Greptile Summary

This PR adds test mode support for a Portal Prebid Test Site (publisher simulation), introducing three enhancements to the Start.io bid adapter.

• imp.tagid from params.placementId: Maps the optional placementId bid param to the ORTB imp.tagid field, coercing it to a string.
• ext.prebid.channel population: Always sets { name: 'pbjs', version: '$prebid.version$' } on every outgoing request so the endpoint can identify the Prebid.js client version.
• Test mode via params.testAdsEnabled: When truthy, sets request.test = 1 in the ORTB body and appends &testAdsEnabled=true to the endpoint URL; corresponding tests cover both the enabled and disabled cases.

Confidence Score: 5/5

Safe to merge — all changes are additive and guarded by optional chaining; no existing paths are modified.

The changes are purely additive: a new imp field, a new ext field, and a conditional test-mode flag. Each new feature is covered by a dedicated test. No existing request-building or response-parsing logic is altered.

No files require special attention.

Important Files Changed

Filename	Overview
modules/startioBidAdapter.js	Adds imp.tagid from params.placementId, sets ext.prebid.channel, and introduces test mode via params.testAdsEnabled (sets request.test=1 and appends a URL query param)
test/spec/modules/startioBidAdapter_spec.js	Adds four test cases covering channel advertisement, placementId→tagid mapping, request.test flag, and testAdsEnabled URL parameter
