Convergence Monitoring

Iteration 1:  ████████████████████████████████████████  300 lines changed
Iteration 2:  ████████████████                          120 lines changed
Iteration 3:  ██████                                     40 lines changed
Iteration 4:  ██                                         10 lines changed (cosmetic only)
              ^--- Convergence reached: the diff shrinks each pass until only cosmetic changes remain

Convergence:  Agent is DONE      -> small diffs because work is complete
Ceiling:      Agent is STUCK     -> small diffs because agent cannot proceed

Check 1: Are tests passing?
  YES, and improving -> Convergence
  NO, stuck at same failures -> Ceiling

Check 2: Is the agent trying new approaches?
  NO, just polishing -> Convergence
  YES, but they all fail similarly -> Ceiling

Check 3: Are there BLOCKED tasks in impl tracking?
  NO -> Convergence
  YES -> Ceiling (read the blockers)

Check 4: Is the agent producing meaningful error messages?
  NO, just minor changes -> Convergence
  YES, about dependencies/tools/access -> Ceiling

Non-convergence:
Iteration 1:  ████████████████████████████████████████  250 lines changed
Iteration 2:  ██████████████████████████████████████    230 lines changed
Iteration 3:  ████████████████████████████████████████  260 lines changed
Iteration 4:  ██████████████████████████████████        220 lines changed
              ^--- NOT converging: changes are flat/oscillating
