Summary

finish() closure in extensions/feishu/src/async.ts:79 references timer, but timer is declared as const after finish is defined. If finish(false) fires via the abort signal at line 99-100 before const timer on line 103 executes, accessing timer in the temporal dead zone throws ReferenceError.

Reproduction

Source inspection: guaranteed TDZ violation path at lines 79-103. Currently guarded by the outer abortSignal?.aborted check, but fragile.

Expected

Hoist timer as let above finish so it is safely undefined when finish fires early.

Scope

extensions/feishu/src/async.ts:77-107 — 1 file, ~1 LoC change.
