Move each error family out of domain/errors.ts into its own module
(base, core, provider selection/adapter, browser observation,
artifact, evidence, unknown registry, hopper, configuration) and
relocate AnalysisErrorProjection to analysisErrorProjection.
Migrate all 162 importers to the owning modules and delete
errors.ts. No re-export shims; behavior is unchanged.
Move Hopper loader derivation and compatibility projection into the Hopper adapter so BinaryTarget carries only provider-neutral identity and format metadata.
Introduce bounded canonical analysis-profile commitments, exact provider/profile snapshot v2 bindings, legacy snapshot rejection guidance, and backward-compatible profiled Evidence v2 records. Partition cache and replay behavior by target, concrete provider build, and profile while preserving custom Hopper loader overrides.
Propagate profiles consistently through CLI, MCP, composed workflows, and session lifecycle; preserve the 78-tool contract and legacy loaderArgs response projection. Add migration documentation, generated API updates, property regressions, package verification, and real Hopper coverage.
