Raw continuity tokens must never be written to Brain blobs/files, scheduled prompts, checkpoints, or successor handoffs.\n- Every accepted heartbeat atomically consumes the presented token and returns exactly one fresh token.\n- Wrong, replayed, late, expired, terminal, ambiguous, or CAS-losing uses fail closed. There is no blind retry that can recreate continuity.\n\nThe protocol adapts OAuth refresh-token rotation / replay-detection semantics (RFC 9700 §4.14.2) to continuity measurement. Passing Stage A does not establish physical identity, independence, P_real, Work product identity, or superhero capacity.\n\n## HTTP surface\n\n`GET /health` returns the frozen policy and non-production classification.\n\n`POST /start` with `{ \"agent_id\": \"...\" }` creates one canary and returns the raw start token once.\n\n`POST /heartbeat` with `{ \"canary_id\": \"...\", \"agent_id\": \"...\", \"token\": \"...\" }` atomically consumes that token and returns the rotated token once.\n\n`POST /finish` with the same binding terminalizes the run. PASS is possible only after the 100-minute target; early finish is FAIL.\n\n`GET /receipt?canary_id=...&agent_id=...` returns hash/timestamp/sequence evidence only.\n\n## Qualification\n\nRun `stage_a_adversarial_test.ts`. It covers concurrent same-token race, stale-token replay, wrong canary/agent, late heartbeat, absolute expiry, module/runtime reload persistence, hash-only durable evidence, terminal replay, malformed input, deterministic receipt reconstruction, and policy freeze.\n\nThis Val is intentionally isolated from the canonical Brain kernel/admission/protocol. It performs zero paid spend and no Sprites calls.\n",[],[242],["D",1789327762933],[],[18,76],["D",1789327762933],[],[18,88],["D",1789327762933],[],[18,93],["D",1789327762933],[202,203,204],[18],["D",1789327762933],["D",1789501878689],{"_11":12,"_148":82},{"_11":12,"_143":144,"_81":82,"_31":80,"_145":146,"_147":30},{"_39":134,"_13":16,"_33":36,"_135":97,"_136":-5,"_137":-5,"_138":-5,"_139":-5,"_140":-5,"_141":14,"_142":12},"ctx",{"_54":-5,"_167":299,"_300":301,"_302":303,"_304":30,"_305":30,"_306":30,"_307":24,"_308":-5,"_309":-7,"_310":-7,"_311":26,"_312":30,"_313":30,"_314":-5,"_315":30,"_316":30,"_317":30,"_318":-5},"ENV",{"_270":271,"_272":273,"_274":16,"_275":276,"_277":278,"_279":280,"_281":282,"_283":284,"_285":286,"_287":288,"_289":290,"_291":292,"_293":294,"_295":296,"_297":298},"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"]
