Problem

Saved desktop connections can become unreadable on macOS and Linux when the Alpha-to-Beta product rename changes Chromium’s encryption identity.

Change

Pin the startup safeStorage name before Electron’s first startup microtask. If a saved catalog was encrypted under Beta, recover it through the existing OS-key helpers, validate the complete catalog, and rewrite it with the current safeStorage key. Recovery checks the encrypted bytes again under the save/clear lock so it cannot overwrite a newer save or resurrect a cleared catalog. Missing keys and invalid recovery data leave the file untouched.

Credit to @jeprecated for the original diagnosis and implementation in #20907. This takeover preserves the author’s commits, merges main, removes the separate resolver test file, and exercises recovery through the catalog store.

Scope and approval

Fixes #20906, with the regression diagnosis confirmed in triage. The maintainer takeover is authorized for this fix. Final approval of the encryption-identity migration remains pending; this PR is left unmerged.

Verification

Validation on head 9967a6761f:

• 30 focused tests pass in 2 files (original: 30 in 3 files). Actual Chromium-format AES-CBC fixtures cover macOS/Linux recovery, reopening the rewritten file, invalid/wrong/missing keys, and concurrent save/clear. OS key access is mocked.
• Fail-before proofs reproduce the rename failure, stale recovery overwrite, invalid recovered catalogs, and wrong-key decryption that passes padding but returns invalid JSON.
• Desktop typecheck, touched-file lint and formatting pass.
• Startup tests observe the pinned name at the first microtask, including unpackaged preview builds; Windows retains its existing path.

The pinned Electron source copies the startup app name into the macOS/Linux crypt configuration. This supports the early-name approach, but is source-level evidence rather than a packaged-app proof.

Independent full-diff review round 1 (Claude Opus 5.5 and GPT-6 Sol) found no blocking code defects. The existing macOS key reader is synchronous; a Keychain authorization prompt during recovery can block the main process until answered. Native verification should check that prompt behavior.

Native verification is incomplete: Electron cannot launch on this Linux machine because libgtk-3.so.0 is missing. No live Linux keyring, packaged upgrade, macOS Keychain, Windows DPAPI, Electron desktop UI, iOS, or Android verification is claimed. Native macOS/Linux upgrade verification and maintainer approval remain required before merge. Recovery requires the Beta key to remain accessible.

Implementation and test work: GPT-6.1 Sol and GPT-6 Astra in the Codex harness; independent review: Claude Opus 5.5 and GPT-6 Sol through T3 Code.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This change alters macOS/Linux safe-storage identity and performs migration of encrypted saved-connection data, including platform keychain/keyring access and startup-name behavior. It also introduces a new static-analysis suppression in a test file, so the runtime and tooling implications warrant human review.

📝 Walkthrough

The desktop now sets a version-derived safe-storage name before startup on macOS and Linux. The catalog store can recover and re-encrypt catalogs using the previous identity when current-identity decryption or catalog validation fails. Writes and clears are serialized.

Changes: Safe-storage identity recovery

Layer / File(s)	Summary
Resolve and set the safe-storage name apps/desktop/src/app/DesktopEnvironment.ts, apps/desktop/src/app/DesktopPreReadyPlatform.ts, apps/desktop/src/app/DesktopPreReadyPlatform.test.ts	The desktop resolves a safe-storage name from the update channel and sets it before startup on macOS and Linux. Tests cover name selection across platforms and application states.
Provide previous-identity decryption apps/desktop/src/app/DesktopSafeStorageIdentity.ts, apps/desktop/src/main.ts	A new service attempts Beta-key decryption for matching Chromium OSCrypt values on macOS and Linux. The catalog store layer receives this service and the Linux browser-secret dependency.
Recover catalogs and serialize updates apps/desktop/src/app/DesktopConnectionCatalogStore.ts, apps/desktop/src/app/DesktopConnectionCatalogStore.test.ts	The store validates decrypted catalog JSON and tries previous-identity recovery when current-identity decryption or validation fails. It re-encrypts recovered data only if the encrypted file is unchanged. A semaphore serializes writes and clears. Tests cover recovery, failure cases, and concurrent operations.

