Omar SobhandClaude Fable 5.1	8c130c55c8	PERF-2 P2-c: RTX_FSI2O_INNER_STOP knob — the background Poisson's inner stop as a multiple of the Schwarz tolerance (default 0.1; the band-gated ladder on the CG iteration count) ...

Omar SobhandClaude Fable 5.1	7f144e0005	PERF-2 P2: the red-black colour maps, the residual and the V-cycle's per-level maps on rayon threads (MultigridParameters::threads; RTX_THREADS in the harness; rtx_cfd::configure_threads) — each colour's values computed from the unchanged other colour into a scratch and written back, the L1 sum in the serial order: bit-identical to the serial red-black (pin: 4 right-hand sides at 4 threads); the coarsest level stays serial; no effect on the lexicographic regime ...

Omar SobhandClaude Fable 5.1	cb5771fa71	PERF-2: red-black symmetric Gauss–Seidel smoother behind a knob (MgSmoother::RedBlack; default lexicographic = the recorded regime, bit-identical) — red/black cell lists per level, the symmetric pair red,black,black,red, the operator cache keyed on the smoother; EmbeddedParameters::poisson_smoother, harness knobs RTX_FSI2O_MG_RB (overset) and RTX_FSI2_MG_RB (embedded, the noise probe); pin: solves the masked problem to the same stop, agrees with lexicographic to 2e-12, cached = uncached bit for bit ...

Omar SobhandClaude Fable 5.1	1547d14ff1	PERF-2 P0-b: CG iterations per Poisson solve in the profile (ms per V-cycle) and sub-timers inside the patch regeneration (outline, hull + offset, ring projection, Winslow sweeps, respace, warm bookkeeping, mesh finalisation) ...

Omar SobhandClaude Fable 5.1	172a26dee4	PERF-2 P0: intra-step profiler — StepTimers on the overset solver (RTX_PROFILE; overlap build / predictors / patch BiCGSTAB / background Poisson with its setup-vs-iterate split / round exchange / apply / end exchange), PoissonSolution carries setup_ns and iterate_ns, the harness times advance / restore / snapshot / load sampling / force / FEA predictor and prints the wall split of the coupled phase; no clock is read when profiling is off; the reclassified/step progress denominator fixed (was ×4) ...

Omar SobhandClaude Fable 5.1	c3dbd5040a	P6-b design 2: the Robin wall on the patch's Inner side — RobinWall { alpha, datum } with the wall velocity u_s + (t_f − datum)/α (explicit, damped by the wall's own viscous gain μ/(α d)) and the compliant-wall pressure term |S| p'/α implicit in the projection (the added-mass operator in the fluid's own response); Dirichlet bit for bit when off; MMS pin on the skewed annulus (orders 2.46/2.13 at α = 10 and 100 μ/h, the Dirichlet values; a 1e12 wall reproduces Dirichlet to 2e-6); OversetPisoSolver::patch_mut; harness knob RTX_FSI2O_ROBIN_ALPHA with the previous pass's tractions as the datum, printed in the header ...

Omar SobhandClaude Fable 5.1	415c32ab04	overset mesh: the flat-tip outline (P5-3 option B) — cylinder_flag_outline_deformed_tip / cylinder_flag_patch_deformed{,_from}_tip take the tip's corner radius (t = the recorded semicircle, bit for bit; smaller = the benchmark's flat face between corner arcs sampled at the wall spacing, point count fixed across the deformation, the tip's corners kept off the hull source); pins: corner t reproduces the recorded outline, the 2.5 mm outline has the exact area excess with no collapsed spacing, the O-grid builds straight and at ± 80 mm cold and warm at ny 41/62; harness knob RTX_FSI2O_TIP_CORNER (default 0.01) on the cold and warm builds, printed in both headers; pinned-toolchain fmt on touched crates ...

