Accumulate observations once per structural path instead of allocating and serializing a path for every payload value. Remove the CDP body-shape wrapper and retain primitive, empty-array, and literal-property semantics.
Validation: CDP capture/comparison regressions and CLI/MCP boundary checks pass; 1,507 differential cases match the previous implementation. A 2.5 MB repeated-row workload improves from 105.0 ms to 14.6 ms warm median across alternating runs. Real browser providers were not exercised.
Move the indexed sections walk shared by the browser fetcher and
the artifact reader into domain/sourceMapEnvelope with the
fetchers stricter offset validation as an option; both validators
keep their leaf strictness. Rename the browser CDP stringValue to
cdpStringValue across its 18 files, fold the fingerprint duplicate
into the static helper, and rename the version-keys shadow to
nonEmptyString.
