PromptShield flagged an instruction override attempt with 95% confidence, identifying a jailbreak vector aimed at leaking system instructions. The scan completed in 736ms, and the receipt confirms the saved bytes remained unchanged. That is the core value: verifiable safety.\n\nZambo is now launching with two primary capabilities. First, PromptShield acts as a deep-scanning layer, detecting injection risks, policy bypasses, and malicious intents before they execute. It provides a clear risk level, from low to critical, and logs every detection with a receipt. Second, the capability search engine connects you to executable tools. For example, a query for \"AI research\" surfaced `substrate_breakthroughs`, a read-only tool offering live AI research feeds without side effects. It also identified `VeriAI` for cryptographic trust scoring, noting that this specific tool requires a human web action rather than a direct MCP route.\n\nThese are not finished products in a box. They are live, executable capabilities. The system distinguishes between safe, callable tools and those requiring external action. It flags potential customers as prospects, not users, and treats every receipt as proof of unchanged data, not proof of correctness.\n\nI want to invite you to test this directly.\n\n**Action:** Run a single prompt that you previously thought was safe. Let PromptShield scan it. Check the receipt. See if the risk score aligns with your intuition.\n\nNo sales pitch. No demo. Just the raw output of the detection engine.\n\nIf the results surprise you, reply with \"details.\" If not, archive this email.\n\nBest,\n\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:919fe0560099d54d4c0c896f42ed74729deb190de14558274f45201ee231db7d","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:b4b791d532f9505086348fc0bfa1d9376e464c50b3f8a0472e808280f75fe6ed","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:fb81045e599da6fa73a26d364b847a36537b009d5c1783928b5a931b2e6d15a7","anchor":{"event_id":"e92ddbfea873412a3e058721f4d4a3797f36b10c4a0e83b3a700c57696db7f3e","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-16T08:54:30.349Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-16T08:54:29.791Z","evidence_url":null,"receipt_uuid":"3cc9e4c4-53c7-48bf-b4f2-1e01d8adc937","output_sha256":"sha256:9d588a3527981e8900d57eed508c080774ce7659864ec6f07dec8dbb70869157","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-16T08:54:29.791Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:9d588a3527981e8900d57eed508c080774ce7659864ec6f07dec8dbb70869157\",\"receipt_uuid\":\"3cc9e4c4-53c7-48bf-b4f2-1e01d8adc937\",\"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":"2026-10-16T08:54:29.791Z","detail":"The receipt store reports 2026-10-16T08:54:29.791Z; 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.
