v0.15.9 - 2026-08-31

Release Notes

Added

• agentty: persist Concise, Balanced, and Detailed response styles per session and
  project default, with /style selection and provider-neutral turn guidance.

Changed

• agentty: exchange focused-review findings as structured JSON across the shared
  protocol, provider prompts, and application UI.
• agentty: preserve completed file and inline Diff comments across mode changes until a
  new turn starts or the session is deleted.
• agentty: render only visible transcript rows while preserving cached wrapping and
  paragraph semantics.
• ag-harness: validate all structured model output against request schemas and content
  limits without allocating a second full-size JSON representation.
• docs: make short, conceptual documentation the repository default.
• quality: require Agentty E2E, diff-coverage, and coverage hooks before handoff.
• release: bump workspace crate metadata and lockfile package versions to 0.15.9.
