Vendor Exit Audit Input Contract: Required Fields, Rejection Rules, and Handoff

The direct answer

Define the minimum input record and deterministic rejection rules before an evidence-based map of AI vendor lock-in and exit paths begins. The working output is A versioned input-contract table with required fields, validation rules, owners, and rejected-example fixtures.

For Vendor Exit Audit, the bounded capability is an evidence-based map of AI vendor lock-in and exit paths. Begin only when the team can supply current stack documentation, vendor contracts, interfaces, data flows, and representative workloads. The documented delivery target is a portability report describing what the buyer owns, rents, and can replace; anything broader requires a new scope and a new authority decision.

The copyable input contract

This input contract is for teams that need to know which models, APIs, data formats, tools, and operating procedures they can move. It begins with current stack documentation, vendor contracts, interfaces, data flows, and representative workloads and stays inside the documented workflow: dependency inventory, contract boundary mapping, data and artifact ownership, interface portability, replacement tests, and exit sequencing. For Vendor Exit Audit, the input contract remains reviewable because its decisions have named owners, evidence fields, and stop conditions.

Copy this Vendor Exit Audit table into an intake form or machine-readable schema. Its validation column answers whether an input is usable for an evidence-based map of AI vendor lock-in and exit paths; its rejection column prevents an incomplete record from entering execution as though it were approved.

Example record

{
  "contract_version": "1.0",
  "request_id": "ART-09-01-EXAMPLE",
  "intended_outcome": "Define the minimum input record and deterministic rejection rules before an evidence-based map of AI vendor lock-in and exit paths begins.",
  "input_boundary": "current stack documentation, vendor contracts, interfaces, data flows, and representative workloads",
  "authority": "named owner approval required for consequences outside this artifact",
  "acceptance_status": "NOT_TESTED",
  "reopen_if": "inventorying vendor names but not proprietary behaviors"
}

Contract decision

A record is admitted only when every required field is present, its source is named, and the qualified contract reviewer can run the associated check. It is held when a missing fact could be supplied without changing scope. It is rejected when the requested effect exceeds the authority of the recorded owner or asks this product to promise an outcome outside its boundary.

Run the workflow as a sequence of decisions

The Vendor Exit Audit input contract follows this working sequence: dependency inventory, contract boundary mapping, data and artifact ownership, interface portability, replacement tests, and exit sequencing. Within this artifact, each phrase marks a state boundary for an evidence-based map of AI vendor lock-in and exit paths. A stage output becomes the next named input, while a failed, missing, or unavailable check keeps the dependent input contract decision closed.

Separate failure register

• FAIL-01: Inventorying vendor names but not proprietary behaviors.
• FAIL-02: Assuming an API-shaped interface is semantically portable.
• FAIL-03: Data export tested without import and replay.
• FAIL-04: Exit costs omitted from prioritization.
• FAIL-05: Contracts summarized without qualified legal review.

The register supplies negative cases for the complete acceptance set. A reviewer determines affected checks from observed evidence; array position never asserts that one failure proves or disproves one criterion.

The producer can explain what it attempted, but the qualified contract reviewer evaluates the evidence. If the artifact changes, its prior verdict expires. This is especially important for an evidence-based map of AI vendor lock-in and exit paths, where a plausible narrative can hide a stale configuration, an untested negative case, or an authority mismatch.

Failure and recovery drills

A useful Vendor Exit Audit input contract explains what happens when its happy path breaks. These drills come from the accepted product truth record rather than a claim that every buyer has each failure. Use safe synthetic or authorized observations for an evidence-based map of AI vendor lock-in and exit paths, and keep private credentials out of every fixture.

1. Inventorying vendor names but not proprietary behaviors.

Detect for Vendor Exit Audit: system owner captures a direct readback or safe fixture that makes this input contract condition observable. Its record binds source, time, method, and the current ART-09-01 fingerprint.

Contain the input contract: stop only the affected Vendor Exit Audit path after observing “inventorying vendor names but not proprietary behaviors”. Preserve its failed material and last verified state instead of erasing evidence or blindly repeating an external effect.

Recover and prove: apply the smallest authorized Vendor Exit Audit correction, then have a distinct reviewer re-evaluate the complete accepted check set. Do not select one check merely because it shares this failure's list position. If any affected input contract check cannot run, its result remains NOT_TESTED.

