Project overrides were scattered across the Project aggregate (defaultModelSelection, defaultThreadEnvMode), three ad hoc Record<ProjectId, …> fields in ServerSettings (projectAgentBrowserAccessOverrides, projectAutoPullOverrides, projectScriptOverrides) and a client-settings record. Every other server setting was environment-only, so a real settings hierarchy could not be built on top of them.

This adds one generic projectSettingsOverrides: Record<ProjectId, Partial<scopable keys>> to ServerSettings, with PROJECT_SCOPED_SERVER_SETTING_KEYS as the single list of what a project may override (model, workspace mode, start-from-origin, auto-pull, scripts, browser/device agent access, text-generation and writer models, writing style, default pull request merge method, auto-settle, restart continuation, legacy streaming). resolveProjectSettings(settings, projectId, project?) in packages/shared returns the effective settings plus the source of each key (honouring the project aggregate's own model/workspace fields only until the fold has run, so a reset in the record cannot be undone by a stale aggregate), and every server consumer that acts on a thread or checkout reads through it: agent access gates, thread settlement, title and branch generation, stacked git actions, restart continuation, legacy token streaming, auto-pull and setup scripts.

Legacy fields are folded into the record once on settings load (projectSettingsFolded guards the fold) and the three legacy maps stay populated as derived views for one release so older clients keep working; patches that still use them are translated. Patches replace a project's entry wholesale and null removes it. pullRequestMergeMethod is new on the server (nullable; null keeps using the method last chosen on the device) so the merge method can sit in the same hierarchy instead of a client-only per-project map. A projectSettingsOverrides capability flag lets newer clients hide override controls for older servers.

Base of the settings hierarchy stack; #10636 and #10639 build on it.

Verification: focused tests for the resolver (including disabled-provider fallback for the default model), patch merge semantics (canonical entries win over legacy maps in one patch), the one-time fold (a later reset survives restart; a malformed settings.json is never overwritten), the settlement key (inherit vs never), server-stop continuation per project, and agent access with project browser/device overrides with and without orchestration; typecheck of contracts, shared, client-runtime, server, web, mobile and desktop. Started the built server against a settings.json seeded with legacy projectAutoPullOverrides / projectAgentBrowserAccessOverrides and confirmed the fold produced the generic record with the marker set and derived views intact.

Head a370162a0d. Nonvisual change; behavior is covered by the focused tests above.

Add disabled-provider fallback for defaultModelSelection

resolveProjectSettings applies a project defaultModelSelection without checking isModelSelectionProviderEnabled. serverRuntimeStartup then uses this value for new threads, so a disabled provider can remain selected. Add defaultModelSelection to the existing fallback guard.

resolveSourceControlWriterModelSelection already rejects disabled sourceControlWriterModelSelection.

JJulius MarmingeSep 11, 2026

Fixed in 554fe2a25f. resolveProjectSettings applies the same disabled-provider guard to defaultModelSelection as it did to the text generation model; a project's model on a disabled provider falls back to the environment value and reports source environment. Test added.

CcoderabbitaiBotSep 11, 2026

@juliusmarminge, thanks for the update. The disabled-provider fallback now also covers defaultModelSelection, and the added test covers the expected source behavior.

Preserve both auto_pull states during the legacy fold.

A row with auto_pull = 0 currently creates no defaultAutoPull override and can inherit a true server default. Since the fold then sets projectSettingsFolded, the loss is not retried. Store row.autoPull === 1 for every row. The queried columns exist in the ordered migrations.

✅ Addressed in commit 559eab9

JJulius MarmingeSep 11, 2026

Not applied, on purpose. auto_pull = 0 on the projection row was never a stored preference: the column defaulted to 0 for every project that had not opted in, and main's resolveProjectAutoPull treated it as inherit (legacyAutoPull === true || settings.defaultAutoPull), not as an explicit off. Folding 0 into defaultAutoPull: false for every project would pin all of them off and hide the environment default behind hundreds of overrides. A real explicit off lived in projectAutoPullOverrides[pid] = false, and the fold does carry that. So the fold reproduces exactly what the old resolver computed.

CcoderabbitaiBotSep 11, 2026

@juliusmarminge, thanks for the clarification. The migration preserves the previous resolver behavior:

auto_pull = 1 becomes an explicit enabled override.
auto_pull = 0 remains inherited.
projectAutoPullOverrides[projectId] = false remains an explicit disabled override.

The reported issue does not apply. The finding is withdrawn.

5	Learning: In `apps/server/src/serverSettings.ts`, legacy `projection_projects.auto_pull = 0` means that the project did not opt in to auto-pull. It must remain inherited during migration to `projectSettingsOverrides`. An explicit disabled auto-pull preference is represented by `projectAutoPullOverrides[projectId] = false` and is migrated as `defaultAutoPull: false`.

Note: Learnings are effective only in the context of similar code segments. To apply general coding guidelines, please configure review instructions. You can manage existing learnings in the app.

Make canonical project entries override legacy maps.

A patch can contain both representations for one project. Line 239 merges the legacy value into the canonical replacement entry.

