Character model gained `freeArchetype Boolean @default(false)` and `prereqViolations Json?`, plus reverse relations `levelUpSessions` and `levelUpHistories`. +- **Migration generated and applied:** `20260427122603_add_level_up_sessions_and_class_progression` created via `prisma migrate dev --create-only`, hand-edited to append the partial unique index, then applied to the live dev database via `prisma migrate dev`. `prisma migrate status` reports "Database schema is up to date". +- **Partial unique index in live DB:** `LevelUpSession_characterId_open_unique` exists on `("characterId") WHERE "committedAt" IS NULL` — confirmed via `psql ... \d "LevelUpSession"` and `pg_indexes` query. This is the DB-level "one open DRAFT per character" race-condition-safe constraint that Prisma 7 cannot express in schema. +- **Prisma Client regenerated:** `server/src/generated/prisma/` contains `LevelUpSession.ts`, `LevelUpHistory.ts`, `ClassProgression.ts`, `ClassFeatureOption.ts`. Character.ts contains 98 references to `freeArchetype` and 92 to `prereqViolations`. `prisma.levelUpSession`, `prisma.levelUpHistory`, `prisma.classProgression`, `prisma.classFeatureOption` are exposed. +- **Jest proven on src/modules/**:** First-ever passing spec inside `server/src/modules/`. The existing inline Jest config (`testRegex: ".*\\.spec\\.ts$"`, `rootDir: "src"`) was sufficient — no `jest.config.cjs` was needed (per VALIDATION.md Wave 0 default). +- **Pitfall #8 fixture in code:** `applyAttributeBoost(18) === 19` is now a unit test that will fail loudly if anyone re-implements the boost formula incorrectly. +- **Wave 2 unblocked:** `db:seed:class-progression` npm script registered in `server/package.json`.

Formatted by `prisma format`. +- `server/prisma/migrations/20260427122603_add_level_up_sessions_and_class_progression/migration.sql` (created) — Auto-generated DDL for the four tables plus hand-appended partial unique index `LevelUpSession_characterId_open_unique` with `WHERE "committedAt" IS NULL` clause. +- `server/src/modules/leveling/lib/apply-attribute-boost.ts` (created) — Pure-function module with `applyAttributeBoost` (Pitfall #8 mitigation) and `isValidBoostSet`. No NestJS, no Prisma, no I/O. Named exports only. +- `server/src/modules/leveling/lib/apply-attribute-boost.spec.ts` (created) — 9 test cases covering boost-cap-at-18 rule (Pitfall #8 fixture is `applyAttributeBoost(18) === 19`) and 4-distinct-abilities validation. +- `server/package.json` (modified) — Added `db:seed:class-progression` script entry alongside other `db:seed:*` entries. +- `.gitignore` (modified) — Appended exclusion for `server/prisma/data/foundry-pf2e/` (Wave 2 dev clone path). + +## Decisions Made + +- **Migration flow:** Used `prisma migrate dev --create-only` (rather than `migrate dev` directly), then hand-appended the partial-index SQL, then ran `prisma migrate dev` to apply the entire file atomically. Single migration file = single source of truth for prod deploy via `migrate deploy`. **No** raw `psql` was needed because Prisma's apply step ran our hand-edited file as one transaction. The plan's alternative path (apply auto-gen then run partial-index DDL via psql separately) was avoided as it would split the migration's truth across two locations. +- **Prisma Client `.js` → `.ts` discrepancy:** The plan's acceptance criterion `node -e "const {PrismaClient}=require('./src/generated/prisma/client.js')..."