Add the shared contract the reasoning release builds on, with no change
to how a turn runs today.
- Schema: operator reasoning controls on app_settings (0376), the
encrypted trail text on coach_messages (0377), and source,
last_used_at and source_message_id on coach_facts (0378).
- Provider contract: CompletionParams.reasoning and onReasoning,
CompletionResult.reasoning and providerState, AiMessage.providerState.
- Reasoning levels, thinking budgets and the background-job table in
src/lib/ai/reasoning/levels.ts; coachPrefsJson.reasoning, absent
meaning medium, salvaged field by field like every other pref.
- Stream: activity, memoryNote and planProposal frames, done.stop and
done.withheldResults, result.interim, a compare chart kind, eight
table refs, three more clarification kinds with an assumed choice,
the change_assumption chip, and assumptions, activity, stop,
memoryNote and planProposal on the provenance. Zod mirror, type
parity and the native-client key rule cover every new frame.
- Chat request: memoryDecision and planDecision, parsed and not yet
acted on.
- Stub contracts for the memory functions and the activity recorder,
inert until their implementations land.
- Backup, restore and rotation carry the new columns; a fact's message
reference is resolved against the restored messages like its
conversation reference.
- Message keys for the trail, memory, plans, assumptions, replies,
interim tables, comparison charts and reasoning settings in all seven
locales, each reachable from a catalog and checked both ways.
