In `@src/storage/mail.ts`:
- Around line 239-260: The JSON.parse in rowToHandoff can throw on malformed or
legacy data; update the rowToHandoff method to defensively parse row.context
(from HandoffRow) inside a try/catch, returning a safe fallback (e.g. null or an
empty object) for the context field on parse failure and optionally logging the
error, then return the Handoff object with acceptedAt and createdAt unchanged;
ensure rowToMail is left as-is unless it later contains JSON fields.
In `@src/storage/workitems.ts`:
- Around line 269-293: The dispatchBatch logic (dispatchBatch, using
this.storage.getDatabase(), listWorkItems, updateStmt, addEvent, and
updateBatchStatus) must be wrapped in a single DB transaction so all per-item
updates, event inserts and the final batch status change are atomic; refactor
dispatchBatch to create a transaction via db.transaction(), move the loop that
runs updateStmt and calls addEvent plus the updateBatchStatus(batchId,
'dispatched') call inside that transaction, ensure the transaction returns the
assigned count and that any failure rolls back so partial updates/events cannot
be left behind.
In `@src/workers/worktree.ts`:
- Around line 8-10: Several git/gh calls currently build shell-interpolated
commands with execSync (e.g., in create(), remove(), cleanupOrphaned(),
commit(), push(), createPR(), getStatus()) which is vulnerable to command
injection; replace each execSync usage with execFileSync or spawnSync and pass
the binary as the first argument and every dynamic value (workerId, branch,
message, title, body, base, file paths, flags) as elements of an args array so
the shell is not used, and remove any inline quoting/escaping logic; ensure to
set options.shell = false (default) and pass cwd where needed (e.g., repo dir)
and propagate stdout/stderr as before. Also apply the same change for any gh CLI
calls and validate file paths with path.join/existsSync before executing to
avoid unsafe inputs.

Guard JSON.parse to avoid crashing on malformed rows.
A corrupted row or older data could throw here and break retrieval. Consider a try/catch with a safe fallback or a controlled error.

Wrap batch dispatch in a transaction to ensure atomicity.
The current code loops through items, updating each and logging events, then marks the batch dispatched—but these operations lack atomicity. If an addEvent call fails mid-loop or updateBatchStatus fails silently, the batch can end up in an inconsistent state (work items updated but batch not marked, or vice versa). Use db.transaction() to wrap all assignments and the batch status update in a single atomic operation.

Use execFileSync with argument arrays instead of execSync with shell interpolation to prevent command injection.
execSync with interpolated variables (workerId, branch, message, title, body, base, and file paths) allows shell metacharacters to execute arbitrary code. The quote escaping at lines 215 and 271 is insufficient—backticks and other metacharacters still escape. Switch to execFileSync (or spawnSync) with argument arrays to pass all values safely without shell interpretation. Apply this pattern to all git/gh calls: create() (lines 63–78), remove() (lines 106–126), cleanupOrphaned() (lines 156–193), commit() (line 215), push() (line 242), createPR() (line 271), and getStatus() (lines 305–342).
