Learner source files, on the teacher's own terms (nothing auto-injects): - read tool (src/agent/tools/read.ts): pi-read port — path/offset/limit, 2000-line/50KB truncation with use-offset continuation notices, image files (jpg/png/gif/webp/bmp) returned as native image content parts (new LhToolImageResult escape hatch in lh-tool.ts). Always-on in both the prober and teacher registries (user-decided 2026-09). - pdf-reader sub-agent (JobKind 'pdf', toggleable, ack-and-steer): triage via pdf_info (pdfjs text layer: per-page text/image/math-density), targeted pdf_extract, regex pdf_search (hits count as consultation), and pdf_render — pages painted by pdfjs onto a canvas shim in headless Chrome (the pdfium viewer doesn't paint headless), screenshot fed back image-in-the-loop (visual-maker idiom, providerSafePng applied). The unread-finish gate bounces a zero-consultation brief once. Teacher gets a text brief with page citations only; renders never leave the loop. - MODELS.pdfReader = qwen/qwen3.8-flash (user override 2026-09-19: the look-at-renders workload wants the vision-proven model; catalog listed glm-5.3-flash as image-capable but qwen is the known-good daily driver). - UI: PdfCompleteBadge + PdfBriefCard (steer-card, job-card), dispatch card + activity-dock kind entries (type-forced, flagged for UI review). - Prompts: 'Learner source files' section in teacher/30-jobs.md; read line in prober/10-probe-doctrine.md. Doctrine rides tool descriptions per the self-contained-tools principle.

/**
|
|
* 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.
