The ID column was sized to the widest ID on screen, so a new commit that
lengthened one ID reflowed every subject and hash in the tree. It is a fixed
four-column field plus one space now: three-letter IDs keep two spaces, hex IDs
three, and an ID that outgrows the field — five letters, or a numeric-suffix
fallback — keeps its single space and shifts only its own line.

The abbreviated hash moves after the subject, where it stays out of the way of
the ID that names the commit for every loom command. The TUI drops it entirely
and shares graph::id_pad, so the two renderers can no longer disagree about
the column; IdAllocator::commit_id_width is gone with it.

Specs 001, 002 and 020, the status and tui pages, the guides, and the
integration helper that reads an ID out of status follow the new layout.

Summary by CodeRabbit

  • User Interface

    • Commit displays now show persistent short IDs before the commit message and abbreviated hash.
    • Short IDs use a consistent four-column layout, while longer IDs expand only their own lines.
    • TUI commit rows show short IDs without redundant abbreviated hashes.
    • Commit messages and hashes are aligned more consistently across status and graph views.
  • Documentation

    • Updated status output, tutorials, guides, and specifications to reflect the revised commit formatting, ordering, alignment, and TUI presentation.

📝 Walkthrough

Walkthrough

The change standardizes commit output. Graph lines use a fixed short-ID column, place subjects before hashes, and support oversized IDs. TUI rows omit hashes. Tests, specifications, integration helpers, and documentation use the updated format.

Changes

Commit display format

Layer / File(s) Summary
Rendering contract and graph implementation
specs/001-status.md, specs/002-shortid.md, src/core/graph.rs, src/core/shortid.rs
Commit lines place the subject before the abbreviated hash. Graph rendering uses a fixed four-column ID slot, and oversized IDs widen only their own lines.
TUI commit row rendering
specs/020-tui.md, src/tui/app.rs, src/tui/status_tree.rs
TUI commit rows use shared ID padding and no longer store or display abbreviated hashes.
Rendering and integration validation
src/core/graph_test.rs, src/core/shortid_test.rs, src/tui/app_test.rs, tests/integration/helpers.sh
Tests and status parsing validate the revised field order, alignment, TUI output, and short-ID extraction.
Specifications and documentation examples
docs/src/commands/*, docs/src/guides/*, specs/001-status.md, specs/020-tui.md
Status, guide, and TUI examples use the updated commit ordering and hash display rules.

A non-default Git abbreviation setting can make the branch-target integration workflow fail to find a commit ID, but the impact is limited to that test workflow.
