   - **PIVOTED 2026-05-28 → per-pane context-fill indicator (replaces the panel).** User decided lifetime token totals + $ aren't worth it on a subscription; what's actionable is *current context-window occupancy* per pane (spot the one needing `/compact`). Removed `UsagePanel`, the 💰 titlebar chip, and `Ctrl+Shift+U`. Repurposed `usage.rs`: `get_pane_context` returns each recent session's **current** occupancy = the LAST assistant turn's `input + cache_read + cache_creation` tokens (verified ~274k on this 1M session). `src/lib/usage.ts` now does window inference (200k vs 1M by whether occupancy already exceeds 200k — model id doesn't encode the variant), %, color ramp. App polls 15s (visibility-gated) → `cwd→SessionContext` map via orchestration; `LeafPane` renders a slim fill bar + % in the header, matched by `leaf.cwd`. **Also fixed narrow-pane toolbar** (user report: close × clipped when slim): a `ResizeObserver` in LeafPane sets `leaf--narrow`/`leaf--xnarrow` tiers; label shrinks first, split/status/secondary chips drop by tier, close × + context indicator stay pinned-right + visible down to the 180px min. Plan: `~/.claude/plans/greedy-cooking-flask.md` (rewritten for the pivot). **Pending Windows runtime verify.** Window-size 200k/1M is inferred (approx near boundary); `~`-spawned / cd'd panes may not match their session.
   - **Windows test 2026-05-28:** narrow-pane toolbar reflow (close × stays visible when shrunk, leaf--narrow/xnarrow tiers) **VERIFIED working.** BUT the context bar **does not show** — root-caused: it keys on `leaf.cwd`, which is ~always `undefined` (`newLeaf` sets no cwd; the shell picker never supplies one; only split-inheritance propagates it). So the cwd↔transcript match never hits for normal panes. Needs the pane's *live* cwd to work — leading options: capture via OSC 7 (default WSL bash under tiletopia doesn't emit it → would need injecting a PROMPT_COMMAND at spawn, shell-specific), or an "active pane shows its distro's currently-active session" heuristic gated on recent mtime. Decision pending with user.
   - **Fix implemented 2026-05-28 (OSC 7 live cwd, user chose this) — PENDING re-test.** `pty.rs` Wsl arm now sets `PROMPT_COMMAND` (forwarded via `WSLENV=…:PROMPT_COMMAND/u`) to `printf '\033]7;file://%s%s\033\\' "$HOSTNAME" "$PWD"` so the shell emits OSC 7 each prompt; default Ubuntu bash inherits an env-provided PROMPT_COMMAND (a hard-assigning rc or non-bash shell won't report → bar hidden, no breakage). `XtermPane` registers `term.parser.registerOscHandler(7, …)`, decodes the path, fires new `onCwd` prop. `LeafPane` tracks `liveCwd` and matches on `(liveCwd ?? leaf.cwd)`. OSC 7 fires at the bash prompt right before `claude` launches → `liveCwd` = claude's launch cwd; also follows `cd`. **If still blank after re-test:** check the shell actually emits OSC 7 (it won't if the user's rc hard-sets PROMPT_COMMAND, or default shell isn't bash) and that backend `get_pane_context` returns sessions (UNC/$HOME probe).
+  - **Windows test #2 2026-05-28 (OSC 7) + refinements:** OSC 7 injection **confirmed working** (`echo $PROMPT_COMMAND` shows our printf; a fresh pane lit up). Two issues found + fixed: (1) **bars appeared on plain bash panes** sitting in a dir that once had a claude session → added a **recency gate** (`CONTEXT_ACTIVE_MS = 10min`): only show when the matched session was written recently, so it tracks a live claude not a dormant transcript. (2) **The `[1m]` 1M-context marker is NOT in the transcript** — model id is bare (`claude-opus-4-7`), `[1m]` is display-only in `/context`. So the 200k-vs-1M window is unknowable from transcripts; the old `<200k→200k` guess overstated % for 1M users (42k read 21% vs claude's real 4%). Fix: indicator **label now shows absolute token count** (`formatTokens`, accurate regardless of window); the fill bar **assumes 1M**. A long-running claude pane spawned by the OLD binary won't have OSC 7 → no bar until respawned. **Still pending: confirm a freshly-spawned claude pane shows the right number.**
   - **Superseded — original lifetime-token panel refinements (kept for history):** (1) **Scope** — panel + titlebar chip now default to sessions matching open panes ("this workspace"), with an "open panes / all recent" toggle. The first cut summed *every* recent session on the distro (all projects, `/mnt` + home), which read as inflated. **Investigated the "double counting mounted folders + projects" report: NOT a real double count** — every transcript file is read exactly once, and no two project dirs share a cwd because claude resolves symlinks/mounts to the real path before mangling the project-dir name (e.g. the `~/claude/projects/tiletopia → /mnt/d/dev/tiletopia` symlink yields only `-mnt-d-dev-tiletopia`). The inflation was purely the global scope. (2) **Metric framing** — user is on a Pro/Max subscription where $ is meaningless (and `/usage` rate-limit quota can't be derived from transcripts); **tokens are now the headline**, the API-cost estimate is a labeled secondary `~$` kept visible so the user can validate it against real API billing at work. **Open question:** accuracy of the $ estimate vs actual API billing — user will check at work.
