@LittleLory Could you please review this PR? Thanks! |

@CelsoDeSa Thanks for the work here. Before going deeper into the implementation details, I think this branch should first be rebased onto the latest The current So even though GitHub shows this PR as mergeable, the branch does not seem to be aligned with the current version of the file on Also, a tiny one: I noticed the header comment at the top was changed a bit, and there’s an extra blank line there now 😄 Not a big deal, haha, but I think it looked cleaner before. |

Review Summary
This PR makes comprehensive changes to the OpenViking memory plugin covering security, reliability, and performance. While many improvements are valuable (async logging, session validation, sleep cleanup, abort listener fix), there are several issues that need to be addressed before merging.
Blocking Issues
- TypeScript compile error:
log("WARN", ...)used 6+ times but the function signature only accepts"INFO" | "ERROR" | "DEBUG" - Hardcoded developer path:
/home/celso/.opencodein the security check - Contributor email typo:
convolens.net→convolencs.net(extra 'c') - Undeclared breaking change: Synchronous commit fallback removed despite backward compatibility claims
- Code duplication:
finalizeCommitSuccessbody inlined into two separate call sites
See inline comments for details.

[Bug] (blocking) The original contributor's email was changed from littlelory@convolens.net to littlelory@convolencs.net — note the extra 'c' in "convolencs". This appears to be an unintentional typo that corrupts the original author's attribution.

[Bug] (blocking) This contains a hardcoded developer-specific path /home/celso/.opencode. This is clearly a local debugging artifact and should not be in the codebase. It also creates a security bypass — anyone who places the plugin at this exact path can skip the traversal check regardless of expectedBase.
Remove the !pluginDir.startsWith("/home/celso/.opencode") condition entirely.
Additionally, the security check assumes the plugin must reside under the user's HOME directory. This may break legitimate installations in Docker containers, CI environments, or system-wide setups where the plugin path is outside HOME.

[Design] (non-blocking) The regex /[a-f0-9]{32,}/gi will match UUIDs, session IDs, git commit SHAs, and other hex identifiers that are needed to diagnose errors. For example, an error like "Resource not found: /api/v1/sessions/a1b2c3d4..." would become "Resource not found: /api/v1/sessions/[token]", making it impossible to identify which resource failed.
Consider narrowing the pattern to match known token formats (e.g., Bearer-prefixed strings, sk- prefixed keys) or only applying sanitization to user-facing error returns while preserving full details in logs.

[Bug] (blocking) log("WARN", ...) will cause a TypeScript compilation error. The log() function signature only accepts "INFO" | "ERROR" | "DEBUG" as the level parameter, but this PR introduces 6+ calls with "WARN" — here in acquireLock, in startAutoCommit, checkAndCommitSessions, addMessageToSession retry logic, pollCommitTaskOnce, and waitForCommitCompletion.
Fix: add "WARN" to the level union type:
function log(level: "INFO" | "WARN" | "ERROR" | "DEBUG", ...)| abortSignal?: AbortSignal, | ||
| ): Promise<CommitStartResult | null> { | ||
| ): Promise<string | null> { | ||
| if (mapping.commitInFlight && mapping.commitTaskId) { |

[Design] (blocking) This PR removes the synchronous commit fallback (runSynchronousCommit, detectBackgroundCommitSupport, CommitStartResult type) and now requires the server to support background task API (?wait=false + /api/v1/tasks/). This is a breaking change for older OpenViking versions that don't have the task endpoint.
However, the PR description explicitly claims:
- "All existing configurations work unchanged"
- "Graceful degradation for older OpenViking versions"
Either restore the synchronous fallback, or update the PR description to clearly document this as a breaking change with a migration note.

[Design] (blocking) The body of finalizeCommitSuccess() was removed as a shared function and copy-pasted here and again in waitForCommitCompletion (around line ~1385). This creates duplicated logic that must be kept in sync — if the commit finalization behavior changes, both sites need updating.
Consider keeping this as a shared helper function, which was the original design.

There was a problem hiding this comment.
[Suggestion] (non-blocking) catch (error: any) is used here in newly added code, which contradicts the PR's stated goal of replacing any with unknown for better type safety. This also appears in other new catch blocks (e.g., startBackgroundCommit).
For consistency, use catch (error: unknown) and the error instanceof Error ? error.message : String(error) pattern that's already used elsewhere in this PR.
