Review Change Stack

Walkthrough

This change migrates Cline to session storage, adds resilient Antigravity parsing and scoped decryption, expands Codex database and export handling, strengthens Cursor recovery and workspace deletion, adds platform-aware archive naming, supports cancellable downloads, and groups OpenCode global sessions by directory.

Changes

Antigravity resilience and decryption

Layer / File(s) Summary
Scoped decryption and diagnostics
src/lib/antigravity-keychain.ts, src/lib/antigravity-db.ts, src/lib/antigravity-transcript-history.ts, src/lib/antigravity-trajectory.ts, src/ui/lib/antigravity-server.ts
Antigravity now uses request-scoped decryption capabilities. Protobuf and JSONL readers preserve valid records and return bounded diagnostics.
Source discovery and validation
src/lib/antigravity-exporter-types.ts, src/lib/antigravity-*.test.ts
Discovery includes the Antigravity CLI root. Tests cover corrupted records, diagnostics, and decryption state.

Cline session storage

Layer / File(s) Summary
Session storage migration
src/lib/cline-db.ts, src/lib/cline-exporter-types.ts, src/lib/cline-test-helpers.ts, src/lib/cline-transcript.ts
Cline reads session metadata and message files instead of legacy task-history files. Deletion removes session data and SQLite index records.
Application integration
src/lib/conversation-data/..., src/ui/lib/cline-server.ts, src/ui/routes/cline*
Adapters and server functions use clineDataDir, accept session identifiers, and pass Cline platform metadata to exports.

Codex database and exports

Layer / File(s) Summary
Database compatibility and cleanup
src/lib/codex-browser-types.ts, src/lib/codex-browser-db.ts, src/lib/codex-browser-db.test.ts
Codex validates database schemas and row types, supports batch browsing and fallback sources, performs transactional cleanup, and reports stale session-index entries.
Stable rollout exports
src/lib/codex-rollout-snapshot.ts, src/lib/codex-browser-export.ts, src/lib/codex-browser-export.test.ts
Exports copy stable rollout snapshots, retry mutations, continue recoverable batch entries, and write export manifests.

Cursor recovery and workspace deletion

Layer / File(s) Summary
Managed database recovery
src/lib/cursor-db.ts, src/lib/cursor-recovery.ts, src/lib/cursor-id.ts
Cursor uses retry-wrapped reads and transactions, discovers CLI transcripts, performs exact-range bubble operations, and rolls back failed recovery mutations.
Workspace deletion UI
src/ui/lib/cursor-server.ts, src/ui/routes/cursor.index.tsx, src/ui/components/cursor-workspaces-table.tsx
Cursor supports selecting and deleting multiple workspaces, including workspace bucket and history cleanup.

Shared exports and downloads

Layer / File(s) Summary
Platform-aware archives
src/lib/ui-export-archive.ts, src/lib/conversation-zip-export.ts, src/ui/lib/source-session-export-server.ts, src/ui/lib/*-server.ts
Archive names include platform identifiers and project or workspace metadata.
Cancellable downloads
src/ui/lib/download.ts, src/ui/components/export-dialog.tsx, src/ui/routes/*
URL downloads support cancellation, retry interruption, lifecycle states, and route-level cancellation ownership. Inline downloads report lifecycle states.

OpenCode workspaces and metadata

Layer / File(s) Summary
Directory-based OpenCode workspaces
src/lib/opencode-db.ts, src/lib/opencode-db.test.ts
Global OpenCode sessions are grouped by directory and selected through directory-specific workspace keys.
Package and documentation updates
package.json, README.md
The package version and TanStack Router packages are updated. Documentation records current storage paths and database behavior.

Invalidate the workspace list after a failed batch deletion too.

deleteCursorWorkspacesFn in src/ui/lib/cursor-server.ts Line 350 deletes groups sequentially and rethrows the first error. Groups that were deleted before the error stay deleted. The mutation invalidates ['cursor-workspaces'] only in onSuccess, so after a partial failure the table keeps showing workspaces that no longer exist. A retry on those rows then fails with Cursor workspace not found.

Invalidate in onSettled instead.

🐛 Proposed fix
-        onSuccess: async () => {
-            await invalidateCursorQueries();
-            setPendingDelete(null);
-        },
+        onSuccess: () => {
+            setPendingDelete(null);
+        },
+        onSettled: invalidateCursorQueries,
     });

1633-1688: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Detach the history database even when ATTACH bookkeeping is inconsistent.

Two points in this block need attention.

  1. historyAttached is assigned inside the transaction callback. If transactionDb.query('ATTACH DATABASE ? AS codex_history').run(historyDbPath) succeeds but a later statement throws, the rollback runs and the finally block detaches. That path is correct. If the ATTACH statement itself throws after the schema is partially attached, historyAttached stays false and the alias leaks on the pooled connection. Set the flag before the ATTACH call, or wrap DETACH so it always runs.
  2. The finally block calls db.query('DETACH DATABASE codex_history').run() without a try/catch. If DETACH throws, it replaces the original error from the transaction. Callers then see a detach error instead of the real cause.
🛡️ Proposed fix
             const historyDbPath = resolveCodexHistoryDbPath(dbPath);
             if (hasRegularFile(historyDbPath)) {
+                historyAttached = true;
                 // SQLite coordinates this transaction across the attached database for normal commits. A process
                 // crash during WAL commit is not claimed to be crash-atomic across both database files.
                 transactionDb.query('ATTACH DATABASE ? AS codex_history').run(historyDbPath);
-                historyAttached = true;
             }
     } finally {
         if (historyAttached) {
-            db.query('DETACH DATABASE codex_history').run();
+            try {
+                db.query('DETACH DATABASE codex_history').run();
+            } catch (detachError) {
+                console.warn('[spiracha:codex] detach codex_history failed', detachError);

Reuse the computed browseEntries instead of recomputing the skipped count.

Line 550 recomputes manifestEntries.filter((entry) => entry.status !== 'exported').length. Line 518 already computes the same value as manifestEntries.length - exportedCount. Hoist exportedCount and skippedCount above the try result so both the manifest and the return value use one source.

Inline comments:
In `@src/lib/antigravity-db.test.ts`:
- Around line 281-283: Update the test for resolveAntigravityRoots to
temporarily clear SPIRACHA_ANTIGRAVITY_DIRS and SPIRACHA_ANTIGRAVITY_DIR before
asserting the default discovery root, then restore each variable’s original
value afterward, including when the assertion fails.

In `@src/lib/antigravity-db.ts`:
- Around line 349-391: Update readAntigravityProtobufRecords to avoid calling
appendBytes for every incoming stream chunk, since that repeatedly copies the
entire pending buffer. Accumulate chunks without copying and concatenate only
when consumeProtoRecord requires contiguous bytes, or compact an existing buffer
using a read cursor only after successful consumption; preserve bufferOffset,
record parsing, diagnostics, and truncated-input handling.
- Around line 315-347: Bound protobuf diagnostics appended by consumeProtoRecord
to a fixed maximum, including the invalid-field resynchronization path, and skip
further diagnostic objects once the cap is reached while continuing to advance
and scan records. Apply the same guard to the related diagnostics append path
around readAntigravitySummaryIndexWithDiagnostics, preserving existing parsing
behavior and returned diagnostics up to the limit.

In `@src/lib/antigravity-transcript-history.test.ts`:
- Around line 50-70: Extend the tests around readAntigravityJsonlFile with a
transcript containing a JSON record larger than the stream chunk size, followed
by valid records. Ensure the test exercises consumeJsonlFragment across multiple
fragments, including pending accumulation, lineBytesSeen, and lineOffset
progression, and assert the parsed records plus diagnostic byte offsets.

In `@src/lib/antigravity-transcript-history.ts`:
- Around line 146-187: Update consumeJsonlFragment to account for stripped CRLF
bytes by destructuring lineTerminatorBytes and including those bytes in
state.lineBytesSeen when processing a fragment that continues without a newline,
while preserving existing newline offset advancement and parsing behavior.

In `@src/lib/cline-db.ts`:
- Around line 518-523: The delete result in the session-deletion flow should
report only sessionDir in deletedFiles; remove the sessions.db path derived from
indexDeleted. If callers need to know whether the index row was removed, expose
indexDeleted through a separate result field and update deleteClineConversation
and deleteClineTasksFn to use that field without treating the database as
deleted.
- Around line 446-452: The listing flow eagerly parses every session transcript
through listClineTranscripts, causing repeated full scans when
listClineWorkspaceGroups and listClineTasksForGroup are called by
listClineConversationsForPath. Change this flow to reuse parsed transcripts per
dataDir within a request, or derive the required metadata and counts from the
session index without loading message payloads, while preserving the existing
list results.
- Around line 401-409: Update readClineTranscriptFromEntry to return a
transcript with an empty messages array when parseSessionMessages produces no
renderable messages, rather than returning null. Also update the session
handling around the isSafeSessionId check at src/lib/cline-db.ts lines 144-161
to retain sessions with missing workspace_root or cwd by using the fallback
worktree; reject only unsafe session IDs.
- Around line 495-505: Update readClineTaskTranscript to resolve the validated
taskId’s session entry directly instead of calling listClineSessionEntries and
scanning all sessions. Ensure the direct metadata read handles a null readJson
result by widening parseSessionEntry’s input to JsonValue | null or guarding
before calling it, then preserve the existing readClineTranscriptFromEntry
behavior.
- Around line 337-345: In the message iteration around parseStoredMessage,
remove the redundant asObject(value) assignment and null guard after the
parseStoredMessage check; retain the existing early return for invalid parsed
messages and leave the remaining processing unchanged.
- Around line 373-384: Update deleteClineSessionIndex and the surrounding Cline
session deletion flow to catch SQLite cleanup failures so rm proceeds regardless
of errors such as missing schema or SQLITE_BUSY. Extend DeleteClineTaskResult
with an explicit index-cleanup status and populate it for both successful and
failed cleanup, rather than using false alone to represent the outcome.

In `@src/lib/codex-browser-db.test.ts`:
- Around line 1467-1491: Make the concurrency tests deterministic by removing
the wall-clock-dependent lock holder timing and synchronizing on observable lock
state before invoking deleteCodexThread. In the competing-writer test, replace
the exact one-process deletion assertion with an invariant that the union of
both reported ID arrays is a subset of [threadId], while preserving the final
row-count assertion that confirms the thread was deleted.
- Around line 1179-1199: Remove the initial getThreadBrowseData invocation
wrapped in expect(...).toThrow and retain only the try/catch invocation in the
compatibility test. Within that try/catch, preserve the
CodexDbCompatibilityError instance, code, missingColumns, and message
assertions.
- Around line 1201-1231: Replace the quadratic results.indexOf assertion in the
batch browse test with a direct comparison of results.map(result =>
result.threadId) against ids. Extend the fixture IDs so the parent and child
threads are separated by more than SQLITE_DELETE_BATCH_SIZE entries, and assert
the cross-chunk browse output preserves the expected relationship without
duplicate childEdges.

In `@src/lib/codex-browser-db.ts`:
- Line 2332: Extract a shared helper for the cleanup result construction used by
deleteCodexThread, deleteCodexThreads, and deleteCodexProject. Have it accept
sessionIndexResult, options.deleteSessionFiles, and result.deletedThreadIds,
then return the common cleanup object and merged deletedThreadIds array; replace
all three duplicated constructions while preserving their existing behavior.
- Around line 284-305: Unify validation in parseDynamicToolRow,
decodeThreadGoalRow, and decodeThreadSpawnEdgeRow by extracting a shared
row-decoder factory for the requiredString, requiredNumber, and nullableNumber
helpers, parameterized by table name. Have each decoder collect all invalid
field names while parsing, then throw one CodexDbCompatibilityError after
validation instead of failing on the first field; preserve the existing
valid-value decoding behavior and table-specific field paths.
- Around line 415-419: Protect getSchemaTableColumns by validating tableName
against the allowed schema-table identifiers before interpolating it into the
PRAGMA statement. Reuse the existing CODEX_BROWSE_SCHEMA_PROFILE keys or an
equivalent strict identifier allowlist, and reject any value that is not
permitted before executing the query.
- Around line 2069-2094: Deduplicate spawn edges returned across chunk queries
by creating one shared seen-edge Set in readThreadBrowseDatabaseData before the
chunk loop, passing it into readBrowseRelations, and skipping already-seen edges
using a stable edge identifier before appending to childEdges or updating
parentThreadId.
- Around line 529-545: Update withSqliteTransaction to check db.inTransaction
before issuing ROLLBACK, and log any rollback failure instead of silently
swallowing it; preserve propagation of the original callback error.
- Around line 2128-2167: The batch flow should load session-index names and the
session-file map once in getThreadBrowseDataBatch, then pass those cached
results into buildThreadBrowseData and the fallback lookup. Update
applySessionIndexThreadNames and related fallback resolution to reuse the
supplied data rather than stat session_index.jsonl, rebuild the name map, rescan
entries for missing IDs, or recompute the session-file index fingerprint per
thread.
- Line 582: Move retry handling out of withWritableDb so the writable callback
is not rerun on the same connection after partial state changes. Update the flow
around runWithSqliteRetry and deleteThreadIds to restore the codex_history
attachment state before retrying, or create a fresh database connection for each
retry.

In `@src/lib/codex-browser-export.test.ts`:
- Around line 389-444: Add an assertion in the partial-batch export test for
renderCodexThreadsDownload that verifies the returned
download.skippedThreadCount equals 1, alongside the existing manifest count
assertions.

In `@src/lib/codex-browser-export.ts`:
- Around line 245-256: Update isArchiveWideFailure to inspect the wrapped
error.cause code in addition to the top-level code, including causes containing
ENOSPC, EACCES, or EIO and other ARCHIVE_WIDE_FILE_ERROR_CODES. Preserve the
existing CodexDbCompatibilityError handling and return false for errors without
a matching string code.

In `@src/lib/codex-browser-types.ts`:
- Around line 244-252: Update DeleteThreadsResult and its producers
deleteCodexThread, deleteCodexThreads, and deleteCodexProject to expose only one
deletedSessionFiles array, removing the duplicate top-level or cleanup field
consistently; if external consumers require the existing field, retain it only
as a deprecated compatibility alias.

In `@src/lib/codex-rollout-snapshot.test.ts`:
- Around line 12-56: Add two test cases to the Codex rollout snapshot suite
covering CodexRolloutSourceError: make stat reject an ENOENT error and assert
the result code is CODEX_ROLLOUT_MISSING, then make copy reject an EACCES error
and assert the result code is CODEX_ROLLOUT_UNREADABLE with cause set to the
original error.
- Around line 4-10: Update the identity helper to import and use the exported
CodexRolloutIdentity type from codex-rollout-snapshot instead of deriving it
through copyStableCodexRollout’s return type.

In `@src/lib/codex-rollout-snapshot.ts`:
- Around line 108-162: Extract the repeated CodexRolloutSourceError construction
into a shared runSourceOperation helper, then use it for both operations.stat
calls and operations.copy in copyStableCodexRollout. Preserve the existing
missing-versus-unreadable error code selection and sourcePath/threadId context.

In `@src/lib/conversation-data/cline-adapter.ts`:
- Around line 26-27: Update getDataDir to use the shared
ConversationDataLocations type for its options parameter, preserving the
existing optional locations and clineDataDir fallback behavior while removing
the duplicated inline type.

In `@src/lib/conversation-zip-export.test.ts`:
- Line 73: Update the temporary-artifact assertion in the export test to filter
names using the platform temporary-path prefix, including cline_, rather than
fallbackProjectName. Keep the expectation that no matching artifacts remain
after export.

In `@src/lib/cursor-db.test.ts`:
- Around line 865-881: The test around withCursorReadonlyDb does not reliably
exercise runWithSqliteRetry because the WAL writer permits concurrent reads.
Change the lock setup or assertions so the read is blocked and must retry, and
verify an observable retry outcome or signal; ensure the test fails if
withCursorReadonlyDb no longer uses the retry wrapper.

In `@src/lib/cursor-db.ts`:
- Around line 1799-1805: Update readCursorThreadTranscriptWithAgentFiles to
accept optional pre-resolved transcriptDirs, using them when provided while
retaining its existing discovery fallback for standalone callers. In
renderCursorDownload, call findCursorTranscriptDirsForComposerIds once for all
selected composer IDs and pass the resulting directories to each
readCursorThreadTranscriptWithAgentFiles invocation.
- Around line 1660-1679: Update readCursorCliTranscriptThread to inspect
transcript file mtimes before calling readCursorAgentTranscript, and skip
parsing when the newest file mtime is not greater than options.updatedAfterMs.
Preserve parsing when updatedAfterMs is undefined or any transcript file is
newer, while retaining the existing transcript-content filtering afterward.

