* ui : add browser-style conversation tabs store
Track open conversation tabs in order, persisted to localStorage and
pruned against the loaded conversation list on init. The chat layout
syncs the route's tab on every navigation, so any way of reaching a
conversation opens a tab for it.
* ui : add temporary new-chat tabs
New-chat tabs are unsaved conversations carrying a temporary id used
directly as the route (#/chat/<id>). They live in memory and are only
persisted to the database - keeping the same id so the route and tab
stay stable - when the first message is sent. Deleting one drops it
without confirmation, and deleting conversations now closes their tabs.
* ui : render conversation tab bar in chat layout
Desktop-only tab bar above the chat screen, one tab per open
conversation or new-chat tab. The active tab follows the route id;
clicking navigates, middle-click or the close button closes (switching
to the left neighbor), and a trailing + starts a new chat. Tabs appear
only on chat-id routes; the bare #/ new-chat view has none. The bare
route stays put unless a prompt/model deep-link routes it to a new-chat
tab.
* ui : route new-chat entry points through tabs
The sidebar New chat item, Cmd+Shift+O, the search page and the
arrow-key fallback now open a new-chat tab instead of navigating to the
?new_chat URL, which is removed. New chat is no longer a special route
but a tab like any other conversation.
* ui : track sidebar expanded state in a shared ui store
Move the desktop sidebar expanded/collapsed state out of deviceStore into a
dedicated uiStore so the chat tab bar can react to it.

* chat : add browser-style conversation tabs with a new-chat screen
Track open conversations as tabs above the chat, one per open chat, plus a
single New chat tab for the bare `#/` route. New chat is just the `#/`
screen - no temporary conversations - and its tab is dropped when navigating
away. Sending the first message creates a real conversation and opens a tab
for it.

Assisted-by: pi
* ui : keep the new-chat tab across reloads and fall back on close

when Conversation tabs are off

Assisted-by: pi
* ui: fix routing nits
* chore: Update doc comments
* refactor: Mark fire-and-forget openNewChat calls as `void`
* chat: fix the deep-linked prompt, the tab width and the tab shortcuts
The chat start page creates the conversation and hands the prompt over
to the chat route, which still sees it in the query string. Sending it
on both sides queues the second copy as a pending message, which shows
up as a stray user bubble once the answer lands and vanishes on reload
since it never reaches the database.
The tab bar takes the max width of the collapsed sidebar while it is
expanded, and the other way round.
The tab list is pruned against a snapshot of the loaded conversations,
so a conversation created while that list is still loading loses its
tab even though the route just opened it. The active tab then falls out
of the list and the cycling shortcut jumps to an edge on every keypress
instead of moving one tab over. Tabs synced from the route are kept as
they are, only the persisted ones are pruned.
The rich chat input claims ctrl or alt with shift and an arrow for its
badge-aware word jump, which now belongs to the tab cycling shortcut.
Holding shift hands the key combination over, the plain word jump is
unchanged.
The close-tab shortcut consumes the event before checking whether the
setting is on, and the logo background loses its importance flag.

* fit: also take into account n_streams
* server: make the draft context follow the target context
With a non-unified KV cache the target context now holds n_ctx_train
tokens per sequence, while the draft context was still created with
n_ctx = 0 and fell back to n_ctx_train / n_streams per sequence. A slot
filled beyond that point makes the draft batch fail to decode, and the
server answers 500 on the request.
The draft context now takes its size from the target context, so both
hold the same number of tokens per sequence. Contexts that share their
cells with the target no longer need the kv_size override.
The memory reserved for the draft model before fitting is measured at
the largest context the target can take, since the draft context grows
with the target and a fixed byte margin cannot express that.
* fit: take an optional second model into account
Illustrates the alternative discussed on the draft context fix. The
memory of a draft or MTP context is currently handed to the fit as a
fixed byte margin, which cannot express a memory that grows with the
context the fit is still deciding on.
common_fit_params now takes an optional second model that shares the
devices of the main one. Its context follows the main context and its
memory is measured again whenever that context changes, so the reduce
path stays exact instead of conservative. A model that cannot be
measured on its own, such as a shared cell MTP context, is skipped with
a warning and the main model is fitted alone.
This drops the reservation block in the server, which no longer has to
probe the trained context size of the target to guess an upper bound.

