Repository navigation
Ideon 1.0 makes the workspace trustworthy infrastructure: every project
carries a complete, tamper-evident record, and any state can be sealed,
exported, and verified independently — by anyone, without Ideon.
Added
- Added official records — seal a project state as an immutable, hash-chained reference and download the formal dossier as a ZIP archive.
- Added a Provenance action in the block context menu — right-click any block to see where it came from and what happened to it in the sealed record.
- Added a project audit trail — lifecycle changes, saved states, rewinds, and rejected write attempts are recorded as chained and tamper-evident events.
- Added database blocks — a spreadsheet-style block with columns, rows, sorting, filtering, and relation cells that link to other blocks (#126).
- Added a center anchor marker to sub-canvases so flows can be routed through the canvas center (#135).
- Added Git repository sync so canvas structure, positions, notes, and diagrams can be versioned and restored or synchronized safely (#125).
- Improved Markdown tables in canvas notes so comparison matrices remain readable and collaborative while editing (#121).
- Added Mermaid diagram blocks with collaborative source editing, canvas previews, and PNG export (#118).
Security
- Server-enforced access control on the versioning API — collaborators can no longer restore, rename, or delete project history regardless of client state; only the project owner can rewind, rename, or remove states.
Removed
- Removed SAML SSO support — enterprise sign-in via SAML identity providers is no longer included; external identity providers remain available through OAuth providers and generic OIDC.
Fixed
- Fixed login failures caused by Auth.js
UntrustedHosterrors (#133). - Atomic rewind — restoring a past state rewrites the project in a single transaction and propagates to every connected client, with a confirmation dialog that flags unsaved local changes before applying.
