First step of the cognition control plane (docs/COGNITION.md). The chat turn is now
an explicit society of parts over a shared TurnContext blackboard:
perceive (stub) -> route (session mode) -> compose (tiered prompt) -> deliberate.
- lyra/mind.py (new): TurnContext + the pipeline + assemble(); moved build_messages
and the deliberation helpers here (the assembly belongs in the control plane).
- lyra/chat.py: slimmed to "speak + persist" — calls mind.assemble(), runs the
tool/generation loop, persists. No behavior change (same prompt, same output).
- tests: point test_time/test_chat at mind; add an assemble() structure test;
make test_chat/test_tools hermetic (CHAT_DELIBERATE off so respond() doesn't make
a real LLM call). Suite 86 green in ~5s, ruff clean, no import cycle.
This is the frame; perceive/route/learn get filled in next phases — each opt-in.

She had no clock: current date/time and the gap since Brian last spoke were
invisible between turns, and reflection was timeless. Now:
- lyra/clock.py: wall-clock stamp + coarse human gaps ("3 days")
- chat: inject a 'now' note (date/time + gap since last turn) after her
self-state — when she is, before the world
- reflect(): feed current time + silence gap into reflection, neutrally —
prompt invites her to weigh elapsed time "to whatever degree it genuinely
affects you" (no prescribed feeling; whether silence means anything is left
to emerge)
- memory.last_exchange_at(): timestamp of the most recent exchange
