**NEXT:** rerank the final four gaps and investigate SYSTEM4's singleton `0x149`; keep developer-only
`0x24d` for its dedicated movie-mask compositor slice.
**SYSTEM-MENU SHOW DELAY `0x149` INVESTIGATION COMPLETE (2026-07-29):** the opcode replaces the unsigned
millisecond threshold at `EngineCtx.system_menu_show_delay_ms`; scene reset defaults it to zero and
SYSTEM4's sole call sets 1000. The exact, unobserved paired getter is opcode `0x148`.
AGE's Win32 window procedure starts a 100-millisecond timer while the pointer dwells in the top two client
rows. Once unsigned elapsed time is strictly greater than the configured threshold, with no mouse button
held, windowed ScreenMode, and no active AGERC host UI, it reveals AGERC's modeless full-width system-menu
strip. Alt reveals the same strip immediately and bypasses the threshold. This is the same settings/save
menu whose actions opcode `0x142` guards against CONFIG reentrancy, but it is unrelated to the adjacent
`0x248` graphics configuration.
The current Godot frontend has no equivalent application-menu strip. The bounded implementation is exact
state parity: retain the full unsigned dword, reset it to zero with scene context, implement the paired
getter, and expose it for a future host strip without changing game input, the script-authored right-click
menu, or persistence. This investigation changes metadata only, so the inventory remains 4 opcodes /
5 instructions. The `/v2` and `/support/AGERC.DLL` handlers, reveal/timer/dialog paths, typed EngineCtx
field, and key globals are annotated and saved.
**NEXT:** implement the exact `0x148`/`0x149` state pair. Afterwards rerank `0x137`, `0x241`, and the two
developer-only `0x24d` sites.
**SYSTEM-MENU SHOW DELAY `0x148`/`0x149` IMPLEMENTED (2026-07-29):** the VM now retains the complete
unsigned threshold, returns the same native dword through signed script integer cells, and restores zero
on root scene-context reload. SYSTEM4's 1000-millisecond setup is handled without inventing an `IHost`
effect for an AGERC strip the Godot frontend does not have.
Three focused regressions cover the exact SYSTEM4 setter/getter sequence, high-bit dword preservation, and
root-reload lifetime. The shipped setter site is closed; the unobserved getter is also available for
broader AGE compatibility. The remaining effectful inventory is 3 opcodes / 4 instructions. Validation
passes 501/501 engine tests, opcode and EngineCtx build/lint, a zero-warning Godot build, clean diff
checking, and the Himegari-targeted threaded `SELFTEST OK`.
**NEXT:** rerank `0x137`, `0x241`, and developer-only `0x24d` ×2 before choosing the next slice.
