Every algorithm contract in this domain is listed with its position on the derivation loop, its intent and invariant, the flow it walks, its productions as a grammar, what it composes and is composed by, which forces and principles it answers to, what grounds it and what it grounds, and an exemplar where the record carries one. The diagram shows what composes what inside the domain.

### Document Truth Alignment

- Math type: [logic](https://banes-lab.com/records/reason/math-type-logic.md)
- Yields: boolean

Details

Intent
For any document that states facts about a codebase, separate invariant facts (counts, paths, names, and the doc-type's structural schema) from variant prose, bind each invariant to a code-derived value through a stable key, compile the document from a template, and gate the output so a stated fact can never drift from the code it describes.

Invariant
A document is well-formed iff every rendered invariant equals its resolved code-truth and every doc-type-required meta-concern is present in order; prose is free.

Flow

```text
Concern → Variant → Invariant → TruthKey → Deriver → Template → Compilation → DriftGate
```

Productions

```bnf
DocumentTruth ::= <VariantProse> "+" <InvariantSet> "->" <TruthKeyBinding> "->" <DeriverResolution> "->" <TemplateCompilation> "->" <DriftGate>
InvariantBinding ::= <TruthKey> "," <TokenSlot> "," <DerivedValue> "," <DocTypeSchema>

Grounds

```text
A doc states 'the system has 12 modules' — a hand-typed count that drifts the moment a module is added.
```

After

```text

```

### Architectural Contract Kernel

- Math type: [computation](https://banes-lab.com/records/reason/math-type-computation.md)
- Yields: procedure

Details

Intent
For any programmatic system, identify architectural concerns, define explicit contracts for each concern, bind implementations to those contracts, validate invariants, observe behavior, and evolve through versioned change.

Invariant
Architecture is a graph of bounded contracts whose nodes expose stable intent and whose edges preserve compatibility, causality, and governance.

Flow

```text
Concern → Boundary → Contract → Implementation → Verification → Observation → Evolution
```

Productions

- Yields: boolean

Details

Intent
Validate that every implementation of an abstraction preserves the abstraction’s behavior, accepts valid parent inputs, returns valid parent outputs, and does not strengthen forbidden constraints.

Invariant
Polymorphism is safe only when behavioral subtyping holds.

Intent
For any architectural concern, define its intent, boundary, contract, invariants, allowed variation, forbidden leakage, validation strategy, observability model, and evolution policy.

Invariant
Every architecture principle can be operationalized as a bounded contract with verification and change rules.

Intent → Boundary → Contract → Invariants → Variation → Validation → Evolution
```

### Architectural Contract Algebra

Details

Intent
<Classify architectural force> → <Declare boundary> → <Define contract> → <Choose pattern> → <Bind implementation> → <Verify invariant> → <Observe runtime> → <Govern evolution>

Invariant
Architecture becomes reproducible when every named principle is reduced to a force, every force becomes a contract, every contract has invariants, and every invariant has validation.

Flow

```text
Force → Contract → Pattern → Implementation → Verification → Operation → Evolution
```

Productions

### Manifest-Driven Documentation

- Math type: [computation](https://banes-lab.com/records/reason/math-type-computation.md)
- Yields: procedure

Details

Intent
For a module whose public surface is machine-derivable, make its metadata manifest the single documentation source of truth: authored narrative lives in mandated, shape-validated manifest fields (with self-expanding custom fields), the API surface is collected deterministically from the built type-declarations, one marker-layered document is compiled per module from both, and a governance router runs the context-detection rules on the manifest strings where a manifest governs (rendering each field to its markdown fragment first) and on the document itself where none exists. Beyond the module document, a manifest may declare typed documents — each a form plus concern that routes through the pure location function to a computed path — generated and drift-checked the same way, so the manifest is the single content generator with no separate template mechanism.

Invariant
A module's document is well-formed iff it recompiles byte-identical from its manifest docs-block plus its derived surface, its docs-block satisfies the mandated schema with every custom field a renderable shape, and every governed string passes the context rules reported at its manifest field; the manifest, where present, is the governed surface and the document is exempt and drift-checked.

