Resolves PR #1693 review B1 (GITNEXUS_PARSE_CHUNK_CONCURRENCY documented in --help but unimplemented). The chunk loop now pre-fetches chunk file contents up to `parseChunkConcurrency` chunks ahead of the worker-dispatch cursor so disk I/O overlaps with worker compute. Worker dispatch itself stays serial because WorkerPool.dispatch is not reentrant — concurrent calls would race on the shared per-slot busy/in-flight state, regressing the hang/resilience work this PR is built on. The pre-fetch path is the honest interpretation of "concurrent in-flight parse chunks" that the help text advertises: I/O overlap, not parallel worker dispatch. Concurrency value resolution: 1. PipelineOptions.parseChunkConcurrency (threaded from CLI) 2. GITNEXUS_PARSE_CHUNK_CONCURRENCY env var 3. Default 2 (matches the help text) F4 (wildcard-synthesis ordering) is preserved: deferred-state aggregation runs in chunkIdx order because the for-loop iterates sequentially after awaiting each chunk's pre-fetched contents. Cross-chunk processors (processImportsFromExtracted, synthesizeWildcardImportBindings, etc.) still run only after all chunks complete — they see deterministic input regardless of file-read completion order. Concurrency=1 produces behavior identical to the pure-serial loop; that's the regression baseline. New test: parse-impl-chunk-concurrency.test.ts - Asserts graph output is identical (nodeCount + relationshipCount) between parseChunkConcurrency=1 and =2 — the critical correctness invariant. Exact .toBe(N) comparisons per DoD §2.7 (the second run's counts must equal the first run's exactly). - Pins specific fixture symbols (foo/bar/Baz) under both parseChunkConcurrency=1 and the env-fallback (3) path. - Env-fallback test confirms GITNEXUS_PARSE_CHUNK_CONCURRENCY is honored when the option is undefined. |
