DECISIONHuman review

LedgerInfra keeps and serves artifact context. It does not make the decision.

THE EVIDENCE LOOP

The task ends. The evidence should not.

Keep the exact published HTML people reviewed and its source URL available so a later task can start from verifiable context—not guesswork.

01
AUTHORIZED SOURCE
Start from one permission-checked Workspace.
The source stays inside the authorized Workspace, with a chunk and fixed URL that can be checked again.
AUTHORIZED CHUNK + FIXED URL
02
AI-GENERATED ARTIFACT
Create one self-contained HTML file.
Codex, Claude Code, or another authorized tool creates the artifact. LedgerInfra keeps the published file intact.
SELF-CONTAINED HTML
03
HUMAN DECISION
People review the latest URL and decide.
LedgerInfra records the context behind a decision; it does not approve, schedule, or run the loop.
HUMAN REVIEW
04
FIXED VERSION
Keep the exact HTML behind the decision.
The fixed version URL stays available for the artifact people reviewed, even as the latest URL moves on.
FIXED VERSION URL
05
NEXT AUTHORIZED TASK
Return relevant context when work resumes.
Search can return the relevant authorized chunk and fixed source URL so the next task starts with evidence, not guesswork.
SEARCH RESULT

OWNERSHIP, MADE VISIBLE

Clear boundaries. Clear responsibility.

Git — code

Source of truth for code and docs.

CI — verification

Builds, tests, and verifies changes.

Orchestrator — execution state

Tracks tasks, runs, and their state.

LedgerInfra — reviewed artifact + source context

Stores reviewed artifacts, links to source, and enables retrieval.

LedgerInfra carries artifact context. It does not schedule, execute, test, merge, deploy, or approve the loop.

RETRIEVAL FOR AGENTS

Find the source. Follow what it points to.

Search is the entry point. Graph continues from a known version. Both stay inside one authorized Workspace and return fixed source URLs.

Find relevant chunks inside published HTML.

FREE · PRO · TEAM · BUSINESS

Hybrid retrieval finds permission-checked source chunks in one Workspace. Every result identifies the Slide, version, and fixed URL.

Trace explicit references and version lineage.

PRO · TEAM · BUSINESS

Start from a Slide or Search query. Graph returns a one-hop view of explicit LedgerInfra links and optional previous or next versions of the same Slide.

ONE PUBLISHING LOOP

Keep the work visible, versioned, and retrievable.

SELF-CONTAINED HTML

Keep the artifact your agent actually made.

Publish one self-contained HTML file with its CSS, JavaScript, images, diagrams, and interactions intact. LedgerInfra does not convert it into a template or proprietary format.

LATEST + FIXED VERSIONS

Update the work without breaking the conversation.

Keep one latest URL in the review thread. Use a fixed version URL when a decision, handoff, or agent citation must point to the exact HTML that was seen.

latest URL + /v/{version_key}

SEARCH RETRIEVAL

Let agents find the source chunk, not just a filename.

Search retrieves authorized chunks from published HTML inside one Workspace and returns the fixed source version for human verification.

GRAPH RETRIEVAL

Follow the references already present in the work.

Graph explores one hop of explicit LedgerInfra links and, when requested, the previous or next version in the same Slide lineage.

ORGANIZATION CONTEXT

Keep the Workspace boundary clear.

Every login starts with an Organization and a default Workspace. Free and Pro keep a clear owner/editor boundary with viewer sharing; Team and Business add the shared Editor-capacity pool. Membership, roles, and visibility control what people and agents can access.

FAQ

What to know before you publish.

Is LedgerInfra an AI presentation maker?

No. Codex, Claude Code, or another tool creates the self-contained HTML. LedgerInfra publishes, versions, authorizes, and retrieves the finished artifact.

What can I publish?

The current input is one self-contained HTML file up to 20 MB with no external asset dependencies. Slide decks are the primary use case; reports and interactive demos work under the same input contract.

What does Search return?

Search returns authorized HTML chunks, ranking information, Slide and version identifiers, and a fixed version URL. LedgerInfra does not generate an answer from those results.

What does Graph return today?

On Pro, Team, and Business, Graph returns a one-hop view of explicit LedgerInfra references and optional same-Slide version lineage. Every node points to a fixed version.

What is the difference between latest and fixed URLs?

The latest URL follows the newest version under the same slug. A fixed version URL never changes, so it can anchor a review, decision, handoff, or retrieval result.

Who can view and retrieve Workspace HTML?

Workspace membership and artifact visibility are evaluated before content is returned. Public, Workspace-only, and private visibility have different access boundaries; knowing a URL does not grant access.

Are Pro and Team successive upgrade tiers?

Yes. Free, Pro, Team, and Business are one Organization plan ladder. Free and Pro keep one owner/editor boundary with viewer sharing; Team and Business add the existing Organization member and Editor-capacity model. Business Checkout remains coming soon.

What is included on Free?

Free costs ¥0, requires no card, and includes 25 active Slides, up to 20 versions per Slide, 1 GB of version storage, and Search. Graph is available on Pro, Team, and Business.
