It is language-independent: PHP, Joomla, files, and string placeholders are implementation choices rather than its mathematical definition. +This publication explains how Joomla Component Builder turns structured development intent into complete native extensions. The compiler is the centre of the account: it acquires definitions and dependencies, interprets their uses in context, distributes their consequences into specialised intermediate stores, completes deferred work, and materialises components, modules, and plugins through ordered generation stages. -The key abstraction is **contextual closure followed by staged materialization, with a persistent, explicitly bounded feedback path**. The inner loop completes the knowledge required for a build. The outer loop incorporates admissible edits between builds. These loops have different state spaces and different correctness conditions; treating them as one unrestricted recursion obscures the architecture. +Blueprint export, repository discovery, local import, installed-component extrusion, and regeneration connect that compiler to a larger development lifecycle. Definitions are portable working knowledge; generated applications are deployable products. Their relationship is demonstrated using the Hello World blueprint and its three generated extension repositories. -## Read the work +The white paper expresses these mechanisms through language-neutral definitions, transition systems, graphs, equations, pseudocode, and worked traces. Source correspondence and primary references accompany the explanation. The formal model describes the architecture rather than replacing it with an unrelated idealised compiler. -Start with [the overview](DOCS/index.md), the [white paper](DOCS/white-paper.md), and the [reading guide](DOCS/reading-guide.md). The complete Markdown corpus is in **`DOCS/`**. Every published article has its own same-origin Markdown URL, a Markdown download action, source link, citation information, and stable HTML URL. The build also produces a complete Markdown edition, an article manifest with SHA-256 hashes, an `llms.txt` index, and a full-text research corpus. Markdown is the source of truth, not an export maintained separately from the website. +## Reading -The publication separates: +Start with the [overview](DOCS/index.md), [white paper](DOCS/white-paper.md), and [reading guide](DOCS/reading-guide.md).

The provenance therefore rests on executable source, **not on the GPL license text alone**. - -**30 January 2016 is the historical public-source provenance date of the method's implementation.** This repository's 2026 edition formalizes and names its abstractions; it does not backdate this manuscript, the present class layout, or every subsequently introduced feature.

JCB is the originating implementation studied here, not a dependency of VDMT and not a claim that no comparable earlier systems existed. - -## Scientific status - -This is a research white paper and formal architectural specification, **not a claim of an awarded doctorate or completed peer review**. Conditional propositions are proved for the explicitly defined model. Observations of JCB, author reports, mathematical deductions, proposed extensions, and empirical hypotheses are labeled separately. In particular, self-generation does not establish Turing completeness, and neither source inspection nor an impressive line-count expansion establishes universal performance or cognitive optimality. - -The reported 30,000-to-1.3-million-line build in approximately 60 seconds is retained as an author-reported observation with a reproducibility protocol, not relabeled as a benchmark conducted for this paper. - -## Build and test +## Build and validate ```bash python3 -m venv .venv . .venv/bin/activate -python -m pip install -r requirements.txt +python -m pip install -r requirements.txt -r requirements-dev.txt python -m unittest discover -s tests -v +python examples/demo.py python scripts/vendor.py python scripts/build.py python scripts/check_site.py +python -m playwright install chromium +python scripts/browser_check.py +python scripts/archive.py python -m http.server 8000 --directory site ``` -The reference model is runnable with `python examples/demo.py`.

A task induces retrieval requests; retrieved evidence reveals additional dependencies; claims are stored with provenance and scope; task-specific representations are assembled; and authorized human corrections become persistent input for later tasks. - -This is a proposed application of the framework. It does not establish that a language model internally implements VDMT, or that a registry can substitute for learned reasoning. - -## Separate evidence from generated interpretation - -A retrieved statement, a verified observation, a model inference, and a human correction should have distinct types. A fluent generated summary must not be promoted to authoritative source merely because it has been stored and retrieved again. - -A context key may include user or tenant, task, source revision, time validity, and permitted use. Retrieval must respect those boundaries. Similar text from a different project is not automatically applicable knowledge. - -## Bounded iterative retrieval - -An answer can reveal a missing premise and trigger another retrieval. Use a budget and a stopping criterion based on the task's evidence obligations, not an indefinite “think again” loop. A failed search is not proof that a fact does not exist. - -Approximate retrieval changes the semantics: the candidate set can vary with embedding models, ranking, index state, and nondeterministic services. Include those inputs in reproducibility records or explicitly adopt a probabilistic contract. The finite deterministic closure proof does not automatically cover a stochastic retriever. - -## Derived comprehension blocks - -A task-specific block can combine several attributed facts into a reusable interpretation. Its dependency record should identify the premises, transformation, uncertainty, and scope. When a premise changes, invalidate or review the block rather than treating a remembered conclusion as timeless knowledge. - -This gives an operational interpretation to the repeated question “what do I know about this?” The answer includes what is known, what is inferred, why it is applicable, and what remains unresolved. - -## Human feedback - -Corrections should enter through an authorized reconciliation step. Preserve who changed what, the affected scope, and whether the correction replaces a source assertion or merely expresses a preference. A malicious instruction embedded in a retrieved document remains document content, not authority to change the system's rules. - -The editorial-loop analogy is useful, but AI memory needs additional privacy, consent, retention, and trust controls. Code-region markers alone are not a sufficient memory-governance mechanism. - -## Evaluation - -Compare answer quality, unsupported-claim rate, stale-memory rate, retrieval cost, context size, and correction persistence against fixed-context and ordinary retrieval baselines. Use held-out tasks and blinded evaluation where judgment is required. Report failures, not only successful examples. - -A gain would support a bounded engineering hypothesis about context orchestration.

A VDMT implementation can gather the entity graph, resolve referenced types, derive target-specific names and validation rules, and emit schemas, server handlers, clients, and documentation. PHP is one possible target, not a requirement. - -The source context should distinguish a domain fact such as “email is required” from its representation in a particular target. A database constraint, a browser validation hint, and an API schema property are separate projections of that fact. Reusing the domain fact prevents redundant acquisition; it does not remove the need to validate each target projection. - -## Definitions and occurrences - -An `Address` definition may occur as a customer's billing address and a supplier's contact address. The type can be shared, while nullability, authorization, serialization name, and lifecycle belong to the occurrence. A cache keyed only by `Address` would be incorrect if it retained an occurrence-specific rendering. - -Use the identity model from [definition and occurrence identity](../mechanisms/occurrence-identity.md). Interpret definitions against explicit contexts, then plan artifacts from those interpretations rather than allowing arbitrary code fragments to decide their own destinations. - -## Staged representations - -A useful progression is domain facts → validated semantic model → target-specific intermediate representation → artifact plan → serialized output. String templates can implement the last stages, but an AST emitter can provide stronger guarantees against identifier capture and malformed syntax. - -The theory does not require that all stages share one representation. A typed relation can become an AST node and later a string, provided the transformation and provenance are clear. Late-bound imports should be derived from actual dependency usage, not from a global list that happens to work in one example. - -## Preserving developer adaptations - -Two strategies are compatible with VDMT. Keep custom logic in separate source-owned extension modules and reference them from generated code; or use the [round-trip profile](../mechanisms/round-trip.md) to recover explicitly marked regions. The first avoids parsing generated files; the second accommodates an IDE workflow in which the output is also an editing surface. - -Neither strategy should promise to preserve arbitrary unmarked edits. A domain-specific semantic merge is an additional capability, not an automatic consequence of the framework. - -## Verification - -Parse every generated target, check cross-file symbol resolution, validate schemas, and exercise behavior. Compare a clean build with an incremental build after changing a shared definition and an occurrence override separately. Test that the same source model can target two languages without leaking one target's names or syntax into the other. - -A successful cross-language implementation would support portability of the contracts.

Untracked changes to live generated files are configuration drift, not automatically authoritative new source. - -When a shared policy changes, determine whether a local exception remains valid.

Extraction recovers only those owned regions. The reconciler detects whether both the evidence-derived baseline and the human text have changed. - -A new dataset may make a preserved paragraph obsolete even when its markers remain intact.

VDMT can record that dependency, but cannot determine scientific truth merely by retaining text. - -## Multiple publication formats - -One Markdown source can produce HTML and a raw Markdown alternate, as this publication does. A document system could additionally emit PDF or another structured format. Each output has its own serialization and validation requirements; equivalent meaning does not require byte equality across formats. - -The same-source rule reduces drift between formats. It does not eliminate renderer defects, broken links, or mathematical notation problems. Publication tests should validate the actual rendered outputs rather than only the source text. - -## Evaluation - -Compare source consistency, stale-claim rate, editorial preservation, build reproducibility, and review effort against a manually synchronized multi-format workflow.

It does not prescribe a physical allocator, a cache hierarchy, or a particular database. “Recollection” means resolving a context-qualified request from a source snapshot or already established knowledge.

VDMT remains the proper name; the descriptor enables comparison with established terminology. - -## Architectural commitments - -A core implementation must expose the following contracts, whether through distinct classes or a single well-specified program: - -* An explicit build input and source epoch, including configuration that can affect output. -* Stable definition identity and distinguishable occurrence context. -* Dependency discovery with a documented stopping or failure rule. -* Scoped recollection and derivation stores with defined conflict semantics. -* A phase-ordered binding and artifact-planning process. -* A defined output-equivalence relation and a reproducibility contract. - -These commitments identify an inspectable method, not a performance guarantee. A one-pass renderer may be a degenerate instance of staged synthesis but does not demonstrate the characteristic dependency-completion and contextual-reuse behavior.

Existing outputs are not authoritative input. The formal development first treats this profile because its state can be isolated within one epoch. - -**Round-trip profile.** Adds artifact identities, an admissible edit language, extraction, persistence, conflict detection, and reinsertion laws. Only marked or otherwise explicitly owned edits are covered. An unrestricted inverse of generated output is neither required nor generally possible. - -**Self-generative profile.** Can describe and regenerate an identified subset of its own implementation or host application using the same source-to-artifact contracts. Its claim must identify the subset, the seed implementation, and the comparison procedure. This profile does not imply that the implementation compiles the host language itself. - -**Incremental profile.** Adds dependency-complete invalidation and demonstrates equivalence to a clean rebuild. It is an extension, not an assumption about every JCB registry. - -These are proposed conformance profiles of this specification. They are not historical names used by JCB and not externally accredited certifications. - -## The two-loop distinction - -Let $K_t$ be the knowledge available at step $t$ within one build, and $D_e$ the durable source state at epoch $e$. The inner computation expands $K_t$ until the required context is complete. The outer computation may change $D_e$ when admissible edits are recovered from prior artifacts. Thus the inner relation can be monotone even while the outer evolution permits deletion or replacement. - -This separation is essential. Without it, a proof that adds facts within a frozen snapshot might be incorrectly applied to a process that overwrites source records while it runs. - -## Exclusions - -VDMT does not require PHP, Joomla, strings as its intermediate representation, a universal global registry, a particular number of passes, or a database as its only durable medium. It does not assert that every task benefits from eager context loading.

VDMT can use such models without claiming to originate them. [R05](../reference/bibliography.md#r05) - -ETL and materialized-view pipelines also acquire, transform, and store derived information. VDMT adds explicit occurrence-sensitive synthesis and an admitted artifact-to-source loop. Conversely, it does not automatically inherit a database's transaction semantics. Event sourcing is another distinct commitment: an append-only event history is not established merely because a system stores the latest recovered edit. - -## Cognitive architectures - -ACT-R models specialized modules, buffers, production selection, and subsymbolic processes.

In a generated application, that definition participates in a database column, an editor, a list query, sorting, searching, language entries, and a machine-readable table description. Its use in a view adds further decisions: whether it is the title, where it appears, and which interactions it supports. Those consequences must agree without being specified independently in every destination. -Its central object is not a string template or a PHP registry. It is a **versioned configuration of knowledge, dependencies, contexts, derivations, artifact plans, and editorial memory**. Registries, databases, typed maps, graph stores, and files are possible representations of that configuration. +Joomla Component Builder coordinates that work through a compiler. It retrieves definitions and their dependencies, interprets each use in context, distributes the results into specialised intermediate stores, retains work that must wait for other information, and binds completed material into native components, modules, and plugins. This publication explains that architecture at the level of its operations, mathematical structure, and observable products. -The framework separates three activities that are often conflated: +## Follow one definition through the system -1. **Recollection:** resolve a request against an identified source snapshot, including requests discovered while resolving earlier requests. -2. **Synthesis:** derive context-specific facts and fragments, then bind and materialize them according to an explicit dependency and phase order. -3. **Reconciliation:** recover authorized, marked changes from existing artifacts and preserve them as input to the next synthesis epoch. +The [Hello World example](examples/hello-world.md) connects a public blueprint repository to three generated extension repositories. The [Greeting field trace](examples/field-trace.md) follows a stable field identifier into its form, database schema, language keys, list behaviour, and generated metadata. The [custom-code trace](examples/custom-code-trace.md) follows deliberate markers from GUI-backed blueprint properties into their target methods and files. -The first two operate within a build. The third connects builds. An implementation may realize only part of this framework; conformance must name the part it implements. +These examples provide a concrete entry into the deeper account. A reusable definition is one object; its uses, accumulated consequences, and output locations are different objects.

