\caption{Model layer at the audited commit. The reference path targets the Anthropic Messages API;
adaptive extended thinking is enabled only for the models listed as supporting it. OpenAI and
Google models are served through an OpenAI-compatible adapter that receives the first 128 tools of
the 245-tool catalogue. Model identifiers are reproduced verbatim from the client configuration
(\texttt{client/src/lib/models.ts}); the Anthropic identifiers were checked against the provider's
current model list, the others were not audited.}

\item \textit{Notes.} Per-response generation is capped at 64{,}000 tokens and the temperature is
set to~1 on the reference path; the summarisation call of Algorithm~\ref{alg:context} uses a cap
of 2{,}000 tokens and a temperature of 0.5. The Beamer restructuring call
(Section~\ref{subsec:docs}) is pinned to \texttt{claude-opus-4-8} irrespective of the selected
model. Cost is computed from a single fixed schedule (\$3 per million input tokens, \$15 per million
output tokens) for every model, so the ledger does not reflect per-model prices
(Section~\ref{subsec:accounting}).
