streaming: connection diet — the parallel-session freeze, fixed
Root cause (postmortem, verified live): Chromium caps 6 concurrent
HTTP/1.1 connections per origin. Every running turn pinned slots for
its whole life — the POST /api/chat response stream plus a reattach
GET stream per visit that never closed on navigate-away — so two
concurrent thinking sessions starved navigation RSC fetches in the
browser queue (147s measured) until the turns settled. Server was
exonerated (3ms curls during the freeze); main thread idle throughout.
- COMPACTION LAW + WIRE DIET (ui-stream): store the states, not the
chunks — replace-in-place snapshot retention keyed by updateSlots,
~100ms coalesced latest-wins fan-out, slim wire drops pi's duplicate
assistantMessageEvent payload.
- DIET B: POST /api/chat acks and closes ({ok:true}) — the turn wire
is GET /stream for everyone, submitter included; send() reattaches
via refetch-first resumeStream(true).
- DIET A: unmount cleanup calls model.stop() — navigating away aborts
the view connection (turns are server-side background objects).
- Answer-flicker fix: resumeStream's eager tail clear moved off the
refetch path (the refetch swaps base+tail atomically; clean-slate
guard restored on refetch failure) — the optimistic answer card
survives refetch latency (1.7s stalls measured on dev).
- Tests converted to the ack contract (drainTurn/drainRunning helpers,
dietFetch mock) + a pin that the POST body reads while the turn runs.
Gates: 1489/1489, typecheck, lint. Live: dual streaming sessions,
navigations 335-648ms, in-page settings 19ms (was 147s).

compaction: the service — settle kick, turn-start gate, registry mutex (round 14 slice 2)
- src/server/compaction.ts: ensureCompacted (the turn-start gate — awaits
in-flight compaction, compacts synchronously when still over threshold),
kickCompaction (the settle kick — summary starts inside the learner's
reading/answering pause; question/problem poses end runs so the pause is
always a between-runs window), registry mutex on globalThis, anti-churn
guard (empty-span skip), summary via the zero-tool one-shot sub-agent
seam on the session's OWN engine (owner ruling), usage to the turns log
keyed by the marker, record-changed + compaction-changed events
- chat-handler: the gate rides with the BYOK/key gates (before appends,
beginTurn; record re-read after); the kick at the onFinish tail
(re-resolves engine fresh; silent no-op when engineless)
- events: compaction-changed {chatId, running} — running=true is the
client send-gate signal
- settings: compaction.thresholdTokens (factory 150k, floor 32k,
clamp-never-reject) resolved concrete in EffectiveSettings
- effective threshold = min(setting, contextWindow − 16k) over the live
catalog index
- overflow recovery needs no special path: the next turn's gate compacts
- 8 service pins (mutex, events order, chained spans, failure re-arm)

practice: the rarely-needed set — files, research, pdf, map readers (round 10 slice 1)
The practice registry widens beyond problem+conclude: read/ls/find/grep (the learner-filesystem set, always), research + pdf jobs (research honestly absent when no engine is live; demo/visual stay teach-only), and the prober's map readers behind the SAME settings gate as the prober's (graphToolsEnabled at the composition root). Base prompt carries the conditional doctrine: reach for them only when the situation genuinely requires — no propositions → look at the map; learner references a file → read it; load-bearing uncertainty → research it. Not toggle-filtered: problem/conclude are the session, these are exceptions. |

practice: pose-time target validation — names normalize to ids, unknowns rejected (round 9 slice 2)
problemTool takes the whole-graph node source (chat-handler passes graphStore.readNodes, read fresh per pose): prepareArguments silently normalizes name targets to canonical ids so the RECORD carries ids (the mastery trace groups on them); execute rejects unresolvable targets with a one-line invalidInputResult — no re-listing, the [id] proposition list already sits in the agent's context. Validation set is the whole graph, not the picks: pickless sessions and future graph-tools poses stay valid. Absent node source (tests) = no validation. |

practice hardening: weak-model argument heal + parked dismissals mid-turn
The GLM incident (2026-10-04): glm-5.3 sent mode as a JSON-string-encoded
enum ('"recall"') on 19 consecutive problem calls; TypeBox's error never
named the expected values, so the model re-emitted the identical payload
until the dev server was killed. And mid-turn the learner was trapped:
Esc's question/problem rungs only dismissed — the dismiss route 409'd
against the turn-owned record and nothing could stop the running turn.
- healEncodedArguments (practice.ts, the prepareArguments seam): a STRING
where the schema expects a literal union / boolean / null / number /
array is JSON.parse-d and kept when it satisfies the schema. Valid args
pass through untouched (same reference); unhealable values stay for
validation to reject honestly. Wired on BOTH problem and conclude.
- dismissal-park.ts: the dismiss route parks a mid-turn dismissal (202);
the turn's settle path (onFinish, after persistTurn, before endTurn —
the same ordering law as the record write itself) applies it against
the persisted record, only if the dismissed thing really is pending.
- confirmAbort: question/problem discard while busy now ALSO aborts the
in-flight turn; the dialog line says so (busy prop).
No error-result cap (owner ruling). 16 new pins (heal incl. pi-ai
validateToolArguments end-to-end; park registry, apply paths, the 202
route contract).

practice agent: problem + conclude tools, doctrine prompt, handler branch
- tools/practice.ts: problem (terminate pose; commitment hidden in args) and conclude (non-terminating; outcome/verdict/reveal/rung/missClass/ retest), gated by activeProblemOf — pose-while-active and conclude- with-nothing-active both return invalidInputResult. - prompts/practice/00-base.md (voice + accuracy + tool mechanics) and 10-doctrine.md (the owner's doctrine verbatim; one approved edit — §I material arrival generalized). Practice composes its own directory ALONE: no teaching base, no shared fragments. - createPracticeAgent (teacher-agent.ts); chat-handler branch — kind 'practice' builds the practitioner from turn 1 and skips extraction. - problemResult/concludeResult acks in tool-execute (conclude text single-sourced: CONCLUDE_ACK_TEXT). |

delete the batch practice-problems module (superseded by practice sessions)
Owner ruling 2026-10-04: the module is a sunk cost, retrievable from history if ever revisited. Removed: core practice contracts + pipeline helpers, the PracticeStore port + adapter + data dir path, server service + API routes (sets, clusters picker, practice aborts), the practice pages + dialog/exam/list UI, chain-table's Generate handoff, sidebar nav, activity-dock practice rows, and the partitioner/ problemGenerator/grader model roles (BACKGROUND_MODEL_ROLES 8 → 5). Survivors, moved to core/chains.ts (pure + browser-safe): ReasoningChain, chainsForSelection, formatChainLine — the chain table and graph emission still consume them. |

