Patchwise Global Certification¶
Promote local checks to a global verdict only when the cover, witnesses, seam compatibility, and aggregation discipline are explicit.
Disposition¶
local_to_global_aggregation is processed as draft_full_archetype.
Pre-draft disposition check¶
Disposition check found no accepted archetype, pilot accepted gap-fill archetype, pilot variant addition, prior uploaded-queue output, alias-map entry, duplicate/merge-map entry, component, or mechanism that directly covers local_to_global_aggregation as the general pattern of certifying a whole from local witnesses under an explicit aggregation, overlap, or gluing discipline. The nearest accepted archetypes are bottom_up_signal_integration, which integrates local knowledge for decision-making; cross_scale_causal_mapping, which maps causal movement across micro, meso, and macro scales and includes a Local-to-Global Risk Map mechanism; nested_feedback_alignment, which aligns feedback loops across levels; compositional_assembly, which assembles components into a coherent whole; closure_preserving_operation, which keeps operation outputs inside a target domain; and completeness_audit, which searches for missing cases. These are neighbors or domain-specific instances rather than the general local-witness-to-global-verdict intervention. Prior queue outputs such as formal_derivation_system_design, composable_relation_modeling, complement_space_mapping, overlap_exclusion_design, reversible_operation_structure_design, shared_subset_intersection_mapping, and independent_contribution_set_design provide adjacent algebraic/set-theoretic structures, but none supplies the explicit local cover, local witness, compatibility-on-overlaps, obstruction handling, and global certification pattern. A distinct full archetype is warranted.
When This Archetype Applies¶
Partial catalog groundingSome structural conditions are represented by existing abstractions, but no sufficient condition set is fully represented.
Diagnostic problem
A system wants to make a whole-system claim without inspecting or proving the whole monolithically, but local checks can be incomplete, incompatible, biased by the cover, or invalid under the intended aggregation rule.
Applicability expression4 distinct conditions

4 conditions, all required.
4Required in every casenumbered 1–4
These hold no matter which pattern applies.
Monolithic evaluation infeasible · open
The whole is too large or costly to evaluate monolithically.
The source archetype describes the situation as follows: The whole is too large, distributed, complex, continuous, regulated, or costly to evaluate as one undivided object. The normalized requirement above isolates the load-bearing portion used in this condition set.
Composable local checks · grounded
Bounded local checks are meaningful and can be composed toward a global assessment.
The source archetype describes the situation as follows: Local checks, tests, witnesses, proofs, measurements, or inspections are tractable and meaningful within bounded patches. The normalized requirement above isolates the load-bearing portion used in this condition set.
primeLocal-to-Global Aggregation— Locally checkable properties promote to a global verdict under an explicit aggregation discipline.
Invisible boundary failures · grounded
Patch boundaries or overlaps may contain failures invisible to every isolated check.
The source archetype describes the situation as follows: Patch boundaries, overlaps, interfaces, levels, or handoffs may create failures that no single local check sees. The normalized requirement above isolates the load-bearing portion used in this condition set.
domainMerge Conflict— Halt an automatic merge and hand the decision to a human exactly where two branches diverged from their common ancestor on the same region, because a three-way merge over text can rank a one-sided edit but has no syntactic basis to choose between two competing edits whose correctness lives in intent it cannot see.

Nontrivial global composition · open
The global aggregation requires coverage, compatibility, order, weighting, induction, consensus, or gluing rather than bare summation.
The source archetype describes the situation as follows: The aggregation rule is not simple summation; it requires compatibility, coverage, ordering, weighting, induction, consensus, or gluing logic. The normalized requirement above isolates the load-bearing portion used in this condition set.
Other requirements and context (2)
Why these sit outside the expression
Goal — a goal states an intended outcome or evaluation criterion, not a pre-existing situation that independently summons the archetype.
Deployment constraint — it constrains how the intervention must be deployed, not the situation that calls for it.
GoalA global verdict is needed: certified safe, complete, valid, legal, covered, consistent, stable, acceptable, or ready.
Local evaluation makes global certification tractable, but local truth is not automatically global truth; the pattern must balance decomposition efficiency against seam risk, cover bias, aggregation error, and false confidence. In this archetype, the relevant goal is: A global verdict is needed: certified safe, complete, valid, legal, covered, consistent, stable, acceptable, or ready. It supplies a criterion for evaluating what the intervention should accomplish or preserve.
Deployment constraintAuditors, operators, or downstream users need to trace the global verdict back to local evidence and exceptions.

