What

The sources panel's ticks now belong to the chat they are made in:

  • Opening a thread puts its stored source_scope on screen, every source for a thread that never stored any.
  • A tick made in an open thread between turns goes to PUT /chat/threads/{id}/source-scope at once, one store after another per thread, so the thread shows it again when opened next. A store that fails is said in a toast, translated into every language; the next turn sends the ticks anyway. A tick made while the thread's entry is still on its way stays and is stored once the entry arrives.
  • A new chat starts from every source and keeps its ticks in localStorage until it is sent, so they survive a reload. The send opens the thread with them (POST .../chat/threads takes source_scope; left out when every source is ticked) and spends the draft right after, so the ticks outlive a first message that fails.

marksOf() in scope-state.ts is the inverse of scopeOf(): the ticks a stored scope describes, with a listed folder or source carrying its own mark and all deciding the rest, so the panel takes in exactly the sources the server resolves, a file added later to a listed folder included. The scope hook counts the user's own ticks apart from a scope it was handed, so the thread hook can tell a tick to store from the scope it just loaded.

Why

docs/architecture/chat.md listed this under Known gaps: the ticks belonged to the workspace for the session, so opening a thread kept whatever was ticked before, not the scope the thread had stored, and a new chat lost its ticks on a reload. The API already stored a scope on every turn and offered the read and store routes; nothing on the client used them. The gap line is replaced by the behaviour.

How to test

cd surfsense_local/frontend
pnpm test -- src/features/sources/tree/scope-state.test.ts src/features/dashboard/dashboard-page.test.tsx
pnpm typecheck && pnpm lint
  • scope-state.test.ts, "ticks from a stored scope": a stored folder shows ticked with a file added to it later; excluded and added-back sources show as such; a listed folder under an excluded one is left out, as the server leaves it; the scope the ticks send round-trips.
  • dashboard-page.test.tsx, six scenarios over two chats, one with a stored scope: "opens a chat with the sources it stored" (each chat shows its own ticks), "stores a tick made in an open chat on it, and shows it again on return" (the tick goes to PUT /chat/threads/10/source-scope with the scope the ticks describe), "keeps a tick made while the chat's entry was still on its way, and stores it", "says so when a tick could not be stored on the chat" (the store answers 503, the toast shows, the tick stays), "opens a new chat's thread with its ticks, which outlive a first message that fails" (the thread is created with the scope, the draft is spent, the message answers 503, reopening the thread shows the ticks), and "starts a new chat from every source and keeps what it unticks across a remount".
  • The dashboard scenarios fail without the hook wired in (useThreadScope removed from dashboard-page.tsx): the ticks stay those of the session.

In the app: tick a folder in a chat, open another chat, come back: the folder is still the only one ticked. Start a new chat, untick something, reload: it is still unticked.

Summary by CodeRabbit

  • New Features
    • Chat source selections now persist per conversation and reload when reopening a thread.
    • New-chat source selections are retained across page reloads until the chat is created.
    • Source changes made during active replies or thread creation are preserved and saved afterward.
    • Added notices for pending source updates and errors when selections cannot be saved.
  • Translations
    • Added localized messages for source-selection saving in supported languages.
  • Bug Fixes
    • Improved handling of nested folders, exclusions, and newly added sources when restoring selections.

marksOf() is the inverse of scopeOf(): the ticks a stored source scope
describes, a listed folder or source carrying its own mark and all deciding
the rest, so they take in exactly the sources the server resolves, a file
added later to a listed folder included. The scope hook can put such a scope
on screen, and counts the user's own ticks apart from it, so a chat can tell
its ticks from the ones it was opened with.
The sources panel's ticks belonged to the session: opening a thread kept
whatever was ticked before, not the scope the thread had stored, and a new
chat lost its ticks on a reload.

Opening a thread now puts its stored source_scope on screen, every source
for one that never stored any. A tick made in an open thread between turns
is stored on it through PUT /chat/threads/{id}/source-scope at once, so the
thread shows it again when opened next; a store that fails costs nothing,
since the next turn sends the ticks anyway. A new chat starts from every
source and keeps its ticks in localStorage until it is sent, which stores
them on the thread it makes and spends the draft. A thread the client made
itself keeps the ticks that started it until the list is read again.

Walkthrough

Chat source selections now persist per thread. New-chat selections are retained in workspace drafts, applied when a thread is created, and cleared after creation remains current. The dashboard restores stored selections and saves edits, with writes deferred during active replies.

