Go os.Chmod Windows directory read-only attribute write behavior official documentation
💡 Result:
On Windows, the os.Chmod function in Go has limited functionality compared to Unix-like systems, specifically regarding how it handles file permissions [1][2][3]. According to the official Go documentation, os.Chmod on Windows uses only the 0o200 bit (owner writable) of the provided mode to determine whether to set or clear the file's read-only attribute [1][2][3]. Specifically: - If the 0o200 bit is set (e.g., in 0o600), the read-only attribute is cleared, making the file writable [1][2][3]. - If the 0o200 bit is missing (e.g., in 0o400), the read-only attribute is set, making the file read-only [1][2][3]. - All other bits in the mode are ignored [1][2][3]. Important considerations regarding this behavior include: Directories: While the Go standard library maps this permission bit to the Windows FILE_ATTRIBUTE_READONLY flag, Microsoft documentation notes that this attribute is generally not honored for directories [4][5]. Consequently, attempting to set a directory as read-only via os.Chmod on Windows will not prevent its contents from being modified, and Go's testing suites often skip checks for directory unwritability on Windows for this reason [4][5]. Symlinks: os.Chmod on Windows behaves differently than on Unix regarding symbolic links [6]. While Unix-based os.Chmod resolves a symlink and applies the change to the target file, on Windows it currently applies the attribute change to the symlink itself [6]. Setting the read-only attribute on a symlink may prevent changes to the link target but does not affect the writability of the file the link points to [6]. For compatibility with older versions of Go (1.12 and earlier), it is recommended to use a non-zero mode, such as 0o400 for read-only and 0o600 for read-write [1][2][3].

Skip the chmod-based write-failure tests on Windows.
On Windows, os.Chmod(..., 0o555) does not prevent writes inside directories. EnsureLocalExcludes, writeFileAtomic, and EnsureMergeAttributes can therefore write successfully, causing these require.Error assertions to fail. Skip the three tests when runtime.GOOS == "windows", or use Windows ACL fixtures.

What broke
The daemon writes
.sageox/.gitignoreinto every checkout that has a.sageox/dir and commits it. Its content is a blanket rule:.sageox/there only holds daemon-local cache, and the file is what keeps blue-green GC reclone from seeing a permanently dirty checkout..sageox/curator/marks/and.sageox/curator/synopses/. Once the*rule is on a bubble'smain, the Curator'sgit add -Asilently skips its own save-mark, the server concludes the synthesis never happened, and re-drives it every hour, forever.118956f,82028eb, messagechore: add .sageox/.gitignore to exclude daemon cache files). Already-tracked marks were unaffected because git keeps tracking them, which is why it went unnoticed.Related: #832 fixed a different symptom of the same file (the bare commit swept a ledger wipe along with it). The

.git/info/exclude, never a committed file.kb.EnsureLocalExcludes(new,internal/kb/localexclude.go) writes an ox-managed block into the bubble clone's.git/info/excludeon every reconcile pass (clone and pull). Same managed-block + atomic-write discipline as the existing merge-attrs helper, whose block merger and atomic writer are now shared..git/cannot reach the server or any other clone, and cannot mask a tracked file, so pulled Curator artifacts are unaffected by construction.*: a blanket rule in exclude would be harmless to the server but would hide any new server-written.sageox/subtree from localgit status, recreating the same trap locally. The list is the files the daemon actually writes:/.sageox/meta.json, its atomic temp file,/.sageox/cache/. A unit test pins that no blanket rule sneaks in.TwoPhaseCloneskipsEnsureCheckoutGitignoreCtxformanifest.RepoKindKBwith a code comment saying why. Ledger and team-context kinds are byte-identical to before; a new test pins the team-context kind still commits the file.EnsureCheckoutGitignoreCtx(the "belt-and-suspenders" re-call incloneBubbleis removed).sync_gc.go) unchanged in behavior; comment added that only ledger/team-context workspaces reach it (KB GC inrunKBGCtrashes orphans and never reclones).gitignore.godoc comments scope the committed file to ledgers/team contexts;docs/specs/kb-daemon-sync.mdgets a section on the local-exclude rule and the server-side repair.(3) Repair of the two affected bubbles: server-side
PushWithRetry/git pushcaller targets a ledger or team-context path), and adding one would break the pull-only contract this fix relies on..sageox/.gitignorefrommainin both bubbles. After this PR the daemon pulls that removal cleanly and never re-creates the file, on pull or on a fresh clone. The regression test below drives exactly that sequence.(4) How the commit reached
main: not via a daemon push path in this repocmd/oxandinternal/: the GC carry (gcPushUnpushedCommits) only runs insiderunBlueGreenGC, which only iterates registry team contexts and the ledger. KB paths never enter the workspace registry. The AGENTS.md commit-and-push helper is called only from team-context provisioning.ox doctor --fixgitignore checks iterate ledger and configured team contexts only.ox importpushes to a team context. The managed pull pipeline never pushes.mainand was carried to the server by something outside this repo's daemon (a push from a bubble clone by a human or by a server-side process that reused the clone). I could not determine which from public code, and did not inspect private source.Test Plan