Omar SobhandClaude Fable 5.1	0645565bd8	fsi2 harness: RTX_FSI2O_FILLET knob (the outline's fillet radius, 5 mm = t/2 in every recorded run: a half-round tip and 5 mm root fillets vs the reference's sharp rectangle; printed in both headers) — P5-3's first problem-definition probe after the h-term was traced to the wake's strength on the background ...

Omar SobhandClaude Fable 5.1	c63115053b	fsi2 harness: RTX_FSI2O_PATCH_STRETCH knob (the patch's across stretch, 4.0 in every recorded run; printed in both headers) — P5-3's wall-normal resolution test at fixed h: the rows ladder does not build (the overlap needs outer patch cells ≈ h/2 or larger), the stretch refines the wall cell 0.227h → 0.144h → 0.088h at 4/8/16 while the outer cells grow ...

Omar SobhandClaude Fable 5.1	c7d2870580	fsi2 harness: RTX_FSI2O_BG_CONVECTION knob (tvd default / upwind) on the background, printed in both headers beside the patch's — the patch scheme was excluded as the h-term's carrier (upwind ladder +1.52 vs TVD +1.73 W/m from ny 41 to 62), the background's wake dissipation is the registered next probe ...

Omar SobhandClaude Fable 5.1	ff7cc2d739	fsi2 harness: RTX_FSI2O_PATCH_CONVECTION knob (tvd default / upwind / none) on the overset patch, printed in the march's coupling header and the replay's PRESCRIBED header — P5-3's near-wake dispersion test on the ny 62 fixed-motion replay; harness files under the pinned toolchain's cargo fmt ...

Omar SobhandClaude Fable 5.1	7e13d14e96	FSI2 overset harness: RTX_FSI2O_DT_SCALE scales the CFL-derived fluid step — P5-3's dt-convergence probe of the first-order Euler fluid steps (the band's placement is excluded: 94.0 mm at a 60 mm patch vs 94.8 at 40 mm; the s = 8 pair moved the amplitude 95 → 60 mm) ...

Omar SobhandClaude Fable 5.1	3e019d1491	P5-3 instruments: per-region wall loads on saved instants (top / bottom / tip arc / fillets+cylinder — drag, lift, normal-traction mean/min/max; RTX_FSI2O_AUDIT_FACES, RTX_FSI2O_AUDIT_ONLY) and the patch-thickness knobs (RTX_FSI2O_PATCH_OFFSET / _PATCH_ROWS, RTX_OVERSET_PATCH_OFFSET / _PATCH_ROWS; save tags carry the offset) — the overlap band sat at a fixed number of cells (6 h) and moved inward in metres with refinement ...

Omar SobhandClaude Fable 5.1	2c1143076e	P5 audit exact on the moving path: the composite rebuilt around a saved instant carries the march's dt (from the mesh the march started on — the warm base under RTX_FSI2O_WARM_SWEEPS — whatever patch the instant holds; 0.2 % of dt read as 0.3–5 N/m of solved-face residual), and instants save dt; over 131 instants of the FSI2 march to t = 16 s the solved-face residual is 1.7e-10 at every one ...

Omar SobhandClaude Fable 5.1	06229dd9a2	rtx-cfd: the deformed cylinder–flag build's hull source carries the deformed outline — the cylinder + tip disc alone give the chord under a bent flag's convex side (P5-2 died at tip −35 mm with the patch 4.4 h thick where 6 h was asked, an acceptor's donor on a prescribed face); the death reproduced from the last saved instant by extrapolating the interface (fsi2_overset_probe_death_from_instant, with the failing acceptor's ray geometry and the overlap depths that build) and gone with the fix at every τ; RTX_FSI2O_ROWS; the zero-displacement mesh gate at 1e-5 (the pipeline's), the outline gate 1e-12 unchanged ...

