Tack v0.19.0: Release Readiness Calibration

Version 0.19.0 calibrates Tack for the next Inner Circle deployment. The focus is precision at the edges: what shared recipients can see, how regenerated outcomes settle into the record, and when the live conductor yields to fallback transcription.

Private by Construction

• Host-Only Transcript Boundary: Shared links now present the polished meeting workspace while keeping raw transcripts, speaker labels, and live-only internals reserved for the meeting owner.
• Composed Shared Summaries: Recipient views continue to show the structured outline, summary, decisions, action items, and canvas without carrying private capture material into the public surface.

Regeneration That Lands Immediately

• Instant Recap Refresh: Regenerated summaries now update the visible recap as soon as the server returns, keeping the review flow synchronized without a manual page reload.
• Settled Re-Extraction: Re-extracting outcomes on ended sessions now enriches the record quietly, without replaying live-only drift prompts or transition events into a completed meeting.

Live Fallback Discipline

• Stable Watchdog Timing: The realtime conductor watchdog now runs on a steady interval and evaluates live activity from render-synchronized signals.
• Reconnect-Aware Failover: Mid-session connection recovery receives its full inactivity window before the workspace transitions to chunked transcription, preserving continuity without premature fallback.