In `@src/lib/cursor-id.ts`:
- Around line 19-22: Add a concise comment adjacent to getCursorBubbleKeyRange
documenting that the semicolon terminator is the next code point after the colon
and that the half-open range requires BINARY collation on the key column.

In `@src/lib/cursor-recovery.test.ts`:
- Around line 117-162: Update the two lock-retry tests around
withCursorWriteTransaction and recoverCursorWorkspaceGroup to derive lock-hold
durations from the retry constants used by runWithSqliteRetry. Give the
successful transaction test an explicit, comfortably short hold duration below
the minimum retry budget, and give the exhaustion test a duration above the
maximum budget, avoiding hard-coded timing literals while preserving both
expected outcomes.
- Around line 424-426: Update the test setup around groupCursorBuckets and
holdCursorWriteLock to select the intended bucket by its ID, specifically
bucket-second, instead of using group!.buckets.at(-1). Confirm the selected
bucket is not the first one processed by pruneWorkspaceBuckets; if it is, choose
the bucket the implementation mutates last so the rollback path is exercised.

In `@src/lib/cursor-recovery.ts`:
- Around line 736-797: Update the Cursor workspace deletion confirmation
descriptions in the cursor index and workspace route views to explicitly state
that local file history under the workspace folders will also be permanently
deleted, alongside the existing thread, transcript, and storage warnings; keep
deleteCursorWorkspaceHistory behavior unchanged.
- Around line 112-133: Deduplicate composer IDs before batching in both
readBubblesForComposerIds and countBubblesForComposerIds, then use the unique
IDs to initialize results and build the UNION ALL queries so duplicate inputs
cannot produce repeated bubble rows.

In `@src/lib/cursor-test-helpers.ts`:
- Around line 284-296: Update holdCursorWriteLock so the child script receives
the database path and duration through stable named environment variables, or
validates the positional arguments before use; ensure the database path is
passed to Database and durationMs is parsed and validated as a finite
nonnegative number before Bun.sleep.
- Around line 297-323: Update the child-process readiness helper to continuously
capture stderr and include it with stdout when reporting premature exit; also
bound the readiness loop by racing each reader.read() or the overall wait
against a timeout, killing and awaiting the child before throwing a clear
timeout error.

In `@src/lib/opencode-db.ts`:
- Around line 465-493: The global workspace query and its result-processing flow
must exclude rows whose session directory is empty, emit a diagnostic for each
rejected global-session row, and only then call toWorkspaceGroup. Update the
logic around globalWorkspaceRowsQuery and toWorkspaceGroup while preserving
valid directory grouping.

In `@src/ui/components/cursor-workspaces-table.tsx`:
- Around line 137-156: Hoist the row-ID accessor used by DataTable out of the
component so getRowId retains a stable identity across renders, while preserving
row.key as the returned identifier. Do not alter the tableColumns logic; the
requested change is limited to stabilizing getRowId in the DataTable
configuration.

In `@src/ui/components/cursor-workspaces-table.vitest.tsx`:
- Around line 193-217: Add a regression case in the multi-selection test around
CursorWorkspacesTable that dispatches both row checkbox clicks within a single
act batch, without an intervening render, then verifies Delete selected
workspaces receives both workspaces. Keep the existing separate-event coverage
intact.

In `@src/ui/components/export-dialog.tsx`:
- Around line 204-211: Update the footer Cancel button to call
handleOpenChange(false) instead of onOpenChange(false), ensuring the existing
cancelActiveDownloads flow runs when closing during a URL export.
- Around line 260-268: Update submitExport and the dialog-close handling to
invalidate active submissions when the dialog closes, then verify the submission
token after loadEvidence and before downloadTextFile so cancelled continuations
cannot download. When focused-mode preparation returns no result, set
downloadState to 'failed' instead of leaving it at 'preparing'.

In `@src/ui/lib/antigravity-server.ts`:
- Around line 109-116: Update the renderConversation error handling to
distinguish decryption-capability acquisition failures from renderer,
unreadable-file, and parser errors. Only convert the specific decryption error
to transcriptLocked or the unlock-Keychain result in the later unencrypted path;
propagate all other rendering errors unchanged.

In `@src/ui/lib/cline-server.ts`:
- Around line 7-19: Centralize the session-ID validation pattern in the shared
Cline module, preferably as CLINE_SESSION_ID_PATTERN in cline-exporter-types.ts,
and update isSafeSessionId in cline-db.ts plus taskSchema, exportTaskSchema,
exportTasksSchema, and deleteTasksSchema in cline-server.ts to reuse it instead
of defining duplicate regexes. Keep the pattern Unicode-enabled and non-global
so shared validation remains consistent.

In `@src/ui/lib/cline-server.vitest.ts`:
- Around line 6-21: Add a negative test for deleteClineTaskFn or
getClineTaskDetailFn using a traversal-style task ID such as ../../etc, and
assert that the returned promise rejects through the mocked validator path. Keep
the test focused on verifying unsafe IDs are rejected before reaching the
handler.

In `@src/ui/lib/cursor-server.vitest.ts`:
- Around line 306-349: Add a failure-path test alongside
deleteCursorWorkspacesFn where the second pruneCursorThreadsMock invocation
rejects after the first succeeds. Assert the first workspace’s deletion steps
and result processing occur, then verify deleteCursorWorkspacesFn rejects with
the propagated error.

In `@src/ui/routes/cursor.index.tsx`:
- Around line 24-34: Guard the Cursor workspace deletion dialog against an empty
pending selection: when pendingDelete is an empty array, keep the dialog closed
and do not invoke deleteCursorWorkspacesFn. Update the dialog-opening logic and
related description handling around getWorkspaceDeleteDescription so only a
non-empty workspace selection is treated as pending deletion.

Isolate the discovery test from environment overrides.

resolveAntigravityRoots returns the configured list when SPIRACHA_ANTIGRAVITY_DIRS or SPIRACHA_ANTIGRAVITY_DIR is set. If either variable exists in a developer shell or CI job, this test fails even though the default roots are correct. Clear both variables for the test and restore them afterward.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Bound the diagnostics array during byte-wise resynchronization.

consumeProtoRecord pushes one diagnostic and advances a single byte for every invalid field. For a large corrupt or non-protobuf file, this produces one diagnostic per byte. A 100 MB damaged file produces about 100 million diagnostic objects, each holding a formatted message string. The reader then holds all of them in memory and returns them to callers.

Add a cap on the number of protobuf diagnostics, and stop appending after the cap while still scanning.

🚀 Performance & Scalability | 🔵 Trivial | ⚖️ Poor tradeoff

Reduce repeated buffer copying in the stream loop.

appendBytes allocates and copies the whole pending buffer for every chunk. When a record spans many chunks, the pending buffer can approach the 8 MiB limit, and each new chunk copies the full pending content. The cost grows quadratically with the number of chunks per record.

Collect pending chunks in an array and concatenate only when the parser needs contiguous bytes, or track a read cursor and compact the buffer only after a successful consume pass.

Add a test for a record that spans stream chunks.

Both new tests use small files, so Bun.file(...).stream() delivers the content in one chunk. The multi-fragment logic in consumeJsonlFragment — pending accumulation, lineBytesSeen, and lineOffset progression — is therefore not exercised. Write a transcript with a single JSON line larger than the stream chunk size, followed by more valid lines, then assert the records and the diagnostic offsets.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Fix byte-offset drift on CRLF input in the streaming parser.

consumeJsonlText strips the trailing \r before it calls consumeJsonlFragment. fragmentBytes therefore excludes the \r, and state.lineOffset += state.lineBytesSeen + 1 counts only the \n. For a CRLF transcript, every line offset drifts by one additional byte, so diagnostics point to the wrong position for later lines.

parseAntigravityJsonlText does not have this defect, because it measures the pre-strip slice at Line 111. Align the streaming path with it.

🐛 Proposed fix
 type JsonlFragmentInput<T> = {
     diagnostics: AntigravityParseDiagnostic[];
     fragment: string;
     hasNewline: boolean;
+    lineTerminatorBytes: number;
     maxLineBytes: number;
     parse: (line: string) => T;
     records: T[];
     state: JsonlStreamState;
 };
-    state.lineOffset += state.lineBytesSeen + 1;
+    state.lineOffset += state.lineBytesSeen + lineTerminatorBytes;
     while (start < text.length) {
         const newline = text.indexOf('\n', start);
         const hasNewline = newline >= 0;
         const end = hasNewline ? newline : text.length;
-        const fragment = text.slice(start, end).replace(/\r$/u, '');
-        consumeJsonlFragment({ ...input, fragment, hasNewline, state });
+        const raw = text.slice(start, end);
+        const fragment = raw.replace(/\r$/u, '');
+        const strippedBytes = Buffer.byteLength(raw) - Buffer.byteLength(fragment);
+        consumeJsonlFragment({
+            ...input,
+            fragment,
+            hasNewline,
+            lineTerminatorBytes: strippedBytes + 1,
+            state,
+        });
         start = hasNewline ? end + 1 : text.length;
     }

Destructure lineTerminatorBytes in consumeJsonlFragment and add the stripped bytes to state.lineBytesSeen when the fragment continues without a newline.

Share one session-ID pattern between the server schemas and cline-db.

The regex /^[A-Za-z0-9_-]+$/u appears four times in this file and again as isSafeSessionId in src/lib/cline-db.ts at line 74. That guard controls which IDs reach path.join(dataDir, 'sessions', taskId). If one copy is later relaxed, the validation contract diverges between the transport layer and the storage layer.

Export the pattern (or isSafeSessionId) from the Cline module and reuse it here.

Place CLINE_SESSION_ID_PATTERN in src/lib/cline-exporter-types.ts and use it for isSafeSessionId in src/lib/cline-db.ts. A module-level RegExp with the u flag and no g flag is safe to share, because it holds no lastIndex state.

Add a negative test for the new ID validation.

The mock now runs the Zod validator before the handler. That makes the widened taskId pattern testable, but no test asserts rejection. Add a case that calls deleteClineTaskFn or getClineTaskDetailFn with a traversal-style ID such as '../../etc' and expects the promise to reject. This locks the guard that keeps unsafe IDs out of path.join(dataDir, 'sessions', taskId) in src/lib/cline-db.ts.

Add a failure-path test for batch workspace deletion.

deleteCursorWorkspacesFn deletes groups sequentially and lets the first error propagate. Already-deleted groups are then lost from the response. Add a test where the second pruneCursorThreads call rejects. Assert that the first group was fully processed and that the server function rejects. This locks the current partial-deletion behavior and prevents silent regressions.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Guard the empty-selection case.

If pendingDelete is an empty array, open becomes true, the title reads "Delete Cursor workspaces?", and the description reads "delete every thread from 0 selected Cursor workspaces". Confirming then calls deleteCursorWorkspacesFn with workspaceKeys: [], which the min(1) validator rejects. Treat an empty array as no pending deletion.

🐛 Proposed fix
 const getWorkspaceDeleteDescription = (workspaces: CursorWorkspaceGroup[] | null) => {
-    if (!workspaces) {
+    if (!workspaces || workspaces.length === 0) {
         return '';
     }

Apply the matching guard where the dialog opens:

-                open={pendingDelete !== null}
+                open={pendingDelete !== null && pendingDelete.length > 0}

Bun SQLite Database inTransaction property API

💡 Result:

In Bun's bun:sqlite module, the Database class provides an inTransaction property to check the current transaction state [1][2]. The inTransaction property is a getter that returns a boolean value [2]: - true: The database is currently inside a transaction [2]. - false: The database is not currently in a transaction [2]. You can access it directly on your Database instance [2]: ts import { Database } from "bun:sqlite"; const db = Database.open(":memory:"); db.run("BEGIN"); console.log(db.inTransaction); // => true db.run("COMMIT"); console.log(db.inTransaction); // => false While inTransaction allows you to check the status, Bun also provides the db.transaction() method [3][4] to manage transactions programmatically. This method wraps a function such that it automatically executes within a transaction (using BEGIN and COMMIT or ROLLBACK on errors) [3][5]. If you call a function wrapped in db.transaction() while already inside another transaction, Bun automatically handles this using savepoints [5][6].

🌐 Web query:

SQLite transaction state after RAISE(ABORT) and ON CONFLICT ROLLBACK semantics sqlite3_get_autocommit

💡 Result:

In SQLite, the RAISE(ABORT,...) function and the ON CONFLICT ROLLBACK algorithm have distinct impacts on the transaction state. RAISE(ABORT,...) and ON CONFLICT ABORT: When RAISE(ABORT,...) is invoked within a trigger [1] or when an ABORT conflict resolution occurs [2], SQLite terminates the current SQL statement with an SQLITE_CONSTRAINT error [1]. Any changes made by that specific statement are backed out, but changes made by prior statements within the same transaction are preserved [2]. The transaction remains active [2]. ON CONFLICT ROLLBACK: When an ON CONFLICT ROLLBACK event occurs (e.g., due to a constraint violation in a table with that conflict resolution specified) [2], or if RAISE(ROLLBACK,...) is called in a trigger [1], the current SQL statement is aborted, and the entire transaction is rolled back [2]. If no explicit transaction was active, this behaves the same as an ABORT [3][2]. Checking Transaction State: Because certain errors (including those that trigger an automatic rollback) can leave a connection in a state where the transaction has been terminated, the C-language interface sqlite3_get_autocommit is the authoritative way to determine the current status [4][5]. - If sqlite3_get_autocommit returns non-zero, the connection is in autocommit mode (no transaction is active) [5]. - If it returns zero, the connection is within an explicit transaction [5]. If a statement causes a transaction to be rolled back automatically, sqlite3_get_autocommit will return non-zero, indicating that the transaction state has changed [4][5]. If the transaction remains active, it will continue to return zero [4]. Applications should use this interface to verify if they need to issue an explicit ROLLBACK or if the transaction has already been closed by the engine [4].

Citations:


Track the transaction state before rollback. If SQLite has already rolled back the transaction, open remains true and the subsequent ROLLBACK fails with “no transaction is active.” Check db.inTransaction before issuing ROLLBACK, and log any rollback failure.

Do not retry the writable callback on the same connection.

deleteThreadIds changes connection state with ATTACH DATABASE codex_history and DETACH DATABASE codex_history. If DETACH raises a retryable database is locked error, withWritableDb retries deleteThreadIds while the database remains attached. The retry then fails with database codex_history is already in use.

Move retry handling out of withWritableDb. Restore attachment state before each retry, or open a fresh connection for each retry.

Deduplicate spawn edges across chunks.

readBrowseRelations runs once per chunk. The predicate matches an edge when the parent or the child is in the chunk. If the parent falls in one chunk and the child falls in another chunk, both queries return the same edge row. The code then pushes the edge into parentRelations.childEdges twice. The result is duplicated child edges in ThreadRelations, which then reach the transcript renderer and the export manifest.

The previous readThreadHierarchyEdges implementation guarded against this with a seenEdges set. Restore that guard.

🐛 Proposed fix
 const readBrowseRelations = (
     db: Database,
     threadIdChunk: string[],
     relationsByThreadId: Map<string, ThreadRelations>,
+    seenEdgeKeys: Set<string>,

+        }
+        seenEdgeKeys.add(edgeKey);

Reuse filesystem indexes across the batch.

readSessionIndexEntries caches parsed records, but each thread still stats session_index.jsonl and rebuilds the name map. Missing IDs also rescan the cached entries and recompute the session-file index fingerprint. Load the session-index names and session-file map once in getThreadBrowseDataBatch, then pass the results to buildThreadBrowseData and the fallback lookup.

Collapse the three identical error conversions.

The stat, copy, and second stat calls each repeat the same catch block that builds a CodexRolloutSourceError. Extract one helper and reuse it.

The export code creates temporary paths with the cline_ prefix. This filter only matches names that start with fallbackProjectName, so leaked artifacts pass the test.

Make focused export submission cancellation-safe.

submitExport awaits loadEvidence() and then calls downloadTextFile without checking whether the dialog was closed. If requestEvidenceExport is still pending when the user closes the dialog, its continuation can trigger a download after cancellation. If preparation fails, loadEvidence() returns null and Lines 271-273 leave the status at 'preparing'.

