WHAT THIS IS
A working playground for the Cloudflare developer platform, dressed as the
operations console of Hewland-Yutani's HWTT mining division. Everything on
screen is real: the rigs are Durable Objects ticking on alarms, the archive
is a genuine retrieval system over 68 documents, and the X-ray panel shows
the actual products firing on each request. Nothing is mocked.
READING THE X-RAY PANEL
The right-hand panel is the point of the whole thing — it shows what the platform did, not just what the app returned.
| REQUESTS | Every request grouped by id, with its hops as a waterfall. Bar length is real duration, so you can see the model call dominate while D1 finishes in under a millisecond. Click any hop for the exact SQL, R2 key, model or token count — plus what that product is and why it is here. |
| FLOW | An architecture diagram built from hops actually observed, never hand-drawn, so it cannot drift from the code. Line weight is how often a path has been taken; a token rides the curve as each request runs. |
| COST | Units consumed this session priced at published rates. Everything sits inside the included allowance — the point is the shape of the pricing model. |
| RAW LOG | The unstructured feed, newest first. |
Autonomous rig ticks are tagged as background and hidden by default, so your own actions are not buried. Toggle "show background" to see them.
THE SCENES
PRODUCTS AND WHERE THEY ARE USED
THINGS WORTH KNOWING
Grounding. The archive refuses rather than guesses. If retrieval returns
nothing, or the best match is too weak, or a draft answer cites a document that
was never retrieved, the answer is withheld and you get told what is missing and
which department would hold it. The agent is held to the same standard: it may
not overrule the archive's verdict, and any figure it states must have come back
from a tool in that session.
Deliberate substitutions. Waiting Room needs a Business plan, so the
Airlock models the same problem on a Durable Object. Queues and Workers for
Platforms are parked for v1.
Costs. The whole thing runs on the $5/month Workers Paid plan. AI Search
is free during beta, email to verified destinations is free, and Pages is free.
