RUMBO R4 — PR #392 Final Head Binding\n\nStatus: **TEST_ONLY_BINDING_PASS / MERGE_NOT_AUTHORIZED / PRODUCTION_NO_GO**\n\nThis record binds the live external R2 guard to the exact current GitHub PR #392 head without granting merge or production authority.\n\n## GitHub binding\n\n- repository identity SHA-256: `59e28afe0dd67d61cdaaaa5d470a6470b6c1540f025d172f094fe3321857fc23`\n- PR: `392`\n- base

`afbdc77510286adc5721ada5a0ddfa75e10305cb5200d6fd37cd8438c9c6119f`\n\nThe PR was observed OPEN, DRAFT, mergeable, with five changed files when the evidence object was constructed.\n\n## External runtime binding\n\nRuntime: `sebas1/rumbo-continuity-relay`\n\nImplementation observed before issuance:\n\n`R4-ACCEPTANCE-GUARD`\n\nRuntime guard state:\n\n- configured: true\n- merge authorization

branch-scoped script used the encrypted `R2_GUARD_TOKEN_V1` environment variable to call the live main runtime. The bearer and the raw one-time token were never logged.\n\nResult:\n\n- authorize: PASS\n- consume: PASS\n- one-time authorization ID: `6c54a26a-4cf3-4893-87ff-233c5351cc3d`\n- request SHA-256:

production_go: false\n\nVal Town evaluation ID:\n\n`01a04b5b-0efc-7728-8cc1-a86bd8d43430`\n\n## Safety audit\n\nThe runtime was independently re-audited before this transaction:\n\n- five guard routes present;\n- five guard routes require the dedicated guard bearer;\n- no raw guard bearer embedded in source;\n- merge authorization blocked at both issuance and consumption;\n- no public guard self-test route;\n- unauthenticated ledger access returns 401;\n- guard token hashes are not projected by ledger/status reads;\n- `production_go=false` remains invariant;\n- R4 acceptance verifier is read-only and currently reports `PENDING_CODEX_ACK`;\n- acceptance self-test returned PASS while preserving `production_go=false`.\n\nThe temporary PR-binding script was deleted from the release branch after its single successful execution.\n\n## Claim boundary\n\nThis record proves only that the external fail-closed authorizer could issue and atomically consume one TEST_ONLY authorization bound to the exact PR #392 head above.\n\nIt does **not** prove or authorize:\n\n- `MERGE_PR`\n- `GITHUB_OBSERVER_VALIDATED`\n- `DEDICATED_GITHUB_APP_CUSTODY`\n- `EXTERNAL_DEPLOYER_LIVE`\n- `PRODUCT_GO`\n- `PRODUCTION_GO`\n\nPR #392 must remain draft while the private GitHub-hosted observer is unable to obtain a runner and until the remaining trust-root gates are satisfied.\n",["D",1787970901574],"branchVersion","label",[18],"pulls","branches",26,"forks","envVars",{"_172":174,"_175":26},"connections",{"_172":26,"_173":26},"count","unfilledCount",21,"emptyCount",{"_32":234,"_13":235,"_68":236,"_42":-5,"_34":35,"_161":39,"_187":88,"_36":237,"_38":26,"_70":238,"_158":-5,"_71":24,"_162":-5,"_191":239,"_17":240},{"_32":227,"_13":228,"_68":229,"_42":-5,"_34":35,"_161":39,"_187":88,"_36":230,"_38":26,"_70":21,"_158":231,"_71":24,"_162":-5,"_191":232,"_17":233},{"_32":220,"_13":221,"_68":222,"_42":-5,"_34":35,"_161":39,"_187":88,"_36":223,"_38":26,"_70":21,"_158":224,"_71":24,"_162":-5,"_191":225,"_17":226},{"_32":157,"_13":18,"_68":69,"_42":-5,"_34":35,"_161":39,"_187":88,"_36":217,"_38":26,"_70":21,"_158":159,"_71":24,"_162":-5,"_191":218,"_17":219},{"_32":209,"_13":210,"_68":211,"_42":-5,"_34":35,"_161":212,"_187":88,"_36":213,"_38":26,"_70":21,"_158":214,"_71":24,"_162":-5,"_191":215,"_17":216},{"_32":202,"_13":203,"_68":204,"_42":-5,"_34":35,"_161":39,"_187":88,"_36":205,"_38":26,"_70":21,"_158":206,"_71":24,"_162":-5,"_191":207,"_17":208},{"_32":194,"_13":195,"_68":196,"_42":-5,"_34":35,"_161":39,"_187":88,"_36":197,"_38":26,"_70":198,"_158":199,"_71":24,"_162":-5,"_191":200,"_17":201},{"_32":184,"_13":185,"_68":186,"_42":-5,"_34":35,"_161":39,"_187":88,"_36":188,"_38":26,"_70":189,"_158":190,"_71":24,"_162":-5,"_191":192,"_17":193},"b3b25080-946b-4eb7-bd04-3c71e653ef4d","main.tsx","01a04b5e-d628-7300-9f10-20c6507670c8","latest",["D",1787970901574],"http","import
