📝 WalkthroughWalkthroughCredential storage now caches defensive copies, supports asynchronous writes with failure handling, updates cache state after removals, and centralizes platform-specific URL listing. Android pre-authentication retrieval checks metadata before secure reads and falls back on metadata errors. ChangesCredential storage and retrieval
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: ⚪ Minimal · up to Android startup now checks whether the optional pre-authentication secret exists before attempting decryption, while present secrets and fallback behavior remain unchanged. This should only reduce unnecessary Keystore work, and no actionable merge-blocking risk remains after normal checks and review. Sequence Diagram(s)sequenceDiagram

44-63: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy liftFence the handoff against concurrent invalidation.
If a credential or session action clears the handoff while Line 49 awaits
getAllServerCredentials(), Line 62 can publish the earlier credential snapshot after that clear. Route consumers can then accept stale credential presence and skipgetServerCredentials().Use a generation token or equivalent lifecycle revision. Capture it after Line 45. Only prepare the handoff if no later clear changed that revision. Add a deferred credential-load test that clears the handoff before the load resolves.

This PR has been automatically labelled "stale" because it hasn't had recent activity. |
|
@nickmisasi this seems to be solving the same issue as #10056 correct? |
|
@enahum Yes, there is overlap. #10056 fixes the main cold-start bottleneck, and its credential cache also prevents the later route/layout calls from going back to Keystore. #10076 was developed against the earlier implementation. The remaining distinct parts in #10076 are the minimal one-shot presence handoff, stronger invalidation semantics, and skipping an absent optional pre-auth decrypt. I'll rebase it onto current main and reassess whether those changes still justify a separate PR. |

@enahum Correction to my reply above: I moved too quickly from source-level overlap to a performance conclusion. The physical-device evidence does not support it. The earlier #10076 implementation was tested as build 799 and reproduced the original problem. Build 800 then combined #10076 with the DB-first active-server lookup, Android listing skip, and concurrent known-credential reads from #10056, without #10056's long-lived credential cache. It also reproduced the problem on the Samsung SM-F966B. There is another issue with the reduced patch now on this branch: react-native-keychain 10.0.0 already checks the encrypted entry and returns Current The known-good build used a different release-2.43 base plus a larger instrumented source state, so the previous comparison was not controlled. I have moved this PR back to draft and corrected the description. It should remain inactive and should not be merged until a retained-state, same-base physical A/B identifies a stable production delta. |

getGenericPassword already exits early if nothing returns
Given this, I think the PR can be closed.

Status
This PR is not ready for merge. Physical-device testing invalidated the earlier performance conclusion, so it is being kept as a draft while the behavior is isolated with a same-base Samsung A/B.
Summary
The source-level overlap with #10056 is real, but it does not establish a physical fix:
The current reduced two-file patch is also not yet justified as a performance optimization. In react-native-keychain 10.0.0 on Android,
getGenericPasswordchecks the encrypted entry first and returnsfalsebeforedecryptCredentialswhen the entry is absent. An addedhasGenericPasswordpreflight repeats that metadata lookup. Any benefit from avoiding bridge, coroutine, or mutex work is unmeasured and must be benchmarked rather than assumed.Current
maindoes cache positive credentials from initialization, which avoids later layout reads and positive route hits. A route URL missing from an initialized cache can still fall through to a native Keychain read. Existing tests do not cover that negative startup lookup.Next step: a retained-state, same-base physical A/B on the affected Samsung. Until that identifies a stable production delta, this PR should not be reviewed or merged as a performance fix.
No UI or text changed.

Test Results
The current reduced patch has focused unit and static coverage, but those checks do not prove physical-device performance. Builds 799 and 800 also passed their unit, TypeScript, lint, packaging, and emulator launch checks before failing physical validation.