Invalidate the submission on close and check a submission token before downloading. Set downloadState to 'failed' when preparation returns no result.

Review Findings

SEVERITY: HIGH

1. Unbounded rollout mutation retry

  • File: src/lib/codex-rollout-snapshot.ts
  • Evidence: MAX_ROLLOUT_EXPORT_ATTEMPTS = 2 is defined but the mutation loop in codex-browser-export.ts:withStableRolloutSnapshot can continue indefinitely if attempt < MAX_ROLLOUT_EXPORT_ATTEMPTS is always true
  • Impact: A continuously-mutating rollout file (e.g., active Codex writing) could loop 2 times max, but the error messaging and attempt tracking suggest this is meant as a bounded retry. However, the loop structure for (let attempt = 1; attempt <= MAX_ROLLOUT_EXPORT_ATTEMPTS; attempt += 1) is correct and bounded. The actual issue is there's no exponential backoff or detection of actively-writing files.
  • Fix: Add exponential backoff delays between retry attempts and/or detect if the file is actively being written (check if size is still changing rapidly) to fail fast instead of retrying.

2. Partial transaction rollback in Cursor workspace bucket deletion

  • File: src/lib/cursor-recovery.ts:656-691
  • Evidence: pruneWorkspaceBuckets collects snapshots of all affected buckets, then updates them sequentially. If an update fails mid-sequence, it attempts to rollback only the already updated paths. But the rollback itself can fail per-database, throwing an AggregateError that hides partial rollback success.
  • Impact: A failure during bucket updates (e.g., database locked) followed by partial rollback failures leaves some buckets restored and others not, with unclear state reporting to the user.
  • Fix: Track rollback status per-database separately and report which buckets were successfully rolled back vs failed. Consider a two-phase prepare/commit pattern or warn users that concurrent Cursor usage during deletion is unsafe.

3. Directory deletion path validation race condition

  • File: src/lib/cursor-recovery.ts:729-762
  • Evidence: deleteCursorWorkspaceBuckets validates bucket paths using realpath() to get canonical paths, then calls rm(). Between validation and deletion, a symlink attack could redirect the validated path.
  • Impact: An attacker with local filesystem access could replace a validated bucket directory with a symlink to an unrelated directory between validation and deletion, causing data loss outside the intended Cursor storage.
  • Fix: Open a file descriptor to the validated directory before validation completes, then use rm() with the FD or verify the path hasn't changed immediately before rm(). Alternatively, re-validate the canonical path immediately before rm().

4. Missing AbortSignal propagation in batch export

  • File: src/lib/codex-browser-export.ts:411-489
  • Evidence: renderCodexThreadsDownload has no signal parameter and doesn't propagate cancellation to withStableRolloutSnapshot or renderCodexBatchEntry. The single-thread export path passes signal in download.ts, but batch exports cannot be cancelled mid-flight.
  • Impact: Large batch exports (dozens of threads) cannot be cancelled by the user once started, forcing them to wait minutes or reload the page.
  • Fix: Thread AbortSignal through renderCodexThreadsDownload, renderCodexBatchEntry, and withStableRolloutSnapshot. Check signal between batch entries and throw DownloadCancelledError if aborted.

SEVERITY: MEDIUM

5. Antigravity keychain secret in memory without zeroing

  • File: src/lib/antigravity-keychain.ts:174-183
  • Evidence: withAntigravityDecryptionCapability reads the keychain secret into a string and passes it to the action callback. JavaScript strings are immutable and cannot be zeroed after use, leaving the secret in memory until GC.
  • Impact: A memory dump or heap inspection during or after decryption could expose the keychain secret, which decrypts all Antigravity artifacts.
  • Fix: Document that the secret remains in memory until GC and consider using a Buffer that can be explicitly zeroed with .fill(0) after use. For full security, recommend users keep Antigravity encrypted artifacts in secure storage and avoid running Spiracha in untrusted environments.

6. Cline task deletion concurrency bottleneck

  • File: src/lib/cline-db.ts:387-415
  • Evidence: deleteClineTask is wrapped in clineDeleteLimiter(1), forcing all deletions to run sequentially even when deleting multiple tasks.
  • Impact: Bulk deletion of 50+ Cline tasks takes significantly longer than necessary (seconds per task instead of parallel deletion).
  • Fix: Remove the limiter or increase concurrency to 4-8. The actual SQLite write (deleting from sessions.db) is already safe via readwrite: true mode, and filesystem rm() calls are independent per task.

7. Codex session file fingerprint collision

  • File: src/lib/codex-browser-db.ts:1101-1109
  • Evidence: getSessionFileIndexFingerprint combines size:mtimeMs from session_index.jsonl and the sessions directory. If two scans happen within the same millisecond and file sizes are unchanged, the fingerprint collides even if file contents changed.
  • Impact: Stale session file mappings could be returned after rapid Codex writes, causing exports to use outdated rollout paths.
  • Fix: Include inode or a content hash in the fingerprint, or add a monotonic scan counter to force cache invalidation on repeated scans within the same millisecond.

8. Cursor transcript directory path validation insufficient

  • File: src/lib/cursor-recovery.ts:630-649
  • Evidence: pruneCursorThreads validates transcript directories by checking the directory structure and relative path from a canonical projects directory. However, it uses path.basename(resolvedDir) and string comparisons instead of verifying the canonical path is strictly within the projects directory subtree.
  • Impact: A carefully crafted transcript directory name with path traversal sequences (e.g., ../../sensitive/data/agent-transcripts/<composerId>) might bypass validation if symlinks or hardlinks create unexpected canonical paths.
  • Fix: After computing canonicalRelativePath, verify it does not contain .. components and that the canonical directory is strictly under canonicalProjectsDir using canonicalDir.startsWith(canonicalProjectsDir + path.sep).

SEVERITY: LOW

9. Export manifest schema version not enforced

  • File: src/lib/codex-browser-export.ts:49-67
  • Evidence: BATCH_MANIFEST_SCHEMA_VERSION = 1 is written to the manifest but never validated on read. Future schema changes could break parsing without detection.
  • Impact: If manifest format changes in a future version, older Spiracha versions reading new manifests will fail silently or parse incorrectly.
  • Fix: Add a manifest reader function that validates schemaVersion and throws a clear error if the version is unsupported. Document the manifest format and versioning strategy.

10. Missing nullish coalescing in Cline timestamp parsing

  • File: src/lib/cline-db.ts:70-82
  • Evidence: timestampFromJson checks numeric !== null and !text separately, but does not handle undefined consistently with null. Given that JSON parsing can produce both, this could miss valid timestamps.
  • Impact: Cline sessions with undefined timestamps (from malformed JSON) may show incorrect activity times in the UI.
  • Fix: Use ?? null coalescing consistently and document that undefined is treated as null for timestamps.

11. Codex thread browse DB query retries without logging

  • File: src/lib/codex-browser-db.ts:470-530
  • Evidence: withReadonlyDb wraps queries in runWithSqliteRetry, which silently retries on SQLITE_BUSY. For long-running Codex writes, this could retry many times without visibility to the user or logs.
  • Impact: UI hangs or slow responses when Codex is actively writing threads, with no indication to the user that the database is busy.
  • Fix: Add optional retry count and delay logging to runWithSqliteRetry for diagnostic purposes, or surface retry counts in the UI for long-running queries.

12. OpenCode session directory grouping assumes 'global' project

  • File: Review description mentions "OpenCode: resolved session.directory grouping for sessions under the global project."
  • Evidence: Without seeing the OpenCode discovery code, this suggests a hardcoded assumption about the 'global' project key.
  • Impact: If OpenCode adds non-global projects or changes the default project name, sessions may not group correctly.
  • Fix: Make project detection dynamic and document the assumption that OpenCode uses a 'global' project key for ungrouped sessions.

13. Antigravity history cache unbounded memory growth

  • File: src/lib/antigravity-transcript-history.ts:27-30
  • Evidence: MAX_HISTORY_CACHE_BYTES = 32MB and MAX_HISTORY_CACHE_ENTRIES = 32 are enforced in cacheHistory, but historyCacheBytes is never decremented if cache eviction fails or if cache entries are mutated externally.
  • Impact: Repeated history reads with eviction failures could grow historyCacheBytes beyond the limit without bound, causing memory pressure.
  • Fix: Add defensive bounds checking before cache writes and log warnings if historyCacheBytes exceeds the limit. Consider resetting the cache entirely if corruption is detected.

14. Cursor bubble count queries use LIKE without ESCAPE sanity check

  • File: src/lib/cursor-db.ts:456 (read in context from recovery.ts usage)
  • Evidence: buildCursorBubbleKeyLikePattern is called to build LIKE patterns with ESCAPE '\\', but there's no validation that the composerId doesn't contain backslashes or other LIKE metacharacters before pattern construction.
  • Impact: If a malformed composerId contains % or _, bubble counts could be inflated or queries could be very slow.
  • Fix: Add validation in assertSafeCursorComposerId to reject IDs with LIKE metacharacters, or escape them explicitly before building the pattern.

15. Codex export workspace cleanup failure swallows errors

  • File: src/lib/codex-browser-export.ts:131-140
  • Evidence: cleanupExportWorkspace catches and logs errors but does not propagate them. If cleanup consistently fails (e.g., permissions issue), temporary export directories accumulate in os.tmpdir().
  • Impact: Disk space leak over time if exports fail repeatedly and cleanup is silently broken.
  • Fix: Track cleanup failures and surface a warning to the user after N consecutive failures. Consider a startup check to clean stale export directories.

Findings

1. [High] Batch export is not resilient to a single malformed thread row — defeats the partial-failure design of #20

File: src/lib/codex-browser-export.ts (line ~474), src/lib/codex-browser-db.ts (getThreadBrowseDataBatch, readThreadBrowseRows)
Evidence: renderCodexThreadsDownload calls getThreadBrowseDataBatch(input.dbPath, threadIds) before any per-thread try/catch exists. Inside the DB layer, readThreadBrowseRows decodes every row via decodeThreadTableRow/requiredString(...), which throw CodexDbCompatibilityError on any malformed field (e.g. a bad created_at, cwd, rollout_path in one row). That decode runs for the whole chunk inside the shared withSqliteTransaction, so one corrupt row aborts the entire batch.
Impact: Issue #20's requirement — "handle partial failures gracefully with manifest files instead of failing the whole archive" — is only enforced for errors raised inside renderCodexBatchEntry. Any per-row decode/compat failure raised during the batch read happens before the manifest loop, so all N threads fail instead of N-1 being exported with one manifest "unstable/unreadable" entry. This works for missing threads but not for malformed threads.
Fix: Make getThreadBrowseDataBatch isolate per-thread build failures (wrap each buildThreadBrowseData(...) call in its own try/catch and return a status:'unstable' entry with the error), or hoist the batch into the per-entry manifest loop so a decode failure maps to a manifest entry rather than aborting.

2. [High] Destructive Cursor deletion has no rollback path for the post-commit filesystem phase

File: src/lib/cursor-recovery.ts (pruneCursorThreads, deleteCursorWorkspaceBuckets, deleteCursorWorkspaceHistory), src/ui/lib/cursor-server.ts (deleteCursorWorkspaceGroup)
Evidence: deleteCursorWorkspaceGroup runs three irreversible stages sequentially:

  1. pruneCursorThreads(...) — commits bucket DB mutations and the global DB transaction, then pruneTranscriptDirs (rm on transcript dirs),
  2. deleteCursorWorkspaceBuckets(group)rm(bucketRoot, {recursive}),
  3. deleteCursorWorkspaceHistory(group)rm on History entries.

There is no compensation between them: once the global DB transaction commits inside pruneGlobalThreads, a throw in pruneTranscriptDirs or in step 2/3 leaves torn state (DB rows gone, physical dirs still present, or some buckets removed and others not). Contrast with the careful bucketMutation.rollback() that only covers the bucket-DB phase.
Impact: A transient ENOTEMPTY/EACCES/EIO during the later filesystem phase silently produces a partially-deleted workspace with no recovery signal. deleteCursorWorkspacesFn also loops workspaces with no cross-workspace rollback, so a bulk delete can leave an earlier workspace fully destroyed when a later one fails.
Fix: Collect physical paths first, validate all up front (already done), and structure the destructive sequence so that any failure before the final irreversible step reports an accurate "needs retry" state; for the bulk endpoint, continue-on-error and return per-workspace status rather than aborting mid-loop, or pre-compute all failure-prone filesystem ops that can be validated before any commit.

3. [High] Cursor workspace-history deletion is too coarse: one matching file deletes the whole resource's history

File: src/lib/cursor-recovery.ts (deleteCursorWorkspaceHistory, isCursorHistoryEntryForWorkspace)
Evidence: The loop reads each History/*/entries.json, and if data.resource (a single file URI) is under any of group.folders, it rm(entryPath, {recursive:true}) — deleting the entire history directory for that resource. Cursor's history is keyed per resource file and holds revisions of that file; the check tests only whether the file's path is inside the workspace folder, not whether any history revisions belong to a different workspace.
Impact: A resource path that is shared or reached via a symlink/mount from another workspace (or a file edited in a second workspace that happens to resolve under the deleted folder) loses all of its version history for the sibling project. The reviewer's own goal — "removes associated file-history safely without affecting sibling projects" — is violated for any overlapping resource.
Fix: Scope history removal by matching the workspace's owning data (e.g. compare against the workspace identifier stored in the history entry metadata, not just resource path containment), or at minimum require that the entry's resource is exclusively within the workspace's own root rather than merely under one folder.

4. [Medium] immutable=1 WAL reads are not a consistent snapshot under concurrent Codex/Cursor writers (#12)

File: src/lib/codex-browser-db.ts (line 267), src/lib/cursor-db.ts (getCursorReadonlyDbUri, line 50-59)
Evidence: Both DBs are WAL-mode and are read with immutable=1 (chosen so reads work after a clean shutdown removes the -wal/-shm sidecars). With immutable=1, SQLite ignores the WAL entirely and reads only the last checkpointed main DB. Meanwhile readBrowseFilesystemData (session files, session index) runs outside the SQLite BEGIN DEFERRED transaction and is only reconciled after the snapshot commits (comment at buildThreadBrowseData).
Impact: Under an active writer, a browse read can see DB rows that are older (uncheckpointed rows invisible) than the matching filesystem session/rollout file, or a mid-checkpoint torn page; the assembled thread then mixes two snapshots taken at different times. This is precisely the consistency question #12 asked, and the immutable tradeoff is not compensated by any re-read or write-lock.
Fix: Document and/or gate: when WAL sidecars are present (writer active), read with a real mode=ro replay (or use BEGIN snapshot on the hot DB) and run the filesystem snapshot inside the same logical read window; otherwise keep immutable=1 only for the cold case.

5. [Medium] Rollout "stable snapshot" verifies stat identity, not content — can render a torn copy

File: src/lib/codex-rollout-snapshot.ts (copyStableCodexRollout, isSameIdentity)
Evidence: Stability is decided by inode/ctimeMs/mtimeMs/sizeBytes equality between the pre-copy and post-copy stat. Bun.write(snapshot, Bun.file(source)) streams the file; a concurrent Codex process that rewrites the rollout and restores an identical size/inode (or where mtime/ctime are batched at the same granularity) passes the check even if the snapshot captured a partial/interleaved write.
Impact: With MAX_ROLLOUT_EXPORT_ATTEMPTS = 2, only one retry exists, and the rendered output is never content-checked. A persistent-but-subtle mutation produces either a mutation failure on a readable file (fail-closed, acceptable) or — worse — a snapshot that passes identity while containing a torn JSONL line that renders truncated data.
Fix: Add a cheap content check (e.g. compare a line-count/JSON validity probe, or a read-once hash of source vs snapshot) as part of the stability comparison, and/or make the failure diagnostic state explicitly that a content mismatch (not a mutation) was detected.

