+# Balance Patch Notes v27.14
+
+## Event system
+
+The old shipment-goal terminology has been replaced by one-day Events in player-facing UI and balance notes. Internal names are mostly event-based; a few generic helper concepts are preserved only where they are not player-facing.
+
+Events start appearing from Day 8 with a 10% chance. An offered event is forced and applies only to the next running day.
+
+Implemented events:
+
+1. Premium Female Shipment
+   - Female -> Truck event.
+   - Target = estimated total production x 0.3.
+   - Success pays an event bonus.
+
+2. Contaminant Sample Export
+   - Poop is valid Truck cargo.
+   - All poop income is doubled.
+   - Target = estimated total production x 0.3.
+   - Success pays an event bonus.
+
+3. Health Inspection
+   - Poop mistake fines are doubled.
+   - Shredding enough poop pays an event bonus.
+
+4. Conveyor Jam Warning
+   - Jam explosion threshold becomes 85% congestion.
+   - Finishing with zero explosions pays an event bonus.
+
+5. Power Saving Order
+   - Conveyor speed x0.8.
+   - Auto Scanner cooldown x1.2.
+   - Settlement pays a flat subsidy.
+
+6. Overtime Day
+   - Day length becomes 80 seconds.
+   - No extra effect.
+
+7. Short Shift
+   - Day length becomes 40 seconds.
+   - Next Fairies tribute is reduced by 10%.
+
+8. Chick Boom
+   - Egg interval x0.65.
+   - Poop rate +5 percentage points.
+
+9. Rotten Feed
+   - Poop rate +20 percentage points.
+   - Shredder poop payout x1.5.
+
+10. Maintenance Audit
+    - No penalty.
+    - If no maintained machine is below 50% remaining durability, settlement pays a bonus.
+
+## Related balance behavior
+
+- Shredder Upgrade payout is affected by Event poop/shredder multipliers.
+- COMPOSTER payout is also affected by Event shredder payout multipliers.
+- Poop target Truck events no longer fine poop when poop is the valid cargo.
+- Chemical Weapons Subsidy remains 70 poop / 1200 yen.
+- Fairies tribute is paid on Next Day press.
+- Normal Loan card and repayment state are removed. Emergency Loan remains.
+- The old tax system is removed. Fairies tribute is the only recurring day-start levy.
+
+## v27.14 consistency/debug changes
+
+- Debug UI restored intentionally for balancing builds. HTML/CSS/JS include comments stating it should not be removed during cleanup unless explicitly requested.
+- Debug card selector is grouped by gameplay genre.
+- Debug single-card grant supports selecting the target for target-consuming build-phase cards.
+- Debug All Cards still uses automatic valid targets.
+- Removed unused special weight logic left over from old SPARE PARTS BIN behavior.
+- Removed unused Egg Farm cash upgrade cost data; Egg upgrades are card-based.
+- Shredder Upgrade now sums upgrades across all Shredder facilities, not only the original primary Shredder.
+- Maintenance and repair target collection now includes additional Mixer/Shredder facilities.
+- Maintenance Audit low-durability checks now include additional Mixer/Shredder facilities.
+- Fixed duplicate Emergency Loan button in the bankruptcy decision modal.
+- Fixed stale debug-removal CSS fragments left from the previous audit pass.
+- Fixed corrupted score-breakdown formula text.

 - Build, move, box-select, sell, and repair factory equipment during Build phase.
 - Start the next day only when at least one EGG route reaches a scanner and then any valid exit.
- Fairies tribute is paid after day-end settlement and before the next Build phase.
- Bankruptcy is checked only at that day-end transition. Temporary negative cash during production does not immediately end the game.
+- Fairies tribute is paid when pressing Next Day, using the previous day's net profit as part of the calculation.
+- Bankruptcy is checked at day-end settlement after shipment/event/subsidy revenue. Temporary negative cash during production does not immediately end the game.
 - Cards use English names and descriptions with numeric effect summaries.
 - `poop.png` is the only bundled image asset currently used by default; other art falls back to canvas drawing.

 ## Cleanup in this build

 - Removed duplicate `src/index.html` and `src/styles.css`; root `index.html` and `styles.css` are the single launch surface.
- Removed the old debug panel, debug hotkey, debug event log, and free-upgrade/debug-cash code.
+- Debug panel is intentionally present for balancing builds. Do not remove it during cleanup unless explicitly requested. Its card menu is grouped and target-consuming cards can be applied to selected targets.
 - Removed the obsolete right-side selected-facility panel code left behind after the UI removal.
 - Removed stale historical README files and old changelog text that no longer matched the current specification.