Changes: Chat source scope

Layer / File(s) Summary
Reconstruct and track source selections
surfsense_local/frontend/src/features/sources/tree/scope-state.ts, surfsense_local/frontend/src/features/sources/tree/scope-state.test.ts, surfsense_local/frontend/src/features/sources/tree/use-source-scope.ts, surfsense_local/frontend/src/features/sources/use-sources.ts
Stored scopes can be converted to source-tree marks. The source-scope hook exposes setScope and tracks user edits separately from restored marks. Tests cover folder and document inclusion, exclusions, and nested-folder precedence.
Load and persist chat scopes
surfsense_local/frontend/src/features/chat/api.ts, surfsense_local/frontend/src/features/chat/use-thread-scope.ts, surfsense_local/frontend/src/features/chat/use-chat-runtime.ts, surfsense_local/frontend/src/features/chat/use-thread-scope.test.tsx
The chat API reads and stores thread scopes and accepts a scope when creating a thread. The hook validates workspace drafts, restores thread scopes, serializes saves, and defers writes during replies. New-thread creation sends the scope and clears the draft when the request remains current.
Connect and verify chat scope lifecycle
surfsense_local/frontend/src/features/dashboard/dashboard-page.tsx, surfsense_local/frontend/src/features/dashboard/dashboard-page.test.tsx, surfsense_local/frontend/translations/*, docs/architecture/chat.md
The dashboard connects source state to the thread-scope hook. Tests cover restoration, saves, deferred writes, failures, and draft persistence. Translations add save notices and errors, and the architecture documentation describes the scope lifecycle.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Loading
Merge Risk: Low · previous review 12c9b

Leaving a chat during a reply can lose a source selection. The impact is bounded, but the selection should survive navigation and be saved after the reply ends.

Security architecture risk: Moderate · up to 12c9b

A delayed source-selection save can overwrite the selection submitted with a message. During a reply, this may allow searches of documents the user excluded for that turn. The demonstrated exposure remains within the chat’s workspace.

Retained concerns

  • Medium · security · inferred: Pending source-scope saves are not ordered with turn initiation. An earlier broader selection can be queued before the user submits a narrower selection, then commit after the message stores its scope. Subsequent agent-tool calls read that broader thread scope rather than immutable turn authority, potentially returning excluded document passages despite narrower turn metadata and mirrored files.
Security review details

Security Blast Radius

  • inferred — The demonstrated race affects source-selection authority for an individual thread. A stale all-sources selection could expose ready passages across that thread’s workspace to later tool searches. Cross-workspace access, additional credentials, and unauthenticated remote exploitation are not established by this path.

Security Findings and Attack Paths

  • inferred — A broader edit waits behind an earlier save; the user then submits a narrower selection before that queue drains. If the broader PUT commits after turn initialization, a subsequent model-requested search uses its expanded identifiers and can return passages excluded from the submitted selection. User interaction and request timing are required; an actual disclosure was not reproduced.

Trust Boundaries and Controls

  • observed — The inspected agent-tool route retains launch-key, web-page-caller, and protocol checks. Its scope lookup also verifies that the addressed thread belongs to the workspace and uses an agent. These checks do not make the selected scope immutable during the turn.

Resilience and Maintainability Implications

  • observed — Per-thread promise chaining prevents PUT-to-PUT reordering within one hook instance. Edits observed during an active reply are held until it ends. Neither control includes already queued PUTs in the message-send ordering boundary.

Hardening Proposals

  • proposed — Separate persisted next-turn preferences from immutable active-turn authority, and bind tool requests to that turn snapshot. Coordinate preference writes and turn initiation with server-enforced ordering or revisions so stale saves cannot silently replace newer selections.

… server does

The server takes every listed folder's subtree before it removes the excluded
folders', so a folder listed under an excluded one is out of the scope. The
ticks a stored scope describes now give such a folder no mark, which takes
the index to walk its parents; scopeOf() never writes that combination, but
a scope sent by a plugin or an older client can.
… fails

A tick made while the thread's entry was still on its way was dropped once
the entry arrived and its stored scope replaced it. Such a tick is the
user's for that thread: it stays, and the thread gets it once the entry is
there.

Each thread's stores now run one after another, so an older request cannot
land after a newer one and leave the thread with ticks the user has changed.
A store that fails is said in a toast, in the interface language: the next
message sends the ticks anyway, but until then the thread would open with
its earlier ticks after a reload.

