Closes https://github.com/pingdotgg/t3code/issues/28437

What's fixed

Switching from a Linux source build to the official AppImage leaves saved connections unreadable because the builds use different protected storage keys. When the current key fails, recover a valid catalog with the source build's T3 Code (Beta) key and re-encrypt it under the existing AppImage identity. A concurrent save wins over the migration.

This follows the recovery approach in Julius Marminge's https://github.com/pingdotgg/t3code/pull/25892, which covers the separate temporary Nightly identity.

Evidence

Linux desktop runtime with synthetic connections and an isolated GNOME keyring. The official .3991 bundle fails; the fixed bundle recovers the catalog, and a restart reads it without rewriting it.

https://github.com/user-attachments/assets/323f2542-2f85-4011-97a3-3ccddd49e6a7

Verified against desktop bundle 21ad298fe983b4076327e7d81c501cff3018a098 inside the .3991 AppImage. The recording shows the real catalog IPC results; no visual UI change is claimed. Head 35b9b9d48e364cefa2c6ed3dadfc426fd78cf0a9 only limits the recovery warning to an error tag; its focused tests and changed-file checks pass.

Not shown: the reporter's NixOS/Hyprland setup or KWallet. Returning to an older source build after migration may require migrating the catalog back.

Implemented with Claude Opus 5.5 in Claude Code and GPT-6.1 Sol in Codex; reviewed and tested with GPT-6.1 Sol in Codex.

12
13	Runtime method:
14	Official 0.1.7-nightly.20261031.3991 x86_64 AppImage, Electron 44.10.0.
15	An added bootstrap wrapper invokes window.desktopBridge.getConnectionCatalog() from the packaged renderer.
16	The baseline retains the official desktop bundle. The fixed run replaces dist-electron and the browser-secret helper with the Boat artifacts for the fixed head; the server and renderer remain the official release.
17	The packaged manifest still names the application t3code and has no productName.
18	A real Electron app named T3 Code (Beta) writes the fixture with --password-store=gnome-libsecret.
19	Its source identity decrypts that fixture; a separate t3code identity cannot decrypt it before recovery.
20	The affected catalog and IPC source files are identical between the official .3991 source and the investigation base.

54	Before implementation, the existing test extension failed with the reported decrypt-catalog error.
55	Before the R1 fix, the empty-passphrase v11 rejection case failed by returning the catalog; after restriction to cbcV11, it passes.

63	Resolved in 21ad298fe983b4076327e7d81c501cff3018a098 by passing only the protected Beta-derived cbcV11 key. Added a failing regression first. No other review findings.
64	The diagnostic suppression for node:crypto in the fixture requires human review under Macroscope policy.
65
66	Limitations:
67	The reporter's NixOS/Hyprland configuration and KWallet were not run. Runtime proof uses GNOME libsecret on corex.
68	This Linux-only change does not recover the separate temporary Nightly identity addressed by Julius's PR #25892, or change macOS/Windows behavior.
69	The recording shows actual desktop IPC output in a terminal, not a visual assertion that every settings view renders.
70	Re-encryption uses the existing AppImage key. Returning to an older source build can require migrating the file back; reverting the code does not reverse the migrated ciphertext.
71
72	Implemented: Claude Opus 5.5 / Claude Code and GPT-6.1 Sol / Codex.
73	Reviewed and verified: GPT-6.1 Sol / Codex.

[gpt-6.1-sol][Codex] on behalf of shivam.

Fixed R2 in 35b9b9d48e364cefa2c6ed3dadfc426fd78cf0a9: the warning now records errorTag: error._tag, and no longer includes the error object or its cause chain.

vp run check:changed passed on the final code: format, lint, both knip passes, typecheck of two packages, and all 12 focused catalog tests. The only change since the recorded Linux runtime at 21ad298fe983b4076327e7d81c501cff3018a098 is this warning attribute, so the recovery and restart evidence still applies.

The runtime used Boat job j_hjw3zkarw67iiajo2ga7, build stage, default machine, VM bx_3as9r46b, attempt 1, exit 0, pinned to 21ad298fe983b4076327e7d81c501cff3018a098. Its desktop bundle and libsecret helper ran inside the official .3991 AppImage on physical corex with an isolated HOME, DBus session and GNOME keyring. The original bundle failed to read the Beta-encrypted fixture. The fixed bundle recovered one synthetic target, profile and credential, re-encrypted the file under t3code, and reopened it without rewriting it. Plain Electron under t3code independently decrypted the migrated file too. The reporter's NixOS/Hyprland setup and KWallet remain unverified.

Earlier R1 is resolved in 21ad298fe983b4076327e7d81c501cff3018a098: recovery passes only the protected Beta-derived cbcV11 key, with a regression proving rejection of empty-passphrase ciphertext.

