Index a fixture for every grammar through the full pipeline and assert graph-level invariants: golden node-label histograms, def/node breadth, CALLS and IMPORTS breadth, presence of all 26 pipeline edge types (structural, type-relationship, service/dataflow, and similarity), no-crash, and call resolution. Reproduced quality gaps (under-extraction, import-extraction, and CALLS-resolution) are kept as hard failures for the fix phase rather than skipped. Adds a real-repo scale tier (scale_contract.sh) and ignores local-only private/ scratch.
