binding to action, PR number, base/head SHA, package SHA-256 and evidence SHA-256;\n- one-time random token returned only at issuance;\n- only token SHA-256 persisted;\n- TTL 60–900 seconds;\n- duplicate exact request rejection;\n- atomic single consumption;\n- replay rejection;\n- token mismatch rejection;\n- binding mismatch rejection;\n- expiry/revoke states;\n- independent audit hash chain;\n- ledger and audit endpoints require the dedicated bearer;\n- token hashes are not projected by ledger reads;\n- `production_go=false` invariant.\n\n## Merge gate\n\n`MERGE_PR` is checked at both issuance and consumption.\n\nIt remains disabled because:\n\n`R2_ALLOW_MERGE_AUTHORIZATION`\n\nis intentionally absent.\n\n## Live adversarial test\n\nVal Town

The private key is not present in source or response payloads.\n\n## Receipt contract\n\nSuccessful `POST /v1/consume` now returns schema:\n\n`rumbo-r2-dedicated-authorizer-consumption/v2`\n\nThe signature covers the exact canonical receipt object, including:\n\n- authorization id;\n- action;\n- repository identity SHA-256;\n- PR number;\n- base and head Git SHA;\n- sealed package SHA-256;\n- evidence SHA-256;\n- request SHA-256;\n- consumed timestamp;\n- consumer;\n- merge-authorized state;\n- production-go state.\n\nThe response includes:\n\n- `receipt_sha256`;\n- `receipt_signature.alg=ES256`;\n- exact signing key id;\n- base64url signature.\n\n## Adversarial validation\n\nBranch evaluation:\n\n`01a04ba6-7c96-71ee-888f-953a2f36529f`\n\nResult: **PASS**.\n\nAdditional V2 checks:\n\n- signing key configured: true;\n- signed receipt verification: true;\n- modified receipt verification: false;\n- receipt SHA-256 recomputation: exact;\n- replay still rejected;\n- token hash still absent from read APIs;\n- audit chain valid;\n- `MERGE_PR` still disabled at issuance and consumption;\n- `production_go=false`.\n\nValidated test receipt SHA-256:\n\n`ea6091f0d05f4c5ddd6693728fe6ec41fa39bb627f4128a74fb1ebc597a60756`\n\n## Downstream consequence\n\nThe deployer no longer needs to trust an arbitrary caller-supplied\n`authorizer_receipt_sha256`. It can verify a signed consumption receipt offline using\nonly the pinned public key.\n\nThis closes the receipt-authenticity gap between authorization custody and deployment\nplanning. It does not enable merge or deployment.\n",[],[123],["D",1787978146169],[],[19],["D",1787974602620],"legacyEnvVars","httpPrivacy","description","Dedicated fail-closed RUMBO R2 authorizer","imageUrl","userId","d3788f19-13c5-4356-87e8-dce639626bb9","pinnedFileId","da1a7e96-a35a-11f1-816f-1607ee4eb77e","pinPreview","pinMigrated","screenshotVersion","likeCount","tursoName","c407813c3b2b489fa186e17f90eccf60","tursoHostname","c407813c3b2b489fa186e17f90eccf60-val-town.aws-us-east-2.turso.io","tursoMeasuredAt",["D",1789452068287],"pinned","userPerm","r","valPerm","blobPerm","rw","emailPerm","sqlitePerm","projectPerm","telemetryPerm","user",{"_11":12,"_179":175},"org",{"_11":12,"_172":173,"_174":175,"_138":139,"_176":177,"_178":52},"branch",{"_17":103,"_13":16,"_36":64,"_43":44,"_46":37,"_47":168,"_169":54,"_170