Simon FrankenandClaude Opus 5.5 2212b24fe1 Add submarine TUI prototype with mock data
Bubble Tea prototype for browsing repositories with many nested git
submodules: collapsible tree, pins shown as ref + distance, summarized
issue words with severity levels, detail pane, async loading via a
Provider interface backed by mock data. Includes docs/ with
requirements, state model, UX guide, architecture and decision log,
plus AGENTS.md.

submarine: a Go + Bubble Tea TUI for repositories with many git submodules. Currently a prototype on mock data.

Read first

The docs/ folder is the source of truth for requirements, state rules, UX and decisions. Read the relevant document before changing behavior:

Commands

go run ./cmd/submarine        # run (mock data)
go vet ./...
go test ./...
gofmt -l .                    # must print nothing

Rules

  • Keep docs in sync. A change to behavior, keys, colors, wording or architecture updates the matching document in docs/. A new significant decision gets an entry in docs/decisions.md.
  • Layering. internal/submodule has no UI imports and decides what a state means (Status.Issues()). internal/tui/theme decides how it looks. Components never classify states or define colors themselves.
  • Data access only through submodule.Provider.
  • Colors only from theme.Theme, ANSI 16 colors for meaning (see docs/ux-guide.md#colors). Render segments on a background with a base style (LevelStyle(level, base), Delta(pin, base)).
  • Tree navigation stays in plain methods on tree.Model with unit tests in internal/tui/tree/tree_test.go.
  • Verify UI changes by running the app, e.g. headless in tmux (see docs/architecture.md#testing), not only by tests.
