- Settings ▸ Graph grows the embedding-model picker (graph-row-embedding-model):
GET /api/models/embeddings' live-federated BYOK catalog (re-fetched on mount
and every settings save), rows priced from EMBEDDING_PRICES ("$x.xx/1M in",
honestly "—" when unlisted), ids shown AND stored as full colon-safe slugs
(openrouter:liquid/…:free is never split), plus an Unset row writing null.
Empty catalog = nothing keyed: the trigger BECOMES the deep link to Keys
("Add a provider key first…") — and deep-links fired while the dialog is
open now actually switch sections (initialSection was read once at mount;
the body follows it now — pre-existing gap, first exercised by this link).
- Re-embed gate (owner design): picking a model that differs from the stored
one holds the write behind a confirm strip carrying the honest node count
from GET /api/graph; zero propositions skip the strip (nothing to re-embed)
and land directly. Unset never confirms — the port just stops resolving.
The copy says the re-embed runs with the next background pass (the staleness
machinery — a settings PUT alone never triggers it; no server endpoints
were added).
- Gray-out, the searchStatus precedent: with no model configured, the ladder
rungs Embedding/Clustering/Labeling dim + disable with a "Needs an
embedding model" hint (master switch stays lit), and the stats-bar
GraphContextControl swaps its slider for a dimmed deep-link button to the
Graph section. Loading never grays; every settings save re-reads (signal).
- Cost chrome: the pipeline popover grows the Embeddings stage row
(costs.stages.embedding, wave 6's folded stage — "— · 0 in / 0 out" until
runs exist, same as its siblings).
- Master's ride-along: the core-barrel ChatDeleteMode comment now says two
type-only things (it always exported both).
Gates: tsc clean, 912/912 (8 new: price lines, model-dependency predicate,
unset/set SSR dimming; 2 ladder fixtures updated to the new no-model
semantics), lint 0, build ok. Live-verified on :3001: unset deep-link →
graph section, menu pricing + colon-safety (37 options), confirm strip with
"20 propositions", Cancel keeps the record, Unset writes immediately,
in-dialog empty-catalog deep-link lands Keys, Embeddings row in the popover.
- MenuShell: after placement, focus lands in the search when the menu has
one, else the body (tabIndex -1) — the lists' mount-time focus ran during
the hidden measuring pass and silently failed, so no dropdown ever opened
focused. The body owns the arrow machine for searchless menus:
ArrowDown/Up cycle options with wrap (first/last entry from the body,
native-select convention), Home/End, Enter activates, preventDefault so
arrows never scroll the page.
- Appearance: the CSS-var applier only ever setProperty'd — a later write
omitting a var left the stale inline value forever (empty background
never reset, serif toggle-back looked dead). appliedNamesRef tracks what
was set; staleVarNames (pure, exported) returns what to removeProperty.
- CommitInput: controlled — after a commit the field snaps to the stored
record, so the clamp on a -5 prose size is visible (12), Esc reverts.
- Keys: Add-provider dropdown closes on pick; the paste row is inline
(label | input | Save | Cancel); existing-row editors go inline with an
explicit Cancel beside Save/Delete — folding is visible, not Esc-only.
- Graph context: readout is content-sized (tabular-nums) — no fixed-width
dead gap when "off"; the dictation strip fills whatever space remains.
Gates: tsc clean, 866/866 tests (new staleVarNames suite), lint 0, build ok.
Live-verified via Playwright: dropdown focus+arrow cycles+wrap+Enter pick,
background set→empty reset, serif round-trip, visible clamp to 12, provider
pick closes menu, inline editor + Cancel + Esc fold, slider width 270→277px.
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.
The original vision, restored (owner, 2026-09-15): pre-chat the session-
data side of the under-composer stats bar is free real estate ("—" only),
so the budget slider mounts exactly where session data will sit once a
session exists — via a new StatsBar leftSlot — vertically centered with
the model + thinking pills by the row's own geometry. Short 96px slider
instead of a full-width one; readout abbreviates "1k tok" so >1k budgets
stay on one line ("4.1k tokens" wrapped). Home and /chat/new both.
One shot per chat, fired at the first turn's onFinish: the session's
topic (its only typed message) is embedded as an EmbeddingGemma retrieval
query; the semantically closest graph propositions are selected under the
session's token budget (pure budget, no similarity threshold — the
decided doctrine) and delivered as a marker-only steer through the wake
pipeline, queuing behind pending questions like every sub-agent result.
- contracts: ChatSettings.graphContextTokens (default 1024, max 4096,
step 128, 0 = off); GraphContextData + graphContextText; the
graph-context JobKind + buildGraphContextSteer (id steer_ctx_<chatId>)
- core/graph-context.ts: brute-force cosine top-K, greedy chars/4 fill
under budget, most-recent UnderstandingLevel fold, count cap 64,
parse-don't-cast at the marker seam
- server: embedQuery (role-asymmetric query format, same warm singleton
— vector-space parity by construction); the runner (startGraphContext-
Injection one-shot gates; runGraphContextJob validates ledger parity);
wake branches (chatIdOf/jobIdOf, finalizeJob done, recoverStaleJobs
re-deliver or contextRespawn); abortJob kills context jobs SILENTLY
(nothing was promised in the lesson); turn-service trigger seam
- adapter: data-graph-context flattens to the canonical block (malformed
parts have no model face)
- UI: the budget slider (home dock + /chat/new draft, the session-data
strip); the quiet SystemLine "~537 · 10 propositions"; dock kind
"Knowledge context"; model-picker PUT now spreads settings (a model
pick can no longer clear the sibling override)
Live-smoked end to end on the real embedder + real GLM: seeded ledger
(10 propositions), session on "modal logic: possible worlds and the
necessity box" — job in the dock, queued behind the prober's question,
delivered on the answer, SystemLine in the transcript, wake turn reads
the block and continues the probe. Gates: tsc, lint, 459/459, build.
