Merge gitea/main into the Motion branch
Motion was written against a base five commits behind main, so the integration is the interesting part of this commit: - The migration is renumbered 0014 -> 0015. Main shipped 0014_piggy_conversations, and two migrations sharing an index is a journal that applies one of them. - The seed-idempotency gate keeps main's all-tables diff rather than the motion_templates counter this branch added; the general check subsumes the specific one. - Nav gains a Motion group alongside main's new Workspace group, and Piggy keeps the mark main gave it. - Stat keeps main's container-scaled figure, which already carries the min-w-0 this branch added for the same reason. - Piggy's page labels keep main's refusal wording for the four pages with no tool of their own, and gain the three Motion routes.

* This is the one defect in the harness swap that cost real money and produced
|
||||
* nothing at all. `createAgentSession` defaults `thinkingLevel` to `medium`,
|
||||
* which is tuned for a coding agent; asked "what is our utilisation?", the
|
||||
* default model spent 6,195 output tokens reasoning and returned an EMPTY
|
||||
* answer with `finish_reason: length`. Reasoning bills as output, so the turn
|
||||
* was billed in full for nothing. `low` was worse. The fix is two halves and
|
||||
* BOTH are needed:
|
||||
*
|
||||
* 1. `PIGGY_AGENT_THINKING` defaults to `off` (apps/piggy/src/config.ts:71).
|
||||
* 2. The default model carries a `thinkingLevelMap` mapping `off` to the
|
||||
* literal `"none"` (apps/piggy/src/agent/models.json:22-30).
|
||||
*
|
||||
* Half two is the half nobody would guess, and it is why this file exists. In
|
||||
* `@earendil-works/pi-ai@0.84.1`, `streamSimple` turns a thinking level of
|
||||
* `off` into `reasoningEffort: undefined`
|
||||
* (dist/api/openai-completions.js:473-474), and the request builder then reads:
|
||||
*
|
||||
* else if (!options?.reasoningEffort && model.reasoning && compat.supportsReasoningEffort) {
|
||||
* const offValue = model.thinkingLevelMap?.off;
|
||||
* if (typeof offValue === "string") { params.reasoning_effort = offValue; }
|
||||
* }
|
||||
* — dist/api/openai-completions.js:661-666
|
||||
*
|
||||
* So without a map, `off` OMITS `reasoning_effort` from the request entirely
|
||||
* and the endpoint's own default — thinking ON, verbosely — wins. With the map,
|
||||
* the request carries `reasoning_effort: "none"` and the same question answers
|
||||
* in 149 output tokens. Nothing about the omission is visible in TypeScript, in
|
||||
* the configuration, or in a passing test suite: the only symptom is a blank
|
||||
* reply and a bill.
|
||||
*
|
||||
* The behaviour is per-model, so the assertions below are anchored to whichever
|
||||
* model is the default rather than to nemotron by name. A future default that
|
||||
* needs its own mapping fails here rather than in production.

/**
|
||||
* What Piggy does when Prime Inference says "please retry shortly".
|
||||
*
|
||||
* The failure this file pins was measured on production on 2026-08-14, roughly
|
||||
* every other turn:
|
||||
*
|
||||
* [piggy] chat turn ended in an inference error: 429:
|
||||
* {"message":"Rate limit reached. Please retry shortly.",
|
||||
* "type":"rate_limit_exceeded","code":"rate_limited"}
|
||||
*
|
||||
* A `curl` a second later succeeded, so these were transient bursts and the
|
||||
* endpoint was telling us what to do about them. Nothing did.
|
||||
*
|
||||
* The endpoint cannot be asked to rate limit on demand, and a test that waited
|
||||
* for it to happen would be untrustworthy in exactly the conditions it exists
|
||||
* for, so every upstream here is a stub installed over `globalThis.fetch`. That
|
||||
* is a real seam and not a convenience: the OpenAI client the harness builds
|
||||
* resolves its fetch through `getDefaultFetch()` at construction, and it
|
||||
* constructs one per model call (openai@6.26.0 internal/shims.js:9-14), so a
|
||||
* stub installed before `prompt()` is the transport the harness genuinely uses.
|
||||
* Everything below therefore runs the real `createPiggySession`, the real
|
||||
* harness and the real OpenAI SDK against a fake endpoint — the retry is the
|
||||
* only thing under test, and none of it is mocked.

|

* `pig_get_idle_capacity` — the only tool that page offers — and said "3". The

|
||||
* length of the list it had been handed was the only count in front of it.
|
||||
*
|

* The system prompt already forbade that, naming this exact tool. So the guard
|
||||
* cannot be a prompt and cannot be a convention; it has to be a test that fails
|
||||
* when a result stops carrying its own denominator. Three things are pinned
|
||||
* here and nothing else:
|
||||
*
|
||||
* 1. every result carrying a count or a collection carries a `scope`;
|
||||
* 2. a filtered count is never the only count in its own result;
|
||||
* 3. the threshold that produced a filtered count is named in the payload,

||||
* because three surfaces of this product have quoted three different idle
|
||||
* figures and the only way to reconcile them is to know which is which.
|

/**

* What the chat server does about a turn the endpoint stops answering.
|

*
|
||||
* The failure this file pins was observed in production: `POST
|
||||
* /chat/completions` began hanging while `GET /models` still answered in 0.2s,
|
||||
* so the stream emitted its `meta` frame and then nothing at all, for ever, and
|
||||
* the transcript span until the browser gave up. A direct `fetch` from Node ran
|
||||
* past 180 seconds without settling. The harness owns the HTTP call now and sets
|
||||
* no deadline on it, so the guard has to live where PIG can see the turn: the
|
||||
* session's event stream.
|
||||
*
|
||||
* Every session here is a double, and deliberately so — the endpoint that
|
||||
* caused this cannot be asked to stall on demand, and a test that depended on it
|
||||
* would be untrustworthy in exactly the conditions it exists for. A double that
|
||||
* never settles is the same silence, and it is deterministic besides.

|

|

* The snippet case is the second. A custom tool without `promptSnippet` is
