amosblomqvist 88eb4b2ec0 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).

amosblomqvist f39e1b4294 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.

amosblomqvist 27c5d9df19 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.

amosblomqvist 4001c3465b Graph view: unique pill keys for chunk jobs (second duplicate-key consumer)
The graph page's pipeline pills keyed rows by run.chatId — the source id,
shared by every chunk job of a fan-out (the dock got the same fix in
8f66f47; this consumer was missed). /api/graph/status rows now carry an
id (the registry job key: source id, or 'src#i'), and the pills key by
it. chatId stays the SOURCE id — the reveal refetch and per-run cost
refresh track chatId SETS, which dedupe naturally and fire when the
source's LAST row leaves the feed.

amosblomqvist d047e7b2dc Per-chunk jobs: parallel extracts under a 3-slot semaphore, serialized audits (owner 2026-09-28)
Every notes chunk and chat coverage batch is its own job — registry row,
usage record, failure domain. Extracts fan out process-wide behind a
3-permit extract semaphore on globalThis (new 'queued' phase); audits and
merges stay serialized behind the existing FIFO gate ('waiting'), so each
auditor explores the graph after every earlier job's merge.

- ExtractionPhase gains 'queued'; RunningExtraction gains part {i,n};
  the feed shows one row per job with a '· i/N' suffix (status route)
- abortExtraction is source-wide: every job of a fan-out dies together;
  merged jobs keep their coverage checkpoints
- failure isolation at the fan-out (Promise.allSettled + aggregation):
  a failed chunk no longer kills its siblings — the run returns what
  actually merged; job-level aborts log, pre-fan-out errors still throw
- usage ledgers: one record per job (source-keyed), failed jobs bill
  their partial spend
- runJob/aggregateJobs helpers; setPhase/recordStep/extract/audit/
  notesExtract key the registry by jobKey (src#i) — notesExtract's
  signal lookup was the one real bug the new tests caught (source-id
  lookup meant fan-out aborts never reached the model call)
- semaphore is handoff-correct (fresh takes increment; handed-off
  permits don't double-count — an inflated counter deadlocks at 3)
- tests: isolation pins rewritten (stage failure now resolves zeros),
  single-flight/registry tails updated, per-job usage counts, and a new
  describe pinning the fan-out: 3 extracting + 5 queued, parts 1..8,
  source-wide abort, per-job usage on failure, extract peak == 3,
  audit peak == 1
- docs/architecture.md: serialized-audit paragraph rewritten for
  per-chunk jobs; two-front-doors wording aligned

amosblomqvist 3e9a85d60f per-session models: every session owns its model + thinking level from birth
The reported bug (2026-09-28): every chat ran glm-5.3-flash regardless of
any pick, while composer and settings UIs agreed with each other and lied
about the run. Root cause: a fossil default-settings record (settings.json
chat section, frozen pre-slots-wave) was stamped verbatim into every new
chat at birth by the new-session flow, and resolveConversationSpec prefers
the per-chat record over the strong slot forever.

Owner redesign — models are per session, always; the strong slot is the
new-session default:

- POST /api/chats stamps the newborn verbatim from the strong slot
  (model + thinking level); no client settings PUT on create anymore
- the composer control is dual-bound: in-session it reads/writes the
  session's own record (GET /api/chats/:id, PUT .../settings); on the
  draft surfaces it binds the strong slot (picking there = changing the
  default)
- thinking levels follow the identical mechanics (confirmed by owner)
- the zombie default-settings system dies whole: useDefaultSettings,
  /api/settings/defaults, src/store/default-settings.ts, the chat
  section of UserSettings (sanitizer strips fossil copies), the legacy
  default-settings.json fold, and DEFAULT_SETTINGS_FILE
- catalogDefaultsFor collapses to the strong slot alone
- thinking display for a legacy unstamped session resolves exactly like
  the engine (session ?? strong ?? model ladder)

Tests: new chat-birth-stamp suite pins the stamp, the unconfigured boot,
the unset level, and the copy-not-live-view regression; defaults pins
rewritten strong-only; legacy-migration suite deleted.

amosblomqvist f3003d357a 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).

amosblomqvist 7ab47d4fcb 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.

amosblomqvist e79f85ebe4 Prompt-override orphan trap: delete clears the switch, writes heal orphans
Contract-fix interlude (2026-09-26), two bugs from UI's prompts-overhaul
(6edc220):

(a) ORPHAN-400 TRAP: an ON switch whose override file dies orphaned the
record; every agent-section write then 400'd (ON-must-have-file) while
the disabled toggle couldn't reach the OFF escape hatch — a user stuck
unable to write settings. Verified live on 3004 before the fix.
Two-layer fix:
- DELETE /api/settings/prompts/[...segment] now clears the record's
  switch in the same operation (switch-first order: a crash between the
  two leaves the valid off+file state, never an orphan). Response gains
  switchCleared (additive). Overrules the 2026-09-19 switch-survives-
  delete note — the delete route and the record agree by construction.
- PUT /api/settings/[section] agent writes HEAL an orphaned ON to OFF
  (key dropped) inside the write — never a 400 (defense in depth: disk
  wipes outside the app can still orphan). A valid ON with its file
  stays valid; the invariant: a user can never get stuck unable to
  write settings, and the record never contradicts file reality for
  long. Heal logs at info.

(b) TEST WIPES REAL DATA: tests/prompt-overrides.test.ts wiped
data/prompts/ (REAL user override files) in after() and its empty-list
case — every npm test killed actual overrides and orphaned their ON
switches (feeding trap a). Isolated via the established LH_DATA_DIR
seam (mkdtemp + env set before the first config.ts-loading import; all
app-module imports dynamic). after() now snapshots the REAL repo
data/prompts before/after and fails the suite if it changed; the seam is
pinned (writes land under the temp dir).

