*PromptDependencyResolution for MarkiTect*

# Functional Requirements Specification (FRS)

## MarkiTect Extension: PromptDependencyResolution Infrastructure

---

## 1. System Definition

The system shall provide infrastructure within MarkiTect to support structured execution of PromptTemplates using deterministic PromptDependencyResolution across InformationSpaces.

The system shall enable:

* Deterministic context compilation
* Controlled PromptRun execution
* Nested Generator runs
* Idempotent execution via InputBundleHash
* Dependency graph construction
* Incremental recomputation with depth control
* RunManifest persistence and inspection
* QualityGate validation and impact tracking

---

## 2. Functional Scope

The system shall operate within a MarkiTect workspace and extend existing InformationSpace capabilities to support executable knowledge artifacts.

The system shall not prescribe:

* LLM provider implementation
* UI layout specifics
* Storage backend architecture
* Internal algorithm selection

---

# 3. Functional Requirements

---

## FR-1: InformationSpace Addressability

**FR-1.1**
The system shall allow content artifacts within an InformationSpace to be uniquely addressable by name and persistent identifier.

**FR-1.2**
The system shall compute and store a content digest for each artifact upon modification.

**FR-1.3**
The system shall allow referencing artifacts across multiple InformationSpaces.

---

## FR-2: PromptTemplate Definition

**FR-2.1**
The system shall allow defining a PromptTemplate as a content artifact containing ContentMacros.

**FR-2.2**
The system shall detect and extract ContentMacros during TemplateAnalysis.

**FR-2.3**
The system shall support the following ContentMacro kinds:

* Required
* Optional
* Generate

---

## FR-3: PromptResolver Behavior

**FR-3.1**
The system shall resolve ContentMacros in a deterministic resolution order:

1. Local InformationSpace
2. Explicitly included InformationSpaces
3. Default InformationSpace
4. Team/Shared InformationSpace (if configured)

**FR-3.2**
The system shall mark unresolved Required macros as failure conditions.

**FR-3.3**
The system shall allow Optional macros to resolve to empty without failure.

**FR-3.4**
The system shall, for Generate macros:

* Identify a corresponding Generator PromptTemplate
* Initiate a nested PromptRun
* Persist generated artifact(s)
* Resume original resolution

**FR-3.5**
The system shall enforce a configurable maximum generation depth.

---

## FR-4: PromptRun Lifecycle

**FR-4.1**
The system shall support PromptRun execution stages:

* TemplateAnalysis
* ContextCompilation
* PromptProcessing

**FR-4.2**
The system shall produce a CompiledPrompt during ContextCompilation.

**FR-4.3**
The system shall calculate an InputBundleHash consisting of:

* Template digest
* Ordered dependency digests
* Resolver configuration identifier
* Model settings
* Compilation options

**FR-4.4**
The system shall skip execution if a prior successful PromptRun with identical InputBundleHash exists, unless explicitly overridden.

---

## FR-5: RunManifest Persistence

**FR-5.1**
The system shall persist a RunManifest for each PromptRun.

**FR-5.2**
The RunManifest shall include:

* Template metadata
* Resolved inputs and their digests
* CompiledPrompt digest
* Model configuration
* Output artifacts and digests
* Dependency edges
* Validation results
* Impact debt records (if applicable)

**FR-5.3**
The system shall link nested Generator runs to parent PromptRuns.

---

## FR-6: Dependency Graph Construction

**FR-6.1**
The system shall record directed dependency edges between produced artifacts and their input artifacts.

**FR-6.2**
The system shall construct a dependency graph across InformationSpaces.

**FR-6.3**
The system shall detect circular dependencies.

---

## FR-7: Incremental Recompute

**FR-7.1**
When an artifact is modified, the system shall identify dependent artifacts via the dependency graph.

**FR-7.2**
By default, the system shall recompute direct dependents only (depth = 1).

**FR-7.3**
If recomputation would create a circular dependency or exceed depth limits, the system shall suppress further recompute.

**FR-7.4**
The system shall record suppressed recomputations in the RunManifest.

---

## FR-8: Change Impact Assessment

**FR-8.1**
The system shall calculate a change magnitude metric when an upstream artifact changes.

**FR-8.2**
The system shall support configurable methods for change magnitude calculation:

* Structural diff ratio
* Content diff ratio
* Embedding distance (optional)
* LLM-assessed impact (optional)

**FR-8.3**
The system shall record impact assessments as ImpactDebt entries in the RunManifest when recomputation is suppressed.

---

## FR-9: QualityGate Validation

**FR-9.1**
The system shall support schema validation against generated artifacts.

**FR-9.2**
The system shall allow multiple QualityGates per artifact.

**FR-9.3**
The system shall record pass/fail results and validation diagnostics in the RunManifest.

**FR-9.4**
The system shall support halting policies based on QualityGate results.

---

## FR-10: Halting and Refinement Policy

**FR-10.1**
The system shall support configurable QualityPolicies.

**FR-10.2**
The system shall evaluate halting decisions based on:

* QualityGate results
* Marginal improvement metrics
* Iteration limits
* Resource budgets (e.g., number of runs)

**FR-10.3**
The system shall record halting decisions in the RunManifest.

---

## FR-11: Traceability and Auditability

**FR-11.1**
The system shall enable traceability from any artifact to:

* Producing PromptTemplate
* Input artifacts
* Generator runs
* Quality validation results

**FR-11.2**
The system shall enable recomputation based on changes in any dependency.

---

# 4. Out of Scope

The following are explicitly excluded from this FRS:

* User interface design and layout
* Internal storage architecture
* LLM provider selection
* Model training or fine-tuning
* Visualization tooling
* Economic or incentive mechanisms

---

# 5. Acceptance Criteria

The system shall be considered compliant when:

1. A PromptTemplate referencing Required, Optional, and Generate macros can be executed.
2. Missing Generate dependencies are automatically generated and persisted.
3. Re-running an unchanged PromptRun with identical InputBundleHash results in a skipped execution.
4. Changing an upstream artifact triggers recomputation of direct dependents.
5. Circular recomputation is suppressed and logged.
6. RunManifest contains complete provenance and dependency information.
7. Schema validation failures are correctly recorded and influence halting policy.

---

# 6. Architectural Positioning

This infrastructure operates:

* Above artifact storage
* Below UI interaction layers
* Orthogonal to LLM provider implementation
* As an execution engine inside MarkiTect

It provides the functional backbone required for executable InformationSpaces within Coulomb Social.
