feat(T2b): sources v0 — read tool + pdf-reader sub-agent
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. |

feat: graph context injection — the session's prior knowledge, steered in at session start (vision-context-injection.md)
One shot per chat, fired at the first turn's onFinish: the session's topic (its only typed message) is embedded as an EmbeddingGemma retrieval query; the semantically closest graph propositions are selected under the session's token budget (pure budget, no similarity threshold — the decided doctrine) and delivered as a marker-only steer through the wake pipeline, queuing behind pending questions like every sub-agent result. - contracts: ChatSettings.graphContextTokens (default 1024, max 4096, step 128, 0 = off); GraphContextData + graphContextText; the graph-context JobKind + buildGraphContextSteer (id steer_ctx_<chatId>) - core/graph-context.ts: brute-force cosine top-K, greedy chars/4 fill under budget, most-recent UnderstandingLevel fold, count cap 64, parse-don't-cast at the marker seam - server: embedQuery (role-asymmetric query format, same warm singleton — vector-space parity by construction); the runner (startGraphContext- Injection one-shot gates; runGraphContextJob validates ledger parity); wake branches (chatIdOf/jobIdOf, finalizeJob done, recoverStaleJobs re-deliver or contextRespawn); abortJob kills context jobs SILENTLY (nothing was promised in the lesson); turn-service trigger seam - adapter: data-graph-context flattens to the canonical block (malformed parts have no model face) - UI: the budget slider (home dock + /chat/new draft, the session-data strip); the quiet SystemLine "~537 · 10 propositions"; dock kind "Knowledge context"; model-picker PUT now spreads settings (a model pick can no longer clear the sibling override) Live-smoked end to end on the real embedder + real GLM: seeded ledger (10 propositions), session on "modal logic: possible worlds and the necessity box" — job in the dock, queued behind the prober's question, delivered on the answer, SystemLine in the transcript, wake turn reads the block and continues the probe. Gates: tsc, lint, 459/459, build. |

feat: custom message types for system turns — wake and verdict messages
The custom-message scheme (user-decided 2026-09-12): system-authored
user-role messages are NOT human messages — they carry marker data parts
only, the adapter owns their model-facing wording, and the UI renders
them under control. Nothing fake is ever persisted as human speech.
The inventory (all migrated):
- probe→teacher handoff wake: was a text-bearing user message rendering
as a fake user bubble; now data-probe-handoff marker-only — the
adapter flattens it to HANDOFF_TEXT (core/contracts/chat.ts), the UI
renders a quiet 'Preparing your plan…' system line.
- plan accept/decline: was boilerplate text ('The plan is accepted…',
'I'd like the plan revised…') masquerading as learner speech — the
decline wasn't even marked; now data-verdict {accepted, at} on its own
message, adapter flattens to verdictText(), UI renders the quiet
verdict marker ('✓ Plan accepted' / '↻ Plan revision requested').
sendVerdict sends TWO REAL MESSAGES when the learner typed a note
(the note as a genuine user message, then the verdict) in ONE turn
via setMessages + sendMessage() — no 409 dance, no double teacher turn.
- sub-agent steers: the abort steer gains its data-subagent-aborted
marker part; the UI keys steer rendering off PARTS (artifact/aborted),
not metadata — metadata stays as pump mechanics only.
- record-adapter: systemTextOf() flattens marker-only messages; steers
keep their text (payload — briefs are content, not boilerplate).
phases.ts: plan→teach advances on data-verdict{accepted:true} only;
learner text alone can never sanction teaching (pinned). data-plan-
accepted retired, no back-compat (user-decided: wiped-data doctrine).
Pinned: record-adapter.test.ts (verdict/handoff flattening, note+verdict
order, steer payload kept, UI-only parts skipped), phases.test.ts
(verdict marker semantics, out-of-order, text-never-fakes), jobs.test.ts
(abort marker part), demos.test.tsx (badge renders off the part, not
metadata).
Live GLM smoke (disposable driver, deleted): probe→conclude→wake→plan→
decline-with-note (revised, still plan)→accept-with-note (teach) — ALL
CHECKS PASS, including marker-only handoff/verdict on the wire and zero
fake human speech in the transcript.
Gates: tsc, lint, build, 335/335.

