Havret, who won the Scottish Open last year, has led from round one
France's Gregory Havret ignored the Ryder Cup manoeuvrings behind him to maintain the lead of the Johnnie Walker Championship at Gleneagles.
Havret carded a third-round 69 to reach 10 under, one shot ahead of England's Anthony Wall, who fired 65.
Soren Hansen virtually assured his Ryder Cup place with a 68 to join the group on nine under with Lee Westwood.
Justin Rose should also be safe at eight under but Oliver Wilson's spot is still under threat from Nick Dougherty.
Wilson occupies the 10th and final automatic position for Nick Faldo's European Ryder Cup side ahead of Sunday's cut-off, but fellow Englishman Dougherty can overtake him if he finishes in the top two in Scotland.
The culmination of a year's worth of golf comes down to one day
If Dougherty does get to second place on his own Wilson will still edge him out of the team if he finishes 27th.
"I'm enjoying the challenge and I'm delighted to still have a sniff," said 26-year-old Liverpudlian Dougherty. "Ollie's favourite, but I'll see if I can make him sweat a bit.
"It's a big day. The culmination of a year's worth of golf comes down to one day.
"I played wonderfully today and made nothing. The longest putt was the five-footer on the last."
Wilson, who admitted to a sleepless night, said: "I was so tired first thing. I put so much into the first two days, but then woke up around 2am wide awake.
"I got back to sleep about 5.30am and then woke up again at six. But I played nicely and I'm in a good position now."
England's Ross Fisher, the only other man who can clinch an automatic spot if he finishes in the top three, carded 73 for level par overall.
Rose and Hansen, at eighth and ninth respectively on the rankings, should have done enough to claim Ryder Cup debuts in September.
"I said to myself this morning I'm not going to think about the Ryder Cup any more because it would take a minor miracle for something (bad) to happen," said Rose.
Of those still scrapping for one of two wildcards after Sunday's final round, Darren Clarke was one under after a second successive level-par 73, while Colin Montgomerie slipped to one over after a 76.
English pair Paul Casey and Ian Poulter are the other players being touted as wildcard candidates, but they are playing in America.
Ireland's Paul McGinley, who relinquished his role as Faldo's assistant to concentrate on qualifying but fell short, ended four under but is unlikely to be handed a wildcard, though Faldo may re-issue the vice-captain invitation.
