2026.08 · VALIDATION
A safety filter added in July — the velocity D-term low-pass that contains estimator-step thrust spikes — quietly cost settled waypoint precision, 0.05 m to 0.08 m, and the 1.5 m sim gate never noticed. A pinned-environment bisect found it; halving the filter time constant kept ~13x spike attenuation and returned 0.03–0.07 m. Every validation gate across the three sims is now calibrated to the measured seed-sweep envelope at roughly 3x the worst observed run — margins that mean something, recorded next to the assertions they bound.
2026.07 · MISEAN
Las trì lasaidhean ann am meadhan misein cuairt ath-nuadhaichte den raon sgrùdaidh. Chaidh na trì aithneachadh, dearbhadh, agus leasachadh le cuairt gu fèin-riaghailteach — dàilean de 0.4, 24, agus 40 diog bho lasadh, air an comharrachadh gu 0.14m. Dh'fhan an stiùireadair air an tuairmse fad an t-siostam gu lèir.
2026.06 · SEÒLADAIREACHD
Chum NIGHTJAR mearachd àirde 0.78m air sruth optaigeach, baraiméadar, agus magnatamadair a-mhàin tro uinneag ceilte ann am meadhan misein. Dhiùlt gèata ùr-ghnàthachaidh na leumannan coltach ri foill gu dìreach.
2026.05 · FÈIN-RIAGHLADH
Dhearbh CUSTOS trì conaltraidhean talmhainn agus dh'itealaich e gu fèin-riaghailteach cuairt le mothachairean beò timcheall gach fear gus comharrachadh a theannachadh fo 0.31m CEP, agus lean e air an t-sireadh.
2026.04 · DEUCHAINN ITEALAICH
Bidh sruth optaigeach a' tuiteam fo 0.3m AGL, agus mar sin bidh lorgaire an laighe a-nis a' cleachdadh àirde a-mhàin — a' cur crìoch air an fhrith-bhualadh conaltraidh a chaidh fhaicinn ann an turasan roimhe.
ORIGIN · HERITAGE
Before any of this was an autonomy stack, there was a sun conure on the Red Sea shore at Suez. It would launch, work its own arcs over the water, and come back to hand: loiter, maneuver, return, flown on instinct. SIDRA is that instinct, engineered. Callsign: ARATINGA.