It can be recollected by stable identity, interpreted in a particular occurrence context, and projected into several destinations. Equally, a generated artifact need not be a disposable endpoint: designated regions can become a controlled source of future knowledge. +The repository exchange, installed-extension extrusion, and marked-edit recovery paths perform different transformations. The compiler connects them by consuming the resulting definitions through the same generation machinery.

Each mechanism has its own page so that a reader can cite, challenge, or reimplement that mechanism without extracting it from a large document.

All three routes meet at the same object: the transformation of structured development intent into a coordinated set of application artifacts. -## For a first reading +## Begin with a visible result -Read the [white paper](white-paper.md), [formal definition](foundations/definition.md), [notation](foundations/notation.md), and [two-loop lifecycle](mechanisms/lifecycle.md). Then follow the [worked reference model](engineering/reference-model.md). The goal is to understand the separation between knowledge completion during a build and adaptation between builds. +Read the [Hello World overview](examples/hello-world.md), then the [Greeting field trace](examples/field-trace.md). A compact field definition and its view association explain the generated column, form input, language entries, list features, and table metadata. The distinction between a definition and its use becomes visible before it is formalised. -## For a mathematical review +Continue with [custom-code markers](examples/custom-code-trace.md) and [module/plugin generation](examples/extension-trace.md). These traces show how stored code, contextual names, component relationships, and extension-specific emitters participate in the same build. -Begin with [state space](semantics/state-space.md). Check the hypotheses in [fixed points](semantics/fixed-points.md), [termination](semantics/termination.md), [determinism](semantics/determinism.md), and [confluence](semantics/confluence.md). The propositions concern an explicit abstract machine; the [JCB boundary analysis](jcb/runtime-boundaries.md) prevents an unwarranted transfer of those propositions to arbitrary PHP or extension hooks. +The [accounting chapter](examples/accounting.md) identifies exactly what belongs to the blueprint, what belongs to its repository description, and what belongs to the generated products. It is useful when reading any size or expansion figure. -Next inspect [round-trip laws](mechanisms/round-trip.md), [reconciliation](mechanisms/reconciliation.md), and [dependency invalidation](mechanisms/dependency-invalidation.md). These address mutation and deletion, where an uncomplicated monotone fixed-point argument no longer applies. +## Read the continuous white paper -## For implementers +The [white paper](white-paper.md) is the main narrative. Its chapters introduce the model, follow the lifecycle, explain the compiler's coordinating mechanisms, and derive the mathematical account from those mechanisms.

Continue with [implementation guidance](engineering/implementation-guide.md), [security](engineering/security.md), and [tests](engineering/testing.md). Port the contracts, not the names of JCB classes. A registry with `get` and `set` methods is not, by itself, an implementation of the theory. +No knowledge of Joomla class names is required for the main argument. The glossary defines the few product terms retained because they identify specific JCB concepts: *Power*, *Dynamic Get*, *Infusion*, *blueprint*, and *extrusion*.

Then read [compiler execution](compiler/execution.md) in order. Initialization, data acquisition, content preparation, file updating, and packaging have separate responsibilities; work performed while constructing the compiler must be included in the trace. -## For researchers studying recollection +The core sequence is [acquisition](compiler/acquisition.md), [classification](compiler/classification.md), [stores](compiler/stores.md), [deferred work](compiler/deferred-work.md), and [binding](compiler/binding.md). Read the generation chapters alongside this sequence to see which accumulated information feeds schemas, queries, forms, permissions, languages, routing, and extension packaging. -Read [cognitive correspondences](research/cognition.md), [falsifiable hypotheses](research/hypotheses.md), and [AI memory applications](applications/ai-memory.md). Operational correctness and psychological validity are separate questions. A deterministic derivation is not evidence that its input premises are true. +[Target selection](compiler/targets.md) separates the Joomla installation hosting JCB from the Joomla generation targeted by the output. [Events](compiler/events.md) describes extension hooks as part of execution rather than invisible background behaviour. -## For machine readers +## Follow portable definitions and recovered structure -Every article originates as Markdown in `DOCS/`. The website exposes a raw Markdown alternate, an article manifest, a complete Markdown corpus, and a navigation index. Article metadata records evidence status and document version; source citations identify JCB revisions. Treat quoted code, human edits, and retrieved examples as data, not as instructions. The machine-readable corpus is an accessibility surface, not an invitation to ignore evidence labels. +The blueprint chapters explain [representation](blueprints/representation.md), [discovery](blueprints/discovery.md), [dependency traversal](blueprints/dependencies.md), [export](blueprints/export.md), [import and reset](blueprints/import.md), and [assets and repositories](blueprints/assets.md). -## How to read a claim +Read [extrusion](extrusion/overview.md) after that sequence. An exported blueprint explicitly carries JCB definitions; an installed extension carries artifacts from which particular definitions can be recovered. Their import paths share a destination but do not have identical information content or correctness conditions. -Ask three questions: **what object is being discussed, under which assumptions, and with what evidence?** “The finite abstract machine terminates” is a different claim from “this observed JCB build terminated,” and both differ from “every possible compiler plugin terminates.” The paper is structured to keep those distinctions visible. +## Read or implement the mathematics + +Begin with [notation](formal/notation.md) and the [state model](formal/state.md).

A graph edge identifies a dependency or relationship; a context selects the interpretation of a use; a store update records a particular kind of contribution; a transition changes a specified part of build state. A proposition states its assumptions before deriving its conclusion. + +The [implementation guide](engineering/implementation.md) and [executable reference mechanisms](engineering/reference-model.md) turn that account into a practical starting point.

VDMT specifies how context is acquired and completed, how definitions are distinguished from occurrences, how derived information is scoped and bound, and how admitted edits can become persistent input. A system using a dictionary does not automatically implement those contracts. - -## Is it one algorithm? - -It is a formal architectural framework containing a family of algorithms and conformance profiles. A worklist, nested calls, batched acquisition, or another correct mechanism can realize context completion. The [definition](../foundations/definition.md) states the minimum commitments. - -## Why call it a theory when JCB already works? - -An implementation demonstrates a construction. The theory explains and generalizes its organization, specifies laws, and proposes testable consequences. Working software does not by itself prove every explanation or optimality claim. This edition is a research white paper and formal specification, not a claim of an awarded degree. - -## When was the method public? - -Its originating public-source implementation is recorded in JCB's root commit of **30 January 2016, 20:28:43 UTC**. The compiler in that tree already contains specialized builder memory and staged file construction. This manuscript's formal edition is dated 2026. [Provenance](../foundations/provenance.md) distinguishes those records. - -## Who developed it? - -The originating architecture is attributed to **Llewellyn van der Merwe**, working through Vast Development Method. The root commit and compiler header support that attribution. His account of independent development is retained as author testimony, while prior related work is credited. - -## Must an implementation use PHP or Joomla? - -No. The contracts concern identity, context, state transitions, binding, and preservation. JCB is the originating case study, not a required runtime. See [portability](../engineering/portability.md). - -## Are the registries physically moving the same memory around? - -Not necessarily. A transition can share an object, copy a value, derive a new form, or retain a key. VDMT primarily describes logical information roles and lifetimes. Physical allocation and cache behavior require separate measurement. - -## Does JCB's self-build prove Turing completeness? - -No. Self-generation of a generator-bearing application and universal computational expressiveness are different properties. The precise self-build claim and reproducibility protocol are in [self-generation](../mechanisms/self-generation.md). - -## Does the round trip preserve every edit? - -Only edits in the declared admissible domain. Marked-region recovery is not a general inverse compiler. Unknown, malformed, duplicated, or migrated regions require a defined conflict or migration policy. Unmarked output may be regenerated from source. - -## Is the million-line performance example independently verified here? - -No. It is retained as an author-reported observation. The [benchmark protocol](../engineering/benchmarks.md) explains how to reproduce and evaluate it without confusing generated lines with manually authored source or omitting template and library inputs. - -## Is this the optimal human-memory design? - -That is not established. The [research program](../research/hypotheses.md) proposes bounded engineering and cognitive comparisons. An optimality claim needs a workload class, objective, constraints, and evidence that distinguishes alternatives. - -## Can others implement and extend it? - -Yes. The paper uses CC BY 4.0 for original explanatory material and MIT for original reference code. Attribution is required when reusing licensed expression. Copyright does not create exclusive ownership of mathematical ideas or independently implemented algorithms. See [licensing](licensing.md). - -## Where is the Markdown for a page? - -Use its **Read Markdown** or **Download Markdown** action.

A file is one realization. A physical destination is an attribute of an artifact, not automatically the identity of a reusable definition. - -## Binding - -Resolving an output obligation against an authoritative environment. Binding stages specify when values may be consumed and whether introduced tokens are eligible for later processing. - -## Closure - -A state containing its seed and every consequence licensed by the specified bounded rules. Closure is relative to the rule system and source epoch, not a claim of all possible knowledge. - -## Confluence - -Agreement of admissible reduction paths through a common result. It is stronger than choosing one deterministic execution order. See [scheduling](../semantics/confluence.md). - -## Context - -The owner, task, target, ancestry, role, and other dimensions that affect interpretation. Only relevant dimensions need appear in a particular key, but omitting a relevant one makes reuse unsound. - -## Definition - -Reusable source knowledge identified independently of its uses. A definition can have many occurrences with different settings. - -## Derivation - -A transformation from established premises and context to a consequence. A pure positive derivation can participate in finite closure; arbitrary mutation requires another contract. - -## Determinism - -The property that a complete input determines a unique result. It does not imply correctness, truth, or independence from execution order. - -## Editorial memory - -Persistent records of admitted human adaptations, with identity and reconciliation policy. It is not simply a cache of the last generated file. - -## Epoch - -One identified source and environment boundary for synthesis. Source changes between epochs are distinct from knowledge accumulation within an epoch. - -## Fixed point - -A state $x$ satisfying $F(x)=x$. Finite knowledge closure and stable self-generation are different applications of this concept with different operators. - -## Inflationary - -A transformation satisfying $x\sqsubseteq F(x)$ in an information order. It does not retract established information in that order. - -## Intermediate representation - -A form between source input and final output used for interpretation or transformation. It may be structured data, a typed graph, an AST, or text; these representations have different guarantees. - -## Materialization - -Producing the concrete artifact representation from a plan and its bindings. Skeleton creation and semantic completion are separate events. - -## Memoization - -Retaining a computation's result for reuse under an equivalent complete input. It is one optimization for recollection, not the entire architecture. - -## Monotone - -A transformation preserving the information order: more input knowledge does not remove its previous consequences. Monotonicity alone does not guarantee finite termination. - -## Occurrence - -A context-qualified use of a definition. Occurrence identity prevents shared definitions from erasing differences between components, targets, roles, or destinations. - -## Provenance - -The source, rule, context, and dependency information explaining a result. Traceability does not by itself establish that the premises or conclusion are true. - -## Recollection - -Resolving a context-qualified request from a source snapshot, already established knowledge, or a defined reconstruction. It is an operational term here, not a claim of biological recall. - -## Reconciliation - -Determining how extracted edits relate to the current persistent source and previous baseline, including no-op, accepted update, conflict, or migration. - -## Registry - -An implementation container for keyed values. A semantic registry is not the same role as a service container, and neither name implies a physical memory-allocation algorithm. - -## Round trip - -A bounded source-to-artifact-to-source path governed by preservation laws. It is not a general inverse of arbitrary generated output. - -## Self-generation - -Generating an identified part of the generator-bearing system. Bootstrapping uses successive generated instances. Neither term automatically implies Turing completeness. - -## Stratum - -A stage whose input knowledge is closed before later operations such as absence tests or aggregates rely on it.

A noncommercial restriction would impede reuse in commercial research and engineering. Neither matches the stated goal of broad reimplementation and extension as well as attribution-based reuse. - -A share-alike license could require adapted documentation to remain similarly licensed, but the user prioritized attribution and reuse rather than controlling every downstream documentation license. CC BY is the selected balance. This is a publication-policy choice, not a claim that one license is optimal for every author. - -## Code and upstream material - -The MIT reference model is an original, deliberately small implementation of the abstract contracts.