":44,"_171":57,"_58":14,"_55":12},8,"forkedProjectPrivacy","forkedProjectId","forkedProjectOrgId","displayName","sebas","avatar","https://lh3.googleusercontent.com/a/ACg8ocJaC6uiXPmN9dvgA2XcSlzBSkPJO0GN5zKzPm3a8cbjmXC9HYA=s96-c","tier","free","canRestrictVals","profileImageUrl","adoptOrgId",{"_36":44,"_13":14,"_38":233,"_50":-5,"_133":52,"_53":54,"_134":54,"_135":136,"_137":-5,"_138":139,"_140":141,"_142":67,"_143":-5,"_144":-5,"_145":69,"_56":57,"_146":147,"_148":149,"_150":234,"_152":-5,"_153":154,"_155":154,"_156":157,"_158":157,"_159":157,"_160":154,"_161":154,"_162":235,"_164":236,"_166":237,"_51":52},[212,213,214,215,216,217,218],"files",[212,213,214,215,216,217,218],"counts",{"_203":69,"_204":34,"_205":69,"_35":206,"_207":208},[],{"_36":59,"_13":19,"_60":61,"_62":-5,"_63":64,"_65":32,"_66":67,"_38":68,"_17":69,"_70":24,"_71":72,"_73":52,"_74":-5,"_18":202},"upstreamProject","upstreamBranch",{"_36":37,"_38":200,"_40":201,"_13":42,"_43":44,"_17":45,"_46":-5,"_47":-5,"_48":49,"_50":-5,"_51":52,"_53":54,"_55":12,"_56":57,"_58":14},"emptyEnvVars","flags",[],"hasHttpFiles","grants","orgs","customDomains",{},["D",1787974602620],["D",1787988816758],[19],"pulls","branches","forks",{"_209":103,"_211":69},"connections",{"_209":69,"_210":69},"count","unfilledCount","emptyCount",{"_36":59,"_13":19,"_60":61,"_62":-5,"_63":64,"_65":32,"_66":67,"_38":129,"_17":69,"_70":24,"_71":72,"_73":52,"_74":-5,"_89":231,"_18":232},{"_36":122,"_13":123,"_60":124,"_62":-5,"_63":64,"_65":32,"_66":67,"_38":125,"_17":69,"_70":24,"_71":126,"_73":52,"_74":-5,"_89":229,"_18":230},{"_36":115,"_13":116,"_60":117,"_62":-5,"_63":64,"_65":32,"_66":67,"_38":118,"_17":69,"_70":24,"_71":119,"_73":52,"_74":-5,"_89":227,"_18":228},{"_36":108,"_13":109,"_60":110,"_62":-5,"_63":64,"_65":32,"_66":67,"_38":111,"_17":69,"_70":24,"_71":112,"_73":52,"_74":-5,"_89":225,"_18":226},{"_36":100,"_13":101,"_60":102,"_62":-5,"_63":64,"_65":103,"_66":67,"_38":104,"_17":69,"_70":87,"_71":105,"_73":52,"_74":-5,"_89":223,"_18":224},{"_36":92,"_13":93,"_60":94,"_62":-5,"_63":64,"_65":32,"_66":67,"_38":95,"_17":69,"_70":96,"_71":97,"_73":52,"_74":-5,"_89":221,"_18":222},{"_36":83,"_13":84,"_60":85,"_62":-5,"_63":64,"_65":32,"_66":67,"_38":86,"_17":69,"_70":87,"_71":88,"_73":52,"_74":-5,"_89":219,"_18":220},[],[84],[],[93],[],[101],[],[109],[],[116],[],[123],[],[19],["D",1787974602620],["D",1789452068287],{"_11":12,"_179":175},{"_11":12,"_172":173,"_174":175,"_138":139,"_176":177,"_178":52},{"_17":103,"_13":16,"_36":64,"_43":44,"_46":37,"_47":168,"_169":54,"_170":44,"_171":57,"_58":14,"_55":12},"ctx",{"_162":-5,"_197":271,"_272":273,"_274":275,"_276":52,"_277":52,"_278":52,"_279":67,"_280":-5,"_281":-7,"_282":-7,"_283":69,"_284":52,"_285":52,"_286":-5,"_287":52,"_288":52,"_289":52,"_290":-5},"ENV",{"_242":243,"_244":245,"_246":42,"_247":248,"_249":250,"_251":252,"_253":254,"_255":256,"_257":258,"_259":260,"_261":262,"_263":264,"_265":266,"_267":268,"_269":270},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","e87eb04e707cf64e7e532c8e8ec395f209e17f15","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
