docs/ is Truthmark's repository documentation tree. It keeps repository-wide agent rules, reusable standards, current architecture, current lane-separated truth docs, and non-canonical research notes separate from onboarding copy.

AGENTS.md is the agent entry point, but it delegates repository-wide rules to docs/ai/repo-rules.md. README.md remains the human onboarding and product entry point. docs/user-guide.md owns detailed human-facing command, workflow, and configuration guidance. .truthmark/config.yml defines the committed hierarchy contract.

Scope

This doc defines the current structure, navigation map, and maintenance expectations of Truthmark's canonical docs/ tree.

Authority Source

Repository-wide conflict order and completion policy live in docs/ai/repo-rules.md. Use this index for navigation and document-class guidance; it does not restate the full authority hierarchy.

README.md may help with onboarding and positioning, but it must not override current-state docs or repository-wide agent rules.

Audience Split

Agent-centric docs

docs/ai/ for repository rules and agent onboarding
docs/truthmark/routes/ for routing metadata
docs/standards/ for reusable constraints and completion rules
docs/truthmark/product/ for product capability promises, boundaries, and acceptance criteria
docs/truthmark/engineering/ for current implementation behavior, architecture, contracts, workflows, and operations
docs/architecture/ for repository-specific architecture guardrails
docs/research/ for non-canonical research evidence, evaluations, and comparisons
docs/truthmark/templates/ for editable scaffold templates used to create new docs
docs/truthmark/engineering/contracts/ for stable contracts the CLI exposes

Human-centric docs

README.md for onboarding and positioning
docs/user-guide.md for detailed usage, command, workflow, configuration, routing, Portal, and example guidance

Directory Map

Path	Type	Primary audience	Purpose
`docs/ai/`	agent rules	agent	Repository-wide rules and fast onboarding
`docs/truthmark/routes/`	routing	both	Truth-routing metadata such as `areas.md` and `areas/*/.md`
`docs/standards/`	standard	agent	Reusable constraints, verification rules, completion gates
`docs/truthmark/product/`	product truth	agent	Product capability promises, boundaries, decisions, and acceptance criteria
`docs/truthmark/engineering/`	engineering truth	agent	Current implementation behavior for init, check, contracts, workflows, and operations
`docs/architecture/`	architecture	agent	Repository-specific architecture guardrails
`docs/research/`	research	human	Non-canonical research evidence, evaluations, and comparisons
`docs/truthmark/templates/`	template	both	Editable templates for scaffolded docs; templates are not Truth Sync targets
`docs/user-guide.md`	guide	human	Detailed usage guide kept out of the root README so onboarding stays concise

Frontmatter Policy

Canonical docs should include frontmatter and keep these fields current:

status
doc_type
last_reviewed
source_of_truth

Update Rules

When repository-wide agent policy changes, update docs/ai/repo-rules.md.
When code-to-doc routing changes, update docs/truthmark/routes/areas.md in the same change.
When package versions or release/version policy change, apply docs/standards/versioning.md before accepting the version.
When PR or release source text is needed, write a changes/ note using docs/standards/change-notes.md.
When truthmark init or scaffolded files change, update the relevant truth or architecture doc, not only README.md.
When truthmark check changes what it validates or how it reports diagnostics, update both the current truth doc and the contract doc.
When major product, onboarding, install, command, positioning, or workflow behavior changes, review the root README.md and update it if the human entry point would otherwise be stale.
Keep active docs current-state focused; promote necessary accepted rationale into the owning decision section and rely on Git history for superseded plans.
When current behavior changes for architecture, contracts, or lane-separated truth docs, update the owning current-behavior and Product Decisions or Engineering Decisions sections in the same change.
Do not keep parallel documentation trees for the same subject.

Important Truthmark-Specific Caveat

truthmark init is the only setup command. In a TTY it offers a numbered zero-or-more platform selection; repeatable --platform <id> values provide noninteractive selection, while --json never prompts. A first noninteractive run without platform flags remains host-neutral. Init creates or updates the version-2 .truthmark/config.yml, then writes a root route index plus one child route file under the configured routing root.

Maintenance Principle

The canonical tree should stay small, explicit, and current. Git history provides traceability for superseded context; active docs keep current behavior in the owning current-state section and accepted rationale in the owning decision section.

Product Decisions

Decision (2026-05-15): The docs index owns navigation and document-class guidance for the canonical tree, while docs/ai/repo-rules.md owns repository-wide authority order and completion policy.
Decision (2026-06-20): The root README is the concise human storefront. Detailed human-facing command, workflow, configuration, routing, Portal, and example material belongs in docs/user-guide.md.

Rationale

Keeping the docs index focused on navigation avoids loading duplicated authority prose while still giving agents and maintainers one stable place to resolve where current truth should live before they edit deeper canonical docs.

Keeping the root README concise reduces evaluator friction while preserving detailed operational guidance in a linked guide.