provider-events: raw provider stream recorder (LH_PROVIDER_EVENTS=1)
pi-ai 1.0's onProviderStreamEvent, at the layer our incident class lives (GLM arg truncation, DeepSeek id resets) — env-gated (owner choice: no app surface, off by default; raw events carry full prompts), one JSONL per chat under data/debug/provider-events/ with a 20MB cap and a run-start marker for record correlation. Wired at every agent construction: teacher/prober turns (AgentBuildOptions. chatId), jobs via LoopContext (researcher, demo-builder through runSubagent; visual-maker + pdf-reader through their streamOnce), and the extraction pipeline (extractor + auditor keyed by source id). practice deliberately unwired (sunk-cost module). |

tool-call id uniquifier: the Lacan fix (owner-approved 2026-10-04)
DeepSeek via OpenRouter returns tool-call ids that reset every response — a one-call-per-turn session names every call call_0. Everything keys on toolCallId (the fold's call↔result join, the pending gate, answer routing, the option-shuffle seed), so the Lacan session corrupted: the quiz answer overwrote the ask card, the ask question vanished, and the order scrambled. Record itself was always intact. - src/server/pi/call-ids.ts (new): ToolCallIdUniquifier at the wire boundary — colliding ids remint once (orig~2, ~3…), the same mints at settlement; tables key by message OBJECT IDENTITY (streaming messages carry no ids; the message_end object is reference-identical to the state object). History never rewrites; providers see paired ids, which is protocol-legal (pi synthesizes ids for providers that send none). - ui-stream: runPiTurn remaps events + settles through the uniquifier (spec.usedToolCallIds, seeded by chat-handler from the record). - view.ts: findToolPart scans newest-first — pre-fix duplicate-id records (the existing Lacan session) heal on next render. - tests: 9 unit pins (call-ids.test.ts) + the two-call_0 e2e (chat-flow): ask answered as ask, quiz as quiz, ids unique in the record. |

composer steering: the general steering machinery (owner arc 2026-10-03)
STEERING, NOT FOLLOW-UPS — pi-agent-core's two rails, used deliberately:
agent.steer() injects at the next response boundary INSIDE the live run
(one logical turn, the model changes course); followUp() would only extend
an ended run — not built. The same rail job markers already ride
(steeringMode 'all', the 2026-09-26 doctrine).
- POST /api/chats/[id]/steer: 404/400 honest guards; no live turn → 409
and the client silently falls back to a plain text send (the settle
race); live → steerLiveChat hands the message to the live agent's
steering queue AND parks it in the userSteers registry — the stranding
safety net. A steer stranded behind a question termination or abort
stays parked and rides the chat's NEXT run (handOffEligible), the same
deliver-or-requeue lifecycle as job markers. Reconciliation at settle:
delivered ids drop (reconcileUserSteers).
- Client: steer(text) queues + POSTs without flipping any turn state;
the drain's verbatim message events upsert the real user card by the
client-minted id (steer_<localid>) and the indicator fold drops the
line. canSend no longer gates on turnInFlight — Enter mid-turn steers;
Enter with an empty composer still stops; the square button stays Stop.
- The queued-steer indicator (owner spec): quiet one-liners above the
composer shell — right-aligned to where its corner rounding starts,
truncated with an ellipsis, fixed max width, ~half opacity, no
background, no container. Tunable later.
- Verified from pi-agent-core source: steering drains per completed turn
inside the loop; injected messages emit message_start/end verbatim;
finishTurn {action:'end'} (our question stopper) exits BEFORE the
steering poll — hence the registry.

parallel question gate: an answer that leaves a sibling dangling defers its wake (deepseek batch incident fix, owner 2026-10-03)
The incident: deepseek batched quiz + ask_user_question in one assistant message; the quiz executed first (sequential) and terminated the turn; the answer to the quiz IMMEDIATELY woke a reaction turn (fork-1 design assumed one dangling question max), the model complained about the unanswered ask, and the ask became permanently unanswerable — its toolResult could only append AFTER the intervening assistant message, a shape DeepSeek rejects. The gate: for answer inputs, if a question call still dangles after the append, persist write-ahead + emit record-changed + return the settled terminal — no turn. The dock advances to the sibling; the LAST answer fires the one reaction turn with every result adjacent to its calling message. Nothing else generates while a question dangles (job wakes wait, continuation folds refuse, the composer gates), so adjacency holds by construction. Also repaired the stranded session data (ask call stripped from the batch; backup at /tmp/chat_murkbeq2_backup.json). |

practice fix — creation is graph-domain: cluster picker, nodeIds-only API (owner ruling 2026-09-29)
Owner ruling: 'problem sets always take in nodes — graph objects' —
practice is graph-domain, not chat-domain. No session-created sets.
API: POST /api/practice/sets takes {nodeIds, params, title?} ONLY —
the chatId branch, UnknownChatError, and the any-provenance filter are
deleted; the selector is nodeIds (readNodes filtered to the selection,
unknown ids drop, empty live intersection → 400 empty_selection);
title optional from the UI (the picker's cluster label), dated default
stays. chatStore leaves the pipeline deps entirely (labels resolve
store-side in the clusters service).
GET /api/graph/clusters (new): the birth-session groups the graph view
renders — graphSnapshot's clusters verbatim (same ordering, same
MIN_CLUSTER_SIZE presentation filter), mapped to {key, kind
chat|notes, label (null when the naming record is gone — honest,
never guessed), nodeIds, nodeCount}; corrupt/empty graph → empty
list. GraphClusterGroup contract in core/contracts/graph.ts (client-
safe — the dialog imports it).
practice-dialog: session picker → cluster picker (rows show label +
proposition count, notes clusters marked); Create posts the cluster's
nodeIds + label as title + params. 400 empty-selection copy reworded
for the vanished-nodes edge ('Nothing practicable is left in that
cluster — the graph changed.'); 503 deep link unchanged. Preselected
mode gone — the dialog is the only creation entry for now (the graph-
view cluster entry comes later with free-form selection).
Sidebar: session right-click 'Practice this session's propositions'
removed (item + state + dialog wiring); the /practice nav row stays.
Tests: pipeline — chatId/any-provenance tests die, nodeIds selection
pins added (unknown-id filtering, dated-default title, title hint
rides, empty/vanished → EmptySelectionError); render — cluster picker
pins (label+count rows, notes kind, unlabeled cluster muted, empty
graph line), preselected pins removed; 16 render + 13 pipeline.
Docs: architecture.md §7 API+UI paragraph rewritten (graph-domain
ruling, /api/graph/clusters, cluster picker as the only entry, no
404-unknown-chat); README creation-flow line updated.
1130/1130, tsc 0, lint 0, build 0.