Walkthrough

On Linux, the connection catalog store attempts recovery with the source-build safe-storage key when normal decryption fails or returns invalid JSON. It validates recovered catalog data and conditionally re-encrypts it. Writes are serialized to protect concurrent catalog updates.

Changes: Linux catalog recovery

Layer / File(s)	Summary
Source-build key recovery `apps/desktop/src/app/DesktopConnectionCatalogStore.ts`, `apps/desktop/src/app/DesktopConnectionCatalogStore.test.ts`	The store resolves the source-build Linux key and accepts decrypted data only when it matches the runtime catalog format. Test fixtures configure Linux hosts, secret lookups, and recovery decryption outcomes.
Catalog recovery and guarded writes `apps/desktop/src/app/DesktopConnectionCatalogStore.ts`, `apps/desktop/src/app/DesktopConnectionCatalogStore.test.ts`, `apps/desktop/src/main.ts`	On Linux, the store tries recovery after decryption failure or invalid JSON. It serializes writes and re-encrypts recovered data only if the catalog has not changed. Tests cover recovery outcomes, concurrent saves, and platform-specific behavior. `main.ts` provides the Linux secret dependency.

Merge Risk: External image Moderate · up to 35b9b

A saved connection catalog can be treated as corrupt and overwritten with an empty one instead of being recovered, and a legacy migration can overwrite a newer save. Both cases are narrow, but they involve data loss and should be fixed before merge.

Full details: Description check

Explanation

The description clearly explains the problem, recovery approach, scope, verification evidence, limitations, linked issue, and implementation details. It uses different headings from the template, but it provides the required information and is sufficiently complete.

Full details: Linked Issues check

Explanation

Issue #28437 requires recovery when the AppImage key cannot decrypt a Linux source-build catalog. The store detects decryption or JSON validation failure, reads the T3 Code (Beta) Linux key, validates the recovered catalog, and re-encrypts it under the current AppImage identity. The document comparison and write semaphore preserve a concurrent set. Linux wiring is present in main.ts. Tests cover recovery, re-encryption, restart reads, invalid data, non-Linux behavior, and concurrent saves.

Full details: Out of Scope Changes check

Explanation

The changes remain within issue #28437. The Linux secret lookup, Chromium key support, store wiring, and tests directly support source-build catalog recovery. No unrelated product behavior or UI change is introduced.

Guard the legacy migration write.
When connection-catalog.json is absent, get() performs asynchronous legacy reads before migration writes the catalog. A concurrent set() can save a newer catalog during that window. The unguarded migration write can then overwrite it.
Run migration persistence under writeLock and re-check that the catalog file is still absent before writing.

Validate successful decryption against the runtime catalog schema.
When Linux decryption returns valid JSON such as {"a":1}, decodeJsonOption accepts it. Source-build recovery is skipped, and get() returns the malformed text. The web consumer then treats it as corrupt and can overwrite the saved catalog with an empty catalog.
Use decodeRuntimeConnectionCatalogDocumentJsonOption for the recovery decision. If validation fails and recovery returns no catalog, raise the protection error instead of returning decrypted.success.
Extend the existing test table with a case that supplies wrongKeyPlaintext: '{"a":1}'. The current malformed-catalog row does not exercise this branch because its safe-storage mock makes decryption fail before validation.

Verified in a real dev environment

verified unchanged head 35b9b9d48e364cefa2c6ed3dadfc426fd78cf0a9 on linux with real libsecret storage, a real git project, and Codex gpt-6.1-sol turns. no mocks or synthetic connection catalog.

installed github/main (5732bbee39) in a separate worktree. created the project and thread through the web client, then completed a real provider turn.
paired the source desktop to that server through settings > environments. its T3 Code (Beta) identity saved one target, profile, and credential using gnome_libsecret in an isolated disposable keyring.
ran the desktop bundles from main and the pr inside the extracted official v0.1.6 appimage runtime, retaining its t3code identity and using the dev web client. main failed with DesktopConnectionCatalogStoreProtectionError during decrypt-catalog; settings showed no saved environments.
the pr recovered that same catalog, re-encrypted it, and connected without pairing again. through the recovered desktop connection, Codex ran git status --short and returned PR_PROVIDER_OK.
switching the environment off and on reconnected. restarting the desktop retained the connection and left the catalog checksum unchanged.

vp run check:changed 575579d68ac4bae09f8426a345d4a3eac1e90c67 passed through blacksmith: format, lint, both knip passes, affected typechecks, and all 12 focused catalog tests. no code changes or pushes were needed.

Not verified

NixOS/Hyprland, KWallet, locked-keyring prompts, SSH/relay/tunnel connections, macOS/Windows, or native iOS/Android clients. concurrent-save recovery was covered by the existing focused tests, not forced through the live client. this used checkout-built desktop bundles in an extracted appimage with a dev renderer; a newly packaged release artifact and returning to the source build after migration were not exercised.
