Remark 9.3.11 asked whether the AdherentPt hypothesis could be removed from Proposition 9.3.9 and subsequent theorems. Formalization confirms it can. This removes AdherentPt from 17 theorem statements (keeping it only in Convergesto.uniq where it is genuinely needed). Other statement fixes: - Example 9.3.2 constants: 5 → 5.1, 0.41 → 0.42 (needed for strict <) - sq, linear, quadratic: fix argument order (limit before point) - const, id, sq, linear, quadratic: implicit → explicit args - const body: fun x ↦ c → fun _ ↦ c Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
…At.comp typo Follow-up to the AdherentPt removal: once `AdherentPt.of_mem h` is no longer called in the bodies of `ContinuousWithinAt.add/.sub/.max/.min/ .mul'/.div'`, the `(h : x₀ ∈ X)` hypothesis is unused. Drop it. Same cleanup for `Filter.Tendsto.comp_of_continuous` and for `ContinuousWithinAt.tfae` (also makes `x₀` explicit there, since there is no longer a hypothesis to infer it from). Drop the stale "It is possible that the hypothesis x₀ ∈ X is unnecessary" comment. `ContinuousWithinAt.comp` had `(hx₀: x ∈ X)` where `x` was an auto-bound implicit (not `x₀`), so the hypothesis was a latent typo. Remove it and make `x₀` explicit. Update cascaded call sites in 9.5, 9.6, 9.7, 9.9, 10.4, 11.9. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
