Summary
Complete rename of the card progression system from "Evolution" to "Refractor" — baseball card collecting terminology that matches the tier names (Base Chrome, Refractor, Gold Refractor, Superfractor).

Correctness
All model class renames are consistent:
EvolutionTrack→RefractorTrack,EvolutionCardState→RefractorCardState,EvolutionTierBoost→RefractorTierBoost,EvolutionCosmetic→RefractorCosmetic. ORMtable_namevalues,ModelIndexreferences, andcreate_tables()call indb_engine.pyall updated correctly. Router prefix and tags inrefractor.pyupdated to/api/v2/refractor.main.pyimport andinclude_routercall updated. No logic changes introduced — pure rename confirmed.Security
No issues found. Auth patterns unchanged. No new data exposure.
Style & Conventions
MODERATE — Migration SQL missing
BEGIN;/COMMIT;and rollback section.migrations/2026-03-23_rename_evolution_to_refractor.sqlruns fourALTER TABLE RENAMEstatements without a transaction wrapper. The existing migration (2026-03-17_add_evolution_tables.sql) wraps everything inBEGIN;/COMMIT;and has a rollback section at the bottom — this is the established project convention.Without
BEGIN;/COMMIT;, if the third or fourth rename fails (e.g. name conflict from a botched partial migration), the first two are already committed and the tables are in an inconsistent state with no documented recovery path. The fix is two lines:Plus a rollback comment block:
MINOR —
initialize_card_evolutionfunction name not renamed.app/services/refractor_init.pystill exportsinitialize_card_evolution(line ~57 in the new file). The module was renamed torefractor_initand all class references updated, but this public function name still says "evolution".cards.pyimports it asinitialize_card_evolutionfromrefractor_init. The PR claims a complete rename but this function name is a leftover. Suggested rename:initialize_card_refractor.MINOR —
/teams/{team_id}/evolutionsroute andlist_team_evolutionsfunction not renamed.teams.pylines 1534–1535 still use the old naming (@router.get("/{team_id}/evolutions")/async def list_team_evolutions). This may be intentional (fewer breaking changes for bot clients) but is inconsistent with the stated "complete rename" and undocumented as an exception. If intentional, worth a comment in the PR.NOTE — Migration FK ordering comment is slightly misleading.
The migration comment says the renames "respect foreign key dependencies (referenced tables first, then referencing tables)" implying order is required. In PostgreSQL,
ALTER TABLE RENAMEdoesn't affect FK constraints since they track tables by OID internally — the order makes no functional difference. Not a bug, just potentially confusing.Suggestions
/teams/{id}/evolutionsURL is intentionally kept (to avoid a bot-breaking change) or was missed. If intentional, document it in the PR body.initialize_card_evolutionfunction name inrefractor_init.pyis the only remaining "evolution" symbol in the live code path — worth renaming for full consistency.Verdict: COMMENT
The rename is mechanically complete and correct. All model, router, service, seed, and test files are updated. 117 tests pass. The migration SQL deviates from the project's
BEGIN;/COMMIT;convention and lacks a rollback section, which is a deployment safety concern worth addressing before running against prod. The two naming leftovers (initialize_card_evolution,/evolutionsroute) are functional non-issues but leave the rename incomplete.Automated review by Claude PR Reviewer

Style & Conventions
MODERATE — Migration missing
BEGIN/COMMITand rollback sectionmigrations/2026-03-23_rename_evolution_to_refractor.sqlhas no transaction wrapper or rollback block. The project convention from2026-03-17_add_evolution_tables.sqlis:For this migration the rollback would be:
MINOR — Misleading FK ordering comment in migration
The comment "The table renames are performed in order that respects foreign key dependencies (referenced tables first, then referencing tables)" is incorrect for PostgreSQL
RENAME. PostgreSQL tracks FK references by OID, not table name, so rename order is irrelevant. The comment is harmless but misleading — worth removing or correcting.MINOR — Stale comment in
cards.pyline 225Should be "refractor state".
Suggestions
Verdict: COMMENT
The rename is complete, correct, and consistent. All test files, routes, function names, and imports are properly updated. Two minor nits (stale comment, misleading migration comment) and one convention gap (missing
BEGIN/COMMIT+ rollback in migration). None of these block merging — noting for awareness.(Posting as COMMENT per Gitea self-review restriction.)

app/routers_v2/cards.py:225:# WP-10: initialize evolution state for each new card (fire-and-forget). The word "evolution" appears in the comment while the actual function call below it is correctlyinitialize_card_refractor. Minor inconsistency — the comment could read "initialize refractor state" — but does not affect correctness..pytest_cache/v/cache/nodeidscontains a stale entrytest_list_team_evolutionsreferencing the old test name. This is an auto-generated cache file and will be overwritten on the next test run. No action needed.Suggestions
app/routers_v2/cards.py:225from "initialize evolution state" to "initialize refractor state" for full consistency, though this is not required to merge.Verdict: APPROVED
All three issues from the prior review are correctly resolved. The rename is complete across all application code — routers, services, models, seeds, tests, and the migration. The only remaining "evolution" occurrences outside of intentionally-preserved historical migration files are a single code comment and prose in test docstrings, neither of which affects runtime behavior. Tests passed (117 passed, 15 skipped per PR description). Safe to merge.
Note: Gitea does not allow the PR author to self-approve, so this review is posted as COMMENT rather than APPROVED. The verdict is APPROVED.