practice slice 4 — pipeline, registry, API, feed
src/agent/subagents/practice-pipeline.ts (sibling of practice.ts —
orchestration vs calls): createPracticePipeline(graphStore+practiceStore
+chatStore+PracticeModels). Fire-and-forget front doors returning
{set, done}: createProblemSet (refuse → resolve selection (chatId =
ANY-provenance membership per brief; nodeIds raw) → chains → snapshot →
createSet partitioning → registry row → runPartitioner → stubs land
(generating) → ONE generator per problem behind the process-wide
3-permit abort-aware semaphore (__lhPracticeSlots, extraction idiom) →
per-problem failure isolation → ready (errored problems included);
abortPractice (idempotent: controllers + 'Aborted' marks; dropped
grades keep answers, re-submittable); submitAnswers (ready-only,
already-graded rejects, one grading job per answer under the same
semaphore); deleteProblemSet (abort-first). Per-set write mutex on
globalThis (__lhPracticeLocks, audit-lock idiom); registry
__lhPracticeRuns one row per set per kind; boot sweep marks orphaned
partitioning/generating sets 'Interrupted (server restarted)'. Typed
errors: EmptySelection/UnknownChat/SetNotFound/SetNotReady/BadAnswers.
Usage folds stage logs into the registry row (v1: completion-folded).
src/server/practice.ts: thin service — strict params parsing, typed
error → response mapping (503 envelope family, 400/404/409), list/get.
Routes: POST+GET /api/practice/sets (202 {id}), GET+DELETE
/api/practice/sets/[id], POST /api/practice/sets/[id]/answers (202).
Composition root: chat-handler wires createPracticePipeline (engineFor
fresh + providerKeyMissing gate) exported as ; barrel re-
exports. Feed: observability activityFeed() += practice rows
(ActivityPractice); dock blobs (process 'practice', GraduationCap
icon, set-keyed abort); /api/activity/abort kind 'practice'.
tests/practice-pipeline.test.ts — 13 tests: end-to-end (stubs mid-
flight via gated generators, coverage complete), failure isolation,

fix: reasoning always renders above its message; dock drops delivered subagents at delivery
TWO owner-reported bugs from the live red-circle session (chat_muhpyoll_27305e23), both investigated to root cause first: 1. THINKING BLOCKS UNDER THE MESSAGE. GLM emits trailing reasoning tokens, so the persisted content lands [text, thinking] (4 of the 6 thinking-bearing messages from [21] on in that session) - and the view canon presented arrival order verbatim, rendering the reasoning UNDER its own message. Fix: projectView stable-partitions each assistant message - reasoning parts first (their own order kept), then text/tool parts. Owner ruling 2026-09-26: the reasoning belongs above, always. Covers live partials and settled records alike (one projection canon). NOT addressed (owner ruling): the plan_tools "missing" claim in the same session - wire-verified 11 tools incl. plan_init; GLM confabulation, no mitigation wanted. 2. DOCK CARDS LINGERING AFTER DELIVERY. /api/activity lists jobs with status "running", and the status flipped only in settleSteers at the DELIVERING TURN'S onFinish - so a subagent whose card was already visible in the transcript (marker injected mid-run) stayed in the background dock until the teacher finished teaching. Fix: flip the job at the moment the result reaches the learner - noteSteerVisible (jobs.ts) called from BOTH visibility seams: the marker's message_end wire event (live steer injection, ui-stream) and the write-ahead persist (the wake's input appends, chat-handler). finalizeJob is idempotent; settleSteers/runner-200 re-run it as a no-op, and the registry's delivery promise still settles exactly as before. Tests: 1001/1001 - view-canon hoist pin (trailing [text, think, call] projects reasoning-first; think-first unchanged), noteSteerVisible unit pin (flip at the seam, idempotent, handoff no-op), and the mid-run steering e2e now holds the turn open past the injection and pins the job flipping done at the marker's message_end WHILE the turn still streams. Live-verified read-only on the owner's server: the original session reloads with every reasoning trigger above its message. |

feat: Wave C pivot - steer markers, not follow-ups
Owner correction (2026-09-26, later): a real lesson is ONE continuous teach->quiz->teach run - there are no run-would-stop moments mid-lesson, and the run ends that DO exist are quiz stopper exits where delivery must not fire. Subagent results must land BETWEEN messages INSIDE the run, never splitting a toolCall from its toolResult. Vehicle 1 now hands markers to agent.steer() - pi's STEERING queue: the loop drains it at TURN BOUNDARIES (after a completed assistant message AND its tool results - the bonded pair survives injection) and again at RUN START (a continuation drains before its first LLM call), then CONTINUES the run with the marker in context. steeringMode "all" replaces followUpMode. registerLiveAgent moved BEFORE runPiTurn and now hands pending markers itself: the start poll drains the queue SYNCHRONOUSLY inside the runPiTurn call, so a later registration would miss it. A marker stranded by a quiz-terminated run therefore rides the ANSWER run's first LLM call - the native replacement for the old continuation coalescing. Settlement reconciliation, the idle wake, probe-handoff exclusion, and the registry-as-truth design are UNCHANGED; stranding is now exactly the stopper-exit case. Tests: jobs 45/45 (fakeAgent.steer; new pin - registration steers pending markers into the new run, parked wake never fires); chat-flow 24/24 (new e2e through the real composition - a gated mid-run turn, a marker delivered while the turn streams, record shape [call, result, MARKER, response] with the marker adjacent to the completed unit, the model SEES the marker in its next prompt, zero wakes); full suite 999/999, tsc/lint/build green. Live smoke (PORT=3004): research dispatched in the probe turn parked behind the dangling quiz; on the quiz answer the marker injected at the answer run's START poll - record [answer result, marker, teacher response], job flipped done/delivered at settlement, brief card rendered with its sources toggle. Plan doc: docs/PI-NATIVE-MIGRATION-PLAN.md gains the pivot section. Deferred (owner list): thinking blocks rendering after messages; vanishing tool-call output tokens. |

