Review Workbench, Multi-Forge PR Review (GitLab, Gitea, Bitbucket), AI Merge & Conflict Resolution, Intra-Line Diff Highlighting, and Interactive Tips

Introduces the Review Workbench for opening directories and PR worktrees from a single dashboard, expands pull request review to GitLab, Gitea/Forgejo, and Bitbucket Cloud with in-app token onboarding, adds PR merge controls with AI conflict resolution and commit message rewriting, delivers sub-character intra-line Myers diff highlighting with insertion carets, embeds an interactive tips and tricks system, and streamlines agent-assisted rebase and merge synchronization.

// Review Workbench

  • Launch a unified workbench dashboard by running bare px0 without arguments to open any directory, browse the local filesystem, or paste PR review URLs
  • Fast interactive path autocompletion: type paths with instant folder suggestions, git repository indicators, Tab completion, and arrow-key navigation
  • Manage recent and pinned workspaces with persistent storage in workbench.json, running status dots, one-click reopening, and Cmd/Ctrl-click multi-tab support
  • Worktree-based PR checkouts: automatically locate and reuse existing local repository clones or create managed partial clones in ~/.px0/repos without duplicating history
  • Aggregate status bar metrics: CPU, RAM, and LSP memory chip sums the workbench and active child processes with an interactive per-process breakdown
  • Single-instance activation: running px0 while a workbench is active pings and focuses the existing instance, with automatic idle workspace shutdown after 30 minutes of inactivity

// Multi-Forge PR Review (GitLab, Gitea, Bitbucket)

  • First-class GitLab support: review merge requests on gitlab.com and self-hosted instances with nested group paths, token discovery (gitlab.token, GITLAB_TOKEN, glab CLI), and scoped HTTP git transport
  • Gitea, Forgejo, and Codeberg support: review PRs, inspect diffs, draft inline comments, and execute reviews with gitea.token or GITEA_TOKEN
  • Bitbucket Cloud support: review pull requests across workspace repositories with API tokens, branch checkouts, and native thread replies
  • In-app Forge Connect modal: guided token setup with direct links to forge token generation pages, instant permission verification, and dynamic configuration without server restarts
  • Stable PR draft persistence: review comment drafts are keyed to stable PR identifiers in $XDG_STATE_HOME/px0/pr-sessions/, preserving drafts across reopens and worktree recreations

// PR Merge Controls & AI Conflict Resolution

  • Real-time mergeability status: live status pill in the PR bar displays clean, conflict, behind, or blocked states according to remote forge rules
  • Configurable merge execution: split button supporting Create a merge commit, Squash and merge, or Rebase and merge matching repository policies
  • Interactive merge dialog: review and customize merge commits with AI-assisted title and body rewriting powered by your local coding harness
  • Agent-assisted conflict resolution: automatically dispatch coding harnesses to resolve base-branch divergence via Rebase with AI or Merge with AI
  • Safe lease force-pushing: after AI rebase, push rewritten PR review branches using force-with-lease to protect concurrent upstream commits

// Intra-Line Character Diff Highlighting

  • Token-level Myers diff algorithm with sub-character refinement to pinpoint exact character additions, modifications, and deletions within changed lines
  • Insertion caret indicators on unmodified counterpart lines to clearly visualize insertion positions
  • Consistent highlighting across both Side-by-Side (Split) and Inline (Unified) diff layouts with opacities matched to active theme CSS variables

// Interactive Tips & Tricks System

  • Non-intrusive floating tip widget that appears after startup with previous/next navigation and automatic progression
  • Searchable and filterable Tips tab in the right-side inspector panel to discover shortcuts, Git workflows, and hidden capabilities
  • Sidebar footer help button (?) and Command Palette actions (Help: Tips & Tricks, Help: Show Tip) for on-demand access
  • Public tip delivery cached from px0.ai with offline fallback definitions and permanent dismissal toggle via tips.enabled

// Git Panel & Agent-Assisted Sync

  • Divergence handling on pull: when branches diverge, px0 refuses conflicting fast-forwards and offers Rebase with AI or Merge with AI via the local harness
  • In-panel error cards: all Git operations (stage, commit, push, pull, abort) display diagnostic details in an inline card within the Git panel rather than noisy global toasts
  • Live sync progress streaming: track harness output during rebase or merge operations with 1-click abort to restore clean branch state

// Editor, UI & State Management

  • Preserve scroll position, editor line offset, and preview state when toggling between edit and view modes for Markdown, CSV, and TSV files
  • Visual copy feedback: code block copy buttons temporarily toggle to a checkmark icon on click
  • File tree starts collapsed by default on startup for a distraction-free view, suppressing auto-reveal until files are explicitly opened
  • Clean server shutdown: register shutdown hooks to drain in-flight event streams and terminate active SSE listeners cleanly

// Documentation

  • Add comprehensive guides for the Review Workbench, multi-forge pull request workflows, and the interactive tips system
  • Update Git integration guides with agent-assisted pull sync, merge controls, and intra-line diff highlighting
  • Document new configuration options for GitLab, Gitea, Bitbucket, and tips preferences in settings reference

On-Demand Vendor Asset Caching, Ultra-Lean Binary Footprint, Frontend Minification & Double-Gzip Fix

Unbundles heavy vendor assets from the Go binary in favor of transparent on-demand CDN fetching and persistent local caching, introduces frontend bundle minification, resolves static asset double-compression, improves Mermaid export resolution, and streamlines native executable distribution.

// Binary Footprint & On-Demand Vendor Caching

  • Unbundle the bulky Mermaid diagram runtime from binary embedding, significantly slashing executable size while keeping memory usage minimal
  • Intelligent on-demand vendor caching: automatically downloads pinned Mermaid releases from CDN on first diagram render and stores them in ~/.px0/cache/vendor/
  • Serve cached vendor assets strictly from the same origin (/static/vendor/mermaid-12.0.0.min.js), preserving strict Content Security Policy ('self') and offline capabilities after initial fetch
  • Maintain native unpacked executable distribution to eliminate antivirus false positives and preserve OS read-only memory page sharing

// Performance & Build Optimizations

  • Minify the frontend client bundle using Bun (--minify), reducing uncompressed client JavaScript from ~448 KB down to ~250 KB
  • Add gzip bypass mechanism in static file handlers to prevent double gzip compression regressions on precompressed assets
  • Improve global export resolution in the Mermaid runtime loader for consistent diagram rendering across browser environments
  • Add cache-busting version identifiers to vendored Mermaid asset bundle requests to ensure reliable updates

// Cleanup & Testing

  • Remove obsolete re-exec helper routines (update_unix.go, update_windows.go) following the non-disruptive update notification model
  • Add unit test coverage for double-gzip bypass and update integration test harnesses

Pre-Compressed Static Assets, Transparent Decompression Fallback & HTTP Cache Headers

Implements automated build-time gzip pre-compression for vendor JavaScript assets, transparent server-side decompression fallbacks for non-gzip clients, long-lived HTTP cache control headers, and comprehensive static asset unit tests.

// Static Asset Compression & Delivery

  • Pre-compress vendor JavaScript assets using gzip level 9 during the web build process to minimize network payloads
  • Transparently serve pre-compressed assets with Content-Encoding: gzip and Vary: Accept-Encoding headers when supported by the client
  • Dynamic decompression fallback serves uncompressed payloads to legacy clients that do not negotiate gzip compression
  • Set immutable cache control headers (Cache-Control: public, max-age=31536000, immutable) and accurate MIME content types for static vendor responses
  • Add unit test assertions verifying static asset serving, compression negotiation, and transparent decompression fallbacks
