Reconstruct dPathLiftActor_c identity and Carpet TU

[andrewboudreau]

Summary

• rebuild daObjRcCarpet_c as one genuine compiler-owned shadow TU
• correct the ROM-proven dPathLiftActor_c identity across symbols, headers, consumers, and TU manifests
• reconstruct dPathLiftActor_c as a 22-function genuine C++ shadow TU with organic destructor pair, initializer, RTTI, vtable, and member-function pointers

Verification

• dPathLiftActor_c: 22/22 text exact; objisolate and relocation destinations clean
• daObjRcCarpet_c: 9/9 exact; daObjPathLift_c: 8/8 exact
• strict standalone PathLift owners and callback: VERIFIED, blind: 0
• ROM-data checks: 0 DIFFERS
• affected consumers, header offsets, references, and port refs pass
• all reconstructed TUs compile: 89/89
• full ROM: 11,085/11,085, 0 mismatches; 106/106 modules exact

Promotion state

dPathLiftActor_c intentionally remains shadow-only: mwcc emits the D1/D0 and six PMF .data sections in a non-retail physical order, so the manifest licenses none of that output.

daObjRcCarpet_c also remains shadow-only. Its nine text functions and each named data record verify individually, but an intact-object probe with #2001 places the resource table before the class RTTI while retail requires RTTI first. The manifest cannot conceal that physical section-order difference; source-order reconstruction continues separately.

Byte-verified means the range carries complete in a delinks.txt, so the ROM build compiled it and compared it to the cartridge. The 218 claimed functions have a src/ file named after the symbol with no NONMATCHING banner, and nothing compiles them -- dsd fills their addresses with the ROM's own bytes. Both together are the 11,216 this project calls matched.