2. Assuming an API-shaped interface is semantically portable.

Detect for Vendor Exit Audit: procurement owner captures a direct readback or safe fixture that makes this input contract condition observable. Its record binds source, time, method, and the current ART-09-01 fingerprint.

Contain the input contract: stop only the affected Vendor Exit Audit path after observing “assuming an API-shaped interface is semantically portable”. Preserve its failed material and last verified state instead of erasing evidence or blindly repeating an external effect.

Recover and prove: apply the smallest authorized Vendor Exit Audit correction, then have a distinct reviewer re-evaluate the complete accepted check set. Do not select one check merely because it shares this failure's list position. If any affected input contract check cannot run, its result remains NOT_TESTED.

3. Data export tested without import and replay.

Detect for Vendor Exit Audit: data owner captures a direct readback or safe fixture that makes this input contract condition observable. Its record binds source, time, method, and the current ART-09-01 fingerprint.

Contain the input contract: stop only the affected Vendor Exit Audit path after observing “data export tested without import and replay”. Preserve its failed material and last verified state instead of erasing evidence or blindly repeating an external effect.

Recover and prove: apply the smallest authorized Vendor Exit Audit correction, then have a distinct reviewer re-evaluate the complete accepted check set. Do not select one check merely because it shares this failure's list position. If any affected input contract check cannot run, its result remains NOT_TESTED.

4. Exit costs omitted from prioritization.

Detect for Vendor Exit Audit: platform engineer captures a direct readback or safe fixture that makes this input contract condition observable. Its record binds source, time, method, and the current ART-09-01 fingerprint.

Contain the input contract: stop only the affected Vendor Exit Audit path after observing “exit costs omitted from prioritization”. Preserve its failed material and last verified state instead of erasing evidence or blindly repeating an external effect.

Recover and prove: apply the smallest authorized Vendor Exit Audit correction, then have a distinct reviewer re-evaluate the complete accepted check set. Do not select one check merely because it shares this failure's list position. If any affected input contract check cannot run, its result remains NOT_TESTED.

5. Contracts summarized without qualified legal review.

Do not select one check merely because it shares this failure's list position. If any affected input contract check cannot run, its result remains NOT_TESTED.

Ownership and handoff

For this Vendor Exit Audit input contract, the adjudication role is qualified contract reviewer. That role judges frozen acceptance evidence for an evidence-based map of AI vendor lock-in and exit paths without becoming the product owner, legal adviser, security authority, or buyer. Its handoff retains open gaps, failed evidence, changed hashes, and the next action permitted for ART-09-01.

Evidence and acceptance

Use these product-specific statements as candidate acceptance checks:

• Dependencies are mapped to interfaces and owned artifacts.
• Exported data is test-imported.
• Representative workloads have replacement fixtures.
• Gaps and switching costs are explicit.
• The exit sequence has rollback points.

For every Vendor Exit Audit input contract check, retain the tested object, environment or source, observation time, method, expected result, actual result, verifier identity, and artifact hash. In this ART-09-01 record, label a direct readback OBSERVED, a reproducible transformation COMPUTED, and an interpretation JUDGMENT; never merge those states into one confident claim.

The product boundary remains controlling: An exit report cannot make an incompatible replacement equivalent or predict every future price, deprecation, legal, or operational change.

Implementation checklist

• The input contract names the distinct reader job: Define the minimum input record and deterministic rejection rules before an evidence-based map of AI vendor lock-in and exit paths begins.
• The input boundary is explicit: current stack documentation, vendor contracts, interfaces, data flows, and representative workloads.
• The intended deliverable is explicit: a portability report describing what the buyer owns, rents, and can replace.
• Every required acceptance check has current evidence or an honest NOT_TESTED status.
• At least one negative fixture covers inventorying vendor names but not proprietary behaviors.
• The qualified contract reviewer is distinct from the artifact producer.
• Rollback or reopen conditions are written before consequential action.
• No ranking, traffic, conversion, compliance, certification, or buyer-outcome guarantee was added.

When this Vendor Exit Audit input contract has a failed item, repair that named item and rerun its dependent checks. Keep the frozen threshold intact; the remaining checks cannot establish that the failed ART-09-01 condition probably holds.
