fix(git): move review and CI refreshes off render path

Serve PR and CI widgets from a versioned disk cache and refresh stale or missing data in a detached helper so slow GitHub CLI requests cannot block Claude Code's status line.

Request statusCheckRollup only when a CI widget needs it, deduplicate background refreshes with recoverable lock files, and share a single deadline across GitHub fallback attempts. Restrict metadata retries to CI-field compatibility failures.

Preserve upgrade compatibility with legacy raw JSON and empty negative-cache files, while marking new entries with whether CI checks were queried. Add regression coverage for migration, stale reads, cache upgrades, lock recovery, and timeout behavior.

Bump the package version to 2.2.25.

 ## 🆕 Recent Updates
 
-### v2.2.9 - v2.2.11 - GitLab support, reset timers, context, compaction, and git widgets
+### v2.2.22 - v2.2.24 - Powerline flex mode, cache/CI/sandbox visibility, layout controls, composable metrics, and safer config
+
+![Powerline Flex Mode](https://raw.githubusercontent.com/sirmalloc/ccstatusline/main/screenshots/powerline-flex.png)
+
+- **⏳ Prompt cache timer** - Added a `Cache Timer` widget with live `HOT` state, TTL countdown, configurable 5-minute/1-hour windows, and customizable state glyphs.
+- **✅ GitHub CI status** - Added a `Git CI Status` widget that summarizes failing, pending, and successful checks for the current branch's pull request.
+- **🔒 Sandbox status** - Added a `Sandbox Status` widget with glyph, text, and Nerd Font formats that follows Claude Code's layered sandbox setting on each refresh.
+- **↔️ One-sided default padding** - Default widget padding can now apply to both sides, the left only, or the right only in standard and Powerline layouts.
+- **⚡ Powerline flex mode** - Flex separators now work in Powerline mode, letting Powerline status lines right-align content or absorb available width.
+- **🌗 Per-widget dim styling** - The color editor can dim an entire widget or only parenthesized text, with reset and clear-all actions covering dim state.
+- **🧯 Safer settings recovery** - Invalid `settings.json` files are left untouched, defaults render in memory, and the status line shows an invalid-config warning.
+- **🧭 Selective Powerline alignment** - Press `x` in the line editor to let a widget and the rest of its line keep their natural widths while earlier Powerline columns stay auto-aligned.
+- **📏 Git widget width limits** - `Git Branch` and `Git Root Dir` can cap their visible width with ellipsis-safe truncation while preserving hyperlink targets.
+- **🔣 Current directory glyphs** - `Current Working Dir` can prepend an optional custom glyph, including in raw-value mode.
+- **🧠 Configurable context fallback** - `CCSTATUSLINE_CONTEXT_SIZE_FALLBACK` overrides the default 200k last-resort context window when Claude Code and the model name do not report one.
+- **🧩 Composable compaction metrics** - `Compaction Counter` can render count, auto, manual, unknown, or reclaimed-token values independently for custom layouts.
+- **🏷️ CLI version flag** - `ccstatusline --version` now prints the installed package version and exits.
+- **🛡️ Guarded invalid-config saves** - The TUI warns when it loaded defaults for an invalid settings file and requires confirmation before replacing that file.
+- **🔄 Usage display and cache fixes** - Used/remaining direction now works in every percentage mode, account switches invalidate cached usage, and fetch locks no longer cause repeated requests or stale timeout output.
+- **⏱️ Calmer reset timer startup** - Reset timers show labeled loading placeholders instead of transient rate-limit errors while Claude Code's embedded usage-window data is still arriving.
+- **🔇 Quieter install detection** - Best-effort npm and Bun probes no longer leak expected package-manager errors into the TUI.
+
+### v2.2.21 - Cache widgets, compaction details, extra usage currency, and package fixes
+
+- **🔣 Custom widget glyphs** - Git and JJ symbol widgets can override or suppress their built-in glyphs from the TUI.
+- **🔁 Compaction counter details** - `Compaction Counter` now counts explicit `compact_boundary` markers and can optionally show trigger splits plus tokens reclaimed.
+- **💸 Extra usage improvements** - Added `Extra Usage Used` and formats extra usage amounts with the billing currency reported by the usage API.
+- **📏 Custom command width context** - `Custom Command` widgets receive `terminal_width` in stdin JSON when ccstatusline can detect the terminal width.
+- **🧠 Prompt cache widgets** - Added `Cache Hit Rate`, `Cache Read`, and `Cache Write` widgets with turn/session scopes and hide-when-empty behavior.
+- **🔢 Token rounding fix** - Token counts from `999950` through `999999` now render as `1.0M` instead of `1000.0k`.
+
+### v2.2.20 - Gradients, token accuracy, usage reliability, and Git PR/MR fixes
+
+- **🌈 Gradient colors** - Added per-widget and whole-line foreground gradients with named presets, custom hex stops, TUI picker support, and Powerline-aware rendering. Press `g` on the Edit Colors screen for widget gradients, or press `g` for Override FG Color in Global Overrides for a line-wide gradient.
+- **🎯 More accurate token counts** - `Tokens Input` and `Tokens Output` now prefer cumulative transcript metrics before falling back to context-window totals.
+- **💸 Extra usage no-limit fix** - Extra usage widgets no longer get stuck on `[Timeout]` for accounts with overage enabled but no monthly limit configured.
+- **🔁 Compaction glitch filtering** - `Compaction Counter` ignores transient below-1% context readings so incomplete status frames do not create false compaction counts.
+- **🔀 SSH alias Git PR/MR detection** - Git PR/MR detection resolves SSH host aliases while preserving canonical GitHub and GitLab hosts for CLI selection and fallback repo links.
+- **🧪 Usage test cache isolation** - Usage-fetch test probes now isolate `HOME`, `USERPROFILE`, `CLAUDE_CONFIG_DIR`, and proxy variables so local tests cannot touch the real ccstatusline cache.
+- **📦 Dependency refresh** - Refreshed React/React DOM and Bun lockfile development-tooling resolutions for the release.
+
+### v2.2.14 - v2.2.19 - Version pinning, npm provenance, usage overage widgets, and Git lock avoidance
+
+- **📌 Version pinning support** - Added support for pinned global installs so Claude Code can keep running a specific ccstatusline version.
+- **🔐 npm provenance attestations** - Published packages now use trusted publishing provenance so users can verify where releases were built while avoiding long-lived npm publish tokens.
+- **🔄 Moving from auto-update installs** - If you currently use an auto-updating install, use the TUI uninstall option first, then reinstall to go through the version pinning flow. Your ccstatusline settings are preserved when uninstalling.
+- **💸 Extra usage widgets** - Added Extra Usage Utilization and Extra Usage Remaining widgets for monthly pay-as-you-go overage limits, with null rate-limit buckets handled as zero usage.
+- **🔒 Git lock avoidance** - Git helpers now pass `--no-optional-locks` so background status checks avoid creating `index.lock` races.
+- **🧱 Older Git compatibility** - Git widgets avoid newer command forms so repository status works on older Git installations.
+- **⚡ Persistent Git cache** - Git command output is cached under `~/.cache/ccstatusline/git-cache` with configurable TTL and `.git/HEAD`/`.git/index` mtime checks to reduce repeated subprocess work.
+- **🧭 Install flow polish** - Pinned global install is now the default install option, with clearer wording for install and migration flows.
+- **🪟 Hidden helper processes** - Runtime child processes set `windowsHide` so helper commands do not open extra windows on Windows.
+- **📏 Terminal width override** - `CCSTATUSLINE_WIDTH` can provide an explicit terminal width when automatic probing is unavailable.
+
+### v2.2.13 - Weekly model usage, voice status, hooks, and docs
+
+- **📊 Weekly Sonnet/Opus usage widgets** - Added separate weekly usage widgets for Sonnet and Opus API buckets, matching Claude Code's `/usage` model split.
+- **🎤 Voice Status widget** - Added a widget that shows whether Claude Code voice input is enabled, with icon, text, word, and optional Nerd Font display modes.
+- **📉 Timer short bars** - Block Timer, Block Reset Timer, and Weekly Reset Timer now support compact short-bar progress displays.
+- **🔕 Quieter hook output** - Hook handling now suppresses no-op JSON output so non-status updates stay silent.
+
+### v2.2.9 - v2.2.12 - GitLab support, reset timers, context, compaction, and git widgets
 
