feat: Electron desktop wrapper — LearnHarness.app (macOS arm64)
The web app becomes a desktop app without changing shape: the Electron
shell spawns the Next standalone server on a loopback port and points a
sandboxed window at it. All app logic stays in the Next server.
Bands:
1. LH_DATA_DIR seam (config.ts): PATHS.data/chats/graph derive from
process.env.LH_DATA_DIR (else repo data/, unchanged in dev). New
PATHS.modelCache routes the transformers.js embedding-model cache
(~300MB) to <data>/models when the seam is set — the default cache
inside node_modules is read-only in a packaged bundle. All existing
fs writes flow through PATHS; teacherPrompt stays ROOT-anchored
(read-only asset, ships inside the bundle by design).
tests/data-dir-seam.test.ts covers set/unset via child process.
2. Standalone build (next.config.ts + scripts/build-server.mjs):
output 'standalone'; outputFileTracingExcludes data/**/* keeps the
repo's real session data out of the bundle (verified: an unexcluded
scratch build traced 34 files / 716K of real chats + ledgers).
Two empirically-verified tracer gaps required outputFileTracingIncludes:
pi-ai's provider catalog (JSON import attributes — 39 files, 500s on
/api/models without them) and onnxruntime-node's sibling dylib
(libonnxruntime.dlopen via @rpath). build-server.mjs copies public/
and .next/static per docs, refuses a leaked data/ dir, and asserts
the runtime-read prompt .md assets are traced.
3. Electron shell (electron/main.cjs, no preload):
- single-instance lock (two instances would fight over the data dir);
- free port via listen(0); spawn via process.execPath +
ELECTRON_RUN_AS_NODE=1 with PORT/HOSTNAME=127.0.0.1/LH_DATA_DIR;
- BYOK: userData/auth.json, flat {VAR: value} JSON, mode 0600,
merged into the child env only when absent from the real env
(auth UI is the settings milestone; file is hand-editable);
- poll until the server answers (no ready event), then open a
contextIsolation+sandbox window; deny-by-default permission
handler (media allowed only from the loopback origin — mic/STT
groundwork); will-navigate pinned to origin, window.open denied
with external links to the system browser; macOS Edit-menu roles;
- quit path SIGTERM→3s→SIGKILL + exit/SIGHUP nets; child stdout
mirrored to userData/logs/main.log;
- dev mode via LH_DEV_URL: no spawn, points at next dev (HMR).
4. Packaging (electron-builder.yml + build/entitlements.mac.plist):
files = electron shell only; the whole .next payload ships via
extraResources from .next (filter standalone/**/*) — NOT from
.next/standalone directly: electron-builder hard-excludes a copy's
root node_modules and the default pattern is a literal match, so
node_modules/ and .next/ were silently dropped and the server died
with 'Cannot find module next'. Asar holds no native code.
Unsigned (identity: null) until a Developer ID cert exists; hardened
runtime + audio-input entitlements laid now for the STT milestone.
desktop:dev / desktop:dist scripts (electron 44, electron-builder 26).
Live smoke of the packaged .app: server up on a random loopback port,
all API routes 200, a real GLM chat turn answered end-to-end via
auth.json BYOK, chat persisted under userData/data, second instance
exited via the lock, no orphaned server child after quit.
Gates: typecheck, eslint, 500/500 tests (+2 data-dir-seam), build.

feat: extraction coverage — message-granular ledger + token-batched runs (d132373 vision)
THE MESSAGE IS THE UNIT OF COVERAGE (vision-extraction-coverage.md): a per-chat append-only ledger (coverage.jsonl) records which messages the pipeline has extracted, by content fingerprint over exactly what the extraction view sees (one shared line builder — core/coverage.ts); the uncovered remainder is DERIVED at read time, never dual-tracked. A quiz answer merging into the asking message re-opens only that message; plan-block data-part attach never re-opens anything. - The trigger (turn-service) replaces every-3-quiz-answers with uncovered-tokens >= EXTRACTION.chunkTokens (4096) — quiz-less sessions extract too, content size is the honest signal. - runExtraction is now chunked: token-budgeted batches of the oldest uncovered consecutive messages (a tool call + result never split), each merged batch checkpointing its messages' coverage atomically — an abort or error loses at most the in-flight batch; merged batches stay covered. - Observation refs are batch-tagged (obs:<batchTag>:<sourceId>): re-runs of the same batch dedupe; a re-opened message's fresh understanding lands as a new event. Fixes the old obs:p1 position-collision. - New API: GET /api/graph/coverage (exact per-session derived coverage + running flags, most-uncovered first) and POST /api/graph/coverage/extract (manual run for one session, 409 while in flight). - Graph view chrome: the coverage button opens a panel with every session's covered/uncovered tokens and a per-session Extract button — the manual answer to aborted runs, errors, and dormant tails. Renders even when the graph is empty: an empty graph with uncovered sessions is exactly when it matters. Polls only while open. - Notes imports keep the whole-file checkpoint path (coverage undefined). - Tests: pure-core coverage suite (11), chunked-pipeline suite (3: multi-batch + no-op, abort-keeps-earlier-batches + remainder re-run, re-open alone + data-part invisibility), panel render suite (5); pendingQuizAnswers and its tests deleted as dead code. 486/486. Live-smoked on real GLM: manual extract of "teach me modal realism" ran one batch, wrote 4 coverage entries, panel flipped to "1.3k covered · complete" with the button disabled, graph refetched (nodes 11), usage persisted with real stats. |

