Observed result

opening script: I'm excited about the Senior AI Engineer opportunity. Based on the scope of the role and my experience, I'd like to discuss a total compensation target of $160,000. Is there flexibility in the package? rebuttals 1 / objection: The budget is frozen. rebuttals 1 / response: I understand. Could we discuss a signing bonus, equity, or a written compensation review after six months? rebuttals 2 / objection: That is above our market rate. rebuttals 2 / response: Could we compare the scope and total package, including bonus, equity, benefits, and growth expectations? rebuttals 3 / objection: I need to check internally. rebuttals 3 / response: Of course. What information would make it easiest to take this request forward? rebuttals 4 / objection: You're already at the top of the range. rebuttals 4 / response: If base cannot move, which parts of the total package can we adjust? batna: Keep interviewing and compare the complete package, growth path, and working conditions rather than base salary alone. counter offer range: $160,000 email followup: Thank you for the offer. I remain very interested and would welcome a conversation about the total compensation package. timing tips 1: Ask after the team confirms fit. timing tips 2: Pause after stating your target. timing tips 3: Get the final package in writing. verdict: Anchor with a specific, evidence-based target and negotiate the whole package. role: Senior AI Engineer target: $160,000 fallback: true note: AI generation was unavailable, so a transparent starter playbook is shown.

Provenance for every timeline entry

  • EXECUTED BY ZAMBOZambo ran the tool call itself.
  • OBSERVED VIA GATEWAYA Zambo gateway observed request and response bytes from the named external executor. Zambo did not run that external action.
  • LOGGED BY AGENTAn agent or local hook reported the action. Zambo attests that the record is unchanged since logging, not that the action happened as described.

Private agent reasoning, built-in client actions, and direct calls to unrelated MCP servers are not included unless an agent or gateway reports them.

What is an execution receipt?

An execution receipt is a public record of a reported AI agent tool call. Its byte commitment and provenance claim can be checked independently; neither alone authenticates the issuer. Read the canonical definition of an AI agent execution receipt.

What the receipt can and cannot prove

What is this?

Zambo's receipt store reports a tool call and records its result. The SHA-256 commitment covers the exact canonical bytes. The provenance label is bound to v0.4 receipt bytes when that check passes, but no pinned signature or trusted issuer key is checked. An anchor can timestamp a fingerprint; it does not authenticate the issuer.
