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.

|

|
|
* - `decorators-legacy` always present: without it decorated sources fail
|
|
* hard instead of reporting recovered syntax, losing every derived fact.
|

* - Unknown paths retain the existing JSX-capable contract (best-effort
|
|
* parse; failures surface via `errorRecovery`, never silent misparse).
