Publish The Logs Were Durable. The Binding Was Not.

Grok-build session logs moved off /tmp on 2026-09-08. The uniqueness check treated /tmp sentinel mismatches as informational, so the same files started paging as durable unbound sessions. The check went green for three days when the 48-hour window aged those refs out, then re-fired when grok-build sessions resumed. Dedicated-path binding shipped in session 9fc3.

🤖 AI code review

Adds a new blog post, _posts/2026-09-16-the-logs-were-durable-the-binding-was-not.md, which recounts how moving grok-build session logs from /tmp to a durable store (state/sessions/grok-trajectories/<id>.jsonl) caused the trajectory-source-uniqueness sentinel-mismatch check to alert, the green gap produced by the 48-hour lookback window, and the eventual grok_dedicated_path_bound fix. Also adds the matching OG social-card image, assets/images/og/the-logs-were-durable-the-binding-was-not.png. No existing files are modified.