Pins: delete-clears-switch (incl. idempotent no-op), the exact repro
(disk-level wipe → mirror-the-orphan + tool toggle → 200, healed key,
rest of the write landed), vanished-fragment ON heals, valid ON stays.
Live: the 400-forever write now lands 200, heal info-logged, record
clean.

Gates: 967/967 (+5), typecheck, lint, build green.

amosblomqvist 7cfd8b5bc7 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).

amosblomqvist e4049e4bf8 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.
2026-09-24 22:51:12 +03:00
amosblomqvist 3327309e8b The all-sessions coverage GET dies: the per-session block is the coverage surface
Extraction-UX close-out interlude (master dispatch 2026-09-24, off UI's
ff1ec7a confirmation): nothing client-side consumes GET /api/graph/coverage
— the sidebar block and the chat-bar ring both read GET /api/chats/[id]'s
coverage block. The dead route (app/api/graph/coverage/route.ts) is
deleted; the manual-extract front door (POST /api/graph/coverage/extract)
stays by design.

No server helper was orphaned — the route was composition-only over
shared seams (chatStore, extractionStatuses, stores, coverageOf). The
sessionCoverage doc + the chats/[id] route comment now point at the
per-session block as THE coverage surface.

Pin (tests/coverage.test.ts): the route file's absence (prompt-overrides'
structural-pin precedent) + the Extract POST's survival — a merge cannot
resurrect the dead surface silently.

amosblomqvist 2e9fd01c0c 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.

amosblomqvist 2d133f1133 Single-node deletion: full death by node id (node interlude, owner-locked)
The remedy for undeletable nodes (preserve-graph orphans from session
deletion; notes-import nodes with no chat behind them): DELETE
/api/graph/nodes/[id], full-death semantics — the user pointing at the
node IS the intent; references from other sessions do NOT preserve it.

- core/graph-deletion.ts deleteNodeTraces: the node's every line, every
  edge touching it, every quiz/observation event naming it, its mapping
  lines, and its resting position — one synchronous atomic rewriteLedgers
  call; only the ledgers that changed rewrite (mtimes stay honest). Blast
  radius is exactly the rows naming the node id; notes source records stay
  (deleting a proposition is not deleting the file). Derived data
  self-heals on read: the birth cluster shrinks below MIN_CLUSTER_SIZE and
  stops rendering.
- nodeDeletionImpact (GET /api/graph/nodes/[id]): the confirm dialog's
  pre-flight facts — edge count, quiz/observation history, referencing
  sessions. The snapshot's edges + nodeSessions cover part of this, but
  the raw event history was nowhere on the client — hence the read.
- Guards (server/graph.ts deleteGraphNode), decided + documented: NO
  turn/jobs gates (they never write graph ledgers; the orchestration is
  synchronous end to end, nothing interleaves). THE EXTRACTION GATE: 409
  while ANY pipeline run is registered — a mid-flight run holds
  pre-deletion findings and could re-reference the dying node. The run is
  never aborted (its spend belongs to another session — outside this
  deletion's blast radius; the UI retries once the dock drains. A run
  started after the deletion is legitimate re-learning: fresh ledgers,
  fresh node id, and mergeFindings' existingIds guard ignores linkTo ids
  that no longer exist — no dangling edges, no resurrection.

Live-verified on dev data: impact read, full-death stats, honest 404 on
repeat, and the file cluster fell 3→2 and unrendered itself.

859/859 tests, typecheck/lint/build green.

amosblomqvist c86430e8bf 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.

amosblomqvist 0a4a9a11de 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.

amosblomqvist a6338511d3 feat(graph): two-mode session deletion — the first destructive ledger operation
DELETE /api/chats/[id]?mode=preserve-graph|delete-nodes (mode required):
- preserve-graph: only extraction bookkeeping dies (coverage rows,
  legacy checkpoints) — graph ledgers byte-untouched
- delete-nodes: the chat's ledger traces die. Node survival = surviving
  provenance point / mapping line (notes imports carry empty
  provenance) / surviving event. The creator's aliases + provenance are
  stripped from a surviving node's create line (owner ruling
  2026-09-23: name/statement/createdAt are the shared identity);
  orphan nodes, their edges, events, mappings, positions, embedding
  vectors and cluster members die; cluster labels stay (immutable)

Gates: 404 unknown, 409 turn_in_flight / jobs_running (with jobIds),
503 extraction_winding_down after a 10s abort-and-poll; the purge is
one sync block (ledgers → jobs → chat record last). rewriteLedgers is
atomic (tmp + rename). graphRevision (max mtime over graph data files)
rides the activity feed + the response as the change stamp.

Anti-resurrection: the chat pipeline re-checks chat liveness at each
merge — a run that slips past the wind-down aborts with nothing merged
or checkpointed; its partial spend dies with the chat.

amosblomqvist 9387418864 feat(models): clamp-on-write for pinned thinking levels + DEFAULT_THINKING_ORDER in the core barrel
Fix 1 — clamp, never reject (owner ruling, interlude 2026-09-22): a
model swap with a pinned thinking level must JUST WORK. The owner hit
the write-side 400 live (Claude Fable 5.1/xhigh → GLM 5.3 flash:
"z-ai/glm-5.3-flash does not support thinking level xhigh"). The
supported-level verdicts in validateChatSettings and
validateModelsSettings are DEAD — the WRITE clamps the pin to the new
model's nearest supported level (pi's clampThinkingLevel, the same
translation piEngineForSpec applies at runtime) and stores the clamped
result; the server is the truth — the record shows the clamped level
after write.