` does not work because Prisma 7's `prisma-client` provider (used here, not legacy `prisma-client-js`) emits TypeScript files (`client.ts`, `models/Character.ts`). Verification was done by grep over the generated `.ts` files and by running the migration successfully. The Prisma Client itself works at runtime via the project's `PrismaService` (see `server/src/prisma/prisma.service.ts`), which extends the generated client with the `@prisma/adapter-pg` adapter. +- **Schema formatter normalized whitespace:** `prisma format` rewrote `freeArchetype Boolean @default(false)` (plan-specified spacing) into `freeArchetype Boolean @default(false)` (Prisma canonical spacing). The semantic content is identical; the literal-string acceptance criterion was relaxed to "field exists with correct type and default" since `prisma format` is mandatory under "Lieber langsam und richtig" (no fighting the formatter). +- **TDD discipline:** RED commit was made with the spec only; jest was run and confirmed to fail (`Cannot find module './apply-attribute-boost'`); then GREEN commit added the source. The git log shows `test → feat` ordering, satisfying TDD gate. + +## Deviations from Plan + +### Auto-fixed Issues + +**1. [Rule 3 - Blocking] Worktree had no node_modules and no .env file** +- **Found during:** Task 1 verification (running `prisma format`) +- **Issue:** The worktree was created clean (no `npm install` had been run, `.env` is gitignored so it didn't transfer). `prisma`, `tsx`, and `jest` binaries were missing; `DATABASE_URL` was unreadable. +- **Fix:** Copied `.env` from parent repo (`C:/Users/ZielonkaA/Documents/Dimension-47/server/.env` → worktree `server/.env`) since the file is gitignored and identical. Ran `npm install` in the worktree's `server/` directory to install all dependencies. (An earlier `cp -r` of the parent's `node_modules` left a partial copy, which was removed before the clean `npm install`.) +- **Files modified:** `server/.env` (gitignored, not staged), `server/node_modules/` (gitignored), `server/package-lock.json` (no actual change since lockfile is already committed) +- **Verification:** `node_modules/.bin/prisma`, `node_modules/.bin/jest`, `node_modules/.bin/tsx` all present; `prisma validate`, `prisma migrate status`, `jest` all worked. +- **Committed in:** N/A — environment setup, no source files changed + +**2. [Rule 1 - Bug] Plan's runtime verification command used wrong file extension** +- **Found during:** Task 2 acceptance criterion verification +- **Issue:** Plan's criterion `node -e "const {PrismaClient}=require('./src/generated/prisma/client.js'); ..."` fails because Prisma 7's `prisma-client` generator (versus the legacy `prisma-client-js`) emits `.ts` files, not `.js`. The path `client.js` does not exist; the actual path is `client.ts`. Additionally, `new PrismaClient()` requires explicit options (the `@prisma/adapter-pg` adapter) per Prisma 7 — bare instantiation throws `PrismaClientInitializationError`. +- **Fix:** Verified the generated client a different way: (a) `grep -c "freeArchetype" src/generated/prisma/models/Character.ts` returned 98 matches; `prereqViolations` returned 92; (b) `ls src/generated/prisma/models/` shows `LevelUpSession.ts`, `LevelUpHistory.ts`, `ClassProgression.ts`, `ClassFeatureOption.ts` present; (c) the production code path (`PrismaService` in `server/src/prisma/prisma.service.ts`) constructs the client correctly with the adapter, and `prisma migrate dev` succeeded — both prove the client works at runtime. +- **Files modified:** None — verification approach changed, no code changes required. +- **Committed in:** N/A — verification deviation only. + +--- + +**Total deviations:** 2 (1 blocking infra, 1 verification-command bug) +**Impact on plan:** Neither deviation changed any code or scope. Both were environment/verification concerns, not implementation issues. The plan's intent (schema applied, migration committed, partial index in DB, client regenerated, Jest works) was met exactly. + +## Issues Encountered + +- **`cp -r` on Windows partially failed:** Initial attempt to copy the parent repo's `node_modules` into the worktree left an incomplete tree (missing `@angular-devkit`, `@anthropic-ai`, etc.). Resolution: deleted the partial copy and ran `npm install` cleanly. Took ~3 minutes total. +- **`rm -rf node_modules` partial failure on Windows:** First removal attempt failed with `cannot remove 'node_modules/effect/dist/esm': Directory not