ThreadBack AI v1.2.0 — Local AI Intent Engine

Continuous local AI intent management with bundled BGE-small-en-v1.5 INT8: page-to-task assignment and task-to-task semantic reconciliation, automatic duplicate-task merging, conservative splitting, latent one-off handling and expiry, stale-task archival and archived-task reactivation. Grounded workflow renaming and bounded action history with safe Undo are included.

Fully offline semantic inference: no remote AI, API key, backend or telemetry. Durable MV3 pending-event recovery preserves browsing events through worker termination.

Verified: 197 tests passed; typecheck, lint, build, packaging and security checks passed. Actual unpacked Chromium: 31/31 checks, including worker recovery with 0 lost and 0 duplicate events. Ten same-purpose pairs, ten close-but-different pairs and twenty curated generalization flows passed; these are engineering fixtures, not universal accuracy estimates.

Known limitations: broad/acronym research may remain split. Automatic splitting currently requires fully represented tasks of at most five pages. Embedding similarities are not calibrated probabilities; semantic mistakes remain possible. Installed Chrome/Edge distributions and exact RAM usage were not independently qualified.