* ui : rework the settings registry into ordered raw-data sections
SETTINGS_REGISTRY becomes an ordered SettingsSectionEntry[] array; the
array order is the sidebar display order. Section titles, color mode
options and title radio options are declared inline in their section or
entry. Entries gain showInUi; MCP servers, the system-message toggle and
the title LLM flag become hidden entries of their own section.
Derived values (config defaults, help info, chat sections, numeric field
lists, syncable parameters) are still derived here; they move to their
actual consumers in follow-up commits.
* ui : extract settings localStorage persistence into SettingsService
Stateless load/save of the settings config and user-override keys, plus the
legacy theme key migration. Business logic (default merging, mobile
sendOnEnter default, applying the migrated theme) stays in the store.
* ui : move the settings exit route into ROUTES
SETTINGS_FALLBACK_EXIT_ROUTE is just a route, so it lives with the other
routes as ROUTES.SETTINGS_EXIT.
* ui : derive the syncable parameter list in the parameter sync service
The syncable parameter mapping is only consumed by the sync service, so
derive it there from the registry instead of exporting it from the
constants file.
* ui : restore isPrivate for API key masking
* ui : clean up settings registry and router fetch guard
Drop the per-entry section field (duplicates the parent slug and is
never read) and guard the router model fetch on fields?.length so the
Tools/Import-Export pages with empty fields are excluded again.

* ui: Extract server stream lifecycle from chatStore into ChatStreamManager
Discovery, attach/replay, resume retry and the remote-running snapshot
formed a cohesive cluster inside chatStore. It now lives in
chat-streams.svelte.ts as ChatStreamManager, owned by chatStore, which
keeps the public entry points as delegates so components are
unchanged. chatStore: 2877 -> 2418 lines.
* ui: Extract user interaction gates from agenticStore into AgenticGates
Tool permission requests, turn-limit continue prompts and queued
steering messages are the state the loop waits on between turns. They
had no coupling to session state, so they now live in
agentic-gates.svelte.ts; agenticStore keeps delegates so components
are unchanged. agenticStore: 1196 -> 1073 lines.
* ui: Compose MCP resources under mcpStore.resources
Resource state was a second import scope next to mcpStore. Consumers
now go through mcpStore.resources, so the MCP surface is one store;
mcp-resources.svelte.ts stays a separate file owned by mcpStore.
* ui: Reorganize stores into domain namespaces
* fix: Update stale doc comments
* ui: Consolidate conv running-state into a chat activity ledger
Running-state was split across chatStore.chatLoadingStates (local
pipes), ChatStreamManager.remoteRunningConvs (backend sessions) and
attachingConvs (attach lifecycle), unioned by hand in
getAllLoadingChats and cross-cleaned by setChatLoading calling
streams.clearRemoteRunning - the 'spinner ghosts until tab toggle'
workaround.
chatActivityStore now owns both sets with one transition per event:
markLocal / localEnded (local pipe end also drops the stale remote
hint, no cross-owner call) / applyRemoteSnapshot (diffed). The
sidebar reads chatStore.activity.loadingConvs through the unchanged
getAllLoadingChats entry point.
Consequences:
- isStreamingActive and its five manual writers are gone; isStreaming()
now reports whether the active conversation has a live streaming
pipe, which is what all four consumers (assistant row, stop action,
context gauge, chat screen) actually check
- isLoading/isReasoning become derived from the per-conv maps plus
the active conversation, dropping the manual resync in
syncLoadingStateForChat and clearUIState
- attachingConvs and the last-attach coordination disappear from
ChatStreamManager
- getAllStreamingChats (no consumers) is removed
* ui: Give store collaborators narrow host interfaces
Collaborators took 'host: typeof <store>', i.e. the store's entire
public surface, which is how chatStore's streamChatCompletion,
createAssistantMessage, getApiOptions and setStreamingActive got
widened to public. Replace with per-collaborator interfaces carrying
only the members each one drives:
- ChatStreamHost (chat/streams) - activity, processing, streaming
states, abort controller, loading/streaming setters
- ChatFlowsHost (chat/flows) - streaming core, message creation,
per-conv state setters
- McpHealthHost (mcp/health) - connection registry + reconnection
- ModelPropsHost / ModelStatusHost (models) - model rows, feed
updates; the managers write modalities/status back onto the host's
rows, so those members stay writable
- ConversationsPreferencesHost (conversations) - the active row and
the conversation list
The store classes now declare 'implements <Host>' so the contract is
visible at the class level, and the 'import type { <store> }' back
references in the collaborators disappear entirely - the host
contract is local to each collaborator file, and collaborators can
no longer reach around their slice. Members stay public (structural
typing), but the collaborator side is now compiler-enforced.
* test: Chat Activity store test
* refactor: Cleanup
* chore: Remove legacy architecture docs
* ui: Memoize findMessageIndex for the streaming hot path
Streaming looks up the same message index on every chunk, a linear
scan of activeMessages each time. Cache the last lookup and reuse it
after validating the id still sits at the same position (O(1)); any
structural change to the array fails validation and falls back to a
full scan.
* ui: Throttle per-chunk stream state writes to localStorage
saveStreamState ran JSON.stringify + a synchronous localStorage.setItem
on every decoded chunk of the stream. The read loop now goes through a
new saveStreamStateThrottled (one write per conversation per 500ms,
latest value held pending); the public saveStreamState keeps its
immediate-write contract for stream start and pre-fetch, and also
resets the throttle window.
A pending offset is force-flushed at resume boundaries (resumeStream
reads the offset back from localStorage), on visibilitychange->hidden
and on pagehide, so a reload always finds a usable offset. The resume
offset only needs to be roughly current since the server retransmits
from a line boundary and the client discards its partial line.
Adds unit tests for the throttled/flush/clear interplay.
* ui: Compute context gauge timing stats in one pass
currentRead/Fresh/Cache/Output were separate deriveds, each running a
full reverse scan of activeMessages for the last assistant timings,
and cumulative ran its own forward scan plus an agentic filter - 4-5
O(n) passes per chunk while streaming. Replace with a single
summarizeAssistantTimings() pass (last assistant timings, last
agentic llm totals and the cumulative sums) feeding a shared derived
snapshot. Semantics unchanged, including the live-stats overrides and
the agentic llm-totals branch.
* agentic : clear session state when a conversation is deleted
Every conversation that ran an agentic flow left an AgenticSession in the
store forever; clearSession was never called. conversationsStore now
notifies deletion listeners and agenticStore drops the matching sessions,
avoiding a circular import back into conversationsStore.
* chat : extract ChatService.normalizeMessagesForApi
The DB->API message normalization (convert + drop empty system messages)
was duplicated in sendMessage, preEncode and the agentic flow. Extract it
into one shared method and call it from all three.
* sse : share record splitting and data extraction
splitSseRecords and extractSseDataPayload centralize the record-boundary
splitting and data: line extraction used by parseSseJsonStream and the
models status feed. chat.service keeps its own line-based parser for
resume support.
* api : delegate apiFetchWithParams to apiFetch
apiFetchWithParams duplicated apiFetch's headers/fetch/error handling
body-for-body; it only differs in URL construction. Build the URL and
delegate.
* chat flows : dedupe title, timings and cleanup handling
- conversationsStore.applyTitleFromContent centralizes the title-from-first-
message logic duplicated in 5 places
- ChatProcessingStore.applyStreamTimings centralizes the onTimings handler
shared by the chat and continue flows
- host.cleanupStreaming centralizes the loading/streaming/processing reset
repeated across the continue flow's exit paths
* conversations : centralize conversation update mirroring
rename, pin, mcp override, reasoning effort and cwd all repeated the same
write-DB-then-mirror-into-list-and-active dance. A single
applyConversationUpdate(id, updates) on the host collapses all five and
removes the forgot-to-mirror-one-field bug class. Drops the redundant
array reassignment in setCwd (deep field assignment is reactive).
* mcp : dedupe tool execution, server parsing and tool indexing
- executeTool delegates to executeToolByName (only diff was argument parsing)
- drop the private #parseServerSettings copy; use parseMcpServerSettings
- cache getServers() keyed on the raw config value (hot path)
- indexServerTools() unifies the three identical toolsIndex rebuild loops