feat: Wave C - pi-native steer/follow-up delivery
Delivery now rides pi's OWN follow-up queue when a run is live, and a carry-everything idle wake otherwise. One registry, two vehicles; claimSteers and continuation coalescing are deleted (owner rulings, 2026-09-26: follow-ups only; one queue; the wake is the only appender). THE LIVE RUN (vehicle 1): the chat-handler registers the streaming turn's agent (registerLiveAgent, next to registerTurn); the pump hands every eligible queued marker to agent.followUp() - pi polls that queue when the run would otherwise stop, injects the markers (message_start/message_end on the live wire), and CONTINUES the same run. followUpMode "all" joins every handed marker in one continuation turn. The question stopper runs before the follow-up poll, so an open quiz is never overridden - a handed marker strands at settlement and waits (today's pacing). probe-handoffs never take this path (the handoff must START the teacher's run - a record-level branch). SETTLEMENT RECONCILIATION: settleSteers(chatId, persisted) at onFinish (after unregisterLiveAgent) resolves+flips entries the run delivered and returns stranded ones to pending - the registry stays the truth; the dead agent's queued copy is abandoned. This is what makes the handoff safe: pi owns no retry for a stranded follow-up. THE IDLE WAKE (vehicle 2): waitForIdle (unchanged gates) then ONE turn carrying EVERY pending marker as its input appends - dequeue-at-fire (the Wave B regression lesson: the wake run's own follow-up poll must never see its own cargo; a 409 pushes the cargo back and retries). CLIENT: applyWireEvent now upserts non-assistant messages by id, so in-run injected markers render live instead of dropping until settle. Tests: jobs 44/44 (live handoff, settlement stranding, handoff-waits, one-wake-carries-all); chat-flow 23/23 (the double-append pin drives the real pump through the new input); session-core 28/28 (custom-role wire appends). Full suite 997/997, tsc/lint/build green. Live smoke (PORT=3004): research job delivered mid-probe - parked behind the dangling questions exactly per semantics, landed once on the open gates, teacher folded the brief in and re-dispatched; the second (good) result rendered the full 10-source brief card and the lesson continued from it. No duplicate ids anywhere in the record. Known gap flagged to owner (NOT from this change): the server accepts malformed answer events via raw API (answers without the answers[] shape) and AnsweredCard then crashes the page render - surfaced by the smoke's scripted answers, repaired by hand in the scratch record. |

fix: pump wake turns double-appended their steer (Wave B regression)
A pump-fired wake turn carries its steer in the input appends, but the pump only shifts its queue entry AFTER the turn registers - so the handler's claimSteers popped that very steer too. The record-side steerDelivered filter checks the PRE-write-ahead snapshot and cannot see the carried copy: the marker persisted twice with the same steer_<jobId> id, two view messages shared one React key, and the client crashed on delivery (live: steer_job_muhlokbf_84e9373c). This exact bug was known and fixed 2026-09-18 (the old claimSteers received the incoming body messages and finalized-without-appending anything the request already carried). Wave B's turn-root rewrite kept only the record-side filter and lost the carried-side half. The fix restores the carried filter: a steer whose id the input already carries is claimed-and-finalized but never appended a second time. Regression pin in chat-flow.test.ts drives the REAL pump end to end (deliverJobResult with a real job record -> waitForIdle -> scripted wake turn) and asserts exactly one copy + the wake response. Two test lessons baked into comments: chatIdOf resolves a job steer's chat through the JOB STORE (a synthetic jobId with no record silently no-ops the pump), and deliverJobResult resolves at CLAIM time, not at turn completion (the record assertion waits for the wake response). The live-corrupted record (chat_muhlcltz) was deduped by hand. |

Wave D: native AgentEvent wire + client session rewrite (SDK purged)
Server: ui-stream.ts is verbatim pi AgentEvent passthrough (SSE data lines + [DONE]); only app-level events are the loop-level error and turn-settled terminal; onError carries raw provider text (owner ruling). Client: useChat + the AI-SDK transport replaced by components/session-core.ts (SessionModel: 409 identity-retry, optimistic c_ appends, absorbed() adoption, needsContinuation, shared consume for POST + reattach) and the session.ts hook; the golden-master grouping canon moved client-side into core/view.ts (projectView); scanners read the native record (phaseAt3Lh, danglingQuestionOf, graph toolParts, plan-blocks, runner, extraction). Coverage: the native message is the unit (fork 3) with the call+result inseparability bond rule; view-line-less messages (markers, error results) are invisible to coverage and never checkpointed. Deletes: chat-transport, projection, ui-message, their tests (ported to tests/session-core.test.ts), and the ai + @ai-sdk/react dependencies — the Vercel SDK is fully out of the tree. Wire pins in chat-flow rewritten onto the AgentEvent dialect (eventsOf parser). Gates: tsc clean, 994/994 tests, eslint clean, build green; live smoke on PORT=3004 (verbatim wire → native record). |

Wave B: the native message record — input events, projection, adapter death
The chat record is now pi-native agent history (LhMessage[]), the AI SDK's
UIMessage transcript contract is gone from the server, and every client turn
arrives as ONE explicit input event.
Core (new):
- src/core/native-messages.ts — the LhMessage taxonomy (user/assistant/
toolResult + lhMarker customs: verdict, probe-handoff, subagent-steer,
subagent-abort, plan-block), constructors, and toLlmMessages — the single
model-facing seam (convertToLlm): strips ids, flattens markers to user
text, drops UI-only plan-blocks, synthesizes INTERRUPTED results for
dangling aborted calls, never throws.
- src/core/projection.ts — projectNative: the one-way native → UIMessage
projection (consecutive assistant+toolResult runs group into one
assistant view message; toolResults attach backward by toolCallId;
markers project to data parts; plan-blocks splice after the last
successful plan_init). Every existing consumer reads through it.
- src/core/input-events.ts — the ChatInput union (text/answer/verdict/
continue), parseChatInput validation, and inputAppends (answer targets
the dangling question call or 400s; verdict = optional note user
message + native verdict marker).
Server:
- chat-handler.ts — the turn root takes {chatId, input}; write-ahead
persists input appends + claimed steers before the turn; claimSteers
coalesces the whole queue with the handler's steerDelivered filter as
the dedupe seam; teacher-vs-prober branch on hasProbeDone.
- turn-service.ts — persistTurn stamps ids, drops clean question
placeholder toolResults (the record ends at the unanswered call),
emits plan-block markers idempotently (plan-blocks.ts rewrite), and
persists abort partials.
- ui-stream.ts — PiTurnSpec takes the native base; the wire dialect is
unchanged. jobs.ts steers are native markers (steer_<jobId> dedup ids);
waitForIdle reads danglingQuestionOf. teacher-agent.ts wires
convertToLlm: toLlmMessages. record-adapter.ts DELETED wholesale.
- GET /api/chats/[id] serves messages: projectNative(record.messages).
Client:
- chat-transport.ts — the 409 retry is IDENTITY (re-POST the same event
body after the turn settles — the event was never persisted
pre-acceptance; the merge logic is gone). The transport consumes the
stashed input event via prepareSendMessagesRequest and throws loudly on
a missing stash.
- chat.tsx — every send call site stashes exactly one ChatInput event
(text, answer, verdict, continue) before invoking the SDK send.
Tests: full native migration (chat-flow rewritten to input events and
native record pins; jobs/extraction/demos/graph/usage/plan-blocks/
probe-done/reattach-transport converted; record-adapter.test.ts deleted;
chat-transport tests pin the identity retry). 982/982, typecheck, lint,
build all green.

