**The async sub-agent protocol (ack-and-steer).** `research` / `demo` / `visual` are server-executed tools: the call resolves immediately mid-turn with a fire-and-forget ack and the teacher keeps teaching; a background runner works in parallel (the client polls `/api/activity` and `/api/jobs`). On completion the runner builds a **steer message** — a user-role `UIMessage` whose text part is the model-facing result and whose `data-subagent-artifact` part carries the full result for the client — and the **wake pipeline** delivers it: a per-chat serialized queue waits for the turn to end and no question to be pending, then fires a server-side teacher turn that weaves the result into the lesson. Delivery is exactly-once (deterministic steer ids, delivered-flag checks at every claim point); stalled jobs are recovered on read; aborted jobs deliver an abort steer. The client adopts the wake turn through the same `turnInFlight` machinery as returning mid-stream (busy shimmer, composer gate) and renders steers as artifacts — never a bubble. Sub-agents **verify, never one-shot**: the demo-builder headlessly executes its HTML in system Chrome before delivery; the visual-maker renders each SVG and looks at it (vision-capable model — the `vision` slot in settings).
-**The knowledge graph (two channels, one writer).** The write channel: the extraction pipeline — extractor (LLM, tree-blind: sees only the transcript view — propositions as true statements, `follows`/`supports` edges, retroactive quiz attribution, one-word understanding observations) → auditor (LLM: sees findings + the current graph; drops anything without verbatim evidence, stamps each survivor with an identity verdict — link to an existing node or create) → merger (`mergeFindings`, deterministic: applies the verdicts, link-appends phrasings/provenance, rebuilds quiz events from the transcript's tool parts, dedupes, checkpoints coverage) → layout settle. Triggered when a chat's **uncovered tokens** (message-view fingerprints, `coverage.jsonl`) cross `graph.extractionChunkTokens` (a settings knob, default 4096, floor 500 — read fresh per turn); failure checkpoints nothing, the next trigger re-runs. The same pipeline serves the **notes front door** (`POST /api/graph/import`: any `*.md`/`*.txt` becomes a source; re-imports are idempotent by path hash). The read channel: `GET /api/graph` derives the snapshot from the ledgers — a pure read; the home view is a hand-rolled Canvas 2D renderer (one rAF loop, dirty-flag idle, d3-zoom camera, zoom-gated labels, cluster hulls) over a d3-force layout, with server-persisted render settings and drag-committed positions. Clusters are **birth-session groupings**: a node joins the cluster of the session that birthed it (a chat, or an imported notes file as a file-kind session), derived at read — no embedding pass, no naming pass. The teacher reaches the graph on its own terms through the gated prober tools (`list_sessions` / `list_propositions`, the `agent.graphTools` setting) — there is no automatic context injection.

-**Tree-blind and post-hoc** (vision §1): the extractor reads ONLY the transcript — never the session's plan tree — and proposes free-form propositions (true statements; a misconception is stated as its true correction), `follows`/`supports` edges, per-proposition understanding observations (a closed one-word scale), and message-granular provenance. Every node is an objective, world-facing fact; the learner's relationship to it lives entirely in the event ledger.
+**Raw reasoning chains only** (2026-09-27 cleanup): the extractor reads ONLY the session — the whole thing, rendered as readable markdown by the shared engine (`core/session-markdown.ts`; the same renderer will serve future user-facing session export) — and proposes free-form propositions (true statements; a misconception is stated as its true correction) and `follows`/`supports` edges with verbatim evidence. Every node is an objective, world-facing fact. No quiz outcomes, no understanding assessments — the events ledger and `UnderstandingLevel` are deleted; the learner's relationship to a proposition becomes practice-module territory (assessment records, later).
-**Division of trust** (the pipeline's core rule): the LLM stages supply only judgment — *what was learned*, *what follows/supports what*, *which proposition each quiz tested*, and the auditor's *identity* verdict (whether a proposition IS an existing node). Everything the model could silently mis-copy — event kinds (`correct`/`miss`/`dont-know`), timestamps, idempotency refs, notes, provenance points — is rebuilt deterministically by the merger from the transcript's tool parts. The extractor files verbatim evidence quotes; the auditor drops anything unbacked and logs every drop. Conservative throughout: duplicates over wrong merges, drop over invent.
+**Division of trust** (the pipeline's core rule): the extractor is fully trusted and is the only stage that ever sees the source. The auditor never sees the transcript — it receives the findings JSON alone and explores the existing graph through read-only tools (`find`, `list_sessions`, `list_propositions` — statement text included, no timestamps) to reach identity verdicts: `linkTo` an existing node or let the merger create one. Equivalence bias (owner ruling 2026-09-27): paraphrases, rewordings, and compressions of the same claim MERGE; only genuinely distinct propositions stay apart. The auditor may also draw bridging edges — typed `follows`/`supports` connections between existing graph nodes and the batch's propositions (the auditor is the asserter: chat-scoped provenance, no message anchor). The deterministic merger validates and appends: linkTo resolution, dedupe by `(from, to, type)`, coverage checkpoints. There is no drop channel — nothing rejects the extractor's output.
-**Coverage, not quiz-counting** (supersedes the v1 every-N-quiz-answers trigger): each message's *view* (the same lines the extractor sees) is hashed into a per-chat fingerprint ledger (`coverage.jsonl`); "covered" means exactly "what the model saw." Uncovered = fingerprint diff, never dual-tracked; runs are greedy token-budgeted batches (`graph.extractionChunkTokens` — a settings knob, default 4096, floor 500, read fresh each turn) of the oldest uncovered messages — quiz-less sessions extract too. A coarse `sessions.jsonl` checkpoint still marks each merged run. The trigger seam (`turn-service.ts`) is trigger-agnostic from the pipeline's side: when a better mechanism lands (session end, idle, explicit flush), only the seam changes. Single-flight per source; the run registry powers the coverage UI and true abort.
+**Coverage, not quiz-counting** (supersedes the v1 every-N-quiz-answers trigger): each message's *view* (the compact line format `core/coverage.ts` has always hashed) is hashed into a per-chat fingerprint ledger (`coverage.jsonl`); "covered" means exactly "a run committed on this content." The prompt view is the richer markdown document — a deliberate 2026-09-27 split: re-formatting presentation never re-opens covered history.

