practice slice 1 — contracts, the chain bijection, coverage
src/core/contracts/practice.ts (new domain): ReasoningChain (group by conclusion, id = conclusion node id), PracticeParams (three 0..1 dials), ProblemSet/Problem lifecycle, feedback-only ProblemGrade. src/core/ practice.ts: chainsForSelection (follows-only, both-ends-in-selection, group-by-conclusion, singletons for edge-less nodes), chainsToGraph (the exact inverse — bijection pinned), chainCoverage (the completeness law: union of problems' chains = the set's chains; duplicated allowed). 13-test suite: diamond, premise-only, singleton, supports-invisible, outside-endpoint, dedupe, determinism, round-trips, coverage cases. |

delete the mappings ledger — per-job in-memory resolution + notes fingerprint guard
The persisted (chatId, sourceId)→node table was a shared namespace across independent chunk/batch jobs: each chunk's extractor mints local ids fresh (p1..pN), so later chunks collided with earlier ones — propositions silently skipped as 'already resolved' (coverage checkpointed anyway: permanent silent loss) and edges resolved onto the wrong nodes (the 'everything links to everything' mush). Owner ruling 2026-09-29: mergeFindings resolves THIS job's ids in memory, nothing persists between jobs; cross-job identity is the auditor's linkTo verdicts alone. - contracts: NodeMapping dies; NotesSource.contentFp — sha256 of the text at the last run, the re-import guard (unchanged re-import = TRUE no-op, no model calls, no usage; changed text re-runs; legacy unstamped sources re-run once) - merger: job-local resolution map, in-submit duplicate ids skip once, edges resolve extractor-local ids only - ports/store: appendMapping/readMappings, LEDGER_FILES.mappings, rewriteLedgers.mappings gone (stale data/graph/mappings.jsonl just stops being read) - session-clusters: birthSessionOf is provenance-only — the legacy mapping-line fallback for provenance-empty notes nodes dies - deletion: no mapping rows to strip; stats lose mappingsRemoved - replay-layout batches nodes by first provenance point - graph.test pins the new independence semantics (re-merge re-creates; duplicate ids within one submit resolve once); extraction tests pin per-chunk merges + the fingerprint guard |

Auditor submits links ONLY — the edges argument is gone (owner, 2026-09-28 evening)
Hypothesis under test by the owner: coherent extractions turn to mush after merging because the auditor minted too many bridging edges of its own — inference, not identity, and out of the auditor's scope. The graph now connects across sources solely through identified equivalences; relations between propositions come from the extractor alone. - auditSchema drops 'edges' (submit_review = links only); the submit-seam required-field doctrine reworded per tool - AUDITOR_INSTRUCTIONS: the BRIDGING EDGES section dies; deliverable is the identity verdicts only - AuditVerdicts drops edges; ExtractedEdge endpoints are extractor-local ids only; mergeFindings stops consuming verdict edges and its resolve() drops the raw-node-id branch (dead — the extractor never sees graph ids) - extractor untouched: submit_findings keeps propositions + follows/ supports edges, required as before - tests: 17 submit fixtures + 9 typed verdict literals slimmed to links - docs: architecture.md division-of-trust + pipeline diagram updated |

verdicts-only auditor: submit_review is {links, bridging edges} — the findings echo dies
Owner ruling 2026-09-28: the auditor has no control over the extractor's output and never alters it, so re-emitting the full findings per submit was pure payload cost — the retry collapse the schema slim attacked, halved again. submit_review is now links (local proposition id -> existing graph node; EQUIVALENCE BIAS carried in the linkTo description) + bridging edges ONLY; the merger joins extractor findings + verdicts. mergeFindings(chatId, findings, verdicts, ...) — propositions come from findings verbatim, links join by id, edges emit extractor's then auditor's through one dedup-preserving emitter. The old echo form hid an accidental drop channel: an auditor that omitted a proposition from its echo silently dropped it from the merge. Verdicts-only removes it structurally — extractor output always fully merges (tests updated to full-merge expectations). AuditResult/AuditedProposition -> IdentityLink/AuditVerdicts; audit() logs links/bridges; batch view renders anchorless like transcriptView; auditor prompt rewritten to the verdicts-only deliverable; architecture.md division-of-trust updated. |

slim the submit schemas: evidence and messages die; stringified-payload heal at the pre-validation seam
OpenRouter log diagnosis (owner, 2026-09-28): extraction time was
dominated by tool-validation retries. The failing call had the whole
propositions array emitted as ONE JSON-STRING ('propositions.0: must
be object'), a truncated placeholder artifact inside it, and
word-salad statements late in the array — payload-size collapse.
Field audit: 'evidence' was never persisted anywhere and its
faithfulness-checking consumer died with the fully-trusted ruling;
'messages' fed messageId granularity that NOTHING downstream reads,
and the model sent [] anyway (chat-level provenance in practice).
'aliases' stays (optional now): the auditor's find tool globs them.
Schema: propositions = {id, name, statement, aliases?}; edges =
{from, to, type}. Prompts lose the evidence/messages doctrine and
[id]-anchor guidance, gain a compact faithfulness line;
transcriptView renders anchorless. The auditor echo instruction
drops the evidence/messages mention, so its payload halves too.
Heal: healStringifiedArrays on the submit tool's prepareArguments
(pi-agent-core's sanctioned pre-TypeBox shim) parses a stringified
propositions/edges back into arrays — the LaTeX-restore doctrine:
heal weak-model wire behavior at the seam. Test drives the real
agent-loop seam with a stringified submit.

