/**
|
|
* Regression guard for B-GCF-QUOTE (lossless violation).
|
|
*
|
|
* SPEC §2.4 requires quoting a string that contains the inline-array pattern `[`…`]``:`
|
|
* (e.g. `ERR[404]: Not Found`, `[Speaker 1]: Hello`). needsQuote() lacked that rule, so
|
|
* such a value emitted bare on a line-level `key=value` RHS is re-parsed by the decoder
|
|
* (decode_generic.ts:142-160) as an inline-array header → throws `count_mismatch` (or
|
|
* silently decodes wrong). Reachable in prod: headroomEngine.apply() ships the blob.
