 - Tools/web_search: handle xAI Responses API payloads that emit top-level `output_text` blocks (without a `message` wrapper) so Grok web_search no longer returns `No response` for those results. (#20508) Thanks @echoVic.
 - Agents/Failover: treat non-default override runs as direct fallback-to-configured-primary (skip configured fallback chain), normalize default-model detection for provider casing/whitespace, and add regression coverage for override/auth error paths. (#18820) Thanks @Glucksberg.
 - Docker/Build: include `ownerDisplay` in `CommandsSchema` object-level defaults so Docker `pnpm build` no longer fails with `TS2769` during plugin SDK d.ts generation. (#22558) Thanks @obviyus.
+- Docker/Browser: install Playwright Chromium into `/home/node/.cache/ms-playwright` and set `node:node` ownership so browser binaries are available to the runtime user in browser-enabled images. (#22585) thanks @obviyus.
 - Hooks/Session memory: trigger bundled `session-memory` persistence on both `/new` and `/reset` so reset flows no longer skip markdown transcript capture before archival. (#21382) Thanks @mofesolapaul.
 - Dependencies/Agents: bump embedded Pi SDK packages (`@mariozechner/pi-agent-core`, `@mariozechner/pi-ai`, `@mariozechner/pi-coding-agent`, `@mariozechner/pi-tui`) to `0.54.0`. (#21578) Thanks @Takhoffman.
 - Config/Agents: expose Pi compaction tuning values `agents.defaults.compaction.reserveTokens` and `agents.defaults.compaction.keepRecentTokens` in config schema/types and apply them in embedded Pi runner settings overrides with floor enforcement via `reserveTokensFloor`. (#21568) Thanks @Takhoffman.