Flow

```text
Manifest → AuthoredField → DerivedSurface → SectionDeriver → MarkerLayer → Compilation → GovernanceRouter → DriftGate
```

Productions

```bnf
ModuleDocument ::= <ManifestAuthoredFields> "+" <DerivedSurface> "->" <SectionDeriverResolution> "->" <MarkerLayerTemplate> "->" <Compilation> "->" <DriftGate>

```text

```

After

```text
manifest.docs{authored} + derivedSurface{from .d.ts} → section-derivers → marker-template → compile → drift-gate{recompiles byte-identical, else fail}
```

### Consumer Config SSOT

- Math type: [logic](https://banes-lab.com/records/reason/math-type-logic.md)
- Yields: boolean

Details

Intent
For any reusable package that must stay agnostic of the applications consuming it, hardcode zero consumer-specific truths in package source; declare every consumer-specific value in one consumer-owned config of typed sections, load it through a framework the leaf packages never import, and hand each package only the section it needs through an injection surface — so a package drops into any consumer without a literal about that consumer leaking through its source.

Invariant
A package is consumer-agnostic iff every consumer-specific value it depends on arrives by injection at wiring time and no consumer token, path, or config-location appears in its source; the one consumer config is the single reader-visible source of those values and a static gate rejects any re-hardcoding.

Flow

```text
ConsumerValue → ConfigSection → FrameworkLoad → InjectionSurface → PackageConsumption → CouplingGate
```

Productions

```bnf
ConsumerConfigSSOT ::= <ConsumerValueSet> "->" <ConfigSectionSet> "->" <FrameworkLoad> "->" <InjectionSurface> "->" <PackageConsumption> "+" <CouplingGate>

### Finite State Machine

- Math type: [graph](https://banes-lab.com/records/reason/math-type-graph.md)
- Yields: edge-list

Details

Intent
Model behavior as a finite set of states with explicit legal transitions, so illegal state combinations are unrepresentable.

Invariant
Every runtime state is one of the declared states and every transition is a declared edge.

Flow

```text
EnumerateStates → DefineEvents → DeclareTransitions → RejectUndeclared

function onClick() { isLoading = true; if (isOpen) isOpen = false; }
```

After

```typescript
type FooState = "closed" | "loading" | "open" | "error";
const transitions: Record<FooState, Partial<Record<FooEvent, FooState>>> = {
closed: { open: "loading" },
loading: { ready: "open", fail: "error" },
open: { close: "closed" },
error: { retry: "loading" },
};
function next(state: FooState, event: FooEvent): FooState { return transitions[state][event] ?? state; }
```

### Statecharts

- Math type: [graph](https://banes-lab.com/records/reason/math-type-graph.md)
- Yields: edge-list

Details

Intent
Extend a flat state machine with hierarchy and parallel regions, so independent concerns compose without state explosion.

Invariant
Independent behavioral concerns live in separate parallel regions rather than a cross product of flat states.

### Petri Nets

- Math type: [graph](https://banes-lab.com/records/reason/math-type-graph.md)
- Yields: edge-list

Details

Intent
Model concurrent flow as places, tokens, and transitions, so reachability and deadlock are analyzable before runtime.

Invariant
Concurrent progress is expressed as token flow through transitions whose enabling conditions are explicit.

Flow

```text
DefinePlaces → PlaceTokens → DefineTransitions → AnalyzeReachability → AssertNoDeadlock

{ name: "takeB", consume: { aHeld: 1 }, produce: { bHeld: 1 } },
],
});
assertNoDeadlock(reachableMarkings(net));
```

### Queuing Theory

- Math type: [probability](https://banes-lab.com/records/reason/math-type-probability.md)
- Yields: number[0,1]

Details

Intent
Size a system from arrival and service rates, so capacity and wait time are predicted rather than guessed.

Invariant
Utilization stays below one and predicted wait time is derived from the arrival/service-rate model.

Flow

```text
MeasureArrivalRate → MeasureServiceRate → ComputeUtilization → PredictWaitTime → SizeServers
```
