fix(server): project updates on folded settings reach new threads - #35452
Rework of both review items. (1) Ordering/idempotency: the projectSettingsOverrides write now happens inside ProjectService.commit's planAndCommit, only when eventSink.commitProjectCommand reports committed:true (a fresh commit, not a replayed receipt), and under the existing project lock. A retried command therefore never rewrites settings, and fresh commands write settings in commit order. This covers create and update. (2) Lost concurrent edits: ServerSettingsService.updateSettings now also accepts a function from current settings to a patch, resolved inside the settings write semaphore (real service and test layer, through an exported resolveServerSettingsPatch helper). ProjectService uses it to merge only the fields the command carries into the project's current override entry: scripts become defaultProjectScripts; defaultModelSelection, defaultThreadEnvMode and autoPull→defaultAutoPull on update; null deletes the key. Another client's concurrent edit to an unrelated key such as defaultAutoPull is no longer overwritten by a stale entry. Narrowing: create now writes only scripts, not defaultModelSelection (the create command never carried a model), and the 'update-settings' ProjectOperationError literal added in round one is gone; settings failures surface as dispatch-project-command errors. Three test mocks of ServerSettingsService (DeviceService, ThreadSettlementService, ProviderRegistry) were updated for the wider parameter type. Trade-off: if the settings write fails after the command commits, retrying the same command id will not write it again; a new command id will. No new regex or parser. There is no test for item 2: the interleaving could not be forced without a test-only hook.
Commit f03db4f (origin/main). Ran the worktree dev server with T3CODE_DEV_SEED=0. After the first start auto-registered a project, restarted it, and the startup fold set projectSettingsFolded: true in the worktree's settings.json. Using a scratch driver that signs in as an MCP client the way t3 thread does (issueMcpClientSession + /mcp): (1) t3_project_create {title:'repro', workspaceRoot:}; (2) t3_project_update {scripts:[{id:'setup',name:'Setup',command:'echo ran > SETUP_RAN.txt',icon:'configure',runOnWorktreeCreate:true}], defaultThreadEnvMode:'worktree'} returned isError:false and echoed both values, t3_project_read returned them, and settings.json had no projectSettingsOverrides entry; (3) t3_thread_launch {modelSelection:{instanceId:'devReplay',model:'showcase'}, workspaceStrategy:{type:'worktree',baseRef:'main',branch:'repro-setup'}} created the worktree and the turn completed, but the worktree held only README.md: the setup action never ran. Control: wrote the same action to projectSettingsOverrides..defaultProjectScripts and launched again with branch control-setup; that worktree contained SETUP_RAN.txt ('ran'). A unit test on branch factory/repro-14991 also fails on main for both scripts and defaultThreadEnvMode.
Evidence
On fresh folded installations, create a project through MCP, update its setup action and defaultThreadEnvMode, read it back, then launch a replay turn in a worktree from main and wait for completion. Both tools report success. Base ignores the settings and creates no marker; head displays the settings and creates SETUP_RAN.txt containing ran.
Environment: Linux Chromium web client, 1280×800 viewport, light theme, isolated fresh databases with seeding disabled. Matching crops exclude private metadata.

Tests
apps/server: vp test run src/project/ProjectService.test.ts -> 16/16 pass; with the previous head's ProjectService.ts swapped in, the new retry assertion fails ('worktree' vs 'local'). vp test run src/serverSettings.test.ts src/project src/mcp/toolkits/project -> 277 passed, 2 failed in RepositoryIdentityResolver.test.ts, which failed the same way on base in round one (this VM's git config rewrites SSH remotes to HTTPS). apps/server vp run typecheck -> no errors. vp run check:changed -> format, lint, knip, graphql, typecheck (3 packages), tests (7 files) all pass.
Not in this change
t3_project_read/t3_project_list (ProjectService.toProject) still return the legacy row's scripts/defaultThreadEnvMode/defaultModelSelection, so values set from the Settings UI on a folded install are not reflected there; resolving effective values in the read tools is a separate change.
Read-modify-write of the per-project override entry is not atomic against a concurrent settings write (same pattern the web clients use); a transactional patch helper in ServerSettingsService would close it.
RepositoryIdentityResolver.test.ts fails two cases on this VM because of a global git URL rewrite; unrelated to this fix.
t3_project_read/t3_project_list (ProjectService.toProject) still return the legacy row's scripts/defaultThreadEnvMode/defaultModelSelection rather than the effective resolved values.
If the settings write fails after a project command commits, a retry of that command id does not re-attempt the write; recording the pending settings write in the outbox would make it durable.

Failing reproduction for #14991: on a folded install, scripts and
defaultThreadEnvMode saved through ProjectService.update never reach the
resolvers launch and the UI read.
AI-assisted; verified with the tests and tools listed above.
ProjectService.update and create wrote scripts, default thread mode,
default model and auto-pull only to the legacy project record, which
launch, the Actions menu and Settings stop reading once project settings
are folded. They now also write the matching projectSettingsOverrides
entry, so agent writes through t3_project_update take effect.

…t edits
Write the settings overrides only when a project command first commits,
under the project lock, so a retried command cannot reapply a superseded
value. Merge the per-project entry inside the settings write lock by letting
updateSettings take a patch computed from current settings, so concurrent
edits to other override keys are kept.

