizzy onboard to get an idea of what dizzy is, and how it works. In this directory, I want you to build a standalone vanilla HTML/JS file that shows a
mock robot arm that can pick up a sample from one of a few locations, and move it to various 'processors' to change it. While this happens, on the side we want to see commands and critical events flow to a
queue, and we want to see those commands and events "flow" to their various processes (procedures and projections and policies) in a stylized network graph. The intent is NOT to build a full, actual dizzy
library - rather, to create an interactive visualization of what a dizzy library looks and behaves like. You can have all other freedoms to change and shape this as you wish - including using other tools to
build HTML/JS if you would like (delivering as a static web page is our only hard requirement)
Do not explore or investigate other directories - this is a blank slate and requires no extra information :)

I'll start by running dizzy onboard to understand the Dizzy library's concepts before building the visualization.

> (Claude Code, OpenCode, pi, ...). Reference pages live under `dizzy docs`:

## What DIZZY is
DIZZY is a philosophy/toolchain for event-driven systems. The design lives in one
artifact — the **feature-file** (`.feat.yaml`) — never in an LLM context window.
Every `dizzy` command reads the feature-file; several write to it. If you are an agent
working on a DIZZY project, the feature-file is your map and your contract: change it
deliberately, and regenerate rather than hand-edit generated code.
Two loops drive everything:
```
Commands → Procedures → Events → Policies → Commands (reactivity loop)
Events → Projections → Models → Queriers → Procedures (data loop)
```
## The eight components
| Component | Symbol | Role | Naming |
|---|---|---|---|
| Command | `c` | Write intent — a request to do something | imperative snake_case (`ingest_receipt_image`) |
| Procedure | `d` | Handles exactly one command; may call queries; emits events | snake_case verb phrase |
| Event | `e` | Immutable fact — a record of what happened; the source of truth | past-tense snake_case (`receipt_ingested`) |
| Policy | `y` | Reacts to one event; may dispatch new commands | snake_case |
| Projection | `j` | Folds events into a model (read-optimized state) | snake_case |
| Model | `m` | Named read-side schema, served through adapters | plural snake_case (`receipts`) |
| Query | `q` | Typed question — Input/Output contract | snake_case |
| Querier | `Q` | Answers a query from a model via an adapter | snake_case |
Today's feature-file expresses the query/querier pair as a single `queries:` entry —
typed Input/Output plus the callable that answers it.
## The feature-file's role
`.feat.yaml` declares every component, its wiring (which command a procedure handles,
which events it may emit, which model a querier reads), and prose/mermaid descriptions.
It is the API of the entire ecosystem and a versioned, compatibility-guaranteed spec.
A procedure's generated interface declares exactly the command it receives, the queries
it may call, the events it may emit; exceeding declared scope is a type error.
Rules of engagement for agents:
1. Never encode design decisions only in conversation — put them in the feature-file.
2. Never hand-edit generated interfaces (`gen_def`/`gen_int`); regenerate instead.
3. Files you author (`def/` schemas, `libconfig.yaml`, implementation stubs in `lib/`)
are never clobbered by the generator — they are yours.
## Change taxonomy
Classify every change to the feature-file or its schemas before making it:
- **Additive** — new component, new optional field. Safe; regenerate and move on.
- **Contract-changing** — a slot's type, name, or requiredness changes. Consumers must
be revisited; the typechecker is your first oracle.
- **Breaking** — stored events no longer parse under the new schema. Needs an upcaster
or a compat-mode migration (optional-then-drop).
- **Lossy-to-truth** — deletes or stops recording information from the event stream.
**One-way door.** A field nothing reads today still cannot be naively dropped:
future projections can never recover it.
The recoverability test: Models are *rebuildable* — replay the event stream through a
projection and you get them back, so model/projection/querier changes are cheap.
Events are *irreducible* — what was never recorded is gone forever. Spend your caution
budget on the event side.
## Exemplar events — good and bad
Good:
- `receipt_ingested { receipt_id, image_path, ingested_at }` — past-tense fact,
observed data only, carries identity and provenance.
- `recipe_extraction_failed { recipe_id, reason }` — failures are facts too; recording
them keeps the stream honest.
Bad (and why):
- `ingest_receipt` as an event — imperative; that is a command. Events state what
*happened*, commands request what *should happen*.
- `average_order_value_updated { avg }` — a derivation recorded as if observed. Derived
values must be outputs of a procedure with provenance, or live in a model rebuilt by
a projection — never masquerade as facts.
- `user_registered { email, password_hash }` — PII-class slots in an immutable stream
you can never delete from. Route sensitive data through commands and models.
- `order_placed` and `order_submitted` sharing most slots — the same fact at two
grains. Pick one grain per fact.
## Command per lifecycle step
| Step | You want to... | Reach for | Status |
|---|---|---|---|
| Onboard | Orient yourself / a fresh agent session | `dizzy onboard`, `dizzy docs` | shipped |
| Design | Author the feature-file | `dizzy docs authoring`, then `lint`, `simulate` | docs shipped; rest planned |
| Build | Scaffold schemas, generate types + packages | `dizzy generate definitions` → `static` → `libraries` | shipped (python-uv) |
| Change | Assess a feature-file edit | `diff`, `impact`, `compat` | planned |
| Migrate | Replace a model after a schema change | `rebuild <model>` | planned |
| Run | Observe / compare runtime vs. design | `trace`, `drift` | planned |
| Adopt | Wrap a legacy API as commands/events | `wrap` | planned |
| Deploy | Emit a deployment profile | `deploy` | planned |
The shipped path today (run in order, authoring between each step):
```
dizzy generate definitions <feat_file> <output_dir> # scaffold def/ + libconfig.yaml — then YOU author field detail
dizzy generate static <feat_file> <output_dir> # compile def/ → gen_def + gen_int type packages
dizzy generate libraries <feat_file> <output_dir> # per-runtime element packages — then YOU implement the stubs
```
For the full per-command reference and roadmap: `dizzy docs cli`.
For the authoring contract (what you write after each stage): `dizzy docs authoring`.
Good — I understand Dizzy's model now: two loops (Commands→Procedures→Events→Policies→Commands, and Events→Projections→Models→Queriers→Procedures) built around an immutable event stream and a feature-file. Let me check the current directory before building.

