- measure status bar display width using prompt_toolkit cell widths
- trim rendered status text when fragments would overflow
- add a final single-fragment fallback to prevent wrapping
- update width assertions to validate display cells instead of len()
shutil.get_terminal_size() can return stale/fallback values on SSH that
differ from prompt_toolkit's actual terminal width. Fragments built for
the wrong width overflow and wrap onto a second line (wrap_lines=True
default), appearing as progressively degrading duplicates.
- Read width from get_app().output.get_size().columns when inside a
prompt_toolkit TUI, falling back to shutil outside TUI context
- Add wrap_lines=False on the status bar Window as belt-and-suspenders
guard against any future width mismatch
Closes#3130

The persistent status bar now shows context %, token counts, and
duration but NOT $ cost by default. Cost display is opt-in via:
display:
show_cost: true
in config.yaml, or: hermes config set display.show_cost true
The /usage command still shows full cost breakdown since the user
explicitly asked for it — this only affects the always-visible bar.
Status bar without cost:
⚕ claude-sonnet-4 │ 12K/200K │ 6% │ 15m
Status bar with show_cost: true:
⚕ claude-sonnet-4 │ 12K/200K │ 6% │ $0.06 │ 15m
Salvaged from PR #1104 by kshitijk4poor. Closes#683.
Adds a persistent status bar to the CLI showing model name, context
window usage with visual bar, estimated cost, and session duration.
Responsive layout degrades gracefully for narrow terminals.
Changes:
- agent/usage_pricing.py: shared pricing table, cost estimation with
Decimal arithmetic, duration/token formatting helpers
- agent/insights.py: refactored to reuse usage_pricing (eliminates
duplicate pricing table and formatting logic)
- cli.py: status bar with FormattedTextControl fragments, color-coded
context thresholds (green/yellow/orange/red), enhanced /usage with
cost breakdown, 1Hz idle refresh for status bar updates
- tests/test_cli_status_bar.py: status bar snapshot, width collapsing,
usage report with/without pricing, zero-priced model handling
- tests/test_insights.py: verify zero-priced providers show as unknown
Salvage fixes:
- Resolved conflict with voice status bar (both coexist in layout)
- Import _format_context_length from hermes_cli.banner (moved since PR)