6. [Medium] Antigravity keychain: removing process-global caching re-spawns security per encrypted conversation with no scoped memoization (#29)

File: src/lib/antigravity-keychain.ts (withAntigravityDecryptionCapability, readAntigravityKeychainSecret), src/ui/lib/antigravity-server.ts (acquireAntigravityDecryptionCapability)
Evidence: acquireAntigravityDecryptionCapability()withAntigravityDecryptionCapabilityexecFile('security', ['find-generic-password', '-w'], {timeout:10000}) runs on every invocation. loadAntigravityConversationDetail/loadAntigravityConversationExport call it once per conversation render, and there is no request/session-scoped cache of either the secret or the derived key.
Impact: Rendering a page that processes several encrypted conversations spawns one security subprocess (with a 10s timeout and no maxBuffer) and re-runs PBKDF2 for each — multiplied under parallel/concurrent loads. The macOS Keychain can rate-limit or return auth errors under bursty access, and the timeout means a slow/unlocked daemon throws AntigravityDecryptionCapabilityError after 10s per request. The removal of global state is correct security-wise, but the (safe) alternative — per-request memoization keyed to the request lifetime — was dropped entirely.
Fix: Memoize the derived capability (key is derived from the secret, not the secret) per request/session scope with explicit eviction at request end, so concurrent conversations share one security read without process-global persistence.

7. [Medium] Cline legacy-storage removal has no migration path or diagnostic for older-version users

File: src/lib/cline-db.ts, src/lib/cline-db.test.ts (line ~230 "should ignore the removed VS Code task-history format")
Evidence: Discovery now reads only sessions/<id>/<id>.json and the test explicitly asserts that state/taskHistory.json and ui_messages.json are intentionally ignored. There is no compatibility branch and no warning if a ~/.cline/data/sessions directory is empty/nonexistent while legacy files are detected.
Impact: Users still on a Cline version that stored history only in VS Code globalStorage (state/taskHistory.json, ui_messages.json) silently see zero sessions — a data-visibility regression with no migration hint or log entry, as the reviewer specifically asked to guard against.
Fix: On empty/modern-layout discovery, detect the absence of a modern sessions directory combined with presence of legacy files and surface a one-time user-facing notice (and/or attempt a read-only legacy fallback) rather than silently returning an empty list.

8. [Medium] Cline session fallback cwd defaults to the session directory, so workspace grouping can mis-scope

File: src/lib/cline-db.ts (parseSessionEntry)
Evidence: const cwd = header.cwd ?? sessionDir; — when metadata lacks workspace_root/cwd, the workspace key is set to the sessions/<id> directory path rather than the real project root. Since parseSessionHeader returns workspaceSource:'session_directory' only when cwd is absent, the grouping/collection logic may attribute the thread to the wrong workspace.
Impact: Threads without machine-readable cwd metadata are grouped under the storage session path (not the actual project), so cwd-scoped collection and workspace display can be wrong — undercutting the "display properly across workspaces" goal for older/lean session headers.
Fix: Recognize the ambiguous case explicitly (e.g. mark the workspace as unresolved to the UI) instead of silently claiming session_directory as the cwd, or fall back to an existing workspace-label resolution when available.

9. [Low] renderCodexBatchEntry's broad catch masks programming errors as per-thread "unreadable" skips

File: src/lib/codex-browser-export.ts (renderCodexBatchEntry catch, getBatchFailure)
Evidence: The catch only re-throws for isArchiveWideFailure(error) (checks error.code / error.cause.code against EACCES/EIO/ENOSPC/... or CodexDbCompatibilityError); everything else — including TypeError, null-deref, render bugs — is converted to a manifest entry with status:'unreadable'. getBatchFailure only specially handles CodexThreadNotFoundError/CodexRolloutSourceError; all other errors become generic "unreadable".
Impact: A genuine regression in the render path is silently swallowed and reported to the user as "thread could not be read," so the archive "succeeds" with a missing thread and no stack trace surfaces. This masks the exact class of bug a reviewer is asked to find, and isArchiveWideFailure misses nested causes (e.g. AggregateError.causes).
Fix: Distinguish known per-thread failure types (not-found, unreadable, mutation-exhausted) from unexpected errors — rethrow unexpected ones (or attach them to the manifest with the original stack) instead of folding them into "unreadable".

10. [Low] Download polling treats permanent server failures as "not ready yet" and burns the full retry budget

File: src/ui/lib/download.ts (probeDownloadUrl, waitForDownloadUrlAvailability)
Evidence: probeDownloadUrl returns false for any non-ready status (including real 404/500 from a failed server-side export) and waitForDownloadUrlAvailability keeps sleeping/retrying up to DEFAULT_DOWNLOAD_ATTEMPTS = 6 at 250ms, then throws a generic Download file was not available....
Impact: A permanently-failed export neither cancels the poll nor surfaces a specific error — the user waits through the full retry budget and sees only a timeout message, indistinguishable from "still preparing." The AbortSignal does correctly abort the in-flight HEAD fetch, but there's no fast-fail on a definitive error status.
Fix: On a 4xx/5xx that indicates the server rejected the export (404/410/500), stop retrying and surface the actual status/error through onStateChange('failed') rather than returning false and re-polling.

11. [Low] No per-directory error aggregation in transcript/workspace filesystem pruning

File: src/lib/cursor-recovery.ts (pruneTranscriptDirs, deleteCursorWorkspaceHistory)
Evidence: pruneTranscriptDirs fires mapWithConcurrency(..., rm) and only records transcriptDirsRemoved = transcriptDirs.length optimistically; if one rm throws mid-batch, the remaining dirs are left in place and no partial count is returned. Same pattern in the bucket/history loops, which throw on first error and leave earlier removals applied.
Impact: On failure the reported transcriptDirsRemoved can overstate reality, and retry cannot know what still needs removing, complicating recovery for a destructive op that already carries no rollback (finding #2).
Fix: Collect per-item results (success/failure) and return an accurate partial count plus the list of remaining paths so a retry is idempotent.

Here are the findings from reviewing the requested focus areas, ordered by severity:

1. Severity: High
Path: src/lib/cline-db.ts
Evidence: listClineSessionEntries exclusively reads from path.join(dataDir, 'sessions') (lines 213-214) and deleteClineTask only handles the sessions/ directory. There is no detection logic for legacy VS Code JSON files (taskHistory.json, ui_messages.json).
Impact: Dropping legacy file parsing without a fallback or detection mechanism silently hides tasks for users who haven't updated Cline or migrated their storage layout. They will experience a data visibility regression with no migration warning.
Suggested Fix: Add a check for taskHistory.json or ui_messages.json in dataDir. If they exist and sessions/ is empty or missing, either restore legacy parsing as a fallback or throw a descriptive error/emit a clear UI warning prompting the user to migrate their Cline data.

2. Severity: Medium
Path: src/lib/antigravity-keychain.ts
Evidence: readAntigravityKeychainSecret spawns execFileAsync('security', ...) on every invocation (lines 191-196) without promise deduplication or request-scoped batching.
Impact: Concurrent decryption requests (e.g., when parsing multiple Antigravity transcripts in parallel during a bulk export or collection) will spawn multiple security processes simultaneously. If the keychain is locked, the OS will spam the user with multiple concurrent password prompts.
Suggested Fix: Introduce promise deduplication for readAntigravityKeychainSecret. Store the pending promise in a module-scoped variable so concurrent callers await the same active security process, and clear the variable once it resolves or rejects.

Findings

1. [Critical] SQLite Transaction Violation During Codex Thread Deletion with Attached History Database

  • File / Path: src/lib/codex-browser-db.ts:1699-1721
  • Evidence: deleteThreadIds executes withSqliteTransaction(db, (transactionDb) => { ... }), which starts a transaction via BEGIN DEFERRED (src/lib/codex-browser-db.ts:550-568). Inside the callback, getExistingTableNames(transactionDb) and getThreadDeleteTargets(transactionDb, ...) run SELECT queries, promoting the connection to an active transaction. Then, if thread_history_1.sqlite exists on disk, line 1709 executes:
    transactionDb.query('ATTACH DATABASE ? AS codex_history').run(historyDbPath);
  • Impact: SQLite forbids attaching databases inside an active transaction (cannot ATTACH database within transaction). In any environment where Codex history exists (thread_history_1.sqlite), single-thread, multi-thread, and project deletions will unconditionally throw an error and rollback, breaking Codex thread deletions.
  • Suggested Fix: Move the ATTACH DATABASE statement outside and before withSqliteTransaction(db, ...), and ensure DETACH DATABASE codex_history runs in a finally block after the transaction commits or rolls back:
    const historyDbPath = resolveCodexHistoryDbPath(dbPath);
    const historyAttached = hasRegularFile(historyDbPath);
    if (historyAttached) {
        db.query('ATTACH DATABASE ? AS codex_history').run(historyDbPath);
    }
    try {
        withSqliteTransaction(db, (transactionDb) => {
            // perform deletions across main and codex_history tables...
        });
    } finally {
        if (historyAttached) {
            try {
                db.query('DETACH DATABASE codex_history').run();
            } catch (error) { ... }
        }
    }

2. [High] Unscoped Keychain Subprocess Flooding in Batch Antigravity Exports

  • File / Path: src/ui/lib/antigravity-server.ts:51-54, 200, 317-350
  • Evidence: In src/ui/lib/antigravity-server.ts, acquireAntigravityDecryptionCapability immediately extracts the capability:
    const acquireAntigravityDecryptionCapability = async () => {
        const { withAntigravityDecryptionCapability } = await import('@spiracha/lib/antigravity-keychain');
        return withAntigravityDecryptionCapability((capability) => capability);
    };
    In exportAntigravityConversations (lines 317–350), Promise.all executes loadAntigravityConversationExport concurrently for all selected conversations. Inside loadAntigravityConversationExport (line 200), acquireAntigravityDecryptionCapability() is invoked individually for each encrypted conversation, spawning N parallel security find-generic-password CLI subprocesses without sharing state.
  • Impact: Bypasses the intended request-scoped keychain capability pattern (Issue Replace process-global Antigravity keychain state with scoped decryption handling #29). Concurrently querying the macOS Keychain with multiple spawned security subprocesses causes process contention, timeouts, and can trigger redundant OS authorization prompts to the user.
  • Suggested Fix: Acquire the AntigravityDecryptionCapability once at the request level in exportAntigravityConversations, and pass decryptionCapability into each loadAntigravityConversationExport call:
    const hasEncrypted = selectedConversations.some(hasEncryptedAntigravityConversation);
    const decryptionCapability = hasEncrypted ? await acquireAntigravityDecryptionCapability() : null;
    const entries = await Promise.all(
        selectedConversations.map(async (loadedConversation) => {
            const result = await loadAntigravityConversationExport(
                loadedConversation.conversationId,
                renderOptions,
                loadedConversation,
                decryptionCapability,
            );
            ...
        })
    );

3. [Medium] Missing Global Header Table Backup During Cursor Thread Pruning

  • File / Path: src/lib/cursor-recovery.ts:96-110, 451-466, 530
  • Evidence: pruneCursorThreads (line 530) invokes backupPrunedThreads(globalDbPath, [...composerIds]). backupPrunedThreads backs up disk bubbles, composerData:<id> from cursorDiskKV, and matching rows in SQLite table composerHeaders. However, pruneGlobalThreads -> removeThreadHeaders (lines 451–466) also modifies ItemTable key COMPOSER_HEADERS_KEY (composer.composerHeaders).
  • Impact: If Cursor thread pruning fails mid-stream or needs manual restoration, the backup JSON file lacks the ItemTable composer.composerHeaders state, preventing full header restoration for workspaces that store headers in ItemTable.
  • Suggested Fix: Include COMPOSER_HEADERS_KEY from ItemTable inside backupPrunedThreads payload, or invoke await backupComposerHeaders(globalDbPath) alongside backupPrunedThreads.

4. [Medium] Disconnected Progress Lifecycle Reporting in Full/Batch UI Exports

  • File / Path: src/ui/components/export-dialog.tsx:198, 281-296 and src/ui/routes/threads.$threadId.tsx:746 (and sibling route handlers)
  • Evidence: ExportDialog includes a DownloadStateMessage component reflecting downloadState ('preparing' | 'ready' | 'downloading' | 'cancelled' | 'failed'). In submitExport, line 289 sets setDownloadState('preparing'). When mode !== 'focused', onExport is invoked as a bare callback ({ ...options, zipArchive }) => void. The route mutations call downloadUrlFileWithCancellation(downloadCancellation, download.fileName, download.downloadUrl) without forwarding an onStateChange callback.
  • Impact: Coarse-grained export progress (Issue Add progress and cancellation support for long-running exports #23) never transitions past 'preparing' ("Preparing export...") during export polling for full and batch downloads in the UI dialog until the dialog is closed or errors.
  • Suggested Fix: Pass onStateChange: setDownloadState through onExport or expose a shared download state hook so downloadUrlFileWithCancellation can update the dialog's progress indicators through 'ready' and 'downloading'.

5. [Low] Missing Cleanup for Interrupted Streams in Antigravity JSONL Reader

  • File / Path: src/lib/antigravity-transcript-history.ts:217-251
  • Evidence: readAntigravityJsonlFile acquires a stream reader via Bun.file(filePath).stream().getReader(). The while (true) read loop is not wrapped in a try...finally block with reader.cancel().
  • Impact: If JSON parsing, line processing, or consumer memory limits throw an unhandled error during stream reads, the reader is not explicitly canceled, keeping the stream resource open until garbage collected.
  • Suggested Fix: Wrap the reader.read() loop in try...finally and call await reader.cancel() if exiting prematurely before done === true.

Findings (ordered by severity)

HIGH — Cline legacy layout regression (silent data loss of history)
src/lib/cline-db.ts:212-224, :527-541 only read ~/.cline/data/sessions/<id>/<id>.json. taskHistory.json/ui_messages.json are no longer consulted anywhere (only a test at cline-db.test.ts:235 references state/taskHistory.json). Users whose Cline storage is the older state//taskHistory.json layout get an empty workspace list with no warning or migration path. This directly violates the reviewer's stated concern. Fix: detect the legacy layout and either read it or emit a clear "unsupported legacy layout" diagnostic instead of silently returning zero tasks.

HIGH — One bad thread aborts the entire Codex batch export (no manifest)
src/lib/codex-browser-db.ts:2164-2245 getThreadBrowseDataBatch runs decodeThreadRow (:544-545) inside the single transaction; a single present-but-malformed thread row throws CodexDbCompatibilityError, which propagates out of renderCodexThreadsDownload (codex-browser-export.ts:474) before the per-thread manifest loop (:506-508). Result: a single corrupt thread kills a whole multi-select export with no spiracha-manifest.json, contradicting Issue #20. Fix: isolate decode errors per thread (return status:'missing'/error) so the manifest still enumerates the rest.

MEDIUM — pruneCursorThreads trusts caller-supplied transcript dirs
src/lib/cursor-recovery.ts:489-505 only validates thread.transcriptDirs, and :648-654 pruneTranscriptDirs removes exactly those. If the UI passes summaries built without transcript dirs (empty array), the safety check is skipped entirely and the on-disk ~/.cursor/projects/*/agent-transcripts/<id> directories are never deleted, while the global bubbles/headers are removed — leaving orphaned transcripts and an inconsistent state. Fix: re-derive dirs inside pruneCursorThreads via findCursorTranscriptDirsForComposerIds rather than trusting input.

MEDIUM — createDownloadCancellation stays permanently cancelled
src/ui/lib/download.ts:130-142: after cancel() sets cancellationRequested=true, every subsequent begin() immediately aborts the new signal. Unless the UI also dispatches the reset event, all later downloads in that component are instantly cancelled. Fix: clear cancellationRequested at the start of begin() (or on finish()), so cancel is edge-triggered, not level-triggered.

MEDIUM — Blocking SQLite retry sleeps stall the event loop
src/lib/sqlite-retry.ts:12-18 uses Atomics.wait (synchronous, blocks the Bun main thread) for up to 250ms/retry, invoked from withCursorReadonlyDb/withCursorWriteTransaction (cursor-db.ts:79-123). Under Cursor-lock contention, concurrent browse/read requests serialize and the whole UI server stalls — a real availability concern given Issues #12/#13's concurrency emphasis. Fix: use async Bun.sleep/sleepSync off the main thread, or shorten/eliminate blocking waits on the read path.

MEDIUM — Antigravity keychain secret re-read per request
src/lib/antigravity-keychain.ts:186-202, :208-218: withAntigravityDecryptionCapability calls readAntigravityKeychainSecret (security find-generic-password) on every request. A batch export of N conversations issues N concurrent OS-keychain reads, risking repeated prompts / serial waits — exactly the concern flagged for "concurrent decryption requests." Fix: memoize the in-flight secret promise per process (short TTL) so a burst reads the keychain once.

MEDIUM — deleteCursorWorkspaceBuckets leaves global data (deletion appears incomplete)
src/lib/cursor-recovery.ts:656-699 removes workspaceStorage/<bucketId>, but thread content lives in the global cursorDiskKV/composerHeaders/ItemTable, not the bucket. It does not prune those global rows, so discovery re-enumerates the threads and they reappear (with bubbles intact). Either this should also delete the bucket's global composer references, or it should be documented as "remove local workspace copy, not conversations."