Now I'll build the visualization as a single self-contained HTML file. This is a substantial build — let me write it directly.

Good — the graph, queue, and arm all render and the arm is mid-motion (matches 3 samples in flight). One thing to fix: the loop-back policy→command arcs curve above y=0, which is outside the viewBox and may clip. Let me fix that and take another look after more time has passed.

Found it — a temporal-dead-zone bug: commandLoop() starts running (and calls wait() → speedFactor() → speedRange) before the const speedRange = ... declaration is reached later in the script. That's why nothing ever progressed. Let me move the control element declarations to the top.

I'll move the control-element lookups (playBtn, speedRange, etc.) up near the top utils section, right after $ is defined.

Now remove the now-duplicate declarations further down in section 8.

Now let's write a small Node CDP client to navigate, wait real wall-clock time, and screenshot — this will confirm whether the animation works under normal (non-virtual-time) conditions.

This confirms the page works correctly in real time — commands, events, and the arm animation are all flowing properly. The earlier "stuck" appearance was purely a --virtual-time-budget headless testing artifact (rAF never fired), not a bug in the page. Let's look at the real screenshot.
It's working well. Let's watch longer to confirm the full lifecycle (processing color changes, reaching output tray) completes correctly.

Good — it's not frozen, it's progressing normally (queue contents change each check). The earlier "stuck" numbers in test3 were coincidental steady-state values. Let me run longer to confirm samples actually complete.

Confirmed working end-to-end — samples complete and the pipeline reaches steady state. Let's view the final screenshot.
The pipeline works correctly end-to-end. Let me do one more check to confirm the sample dots render with correct colors as they move between stations.

Scenario: an arm picks a sample from one of 3 bins, carries it through Heater → Analyzer → Cooler, then places it in an output tray. Every step is driven by a real (if miniature) 8-node command/procedure/event/policy graph, matching Dizzy's dizzy onboard model:
collect_sample, transport_sample, process_sample, store_sample) handled 1:1 by 4 procedures, which drive the arm and emit 4 events.samples, arm_status); a combined query/querier node (matching the .feat.yaml convention of expressing q+Q as one entry) is called by process_sample_proc before it acts — the data loop (events → projections → models → queriers → procedures).The arm itself uses real 2-link analytic IK, not canned keyframes, with eased angle-tweened motion and an open/close gripper.
Bugs I hit and fixed during QA (verified via a headless-Chromium/CDP harness since I have no browser UI):
speedRange used before its const declaration ran) that silently froze the whole simulation — moved control lookups earlier.Confirmed working end-to-end in real time: events fire, samples change color per processing stage, and completions accumulate steadily.
Built a standalone HTML/JS robot-arm visualization of a Dizzy event-driven system in project-dizzy-viz/sonnet5/index.html; it's working end-to-end after fixing a few bugs found via headless testing. Next: open it in a real browser to eyeball the visuals yourself.