 - **🦊 GitLab PR/MR support** - `Git Branch` and `Git PR/MR` now support GitHub, GitLab, and compatible self-hosted remotes, using `gh` or `glab` as appropriate.
 - **🔄 Status line refresh interval** - Installed configs can set Claude Code's `statusLine.refreshInterval` from the TUI when Claude Code >=2.1.97 supports it.
 - **🧭 Wrap-around TUI navigation** - Menu/list navigation and move/reorder modes now wrap at the first and last items.
 - **📋 Clone widget shortcut** - Press `k` in the item editor to duplicate the selected widget, with fresh Powerline background color for cloned Powerline items.
 - **📊 Short bar display modes** - Context percentage, Context Bar, Session Usage, Weekly Usage, Block Timer, and reset timer widgets can use compact bar variants.
+- **⏱️ Usage time cursor** - Session Usage and Weekly Usage progress bars can show the elapsed time position within the current usage window.
 - **🕒 Reset timer timestamps** - Block and Weekly Reset Timer widgets can show exact reset timestamps with compact formatting, 12/24-hour display, IANA time zones, and locale selection.
 - **🪟 Context Window widget** - Added a `Context Window` widget for total model window size, keeping `Context Length` focused on current context usage.
 - **🔁 Compaction Counter widget** - Added a `Compaction Counter` widget that tracks session context compactions, with icon/text/number formats, optional Nerd Font icon, and hide-when-zero behavior.
 - **🧮 Git file status widgets** - Added `Git Staged Files`, `Git Unstaged Files`, `Git Untracked Files`, and `Git Clean Status` for file counts and clean/dirty state.
-- **🧠 Thinking Effort updates** - Added `xhigh`, show `default` when no effort is set, mark unknown future effort levels with `?`, and track live status JSON plus `/effort` command changes.
+- **🏷️ Clear context percentage labels** - `Context %` and `Context % (usable)` now label rendered values as used or left when toggling used/remaining mode.
+- **⚡ More Powerline caps** - The Powerline separator editor now supports more than three start/end caps.
+- **🧠 Thinking Effort updates** - Added `xhigh`, show `default` when no effort is set, mark unknown future effort levels with `?`, and track live status JSON plus `/effort` command changes. Claude Code reports Ultracode as `xhigh` in status line data.
 - **🧮 More accurate token counts** - Streaming duplicate JSONL entries are deduped so token widgets do not overcount live Claude Code output.
 - **🏷️ Cleaner model display** - The Model widget strips trailing context suffixes like `(1M context)`; use `Context Window` when you want the total window size shown.
 - **🧹 Cleaner empty-widget separators** - Manual separators now collapse around widgets that render empty, avoiding dangling separators when hide-when-empty widgets disappear.

