- **added** — Google's Antigravity (agy CLI) is now a fully supported built-in agent that runs through the ACP chat surface
- **added** — Message anchor rail along the left edge of the chat area shows one tick per user message with hover preview and click-to-jump functionality
- **added** — Magnifier at the head of the message anchor rail provides a second, more visible entry point for conversation search
- **added** — Right-click any file in the Explorer to reveal it in your system file manager (desktop only)
- **fixed** — A slow backend startup is no longer misreported as a broken installation
- **fixed** — On systems where the OS file-watch quota is exhausted, the backend now degrades gracefully instead of failing to start
- **fixed** — Install-integrity failures that have already self-healed are reconciled before alerting
- **fixed** — Manual check for updates now treats the CDN channel manifest as authoritative so the check works when the GitHub API is unreachable
- **fixed** — Opening files from the Explorer restores multi-tab behavior in the preview panel instead of replacing the current tab
- **fixed** — A CLI agent's first turn no longer incorrectly uses the aionrs provider model
- **added** — Antigravity (agy CLI) added as a direct-CLI agent in AionCore
- **added** — Workflows, background Bash commands, and background Task subagents now stream live progress cards and deliver results out-of-turn
- **fixed** — A cancel that arrives while the agent is still building its turn is now applied instead of being dropped
- **fixed** — Tool subprocesses that escape their process group are now reaped and transient failures activating the bundled Node runtime are retried
- **fixed** — Windows path outputs no longer leak the verbatim \\?\ prefix
- **fixed** — Database migration pre-repair now covers any pre-030 starting point to prevent startup-blocking upgrades

##### Highlights

###### Antigravity Support

- Google's Antigravity (`agy` CLI) is now a fully supported built-in agent. Previously it could be selected but did nothing — no chat surface appeared and the first message was never delivered. It now runs through the ACP chat surface like any other agent.

###### Message Anchor Rail

- Long conversations get a message anchor rail along the left edge of the chat area: one tick per user message, hover to preview that turn, click to jump straight to it. A magnifier at the head of the rail gives conversation search a second, more visible entry point.

###### Explorer Reveal in Folder

- Right-click any file in the Explorer to reveal it in your system file manager (desktop only).

###### Startup & Update Reliability

- A slow backend startup is no longer misreported as a broken installation. Previously a health-check timeout could pop a blocking "reinstall / check your antivirus" dialog even though the backend was alive and listening — misleading advice for a problem reinstalling could not fix.
- On systems where the OS file-watch quota is exhausted (common on ARM Linux), the backend now degrades gracefully instead of failing to start, and the UI no longer blames an incomplete installation.
- Install-integrity failures that have already self-healed are reconciled before alerting, so you don't get warned about a problem that no longer exists.
- Manual "check for updates" now treats the CDN channel manifest as authoritative, so the check still works when the GitHub API is unreachable.

###### Fixes & Improvements

- Opening files from the Explorer restores multi-tab behavior in the preview panel instead of replacing the current tab.
- A CLI agent's first turn no longer incorrectly uses the aionrs provider model.

###### Engine updates (AionCore v0.1.56 → v0.1.57)

- Antigravity (`agy` CLI) added as a direct-CLI agent — the backend half of the support above.
- **Background work is now visible.** Workflows, background Bash commands, and background Task subagents used to leave a Claude conversation completely silent — a 17-minute workflow showed nothing for its entire flight. They now stream live progress cards, and results are delivered out-of-turn instead of triggering an unprompted turn.
- A cancel that arrives while the agent is still building its turn is now applied instead of being dropped.
- Tool subprocesses that escape their process group are now reaped, and transient failures activating the bundled Node runtime are retried instead of surfacing as hard errors.
- Windows path outputs no longer leak the verbatim `\\?\` prefix.
- Database migration pre-repair now covers any pre-030 starting point, widening protection against startup-blocking upgrades.
