## Lifecycle ledger
- [lifecycle-events.jsonl](./lifecycle-events.jsonl)
- [ownership.md](./ownership.md)
- [worker-invocations.json](./worker-invocations.json) — report schema v2 append-ready worker payloads; unavailable token telemetry null.

## Wait/wakeup ledger
- [wait-wakeup-events.jsonl](./wait-wakeup-events.jsonl): managed bounded pool 4 requested/accepted/terminal/collected; max2 concurrent; 0 list/interrupt/recovery.

## Bash 단계 (advisor 직접)
- Read-only git diff/status and source contract inspection, artifact ledger/report serialization. No tests/build/runtime/DB/commit/push executed.
- update_plan unavailable for advisor/workers; bind not fabricated.

## 설계와의 차이
- Existing JSP uses separate edit attributes, so approved editDisplayWidth/Height/Source naming replaces hypothetical editModel object.
- Uploaded JavaScript style-variable assignments conservatively omitted; literal CSS, adjacent build-info, canvas attrs supported, manual override covers unknown templates.
- Added actual isolated MyBatis mapper contract test to requested docs/harness worker scope before writing.
- Coherent backend/frontend groups allocated explicitly; disjoint files, schema-only migration worker, fourth code-writer for docs/harness.

## Verification 을 위한 힌트
- Run `bash scripts/verify-webgl-display.sh all` (full offline Maven tests, Node tests, WAR package, disposable PostgreSQL migration/mapper contract).
- L2 requires local postgres:16 image and Docker daemon; override WEBGL_CONTRACT_POSTGRES_IMAGE to local compatible image, no auto pull.
- Runtime/auth/JSP/actual ZIP commands: docs/usage/webgl-display.md. Root has Chrome tools for isolated browser smoke.
- Test matrix: WebglDisplayMetadataTest, GameDisplayMetadataTest, GameUploadControllerSecurityTest, WebglDisplayDatabaseContractTest, src/test/js/webgl-player.test.cjs.
- No compile/test success claimed; unused automated gate unperformed because tools unavailable.
- Original ZIP/served uploaded HTML untouched.