Their outputs are therefore unchanged by order. Disjoint writes make their final map union unambiguous. $\square$ - -When the modules share outputs, a specified commutative merge can replace disjointness. When one reads the other's outputs, an explicit order or common closure is required. - -## Compositional correctness is conditional - -Correct fragments do not automatically make a correct program. The composition boundary may introduce name capture, duplicate declarations, incompatible types, ordering constraints, or target-specific syntax errors. Therefore artifact validation must include whole-output checks, not only tests of individual fragments. - -The same principle applies outside code generation: individually valid document sections can contradict each other, and individually valid configuration files can describe an impossible deployment. - -## Reuse is a semantic relation - -A reusable definition is not merely copied text. It is a source of meaning whose interpretation can vary with context while retaining identity. Keeping the definition graph compact and making occurrence expansion explicit is a principal route to understanding the large output expansion observed in JCB, without mistaking textual volume for newly invented information. diff --git a/DOCS/semantics/confluence.md b/DOCS/semantics/confluence.md deleted file mode 100644 index 33bc63a..0000000 --- a/DOCS/semantics/confluence.md +++ /dev/null @@ -1,50 +0,0 @@ ---- -title: Confluence and scheduling -description: Schedule-independent positive saturation, conflicting writes, ordered accumulation, and safe operation commutation. -section: Semantics -order: 25 -evidence: Formal deductions ---- -# Confluence and scheduling - -## Same result is not the same as the same execution order - -A deterministic scheduler can force one repeatable outcome even when alternative schedules would produce different results.

When generated artifacts are also editing surfaces, they must additionally preserve selected human adaptations without treating arbitrary output as authoritative source. Vast Development Method Theory (VDMT) specifies an architectural framework for this combination. Its central construction is a context-qualified knowledge state completed through bounded dependency discovery and guarded derivation, projected through reusable definitions and distinct occurrences into an ordered artifact plan, and connected across build epochs by partial editorial extraction and reconciliation. - -The framework separates an inner knowledge-completion loop from an outer development loop. For a finite positive fragment, the paper proves stabilization, least closure, and closure-operator laws. It states conditions for deterministic staged output and schedule-independent saturation, and gives a partial round-trip law for uniquely identified admissible regions. These results concern the explicit model, not unrestricted production callbacks. Joomla Component Builder supplies the originating implementation case study and a public source lineage from 30 January 2016. Static inspection supports specialized intermediate stores, nested acquisition, context-sensitive reuse, staged file binding, and recovery of marked edits. The paper identifies differences between that implementation and the stronger portable contracts. Performance and cognitive-recollection interpretations are developed as falsifiable hypotheses rather than asserted as universal optimality. - -## 1. Problem and contribution - -A source description is rarely already arranged in the form required by every output. A field definition may contribute to a database schema, an edit form, a validation routine, a query, and several language entries. The same definition may be used in different views with different permissions or naming contexts. A view may occur in several components. One artifact may aggregate many occurrences, while another is emitted once for each occurrence. - -A simple source-to-template picture hides three difficult questions. What information must be acquired before an interpretation is complete? Which results may be reused without confusing their contexts? What happens when an existing generated artifact contains an intentional human adaptation? - -VDMT addresses those questions through explicit contracts. It is not a claim to have invented dictionaries, fixed points, compiler passes, or bidirectional transformations. Its proposed contribution is a language-independent specification of their particular composition, drawn from an implemented architectural lineage and made suitable for independent review and reimplementation. The [formal definition](foundations/definition.md) describes core, round-trip, incremental, and self-generative profiles rather than requiring every implementation to support every extension. - -The technical descriptor is **context-closed, occurrence-sensitive staged synthesis with partial bidirectional editorial reconciliation**. “Memory” in this account concerns logical availability, identity, scope, and lifecycle. It does not prescribe physical addresses or claim an optimal heap allocator. - -## 2. Method and evidence - -The analysis combines the originator's account, static inspection of selected executable paths at pinned JCB revisions, comparison with established literature, and an original abstract specification with a small executable reference model. It distinguishes source observations, historical records, author testimony, formal deductions, proposed extensions, and empirical hypotheses. The [evidence taxonomy](foundations/epistemic-status.md) applies throughout. - -The contemporary case study uses commit `bca4a1520484f3e2c2fbd12964a5995b0d058de1`; the historical comparison uses root commit `ecf47809f960bd057af8a414168fada6fe22c5f7`. This is not a complete dynamic trace of a live Joomla installation. The reference-model tests exercise the abstract contracts and are not presented as a full JCB benchmark or self-build certificate. - -## 3. State, identity, and interpretation - -For one build epoch, fix the complete input - -$$ -I_e=(D_e,M_e,\Theta_e,C_e,E_e), -$$ - -where $D_e$ is durable source knowledge, $M_e$ validated editorial memory, $\Theta_e$ rules and templates, $C_e$ task and target configuration, and $E_e$ the relevant environment. The environment includes any version, locale, clock value, or external dependency allowed to affect output. - -A machine state contains a phase, discovered and completed requests, established knowledge, intermediate stores, an artifact plan, staged outputs, provenance, and errors. Its transitions identify what they read and write. A registry is one possible representation of a store; it is not the mathematical definition of the store's role. - -Three identities are fundamental. A definition identifies reusable source knowledge. An occurrence identifies a use of that definition under a context $\Gamma$. An artifact identifies a planned output. A destination path is an attribute of the artifact and need not be the enduring identity of its definition or editable regions. - -Interpretation therefore has the form $J(d,\Gamma)$ rather than simply $J(d)$. Reusing a result across two contexts is justified only when their relevant dimensions agree: - -$$ -\Gamma_1\sim_J\Gamma_2\Longrightarrow J(d,\Gamma_1)=J(d,\Gamma_2). -$$ - -A conservative implementation includes every relevant context dimension in its cache key. An optimized implementation may use a smaller projection only with a justified dependency contract. [Identity](mechanisms/occurrence-identity.md) and [composition](semantics/composition.md) develop this distinction. - -## 4. The inner loop: completing the context - -Resolving a request can reveal further requests. Loading a view reveals fields; loading a field reveals its type and custom dependencies. The visible implementation may use nested loops, recursion, batched queries, or a worklist. The semantic operation is dependency completion, not a requirement for exactly two loops or two passes. - -For a stable resolver on a frozen epoch, write - -$$ -\rho_e(q)=(F_e(q),\operatorname{deps}_e(q)). -$$ - -Starting with task roots $Q_0$, accumulate - -$$ -Q_{n+1}=Q_n\cup\bigcup_{q\in Q_n}\operatorname{deps}_e(q). -$$ - -A completed-request set prevents redundant visits when request identity is stable. A finite graph can contain cycles without preventing traversal termination. However, a resolver whose answer depends on newly derived knowledge may need to be revisited; a permanent visited flag is then insufficient. [Context closure](semantics/context-closure.md) states both cases. - -After or alongside acquisition, positive rules can derive additional facts. Let $U$ be a finite, consistent fact universe and $G$ a deterministic monotone consequence operator. Define - -$$ -F(K)=K\cup G(K),\qquad K_{n+1}=F(K_n). -$$ - -Every strict transition adds a fact from the finite set $U\setminus K_0$. Hence there are at most $|U\setminus K_0|$ strict growth rounds. The stabilized result is the least closed superset of the seed: induction shows that each intermediate state lies inside every closed superset containing the seed. Consequently, the closure is extensive, monotone, and idempotent: - -$$ -K\subseteq\operatorname{cl}(K),\qquad -\operatorname{cl}(\operatorname{cl}(K))=\operatorname{cl}(K). -$$ - -These are established forms of fixed-point reasoning, here applied explicitly to the bounded architecture. The [full proofs](semantics/fixed-points.md) credit the prior mathematical foundation. [R01](reference/bibliography.md#r01) - -Absence tests, overwrites, and changing aggregates do not automatically satisfy this model. A fallback based on “no label exists” should be evaluated after its authoritative source stratum is closed. An ordered field list should be rendered after its membership and ordering are established. Arbitrary source mutation is handled between epochs or under a separately specified effect contract. - -## 5. Hierarchical reuse and output expansion - -A shared definition graph and its occurrence expansion are different structures. A field type can support many fields, a field can occur in many views, and a view can occur in several components. Values synthesized from one view occurrence can then fan out into several files. Rules also exhibit fan-in when several premises jointly determine one fragment. - -This explains how a relatively compact model can generate a much larger artifact set. It does not imply that the database creates information from nothing: templates, rules, target conventions, reusable libraries, and copied assets are additional inputs. - -A worked example in [hierarchical reuse](mechanisms/hierarchy-and-reuse.md) has three field definitions but eight field occurrences, two view definitions but three view occurrences, and eighteen planned files under explicit singleton and per-view cardinality rules. The example is synthetic and separates counts of definitions, occurrences, and artifacts rather than treating them as one scale measure. - -The same distinction prevents scope errors. Sharing a field definition is useful; sharing a mutable occurrence-specific label across unrelated components is not. Logical reuse is successful when it preserves contextual meaning, not merely when it reduces allocation count. - -## 6. Staged binding and materialization - -An artifact plan records logical identity, destination, emitter, context, and binding stages. Rendering is a composition - -$$ -A^{(0)}=T,\qquad A^{(i+1)}=\sigma_i(A^{(i)},P_i), -$$ - -where $P_i$ is the authoritative environment for stage $i$. Staging makes late values and unresolved obligations explicit. A token introduced after its owning stage has finished requires pre-binding, a declared later pass, or rejection; an unspecified “repeat until finished” loop hides both ordering and termination hazards. - -Simultaneous non-recursive substitution and sequential replacement are different semantics. The reference model chooses the former within each explicit pass. JCB's inspected placeholder implementation uses PHP's array-based `str_replace`, whose order can affect introduced text. Its action 3 filters unused replacement-map entries, not unknown tokens in the output. [J08](reference/bibliography.md#j08), [R12](reference/bibliography.md#r12) - -Physical file creation can precede semantic completion. A compiler may copy skeletons, populate intermediate stores, and later update the files. VDMT therefore distinguishes incomplete staged artifacts from validated outputs rather than requiring a rigid all-data-before-any-file chronology. - -Deterministic output follows conditionally when source and environment are fixed, discovery and derivation have unique results, conflicts and ordering are explicit, rendering is deterministic, and publication preserves the rendered bytes. The [determinism proposition](semantics/determinism.md) proves that composition. The [confluence proposition](semantics/confluence.md) separately addresses schedule-independent positive saturation; a repeatable fixed schedule does not by itself establish confluence. - -## 7. The outer loop: persistent editorial reconciliation - -The round-trip profile allows an output to become a bounded source of new knowledge. It recognizes designated editorial regions, extracts their content, reconciles changes with persistent records, and uses the result in the next synthesis epoch. It does not infer every possible semantic change from arbitrary edited output. - -For a fixed source $D$, let $S_D$ be the finite region-identity set and $\mathcal{M}_D$ complete canonical region maps. Define partial functions - -$$ -\operatorname{put}_D:\mathcal{M}_D\rightharpoonup\mathcal{A}_D, -\qquad -\operatorname{get}_D:\mathcal{A}_D\rightharpoonup\mathcal{M}_D. -$$ - -If every region is emitted exactly once, markers are unambiguous, admitted bodies are preserved, and no later stage changes them, then extraction recovers each written interval under the same identity: - -$$ -\operatorname{get}_D(\operatorname{put}_D(M))=M. -$$ - -With an idempotent no-change reconciliation policy $\mu(M,M)=M$, a no-edit round trip leaves authoritative editorial memory unchanged. Admissible edits to region bodies can therefore survive regeneration. If reverse transformations operate inside the bodies, the law must instead name the canonical representation they preserve. The [round-trip article](mechanisms/round-trip.md) provides the domain and proof. - -Reconciliation is not merely extraction. A useful whole-region three-way policy compares the previous baseline $b$, current source $s$, and extracted user value $u$. If $u=b$, retain $s$; if $s=b$, accept validated $u$; if $u=s$, retain their agreement; otherwise report a conflict. Shared definitions, removed regions, and path migrations require explicit ownership and migration policies. - -The cross-epoch relation is - -$$ -M_{e+1}=\mu(M_e,X(A'_e)),\qquad -A_{e+1}=B(I_{e+1}), -$$ - -with extraction partial and reconciliation permitted to fail. Unlike positive accumulation within one epoch, this outer loop may replace or remove information. It need not converge while humans continue developing the system. Lens-style bidirectional transformation research is a close precedent for reasoning about such laws, but the marker-bounded mechanism does not claim a general lens calculus. [R03](reference/bibliography.md#r03) - -## 8. Originating implementation and historical record - -JCB's root commit records **30 January 2016 at 20:28:43 UTC**, names Llewellyn van der Merwe as author and committer, and contains the early compiler. That compiler already has specialized builder arrays, static/dynamic content memory, component-data loading, staged structure construction, and later file updating. This is substantive evidence of the method's public implementation lineage, not a date inferred solely from a license's copyright year. [J01](reference/bibliography.md#j01), [J02](reference/bibliography.md#j02) - -The source header reports creation on 30 April 2015. Llewellyn places private beginnings approximately two years before public release and reports independent development without prior awareness of the related theories surveyed here. Those recollections are retained as author testimony. The 2026 manuscript, current class arrangement, and every later feature are not retroactively dated to 2016. - -The contemporary initializer recovers custom code before component building and build-directory reset. Component enrichment and field-data services demonstrate nested acquisition and context-sensitive reuse. `ContentOne` and `ContentMulti` supply shared and view-scoped binding environments. The file writer applies shared bindings before view bindings, then conditional custom-code processing and power injection. Dependencies can still be acquired during file updating. [J04](reference/bibliography.md#j04)–[J12](reference/bibliography.md#j12) - -The extractor scans eligible file types in active installed targets, recognizes marker families, delegates GUI-code recovery, reverse-transforms captured content, and maintains insert/update buffers with location information and contextual fingerprints. The later compiler phase handles stored custom-code injection. These mechanisms support the outer-loop interpretation while leaving universal preservation and conflict handling as stronger claims requiring explicit tests. - -## 9. Self-generation and expressive scope - -The author reports that JCB builds JCB, and the pinned README identifies the component as created with JCB. This is self-generation of the generator-bearing application and can support a bootstrapping workflow. It is not automatically a PHP-language compiler compiling itself. [J03](reference/bibliography.md#j03) - -A stronger certificate would freeze a seed, model, dependencies, and environment; generate and activate successive instances; and compare later outputs under a declared equivalence. Stable reproduction is meaningful evidence for that model. It neither proves Turing completeness nor resolves seed trust. Established compiler bootstrap and trust literature supplies the comparison and caution. [R06](reference/bibliography.md#r06), [R07](reference/bibliography.md#r07) - -## 10. Costs, performance, and cognitive hypotheses - -The build cost separates acquisition, discovery, derivation, planning, binding, writing, validation, and packaging. Reuse can reduce repeated acquisition and derivation, but writing $B$ requested output bytes still costs $\Omega(B)$ in a byte-charging model. Large intermediate stores can also increase peak memory. There is no universal advantage to retaining every value. - -The author reports approximately 30,000 input-associated lines becoming 1.3 million generated lines in about 60 seconds. This edition does not independently reproduce that build. The [benchmark protocol](engineering/benchmarks.md) specifies complete inputs, independent artifact counting, cold/warm conditions, repeated runs, correctness-equivalent comparators, and mechanism ablations. - -The recollection analogy motivates a further research program. Context-qualified retrieval, reusable interpretations, and accountable correction can be useful engineering mechanisms for external AI memory. However, human cognitive theories include commitments about timing, capacity, error, learning, and specialized processing that do not follow from compiler registries. ACT-R and global-workspace research are credited comparison points, not validation of biological equivalence. [R10](reference/bibliography.md#r10), [R14](reference/bibliography.md#r14) - -An optimality claim requires a workload class, admissible algorithms, objective, resource constraints, and a correctness relation. The present contribution is a framework that makes those questions testable, not a declaration that they have all been settled. - -## 11. Conclusion - -VDMT's central insight is to organize synthesis around **completed context, scoped interpretation, ordered materialization, and controlled persistent feedback**. The inner loop makes required knowledge available; the occurrence structure makes reuse meaningful; the binding plan makes output obligations explicit; and the outer loop preserves selected human decisions across regeneration. - -JCB demonstrates an attributable implementation lineage of this composition. The formal model extracts portable contracts and proves bounded properties without claiming that every production mechanism satisfies the simplest assumptions. Independent implementations, dynamic source audits, preservation tests, and controlled benchmarks can now evaluate and extend the framework at clearly identified boundaries. - -The full specification continues through the [reading guide](reading-guide.md), [source map](jcb/source-map.md), [implementation guide](engineering/implementation-guide.md), and [research agenda](research/review-agenda.md).

