Give ordinary Evidence creation an explicit unknown-payload input contract
while retaining the strong JSON contract for producer helpers and cooperative
immutable creation. Keep schema admission, input snapshotting and identity
hashing with the Evidence owner.
Remove 32 generic JSON preparses that only fed ordinary Evidence construction.
Preserve semantic format validation, selected-source bindings, standalone
JSON boundaries, typed executions and scenario digest contracts. Invalid JSON
now reports its Evidence parameters/normalized_result/raw_result prefix.
Validation: fresh runtime/catalog build, 560 focused and README tests passed,
4 platform-specific cases skipped, full static/docs checks, test discovery,
duplication and diff checks. New regressions cover omitted semantic optionals,
raw-result defaults and nested undefined refusal without input mutation.
Installed providers, real browsers/Frida/JADX and Linux-only recovery remain
unverified; boundary providers are authored fixtures.
Validate completed reports before cancellation projection, retain valid
Evidence and captured command diagnostics, and convert raw cleanup partials
at their application owner. Record partial Evidence consistently across MCP
handlers. Keep page inspection separate from unfinished bundle analysis.