fix: background-delivery ground rules — the dock is the source of truth, delivered content shows the moment it persists
The owner's three-part test of the context-injection flow surfaced
timing/visibility bugs, fixed as standing ground rules for ALL background
processes (owner rules, 2026-09-15):
1. THE JOB STARTS AT SEND. triggerGraphContext moves from onFinish to
right after the write-ahead persist in handleChatRequest: its only
input is the first typed message (the topic), just made durable — so
embedding + cosine scan run CONCURRENT with the prober's turn and
the dock blob appears the moment the session starts, not after turn
one finishes. Extraction stays at onFinish (it needs answers
accumulated DURING the turn).
2. DELIVERED CONTENT SHOWS MID-TURN. Steers inserted server-side
(claimed at turn start, persisted write-ahead) used to wait for the
next turn's completion to appear — the full record sync mid-stream
is forbidden (it breaks the SDK's in-place continuation merge), so
adoption was deferred to idle. New append-only seam: core
mergeAdopted() inserts the record's new message ids in canonical
order (in-flight streaming tail kept last) and never rewrites a
local message; any other shape bails to the full-sync-at-idle net.
Wired at three points, no new standing polls:
- turn-start window: three bounded record fetches (400ms/1s/2s)
after a send catch the claimed steer while the turn streams;
self-terminating, survives the submitted->streaming flip.
- jobs-poll settle: mid-turn settles adopt append-only NOW, the
owed full sync still runs at idle.
- wake-adoption poll: each tick adopts persisted wake content, so
steers show at the wake turn's START, not its finish.
The dock stays honest with zero gap: jobs hold "running" while
queued behind a pending question ("delivering context"), then flip
done at claim/delivery — visible from start to delivery, and the
turn-start nudge (useActivity().refresh) clears it within ~150ms.
3. THE MARKER IS CLICKABLE (observability). The knowledge-context
SystemLine becomes GraphContextMarker: quiet line, popover with the
delivered propositions IN DELIVERY ORDER (most similar first — the
order the budget filled), each with its folded understanding level;
Esc / outside pointerdown close. The part data was already the audit
trail — now it's readable at the seam where it landed.
Tests: mergeAdopted unit pins (6), marker render pins (3) — 468/468,
tsc, eslint, build all green; live-smoked end-to-end: blob at send,
marker at t+500ms mid-turn, popover order + levels, instant dock clear.

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. |

Semantic topic clusters: local embeddings replace Louvain
Louvain only ever found the reasoning chains (the graph is disconnected by nature — every connected component became its own cluster) and edge-orphans could never join anything. Clusters are now RELATED TOPICS: propositions grouped by meaning. - Embedder (src/server/embeddings.ts): in-process transformers.js v4 running EmbeddingGemma-300M q8 (MTEB 68.4, ~300MB one-time download), MRL-truncated to 512d, "title: none | text:" prefix on 100% of inputs, L2-normalized so cosine = dot. Model/dim mismatch voids the ledger (full re-embed). Injected at the composition root — the agent layer never imports the server layer (architecture law). - Ledger (data/graph/embeddings.json): model + dim + vectors + the persisted cluster partition. Reclustering runs at the END of every embedding batch (post-merge hook, both front doors) — never per read (the agglomerative pass is ~1.5s at 338 nodes). - Clustering (src/core/semantic-clusters.ts): hand-rolled average-linkage agglomerative over cosine (npm HDBSCAN is an abandoned alpha). Stragglers stay singletons by default; attachStragglers is the all-in toggle. Threshold 0.60 swept on the real graph: 26 topics, 74/90 edge-orphans land in real topics, 10 stragglers. - Consumers (snapshot, settle, namer, replay) read the persisted partition — one cluster concept everywhere; core-survival label matching unchanged (20/26 topics kept labels). - Louvain retired: detectCommunities + graphology* deps deleted (graphology-louvain had leaked into the client bundle since the clusters wave); scripts/bench-graph.ts (dead FA2 bench) removed. - scripts/embed-graph.ts: backfill/cold-start (338 nodes in 150s including the one-time model download). |

Cluster gravity: per-cluster centroid pull force in the engine
The 'virtual node' realized as a centroid force: two allocation-free O(n) passes per tick (membership resolved once at sim creation; Float64Array sums). Measured indistinguishable from force-off at 338 nodes (271ms vs 272ms per 400-tick settle). - createGraphSimulation: SimOptions.clusterPull + linkStrength + velocityDecay (physics controls plumbing); degree-scaled link stiffness so linkStrength=1 is exactly d3's default - settleGraphLayout split into layout-settle.ts (it computes the Louvain partition for the pull); layout.ts stays browser-barrel-pure - barrel no longer re-exports clusters.ts: graphology + louvain are fully out of the client bundle (verified against built chunks) - replay passes the per-batch partition; CLUSTER_PULL_STRENGTH=0.15 tuned by sweep: cluster spread 63->36 world units, centroid separation and total span unchanged (no blob merge, no collapse) |

Live physics drag + splat cluster regions
The renderer grows a live d3 sim (createGraphSimulation, shared with the server settle): pointerdown on a node pins fx/fy and pointer capture (preventDefault kills the compat mousedown, so d3-zoom never pans); the first CLICK_SLOP-exceeding move reheats to alphaTarget 0.3; release un-pins and the sim anneals (release-and-relax) — alpha < 0.005 settles it, a 250ms debounced onCommit PUTs the rest state. Verified live: 123fps during a 320ms drag (regions rebuilding every 3rd frame), 85-tick settle, then zero idle frames. A slop-free press stays a click (select, no reheat, no commit). PUT /api/graph/positions sanitizes (finite coords, known ids) and if the graph grew mid-drag runs ONE incremental settle with the client's arrangement as anchors (50-id PUT test: anchored drift 0.15). Cluster regions swap convex hulls for a low-res world-space SPLAT bitmap: per-member radial-gradient discs (alpha 0.2) + intra-cluster edges as round-cap strokes (Minkowski dilation — concave shapes finally render), upscaled with bilinear smoothing (the upscale IS the blur, no ctx.filter: Safari). One tiny blit per frame replaces 32 clusters x 4 offset Path2D polygons re-rasterized at DPR 2 (the old GPU coil-whine path); during the live sim the bitmap rebuilds every 3rd frame. cluster-geometry.ts retires convexHull/offsetPolygon/traceRoundedPath (tests follow; clusterHue stays). Region labels stay (centroid + clusterHue, inverse-gated on zoom). |