Background turn runner: every turn is a server-side process, clients are views
Owner ruling 2026-09-25. runPiTurn executes a turn decoupled from any HTTP
response: an unbounded memory-only event log (finite by construction; the
30-min liveness TTL bounds the pathological case) plus a subscriber set.
The POST /api/chat stream and the new GET /api/chats/[id]/stream are both
subscribers — identical SSE dialect; late subscribers get FULL replay
(starting at the start chunk) then live until finish + [DONE]. A view
cancelling (reload, navigate) now detaches ONLY — never aborts the turn.
The remote kill is the abort channel: POST /api/activity/abort gains
kind: "turn" (id = chatId; not_running 409 like jobs); handle.abort sets
sawAbort + agent.abort(), every subscriber closes cleanly, the partial
persists through the usual settle (onFinish runs once, then endTurn,
then unregisterTurn LAST so a view that finds nothing finds the record
current). No running turn on reattach: the cheap terminal — one
{"type":"turn-settled"} event + [DONE] (settledTurnResponse).
The live smoke caught what the unit suite had masked: the agent_end
close() had been left behind in the restructure — ReferenceError every
turn, steered into the error path; fixed and pinned (clean turns must
never emit an error chunk; finishReason stop present).

Key-presence refusal at every gate: a pinned model is not enough
Owner-diagnosed: the turn gate checked only model coordinates, so a pinned slot whose provider key was deleted passed the gate and died mid-stream masked to 'An error occurred.' The key is now gated where the model is — by what would RUN (env-first keyValue truth, so an env-shadowed key passes). - core/settings.ts: the provider_key_missing envelope family (code, provider, slots, human line naming the provider from AUTH_PROVIDER_KEYS labels) + ProviderKeyMissingError + isProviderKeyRefusal matcher. - chat-handler turn gate: refuses 503 before beginTurn when the resolved conversation's provider key is gone (slots: [strong]). - Job runner: same check via an injected dep (agent layer cannot read the key store) — a keyless engine refuses the spawn through the existing failure-shape convention, no phantom run. - Extraction pipeline: refuseIfStagesUnready refuses BEFORE any batch (first offender: extractor before auditor); the trigger skips info- level, /api/graph/import surfaces the 503 envelope per file. - Tests: 8 new pins (turn gate both ways, runner refusal, pipeline first-offender + pass-through, envelope factory, matcher); the three turn-driving suites seed OPENROUTER_API_KEY like any real setup. - Doc fix: stale EXTRACTION.chunkTokens comment in the manual-extract route (left over from eed4b4e). Known residual (pre-existing, flagged for master): the manual extract route logs BOTH config refusals as console.error (fire-and-forget path); the coverage ledger keeps everything uncovered either way. |

Extraction-UX data layer: the chunk budget becomes a graph setting; the chat view gets a per-session coverage read
Owner-locked extraction-UX redesign (dispatch 2026-09-24), part 1 (data
layer; the UI chunk follows).
THRESHOLD -> SETTING
- config.ts's EXTRACTION.chunkTokens dies; the default moves into
FACTORY_SETTINGS.graph.extractionChunkTokens (4096, the old constant's
value). GraphSettings gains the optional field, Required at resolution
via the standard ?? FACTORY pattern — pre-redesign records resolve the
default cleanly.
- FLOOR 500 (the implementer's call, documented on the field): every run
pays the graph-carrying prompt overhead out of the write channel's
money — a smaller budget fires penny-batches that cost more per
extracted token than the content is worth. The sanitizer CLAMPS up
(bd68486 clamp-never-reject discipline: fractions floor, junk drops);
the settings PUT REJECTS below-floor with the rationale in the message.
No ceiling: a large budget just delays extraction — the user's stated
cost/thoroughness tradeoff, not a misconfiguration to police.
- The trigger (turn-service.triggerExtraction) takes the budget as a
parameter — chat-handler passes effective.graph.extractionChunkTokens,
the fresh per-turn read, same as every other gate.
- The pipeline's BATCH side threads through the same number:
ExtractionPipelineDeps gains an OPTIONAL getChunkTokens getter with the
factory default (Teacher's 24 test fixtures stay untouched; the two
call-site lines inside extraction.ts are the only cross-band edits,
flagged). chat-handler + backfill/import-notes wire the live
effectiveSettings — trigger and batches share one budget, always.
PER-SESSION COVERAGE READ
- sessionCoverage(chatId) (server/chats.ts): the chat view's ring-meter
block — totalMessages/coveredCount/uncoveredCount/coveredTokens/
uncoveredTokens (the same coverageOf derivation /api/graph/coverage
serves, scoped to one chat), running (chat-kind extraction registered
for this id), and lastFoldedAt (the chat's newest coverage row's fold
— a cheap single pass; null before any fold). GET /api/chats/[id]
carries it as coverage: {...}; unknown chat -> null (the route 404s
first).
- /api/graph/coverage (the all-sessions list) compiles untouched — the
per-session read is a scoping of it, not a supersession; the UI's
sidebar/ring chunk decides which surface it consumes.
Tests: factory/sanitizer pins (clamp-up, fraction-floor, junk-drop),
resolution pins (absent -> 4096, stored 2000 wins), settings-body pins
(valid/absent/fraction/below-floor 400/junk 400), sessionCoverage pins
(derived split, newest-fold scoping, cross-session isolation, running via
the registry, null on unknown chat). 893/893.

