feat(T2a): tool-toggle seam + phase-based question principles
Part 1 — tool availability (the settings seam, machinery generic): - core/pending.ts: TOGGLEABLE_TOOLS (today: research, demo, visual — the model-facing tool names), EnabledTools = the JSON-native seam shape Partial<Record<string, boolean>> (absent key = enabled, so old records behave exactly as today), filterEnabledTools shared helper. quiz/ask_user_question are always-on FOR NOW (user-decided); the filtering is generic so future toggleables (question-tool variants, the read tool, …) need no factory change. - createProberTools/createTeacherTools take enabled?: EnabledTools; the composition root (chat-handler, Platform's lane this wave) passes the resolved settings through. probe_done is re-added after the filter — always-on by construction (it ends the phase; a prober that can never conclude is a lockout). - Prompts stay STATIC under toggles this wave (user-decided); standing principle recorded: tools ship self-contained usage guidance in their descriptions; system prompts reference only always-on tools. Part 2 — phase-based question-writing principles (user-locked wording, drafted with the user over three iterations): - NEW teacher/21-question-principles.md (composes after 20-teaching): answerable-by-reasoning-from-the-session (the fairness rule that filters unanswerable questions without forbidding visible answers), never-just-reciting-your-words-back, PREFER problems that apply the knowledge (preference, not hard rule — honest recall is the fallback, not the habit), catch-confusion-early-and-nameable (wrong options as real misconceptions), answer-is-signal-not-verdict. - prober/10-probe-doctrine.md: 'no rush' retired; quick-measurement directive in — every question moves an edge (bracket, narrow, or characterize); a bracketed strand is done. Tests: TOGGLEABLE_TOOLS pin, prober/teacher filtering (absent = full, false drops exactly that tool, probe_done survives), prompt pins (the principles compose verbatim into the teacher prompt, the no-rush framing is gone from the prober). 547/547, typecheck/lint/build green. |

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). |

Author-once plan protocol: single mermaid plan_init + derived statuses + live quiz nodeId validation
- plan_init is now the ONLY plan tool: a mermaid 'graph TD' block parsed by a constrained-subset parser (mermaid-plan.ts) with line-precise errors; the seven mutation/tracking tools are gone by design (2026-09-03 design pass). - Re-call plan_init = sanctioned wholesale rewrite; slugs are permanent. - derivePlanStatuses (contracts/plan.ts): done = passed check tagged with a quiz nodeId; current = open check's node else first topo-ready node — the tracking the teacher no longer declares by hand. - questionToolsFor(ctx) (tools.ts): the quiz schema chains a dynamic plan- nodeId validation against the LIVE record — an invalid nodeId is rejected at the call boundary and the teacher retries mid-turn, before any UI. Static questionTools stay validator-less for the default path. - Prompts rewritten for mermaid authoring + derived position. - Out-of-lane surgical touches (flagged for master review): src/core/question-core.ts (quizInputObject export + nodeId description), src/core/contracts/plan.ts (derivePlanStatuses + doc). |