LOW — TOCTOU in deleteCursorWorkspaceBuckets
src/lib/cursor-recovery.ts:675-691 validates via realpath(bucketRoot) but then rm(bucketRoot.path, …) uses the non-canonical path. A symlink swapped in the window between check and rm could target a different directory. Fix: rm the realpath result (same as validated).

LOW — Codex cross-DB ATTACH delete is not crash-atomic
src/lib/codex-browser-db.ts:1705-1731 documents that an OS crash during WAL commit can leave codex_history.* rows orphaned relative to threads. Acceptable but should be called out in the isolation/durability docs (Issue #13).

LOW — In-memory zipSync for large exports
src/lib/ui-export-zip.ts:9,34-39 (and conversation-zip-export.ts:78 loading the whole zip into a Blob) read/zip the entire archive in memory synchronously. The 128 MB+ "large export" path (codex-browser-export.ts:63,286-288) will block the event loop and spike memory. Use streaming fflate Zip for large archives.

LOW — Download poll bound too short for large exports
src/ui/lib/download.ts:45-46,254 defaults to 6 × 250ms = 1.5s of HEAD polling. Server-rendered large zips can exceed that, causing spurious "file was not available after N attempts" failures. Make the bound configurable / raise it.

LOW — deleteClineTask doesn't clean legacy files
src/lib/cline-db.ts:543-565 removes sessions/<taskId> and db/sessions.db only; combined with the #1 regression, deleting a legacy-only task is effectively a no-op (returns not_found).

High

1. Cursor bubble key range collides with ':' in composerId

  • File/path: src/lib/cursor-id.ts:19-23
  • Evidence: getCursorBubbleKeyRange returns start = 'bubbleId:${composerId}:' and end = 'bubbleId:${composerId};'. isSafeCursorComposerId allows : in SAFE_CURSOR_COMPOSER_ID_PATTERN = /^[A-Za-z0-9][A-Za-z0-9._:-]{0,255}$/u.
  • Impact: Half-open range relies on ; being the next code point after :. If a composerId contains :, e.g. abc:def, the range bubbleId:abc:def:bubbleId:abc:def; does not correctly bound keys. Bubble count/delete queries in cursor-recovery.ts:283-298 and cursor-db.ts will miss keys or include keys from a different id. Destructive prune/delete becomes incomplete / over-inclusive.
  • Suggested fix: Disallow : in the safe id regex, or stop using a lexical range and use LIKE ? ESCAPE '\' with escaped id as done in buildCursorBubbleKeyLikePattern. If range kept, pick a delimiter guaranteed > any valid id character.

2. Cursor transcript-dir validation mixes canonical / non-canonical paths

  • File/path: src/lib/cursor-recovery.ts:485-504
  • Evidence: projectsDir = path.resolve(...), canonicalProjectsDir = await realpath(projectsDir).catch(...). For each transcriptDir:
    const resolvedDir = path.resolve(transcriptDir);
    const resolvedProjectsDir = path.dirname(path.dirname(path.dirname(resolvedDir)));
    const canonicalDir = await realpath(resolvedDir).catch(() => resolvedDir);
    const canonicalRelativePath = path.relative(canonicalProjectsDir, canonicalDir);
    Check uses resolvedProjectsDir !== projectsDir and canonicalRelativePath checks, but resolvedProjectsDir is not canonicalised.
  • Impact: Symlink in the projects tree can make resolvedProjectsDir equal to projectsDir while canonicalDir escapes the real projects root. The .. check on canonicalRelativePath can be bypassed, allowing unsafe rm -r of arbitrary paths in pruneTranscriptDirs src/lib/cursor-recovery.ts:648-654.
  • Suggested fix: Canonicalise both sides: compare await realpath(resolvedProjectsDir) with canonicalProjectsDir, and derive the relative path from canonical values only.

3. Export cancellation not propagated into rollout snapshot retry loop

  • File/path: src/lib/codex-browser-export.ts:166-209 withStableRolloutSnapshot
  • Evidence: Loop for (let attempt = 1; attempt <= MAX_ROLLOUT_EXPORT_ATTEMPTS; attempt += 1) calls copyStableCodexRollout with no AbortSignal check. MAX_ROLLOUT_EXPORT_ATTEMPTS = 2 src/lib/codex-browser-export.ts:64.
  • Impact: UI export polling can be cancelled via AbortSignal in download.ts, but the rollout mutation retry will continue to sleep/retry even after abort. Hanging streams/files remain and the download poll never terminates cleanly.
  • Suggested fix: Accept signal?: AbortSignal in withStableRolloutSnapshot and renderCodexThreadDownload/renderCodexThreadsDownload, call throwIfAborted(signal) at top of each iteration and before copyStableCodexRollout. Propagate signal through copyStableCodexRollout so stat/copy can be aborted.

Medium

4. Antigravity keychain secret read per capability → repeated OS prompts under concurrency

  • File/path: src/lib/antigravity-keychain.ts:208-218 withAntigravityDecryptionCapability
  • Evidence: Each call does keychainSecret = await readAntigravityKeychainSecret() via security find-generic-password. No per-session memoisation; the previous global cache was removed.
  • Impact: Concurrent transcript parsing / multiple export requests trigger multiple security subprocesses, causing repeated macOS keychain UI prompts and extra latency. src/lib/antigravity-db.ts:241-423 streaming parser calls decryption for each record set.
  • Suggested fix: Make decryption capability request-scoped with a single secret fetch per logical operation, e.g., memoise the secret for the duration of withAntigravityDecryptionCapability and allow callers to reuse the capability. Avoid spawning security for every record batch.

5. Cursor prune rollback does not cover transcript directory removal

  • File/path: src/lib/cursor-recovery.ts:530-547 pruneCursorThreads
  • Evidence: pruneWorkspaceBuckets rollback is executed on pruneGlobalThreads failure. Transcript dirs are removed afterwards via pruneTranscriptDirs src/lib/cursor-recovery.ts:648-654 with no rollback path. If rm fails partially, DB is already committed.
  • Impact: Partial failure leaves DB entries deleted but on-disk transcript directories remain, or vice-versa, breaking consistency guarantees expected for destructive operations.
  • Suggested fix: Perform transcript removal inside the same transactional window or capture a pre-delete list and restore on error. At minimum, move transcript deletion before DB commit or make it idempotent with a compensating step.

6. Cline legacy data removal risks silent data loss without migration warning

  • File/path: src/lib/cline-db.ts discovery paths; change set notes “migrated entirely to ~/.cline/data session storage, dropped legacy taskHistory.json/ui_messages.json”.
  • Evidence: No fallback discovery for legacy VS Code JSON layout is present in current source. Existing tests reference state/taskHistory.json only in cline-db.test.ts:235.
  • Impact: Users with older Cline installations will see empty workspace/thread lists with no migration hint, a regression for the “threads/workspaces display properly” requirement.
  • Suggested fix: Add a one-time migration scan for legacy taskHistory.json/ui_messages.json locations under ~/.cline and emit a warning / copy sessions into new layout, or at least surface a diagnostic when sessions are missing.

Medium/Low

7. Rollout mutation retry bounds and no backoff

  • File/path: src/lib/codex-browser-export.ts:64,177-200
  • Evidence: MAX_ROLLOUT_EXPORT_ATTEMPTS = 2 with immediate retry on CodexRolloutMutationError. No delay between attempts.
  • Impact: Under concurrent Codex writes, two attempts are often insufficient; busy-loop wastes I/O and increases failure rate for batch exports.
  • Suggested fix: Increase bound, add exponential backoff with abort checks, and surface unstable manifest entries as already done.

8. Partial export manifest ZIP validity edge case

  • File/path: src/lib/codex-browser-export.ts:516-524,535
  • Evidence: Manifest is written to bundleDirectory, then zipExportDirectory(bundleDirectory, zipPath) is awaited, and cleanupExportWorkspace(bundleDirectory) runs in finally. If zipExportDirectory throws after partially writing the zip, the temporary directory is removed on error, losing the manifest for debugging.
  • Impact: Archive-wide failures lose diagnostic manifest; users get opaque error.
  • Suggested fix: Write manifest to a durable location before zipping, or copy manifest out before cleanup. Ensure ZIP is created from a stable snapshot and cleanup only after successful zip completion.

9. download.ts abort listener management

  • File/path: src/ui/lib/download.ts:64-83 raceWithAbort
  • Evidence: Listener removed in finally, but raceWithAbort is also used for sleep which already respects signal. Double abort handling can cause unhandled rejections if the underlying promise rejects after abort.
  • Impact: Potential hanging timers and stray event listeners under rapid cancel/resume cycles.
  • Suggested fix: Use signal.addEventListener once per operation and ensure both fetch and sleep are aborted via signal only, avoiding the extra race wrapper.

These items address the reviewer focus areas: Cursor deletion safety & rollback, export cancellation/retry bounds, Cline legacy removal regression, Antigravity keychain scoping, and partial export manifest robustness.

1. CRITICAL — Codex multi-database delete is not crash-atomic across DB files

File: src/lib/codex-browser-db.ts:1706-1730
Evidence: The comment on line 1706-1707 explicitly acknowledges: "A process crash during WAL commit is not claimed to be crash-atomic across both database files." The ATTACH DATABASE + cross-DB transaction is used without any WAL checkpoint or backup strategy. If the process crashes between the main DB commit and the session index rewrite, the session index.jsonl can become stale (pointing to deleted threads) or the history DB can have orphaned rows.
Impact: On crash, the Codex state DB may contain threads whose rollout files and history rows have already been deleted, leading to a "missing rollout" error on next browse, or orphaned history rows that silently grow the DB.
Fix: Consider a two-phase approach: (1) mark threads as deleted in the state DB first, (2) remove history/session files in a second pass with idempotent cleanup on next browse. Alternatively, write a crash-recovery marker file before starting the multi-DB transaction and check for it on startup to reconcile.


2. HIGH — Cursor workspace bucket deletion does not guard against symlinked bucket directories

File: src/lib/cursor-recovery.ts:660-698
Evidence: deleteCursorWorkspaceBuckets resolves bucketRoot via path.resolve(path.dirname(bucket.workspaceJsonPath)) and validates it equals workspaceStorageDir/bucketId. However, path.resolve follows symlinks in the components of the path. If the workspaceStorageDir itself is a symlink (common on macOS via Homebrew or custom setups), path.resolve does NOT resolve it, so the path.dirname(bucketRoot) !== workspaceStorageDir check could compare a resolved bucket root against an unresolved storage dir, bypassing the safety check. Only realpath on bucketRoot (line 675) catches this, but if the bucket directory has already been deleted, realpath returns null and the check on line 681 compares null dirname against canonicalStorageDir, which would pass.
Impact: A crafted or symlinked workspace.json could cause rm(bucketRoot.path, { force: true, recursive: true }) to delete a directory outside the workspace storage.
Fix: When realpath returns null (ENOENT), skip the bucket (it's already gone) rather than proceeding with deletion. Also, resolve the workspace storage dir itself with realpath before comparison.


3. HIGH — Rollout snapshot retry compares metadata that can change without mutation

File: src/lib/codex-rollout-snapshot.ts:99-106
Evidence: isSameIdentity compares changeTimeMs, modificationTimeMs, sizeBytes, and inode. On some filesystems (e.g., APFS), ctime can change due to metadata-only operations (e.g., chmod, xattr updates) without any content mutation. The inode field also changes if the file is replaced (atomic write by Codex). This means a metadata-only touch between stat(sourcePath) before copy and after copy triggers CodexRolloutMutationError even though the content is identical.
Impact: False-positive retry failures for rollout exports when Codex performs non-content file operations (e.g., permissions, xattr), causing CodexRolloutMutationError to be thrown even though the exported content is valid.
Fix: Add a content-level comparison (e.g., comparing a hash of the first/last few bytes, or comparing sizeBytes alone as a minimum guard) to distinguish metadata changes from actual content mutations. Alternatively, document that CodexRolloutMutationError can be spurious and let callers catch/retry.


4. HIGH — Antigravity withAntigravityDecryptionCapability reads keychain on every call

File: src/lib/antigravity-keychain.ts:208-218
Evidence: withAntigravityDecryptionCapability calls readAntigravityKeychainSecret() (which shells out to security find-generic-password) on every invocation. The comment in the reviewer focus says "verify that removing global caching properly handles concurrent decryption requests without repeated OS keychain prompts." Each concurrent UI request triggers a separate security subprocess. On macOS, this can prompt the user for keychain access repeatedly (once per request), and under concurrent requests (batch export), it creates N simultaneous security processes.
Impact: Repeated OS keychain unlock prompts and potential EPERM/cancellation when multiple export requests hit the server concurrently. The execFile call has a 10-second timeout, so slow keychain access under contention can cause request failures.
Fix: Consider a short-lived in-memory cache (e.g., 5-10 second TTL) for the keychain secret, or use a request-scoped promise deduplication pattern (e.g., Promise.withResolvers() shared across concurrent callers in the same tick) to avoid redundant subprocess spawns.


5. HIGH — Cline deleteClineTask removes session directory before confirming index cleanup result

File: src/lib/cline-db.ts:543-566
Evidence: deleteClineTask calls deleteClineSessionIndex (which deletes the SQLite row), then calls rm(sessionDir, { force: true, recursive: true }). The SQLite deletion at line 394 uses a bare database.prepare(...).run() without a transaction or BEGIN IMMEDIATE. If the SQLite delete fails (e.g., locked DB), the session directory is still deleted at line 556, leaving an orphaned index entry that references a non-existent session.
Impact: The sessions.db index retains a phantom entry for a deleted session. On subsequent list operations, this could cause the UI to show a task that cannot be opened, or cause errors when trying to read the (now-deleted) session files.
Fix: Wrap deleteClineSessionIndex and rm(sessionDir) in a try/catch where if the index delete fails, the directory removal is skipped, or at minimum log a warning that the index entry could not be cleaned up. The current code silently returns { status: 'failed' } but proceeds to delete the directory anyway.


6. HIGH — Codex deleteThreadIds does not handle ATTACH DATABASE failure cleanly

File: src/lib/codex-browser-db.ts:1689-1737
Evidence: If transactionDb.query('ATTACH DATABASE ? AS codex_history').run(historyDbPath) fails (e.g., corrupt history DB, permission error), the exception is caught inside withSqliteTransaction, which rolls back the main DB transaction. However, historyAttached is set to true before the ATTACH succeeds (line 1708-1709), so the finally block at line 1722-1730 tries to DETACH DATABASE codex_history on a connection where ATTACH never succeeded, which throws a SQLite error. This error is caught and logged, but the outer function still returns deletedThreadIds as empty (the rollback undid the state deletes) while threadTargets may have been partially populated.
Impact: The caller may receive an empty deletedThreadIds array even though getThreadDeleteTargets found matching threads, leading to no session file cleanup being attempted. The user sees "thread not found" on retry.
Fix: Move historyAttached = true after the ATTACH succeeds, or check historyAttached only after a successful ATTACH. Also, ensure the function returns consistent results when the transaction is rolled back (either all or nothing).


7. MEDIUM — codex-rollout-snapshot.ts retry loop has no backoff delay

File: src/lib/codex-browser-export.ts:177-206
Evidence: withStableRolloutSnapshot retries on CodexRolloutMutationError up to MAX_ROLLOUT_EXPORT_ATTEMPTS (2) with no delay between attempts. If Codex is actively writing to the rollout file, the second attempt is almost guaranteed to also detect a mutation, resulting in immediate failure.
Impact: The retry mechanism provides no benefit when Codex is actively writing; it only helps for transient single-write races. Users see a confusing error with no indication that the file was being actively modified.
Fix: Add a short delay (e.g., 100-250ms) between retry attempts, or re-read the file size to detect if the file has stabilized before re-attempting the copy.


8. MEDIUM — Cursor bucket rollback in pruneWorkspaceBuckets does not restore snapshots atomically

File: src/lib/cursor-recovery.ts:614-627
Evidence: The rollback function iterates updatedPaths in reverse order, calling restoreBucketComposerData for each. If one bucket's restoreBucketComposerData succeeds but a later one fails, the AggregateError is thrown, leaving the remaining buckets in a partially rolled-back state. The error is caught by the caller at line 536-540, but the caller re-throws, meaning the user sees the error with no ability to retry the partial rollback.
Impact: After a failed multi-bucket deletion, some buckets may have the old data while others have the new data, making the workspace state inconsistent. Recovery requires manual DB editing.
Fix: If any rollback fails, log the partial rollback state and provide a recovery path (e.g., return a result object with rolledBackBuckets and failedBuckets rather than throwing an AggregateError that discards the success information).


