Two measured changes on the TypeScript corpus (81,397 files; v0.9.0 17.9 s, before 44.1 s, after 37.5 s): - cov_rebuild_shadow_graph upserted every directory segment for every failure row — 13,243 parse-partial baseline files under one tests/ subtree meant ~80k redundant node/edge round-trips, 9.1 s of a 9.2 s coverage_replace. An in-rebuild path->id map creates each directory once; identical graph (edges deduped by unique key before, absent now). Coverage block 9,162 -> 2,920 ms. Sub-block timings (publish.timing.coverage: del/rows/prune/meta/commit + row_count + detail_bytes) are kept — the caller-level number could not name the culprit. - JS/TS export_statement is an import CONTEXT only in its re-export forms (source field, or a bare specifier list without a declaration). The old is_export_of_declaration blacklist missed TS-only forms (ambient_declaration, function_signature, module_declaration), running declare-heavy subtrees (.d.ts, export namespace) behind inside_import: suppressed usages + per-identifier ancestor walks. Positive detection replaces the blacklist; +3,954 restored usage edges on the corpus, nodes identical. (Measured perf-neutral here — kept for correctness.) Suites green incl. store_nodes/edges/search, mcp, extraction, ts_lsp, complexity, and the 53-language calls-breadth contract. Refs #1669. Signed-off-by: Martin Vogel <martin.vogel.tech@gmail.com>
