Let me lay out the plan. + │ + │ ## What the "sample" actually is today + │ + │ The ring-buffer sample is assembled in `app/sampling.py:_collect()` from four collector dicts, + │ plus disk rates, then stored in `HistoryStore` as `tuple[float, dict[str, float | int | None]]`. + │ The full field set (no collector overlaps): + │ + │ | Field | Type | Producer | + │ |---|---|---| + │ | `cpu`, `cpu_temp`, `load1/5/15` | `float` / `float\|None` | `cpu.py` | + │ | `mem_used/total`, `mem_pct`, `swap_used/total`, `swap_pct` | `int`/`float` | `mem.py` | + │ | `gpu`, `vram_used/total`, `vram_pct`, `gpu_temp`, `gpu_name` | mixed | `gpu.py` | + │ | `battery`, `battery_status`, `ac_online` | `int\|None`/`str\|None`/`bool\|None` | `power.py` | + │ | `io_read`, `io_write` | `float` | `disks.rates()` | + │ + │ `net.sample()` is **not** in the buffer (fetched live per overview request) and stays a dict. + │ `procs.sample()` is a different list-of-dicts concern, untouched. + │ + │ ## The plan + │ + │ **1. New `app/sample.py`** — a `@dataclass Sample` with one typed field per row above, all with + │ defaults (`Sample()` is a valid blank), plus a `ts: float = 0.0`. + │ + │ **2. Collectors switch to a fill pattern** (no dict merging needed since fields don't overlap): + │ - `cpu.fill(s)`, `mem.fill(s)`, `gpu.fill(s)`, `power.fill(s)` — each sets only its own fields + │ on the passed-in `Sample`. GPU internals (`_amd_sample`/`_nvidia_sample`) become + │ `_amd(s)`/`_nvidia(s)` returning `bool`; the "no GPU" case is just the dataclass defaults. + │ - `disks.rates(prev, dt)` returns `tuple[float, float]` (read, write) instead of a 2-key dict. + │ + │ **3. `sampling.py`** — `_collect() -> Sample` builds one `Sample()` and calls the four `fill`s; + │ the loop assigns `sample.io_read, sample.io_write = disks.rates(...)`. + │ + │ **4. `state.py`** — `HistoryStore` becomes `deque[Sample]`; `record()` stamps `sample.ts = + │ time.time()`; `snapshot() -> list[Sample]`; `latest() -> Sample | None`. + │ + │ **5. `routers/overview.py`** — the main type-safety payoff: + │ - `overview()`: `s = store.latest() or Sample()`, then attribute access (`s.cpu`, `s.mem_used`, + │ …) into the existing `c` render dict. Template unchanged. + │ - `_window(snap: list[Sample], …)`: iterate `dataclasses.fields(sample)` with the existing + │ `isinstance(v, (int, float)) and not bool` filter to collect metric values; **explicitly skip + │ `ts`** (it's the x-axis, not a metric). `RowAgg` and the null-padding behavior are preserved. + │ + │ No circular imports (`sample.py` imports nothing from `app`). Verified only `state.py`, + │ `sampling.py`, `overview.py` + the collectors touch this data. + │ + │ ## Two judgment calls to flag + │ + │ 1. **`ts` folded into `Sample`** — I'm making a sample a self-describing "reading + when", so + │ the store is just `deque[Sample]`. Cost: `_window` must skip `ts`. Alternative: keep `ts` + │ separate (`deque[tuple[float, Sample]]`) and keep `_window` fully generic. I prefer folding it + │ in, but happy to keep it separate. + │ 2. **Empty-buffer startup** — `store.latest() or Sample()` means the first ~2s (before the first + │ sample lands) render zeros/“no GPU” instead of the current dashes, because numeric fields are + │ now tight-typed rather than `None`. Minor cosmetic, only affects startup. + │ + │ Want me to proceed with both as-is, or keep `ts` separate / preserve the startup dashes? + │ + │ tokens 2361 in 9147 out 31250 cached 0 written $0.0000 stop + + + │ 2026-08-30 20:03:09 • user + │ + │ folding in ts is ok, that makes the code more readable + + + │ 2026-08-30 20:03:09 • assistant • Qwen3.8-27B-Think @plan + │ + │ The user confirmed folding ts in is fine.