9. MEDIUM — codex-browser-db.ts deleteStateThreadRows does not batch-delete across the state/history split correctly

File: src/lib/codex-browser-db.ts:1715-1719
Evidence: The loop at line 1715-1719 iterates uniqueThreadIds in chunks. For each chunk, stateThreadIds filters to only IDs found in existingIdSet (the threads table). But deleteHistoryThreadRows is called with the full threadIdChunk (line 1718), not stateThreadIds. This means if a thread ID exists in the history DB but not in the state DB (e.g., a fallback thread), the history rows are still deleted even though the state rows were not.
Impact: Deleting a fallback thread's history but not its state rows could leave inconsistent state if the thread later gets re-indexed. More importantly, the return value existingIds only includes state-DB thread IDs, so the caller won't know the history was partially cleaned.
Fix: Pass threadIdChunk to deleteHistoryThreadRows only for threads that should be cleaned up (consistent with the caller's intent), or document that history cleanup is always best-effort for all requested IDs.


10. MEDIUM — conversation-zip-export.ts creates workspace in os.tmpdir() but cleans up with rm(zipPath) in finally

File: src/lib/conversation-zip-export.ts:65-84
Evidence: Line 66 creates zipPath in os.tmpdir(), and line 83 cleans it up with rm(zipPath, { force: true }). However, if zipExportDirectory succeeds and the Blob is created, the zipPath file is deleted in the finally block, but the Blob was created from its contents via arrayBuffer(). This is fine for the Blob, but if the function is interrupted between zipExportDirectory and Blob creation, the zip file leaks in os.tmpdir().
Impact: Under repeated failed exports, orphaned zip files accumulate in os.tmpdir(). On macOS, this directory is cleaned on reboot, but long-running servers may accumulate significant disk usage.
Fix: This is a minor operational concern. Consider writing zip files to a dedicated export directory (like source-session-export-server.ts does) instead of os.tmpdir(), or accept the leak with a comment explaining the tradeoff.


11. MEDIUM — antigravity-server.ts redefines AntigravityDecryptionCapabilityError

File: src/ui/lib/antigravity-server.ts:42-49
Evidence: AntigravityDecryptionCapabilityError is defined identically in both antigravity-server.ts (line 42) and antigravity-keychain.ts (line 23). The server file's isAntigravityDecryptionCapabilityError check (line 56-60) uses instanceof against the local class, which will NOT match instances of the class from antigravity-keychain.ts.
Impact: If acquireAntigravityDecryptionCapability throws an AntigravityDecryptionCapabilityError from the antigravity-keychain module, the instanceof check in isAntigravityDecryptionCapabilityError will return false, and the error will propagate as an unhandled decryption capability error instead of being caught and converted to a user-friendly "Unlock keychain" message.
Fix: Import AntigravityDecryptionCapabilityError from @spiracha/lib/antigravity-keychain instead of re-defining it locally, or use the .code property check (which is already present as a fallback) as the primary check.


12. MEDIUM — download.ts delay function references window.setTimeout/window.clearTimeout

File: src/ui/lib/download.ts:87-106
Evidence: The delay function uses window.setTimeout and window.clearTimeout. This is fine for browser context, but the delay function is also used as the default sleep parameter in waitForDownloadUrlAvailability and downloadUrlFile, which could be called from server-side test contexts. The DownloadTextOptions type allows injecting a custom schedule, but DownloadUrlOptions defaults to delay which hardcodes window.
Impact: If any export/download path is invoked from a non-browser environment (e.g., SSR, server function, or Vitest), window is not defined error occurs.
Fix: Use globalThis.setTimeout/globalThis.clearTimeout instead of window.*, which works in both browser and Node/Bun contexts.


13. MEDIUM — Codex assertSafeCodexRolloutPaths is not visible but session file deletion relies on it

File: src/lib/codex-browser-db.ts:1765-1770
Evidence: validateSessionFileDeletionTargets calls assertSafeCodexRolloutPaths, but deleteSessionIndexEntriesForThreads at line 1909-1914 calls deleteThreadSessionFiles with the result of getSessionFilesForThreadIds WITHOUT calling validateSessionFileDeletionTargets first. The validation is only called in the batch delete flow (line 1902-1922) but not in the single-thread path that goes through deleteSessionIndexEntriesForThreads.
Impact: Single-thread deletion could remove session files without validating they are safe Codex rollout paths, potentially deleting files outside the expected directory if a thread's rollout_path is malformed.
Fix: Ensure validateSessionFileDeletionTargets is called in all deletion paths, or ensure assertSafeCodexRolloutPaths is called before deleteThreadSessionFiles in deleteSessionIndexEntriesForThreads.


14. LOW — codex-browser-db.ts readThreadBrowseDatabaseData uses SQLITE_DELETE_BATCH_SIZE for browse queries

File: src/lib/codex-browser-db.ts:2177
Evidence: The browse data reader uses SQLITE_DELETE_BATCH_SIZE (designed for batch deletes) to chunk browse queries. This value may be optimized for write batching rather than read performance. If the batch size is too large for reads (e.g., 500+ thread IDs in a WHERE IN clause), it could hit SQLite's variable limit or cause slow query planning.
Impact: Minor performance concern for very large batch exports with hundreds of thread IDs.
Fix: Either use a separate BROWSE_READ_BATCH_SIZE constant or document why SQLITE_DELETE_BATCH_SIZE is appropriate for both use cases.


15. LOW — cursor-recovery.ts scoreComposer uses arithmetic on timestamps

File: src/lib/cursor-recovery.ts:174-175
Evidence: scoreComposer adds Number(Boolean(entry.name)) + Number(entry.lastUpdatedAt ?? 0) + Number(entry.totalLinesAdded ?? 0). Timestamps (lastUpdatedAt) are in epoch milliseconds (typically 13+ digits), while totalLinesAdded is a small integer. The arithmetic sum is dominated by the timestamp, making the name and totalLinesAdded contributions negligible in comparison. This isn't a bug per se, but the scoring function doesn't normalize values, so it behaves as a "prefer newer" sort with minimal weight from other fields.
Impact: Low — the function still works as a tiebreaker, but the name and line-count signals are effectively ignored.
Fix: Either normalize timestamps to a smaller range before summing, or use a lexicographic sort with explicit priority (timestamp first, then name presence, then line count).

1. pruneCursorThreads directory unlink can target paths outside the validated subtree if a symlinked path passes the canonical check but not the un-canonical one (or vice versa) — defense depends on path-identity, not containment.

  • Severity: HIGH
  • File: src/lib/cursor-recovery.ts:486-505
  • Evidence: The loop validates each transcript dir with two separate checks: a structural un-canonical check (resolvedProjectsDir !== projectsDir) and a canonical-relative check. The structural check uses path.resolve (no symlink resolution), so any path whose 3-ancestor un-canonical path string-equals the configured projectsDir passes. If userDir itself or any ancestor of a transcript dir is a symlink that the user did not create, two resolved paths can be string-equal but point to different filesystem locations; conversely, the same physical dir can be reached through two non-equal strings and be rejected even when safe.
  • Impact: Either false positives (refusing to delete legitimate dirs) or false negatives (deleting dirs the user did not intend). Combined with await rm(dir, { force: true, recursive: true }) on the next loop, false negatives are destructive.
  • Suggested fix: Replace the dual-check with a single canonical-relative check. Resolve the canonical projectsDir once, then for every transcript dir compute path.relative(canonicalProjectsDir, canonicalDir), reject any result starting with .., absolute, or empty, and skip the un-canonical structural check entirely. Optionally also assertSafeCursorComposerId on path.basename(canonicalDir).

2. opencode-db.ts silently falls back from a read-only SQLite open to a read-write open, which can create -wal/-shm sidecars on the user's machine.

  • Severity: HIGH
  • File: src/lib/opencode-db.ts:209-217
  • Evidence: openOpenCodeReadDb tries mode=ro first; on any error it re-opens with mode=rw and the SQLITE_OPEN_READWRITE flag. It then sets PRAGMA query_only = ON. Opening a WAL SQLite DB in read-write creates/refreshes sidecar files even if no writes occur, and query_only does not block all writes (e.g. PRAGMA wal_checkpoint).
  • Impact: A read-only browse operation can leave visible side effects on the user's OpenCode SQLite file. In addition, subsequent code paths that assume "this DB connection is readonly" (e.g. callers relying on no journal writes for race-safety) can be surprised.
  • Suggested fix: Remove the silent fallback, or at minimum log a warning and gate it on a feature flag. Use a try/catch around a single read-only open and surface the error to the caller.

3. cursor-recovery.ts writes backups with non-atomic Bun.write and direct Bun.write(backupPath, JSON.stringify(value)), leaving backups that can be torn or half-written if the process is interrupted mid-write.

  • Severity: HIGH
  • File: src/lib/cursor-recovery.ts:71-83
  • Evidence: writeRetainedCursorBackup does await Bun.write(backupPath, JSON.stringify(value)) with no temp file, no rename, no fsync. The backup is then used as the rollback target for both recoverCursorWorkspaceGroup and pruneCursorThreads.
  • Impact: A torn backup means the rollback reads a half-written JSON, throws, and the recovery/deletion leaves the cursor DB in a state with no working backup. The user has no recourse.
  • Suggested fix: Use a temp-file + rename pattern (matches what writeOpenCodeDesktopState already does in opencode-db.ts:945-955), and call fsync before rename if the host platform supports it. Apply this to all writeRetainedCursorBackup callers (composer headers and pruned threads).

4. mapWithConcurrency "fail-fast" does not cancel in-flight destructive operations; partial effects commit before the error surfaces.

  • Severity: HIGH
  • File: src/lib/concurrency.ts:16-37
  • Evidence: The failed flag is checked at the top of each worker iteration, but workers that are already awaiting a long task (e.g. await rm(dir, { force: true, recursive: true })) continue to completion. The promise eventually rejects with the first error, but the in-flight side effects are not rolled back. The pruneTranscriptDirs use site (cursor-recovery.ts:648-654) and deleteThreadSessionFiles (codex-browser-db.ts:1739-1746) both rely on this pattern.
  • Impact: For a 1000-thread deletion, when one rm fails, ~9-19 in-flight rm calls (concurrency=4 per the limiter) still complete and permanently delete directories before the caller sees the error. The error response says "failed" but the UI cannot easily tell which threads were already deleted.
  • Suggested fix: Either (a) make the per-task effect idempotent (e.g. pre-check existence, re-check after rm), or (b) introduce a per-task AbortSignal and pass it into the destructive operations. For rm, also catch and record per-entry errors into a result object so the caller knows exactly what was and was not deleted.

5. codex-browser-export.ts batch export can leak archive zip files in publicExportDir if the export throws after zipExportDirectory succeeds, because the zip is in exportDir not in the bundleDirectory that gets cleaned up.

  • Severity: HIGH
  • File: src/lib/codex-browser-export.ts:491-536
  • Evidence: bundleDirectory is created via mkdtemp and cleaned in finally. zipPath is built via buildUniqueArchivePath(exportDir, exportBaseName) and points inside exportDir (not the bundle). If zipExportDirectory throws (e.g. disk full, write race), the finally cleans the bundle but does not clean the partially-written zipPath.
  • Impact: Repeated failed batch exports leak unbounded zip files into the user's public export dir, which is served as a download endpoint (buildUiExportDownloadUrl in ui-export-files.ts). Old zips are addressable from the UI server even though they belong to a failed/aborted export.
  • Suggested fix: After zipExportDirectory, in the catch block also await rm(zipPath, { force: true }) if it exists. Alternatively, place the zip inside the bundle and move it to the public dir only after the bundle is zipped successfully.

6. deleteAntigravityConversation invokes removeConversationFromSummaryIndex twice (once eagerly, once during cleanup) with no error handling on the second call, and reads the entire summary file into memory on both passes.

  • Severity: HIGH
  • File: src/lib/antigravity-db.ts:732-783, 1557-1601
  • Evidence: removeAntigravityConversationFromRoots calls removeConversationFromSummaryIndex per root. Then waitForAntigravityConversationCleanup calls it again per root. Each call does new Uint8Array(await Bun.file(summaryPath).arrayBuffer()) — full-file read. The streaming protobuf reader (readAntigravityProtobufRecords) is NOT used here. The second call has no try/catch.
  • Impact: A second-call failure throws out of deleteAntigravityConversation after the first call already deleted the per-conversation files. The summary index still references a conversation whose transcript no longer exists, producing a "ghost" entry on next launch. The duplicate full-file read also undoes the "stream large Antigravity JSONL" goal from issue Stream and harden Antigravity summary/transcript parsing #28 for the summary index path.
  • Suggested fix: Wrap the second removeConversationFromSummaryIndex in a try/catch that records but does not rethrow (it is best-effort). Replace the full-file read with a streaming pass that uses readAntigravityProtobufRecords plus a writer that re-emits retained records back to the same path, to keep the streaming discipline consistent across the file.

7. withAntigravityDecryptionCapability does not cache the keychain secret at all; concurrent or repeated decrypts in the same process spawn one security find-generic-password per call.

  • Severity: MEDIUM
  • File: src/lib/antigravity-keychain.ts:208-218
  • Evidence: Each call invokes readAntigravityKeychainSecret, which runs execFile('security', ['find-generic-password', ...]). The previous behavior cached process-wide; the new behavior re-execs on every request. The reviewer focus explicitly called out that the new scoped state must not "cause repeated OS keychain prompts".
  • Impact: A single UI page load that decrypts N Antigravity conversations triggers N security execs. On a non-jailbroken keychain each call can block until the previous exec releases; in the worst case (a denied or rate-limited keychain) the UI times out per-conversation instead of failing once.
  • Suggested fix: Memoize the secret at the acquireAntigravityDecryptionCapability call site (one fetch per server function call), and let the outer antigravity-server.ts re-acquire per request. The current code already does this implicitly (one capability per request), but if a request decrypts multiple conversations the helper is called once per conversation, not once per request. Move the acquireAntigravityDecryptionCapability to wrap the entire render pipeline, not each conversation.

8. pruneCursorThreads validation uses realpath only on the transcript dir, not on projectsDir itself, and falls back to the un-resolved path on ENOENT — leaving the un-canonical check as the only defense for a missing projects root.

  • Severity: MEDIUM
  • File: src/lib/cursor-recovery.ts:486-505
  • Evidence: const canonicalProjectsDir = await realpath(projectsDir).catch(() => projectsDir); returns projectsDir on ENOENT. If a user's first-time ~/.cursor/projects has not yet been created (or was moved), canonicalProjectsDir === projectsDir and the canonical-relative check uses the un-canonical value. Then a transcript dir whose canonical path matches by string is allowed.
  • Impact: A user with a transient/missing projects dir could see false negatives (transcript dirs rejected) or false positives (unintended dirs deleted) depending on the exact path layout.
  • Suggested fix: If realpath of projectsDir fails with ENOENT, treat the request as "nothing to delete" and short-circuit (return early with empty transcriptDirsRemoved), rather than continuing with a possibly-mismatched canonical root.

9. withCursorWriteTransaction uses BEGIN IMMEDIATE but the action is allowed to call into JS code (e.g. removeThreadFromBucket reads from the DB and writes JSON to it) that may also depend on the same connection; a logic error inside the callback can leave the DB in a half-mutated state that the ROLLBACK does not undo (e.g. side effects on the filesystem).

  • Severity: MEDIUM
  • File: src/lib/cursor-db.ts:92-123 used by cursor-recovery.ts:337-339, cursor-recovery.ts:390-397
  • Evidence: SQLite rolls back the SQL changes, but pruneWorkspaceBuckets does multiple separate withCursorWriteTransaction calls — one per bucket — instead of one transaction across all buckets. A failure in bucket 2 leaves bucket 1 committed, even though the surrounding pruneCursorThreads reports an error and tries to roll back via the snapshot mechanism.
  • Impact: Partial bucket mutation across buckets is not atomic. If the rollback path itself fails (e.g. bucket DB was concurrently deleted by Cursor), the user is left with inconsistent bucket state across workspaces.
  • Suggested fix: Consider using savepoint per bucket inside one outer BEGIN IMMEDIATE, or accept that the current best-effort two-phase (SQL transaction + JS snapshot rollback) is the design and document that. At minimum, log which bucket paths were committed-but-not-rolled-back when an AggregateError is thrown from the rollback, so the user can manually clean them up.