World-space rendering: geometry cached once, zoom pays only rasterization
Fixes the zoom frame-rate collapse and rebuilds draw() around a single camera transform, per the user's Obsidian-style sizing proposal. Bug fix first: the eased zoom leaked a queued rAF callback per frame -- advanceZoom applies each step through d3-zoom, whose zoom event called markDirty() from inside the tick loop, scheduling an extra draw while the loop scheduled its own. Draws multiplied per displayed frame; sustained wheel ran at ~20fps against a 120Hz display. markDirty now skips scheduling while inTick (verified: 62 frames/500ms during a 28x zoom burst, matching pan). World-space model: every draw call now runs in graph coordinates under one setTransform(k). Sizes are defined as screen-px-at-fit and converted once per geometry build (/ kFit), so nodes, node labels, arrowheads and the hover halo scale with the graph as you zoom (0.25x painted area at half zoom, exactly k^2) while edge widths and hull borders stay viewer-relative hairlines (/ k). Cluster hull geometry (convex hull + three offset fills + solid boundary -- dashes dropped for now) is built as cached Path2Ds per data/visibility/settings change; camera moves do zero geometry math, making zoom per-frame cost identical to pan. Label wrapping runs once per build, not per frame. Region labels stay viewer-relative (18px at any zoom) as UI chrome. Picking radius scales with the world-sized discs. Glide feel: ZOOM_EASE_MS 120 -> 45, convergence 0.1% -> 0.2%; a notch now settles in ~260ms instead of ~750ms. Resize still paints synchronously. Also fixes barrel-law lint violations from the settings wave (import from @/src/core and @/src/server, not deep module paths). |

Notes front door: format-agnostic import into the graph pipeline
The same extractor→auditor→merger pipeline now runs over raw personal
notes in arbitrary formats (vision §1, DECIDED 2026-09-13):
- NotesSource records (data/graph/sources.json, deterministic id from
path hash → idempotent re-imports) play the chatId role in mappings,
checkpoints, and observation events; usage lands on the source record
(appendSourceUsage, idempotent per startedAt, kept across upserts).
- mergeFindings is chat-store-free: callers pass MergeSource
{messages, foldedAt} — sessions pass the chat record, notes pass
messages:null (no quiz-event rebuild; a deterministic rebuild needs
structured quiz tool parts).
- Second extractor prompt (NOTES_EXTRACTOR_INSTRUCTIONS) for general-
purpose extraction; understanding judges the AUTHOR's grasp. Auditor
wording input-agnostic. extract/audit share one generic runSubmitAgent.
- graphSnapshot.fileSources (srcId→filePath); notes sources render as
static path entries in the detail card (FileTextIcon, never a link).
- One shared pipeline instance (exported from chat-handler): same
single-flight registry, live status chips (label = file path), usage
accounting, and true abort for both front doors.
- Transport: POST /api/graph/import (multipart, 3-wide worker pool) +
Import notes… button in the graph view; scripts/import-notes.ts for
batch runs (concurrency 4).
- real-data-extraction/ gitignored (raw import sources never committed).
355/355 tests; typecheck, lint, build green.

feat: model + thinking control — the stats bar's picker, on pi-ai's catalog
The model-control wave (user-decided design, 2026-09-12): ONE controller
for the conversation agents (prober/teacher are functionally one agent);
background sub-agents stay config-pinned. pi-ai owns the registry — the
shipped 366-model OpenRouter catalog (cost, context, modality,
thinkingLevelMap), getSupportedThinkingLevels/clampThinkingLevel for the
per-model thinking truth, and streamSimple's automatic clamp. No second
registry to drift out of sync.
Seams:
- config.ts: ReasoningEffort retired for pi's ThinkingLevel
(off|minimal|low|medium|high|xhigh|max). GLM roles go honest at "low" —
pi's catalog says GLM-5.3-flash accepts exactly low|high|max, and the old
"minimal" was silently clamped to low by streamSimple since the swap;
nothing changes behaviorally. visualMaker → qwen/qwen3.8-flash (fixes
the dead qwen/qwen3.8-max slug — the catalog only ships -0902; also the
user's cost pick, 0.15/0.47 per-1M).
- src/agent/models.ts: piEngineFor(role, settings?) — provider+id resolved
from the catalog, thinking level from settings ?? config, CLAMPED to the
model's supported list (a settings change between models can never send
an invalid level). PiEngine gains `level` (observability/tests).
- ChatRecord.settings {model?: {provider, id}, thinkingLevel?} — written
by PUT /api/chats/[id]/settings (replace-whole, no updatedAt churn),
read by chat-handler at turn composition: agents are stateless per turn,
so the change is next-turn-effective by construction. The turns log
still records the ACTUAL billed model (the honest witness).
- GET /api/models: the configured-provider catalog as client-safe DTOs
(core/contracts/models.ts) + config defaults; a second provider joins
the picker by registering it in piModels() — nothing else changes.
- PUT settings validation gate (src/server/model-catalog.ts): unknown
provider/model or unsupported level → 400 carrying the supported list,
never a silent clamp.
- scripts/sync-pricing.ts: regenerated PRICES/CONTEXT_LIMITS from pi-ai's
shipped openrouter.json (offline; same source as the engine + picker).
All 366 models priced; glm's stale 0.15/0.5 → pi's 0.075/0.25, limit
1310720 → 1048576 — cost is inferred at read time, so history re-prices.
- UI (components/model-picker.tsx): stats-bar right side becomes model +
thinking buttons; menus open ABOVE; fuzzy search over "provider id
name" (core/fuzzy.ts — pi's /model pattern); model rows show name/id/
price/context; the thinking menu lists exactly the chosen model's
supported levels (GLM: low|high|max — no dead options, no "off").
Model switch drops an incompatible pinned level (falls back to config,
which clamps honestly) rather than carrying a 400.
Tests (350/350, +15): catalog projection + defaults, the settings gate,
pi thinking truth pinned against upgrades (glm low|high|max; minimal→low;
off→low — GLM cannot disable thinking), the engine factory's
override/fallback/clamp/throw matrix, fuzzy ranking, store round-trip,
and the re-priced folds (usage, stats bar, activity dock).
Live smoke (disposable driver, deleted): catalog route 366 + defaults;
glm+minimal → 400 + supported; turn 1 billed qwen/qwen3.8-flash under
the override; mid-session switch flipped turn 2 to glm; clear-overrides
restored the config pin. ALL CHECKS PASS on real OpenRouter.