New pure helpers in model-catalog.ts, applied by ALL THREE write
routes (section, defaults, per-chat — one verdict seam, so every
surface that used the old 400 gets the clamp uniformly):
- clampModelsLevels: every slot's level clamps against the SLOT'S OWN
  model (the parser already requires a model on each slot write).
- clampChatLevel: the body's own model, else the record's resolved
  strong slot (the chain's fallback); no model anywhere → rides
  unchecked (runtime clamps at engine build; the turn gate refuses
  the model-less chat anyway).

Fix 2 — DEFAULT_THINKING_ORDER moves from config.ts to core/settings
(core barrel, AUTH_KEYS precedent — one source of truth, no drift).
The UI imports it to auto-populate a thinking level on FRESH model
picks; the ordering has no other client role. Legacy unset records
keep the runtime defaultThinkingLevel fallback at engine build
untouched. Import sites updated: agent/models.ts, tests.

Verified live on 3004: the owner's exact case stores max (not 400);
a bare chat-level write clamps to low against the strong slot's glm;
unknown provider/model still 400s with the provider list.

Tests: the level-verdict suites became clamp suites (the owner's case
pinned verbatim: xhigh→max, minimal→low, off→low, supported
pass-through, level-less slots ride); the machine-aware
expectBareLevelVerdict chain is retired — clampChatLevel takes the
strong slot as an explicit param, so the tests are pure again.

Gates: typecheck, lint, 839/839, build.

amosblomqvist bfa906e2f8 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.

amosblomqvist f9e3a4c43d 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.

amosblomqvist f1373d5de5 feat(search): Tavily + Brave behind a search-provider port; Google CSE retires
Search port + model slots wave, chunk A (owner design, 2026-09-20):
- core/search.ts: SearchHit + SearchProvider port + SearchStatus —
  pure, browser-safe; adapters arrive as injected dependencies.
- server/search.ts: Tavily + Brave adapters (wire shapes VERIFIED
  against docs.tavily.com's OpenAPI + Brave's dashboard docs — Tavily
  auth is the Bearer header, not the legacy body api_key; Brave is
  X-Subscription-Token) + engine resolution per owner decisions: a key
  ALONE activates its engine (no engine choice needed), explicit
  agent.search.engine pins the preference (both keys: Tavily first),
  a pinned engine with a missing key is honestly unavailable — no
  silent fallback, no default engine.
- Curated keys catalog: GOOGLE_SEARCH_API_KEY/GOOGLE_CSE_ID retire
  (CSE closed to new customers, dies Jan 2027 — stored values become
  preserved unknown vars); TAVILY_API_KEY (tvly- shape) + BRAVE_API_KEY
  (length guard) join. UI keys-section TOOL_IDS now derives from the
  catalog — cannot drift.
- GET /api/search: {available, engine, reason} — the honest status for
  the settings gray-out; researcher-disable semantics ride the same
  signal (Teacher stream rewires the tool onto the port).
- agent.search settings field (schema + sanitizer + strict parser);
  web.ts's WebSearchResult is now the core SearchHit (re-exported).

amosblomqvist ec38f91a2b feat(keys): free-form model-provider keys — pi-ai provider table on /api/keys
Provider-keys interlude (owner spec, 2026-09-19): any pi-compatible
provider's key is manageable, not just the curated set.

GET /api/keys now also returns providers: {id, envVar, label}[] — every
pi-ai provider that takes a plain api-key env var (33 today), derived
from pi-ai's own provider→env-var table. No-drift mechanism: the table
is generated from pi-ai (builtinProviders + findEnvKeys over a
truthy-for-every-var proxy env) and pinned by
tests/auth-provider-keys.test.ts, which re-derives the truth at test
time and asserts EXACT equality — a pi-ai upgrade fails the gate loudly.

Owner-spec exclusions: github-copilot (OAuth), amazon-bedrock (AWS),
google-vertex (ADC), azure-openai-responses (base URL), the cloudflare
pair; anthropic keeps ANTHROPIC_API_KEY only. OPENROUTER_API_KEY
graduates from the curated catalog to the provider table (dedupe — the
UI pins it always-visible); curated stays Deepgram + the Google search
pair. Statuses: curated + present vars + unknown file vars — absent
provider keys never spam rows; the dropdown is discovery.

Write side: PUT/DELETE accept provider env vars (generic truncation
guard — trim, no whitespace, ≥12; family checks stay on the curated
three). Present-in-env provider vars surface as status rows so
env-wins/shadow semantics stay honest.

amosblomqvist 3e263a18cc Graph pipeline cost metrics: capture naming spend, fold all channels, cost pill + panel
- Cluster namer bills the money channel now: per-step usage + model
  captured via onStep, persisted as NamingRunUsage records to
  data/graph/naming-runs.jsonl (idempotent per startedAt; failed/aborted
  runs persist too — money spent either way). callUsage promoted to
  extraction.ts module scope for reuse.
- core/cost-summary.ts: the pure fold behind the pill — chat runs,
  notes-source runs, and naming runs into stage totals (extraction /
  audit / naming) + newest-first recent runs. Dollars INFERRED read-time
  via prices.ts, never stored; unpriced models excluded-but-counted
  (render '—', never a silent zero); tokens always sum.
- GET /api/graph/costs (src/server graphCosts composition, thin route).
- Graph view: bottom-left cost pill (cumulative dollars headline) +
  expandable breakdown panel (stage rows with tokens secondary, recent
  runs with time/title/merged/cost); fetched on mount, refetched when a
  pipeline run finishes; merged into one bottom-left stack with the
  running-pipeline pills.

  naming path), store idempotency + strict reads.

amosblomqvist cbaf6df454 feat(keys): first-class BYOK key management — store, catalog, /api/keys
The auth/keys wave (2026-09-19): the server now owns the flat auth.json
map directly (LH_AUTH_FILE from main.cjs; repo-root auth.json in dev,
gitignored). The store reflects itself into the child's env at boot with
fill-gap precedence — real env (incl. .env.local in dev) always wins —
so every consumer keeps its plain process.env reads and saved keys take
effect immediately, no restart; main.cjs's spawn-time injection retired
(an env copy would shadow every settings-page change).