Swap the server engine to pi-ai/pi-agent-core (Band B+C of docs/pi-engine-swap.md)
The Vercel AI SDK survives only as Band D (useChat client + UIMessage
record types); @openrouter/ai-sdk-provider is uninstalled.
- src/agent/models.ts: PiEngine {model, streamFn} via createModels +
openrouterProvider subpath; thinkingLevelFor maps config effort none->off
- src/agent/lh-tool.ts: neutral LhTool (zod authoring, optional execute,
clientQuestion flag); toPiTool converts via z.toJSONSchema and re-runs
zod inside execute so refinements ride the error-result retry path
- src/server/pi/record-adapter.ts: UIMessage records -> pi Messages
(dangling tool calls get synthesized interrupted results)
- src/server/pi/ui-stream.ts: SSE bridge emitting AI-SDK-shaped chunks so
the useChat client parses unchanged (continuation id rule, question
tools never emit output, tool-input-error for bad authoring)
- teacher-agent.ts: stateless per-turn pi Agents; shouldStopAfterTurn
stops only when every question-tool call resolved cleanly (errors retry)
- chat-handler.ts: buildAgent(outgoing) factory seam (stateless doctrine);
assertValidUiMessages owns the retired SDK validation gate
- sub-agents via shared runSubagent (pi-run.ts); extraction stages stop
after a clean submit; visual-maker keeps its hand-rolled loop over
direct streamSimple calls; aborted model calls bill no usage
- tests: all model seams ported to pi-ai faux provider (scripted
FauxResponseSteps, agent factories); handleChatRequest second param
is now an agent factory
Gates: tsc, lint, build, 305/305. Live GLM smoke (disposable driver,
deleted): prober streaming + persistence, question seam, turn-2
continuation same message id, per-turn real token usage - ALL PASS.
Data wiped at the pivot (chats/graph/jobs, .gitkeeps kept).

feat: probe/teach agent split — explicit phase markers, position-only plan map
Diagnosis (2026-09-11 user testing, minimal-effort GLM): sessions stuck on 'plan' forever. Two causes: (1) the three-phase view read the stored tree's currentNodeId, which nothing ever writes post author-once (2026-09-03) — a structural dead seam; (2) the teacher stochastically left quiz.nodeId untagged, and done-by-quiz-result semantics would have falsely completed nodes anyway. The redesign (docs/probe-teach-split.md) abolishes derived occupancy in favor of explicit events: - Two agents over one transcript: createProberAgent (quiz without a nodeId field, ask, probe_done) and createTeacherAgent (full toolset, plan_init onward). The chat-handler construction branch keys on a probe_done part in the transcript. MODELS.prober added. - probe_done: server-side seam tool — carries the learner assessment (strands + free-form edge read), refuses while a question is open or the probe is already concluded, and queues a handoff steer through the generalized wake pipeline (steers now dedupe by id, not jobId; job finalization only for job steers). The teacher auto-wakes and authors the plan; the learner sees the assessment via the probe-done card. - phases: probe ends at a concluded probe_done, plan ends at a successful plan_init — strictly sequential, no skipping, no legacy compatibility (data wiped at the pivot per doctrine). - Plan map = position, not completion: derivePlanStatuses reads only tagged quiz CALLS (state/outcome feed nothing); current = latest tagged node with consecutive duplicates collapsed, visited = earlier distinct stays (a revisit stays in both — current wins at render). PlanTree is structure-only; currentNodeId/doneNodeIds and the dead mutation helpers are gone. No fallback current. - Prompts split per agent (prompts/prober/, prompts/teacher/ over the trimmed shared base); graph-context injection removed entirely (shelved, docs/probe-teach-split.md §5); knowledge-graph context no longer reaches either agent. - Plan blocks are full-only snapshots at plan_init (neighborhood machinery retired; the persistent DAG window is the future UI wave); usage capture unchanged. Gates: tsc clean, 294/294 tests (phases/plan-tree/plan-blocks/question- tools rewritten to the new semantics; probe-done + handoff-wake tests added), lint, build. Live GLM smoke PASS: prober concluded with an honest assessment, teacher auto-woke, authored a 10-node plan with the block attached, then tagged checks on slope-instinct → secant derived current/ visited exactly as designed; grading honest both ways (driver off-by-one proved a wrong answer grades false). |