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.

fix(bridge): gate tool-input-available on clean execution — invalid tool inputs never reach the dock
Live crash (modal-realism session): GLM double-encoded the quiz options array as a JSON STRING inside the tool-call arguments. The bridge emitted tool-input-available at toolcall_end — BEFORE validation runs — so the client briefly saw the malformed quiz as a pending question and the dock crashed in normalizeOptions ((string).map). The later tool-input-error chunk could not revive the tree. The old SDK gated this with InvalidToolInputError: validation ran before the input-available chunk. The bridge now holds the part in input-streaming until tool_execution_end and only then emits tool-input-available (clean) or tool-input-error (invalid, structural JSON Schema failure or the zod re-run inside execute). Server-side behavior was already correct (the record shows the error part + a successful model retry) — this is purely the wire-ordering hole. Pinned in chat-flow.test.ts: the refinement-layer retry (correctAnswer mismatch) and the exact live structural shape (string options) both assert the invalid call never becomes input-available on the wire.

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). |

Fix turn-usage keying: idempotent per request turn id, not messageId
Live smoke exposed two bugs in the turn usage log: - onFinish messages carry no ids (withMessageIds fills copies inside persistTurn), so fresh turns keyed messageId "" — provenance lost. - The SDK coalesces continuation turns into ONE response message (a whole probe conversation lands in a single assistant message), so per-messageId idempotency swallowed every continuation turn's usage. TurnUsage gains id: string (unique per request, the append idempotency key); messageId stays as transcript provenance, taken from the id-filled list. appendTurnUsage dedupes by id; continuation turns with the same messageId each keep their usage. |

Master seam: plan-block emission + turn usage capture
- src/core/plan-blocks.ts: pure emission builder — full block on successful plan_init, neighborhood block when the derived plan state moved since the newest existing block; the as-of state reads from the block's frozen snapshot (transcript quiz parts mutate in place on answer, so re-derivation is post-mutation blind). Idempotent by construction. - turn-service persistTurn enriches with withPlanBlocks at the canonical write; chat.tsx adopts the record once the server agrees the turn is done (endTurn flips only after persist). - chat-handler: per-request usage collector via agent-level onStepFinish (StepResult.usage), appended at onFinish to ChatRecord.turns via appendTurnUsage, idempotent per response message id. |

Extraction observability: usage capture, live status payload, true abort (Wave 4)
Extraction is real spend and background work; the dock needs to see and stop it. User decisions: persist all cost data (chat record), per-stage usage granularity, and TRUE cancellation for abort. USAGE CAPTURE (live + persisted): - extraction.ts: per-call onStepFinish captures each billed step's usage (SDK LanguageModelUsage -> CallUsage: input/output/cache read+write/reasoning) into the registry's live per-stage usage (extractor/auditor; the merger is deterministic — no model call). - /api/graph/status runs now carry usage (model + steps per stage); cost/context folds are the consumer's (core/prices.ts — nothing stores dollars). - ChatRecord.extractions: append-only per-run usage log (mirrors the turns log): startedAt key, at, durationMs, merge stats when the merger ran, stages. Persisted on success AND failure — a failed run still spent money. Idempotent per startedAt; the list payload (ChatSummary) never leaks it. - EmissionStats moved to contracts/graph.ts (its contract home); core/graph.ts re-exports for existing importers. - Verified end-to-end against the real pipeline (backfill one chat): per-step token counts, reasoning tokens, and the auditor's growing prompt-cache reads captured and persisted. TRUE ABORT (the dock's abort button, user decision): - RunningExtraction owns one AbortController per run, shared across phases; abortExtraction(chatId) fires it and returns whether a run was aborted (idempotent no-op otherwise). The pending model call receives the signal — the provider cancels the request, spend stops. throwIfAborted() at phase boundaries ends runs aborted in sync gaps. - Abort is a deliberate stop, not a failure: same ledger discipline (nothing merged, nothing checkpointed, partial usage persisted) but the run reports zero emissions instead of throwing. Exported via src/server/observability.ts for master's /api/activity/abort route. - Tests: mid-run abort (hanging mock that rejects on the signal), live-accumulation + persisted-record assertions, store-seam idempotency, and the summary-payload leak guard. |

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. |

Activity feed: one dock-shaped GET /api/activity (cross-chat processes)
The dock is visible in every view, so it needs every running process — sub-agent jobs across ALL chats (not just the open one) plus the global extraction runs — in one poll. /api/jobs stays chat-scoped and untouched: it is the transcript machinery's poll and carries turnInFlight for the re-attach seam (chat-transport), the seam we spent three live rounds stabilizing; making it polymorphic would fork its response shape by mode and put regression risk on exactly the wrong path. The dock is a different consumer with a different shape (cross-chat, running-only, cost-bearing), served by a thin route over server/observability.ts: - activityFeed(): running jobs from every chat (title-joined, oldest-first on last activity) + extraction runs + busyChats (chats with a teacher turn in flight — the biggest spender; data made available, rendering is a dock decision). - GET /api/activity — the dock's single poll everywhere. - Cost math stays client-side (core/prices.ts folds); raw usage rides the records and the transport stays thin. Decided with the user over the polymorphic-/api/jobs and separate-all-jobs-endpoint alternatives. |