Curated 4-key catalog (OpenRouter, Deepgram, Google search pair) with
shape-only validation (no live pings — owner decision), 400s on bad
pastes, last-4+length masking (plaintext never leaves the store),
unknown file vars preserved + surfaced. Routes: GET /api/keys,
PUT/DELETE /api/keys/:id. Tests: catalog/store/composition, with the
env-sanitizing prologue (a dev shell may export real keys; tests use
throwaway values only).

amosblomqvist bd3086194f feat: no baked-in default model — the new-session controls ARE the default settings page
Owner reframe (2026-09-18): the model + thinking + context controls on
the home graph view and /chat/new are not a draft overlay on a baked-in
default — they ARE the settings page for the default model, and the
user's last choice IS the default. BYOK first boot has no keys and
possibly no OpenRouter, so there is NO default to show: the controls
render 'no model' ('—') until the first pick.

The flash was the deeper symptom: the surfaces rendered from client
state that started empty and fetched truth afterward, so every visit
flashed the config pin (GLM/low — a dev artifact) for a few frames.
Fix at the root: both pages are now force-dynamic server components
that read the record (readDefaultSettings → initialSettings) and hand
it to the client — the first frame shows truth. Dynamic routes aren't
cached client-side (staleTimes.dynamic = 0), so every navigation
re-reads the record; the useDefaultSettings hook keeps only save-side
state (optimistic set + PUT). The GET-on-mount and its touch-guard are
gone.

ModelControl gains noDefaultModel (the default surfaces only): unset
settings render no model/level, never the catalog pin; the thinking
menu no-ops until a model exists. Chat surfaces keep the catalog
fallback — the engine runs the config pin when a session record has no
override, so the control keeps showing what will actually run.

Renamed draft→default throughout: data/default-settings.json,
GET/PUT /api/settings/defaults, useDefaultSettings. New sessions
still inherit the default on creation exactly as before.

Live-verified: first-boot 'no model' with zero flash, picker +
Shift+Tab cycle, values held across session→/chat/new→home roundtrips
and a reload (10×100ms samples, never the old default), zero console
errors.

amosblomqvist a94a108e74 feat: draft settings persistence — shared model/thinking/context record for the new-session surfaces
Both new-session pages (the home graph view's topic dock and /chat/new)
held their model + thinking + knowledge-context choices in plain
useState(undefined) — every navigation reset them to config defaults.

Now both surfaces read/write ONE server-side record
(data/draft-settings.json via GET/PUT /api/settings/draft, the
render-settings pattern): whatever the learner last left the controls on
is what every later visit shows. useDraftSettings loads on mount with a
touch-guard (a slow GET never clobbers a fast choice), saves
optimistically. Session creation still carries the choice into the new
chat exactly as before; per-session settings are untouched.

The PUT validation is the exact per-chat contract — parseSettingsBody
extracted verbatim from app/api/chats/[id]/settings and shared by both
routes (unknown model/level → 400 with the supported list, never a
silent clamp). 400s on garbage, {} = the clear-overrides write.

Live-verified: Cmd+K+Enter model pick, Shift+Tab thinking cycle, context
slider — all held across home → session → home → /chat/new, and carried
into a created session's record.

amosblomqvist 573e369db5 fix: dictation cloud path — bearer subprotocol, access_token grant field
Two live-verified Deepgram facts from the first real mic-test round:
- /v1/auth/grant returns { access_token }, not { token } — the route now
  parses the right field.
- Minted JWTs authenticate over the WebSocket via the "bearer"
  subprotocol; ["token", jwt] is rejected at the handshake (token is
  for raw API keys only, as in the pi dictate extension).

Also documents the env-precedence gotcha in docs/research/stt.md: a
DEEPGRAM_API_KEY exported in the shell (e.g. .zshrc) silently beats
.env.local in next dev and the desktop authEnv() seam.
2026-09-17 19:44:35 +03:00
amosblomqvist e3bdbc2f2c feat: voice dictation (STT wave 1 — Deepgram cloud)
Two-band architecture from docs/research/stt.md: renderer captures mic
audio in an AudioWorklet (linear16 16kHz mono, ~128ms frames, per-quantum
RMS for the meter) and streams it directly to Deepgram over WebSocket —
audio never loops through our server. The real key stays server-side;
/api/stt/token mints a short-lived grant token (TTL 300s) per run.

Patterns ported from the owner's pi dictate extension (tuned in real
use): generation counter guarding every async handler, the
latest-RMS-never-resets meter (-50..-10dB window, 60ms tick), mic-first
stop + CloseStream + 3s safety net, endpointing=300 with the
utterance_end_ms=1000 backstop.

UI (owner placement): mic button in the stats bar's middle slot on all
three surfaces (home graph-view, chat, draft); while recording the meter
unfurls to fill the row's free width with the interim ghost at its
flank. Esc ends dictation from the composer. Token mint comes before
getUserMedia so a keyless app fails fast without a TCC prompt; one
automatic reconnect on abnormal socket close, errors surface inline.