extraction cleanup: events ledger dies, markdown source view, auditor-as-linker (2026-09-27 rulings)
The graph becomes raw reasoning chains only. Quiz outcomes and understanding observations are no longer formalized; assessment moves to the future practice module. Events ledger removed end-to-end: LedgerEvent/LedgerEventKind/ UnderstandingLevel/ExtractionAttribution/AuditResult.dropped and snapshot nodeObservations deleted from contracts; quizEvent builder and the events step of mergeFindings gone; appendEvent/readEvents dropped from the port and store; LEDGER_FILES loses events.jsonl with a one-time purge of a stale file next to the nodes ledger; graph-deletion and the delete dialog lose event purge + quiz-answer impact counts; GraphSessionProposition becomes a pure birth list. Whole-session markdown source view: new core/session-markdown.ts is the shared formatting engine (id-anchored speaker blocks, quiz/ recall/question blocks, tool one-liners) — the extractor's prompt view and the future user-facing export render from one engine. Coverage fingerprints deliberately stay on the old line format (content-hash semantics; re-formatting never re-opens covered history). The whole session goes to the extractor — no phase cut. Auditor refocused as the identity linker: never sees the source; explores the graph via new auditor-specific tools in agent/tools/graph.ts (find — glob over name/statement/aliases; list_sessions; list_propositions with full statement text; no timestamps) instead of an injected full-graph dump; equivalence bias — paraphrases merge, only genuinely distinct propositions stay apart; no drop channel, the extractor is fully trusted; may draw bridging edges (typed follows/supports) between existing nodes and the batch, resolved by the merger with chat-scoped message-less provenance. Agentic loop, maxTurns 16. UI: the node detail card gains an edges section above the sessions list (follows-from / supported-by / what-follows / what-it-supports, rendered only when present, click-to-select neighbors); the understanding-note chips are gone. Prober list_propositions reworded to what a session covered — names only, no levels. docs/architecture.md + README updated to the as-built pipeline. Gates: typecheck, 1059/1059, lint, build. |

free-recall explain tool: the quizzing-mechanic switch (owner 2026-09-27)
Sycophancy mitigation as a structural commitment: the model writes its full correctAnswer (plus explanation, in that order) BEFORE the learner sees the question; the commitment rides the persisted call args, is revealed on submit, and grades his free text in the model's next reply — the client never grades free recall. - tools.explain setting (segmented 'Quizzing — Multiple choice | Free recall' in Agent settings' Tools group): free arms explain and drops quiz for BOTH agents (prober variant carries no nodeId, same pattern as the probe quiz); mechanics keys never pass filterEnabledTools — quiz stays unwritable (the 2026-09-19 wedge ruling stands) - doctrine lives pi-natively in the tool descriptions (owner ruling — no conditional system-prompt chunks): explain carries the commitment rule; the MC option-building craft moved out of the prompt into the quiz description; shared/20-question-tools.md slims to the quiz-agnostic core - display seams: parseExplainInput (LaTeX-debris restoration included), dock text-mode with an 'I don't know' row (kbd row 0), AnsweredCard reveal (The answer / Why, no verdict chips), [Explain answer] format - phases/plan seams recognize both quizzing tools' nodeId tags; explain answers deliberately feed no ledger evidence (no client grading to key on — a future ruling can parse the model's grade) 1049/1049 tests, typecheck/lint/build green. |

de-meta the system prompts; method leads the composition (owner, 2026-09-27)
The owner's capture-vs-composition check confirmed the wire sends exactly
what composes (byte-identical save the nodeId paragraph ebfe058 had since
changed). This wave removes the implementation meta that leaked into the
prompts and reorders so the method carries weight:
- base: owner's new opener verbatim (install understanding; the
understanding definition — which absorbs the old 'Understanding is
structure' paragraph); Voice moved in from shared/10 (deleted); the
philosophy keeps edge-dependence + logistics ('standard learning'
dropped per owner); intro's two-agents/fragments sentence gone.
- teacher/05-method opens with the owner's methodology bridge ('No other
teaching methods come close') — paragraph 3 of the opener, placed here
so the shared base never points the prober at methodology it doesn't
carry.
- deleted: teacher/60-probing-in-brief (self-evident from shared history;
its mid-lesson mini-probe move salvaged into 20-teaching as one
sentence), the 'Session shape — the durable artifact' section
(extraction-pipeline meta), the fragments-meta lines in shared/20 and
05-method, 'the transcript's seam' phrasing, prober's 'the teacher
that takes over' / 'the handoff is automatic'.
- composition reorder (listSourceSegments): base -> the agent's own
fragments -> shared/ appendix. Teacher method now starts at 12% in
(was 62%); prober doctrine at 34%. shared/20 opens with the owner's
decision rule (quiz only for known-correct-answer, ask for everything
else).
- HANDOFF_TEXT: the owner's user-message version — first-person, paces
the planning (unconditional truths, motivated derivations), ends at
plan_init + accept-or-changes.
Teacher 31.4k -> 28.7k chars; prober 10.0k -> 9.6k. Gates: typecheck 0,
1018/1018, lint clean, build green. (Suite runs 16s; the earlier 10-min
timeout was stale node_modules after master's df1328e 0.87.1 sync —
npm install fixed it.)