For example, a canonical entry can omit defaultAutoPull to clear it while projectAutoPullOverrides still contains the previous value. The translation restores the cleared value.

Skip legacy-map updates for projects explicitly present in rest.projectSettingsOverrides, or apply canonical entries after all legacy translations.

Fixed in 554fe2a25f. translateLegacyProjectOverridePatch now skips legacy-map entries for any project that has a canonical entry in the same patch, so an omitted key stays cleared. Test: a canonical entry that drops defaultAutoPull alongside a stale projectAutoPullOverrides value for the same project ends without it, while another project's legacy value still translates.

@juliusmarminge, confirmed. The canonical entry now takes precedence over legacy-map values for the same project. The described test covers the cleared-key case and preserves legacy translation for other projects.

Process replayed turn starts outside the current worker.
resumeTurnsAfterCompaction runs on the single makeDrainableWorker loop and waits on sent. OrchestrationEngineService.dispatch publishes the resulting thread.turn-start-requested event, and processEvent enqueues it on that same worker. The worker cannot process the replay while the current item waits for sent. The deferred is therefore settled only after a path that the worker cannot reach, so later turn starts remain queued.
Process replayed turn starts on a separate worker, or use an independent completion signal. A timeout alone does not fix this ordering cycle.

Do not overwrite an invalid settings file during migration.

If decoding fails and an active project row exists, settings remains DEFAULT_SERVER_SETTINGS. The fold then changes that object, and Line 633 replaces the existing file with defaults plus migrated project settings. This deletes unrelated persisted settings and removes the original invalid file that the user could repair.

Track whether the file was absent or decoded successfully. Persist the folded result only in those cases.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces a broad per-project settings capability with persistence migration and runtime changes spanning providers, automation, settlement, streaming, scripts, and agent access. It also adds a static-analysis suppression directive and a new server setting default, so the scope requires human review.

Exclude non-settlement overrides from autoSettlementSettingsKey.

Adding, removing, or reordering a project entry changes the key because it includes every projectId. An existing model-, script-, or Git-only field update does not change the key. When another settlement setting is active, the resulting sweep can perform unnecessary pullRequests.summary or git.branchPullRequest lookups. Filter out entries without settlement fields, sort the retained entries by project ID, and test these cases.

Verified in the layer graph, not a bug. GitLayerLive is composed in the runtime with Layer.provideMerge, and Effect's provideWith builds the dependent layer with the outer context merged in (provideContext → Context.merge), so Effect.serviceOption(ProjectionSnapshotQuery) inside GitManager resolves to the live query in the server runtime; it is none only for the CLI and tests, which is why it is optional. Same pattern ProviderService already uses on main for the projection query and DeviceService.

Fixed in 559eab96fc. A stored null script override is remembered during the fold and blocks that project's aggregate scripts_json from becoming a defaultProjectScripts override. The fold test's legacy project now carries aggregate scripts alongside its null override and asserts they do not come back.

🟡 Medium src/serverRuntimeStartup.ts:233

For an existing auto-bootstrap project, the welcome thread is created without its persisted defaultModelSelection, so a project-specific model is replaced by the server-level model on startup. This path now reads only resolveProjectSettings(settings, nextProjectId) instead of the project's stored selection; restore the persisted project value as the first fallback.

Fixed in 559eab96fc. The bootstrap thread falls back to the project's aggregate defaultModelSelection after the override and before the environment default, so a choice written by an older client keeps applying.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Preserve the aggregate project model when no effective project override exists.

When auto-bootstrap finds an existing project with no active thread, resolveProjectSettings marks defaultModelSelection as "environment". If the environment model is set, the current nullish-coalescing chain skips the project's stored aggregate defaultModelSelection, so the new thread uses the environment model. Select the aggregate value unless the resolver reports an effective project source, and add a regression case with a non-null aggregate model.

This was true of the intermediate commit but is already superseded in a370162a0d: resolveProjectSettings(settings, nextProjectId, existingProject.value) now takes the project record and applies its aggregate defaultModelSelection/defaultThreadEnvMode as the project layer until projectSettingsFolded is set, so an aggregate model beats the environment model here. After the fold the aggregate was copied into the override record on load, so the record alone answers and a reset there sticks. Covered by the new resolver test (aggregate wins unfolded, stored override still beats it, record wins after the fold).

@juliusmarminge, confirmed. The current call passes existingProject.value to resolveProjectSettings.

Before projectSettingsFolded, the resolver applies the aggregate model and then applies stored overrides. After projectSettingsFolded, it uses only the override record. The resolver test covers these precedence cases.

This finding is no longer valid.

5	Learning: In `packages/shared/src/projectSettings.ts`, `resolveProjectSettings(settings, projectId, project)` uses `LegacyProjectSettingsFields.defaultModelSelection` and `LegacyProjectSettingsFields.defaultThreadEnvMode` as project-level values only while `settings.projectSettingsFolded` is false. Stored `projectSettingsOverrides` take precedence before folding. After folding, the resolver ignores aggregate fields so an override reset remains effective.