+Settings saves are atomic and preserve symlinked `settings.json` files by writing through the resolved target. Invalid or unreadable settings are never overwritten during load; `loadSettings()` returns in-memory defaults, records `getConfigLoadError()`, and renderer paths surface that state with an invalid-config warning badge. The TUI captures that load error, keeps a visible warning active, and guards both save paths with an overwrite confirmation until a valid configuration is saved.

+## Widget Data Sources
+
+- **Cache Timer** reads the transcript tail directly on every render. It expands the read backward when a trailing JSONL record exceeds the initial window, ignores sidechain and synthetic API-error rows, and anchors the countdown only on assistant requests with cache activity. It does not create a separate cache file.
+- **Git CI Status** extends the cached Git PR lookup with GitHub's `statusCheckRollup`. If the authenticated `gh` token cannot read checks, the lookup retries with PR metadata only so the Git PR widget still works.
+- **Sandbox Status** reads `sandbox.enabled` from Claude Code's layered project-local, project, user-local, and user settings on every refresh. This reflects `/sandbox` file updates but remains a best-effort indicator when managed or CLI settings take precedence.
+
 ## Build Notes
 
 - Build target is Node.js 14+ (`dist/ccstatusline.js`)
+- `postbuild` replaces the bundled `__PACKAGE_VERSION__` placeholder from `package.json`; `ccstatusline --version` reads that value and exits before mode detection
 - During install, `ink@6.2.0` is patched to fix backspace handling on macOS terminals

 ### Tokens, Usage & Context
 
-- **Tokens Input** / **Tokens Output** / **Tokens Cached** / **Tokens Total** - Show current-session token counts.
+- **Tokens Input** / **Tokens Output** / **Tokens Cached** / **Tokens Total** - Show current-session token counts. Input/output prefer cumulative transcript metrics and fall back to `context_window.total_input_tokens` / `context_window.total_output_tokens` when transcript metrics are unavailable; cached/total use transcript metrics.
+- **Cache Hit Rate** / **Cache Read** / **Cache Write** - Show prompt-cache efficiency. Cache Hit Rate uses cache reads divided by cache reads plus cache writes; Cache Read and Cache Write include each value's share of prompt context. They default to the latest turn from `context_window.current_usage`, can switch to cumulative session totals, and can hide when empty.
+- **Cache Timer** - Estimate time remaining before the current prompt-cache entry expires. It shows `HOT` while a main-chain turn is active, then counts down from the latest assistant request with cache activity and becomes `COLD` just before expiry. The default TTL is 5 minutes; it can switch to 1 hour, hide when no cache anchor is available, and customize the glyph for each state. Because Claude Code transcripts expose cache token activity rather than the actual expiry timestamp, the countdown is best effort.
 - **Input Speed** / **Output Speed** / **Total Speed** - Show session-average token throughput with an optional per-widget rolling window (`0-120` seconds; `0` = full-session average).
-- **Context Length** / **Context Window** / **Context %** / **Context % (usable)** / **Context Bar** - Show current context length, total context window size, usage percentage, usable-window percentage, or a progress bar.

