📄 Description

Behavior

Import explicitly selected gamecube-dol images through existing POSIX Ghidra, with header-owned text/data/BSS ranges and attestation of imported bytes, permissions and address spaces. Cached MEM1 only; Wii MEM2, uncached aliases, REL/RPX, r2/r13 recovery and target execution are outside scope. Hopper/IDA/Windows decline this format. Refs #1741; this does not complete the broader console-analysis request.

Native procedure search/list contracts share the domain row schema and preserve symbol provenance through complete, summary and retained-page delivery. The import fixes preserve real inventory symbol provenance, request complete verifier delivery, reuse cleanup owners, derive BSS once, apply a counted/bounded private v2 plan and preserve qualified foreign-space observations. Main's newer package/process ownership is retained; its Windows verifier gains only the DOL collision fixture.

Verification

Real Linux Ghidra 12.1.4/JDK 21 public CLI/MCP stock-PowerPC passes before/after the feature refactor and again on the final combined source. Independent readelf/header, mapping/BSS, entry/callee, decompilation/bytes and final empty lineage pass. Gekko is unavailable and skipped; no new real Windows/Hopper/IDA or commercial-console claim.
Final combined snapshot: 1,062 passing checks / 4 platform skips across IPS, Android, IL2CPP, DOL and main's changed process/package owners. Cached build passes. check:fast reproduces only main's release-test includeFiles type error; this is a recorded failure. Standalone lint, full formatting and documentation pass. Earlier pinned feature-source check:fast and all 326 DOL checks pass (3 Windows skips).
Six actual SDK query tasks preserve requested facts/input digests. Whole-task token estimates, elapsed/CPU/family-memory costs, cache scope and unverified coverage are in the report. No general performance gain is claimed. Earlier contributor macOS/commercial-image evidence was not rerun here.

The final public-search correction passes 42 targeted checks and a real SDK matching-search task. The old schema fails with the captured symbol-bearing row. The real task records an initial Java-readiness cleanup failure and a successful fresh-session retry; both attempts, catalogs and calls are included in the report. Earlier 1,062-check combined validation keeps its stated source pin.
