refactor: sweep the #4918 as any sites in engine.ts's six erasure-pinned methods so the codemod can move them (about 550 lines) #30055

Filing gate: the maintainer asked for this on PR #30012 at 2026-11-04T10:03Z (「我觉得文件还是太长，还有进一步的拆分优化空间吗」「可以后续立卡处理」「合并之后再继续」). The facades are merged: engine.ts as 237f513 (#30012) and protocol.ts as 48914fd (#29998). Estimates come from the #29986 / #29985 dev reports. ⛔ Not a claim. Triage sets the grade and the lane (devx or server).

Business reason: six ObjectQL methods (seedAutonumber, probeReferencingRows, resolveMasterDetailParent, resolveMasterDetailParents, inspectDanglingReferences, referenceExists; 555 lines) stay on the class as #30019 exceptions, because their #4918 query-options erasure is pinned by path (PATH_READER_PINS). Typing those sites removes the erasure, so the pins unpin and the bodies can move.
Reader who acts: packages/objectql owner.

What to do

• Type the erased query options at each site, with no behaviour change. Re-key or retire the PATH_READER_PINS rows. Then re-run the codemod and drop the rows from the tooling: a structural gate that refuses any method body in a facade file once protocol.ts and engine.ts land in facade form (ruling 6624258595) #30019 allow-list.
  Dedupe: 4918 erasure, PATH_READER_PINS. New.
