…kspace Moving a window down past the last workspace on a monitor created the next numbered workspace, while moving up past the first workspace did nothing at all — the keystroke was silently dropped. Workspace switching, bound to the same keys without Shift, has always wrapped in both directions, so the two paths disagreed at both edges. Introduce a MovePastLastWorkspacePolicy setting, exposed as [workspace] movePastLastWorkspace in settings.toml. The default, create, preserves the existing workspace-creating behavior at the end of the list. The wrap case instead wraps to the first workspace, matching switching. Moving up past the first workspace now always wraps regardless of the setting: workspaces are numbered from 1, so there is no lower-numbered workspace to create, and the previous behavior left the keystroke with no effect. Workspace switching deliberately keeps its own always-wrap behavior and does not read the new setting.

When a window or column moves down from the last numbered workspace under the default create policy, the helper first confirms the successor is absent and then requests it with createIfMissing: false, so creation always returns nil and the move wraps to the first workspace instead.

Comment:
**Creation Lookup Disables Creation**
When a window or column moves down from the last numbered workspace under the default `create` policy, the helper first confirms the successor is absent and then requests it with `createIfMissing: false`, so creation always returns `nil` and the move wraps to the first workspace instead.

Valid, and it matters more than it first looks — thank you.
Confirmed: workspaceId(for:createIfMissing:) returns the existing id if the name is mapped, otherwise guard createIfMissing else { return nil } (WorkspaceManager.swift:2413-2419). createNextNumberedWorkspace first requires wm.workspaceId(named: candidateName) == nil, then calls with createIfMissing: false — so the second call can only ever return nil. The create policy can never create.
This is pre-existing on main, not introduced here. The same guard-then-lookup pair is in resolveOrCreateAdjacentWorkspace before this change; I extracted it verbatim into the helper. So "moving down past the last workspace creates the next numbered workspace" was already dead code, and the PR description is wrong to present create as preserving existing behaviour — the existing behaviour is that the move does nothing.
That changes the shape of this PR. Two options:
- Fix the creation path (
createIfMissing: true) socreatedoes what its name says, and keep it as the default. That makes this a behaviour change on the default path, not a no-op default, and it needs runtime confirmation of the creation case before I'd claim it works. - Drop the
createcase and make wrapping unconditional, on the grounds that auto-creation has never actually worked and nobody has reported missing it.
Note the wrap half of this PR is runtime-confirmed — a trace shows a down move resolving sourceWs=3 targetWs=1. Only the create half is affected.
I'd like the maintainers' preference before changing it, since option 2 removes a documented-but-nonfunctional behaviour and option 1 revives one that has never shipped working. Holding the PR as-is until then, and I'll correct the description either way.

Your root-cause analysis is correct and the pre-existing nature of the bug is an important nuance — thank you for tracing it back to main.
From a purely technical standpoint, the tradeoffs are:
Option 1 (createIfMissing: true): Changes wm.workspaceId(for: candidateName, createIfMissing: false) to createIfMissing: true (and drops the now-redundant wm.workspaceId(named:) == nil guard, since the createIfMissing path handles the "already exists" case by returning the existing id). This makes create actually work. The risk is that workspace creation has side effects that haven't been exercised on this path in practice, so runtime confirmation of the full flow is needed before claiming it's correct.
Option 2 (drop create, unconditional wrap): Simpler — remove the MovePastLastWorkspacePolicy enum value (or collapse the enum to a single wrap behavior), remove the settings key, and update the description. The downside is that you're shipping a wrapping-only behavior where the PR advertised a choice; users expecting create from the description get something different. Since the key has never shipped working, there are no users to surprise, but the docs/description correction is non-trivial.
My recommendation leans toward Option 2 for this PR with a follow-up issue tracking proper workspace creation, because:
- Shipping a confirmed-working behavior is strictly better than shipping an unconfirmed one under a tight review timeline
- The
createdefault was never reachable, so no user workflow depends on it - A separate PR for
createcan get proper runtime verification and a focused review
That said, this is a product/maintainer call. The PR is correctly held, and the description correction you mentioned is needed regardless of which option is chosen.

Canonical encoding now always emits [workspace] and movePastLastWorkspace, while the existing golden fixture contains neither, causing canonicalDefaultsMatchGoldenFixture to record a test failure.

**Canonical Fixture No Longer Matches**

Valid — confirmed against the fixture.
Tests/NehirTests/Fixtures/canonical-settings.toml contains no [workspace] table and no movePastLastWorkspace key, while CanonicalTOMLConfig.encode now always emits both. canonicalDefaultsMatchGoldenFixture (SettingsTOMLCodecTests.swift:241) compares the encoded defaults against that fixture verbatim, so it will record a failure.
I did not catch this because I cannot build the test target locally — Swift Testing ships with Xcode, which is not installed on this machine — and the CI run for this branch predates the golden-fixture comparison being reached. That is my gap, not the reviewer's.
The fixture needs regenerating with the new section. I will do that together with whatever comes out of the creation-path question in the other thread, since that decides whether movePastLastWorkspace keeps a create case at all and therefore what the fixture should contain.
There was a problem hiding this comment.
That sequencing makes sense — the fixture should be regenerated after the creation-path question is settled, since whether the create case survives determines the exact output. Good call waiting rather than regenerating twice.
One thing to keep in mind when you do regenerate: make sure you run the test suite (swift test) with the updated fixture in place before committing, so the golden comparison is actually passing and not just the file contents looking plausible by eye. Given that local Swift Testing isn't available on your machine, you might need to push a draft commit and rely on CI to confirm it.

| Add a "Move Past Last Workspace" setting that controls what happens when you move a window down past the last workspace on a monitor. The default, "Create New Workspace", keeps the existing behavior of creating the next numbered workspace. Choosing "Wrap to First Workspace" instead moves the window to the first workspace, matching how workspace switching already wraps. Moving a window up past the first workspace now wraps to the last workspace instead of doing nothing. |

Greptile Summary
Adds a persisted workspace-edge movement policy and exposes it in Behavior settings, while changing upward edge moves to wrap.
Confidence Score: 2/5
The PR is not safe to merge until create mode can create its successor workspace, workspace unknown keys are preserved, and the canonical fixture is updated.
The default movement policy always falls through to wrapping because creation is disabled for an absent target; the new TOML table also drops unknown workspace keys during round trips and breaks the exact canonical serialization test.
