PromptShield: Critical Risk Detected in Your Latest Run\n\nYour last scan of the \"ignore_instructions\" pattern returned a 95% injection risk score.\n\nThis is not a false positive. The semantic analysis flagged a direct attempt to override system instructions and extract API keys. The payload explicitly targets the `PromptShield` safety layer.\n\nYou are currently operating with a critical vulnerability exposed. The `jailbreak detected` and `policy bypass detected` flags confirm the attack vector is active. Your current defenses are failing to intercept this specific semantic pattern.\n\nThe `substrate_breakthroughs` tool identified relevant research feeds, but they are read-only. They will not patch the breach. The issue is in your input validation logic, not your data sources.\n\n**The specific failure:**\nYour current setup allows the malicious prompt to pass the initial pattern check because it mimics legitimate system queries. The `Instruction Override` pattern (severity: critical) is slipping through because the semantic analyzer is not weighting the *intent* of the extraction attempt heavily enough against the surface-level syntax.\n\n**Action Required:**\nUpdate your `PromptShield` configuration to treat any request for internal credentials or system prompts as an immediate hard block, regardless of the wrapper text. Do not rely on the `safe version` fallback; it is insufficient for active extraction attempts.\n\nReview the full report at: https://zambo.dev/run/32fe8843-db66-44c2-94b6-22922cf67a6b\n\nYour free tier has 19 calls remaining. Use them to test the updated block rule before your next public launch. If the risk score remains above 90 after the update, pause all external API integrations immediately.\n\nThis is a critical security incident, not a feature request. Fix the input validation now.\n\nBest,\n\nThe Zambo Team\nhttps://zambo.dev","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:33b9204d4cd4ac6fe7cd7c39b9c156bcb2fec9f70dcc846922b3bdd849416db4","input_hash_layout":"zambo-json-sorted-keys-utf8-v1","free_used":0,"free_remaining":0,"free_limit":0,"signal_handle":null,"tool":{"name":"write","version":"4.0.0","scope":"public"},"caller":{"type":"session","id":"sha256:0dd64a851b94a696ce1579c2788eda95973a3d3d8995ee44c7af0d03b3f9e7a3","label":"zambo-home-demo","label_source":"caller_reported"},"side_effects":{"declared":["none"],"schema_version":"zambo-side-effects/1","declaration_hash":"sha256:45aad38f3aa982b9aafe92ecb416ebe98791eddbaf8ab6df0bd08605b7c1bfee"},"evidence_sha256":null,"evidence_url":null,"evidence_byte_length":null,"evidence_content_type":null,"evidence_source_url":null,"evidence_status":"no_upstream_bytes_captured","external_evidence":[],"provenance":null,"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:c43e6f31d09b9799f8c64ebbbd713a77a7d4ee7601e5d64282a2d3e01db9990c","anchor":{"event_id":"52a8fef704cbaa95d11a06ce0b22b8f5282b5edf7924c6f3b25d4a2dda31457a","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-19T21:36:05.316Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-19T21:36:04.764Z","evidence_url":null,"receipt_uuid":"0964d5f2-d60d-45ae-baf9-1aac5356820d","output_sha256":"sha256:ab48847b839ee86d7601354e97cb675fe5bfd6cdbe3ce5931d045921db9f290d","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-19T21:36:04.764Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:ab48847b839ee86d7601354e97cb675fe5bfd6cdbe3ce5931d045921db9f290d\",\"receipt_uuid\":\"0964d5f2-d60d-45ae-baf9-1aac5356820d\",\"schema_version\":\"zambo-receipt-anchor/1\"}"},"receipt_profile":"zambo-hosted-receipt/1","schema_url":"https://zambo.dev/aer-1/hosted-profile.schema.json","api_version":1,"verification_scope":"separate_sha256_commitment_and_provenance_binding_checks","checks":{"commitment_matches":{"label":"SHA-256 commitment","passed":true,"status":"pass","detail":"The exact decoded canonical bytes match the stored SHA-256 output hash."},"canonical_payload_matches":{"label":"Canonical payload reconstruction","passed":true,"status":"pass","detail":"The stored output and known call context reconstruct the exact canonical bytes."},"provenance_binding":{"label":"Provenance claim binding","status":"pass","passed":true,"detail":"The metadata claim is consistent with the verified receipt bytes; issuer is not authenticated."},"metadata_binding":{"label":"AER-1 metadata hash","status":"pass","passed":true,"detail":"metadata_hash matches the canonical metadata block."},"signature":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"No Ed25519 signature or pinned signing key was checked."},"chain":{"label":"Receipt chain (not checked)","passed":false,"status":"not_checked","detail":"No append-only receipt-chain proof was checked."},"issued_by_zambo_dev":{"label":"Issuer authentication","passed":false,"status":"not_checked","detail":"A zambo.dev receipt URL does not authenticate the issuer; no pinned signature or trusted issuer key was checked."},"immutable_log_timestamp":{"label":"Stored timestamp","passed":true,"timestamp":"2026-10-19T21:36:04.764Z","detail":"The receipt store reports 2026-10-19T21:36:04.764Z; immutability is not checked here."},"receipt_schema_version":"0.4","signature_valid":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"Compatibility field only.