The change adds function-based server settings updates and writes project command fields to settings overrides on the first accepted, non-delete command. Tests cover update resolution and project setting behavior, including a retried command.
Changes: Server settings and project overrides
Layer / File(s)
Summary
Resolve server settings updates apps/server/src/serverSettings.ts, apps/server/src/device/DeviceService.test.ts, apps/server/src/orchestration-v2/ThreadSettlementService.test.ts, apps/server/src/provider/ProviderRegistry.test.ts
updateSettings accepts a patch or a function of current settings. Test and persisted settings services resolve functional updates before applying them. Related test helpers resolve updates against current settings.
The first accepted non-delete project command writes defined scripts and metadata fields to project settings overrides. Tests cover settings resolution and confirm that retrying an earlier command does not replace a later thread environment mode.
Project updates now propagate to settings overrides on folded-settings installs, which addresses the linked issue. If the settings write fails after the command commits, retrying the same command will not repair it. The project can then keep stale script or default settings while the call reports success. Resolve this, or explicitly accept the limitation, before merging.

Full details: Title check
Explanation
The title names the fix and the affected flow: project updates on folded settings now reach new threads. The changeset adds projectSettingsOverrides writes in ProjectService, a settings update resolver, and test updates, which together make project script and mode changes apply to new worktree threads. The title is specific and follows the conventional commit form the template asks for. It omits the concurrency-safety part of the change, which is acceptable because the title need not cover every detail.
Full details: Linked Issues check
Explanation
Linked issue #14991 is the only active direct target. Its requirement: a setup action supplied through t3_project_update must run when a thread launches with a worktree strategy, or the tool must report that it cannot apply the change. At head e4d37c9, ProjectService.commit calls writeProjectSettingsOverrides after eventSink.commitProjectCommand reports committed:true for non-delete commands, under the project lock. The helper writes scripts to projectSettingsOverrides[projectId].defaultProjectScripts. For project.meta.update it also writes defaultModelSelection, defaultThreadEnvMode, and defaultAutoPull. The override entry is merged through ServerSettingsService.updateSettings with a function, so it resolves against current settings under the settings write semaphore. Since resolveProjectScripts and resolveProjectOverrides read these override keys when the install is folded, the scripts and defaults written by t3_project_update now reach new worktrees. The PR's main-branch reproduction shows the bug: the setup action did not run, and the same action written to the override entry did run. The PR adds ProjectService.test.ts coverage for folded-settings resolution of scripts and defaultThreadEnvMode, and the author reports 16/16 passing. Gaps that remain, all disclosed by the PR: (a) t3_project_read and t3_project_list still return legacy row values, so they do not show the effective settings; the issue's expected behavior does not name this read path, so it is not counted as a failure. (b) A settings write that fails after a command commits is not retried for the same command id. The autoPull mapping is implemented but has no runtime check; the issue does not require one. No concurrent-write interleaving test exists; the PR states the reason.
Full details: Out of Scope Changes check
Explanation
The changes stay within the scope of #14991. ServerSettings.ts adds ServerSettingsUpdate and resolveServerSettingsPatch, and updateSettings accepts a function. This API change supports the lost-update fix in ProjectService. The updates to the DeviceService, ThreadSettlementService, and ProviderRegistry test mocks only adapt those mocks to the wider parameter type. The ProjectService.test.ts changes add coverage for the reported behavior. The create path now writes only scripts, which matches the create command. The PR does not change unrelated modules in the reviewed summary. The read-tool gap is documented as deferred and is not an unrelated change. I did not inspect the full diff; the assessment relies on the PR summary and one read of ProjectService.ts at head.
Full details: Description check
Explanation
The description follows the repository template. It has a clear Problem, a Change section that explains the ordering and concurrency fix, a Scope section that links issue #14991, and a detailed Verification section with commands, results, and before/after evidence. It also lists what was not exercised and the known trade-offs. The Scope section does not argue for the bug-fix scope in detail, but the linked issue shows the bug. Minor issues: the 'Not in this change' list repeats two items, and the template's closing agent-model line is missing; the AI-assisted note is present but does not name the model or harness.

Add a regression test for lock-scoped update resolution.
The project test checks sequential updates. It does not detect resolution against a stale settings snapshot. Add a deterministic settings-service test that queues a functional update behind another write. Assert that the functional update sees the preceding write and preserves its unrelated override keys. Use Deferred gates, not sleeps.
As per coding guidelines, “Test behavior that can break, such as ... race fixes,” and “Backend behavior changes ship with focused tests for that behavior.”

Mark writeProjectSettingsOverrides with an explicit span choice.
This helper performs a settings write but is a plain arrow. It has no Effect.fn span and no explanation of why it is untraced. It runs inside ProjectService.commit. If the enclosing span covers it, wrap the helper with Effect.fnUntraced and add a short comment beside it that names that span and the project lock. If a separate span is wanted for the settings write, use Effect.fn("ProjectService.writeProjectSettingsOverrides") instead. Either choice follows the default named-span rule for I/O in docs/internals/effect-services.md.

Preserve failed settings work across command retries.
If updateSettings fails after the command commits, the accepted receipt remains stored but the settings override remains unchanged. When the same command ID returns committed: false, this guard skips the failed write. The retry can therefore report success while new threads still use the old settings.
Persist recoverable settings work with the command. Do not report replay success until that work completes. Preserve ordering so recovery of an older command cannot overwrite a newer override.

Squashed port of upstream PR pingdotgg#35452 by juliusmarminge
(open, unmerged), the maintainer rework of the closedpingdotgg#21224, fixing
upstream issue pingdotgg#14991. Once project settings were folded into
settings.json, t3_project_create and t3_project_update saved scripts,
model, thread mode and auto-pull on the project record, which new
threads no longer read. Fresh project commands now merge those fields
into projectSettingsOverrides under the project lock.
Replaces the fork's pull of pingdotgg#21224. Unlike that port, project reads still
return the legacy row's values, and a settings write that fails after
the command commits is not retried for the same command id. Applied
cleanly; nothing diverges from the PR head.