feat: abort sub-agent jobs (real kill) + runner usage capture into JobRecord.usage
Wave 4 (agent-side observability + control), reconciled with the dock contract (master relay 2026-09): - abortJob in src/server/jobs.ts, exported through the server barrel for POST /api/activity/abort (master's thin route): fires the job's AbortController (real kill — the in-flight model call aborts, not just the next loop check), drops any queued result steer, flips the record to error "Aborted by learner" + activity "aborted" synchronously, and queues a one-line abort steer (buildAbortSteer) through the same wake pipeline so the teacher's promise doesn't hang in the lesson. Shares the result steer's deterministic id space, so abort + racing result can never both deliver (steerDelivered dedupe). - Abort registry (src/agent/subagents/aborts.ts) on globalThis, mirroring the wake pipeline's module-state pattern; runner registers/unregisters per run, so the route's module instance sees the loop's controller. - Runner usage capture: LoopContext (abortSignal + onUsage) threads into all three kind loops; per-step usage folds via accumulateJobUsage into JobRecord.usage (model from config MODELS, absent-never-zero), flushed in runJob's finally so an aborted job's money record survives the kill. - Contracts: JobUsage token fields optional + lastStep (most recent call's accounting, for the dock's per-blob context line vs CONTEXT_LIMITS); SubagentResultMeta.aborted; AbortSteerMessage; buildAbortSteer; SteerMessage union generalized. - demo-builder/visual-maker accept abortSignal + onUsage (visual folds generateText usage per iteration). - stillRunning/finishJob/jobContext guards: an aborted job is never overwritten by the runner (terminal no matter what the wake does); failJob and the pump's finalizeJob keep the flip. - UI: abort steer renders a quiet aborted chip (job-aborted-badge). - Prompt 20-jobs.md: one line about aborted jobs. Tests: accumulateJobUsage folds (undefined-preservation, lastStep), runner usage capture, real-kill abort (sync flip, silent unwind, abort steer wakes), usage-so-far survives the kill, aborting a delivering job drops the queued result steer, outcome reasons, abort-chip render. 330/330, typecheck/lint/build green. |

Observability contracts: usage accounting, plan blocks, price table (Phase 0)
The 2026-09 observability wave's type-level foundation, landed before the streams so nothing renders against guessed shapes: - contracts/chat.ts: CallUsage + TurnUsage (per-model-call token accounting, one entry per teacher/wake turn keyed by messageId) and ChatRecord.turns — a DELIBERATELY parallel append-only usage log, not per-message metadata: the client re-POSTs its message list every turn and its copies never carry server-stamped fields, so anything inside messages gets clobbered by the next persist (the wave-3 merge-rule lesson). - contracts/chat.ts: PlanBlockData — the persisted data-plan-block part (full DAG on plan_init, one-level neighborhood on plan updates, snapshot semantics so history renders what was true then). - contracts/jobs.ts: JobUsage + JobRecord.usage — a sub-agent run's accumulated accounting, written by the runner. - core/ports.ts + store/chats.ts: ChatStore.appendTurnUsage — idempotent per messageId (abort replays / wake retries append once); listChats no longer leaks turns into the list payload. - core/prices.ts: PRICES + CONTEXT_LIMITS (generated from OpenRouter's published pricing via scripts/sync-pricing.ts) + pure folds: callCost, turnCost, sessionCost, contextWindow, jobCost. Unknown model or absent fields render as absent, never zero. - server/observability.ts: barrel-approved surface for the transport layer (fixes the import-law violation in the graph status route that slipped through the wave-3 merge verification). Capture wiring (agent onStepFinish -> persist seam, plan-block emission) lands next as master seam work; the streams start against these shapes. |

fix: steer-delivery starvation — continuation coalescing (claimSteers)
The bug (seen live): a teacher that ends every turn with a new pending quiz keeps the wake pipeline's idle gates permanently closed — the steer sits in 'delivering result' forever while the learner answers check after check. - claimSteers (server/jobs.ts): the chat-handler claims every queued, undelivered steer the instant a client turn wins the turn registry, and appends it after the learner's answer — conversion-safe, the answered quiz carries its output. Every answer flushes pending steers immediately. - The pump keeps its post-idle duplicate-guard (re-check steerDelivered before firing), so a claim racing the pump converges to exactly one delivery either way. - The stale-job sweep now skips chats with a turn in flight (a healthy but slow wake no longer gets falsely re-queued as 'recovering'). - Out-of-lane surgical touch (flagged for master review): the 3-line handleChatRequest seam (claim after beginTurn, persist+stream 'outgoing'). - Verified live end-to-end on the stuck session: answering the pending quiz fired the steer + wake turn within a second; job flipped done/delivered. |

Split contracts.ts by domain: plan / graph / chat / jobs
Purely mechanical: src/core/contracts/{plan,graph,chat,jobs}.ts carry the
sections verbatim (graph = nodes + ledgers + extraction findings; jobs =
the async ack-and-steer protocol + tool results + demo bridge), and
contracts.ts becomes a re-exporting barrel so every existing import path
(@/src/core and ./contracts.ts) is unchanged.
Wave-2 lane ownership follows the split: the graph stream owns
contracts/graph.ts, the teacher stream owns contracts/jobs.ts — same-file
contract collisions between streams are structurally impossible now;
cross-domain schema changes go through master.