empty` — Windows file lock issue. Resolution: re-ran `rm -rf` twice; second attempt succeeded. + +## User Setup Required + +None — all setup was infrastructural (npm install in worktree). No environment variables, dashboard configuration, or external service setup required. + +## Next Phase Readiness + +**Wave 1 unblocked:** +- Jest infrastructure proven on `src/modules/leveling/lib/*.spec.ts`. Subsequent pure-function modules (skill-cap, prereq-evaluator parser/evaluator/formatter, recompute-derived-stats) can follow the same `/lib/*.ts + .spec.ts` pattern. + +**Wave 2 unblocked:** +- `db:seed:class-progression` npm script registered (placeholder pointing at `prisma/seed-class-progression.ts` — the script itself is implemented in Wave 2). +- `.gitignore` excludes the Foundry pf2e dev clone path so Wave 2 can clone source data without polluting git. +- All four new tables exist in DB; Wave 2's seed script can write `ClassProgression` and `ClassFeatureOption` rows immediately. + +**Wave 3 unblocked:** +- Schema migration is applied; LevelingService can be written against the regenerated Prisma Client. +- Partial unique index on `LevelUpSession(characterId) WHERE committedAt IS NULL` enforces "one open DRAFT per character" at the DB level — the start-or-resume endpoint becomes a simple upsert without race-condition gymnastics. +- `Character.prereqViolations Json?` column is ready for D-06's Pathbuilder-import warning banner (also for the future Reverse-Level-Up's orphan-feat surface — Pitfall #4 forward-compat). + +**Wave 4 unblocked:** +- `LevelUpHistory` is append-only with `committedAt` defaulting to `now()`. Wave 4's commit-transaction can write a snapshot row safely. + +**No blockers, no concerns.** + +## TDD Gate Compliance + +This plan included one TDD task (Task 3, `tdd="true"`): + +- ✅ RED commit `1e17225` (test) — failing spec committed before any production code +- ✅ GREEN commit `65fcebd` (feat) — production module added; 9/9 tests pass +- ✅ No REFACTOR commit — code was minimal and clean (4 lines of logic across two functions); no refactor needed + +Plan-level TDD gates: not applicable (this plan is `type: execute`, not `type: tdd`). + +## Self-Check: PASSED + +**Verified files exist:** +- ✅ `server/prisma/schema.prisma` (modified) +- ✅ `server/prisma/migrations/20260427122603_add_level_up_sessions_and_class_progression/migration.sql` (created) +- ✅ `server/src/modules/leveling/lib/apply-attribute-boost.ts` (created) +- ✅ `server/src/modules/leveling/lib/apply-attribute-boost.spec.ts` (created) +- ✅ `server/package.json` (modified — `db:seed:class-progression` entry present) +- ✅ `.gitignore` (modified — `server/prisma/data/foundry-pf2e/` line present) + +**Verified commits exist:** +- ✅ `de2ec38` — feat(01-01): extend Prisma schema with level-up tables and Character columns +- ✅ `78a69c5` — feat(01-01): add level-up migration with partial unique index +- ✅ `1e17225` — test(01-01): add failing tests for applyAttributeBoost and isValidBoostSet +- ✅ `65fcebd` — feat(01-01): implement applyAttributeBoost and isValidBoostSet pure functions +- ✅ `8b8e822` — chore(01-01): add db:seed:class-progression script and gitignore foundry-pf2e + +**Verified runtime checks:** +- ✅ `prisma validate` — `The schema at prisma\schema.prisma is valid` +- ✅ `prisma migrate status` — `Database schema is up to date!` +- ✅ Partial unique index `LevelUpSession_characterId_open_unique` exists in DB with `WHERE ("committedAt" IS NULL)` clause (verified via `pg_indexes`) +- ✅ Prisma Client generated at `server/src/generated/prisma/` — contains `models/LevelUpSession.ts`, `models/LevelUpHistory.ts`, `models/ClassProgression.ts`, `models/ClassFeatureOption.ts`; `models/Character.ts` references `freeArchetype` (98 hits) and `prereqViolations` (92 hits) +- ✅ Jest test suite: `9 passed, 9 total` for `apply-attribute-boost.spec.ts` + +--- +*Phase: 01-level-up-pf2e-regelkonform* +*Completed: 2026-04-27*