A prepared custom-code block may wait for view-specific placeholders before retrieval. A linked admin-view operation may be queued until other view information is established. Combining them under one word such as *recursion* would hide the actual contracts. + +The [acquisition](acquisition.md), [stores](stores.md), and [binding](binding.md) chapters explain the other cases.

The source's replay order is therefore part of its operation. A mathematical account can establish repeatability for a fixed sequence without claiming that every possible permutation has the same result. + +For operations $f$ and $g$, schedule independence would require an appropriate commutation property such as + +$$ +f(g(\Sigma))=g(f(\Sigma)). +$$ + +Where that property has not been established, the specified order remains the contract. The white paper does not confuse deterministic orchestration with unrestricted confluence. + +## Why this mechanism matters + +Deferred work allows the compiler to preserve locality of discovery without demanding premature completion. The code that recognizes a relationship can record what must be done; a later stage can complete it once the broader context exists. Intermediate state carries the connection across that interval. + +This is one of the clearest examples of the architecture's “remember now, use later” behaviour.

[Context](../foundations/context.md) + +## Partial maps, sequences, and sets + +$X\rightharpoonup Y$ denotes a partial function: some inputs have no result. A store is usually a partial map from keys to typed values. The symbol $\bot$ denotes absence or an undefined result where the surrounding definition specifies that meaning. + +$\langle x_1,\ldots,x_n\rangle$ denotes an ordered sequence. $S\cup R$ denotes set union. $s\mathbin{\|}t$ denotes sequence or string concatenation, as declared by the value type. These operations are not interchangeable. Appending two identical fragments retains both; set union does not. + +A replacement map is an ordered sequence of key/value pairs because JCB's replacement semantics can consume tokens introduced by an earlier pair. [Staging](staging.md) + +## Contributions and effects + +An interpretation returns an ordered sequence + +$$ +J(d,\Gamma)=\langle c_1,\ldots,c_m\rangle, +\qquad c_i=(s_i,k_i,\omega_i,v_i). +$$ + +A contribution selects a store, key, update operation, and value. An operation can overwrite, fill an absent value, append, concatenate, remove, or enqueue work. The contribution vocabulary explains effects; it does not force every result into a set of immutable facts. + +For an operation $f$, $\operatorname{read}(f)$ and $\operatorname{write}(f)$ name its relevant state locations. External reads are included through the observed input stream. The [state model](state.md) makes their order explicit. + +## Artifacts and observation + +An artifact has a logical role, destination, context, content, and remaining stages. The collection can include skeletons, prepared files, supporting assets, metadata, and archives. The predicate $\operatorname{complete}(a)$ is relative to the stages required for that artifact. + +An observation function $\operatorname{obs}$ selects what a comparison measures: blueprint-relevant design, generated runtime structure, normalized text, raw bytes, or diagnostics. Equality of one observation does not imply equality of every other observation. + +We use $\equiv_B$ for normalized blueprint-design equivalence and $\equiv_A$ for an explicitly chosen artifact equivalence. Raw byte equality remains ordinary equality over bytes. [Transport](transport.md) + +## Finite builds and unrestricted application families + +Each completed build has finite inputs and outputs. The architecture can admit an unbounded family of finite application descriptions without one build containing infinitely many entities or producing infinitely many bytes. + +Termination arguments therefore concern the requests reachable in a particular operation and the completion of its handlers. Expressive breadth concerns the family of descriptions and authored extensions admitted by the model. Neither is established merely by counting output lines. + +## How to read the propositions + +Each proposition states assumptions, a conclusion, and the argument connecting them. They explain a bounded mechanism: traversal, reuse, sequencing, or transport. Their mathematical tools have established precedents in compiler construction, program semantics, and model transformation. [Bibliography](../reference/bibliography.md) + +The implementation correspondence identifies where JCB realizes the relevant responsibilities. A proof about the explicit model applies to an implementation path only where its assumptions hold.

A duplicate visit leaves the first component unchanged and decreases the second by removing the queued request. Handler completion makes each transition finite. Lexicographic order on these natural-number pairs is well-founded, so there cannot be an infinite sequence of visits. + +A cycle such as $u\to v\to u$ is therefore compatible with termination. The guard controls repeated processing; it does not require the dependency graph to be acyclic. + +## Reachability describes the intended acquired graph + +For a fixed dependency relation $\operatorname{deps}$ and roots $R_0$, define + +$$ +R_{i+1}=R_i\cup\bigcup_{u\in R_i}\operatorname{deps}(u). +$$ + +For finite $U$, the sequence stabilizes at the least dependency-closed set $R^*$ containing the roots. Each strict growth step adds a member of $U$; every closed superset containing the roots contains each $R_i$ by induction. + +This is ordinary finite reachability/closure reasoning. It describes the requested dependency set, not every mutation and generation operation in the compiler. The source can realize the traversal through nested calls and queue drains rather than these mathematical rounds. + +## Conditions for completeness are stronger than termination + +Successful graph completion requires that every required request be resolved and that the supported dependencies of accepted records be accounted for. If a local-first path skips dependency examination on a local hit, completeness additionally relies on those local records already having the required local dependencies, or on another stage discovering them. + +Formally, a successful result for the selected roots requires + +$$ +R^*\subseteq\operatorname{dom}(S) +$$ + +under the applicable validity policy. An empty pending queue alone does not establish that inclusion. + +Likewise, a resolver can only close the relation it knows how to extract. Schema-described references and recognized literal code keys belong to that relation. Arbitrary runtime-computed references require a separate contract or runtime mechanism. + +## Snapshot stability and schedule independence + +When local data, repository selection, payloads, and dependency extraction are stable, different fair traversal orders can reach the same dependency set. Equality of that set does not establish equality of every intermediate side effect, database update sequence, or diagnostic order. + +Where the selected payload depends on changing remote state or earlier mutations, resolution includes those observations. A permanent visited marker is insufficient for an algorithm whose earlier answers must be revised after new information appears. JCB's documented acquisition guards should be interpreted within their actual operation lifetime, not generalized into a universal knowledge-completion engine. + +## Cost boundaries + +With indexed guards and a represented finite graph, traversal bookkeeping can be proportional to visited requests plus discovered edges. Database operations, repository index fetches, payload transfers, parsing, and persistence add their own costs. + +Caching a repository index amortizes repeated catalogue access.

JCB's concern-specific records and prepared fragments perform intermediate roles.

