chains-primary: stored chains replace typed edges; edges become a derived view
Owner rulings 2026-09-30: reasoning chains are the stored truth; the graph canvas renders a lossy derived image. No migration, no backcompat — old graph data was wiped. - contracts: GraphChain (arg_-minted id, premises, conclusion) replaces typed edges; GraphEdge survives only as the untyped derived arrow; GraphSnapshot carries stored chains; supports edges retired entirely - store: chains.jsonl ledger (edges.jsonl purged at load alongside legacy events.jsonl); readChains/appendChain seam; merge dedupes by (sorted premises, conclusion), re-assertions append under the same arg_ id - core: deriveView mints implication nodes (name ⟹, statement via formatChainLine) plus premise→imp→conclusion arrows; clusters stay proposition-only (birthSessionPartition); chainsForSelection now groups STORED chains (chain rides iff every member selected) — independent arguments for one conclusion never union; chainsToGraph/chainsToEdges die - extraction: extractor submits chains natively (expandFindings deleted); auditor receives propositions only; supports fan-out gone - deletion: full death of a proposition kills every referencing chain; arg_-prefixed node deletes kill that chain; chainsRemoved stats - UI: every arrow renders the ⟹ double shaft; supports toggle + thickness slider and detail-card edge sections deleted (card keeps name + proposition); chain table + practice pipeline read stored chains - tests: 1188 green across the new seams |

practice: the learner's creation note — optional free-form input carried to partitioner + generators (owner, 2026-09-29)
- dialog: optional 'Anything else?' textarea (typing-only, 2000-char mirror) - API: body gains note? — trimmed, whitespace-only omitted, hard 400 over 2000 - pipeline: note persisted on the set and threaded to both agent stages - agents: THE LEARNER'S NOTE prompt block (present only when set) + the weighed-never-owed stance pinned in both doctrines - fix en route: doubled THE PARAMETERS heading in both prompts since slice 3 (renderParams owns the heading; the literal blocks removed) |

practice restructure — per-problem jobs + ONE shared background-LLM pool (owner ruling 2026-09-29)
Rulings: each problem generation is its own visible dock job (the extraction per-chunk pattern), and practice shares extraction's semaphore — one process-wide 3-permit pool for ALL background LLM jobs; total background LLM concurrency bounded at 3. A. SHARED POOL: new src/agent/subagents/bg-llm-semaphore.ts — globalThis __lhLlmSlots, PERMIT_COUNT 3 (the ruling), the fresh-take/handed-off-permit deadlock discipline preserved for BOTH callers. extraction.ts's withExtractSlot is now a thin wrapper (job-row signal → withBgLlmSlot); __lhExtractSlots and __lhPracticeSlots both die. The partitioner now acquires a permit too (it's a background LLM job — it didn't before). B. REGISTRY ROWS: the aggregate setId:generation / setId:grading rows are replaced by setId:partition (phase partitioning, label 'Partitioning — title'), setId:gen:problemId (queued→generating, 'Problem i/N — title'), setId:grade:problemId (queued→grading, 'Grading i/N — title'). Each row carries its OWN abort controller and its OWN usage (one PracticeStepLog per row — the aggregate partitioner/generator/grader folding dies). Row key = feed id = abort key (the dock dup-key law). C. ABORT SEMANTICS: abortPracticeRow(key) routes by shape — gen row: THAT problem only (error 'Aborted', siblings continue, set settles ready with one errored problem); partition row: the whole run; grade row: that grade drops (answer kept, re-submittable). abortPractice(setId) composes from row aborts + the synchronous persisted marks (a set-abort's verdict stands before the settles re-read it — the settle step keeps an existing error status). /api/activity/abort kind practice now takes the ROW key (charset admits ':'). D. FEED + DOCK: ActivityPractice/FeedPractice carry per-row identity (id = row key, problemIndex/problemTotal); dock blobs render per row, labels carry the i/N; the aggregate row is gone. E. Boot sweep unchanged at set grain; the live-row check is now a key-prefix scan (any live row of the set protects it). The updatedAt heartbeat covers the new row scheme as-is. Tests (20 in the pipeline suite): per-problem row shape/uniqueness/ i-N labels (partition row frozen behind a gated partitioner; per-row usage ISOLATION pin — b's log never shows on c's row); abort-one-gen (sibling completes, set ready with one errored problem); partition- row abort; queued grade-row abort (dead-ticket path: answer kept, re-submittable, sibling lands); shared-pool identity + contention (practice queues behind extraction-style holders); registry/dock feed mapping. Test isolation hardened: unique per-store set ids, afterEach registry/lock/pool reset (a timed-out test can no longer poison the rest). architecture.md: jobs-pattern paragraph rewritten (per-problem rows, shared pool, abort routing). 1149/1149, tsc 0, lint 0, build 0. |

