A Go-or-No-Go Pilot Plan for an Evidence-based Map of AI Vendor Lock-in and Exit Paths

The direct answer

Use a bounded slice to test whether “dependencies are mapped to interfaces and owned artifacts” holds, make “inventorying vendor names but not proprietary behaviors” a stop case, and leave expansion to the qualified contract reviewer.

For an evidence-based map of AI vendor lock-in and exit paths, the relevant audience is teams that need to know which models, APIs, data formats, tools, and operating procedures they can move. The decision should cover dependency inventory, contract boundary mapping, data and artifact ownership, interface portability, replacement tests, and exit sequencing. The supplied boundary starts with current stack documentation, vendor contracts, interfaces, data flows, and representative workloads and ends with a portability report describing what the buyer owns, rents, and can replace, presented in reviewable form.

An exit report cannot make an incompatible replacement equivalent or predict every future price, deprecation, legal, or operational change.

Write a pilot charter that can return no

Choose the riskiest assumptions

Start with the assumptions behind “dependencies are mapped to interfaces and owned artifacts” and “exported data is test-imported”.

Include “inventorying vendor names but not proprietary behaviors” and “assuming an API-shaped interface is semantically portable” as bounded negative fixtures.

Freeze a comparison baseline

The comparison asks whether “representative workloads have replacement fixtures” holds without weakening the authority or evidence rules.

Run the canary as a sequence of gates

1. Confirm that the system owner still authorizes the charter.
2. Verify the supplied boundary matches current stack documentation, vendor contracts, interfaces, data flows, and representative workloads.
3. Exercise the normal path and inspect whether “dependencies are mapped to interfaces and owned artifacts” holds.
4. Run the failure case “data export tested without import and replay” without widening authority.
5. Compare the candidate and baseline evidence for “gaps and switching costs are explicit”.
6. Ask the qualified contract reviewer to record go, revise, or stop.

Use explicit decision outcomes

Prove rollback before expansion

If the failure case “inventorying vendor names but not proprietary behaviors” occurs, stop writes, capture the live state, and compare it with the manifest before rollback.

Close the pilot with a bounded claim

A pilot is only a demonstration when it cannot stop for “inventorying vendor names but not proprietary behaviors” or withhold expansion after the criterion “dependencies are mapped to interfaces and owned artifacts” fails.

A passing result supports only the tested slice of an evidence-based map of AI vendor lock-in and exit paths.

How the sources bound the pilot plan decision

For an evidence-based map of AI vendor lock-in and exit paths, the live catalog limits the offer to two elements. The supplied boundary is current stack documentation, vendor contracts, interfaces, data flows, and representative workloads. The catalog names the deliverable as a portability report describing what the buyer owns, rents, and can replace. It cannot establish whether “dependencies are mapped to interfaces and owned artifacts” holds in the buyer's environment.

Connect those narrow roles to a local fixture for “assuming an API-shaped interface is semantically portable” rather than treating citation status as a pass.

For an evidence-based map of AI vendor lock-in and exit paths, limit the conclusion to the documented workflow and let the procurement owner retain the current source-to-claim map. New authority or data requires the system owner to review the evidence boundary again.

Product-specific pilot plan review drills

These drills connect an evidence-based map of AI vendor lock-in and exit paths to concrete inputs, failures, acceptance statements, and owners. For an evidence-based map of AI vendor lock-in and exit paths, the drills bound the canary, stop rule, and expansion decision.

The pilot boundary for an evidence-based map of AI vendor lock-in and exit paths records current stack documentation, vendor contracts, interfaces, data flows, and representative workloads but exercises only synthetic, non-secret markers. The system owner confirms that no enqueue, send, write, or external call may exit the canary fixture throughout or after the pilot.

Charter boundary

Exercise the charter boundary review against the known risk “inventorying vendor names but not proprietary behaviors”. Ask the system owner to mark the earliest point where the expected handoff diverges.

The proof package identifies the input boundary as current stack documentation, vendor contracts, interfaces, data flows, and representative workloads and includes a direct check that “representative workloads have replacement fixtures” holds. Assumptions stay separate from observed artifacts.

The qualified contract reviewer records a pass to permit the next bounded check on a portability report describing what the buyer owns, rents, and can replace, or a hold naming the missing proof for “representative workloads have replacement fixtures”. The charter boundary review advances with pass for support, fail for contradiction, and hold for unresolved evidence.

A new owner, fixture, or consequence for “inventorying vendor names but not proprietary behaviors” sends the charter boundary review back to the system owner for review.

Risk hypothesis

Let the procurement owner open the risk hypothesis review with this case: “assuming an API-shaped interface is semantically portable”. They isolate the affected decision from the rest of dependency inventory, contract boundary mapping, data and artifact ownership, interface portability, replacement tests, and exit sequencing.

