Problem

On Windows, additional/managed Codex accounts use private shadow CODEX_HOME directories. Symlinking shared SQLite databases into those shadows allows SQLite to create separate -wal/-shm files beside the symlink. That splits committed SQLite state and can break provider refresh. This addresses #24486 and the remaining legacy-overlay concern in #24426.

Fix

Keep CODEX_HOME private for auth/runtime state and route SQLite databases and sidecars together through CODEX_SQLITE_HOME. Never materialize SQLite-family links into a new shadow.
Refuse pre-existing SQLite symlinks, orphan sidecars and ambiguous mixed shared/private SQLite state before modifying an overlay. Preserve a wholly private SQLite family only when the shared home has no SQLite state; honor explicit nonblank SQLite-home choices without deleting dormant files.
Apply the same SQLite routing and preflight to managed runtime, direct driver, orchestration adapter, and provider-bound terminals. Terminals materialize fresh shadow homes before launch and respect instance > client > host override precedence, including case-insensitive environment names on Windows.
Reject overlapping or physically aliased shared/shadow homes before creating links. Serialize simultaneous materializations of the same shadow within one T3 server process to avoid setup collisions.
Report actionable recovery instructions that cover all Codex writers, shared and shadow SQLite families, and symlink targets. Preserve the authenticated ChatGPT identity while reporting a SQLite setup conflict instead of advising reconnect.

The terminal and mixed-family changes are necessary to close bypasses identified in Gib's Windows review, not additional product features.

Verification

After merging current upstream main on November 8, 2026:

Focused server suites (Codex layout, managed runtime, driver, provider terminal, server settings, ChatGPT auth): 243 passed, 12 platform-specific skips.
Adjacent integration suites (Codex V2 adapter, provider, managed errors, session lock): 158 passed.
Terminal contract suite: 3 passed. 404 passing tests total across these targeted runs.
Server typecheck, targeted lint (0 findings), formatter, and git diff --check passed.
Regression coverage includes mixed SQLite families, unmodified legacy WAL data on refusal, private auth, explicit SQLite-home overrides, terminal environment precedence, Windows lowercase aliases, fresh terminal setup, nested/symlink-aliased homes, and eight concurrent materializations of one shadow. The concurrency test passed 10 repeated runs (80 materialization attempts).
Native Windows Codex CLI 0.167.0 and node:sqlite repros confirmed that the legacy symlink layout creates independent shadow sidecars/stale views, while canonical CODEX_SQLITE_HOME routing creates zero SQLite entries in fresh shadow homes.
Maria independently validated the earlier head end to end on Linux, including real web-app turns and continuation; this does not substitute for CI on the new head.

Limitations: A separate Codex CLI 0.167.0 race when two app-servers cold-start against an entirely empty shared SQLite home is not addressed by this change; a retry after one initializes succeeded, and no shadow state was created. Real managed ChatGPT OAuth on Windows and macOS application runtime have not been exercised end to end on this new head.

Scope

This is a focused correctness fix for the existing SQLite state-splitting defect (#24486), including the provider-terminal path that would otherwise reintroduce it. No automated recovery/migration or cross-process SQLite locking is introduced.

When CODEX_SQLITE_HOME redirects SQLite to another directory, this preflight still rejects legacy *.sqlite-wal files in the shadow home, so provider creation fails before the override-aware environment check runs. Passing {} hides the launch override from codexHomeEnvironment; pass the effective launch environment into this preflight instead.

Nnkcbuilds9d ago

Fixed in f3d14d2e7e. materializeCodexShadowHome now receives the effective launch environment from the managed runtime, driver, and adapter paths, so an explicit nonblank CODEX_SQLITE_HOME is visible during preflight. I also added coverage proving a regular dormant legacy WAL is preserved under an explicit override. Legacy SQLite symlinks are still refused even with an override, matching #24486's structural safety requirement.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — The change keeps SQLite databases and sidecars together by changing default shadow-provider storage routing and refusing unsafe legacy Windows layouts. The new default and recovery policy need human review because affected providers may require recovery before they can start.