practice bug fix — the boot sweep stamped a LIVE run (owner live test 2026-09-29)
Owner report: created a set, 'Interrupted (server restarted)' showed on list + set views, generation proceeded and overwrote it. The sweep's 'generating + no registry row' test had a false-positive mode: it ran at EVERY pipeline instantiation, and an instance could evaluate against a registry whose fresh row it couldn't observe. Three guards, per ruling: 1. HEARTBEAT: ProblemSet.updatedAt? (contract + doc) — bumped on every store write; createSet stamps it = createdAt; saveSet re-stamps (validator tolerates absence for legacy rows). 2. ONCE PER PROCESS: the sweep guards on globalThis .__lhPracticeSweepDone — no instance re-evaluates after the process's first sweep. 3. GRACE WINDOW: only sets whose heartbeat (updatedAt ?? createdAt) is older than 120s are stamped. A live run saves at every phase/ problem transition, so it is structurally unreachable; a true orphan is minutes stale at next boot. One [practice <id>] log line per stamped set (the extraction/jobs console.error idiom). Tests: stale orphan stamped; FRESH generating set untouched (grace); once-guard (second factory instantiation never re-sweeps); live-row protection re-armed via resetSweep() test seam; store pins for updatedAt birth-stamp + re-stamp + legacy tolerance. Architecture.md sweep sentence updated (once-per-process + grace semantics). 1142/1142, tsc 0, lint 0, build 0. |

practice — discretized parameter axes: named levels, never a number (owner-approved 2026-09-29)
Contracts: LadderRung 0-4, CueDistance 0-2, Presentation theory|
application; PracticeParams carries the three named levels. Doc
comments hold the three definition tables verbatim (rung names +
definitions from the ladder doctrine; cue levels; presentation
levels).
Core: LADDER_RUNGS/CUE_LEVELS/PRESENTATIONS tables in src/core/
practice.ts (definitions verbatim) — ONE source spoken by the agents'
prompts, the dialog's stepped controls, and the exam header; core
barrel re-exports practice.ts (pure domain, browser-safe).
Agents: Part I's ladder intro now 'five rungs, numbered; the request
arrives as a rung' with bullets numbered 0-4 (definitions untouched);
Part III's parameters block replaced with the named-level doctrine
(rung = exact class, no continuum; cue counts lesson examples AND
previous problems' situations; presentation dresses, never changes);
partitioner's RESPECT THE PARAMETERS replaced (low rungs = many small
assignments, high = larger; far cue makes confusables-together MORE
important; presentation does not shape the partition). renderParams
outputs the exact named-level block. Anchor/0..1 language swept dead.
Service + store: strict union validation — floats between levels,
out-of-range, wrong strings, legacy dial shapes all 400 at the API
and fail isProblemSet (legacy sets skipped from lists; no migration —
data/practice is disposable scratch, owner wipes before testing).
UI: dialog = 5-detent ladder slider + 3-detent cue slider (each shows
the level NAME + one-line definition) + Theory|Application segmented
toggle; defaults rung 2 / cue 1 / theory; Create posts the new shape.
Exam header gains the levels line ('Direct exercise · Adjacent
context · Theory').
Tests: renderParams exact-block pin; strict-validation pins (new
tests/practice-service.test.ts — bad unions 400, legacy shape 400);
store pins (legacy floats + 2.5 rung fail); render pins (detents +
names + definitions, defaults, detent-swap, toggle active segment,
levels line); every params fixture moved off floats. 1138/1138, tsc
0, lint 0, build 0.
Docs: architecture.md — discretization paragraph (compact tables,
named-level invocation, defaults, one-table source), UI mentions;
README axes sentence.

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.

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,
3-permit semaphore pin, abort mid-generation, registry shape pins,
refusal-before-create, chatId any-provenance selection, typed errors,
answers→grades land + graded rejects, boot sweep (orphan + live-row),
delete. 1114/1114, tsc 0, lint 0, build 0.