Use an authorized test case within the boundary covering current stack documentation, vendor contracts, interfaces, data flows, and representative workloads to establish whether “the exit sequence has rollback points” holds. Record configuration and reviewer identity beside the result.

The qualified contract reviewer advances only when the receipt establishes “the exit sequence has rollback points”. Missing proof keeps a portability report describing what the buyer owns, rents, and can replace on hold; contradictory proof makes the qualified contract reviewer record fail. The risk hypothesis review advances with pass for support, fail for contradiction, and hold for unresolved evidence.

Retest this decision when the team changes dependency inventory, contract boundary mapping, data and artifact ownership, interface portability, replacement tests, and exit sequencing or can no longer reproduce the record for “the exit sequence has rollback points”.

Baseline comparison

Place a safe fixture showing “data export tested without import and replay” at the boundary tested by the baseline comparison review. The data owner records the permitted path and the first denied transition.

Bind the fixture to a scope record covering current stack documentation, vendor contracts, interfaces, data flows, and representative workloads; its expected condition is that “exported data is test-imported” holds. The fixture version is part of the receipt.

The qualified contract reviewer closes the baseline comparison review only when the record resolves “exported data is test-imported”; otherwise the listed deliverable remains provisional. The baseline comparison review advances with pass for support, fail for contradiction, and hold for unresolved evidence.

Recheck the baseline comparison review if the rollback path changes or the qualified contract reviewer cannot reconstruct how the criterion “exported data is test-imported” was judged.

Canary case

Reproduce a safe case involving “exit costs omitted from prioritization” as the entry condition for the canary case review. The platform engineer preserves the last state that the workflow can prove.

Pair a scope record covering current stack documentation, vendor contracts, interfaces, data flows, and representative workloads with a direct observation of whether “gaps and switching costs are explicit” holds. The system owner retains the source and result together.

The qualified contract reviewer judges the canary case review against “gaps and switching costs are explicit”. The next step is authorized only for the part of a portability report describing what the buyer owns, rents, and can replace covered by that evidence. The canary case review advances with pass for support, fail for contradiction, and hold for unresolved evidence.

Return the record to hold when the fixture, dependency, or permission used to judge whether “gaps and switching costs are explicit” holds changes materially.

Stop decision

For the stop decision review, freeze a case involving “contracts summarized without qualified legal review”. The system owner identifies the affected handoff before any repair begins.

Select a representative authorized case within the boundary covering current stack documentation, vendor contracts, interfaces, data flows, and representative workloads for the stop decision review. Its expected result is that “dependencies are mapped to interfaces and owned artifacts” holds.

The qualified contract reviewer limits acceptance to “dependencies are mapped to interfaces and owned artifacts” and nothing beyond it, leaving a named hold for any unsupported part of a portability report describing what the buyer owns, rents, and can replace. The stop decision review advances with pass for support, fail for contradiction, and hold for unresolved evidence.

Reopen this result after a change to the input, the authority of the system owner, or the workflow condition represented by “contracts summarized without qualified legal review”.

Expansion record

The expansion record review starts with the failure case “inventorying vendor names but not proprietary behaviors”. Its first owner is the system owner, who captures the current workflow state without changing it.

Use a scope record covering current stack documentation, vendor contracts, interfaces, data flows, and representative workloads as the controlled source for a test of “representative workloads have replacement fixtures”. The procurement owner flags evidence from a different state as non-comparable.

If the case establishes “representative workloads have replacement fixtures”, the qualified contract reviewer authorizes the next limited action. Unresolved evidence keeps a portability report describing what the buyer owns, rents, and can replace on hold; contradictory evidence makes the qualified contract reviewer record fail. The expansion record review advances with pass for support, fail for contradiction, and hold for unresolved evidence.

The judgment expires after a material change to dependency inventory, contract boundary mapping, data and artifact ownership, interface portability, replacement tests, and exit sequencing or to the evidence used by the qualified contract reviewer.

Frequently asked question

How should I pilot Vendor Exit Audit?

Pilot a narrow slice using current stack documentation, vendor contracts, interfaces, data flows, and representative workloads. Require evidence that dependencies are mapped to interfaces and owned artifacts, and stop on the failure case “inventorying vendor names but not proprietary behaviors”. The qualified contract reviewer records go, revise, hold, or rollback.

A product bridge, with a boundary

The Vendor Exit Audit is the relevant sincLLM offer for this narrow problem. The frozen live catalog describes its required boundary as current stack documentation, vendor contracts, interfaces, data flows, and representative workloads and its deliverable as a portability report describing what the buyer owns, rents, and can replace. The buyer must judge fit and results in its own environment; the catalog does not certify compliance, safety, or technical sufficiency.