Merge Risk: 🟡 Moderate · up to 44390

Existing preview website logins may be lost after upgrading on macOS or Linux. Address cookie migration or explicitly accept the required sign-ins before merging.

Security architecture risk: 🔵 Low · up to 44390

Recovery is narrowly scoped and protects newer saves and clears from stale rewrites. Remaining uncertainty concerns native key compatibility and the effect of the application-wide identity change on other encrypted state and rollback.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — The added recovery API accepts encrypted bytes, not caller-selected identities, keychain accounts, or paths. It operates only on macOS/Linux when the resolved identity is Alpha, and accepts only the platform-specific encrypted prefix. Its catalog caller uses the configured desktop state directory.

Trust Boundaries and Controls

• observed — Historical key selectors are fixed to Beta. macOS missing or denied key access produces no recovery. Linux approval failures are not silently downgraded, and v11 decryption requires resolved keyring material. Full catalog validation and the ciphertext comparison are additional controls before a recovery rewrite.
• observed — After Linux keyring material is available, the reused helper can retry failed v11 decryption using an empty-passphrase-derived key. Schema validation constrains the resulting document shape but does not establish cryptographic provenance. The native base decryptor's equivalent acceptance behavior was not established, so this is a compatibility-policy uncertainty rather than an established PR-introduced vulnerability.

Resilience and Maintainability Implications

• observed — The inspected tests cover recovery, reopening after rewrite, invalid or missing recovery material, and save/clear races while key lookup waits. They mock OS-key access and current-key writes, so they do not establish packaged native prompt, interruption, or downgrade behavior.

Hardening Proposals

• proposed — Validate a native Beta-to-pinned-identity upgrade and subsequent downgrade with both saved credentials and persistent preview cookies. Include denied key access and interruption during rewrite to establish the supported recovery and rollback outcomes.
• proposed — Make the catalog recovery key policy explicit rather than inheriting all cookie-import compatibility behavior. Establish whether shipped safeStorage catalogs require the empty-passphrase retry before retaining or excluding it.

Explanation

The description includes all required sections. It explains the problem, implementation, scope and approval status, focused verification, limitations, and required native checks. It clearly states that native verification and final approval remain pending.

Full details: Linked Issues check

Explanation

Issue #20906 requires saved catalogs to remain decryptable after the Alpha-to-Beta rename on macOS and Linux. DesktopPreReadyPlatform sets T3 Code (Alpha) before startup yields on those platforms. DesktopSafeStorageIdentity reads the Beta key through the existing Chromium key helpers. DesktopConnectionCatalogStore validates decrypted catalogs, recovers valid Beta catalogs, and rewrites them under the current key. The write lock and encrypted-byte check protect newer saves and clears. Focused tests cover macOS and Linux recovery, wrong and missing keys, invalid catalogs, reopening after rewrite, and concurrent save and clear operations.

Full details: Out of Scope Changes check

Explanation

The changes remain within issue #20906. Startup identity pinning, Beta-key recovery, catalog validation, serialized writes, dependency wiring, and focused tests directly support saved-catalog migration after the rename. No unrelated product behavior is demonstrated.

Taking over this one as maintainer for batch ssh-relay-remote-12. I’ll retain the original fork branch and author history, merge main, simplify tests in a separate pass, and run independent implementation and adversarial reviews. Headless Linux proof will distinguish mocked platform behavior from native desktop verification. No merge is planned.

Reverted in #22219. After this merged, desktop builds could no longer decrypt the existing connection-catalog.json: the sidebar showed "No projects yet", every saved connection sat in "restarting", and the status bar read "0 of 8 updated". The server was healthy; the failure is the safe-storage identity the catalog is now decrypted with, and the Beta-only recovery path does not cover catalogs written under the current identity.

The change itself is wanted. To bring it back it needs a run on a real desktop build that already holds an encrypted catalog, on macOS and Linux, showing the app loading its existing projects and connections after the upgrade, with the captures in the PR body. Happy to re-review once that proof is there.