Walkthrough

Codex shadow-home setup now validates SQLite databases and sidecars, checks shared and shadow-home paths, and derives CODEX_SQLITE_HOME. Runtime, driver, and terminal paths use the derived environment. SQLite conflicts are surfaced through provider setup and terminal errors.

Changes: Codex SQLite home routing

Layer / File(s)	Summary
SQLite layout validation `apps/server/src/provider/Drivers/CodexHomeLayout.ts`, `apps/server/src/provider/Drivers/CodexHomeLayout.test.ts`	The layout code validates SQLite entries and home paths, serializes materialization by home, and selects the SQLite home. Tests cover path aliases, concurrent setup, legacy links, sidecars, overrides, and preservation of existing data.
Codex runtime environment integration `apps/server/src/provider/CodexManagedRuntime.ts`, `apps/server/src/provider/CodexManagedRuntime.test.ts`, `apps/server/src/provider/Drivers/CodexDriver.ts`, `apps/server/src/provider/Drivers/CodexDriver.test.ts`, `apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.ts`	Runtime and driver paths pass overrides to shadow-home preparation and use the derived Codex environment. The adapter prepares the shadow home when no runtime resolver is configured; otherwise it passes the merged environment without shadow-home preparation. Tests cover routing and conflict behavior.
Terminal environment resolution `apps/server/src/terminal/Manager.ts`, `apps/server/src/terminal/Manager.test.ts`, `apps/server/src/serverSettings.test.ts`	The terminal resolver prepares Codex shadow homes and derives `CODEX_SQLITE_HOME`. Tests cover override precedence, Windows key normalization, and SQLite conflicts.
Conflict error reporting `apps/server/src/provider/Drivers/CodexManagedProvider.ts`, `packages/contracts/src/terminal.ts`, `packages/contracts/src/terminal.test.ts`	Managed-provider snapshots report SQLite conflicts with error status and the conflict message. Terminal environment errors support an optional detail string, covered by encoding and decoding tests.

The production change appears sound. A few new tests would fail on machines that cannot create symlinks, such as Windows without Developer Mode. Add the skip guards to avoid spurious failures in those environments.

Skip this test on non-Windows hosts.

The test creates a database symlink and a -shm sidecar in the shadow home, then expects runtime.resolve to fail with CodexShadowHomeSqliteConflictError. On non-Windows hosts, codexHomeEnvironment accepts this layout and returns successfully, so Effect.flip makes the test fail.

Add the Windows and symlink-support guards used by the related tests.

✅ Confirmed as addressed by @nkcbuilds

Nnkcbuilds9d ago

Fixed the underlying cross-platform behavior in f3d14d2e7e rather than making this Windows-only. #24486 explicitly requires pre-existing SQLite symlinks in auth-overlay shadows to be refused, so codexHomeEnvironment now rejects them on every platform. The runtime regression is therefore valid on Linux/macOS too and now only skips when symlinks are unsupported. This also fixes the failing Linux CI test.

@nkcbuilds Verified in the current source: codexHomeEnvironment rejects SQLite symlinks before the platform-specific branch. The runtime regression correctly skips only when symlinks are unsupported.

The underlying fix addresses the failure and meets #24486. My suggested Windows-only guard is unnecessary. I did not rerun CI.

✅ Addressed in commit a09bf0e

Nnkcbuilds8d ago

Fixed in a09bf0e0a7. The CodexDriver SQLite recovery regression now reuses the repo's symlinksSupported guard and skips when either the host is not Windows or symlinks are unavailable. I also fixed the branch-sync CI regression in CodexManagedRuntime.test.ts by providing NodeCrypto.layer alongside NodeServices.layer, matching the upstream Effect 4.1.2 test-layer migration.

CcoderabbitaiBot8d ago

@nkcbuilds The supplied code confirms skipIf(!windowsHost || !symlinksSupported). This addresses the finding and preserves the Windows-only condition.