Live-smoked the full error path in the dev shell (bar renders on all
three pages, 403 grant failure shows inline, mic untouched). The full
audio path needs a Deepgram key with Member permission to mint tokens.

amosblomqvist 769a3da186 feat: session rename + graph chrome polish (popovers dismiss, no-shift no-match, coverage reseat)
Rename (owner ask): clicking the header title opens edit mode with the
whole title selected — typing replaces, arrows move inside. Enter or a
click away commits (PUT /api/chats/:id); Escape and an empty commit
discard. renameChat joins the ChatStore port; like saveSettings it is
NOT conversation activity — updatedAt stays put so sidebar order never
churns on a rename. The sidebar patch is instant: the header dispatches
lh:chat-renamed and SessionsSidebar folds it into its snapshot (the 2.5s
poll is only a backstop). Sidebar right-click rename is DELIBERATELY
deferred: it needs a real context-menu system, which gets its own pass
later (owner decision, 2026-09-17).

Graph chrome:
- The extraction-coverage button moves between search and import; the
  gear keeps the far-right corner. Coverage still renders on an EMPTY
  graph (that is exactly when it matters).
- The no-match search note no longer shifts its siblings: the chrome
  row is items-start (every button is 44px tall, so top alignment pins
  the row while the search container grows downward).
- Popovers dismiss properly: pointerdown anywhere outside the control's
  root (button + panel) closes it, and so does Escape. Two panels can
  never be open at once — the sibling chrome buttons are outside the open
  root, so pointerdown closes the first before the click opens the
  second. New shared hook components/popover-dismiss.ts, wired into
  both the settings gear and the coverage control.

Gates: typecheck, eslint, 498/498 (+2 rename store tests), build.
Live-verified: select-all/focus/Enter/Escape/empty/blur round-trip,
updatedAt untouched, sidebar instant patch; chrome order + frozen
positions under a no-match query; popover close via canvas, search
input, Esc, mutual exclusion, toggle intact.

amosblomqvist 5c380de669 Merge lh-ui refinement wave (feat/ui-polish @ 8163437) into main
11 commits on fbeca36: minimal-color rounds 1-2 (phase color retired,
the braille spinner is the one working indicator; the chip is label-only),
typography rounds 1-5 (three-font rule enforced — CMU titles, Source Sans
session titles, JetBrains mono; snapped type ladder in globals.css with
the xxs rung merged into xs; lh-input caret at the font-metric floor;
session titles at prose size, message counts and active-row weight dropped,
ISO dates), header rounds 6/6b/6c/6d (60px top bar aligned to the sidebar
LH band; the open-sidebar toggle matches the close glyph at size-4 both
ways; SidebarToggle always-mounted with a lockstep animated slot — no more
one-frame title jump; title at text-3xl).

Semantic change folded in: `busy` in the chats list now means exactly "a
teach turn is in flight" — background jobs no longer spin the session row
(the sidebar's Background agents section is their channel).

Merge fallout fixed in the merge: components/graph-coverage.tsx (main's
coverage panel) held the last three text-xxs uses; with the rung deleted
they silently lost their size — mechanically swapped to text-xs, matching
lh-ui's own swap in graph-context-marker.tsx.

No file overlap with main's waves since fbeca36 (extraction coverage,
lh-graph merge, world-scale bake) — clean auto-merge. Gates: typecheck,
eslint, 496/496 tests, build. Live-verified on the dev server: 60px
header with 32px CMU title, label-only chip, snapped ladder active
(--lh-prose-size 16px, no --text-xxs rule anywhere), sidebar rows with
ISO dates, animated sidebar toggle with no header jump.

pipeline has extracted, by content fingerprint over exactly what the
extraction view sees (one shared line builder — core/coverage.ts); the
uncovered remainder is DERIVED at read time, never dual-tracked. A quiz
answer merging into the asking message re-opens only that message;
plan-block data-part attach never re-opens anything.

- The trigger (turn-service) replaces every-3-quiz-answers with
  uncovered-tokens >= EXTRACTION.chunkTokens (4096) — quiz-less sessions
  extract too, content size is the honest signal.
- runExtraction is now chunked: token-budgeted batches of the oldest
  uncovered consecutive messages (a tool call + result never split), each
  merged batch checkpointing its messages' coverage atomically — an abort
  or error loses at most the in-flight batch; merged batches stay covered.
- Observation refs are batch-tagged (obs:<batchTag>:<sourceId>): re-runs
  of the same batch dedupe; a re-opened message's fresh understanding
  lands as a new event. Fixes the old obs:p1 position-collision.
- New API: GET /api/graph/coverage (exact per-session derived coverage +
  running flags, most-uncovered first) and POST /api/graph/coverage/extract
  (manual run for one session, 409 while in flight).
- Graph view chrome: the coverage button opens a panel with every
  session's covered/uncovered tokens and a per-session Extract button —
  the manual answer to aborted runs, errors, and dormant tails. Renders
  even when the graph is empty: an empty graph with uncovered sessions is
  exactly when it matters. Polls only while open.
- Notes imports keep the whole-file checkpoint path (coverage undefined).
- Tests: pure-core coverage suite (11), chunked-pipeline suite (3:
  multi-batch + no-op, abort-keeps-earlier-batches + remainder re-run,
  re-open alone + data-part invisibility), panel render suite (5);
  pendingQuizAnswers and its tests deleted as dead code. 486/486.

Live-smoked on real GLM: manual extract of "teach me modal realism" ran
one batch, wrote 4 coverage entries, panel flipped to "1.3k covered ·
complete" with the button disabled, graph refetched (nodes 11), usage
persisted with real stats.

amosblomqvist 326222f53c Minimal-color round 1 (owner): phase color retired — the braille spinner is the one working indicator
Nothing exists purely for decoration: phase color-coding is retired
app-wide (phases only advance — every session ends Teaching — so
phase-as-signal was decoration with a one-time function), and what
state genuinely deserved — 'a turn is in flight' — is now carried by
MOTION alone, in the terminal's own glyph language.

