 - REQ-UI-DEBUG-OVERLAY: While debug draw mode is active (REQ-UI-DEBUG-DRAW), a text overlay is drawn in the upper left corner of the game world view. The overlay has a semi-transparent black background sized to fit its content. It displays the following lines of text:
   - `Accumulated Threat Level: <level>` — where `<level>` is the current accumulated threat level (see REQ-WAV-THREAT-RATE).
   - `Time until Wave: <time_s>` — where `<time_s>` is the remaining time in seconds on the normal-wave inter-wave gap timer (see REQ-WAV-GAP). During a quiet window the gap timer is frozen; the displayed value reflects that frozen state.
+  - `Threat Accumulation Rate: <rate> threat/s` — the rate at which the accumulated threat level is currently increasing (see REQ-WAV-THREAT-RATE). During a quiet window (REQ-WAV-QUIET), this is 0, reflecting that accumulation is currently paused.
+  - `Max Factory Production: <rate> threat/s` — the threat-equivalent of the factory's total possible production: 1 threat/second for each completed (operational, not under construction) miner, smelter, assembler, reprocessing plant, and shipyard. One second of production equals one threat (see REQ-MOD-THREAT).
+  - `Current Factory Production: <rate> threat/s` — the threat-equivalent of the factory's current production: 1 threat/second for each completed miner, smelter, assembler, reprocessing plant, or shipyard that currently has an active production cycle (see REQ-MAT-CYCLE; for shipyards, an in-progress production cycle per REQ-BLD-SHIPYARD).
