Problem

With multiple connected machines hosting the same repository, the sidebar's project filter combines their chats and cannot show just one machine's chats. Users should be able to narrow that existing view to a machine, optionally together with a project selection, without changing the default all-machine view.

Change

Extend the existing sidebar filter with a Machines section alongside Projects. A machine and one or more projects can be selected together; each section has its own reset.

The machine selection is saved locally and applies to thread shelves, drafts, title/message search, older settled threads, and project folders. Opening a thread outside the current scope follows the existing route-reveal behavior and clears the scope. Web and desktop share this sidebar; mobile already exposes an environment filter.

Scope and approval

This is a focused option for the established sidebar filtering capability, using the existing environment catalog and project visibility pipeline. It controls which existing machines' chats appear in the sidebar; all-machine behavior remains the default. The persistence, search, and project-folder changes keep those paths consistent with the selected scope.

This is submitted under the focused configuration option guidance, not as a claim of prior maintainer approval. Eligibility and product direction remain for maintainers to decide.

Verification

• After rebasing onto main at ade473018d32003658b7d38693e083ee2e314bd8, vp run check:changed upstream/main --concurrency 2 completed successfully on head 64b56be5833d9630143b4d7325db104cc89cb03d: formatting, lint, both Knip checks, affected-package typechecks, 151 tests, and focused React Compiler validation passed.
• Two isolated dev servers with a shared repository and a project present on only one server: verified machine selection, combined project scope, no-match empty results, scoped search, independent resets, keyboard selection, and persistence after reloading a thread on the selected machine. Machine labels in the captures below are sample fixture labels.
• Added scope-intersection cases covering shared project IDs across machines, incompatible filters, an empty machine, and all-machine scope; extended the existing persistence test.
• Additional real-environment verification covers two environments on one Linux VM, scoped message search, route reveal, project-folder thread creation, settling/unsettling, and independent resets. That comment also records the subsequent sidebar merge resolution and selected-machine Copy path fix.

Not verified: Electron shell behavior, native iOS/Android UI, platform-specific macOS/Windows UI behavior, relay/tunnel access, connectivity between separate physical machines, and older-thread pagination beyond the small manual dataset. The two-environment checks do not establish cross-host connectivity, and no performance claim is made. The manual UI evidence predates the latest rebase; it was not rerun for that rebase.

Approvability

Verdict: Approved at a103ed4

Macroscope's review found this PR approvable — Adds an optional, persisted machine filter for sidebar threads and searches, with project-folder thread creation following the selected machine. Existing all-machine behavior remains the default, and the change introduces no obvious material risk requiring human judgment.

Walkthrough

The sidebar adds machine and environment scopes alongside project scopes. It persists the selected environment and applies that scope with project filters to sidebar content, thread search, and folder actions.

Changes: Environment-scoped sidebar filters

Layer / File(s)	Summary
Persist environment scope apps/web/src/uiStateStore.ts, apps/web/src/uiStateStore.test.ts	UI state now includes a nullable sidebar environment scope identifier. Parsing normalizes missing or invalid values to null, persistence saves the value, and tests cover defaults and restoration.
Derive environment-scoped sidebar content apps/web/src/components/Sidebar.logic.ts, apps/web/src/components/Sidebar.logic.test.ts, apps/web/src/components/Sidebar.tsx	Project keys are constrained to the selected environment when one is selected. Sidebar references, connected environments, folders, and thread loading use the selected environment. Route reveal clears the environment scope. Folder thread creation and path copying use a matching project when available.
Select and render machine scopes apps/web/src/components/Sidebar.tsx	The filter menu adds machine choices and separate machine and project groups. Selection labels, icons, and search cover both scope types. Non-empty search excludes the “All” and “All machines” choices.

Full details: Title check

Explanation

The title "feat(web): filter sidebar threads by machine" matches the main change. The PR adds a Machines section to the sidebar filter, so threads can be scoped to one machine. The title is short, uses a conventional commit prefix, and names the primary change. The title does not mention the project filter or the persisted environment scope, which are secondary parts of the same change.

Full details: Description check

Explanation

The description follows the repository template closely. It has Problem, Change, Scope and approval, and Verification sections. The Problem section explains the issue and the expected behavior. The Change section explains the Machines filter and its persistence and scope rules. The Scope and approval section cites the focused configuration option guidance and states that the PR is not a claim of prior maintainer approval. The Verification section lists the checks run, the observed results, and what was not verified. It includes before and after screenshots for the UI change. The description does not include a reproduction-steps section for the problem, which the template suggests where relevant. It also does not name the model and harness that did the work, which the template asks for when an agent was used. These gaps are minor. The verification text relies on an external comment for the real-environment checks, and the manual UI evidence predates the latest rebase, which the author discloses.

Merged current main (fd6b9d2bd1)

The PR conflicted with main in Sidebar.tsx. Merged main with a merge commit, no rebase. The filter menu rows now use main's new ProjectRowActions for pin and settings, and keep this PR's Machines/Projects group headers and machine icons. "All" and machine rows get the same spacer main added so every row has the same height.

A CodeRabbit finding was real: with a machine selected, a project folder's "Copy path" copied the other machine's root. 748437fea4 makes it use the selected machine's member, like "New thread" already did.

vp run check:changed passes on a testbox: format, lint, knip, typecheck, 151 tests.

Verified in a real dev environment

verified unchanged head a103ed460b0924403135a1dad94f94a6b5cfcfa8 on a linux boat vm using the repository's playwright dependency and /usr/bin/google-chrome.

reproduced the missing behavior on github/main (8b44f42b14): the filter offered projects only. stopped that dev server before starting the exact pr head on web port 8693 and server port 16733. the second environment was the vm's existing installed server on port 3773, paired through settings. only one dev server ran at a time.

created the project and threads through the app against a real git checkout. real codex gpt-6.1-sol turns returned alpha on the dev environment and beta on the paired environment. the pr server completed a further gamma turn. no mocks, fixtures, replay provider, or demo data were used for these scenarios. both environment labels are the vm's actual hostname, so the captures show the same label twice.

• selecting each machine showed its threads and excluded the other machine's threads and drafts.
• machine and project scope worked together. each "all" reset preserved the other section's selection.
• message search found alpha locally; scoped search excluded beta, and all-machine search found beta.
• reloading a thread preserved its machine filter. opening an alpha thread while scoped to beta cleared the scope and revealed alpha.
• with project folders enabled, creating a thread from the grouped repository used the selected dev environment (6256c761-c64e-4732-b890-21a09702c083) and completed a real delta turn. settling it produced local settled count 1 and other-machine count 0; un-settle restored it.

runtime transcript:

local scope excludes beta: PASS
combined machine + project: PASS
local message/title search excludes beta: PASS
all machines preserves project: PASS
all-machine search finds beta: PASS
remote scope excludes local alpha: PASS
all projects preserves machine: PASS
reload persists selected machine: PASS
opening outside-scope alpha clears machine filter: PASS

blacksmith: vp test run apps/web/src/components/Sidebar.logic.test.ts apps/web/src/uiStateStore.test.ts passed 109 tests across both files. the pr reports 31 successful checks. no source changes or pushes were needed.

Not verified

electron shell, native ios/android, macos/windows, other providers, relay/tunnel access, and older-thread pagination beyond this small real dataset were not exercised. the two environments ran on this vm; this does not prove connectivity between separate physical machines. no performance claim is made.
