Closes #1470
Stacked on #1465 (Wave 0 refactor — must merge first)

Summary

Replaces the cramped RL:5h:13%,7d:96% badge with a visually-scannable severity-icon rendering:

RL:5h░13% 7d▓96%

Design

  • light (U+2591): pct ≤ 60 (healthy / green intent)
  • medium (U+2592): 60 < pct ≤ 85 (warning / yellow intent)
  • dark (U+2593): pct > 85 (critical / red intent)
  • Space separator replaces comma (easier to miss)
  • RL: prefix preserved so downstream surfaces keep a stable anchor

Defensive coercion

New _coerce_percentage() helper silently turns None, non-numeric strings, and unexpected types into 0.0. Prevents the TypeError footgun identified by Wave 1-A security review (A03 low finding: if Claude Code stdin ever sends {"used_percentage": "N/A"}, the hot-path f-string formatting would crash the entire statusLine).

Tests

162/162 pass

19 new tests in test_hud_rate_limits.py:

  • All 3 severity buckets
  • Boundary checks (60 inclusive → low, 85 inclusive → medium, 85.01 → high)
  • Both-tier rendering with mixed severity
  • Defensive coercion: None, "N/A", numeric string, missing key
  • Space-separator assertion (assert "," not in result)
  • Re-export identity lock from codingbuddy-hud
  • _severity_icon helper exposure

3 test_hud.py tests updated to new visual format (scoped minimal edit of Wave 3's normally-owned file — justified by Wave 1-C's inherent visual format change).

Replaces `RL:5h:13%,7d:96%` with `RL:5h░13% 7d▓96%`:
- Severity icons (░ ▒ ▓) visually distinguish low/medium/high usage
- Space separator replaces comma
- `RL:` prefix preserved for downstream anchors

Also adds defensive float coercion to _coerce_percentage() so a
non-numeric used_percentage (None, "N/A") is silently treated as
0.0 instead of crashing the statusLine hot path — addresses Wave
1-A security reviewer's A03 low-severity finding.

19 new tests in test_hud_rate_limits.py cover all 3 severity
buckets, boundary values (60, 85, 85.01), both-tier mixed severity,
defensive coercion (None, string, numeric string, empty tier), and
re-export identity from codingbuddy-hud.

3 test_hud.py tests updated to new visual format.

162/162 tests pass.

Combined Wave 0 polish items from the #1465/#1485 review cycle:

1. Narrow `except Exception` to `except ImportError` in the 3 lib
   fallback import blocks (qual-1465 HIGH-1). Real logic bugs
   (SyntaxError, NameError, AttributeError) inside lib modules now
   surface immediately instead of being silently swallowed by a
   catch-all.

2. Drop inline stub functions for format_rate_limits and
   _get_fresh_version (qual-1465 HIGH-2). Eliminates the signature
   drift between canonical lib definitions and in-file fallback stubs
   observed on the integrator branch (Wave 1-A plugin_json_file
   kwarg drift). The outer main() try/except still catches any runtime
   failure and emits the minimal safe output via the BUDDY_FACE
   constant.

3. Hoist hud_velocity and hud_cache_savings imports to module top as
   _format_velocity_segment and _format_cache_savings (perf-1485 H1).
   Eliminates ~0.47us sys.modules lookup per render. Integrator branch
   only - no-op on refactor/wave branches where the inline imports
   don't exist yet.

4. Bump next to 16.2.3 for GHSA-q4gf-8mx6-v5v3 (landing-security-check).
   Aligns eslint-config-next and updates setup.test.ts assertion.

Superseded by #1485

This PR was part of a stacked PR structure (feat/statusbar-wow-refactor base) that was incompatible with the repo's rebase & merge policy — each sub-PR targeted an intermediate branch, not master.

All of this PR's commits have been consolidated into #1485 (now with base: master and a linear 12-commit history after rebase). The consolidated PR contains:

  • Wave 0 — de622cc refactor(hud): extract 9 modules
  • Wave 1-A — cdf0772 fix(hud): version resolution fallback
  • Wave 1-B — 0606698 fix(hud): session self-heal
  • Wave 1-C — 87b779a feat(hud): rate limit severity icons
  • Wave 1-D — 894f515 feat(hud): adaptive layout engine
  • Wave 2-A — 5e8389d feat(hud): breathing buddy face states
  • Wave 2-B — 78ec6c5 feat(hud): cost velocity indicator
  • Wave 2-C — a306920 feat(hud): cache savings badge
  • Wave 2-D — 0fb3d5c feat(hud): mode rainbow ANSI coloring
  • Wave 2-E — 8cd78b2 feat(hud): smart context bar
  • Wave 3 — 295f5c4 feat(hud): integrate Wave 2-B/2-C
  • Review iter1 — b330528 fix(hud,landing): narrow fallback imports + next 16.2.3

EVAL review results from this PR (all reviewers, iter1 converged → Critical=0, High=0) already applied in #1485.

Closing as superseded. Use #1485 with GitHub's Rebase and merge button to land all 12 commits linearly on master.