**Two front doors, one pipeline**: chat transcripts (quiz-triggered) and raw personal notes (`POST /api/graph/import` — each file becomes a `NotesSource` playing the `chatId` role, deterministic id from the path hash).

+**The read channel is pure derivation.** `GET /api/graph` reads the ledgers (`graphSnapshot`: merged nodes/edges, birth-session clusters, positions) — the home view never triggers a write.

-**The teacher probes, nothing is injected** (supersedes the semantic-injection experiment, killed 2026-09-23): the teacher reaches the graph on its own terms through two read-only prober tools — `list_sessions` (birth sessions, the learner's files) and `list_propositions` (a session's extracted statements) — gated by the `agent.graphTools` setting (composing with `graph.enabled`). No topic embedding, no top-K selection, no session-start steer; the agent decides what to look at, and the graph never writes into a lesson unbidden.

-FAITHFULNESS — verify every candidate against the source text:
-- PROPOSITIONS: every evidence quote must appear (near-)verbatim in the transcript view, and the statement
- must be a faithful reading of it. The node theory applies: a statement must be a TRUE, self-contained,
- world-facing fact — reword learner- or session-relative statements ("the learner understands X" → "X"), state
- misconceptions as the true correction, or drop them when no objective fact is backed. Drop invented or
- bloated statements. Conservative: when two proposed propositions are really one, keep the better-stated one
- and drop the other.
-- EDGES: the evidence must actually articulate the relation, in the direction claimed. Drop
- direction-swapped or speculative edges.
-- ATTRIBUTION: the QUIZ line's question must genuinely test the attributed proposition. Drop wrong
- attributions to null, or re-point them to the proposition the question actually tests. (Session
- sources only — notes findings carry no attribution; there is nothing to verify.)
-- UNDERSTANDING levels: verify against the quiz outcomes and the session's evidence — or, for notes,
- the author's own words; each note must be
- exactly one word from the fixed scale ("solid", "shaky", "accepted", "resisted", "not yet engaged") —
- reword or drop anything else. No justifications.
+You explore the graph through your tools: find (glob over names + statements + aliases), list_sessions, and
+list_propositions (full statement text, per session). The graph may be large — search, don't assume.
IDENTITY — link-or-create, per proposition:
-- You see the current graph (every node: id, name, statement, aliases). For each verified proposition,
- decide: does an EXISTING node already state this same proposition?
-- If yes: set "linkTo" to that node's id. The session's phrasings will join its aliases and its provenance;
- the node keeps its existing name (labels stay stable across sessions — ignore your name for linked nodes).
-- If no: omit "linkTo" and a new node is created, with the extractor's name as its label. Reword only a
- clearly unglanceable name (an unwieldy sentence of a name); keep it short.
-- When unsure, omit — duplicates are recoverable later; wrong merges are not.
+- For each proposition, search the graph (its key words, its synonyms, its phrasings). Does an EXISTING node already
+ state this same proposition?
+- If yes: set "linkTo" to that node's id. The session's phrasings join its aliases and its provenance; the node
+ keeps its existing name (labels stay stable — ignore your name for linked nodes).
+- If no: omit "linkTo" and a new node is created with the extractor's name as its label.
+- EQUIVALENCE BIAS (owner ruling): paraphrases, rewordings, and compressions of the same claim MERGE. When two
+ statements are the same claim at different precision or from different angles, LINK them. Only genuinely distinct
+ propositions — different claims about the world — stay apart. You are NOT guarding against wrong merges; you are
+ hunting for right ones.
-Also drop propositions not referenced by anything else ONLY if they have no other backing — an unreferenced but
-well-evidenced proposition is still knowledge.
+BRIDGING EDGES — the one place you create edges:
+- You may add edges whose endpoints are an EXISTING graph node id and one of the batch's propositions (use the
+ existing node's real id as "from" or "to"). This is how the new material gets welded into the old graph: when the
+ existing graph's content makes a proposition follow, or grounds it, draw the edge.
+- Keep edges typed like the extractor's: "follows" = derivable; "supports" = grounds without entailing.
+- NEVER drop or rewrite the extractor's own propositions or edges — pass them through unchanged (adding linkTo is
+ the only edit). Never invent propositions.
