No traversal segments.\\n\\n## Worker health\\n\\nThe Val endpoint can be alive while the persistent worker is dead.\\n\\nTreat:\\n- HTTP 200 = transport worker heartbeat currently healthy;\\n- HTTP 503 = degraded/down/inconsistent transport. Inspect the response and traces.\\n\\nWhen health is 503, queued jobs may remain READY. Do not invent their results.\\n\\n## Direct Sprites emergency boundary\\n\\nDirect Sprites is not an automatic fallback.\\n\\nUse a non-Sprites route or extend the bridge first. Direct Sprites is reserved for an explicitly authorized maintenance emergency after acknowledging it can trigger the platform materialization approval.\\n\\n## After every task\\n\\n1. preserve consequential evidence and hashes;\\n2. reconcile current workstream generation;\\n3. commit through the Brain;\\n4. verify chain/claim graph when consequential;\\n5. claim the next eligible task;\\n6. continue unless mission complete or a genuine external boundary remains.\\n\\n## Goal\\n\\nA new chat must be able to join the same canonical Brain without recurring Sprites connector approvals, while failures remain visible instead of being laundered into fake liveness.\\n\",\"regression\":\"import { sqlite } from \\\"https://esm.town/v/std/sqlite/main.ts\\\";\\nimport {\\n
