Cape Cod Patch v1.0

The Cape Cod Patch — a small, reversible, backup-first balance patch for X-COM: Terror from the Deep. 🦞

Patcher + docs only. This release ships no game files — cape_cod_patch.py edits a copy of the game you already own.

What it fixes

• Hidden Lobster Man resistances (Phase 1, default): the undocumented pre-armor damage discounts — 20% from guns, 30% from Gauss/explosives, 50% from Sonic — normalized to 100%. This alone is a 2×–5× increase in damage dealt to Lobsters.
• Toughness trim (--with-armor-hp, opt-in): modest Lobster armor + health reduction.
• Weak-hit lethality (--with-weapon-power, opt-in): Sonic Pistol clip power 80 → 66 so a minimum roll no longer one-shots a fresh 40-HP rookie.

Usage

```
python3 cape_cod_patch.py # Phase 1 (recommended)
python3 cape_cod_patch.py --full # everything
python3 cape_cod_patch.py --dry-run # preview
python3 cape_cod_patch.py --revert # undo
```

Safety

Verify-before-write (aborts on any unexpected build), automatic *.capecod.bak backups, idempotent re-runs, and byte-perfect --revert.

See CAPE_COD_PATCH.md for the full changelog, resistance table, and damage math.
