Omar SobhandClaude Fable 5.1	36af178980	rtx-cfd: overset_cfd1 RTX_OVERSET_ROWS — the overlap depth (patch rows kept non-hole below the acceptor row, default 4) as a knob for the §5.11 band probe; saved-field tags carry it; rows ≤ 3 are refused by the map at ny = 41 (acceptor donors reach the hole at the flag tip) ...

Omar SobhandClaude Fable 5.1	4c000266d9	rtx-cfd: overset momentum residual carries its pieces per ring face (time, convective, diffusive, pressure); overset_cfd1 offline probes on the saved fields — RTX_OVERSET_CFD1_FRONT dumps the cylinder-front faces by piece, RTX_OVERSET_CFD1_RAW re-evaluates the ring on the raw interpolated stamping without balance_fringe_fluxes (the balance is not the ring's source: +0.241 raw vs +0.247 balanced at ny = 41 upwind) ...

Omar SobhandClaude Fable 5.1	0215c7d6a5	rtx-cfd: CurvilinearPisoSolver::momentum_balance — the patch's own momentum balance on its solved cells in the scheme's fluxes (outward ρFu_f with the predictor's face value, Laplacian-form μ∇u·S on the solved/acceptor interface and the wall, the least-squares pressure volume sum vs the face-pressure integrals); flux_force, wall_force, pressure_defect δP; overset_cfd1 prints it and the acceptor band's mismatch, saves the patch flux, and RTX_OVERSET_CFD1_LOAD=dir runs the diagnostics offline on saved fields ...

Omar SobhandClaude Fable 5.1	e31576d543	rtx-cfd: OversetPisoSolver::solver_metric_force — the box force in the predictor's own flux form (upwind convective, diffusive, cell pressure on the momentum control volumes' faces, minus the unsteady term); box-independent to rounding in the active region (five boxes spread 2e-12 at step 5 vs the CV formula's ±0.5 %); overset_cfd1 prints wall − box = ring Σr + rest and saves the settled fields under RTX_OVERSET_CFD1_SAVE ...

Omar SobhandClaude Fable 5.1	6f9b0d43b2	rtx-cfd: OversetPisoSolver::momentum_residual — the background predictor's own staggered stencil (u_rhs/v_rhs, factored out of the predictor bit-identically) evaluated on every face of a NaN-masked field; solved faces read rounding, the active–fringe interface reads the composite's pressure level offset δ·h (cancels in the sum), prescribed fringe–fringe / fringe–hole faces read the stamping's momentum injection; hole ghosts (p, u, v) from a band widened three rows into the hole make every ring face evaluable; overset_cfd1 prints the buckets, the ring x-bands and δ at the settled state; pin: residual vanishes on the solved faces ...

Omar SobhandClaude Fable 5.1	cbec40b999	rtx-cfd: overset_cfd1 prints five CV boxes (all outside the fringe ring), the wall pressure/viscous split and the fringe extents at the settled state ...

Omar SobhandClaude Fable 5.1	134ac03870	rtx-cfd: OverlapMap::region_force — momentum flux into a background region (control-volume face formula, one-sided next to holes); overset_cfd1 prints the four momentum routes (CV box, ring outer, hole boundary, wall) and their defects at the settled state ...

Omar SobhandClaude Fable 5.1	5f780447de	rtx-cfd: PatchConvection::TvdVanAlbada — van Albada deferred correction on the curvilinear predictor (downwind-side linear weight, gradient-ratio r over the face d lengths, far-upwind across the opposite face, boundary faces upwind); annulus MMS orders 2.10/1.69 at 0.24× upwind; cylinder-flag MMS orders 1.98/1.97 (1.06× upwind — diffusion-dominated, recorded); knobs RTX_OVERSET_CFD1_TVD, RTX_OVERSET_MAX_ROUNDS, RTX_CF_SCHEME ...

Omar SobhandClaude Fable 5.1	02c855b9c4	rtx-cfd: overset Schwarz stall rule guarded (fires only within 10× the tolerance) — unguarded it cut CFD1's transient at round 3 every step and the coupled march diverged at ny=62 (pressure 4e4 → 1e140 by step 450); CFD1 harness knobs (stall, step cap, trace) ...

Omar SobhandClaude Fable 5.1	00f73eb70a	rtx-cfd: overset CFD1 harness — the steady-march stall rule (stall_rounds 2) actually enabled (the previous commit's edit had missed its anchor) ...

Omar SobhandClaude Fable 5.1	9761cf2319	rtx-cfd: overset P4 — CFD1 on the composite (tests/overset_cfd1.rs): ny=41 wall drag 15.2156 (+6.46%), lift 1.0879 (−2.78%), CV drag 15.528 (+8.64%), routes 2.0% apart (staircase +10%); 28550 steps, 2099 s at dt 4.57e-4 with 5.0 Schwarz rounds mean (stall rule off) — steady-march stall rule on for the next rungs ...
