- Arrows into not-yet-visited nodes are grayed out like the nodes
(stroke-border line + a fill-border copy of the arrowhead); the
in-chat block stays all-white.
- The yellow glow is static — the pulse is gone (owner).
- Smaller blur: stdDeviation 7 → 5, glow rect margin 10 → 8.
- The glow clipped at the frame on narrow graphs: its visible reach
(GLOW_MARGIN + 3·GLOW_BLUR = 23 units) far exceeded GRAPH_PAD (8).
Surfaces that show the glow now pad by GLOW_REACH — the popup's
viewBox AND its fit box both use POPUP_PAD = GLOW_REACH, so the blur
never clips; the monochrome in-chat block stays tight at GRAPH_PAD.
Look (rectangular, white language — owner spec):
- Boxes: no corner rounding (rx dropped everywhere).
- Visited: fill-none, white stroke, white text. Upcoming: today's gray
(fill-card, border stroke, muted text) — kept per owner. Current:
white stroke/text + a faint yellow highlight — a blurred yellow fill
(feGaussianBlur) that bleeds out over the node's edges, still breathing.
- Edges + interim arrowhead: white (marker swaps to the owner's SVG when
it lands: right-pointing, solid fill, tight viewBox, tip at right edge).
- The IN-CHAT plan block renders monochrome — every node white, no
status language, no glow; the popup/plan-window show the progression.
Popup entrance fix: the transition from round 3 animated the first fit
(graph flew in from the top-left zoom:1 state). The transition now stays
off until the first fit has been applied — the popup paints settled.
In-chat full plan block:
- TEXT_CAP_SCALE (16.5/12.5): node text renders at text-xs in svg units;
the block now carries maxWidth = extent × cap + mx-auto, so it still
fills the column whenever the column is narrower than the cap, but
never scales node text past the chat prose size (--lh-prose-size).
- GRAPH_PAD (8 svg units) around the full-extent viewBox: centered
strokes (half outside the geometry) and the −4 glow halo were clipping
at the frame edges — the padded origin (-8,-8) keeps all ink visible.
Only the full-extent render pads; the plan window's override viewport
and the popup's fit margins are untouched.
Test pins updated: mx-auto + max-width:232.32px + viewBox='-8 -8 176 152'.
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).
- components/plan-block.tsx: hand-built SVG (user decision) — deterministic
layered layout (Kahn topo + longest-path depth, rows centered, authoring
tie-break), bezier edges, the retired panel's status color language.
- PlanBlock renders data-plan-block parts AS CARRIED (frozen snapshots,
never re-derived): kind full = borderless, viewBox = layout extent so
nodes hug the column edges, natural height; kind neighborhood = own
small labeled 'Plan fragment' container with the current node glowing
(pulsing primary halo).
- PlanPopup: full-screen overlay with the LIVE plan — latest tree from the
transcript, statuses derived at click time via derivePlanStatuses
(contracts/plan.ts). Esc / backdrop / X close; drag pan, wheel
zoom-to-cursor, zoom buttons; fit-floor semantics harvested from the
retired tree panel (zoom floor = the fit, pan locks at it).
- chat.tsx: data-plan-block case in the part switch + popup mount.
- src/core/ui-message.ts: TeacherUIDataParts gains "plan-block": PlanBlockData
(additive, type-only — lane touch flagged to master).
- tests/render-plan-block.test.tsx: pure layout (layering, centering,
dangling-edge tolerance), wrap, frozen-snapshot render, live derivation.
