Attempt independent resource cleanup without losing primary failures, retain unresolved owners, and publish completion after release. Bound existing producer commands, preserve helper return values, and settle startup and fixture children on failure.
Validation: 29 focused boundary tests passed; actual helper-value and import-bound filesystem cleanup controls passed. The real inert-child termination control and targeted JavaScript binding checks passed, alongside typecheck, lint and formatting. Live Ghidra, Cutter, Electron GUI and Windows addon qualification was not run.
Extend the existing real Electron public-tool fixture with assignment aliases for BrowserWindow, contextBridge, ipcMain, and ipcRenderer. Assert exact static recovery counts and observe the handler invocation after a real click.
Verified the public CLI/stdio MCP fixture, IPC invocation, cancellation, and owned-process cleanup against checksum-verified Electron 43.3.0 on macOS ARM64. Build and check:fast pass. The separate readiness reload/crash scenario still fails on a destroyed execution context; this commit does not claim the full verify:electron lane passes.
* fix(mcp): deliver tool errors within advertised schema contracts
Retain complete typed JSON error content while omitting non-conforming
structured errors at the public transport boundary. Recover oversized
diagnostics into Evidence before removing their private structured carrier.
Update schema-validated client readers and cover actual stdio delivery.

* test(mcp): read typed errors in canonical Evidence regressions
* test(mcp): validate public error diagnostics in acceptance workflows
Deliver complete Evidence directly through MCP with required nullable analysis profiles and immutable per-server delivery settings. Bind selected environments at construction and require typed cleanup outcomes with retained retry ownership.
Remove test-only routing, duplicate session and snapshot metadata, producer-field repairs, and ambiguous provider arguments. Separate artifact byte identity from occurrence classification and retain typed source-map and partial native facts across CLI, MCP, and verifier consumers.
BREAKING CHANGE: obsolete Evidence envelopes, session aliases, incomplete snapshots, and missing normalized producer facts are no longer accepted.