10. antigravity-trajectory.ts and antigravity-db.ts carry near-duplicate protobuf parsers, and the trajectory parser is not hardened against wire types outside the supported set the way the antigravity-db parser is.

  • Severity: MEDIUM
  • File: src/lib/antigravity-trajectory.ts:73-114 vs src/lib/antigravity-db.ts:191-239
  • Evidence: parseProtoFields in both files is structurally identical, but the trajectory version throws on unsupported wire types (throw new Error('Unsupported Antigravity trajectory protobuf wire type: ${wireType}')), while the antigravity-db version also throws. The trajectory code wraps each parseTrajectoryStep in try/catch and produces a diagnostic — good. But readAntigravityTrajectoryStepIndexes is exported and may be used without the per-step try/catch wrapper; if a single bad step throws, the whole read fails.
  • Impact: A single corrupt step blocks reading the rest of the trajectory. The streaming reader in antigravity-db.ts already has the right pattern; trajectory reads should be consistent.
  • Suggested fix: Extract a shared parseProtoFields into a small protobuf.ts module. Wrap readAntigravityTrajectoryStepIndexes so a single bad step does not abort the whole read (use the same per-step try/catch that readAntigravityTrajectoryEntriesWithDiagnostics already has).

11. cursor-db.ts readBubbleStats reads every bubble row in the multi-GB global DB whenever the caller does not pass an id list (i.e. the default list and detail paths).

  • Severity: MEDIUM
  • File: src/lib/cursor-db.ts:932-956
  • Evidence: When ids is null/undefined, the query is SELECT ... FROM cursorDiskKV WHERE key GLOB 'bubbleId:*:*' GROUP BY id. There is no LIMIT, no WHERE filter on composer id, no use of a covering index. For users with millions of bubbles this is a multi-second scan that runs on every list request.
  • Impact: Slow list rendering for power users, especially when combined with the already-expensive readAllHeads and readHeaderInfo queries inside the same withCursorReadonlyDb block.
  • Suggested fix: For the "all composers" case, run the per-composer countBubblesForComposerIds query (already exists in cursor-recovery.ts:283-301) only over the resolved composer ids, instead of a full DB scan. The current "scan everything" is only needed for the un-filtered dashboard path and should be explicitly opt-in.

12. download.ts triggerAnchorDownload removes the anchor element immediately after link.click(), which can race with the browser's download handoff in some engines.

  • Severity: MEDIUM
  • File: src/ui/lib/download.ts:117-124
  • Evidence: The function appends, clicks, then removes the anchor synchronously. There is no requestAnimationFrame or microtask defer. In Safari especially, removing the anchor before the click handler completes can cancel the download.
  • Impact: Sporadic failed downloads in Safari. The test suite passes because it uses jsdom which doesn't enforce this behavior.
  • Suggested fix: Wrap the link.remove() in setTimeout(..., 0) or use a requestAnimationFrame so the browser has a tick to start the download.

13. codex-rollout-snapshot.ts copyStableCodexRollout does not validate that the snapshot write actually succeeded (e.g. by re-stating) — the identity check is performed only on the source file before and after the copy.

  • Severity: MEDIUM
  • File: src/lib/codex-rollout-snapshot.ts:123-147
  • Evidence: Bun.write(snapshotPath, Bun.file(sourcePath)) returns a Promise<number> (bytes written) but the code throws away the return value. The isSameIdentity check then compares the source file's pre/post stats. If the copy silently truncates (e.g. filesystem full mid-write) but the source file is not mutated (e.g. write goes to a different file), the export will use a truncated snapshot.
  • Impact: A truncated export that nonetheless passes the mutation check is delivered to the user as a "ready" download. The user only notices when the file is incomplete.
  • Suggested fix: await Bun.write(snapshotPath, Bun.file(sourcePath)) returns the bytes written; compare to before.sizeBytes and throw a new error class (e.g. CodexRolloutSnapshotIncompleteError) if the count does not match. Optionally re-stat the snapshot file and check its size matches.

14. opencode-db.ts writeOpenCodeDesktopState reads filePath mode with stat; if the file is removed between the caller reading and writing, the stat throws and the function returns an unhandled error to the delete flow.

  • Severity: LOW
  • File: src/lib/opencode-db.ts:945-955
  • Evidence: const mode = (await stat(filePath)).mode & 0o777; — no try/catch and no fallback. The caller in deleteOpenCodeDesktopSessionState reads the file with Bun.file(filePath).text() first, then if the file disappears before writeOpenCodeDesktopState runs (e.g. another Cursor/OpenCode process), the write aborts.
  • Impact: The delete operation reports failure to the user for a benign race, and the file is not cleaned.
  • Suggested fix: Wrap the mode read in try/catch and default to 0o644 on ENOENT, or call stat on the temp file path after writing (Bun's Bun.write creates the file with default mode).

15. deleteCursorWorkspaceHistory silently skips directories with corrupt or oversized entries.json, leaving orphan history entries on disk with no log or diagnostic.

  • Severity: LOW
  • File: src/lib/cursor-recovery.ts:780-789
  • Evidence: try { data = (await Bun.file(path.join(entryPath, 'entries.json')).json()) ... } catch { continue; } — no logging, no counter, no return value to surface.
  • Impact: A user with a corrupted Cursor history gets a silent partial cleanup and no indication that history remains.
  • Suggested fix: Track a skipped count and return it from deleteCursorWorkspaceHistory, and log a warning per skipped entry. Optionally distinguish ENOENT from JSON parse errors so the UI can display a hint.

16. download.ts isReadyStatus treats HTTP 405 as "ready" without a comment explaining why.

  • Severity: LOW
  • File: src/ui/lib/download.ts:126-128
  • Evidence: (status >= 200 && status < 400) || status === 405. The 405 special case is undocumented. 405 means "the URL exists but HEAD is not allowed"; the implicit assumption is "GET will work". A misconfigured server that returns 405 for both HEAD and GET will then fail at the anchor click, with no failed state shown to the user (the click opens a blank tab).
  • Impact: Wrong-looking failures on misconfigured exports.
  • Suggested fix: Add a comment explaining the 405 assumption. Consider a small whitelist: only treat 405 as "ready" if the response is from the same origin or a known-spiracha endpoint, or fall back to GET (range 0–0) instead of HEAD.

17. codex-browser-db.ts readThreadBrowseDatabaseData uses a BEGIN DEFERRED read transaction over multiple chunked queries; a concurrent Codex writer can update the threads table between the schema check and the SELECT, but the schema compatibility check is only run once at the top.

  • Severity: LOW
  • File: src/lib/codex-browser-db.ts:2164-2195
  • Evidence: withSqliteTransaction(db, (snapshotDb) => { ... assertCodexSchemaCompatibility ... }). The transaction is BEGIN DEFERRED, so the first read acquires a SHARED lock; this prevents writers, so the snapshot is consistent for the read. But the lock is released when the transaction commits. Fine for the read snapshot. However, the function reads the DB outside of a writer-resistant transaction, so a deleteCodexThread running concurrently with getThreadBrowseDataBatch can succeed in deleting threads between the schema check and the SELECT, leading to a "found" status for a thread that no longer exists.
  • Impact: Stale data shown in the UI; the user can attempt to view a deleted thread.
  • Suggested fix: Document the snapshot semantics. The function returns rows from inside a read transaction, but callers (buildThreadBrowseData, buildRecoverResult) read additional state outside the transaction; a "missing" status returned from the function does not mean the thread still exists at the moment the caller acts on it. This is acceptable for browse but should be noted.

18. cursor-recovery.ts deleteCursorWorkspaceBuckets updates removed only after the rm call returns; if a directory was already absent, canonicalBucketRoot !== null is false, so the bucket is not counted toward removed but is still passed to rm({ force: true, recursive: true }) — no-op but with side effects on the discovery cache invalidation timing.

  • Severity: LOW
  • File: src/lib/cursor-recovery.ts:685-696
  • Evidence: bucketRoots.push({ exists: canonicalBucketRoot !== null, path: bucketRoot }); then removed += Number(bucketRoot.exists). If canonicalBucketRoot is null, the bucket is "absent" and removed doesn't increment. The invalidateCursorDiscoveryCache() is called in finally regardless. The cache is also invalidated elsewhere on the same path, leading to multiple invalidations per delete.
  • Impact: Multiple cache invalidations in a row (cheap but wasteful); no real correctness impact.
  • Suggested fix: Either skip the rm for absent buckets, or document the redundant invalidation as intentional.

19. codex-browser-export.ts withStableRolloutSnapshot re-reads the browse data on every retry via getThreadBrowseData instead of re-using initialBrowseData for the second attempt's metadata.

  • Severity: LOW
  • File: src/lib/codex-browser-export.ts:177-180
  • Evidence: const browseData = attempt === 1 && initialBrowseData ? initialBrowseData : getThreadBrowseData(dbPath, threadId); — on attempt 2 (the only retry), the browse data is re-read. This is intentional (the rollout may have changed), but it also re-opens the DB connection. The retry path is invoked from withStableRolloutSnapshot, which does not cache the DB handle.
  • Impact: Extra DB open/close per retried export, slow under contention.
  • Suggested fix: Pass the previously-read browse data to retry attempts and only refresh if the new snapshot's before/after stats don't match (which is already how the retry is triggered).

20. cursor-recovery.ts deleteCursorWorkspaceHistory reads entries.json with no size limit, allowing a single corrupt or oversized history entry to consume memory before parsing fails.

  • Severity: LOW
  • File: src/lib/cursor-recovery.ts:782
  • Evidence: await Bun.file(path.join(entryPath, 'entries.json')).json() — no size guard, no streaming.
  • Impact: Memory blow-up on a maliciously large or corrupt entries.json (Cursor's History is local, so the threat model is a local bug, not a network attacker).
  • Suggested fix: stat the file and refuse to parse anything over, say, 32 MB, or stream-parse with a chunked reader.

21. antigravity-transcript-history.ts cacheHistory evicts by insertion order, but getCachedHistory re-inserts on access; under bursty access the cache may evict hot entries if they're inserted at the head.

  • Severity: LOW
  • File: src/lib/antigravity-transcript-history.ts:317-349
  • Evidence: The cache uses Map iteration order. On hit, the entry is deleted and set again, moving to the tail. On eviction, the head is removed. This is LRU-by-access. But: the cacheKey includes the latest commit hash of the transcript, so each new commit creates a new cache key. The cache may not actually reuse entries across commits, providing little benefit.
  • Impact: The cache rarely hits, holding 32 MB of memory for marginal benefit.
  • Suggested fix: Either reduce the cache scope (per currentMinimumStepIndex only) or remove the cache if hit rate is low.

22. download.ts raceWithAbort registers an abort listener even when the underlying promise has already settled; minor allocation, no correctness impact.

  • Severity: LOW
  • File: src/ui/lib/download.ts:64-83
  • Evidence: The function always creates the abortPromise and registers the listener, even when the source promise has no chance to be aborted. The cleanup removeEventListener runs unconditionally.
  • Impact: Negligible allocation pressure on every probeDownloadUrl call. Six retries by default = six AbortController allocations per file.
  • Suggested fix: For known-fast operations, pass a no-op signal handler. Or guard the listener registration: if (signal && !signal.aborted) { signal.addEventListener('abort', onAbort, { once: true }); }.

23. cursor-recovery.ts deleteCursorWorkspaceBuckets has its try/finally around the rm loop, but invalidateCursorDiscoveryCache() is inside the finally. The cache invalidation also happens earlier in pruneCursorThreads and deleteCursorWorkspaceBuckets's caller — multiple cache flushes per user action.

  • Severity: LOW
  • File: src/lib/cursor-recovery.ts:688-697
  • Evidence: invalidateCursorDiscoveryCache() runs in finally here, and also at pruneCursorThreads end (line 544) and after recoverCursorWorkspaceGroup (line 348).
  • Impact: Negligible runtime cost; mostly code-clarity.
  • Suggested fix: Document that the multiple invalidations are intentional (defense-in-depth) or consolidate.

24. download.ts cancelActiveDownloads fires a window event that all useDownloadCancellation instances respond to. If two export dialogs are open simultaneously (e.g. opened from two different workspace pages), closing one cancels the other's in-flight download.

  • Severity: LOW
  • File: src/ui/lib/download.ts:181-187, 159-179
  • Evidence: cancelActiveDownloads dispatches a single window event; every active cancellation hook responds. The hook also has a cancellationRequested flag that prevents new downloads from starting, but resets only on the reset event.
  • Impact: Closing one dialog while another is mid-download cancels both. Likely fine in practice (only one dialog visible at a time), but worth a comment.
  • Suggested fix: Scope the event to the originating dialog via a token, or document the global cancel behavior.

🔴 Critical Issues

1. Cursor Workspace Deletion: Incomplete Path Validation Before rm -rf

File: src/lib/cursor-recovery.ts:656-699 (deleteCursorWorkspaceBuckets)
Evidence: Lines 665-673 validate bucketRoot !== dbRoot and path.dirname(bucketRoot) !== workspaceStorageDir, but line 691 calls await rm(bucketRoot.path, { force: true, recursive: true }) without re-verifying the canonical path still resolves inside canonicalStorageDir at deletion time. A TOCTOU window exists between realpath (line 675) and rm (line 691).
Impact: If a symlink is swapped between validation and deletion, arbitrary directories under workspaceStorageDir could be removed.
Fix: Re-validate canonicalBucketRoot immediately before rm or use fs.open with O_NOFOLLOW + unlinkat(AT_REMOVEDIR) equivalent. At minimum, add a second realpath check right before rm.


2. Cursor Prune Rollback: Partial Bucket Rollback Can Leave Inconsistent State

File: src/lib/cursor-recovery.ts:597-646 (pruneWorkspaceBuckets)
Evidence: The rollback function (lines 615-627) iterates updatedPaths.reverse() and calls restoreBucketComposerData. If one bucket restore fails, remaining buckets are not restored (line 620 catches but continues). The AggregateError is thrown after the loop, but the global DB deletion has already succeeded (line 533) and cannot be rolled back.
Impact: Partial bucket rollback leaves some buckets reverted and others not, while global threads are permanently deleted. User sees "rollback failed" but data is already gone.
Fix: Make global deletion conditional on successful bucket updates, or implement a two-phase commit: stage all bucket changes, verify all succeed, then commit global. At minimum, track which buckets failed rollback and include in error message.


3. Codex Rollout Mutation Retry: No Maximum Attempt Bound on Export Entry

File: src/lib/codex-browser-export.ts:166-209 (withStableRolloutSnapshot)
Evidence: MAX_ROLLOUT_EXPORT_ATTEMPTS = 2 (line 64) bounds retries inside withStableRolloutSnapshot, but renderCodexBatchEntry (line 377) calls it per-thread. A batch of 100 threads could trigger 200 rollout copy attempts sequentially with no global budget.
Impact: Under sustained Codex writes, batch exports can spin indefinitely, consuming disk I/O and tmp space.
Fix: Add a batch-level attempt budget (e.g., MAX_BATCH_ROLLOUT_ATTEMPTS = threadCount * 2) and abort the entire batch if exceeded. Track cumulative attempts across threads.


4. Antigravity Keychain: Removed Global Cache Causes Repeated Keychain Prompts

File: src/lib/antigravity-keychain.ts:208-218 (withAntigravityDecryptionCapability)
Evidence: Each call to withAntigravityDecryptionCapability invokes readAntigravityKeychainSecret() (line 213) which runs security find-generic-password (line 191-195). No in-process caching remains.
Impact: Concurrent UI requests (e.g., listing multiple Antigravity sessions) trigger multiple macOS Keychain permission prompts, degrading UX and potentially hitting rate limits.
Fix: Reintroduce a request-scoped cache (e.g., AsyncLocalStorage or a simple module-level Promise<string> memoization with TTL) so concurrent calls within a short window share one keychain read.


5. Cline Legacy Data Removal: Silent Drop of taskHistory.json/ui_messages.json

File: src/lib/cline-db.ts:212-224 (listClineSessionEntries)
Evidence: Discovery now only scans ~/.cline/data/sessions/*/*.json. The old VS Code global storage files (taskHistory.json, ui_messages.json) are completely ignored with no migration warning or fallback.
Impact: Users with pre-migration Cline data (older than ~v3.0) see zero conversations. No error, no migration path.
Fix: Add a one-time migration check: if sessions dir is empty but legacy files exist, log a warning and optionally attempt a read-only import. At minimum, surface a "legacy data detected" notice in the UI source listing.


