Part of #7524 (census #7709). Checklist: partial [c:bb8e1760] -- PARSE ODO tables and floats, CONVERTING (#7949), elementary source/receiver

Class

JSON PARSE receiver tables: a JSON array into a fixed OCCURS item (elementary or group elements, nested fixed tables), translated from IBM's table format. Same mechanism as the GENERATE table slice; json_tree now allows tables for PARSE and keeps ODO and floats GENERATE-only.

Sibling gaps

• PARSE into OCCURS DEPENDING ON table: refused by name. No burned program uses JSON.
• PARSE float items, elementary receiver, CONVERTING (det: JSON GENERATE CONVERTING ... TO JSON BOOLEAN (Part of #7524, #7709) #7949), JSON-STATUS after an exception: unchanged holes.
• Correction to X77: SUPPRESS WHEN / EVERY is a JSON GENERATE phrase in IBM's syntax, not a PARSE gap.

Facts checked

• Array length differing from the OCCURS count: IBM pages state nothing, so a runtime Hole, not a guess.
• Non-array for a table: JSON-CODE 104 (type mismatch, as for scalars). Top-level array stays a Hole.
• Register X77 updated; oracle-unbacked, no L2+ claim. No burned program uses JSON, so no case or golden moves.
• Tests: test_det_json_parse/generate (74 pass, runtime run on JDK 17), audit_check clear, cobolrt API check holds.

Cross-repo

None. Overlaps open #7949 in gen.py and cobolrt_api.json; whichever merges second rebases.

Lessons for agents

cobolrt_api.py --promote-used only reports; a new public runtime method used by emitted code needs "visibility": "public" and the summary counts edited by hand in cobolrt_api.json.
