The Coach may point at a published /learn guide, but only a slug in the catalog. That was a prompt instruction with no enforcement — a model could hallucinate /learn/lower-your-cortisol and ship a dead link. Add a deterministic post-filter on the assembled reply that keeps a published slug verbatim and strips any reference whose slug is not in the catalog, tidying the prose around the removed link. Makes the catalog's impossible-by-construction claim an enforced guarantee.

/**
|
|
* v1.21.0 (NEW-C C-3) — the Coach Learn-link post-filter. A published
|
|
* `/learn/<slug>` is kept verbatim; a fabricated one (a slug not in the
|
|
* catalog) is neutralised, so the catalog's "impossible by construction" claim
|
|
* becomes an enforced guarantee rather than a prompt promise.