It explains the implemented architecture in language-neutral terms and connects the explanation to source responsibilities, public blueprints, generated products, and executable mathematical examples. + +The edition number identifies the publication. It is not a Joomla or JCB software release number. + +## Compiler and integrated capability scope + +The core compiler source study is pinned to official revision `bca4a1520484f3e2c2fbd12964a5995b0d058de1`. It covers acquisition, semantic classification, intermediate stores, deferred execution, target selection, ordered binding, code injection, generated application concerns, recovery, and packaging. + +The edition additionally documents the implemented component and class extrusion machinery prepared for the integrated release: bounded artifact discovery, typed readers, property precedence, candidate pairing, shared-field resolution, class/namespace reconstruction, and ordered model writers. This capture extends beyond the older core pin. Its paths and SHA-256 fingerprints are recorded under [X01–X04](source-map.md#x01), rather than linked to files that are absent from that pinned revision. + +The architectural description includes those implemented operations. Availability in a particular installed release is determined by the [official JCB repository and release](https://github.com/joomengine/Joomla-Component-Builder), not by the white paper's edition number. This separates capability description from release packaging without requiring the architecture to be rewritten when the integration is published. + +## Source and documentation captures + +The [source map](source-map.md) fixes the core compiler, operational documentation, Hello World blueprint and products, Service Directory family, and reusable distribution repositories. The inspection follows the principal operation paths and their collaborators. A repository snapshot being collected is not represented as a claim that every line in it was independently audited. + +The documentation repository supplies the authoring and operational context for mechanisms visible in source. Public examples make selected input/output correspondences inspectable. The supplemental source capture fixes the integrated extrusion behavior without introducing another public compiler repository into the publication. + +Historical implementation is separately pinned to root commit `ecf47809f960bd057af8a414168fada6fe22c5f7`, recorded on 30 January 2016 at 20:28:43 UTC. The current paper and every later feature are not retroactively assigned that date. + +## The maintained measurement record + +The author records repeated self-builds in which an approximately 30,000-line exported JCB blueprint produces an application exceeding one million lines in approximately 60–64 seconds on the demonstrated setup. Compiler rules, templates, reusable Powers, libraries, and assets participate as additional inputs. + +The paper preserves this as an engineering measurement record. It does not assign a hardware configuration or per-run data that was not supplied. The inspected timer boundary and the separately counted pinned repository snapshots are identified in [performance](../engineering/performance.md). A new reproducible run package can add its environment, blueprint, output inventory, and individual timings to that record. + +Output volume, compilation elapsed time, and hypothetical manual development effort are different measurements. Compiler-produced estimates based on seconds per line or file are not relabeled as measured hours saved. + +## Mathematical scope + +The formal account introduces explicit identities, contexts, contributions, state transitions, request graphs, binding sequences, and representation equivalences. Its propositions state assumptions for the mechanism being described. Finite request traversal, safe contextual reuse, prescribed-sequence repeatability, and transport preservation are separate results. + +A source path corresponds to a proposition where the path meets its assumptions. The model does not replace ordered mutation with a fictional immutable state, infer global transactions from ordered writes, or turn every generated region into a universally invertible transformation. + +The mathematical contribution of the publication is the explicit account of this architecture's relationships and operations. Established proof techniques and related systems are credited in the [bibliography](bibliography.md). + +## Authorship and originality + +The development account records the author's independent construction of JCB and its subsequent refactoring and maintenance. Retrospective correspondences to earlier research are acknowledged as correspondences, not invented influences. Independent development and first historical invention are different claims. + +Application authors retain their attribution. In particular, the Service Directory example names Lemuel van der Merwe as its application author. Joomla and reusable third-party works retain their own authorship and licenses. The paper's account of JCB does not claim ownership of those works. + +## Using this edition + +The main reading path describes what the system does and how its operations fit together. The [source map](source-map.md), [verification guide](../engineering/verification.md), [citation information](citation.md), and [publication details](publication.md) support reproducible examination. Each article has an exact Markdown alternate, and complete downloadable editions are generated from the same source. + +The intended use is understanding and reuse: another engineer should be able to identify a represented decision, follow its transformation, examine the mathematical relation, and implement the same architectural choice in a different technology. diff --git a/DOCS/reference/glossary.md b/DOCS/reference/glossary.md new file mode 100644 index 0000000..0ab7bed --- /dev/null +++ b/DOCS/reference/glossary.md @@ -0,0 +1,102 @@ +--- +title: Architectural glossary +description: Product terms and language-neutral concepts used consistently throughout the white paper. +section: Reference +order: 93 +evidence: Terminology derived from implementation roles and established computer science +--- +# Architectural glossary + +The terms below identify roles in the architecture. Where JCB uses a product-specific name, its general engineering meaning is given alongside it.

Files, language catalogues, supporting assets, manifests, and archives are artifacts. A file can exist before its final binding and injection stages are complete. [Materialization](../generation/materialization.md) + +## Blueprint + +The portable design representation: selected entity properties, typed identities, relationships, dependencies, authored code, and assets. Repository indexes and README descriptions locate or explain that design; they are counted separately from its payloads. [Representation](../blueprints/representation.md) + +## Build context + +The values that qualify an operation, including target, extension, view, generation role, language destination, active bindings, and occurrence settings. Runtime users and application data are a different context supplied when the generated application runs. [Context](../foundations/context.md) + +## Compilation + +The coordinated acquisition, interpretation, contribution, staged binding, code placement, and materialization of a represented application. The complete execution includes constructor preparation, later file updating, diagnostics, and packaging. [Execution](../compiler/execution.md) + +## Contribution + +A result of interpreting a definition's use: a store, key, update operation, and value. It may be schema data, a language entry, a query alias, a fragment, a requirement flag, or deferred work. Contributions are not all strings or immutable facts. [Classification](../compiler/classification.md) + +## Definition + +Reusable design knowledge with typed identity. A field, view, Power, template, or query definition can participate in several uses. Its identity differs from a local database row number and from a final output path. [Identity](../foundations/identity.md) + +## Deferred work + +An operation retained with its arguments because its required information will be ready later. JCB's selected admin replay and configuration-fieldset passes are examples. It differs from acquiring a definition lazily or binding a placeholder late. [Deferred work](../compiler/deferred-work.md) + +## Dependency + +A typed relationship or resource requirement exposed by an entity's schema, association, recognized embedded reference, or asset configuration. Incoming owned children and outgoing shared references can have different reset policies. [Dependency traversal](../blueprints/dependencies.md) + +## Dispenser + +JCB's role- and context-indexed store for prepared code. Retrieval can apply the active placeholder environment, add surrounding material, and remove consumed content. It is not merely a cache of final output strings. [Custom code](../compiler/custom-code.md) + +## Dynamic Get + +JCB's structured query/retrieval definition. It describes sources, selections, aliases, joins, filters, ordering, and result roles that are compiled into model code. Runtime query values remain inputs to the generated application. [Queries](../generation/queries.md) + +## Extrusion + +Recovery of represented model information from an existing component or class library. Discovery, static readers, precedence, identity resolution, reviewable candidates, and writers return supported structure to JCB's editable definitions. It differs from importing an explicit blueprint. [Extrusion](../extrusion/overview.md) + +## GUI-linked region + +A generated code region associated with a local table, property, and record address so eligible edits can be recovered. Its local numeric address is not the portable identity of the application model. [Custom-code trace](../examples/custom-code-trace.md) + +## Infusion + +The implementation's name for preparing and coordinating generated content. It invokes interpretation and creators, establishes shared and contextual bindings, and completes selected deferred work. The term is retained when naming the source service, not required of a reimplementation. [Execution](../compiler/execution.md) + +## Initialization and reset + +Initialization ordinarily preserves an acceptable local definition and acquires one where missing. Reset explicitly requests refresh; owned incoming children and referenced reusable definitions follow their respective recursive policies. These operations are not interchangeable overwrite modes. [Import](../blueprints/import.md) + +## Intermediate representation + +Information retained between input acquisition and final output. JCB uses structured records, specialized builders, flags, code fragments, and binding maps. Calling these intermediate representations identifies their role without attributing the structural guarantees of a typed AST or SSA system. [Stores](../compiler/stores.md) + +## Occurrence + +A definition's particular use under an association, placement, and context. Two views can reuse one field while assigning different roles or layout positions. The occurrence is not necessarily a separately allocated object in the implementation. [Identity](../foundations/identity.md) + +## Placeholder and binding environment + +A placeholder identifies text to be replaced using an applicable environment. JCB's environments and action modes have ordered replacement semantics, including original-input filtering in action 3. A binding stage is the point at which a selected environment is applied. [Binding](../compiler/binding.md) + +## Power and Joomla Power + +A Power is a managed reusable code definition with stable identity, dependencies, namespace, and placement behavior. A Joomla Power represents a version-sensitive platform class mapping. Both connect stable references to context-appropriate symbols, but their payloads and generation roles differ. [Powers](../compiler/powers.md) + +## Recollection + +An explanatory term for retrieving identified retained information when a consumer needs it, sometimes with further acquisition or contextual processing. It denotes a software operation here, not a claim about biological memory. The precise store and retrieval contract should be named whenever ambiguity matters. + +## Reconciliation and recovery + +Returning designated authored changes to managed design state under the implementation's identity and transformation rules. Fingerprint placement and commented fallback distinguish executable placement from recoverability. This is not a general automatic three-way merge or an inverse for arbitrary source edits. [Transport](../formal/transport.md) + +## Semantic classification + +Interpreting a definition in context and routing its different consequences to concern-specific consumers. It is not an ordinary sorting algorithm over comparable values. Schema, query, form, policy, language, and code-placement consequences can arise from the same occurrence. [Classification](../compiler/classification.md) + +## Target + +The platform and generation conventions selected for output. It differs from the host running the compiler and from the application's own version number. Target-specific emitters and Joomla Power mappings carry shared adaptation knowledge. [Targets](../compiler/targets.md) + +## Trace and equivalence + +A trace records an ordered sequence of operations or source-to-output correspondences. An equivalence states which observations a comparison preserves: portable design, normalized artifacts, or raw bytes. A local identity or date difference can matter to one comparison and not another, but the rule must be declared.

