Tabrix v2.0.9
Tabrix v2.0.9 Release Notes
Release date: 2026-04-18
Context
v2.0.9 turns browser recovery from "state visible + manual advice" into a formal product loop: when a real browser automation request arrives and the bridge is not ready, Tabrix now attempts recovery and continues the original request when possible.
Added
- Unified bridge recovery guidance:
- one shared recovery guidance source now powers MCP tool failure payloads,
status,doctor, andreport. /statusbridge snapshots now includeguidance.summary,guidance.hint, andguidance.nextAction.
- one shared recovery guidance source now powers MCP tool failure payloads,
- Recovery-special smoke path:
tabrix smoke --bridge-recoveryinjects a bridge failure and validates that a real browser request either auto-recovers and succeeds or returns one single next action.
Improved
- Browser automation recovery loop:
- browser-tool requests now pass through one recovery gate before execution.
- bridge-degraded, bridge-broken, and command-channel-not-ready states now converge on one retry/recovery path.
- successful recovery now continues the original request instead of stopping after diagnostics.
- Diagnostics consistency:
status,doctor, andreportnow describe the same recovery truth with one action-oriented recommendation.- recovery failures now avoid multi-step manual suggestion lists and instead return one key next action.
- T3/T4 execution quality closure:
- T3.1/T3.2 structured
read_pagecontract is now used as the stable base for execution-oriented snapshots. - T4 public GitHub baseline remains runnable after Douyin private-asset split.
- workflow run detail baseline path now prefers explicit run URL navigation and dedicated tab resolution, restoring
workflow_run_detailbaseline stability.
- T3.1/T3.2 structured
Fixed
- Fixed product gap where recovery stopped at advice text even though runtime state was recoverable.
- Fixed inconsistent wording across
status,doctor, andreportfor the same bridge fault. - Fixed smoke acceptance gap by adding a formal recovery-specific validation path.
