    "**Model-relative, not silicon.** The certified object is the rank-1 coherent field-matching residual `1/2||G1(z) m - t||^2` under this repository's SOCS optics. It is a genuine lower bound over a box containing every binary mask of the declared class, and it is NOT a bound on the full non-convex SOCS-intensity problem, which is NP-hard and which no mechanism here touches. Every 'no mask can' in this report carries that qualifier.",
    "**`rho` is not EPE.** The spec is a relative field residual because that is the quantity the bound is on. Floor-to-EPE is not sound in general (residual energy can live off-contour), which is why the EPE channel is advisory and cannot set a verdict. A designer who wants nanometres does not get them from this certificate.",
    "**`rho_max = 0.28` is a declared budget.** It was chosen so that both verdicts are reachable inside the lattice -- 32 nm unprintable, 40 nm printable -- not measured from any process. Every design rule in part F is a rule *at that budget*, and the sentence says so.",
    "**The cost model is declared, not derived.** Ranking '+0.02 NA' against '-1.5 nm wavelength' needs a preference no physics supplies. `COST_PER_STEP` states one in the open. The per-axis minimal-step table is the measurement; the single winner is that table read through the preference, and both are in the artifact.",
    "**The process-window mechanism is sound and, here, worth nothing.** U1 is maximised over a declared weight family that contains the point masses, so it can never be weaker than the best single-defocus floor -- and on every spec measured no multi-node weighting was strictly stronger either (B3). The window still enters the answer through the *witness* side, which is scored worst-over-nodes. Reported as the null it is.",
    "**Dose latitude is out of scope and is named, not approximated.** Dose scales the aerial intensity; the certified object is a field residual and there is no dimensionally honest way to write a dose perturbation into it. `ProcessWindow` carries defocus only.",
    "**The lattice is finite, so 'unreachable' means unreachable on it.** An axis that does not reach feasibility within its declared steps is reported as `unreachable` with its terminal verdict, and the pair probe in D2 reports its own budget. 'No pair found in N evaluations' is not 'no pair exists'.",
    "**One spec, one raster.** The non-monotonicity in C4/C5 is measured at `grid=128, pixel_nm=1.0` on this feature family. It is enough to refute the monotonicity assumption a bisection needs -- one counterexample is all that takes -- and it is not a characterisation of how non-monotone the objective is in general.",
    "**The eigen-phase fix this item needed was a defect in committed code, and its blast radius is wider than F6-05.** `socs_linear_operator` handed out a field operator whose global phase came straight from a Hermitian eigendecomposition, i.e. arbitrary. Measured over 15 `(na, sigma_out)` points, 5 came back with a negative DC gain, and at those points the 'certified floor' for a 32 nm grating read 1.0 -- 'no mask can do anything' -- purely from the sign. Every consumer of the rank-1 *field* proxy was exposed; every intensity consumer was not, because `|A_k m|^2` is phase-invariant. Fixed at the class location with the convention documented there."
