EGC

Every decision, on the record.

An append-only governance ledger for AI-assisted development: see what was decided, who reviewed it, and what still stands.

Core governance available · Web multi-project access and licensing in development

The starting point

Too many records, no single answer

Decisions, changes and review notes pile up in long documents until nobody can say which conclusion is still current.

Many AI agents, no clear trail

When several coding assistants work in parallel, it's hard to reconstruct who changed what, why, and whether anyone checked it.

More projects, less visibility

Opening each project one by one is slow, and blockers or conflicting decisions slip through.

Core features

The governance ledger

  • Append-only event ledgerDecisions, changes and analyses are recorded as events; history is never rewritten—revisions supersede, they don't overwrite.Available
  • Lifecycle state machineEvents move from Draft to Logged, Implemented, In Review, then Approved or Changes Requested; invalid transitions are blocked.Available
  • Independent reviewsReviews are separate records, authors can't approve their own work, and every comment and follow-up stays traceable.Available
  • Current conclusionsFor each topic, see the conclusion that applies today—and the event it came from.Available
  • Automatic open itemsPending and missing reviews, requested changes, blockers, follow-ups and conflicts surface on their own.Available
  • Consistency checksValidates states, references and conflicts, reported as errors, warnings and notices.Available

Search and insight

  • Search, timeline and topicsFind and browse events by keyword, date, topic or author.Available
  • Milestone progressTracks completion against the milestones you define and shows where you are now.Available
  • Functional DNA (core)Extracts functional fingerprints from code so you can query them and compare variants.AvailableMedium+
  • Semantic searchFinds events by meaning, not just matching words, in Chinese and English.Preview
  • Relationship graph and impactShows how events reference, supersede and block each other, including knock-on effects.Preview
  • Governance suggestionsProposes fixes based on ledger health as reviewable drafts, with dry runs and rollback.PreviewMedium+

Access and multi-project

  • AI assistant access via MCPCoding assistants query and log events over the standard MCP protocol; every write is authenticated and audited.Available
  • Command-line toolEvery capability is scriptable, with stable JSON output that drops into your pipelines.Available
  • Web workspaceReview events, reviews, open items, timelines, milestones and risks in the browser, with a guided event wizard—no command line needed.Available
  • Multi-project hub (for developers)Pulls several project ledgers into one local hub for cross-project search, topics and conflicts; rebuildable anytime and never writes back.Available
  • Web multi-project workspaceSwitch between projects on one page, each with its own events, reviews and open items, fully isolated.In development
  • Web portfolio dashboardOne view of risks, open items and review progress across all projects.In development

Security, release and licensing

  • Tamper detectionRecords are chained by hash, so any alteration is detected.Available
  • Backup and restoreOne-step snapshots with checksums, verifiable and restorable; an older backup can't overwrite a newer ledger by default.Available
  • Local-first securityThe web app listens only on your machine by default; remote access requires explicit admin authentication, and misconfiguration stops startup.Available
  • Release readiness and reportsBefore release, lists unclosed reviews and blockers and exports governance reports as CSV or Markdown.PreviewMedium+
  • Encrypted ledgersOptionally encrypt project ledgers, with keys kept apart from data.Preview
  • Plan licensing and activationPer-machine licensing: activate your plan locally after purchase, with a limited offline grace period.In development

What sets it apart

Append-only facts, traceable answers

Nothing is edited or deleted; new events supersede old ones, every current conclusion points to its source, and a hash chain exposes tampering.

Doing and reviewing stay separate

Reviews are their own records, no one approves their own work, and anything awaiting review or changes lands on the open-items list automatically.

One ledger, three ways in

The command line for developers and automation, MCP for AI coding assistants, and a web workspace for business, audit and management teams.

Use cases

Multi-agent development

Who: Engineering leads running several AI coding assistants at once. Situation: Assistants change code in parallel, and afterwards no one can say who did what, why, or whether it was checked. How: Assistants connect via MCP, log an event before starting, mark it Implemented when done, and a different identity reviews it. Outcome: Every change carries a record, a rationale and an independent verdict; anything unreviewed, sent back or blocked shows up as an open item.

Multi-project oversight

Who: Project owners and engineering directors responsible for several projects. Situation: Each project has its own ledger; opening them one by one is slow and risks are hard to compare. How: Register each ledger with the multi-project hub to search topics, open items and conflicting decisions in one place (available through developer tools today; the web dashboard is in development). Outcome: One place to see the whole portfolio and spot stalled projects and contradictory decisions fast.

Pre-release audit

Who: Quality and release managers, internal and external auditors. Situation: Before a release or handover, you must confirm every key change was reviewed—and be able to prove it. How: Check unclosed reviews, blockers and conflicts, verify ledger integrity, and export a governance report (report export is in preview). Outcome: Audit material traceable to every source event, with any tampering detected.

Architecture

Every entry point writes through one authenticated path and rule checks into the ledger; the hash chain and indexes feed derived views back to each entry point, and ledgers sync read-only into the multi-project hub.

Workflow

From logging to independent review. Preview features may change before general release; dates for in-development features will be announced separately. EGC provides traceable audit evidence; it does not constitute any compliance certification.

  1. Check status

    Before starting, check validation results, open items, recent events and milestone progress.

  2. Log a draft

    Log a draft event for the change.

  3. Work and record

    Append progress as you go, then mark it Implemented.

  4. Independent review

    A reviewer other than the author approves or requests changes; requested changes are fixed and resubmitted.

  5. Update conclusions

    Once approved, current conclusions and milestone progress update automatically.

  6. Supersede

    When a new decision arrives, a new event supersedes the old one and the full history stays intact.

How EGC works with execution tools

Arrows show only the provenance of registrations, review records and derived views; they do not mean that EGC executes work or grants approval automatically.

  1. Executors (chosen by you)

    • AI coding assistants (via MCP)
    • Scripts / automation pipelines (via CLI)
    • People (via the Web workspace)Available
  2. EGC: records and reviews

    • Append-only ledger
    • Independent review records (reviewer ≠ author)
    • Current conclusions / open items / mainline progress
  3. Back to your chosen executors

    • Evidence for deciding whether the next step may proceed
  1. What EGC does

    Records every change, decision and review as append-only, traceable events, deriving views of “what applies now, what remains to be done, and who reviewed it”.

  2. What EGC does not do

    EGC does not execute code for you, schedule AI tasks, or replace people in making the final confirmation. Your chosen tools or team decide who does the work; EGC records what happened clearly and keeps reviews independent.

  3. How to work together

    AI coding assistants connect via MCP, scripts via the command line, and people view and review through the Web workspace (the multi-project workspace is in preview); all three entry points write to the same ledger and follow the same rules.

  4. When you need execution control

    If your team needs execution controls such as “only one executor at a time” or “human confirmation required at key steps”, you can use EGC alongside Lanruan’s EGC Supervisor (see its product page for the status and public description of EGC Supervisor).
