📝 Walkthrough

Walkthrough

The specification updates provider initialization semantics so lifecycle events precede initialization termination, wait operations include event processing, migration guidance reflects the ordering, and spontaneous provider events are permitted.

Changes

Provider lifecycle contract

Layer / File(s)	Summary
Lifecycle event requirements specification.json, specification/sections/02-providers.md	Provider lifecycle requirements distinguish applicable transitions and require PROVIDER_READY or PROVIDER_ERROR before initialize terminates.
API wait behavior specification.json, specification/sections/01-flag-evaluation.md	Set-provider wait operations include both initialize termination and processing of the resulting lifecycle event, without waiting for application handlers.
Migration and event guidance specification/appendix-e-migrations.md, specification/sections/05-events.md	Migration guidance requires event emission before returning or throwing, and providers may emit spontaneous events without lifecycle methods.

Estimated code review effort: 2 (Simple) | ~10 minutes