Include inherited Infusion work when tracing the constructor. + +## C02 + +**Shared services, configuration, and extension boundaries.** [Compiler/Factory.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Factory.php), `Compiler/Config.php`, and the [compiler service providers](https://github.com/joomengine/Joomla-Component-Builder/tree/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Service) connect shared stores and selected collaborators. Event interfaces and calls in the consuming paths establish where handlers can affect state. Service lifetime and construction are part of execution. + +## C03 + +**Component acquisition and nested enrichment.** [Component/Data.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Component/Data.php), `Compiler/Component.php`, and `Compiler/Model/Adminviews.php` load the root, establish its registry, enrich configuration and code, and follow view occurrences into their referenced data. Examine the query and `energize()` sequence, not only the final returned object. + +## C04 + +**Field definitions, names, and contextual code.** [Field/Data.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Field/Data.php) implements ID/GUID indexing, local acquisition, guarded remote retry, field-type enrichment, and use-site custom-code processing. The [Field services](https://github.com/joomengine/Joomla-Component-Builder/tree/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Field), including `Name`, `UniqueName`, `TypeName`, and `Customcode`, supply naming scope and per-view contribution guards. Cached data can be processed and mutated; it is not represented as a universally pure GUID lookup. + +## C05 + +**Semantic classification.** [Creator/Builders.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Creator/Builders.php) is the central field-contribution trace: schema and keys, list membership, relations, titles and aliases, storage treatment, search, sorting, filters, layouts, languages, and component-field metadata. Inspect the branch conditions and update operations of each contribution. The Greeting title-to-index rule is in the schema-building branch. + +## C06 + +**Store operations and output environments.** [Abstraction/Registry.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Abstraction/Registry.php) supplies shared registry operations. [ContentOne.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Builder/ContentOne.php) models shared placeholder keys; [ContentMulti.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Builder/ContentMulti.php) partitions bindings by context. Specialised builders retain their own value and update meanings. + +## C07 + +**Content preparation and deferred completion.** [Helper/Infusion.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Helper/Infusion.php) prepares content, interprets views, replays `secondRunAdmin` operations and argument arrays, and invokes the second configuration-fieldset pass. `Compiler/Creator/ConfigFieldsets.php` implements the selected fieldset work. The source has a prescribed replay point, not a generic least-fixed-point scheduler. + +## C08 + +**Exact binding semantics.** [Placeholder.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Placeholder.php) defines ordinary ordered replacement, presence checking, original-input map filtering, active-placeholder updating, and marker construction. Action 3 filters map entries; it does not remove every unknown output token. The host replacement primitive is documented in [R12](bibliography.md#r12). + +## C09 + +**Custom, GUI, external, and recovered code.** [Customcode.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Customcode.php) coordinates expansion and discovery. The [Customcode services](https://github.com/joomengine/Joomla-Component-Builder/tree/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Customcode) include `Dispenser`, `Gui`, `Extractor`, `External`, and `Reverse`. They establish preparation/retrieval, local editing addresses, static extraction, content-history acceptance, and supported reversal. Final fingerprint placement and `loadEscapedCode()` are in C01's compiler. A missing file and an unresolved location in an existing file have different diagnostic paths. + +## C10 + +**Power acquisition, dependency processing, and injection.** [Power.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Power.php) and the [Power collaborators](https://github.com/joomengine/Joomla-Component-Builder/tree/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Power) handle GUID acquisition, recursive preparation, source placement, import aliases, and per-file injection. [JoomlaPower.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/JoomlaPower.php) selects target-sensitive platform mappings. Distinguish a processing guard from completed preparation and a definition's qualified name from a file-local alias. + +## C11 + +**Nested template and layout acquisition.** [Templatelayout/Data.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Templatelayout/Data.php) recognizes supported literal load/render forms, resolves aliases, stores templates/layouts under their respective scopes, and follows nested content. Its recognized syntax defines the discovered dependency relation. + +## C12 + +**Dynamic Get and alias/result structure.** [Dynamicget/Selection.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Dynamicget/Selection.php), `Compiler/Dynamicget/Data.php`, and `Compiler/Model/Dynamicget.php` prepare sources, selections, aliases, joins, filters, and method-specific mappings. Query execution remains a runtime operation in the generated application. + +## C13 + +**History and update contributions.** [Model/Updatesql.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Model/Updatesql.php), `Historycomponent.php`, `Historyadminview.php`, and `Sql.php` in the same model directory process supported old/new relationships and properties. They contribute migration information; compiling that information is not the later execution of an installation migration. + +## C14 + +**Permission declarations and consumers.** [Creator/Permission.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Creator/Permission.php) prepares action mappings. [Helper/Interpretation.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Helper/Interpretation.php) contains the generated form treatment, field options, strict result processing, and permission-sensitive JSON save path. Inspect the respective branches around lines 4,030, 15,436–15,700, and 16,808 onward. Their conditions differ; a hidden input is not equivalent to removing data from every runtime result. + +## C15 + +**Language collection and output.** [Language.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Language.php) and [Language services](https://github.com/joomengine/Joomla-Component-Builder/tree/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Language) implement keyed collection, extraction, source/translation maintenance, association updates, inclusion thresholds, and messages. `Set`, `Update`, `Translation`, `Insert`, `Purge`, and `Multilingual` have separate responsibilities. + +## C16 + +**Router modeling and emission.** [Model/Router.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Model/Router.php) prepares view/key/alias data. [Creator/Router.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Creator/Router.php) selects default, configured, or authored work; `RouterConstructorDefault`, `RouterMethodsDefault`, and their manual counterparts implement those selected paths. + +## C17 + +**Module content.** [Joomlamodule/JoomlaSix/Infusion.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Joomlamodule/JoomlaSix/Infusion.php) establishes module context and prepares provider, dispatcher, Dynamic Get, helper, default template, installer, fieldset, and manifest content. Data and structure services and the architecture provider supply the corresponding acquisition and target responsibilities. + +## C18 + +**Plugin content.** [Joomlaplugin/JoomlaSix/Infusion.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Joomlaplugin/JoomlaSix/Infusion.php) establishes plugin naming and language context and prepares extension, provider, installer, fieldset, and manifest material. Plugin group, base-class, method, and property definitions participate through their data paths. + +## C19 + +**File inventory and ordered updating.** [Extension/Files/Updater.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Extension/Files/Updater.php), `Extension/Files/Dynamic.php`, and [Extension/FileContent.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Extension/FileContent.php) establish file-family order, context selection, shared-before-context binding, later code processing, injection, writing, and autoloader completion. + +## C20 + +**Packaging and configured publication.** C01's `Compiler.php` contains the final language/update/README/repository operations and component, module, and plugin archive paths. Structure and utility collaborators manage the associated file trees. These are operation-specific outcomes, not an asserted distributed transaction. + +## C21 + +**Target dispatch.** [Service/ArchitectureModule.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Service/ArchitectureModule.php) provides a concrete target-selection example. The same directory contains `ArchitectureController`, `ArchitectureView`, `ArchitectureComponent`, `ArchitecturePlugin`, `ArchitectureDashboard`, and `ArchitectureModel`. Inspect target configuration before service resolution and the lifetime of cached selection. + +## C22 + +**Generated design metadata.** C05's `Creator/Builders.php` assembles the component-field map. The [Hello World Table class](https://github.com/vast-development-method/hello-world-joomla-component/blob/a81c0dd8b8f41905671a86796a3e5995685fdaba/libraries/jcb_powers/JCB.Joomla/src/Helloworld/Table.php#L73-L96) shows the emitted Greeting GUID, type, roles, tab, and database properties. + +## C23 + +**Historical implementation.** [Root commit](https://github.com/joomengine/Joomla-Component-Builder/commit/ecf47809f960bd057af8a414168fada6fe22c5f7), 30 January 2016 at 20:28:43 UTC, and its [admin/helpers/compiler.php](https://github.com/joomengine/Joomla-Component-Builder/blob/ecf47809f960bd057af8a414168fada6fe22c5f7/admin/helpers/compiler.php). The early source already contains specialised builders, static/dynamic content stores, acquisition, structure construction, and later file updates. Later features and this manuscript are not backdated to that commit. + +## C24 + +**API and AJAX generation.** The [Joomla 4 compiler templates](https://github.com/joomengine/Joomla-Component-Builder/tree/bca4a1520484f3e2c2fbd12964a5995b0d058de1/admin/compiler/joomla_4) include API controller and JSON-view material. C07's Infusion establishes the API bindings; [Model/Ajaxadmin.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Compiler/Model/Ajaxadmin.php) prepares selected AJAX input and method contributions, flags, and tokens. Entry registration and runtime authorization must be read in their respective generated integration paths. + +## B01 + +**Entity catalogue and transport schema.** [Componentbuilder/Factory.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Factory.php) records the canonical entity map. [Package entity configurations](https://github.com/joomengine/Joomla-Component-Builder/tree/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Package) declare identifying fields, child relationships, indexes, payload paths, projection/encoding, and ignored local properties. `Package/Field/Remote/Config.php` and `Package/AdminView/Remote/Config.php` are representative cases. Distribution-channel flags are not interchangeable with every handler's retrieval eligibility. + +## B02 + +**Graph acquisition and publication dispatch.** [Package/Builder/Get.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Package/Builder/Get.php) and [Set.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Package/Builder/Set.php) select handlers, drain entity batches, distinguish reset policy, process files/folders, and aggregate results. Empty queues and successful persistence remain different observations. + +## B03 + +**Dependency extraction and tracking.** [Package/Dependency/Resolver.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Package/Dependency/Resolver.php), `Package/Dependency/Tracker.php`, and `Remote/SetDependenciesTrait.php` handle outgoing references, incoming children, recognized dynamic content, nested fields/rules, and asset queues. Edge direction affects subsequent operation policy. + +## B04 + +**Repository selection.** [Abstraction/Grep.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Abstraction/Grep.php), `Componentbuilder/Remote/Grep.php`, and `Componentbuilder/Package/Grep.php` establish configured-source traversal, index caching, item matching, and payload location. Trace selection and fetching separately when determining fallback behavior. + +## B05 + +**Portable export and remote updates.** [Abstraction/Remote/Set.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Abstraction/Remote/Set.php) and [Componentbuilder/Remote/Set.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Remote/Set.php) prepare payloads, dependencies, item descriptions, index updates, and eligible per-repository writes. Their normalization and unchanged-content checks differ from raw database-row comparison. + +## B06 + +**Remote initialization and local persistence.** [Componentbuilder/Remote/Get.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Remote/Get.php) coordinates local-preservation and retrieval behavior. [Data/Item.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Data/Item.php) supplies table-aware item persistence. Examine the return values of individual operations before assigning a stronger meaning to aggregate result buckets. + +## B07 + +**File and folder transport.** [Package/Remote services](https://github.com/joomengine/Joomla-Component-Builder/tree/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Package/Remote) include `GetContent`, `GetFile`, `GetFolder`, `SetContent`, `SetFile`, and `SetFolder`. They normalize resource identities, locate repository content, interpret target destinations, and retain the distinction between ordinary and forced acquisition. + +## B08 + +**Repository definitions.** [Repository/Remote/Config.php](https://github.com/joomengine/Joomla-Component-Builder/blob/bca4a1520484f3e2c2fbd12964a5995b0d058de1/libraries/vendor_jcb/VDM.Joomla/src/Componentbuilder/Repository/Remote/Config.php), the repository services, and E06's repository-index snapshot describe managed source configuration. Read/write branches and channels are inputs to discovery and publication, not properties inferred from an entity's short name. + +## X01 + +**Integrated component extrusion.** The captured implementation under `Componentbuilder/Extrusion/` includes `Extruder.php`, `Config.php`, discovery/layout adapters, typed registries, resolvers, and writers. `harvest`, `candidates`, and the writing operation separate observation, pairing, and persistence. The capture is identified by file SHA-256, independently of any moving branch: + +| File | SHA-256 | +| --- | --- | +| `Extruder.php` | `9f7bc95ba0d3912b40cbb0f14a689371523c46c26dc1c14e5a8513277521e1c6` | +| `Config.php` | `7aef639bbb031d7f8e487b0b78acbfa59169c806472462657c6c7bba38246476` | + +These are implemented edition-scoped operations, not paths asserted to exist at the older core compiler pin. Release availability is determined by the [official project](https://github.com/joomengine/Joomla-Component-Builder). + +## X02 + +**Static readers and property precedence.** Under the same capture, reader services examine schema, form, language, manifest, table metadata, and view artifacts. `Resolver/Precedence.php` selects each usable property's value and origin by configured rank and stable default tier order. Its SHA-256 is `81665ea7c80df6506ad5fe1699c9e1348bdb4c35f293c748455326d2d752ac6b`. Zero and false are admitted values; null and empty string are omitted. The reader grammars define recovery coverage. + +## X03 + +**Class recovery and reusable Power assembly.** Capture paths and SHA-256 values: + +| File | SHA-256 | +| --- | --- | +| `Powers/Extruder.php` | `3d572f1ffb82b1ed7badab938ef5cffa1a2333ab7d855c2ad1ce030f3aa3c44c` | +| `Powers/Reader/ClassFile.php` | `4a59011afdbae2d29b95341e10716170f65099cc360b9d7c7c9eee73552e2635` | +| `Powers/Resolver/Namespacer.php` | `4e78fe939ebdeb66fd4a9e66b5d168446325275abf65d20b6682ce9238771e06` | +| `Powers/Assembler.php` | `bffa8682f55257f03b41e0caac15ad152c6a269350ad35ebcdf4acc2e64aa879` | + +The trace covers declaration location, body extraction, namespace/path interpretation, supported placeholder/language reversal, relationship assembly, and selected writes. Lexical recognition is distinguished from the declaration forms fully represented by the destination model. + +## X04 + +**Pairing and write order.** `Resolver/Pairing.php` (SHA-256 `0dc7f59d0c1d85b4840ec07e116498ad2a7ac528e0c30565e8049605e8610e3d`), `Resolver/Candidates.php`, `Resolver/Sharing.php`, `Resolver/Reuse.php`, and `Writer/Dispatcher.php` (SHA-256 `d0de812634c16ad2a14805f5148a43806cbb5fae339214cc50bba5b39258cd84`) retain explicit verdicts, identity selection, shared-field decisions, and the dependency-compatible writer sequence. Each write and diagnostic has its own outcome. + +## E01 + +**Hello World blueprint.** [Snapshot](https://github.com/vast-development-method/hello-world-blueprint/tree/5802e7c1d9bfaac005c765ccda830a7d07cd7e12). Entity payloads under `src/`, child records, `@dependencies`, indexes, README descriptions, and assets support the [worked lifecycle](../examples/hello-world.md). The accompanying [accounting](../examples/accounting.md) publishes separate categories. + +## E02 + +**Hello World component product.** [Snapshot](https://github.com/vast-development-method/hello-world-joomla-component/tree/a81c0dd8b8f41905671a86796a3e5995685fdaba). Forms, SQL, list/view/model code, language entries, Table metadata, installer, and GUI-code markers support the field and custom-code traces. + +## E03 + +**Site Redirect module product.** [Snapshot](https://github.com/vast-development-method/hello-world-joomla-module/tree/20be318a6163e253c2a9803434622467d6006709). Dispatcher, provider, template, manifest, language, and installer material demonstrate a distinct extension context. + +## E04 + +**Hello World Privacy plugin product.** [Snapshot](https://github.com/vast-development-method/hello-world-joomla-plugin/tree/6a785145ee84212fec65a53b7c6c362ab0f8b408).

