amosblomqvist af666aaa3f physics: bundles join their cluster; depth runs over the logical graph
Owner-approved brief (orchestrator, physics arc): two laws.

1. IMP-NODE CLUSTER ASSIGNMENT. Imp nodes were unclustered (the partition
   runs over stored propositions only) — no centroid pull, outside the
   painted hulls, bundles sitting on the periphery pointing outward.
   Now: a derived imp node's cluster is a function of its derivation —
   MAJORITY among its PREMISES' birth sessions (owner: premises, NOT the
   conclusion), ties to the chain's OWN birth (its provenance's first
   point — the asserting session; deterministic, coincides with the
   unanimous common case). Imp nodes are always re-derived, never
   birthed, so the assignment must be exactly this.

   Seam chosen: core/session-clusters.ts exports impClusterKey + a
   shared attachImpToCommunities that mutates a communities list's
   members IN PLACE. graphSnapshot attaches AFTER the hull filter (a
   2-proposition community + its bundle never resurrects a hull — the
   filter counts propositions); settleGraphLayout attaches to the
   unfiltered partition (settle pulls every community; hulls are a
   canvas-only concern). Both cluster-membership consumers — the sim's
   centroid pull and buildRegions' rasterization — read it through the
   members lists that went through the one helper, so the resting
   ledger and the live sim agree on where bundles belong.

2. DEPTHS OVER THE LOGICAL GRAPH. inferenceDepths ran Tarjan over the
   DRAWN edges (premise→imp→conclusion), inflating every multi-premise
   conclusion one hop (depth(imp)+1 instead of depth(premises)+1) and
   ranking the geometry point itself. Now:
   - deriveView additionally emits logicalEdges — every chain contracted
     to direct premise→conclusion arrows over PROPOSITION ids only
     (per-premise, deduped — a conclusion's rank is max over premises,
     which a single arbitrary premise edge could not express).
   - GraphSnapshot carries logicalEdges; createGraphSimulation /
     incrementalLayout accept a logicalEdges option: the depth
     machinery (orphan detection AND the rank pass) reads it, springs
     keep the drawn edges. Absent = edges (legacy behavior).
   - Imp nodes join the ORPHAN-EXEMPTION mask explicitly — never pinned
     to a level, keep the full regular forces (gravity, cluster pull,
     springs), settle naturally between premise and conclusion levels;
     the rank map is computed over propositions only, so arg_ ids are
     absent from it by construction.
   Wiring: settle + canvas (CanvasData.logicalEdges → buildSim) +
   replay-layout all pass the logical set.

   EXTRA FIX (in-slice discovery, one line, graph-server domain):
   server/graph.ts graphClusters — the practice picker's /api/graph/
   clusters — partitioned snap.NODES (the canvas image, imp nodes riding
   it since chains-primary), leaking arg_ ids into nodeIds: pickable ids
   that silently vanish inside chainsForSelection while nodeCount lied.
   Now partitions snap.propositions — same purity law as the chain
   table's 767a559 fix.

Tests (+13): impClusterKey pins (unanimous; cross-session majority; tie
→ chain's own birth, not the conclusion's); attach pins (members gain
the imp id, sorted; single-premise attaches nothing — no node exists;
dangling mints nothing; home absent from the list stays unattached);
snapshot pins (imp id rides cluster members to both consumers; the hull
filter counts propositions); logical-depth pins (multi-premise
conclusion at premises'+1 NOT +2; imp absent from the rank map);
depth-force exemption pin (rows pin crisply, arg_x floats unpinned —
old behavior stamped it onto the conclusion's row); deriveView logical
arrows (per-premise, deduped, proposition ids only).

amosblomqvist 4985b6f9fa chains-primary: stored chains replace typed edges; edges become a derived view
Owner rulings 2026-09-30: reasoning chains are the stored truth; the graph
canvas renders a lossy derived image. No migration, no backcompat — old
graph data was wiped.

- contracts: GraphChain (arg_-minted id, premises, conclusion) replaces
  typed edges; GraphEdge survives only as the untyped derived arrow;
  GraphSnapshot carries stored chains; supports edges retired entirely
- store: chains.jsonl ledger (edges.jsonl purged at load alongside legacy
  events.jsonl); readChains/appendChain seam; merge dedupes by
  (sorted premises, conclusion), re-assertions append under the same arg_ id
- core: deriveView mints implication nodes (name ⟹, statement via
  formatChainLine) plus premise→imp→conclusion arrows; clusters stay
  proposition-only (birthSessionPartition); chainsForSelection now groups
  STORED chains (chain rides iff every member selected) — independent
  arguments for one conclusion never union; chainsToGraph/chainsToEdges die
- extraction: extractor submits chains natively (expandFindings deleted);
  auditor receives propositions only; supports fan-out gone
- deletion: full death of a proposition kills every referencing chain;
  arg_-prefixed node deletes kill that chain; chainsRemoved stats
- UI: every arrow renders the ⟹ double shaft; supports toggle + thickness
  slider and detail-card edge sections deleted (card keeps name +
  proposition); chain table + practice pipeline read stored chains
- tests: 1188 green across the new seams

amosblomqvist 8355fbabdb 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

amosblomqvist d1b46132b9 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.