Omar SobhandClaude Fable 5.1	3c2add3f32	P5 audit: the overset march saves the composite at every N-th committed step (RTX_FSI2O_SAVE_EVERY: background, the deformed patch's nodes, its vectors, d, ddot, time), and fsi2_overset_audit_of_saved_instants (RTX_FSI2O_AUDIT=dir) rebuilds the composite around each saved patch (build_case_with an initial mesh, so the overlap is the instant's) and prints the solver-metric chain — the CFD23 instrument on the moving patch ...

Omar SobhandClaude Fable 5.1	3a68048934	rtx-cfd: cylinder_flag_patch_deformed_from — the warm-started regeneration (P5's cost lever): the previous patch's interior and its outer ring projected onto the new offset polygon as the start, and an IDEMPOTENT build (one Winslow sweep alternating with the ray re-spacing; the P4-0 one-shot is not a fixed point — measured as the interior moving 0.05 h per build at rest), so a base converged as that map's fixed point stays put (9e-11 h at rest) and each build tracks the outline (interior/wall motion 0.99–1.14, worst angle 74.7°, wall row 0.37 h) 4.5× faster than the cold build; the rigid generator untouched (pins pass); fsi2 overset harness: RTX_FSI2O_WARM_SWEEPS with the converged base as the initial patch and the committed step's mesh as each step's warm start ...

Omar SobhandClaude Fable 5.1	565215baf9	P5-1 instruments and discriminators: RTX_FSI2O_NO_WALL_VEL, _FREEZE_PATCH, _VOLUME_PRESERVE (the imposed wall velocity's net flux removed uniformly along the wall), the pass trace carries the fluid's power on the flag, the wall-pressure roughness, the patch's pressure level, the wall's net volume flux against the FEA polygon's area rate, and the mass defects — the s = 1 runaway is the flag's thickness breathing (ν = 0.4 Quad8) seen by the body-fitted wall as a volume flux equal to the polygon's area rate, answered by the projection's pressure level at ρ/dt ...

Omar SobhandClaude Fable 5.1	2ed36c3a8c	P5-1 instruments: the overset fluid saves/loads its rigid-phase state (RTX_FSI2O_SAVE / _LOAD — a coupling experiment then costs seconds, not the 12-minute rigid march), dumps the interface edges when the composite refuses a patch (RTX_FSI2O_DUMP_DIR, at the advance where the overlap is rebuilt), the release time is the fluid's clock; patch_cylinder_flag_deformed: cells inside the flag are holes at small bends and both sweep counts (the cantilever shape does not reproduce the P5-1 death — the CSVs show a coupling runaway), and a dumped-edges reproduction test ...

Omar SobhandClaude Fable 5.1	d74571e21a	rtx-cfd: the deformed cylinder–flag outline's edge fractions come from the UNDEFORMED straight edge (x_tip_ref), so the patch topology is the mesh family's and not the deformation's — the P5-1 gate run died at the first bend with set_mesh refusing 143 → 144 wall cells; the P5-0 test now gates ns across amplitudes (143 at −80 / +40 / +80 mm) ...

Omar SobhandClaude Fable 5.1	f0b2563bf8	P5-1: FSI2 with the fluid on the overset — fsi2_harness/overset.rs (the background without a body, the cylinder–flag patch regenerated around the deformed flag every pass via set_patch_mesh, the wall velocity from the interface velocities along the wetted polygon, the load from the patch's wall faces into WettedSurface::transfer_load — no probes, no clamp, no smoothing), fsi2_harness/overset_march.rs (the harness's rigid phase / release / subiterated coupling with its acceptance rule, no rescue machinery, death returned not panicked), tests/turek_hron_fsi2_overset.rs (RTX_FSI2O_* knobs); rtx-cfd: CurvilinearPisoSolver::wall_tractions (per-face pressure + full-stress traction, surface_force sums the same terms bit-identically); Interface::edges (bottom/tip/top for the generator); cylinder_flag_mms RTX_CF_BEND (P5-0 gate iv: Stokes orders 2.14 / 2.09 on the flag bent to 80 mm) ...
