Follow-up to the salvaged #96379 commits: the fallback verdict is computed once
(`accepted = api_mode in chat modes`), the warning says what actually happened
("accepted without verification" vs "was not saved") instead of promising a
save it then refused, and the contributor's ten regression tests collapse to two
parametrized invariants (chat modes persist unverified; other modes still reject;
a reachable catalog stays authoritative).
Allow custom chat-completions endpoints without a usable model catalog to persist explicitly requested model IDs with the existing verification warning.
Internal moves get no re-export aliases: models_validate reads
hermes_constants.openrouter_variant_base directly and the private
_OPENROUTER_VARIANT_SUFFIXES/_openrouter_variant_base shims are dropped.
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