Wave 7 close-out: the embedding ledger seam dies; notes birth via mapping lines
Part 1 — the ledger + remnants interlude (master-dispatched, owner ruling 2026-09-23: nothing configures the graph beyond chat models): - The embedding ledger surface is gone: readEmbeddings/writeEmbeddings ports, the EmbeddingsLedger contract, EMBEDDINGS_FILE (config, store impls, graphRevision source list), and graph-deletion's vector-pruning step. On-disk data files stay untouched (inert history). - The extraction embedder seam dies wholesale: ExtractionPipelineDeps drops the embedder dep (chat-handler + backfill/import-notes stubs go with it), the 'embedding' phase leaves ExtractionPhase, the usage capture/persist helpers die, and stages.embedding leaves ExtractionRunUsage (historical records keep their shape — reads are lenient). Extraction is two stages again, like the local-embedder era. - Consumer-less remnants: latestQuizOutcomes + QUIZ_EVENT_KINDS, clusterContentId, matchClusterLabelings + Community + ClusterLabeling, the readClusterLabels/appendClusterLabel port seams + store impls + LEDGER_FILES.clusterLabels. NamingRunUsage/readNamingRuns STAY (standing ruling — the cost pill renders historical naming spend); clusterHue + MIN_CLUSTER_SIZE stay (live). - The 'labeler' role dies: BACKGROUND_MODEL_ROLES, ROLE_SLOT, ModelRole, the catalog pin projections, and the UI roster strings. RolePins keys shrink with the union. The notes birth fallback (owner-approved 2026-09-23, surfaced by the interlude's live smoke: production notes imports create provenance-EMPTY nodes (importNotes passes messages: null — the file's anchor is the mapping line), so the provenance-only birth rule left every imported file unclustered and invisible to the prober's session list, against the locked file-birth ruling. A provenance-empty node now births under its FIRST mapping line's chatId (ledger order); only notes-born nodes ever hit the fallback (chat nodes always carry provenance; a re-encountered node's link-append re-opens the provenance rule). Deletion-safe: mapping lines of deleted chats are stripped alongside their provenance. Live-verified on port 3004: a fresh notes import clusters under its src_ id with the file path as the label, end to end with no embedder. 845/845 tests, typecheck/lint/build green. EOF ) |

wave 7: the prober reads its map — graph-context injection dies whole
The owner's zero-configuration ruling (2026-09-23): nothing configures the graph beyond chat models. The prior-knowledge injection — its budget dial, its runner, its marker part, its dock/dispatch entries — is removed across all bands; the prober now reads the learner's persistent knowledge map on demand through two gated tools instead: - list_sessions: every birth session, names + kinds + counts + dates (graphSessionIndex, Platform's core seam) - list_propositions(session): what was born there + the session's own latest understanding level + that evaluation's date (graphSessionPropositions) — names/levels/dating ONLY, no statement text (owner ruling: the map's organization is the prober's business, its prose is not) Registered via createProberTools when chat-handler passes graphStore (the graphToolsEnabled gate decided server-side, per-turn fresh); the prober doctrine gains the map-review nudge at session start. Also: runner's JobKind special-casing collapses (KIND_ROLE/KIND_RUNNERS are plain records again), semantic-clusters.ts dies with its test, the embedder dep's doc tells the wave-7 stub story, and ports.ts's readClusterLabels/readNamingRuns surface stays untouched for Platform's ledger-port interlude. 848/848 tests, typecheck/lint/build green. |

Wave 7 chunk B: remove the embeddings machinery — the ladder collapses
The owner's wave-7 ruling: embeddings die entirely (git history is the
stash); clustering is birth-session derived (chunk A, 950ddfd), labels
are session names, and the prober's graph tools replace injection.
- settings: GraphSettings collapses to { enabled } — embedding,
embeddingModel, clustering, labeling all die. Migration story: stale
record keys are UNREAD and dropped by the sanitizer's reconstruction;
the next graph-section PUT (replace-whole) persists the collapsed
shape. The settings-panel GraphSection renders one master row.
- deleted: src/server/embeddings.ts (adapters, resolveEmbeddingPortFor,
embedNewNodes, embeddingPort, embeddingModelCatalog), the
GET /api/models/embeddings route, scripts/embed-graph.ts, tests for
all three, and the /api/models/embeddings picker surfaces in the UI.
- prices: EMBEDDING_PRICES overlay + callCost fallback die. cost-summary:
the embedding stage fold dies — back to three stages (extraction/
audit/naming) per the owner ruling; historical stages.embedding spend
in old run records is simply not displayed.
- ports: EmbeddingPort/EmbeddingResult/EmbeddingTask die. The embeddings
LEDGER surface (readEmbeddings/writeEmbeddings + EmbeddingsLedger +
EMBEDDINGS_FILE + graph-deletion's vector pruning) STAYS — inert data,
kept only so graph-context.ts compiles until Teacher's pass removes
it; the seam dies in the follow-up interlude.
- chat-handler (approved cross-lane unwiring, wave-6 precedent): the
extraction pipeline's embedder becomes a documented no-op (nothing
embedded, nothing spent, ledger untouched) until Teacher's pass
removes the phase; the graph-context injection dispatch gate, the
graphContext deps wiring, the setContextRespawn seam, and
turn-service's triggerGraphContext are gone — injection is dead
code pending Teacher's file deletions.
- scripts: backfill-graph/import-notes pass the same no-op embedder;
replay-layout derives clusters from birthSessionPartition (the same
partition the real settle uses) instead of the embeddings ledger.
- settings-body: parseGraphSettingsBody reads the master switch only —
old-shape keys in a body are ignored, not rejected; bad shapes 400.
- next.config: the @huggingface tracing-exclusion guards die with the
last reference.
Cross-lane flags: extraction.ts/graph-context.ts keep stale embed
comments + the embed phase until Teacher's full pass (their parallel
interlude owns those files — zero overlap kept by design);
semantic-clusters.ts + its test stay one more round (extraction.test.ts,
Teacher's file, still imports it — they delete it with the namer cases);
ChatSettings.graphContextTokens + the graph-context-control UI stay
until Teacher+UI.
Gates: tsc clean, eslint clean, 885/885 tests, build compiles.
Live-verified on the port-3004 dev tree: PUT /api/settings/graph with
dead keys collapses on write, bad shapes 400, GET reads {enabled: true},
/api/models/embeddings 404s.