+- **Context Length** / **Context Window** / **Context %** / **Context % (usable)** / **Context Bar** - Show current context length, total context window size, used/remaining percentage, usable-window percentage, or a progress bar. The window size is taken from Claude Code's reported `context_window.context_window_size` when present, then from a model-name hint (e.g. a `[1m]` suffix), and finally from a fixed fallback. Set `CCSTATUSLINE_CONTEXT_SIZE_FALLBACK` to a positive integer to override that last-resort fallback (defaults to `200000`) — useful when an older Claude Code does not report the window size for a 1M-context model, so the bar would otherwise read against 200k.

Two optional, independent per-item add-ons toggle extra detail: a trigger split (`↻ 3 (2 auto, 1 manual)`; a compaction whose trigger is missing or unrecognized is bucketed as `unknown`) and tokens reclaimed (`↻ 3 ↓887.0k`, each compaction's `preTokens - postTokens` floored at 0 and summed, shown only when greater than 0 — so very old transcripts predating the `postTokens` field display nothing). Its value selector can instead render the total count, one trigger count (`auto`, `manual`, or `unknown`), or reclaimed tokens as a standalone value; hide-when-zero applies to the selected value.
+- **Session Usage** / **Weekly Usage** / **Weekly Sonnet Usage** / **Weekly Opus Usage** / **Extra Usage Utilization** / **Extra Usage Remaining** / **Extra Usage Used** / **Block Timer** / **Block Reset Timer** / **Weekly Reset Timer** - Show usage percentages, monthly pay-as-you-go overage usage, and current block/reset timing. The all-models weekly bar covers `seven_day` from the usage API; the per-model variants surface the `seven_day_sonnet` and `seven_day_opus` buckets that Claude Code's own `/usage` panel shows. Session Usage, the weekly percentage widgets, and Extra Usage Utilization can show either used or remaining percentage in every display mode. Session and weekly usage bars can also show a time cursor. Extra usage widgets accept known extra-usage state as complete when an account has no monthly limit configured, avoid repeated refetches and stale `[Timeout]` output, and format amounts with the API-reported billing currency when available. Reset timers can show remaining time, progress, or exact reset date/time with timezone and locale controls; while reset data is still arriving at startup, they show a labeled loading placeholder instead of a transient API error.

 - **Full width minus 40** - Reserves 40 characters for auto-compact message to prevent wrapping (default)
 - **Full width until compact** - Dynamically switches between full width and minus 40 based on context percentage threshold (configurable, default 60%)
 
+Flex separators expand against the detected width in both regular and Powerline rendering. If width detection is unavailable, they render like normal separators until a terminal width is available.
+
+If ccstatusline cannot detect your terminal width, set `CCSTATUSLINE_WIDTH` to a positive integer to override probing:
+
+```bash
+CCSTATUSLINE_WIDTH=160 ccstatusline
+```
+
+The override is checked before automatic width detection, so it also works in wrapper processes, IDE integrations, nested PTYs, and Windows environments where probing may be unavailable. Invalid values such as `0`, negative numbers, or non-numeric strings are ignored and ccstatusline falls back to normal detection.

+Powerline Setup can align widgets into shared columns across multiple status lines; press `a` there to toggle **Align Widgets**. When auto-alignment makes a naturally wide value stretch later columns, select that widget in the line editor and press `x` (**exclude align**). The selected widget and everything after it on that line keep their natural widths, while earlier columns remain aligned.

You can adjust this setting to 1 to disable the contrast enforcement, or use a standalone terminal for accurate colors.

+
+## Gradient Colors
+
+A foreground color can be a multi-stop **gradient** instead of a solid. Colors interpolate in OKLab for perceptually even blends. A gradient value takes one of three forms, all prefixed `gradient:`:
+
+- **Named preset** — `gradient:atlas` (case-insensitive). Built-in presets: `atlas`, `cristal`, `teen`, `mind`, `morning`, `vice`, `passion`, `fruit`, `instagram`, `retro`, `summer`, `rainbow`, `pastel`.

