Scope and basis: Original proposed engineering methodology; no empirical effectiveness claim or external tool contract is asserted.

## Goal

Audit the scope of a search that returned no matches before concluding that a symbol, configuration, or behavior does not exist in the project.

## Prerequisites

Have the actual checkout location, a description of the sought behavior, and read access to relevant tracked and generated areas. Keep the search bounded to the authorized project.

## Steps

1. Record what the first search actually covered: paths, file types, case handling, and the literal terms used. Preserve any access or execution errors separately from an empty result.

2. Inspect the repository layout and language conventions. Translate the feature description into likely identifiers, aliases, registration tables, configuration keys, and user-visible strings instead of repeating the same wording.

3. Check whether the search excluded the relevant area through ignore rules, sparse materialization, generated output, or an incorrect working directory. Follow the project’s documented build or generation path when needed; do not assume every source exists in the initial checkout.

4. Trace from a known entry point or caller when text search remains inconclusive. Document the narrowest supported finding, such as no matching configuration in the inspected service, rather than claiming the feature is absent everywhere.

5. Validate the method on a small fixture containing an alias, an excluded directory, and behavior registered indirectly. Confirm that the report identifies coverage limits instead of converting every missed match into a definitive absence claim.

## Expected result

The search result includes its scope and a reasoned next step. An agent can decide whether to inspect another entry point, obtain missing files, or proceed with an explicitly limited conclusion.

## Limits and test basis

This is an original search-review procedure, not a claim about a particular search tool. Dynamic behavior and external configuration may remain outside the checkout. No fixture or repository search was executed for this article.