…aft only then

The draft was spent as soon as the thread a new chat made became the open
one, while its ticks were only sent with the first message. A message that
never reached the backend left the thread with no scope and the ticks gone.

The thread is now opened with the ticks, through the source_scope the API
takes at creation, left out when every source is ticked, and the draft is
spent right after that succeeds: the ticks outlive a first message that
fails, and the thread shows them when opened next.

A new chat started while the previous one's thread was still opening wrote
its ticks under the same draft, which the opening then spent. The draft is
now read when the opening starts and spent only if it is unchanged once the
thread exists, after the request version check.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Reconcile the scope cache with the PUT response.

storeThreadScope returns the server-pruned source_scope, but the success handler discards it. If the source list still contains a source that the backend has removed, the stale tick can remain displayed and be sent again on the next edit. A thread-list refresh can repair the cache, but the active hook does not apply that refreshed scope while the thread remains shown.

Thanks @samuelmbabhazi. Much of this is right:

  • The folder rule. We resolved 3,000 random trees and scopes with the server's resolve_scope and the client's marksOf. Every ordinary case agrees, including 634 with a listed folder under an excluded one; the old marksOf got 203 of them wrong.
  • The four new behaviours each have a test that fails without them: keeping an early tick, the failure toast, opening the thread with the draft's ticks, and spending the draft only after the create.
  • The catalogs check out.

Two things before it can merge, both about when ticks are stored.

1. Ticks are now stored mid-turn

The effect at use-thread-scope.ts:184-193 stores on every tick, including while the open thread's reply runs. The agent's tools read the stored scope on every call (agent/tool_endpoint/turn_scope.py:78-91). So in an Agentic thread, unticking a source while a reply runs switches that turn's tools at once, while its scope note and sources/ folder keep the old ticks.

agent.md:278 says "the app sends ticks with each message, never mid-turn". Your own chat.md:24 describes the PUT as "store ticks made between turns". Hold a thread's stores while its reply runs; the next turn sends the ticks anyway.

2. A tick made while a new chat is being created goes to the next chat

This came with 2ef12ae. Here is what a user does:

  • in a new chat, untick Research and send;
  • while the create is pending, untick Guide.txt (that can take seconds in Agentic, while the session opens).

The new chat then shows Guide.txt ticked again and stores nothing for it, and the next New chat starts with both unticked. Why:

  • during creating the view has no thread id yet (use-thread-scope.ts:110), so the tick is written to the draft and marked seen (:184-191);
  • the draft no longer matches the snapshot taken at send, so clearDraftScope keeps it (use-chat-runtime.ts:646, :658);
  • when the thread opens, its creation-time scope replaces the screen (use-thread-scope.ts:177-178).

A genuinely newer chat already bumps the request version and returns at use-chat-runtime.ts:653, before the clear. So the snapshot check only ever sees the same chat's own tick. Leave a tick made while creating unseen, so the early-tick branch (use-thread-scope.ts:172-176) stores it on the thread once it opens. Then spend the draft without the snapshot check.

Not blocking: no test covers the stores running in order (use-thread-scope.ts:130-132) or the snapshot at the call site (use-chat-runtime.ts:658). Reverting either still passes every test.

Push the fixes to this branch and it will be reviewed again.

… made while its thread opens

Two cases stored ticks at the wrong moment.

A tick made while the open thread's reply ran was stored at once, and the
agent's tools read the stored scope on every call, so unticking a source
mid-turn switched that turn's tools while its scope note and folder kept
the ticks it started with. The hook now holds a thread's stores while a
run is live for it (it follows the run store) and stores the held ticks
once the run ends; opening a thread that holds ticks shows them.

A tick made while a new chat's thread was being opened was written to the
draft and marked seen; the draft then differed from the snapshot taken at
send, survived, and the thread's creation-time scope replaced the screen,
so the tick was lost and surfaced in the next new chat. A tick made while
the view is creating is now left unseen, so the early-tick branch stores
it on the thread once it opens, and the draft is spent without a snapshot
check: a genuinely newer chat already ends the opening before the clear.

Two dashboard scenarios cover them, each red without its fix: a tick during
a streamed reply is not stored until the reply ends; a tick during a held
thread creation lands on that thread and the next new chat starts over.