fix: verdict death — plan→teach seam inferred from first nodeId-tagged quiz
The Accept/Decline verdict gate is gone (owner ruling 2026-09-26): presenting the plan ends the teacher's turn; the learner's next message is a natural reply. Teaching begins at the first quiz call tagged with a nodeId (probe quizzes carry none) — both folds (view phaseAt3, native phaseAt3Lh) advance on the call itself, and the teach divider renders before that whole assistant block. No backwards compat: verdict markers, the verdict input event, optimistic appends, composer buttons, and projection all deleted; prompts and docs rewritten to the natural flow. |

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

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

Wave A: pi-native tool layer — delete LhTool/toPiTool, TypeBox everywhere, terminate on questions
- src/agent/lh-tool.ts deleted: the zod-wrapped LhTool + toPiTool bridge (z.toJSONSchema per call, clientQuestion flag, hand-rolled result mapping) is gone. Tools are pi-agent-core native AgentTools now. - New src/agent/tool-execute.ts owns what the wrapper added: the abort guard (runWithAbortGuard: run signal + 30s per-call timeout + 250ms grace, 'Operation aborted' / timeout wording preserved), ToolInputError (the retryable '- problem at path' format), result mapping (string verbatim / object JSON / image parts, details rides the record's tool part output), and questionResult() — placeholder + terminate:true (owner Option A: belt of terminate + slim makeQuestionStopper with the clean-question rule; maxTurns deleted from the teaching turn entirely per owner). - All 11 tool files + tools.ts registries converted to TypeBox parameters (typebox@1.3.7, pinned to pi-agent-core's copy). zod refinements (quizInputProblems, askOptionProblems, live-nodeId) moved from schemas into execute — the model sees the same retryable error shape. - question-core + contracts/probe TypeBox-authored (single source shared with the UI); tool-parts parse seam runs the boundary's full chain (Convert → Check → Clean → refinement), fixing the live-smoke lockout: pi's boundary Value.Converts correctAnswer: 17 → '17' but the record keeps raw args, so a parse without Convert rejected a posed quiz (invisible pending question, turn ended). Pinned with the real smoke emission shape. - Subagents converted: demo-builder/researcher AgentTool-native, visual-maker/pdf-reader declaration-only pi-ai Tools with local execute fns, extraction submit schemas re-authored in TypeBox (owner option 2: zod defaults → Type.Optional + fill at the submit seam). - Accepted delta, flagged: TypeBox-native schemas skip pi's JSON-Schema primitive coercion fast path... (boundary still Value.Converts), and prober-quiz unknown keys ride through (Value.Clean strips at display). - Tests: 988 passing (was 967 at the recon baseline); tool-abort and read-tool rewritten against the native seams; question-core/question- tools/tool-parts/demos/web-search/graph-tools/plan-tree/probe-done/ tool-toggles converted to Value.Check/execute pins. Live smoke (PORT=3004, real model): native ls turn streams end-to-end; a real quiz pose (first attempt missing correctAnswer → tool-input-error → model retry → posed) terminates the turn cleanly and persists pending. |

launch message: reasoning before the plan (owner ruling, 2026-09-26)
The probe→teach handoff wake read as a dispatch order ("Author the session's
plan map now") and the teacher skipped the deliberation the planning fragment
asks for. The wake now paces it: take your time, read the assessment and the
probing transcript, reason out the optimal way to teach this person this
thing — floors, ceilings, misconceptions, the minimal tree so every step
lands as obviously true — and only then call plan_init. Machinery honest:
plan_init is still the first tool, the plan map still the first artifact, and
the tail now says to wait for his verdict (which is what presenting actually
does — the old "then begin teaching" tail skipped the verdict seam).

Cost channel cull: the cluster-naming fold dies — two stages, two channels
Off UI's d651f93 flag (displayCostTotals already isolates the display to extraction + audit; the naming stage row and naming runs were filtered out client-side). This culls the server side of the same ruling. THE STANDING RULING, REVERSED BY ITS OWN PREMISE: NamingRunUsage / readNamingRuns / appendNamingUsage were kept at the wave-7 namer kill ONLY because cost-summary's HISTORICAL naming stage read them. With the fold culled, that premise dies — so the whole ledger read path goes too, following the wave-7 embeddings precedent chain: consumer-less ledger seams are deleted, and the on-disk naming-runs.jsonl stays INERT (real trees keep their historical spend bytes; they are simply not displayed anywhere — the same treatment as historical stages.embedding spend). - core/cost-summary.ts: two channels in (chat + notes front doors), two stages out; RecentRun.kind collapses to "extraction" (labels field gone); CostSummaryInput.naming gone; totalDollars = extraction + audit. - ports/store/contracts/config: appendNamingUsage + readNamingRuns ports, store impls + guards, the NamingRunUsage interface, and LEDGER_FILES.namingRuns die. graphRevision no longer counts the file (a smaller revision value is harmless — reads never compare). - components/graph-view.tsx (mechanical, flagged): the defensive .filter(run.kind !== "naming") guards a kind that no longer exists. - Tests: cost-summary's both-channels fold pins; the naming fixtures and the appendNamingUsage store pin die with the seams. |