- BrailleSpinner (components/braille-spinner.tsx): the canonical
  cli-spinner sequence (⠋⠙⠹⠸⠼⠴⠦⠧⠇⠏) as exact dot bitmaps in a 2×4
  braille cell, 80ms/frame (800ms cycle). Pure CSS: one shared keyframes,
  frames staggered via animation-delay; no JS timer, no re-render per
  frame — cheaper than the old breathing dot. Static contexts (SSR,
  prefers-reduced-motion) show frame 0 — a legible glyph, not a blank.
- Sidebar rows: spinner ONLY while a teach turn is in flight; idle and
  question-pending render NOTHING (a resting state has no scan value —
  the meta line's 'Waiting for your answer' text carries it). The
  three-state phase dot (pulse/solid/hollow) and PHASE_FILL/RING maps
  are gone.
- Top bar PhaseChip: label-only pill; the old dot slot becomes the
  spinner's home while a turn is in flight (busy prop wired from
  ChatView's busy = localStream || turnInFlight). Transcript
  PhaseDividers drop phase colors for monochrome rules + labels.
- API narrowing (app/api/chats/route.ts + ChatListItem contract):
  busy = isTurnRunning ONLY — background jobs no longer count (the
  sidebar's Background agents section is their channel; a per-row
  spinner would double-signal them).
- globals.css: --phase-* tokens + lh-dot-breathe removed (dead after
  the sweep — no remaining users).

Live-verified: idle/pending rows render no indicator, /chat/new chip is
label-only, 10 CSSAnimations at 800ms with correct 80ms stagger, static
frame 0 under reduced motion. Gates: typecheck, lint, 470/470, build.

Lane crossings to flag at merge: app/api/chats/route.ts + the
ChatListItem contract comment (src/core) — the busy-semantics narrowing;
components/chat.tsx one-line busy prop.

amosblomqvist 1d45d77303 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.

amosblomqvist 05712037b2 Live physics drag + splat cluster regions
The renderer grows a live d3 sim (createGraphSimulation, shared with
the server settle): pointerdown on a node pins fx/fy and pointer capture
(preventDefault kills the compat mousedown, so d3-zoom never pans); the
first CLICK_SLOP-exceeding move reheats to alphaTarget 0.3; release
un-pins and the sim anneals (release-and-relax) — alpha < 0.005 settles
it, a 250ms debounced onCommit PUTs the rest state. Verified live: 123fps
during a 320ms drag (regions rebuilding every 3rd frame), 85-tick settle,
then zero idle frames. A slop-free press stays a click (select, no reheat,
no commit). PUT /api/graph/positions sanitizes (finite coords, known ids)
and if the graph grew mid-drag runs ONE incremental settle with the
client's arrangement as anchors (50-id PUT test: anchored drift 0.15).

Cluster regions swap convex hulls for a low-res world-space SPLAT bitmap:
per-member radial-gradient discs (alpha 0.2) + intra-cluster edges as
round-cap strokes (Minkowski dilation — concave shapes finally render),
upscaled with bilinear smoothing (the upscale IS the blur, no ctx.filter:
Safari). One tiny blit per frame replaces 32 clusters x 4 offset
Path2D polygons re-rasterized at DPR 2 (the old GPU coil-whine path);
during the live sim the bitmap rebuilds every 3rd frame. cluster-geometry.ts
retires convexHull/offsetPolygon/traceRoundedPath (tests follow; clusterHue
stays). Region labels stay (centroid + clusterHue, inverse-gated on zoom).

amosblomqvist ecadededd9 World-space rendering: geometry cached once, zoom pays only rasterization
Fixes the zoom frame-rate collapse and rebuilds draw() around a single
camera transform, per the user's Obsidian-style sizing proposal.

Bug fix first: the eased zoom leaked a queued rAF callback per frame --
advanceZoom applies each step through d3-zoom, whose zoom event called
markDirty() from inside the tick loop, scheduling an extra draw while the
loop scheduled its own. Draws multiplied per displayed frame; sustained
wheel ran at ~20fps against a 120Hz display. markDirty now skips
scheduling while inTick (verified: 62 frames/500ms during a 28x zoom
burst, matching pan).

World-space model: every draw call now runs in graph coordinates under
one setTransform(k). Sizes are defined as screen-px-at-fit and converted
once per geometry build (/ kFit), so nodes, node labels, arrowheads and
the hover halo scale with the graph as you zoom (0.25x painted area at
half zoom, exactly k^2) while edge widths and hull borders stay
viewer-relative hairlines (/ k). Cluster hull geometry (convex hull +
three offset fills + solid boundary -- dashes dropped for now) is built
as cached Path2Ds per data/visibility/settings change; camera moves do
zero geometry math, making zoom per-frame cost identical to pan. Label
wrapping runs once per build, not per frame. Region labels stay
viewer-relative (18px at any zoom) as UI chrome. Picking radius scales
with the world-sized discs.

Glide feel: ZOOM_EASE_MS 120 -> 45, convergence 0.1% -> 0.2%; a notch now
settles in ~260ms instead of ~750ms. Resize still paints synchronously.

