Both proofs unfold `IsFactor`, use `center_le_relativeCommutant` to embed the center into the relative commutant, apply irreducibility to collapse it to scalar operators, and then verify scalar multiples of the identity are indeed central.

Introduce `isIrreducibleInclusion_self_iff_isFactor` (stub, `sorry`) for the Minkowski and curved-spacetime Haag–Kastler nets, with matching blueprint theorems in both sections.

- Introduce `CStarCompletion A` as an abbreviation for `UniformSpace.Completion A` under the five C*-algebra hypotheses, matching the blueprint's standing-hypotheses definition. - Mark `def:completion-standing-hypotheses` with `\lean` and `\leanok` now that the Lean declaration exists.

- Split the `subset_causalConvexHull` and `isCausallyConvex_causalConvexHull` lean tags from the definition node to the lemma node where they actually live, eliminating three stale dependency edges. - Add `\leanok` markers to `lmm:causal-closure-is-closure-operator` and `lmm:causal-convex-hull-extensive` (statement and proof) to reflect their verified status. - Expand the prose in `lmm:causal-closure-is-closure-operator` to explain how Mathlib's `ClosureOperator` bundles the three closure-operator laws.

- Prove `mem_frontier_of_isMin`, `mem_frontier_of_isMax`, `isEndpoint_of_isPastEndpoint`, `isEndpoint_of_isFutureEndpoint`, and `parameterSpace_eq_Icc_of_endpoints` in Lean. - Annotate the corresponding blueprint lemmas with `\lean`, `\leanok` tags to reflect their proved status.

- Split the old monolithic `def:quasilocal-completeness` into three nodes: the interpretive bridge principle (Axiom 4), a standalone `thrm:quasilocal-algebra-exists` theorem with a full diagnosis of why the existing Lean declaration is refutable, and `thrm:quasilocal-strongly-dense` explaining why the bicommutant excess doesn't falsify the axiom. - Decompose the quasilocal-algebra existence proof into five named supporting lemmas (`lmm:quasilocal-embedding`, `lmm:quasilocal-embedding-injective`, `lmm:quasilocal-embedding-cocone`, `lmm:quasilocal-colimit-union-of-insertions`, `lmm:quasilocal-embeddings-dense`) and add `lmm:completion-coe-star-alg-hom` for the bundled coercion map. - Update downstream `\uses` references in purity theorems to point at `def:quasilocal-algebra` and `thrm:quasilocal-algebra-exists` instead of `def:quasilocal-completeness`.

Change the `ι` field of `QuasilocalAlgebra` from a total family indexed by all subsets to one indexed by `IsAlexandrovBasisSet` proofs. All downstream sites (`LocalCommutativity`, `LocalVonNeumann`, `GeometricCovariance`, `EinsteinCausality`, `Net`, `QuasilocalIntertwiner`, `QuasilocalAction`) are updated to pass the basis-set hypothesis explicitly. The blueprint comment on `def:quasilocal-algebra` explains why a total `ι` makes the structure uninhabitable when local algebras on non-basis sets are nontrivial.

- Introduce `universe u` in Net, QuasilocalAlgebra, QuasilocalCompleteness, QuasilocalIntertwiner, EinsteinCausality, Purity, and VacuumState to propagate universe polymorphism throughout the AQFT hierarchy.
- Change `QuasilocalAlgebra.carrier` from `Type` to `Type u` and `HaagKastlerNet.U` from `LocalNet` to `LocalNet.{u}`, eliminating the uninhabitability defect that arose when local algebras live in a universe above `0`.
- Replace bare `Type` with `Type u` in all GNS existential statements and `Type*` in Hilbert-space section variables; pin nonemptiness witnesses to universe `0` with explanatory comments.

- Mark lemmas (ii) and (iii) as fully formalized and remove the stale caveat that they were open.
- Replace the two-bullet diagnosis of false Lean claims with a four-part retrospective: what was wrong (over-broad ι, pinned carrier, pinned net universe), what was done (restrict ι to basis sets, tie carrier to LocalNet.{u}, lift HaagKastlerNet and CovariantQuasilocalAlgebra), and why the theorem node stays untagged (embeddings and assembly still missing, not a false statement).
- Record that QuasilocalColimit and QuasilocalCompletion are now declared over LocalNet.{u} with result Type u, making the colimit-and-completion chain universe-polymorphic.

- Prove `colimitStarOf`, `quasilocalEmbedding`, `quasilocalEmbedding_transitionHom`, `exists_eq_colimitStarOf`, `dense_iUnion_range_quasilocalEmbedding`, and `colimitStarOf_injective` in `QuasilocalColimit.lean`, covering blueprint nodes `lmm:quasilocal-embedding` through `lmm:quasilocal-embedding-injective`.
- Add `coeStarAlgHom` in `CStarCompletion.lean` bundling the completion coercion as a `StarAlgHom` (`lmm:completion-coe-star-alg-hom`).
- Assemble all five ingredients into `exists_quasilocalAlgebra` in new file `QuasilocalExistence.lean`, proving `thrm:quasilocal-algebra-exists`.
- Mark the corresponding blueprint nodes `\leanok` and add `\lean{…}` tags; remove the now-superseded obstacle comment from `QuasilocalColimit.lean`.

… 4 as a b… - Remove `QuasilocalCompleteness` as a `Prop`-valued field of `HaagKastlerNet`; the quasilocal algebra is now obtained via the theorem `exists_quasilocalAlgebra` rather than assumed. - Add `ObservableBridge.lean` encoding Axiom 4 as `ObservableCorrespondence`, an abstract structure pairing an uninterpreted `Observable` type with a self-adjoint-valued map into the quasilocal algebra; prove `isQuasilocalObservable_measure` making the correspondence representation-independent. - Update blueprint prose and `\uses` annotations for `def:haag-kastler-net` and `def:quasilocal-completeness` to reflect that Axiom 4 is a bridge principle with no mathematical consumers and that `thrm:quasilocal-algebra-exists` is now fully formalized.
