ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR introduces cross-process database ownership and guarded update rollback across server startup, CLI authentication, service supervision, desktop behavior, and WSL handling. It also touches authentication code and adds static-analysis suppressions, so the scope and sensitivity require human review. You can add or adjust custom eligibility rules. Learn more. |

Suggested reviewers: Merge Risk: ⚪ Minimal · up to A refused WSL backend now stays stopped and retains its explanation until readiness or a genuine configuration change.

Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The change strengthens protection against competing servers and stale database rollback. Interrupted updates deliberately stop access until recovery, and older service launchers require a local upgrade.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winKeep an ownership-refused WSL instance stopped during reconciliation.
If a secondary WSL backend exits with code 78, the manager clears
desiredRunningand the new callback records the refusal. A laterreconcilewith unchanged settings treats that instance as idle, clears the recorded message, and callsstartagain. Preserve the refusal state until the user explicitly retries or changes the target. This prevents routine reconciliation from repeating a refused launch and hiding its explanation.🤖 Prompt for AI Agents

481-506: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winThe
"released"case does not test lock contention. It passes for an unrelated reason.
mockImplementationOncewraps the first call toacquireServerOwnershipLockafter the spy is installed.Launcher.run()first acquires the launcher lock:acquireServerOwnershipLock(<root>/userdata, { launcher: true }).- The launcher lock uses
server-launcher.sqlite.foreignOwnerholdsserver-owner.sqlite, so the two calls do not contend.- That first call succeeds, and the
finallyblock then releasesforeignOwner. No contention happens at any point.hasBackupistruefor"released".#recovertherefore throws "Manual recovery is required" at the existing-backup check, before any owner-lock acquisition.- The case behaves the same as a plain pre-existing backup. The comment "Real contention occurs, then ownership ends" is false.
If a later change regresses the case "refusal is preserved after the foreign owner stops", this test still passes. The only check on that behavior is in
#startTrial:if (isOwnershipConflict(cause)) throw cause;.Two ways to fix this:
- Make the case reach
#startTrialwith no backup present.- Wrap only the call for the owner lock. Match on the absence of
cli/launcheroptions instead of usingmockImplementationOnce.♻️ Sketch: target the owner-lock acquisition
- .mockImplementationOnce(async (...args) => { + .mockImplementation(async (...args) => { + const [, options] = args; + if (options?.cli || options?.launcher || released) return acquire(...args); try { return await acquire(...args); } finally {Then set
hasBackuptofalsefor"released". With no backup, recovery reachesbackupDatabaseOnce, contends withforeignOwner, and must still end with statusfailedand reasonstate-dir-owned.🤖 Prompt for AI Agents

Note Written by fixed the wsl reconciliation finding in 8c3e061. an ownership-refused target remains stopped with its message intact; changing distro or toggling the backend off and on retries. the existing tests cover those transitions and ordinary preflight retry. also corrected the released-owner launcher test: it now reaches the actual owner-lock contention without an existing backup, then verifies that releasing the foreign owner does not erase the refusal. this is maintainer work requested by maria for #6097, replacing #14694 and #10360. |

two servers could share a t3 home and replace each other's discovery record. exclusive ownership now precedes persistence, competing launches exit 78, and desktop/service retry loops stop. cli mutations, update snapshots and rollback share the ownership boundary; recovery markers prevent stale restores.
fixes #6097. supersedes #14694. scoped discovery/pairing work remains separate.
linux proof: a competing launch refused ownership while the existing web conversation completed another real codex reply. those captures are from 1e69690; a preceding watch restart means they do not prove uninterrupted uptime. at final head a4f3bba, live cli project creation succeeded; a failed live probe exited 78 without changing the sqlite schema. 49 existing tests, server types and scoped lint/formatting passed on blacksmith. two independent exact-head code reviews approved.
unverified in this pass: packaged desktop dialogs, native windows/macos/wsl service execution, crash recovery and managed update trial/rollback.
implemented and reviewed by gpt-6.1-sol through codex in t3 code; runtime evidence captured with agent-browser.
