Adds `anchor_in_jsonc_block(md, anchor) -> bool` to
`design_schema_drift.rs` — a line-walking helper that toggles on
``` / ~~~ fence markers (any info-string: jsonc, json, or
unspecified — all count) and returns true only if the anchor
appears inside fenced content. Re-routes the seven
`DATA_MODEL.contains(anchor)` assertion sites in the file
(Term, Pattern, Type, Literal, Def, ParamMode, nested struct
keys) onto it.
The carrier from `debug` named six sites; in the implement phase
the orchestrator flagged a seventh — `design_md_anchors_nested_
struct_keys` — that exhibited the identical scope-widening bug and
was structurally identical to the named six. Routing it uniformly
is the cohesive shape of the fix; leaving it as `.contains()`
would have preserved a known false-positive surface inside the
same file the fix targets. The "minimal fix, no surrounding
cleanup" constraint blocks opportunistic refactor, not the
uniform application of the named one-line substitution.
Verified: 8/8 in `design_schema_drift` green (was 7 + 1 compile-
blocking RED at c8c30d5); full ailang-core suite green; full
workspace `cargo test` green, no regressions.
Mirrors the inverse `strip_fences` pattern in
`crates/ailang-core/tests/design_index_pin.rs`.
