10 Quality Requirements | CX Documentation

Table of Contents

Quality Scenarios
Priority Rule

The architecture is optimized for:

determinism
reproducibility
auditability
extraction safety
trust-boundary clarity
documentation navigability

These requirements matter more than feature count. A smaller but provable system is preferable to a broader system with ambiguous boundaries.

Quality Scenarios

Quality Scenario Required behavior Evidence

Quality	Scenario	Required behavior	Evidence
Determinism	The same committed source tree is bundled twice.	Planning, ordering, render plan hashes, and checksums remain stable.	`verify`, render-plan tests, reproducibility checks.
Reproducibility	A release package is rebuilt from the certified commit.	Generated runtime output and release integrity metadata match the expected commit and version.	release integrity checks, double-build reproducibility lane.
Auditability	A reviewer asks why a bundle was trusted or dirty.	Manifest metadata records trust labels, dirty-state override evidence, note governance context, and derived review exports.	manifest schema, bundle manifest, audit log where applicable.
Extraction safety	A downstream process extracts files from a bundle.	Extraction follows manifest truth and verifies when requested; degraded recovery is explicit and never silent.	`extract --verify`, extraction safety docs, bundle validation tests.
Trust-boundary clarity	An agent produces useful live reasoning.	Track B output remains untrusted until Track A validation or verification proves an artifact.	system contracts, MCP policy, Friday-to-Monday workflow.
Documentation navigability	A new operator needs to choose the right command without reading every architecture page.	Manual pages provide entry points, while architecture pages explain the model and link to stable contracts.	Antora navigation, docs assurance tests, architecture overview.

Determinism

The same committed source tree is bundled twice.

Planning, ordering, render plan hashes, and checksums remain stable.

verify, render-plan tests, reproducibility checks.

Reproducibility

A release package is rebuilt from the certified commit.

Generated runtime output and release integrity metadata match the expected commit and version.

release integrity checks, double-build reproducibility lane.

Auditability

A reviewer asks why a bundle was trusted or dirty.

Manifest metadata records trust labels, dirty-state override evidence, note governance context, and derived review exports.

manifest schema, bundle manifest, audit log where applicable.

Extraction safety

A downstream process extracts files from a bundle.

Extraction follows manifest truth and verifies when requested; degraded recovery is explicit and never silent.

extract --verify, extraction safety docs, bundle validation tests.

Trust-boundary clarity

An agent produces useful live reasoning.

Track B output remains untrusted until Track A validation or verification proves an artifact.

system contracts, MCP policy, Friday-to-Monday workflow.

Documentation navigability

A new operator needs to choose the right command without reading every architecture page.

Manual pages provide entry points, while architecture pages explain the model and link to stable contracts.

Antora navigation, docs assurance tests, architecture overview.

Priority Rule

When a feature conflicts with a quality requirement, the quality requirement wins unless a documented, reviewed exception records the tradeoff. This is why dirty-state refusal, strict overlap handling, and latest-only schema publishing are allowed to be inconvenient: they keep the public contract honest.