Context-meter amendment: CONTEXT_LIMITS dies — pi's live catalog is the only limit source
Owner ruling (2026-09-23, amendment to 04e336d): no hardcoded fallback exists anywhere. contextWindow(record, limits) resolves the denominator ONLY from the live index (provider:id -> contextWindow straight from pi's catalog); a model missing from it (historical session, package update, failed fetch) reads limit null and the meter renders usage-only — the honest-render precedent, never a fake window. - src/core/prices.ts: the 1354-entry CONTEXT_LIMITS table (65KB) and its generation apparatus deleted; the fold returns limit: number | null. PRICES untouched (regen verified byte-identical via the reworked sync-pricing script). - scripts/sync-pricing.ts: generates PRICES only; contextWindow leaves the priced map, the guard, and the template. - The dock meter's owner-selected treatment: the activity feed carries the limit server-side. catalogContextLimits() (server/model-catalog.ts) builds the index over the same keyed providers the picker federates; activityFeed() joins it onto every running job (ActivityJob.contextLimit, null when the model is missing — the dock reads it off the feed, no client-side table, no regression while the UI's catalog-join chunk lands). - components/activity-dock.tsx: toBlobs reads job.contextLimit (import of CONTEXT_LIMITS gone); stats-bar renders usage-only on null limit (mechanical interim — UI stream's join chunk follows). - tests: usage.test.ts pins the no-fallback contract (index hit / absent / empty / missing-model -> null); activity-feed.test.ts pins the server join (catalog model -> 1048576, unknown -> null, no-usage -> null); render pins updated to the interim usage-only render. |

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

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

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.

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.

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

feat(models): rolePins on GET /api/models — the background roles' resolved pins
Settings interlude (owner request, 2026-09-19): the route now also returns
rolePins: Record<BackgroundModelRole, {model: {provider, id},
thinkingLevel}> — the six background roles' RESOLVED models (the user's
agent-models override falling back to the config.ts MODELS pin), so the
settings UI shows each role row's 'Default: <actual pinned model>' instead
of a generic config caption. Same resolution the agent factories use
(effectiveSettings), so the caption can never drift from what runs.
Pure projection (rolePinsFor) + the fs wrapper (catalogRolePins); pins
tested against config defaults and model/thinkingLevel-only overrides.
BACKGROUND_MODEL_PINS exported from stores.ts for the test (was local).

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. - Tests: pure-fold suite, naming capture wiring (full importNotes -> naming path), store idempotency + strict reads. |

fix(pdf): split pagesRead from pagesConsulted — the honest badge count
Live-smoke follow-up the user approved (2026-09-19): the GEB read showed
"78 pages consulted" when the reader genuinely READ ~12 - pdf_search hit
snippets inflated the count. PdfResult now carries both:
- pagesRead: extract/render output entered the loop - the honest count
the badge and brief footer show ("read N pages", "Pages read: ...").
- pagesConsulted: every page whose content entered the loop, search-hit
context lines included - unchanged, still the citation audit set (the
reader's instructions still say "Pages consulted: N, N, ..." and the
footer still lists it when it exceeds the read set).
The unread-finish gate deliberately stays on CONSULTED: search hits are
genuine consultation (anti-fabrication duty), so a search-only brief is
honest and must deliver - pagesRead is a reporting refinement, not a
delivery gate. Pinned by the search-only faux test (read [], consulted
[1], delivered).
UI tolerates pre-split persisted records via ?? fallbacks (old steers
lack pagesRead).

feat(T2b): sources v0 — read tool + pdf-reader sub-agent
Learner source files, on the teacher's own terms (nothing auto-injects): - read tool (src/agent/tools/read.ts): pi-read port — path/offset/limit, 2000-line/50KB truncation with use-offset continuation notices, image files (jpg/png/gif/webp/bmp) returned as native image content parts (new LhToolImageResult escape hatch in lh-tool.ts). Always-on in both the prober and teacher registries (user-decided 2026-09). - pdf-reader sub-agent (JobKind 'pdf', toggleable, ack-and-steer): triage via pdf_info (pdfjs text layer: per-page text/image/math-density), targeted pdf_extract, regex pdf_search (hits count as consultation), and pdf_render — pages painted by pdfjs onto a canvas shim in headless Chrome (the pdfium viewer doesn't paint headless), screenshot fed back image-in-the-loop (visual-maker idiom, providerSafePng applied). The unread-finish gate bounces a zero-consultation brief once. Teacher gets a text brief with page citations only; renders never leave the loop. - MODELS.pdfReader = qwen/qwen3.8-flash (user override 2026-09-19: the look-at-renders workload wants the vision-proven model; catalog listed glm-5.3-flash as image-capable but qwen is the known-good daily driver). - UI: PdfCompleteBadge + PdfBriefCard (steer-card, job-card), dispatch card + activity-dock kind entries (type-forced, flagged for UI review). - Prompts: 'Learner source files' section in teacher/30-jobs.md; read line in prober/10-probe-doctrine.md. Doctrine rides tool descriptions per the self-contained-tools principle. |

