Complete Token Creation Fixes and TestingPublic

The user aimed to process the next set of tasks related to simple token creation in a game engine. They reviewed relevant files, identified cards needing fixes, applied changes to create tokens properly, added tests, and ensured all tests passed successfully. Documentation and tracking files were updated to reflect the completed work and findings.

Read docs/work-queue.md and do the next unchecked batch. For each batch:

Read the engine files (mtg-engine/src/abilities.rs, mtg-engine/src/game.rs) to understand current Effect/StaticEffect variants
If the batch has a NOTE about uncertainty, investigate first and update the queue with findings before committing the fix
If engine work is needed: add the variant, constructor, and match arm, and look for the Java implementation to see the bigger picture
Add a test for any new engine effect (follow the pattern in game.rs mod tests)
Fix all cards listed in the batch (grep to find exact lines, fix across all 4 set files)
cargo check -p mtg-cards && cargo test --lib
Update docs: mark cards in docs/{fdn,tla,tdm,ecl}-remediation.md, update ROADMAP.md
Check off the batch in docs/work-queue.md with today's date
If you discover new cards that fit the current or a future batch while working, add them to the queue

If a batch turns out to be wrong or more complex than described, update the queue with what you learned and move on to the next one.

I'll start by reading the work queue to find the next unchecked batch.

The next batch is Batch 4: Simple token creation. Let me start by reading the engine files and investigating the specific cards.

Let me read the full grep output and the CreateToken implementation in game.rs.

Let me check the parse_token_stats function and identify the card names for each line.

Let me read the remaining cards I need to identify.

Good. I have a clear picture now. Let me check for existing token creation tests.

No token creation tests exist yet. Let me look at the test patterns in the framework and game.rs test module.

Now I have a complete picture. Let me execute the batch:

Fixable cards (simple Custom(...) → create_token(...)):

FDN: Guarded Heir, Prideful Parent, Resolute Reinforcements, Release the Dogs, Dwynen's Elite, Dragonmaster Outcast, Searslicer Goblin (7 cards)
ECL: Clachan Festival (2 effects + 1 cost fix)

Skipping:

Food tokens (Cat Collector, Mender's Bounty) — artifact tokens, not creature. Needs engine change.
Faebloom Trick — compound effect (tokens + reflexive trigger tap)

Let me make all the edits and add a test.

Now the ECL fixes:

Good. Now let me add a test for CreateToken in the framework and verify the changes compile.

Now let me check if there's a has_keyword method on Permanent, and compile.

mtg-cards compiles. Now let me run the tests.

All 19 tests pass including the 2 new token creation tests. Let me also verify the full test suite passes.

All 249 tests pass (52+18+160+0+19). Now let me update the docs. Let me read the remediation docs to mark the fixed cards.

Only Clachan Festival is listed in the remediation docs. The other FDN cards weren't individually listed (they're probably lumped in a category). Let me update the Clachan Festival entry and add notes for the FDN cards.

Now let me check if the FDN cards are somewhere in the "broken" section. Let me look at the overall structure of the FDN remediation doc.

Now let me update the ROADMAP.md.

Now let me update the work queue — check off batch 4 and update it with findings.

Now let me update the batch 4 section.

Let me verify everything is clean with a final test run.

All 249 tests pass, compilation clean. Let me verify the actual edits look correct by spot-checking a couple.

All edits look correct. Let me do a quick summary of what was done:

Batch 4 complete. Here's what was done:

Cards fixed (8 cards, 10 Custom(...) → create_token(...) swaps):

Card	Set	Change
Guarded Heir	FDN	ETB → `create_token("3/3 Knight", 2)`
Prideful Parent	FDN	ETB → `create_token("1/1 Cat", 1)`
Resolute Reinforcements	FDN	ETB → `create_token("1/1 Soldier", 1)`
Release the Dogs	FDN	Spell → `create_token("1/1 Dog", 4)`
Dwynen's Elite	FDN	ETB → `create_token("1/1 Elf Warrior", 1)`
Dragonmaster Outcast	FDN	Upkeep → `create_token("5/5 Dragon with flying", 1)`
Searslicer Goblin	FDN	End step → `create_token("1/1 Goblin", 1)`
Clachan Festival	ECL	ETB → `create_token("1/1 Kithkin", 2)` + activated `Cost::pay_mana("{4}{W}")` + `create_token("1/1 Kithkin", 1)`

Tests added: framework_create_token_effect, framework_create_token_with_keyword

249 tests passing (52 + 18 + 160 + 0 + 19).

Deferred: Food tokens (artifact, not creature — needs engine change), Faebloom Trick (compound effect), all token copies, variable-count tokens. These findings are documented in the work queue.