/tools API). Fix stale architectural patterns for per-conversation state
and modality validation.
* chore : add ESLint rule for blank lines between accessors
Enforce a blank line between consecutive class accessors. The core
padding-line-between-statements rule does not cover class members, so a
local rule is needed.
* refactor : reorder store members and unify naming
Order store class members as public fields, private fields, constructor,
getters, public methods, then private methods. Normalize private naming
to the `private` keyword (drop `#` and the `_` prefix where there is no
matching public getter). Rename conversationsStore.init() to
initialize() to match the other stores.
* refactor : prefix lookup methods with get in agentic and chat stores
Unify bare-name lookup methods with the get* prefix used across the
other stores (mcp, models, tools, settings). Renames currentTurn,
totalToolCalls, lastError, streamingToolCall, executingToolCallId,
pendingPermissionRequest, pendingContinueRequest,
pendingSteeringMessageContent, pendingSteeringMessageExtras in the
agentic store and pendingMessageContent, pendingMessageExtras in the
chat store. Updates the two consuming components and a doc comment.
* refactor: Clean up comments in stores' and services' code
* chore : add ESLint rule for class member ordering
Enforce structural order (public fields -> private fields -> constructor ->
getters -> setters -> public methods -> private methods) with alphabetical
sorting within each group via perfectionist/sort-classes. Dependency
detection keeps Svelte $derived fields in a valid dependency order instead
of alphabetizing them, since Svelte rejects forward references.
