Share parser modes and collision-free composite keys, enforce architecture guards, and consolidate redundant unit assertions into filesystem, CLI, MCP, and producer-backed workflows. Preserve concurrent upstream boundary fixes and exclude legacy Objective-C class-name bookkeeping labels.
Validation: source/composition suites (3358 passing), focused canonical digest and MCP checks, typecheck/lint, Knip, formatting, architecture guards, and real Foundation archive and Apple legacy simulator CLI/MCP verification. No real Hopper, Ghidra, or IDA verification claim.