Drop the Windows-only guard from the SQLite conflict regression.
The symlink conflict is raised before any platform-specific step. materializeCodexShadowHome runs codexHomeEnvironment before it creates directories or links entries. That scan returns the conflict for a symlinked .sqlite entry before the Windows branch. The test does not spawn a process on this path.
With !windowsHost || !symlinksSupported, Linux and macOS skip the error-snapshot and authenticated-identity assertions. Those hosts do not exercise this path.

test(server): cover Codex SQLite recovery across hosts88f5927

Mmaria8d ago

Note

Written by gpt-6.1-sol on behalf of Maria

Verified in a real dev environment

verified the linux paths at 88f5927444de8d989676cc5d591021470a00c7a9, without source changes. installed and ran fetched github/main (cefb544af3) first in a separate worktree, stopped it, then installed and ran the exact pr head. drove the actual web app with repository playwright and /usr/bin/google-chrome. created a project for a real git repository through the app and ran real gpt-6.1-sol turns through codex cli 0.164.0 and the local proxy.

main created sqlite database/sidecar symlinks when its shadow-home setting was enabled. linux accepted that layout.
the pr refused that same legacy shadow with specific sqlite recovery guidance. it also refused with an explicit sqlite-home override. sqlite link targets and the goals/state database family hashes remained unchanged.
a fresh shadow launched codex with CODEX_HOME pointing at the private shadow and CODEX_SQLITE_HOME at the shared home, confirmed in the actual subprocess environment. no sqlite databases or sidecars appeared in the fresh shadow.
new turns, continuation in the same thread, and a shell git status --short completed successfully. an explicit sqlite-home override created real databases and sidecars in the requested directory, and a new turn completed.
focused checks through blacksmith: 40 passed, 2 windows-only cases skipped, across CodexHomeLayout, CodexManagedRuntime, and CodexDriver. existing ci reports 29 successful contexts on this head.

runtime command transcript

legacy sqlite links refused with recovery guidance in the running app

real codex turn completes through the web client with canonical sqlite routing

Not verified

the original windows split-WAL failure was not reproducible on this linux vm. main reproduced the legacy link layout, not the windows failure itself. native windows WAL placement/recovery still needs windows verification.

managed chatgpt OAuth identity preservation was not exercised through a real login because this environment uses the existing-cli local proxy path. its focused runtime/driver regressions passed, but they do not replace that integration check. macOS, the electron shell, native iOS/android, and relay/tunnel connections were not exercised.

Nnkcbuilds8d ago

Thanks for the Linux runtime verification — I also reproduced the Windows-specific side of #24486 locally.

On native Windows with Codex CLI 0.166.0, I reproduced the underlying SQLite failure directly:

With the legacy shadow layout, opening a shared SQLite DB through a shadow symlink created a separate -wal / -shm pair beside the shadow path.
A minimal SQLite reproduction showed the correctness problem, not just a filesystem conflict: the shared connection had committed schema/data in its WAL, while the connection through the shadow symlink created its own WAL/SHM and failed to see that state (no such table: t).
Running real Codex with the legacy symlink layout created shadow WAL/SHM files across the Codex SQLite database families.
With CODEX_HOME=shadow and CODEX_SQLITE_HOME=shared, the same Codex binary created zero SQLite DB/WAL/SHM files in the fresh shadow; the SQLite state stayed together in the shared home.
An explicit CODEX_SQLITE_HOME override behaved the same way: no SQLite files in the shadow, with DB/WAL/SHM colocated in the override directory.

I also checked the installed T3 trace on this Windows machine read-only, and it contains the production symptom from this issue: CodexShadowHomeEntryConflictError involving a regular shadow goals_1.sqlite-shm.

No live T3 SQLite state was modified during this validation.

So your Linux test covers the real T3 application/turn/continuation path, while this confirms the original split-WAL mechanism and the CODEX_SQLITE_HOME behavior on native Windows.

Note

Written by claude-opus-5-5 on behalf of Gib

Windows verification of this PR at 0dc5a542bb, plus one gap I found and a patch for it.

Environment: Windows 11 Pro 26200, Node 26.12.1, Codex CLI 0.167.0, T3 Code desktop with a second ChatGPT account on shadowHomePath. The installed build shows the production symptom: Cannot create Codex shadow home entry 'goals_1.sqlite-shm' because '<shadow>\goals_1.sqlite-shm' already exists and is not a symlink, with linked *.sqlite files and regular -shm (32,768 B) / -wal (0 B) files for six database families.