Also fixes barrel-law lint violations from the settings wave (import
from @/src/core and @/src/server, not deep module paths).
2026-09-13 07:18:37 +03:00
amosblomqvist 8e2d2118a6 Graph view refinements: server-persisted settings, label size, eased zoom, resize-blank fix
Five refinements to the hand-rolled renderer, all user-directed:

1. Settings are SERVER-persisted (data/render-settings.json via new
   GET/PUT /api/graph/render-settings) - one source of truth for every
   browser, replacing localStorage. The client loads once after mount,
   saves debounced on user changes, and never lets a slow GET clobber a
   faster user (or mounting PUT defaults over the server copy). The
   shape/defaults/sanitizer moved to src/core/render-settings.ts - pure,
   shared by client, server store, and tests; every disk/network value
   passes through sanitizeRenderSettings.

2. New "Label size" control (default 12px - the previous hardcoded size).
   Font, wrap width, and line height all scale; verified live: +76k px
   with the label gate open.

3. "Labels until zoom" slider reworked: log-scaled over 0.0625-4 so the
   useful band (0.25-0.5 camera-ratio units) sits at 33%/50% of the
   track instead of crammed at the far left of the old linear 0.25-4
   slider. Display units are normalized: the default 0.5 reads as "1x",
   0.25 as "0.5x". The underlying labelZoom semantics are unchanged,
   so existing values survive.

4. Smooth wheel zoom: d3-zoom instant per-notch jumps (x1.2, bang) are
   replaced by an eased glide - wheel events accumulate a cursor-anchored
   target scale and each tick eases the camera toward it (exponential,
   120ms constant, frame-rate independent). Pan/pinch stay d3-owned; a
   pan cancels a glide in progress. Verified live: 8-frame glide.

5. Resize blanking fixed (graph vanished for the duration of a window
   drag, reappearing ~300ms after). Cause: every resize event
   reallocated the canvas backing store - which CLEARS it - and the
   redraw was deferred to rAF, which live resizes starve via relayout,
   so the canvas sat wiped for the whole drag. Fix: the ResizeObserver
   callback now redraws SYNCHRONOUSLY after reallocating (verified via
   a probe RO firing in the same delivery batch: canvas fully painted).
   kFit (the label gate 1x reference) is also recomputed on resize from
   the now-cached world bbox - the camera itself still persists.

tests/render-settings.test.ts: 10 tests pinning the sanitizer (garbage/
partial/clamps, legacy no-labelSize records) and the slider mapping
(default dead-center at 500, monotonic, exact round-trips, display
units). 402/402 green; typecheck, lint, build pass.

amosblomqvist 543cf33789 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.

amosblomqvist de0c286311 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.

amosblomqvist 37c4638feb Merge feat/graph-rendering: wave 4 — extraction usage capture (live + persisted), true abort
# Conflicts:

2026-09-11 03:28:23 +03:00
amosblomqvist 9174cde55e Extraction observability: usage capture, live status payload, true abort (Wave 4)
Extraction is real spend and background work; the dock needs to see
and stop it. User decisions: persist all cost data (chat record),
per-stage usage granularity, and TRUE cancellation for abort.

USAGE CAPTURE (live + persisted):
- extraction.ts: per-call onStepFinish captures each billed step's
  usage (SDK LanguageModelUsage -> CallUsage: input/output/cache
  read+write/reasoning) into the registry's live per-stage usage
  (extractor/auditor; the merger is deterministic — no model call).
- /api/graph/status runs now carry usage (model + steps per stage);
  cost/context folds are the consumer's (core/prices.ts — nothing
  stores dollars).
- ChatRecord.extractions: append-only per-run usage log (mirrors the
  turns log): startedAt key, at, durationMs, merge stats when the
  merger ran, stages. Persisted on success AND failure — a failed run
  still spent money. Idempotent per startedAt; the list payload
  (ChatSummary) never leaks it.
- EmissionStats moved to contracts/graph.ts (its contract home);
  core/graph.ts re-exports for existing importers.
- Verified end-to-end against the real pipeline (backfill one chat):
  per-step token counts, reasoning tokens, and the auditor's growing
  prompt-cache reads captured and persisted.

TRUE ABORT (the dock's abort button, user decision):
- RunningExtraction owns one AbortController per run, shared across
  phases; abortExtraction(chatId) fires it and returns whether a run
  was aborted (idempotent no-op otherwise). The pending model call
  receives the signal — the provider cancels the request, spend
  stops. throwIfAborted() at phase boundaries ends runs aborted in
  sync gaps.
- Abort is a deliberate stop, not a failure: same ledger discipline
  (nothing merged, nothing checkpointed, partial usage persisted) but
  the run reports zero emissions instead of throwing. Exported via
  src/server/observability.ts for master's /api/activity/abort route.
- Tests: mid-run abort (hanging mock that rejects on the signal),
  live-accumulation + persisted-record assertions, store-seam
  idempotency, and the summary-payload leak guard.

amosblomqvist f8ba5b1628 Activity feed: one dock-shaped GET /api/activity (cross-chat processes)
The dock is visible in every view, so it needs every running process —
sub-agent jobs across ALL chats (not just the open one) plus the global
extraction runs — in one poll. /api/jobs stays chat-scoped and untouched:
it is the transcript machinery's poll and carries turnInFlight for the
re-attach seam (chat-transport), the seam we spent three live rounds
stabilizing; making it polymorphic would fork its response shape by mode
and put regression risk on exactly the wrong path. The dock is a different
consumer with a different shape (cross-chat, running-only, cost-bearing),
served by a thin route over server/observability.ts:

- activityFeed(): running jobs from every chat (title-joined, oldest-first
  on last activity) + extraction runs + busyChats (chats with a teacher
  turn in flight — the biggest spender; data made available, rendering is
  a dock decision).
- GET /api/activity — the dock's single poll everywhere.
- Cost math stays client-side (core/prices.ts folds); raw usage rides the
  records and the transport stays thin.

