A1. router.lua surface clean; classify_model is a natural sibling of
classify. No structural refactor.
A2. broker error message shapes confirmed: all transport errors carry
"transport: " prefix; "api: " for SSE-framed semantic errors;
"broker: " for config bugs. Fallback matcher must strip the prefix
before testing — list of eligible patterns tightened in §5.
A3. Q38 RESOLVED — summary doesn't go in ctx.turns (would create
system/system back-to-back, same gotcha as PHASE0 §6 user/user).
Instead lives on ctx.summary (string) and composes into the
system message between [background] and NORRIS suffix. No new
role:"system" turn; no alternation risk. §3 + §6 reflect.
Module-changes table updated to specify ctx.summary string field +
the to_messages composition order. Storage shape diagram in §6
rewritten.