Drafting note¶
The target accepted prime appears in identity.source_primes. This draft deliberately names the archetype from the transferable solution action rather than simply using the prime name: certify a whole by validating local witnesses, checking coverage and seam compatibility, and applying an explicit aggregation discipline.
Common Mechanisms¶
8 documented mechanisms across 6 implementation forms.
The grouping reflects forms represented among the mechanisms currently documented for this archetype; an absent form is not necessarily an impossible implementation.
Assessment, Review & Assurance · 3 mechanisms
- Coverage Completeness Audit — Maps the union of the patches against the declared domain to prove no in-scope region is left unwitnessed, and logs every gap it finds.
- Local Witness Checklist — Defines what counts as valid evidence that the global property holds inside one patch, and records it the same way everywhere, so patch verdicts are comparable.
- Overlap Compatibility Test — Checks that local verdicts agree wherever patches meet, walking the seams in a fixed order, so the boundaries between patches cannot hide a global failure.
Control, Automation & Runtime · 1 mechanism
- Local-to-Global Dashboard — Keeps a live view of local-to-global status and fires revalidation the moment a patch changes underneath the standing verdict, so drift is caught rather than assumed away.
Decision, Gate & Allocation · 1 mechanism
- Obstruction Register Review — Collects every local failure, gap, and seam conflict into one register and adjudicates each — block, allow with a documented exception, or defer with a re-check trigger — before any verdict issues.
Protocol, Workflow & Routine · 1 mechanism
- Gluing or Recomposition Workflow — Fuses the passing local witnesses into one global verdict by applying the declared aggregation rule in a fixed composition order, only after the seams check out.
Record, Log & Register · 1 mechanism
- Patch Cover Inventory — Enumerates and justifies the set of local patches, and pins the domain they are meant to fill, so a whole can be certified piece by piece.
Representation, Specification & Plan · 1 mechanism
- Global Certificate Template — Issues a scoped certificate that states the global verdict and binds it to its cover, witness set, aggregation rule, and exceptions, traceable back to local evidence.
Compression statement¶
A design pattern for dividing a whole into local patches, validating each patch, checking overlaps and seams, recording obstructions, and issuing a scoped global certificate only when the declared local-to-global rule licenses the inference.
Canonical formula: Given cover {Uᵢ} of domain X and local witnesses wᵢ for property P on Uᵢ, infer P(X) only if coverage(X = ⋃Uᵢ), compatibility(wᵢ|overlap = wⱼ|overlap), and aggregation/gluing rule G({wᵢ}) are satisfied.
Related Abstractions¶

Editorial Notes¶
Problem Classification¶
Classification: Correctness, Conformance & Formal Validity Failure → Insufficient Conformance & Assurance Evidence
Problem kernel: local checks do not warrant a whole-system claim
Rationale: Earliest causal condition: A system wants to make a whole-system claim without inspecting or proving the whole monolithically, but local checks can be incomplete, incompatible, biased by the cover, or invalid under the intended aggregation rule.
Independent corroboration: The earliest necessary condition in the frozen evidence is: A system wants to make a whole-system claim without inspecting or proving the whole monolithically, but local checks can be incomplete, incompatible, biased by the cover, or invalid under the intended aggregation rule. That is a conformance assurance and certification problem because Outputs, controls, and whole-system claims are accepted without adequate evidence that enacted behavior meets requirements, tolerances, endpoint criteria, and valid evaluation conditions.
Review outcome: Independent reviewer agreement; high confidence.