- Around line 184-202: Move the held-scope queue out of the useThreadScope hook
into a module-level lifecycle owner so it survives DashboardPage unmounts. Use
onRunEnded from the run store to flush each queued scope via its store callback
only after the reply ends, while preserving the existing idle cleanup and

effect.

samuelmbabhazi force-pushed the fix/thread-source-scope-restore branch from 12c9b8e to 00e025c Compare October 20, 2026 06:34
The ticks held while a thread's reply runs, and the order of a thread's
stores, lived in the hook, so leaving the dashboard before the reply
ended dropped a held tick. They now live at module level, like the run
itself, and the run store's ended event flushes the held tick through
the usual serialized store. Mounted pages register a cache writer so the
threads cache stays in step while the page is there.

Both changed, in 00e025c:

  1. No store mid-turn. The hook follows the run store: while a run is live for a thread, its ticks are held and stored once the run ends; opening a thread that holds ticks shows them. The next turn sends the ticks anyway. Covered by "holds a tick made while the chat's reply runs, and stores it once the reply ends", which fails with a store on every tick.
  2. A tick during creating goes to that thread. It is left unseen until the thread opens, so the early-tick branch stores it there, and clearDraftScope spends the draft without a snapshot. Covered by "stores a tick made while a new chat's thread was opening on that thread, not on the next chat", which fails without the guard.

The two gaps you listed: the ordered stores now have a unit test (use-thread-scope.test.tsx, a second store waits for the first to settle), and the snapshot at the call site is gone with the snapshot. Full suite 1026/1026, translations and docs checks clean; chat.md says when ticks are stored.

Merged dev into the branch, the PR had fallen 868 commits behind. One conflict, two imports in use-chat-runtime.ts, nothing else changed in the 21 files. Frontend suite, typecheck, lint, translations and docs checks pass. Ready for another look when you have time.

Reviewed this again. Both asks from last time are done, each with a test that fails without it: a tick made while the reply runs is held and stored once the run ends, and a tick made while a new chat's thread is opening goes to that thread. Your 9 November merge changed none of the PR's own lines.

Since then dev merged #2431 (10 November), which clashes with this PR's design, not just its text, and one more path in the opening race needs closing. We want both: each chat keeps its own ticks, as this PR does, built on #2431's remembered ticks.

1. Build the chat's ticks on #2431's remembered ticks

#2431 starts a workspace with nothing ticked and keeps its ticks across launches (remembered-ticks.ts; docs/architecture/documents.md:70, www/content/docs/v2/sources.mdx:127). This PR starts a new chat from every source (use-thread-scope.ts:190) and keeps its own draft (surfsense:draft-scope:<workspace>:v1). Merged as they are, dev's use-source-scope.ts saves every change to the remembered ticks (its useEffect at :43-44), so every thread you open would overwrite them.

What to change

  • A new chat starts from the workspace's remembered ticks (readRememberedTicks), not from every source, and ticks made in a new chat are remembered as dev does now. Drop the separate surfsense:draft-scope draft: the remembered ticks already survive a reload, and a send no longer spends them.
  • Opening a thread shows its stored source_scope, and ticks made in a thread go to that thread only, through your PUT. Neither ever writes the workspace's remembered ticks.
  • Resolve use-source-scope.ts as dev's block plus your edits counter, with the thread path kept out of rememberTicks.
  • Update the tests that expect a new chat to start from every source (dashboard-page.test.tsx:2316, :2361, :2371) and dev's createThread body assertions, which gain source_scope, and keep dev's "sends a ticked folder as the turn's source scope" (:1843 on dev) passing.
  • Docs: in chat.md, take your deletion of the Known gaps line (:302 on dev) and rewrite :248's last sentence for the new chat; update documents.md:70 and sources.mdx:127 to say each chat keeps its own ticks.

2. A tick made while a new chat is opening can land on another chat

The fix for last time's second ask leaves a tick made during creating unseen until a thread opens (use-thread-scope.ts:218), and the thread that opens next gets it (:196-201). But selectThread (use-chat-runtime.ts:320-333) has no guard for creating, and an abandoned create returns at the version check without opening its thread. So: start a new chat, untick a source while it opens, then open an existing chat. That chat gets the new chat's ticks stored on it with PUT, and its own ticks never reach the screen.

What to change

Store a tick made during creating only on the thread that create opens. If another chat opens first, keep the tick with the new chat's ticks and show the opened chat's own scope. Add a dashboard test: hold the create, untick a source, open another chat, release the create. Expect no PUT to that chat's source-scope, and its own ticks on screen.

Push the fixes to this branch and it will be reviewed again.