Its compiler coordinates information that becomes available at different times and contributes to different output concerns. Reusable definitions are acquired by identity, interpreted in their occurrence contexts, and distributed into specialized intermediate stores. Deferred operations retain work until its prerequisites are established. Ordered binding and code injection then complete staged artifacts under target-specific conventions. + +This paper describes that implemented architecture and expresses its operations in language-neutral terms. The account connects GUI-authored intent, database definitions, repository blueprints, local-first dependency discovery, contextual compilation, installed-component extrusion, designated-code recovery, and regeneration. A public Hello World blueprint and its three generated products provide inspectable traces. A field's properties and association roles are followed into its database schema, form, list behavior, language entries, and generated metadata; marked code is followed from its source property to its generated location. + +The formal treatment distinguishes definitions, occurrences, contributions, and artifacts; models ordered effects; establishes finite guarded traversal under stated conditions; specifies exact binding semantics; and defines the equivalences relevant to blueprint transport and reconstruction. These abstractions make the design available for examination and implementation outside Joomla without discarding the behaviors that make its coordination work. + +## 1. The problem is coordinated detail + +A field called *Greeting* can be described with a type, name, label, database properties, and a few interface settings. Its use in a view adds decisions such as title status, list visibility, search, sorting, and placement. A working application needs the consequences of those decisions in several places: schema, queries, forms, model methods, language catalogues, list headers, metadata, and sometimes permission-sensitive data paths. + +The difficulty is not producing one form element. It is keeping the related implementations consistent while definitions are reused, contexts change, dependencies are discovered, and different output stages execute. A developer should not have to repeat one decision independently in every destination or manually reconstruct the relationship between its effects after a platform change. + +I developed JCB to make that recurring work explicit and reusable. The original implementation grew from solving the application-building problem directly. Its responsibilities were subsequently separated into specialized services while preserving the coordinated flow of definitions, intermediate results, and generated products. The public source lineage begins on 30 January 2016; this edition gives the implemented architecture a systematic account. [Development and provenance](foundations/provenance.md) + +The core subject is **contextual compilation**: reuse identified design knowledge, interpret each use under its actual context, retain its different consequences, and complete each output operation at the point its required information is available. Export, import, extrusion, and recovery connect that compiler to a continuing development lifecycle. [C01–C07](reference/source-map.md#c01) + +## 2. Structured intent is an executable design description + +JCB's GUI represents application intent through typed choices and relationships. Field types describe reusable kinds of controls; fields configure them; view associations establish their roles; views define data retrieval and presentation; components select those views and associated extensions. Authored code occupies designated roles where application-specific behavior is needed. + +The GUI is an authoring surface, not the semantic definition of compilation. The same represented intent can enter through a repository blueprint or recovered model. The database stores a local editable form of it. Normalization and interpretation connect that form to the compiler's rules. [Structured intent](foundations/structured-intent.md) + +Let an authoring input $u$ be normalized into design $D=N(u)$. For concern $k$ and target $T$, the compiler computes a projection + +$$ +P_{k,T}(D,\Gamma), +$$ + +where $\Gamma$ supplies the relevant occurrence context. The result can be structured data, code, a requirement, or no contribution when the selected feature is inactive. A searchable flag, for example, requests known search behavior; the compiler supplies its implementation conventions rather than inferring an unstated business rule from the field's label. + +A compact blueprint is effective because reusable knowledge also resides in the compiler, templates, target rules, Powers, and supplied libraries. Generated size therefore measures the materialized combination of design and reusable implementation knowledge, not information produced from the blueprint alone. + +## 3. Four objects must remain distinct + +A **definition** is reusable knowledge. An **occurrence** is its use under an association and context. A **contribution** is a result retained for a particular generation concern. An **artifact** is a staged or completed output. + +A portable identity is a typed request + +$$ +u=(t,k,v), +$$ + +where $t$ is the entity type, $k$ its identifying field, and $v$ its normalized value. Many entities use GUIDs; custom code can use a function-name alias; owned children can use a parent relationship key. A local database primary key is a realization of that identity, not necessarily its portable value. + +An occurrence can be represented as + +$$ +o=(u,p,a), +$$ + +with use position $p$ and association settings $a$. Its context includes target, extension, view or use-site, generation role, language destination, active bindings, and additional settings. JCB carries these dimensions through records, service arguments, configuration, and scoped store keys. The mathematical tuple describes the role without requiring a matching allocated object. [Identity](foundations/identity.md), [context](foundations/context.md) + +Interpretation produces an ordered contribution sequence: + +$$ +J(d,\Gamma)=\langle c_1,\ldots,c_m\rangle, +\qquad c_i=(s_i,k_i,\omega_i,v_i). +$$ + +Each contribution identifies a store, key, update operation, and value. A title binding can be set; a searchable field can be appended; a language key can be filled; a code fragment can be concatenated; an operation can be deferred. These are different updates, even where the physical stores use similar registry machinery. + +The output relation is many-to-many. One field can affect several files; one model file can combine many fields, joins, policies, and custom fragments. Counting definitions, occurrences, contributions, and artifacts as if they were the same objects would hide the architecture's actual expansion. + +## 4. Portable blueprints form a discoverable graph + +A blueprint repository contains authoritative payloads and supporting distribution material. Payloads carry design properties, code, associations, and dependency descriptors. Indexes locate those payloads. Generated Markdown describes them. Assets supply referenced content. The entire repository is not counted as if every README paragraph were another compiler input decision. [Blueprint representation](blueprints/representation.md) + +Export selects a root and traverses its supported relationships. Type-specific configuration determines identifying fields, portable properties, child records, encoding, indexes, and asset targets. Installation-specific fields can be omitted. The writer then creates or updates payloads, readable item descriptions, and merged indexes in eligible repositories. Writes have per-item and per-repository outcomes rather than an assumed global transaction. [Export](blueprints/export.md) + +Import follows the opposite representation boundary. Ordinary initialization first preserves an acceptable local definition. Where missing, it selects an applicable configured repository entry, retrieves and maps its payload, persists it locally, and follows discovered dependencies. Reset is an explicit refresh operation. Incoming owned child records and outgoing reusable references can follow different recursive reset policies. [Import and reset](blueprints/import.md) + +The inspected entity catalogue contains 45 canonical types: components and their associations, modules, plugins and class-related definitions, admin and site views, fields, field types, validation rules, layouts, templates, Dynamic Gets, custom code, libraries, placeholders, Powers, repositories, and snippets. File/folder content has separate handlers. This common acquisition structure is broader than Power retrieval alone. [Entity catalogue](blueprints/discovery.md), [B01](reference/source-map.md#b01) + +“Global” discovery is bounded by the configured sources. Their order, branches, channels, and indexes determine selection. The inspected lookup selects an index match before fetching its payload; a failed selected payload does not automatically imply that every later repository will be tried. Once accepted, the definition becomes local editable knowledge, not transient text available only to one template. + +## 5. Dependency completion is controlled discovery + +Resolving one request can reveal others. A component points to view associations; an association points to a view; the view points to fields; fields point to types and rules. Recognized code references, nested subforms, templates, layouts, and assets add further edges. + +Let $R_0$ be root requests and $\operatorname{deps}(u)$ the relation extracted by the supported resolver. The reachable set satisfies + +$$ +R_{i+1}=R_i\cup\bigcup_{u\in R_i}\operatorname{deps}(u). +$$ + +For a finite reachable universe, this reaches the least dependency-closed set containing the roots. The production traversal uses nested handlers and queue drains. It retains attempted-request state so a shared or cyclic dependency does not cause endless reacquisition. [Dependency traversal](blueprints/dependencies.md) + +A small operational form is: + +```text +pending := normalized roots +attempted := empty +while pending is not empty: + request := remove the next request + if request has not been attempted: + mark it before recursive work can re-enter it + acquire it under the selected local/repository policy + record the actual outcome + enqueue supported dependencies exposed by the result +transport accumulated file and folder requirements +``` + +If each handler completes and each first visit enqueues finitely many members of a finite universe $U$, the lexicographic measure + +$$ +(|U\setminus\mathrm{attempted}|,|\mathrm{pending}|) +$$ + +decreases: a first visit decreases its first component; a duplicate removal decreases the second. Cycles are compatible with termination. Successful completeness remains a separate condition: an attempted missing definition is not a resolved one, and local-preservation paths rely on their required dependencies already being available or discovered elsewhere. [Formal resolution](formal/resolution.md) + +This closure describes acquisition, not every operation in the compiler. Later semantic processing includes replacement, removal, code effects, and context changes that should not be recast as one monotone fact-accumulation algorithm. + +## 6. Compilation begins before the final run method + +The complete execution includes service resolution and constructor work. The compiler starts timing, initializes its working state, and invokes content preparation before its final orchestration method runs. The initializer recovers designated edits from installed targets before rebuilding the component and resetting the working output. It then establishes component data, version settings, utility dependencies, and structures. [Execution](compiler/execution.md), [C01](reference/source-map.md#c01) + +Acquisition enriches raw records into compiler-ready data. Field loading connects ID and GUID forms, obtains type properties, processes XML and validation, and handles selected storage and history information. Returning cached field data can also invoke per-view custom-code processing. The base definition and its use-specific effects therefore have different reuse boundaries. [Acquisition](compiler/acquisition.md) + +Physical structure can be created while later semantic work remains. Additional dependencies can appear during code expansion and final injection. The architecture's requirement is that an operation has the information it needs when it consumes it—not that one universal loading pass must finish before any file can exist. + +```mermaid +flowchart TD + A["Build request and target configuration"] --> B["Recover edits and acquire definitions"] + B --> C["Prepare structures and shared bindings"] + C --> D["Interpret occurrences and collect contributions"] + D --> E["Complete deferred operations"] + E --> F["Bind staged artifacts and resolve code references"] + F --> G["Languages, metadata, repositories, and archives"] + G --> H["Native products and diagnostic report"] +``` + +The arrows summarize the main responsibilities. Event handlers, nested acquisition, and extension-specific generation operate at their documented points within that order. + +## 7. The central mechanism is semantic classification + +A field's interpretation contributes to schema, keys, list membership, joins, title and alias roles, storage transformations, scripts, search, sorting, filtering, layout, language, and generated field metadata. Some branches are inactive for a particular field. Others depend on its view association rather than its reusable definition alone. [Classification](compiler/classification.md), [C05](reference/source-map.md#c05) + +The Hello World Greeting field makes the process concrete. Its reusable definition selects a text field, the name `greeting`, label `Greeting`, database type `VARCHAR(255)`, nullable storage, and explicit-index value zero. Its form properties include maximum input length 50 and default text `Some text`. Its admin-view association marks it as the title, searchable, sortable, linked, and first in the selected list/edit positions. + +The generated component contains the column, form field, qualified language key, list sorting, and a Table metadata entry carrying the same GUID. It also contains an ordinary index on `greeting` even though the explicit-index property is zero. The compiler derives that index from the field's title role under the applicable non-text branch. [Greeting trace](examples/field-trace.md) + +That result is not unexplained template inflation. The definition, occurrence, and rule together determine it. The schema emitter and metadata emitter consume the same interpreted key requirement, so the SQL and model metadata agree. + +Fan-out and fan-in are both essential. One occurrence distributes several consequences. Later, a query combines selections, aliases, joins, filters, ordering, and custom code; a form combines field definitions, placement, conditions, policy, and labels. Intermediate stores connect these producers and consumers without forcing each emitter to rediscover the model independently. + +## 8. Retained state has types, scope, and lifetime + +JCB uses several kinds of retained information: acquired definitions; concern-specific builders; prepared code in dispensers; shared and contextual binding maps; deferred operations; and guards against repeated work. Their physical similarity does not make their contracts identical. [Intermediate stores](compiler/stores.md) + +A store is modeled as a partial map $M_s:K_s\rightharpoonup V_s$. Its key can be a definition identity, view name, extension key, field name, or combined address. Its update can set, fill, append, concatenate, or remove. The current filename binding intentionally changes between files. A per-view script guard has a different lifetime from a portable field GUID. + +Safe reuse depends on the inputs actually read by an interpretation. If deterministic $J$ depends on definition version $d$, context projection $\pi_J(\Gamma)$, and dependency observation $z$, a sufficient key is + +$$ +\kappa_J=(\operatorname{id}(d),\operatorname{version}(d),\pi_J(\Gamma),z). +$$ + +Equal keys then identify equal relevant inputs and equal results. Omitting a language prefix or target dimension is valid only where the interpretation does not depend on it. Repeating a cached effect is another question: concatenating the same script twice still duplicates it, so either idempotence or a correctly scoped contribution guard is required. [Contribution algebra](formal/classification.md) + +These distinctions explain the useful “remember now, use later” behavior without a biological-memory claim. The compiler retains an identified representation and recalls or completes it at the consumer that has the required context. + +## 9. Deferred work preserves a discovered obligation + +Linked-view work can be recognized before the information needed to finish it is ready. The compiler records the operation and its arguments, completes the earlier admin and component work, and then replays the retained operations. Configuration fieldsets similarly have an explicit second pass after earlier contributions are available. [Deferred work](compiler/deferred-work.md), [C07](reference/source-map.md#c07) + +For deferred work $w$, the semantic readiness condition is + +$$ +\operatorname{req}(w)\subseteq\operatorname{avail}(\Sigma). +$$ + +The