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 f5edc7f0a5 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).

amosblomqvist 3a1c18b9de Inference-depth anchoring playground: vertical + radial modes
The graph's follows/supports edges encode derivation (premise ->
conclusion); the layout can now express that rank spatially, as a
session-only playground toggle (nothing promoted yet):

- inferenceDepths: longest chain from a base node, CYCLE-SAFE by
  SCC condensation (Tarjan, iterative) — the DAG property is typical,
  not guaranteed; cycle members share their component's depth (mutual
  support = equal footing). O(V+E), pure, deterministic.
- DepthAnchor force: per-node target scalar — vertical mode rows
  (baseline at the anchor centroid, arrows up), radial mode rings
  (foundations center, outer boundary = edge of knowledge). The rank
  is computed, not simulated: pairwise up-forces can't give baselines.
- Mode projections: gravity x-only in vertical / dropped in radial;
  cluster pull x-only in vertical / tangential-only in radial; the
  anchor re-blend preserves user arrangement in the FREE dimension
  only (x / angle) — meaning owns the constrained axis, memory owns
  the free one.
- setPhysicsTuning reheats (alpha 1): toggling a mode re-forms the
  graph live and commits the new rest state; drag release is springy
  along the constrained axis (node returns toward its level/ring).
- Sweep on the real graph: strength 0.8 = 215/216 arrows correct with
  organic sag; 1.5 = crisp rows. 174 base nodes, max chain depth 7,
  zero cycles in current data. replay-layout --depth=<mode> bakes a
  mode into the ledger for rest-state experiments.

amosblomqvist 975a78a304 Cluster gravity: per-cluster centroid pull force in the engine
The 'virtual node' realized as a centroid force: two allocation-free
O(n) passes per tick (membership resolved once at sim creation;
Float64Array sums). Measured indistinguishable from force-off at 338
nodes (271ms vs 272ms per 400-tick settle).

- createGraphSimulation: SimOptions.clusterPull + linkStrength +
  velocityDecay (physics controls plumbing); degree-scaled link
  stiffness so linkStrength=1 is exactly d3's default
- settleGraphLayout split into layout-settle.ts (it computes the
  Louvain partition for the pull); layout.ts stays browser-barrel-pure
- barrel no longer re-exports clusters.ts: graphology + louvain are
  fully out of the client bundle (verified against built chunks)
- replay passes the per-batch partition; CLUSTER_PULL_STRENGTH=0.15
  tuned by sweep: cluster spread 63->36 world units, centroid
  separation and total span unchanged (no blob merge, no collapse)

amosblomqvist 7eceb58303 Engine unification: d3-force replaces forceAtlas2 everywhere
One engine owns the equilibrium: the merge settle and (next commit)
the live drag both run createGraphSimulation — d3-force link springs,
1/d charge, weak centroid gravity — so a drag's rest state IS the
server's rest state. The FA2-era anchor mechanism survives as a
post-tick POSITION-SPACE re-blend (retention 0.85): d3's forceLink is
a Hooke spring (strength*(d-L)*alpha), which overpowers any force-space
anchor at long range — the re-blend is alpha-independent and always
wins as the sim anneals (the 675-unit drift bug). Gravity retuned for
d3's 1/d many-body falloff (bootstrap 0.2 / incremental 0.12: cluster
spacing lands ~400 world units, the FA2-era density). Rim orphans seed
(and anchor) at 1.7x the CONNECTED core's mean radius — a max-span-based
rim fed back on itself and ran the layout away to 6000 units. Replay:
338 positions in 1.6s, old-node shift within a batch 4.8 (FA2: 23).
2026-09-13 09:17:01 +03:00
amosblomqvist 0c14ea425d 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
  6692b19 had removed on a misreading of "no glow".

Live-verified: fit zoom derives from the ledger bbox, pickAt aligns with
ledger positions at every probe, hover/click/detail-card work, 408/408
tests, typecheck/lint/build green.

Future live physics stays cheap by design: the same pure function is the
merge-time settler and the future client simulator; a pinned node is just
an anchor with full retention.