🟠 High Severity

6. Batch Export Manifest: Invalid ZIP on Archive-Wide Failure

File: src/lib/codex-browser-export.ts:465-556 (renderCodexThreadsDownload)
Evidence: isArchiveWideFailure (lines 245-257) detects CodexDbCompatibilityError and FS errors (EACCES, ENOSPC, etc.). On such errors, the catch block (line 525) re-throws after logging, but the finally block (line 534) cleans up bundleDirectory. The ZIP at zipPath is never created, yet callers may expect a partial ZIP with manifest.
Impact: Callers receive an exception instead of a partial archive. The "partial failure with manifest" design (Issue #20) is not honored for archive-wide failures.
Fix: On archive-wide failure, still write manifest to a temporary location and return a ZIP containing only the manifest (or throw a typed error with the manifest attached).


7. Download Cancellation: AbortSignal Not Propagated to fetch in probeDownloadUrl

File: src/ui/lib/download.ts:189-240 (probeDownloadUrl)
Evidence: probeDownloadUrl creates requestInit.signal = signal (line 203-205) but raceWithAbort (line 208) wraps the fetch. If signal aborts during fetch, the AbortError is caught by asCancellationError (line 227) and re-thrown. However, fetch with signal may not abort synchronously on all platforms, and the HEAD request may complete anyway.
Impact: Cancellation during "preparing" phase may not stop the network request, wasting bandwidth and delaying UI feedback.
Fix: Use AbortController with explicit abort() on the fetch's internal request, or accept that HEAD probes are best-effort and document it.


8. Transcript Load Limiter: Global Concurrency State Not Reset on Error

File: src/lib/transcript-load-limiter.ts:81-149 (runWithTranscriptLoadLimit)
Evidence: The finally block (lines 128-146) decrements counters, but if loader() throws, the error is logged (lines 113-126) and re-thrown. The counters are correctly decremented. However, activeLoadsByIntegration and queuedLoadsByIntegration Maps are never cleared on process shutdown or test teardown, causing cross-test leakage.
Impact: Tests running in parallel may see inflated concurrency counts, causing false limiter throttling.
Fix: Export a resetTranscriptLoadState() function for test cleanup.


9. Cursor Delete: ensureCursorClosedForWrite Uses pgrep -x Cursor Which Misses Helper Processes

File: src/ui/lib/cursor-server.ts:50-57 (ensureCursorClosedForWrite)
Evidence: isCursorRunning (cursor-recovery.ts:54-57) spawns pgrep -x Cursor. Cursor may run helper processes (e.g., Cursor Helper, Cursor GPU) that still hold DB locks.
Impact: Deletion proceeds while Cursor holds SQLite locks, causing SQLITE_BUSY or silent corruption.
Fix: Check for any process with Cursor in name, or better, attempt to open the DB with BEGIN IMMEDIATE and treat SQLITE_BUSY as "Cursor is running".


10. Partial Export: skippedThreadCount Returned But Not Exposed in HTTP API

File: src/lib/codex-browser-export.ts:549-555 (return) vs src/ui/lib/cursor-server.ts:315-325 (exportCursorThreadsFn)
Evidence: renderCodexThreadsDownload returns { skippedThreadCount } (line 554), but the server function exportCursorThreadsFn returns the raw result without surfacing skippedThreadCount to the client.
Impact: UI cannot show "X of Y threads exported" for partial failures.
Fix: Include skippedThreadCount in the server response envelope.


🟡 Medium Severity

11. Cline Adapter: workspacePath Null For session_directory Source Breaks Path Matching

File: src/lib/conversation-data/cline-adapter.ts:95 (buildConversation)
Evidence: workspacePath: task.workspaceSource === 'session_directory' ? null : task.worktree. The ConversationDetail.workspacePath is used by clients for path-scoped collection. Returning null for directory-based workspaces breaks listConversationsForPath filtering.
Impact: Conversations from session_directory workspaces never match cwd filters.
Fix: Always return task.worktree (the actual CWD) as workspacePath. The workspaceSource metadata distinguishes the storage layout.


12. Antigravity History Cache: Unbounded Growth on Cache Miss

File: src/lib/antigravity-transcript-history.ts:317-338 (cacheHistory)
Evidence: MAX_HISTORY_CACHE_BYTES = 32MB and MAX_HISTORY_CACHE_ENTRIES = 32 are enforced, but cacheHistory returns early if bytes > MAX_HISTORY_CACHE_BYTES (line 319-320). A single large history (>32MB) is never cached, causing repeated Git history walks.
Impact: Large Antigravity repos re-fetch history on every request.
Fix: Cache individual snapshots with LRU eviction instead of all-or-nothing.


13. Codex Browser Export: largeExportThresholdBytes Default Not Exposed to UI

File: src/lib/codex-browser-export.ts:63 (LARGE_BROWSER_EXPORT_THRESHOLD_BYTES = 128MB) vs src/ui/components/export-dialog.tsx
Evidence: Single-thread export auto-zips if rollout.before.sizeBytes > largeExportThresholdBytes (line 288). The UI export dialog has no "force zip" option for single threads (only multi-thread).
Impact: Users cannot force ZIP for large single-thread exports that fall under the threshold but would benefit from compression.
Fix: Add forceZipArchive prop to single-thread export path or expose threshold in UI.


14. Conversation API: deleteConversations Returns null on Partial Failure

File: src/lib/conversation-api.ts (search for deleteConversations) — not fully read but based on client.ts:436-452
Evidence: fetchDeleteJsonOrNull returns null on 404/405. deleteConversations in HTTP client returns null if envelope missing (line 449-451). Caller cannot distinguish "all deleted" from "some missing".
Impact: Batch delete UX cannot show which IDs succeeded/failed.
Fix: Always return DeleteConversationsResult with results array and missingIds, even on HTTP 404.


15. Cursor Recovery: recoverCursorWorkspaceGroup Backs Up Target Bucket After Merging

File: src/lib/cursor-recovery.ts:328-332
Evidence: currentBucketData = readTargetBucketComposerData(target) (line 328) runs after merged is computed (lines 319-322). If readTargetBucketComposerData throws, no backup is made but backupComposerHeaders already ran (line 329).
Impact: Partial backup state on failure.
Fix: Read and backup target bucket before computing merged state.


🟢 Low Severity / Maintenance

16. Concurrency Limiter: mapWithConcurrency Stops All Workers on First Failure

File: src/lib/concurrency.ts:16-36
Evidence: failed flag (line 14) causes all workers to exit loop (line 17). Promise.allSettled then throws first failure (lines 29-35). Other in-flight mappers are abandoned without awaiting.
Impact: Resource leaks if mappers hold file handles/connections. No partial results returned.
Fix: Allow mapWithConcurrency to collect partial results via an option, or document that it's fail-fast only.

17. Download: revokeObjectUrl Called After Fixed Delay Regardless of Download Completion

File: src/ui/lib/download.ts:347-365 (downloadTextFile)
Evidence: schedule(() => revokeObjectUrl(url), revokeDelayMs) (line 359) uses 30s default. If download takes >30s (large file, slow network), URL is revoked mid-download.
Impact: Failed downloads for large inline exports.
Fix: Revoke on load/error event of the anchor or use URL.revokeObjectURL in a setTimeout with a much larger delay (5min).

18. Codex Rollout Snapshot: inode Comparison Fails on Network Filesystems

File: src/lib/codex-rollout-snapshot.ts:99-106 (isSameIdentity)
Evidence: Compares inode, ctimeMs, mtimeMs, sizeBytes. On NFS/SMB, inode may not be stable or meaningful.
Impact: False mutation detection on network drives.
Fix: Make inode comparison optional (skip if 0 or unavailable), rely on mtimeMs + sizeBytes.

19. Cline DB: isSafeClineSessionId Pattern Too Restrictive

File: src/lib/cline-exporter-types.ts:13-15
Evidence: /^[\p{L}\p{N}_-]+$/u excludes ULIDs (which contain lowercase letters and hyphens — actually allowed), but may exclude valid session IDs with other Unicode categories.
Impact: False negatives on valid session directories.
Fix: Align with actual Cline ID generation (likely UUID/ULID). Use ^[a-zA-Z0-9_-]{1,255}$ or similar.

20. Test Coverage: No Integration Tests for Cursor Workspace Deletion Rollback

File: src/lib/cursor-recovery.test.ts (referenced in AGENTS.md)
Evidence: AGENTS.md mentions tests for "Cursor recovery/prune behavior" but the deleted workspace flow (deleteCursorWorkspaceBuckets, deleteCursorWorkspaceHistory) involves FS + multi-DB transactions not covered by unit mocks.
Impact: Regression risk on FS permission changes, symlink attacks, concurrent Cursor writes.
Fix: Add a Vitest integration test with a temp Cursor-like DB structure, verifying rollback on injected failures.

Actionable Issues (Ordered by Severity)

Severity 1: Critical - Concurrency & Transaction Safety

1. src/lib/cursor-db.ts:92-123 - withCursorWriteTransaction race condition

  • Evidence: transactionStarted flag set inside callback; if callback throws before setting it, rollback is skipped. db.close() in finally can throw and mask original error.
  • Impact: Partial database writes on concurrent access; silent data corruption.
  • Fix: Track transaction state before callback entry; use more robust try/catch/finally pattern with error preservation.

2. src/lib/cursor-recovery.ts:336-347 - recoverCursorWorkspaceGroup rollback gap

  • Evidence: backupComposerHeaders and backupTargetBucketComposerData run before the write transaction. If transaction fails and rollback succeeds, bucket data on disk may be inconsistent with global DB state.
  • Impact: Inconsistent Cursor workspace state after recovery failure; threads may be lost or duplicated.
  • Fix: Perform backups inside the transaction or add compensating writes in the catch block.

3. src/lib/cursor-recovery.ts:530-541 - pruneCursorThreads ordering issue

  • Evidence: pruneWorkspaceBuckets (bucket mutations) runs before pruneGlobalThreads. If global transaction fails, bucket rollback may also fail, leaving inconsistent state across databases.
  • Impact: Partial deletions across global DB and bucket stores; some threads deleted from global DB but still in buckets.
  • Fix: Reverse order - prune global threads first, then buckets; or use two-phase commit pattern.

Severity 2: High - Schema/Compatibility Brittleness

4. src/lib/codex-rollout-snapshot.ts:99-106 - isSameIdentity relies on unstable inode

  • Evidence: inode field from stat() is NOT stable across network mounts, some cloud filesystems, and Docker volumes.
  • Impact: False mutation detection (export fails unnecessarily) or missed mutations (export proceeds with stale data).
  • Fix: Add modification time + size as primary comparison; use inode only as secondary confirmatory check.

5. src/lib/antigravity-keychain.ts:33-36 - Fixed cryptographic parameters

  • Evidence: SAFE_STORAGE_SALT = 'saltysalt', ITERATIONS = 1003, KEY_LENGTH = 16, zero-filled IV. These are hardcoded and could become obsolete/insecure.
  • Impact: Decryption failures if Keychain was created with different parameters; potential security vulnerability with weak IV.
  • Fix: Make salt/iterations configurable; use random IV stored with ciphertext; add version byte to encrypted payload.

6. src/lib/cursor-db.ts:337-343 - readBucketComposerIds swallows errors

  • Evidence: try/catch returns [] on any error, silently hiding missing databases, permission issues, or corrupted data.
  • Impact: Missing composer IDs; threads not discovered; no error indication to caller.
  • Fix: Log warning on error; or re-throw as specific error type that callers can catch.

Severity 3: Medium - Edge Cases & Missing Validation

7. src/ui/lib/download.ts:130-157 - createDownloadCancellation state sync race

  • Evidence: activeController and cancellationRequested flag can get out of sync. cancel() sets cancellationRequested = true then aborts, but begin() checks cancellationRequested after aborting previous controller - race window exists.
  • Impact: Cancellation not propagating; download continues after cancel request; signal lifecycle mismanagement.
  • Fix: Use atomic state reset; or simplify to single AbortController without the flag.

8. src/ui/lib/download.ts:242-269 - waitForDownloadUrlAvailability insufficient retries

  • Evidence: Max 6 attempts with fixed 250ms delay (total ~1.5s). No exponential backoff. CI/slow networks will fail prematurely.
  • Impact: Legitimate downloads fail with "was not available after 6 attempts" error.
  • Fix: Implement exponential backoff (250ms, 500ms, 1000ms, 2000ms, 4000ms, 8000ms) or make retry configurable.

9. src/lib/cursor-recovery.ts:648-654 - Hardcoded concurrency in pruneTranscriptDirs

  • Evidence: mapWithConcurrency(4, ...) with hardcoded value 4. No configurability for different deployment environments.
  • Impact: Too many concurrent file deletions may hit OS limits; too few wastes time on many small transcripts.
  • Fix: Make concurrency a parameter with reasonable default.

10. src/lib/cursor-db.ts:390-398 - writeTargetBucketComposerData returns void

  • Evidence: Uses withCursorWriteTransaction but returns undefined; callers can't detect write failure.
  • Impact: Write failures silently ignored; inconsistent bucket state undetected.
  • Fix: Return result from transaction; or throw on failure.

Severity 4: Medium - Error Handling Gaps

11. src/lib/cursor-db.ts:125-131 - withCursorWriteTransaction swallows close errors

  • Evidence: db.close() in finally throws caught and only logged via console.warn; original error re-thrown.
  • Impact: Database file handles may not be released on error; resource leak.
  • Fix: Ensure db.close() doesn't throw; or use try/catch that preserves original error.

12. src/lib/antigravity-keychain.ts:118-121 - Only 2 key derivation attempts

  • Evidence: Only tries plain secret + base64-decoded secret. Missing other possible encodings (hex, uppercase, etc.).
  • Impact: Decryption fails for valid Keychain entries stored with different encoding.
  • Fix: Attempt multiple common encodings or report which encoding was tried.

13. src/lib/cursor-db.ts:138-141 / 156-171 - Duplicated readItemValue/readKvValue patterns

  • Evidence: Identical try/catch/JSON.parse pattern repeated in two functions.
  • Impact: Maintenance burden; easier to introduce bugs in one branch.
  • Fix: Consolidate into single generic function with key table parameter.

Severity 5: Low - Maintainability & DX

14. src/lib/cursor-db.ts:687-695 - DISCOVERY_TTL_MS cache with no external invalidation guarantee

  • Evidence: 60s cache TTL; invalidateCursorDiscoveryCache exported but no compile-time guarantee callers remember to use it.
  • Impact: Stale workspace discovery results; UI shows outdated thread lists.
  • Fix: Add type documentation; or use a more robust caching strategy with version tracking.

15. src/lib/cursor-db.ts:156-171 - decodeCursorUri limited URI support

  • Evidence: Only handles file:// prefixed URIs. Other URI formats (http:, data:, etc.) not supported.
  • Impact: URI decoding fails for non-Cursor URIs; unexpected behavior in query matching.
  • Fix: Add fallback that returns raw URI; or document supported formats explicitly.

16. src/lib/cursor-recovery.ts:648-654 - pruneTranscriptDirs lacks error propagation

  • Evidence: rm(dir, { force: true, recursive: true }) errors silently; result.transcriptDirsRemoved set to total count regardless.
  • Impact: Some transcript dirs not actually removed; misleading deletion report.
  • Fix: Track actual successes/failures; return per-dir results.

17. src/ui/lib/download.ts:85-107 - delay function signal race

  • Evidence: If signal already aborted when delay() called, immediately rejects, but event listener may not be properly set up.
  • Impact: Download cancellation may not work reliably from the start.
  • Fix: Reorder: set up event listener before checking aborted state.

18. src/lib/cursor-db.ts:693-695 - invalidateCursorDiscoveryCache TypeDoc gap

  • Evidence: Function exported but no JSDoc explaining when it must be called (after any DB/bucket mutation).
  • Impact: Callers may forget to invalidate cache, showing stale data.
  • Fix: Add JSDoc with usage contract; or use a more automatic invalidation mechanism.

Summary: The top 3 issues are critical transaction/concurrency bugs that could cause data corruption. The next 3 are compatibility/safety issues that could cause export failures or data loss. The remaining issues are maintainability improvements.
