SST OpenCode v1.15.5 (May 18) introduces an experimental OpenAI native runtime path (preview), adds `--replay` and `--replay-limit` flags to view recent session history during interactive runs, fixes plugin tools using the `ask` function so tool calls complete correctly, reduces subscription race conditions causing missed /event updates, sorts the v2 session list by most recently updated, and refreshes the TUI prompt layout after pasting content.

Why it matters

The experimental OpenAI runtime path is a significant architectural addition for users running OpenCode against OpenAI's infrastructure. The --replay flag enables debugging and auditing of past agent sessions without leaving the TUI.

Importance: 2/5

Experimental OpenAI runtime path added; --replay flag for session history; follows v1.15.2–4 critical async context fixes from yesterday
