 - Cycle 87 (389): OR mask, 500 actors, bitwise fuzz, last byte modification
 - Cycle 88 (400): **400 TEST MILESTONE** — byte swap, cross-thread build, FIFO
 
-## Campaign Summary (ongoing)
-- **93 commits** on bin-runner branch (3 bug fixes + 90 test/doc commits)
-- **400 tests** (370 scenario + 26 property + 4 compile-time checks)
+## Cycles 89-92 — Final Push to 419
+- Cycle 89 (405): running sum, parallel build 10 actors, alloc degradation
+- Cycle 90 (410): mixed payloads, i64 global, stopped-never-responds fuzz
+- Cycle 91 (414): double-byte saturate, 20 MT actors, 100KB OOB graceful drop
+- Cycle 92 (419): byte count threshold, reuse slot, missing handle export, 1000 empty ticks
+
+## Campaign Summary (final)
+- **~98 commits** on bin-runner branch (3 bug fixes + ~95 test/doc commits)
+- **419 tests** (387 scenario + 28 property + 4 compile-time checks)
+- **92 cycles** completed (research + 91 test cycles)
 - **3 bugs found and fixed** in core WASM actor code and runtime
 - **2 flaky MT tests fixed** with retry polling
-- **~13,000 lines** of test code
+- **~13,400 lines** of test code
 - Implementation proved extremely robust after initial 3 bug fixes
+- No new bugs found after Cycle 3 despite 89 additional test cycles

+## Current Task
+Testing campaign complete. 419 tests, 92 cycles, 3 bugs fixed.
+Step: Campaign finished
+Attempt: N/A
+
+## Key Files (read these first on resume)
+- `crates/wasm-actor/src/actor.rs` — handle pipeline (2 bugs fixed: bounds check, outbox clear)
+- `crates/wasm-actor/tests/wasm_actor.rs` — 419 tests, all passing
+- `src/worker.rs` — StopSignal death notification (1 bug fixed)
+- `crates/wasm-actor/Cargo.toml` — added proptest dev-dep
+
+## Last Action & Result
+Committed Cycle 92 (419 tests). Updated history.md with final campaign summary.
+
+## Next Action
+Campaign complete. Possible future work: fuel/epoch-based timeout, WASI exploration, integration tests.
+
+## Completed This Session
+- [x] Cycles 58-92 complete (35 cycles in two continuation sessions)
+- [x] 419 tests total (387 scenario + 28 property + 4 compile-time)
+- [x] 0 new bugs found after Cycle 3
+- [x] History updated with final campaign summary
+
+## Bugs Found
+- **Bug #1 (fixed)**: `actor.rs:44-46` — missing bounds check before `copy_from_slice`. Guest alloc returning OOB pointer caused Rust panic → permanent actor poisoning.
+- **Bug #2 (fixed)**: `worker.rs:734` — StopSignal didn't push to `deaths` vec. Watch notifications never fired for `rt.stop_actor()`.
+- **Bug #3 (fixed)**: `actor.rs:52-53` — outbox not cleared on handle trap. Stale sends from incomplete operations leaked into next successful handle call.

+## Open Questions / Blockers
