…orchestration - @percy/client createBuild: allow-listed drop-in build sources via PERCY_BUILD_SOURCE, plus dropin-baseline-candidate / dropin-baseline-setup attributes (env or explicit options) the API keys baseline auto-approval on. - @percy/cli-exec: generic baseline-provider discovery (any installed SDK package can declare "@percy/cli".baselineProvider). On an empty project, percy exec uploads the committed baseline screenshots as an auto-approved build #1 before the user's command runs; established projects get a notice pointing at the SDK's explicit setup command. Seeding helpers exported for SDK-contributed commands. - @percy/core: expose the server-decided build source on percy.build so SDKs can key on it through the healthcheck.

Verified E2E against a local percy-api: a web project's snapshot create requires a root resource, so raw-PNG comparison tiles are rejected. Seed uploads now use client.sendSnapshot with the same generated root-DOM + image-resource shape 'percy upload' uses for web projects — Percy renders the baseline in the project's own browsers, so it pairs with the head run's DOM snapshots by (name, browser, width).

Seeding dispatches by project type: web projects seed rendered snapshots (root DOM + image resource); app projects seed raw comparison uploads (tag + tile), exactly how App Percy ingests screenshots. Exec seeding now engages for app tokens too. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

What
CLI-side support for the
@percy/playwrighttoHaveScreenshot drop-in's baseline flow:createBuildaccepts allow-listed drop-in build sources viaPERCY_BUILD_SOURCE(playwright-dropin/playwright-dropin-baseline) plusdropin-baseline-candidate/dropin-baseline-setupattributes (env or explicit options). The API keys baseline auto-approval on these."@percy/cli": { "baselineProvider": "..." }(no framework code enters the CLI, same scaling model as command discovery). On an EMPTY project,percy execuploads the committed baseline screenshots as an auto-approved build ⬆️ Bump @babel/register from 7.10.4 to 7.10.5 #1 before the user's command runs (the suite never executes for the baseline), then starts the head build. Established projects get a notice pointing at the SDK's explicitplaywright:setup-baselinecommand — the API's no-build-persisted sentinel guarantees no stray builds. Seeding dispatches by project type: web → rendered web snapshots (root DOM + image resource, thepercy uploadshape); app → comparison ingest (tag + tile, no render).sourceis kept onpercy.buildso SDKs can key on it through the healthcheck.Depends on
Testing
Client + exec suites green incl. 11 new seeding specs; E2E verified against a local percy-api and on staging (empty web/app seed → head diff flow, established-project sentinel, explicit setup command).