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: dedupe same-id continuation copies in persistTurn (coalescing follow-up)
With a steer coalesced into a quiz-answer continuation, the steer sits AFTER the assistant message being continued, so the SDK's onFinish list carries the input copy AND the extended response copy as two entries with the SAME id — persistTurn saved both, the jobs poller's syncFromServer imported the dup, and React keyed a single message twice (the user's live test hit it). withMessageIds now dedupes by id keeping the LAST occurrence — the SDK's final merge state (a superset of the earlier copy) — which also yields the right semantic shape: [user, steer, assistant(extended)]. Out-of-lane surgical touch (flagged for master review): turn-service.ts. Squashed the live session's already-corrupted record by hand (same dedupe). |

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. |

Wave 2: 409 merge-retry transport, dead pendingJob code, evidence-based timing, prompt-size guard
- components/chat-transport.ts (NEW): createChatTransport(chatId) — the chat.tsx seam is now a one-line swap. Its fetch turns a 409 on POST /api/chat (a learner send racing the wake pipeline's ~1s adoption window) into: wait out the in-flight turn (poll turnInFlight, 30s cap), refetch the record, MERGE the outgoing messages onto the fresh server list, re-POST. A bare retry would clobber the steer + wake messages via the write-ahead persist (steerDelivered makes that loss permanent) — merging is the whole point. Unit-tested: pass-through, wait+merge+reorder, dedupe by id, repeated-409 loop, bounded give-up. - src/core/pending.ts: findPendingJobCall deleted (dead since wave 1 — job tools resolve server-side with an ack, nothing pends client-side). JOB_TOOLS kept (runner.ts still uses it). Header doc rewritten. - src/server/jobs.ts: GRACE_MS 1500 → 750, with the evidence in the comment: the race window is only the learner's answer→POST flight (sendAutomaticallyWhen dispatches synchronously; ~10ms localhost, <300ms realistic RTT — 750 is 2.5× worst case) and misses self-heal via the pump's gate recheck, the 409 backoff ramp, and the new transport merge-retry. POLL_MS=400 kept (sampling granularity only). - tests/jobs.test.ts: prompt-size guard — every fragment ≤8k chars, composed prompt ≤60k — the README-leak class (815 bytes ≈ 200 tokens per teacher turn before wave 1's fix) can't silently recur. Gates: typecheck, 279/279 tests, lint, build — all green. |

fix: live sub-agent observability — dispatch cards, steer artifacts, sidebar panel
The pi-style ack protocol (previous commit) left the client describing the
old world: artifact cards read the ack string as a result ("could not be
displayed"), the only job poller rendered on input-available parts that no
longer exist (so wake turns landed invisibly until re-navigation), steers
rendered as learner bubbles with no SVG anywhere, and server-persisted
assistant messages carried empty SDK ids (duplicate React keys).
- persistTurn (turn-service): fill empty message ids at the canonical write
— server-only messages (last turn's, wake turns') now key uniquely;
client-authored ids untouched.
- chat.tsx: ONE central /api/jobs poll (fast while jobs run, slow discovery
cadence, off for job-less sessions) drives every job surface, re-syncs
once when a job settles (the record already holds the steer + wake
response at flip time), and adopts server-side wake turns via the same
turnInFlight machinery as returning mid-turn. Steers branch to the
artifact card — never a bubble. Composer no longer gates on jobs.
- /api/jobs now reports turnInFlight alongside the job list.
- dispatch-card: the tool-call box — live activity by toolCallId while
running, quiet "delivered"/"failed" one-liner after; the ack is visible
observability, the artifact lives in the steer.
- steer-card: renders the delivered artifact by kind (research brief /
sanitized SVG / sandboxed demo iframe) from the data-subagent-artifact
part; result renderers extracted and exported from the artifact cards.
- sub-agents-panel: right-sidebar section above the plan tree listing
running sub-agents (kind, elapsed, live activity) — vanishes when idle.
- tests: dispatch/steer/panel render tests re-target the new protocol;
persistTurn id-hygiene suite. 229/229 green, build green.
Out-of-lane touches for master review: chat.tsx + components/** (cleared
this wave), app/api/jobs/route.ts, src/server/turn-service.ts, contracts
protocol doc §2. Live-verified on :3003 (full loop, SSR DOM checked).

Pi-style ack-and-steer sub-agent protocol: dispatch mid-turn, steer via server wake turn
The job tools (research/demo/visual) switch from client-side turn-breaking calls to pi's model: execute resolves IMMEDIATELY with a fire-and-forget ack, the teacher's turn continues, and the result arrives later as an injected user-role steer message that wakes the teacher in a new server-side turn. - contracts.ts: THE ASYNC PROTOCOL rewritten (ack now, steer later); steer types (SubagentSteerMessage, metadata.subagentResult + data-subagent- artifact part), pure buildSubagentSteer/steerDelivered/isSubagentFailure - tools/jobs.ts: jobTools(ctx) factory — server-side execute creates the job (deduped by toolCallId), fires spawn with the dispatch-time input (the part isn't persisted yet at execute — a transcript scan would race) - runner.ts: runJob(jobId, input?) builds the steer and hands it to the injected deliver seam; pipeline owns the done/error flip (a polling client re-syncs once, at the end); failures still steer - server/jobs.ts (new pipeline): per-chat serialized queues on globalThis, idle gates (turn liveness + pending question, 1.5s grace), 409 retry with backoff, idempotent per jobId, stale-job recovery sweep (re-deliver or re-spawn); wake turns run through the same handleChatRequest composition via setTurnRunner injection - chat-handler.ts: wires runner+deliver+tools ctx; drops spawnTurnJobs from onFinish; teacher default registry = question tools only - plan.ts: PlanToolContext split out (plan tools need no job wiring) - visual-maker: edit_svg added (pi parity — exact-match single replacement, fuzzy context on a miss); researcher: pi's kept/dropped source accounting restored - prompts 20-jobs/40-demos: async discipline rewritten (announce and keep teaching, no waiting/polling/fabricating, parallel dispatch, teach with the artifact when it arrives) - tests: jobs.test.ts rewritten (dispatch ack mid-turn, runner steers, wake pipeline: deferral/409/idempotency/failure), demos.test.tsx runner tests ported to runJob + fake deliver; 222 green FLAGGED surgical touches outside the stream's owned files, for master review at merge: src/core/contracts.ts (protocol doc + steer types), src/core/ui-message.ts (job tool + data-part types), src/server/ chat-handler.ts (wiring), src/server/turn-service.ts (spawnTurnJobs retirement), src/agent/teacher-agent.ts (default tools), src/agent/tools/ plan.ts (context type split). Verified live on PORT=3003 with real models: teacher dispatched research mid-turn, researcher ran real searches/fetches, steer injected on quiz answer, wake turn wove the brief in citing its sources, job flipped done; a client/wake race correctly 409'd. |

