James PineandClaude Opus 4.7 c9103a24da fix(mcp): stamp last_seen_at on /speak too + tighten path predicate
POST /speak is a REST wrapper around voicebox.speak for agents that
don't talk MCP (shell scripts, ACP, A2A). It reads X-Voicebox-Client-Id
and uses it for the same per-client profile resolution + default
personality lookup the MCP tool does (speak.py:39-64), so its callers
are first-class clients — but the ClientIdMiddleware only stamped
last_seen_at on /mcp* paths. REST speak callers showed up as "never
seen" in Settings → MCP despite actively acting on their bindings.

Widen the stamp predicate to an explicit ("/mcp", "/speak") prefix
list, and require a path boundary on match so future routes named
/mcpfoo or /speakers don't silently inherit the stamp via the prefix.
New test_client_id_middleware.py pins the scope with 17 parametrised
cases (both the allowed set and the overlap cases that must not match).

"""Unit tests for the ClientIdMiddleware path predicate.
Locks down which endpoints advance ``last_seen_at`` on the
``MCPClientBinding`` row. Getting this wrong is silent: the Settings UI
just shows a stale "last heard from" timestamp and bindings never get
auto-created for new REST callers.
