Owner decision 2026-09-22: 'it doesn't make sense to have any default
model configured anywhere; the application is bring your own keys.'
config.ts: MODELS deleted; ModelRole becomes an explicit 9-role union;
DEFAULT_THINKING_ORDER (medium, low, high, minimal, xhigh, max) bakes
the unset-level default — first entry the model supports; explicitly
set levels keep pi's native nearest-clamp.
core/settings-resolution: the factory layer dissolves — the chain is
role override → slot → NOTHING. resolveSettings(record) takes no
factory. Empty chains resolve to null/undefined; a thinkingLevel-only
slot is inert (stored, never run). resolveConversationSpec: chat.model
override over the strong slot, null when both empty. resolveRoleSpec
spans all nine roles for the job/extraction engines.
Refusal envelope (core/settings.ts): modelsNotConfigured(missing) —
{error, code: 'models_not_configured', missing: [slot tiers]} +
ModelsNotConfiguredError with .envelope. Per-need gates, each honest:
- chat-handler: universal turn gate (new + continuing turns) returns
503 before beginTurn — no liveness, no write-ahead persist, no graph
trigger before the gate fires.
- runner.runJob: unresolvable engine lands the job as error with the
envelope wording; no phantom loop, no result steer.
- extraction: refuseIfStagesUnconfigured throws before any stage
(turn-service info-skips so coverage retries next turn; the import
route surfaces per-file code+missing); labeler-less runs skip
cluster naming with a console line and still merge.
Write side: slot entries must carry a model — level-only slot writes
are 400s (absent slot key = clear). piEngineForSpec resolves unset
thinking levels via DEFAULT_THINKING_ORDER; piEngineFor now throws
honestly; thinkingLevelFor/modelIdFor deleted; teacher-agent, pi-run,
visual-maker, pdf-reader all read engine.level.
model-catalog: defaults/slots/rolePins null when the chain is empty
(contracts nullable) — no phantom ids in payloads. Stores drop
MODEL_PINS entirely.
Tests: pin-leaners converted to explicit injection (per-chat model
pins on scripted chats — exactly what the setup flow writes; faux
engines for agent-construction tests). New coverage: the 503 gate
envelope, the runner refusal, the extraction refusal + labeler skip.
Gates: typecheck, lint, 815/815, build.

/**
|
|
* Job infrastructure tests — deterministic, zero network:
|
|
*
|
|
* 1. job store CRUD (create → get → update → list → dedup by toolCallId)
|
|
* 2. steer helpers (pure, contracts.ts): buildSubagentSteer shape per kind,
|
|
* isSubagentFailure, steerDelivered
|
|
* 3. dispatch (async protocol §2): drive handleChatRequest with a scripted
|
|
* mock teacher that emits a research tool call → the tool part resolves
|
|
* IMMEDIATELY with the fire-and-forget ack (the teacher's turn
|
|
* CONTINUES — no turn break at the call), a job record exists, and the
|
|
* test runner (fake deliver) produces the steer
|
|
* 4. runner completion: a fake researcher model (web_search call → final
|
|
* text brief, globalThis.fetch stubbed) → the job stores the result,
|
|
* the steer carries the brief + sources, the fake deliver flips the
|
|
* job done
|
|
* 5. runner failure: a model that throws → the failure steer still fires
|
|
* (the teacher learns the outcome) and the job lands error
|
|
* 6. the wake pipeline (src/server/jobs.ts): server-side steer delivery —
|
|
* happy path (fires the injected turn runner, flips the job), pending-
|
|
* quiz deferral, 409 retry, idempotent redelivery
|
|
*
|
|
* Cleanup follows tests/chat-flow.test.ts: created chat/job files removed in
|
|
* finally blocks / the after() hook.
