feat(hud): complete Wave 3 integration for 1-D/2-A/2-D/2-E (Wave 3b)#1488
Merged
Conversation
Commit bd78195 ("integrate Wave 2-B/2-C in format_status_line") wired velocity and cache-savings into the cost segment but left four sibling Wave modules as dead code: hud_buddy, hud_rainbow, hud_context_bar, and hud_layout. Their unit tests passed, but format_status_line never called them — the statusLine rendered with a static buddy face, no adaptive layout, text-only context percentage, and no mode coloring. This commit closes that gap by hoisting all four modules as top-level imports (matching the velocity/cache_savings pattern) and refactoring format_status_line to build (name, priority, text) segments consumed by fit_segments. Wave 2-A — breathing buddy face BUDDY_FACE constant → select_face_from_state(hud_state). The face now reflects phase/blockerCount: ready/None → ◕‿◕ (idle) planning/evaluating → ◔‿◔ (thinking) executing/cycling → ◕◡◕ (active) blockerCount > 0 → ◕︵◕ (error, wins over phase) lastEvent=victory → ◕ᴗ◕ (victory, wins over phase) Wave 2-D — mode rainbow ANSI coloring (opt-in) Gated on CODINGBUDDY_HUD_RAINBOW=1 because Claude Code statusLine's ANSI support is environment-dependent; default OFF keeps existing terminals clean. Transitively honours NO_COLOR (https://no-color.org) via hud_rainbow.is_color_enabled. Only real modes (PLAN/ACT/EVAL/AUTO) are colored — the "Ready" fallback label stays plain so tests and logs don't see it uppercased. Coloring is applied POST-fit_segments (string replace on the already-assembled line1) so the ANSI escapes don't break hud_layout.visible_len width accounting during layout. Wave 2-E — smart context bar "Ctx:{pct}%" segment → format_context_bar_segment(stdin_data), rendering e.g. "[████░░░░░░] 42%" or "[████████▓░] 92%⚠" above the warning threshold. Legacy "Ctx:" prefix is gone; the three existing tests asserting "Ctx:45%"/"Ctx:10%" have been updated to check for the new bar + percentage combination. Wave 1-D — adaptive layout Final " | ".join(segments) → fit_segments(layout_segments, terminal_width()). Low-priority segments (worktree, rate_limits, model, cache, ctx) are dropped first on narrow terminals; face_version and mode_health are sacred and always render. shorten_model_label trims the "(1M context)" suffix so Opus display names fit mid-width terminals without being dropped. test_full_telemetry gained monkeypatch.setenv("COLUMNS", "300") because its "all segments render" assertion would otherwise flake against the pytest 80-col default now that adaptive layout actually runs. Test coverage: - 14 new tests split across four classes: TestWave2ABreathingFaceIntegration (4) TestWave2EContextBarIntegration (3) TestWave2DRainbowIntegration (4) TestWave1DAdaptiveLayoutIntegration (3) - 3 existing tests updated to match the Wave 2-E "[bar] 45%" format - 1 existing test (test_full_telemetry) hardened with COLUMNS=300 Local runs: 1077 passed (full plugin test suite).

Bump the workspace version from 5.6.0 to 5.6.1 and publish the CHANGELOG entry for the HUD hotfix cycle. v5.6.1 is a hotfix closing the remaining gaps in the v5.6.0 HUD Statusbar Wave cycle: - Wave 1-B heal timestamp leak (#1487) — heal_stale_state preserved sessionStartTimestamp for "audit / forensics", but resolve_duration read the same field as a fallback when stdin lacked total_duration_ms. A manual-fix marker + stale timestamp therefore rendered enormous durations like 322h52m for brand-new sessions. The timestamp is now relocated into _healedFromSessionStartTimestamp. - Wave 3b — complete Wave 3 integration (#1488) — commit bd78195 wired Wave 2-B velocity and 2-C cache savings into format_status_line but left four sibling Wave modules as dead code: hud_buddy, hud_rainbow, hud_context_bar, and hud_layout. Their unit tests passed, but format_status_line never called them. v5.6.1 hoists all four as top-level imports and refactors format_status_line to build (name, priority, text) segments consumed by fit_segments, finally delivering the Wave 2-A breathing face, Wave 2-D rainbow coloring (opt-in via CODINGBUDDY_HUD_RAINBOW=1), Wave 2-E smart context bar, and Wave 1-D adaptive layout features that v5.6.0 advertised. Bump surface: - apps/mcp-server/package.json, src/shared/version.ts - packages/rules/package.json - packages/claude-code-plugin/package.json (+ peerDependencies), .claude-plugin/plugin.json, README.md, namespace-manifest.json - .claude-plugin/marketplace.json - yarn.lock - CHANGELOG.md (new [5.6.1] section)
