The Accept/Decline verdict gate is gone (owner ruling 2026-09-26):
presenting the plan ends the teacher's turn; the learner's next message
is a natural reply. Teaching begins at the first quiz call tagged with a
nodeId (probe quizzes carry none) — both folds (view phaseAt3, native
phaseAt3Lh) advance on the call itself, and the teach divider renders
before that whole assistant block. No backwards compat: verdict markers,
the verdict input event, optimistic appends, composer buttons, and
projection all deleted; prompts and docs rewritten to the natural flow.
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.
Live-driven via the owner's dev server (browser tools), reproduced on
/chat/new: send fires, optimistic appends, POST never happens, and the
page shows the frozen empty state. Three compounding defects:
1. session-core: default fetch stored UNBOUND — the browser's native
fetch requires this === Window, so every call threw 'Illegal
invocation' and the POST /api/chat never fired. Node's undici has no
receiver discipline, which is why 994/994 tests passed while the app
was dead. Now defaulted through a receiver-preserving wrapper; pinned
by a strict-this regression test (the browser's semantics simulated.
2. session.ts: state memo keyed on [model, forceRender] — the reducer
dispatch is STABLE by contract, so the memo computed once per mount:
no optimistic bubble, no stream events, no error banner. The view was
frozen at first render. Rekeyed on a version counter bumped by the
model's onChange.
3. view.ts: turn_end carries the clean 'Question posed' placeholder as
a toolResult message (details: null) — applyResult flipped the quiz
part to output-available with a null output and AnsweredCard crashed
on answer.dismissed (killed the whole page render). Fork 2 now holds
on the message-attachment path too: clean question results with null
details are ignored; the AnsweredCard renders only the learner's real
answer. Regression pin extended in session-core.test.ts.
Verified live end to end: new session → text send → probe questions in
the dock → ask answer → graded ✓ quiz card with explanation → reload
renders the full transcript from the native record with the pending
question intact.

)
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).
