I don't think it's explicit anywhere, so this is just my own interpretation: I think it came into being only once the RMN started modernising, under King Roger. There wasn't a point in talking about new tactics and new techniques when there wasn't anything new in terms of weapons and construction. And there hadn't been in 3 T-centuries. The advent of the laserhead only happened part-way through Project Gram's existence.
Oh, there must have been some fringe elements who always advocated for new things. The lieutenant who had envisaged a two-stage missile when Travis Long was going through basic training is one example: as far back as the 1530s, there would have been people thinking of new ways. But they would have been a definite minority and mostly ignored because their ideas couldn't be put into practice.
Travis wouldn't consider himself anywhere near revolutionary. He was a by-the-book guy who just happened to have bursts of inspiration and thought outside the box when needed.
We don't know what in Sonja attracted Prince Roger and Captain Adcock to have them recruit her into Project Gram. I expect she'd already demonstrated the capacity for thinking outside the box and -- like Shannon later but unlike Travis -- use it at will, not just under pressure. Her way-above-average intelligence would have been a known fact. And her personality would have guided her to shore assignments with like-minded people she wouldn't easily offend.
So I expect the jeune école wasn't relevant until the mid-1870s or so, if it existed at all. But once the laserhead became known and some hints of progress from Project Gram made their way to the RMN personnel, it did take root.
I think you might be overstating the lack of new weapons and technology over the proceeding 3 centuries. From IIF we know that impeller missiles (first prototypes 1246 PD followed "soon" by "smaller more practical drives"), sidewalls (1260s? PD "roughly a decade after [practical?] impeller missiles], sidewall penetrators (1298 PD) are all well beyond 3 centuries old.
But now "The stage was now set for an arms development race that has continued for the last seven hundred years. Military spacecraft designers devised increasingly effective ways to deceive, destroy, or block the attacking missiles. Weapon designers invented increasingly effective seekers, sidewall penetrators, and warheads. The evolutionary development over the period between about 1300 and 1800 was sometimes punctuated by bursts of revolutionary activity that introduced competing technologies on both sides of the offensive/defensive divide." [IFF]
Next on mentioned is still more than 3 centuries old; the inertial compensators (1412 PD)
From HoS we know Manticore's first Dreadnoughts (design licensed from the League) were commissioned in 1632 PD. -- At some unspecified point in the ensuing century compensator technology improved sufficient to permit the construction of Superdreadnoughts; with Manticore commissioning her first in 1742 PD.
Back to IFF:
Pure fusion (grav pinch) warhead (1650s PD) -- allowing warhead's of unheard of yields to be fitted into missile bodies (allowing them to overload and burn out sidewalls).
Altering fusion fuels to gain a bit of standoff range and tune the resulting radiation (1669 PD)
Impeller drive counter missile (1701 PD)
Point defense laser weapons (1780s PD)
nuclear gravitically directed energy weapon (NGDEW) (1806 PD) -- improved direction shaping and increased standoff range for sidewall burning warheads.
RMN achieves 8-10,000 km warhead standoff range for sidewall burning (1826 PD)
First trial laserhead warhead (1833 PD)
First complete laser-head-armed impeller-drive anti-ship missile system (1866 PD)
Project Gram might technically have predated that last, but if so only barely. The Project was initialed by King Rodger III and he wasn't crowned until 1857 PD.
And Manticore had been working to some degree on laserheads since the 1930s PD; basically contemporaneously with Astral's first (failed) SLN live fire trials in 1933 PD and came out with their fist one (the Mk 19 capital ship missile) in just 1870 PD. (And just 9 years later started designing the Mk13 CA/BC weight missile which managed to scale the warhead down to fit while also shoehorning in a multi-mode boom/burn/lase capability)
And of course glossed over in that list is a steady back and forth of advances in ECM, jammers, decoys, sidewalls, sidewall penetrators, warheads, point defense autocannon, improved laser clusters, steady upward creep in maximum compensator tonnage, etc. etc., each temporarily tilting the advantage towards attack or back to defense. All of that is enough innovation within the stagnant tactical "plateau" that you probable had more than just the fringe feeling that some new design, fully buying into the latest advance, might shake things up and provide a major advantage.
So if not a full blown jeune école movement during that whole period there was probably always at least the nucleus of such a movement within the RMN and it would have waxed and waned in size and influence through the many decades. (Though when such a group fist actually adopted the name "jeune ecole", from the French 19th century CE strategic naval concept, for themselves is unknown)