BYOK provider embeddings (wave 6 chunk B): kill local transformers
Replace the @huggingface/transformers local embedder (~316MB ONNX cache) with an EmbeddingPort seam: graph.embeddingModel (nullable "provider:id" slug) selects an OpenRouter/OpenAI/Gemini adapter, resolved fresh per call from settings + the auth store so key rotations land immediately. - src/server/embeddings.ts rewritten: slug grammar, injected-fetch adapters (OpenRouter input_type, Gemini taskType batching, OpenAI index-ordered rows), honest resolution (null = skip-with-info, set model with missing key = honest error), embedNewNodes with model-change re-embed wipe + ghost pruning + usage steps, federated catalog (OpenRouter /api/v1/embeddings/models — VERIFIED live, the inverse path 404s; OpenAI text-embedding- filter; Gemini embedContent filter). - GET /api/models/embeddings: federated catalog, empty when no keys. - Extraction tail records stages.embedding usage into the run's money channel; EMBEDDING_PRICES overlay in core/prices.ts (outside the sync-generated block), callCost falls back to it; cost-summary folds the fourth stage; graph-context injection resolves its embedder per run, fails honestly when unconfigured, records query tokens. - Settings: GraphSettings.embeddingModel (null factory), section parser validates slug shape (id may contain colons — OpenRouter :free suffixes, live catalog fact). - Removal: @huggingface/transformers uninstalled, PATHS.modelCache and onnx tracing entries deleted, @huggingface tracing-excludes guard added, stale sharp/libvips comments updated to historical. Live-verified on port 3004: catalog federates 36 rows (33 OpenRouter + 3 OpenAI), embedNewNodes embedded 10 nodes via the free liquid/lfm-2.5 model (dim 1024, 435 prompt tokens, 1 call, $0), settings PUT rejects bad slugs with 400. Gates: typecheck, lint, 895/895 tests, build. |

feat(models): BYOK all the way down — factory pins deleted, per-need refusal gates
Owner decision 2026-09-22: 'it doesn't make sense to have any default
model configured anywhere; the application is bring your own keys.'
config.ts: MODELS deleted; ModelRole becomes an explicit 9-role union;
DEFAULT_THINKING_ORDER (medium, low, high, minimal, xhigh, max) bakes
the unset-level default — first entry the model supports; explicitly
set levels keep pi's native nearest-clamp.
core/settings-resolution: the factory layer dissolves — the chain is
role override → slot → NOTHING. resolveSettings(record) takes no
factory. Empty chains resolve to null/undefined; a thinkingLevel-only
slot is inert (stored, never run). resolveConversationSpec: chat.model
override over the strong slot, null when both empty. resolveRoleSpec
spans all nine roles for the job/extraction engines.
Refusal envelope (core/settings.ts): modelsNotConfigured(missing) —
{error, code: 'models_not_configured', missing: [slot tiers]} +
ModelsNotConfiguredError with .envelope. Per-need gates, each honest:
- chat-handler: universal turn gate (new + continuing turns) returns
503 before beginTurn — no liveness, no write-ahead persist, no graph
trigger before the gate fires.
- runner.runJob: unresolvable engine lands the job as error with the
envelope wording; no phantom loop, no result steer.
- extraction: refuseIfStagesUnconfigured throws before any stage
(turn-service info-skips so coverage retries next turn; the import
route surfaces per-file code+missing); labeler-less runs skip
cluster naming with a console line and still merge.
Write side: slot entries must carry a model — level-only slot writes
are 400s (absent slot key = clear). piEngineForSpec resolves unset
thinking levels via DEFAULT_THINKING_ORDER; piEngineFor now throws
honestly; thinkingLevelFor/modelIdFor deleted; teacher-agent, pi-run,
visual-maker, pdf-reader all read engine.level.
model-catalog: defaults/slots/rolePins null when the chain is empty
(contracts nullable) — no phantom ids in payloads. Stores drop
MODEL_PINS entirely.
Tests: pin-leaners converted to explicit injection (per-chat model
pins on scripted chats — exactly what the setup flow writes; faux
engines for agent-construction tests). New coverage: the 503 gate
envelope, the runner refusal, the extraction refusal + labeler skip.
Gates: typecheck, lint, 815/815, build.

fix(tools): wire the searchAvailable gate + research/pdf in the probe phase
Fix wave (2026-09-20), two owner-approved fixes: Fix 1 — the searchAvailable gate was dead code on the live wiring path: createTeacherTools RECEIVED ctx.searchAvailable but dropped it when building the inner JobToolContext, so jobTools' research gate always took its ?? true default (jobTools-direct tests passed; the production path never saw the signal). Threaded through — the gate now reads the live server signal on the teacher registry too. Fix 2 — the prober registry gains the research + pdf dispatch tools (owner ruling, 2026-09-20): these two are phase-omnipresent — the prober can verify facts or read learner PDFs while assessing. demo/visual stay teach-phase-only (they need the lesson's plan context). Same gating as the teacher side: toggle-filtered, research subject to the search gate (honestly absent when no engine is live — the prober's dispatch closes over the SAME jobTools builder, one gate, one semantics). probe_done stays always-on-by-construction; the learner-fs set untouched. - ProberToolContext (extends ProbeDoneContext with the job wiring); createProberAgent takes it; chat-handler injects jobStore + spawn + searchAvailable into the prober ctx. - TeacherToolContext.spawn's stale input union fixed (PdfInput was missing from the TYPE — runtime already passed it). - Tests: the threaded-gate describe in web-search.test.ts pins the LIVE factory path both ways (teacher + prober); question-tools' registry key-sets gain research/pdf; the prober toggle test pins the research:false path. Gates: typecheck, 807/807 tests, lint, build — all green. |

feat(extraction): stage engines resolve the slot chain — engineFor on the pipeline
Chunk B, item 3 of the search port + slots wave (2026-09-20): the flagged gap closed — ExtractionModels deps were engine VALUES, keeping extractor/auditor/labeler config-pin-bound while the job runner went slot-native. The pipeline now takes the runner's exact treatment: - ExtractionPipelineDeps.engineFor: (role) => PiEngine — resolved FRESH per stage call, so a settings PUT between stages lands. Direct test values (extractor/auditor/labeler) remain the priority seam, checked FIRST; absent values fall to the chain; absent chain → config pins (unchanged). - All six stage call sites (chat + notes extract/audit, the cluster namer x2) resolve through stageEngine(role, direct). - chat-handler's extraction composition injects the full chain — piEngineForSpec(resolveRoleSpec(role, readSettings(), MODEL_PINS)) — same wiring as the job runner. Chunk B, item 4 (session-level slot-anchored model picks): VERIFIED already complete from Platform's model-slots wave — the conversation engine chain (chat-handler) anchors on effective.models.strong, the picker's default surface (catalogDefaultsFor) falls back to strong, both pinned in tests. No phase split (user decision, 2026-09-20). Capability-filtered pickers live in the settings UI (main 343be10). Tests: engineFor fills the stages end-to-end (both propositions merged through the chain, consulted in pipeline order) + the direct-value priority pin (engineFor that throws when consulted). Gates: typecheck, 795/795 tests, lint, build — all green. |

