Convert mock evidence into a transfer-tested IELTS repair system
Phase 6 adds an interactive transfer check, a priority repair queue and direct routing back to the relevant skill lab. A record stays open until the same error pattern is solved on a new lightly timed task.

Interactive transfer check
Tick the gates after a fresh task. The record closes only when all four are true.
3/4 gates selected
Do not close this error yet: explanation alone is not transfer evidence.

Evidence
The passage stated that the pilot was temporary, not the permanent system described in option B.
Cause
The learner matched topic vocabulary but did not check the limiting phrase.

PHNSpeakingMedium
The Part 2 answer was understandable but final consonants disappeared when the learner accelerated.
Evidence
Several past-tense endings and plural markers were not audible in the recording review.
Cause
The learner prioritised speed over articulation during the long-turn answer.
Repair action
Repeat the long turn with a slower first minute, final-sound marking and one timed retake.