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. |

feat: extraction coverage — message-granular ledger + token-batched runs (d132373 vision)
THE MESSAGE IS THE UNIT OF COVERAGE (vision-extraction-coverage.md): a per-chat append-only ledger (coverage.jsonl) records which messages the 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. |

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. |

fix: the knowledge-context slider is a discrete 6-stop scale — off, then powers of four from 64
The continuous 0-4096 dial was precision theater (a 128-token budget is ~2 propositions; nobody wants that granularity). Decided stops (owner, 2026-09-15): 0 / 64 / 256 / 1024 / 4096 / 16384 — the native range walks positions 0-5 and maps through GRAPH_CONTEXT_TOKENS_STOPS in contracts. Max rises to 16384 (route range follows); the server still accepts any integer in range so a stale client cannot brick settings; non-stop legacy values snap to the nearest stop for the thumb, readout stays honest. |

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.

Semantic topic clusters: local embeddings replace Louvain
Louvain only ever found the reasoning chains (the graph is disconnected by nature — every connected component became its own cluster) and edge-orphans could never join anything. Clusters are now RELATED TOPICS: propositions grouped by meaning. - Embedder (src/server/embeddings.ts): in-process transformers.js v4 running EmbeddingGemma-300M q8 (MTEB 68.4, ~300MB one-time download), MRL-truncated to 512d, "title: none | text:" prefix on 100% of inputs, L2-normalized so cosine = dot. Model/dim mismatch voids the ledger (full re-embed). Injected at the composition root — the agent layer never imports the server layer (architecture law). - Ledger (data/graph/embeddings.json): model + dim + vectors + the persisted cluster partition. Reclustering runs at the END of every embedding batch (post-merge hook, both front doors) — never per read (the agglomerative pass is ~1.5s at 338 nodes). - Clustering (src/core/semantic-clusters.ts): hand-rolled average-linkage agglomerative over cosine (npm HDBSCAN is an abandoned alpha). Stragglers stay singletons by default; attachStragglers is the all-in toggle. Threshold 0.60 swept on the real graph: 26 topics, 74/90 edge-orphans land in real topics, 10 stragglers. - Consumers (snapshot, settle, namer, replay) read the persisted partition — one cluster concept everywhere; core-survival label matching unchanged (20/26 topics kept labels). - Louvain retired: detectCommunities + graphology* deps deleted (graphology-louvain had leaked into the client bundle since the clusters wave); scripts/bench-graph.ts (dead FA2 bench) removed. - scripts/embed-graph.ts: backfill/cold-start (338 nodes in 150s including the one-time model download). |

Option A: incremental anchored force layout, persisted server-side
The layout now EVOLVES instead of reshuffling on every extraction. A pure
core module (src/core/layout.ts) warm-starts forceAtlas2 from the positions
ledger (data/graph/positions.json, read-modify-write like sources.json,
updatedAt stamp for future live-physics conflict handling), re-blends every
previously-positioned node toward its anchor each iteration (retention 0.85
- old placements stay recognizable, strong forces still win), seeds new
nodes near their positioned neighbors, and seeds orphans on the rim outside
the core so they read as unconnected knowledge.
- Port/store: GraphStore.readPositions/writePositions; snapshot carries
positions when the ledger exists (optional - fresh graphs unchanged).
- Extraction pipeline settles synchronously after every merge (chat and
notes paths), before usage persist - the next /api/graph fetch already
reflects new nodes.
- View: the ledger IS the layout; the local one-shot FA2 pass survives
only as a fallback when no ledger exists.
- scripts/replay-layout.ts: simulates organic growth by replaying the
current 338-node graph one imported file at a time (real import order,
edges activate when both endpoints exist). Real run: 338 positions in
0.3s, 90-degree-0 orphans collecting at mean r=338 vs connected r=194.
- Also restores the cluster region fills (hull background colors) that

Clusters phases B+C: labeling records, the naming call, snapshot payload
Core-survival labelings (vision section 1, DECIDED 2026-09-13): ClusterLabeling records in a new append-only ledger (data/graph/cluster-labels.jsonl), immutable, id = clu_ + sha256 of the sorted core so re-naming races and re-runs dedupe at the store seam. matchClusterLabelings (core/clusters.ts, pure): a community keeps a record's label while at least half its core survives in it; both sides single-successor (a split keeps one name; greedy by overlap, ties to the newer record). The namer (src/agent/subagents/cluster-namer.ts): ONE singular cheap LLM call (new 'labeler' role, glm-flash/low) names every new/changed community at once, given member names + statements (capped at 12 members per cluster). refreshClusterLabels runs POST-EXTRACTION (user-decided) from both front doors, fire-and-forget — naming failure never fails the run; refreshes serialize behind a chain so parallel imports never mint duplicate labels. import-notes.ts awaits clusterNamingSettled before exit. Payload: GraphSnapshot.clusters (>= MIN_CLUSTER_SIZE 3) joins detection with labelings at read time — claimed clusters carry the record's label and id; unlabeled ones carry a member-hash id and null label. Detection is deterministic so no memo in v1 (ms at current scale; revisit at vault scale). Tests (372/372): matcher half-rule/split/merge/greedy/tie cases; naming end-to-end through importNotes (one call, one record, claim on re-refresh), naming failure non-fatal; snapshot derivation with labeling join; 11 test pipelines now pin an explicit labeler seam. |

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).