Fix turn-liveness registry across Next dev module instances (globalThis)
In Next dev (Turbopack), each route compiles as its own entry — a module-level Map in turn-liveness.ts was a DIFFERENT instance in the page render, GET /api/chats/[id], and POST /api/chat. The chat route held the live turn (hence the 409), but the page render read an empty registry: initiallyInFlight=false → mount continuation fired a send → 409 → the 'Something went wrong' banner on returning mid-turn. The registry now lives on globalThis (the standard Next singleton channel) — one Map per process regardless of module instances. Semantics unchanged (TTL leak guard, begin/end round trip). Browser-verified end-to-end (headless tester): answer quiz → navigate away → return mid-turn → graded card (no re-prompt), 'Thinking…' shimmer, composer gated, no error banner; teacher response auto-delivered when the background turn finished. Polling GET /api/chats/[id] observed working. |

Sessions keep running across navigation: turn liveness + write-ahead persist
The bug: answering a quiz and navigating away mid-turn, then returning, re-prompted the same question. Root causes: (1) the answer was durable only at onFinish — every mid-turn view read the stale pre-answer record; (2) the server had no notion of a turn in flight; (3) remount treated the stale record as current, with no re-attach path. Worse, the stale dock let the quiz be answered again, racing two turns into a last-writer-wins saveMessages clobber. Fix (four pieces): - Write-ahead persist in chat-handler: the request body IS the client's canonical state — saved to disk BEFORE the stream starts. The answer is durable the instant the request arrives; crashes recover via the existing mount continuation. - Turn liveness registry (src/server/turn-liveness.ts): in-memory chatId → in-flight map with a TTL leak guard; beginTurn rejects concurrent turns (409) so one turn ever owns a chat. endTurn runs in onFinish AFTER persistTurn, so pollers that see not-in-flight always read a finished record; a turn-start failure clears the registry (no lockout). - GET /api/chats/[id] reports turnInFlight; the chat page passes initiallyInFlight to the client. - Client re-attach (components/chat.tsx): while in flight, busy shimmer + composer gated + mount continuation suppressed; poll /api/chats/[id] until the turn finishes, then syncFromServer adopts the completed transcript. Stop stays local-stream only (a server turn has no client request to abort). Verified by scripted-model tests: concurrent turn 409 + registry lifecycle, write-ahead durability mid-turn, failed-turn lockout guard. |

Quiz hardening: cross-field schema validation rejects ungradeable quizzes
quizInputSchema now enforces (via pure quizInputProblems + superRefine) that correctAnswer resolves against option values, options are non-empty and unique, and multi-answer requires multiSelect — schema-valid now implies gradeable. The AI SDK already returns invalid tool input to the model as a tool-error part (verified in ai@7 run loop), so the teacher retries in the same turn. chat-handler onError passes tool-input validation messages through to the client (masked 'An error occurred.' for everything else). Covers the Gate 3 GLM failure: correctAnswer slug matching no option. |

Extraction pipeline: extractor → auditor → merger — the sole graph writer (stage 5)
The knowledge graph's write channel is now the pivot's target
architecture (vision §1 construction):
- src/agent/subagents/extraction.ts — the pipeline factory
(createExtractionPipeline({ chatStore, graphStore, extractor?,
auditor? }); models env LH_EXTRACT_MODEL ?? LH_MODEL):
* transcriptView(): the compact view both LLM stages see — final plan
tree with node ids, conversation verbatim, QUIZ lines with outcomes,
mark_done lines; job tool parts are one-liners, plan ops fold into
the tree line.
* Extractor: transcript → SessionFindings (propositions incl.
misconceptions and prose-only supports edges, attribution for
UNTAGGED probes, all with verbatim evidence) via one zod-validated
submit_findings call.
* Auditor: transcript + findings → the verified subset + drops (the
faithfulness net) via submit_review.
- src/core/graph.ts — emitChat/foldStaleChats/replayFinalTree retire;
mergeFindings() replaces them as the pipeline's deterministic apply
stage: exact/alias identity resolution (one mapping line per (chat,
graph node)), edge dedupe, and event rebuild FROM THE TRANSCRIPT's tool
parts — kinds/timestamps/refs/notes deterministic, the LLM's only event
say being WHICH proposition an untagged probe tested (retroactive —
the vision's open question #3, resolved structurally: tagged events
resolve deterministically; attribution rescues untagged and
tagged-but-unmapped ones; unattributable land null + question text).
pendingQuizAnswers() is the trigger helper.
- Trigger (turn-service.ts triggerExtraction, replacing the old
foldTurnIntoGraph body): once a chat accumulates
EXTRACTION.everyNQuizAnswers (LH_EXTRACT_N, default 3) new answered
quizzes, fire the pipeline async — single-flight per chat, failure
checkpoints nothing and re-runs on the next trigger. Deliberately a v1
placeholder isolated in ONE seam, trigger-agnostic pipeline.
- GET /api/graph is now a pure read (foldStaleChats gone).
- NodeMapping.treeNodeId → sourceId (the mapping key is now the writer's
local proposition id — tree node when tree-derived); store strict-read
schema updated. Local ledger data regenerates through the pipeline.
- Tests: graph.test.ts rewritten around mergeFindings (identity,
attribution paths incl. ghost-rescue, idempotency, cross-session
provenance, trigger counting), graph-context.test.ts merge section
converted to findings-driven, NEW extraction.test.ts — transcriptView
units + the full pipeline with mock models (audit drops, failure
checkpoints nothing, single-flight). 195/195, tsc/eslint/build clean.
Probe attribution (vision open question): probes attach retroactively by
the extractor against the whole transcript; a pre-tree probe maps to a
proposition the tree only articulates later. Fuzzy/embedding merge
adjudication stays deferred (conservative exact/alias only).