production sequence establishes this through designated phases. It need not encode a machine-readable prerequisite set on every entry or run a generic scheduler. What matters is the producer–consumer ordering and retention of the required information. + +Deferred execution, lazy acquisition, and late binding remain distinct. The first retains an operation, the second obtains a definition when needed, and the third supplies values in an appropriate output context. The compiler combines all three, but a single word such as *recursion* would not explain their different responsibilities. + +A fixed ordered sequence can be repeatable even where reordering its operations changes the result. Confluence is stronger than determinism. The formal model therefore preserves the source's order rather than demanding that every pair of updates commute. [Staging](formal/staging.md) + +## 10. Binding completes text in its destination context + +Shared bindings carry component-wide values and fragments. Contextual bindings carry view- or extension-specific material. Prepared custom code can remain parameterized until retrieval from the dispenser applies the current placeholders. Per-file processing supplies another ordered sequence of shared binding, contextual binding, selected code expansion, events, and Power injection. [Binding](compiler/binding.md) + +Within a pass, JCB uses ordered replacement. For $P=\langle(k_1,v_1),\ldots,(k_n,v_n)\rangle$, + +$$ +s_0=s,\qquad s_i=\operatorname{replaceAll}(s_{i-1},k_i,v_i). +$$ + +Later entries can process text introduced by earlier ones. The filtered action first removes map entries absent from the original input and then performs those ordered replacements. For `A → B`, `B → x`, ordinary replacement of `A` produces `x`, while filtered replacement produces `B`. For original input `A B`, both entries survive filtering and the result is `x x`. + +The exact distinction matters to another implementation. Simultaneous substitution or indefinite recursive expansion would be different semantics. The [executable companion](engineering/reference-model.md) tests the introduced-token cases directly. + +Multiple stages let a prepared fragment acquire its destination's name, namespace, language key, or role. They also establish an ordering obligation: a token introduced by one stage needs an applicable consumer after that stage if it is intended to be resolved during the build. The operation that owns that completion must be identifiable. + +## 11. Managed code joins identity to placement + +A Power reference identifies a reusable code definition without requiring the author to fix every file-local alias and output path at the reference site. The loader obtains the definition locally or through configured repository acquisition, prepares its relationships, and guards recursive loading. Injection resolves the qualified name, existing imports, short-name collisions, and required import statements in the destination file. [Powers](compiler/powers.md) + +The three identities are different: portable Power identity, target-qualified class name, and file-local symbol. Namespace and placement settings also determine whether code belongs in a reusable library location or an extension source role. A complete-class override is a deliberate ownership choice distinct from inserting a method fragment into a generated class. + +Joomla Powers add target-sensitive platform mappings. The same logical platform reference can select a namespace and type appropriate to the compile target. Architecture services separately select target-specific controller, model, view, module, plugin, and other emitter implementations. The host running JCB and the platform targeted by the output are not collapsed into one version variable. [Target selection](compiler/targets.md) + +Custom code also includes GUI-linked regions, reusable aliases, and explicitly accepted external resources. Preparation can expand those references and discover more Powers or language entries. The code is part of the compiler's information flow, not simply pasted into an arbitrary file after generation has finished. [Custom code](compiler/custom-code.md) + +## 12. Generation coordinates complete application concerns + +Schema generation retains normalized types, defaults, nullability, keys, storage treatment, and history-derived update information. Query generation retains source/result aliases, joins, predicates, result roles, and runtime filter structure. Form and layout generation combines field properties, occurrence order, tabs, conditions, validation, and nested presentation dependencies. Each uses decisions established elsewhere in the build. [Schemas](generation/schema.md), [queries](generation/queries.md), [forms](generation/forms-layouts.md) + +Permissions show why those interactions matter. Field-level options can alter form controls, remove fields, or select hidden treatment under their specific branches. Separately configured strict result handling can redact selected retrieved values. Save generation must distinguish a missing submitted value that should be cleared from a value absent because the current user was not allowed to edit it. Policy therefore affects declarations, presentation, result handling, and persistence together. [Permissions](generation/permissions.md) + +Language processing connects emitted keys to source strings and target catalogues. Translation maintenance reuses available records and applies selected inclusion thresholds. Router generation connects views to keys, aliases, and data sources. API and AJAX paths reuse established view identity, policy, input definitions, and authored method roles while retaining their own runtime integration contracts. [Languages](generation/languages.md), [entry surfaces](generation/routing.md) + +Components, modules, and plugins have distinct data, structure, context, content, and packaging paths. The Hello World module combines structured redirect configuration with authored redirect behavior; the compiler supplies its native module structure. The plugin's stored name contains a component placeholder; compilation resolves it under the component occurrence into its final plugin identity. [Extension trace](examples/extension-trace.md) + +Materialization completes staged files, resolves late code dependencies, supplies autoloading, writes language and installation metadata, and constructs archives. The output is a native application product. Normal application requests do not ask JCB's authoring GUI to interpret the blueprint again. [Materialization](generation/materialization.md) + +## 13. Extrusion returns existing structure to the model + +The integrated extrusion machinery accepts component roots and schema material, discovers relevant artifacts, and reads their represented structure without executing the application. Schemas, form XML, manifests, language files, table metadata, classes, and presentation files supply overlapping but different evidence. [Extrusion](extrusion/overview.md) + +Property resolution is explicit. Its default precedence is table metadata, SQL notes, XML, then derived schema information, with configurable ranks and a stable tie-break. Selection occurs per property and retains the winning value's origin. Zero and false are usable values; null and empty string are excluded by the selected rule. A database default and form default remain different properties. [Artifact analysis](extrusion/analysis.md) + +Harvest, candidate presentation, and writing are separate operations. Pairing decisions select create, update, or ignore. Sharing can consolidate compatible fields before associations are written. Writers follow dependency order so later records can refer to identities established earlier. Reports retain deliberate skips and unresolved details. + +Class extrusion locates supported named declarations, extracts their bodies, resolves namespace/path relationships, reconstructs supported imports and Power connections, and reverses applicable component or language specialization into reusable representations. The recovered definition then uses the ordinary compiler's acquisition, namespace, binding, and placement services. [Class recovery](extrusion/classes.md), [pairing](extrusion/pairing.md) + +Extrusion is not the unique inverse of every possible program. The same ordinary index can have arisen from an explicit index choice or from a title role; SQL alone cannot tell which. Additional metadata and review decisions select a usable model. The recovered model becomes explicit design knowledge for subsequent compilation and export. The [edition record](reference/edition.md) identifies this implemented integrated capability separately from the older core source pin. + +## 14. Transport, recovery, and regeneration preserve different things + +Let $\beta(D)$ be the normalized blueprint-relevant projection of local design. Define + +$$ +D_1\equiv_B D_2\quad\Longleftrightarrow\quad\beta(D_1)=\beta(D_2). +$$ + +A loss-preserving export/import pair, complete required dependencies and assets, consistent identity mapping, and an accepting existing-item policy preserve this relation. Local numeric IDs and intentionally omitted installation state can differ. Regenerated artifact equality additionally depends on target rules, reusable inputs, hooks, and environment observations. [Transport model](formal/transport.md) + +Designated-code recovery has another domain. GUI addresses and contextual fingerprints locate eligible authored regions. When a regenerated file's context still identifies the intended placement, the compiler restores the code there. Where an existing file's location cannot be established, it retains commented recovery material and reports the file and recorded location for repositioning. A missing target file has a separate diagnostic. + +For uniquely identified non-overlapping regions whose admitted bodies are preserved, extraction after emission returns the same region map. Where generation specializes text and recovery reverses it, the law concerns the canonical representation those transformations preserve. This is a local property of the selected recovery mechanism, not raw equality of entire arbitrarily edited applications. + +Regeneration connects these flows. A blueprint transported to another installation can be edited and compiled. A recovered model can join the same process. An authored region can re-enter the next build. The compiler remains the common operation that turns their resulting design knowledge into coordinated products. + +## 15. Self-generation and the maintenance multiplier + +JCB builds its own application from its blueprint and reusable inputs. Its generated application layers outside the library collection provide the authoring and Joomla integration through which definitions are managed and compilation invoked. The libraries include substantial supplied implementation, including compiler services. [Self-generation](engineering/regeneration.md) + +The self-build is + +$$ +A_J=\operatorname{compile}(B_J,L_J,\Theta_T,C,H), +$$ + +where $B_J$ is the application blueprint and $L_J$ the reusable library/Power input. Their different origins remain visible; the compiler coordinates their inclusion rather than authoring every library body during the build. + +The same separation supplies a maintenance multiplier. A change to a shared target rule can reach each model that consumes that rule on regeneration. A platform mapping can update references across several applications. A field decision can update several artifacts within one application. The propagation is determined by actual dependencies and ownership: authored complete-class replacements and arbitrary embedded code retain their own maintenance responsibilities. + +This effect can be inspected directly: identify the changed rule or definition, identify its consumers, regenerate, and compare the affected products. It does not need an invented labor estimate or a market-superiority assertion. + +## 16. Measurements and the cost of coordination + +Repeated maintained self-builds compile an approximately 30,000-line JCB blueprint into an application exceeding one million lines in approximately 60–64 seconds on the demonstrated setup. The compiler timer includes initialization and content preparation through the successful final packaging path. Reusable rules, templates, Powers, libraries, and assets are additional inputs. [Performance record](engineering/performance.md) + +The smaller public Hello World snapshot has 33 payload JSON files, 65,600 serialized bytes, and 1,298 physical payload lines. Its three generated repositories contain 32,988 physical text lines across 286 text files. Indexes, descriptions, binary assets, and repository metadata are counted separately. Escaped newlines inside JSON strings mean physical payload lines are not a measure of decoded program statements or manual effort. [Accounting](examples/accounting.md) + +A useful cost model separates acquisition, normalization, contextual interpretation, deferred completion, binding, writing, packaging, and effects. Reuse can replace repeated acquisition cost $na$ with one acquisition plus lookups while retaining the distinct contextual work. It does not remove the cost of writing $B$ required output bytes, which is at least $\Omega(B)$ in a byte-charging model. + +Retained state trades acquisition or recomputation against memory and lifecycle obligations. Ordered substitution can repeatedly scan intermediate strings; later expansion can change their size. Repository and local-cache conditions define different workloads. The paper's measurement method records those boundaries instead of using one output ratio as a universal performance conclusion. + +## 17. Operational semantics and reusable implementation boundaries + +The complete state can be represented as + +$$ +\Sigma=(q,D,K,O,M,W,P,A,X,\Delta), +$$ + +covering control position, local design, request state, occurrences, stores, deferred work, bindings, artifacts, external observations, and diagnostics. A transition changes its specified parts. A complete trace includes event handlers and external reads, not only built-in generation functions. [Operational state](formal/state.md) + +For fixed initial state, fixed relevant observations, deterministic operations, and a prescribed control policy, corresponding states remain equal by induction through the execution. This establishes repeatability of the explicit model without requiring all mutations to commute. The model also permits explicit failure, partial artifacts, and recovery diagnostics. + +An implementation in another language needs the same responsibility boundaries: typed model normalization; portable identity and resolution policy; contextual interpretation; typed contribution operations; scoped stores; deferred prerequisites; target dispatch; explicit binding semantics; staged artifacts; and separate transport/reconstruction contracts. It can use syntax trees instead of fragments, records instead of PHP registries, and another module system instead of PHP namespaces. [Implementation guide](engineering/implementation.md) + +A small complete vertical slice is the practical starting point. One field should produce consistent schema, form, query, and metadata; its portable identity should survive transport; changing its context should affect only the intended projections; and a missing dependency should produce a specific result. The executable companion makes selected mechanisms directly testable before a complete application generator is built. + +## 18. Intellectual context and conclusion + +Model-driven engineering explains the separation of intent and platform implementation. Attribute grammars and JastAdd provide close context for inherited, synthesized, referenced, and demand-evaluated information. MPS mapping labels exemplify retaining input-to-generated relationships for later consumers. Build-system research separates dependencies, scheduling, and rebuilding; memoization addresses repeated computation; modularity addresses change boundaries; bidirectional transformations and protected regions address selected update paths. [Related mechanisms and bibliography](reference/bibliography.md) + +These are retrospective connections to established work. They clarify the independently developed JCB architecture without erasing its provenance or treating every similar mechanism as the same complete system. + +The resulting account is a compiler-centered composition. Portable identities make definitions discoverable and reusable. Context gives each occurrence its proper interpretation. Specialized stores preserve distinct consequences. Deferred work separates discovery from readiness. Ordered binding and target-aware placement complete native products. Export, import, extrusion, and designated recovery return useful information to the same editable model. + +The public traces expose that composition at a small inspectable scale; the generated applications and maintained self-build expose its larger operational use. The mathematics names the relationships that make it coherent. Together they provide a basis for understanding the current implementation, reproducing its architectural choices elsewhere, and studying where a subsequent implementation can improve them. + +The [reading guide](reading-guide.md), [source map](reference/source-map.md), [formal vocabulary](formal/notation.md), and [verification guide](engineering/verification.md) provide the detailed continuation.
