* ♻️ Simplify storage GC delays and add skip-delay task params The touched GC no longer applies an extra deletion-delay when marking storage objects as deleted. By the time a storage object is touched, its referencing domain row has already passed its own deletion delay, and the reference scan is the only safety check needed. Touched objects are now marked with deleted_at = now, so the deleted GC removes them on the next run. For the tempfile bucket, upload chunks now set touched-at in the future (1h, aligned with the upload-session-gc TTL) instead of relying on a special-case deletion delay. Task handlers now read their task props: - storage-gc-touched accepts :skip-delay to process all touched objects immediately, bypassing the min-age threshold. - objects-gc accepts :chunk-size and :skip-delay to process recently deleted rows without waiting for the deletion delay. This allows running the deletion cascade immediately from the REPL via run-task! with the skip-delay option. AI-assisted-by: deepseek-v4-flash * ✨ Add storage object status lifecycle, verified dedup, and deletion retry tracking Storage object lifecycle hardening: - Add status column ('valid' | 'pending') as write-ahead marker for object creation. put-object! inserts in 'pending' state, writes blob, then promotes to 'valid'. Failed writes remove the pending row. - Add :storage-pending-gc task to reclaim orphaned pending rows (e.g. after crash between blob write and promotion). - Verify blob existence on every dedup hit via exists-object? (fs stat / s3 headObject). Missing blobs mark the row as deleted and create fresh object. - Add deletion_attempts column (migration 0154) to track physical blob deletion attempts. Restructure gc_deleted to use chunked processing with per-chunk transactions (short lock duration). Failed deletions are deferred to tomorrow (deleted_at = NOW() + 1 day) to prevent infinite loops. After 7 attempts, give up and accept orphan. - Change del-objects-in-bulk contract to return #{fail-ids} for precise per-id tracking (fs and s3 backends updated). - Use tmp/tempfile for fs atomic writes with cleanup queue registration (crashed-JVM temp files swept ~60min later). Document ATOMIC_MOVE POSIX-only assumption. - Add linear backoff to s3 exists-object? retries (100ms/200ms/300ms). - Wrap compensating delete in put-object! catch block to prevent masking original error when connection is aborted. - Fix assert messages in pending_gc.clj and gc_deleted.clj (pool assertion said 'expected valid storage' instead of 'db pool'). - Add pending-objects-excluded-from-gc-deleted test. Use unique path in put-object-write-failure-leaves-no-row test to avoid collisions.

Penpot is the open-source design platform for teams that build digital products at scale.
Penpot’s key strength lies in giving you full ownership of your design infrastructure. Built on open source and designed for self-hosting, it puts teams in complete control of their design environment supporting strict compliance and governance requirements. Whether used in the browser or deployed on your own servers, Penpot works with open standards like SVG, CSS, HTML, and JSON.
Real-time collaboration strengthens this foundation, helping teams scale and bring design closer to the product through top-tier capabilities. Additionally, developers feel at home using Penpot, because design is expressed as code, enabling a direct translation and shipping products faster.
Best-in-class native Design Tokens provide a single source of truth between design and development. They ensure consistency, improve collaboration, and make it easier to manage complex design systems.
The MCP server takes it further by enabling multi-directional workflows between design and code. A powerful open API and plugin system makes the workspace programmable, enabling automation, AI-driven workflows, and integrations with the tools and systems you already use.
With CSS Grid and Flex Layout, teams can design responsive interfaces that behave like real code from the start.
Combined, these features turn Penpot into a full-stack design platform for building scalable design systems and fully integrated product development processes.
If your organization is scaling and needs extra support, we’re here to help. Talk to us

Why Penpot
Penpot connects design, code, and AI workflows through a code-based approach, making designs readable by developers and AI via the MCP server. This approach helps teams ship what’s actually designed and manage design systems at scale with powerful design tokens. As a self-hosted, open-source and real-time collaboration platform, Penpot offers full flexibility, security, and ownership without vendor lock-in. Learn more about why Penpot is the platform for your team.
Plugin system
Penpot plugins let you expand the platform's capabilities, give you the flexibility to integrate it with other apps, and design custom solutions.
Designed for developers
Penpot was built to serve both designers and developers and create a fluid design-code process. You have the choice to enjoy real-time collaboration or play "solo".
Inspect mode
Work with ready-to-use code and make your workflow easy and fast. The inspect tab gives instant access to SVG, CSS and HTML code.
Integrations
Penpot offers integration into the development toolchain, thanks to its support for webhooks and an API accessible through access tokens.
Building Design Systems: design tokens, components and variants
Penpot brings design systems to code-minded teams: a single source of truth with native Design Tokens, Components, and Variants for scalable, reusable, and consistent UI across projects and platforms.
Getting started
Penpot is the only design & prototype platform that is deployment agnostic. You can use it in our SAAS or deploy it anywhere.