Turn services + agent DI: chat-handler becomes the composition root (stage 4)
The chat turn is now composed, not implemented, by chat-handler.ts:
- src/server/turn-service.ts: one named, error-contained seam per turn
responsibility — buildTeacherContext (W8 read channel), persistTurn
(canonical state write), spawnTurnJobs (async protocol kick-off),
foldTurnIntoGraph (session→graph consolidation; the extraction-pipeline
stage swaps this body behind the same seam). Each takes its deps
explicitly; failures log one [chat <id>] line and never touch the
response.
- chat-handler.ts wires: storage ports (stores), the job runner, the
teacher tools (ctx = chatId + injected ChatStore), and the services.
It no longer contains any logic beyond request validation.
Agent layer now receives dependencies instead of importing them — a new
lint zone enforces it (src/agent never imports src/server or src/store;
verified to fire both ways):
- runner.ts: createJobRunner({ chatStore, jobStore }) factory returning
the spawn hook + the three job runners; the model-override test seam
stays module-level. Bodies otherwise verbatim.
- plan tools: persist through the ctx-injected ChatStore
(TeacherToolContext = { chatId, chatStore }).
- teacher-agent's dependency-free default registry is now the true
client-side set: questionTools + jobTools (jobTools was ctx-parameter-
shaped but never used its ctx — now honestly context-free). Production
always passes createTeacherTools({ chatId, chatStore }); tests that
drive a bare mock model get the client-side set unchanged.
Zero behavior change: tsc clean, 190/190 tests, eslint clean, production
build clean. Tests inject the same fs ports the chat-handler does.

Storage ports: ChatStore/GraphStore/JobStore + adapters + core inversion (stage 3)
Per-entity semantic ports (src/core/ports.ts), one adapter family
(src/store/*, fs JSON/JSONL), exactly one composition point
(src/server/stores.ts). Dependency direction is now machine-checked:
adapters implement core interfaces; core never imports an adapter.
The inversion:
- core/graph.ts (emitChat/getGraph/graphSnapshot/foldStaleChats) is now
pure — it takes the storage ports as explicit parameters (GraphDeps).
No store imports; newGraphNodeId is local; node id format unchanged.
- core/graph-context.ts buildGraphContext() no longer defaults to the
live ledgers: the chat-handler hands in getGraph(graphStore) per turn.
- store adapters export exactly one object each implementing their port
(chatStore/graphStore/jobStore); bodies otherwise verbatim.
NodeMapping + SessionCheckpoint moved store/graph -> core/contracts
(they ARE contract shapes); CreateJobInit/JobPatch live in ports.
- titleFromPrompt moved store/chats -> core/contracts (pure helper,
planNodeStatus precedent). Store modules now contain persistence only.
- server/stores.ts is the composition root; server/{chats,graph,jobs}.ts
and chat-handler wire from it; agent (plan tools, sub-agent runner)
call the port objects. The shell surface (@/src/server exports) is
unchanged.
Lint law extended: the whole of src/core is now a purity zone (was a
file glob with a graph/graph-context exemption). Verified it fires on
core->store imports; tsc clean, 190/190 tests, eslint clean, prod build
clean (prerender 6/6). Tests pass deps explicitly — graph.test uses the
same fs-adapter pair stores.ts wires in production; graph-context.test
keeps its in-memory ledgers as a GraphStore implementation.

Shell/core import law: public API barrels + ESLint enforcement (stage 2)
The shell now imports through exactly two barrels, enforced by
import/no-restricted-paths (npm run lint):
components/** -> "@/src/core" (pure core API, browser-safe)
app/** -> "@/src/core" + "@/src/server" (server entries)
Zone violations are lint errors with architecture-pointer messages; the
pure-core modules (contracts, question-core, plan-tree, phases, pending,
math-delims, ui-message) may never import agent/server/store.
Supporting moves (direction: IO layers -> core):
- core/index.ts: the core public API barrel
- core/ui-message.ts: moved from src/agent (it was shell-facing all along)
- quiz/ask input zod schemas moved agent/tools -> core/question-core
(the question contract, alongside the grading logic)
- ChatRecord/ChatSummary moved store/chats -> core/contracts (single schema)
- GraphSnapshot/NodeStateClass moved core/graph -> core/contracts (the
/api/graph payload IS a contract; the pure renderer needs only these)
- src/server/{chats,graph,jobs}.ts + index.ts: thin server entries for the
transport layer; GET /api/graph's fold side-effect now lives behind
graphView() instead of inline in the route
Gates: tsc clean, 190/190 tests, eslint clean (law verified to fire on
store/agent/subpath violations), production build clean.
(Repo repair en route: a git object (app/chat/[id] tree) was missing from
the object store — reconstructed byte-exactly via mktree from its blob;
the broken node_modules that stalled the build was cleanly reinstalled.)

