Saved Windows connections can become unreadable when the shared catalog was encrypted with a different stable or Alpha profile key. Native safeStorage still gets the first attempt for a valid complete envelope; on failure, the catalog adapter authenticates it with accessible legacy profile keys.
Writes authenticate the document currently on disk and use its matching key, including writes before the first read and after another process replaces the file. Malformed, truncated, unknown-key or tampered catalogs are preserved rather than overwritten. Profile keys and encrypted tokens are never replaced. Recovery remains limited to packaged Windows; development and other platforms retain their native paths. Each legacy lookup has a ten-second cancellation deadline; scoped process cleanup is awaited. Key-lookup failures are cached until app restart. This recovers affected catalogs; it does not fix the original key-divergence trigger.
Maintainer takeover of #20152, preserving @bompus's commits. The rebuilt adapter uses Node AES-256-GCM directly and reuses the existing DPAPI key reader, removing the dependency on browser cookie decoding. PR-specific coverage went six repeated matrix rows → five focused cases; a later confirmed stalled-lookup finding added one new behavior case. Final counts are 15 store cases and 35 across four suites, matching the original execution count with distinct behavior coverage.

Focused before/after proof and verification limits.
Human gates before landing: review the production encryption/key-recovery change and recapture native Windows proof on this rebuilt head. This Linux machine cannot verify real DPAPI/PowerShell, Electron safeStorage, packaged startup/upgrade, Windows ACLs, stable/Alpha/current-profile interoperability, V1 native readback, UI recovery or restart persistence. The author's historical native proof does not certify the rebuilt implementation. macOS, native Linux Electron, iOS and Android were not run; this is a desktop Windows service change. No screenshot applies to the nonvisual service behavior. The PR remains unmerged.

On Windows production builds, the desktop catalog store can recover catalogs using keys from either legacy profile. When replacing an existing catalog, it reuses the recovered catalog’s encryption function. Tests cover profile-key variants, write behavior, and invalid ciphertext.

b3e33A stalled Windows key lookup could prevent saved connections from loading or being updated. Bound the lookup before merging, or accept this limited fallback-path risk.
b3e33The recovery preserves authenticated encryption and avoids replacing profile keys or unreadable catalogs. The main remaining risk is recovery availability: a stalled Windows key lookup can leave catalog reads and credential updates waiting indefinitely. Exposure is limited to the affected desktop user's catalog; no privilege expansion was established.

Explanation
Issue #15001 is the active directly linked issue. On packaged Windows, DesktopConnectionCatalogStore first uses native safeStorage, then DesktopWindowsCatalogKey tries accessible t3code and T3 Code (Alpha) keys. The store writes with the key that authenticated the current catalog. Tests cover stable and Alpha recovery, writes before reads, external replacement, and preservation of profile keys and tokens. This supports loading saved connections and registering the local environment without changing profile seeding. The issue's empty-catalog suggestion is separate from the required recovery outcome.
Explanation
The production changes are limited to the #15001 catalog recovery path. The AES-256-GCM adapter, key lookup cache, framing checks, write authentication, and platform gating support recovery and data preservation. The tests cover these behaviors and the existing native and non-Windows paths. No unrelated production feature, profile-key replacement, token replacement, or storage migration is demonstrated.
Explanation
The description is complete in substance. It explains the problem, implementation, scope, approval context, verification results, limitations, remaining human checks, and agent details. It presents this information as prose rather than under the template's explicit headings, but no critical content is missing.

Taking over this one as maintainer for batch ssh-relay-remote-11. I will preserve your commits and this PR, merge current main, trim redundant recovery tests, and run fresh implementation and independent review passes. Verification here is headless Linux; Windows DPAPI, native safeStorage and packaged upgrade behavior will remain explicit human checks. This will remain unmerged.

Add a timeout to the cached profile-key lookup.
readWindowsKey calls unwrapWindowsDpapiKey. That function starts powershell.exe and waits for stdout, stderr, and exitCode with no timeout (ChromiumKeys.ts:180-235). This change puts that call on the catalog get and set paths after native decryption fails.
keys effect never completes. Example causes are a group policy, an antivirus hold, or a stuck DPAPI prompt.store.get and store.set then hang for the rest of the session.Effect.option handles typed failures only, not a process that never exits. Put a bounded timeout on each lookup. A timed-out lookup then becomes Option.none(), and the store returns the existing ElectronSafeStorageDecryptError path.

✅ Addressed in commit 24c644b
Fixed in 24c644b: each profile lookup now has a ten-second cancellation deadline before Effect.option. Existing scoped process cleanup is retained and awaited. One deterministic TestClock/Deferred case proves stalled stable → healthy Alpha recovery, both-candidate failure returning the original native error, cached misses, and preservation of catalog bytes. Removing the timeout produces the expected assertion failure without hanging. All 35 focused cases, desktop typecheck, lint and formatting pass; both fresh full-diff reviewers found no code blockers. This verifies simulated interruption, not a hard wall-clock bound for native Windows process cleanup; native Windows proof and human encryption approval remain outstanding.
@juliusmarminge Thanks for the fix in 24c644b. The per-profile cancellation deadline and deterministic regression test address this finding. Native Windows process cleanup timing remains unverified; the simulated interruption test does not establish a hard wall-clock bound.

I checked the native Windows cleanup path at current head 24c644b5c7e9692a7674d2f0cd5e176b2d97b67d, using isolated synthetic stable and Alpha profiles.
The proof ran the current recovery helper with the real Windows Node process spawner. I deliberately replaced the first profile's subprocess with a PowerShell stall. The production per-profile cancellation deadline interrupted that attempt, and the helper then recovered the synthetic catalog through Alpha's real DPAPI lookup. The interrupted and completed lookup processes were absent when recovery returned. A second read reused the cached lookup results, and both synthetic Local State files remained byte-identical.
The focused native command exited 0. All six recorded wrapper, Node and PowerShell PIDs were absent afterward. The harness passed scoped typechecking, lint, formatting and bundle syntax checks. Current source files and the verification bundle were fingerprinted locally.
This is one controlled native cleanup scenario, not a timing benchmark or a hard wall-clock cleanup bound. Native Electron safeStorage failure was simulated, and its unused module import was replaced only in the verification bundle by a boundary stub that throws if accessed. No packaged application, GUI or real saved-connection profile was tested. Native Windows Node 26.11.0 was used; this does not establish behavior on every supported runtime or Windows configuration. Human approval of the encryption behavior remains separate.
@juliusmarminge, the current-head Windows cleanup evidence is recorded in https://github.com/pingdotgg/t3code/pull/20152#issuecomment-6356697488. It covers one controlled synthetic Node scenario; Electron safeStorage failure was simulated, and packaged startup/upgrade and real-profile interoperability remain unverified.
At head 24c644b5c7e9692a7674d2f0cd5e176b2d97b67d, Macroscope still requests human review of production Windows key recovery, alternate AES-GCM encryption and the static-analysis suppressions. Could you review these changes or identify the appropriate human reviewer, and confirm which remaining integrated Windows checks you need before considering this PR for merge? The earlier timeout thread is resolved; the synthetic proof does not supply encryption approval.