+
+Gradients apply at **two scopes**:
+
+- **Per-widget** — set a widget's color to a gradient so its text carries its own self-contained sweep. In the color menu (foreground, 256-color or truecolor mode), press **(g)** to open the gradient picker, then choose a preset or enter custom start/end hex stops.
+- **Whole line** — set `overrideForegroundColor` to a gradient spec to paint the entire status line with one continuous sweep, each character colored by its column position. In the Global Overrides menu, press **(g)** on Override FG Color to open the same gradient picker, or author the value directly in `settings.json`.
+
+Gradients self-degrade where they can't render: at Basic or No Color levels, gradient settings are preserved but render as plain text. In Powerline mode, global foreground gradients color widget text while separators and caps keep Powerline's normal foreground/background contrast rules; per-widget gradients collapse to their first stop when using 256-color or truecolor output.

 ## Claude Code Status Line Settings
 
 When ccstatusline is installed in Claude Code, the main menu includes **Configure Status Line**. Claude Code versions >=2.1.97 support `statusLine.refreshInterval`; ccstatusline can set it to `1-60` seconds, defaults fresh supported installs to `10` seconds, and removes the setting when the input is left empty.
 
+## Settings Recovery

+   ```
+
+3. Set timeout: `2000` (the `curl` itself caps at 2s; the outer `|| true` keeps the widget silent on any failure)
+4. Leave "preserve colors" off — the output is a plain emoji + name list
+
+When every tracked service is operational the command prints nothing, so the widget renders empty and manual separators collapse around it. The endpoint is JSON, CORS-enabled, and served with a ~5-minute cache.

+## Integration Example: ccsessions
+
+[ccsessions](https://github.com/treebird7/ccsessions) is a CLI session manager for Claude Code. Its companion script `cc-session-num` shows the current session's rank (`#1`, `#2`, …) matched against the same mtime-sorted list that `ccsessions` uses.
+
+1. Install `cc-session-num`:
+
+   ```bash
+   curl -fsSL https://raw.githubusercontent.com/treebird7/ccsessions/main/cc-session-num \
+     -o ~/.local/bin/cc-session-num && chmod +x ~/.local/bin/cc-session-num
+   ```
+
+2. Add a Custom Command widget
+3. Set command: `cc-session-num`
+4. Leave timeout at default (the script reads `~/.claude/projects/` locally and returns in milliseconds)
+
+The widget renders nothing when the current session isn't found, so manual separators collapse around it cleanly.
+
+> 📄 **How it works:** `cc-session-num` reads `CLAUDE_CODE_SESSION_ID` from the environment (set by Claude Code), then ranks `~/.claude/projects/*/*.jsonl` files by modification time — the same sort order `ccsessions` uses — and prints the matching position.

+ * - Returns `{ enabled: false }` when the manifest exists but `bridgeSessionId` is

+// Apply a gradient across the visible characters of a single widget's text,

+// passed through uncolored and does not consume a gradient step, and ANSI/OSC
+// escape sequences pass through untouched. The gradient restarts at t=0 for
+// each call, so every widget spans its own self-contained sweep.
+//
+// No trailing reset is emitted here - the caller appends `\x1b[39m`. At ansi16
+// (or for empty/blank text) the input is returned unchanged.
+//
+// KNOWN LIMITATION — code points, not grapheme clusters.
+// This walks `text` with `for…of`, which iterates Unicode *code points*, whereas
+// the whole-line `applyLineGradient` (in ansi.ts) walks *display clusters* via
+// `consumeDisplayCluster`. For plain text (ASCII, single-code-point emoji) the two
+// agree. They diverge only for multi-code-point grapheme clusters — ZWJ sequences
+// (👩‍👩‍👧), variation selectors (✏️), regional-indicator flag pairs (🇺🇸): this
+// function assigns a separate gradient step to each code point in the cluster
+// (compressing the sweep there) and emits color codes onto zero-width joiner /
+// selector code points that render nothing. The visible glyph still draws; the
+// cosmetic effect is a locally faster sweep plus a few inert escape bytes.
+//
+// This divergence is deliberately tolerated rather than fixed:
+//   1. Per-widget gradient text is short, author-controlled widget content — ZWJ
+//      emoji are vanishingly rare there (the whole-line path, which is far more
+//      likely to carry arbitrary cwd/branch text, IS cluster-correct).
+//   2. The correct walker (`consumeDisplayCluster`) lives in ansi.ts, and ansi.ts
+//      already imports from this module (gradient.ts) — depending on it back would
+//      introduce a circular import. Unifying the two would require first extracting
+//      the cluster walker into a third, dependency-free module. That refactor is a
+//      tracked follow-up, not a blocker for correct rendering of real status lines.