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.

feat: custom message types for system turns — wake and verdict messages
The custom-message scheme (user-decided 2026-09-12): system-authored
user-role messages are NOT human messages — they carry marker data parts
only, the adapter owns their model-facing wording, and the UI renders
them under control. Nothing fake is ever persisted as human speech.
The inventory (all migrated):
- probe→teacher handoff wake: was a text-bearing user message rendering
as a fake user bubble; now data-probe-handoff marker-only — the
adapter flattens it to HANDOFF_TEXT (core/contracts/chat.ts), the UI
renders a quiet 'Preparing your plan…' system line.
- plan accept/decline: was boilerplate text ('The plan is accepted…',
'I'd like the plan revised…') masquerading as learner speech — the
decline wasn't even marked; now data-verdict {accepted, at} on its own
message, adapter flattens to verdictText(), UI renders the quiet
verdict marker ('✓ Plan accepted' / '↻ Plan revision requested').
sendVerdict sends TWO REAL MESSAGES when the learner typed a note
(the note as a genuine user message, then the verdict) in ONE turn
via setMessages + sendMessage() — no 409 dance, no double teacher turn.
- sub-agent steers: the abort steer gains its data-subagent-aborted
marker part; the UI keys steer rendering off PARTS (artifact/aborted),
not metadata — metadata stays as pump mechanics only.
- record-adapter: systemTextOf() flattens marker-only messages; steers
keep their text (payload — briefs are content, not boilerplate).
phases.ts: plan→teach advances on data-verdict{accepted:true} only;
learner text alone can never sanction teaching (pinned). data-plan-
accepted retired, no back-compat (user-decided: wiped-data doctrine).
Pinned: record-adapter.test.ts (verdict/handoff flattening, note+verdict
order, steer payload kept, UI-only parts skipped), phases.test.ts
(verdict marker semantics, out-of-order, text-never-fakes), jobs.test.ts
(abort marker part), demos.test.tsx (badge renders off the part, not
metadata).
Live GLM smoke (disposable driver, deleted): probe→conclude→wake→plan→
decline-with-note (revised, still plan)→accept-with-note (teach) — ALL
CHECKS PASS, including marker-only handoff/verdict on the wire and zero
fake human speech in the transcript.
Gates: tsc, lint, build, 335/335.

fix(arch): parse, don't cast — the UI parse seam for model-authored input
The architectural answer to the validation-crash question: validation IS
first at the model-facing boundary (pi validates arguments before
execute; failures return to the model same-turn — all three live
incidents retried successfully). But the same bytes also exist UNVALIDATED
by design in two other places: the live wire streams raw tool-input
deltas DURING generation, and the transcript keeps the raw input of
REJECTED calls (honesty + the replay invariant). The consumers were
supposed to trust part STATES — but that trust was enforced by
TypeScript casts ('part.input as X'), which are compile-time lies with
no runtime check behind them. That is the hole both crashes came
through, and it should not have been possible.
The structural rule now: model-authored INPUT is consumed only through
parsers running the SAME zod schema the model faced — boundary-valid ⇔
consumer-parseable, mechanically. Server/learner-authored OUTPUT stays
trusted (our code authors it).
- src/core/tool-parts.ts (new): parseQuizInput (display parse over the
shared quizInputBase — strips the teacher-only nodeId, accepts both
prober and teacher boundary shapes), parseAskInput, parseProbeDoneInput.
- contracts/probe.ts: probeDoneInputSchema is now core-owned zod — the
probe_done tool declares it (single source of truth), the seam runs
the literal same schema.
- question-dock.tsx: the dock parses its input at entry; unparsable
renders the quiet malformed-question fallback, never a crash.
- probe-done-card.tsx: the input preview goes through the parse; the
old state reasoning and shape guards collapse into it.

