Works in Renko + Candles.\n2. **Last-price legend** — dashed horizontal line at the live last price\n (`snapData.latest.price`, falls back to last visible bar close) + a filled\n TradingView-style price box on the right axis (green/red vs previous bar\n close). Under the box: `HH:MM · Xm ago` last-candle timestamp + age,\n color-coded green ≤6m, orange ≤15m, red older.\n3. **Right-edge label queue** — ALL right-side labels (indicator values,\n daily lines, step lines, price box) are collected via\n `queueRight(y, text, color, opts)` in `drawChart()` and drawn by\n `resolveAndDrawRightLabels()` (sort + forward push-down + backward pull-up,\n per-label topPad/botPad). `opts.box=true` draws a filled tag; `opts.sub`\n adds a second caption line.\n\n## Pitfall — never draw right-edge labels inline\n\nThe `padR=140` right gutter is shared by every legend. Before the queue,\neach label did its own `fillText(W - padR + …)` and overlapped freely.\n**Any new right-side label MUST call `queueRight(...)`** — do not add inline\n`fillText` in the gutter, it will collide. `drawDailyStep()` takes an\noptional trailing `queue` arg for this.\n\n## Frontend edit workflow (no restart needed)\n\n1. Backup: `cp static/index.html static/index.html.bak.YYYYMMDD_<feature>`.\n2. Edit; keep using the `F(px)` font-scale helper (A−/A+ button) and the\n `C.*` color constants.\n3. Syntax check: extract the `<script>` block and `node --check` it (node is\n installed on the VPS).\n4. Verify live: `curl -s https://tcharts.openalgo.theworkpc.com/index.html | md5sum`\n must equal `md5sum static/index.html` — nginx serves the file directly,\n so a match means it's live; user hard-refreshes. No `systemctl restart`\n (the Rust binary is untouched by static edits).\n5. Coordinate system notes: `parseTs()` treats API `ts` strings as IST and\n returns a true UTC epoch, so `Date.now()/1000 - parseTs(ts)` is a correct\n age in seconds. Chart geometry is saved in `chartLayout` for the crosshair\n — keep `padL/padR` values ... [4000 chars total, truncated]

Boot: `fill_symbol()` for every symbol\n (~4s total — incremental), then `run_watcher()` every 60s via tokio::spawn.\n- **Incremental append**: `fill_symbol()` rebuilds bricks + indicators in\n memory from full history (fast, deterministic), then compares the DB tail\n (`MAX(brick_index)` + close). Match → INSERT only newer rows. Mismatch or\n empty table → DELETE + rebuild THAT INTERVAL only. Everything for one\n interval in ONE transaction. No global DELETEs — old rows never rewritten\n (raw 5-min candles are immutable, so bricks/snapshots are append-only).\n- **WAL mode + busy_timeout(15s)** on writer (fill_symbol) and readers\n (`open_computed`, `read_5min_db`) — API never blocks or sees partial data.\n- **Hot/cold tiers**: browser POSTs `/api/watch {\"symbol\":\"SBIN\"}` every 30s\n while the page is open. Watcher: HOT symbols (heartbeat < 3 min) recompute\n every cycle when the raw 5-min DB mtime is newer (>5s grace); COLD symbols\n only every 15th cycle. `ensure_fresh()` at the top of every computed-DB\n reader endpoint (`api_bricks/snapshots/daily_values/xover_events/\n daily_signal`) fills on-demand when stale (FILL_LOCK mutex + spawn_blocking)\n — first open of a cold symbol costs ~0.5-2s once, then it's hot.\n- **Incremental API**: `/api/bricks/<sym>?interval=5m&since=<brick_index>&\n limit=<N>` — `since` returns only newer bricks, `limit` returns last N;\n response includes `max_index`. Works on both the pre-computed path and the\n custom-brick_size on-the-fly path.\n- **Frontend**: initial load fetches `limit=max(2000, bars*2)` bricks (not\n full history — BANKNIFTY has 284k); then `refreshIncremental()` every 60s\n appends `since=<lastIdx>` + refreshes snapshot tail (limit=500) +\n daily-values ...
