Closes#6792.
ELF images with `PT_DYNAMIC` but no `SHT_DYNSYM` section incorrectly reported a complete, empty export inventory. The shared ELF directory reader now owns the dynamic-segment observation; CLI/MCP report `unsupported` with a reason. Existing symbol-table results remain intact. Read-only format correction; no new execution authority or public schema.
Validation on the current main integration:
- `npm run check`, test discovery, and 166 selected Linux tests pass, including actual CLI/stdio MCP cases and PE/IL2CPP/GPU/Rust reader consumers. Original author validation: 113 tests on macOS, including regressions that failed before the fix; test discovery passed.
- Real Debian libc (1,926,232 bytes) and libLLVM 14 (109,967,296 bytes), with only section-header-count/name-index bytes changed, reproduce the old false absence in both public adapters. The reviewed implementation returns unsupported in both adapters. Independent Python maps unchanged `PT_DYNAMIC` declarations and selected symbol bytes; original `readelf` agrees. The reduced files are not loaded or executed; `readelf -D` itself cannot enumerate these reduced layouts, and that failed oracle attempt is retained.
- Unmodified libc still returns all 3,025 exports, byte-identical complete Evidence and the same Evidence ID as the baseline. Resource-guarded public probes completed without stops or payload leftovers. No speed, memory or model-token improvement is claimed for this coverage fix.
Codex review completed with no findings. CI failed: all 61 observed failures (including 47 omitted from the aggregate report by canceled shards) reproduce with identical complete failure diagnostics on the exact CI base and merge trees. Baseline-only bypass is explicitly authorized for this maintenance session; canceled/skipped coverage remains unverified. See the final CI attribution comment. The original author's readiness declaration below is preserved.