Confirmed on Windows

node:sqlite: a connection opened through a file symlink creates its own -shm/-wal beside the link and cannot see the shared connection's committed table (no such table: t). Pre-linking the sidecars does not hold, because SQLite deletes the link, not the target, when it closes.
Codex CLI 0.167.0 app-server with CODEX_SQLITE_HOME set puts all SQLite databases and sidecars there and none in CODEX_HOME. codex-rs/state/src/sqlite.rs resolves all seven families, including thread_history_1 and memories_v2_1, from that directory.
CodexHomeLayout.test.ts: 21/21. vp run check:changed passes format, lint, knip and typecheck. Its only test failures are two cases in CodexManagedRuntime.test.ts:135, which assert a forward-slash path. That assertion is unchanged from main, so they fail on Windows regardless of this PR.

Gap: provider terminals

resolveProviderInstanceTerminalEnvironment (apps/server/src/terminal/Manager.ts) sets CODEX_HOME to the shadow home but not CODEX_SQLITE_HOME. Running codex in a terminal for a shadow-home instance therefore creates private SQLite databases in the shadow home. On the next setup, codexHomeEnvironment sees local SQLite and switches the instance to those private databases.

The patch below resolves the terminal's CODEX_SQLITE_HOME through codexHomeEnvironment, from the same inherited values the provider sees (instance > client > host, so a host CODEX_SQLITE_HOME is honored the same way). While a legacy shadow home blocks the provider, a provider-bound terminal is refused with TerminalProviderEnvironmentError. An earlier version fell back to the shared home instead; review caught that a still-running legacy writer may keep a split WAL, so it now refuses the way the provider does.

Tests in Manager.test.ts extend the existing "prefers $name over the instance environment" table with a hermetic host environment, a shadow-home row and a host-inherited CODEX_SQLITE_HOME row, and add one legacy-shadow refusal case. The new cases fail without the patch and pass with it, and Manager.test.ts passes 77/77 on Windows. Happy to push the branch for a cherry-pick, or open it as a follow-up after this merges.

Two notes on this PR

codexHomeEnvironment uses hasLocalSqlite to switch all database families to the shadow home when any one SQLite file there is a regular file. With a shared state_5.sqlite and only a private logs_2.sqlite, it picks the shadow home, which has no state database, so later launches start private state/goals/history databases. Treating a mix of shared and private state as needing recovery, or an explicit choice, would avoid switching on whatever files happen to exist.
The recovery message tells users to stop processes "using this provider" and back up the shadow home. Other providers may still write the shared database, and a backup that keeps symlinks does not include their target databases. Naming both paths, and saying that the shared database and both homes' sidecars need preserving, would make recovery safer. Retrying or reconnecting cannot clear this refusal.

Add the symlinksSupported guard to this materialization test.

This test calls materializeCodexShadowHome(layout, launchEnvironment). Materialization always runs ensureSymlink for KNOWN_SHARED_DIRECTORIES. An explicit CODEX_SQLITE_HOME override only changes SQLite routing. It does not skip link creation.

If the host cannot create symlinks (for example, Windows without Developer Mode), fileSystem.symlink fails. Materialization then returns CodexShadowHomeFileSystemError, and the test fails before it checks the override or the sidecar. The other materialization tests in this file already use it.effect.skipIf(!symlinksSupported).

Add the symlinksSupported guard to the terminal tests that materialize shadow homes.

resolveProviderInstanceTerminalEnvironment now calls materializeCodexShadowHome for every authOverlay Codex instance. Materialization creates symlinks such as sessions even when a CODEX_SQLITE_HOME override is set. These tests reach that path but are not gated:

Line 2034: the fresh-shadow test. It also asserts readLink(.../sessions).
Line 2077: the CODEX_SQLITE_HOME precedence table.
Line 2152: the Windows lowercase-override test.
Lines 1996-1999: the shadowHomePath row of the configured-home test.

If the host cannot create symlinks, materialization fails with TerminalProviderEnvironmentError, and these tests fail before their assertions. The legacy-symlink test at line 2246 already uses it.effect.skipIf(!symlinksSupported). The mixed-state test at line 2195 fails before any link is created, so it needs no guard.