Swap the server engine to pi-ai/pi-agent-core (Band B+C of docs/pi-engine-swap.md)
The Vercel AI SDK survives only as Band D (useChat client + UIMessage
record types); @openrouter/ai-sdk-provider is uninstalled.
- src/agent/models.ts: PiEngine {model, streamFn} via createModels +
openrouterProvider subpath; thinkingLevelFor maps config effort none->off
- src/agent/lh-tool.ts: neutral LhTool (zod authoring, optional execute,
clientQuestion flag); toPiTool converts via z.toJSONSchema and re-runs
zod inside execute so refinements ride the error-result retry path
- src/server/pi/record-adapter.ts: UIMessage records -> pi Messages
(dangling tool calls get synthesized interrupted results)
- src/server/pi/ui-stream.ts: SSE bridge emitting AI-SDK-shaped chunks so
the useChat client parses unchanged (continuation id rule, question
tools never emit output, tool-input-error for bad authoring)
- teacher-agent.ts: stateless per-turn pi Agents; shouldStopAfterTurn
stops only when every question-tool call resolved cleanly (errors retry)
- chat-handler.ts: buildAgent(outgoing) factory seam (stateless doctrine);
assertValidUiMessages owns the retired SDK validation gate
- sub-agents via shared runSubagent (pi-run.ts); extraction stages stop
after a clean submit; visual-maker keeps its hand-rolled loop over
direct streamSimple calls; aborted model calls bill no usage
- tests: all model seams ported to pi-ai faux provider (scripted
FauxResponseSteps, agent factories); handleChatRequest second param
is now an agent factory
Gates: tsc, lint, build, 305/305. Live GLM smoke (disposable driver,
deleted): prober streaming + persistence, question seam, turn-2
continuation same message id, per-turn real token usage - ALL PASS.
Data wiped at the pivot (chats/graph/jobs, .gitkeeps kept).

feat: the plan verdict gate — acceptance is the plan→teach seam
The accept-plan UI lands (docs/probe-teach-split.md §4, formerly the interim rule): presenting the plan no longer moves the phase — the learner's ACCEPT does. While the presented plan awaits its verdict, the composer's send square becomes two stacked buttons (green Accept plan / red Decline); typed text rides the verdict as his note, Enter keeps sending plain side questions (phase unmoved), decline asks for a revision and the buttons stay. The seam: accept sends a user message carrying a data-plan-accepted part (PlanAcceptedData in contracts/chat.ts, TeacherUIDataParts 'plan-accepted'); phaseAt3 reads it as the plan→teach event (plan_init demoted to presentation-only); convertToModelMessages drops data parts, so the teacher sees only the text. Mid-lesson rewrites need no fresh verdict — acceptance happens once, at the first presentation. The teacher's planning prompt now ends the turn at presentation and waits for the verdict (never teaches into an unaccepted plan). Gates: tsc clean, 304/304 (phases tests rewritten to the acceptance seam incl. decline/side-question/failed-init cases; composer verdict render tests), lint, build. Live GLM smoke ALL PASS: phase pinned at 'plan' after plan_init, presentation turn carried NO check, accept click flipped the summary to 'teach', then tagged checks moved the map (current=rates, visited=composite); zero console errors. |

feat: probe/teach agent split — explicit phase markers, position-only plan map
Diagnosis (2026-09-11 user testing, minimal-effort GLM): sessions stuck on 'plan' forever. Two causes: (1) the three-phase view read the stored tree's currentNodeId, which nothing ever writes post author-once (2026-09-03) — a structural dead seam; (2) the teacher stochastically left quiz.nodeId untagged, and done-by-quiz-result semantics would have falsely completed nodes anyway. The redesign (docs/probe-teach-split.md) abolishes derived occupancy in favor of explicit events: - Two agents over one transcript: createProberAgent (quiz without a nodeId field, ask, probe_done) and createTeacherAgent (full toolset, plan_init onward). The chat-handler construction branch keys on a probe_done part in the transcript. MODELS.prober added. - probe_done: server-side seam tool — carries the learner assessment (strands + free-form edge read), refuses while a question is open or the probe is already concluded, and queues a handoff steer through the generalized wake pipeline (steers now dedupe by id, not jobId; job finalization only for job steers). The teacher auto-wakes and authors the plan; the learner sees the assessment via the probe-done card. - phases: probe ends at a concluded probe_done, plan ends at a successful plan_init — strictly sequential, no skipping, no legacy compatibility (data wiped at the pivot per doctrine). - Plan map = position, not completion: derivePlanStatuses reads only tagged quiz CALLS (state/outcome feed nothing); current = latest tagged node with consecutive duplicates collapsed, visited = earlier distinct stays (a revisit stays in both — current wins at render). PlanTree is structure-only; currentNodeId/doneNodeIds and the dead mutation helpers are gone. No fallback current. - Prompts split per agent (prompts/prober/, prompts/teacher/ over the trimmed shared base); graph-context injection removed entirely (shelved, docs/probe-teach-split.md §5); knowledge-graph context no longer reaches either agent. - Plan blocks are full-only snapshots at plan_init (neighborhood machinery retired; the persistent DAG window is the future UI wave); usage capture unchanged. Gates: tsc clean, 294/294 tests (phases/plan-tree/plan-blocks/question- tools rewritten to the new semantics; probe-done + handoff-wake tests added), lint, build. Live GLM smoke PASS: prober concluded with an honest assessment, teacher auto-woke, authored a 10-node plan with the block attached, then tagged checks on slope-instinct → secant derived current/ visited exactly as designed; grading honest both ways (driver off-by-one proved a wrong answer grades false). |

