Bite-sized plan for spec 0069. Six tasks: complete schema fields across the
13 examples + 4 references (own default, existing borrow preserved); rewrite
param_modes_all + spec.md section 4 (own Int / borrow boxed-ADT, value/boxed
rule); add loop_sum + new_rawbuf examples; spec_completeness variant coverage
+ Intrinsic allowlist; regenerate rendered + green render suite; migrate
mock_full_run fixture + green harness suite.
All verbatim .ail/.ail.json bodies parse-gate verified this session. The gate
caught a real language drift the spec had to absorb: borrow over an unboxed
value type (Int) is now a borrow-over-value error, so param_modes_all borrows
over a boxed ADT instead.