- src/store/jobs.ts: per-job JSON store in data/jobs (create/get/update/list, dedup by toolCallId) - src/agent/tools/jobs.ts: research tool — client-side (no execute), turn ends at the call; input per contracts ResearchToolInput - src/agent/tools/web.ts: server-side web_search (Google CSE) + web_fetch (Readability/Turndown/linkedom, Jina fallback) — errors return as strings, never thrown into the agent loop. Deps: @mozilla/readability, linkedom, turndown (+@types/turndown dev) - src/agent/subagents/researcher.ts: isolated ToolLoopAgent (web tools only, 12-step cap), researcher prompt ported from pi - src/agent/subagents/runner.ts: spawnPendingJobs hook + runResearchJob — fire-and-forget, activity line per tool call, fulfills the part in the LATEST chat record (output-available) before flipping job status; failure still fulfills the part so the teacher learns the outcome - src/server/chat-handler.ts: onFinish spawn hook after saveMessages - app/api/jobs/route.ts: GET ?chatId= polling endpoint - components/artifacts/job-card.tsx + registry entry: polling activity card (2s) → syncFromServer on finish; research-brief card (markdown + sources) - src/agent/prompts/20-jobs.md: research doctrine for the teacher - tests/jobs.test.ts: store CRUD, spawn hook via scripted mock teacher, runner completion/failure with fake model + stubbed fetch |

Wave 0: shared contracts + extension points
- src/core/contracts.ts: plan tree / graph / ledger / job protocol / artifact
registry types — the single source of truth for all workstreams
- tools: per-request factory createTeacherTools({chatId}) composing
questionTools + planTools (stub) + jobTools (stub); quiz gains nodeId
- prompt composition: system-prompt.md + sorted src/agent/prompts/*.md
- ChatRecord.tree + saveTree; pending gate scoped to quiz/ask (+findPendingJobCall)
- chat.tsx: artifact renderer extension point + ChatActionsContext.syncFromServer

v3: AI SDK pivot — pi removed, Next.js 16 + AI SDK 7 + AI Elements teacher app
The teaching agent no longer runs on pi. Stack: - ToolLoopAgent (ai@7) + OpenRouter (OPENROUTER_API_KEY), model via LH_MODEL, default anthropic/claude-sonnet-4.5 with reasoning tokens - quiz/ask_user_question = client-side tools (no server execute): the call lands as a typed tool part in input-available state; the card grades via src/core/question-core.ts; addToolOutput sends the verdict; the teacher's reaction continues the same assistant message - resume-mid-quiz is free: the pending tool part persists in the transcript - persistence: one JSON per chat (data/chats/), full UIMessage transcripts, saved onFinish (also on abort) - UI: AI Elements (owned copy-paste components, pruned to the five in use) + button-based QuizCard/AnsweredCard (ask answers never graded) - pi fully removed: TUI, extensions, Fastify+WS server, bridge, custom protocol all deleted (recoverable from git history) - tests: question-core units carry over; chat-flow integration drives handleChatRequest with MockLanguageModelV4 (48 tests, zero tokens); render smoke tests guard the cards (renderToStaticMarkup) Carried over unchanged: teacher system prompt, question-core, schema/ ledger/derive/extract pipeline, data model. |

v2 web interface: fix delivery races, real URLs, optimistic echo, thinking stream, button-based quiz UI
Root causes of the v1 browser bugs (all fixed + covered by deterministic tests): - duplicated messages: per-socket snapshot + global broadcast marking raced; replaced with a single append-only entry log (exactly-once per socket, structurally) — covered by tests/server.test.ts - delayed/missing echo of own messages: optimistic append with sending/failed status, reconciled by text when the real entry arrives - no thinking shown: thinking deltas streamed live (kind: thinking) and persisted in assistant entries so they survive reloads - ask answers graded as wrong: AnsweredCard no longer applies quiz grading to ask answers (no ✓/✗, no verdict) - broken option selection: native radio/checkbox inputs fighting React state replaced with button-based options (single source of truth, one-click select) - no URLs: History API routing — / home, /s/<file> per session (deep links, refresh, back button); session view resumes its file on mount - lost connection = dead UI: exponential-backoff reconnect with full resync - stick-to-bottom transcript with jump-to-latest pill Server: startServer() with injectable runtime factory (scripted model in tests); createSession returns file for routing; scripted model gained thinking turns. 51 deterministic tests green. |

v1 web interface: dispatch-mode quiz/ask, Fastify+WS server, React frontend, deterministic test suite
- extensions/core/question-core.ts: pure quiz/ask logic (normalize/shuffle/resolve/grade/format) shared by both interfaces - extensions/core/bridge.ts: in-process server<->extension bridge (answer/dismiss/re-arm) - extensions/quiz-web.ts + ask-web.ts: web dispatch mode — tool returns immediately, graded answer arrives as next user message; sessions resumable mid-question via lh_question/lh_question_answered custom entries (never in LLM context) - extensions/quiz.ts: refactored onto shared core (terminal blocking mode unchanged) - src/server/index.ts: Fastify + WebSocket; REST (list/create/resume), entry sync (diff-based, all message kinds), streaming deltas, pending-question push - web/: Vite + React — home view (graph placeholder, session list, new-session input), session view (markdown+KaTeX+mermaid transcript, quiz cards, streaming) - src/testing/scripted-model.ts: deterministic fake LLM (scripted model runtime injected via factory overrides) - tests/: 48 deterministic tests (unit: question-core + bridge; integration: full pi loop with scripted model incl. resume re-arm) - scripts/e2e.ts: live smoke test (manual, real LLM, never a gate) - teacher/system-prompt.md: end-your-turn rule for question tools |