Fix turn-usage keying: idempotent per request turn id, not messageId
Live smoke exposed two bugs in the turn usage log: - onFinish messages carry no ids (withMessageIds fills copies inside persistTurn), so fresh turns keyed messageId "" — provenance lost. - The SDK coalesces continuation turns into ONE response message (a whole probe conversation lands in a single assistant message), so per-messageId idempotency swallowed every continuation turn's usage. TurnUsage gains id: string (unique per request, the append idempotency key); messageId stays as transcript provenance, taken from the id-filled list. appendTurnUsage dedupes by id; continuation turns with the same messageId each keep their usage. |

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

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. |

feat: abort sub-agent jobs (real kill) + runner usage capture into JobRecord.usage
Wave 4 (agent-side observability + control), reconciled with the dock contract (master relay 2026-09): - abortJob in src/server/jobs.ts, exported through the server barrel for POST /api/activity/abort (master's thin route): fires the job's AbortController (real kill — the in-flight model call aborts, not just the next loop check), drops any queued result steer, flips the record to error "Aborted by learner" + activity "aborted" synchronously, and queues a one-line abort steer (buildAbortSteer) through the same wake pipeline so the teacher's promise doesn't hang in the lesson. Shares the result steer's deterministic id space, so abort + racing result can never both deliver (steerDelivered dedupe). - Abort registry (src/agent/subagents/aborts.ts) on globalThis, mirroring the wake pipeline's module-state pattern; runner registers/unregisters per run, so the route's module instance sees the loop's controller. - Runner usage capture: LoopContext (abortSignal + onUsage) threads into all three kind loops; per-step usage folds via accumulateJobUsage into JobRecord.usage (model from config MODELS, absent-never-zero), flushed in runJob's finally so an aborted job's money record survives the kill. - Contracts: JobUsage token fields optional + lastStep (most recent call's accounting, for the dock's per-blob context line vs CONTEXT_LIMITS); SubagentResultMeta.aborted; AbortSteerMessage; buildAbortSteer; SteerMessage union generalized. - demo-builder/visual-maker accept abortSignal + onUsage (visual folds generateText usage per iteration). - stillRunning/finishJob/jobContext guards: an aborted job is never overwritten by the runner (terminal no matter what the wake does); failJob and the pump's finalizeJob keep the flip. - UI: abort steer renders a quiet aborted chip (job-aborted-badge). - Prompt 20-jobs.md: one line about aborted jobs. Tests: accumulateJobUsage folds (undefined-preservation, lastStep), runner usage capture, real-kill abort (sync flip, silent unwind, abort steer wakes), usage-so-far survives the kill, aborting a delivering job drops the queued result steer, outcome reasons, abort-chip render. 330/330, typecheck/lint/build green. |

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. |

Merge feat/sub-agents: author-once plan protocol, steer-delivery starvation fixes, research-steer affordance
Wave 3: the plan protocol collapses to one re-callable mermaid plan_init (seven mutation tools deleted by design; statuses derive from quiz checks; live quiz-nodeId validation with mid-turn retry). The steer-starvation arc: steers deliver coalesced with the learner's answer (claimSteers), persist dedupes same-id continuation copies, jobs settle-sync defers while a turn is busy. Research steers gain the collapsed full-brief affordance. Model reasoning effort set to minimal across roles. |

fix: steer-delivery starvation — continuation coalescing (claimSteers)
The bug (seen live): a teacher that ends every turn with a new pending quiz keeps the wake pipeline's idle gates permanently closed — the steer sits in 'delivering result' forever while the learner answers check after check. - claimSteers (server/jobs.ts): the chat-handler claims every queued, undelivered steer the instant a client turn wins the turn registry, and appends it after the learner's answer — conversion-safe, the answered quiz carries its output. Every answer flushes pending steers immediately. - The pump keeps its post-idle duplicate-guard (re-check steerDelivered before firing), so a claim racing the pump converges to exactly one delivery either way. - The stale-job sweep now skips chats with a turn in flight (a healthy but slow wake no longer gets falsely re-queued as 'recovering'). - Out-of-lane surgical touch (flagged for master review): the 3-line handleChatRequest seam (claim after beginTurn, persist+stream 'outgoing'). - Verified live end-to-end on the stuck session: answering the pending quiz fired the steer + wake turn within a second; job flipped done/delivered. |

Author-once plan protocol: single mermaid plan_init + derived statuses + live quiz nodeId validation
- plan_init is now the ONLY plan tool: a mermaid 'graph TD' block parsed by a constrained-subset parser (mermaid-plan.ts) with line-precise errors; the seven mutation/tracking tools are gone by design (2026-09-03 design pass). - Re-call plan_init = sanctioned wholesale rewrite; slugs are permanent. - derivePlanStatuses (contracts/plan.ts): done = passed check tagged with a quiz nodeId; current = open check's node else first topo-ready node — the tracking the teacher no longer declares by hand. - questionToolsFor(ctx) (tools.ts): the quiz schema chains a dynamic plan- nodeId validation against the LIVE record — an invalid nodeId is rejected at the call boundary and the teacher retries mid-turn, before any UI. Static questionTools stay validator-less for the default path. - Prompts rewritten for mermaid authoring + derived position. - Out-of-lane surgical touches (flagged for master review): src/core/question-core.ts (quizInputObject export + nodeId description), src/core/contracts/plan.ts (derivePlanStatuses + doc). |
