Phase 4: Cobblebase and Poke Power, gated behind progression

Adrian (2026-10-30): Cobblebase's skills stay in but gated behind
progression, power from an existing mod (Poke Power) also gated,
evolution stones as ores fine for now, balance fine and configurable.

Progression is the zones whose Alpha guardian a player helped beat
(Progress saved data; a guardian win records it and lists the unlocks).
The gate table is data (progression_gates/base.json): each of
Cobblebase's 44 skills needs a zone (or none), the Power Block needs the
Verdant Jungle. The companion mod wraps every Cobblebase skill executor
in a gate by reflection; a skill missing from the table stays off.
Operator command /cobblesurvival progress. Cobblebase's and Poke Power's
configs ship in the pack. Self-tests: gate coverage, a locked skill only
runs after its guardian, the Power Block waits for the Jungle guardian,
a guardian win counts as progress.

 - Cold Sweat's own animals (chameleons) can't join, like vanilla mobs: the only-Pokémon rule now lets in Cobblemon's entities only.
 - Tested on the island itself (`cold_needs_fur`, `heat_needs_hide`, `lowlands_are_mild` in `tools/quick_check.py`): players stand at real spots in each zone, their body drift is turned into minutes until it hurts, and a frozen player without the grace period takes damage.

+**Adrian's answers (2026-10-30):** Cobblebase's skills look fun and stay in, gated behind progression; power comes from an existing mod, also gated (Cobblemon Poke Power); evolution stones as ores are fine for now; the balance values are fine for now and stay configurable, to tweak later.
 
 **Ore veins.** Ore only comes from [Regenerating Ore Veins](https://www.curseforge.com/minecraft/mc-mods/regenerating-ore-veins) (plus chest loot): a mined vein block turns into a regenerator and grows back after its time, which counts in real time, unlike the guardians' game time. Each ore tier has veins in exactly one zone, higher tiers in higher zones (table in `docs/balance.md`). `tools/zone_ores.py` writes the mod's config (`pack/config/regenerating_ore_veins/`) from `world/zones.json` → `ores`:
 
 - A surface zone is a set of boxes cut from the zone grid; the mod checks every block of a vein against them, so no vein block lies outside its zone. Cave biomes are zones of their own, so surface tiers stay out of them; the mod checks the biome only at a vein's centre, so a vein's edge can reach up to two blocks over a cave border. Cave tiers are limited to their cave biome and the depths where it lies (the Deep Dark mostly below y −24, the others between 0 and 40).
 - Tiers with an ordinary and a deepslate ore get two veins: the ordinary ore from y 0 up, the deepslate one below.
-- **Cobblemon's evolution stones are tiers too** (new in Phase 4, flagged): their natural ores have been off since Phase 1, so stones had no source. Each stone lives in one zone that fits it (Leaf Stone in the jungle, Water Stone in the Mire, Ice and Dawn Stone on Frostpeak, ...).
+- **Cobblemon's evolution stones are tiers too** (approved for now, 2026-10-30): their natural ores have been off since Phase 1, so stones had no source. Each stone lives in one zone that fits it (Leaf Stone in the jungle, Water Stone in the Mire, Ice and Dawn Stone on Frostpeak, ...).
 - Players can't break regenerators (`allow_breaking` false), so nobody removes a vein for good, and explosions don't hurt veins. The Vein Locator is crafted from a compass and a copper ingot instead of netherite.
 - The mod fills a new chunk with veins only while the chunk is loaded, 8 chunks a tick, and forgets the rest when the server stops. Pregeneration is faster than that, so `tools/make_world.py` loads the island again row by row until every chunk is filled (`/cobblesurvival veins unfilled` counts what's left), and the world report fails on any unfilled chunk. On a live server new chunks fill as players load them.
 - One showcase vein per surface zone (its first tier) sticks out of the ground near the zone's sample point, so players see what a vein looks like before they dig.

 **Unique drops.** Only Pokémon live on the island, so a mob's drop needs another source. `tools/drop_audit.py` checks every item a Pokémon or a vanilla mob drops that a recipe or brewing consumes, and writes `docs/pokemon-drops.md` (item, wild Pokémon with zone and chance, other sources, consumers). Gaps it found, filled through Cobblemon species additions (`datapacks/core/data/cobblesurvival/species_additions/`, placeholders): Blaze Rod (Carkol in Westmarch, Torkoal in the Basalt Furnace; needed for brewing stands, blaze powder and Eyes of Ender), Ghast Tear (Drifloon, Dusclops), Breeze Rod (Whimsicott), Shulker Shell (Shuckle, Cloyster), Nether Star (Charizard). The tide armour trim and the wither skeleton skull stay without a source (cosmetic here). A zone spawn with its own drops overrides the species' drops, so the audit also fails if an addition targets such a spawn (Magmortar's and Centiskorch's did). Self-test: `drop_additions_apply`.
 
+**Base jobs and power, gated behind progression.** A player's progression is the zones whose Alpha guardian they have helped beat (`progress/Progress.kt`, saved with the world; the guardian win records it for every player in the battle and lists what it unlocked). The gate table is data, `datapacks/core/data/cobblesurvival/progression_gates/base.json`:
+
+- [Cobblebase](https://modrinth.com/project/cobblebase) (Pokémon in a pasture work: harvesting, producing, finding, buffs, ...): each of its 44 skills works for a pastured Pokémon only once the Pokémon's owner has beaten the skill's zone. From the start: gathering, farming, producing, fuel, guarding, scouting; then step by step through the zones, with mining and the ore finder after Westmarch, the evolution-item finder after the Jungle, the player buffs after Highland Meadows and the Mire, the recruiter after Sunscorch and the healer after Frostpeak (table in `docs/balance.md`). The companion mod puts every Cobblebase skill executor behind the gate, by reflection, when the server starts (`progress/CobblebaseGate.kt`); a skill missing from the table stays off, so an update can't add ungated skills. Cobbreeding is not installed, so Breeder and Egg Hatcher do nothing.
+- [Cobblemon Poke Power](https://modrinth.com/project/lIn7oRFm) (Electric-type Pokémon in a Power Block make Forge Energy): a survival player can place a Power Block only after beating the Verdant Jungle's guardian (the zone with the redstone its recipe needs). Its recipe is the mod's own (iron blocks, redstone blocks, an Electirizer); nothing in the pack uses the energy yet (Phase 6 machines).
+- Operators: `/cobblesurvival progress <player>`, `... grant|revoke <player> <zone>`.
+- Self-tests: `gates_cover_every_cobblebase_skill` (every skill has a gate, every gate zone has a guardian, every executor is gated), `cobblebase_skills_wait_for_guardians` and `power_block_waits_for_guardian`; `guardian_appears_and_returns` checks that the win counts as progress.
+
 The field guide learned two things on the way: vanilla mobs count as absent (the companion mod lets only Cobblemon's entities join a world), and species additions replace the drops they set. The veins come in as sources from `world/vein-sources.json`.
