Rebuild Piggy's interface, and give the demo book a business to describe
Piggy answered in raw markdown, threw away every tool result it streamed, and fought the reader's scroll on every token. The three surfaces that made it worth having — what it read, how it reasoned, what it cost — were all on the wire and none of them reached the screen. The transcript is now composed of five parts under components/piggy: answers render through streamdown, the container sticks to the bottom without pinning the reader there, tool steps say what they read and link to the record, and each turn carries its model and token count. Three lifecycle bugs went with them: Stop left a permanent spinner, a truncated stream was indistinguishable from thinking, and a failed send destroyed the message it failed to send. Underneath, the inference path grew timeouts, jittered retries on 429 and 5xx, tolerance of the malformed frames a 30B model emits, and an agent_runs row per turn so chat spend is observable. The system prompt now states that a field ending in Cents is cents — without it nemotron renders costPerGpuHourCents: 189 as "$189 per GPU-hour", which is a 100x error on the most scrutinised number in the room. The demo book was arithmetically incoherent: every deal's value contradicted its own allocation revenue by up to 3.6x, nothing had ever closed, no customer had any paper, and the marketplace was empty. Deal value is now derived from the allocation, the book clears 5.3% across five blocks with one deliberately underwater, and the renewal, compliance and agent-provenance machinery finally has rows to act on. A --clear that deleted every obligation, SLA term and capacity request in the database regardless of origin is scoped to the demo's own ids. Around that: accounts have a detail page, ⌘K searches the book, Settings can mint the API keys it always claimed to, and deploy.sh actually ships the agent instead of silently skipping its compose profile.

|

* Four, chosen against a fixed budget: every entry here is in the prompt of
|
||||
* every message and is another candidate for a small model to pick wrongly.
|
||||
*
|
||||
* `pig_search_records` and `pig_get_record_by_id` are the pair that lifts the
|
||||
* one-question ceiling — find a row by name, then open it. `readFocusedRecord`
|
||||
* does the opening, so a record fetched by id is shaped exactly like the record
|
||||
* the panel was opened from and the model has one shape to learn, not two.
|
||||
*
|
||||
* `pig_list_renewals` exists because the renewal deadline is expiry minus
|
||||
* notice days, which nothing in a record payload states outright: given the raw
|
||||
* contract a model has to do date arithmetic it is bad at, and a notice window
|
||||
* that quietly opened last week is the most expensive thing in this book to
|
||||
* miss. The calendar tool does surface renewal notices, but only on /calendar,
|
||||
* mixed into thirteen other kinds, and without the contract ids.
|
||||
*
|
||||
* `pig_list_inventory` reads what providers are currently offering. Nothing
|
||||
* else can see that table at all, and "what would this cost us to buy today"
|
||||
* is the supply half of every pricing conversation.
|
||||
*
|
||||
* Declined, deliberately:
|
||||
*
|
||||
* - A commitment-comparison tool. `pig_search_records` plus two
|
||||
* `pig_get_record_by_id` calls already answer it inside the four-turn budget,
|
||||
* and `pig_get_margin_summary` already ranks live blocks by margin. A fifth
|
||||
* tool would be a fifth wrong choice for a question two calls cover.
|
||||
* - Anything over `activities`. There are 185 of them, they are prose, and a
|
||||
* bounded slice of somebody's notes is the fastest way to spend a 1024-token
|
||||
* answer on transcription. The lifecycle tool already carries the one
|
||||
* activity fact that changes a decision — when the account last moved.
|
||||
* - Contacts in the search index. A person is not a commercial record, the
|
||||
* account read already returns its contacts, and every extra searched table
|
||||
* dilutes the twelve result slots the model actually reads.

|

- A supply deal buys a block of GPU capacity from a supplier: a fixed number of GPU-hours at a cost per GPU-hour, over a fixed term. The block is a commitment, and it is paid for whether or not it sells.
|
||||
- A demand deal sells hours out of those blocks. Each sale is an allocation against one commitment.
|
||||
- Utilisation is allocated hours over committed hours. Idle hours are committed hours nobody has bought — already paid for, and unsellable once the term ends.
|
||||
- Gross margin is revenue minus the FULL cost of the commitment, not the cost of the hours that sold. Never recompute it against sold hours alone: that hides the loss the idle hours have already incurred, which is the thing this system exists to show.
|
||||
- Break-even price is what the REMAINING unsold hours must fetch per GPU-hour to cover what is still uncovered on the block. It falls as the block sells, and it is the number a seller wants mid-term.
|
||||
- A break-even of 0 means the block is already in profit and any further sale is upside. A null break-even means the block is fully allocated, so there is nothing left to price.
|
||||
- Margin per GPU-hour is blended across the hours that sold. It is not the price of the next hour, and it is not a quote.
|
||||
- A commitment near expiry at low utilisation is the urgent case, however healthy the book looks in total.

* only way to see the chat UI move was to spend the credit. This speaks the
|

* trailing `usage` chunk — so the whole loop, including a real tool round trip,
|
||||
* runs offline and deterministically.
|

*
|
||||
* It is a development tool. It is never imported by the worker or the chat
|
||||
* server; it is started on its own with `pnpm -F @pig/piggy run dev:mock`.
|
||||
*
|
||||
* Steering it: a user message containing one of these directives makes the mock
|
||||
* take a specific branch, so the failure states of the UI can be seen on demand
|
||||
* rather than only when production breaks.

||||
*
|
||||
* /mock error — respond 500, the upstream-failure path

* /mock badtool — emit a tool call with unparseable JSON arguments
|