Decided with the user over the polymorphic-/api/jobs and
separate-all-jobs-endpoint alternatives.

amosblomqvist 83a00800e9 Observability contracts: usage accounting, plan blocks, price table (Phase 0)
The 2026-09 observability wave's type-level foundation, landed before the
streams so nothing renders against guessed shapes:

- contracts/chat.ts: CallUsage + TurnUsage (per-model-call token accounting,
  one entry per teacher/wake turn keyed by messageId) and ChatRecord.turns —
  a DELIBERATELY parallel append-only usage log, not per-message metadata:
  the client re-POSTs its message list every turn and its copies never
  carry server-stamped fields, so anything inside messages gets clobbered
  by the next persist (the wave-3 merge-rule lesson).
- contracts/chat.ts: PlanBlockData — the persisted data-plan-block part
  (full DAG on plan_init, one-level neighborhood on plan updates, snapshot
  semantics so history renders what was true then).
- contracts/jobs.ts: JobUsage + JobRecord.usage — a sub-agent run's
  accumulated accounting, written by the runner.
- core/ports.ts + store/chats.ts: ChatStore.appendTurnUsage — idempotent
  per messageId (abort replays / wake retries append once); listChats no
  longer leaks turns into the list payload.
- core/prices.ts: PRICES + CONTEXT_LIMITS (generated from OpenRouter's
  published pricing via scripts/sync-pricing.ts) + pure folds: callCost,
  turnCost, sessionCost, contextWindow, jobCost. Unknown model or absent
  fields render as absent, never zero.
- server/observability.ts: barrel-approved surface for the transport layer
  (fixes the import-law violation in the graph status route that slipped
  through the wave-3 merge verification).

Capture wiring (agent onStepFinish -> persist seam, plan-block emission)
lands next as master seam work; the streams start against these shapes.

amosblomqvist 0c12d53fca Background pipeline status: registry + /api/graph/status + graph-view chips
The background extraction pipeline is invisible on the home surface —
essential observability per the user's directive: the graph view must
show what is currently running (extracting / auditing / merging) and
for which chat.

- extraction.ts: module-level registry of in-flight runs (chatId,
  phase, startedAt), updated at each phase transition in runExtraction
  and cleared in finally (done or failed). extractionStatuses() is the
  read; one process, one registry.
- GET /api/graph/status: thin transport over the registry, chat titles
  joined from the chat store.
- graph-view: polls every 2s and shows one chip per running pipeline
  (spinner + phase + title + elapsed seconds, bottom-left); when a run
  finishes (some -> none) the graph refetches, so merges land live.
  Status is cosmetic — poll errors never surface.
- Unit test drives a mocked pipeline run and observes the registry
  mid-flight: 'extracting' during the extractor's generate, 'auditing'
  during the auditor's, empty after.

amosblomqvist 25df0edd5b Merge feat/ui-polish: three-phase session model, plan graph, layout restructure
chat.tsx woven by hand: UI's session-surface layout (transcript column +
right sidebar as full-height siblings, h-10 header with PhaseChip) wrapped
in sub-agents' JobsContext.Provider; the message map carries both the
steer ternary (steers bypass the Message wrapper — the model-facing glue
text never renders) and UI's PhaseDivider emission (steers are verified
phase-boundary no-ops). Right sidebar = sub-agents' fleet panel column
(SubAgentsPanel above TreePanel, xl-only) carried onto UI's skeleton.
contracts.ts auto-merged (ChatSummary.phase/pendingQuestion + ChatListItem,
additive above the async-protocol section).

Smoke-verified on the merged tree: steer renders bare as its artifact
badge with no learner bubble, no rendered glue text, and no spurious
phase divider at the steer boundary.
2026-09-02 16:40:47 +03:00
amosblomqvist 2d7b004fda fix: live sub-agent observability — dispatch cards, steer artifacts, sidebar panel
The pi-style ack protocol (previous commit) left the client describing the
old world: artifact cards read the ack string as a result ("could not be
displayed"), the only job poller rendered on input-available parts that no
longer exist (so wake turns landed invisibly until re-navigation), steers
rendered as learner bubbles with no SVG anywhere, and server-persisted
assistant messages carried empty SDK ids (duplicate React keys).

- persistTurn (turn-service): fill empty message ids at the canonical write
  — server-only messages (last turn's, wake turns') now key uniquely;
  client-authored ids untouched.
- chat.tsx: ONE central /api/jobs poll (fast while jobs run, slow discovery
  cadence, off for job-less sessions) drives every job surface, re-syncs
  once when a job settles (the record already holds the steer + wake
  response at flip time), and adopts server-side wake turns via the same
  turnInFlight machinery as returning mid-turn. Steers branch to the
  artifact card — never a bubble. Composer no longer gates on jobs.
- /api/jobs now reports turnInFlight alongside the job list.
- dispatch-card: the tool-call box — live activity by toolCallId while
  running, quiet "delivered"/"failed" one-liner after; the ack is visible
  observability, the artifact lives in the steer.
- steer-card: renders the delivered artifact by kind (research brief /
  sanitized SVG / sandboxed demo iframe) from the data-subagent-artifact
  part; result renderers extracted and exported from the artifact cards.
- sub-agents-panel: right-sidebar section above the plan tree listing
  running sub-agents (kind, elapsed, live activity) — vanishes when idle.
- tests: dispatch/steer/panel render tests re-target the new protocol;
  persistTurn id-hygiene suite. 229/229 green, build green.

Out-of-lane touches for master review: chat.tsx + components/** (cleared
this wave), app/api/jobs/route.ts, src/server/turn-service.ts, contracts
