Description

Migrate Calendar and Clock widgets from built-in code to external WASM plugins.

Development Tasks (☿ Nova)

  • Create plugins/calendar/ with separate Cargo.toml
  • Port calendar logic to compile to wasm32-wasi target
  • Update core loader: reads calendar.wasm from ~/.config/bastion/plugins/
  • Same port process for clock widget
  • Remove built-in widget code from src/widgets/ (core shrinks)

Testing Criteria (☿ Nova)

  • Plugin load test: calendar.wasm -> running widget in pane
  • Plugin unload: widget gracefully removes from pane layout
  • Hot reload: file change in plugins/ triggers reload (dev mode)
  • Binary size test: core binary is smaller post-refactor
  • Distribution test: cargo xtask install-plugins sets up ~/.config

Completion Criteria (🜔 Claudian Review)

  • End-to-end: fresh install -> bastion -> plugins auto-build/setup
  • Performance: no frame time regression vs built-in implementation
  • Backward compatible: existing user configs work without migration
  • Documented: docs/MIGRATION.md for users and plugin developers

Blockers

  • #1 (Calendar Widget) - must exist to port
  • #2 (Clock Widget) - must exist to port
  • #6 (Plugin Trait Contracts) - interface must be stable