feat(search): web_search onto the injected port — Google CSE retired, research honestly disabled
Chunk A of the search port wave (2026-09-20), per master's assignment: - web.ts: the Google Custom Search backend is gone — web_search now runs on the core search port (SearchProvider), injected as a dependency (import law: the tool never imports server code). createWebTools(search) resolves the LIVE provider fresh per call; null = the honest unavailability string (no silent fallback, owner decision). web_fetch unchanged (needs no engine). - runner: JobRunnerDeps.searchProvider — the server composition threaded into the researcher; jobs already in flight when a key disappears still fail honestly through the same seam, never crash. - jobTools: the research dispatch tool DROPS from the teacher's registry when ctx.searchAvailable() is false (owner decision: registry-level drop — the model never sees the tool, no doomed dispatch, no error card). Absent seam = available (tests). chat-handler injects server/searchAvailable + searchProvider. - tests: stubFetch (the Google wire stub) retired; jobs.test.ts threads a recording stub provider through all four research runners and asserts the scripted query hit the port; new web-search.test.ts covers the factory contract (null → honest string, hits, error strings, fresh resolution, web_fetch independence) + the registry drop matrix. Gates: typecheck, 793/793 tests, lint, build — all green. |

feat(models): strong/cheap/vision model slots + multi-provider engine federation
Model slots wave (2026-09-20), chunk B:
- settings: new `models` section {strong, cheap, vision} slots (each
field independent, same shape as a role override); ROLE_SLOT maps all
nine roles to tiers (strong=prober+teacher, cheap=researcher/
demoBuilder/extractor/auditor/labeler, vision=visualMaker+pdfReader);
resolution chain per role: override → slot → factory pin.
- config: ModelSpec gains provider (all pins openrouter, the BYOK
default); MODEL_PINS in stores.ts now spans all nine roles (the strong
slot's factory rep IS the prober pin).
- engine: piModels() registers EVERY builtin provider catalog;
piEngineForSpec(resolved spec) is the new engine factory (pi-ai
resolves per-provider keys from env itself); piEngineFor stays as the
config-pin fallback. chat-handler resolves the conversation chain
(chat override → strong slot → pin) and injects engineFor into the job
runner, closing the old gap where per-role overrides never reached
job engines.
- /api/models: models federate ONLY keyed providers (providers surface
with keyPresent, env-wins, fresh per call); slots (resolved tier pins)
join rolePins; catalogDefaultsFor inherits the strong slot; the models
settings section gets the same catalog gate as chat.
- pricing: PRICES/CONTEXT_LIMITS uniformly keyed provider:id
(regenerated from ALL pi-ai catalogs, 1354 keys); usage stamps
(TurnUsage, JobUsage, extraction stages) switch to provider:id —
owner decision: no legacy compat, old stamps render unpriced.

feat(prompts): composeInstructions honors overrides — the P2 segment reconciliation
The other half-wired seam: Platform's settings 'agent.prompts' switches had no consumer in the agent layer, and their effectivePromptSegments mirrored the PRE-sources-v1 loader — the shared/ fragments dir (the learner-files doctrine) was invisible to it, so a naive delegation would have silently dropped the segment from both agents' prompts. - src/core/prompt-segments.ts (NEW, pure): the mirror-layout path grammar + segment types, defined exactly once; core stays zero-IO. - src/agent/prompt-segments.ts (NEW, the CANONICAL discovery): base + shared/ + per-agent fragments, override resolution, allSegmentPaths. Composition is an agent concern; the agent layer reads its own tree (the architecture law pins agent and store apart — the first direct refactor attempt tripped the enforced import/no-restricted-paths zone, hence the three-layer split). - src/store/prompt-overrides.ts: slimmed to the override-file CRUD behind the core port; shares the core grammar. Its doc no longer claims to be the canonical mirror. - teacher-agent: composeInstructions(kind, switches?) composes through effectivePromptSegments — a segment whose switch is ON and whose override file exists composes the override text. Switches-less calls use the cached pure-source composition (byte-identical to the old loader, pinned by test); AgentBuildOptions.promptSwitches threads effective.agent.prompts per turn, composing fresh so override-file writes flip the very next turn. - server barrel: re-exports the agent module's resolution for the settings routes (server→agent, the lawful direction). Tests: byte-identical source pin, override swap-in (on/off/file-absent), shared/ overridability in both agents, agent-construction threading, updated segment-list pins with shared/ in composition order. This file keeps owning PROMPTS_OVERRIDE_DIR (parallel-test discipline). Gates: 671/671, typecheck, lint, build. |

feat(tools): the P2 toggle bridge — toolToggles first-class, definitive vocabulary
Reconciliation of the diverged tool-toggles seam (2026-09-19, master's P2): Platform injected the resolved delta as an ad-hoc intersection on AgentBuildOptions while the factories' enabled? param sat unread — the seam was inert on both sides. - teacher-agent: AgentBuildOptions gains toolToggles?: EnabledTools; both constructors thread it to the factories (createTeacherTools / createProberTools). An explicitly injected opts.tools registry is never filtered — the caller owns it. - Vocabulary ADJUDICATED with the user (2026-09-19): TOGGLEABLE_TOOLS is the definitive list — the job tools only (research/demo/visual/pdf). quiz/ask_user_question stay always-on forever (the prober's flow is graded-quiz brackets -> probe_done; quiz-off collapses assessment and teaching doctrine is built on graded verification — the wedge danger); the learner-fs set, plan tools, and probe_done also always-on. - settings-body (write side): unknown tool keys reject with 400 + the supported list, mirroring the prompt-switch validation; the read-side sanitizer stays lenient for forward-compat. - chat-handler: the intersection is gone (field now first-class) and the seam comment states the adjudicated vocabulary. Gates: typecheck, 28 new/updated tests green (tool-toggles-bridge, question-tools, settings-body), chat-flow + settings suites green. |

fix: wake-turn steer delivered twice — claimSteers re-claimed the steer the pump's request already carried
The wake pump fires its turn with the steer INSIDE the request body but dequeues the queue entry only after the turn returns 200 — so the entry is still queued when the handler claims. The record doesn't carry the steer yet (write-ahead persist hasn't run), so claimSteers claimed it a SECOND time and the handler appended it: outgoing = [...body, ...claimed] held two copies of the same deterministic steer id, and the write-ahead persist saved that for the whole wake turn. The client's adoption poll rendered both -> React duplicate-key warning (steer_ctx_<chatId>). withMessageIds deduped only at onFinish, so the final record looked clean. Fix: claimSteers(chatId, incoming) — a queued steer whose id is already in the turn's incoming list is being delivered BY this very turn: finalized and resolved, never appended again. |

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). |

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.

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. |

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. |

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. |

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. |
