Slice 0 of the bottom-up Rust rewrite (inbrace-tech#27): the crate skeleton so every later slice lands its module + test against a green build. - rust/ single binary crate 'tokenline', flat src/, edition 2024, MSRV 1.85. - deps: serde + serde_json + jiff (jiff::Timestamp for ISO-8601, lands slice 3). - panic = "unwind" in the release profile (the final slice's catch_unwind needs it). - main.rs is a stub; lib.rs is the module root. cargo build/run/test green (0 tests).
Slice 1 (inbrace-tech#27). Pure formatting helpers matching the bash fmt_k (awk %.1f token compaction) and fmt_eta (human ETA from seconds). Covered by #[cfg(test)] with the tier boundaries and the golden's 3d4h reset ETA.
Slice 2 (inbrace-tech#27). The COLOR_* / STYLE_* constants from tokenline.sh:21-30 as exact SGR sequences (RESET is [00m, BLINK [1;5m — byte-identical so the golden oracle diffs clean). Test asserts each against the bytes captured from bash output.
Slice 3 (inbrace-tech#27). Replaces the bash epoch_from_iso (date -d) with jiff::Timestamp parsing -> epoch seconds; None on malformed input. Transcripts and rate-limit resets are fixed-format UTC, so no tz database. Tests cover exact UTC epochs, sub-second truncation, and invalid input.
Slice 4 (inbrace-tech#27). Parses the host's stdin JSON into a typed Session (model, context, rate limits, per-turn token usage) with serde, plus the derivations (Gemini detection, subagent/antigravity transcript-path fixups) matching tokenline.sh. Unit-tested.
Slice 5 (inbrace-tech#27). compute(session, ttl_label) -> Option<Economics>: the per-turn equivalent-token and saving-% math byte-identical to tokenline.sh (multipliers, truncating eq/uncached_eq, integer saving_pct; write mult 2x on a 1h TTL). Pure values only — coloring is render's job. None when there's no turn activity.
Slice 6 (inbrace-tech#27). compute(session, now) -> Vec<RateLimit> for the 5h/7d windows: pct, ETA from resets_at (via jiff), 10-wide bar fill, severity + blink by pct, and the pace heuristic (VeryFast/Fast) all byte-identical to tokenline.sh's rl_segment. Empty for Gemini / absent windows. Values only; render applies color.
Slice 7 (inbrace-tech#27). runtime_dir() forking XDG ($XDG_RUNTIME_DIR/tokenline-$UID) on unix vs %LOCALAPPDATA%\\tokenline on windows, chmod 0700 behind cfg(unix); the per-session cache file (consolidated, one per session). fs only, no session input ever persisted. Unit-tested.
Slice 8 (inbrace-tech#27). Reads the last-turn timestamp from the transcript JSONL (falling back to the persisted cache), derives the 5m/1h TTL window, warmth and the countdown — the stateful edge over cache. ISO parsing via jiff (crate::fmt). Values only; render colors the HOT/COLD state. Unit-tested.
Slice 9 (inbrace-tech#27). render(raw, now, cache_dir) -> String assembles all three lines + divider byte-for-byte with tokenline.sh: model|ctx|cache line (ctx value in bold 16-color, cache countdown + HOT/COLD), the per-turn economics line, and the rate-limit bars/pace. Golden test asserts exact bytes against the fixed bash output for healthy_claude.json at a fixed clock. Recomputes the 5-tier cache color from remaining_secs (CacheInfo::warmth only carries 3 buckets).
Slice 10 (inbrace-tech#27). stdin -> now -> cache dir -> render -> write -> exit(0). A panic hook + catch_unwind turn any panic into empty output and a clean exit; writes go through write_all so a closed pipe never raises; malformed/empty stdin is a silent no-op. e2e tests drive the real binary to prove exit 0 + no output on garbage and empty input.
Slice 11 (inbrace-tech#27). tests/golden.rs is the parity gate: byte-exact healthy fixture under a frozen clock, plus the branch cases (Gemini hides rate limits, an idle turn hides the cost line, a fast burn flags pace + one ETA), and an ignored parse+render micro-benchmark. Consolidates the render golden out of render.rs. Adds .github/workflows/rust.yml: fmt + clippy/test on Linux/macOS/Windows + MSRV 1.85 build, fanned into a single required 'Rust' check (the Windows leg runs the real binary via stdin — the runs-on-Windows done-criteria).

Part of the parity-v1 stack for #27 — slice 11 of 11, bottom-up.
Stacks on #53 (the previous slice). This slice adds: tests/golden.rs (byte-exact + branch cases) and .github/workflows/rust.yml (3-OS + MSRV 1.85).
Merge order: #42 (bash resets_at fix) -> #43 (slice 0 · scaffold) -> then slices 1..11 in order -> this is slice 11.
Whole stack is green: ~31 tests (lib + golden + e2e),
clippy -D warningsclean,cargo fmtclean. Render is byte-exact vs the fixed bash oracle (tests/golden.rs).
